Measures of Fengtai District on Responding to COVID-19 Epidemic and Supporting Enterprise Development (Provisional)

　　In order to thoroughly implement the spirit of the important instructions of the Supreme Leader General Secretary on resolutely winning the prevention and control of epidemic situation, fully implement the decision-making arrangements of the CPC Central Committee the State Council and the municipal party committee and municipal government on doing a good job in the prevention and control of epidemic situation in COVID-19, help enterprises tide over the difficulties and support the stable development of enterprises, the following measures are formulated.

　　First, strengthen support for key enterprises in epidemic prevention and control

　　To support the prevention and control of epidemic situations such as medical protective clothing and masks, it is urgent for medical material production enterprises to resume production and expand production capacity, and to help enterprises solve the problems of ensuring raw materials, factories, personnel, transportation and other factors in the process of resuming production. Give appropriate subsidies to enterprises that urgently need medical materials production and enterprises that provide space, property and other support, with a maximum of 1.5 million yuan. (Responsible unit: District Development and Reform Commission)

　　Second, open up a green channel for approval

　　We will speed up the examination and approval of new projects that produce materials needed for epidemic prevention and control, adopt a special way, and provide all-round services such as priority acceptance, on-site guidance and one-stop handling of administrative examination and approval items such as business license issuance, medical device production and business record permission. (Responsible unit: District Market Supervision Bureau)

　　Third, increase industrial financial support.

　　For key enterprises that meet the policies of "Several Measures for Optimizing Business Environment in Fengtai District" and "Measures for Zhongguancun Fengtai Science Park to Support the Development of High-tech Industries and Technological Innovation", the online declaration of policy funds in 2019 will be carried out, simplifying the application procedures for policy awards, speeding up the disbursement of funds and alleviating the operational pressure of enterprises. (Responsible units: District Development and Reform Commission, Fengtai Park Management Committee and District Finance Office)

　　Fourth, ease the credit pressure of enterprises

　　Take the initiative to accurately connect financial institutions for key enterprises in epidemic prevention and control, coordinate special credit support, and do not lend, keep lending or suppress loans to enterprises that have temporary difficulties in operation but have development prospects due to the epidemic. For enterprises that failed to be included in the special refinancing support scope of the People’s Bank of China during the epidemic period and met the industrial development direction of Fengtai District and made outstanding regional comprehensive contributions, banks in the region are encouraged to provide financial support for them and give a discount of 1.5 percentage points of the loan amount, and the discount amount for a single enterprise does not exceed 1 million yuan. The local government guarantee institutions launched "anti-epidemic loans" products to help small and medium-sized enterprises that are greatly affected by the epidemic to renew their loans and reduce the comprehensive rate by 0.5 percentage points. (Responsible unit: District Finance Office)

　　Five, reduce the cost of enterprise property

　　Small and medium-sized enterprises that lease the real estate belonging to state-owned enterprises directly under public housing and state-owned enterprises in the area to engage in production and business activities, adhere to business according to government requirements or close down in accordance with epidemic prevention regulations without layoffs or fewer layoffs, will be exempted from February rent; Leased for office space, 50% of the rent in February will be reduced. For renting other business premises, the owner (landlord) is encouraged to reduce or exempt the rent for the tenant, which shall be settled by both parties through consultation. For commercial buildings with outstanding regional comprehensive contributions recognized by the competent department of industry, if rent is reduced or exempted for small and medium-sized enterprises in line with the industrial development direction of Fengtai District, subsidies will be given at 30% of the amount reduced or exempted in February and March, with a maximum of 1 million yuan; Large shopping malls and shopping centers with outstanding regional comprehensive contributions recognized by the commerce department will be subsidized by 30% of the amount of rent reduction and exemption in February and March, with a maximum of 1 million yuan. (Responsible units: District Housing Management Center, District State-owned Assets Supervision and Administration Commission, Fengtai Park Management Committee, Lize Business District Management Committee, District Investment Promotion Service Center and District Commerce Bureau)

　　Sixth, support innovation and entrepreneurship carrier platform

　　Priority will be given to incubator funds for science and technology business incubators and creative spaces that reduce rents for small and medium-sized enterprises renting houses during the epidemic. (Responsible unit: District Science and Technology Information Bureau)

　　Seven, support enterprises to carry out epidemic prevention and control technology and product innovation.

　　Special funds for major scientific and technological projects in Fengtai District are given priority to enterprises involved in epidemic prevention and control. COVID-19’s scientific research projects in prevention, detection, diagnosis and treatment, as well as projects that apply artificial intelligence, cloud computing, big data and other technical means to epidemic prevention and control, will be given priority subsidies for the transformation of scientific and technological achievements after review by the competent authorities of the industry, with a maximum of 3 million yuan. For loans to small and medium-sized scientific and technological enterprises, the guarantee and evaluation fees will be reduced by 1.1 percentage points. Give priority to providing application scenarios for new technologies and new products related to epidemic prevention in the region. (Responsible unit: District Science and Technology Information Bureau)

　　Eight, support the stable operation of daily necessities supply and reserve enterprises.

　　During the period of epidemic prevention and control, large-scale commercial business entities that have made outstanding contributions to stable price and supply as determined by the commercial department will be given a one-time reward of 501 million yuan depending on the degree of contribution. (Responsible unit: District Bureau of Commerce)

　　Nine, increase the intensity of aiding enterprises to stabilize their posts

　　Expand online recruitment channels, make full use of Fengtai District’s "Everyone Employment Network" to publish job information, build a platform for employment service exchange, and ensure the stability of enterprise employment. To implement the policy of helping enterprises to stabilize their posts during the epidemic in Beijing, the insured enterprises that are greatly affected by the epidemic, face temporary production and operation difficulties and are expected to recover, and insist on not laying off employees or laying off fewer employees, can return the unemployment insurance premium according to the monthly per capita unemployment insurance premium standard and the number of insured employees in the previous year for six months. According to the growth of the average number of employees in enterprises at the end of April and the average number of employees in the previous year, enterprises are given moderate financial subsidies. For enterprises that enjoy the above policies, employees (including those waiting for posts) are organized to participate in vocational skills training that meets the requirements according to the post requirements, and they can enjoy one-time skills upgrading training subsidies according to the standard of 1000 yuan per person. Eligible unemployed people in this area can enjoy free training in accordance with relevant regulations. (Responsible unit: District Human Resources and Social Security Bureau)

　　X. Strengthening the guarantee of legal services

　　Set up a legal service group for small and medium-sized enterprises, and provide consulting and agency services for enterprises affected by the epidemic by "zero meeting" such as online and appointment, so as to reduce the business risks of enterprises. Provide specialized notarization services for small and medium-sized enterprises affected by the epidemic. (Responsible unit: District Judicial Bureau)

　　The above measures shall be implemented as of the date of issuance, and shall be valid for the period of epidemic prevention and control in COVID-19 (unless there is a clear time limit in the specific measures), and shall be interpreted by the District Development and Reform Commission in conjunction with the responsible units. In addition to enterprises directly involved in epidemic prevention and control identified by relevant departments, enterprises enjoying the above measures should register and pay taxes in Fengtai District. Enterprises shall not repeatedly enjoy similar subsidies to support funds. Small and medium-sized enterprises should comply with the Standard Provisions on the Classification of Small and Medium-sized Enterprises jointly issued by the Ministry of Industry and Information Technology, the National Bureau of Statistics, the National Development and Reform Commission and the Ministry of Finance (No.300 [2011] of the Ministry of Industry and Information Technology).

April 5

The ventilator "collective vacation" in Wuhan Thunder God Mountain hospital is waiting for disinfection and cleaning;

April 11th

The ICU ward of Jinyintan Hospital completed the clearing of COVID-19 patients;

April 14th

Thunder God Mountain hospital patients are cleared;

April 15th

Thunder God Mountain hospital officially closed the cabin

… …

At home, good news comes one after another!

Abroad, New York ordered 17,000 ventilators from China.

Even Tadpole Jun’s overseas friends said,

His mother insisted on buying him a ventilator on Taobao.

"I am so helpless. If medical ventilators can be bought on Taobao, how can there be such a shortage abroad?"

so

What is the difference between the ventilator in the hospital and the ventilator we usually say? Is it necessary for ordinary people to use medical ventilators? What kinds of medical ventilators are there?

Too long to read the version

Rescue breathing equipment can be roughly divided into:

Oxygen therapy equipment, ventilator and artificial lung (ECMO).

They have their own characteristics, and the diseases they aim at are different.

Healthy people, there is absolutely no need to buy it themselves.

Oxygen therapy equipment

When it comes to ventilators, many readers may immediately think of scenes in TV dramas. The attending doctor said, "Come on, the patient is dying." As soon as the voice fell, the nurse hurried to push the oxygen bottle. Oxygen bottles, oxygen bags and various oxygen generators on shopping websites all belong to oxygen therapy equipment.

Oxygen therapy equipment has two functions.

(1) directly provide oxygen for patients.

If we compare the human body to a jar, with one mouth sucking air and one mouth discharging waste gas, then the oxygen concentration in the jar must be kept constant because every cell needs a certain amount of oxygen. However, in some cases, the oxygen concentration in patients will drop. For example, the patient is in a plateau, and the oxygen in the air is insufficient, or the patient suffers from chronic obstructive pulmonary disease, and the trachea and bubbles are diseased, so no matter how hard he tries, he can’t breathe in too much air. What should we do? The answer is to increase the oxygen concentration in the air inlet, that is, to provide patients with higher concentration of oxygen through oxygen therapy equipment.

(2) as an oxygen source

Oxygen therapy equipment can also be connected to a ventilator as a source of oxygen. It can be seen from here that the ventilators mentioned by doctors are not the same as oxygen cylinders and oxygen generators.

Hyperbaric oxygen chamber is a special oxygen therapy equipment. In other words, it is essentially an oxygen cylinder, but it can be as big as a room. The atmospheric pressure inside is usually three times the normal pressure, and accordingly, its oxygen concentration is very high.

There are two common uses of hyperbaric oxygen chamber.

One is to deal with anaerobic bacteria, which are afraid of oxygen; The second is to treat carbon monoxide poisoning. For the human body, hemoglobin is equivalent to a trolley for transporting oxygen, and carbon monoxide can occupy hemoglobin, thus affecting the supply of oxygen. High concentration oxygen must be used to drive away carbon monoxide in order to save the patient’s life.

Because of the high oxygen concentration, hyperbaric oxygen chamber is a very prone to fire. Don’t say that playing with lighters, even static electricity accumulated on chemical fiber clothes may cause accidents. Therefore, if you need to use hyperbaric oxygen chamber treatment, you must strictly follow the guidance of medical staff.

Having said that, one more thing: all oxygen therapy equipment has a specific scope of application. Some sellers say that "regular oxygen inhalation can improve immunity and children’s performance" in order to increase the sales of oxygen generators. In fact, normal people don’t need these at all.

Noninvasive mechanical ventilation

Under normal circumstances, when inhaling, the muscles around the lungs are pulled outward to drive the alveoli to expand; Once the alveoli expand, the pressure inside is small, which can accommodate the gas from the outside. Covid-19, on the one hand, can directly damage alveoli and interfere with the expansion of alveoli, on the other hand, it will attract immune cells, and the fighting between them will inevitably cause inflammation and further aggravate atelectasis.

What should I do in this situation?

The answer is noninvasive mechanical ventilation.

Non-invasive means no wound; Machinery is the use of a ventilator; Ventilation means inhaling oxygen and expelling carbon dioxide. The motor in the noninvasive ventilator can compress oxygen, create pressure, and then, along the breathing mask, enter the patient’s lungs — — Whether the alveoli can expand or not, oxygen is directly injected into them.

Of course, this is just a general principle, which is actually much more complicated. The pressure produced by the ventilator can be positive pressure or negative pressure, which can be generated continuously or provided intermittently, and can be adjusted according to the patient’s situation; There are also many kinds of breathing masks, which can be used only for the nose, or to wrap the mouth, or to wrap the whole face of the patient.

Invasive mechanical ventilation

Pay attention to the news, and you will find that most of the ventilators mentioned recently are invasive ventilators.

The biggest difference between invasive mechanical ventilation and noninvasive mechanical ventilation is whether to establish an airway for patients. Some patients have claustrophobia and can’t accept breathing masks, some patients have facial trauma, which affects the fit of breathing masks, and some patients have a lot of sputum in their trachea, which seriously affects the effect of ventilation. Therefore, the doctor will make an incision in the patient’s trachea, insert a hose into it, and artificially establish a passage for air in and out.

Accordingly, the structure of invasive ventilator is more complicated. For example, an invasive ventilator is equipped with a battery, which can continue to work and care for patients’ lives even if the mains supply is interrupted or the emergency power supply fails in the hospital.

Therefore, the invasive ventilator is usually fully functional and can be used as a noninvasive ventilator in an emergency; Conversely, the non-invasive ventilator cannot be used as an invasive ventilator because of its limited function. This may be why most of the current foreign orders are aimed at invasive ventilators.

In vitro oxygen membrane bonding

In vitro oxygen membrane bonding is the ECMO that is often mentioned in the first two months.

Strictly speaking, it is not a ventilator.

Non-invasive ventilator and invasive ventilator are both helpers of the lung, and assist patients to breathe through masks or tracheal intubation; When ECMO is needed, it doesn’t matter whether the patient can breathe or not, it can take over breathing completely.

When using ECMO, we should first make an incision in the patient’s blood vessel to draw the blood out. Then, ECMO will expel carbon dioxide from it, inject enough oxygen and heat it properly; Finally, the blood with proper temperature and full of oxygen is sent to the patient’s blood circulation through the motor.

In other words, ECMO is equivalent to a weakened version of the time capsule, which can temporarily save the patient’s life. The key is whether doctors can find a solution to the fundamental problem in a limited time.

However, ECMO and ventilator have one thing in common: both need oxygen. During the closing period of Wuhan, many hospitals were short of oxygen because of the surge of patients. Those workers who work overtime to produce oxygen and transport oxygen are also great contributors to the fight against the epidemic.

The domestic epidemic situation has improved recently.

But before the advent of specific drugs and vaccines

Oxygen therapy, noninvasive ventilator, invasive ventilator and ECMO.

Is the most effective way for us to deal with novel coronavirus.

To make good use of them,

Not only need excellent medical staff,

But also the cooperation of manufacturing and transportation.

I hope that over time,

We can master these technologies thoroughly,

Better care for people’s health.

In the article "It’s time to break the myth of multivitamins", we talked about that the quality of multivitamins cannot be guaranteed, and the products may not completely contain the elements indicated in the instructions, or may contain pollutants harmful to human body. How to find reliable health care products? This paper provides some methods for your reference.

Writing | Shi Juan

With the improvement of living standards, "health preservation" has become a daily topic for Chinese people. In addition to the old ways, taking all kinds of health products has become the best choice for many Chinese people, especially the elderly. A study shows that by 2023, the nutritional supplement market in China is expected to reach 40 billion dollars, which will replace the United States as the largest nutritional supplement market in the world. There are many kinds of health care products in China market, both domestic and imported. Many people like to buy "imported" health care products, especially those from the United States, and feel that the prices are affordable and the quality is guaranteed.

However, are all American health products really good?

The rise of American health care products market

Since 1994, the American health care products market has experienced rapid development: sales in 1994 were only $4 billion, and in 2018, it has reached $42 billion. To a great extent, this increase can be attributed to a federal bill passed in 1994, entitled Dietary Supplement Health Education Act [1]. This law was initiated by some politicians who are inextricably linked with health care industry’s economy. The protection of health care products manufacturers is far more than that of ordinary consumers, which makes health care products completely unnecessary like prescription drugs, and can only be listed after strict examination and approval.

This bill relaxes the industry regulations, so that Dietary Supplement (also known as health products, including vitamins, minerals, plant extracts, etc.) can be sold in pharmacies or supermarkets without the prior approval of the US Food and Drug Administration (FDA). After the product enters the market, if consumers report adverse events after use, the FDA will intervene in supervision. The FDA will also conduct product sampling inspection from time to time. If it is determined that the supplement is adulterated, the FDA can send a public warning letter to the manufacturer or recall the products sold.

If you carefully look at the regulatory content of health care products on the FDA website, you can summarize the following important points:

1) Health products don’t need the approval of FDA.

2) American federal law does not require health care products to prove to FDA that the products are safe before going on the market.

Note: it is not proof of "effectiveness"! You don’t even have to prove safety!

3) The manufacturer does not need to prove to the FDA that the effect marked on the health care product bottle is accurate and true.

4) Generally speaking, the FDA began to formally monitor health care products after they were put on the market. Monitoring is only aimed at whether this product will cause great side effects to people and so on.

5) It is illegal for health care products to advertise that "it can cure a specific disease or delay a certain symptom". This is why health care products usually do not say that they can cure a specific disease, but only generally say that they can improve "immunity" and so on.

There are a large number of health products in the market, some of which are produced by large companies and some from very small companies. The production specifications of different companies are very different. The number of health care products is a whole order of magnitude larger than that of drugs, but the resources for supervision are limited, which means that the quality and safety of these health care products can only rely on the conscience of manufacturers and distributors before problems are found.

01 consumer’s misunderstanding

Made in America?

In Chinese, we often think that the quality of health care products abroad (such as the United States and Australia) is good. However, things are not what we imagined.

Although most health care products sold in the United States are produced in the United States, their raw materials usually come from other countries, of which more than 60% are from China, and only the last step of assembly is carried out in the United States. Manufacturers will often change the source of raw materials, and different batches of the same vitamin from the same manufacturer are likely to have different raw materials. The FDA of the United States does not require the country of origin of the ingredients on the bottles of health care products, nor does it require the country of origin. It only requires the telephone number or address of the manufacturer or distributor for consumers to contact. Because the address is not necessarily the place where the product is made, it is impossible to tell where the health care product comes from just by looking at the medicine bottle.

Photo: American-made health products. But the raw materials used may come from other countries.

The following three common health care products are basically produced in China:

① 90% of vitamin C comes from China. Scots also produce a small amount of vitamin C, but the cost of raw materials is three times that of China, so the price is much more expensive than that from China.

② At present, there is no manufacturer of biotin in other countries except China. Many so-called "Made in America" biotin is actually imported from China, and then ground and processed, and turned into American production.

③ Pure folic acid mainly comes from China. Like biotin, many folic acid claimed to be produced in the United States are imported from China and then ground in the United States. The only exception is 5- methyltetrahydrofolate (5-MTHF, a form of folic acid that is more easily absorbed and has better bioavailability), which is usually produced in the United States.

In the United States, the quality of health care products is also a big problem.

In 2015, the Attorney General’s Office of New York accused four major national retailers-GNC, Target, Walgreens (walgreen) and Walmart (Wal-Mart)-of selling fake and even potentially dangerous health products made of plant extracts [2].

The attorney general’s office tested the best-selling plant extract health care products on the shelves of these retailers, and found that four-fifths of the products did not contain any labeled plant ingredients, but only contained cheap fillers, such as rice flour, asparagus and indoor plant extracts (that is, artificially planted ordinary low-priced plants). In some cases, these substances may cause serious allergic reactions.

For example, Walgreens has a very popular self-produced brand of ginseng tablets, which claims to "improve physical endurance and vitality" and only contains garlic and rice powder. Walmart sells a ginkgo biloba extract, the real ingredients are radish, indoor plants and wheat flour, although the label claims that the product does not contain wheat and gluten. Of the six plant extract supplements tested by Target, three-Ginkgo biloba extract, St. John’s wort (St. John’s wort) and Valerian root-do not contain the ingredients on the label, but contain rice, beans and wild carrot powder. The same is true for GNC’s health care products, which use ingredients not indicated on the label as fillers, such as peanut and soybean powder, which is extremely dangerous for people with peanut allergy.

02

Natural = good?

There are still many people who think that health care products are mostly "natural" ingredients, so there will be no problem. However, even if it is extracted from natural animals and plants, the complexity of the animals and plants themselves (from the content of effective components to the pollutants that may be contained) and the industrial steps to be experienced in purification should be taken into account. Take some health care products made of plants, many different plants can be used to prepare health care products, but plants that look similar and are close in species may have very different effects. For example, many women take black cohosh extract to improve menopausal symptoms, but in the United States and Canada, consumers have suffered liver damage because the pills they take actually contain different substances with similar names.

"Natural" ingredients do not mean that they are good, and many natural substances are toxic. Toxic natural substances in food include cyanogenic glycosides in bamboo shoots, glycoalkaloids in potatoes, Furocoumarins in citrus plants (lemon, lime, grapefruit, bergamot), and many beans contain toxins called lectins. When the dose is reached, these natural toxins will cause many bad effects on people’s health, and some toxins will cause great damage as long as they are few. "Natural" ingredients are not worthy of superstition.

How to judge the quality of health products?

Because health care products don’t have to undergo rigorous clinical trials, there is actually no way to guarantee their effectiveness and safety, and there is no guarantee that they will not interact with any drugs you may take.

The only thing I can see is what is in this health care product. That is to say, does this health care product contain the ingredients it claims to have, the dosage is in line with the label, there is no pollution (such as lead and other heavy metals), and whether the ingredients can be released normally after taking the tablets.

Drugs can be tested for purity, so why don’t health products just do it?

Drugs are usually purified products, and the content of main components can even exceed 99.9%, with only a small amount of impurities. However, the ingredients of health care products may be very complex, sometimes containing dozens or even hundreds of different substances, many of which come from plants or other natural sources, which makes it difficult to detect the ingredients.

At present, the standard test method is to evaluate the components of health care products by chromatography. However, for complex products, the information obtained by chromatography is limited. Some new technologies, such as the combination of liquid chromatography and mass spectrometry, and other analysis, can obtain more accurate results. However, before these technologies are widely used, further verification is needed, and the cost must be reduced to be routine.

Drugs for treating diseases are supervised by FDA. Who wants to test the health care products that have been deregulated by the FDA? How credible are the quality inspection data published by the manufacturers themselves? The best way is to be tested by an independent, disinterested third-party organization, so that the data obtained can be convincing.

Figure: Certification marks of three major health care products quality inspection organizations

01

USP certification

You may notice that many health care products in the United States have the words "USP verified" on their bottles (pictured above). This means that the product is certified by an independent, non-profit scientist organization called "USP Dietary Supplements Verification Program". USP sets a quality standard for food ingredients and health care products, and then welcomes manufacturers to cooperate with them voluntarily and let them test their production facilities, processes and product quality. If it meets the standard, the product can bear USP verification mark. The organization also updates the certified brands and where to buy these products on the website in real time [3].

But be careful, some companies will put "USP" on the bottle label instead of the unique black and yellow "USP Verified" seal. These companies claim to meet USP production standards, but in fact their products have not been reviewed by USP. In fact, only a few health care products have "USP Verified" seal, such as some Kirkland brand health care products in Costco.

In addition, strictly speaking, USP can not be regarded as a truly independent third-party testing, which requires the voluntary cooperation of manufacturers.

Figure: USP verification mark on health care products (from the network)

02

national sanitation foundation

Another non-profit organization that independently certifies certain health products is NSF International. This organization will certify health products such as fish oil and multivitamins. In addition, it also has a "NSF Certified for Sport" project, which is particularly useful for athletes and people who use sports supplements (such as protein powder, amino acids and creatine), because it has been found that these products are sometimes intentionally doped with stimulants.

The blue and white NSF logo means that the product has been reviewed by NSF and contains the ingredients listed on its label.

Figure: NSF markers of different species [4].

03

Other test reports

There are also some independent laboratories that regularly test a series of health care products, and then publish their test reports on their websites, such as ConsumerLab.com, labdoor.com, cptclabs.com and so on. On their website, you can find many test reports and rankings of health products, but you usually have to pay to see them.

Figure: Certification mark of Consumer Lab

04

Third-party test plan of CVS in pharmacy

In 2017, CVS, a famous American pharmacy, announced that it had started testing health care products on its shelves, and had completed testing 1,400 health care products from more than 150 suppliers. Early test results show that 7% of the products are not up to standard, and the reasons include pollution, the content of active ingredients is lower than that indicated on the label, and various counterfeiting behaviors. Common fraudulent behaviors are:

1) Substitute cheap compounds for more expensive components.

For example, manufacturers sometimes add a large number of other common flavonoids, such as quercetin or rutin, to a health care product called Ginkgo biloba. These flavonoids can be found in ginkgo biloba, but the concentration is usually very low.

2) Add some prescription drug ingredients to health care products.

For example, viagra is added to some health care products that claim to enhance sexual function.

Figure: CVS’s third-party advertisement for testing the quality of health care products.

Take health care products with caution.

The certification test mentioned above is a reassurance to consumers. However, these tests often only measure a specific batch number of products, and it is still uncertain whether the next batch of products produced by the same manufacturer still meet the standards.

I want to remind everyone that many health care products have complex ingredients. Sometimes it will interact with the therapeutic drugs prescribed by doctors. For example, some health care products may change the activity of some enzymes in the liver, thus affecting the metabolic absorption of prescription drugs. The changed metabolism may increase the concentration of drugs in the blood and cause adverse reactions; Or reduce the drug concentration in the blood, making it ineffective.

A study in 2015 estimated that in the United States, about 23,000 emergency visits each year were adverse events related to dietary supplements [5]. It is best not to eat health care products casually, and should be carefully considered.

On the evening of April 15th, local time, a fire broke out in Notre Dame de Paris, France. This 800-year-old medieval Gothic building immediately attracted the attention of the whole world. At present, the fire has been extinguished. Many French media reported that the short circuit of the wire on the top floor of Notre Dame de Paris may be the cause of the fire, and firefighters involved in the rescue said that the fire may be related to the renovation project of Notre Dame de Paris.

With the decrease in the number of new houses and the gradual improvement of infrastructure construction in China, experts predict that the future construction market pattern in China will gradually transition from the current focus on new buildings to the focus on the renovation and maintenance of existing buildings, and enter the post-construction era. In the impression of many people, the repair of buildings is often associated with ancient buildings. In fact, in the field of construction engineering, repair in a broad sense includes reinforcement, transformation, maintenance, decoration and so on; According to the repair specialty, it mainly includes: structural repair, leakage repair, external insulation repair, decoration repair and so on.

In addition to a wide range of fields, the number of buildings to be repaired is also considerable. The data shows that the existing building area in China is over 70 billion square meters. Due to the different construction technical standards and construction levels in different eras, in recent years, an average of about 2 billion square meters of buildings need to be repaired every year. However, compared with some developed countries, China has little investment in the renovation of existing buildings, and there are some problems, such as imperfect standard system, asymmetric market information, imperfect technical system and lack of long-term management mechanism. Judging from the proportion of market share in the whole construction industry, the construction renovation industry has not yet ushered in a real "spring".

Rising "sunrise industry"

In the past 40 years of reform and opening up, the construction industry, one of the pillar industries of China’s economy, has developed rapidly. According to statistics, the building area in China has increased by 91.4% in the past 20 years, and the existing building area has reached more than 70 billion square meters. With the development of society, the problem of housing shortage has been basically solved. However, in recent years, there are about 2 billion square meters of buildings that need to be repaired every year due to different construction technical standards and construction levels in different eras, so many people in the industry call the building repair industry "sunrise industry".

In July 2018, the insulation layer of the external wall of a residential building in Shunyi District of Beijing fell off due to sudden strong wind, injuring three pedestrians; In October, 2017, a concrete block fell off the outer wall of a residential building in Lishui City, Zhejiang Province, causing one death … Faced with frequent safety accidents, the industry is increasingly hoping to improve the prevention mechanism of existing building repairs to prevent injuries from happening again.

"The development of the construction industry can be divided into three stages: the first stage is large-scale new construction, the second stage is both new construction and repair, and the third stage is mainly the repair of existing buildings." Tan Chunli, director of the Repair and Decoration Professional Committee of Beijing Urban Construction Science and Technology Promotion Association, believes that compared with developed countries, China’s investment in the repair of existing buildings is relatively small, and it is still in the second stage. In the case of shrinking new building market, the building repair industry, which mainly focuses on old buildings, will become a "sunrise industry", and its market share will continue to expand and become a new economic growth point.

"The building repair industry is promising in the future." Yang Yongqi, a professor-level senior engineer of Beijing Urban Construction Science and Technology Promotion Association, believes that upgrading the safety performance of building structures and improving the functionality of houses will make people live more comfortable and comfortable, and building repair is consistent with the current people’s pursuit of a better life.

In September 2018, the Ministry of Housing and Urban-Rural Development issued the "Notice on Further Improving the Preservation, Utilization and Renovation of Existing Buildings in Cities", which also highlighted that the practice of simply demolishing existing buildings in different periods in some cities separated the historical context of cities and cut off the homesickness memories of residents. All localities should fully understand the historical, cultural, technical and artistic value of existing buildings, adhere to the principle of full utilization and functional renewal, strengthen the preservation, utilization and renovation of existing buildings in cities, avoid one-sided emphasis on the value of land development, and prevent "demolition".

However, although the building repair industry has broad prospects, it also faces a lot of challenges for practitioners. He Xiling, president of Beijing Construction Engineering Quality Inspection and Housing Construction Safety Appraisal Industry Association, believes that there are great differences between new projects and the repair of existing buildings, which puts forward many new requirements for the industry. "Building repair requires experienced technicians, high-tech instruments and equipment, new construction technologies and new building materials."

It is urgent to establish and improve the institutional system.

"Because the country attaches great importance to ancient buildings and has a long development time, the standards for the repair of ancient buildings are relatively sound and the atlas is relatively standardized, and the local standards in areas with large stocks of ancient buildings are also easy to form a system. However, the repair atlas of houses mainly focuses on seismic reinforcement and structural reinforcement, and there are relatively few dedicated to waterproof and thermal insulation; In terms of standards, the relevant system has not yet been established, and some important standards have been around for a long time, such as the "National Unified Housing Repair Project Budget Quota (Civil Engineering, Ancient Buildings, HVAC, Electrical Appliances, Elevator)" promulgated in 1995. " Tan Chunli said.

In addition to the imperfect standards, there are still some problems in the market, technology and management of the building repair industry. At the market level, Tan Chunli believes that there are mainly problems such as information asymmetry. "At present, the repair market is in a decentralized and disorderly state, lacking an open and transparent platform, and the supply and demand sides can’t get effective contact in the repair market, and often there is a phenomenon of’ no one to seek medical treatment’ or’ going to the doctor in a hurry’. In addition, the industrial chain of the repair market is still not perfect, and the scale of repair enterprises is generally small, which cannot provide one-stop professional services from testing, maintenance to maintenance for building users. "

On the technical level, compared with new projects, repair projects involve many technical requirements and require a large number of professional construction technicians. "Professional construction technicians are the foundation for the development and growth of the repair industry. Only a large-scale professional construction team can support the complicated repair requirements of the repair industry." Tan Chunli believes that at present, experts in the repair industry have no smooth channels for suggestions and suggestions, and they can’t play a leading role in the development of the industry. At the same time, construction workers who lack technology can’t get effective training. In addition, the current repair technology is single, the technical level is uneven, and the technical system construction is relatively backward. Once there is a problem in the building, we can only treat the headache and the foot pain, but we can’t comprehensively and accurately evaluate the building to be repaired, and we can’t confirm the effect after the repair.

At the management level, there is a dead end in the supervision of building repair, and there are irregularities such as technical appraisal and acceptance, and the market is full of new materials and concepts, which makes it difficult for ordinary consumers to judge. In addition, a long-term management mechanism needs to be established. At present, there is a general lack of a unified management system for repair funds, reporting procedures, bidding, and especially the implementation of renovation.

With the continuous application of new technologies such as UAV reconnaissance, 3D printing and BIM in building repair, how to better develop the building repair industry in the direction of standardization, specialization and quality has attracted the attention and thinking of many people in the industry. To this end, 10 units including Beijing Urban Construction Science and Technology Promotion Association, Tsinghua University, Beijing Jiaotong University and Beijing Jianzhu University recently initiated the establishment of "Beijing Urban Construction Science and Technology Promotion Association Repair Hospital", hoping to play a better role in information, technology and platform, and promote the development of building repair industry.

According to Tan Chunli, who was elected as the president of the Repair Hospital, the purpose of the establishment of the Repair Hospital is to gather more industry experts, integrate repair resources, help solve the problem of "difficult to see a doctor" in the repair market, and provide all-round guarantee services during the whole life cycle of the building, including daily physical examination of the building, consultation of the building to be repaired, provision of professional "treatment team", supervision and acceptance of "treatment effect"

　　Xinhua News Agency, Changchun, August 1st. Title: A 70-year-old man with 109 heroes monuments.

　　Xinhua News Agency reporter Jin Jinxiu

　　"I want to leave a place for future generations to commemorate the martyrs and let the heroic stories be passed down from generation to generation … …”

　　In Wangqing County, Yanbian Korean Autonomous Prefecture, Jilin Province, there is such a 70-year-old man who persisted for 16 years and rushed to build 109 monuments for the martyrs who sacrificed in this revolutionary land.

　　"Jindalai in the mountains, the monument to the martyrs in every village", now more red seeds take root and sprout at the foot of Changbai Mountain, just like Jindalai flowers all over the mountains, red and hot.

　　Monument repairer in revolutionary land

　　["Compared with the martyrs, what is this hard work!" 】

　　The 74-year-old Jin Chunxie is now the director of Wangqing County Committee for the Care of the Next Generation. In 2005, Jin Chunxie retired and did not enjoy the leisure time after retirement. He took the initiative to set up a monument for the anti-Japanese heroes for more than ten years.

　　He can’t forget the scene when he first saw the grave of Tong Changrong, secretary of the CPC East Manchu Special Committee in 2005 — — In the dense forest, small earthen bags less than one meter high are only surrounded by small stones, covered with weeds, and only one’re used for identification. "Tong Changrong went to the Northeast to resist Japan. He died heroically at the age of 27, but he didn’t even have a decent tombstone." Jin Chunxie couldn’t help crying.

　　According to historical records, during the Anti-Japanese War, there were 105 battles in Wang Qing, including 177 tombs of anti-Japanese martyrs and anti-Japanese joint sites, where more than 600 anti-Japanese soldiers were buried. Jin Chunxie found that many young people did not understand this history and could not name the martyrs. So he made up his mind to build a monument for the martyrs, "not to let history break in our generation."

　　I heard that it was a monument to the martyrs, and everyone stepped in to support it. Jin Chunxie often bows and thanks: "I thank you for more than 600 martyrs who died in this hot land!"

　　Jin Chunxie is communicating with the families of several martyrs (photo taken on August 12, 2015). Xinhua News Agency reporter Xu Changshe

　　In order to save money, from design to construction, Jin Chunxie personally went into battle, "rubbed" on various engineering vehicles to and from the construction site, and ran more than a hundred times in quarries hundreds of kilometers away. In 2010, Jin Chunxie was infected with hepatitis C, and the side effects of drugs made him sleepless, itchy all over, losing a lot of hair and losing more than 20 kilograms. Even so, he refused to delay the construction period. People around you said they didn’t understand: why did you toss about when you could have spent your old age safely?

　　"Compared with the martyrs who gave their lives, what is my hard work!" Jin Chunxie replied like this.

　　A narrator of heroic stories.

　　[A person "red" a city]

　　In 2011, Tong Changrong Martyrs Cemetery was completed. Driven by Jin Chunxie, the local government accelerated the construction of martyrs’ monuments and anti-Japanese sites. In the past ten years, 109 monuments have been erected on this land that was once stained with the blood of martyrs. And Jin Chunxie has more plans — — Write books and biographies for the anti-Japanese soldiers, and leave the heroic deeds of the heroes and heroes that make people cry for future generations.

　　"Jin Dage gets up at 4 am every day and starts to work. Over the years, he has traveled to more than ten provinces and cities to collect historical materials." Lang Lianfu runs a local iron art company. In 2018, Jin Chunxie found him and mobilized him to create a red picture book together. Lang Lianfu picked up his "old job" and completed four comic books with three other art teachers, all of which were donated to the society for free. "Encouraged by Jin Dage, the more we work, the more energetic we are!" He said.

　　Compile more than 1 million words of historical materials, draw a picture book of the Anti-Japanese War, and shoot a biographical film of heroes and heroes … … Jin Chunxie went around looking for anti-Japanese war veterans and descendants of martyrs, walked more than 20 thousand kilometers and wore out more than a dozen pairs of rubber shoes. Jiao Chunmei, deputy director of the training department of Wangqing Patriotism Education Center, said that at first, volunteers were only old comrades of the Committee, and now three generations from all walks of life have joined, and the team has been growing.

　　In 2015, Jin Chunxie was rated as the national "model of the times"; In 2019, it was selected as "the most beautiful struggler"; In 2021, he was awarded the title of "National Excellent Communist party member" … … Jin Chunxie’s persistence caused strong repercussions in the local area. With the support of the local Party committee and government, Wang Qing excavated red resources, built a patriotic education base and developed a series of red tourist routes, which attracted a large number of tourists from inside and outside the province.

　　"Old Jin Chunxiao is alone ‘ Red ’ A city. " Xu Hailan, member of the Standing Committee of Wangqing County Committee and deputy magistrate, said.

　　["Let the red gene continue from generation to generation"]

　　"In 1932, Tong Changrong led the special committee to move from Wangyugou in Yanji County to Macun … …” Before and after July 1st, there was an endless stream of tourists visiting the ruins of Xiaowangqing’s anti-Japanese guerrilla base. At the scene, the 11-and 12-year-old lecturers told the story affectionately, and people gave thumbs up one after another.

　　They come from more than 1,400 young commentators trained locally. For more than a decade, Jin Chunxie has lectured on nearly 100 patriotic education classes in various places and held 21 photo exhibitions on patriotic education for young people.

　　Inspired by Jin Chunxie’s red education, in 2010, the fourth primary school in Wangqing County established the first "Tong Changrong Hero Squadron" in Wangqing County. In 2017, with the approval of the National Red Army Primary School Construction Engineering Council, the school was renamed as "Chinese Red Army of Workers and Peasants Jilin Wangqing Tong Changrong Red Army Primary School". At present, 42 primary and secondary schools in the county have set up heroic squadrons (classes) to carry out revolutionary traditional education.

　　At the beginning of this year, Huang Ruiqi, an art teacher of Luozigou Town Central Primary School in Wangqing County, who was born in the 1990s, joined the volunteer team and participated in many thematic art exhibitions such as anti-union and anti-epidemic. Recently, she grabbed her spare time to create oil paintings, showing the hardships of martyrs climbing the ice and lying in the snow, and praising the great rivers and mountains of the motherland. "Grandpa Jin Chunxie took us into history and let the younger generation understand that a happy life should be cherished and the red spirit should be passed on." Huang Ruiqi said.

　　Compilation of Memorabilia in the History of the East Manchuria Anti-Japanese War, and revision of the new edition of "The Fallen Remains" … … Talking about this year’s work plan, the 70-year-old man is hale and hearty. In order to collect historical materials and better spread Wang Qing’s red story, he not only learned to type with a computer, but also went into the live broadcast room to record a short video.

　　"Let the red gene continue from generation to generation." Jin Chunxie said.

　　Recently, the news of sudden death of female college students in Shanxi University of Finance and Economics caused concern.

　　Figure Self-boiling video

　　On March 27, Shanxi University of Finance and Economics issued a briefing on this matter, mentioning that in the group jogging, the classmate suddenly fell to the ground after jogging for about 200 meters. Unfortunately, after a series of rescues, life was still not saved.

　　Sports sudden death is mostly cardiogenic!

　　In recent years, some of the news about young people’s sudden death occurred at work, and some occurred during marathon, fitness, running and other sports.

　　"The main cause of sudden death from exercise is sudden cardiac death (81%), most of which is caused by potential heart diseases. Brain-derived sudden death accounted for the second cause of sudden sports death (17%), mainly including cerebrovascular malformation, aneurysm or hypertension. " Chen Luyuan, chief physician of the Department of Cardiology, Guangdong Provincial People’s Hospital, pointed out in an interview with the Health Times reporter in 2019. ①

　　Zhang Daimin, deputy chief physician of the Department of Cardiology, Yifu Hospital affiliated to Nanjing Medical University, said in an interview with Zi Niu News in 2022 that sudden death during exercise is mostly caused by the rupture of some plaques of blood vessels, resulting in myocardial ischemia and myocardial infarction. Especially when you are in a state of fatigue for a long time, the probability of this situation will be higher. There are three main reasons:

　　First of all, after a long period of fatigue, the body’s immune system function declines, and the whole body will be in a more fragile state;

　　Secondly, after a long period of fatigue, combined with the increase of blood pressure, blood lipid or blood sugar, these factors will induce the rupture of vascular plaque;

　　Third, under the stress state such as exercise, the factors of vasoconstriction increase, which also increases the probability of vascular plaque rupture. Many unfavorable factors are concentrated in fitness under long-term fatigue, which is very prone to some cardiovascular diseases. ②

　　There is a "black triangle" for sudden death, so don’t put it together!

　　Guo Jihong, chief physician of Cardiovascular Department of Peking University People’s Hospital, said in the Health Times article in 2013 that sudden death has a "black triangle", and sudden death can occur when one of these three corners appears, and the probability of sudden death is higher in two places and more dangerous in three places.

　　1) The lower corner has had cardiovascular diseases, such as myocardial infarction, cardiomyopathy and heart failure;

　　2) In the other corner below, there was an abnormality in ECG;

　　3) The apex is internal environment instability, autonomic nerve instability, sympathetic nerve excitement, electrolyte disorder, etc.

　　The bottom two can still be checked out, but the top one is "unstable internal environment" and emotional instability. Excitement, anger and fatigue are often inducing factors, so you should pay more attention to it at ordinary times. ③

　　We should know that long-term stress, hostility, smoking, lack of sleep, unhealthy diet, lack of physical activity and so on will increase the excitement of sympathetic nerves. ④

　　People who are in good health and have no physical examination problems may have sudden cardiac death when they are in a state of high fatigue and high tension. In an interview with Health Times in 2019, Xu Zhimin, deputy chief physician of the Department of Cardiovascular Medicine of Xinhua Hospital affiliated to Shanghai Jiaotong University School of Medicine, reminded the majority of young people that they should learn to pay attention to their physical condition, adjust their emotions in time, and avoid excessive tension and fatigue, especially not to engage in tiring behavior or work at night. ①

　　Stay away from sudden death and do these 5 points at ordinary times!

　　1. To know your heart health, physical examination is very important.

　　You can set up a heart health file for yourself. Middle-aged people, in particular, should have an "annual inspection" of cardiovascular system. In addition to electrocardiogram, dynamic electrocardiogram examination, color Doppler echocardiography and exercise electrocardiogram can help to find myocardial ischemia, arrhythmia, abnormal heart structure, evaluate heart function and help to find coronary heart disease early. Of course, it’s up to the doctor to decide what specific tests need to be done. ⑤

　　2. Identifying sudden death signals is not untraceable.

　　Chen Luyuan, chief physician of the Department of Cardiology, Guangdong Provincial People’s Hospital, pointed out in an interview with the Health Times reporter in 2019 that most of them had clinical symptoms a few days before sudden death. For example: transient chest tightness, chest pain, fatigue and palpitation. This kind of palpitation is a sudden sinking of the body, or a feeling of flickering. The time is about three or five minutes, which quickly passes and naturally returns to normal. Especially unexplained syncope, such as dyspnea, irritability, sweating, abnormal snoring, etc. In this week or so, it is possible that the above situation will happen. ①

　　Don’t stay up late, make sure you get enough sleep.

　　In healthy young people, if they lack sleep for a long time and suddenly engage in high-intensity exercise, they may increase the risk of acute cardiac stress and heart disease.

　　Ruan Xiaoyun, the pharmacist in charge of the Pharmacy Department of central hospital of wuhan, said in the Health Times article in 2016 that staying up late often will make people’s sympathetic nerves and parasympathetic nerves in a state of dysfunction, which will increase the incidence of cardiovascular and cerebrovascular diseases, especially for some people who have no symptoms at ordinary times but have high work pressure and unhealthy lifestyle, which leads to low resistance. Under the stimulation of high temperature, it is more likely to cause arrhythmia and promote lack of blood circulation. Once the blood supply to the brain is insufficient, it will lead to hypoxia, so it will suddenly syncope, which is triggered. 　⑥

　　Don’t be too tired, learn to relax yourself when you are stressed.

　　First, don’t make yourself too tired in work and study. Be sure to leave time for relaxation and don’t sit for a long time. According to the report on the health effects of overwork published in Environment International in 2021, compared with the standard working hours of 35-40 hours per week, people who work 55 hours or more per week have a higher risk of ischemic heart disease and stroke. Undoubtedly increased the risk of sudden death. ⑦

　　二是，放松休息不一定就是睡眠，比如看书、唱歌、散步、练习毛笔字，让自己觉得开心、身心放松的小事都可以多做一做。偶尔近期较忙导致睡眠时间过少，也不等于大脑就没休息，学会自我放松，让自己的身心得到充分的休息，比睡着没睡着更为重要。⑧

　　5.　运动要规律且适量，别透支身体

　　长期习惯性、规律性的运动，是可以降低运动相关心脏骤停风险的。但是，也要注意2点：

　　1）不管是普通人还是运动员的训练，都要讲求一个“度”字，不要轻易超越上限。尤其是未经系统训练和平时体质较差的人群，过大运动量加重心脏负担。一般强度以微微出汗，第二天不累为宜。

　　2）如果是过度疲劳状态的话，继续运动也会继续透支身体，诱发一些心血管疾病的发生。所以疲劳状态就不要大量运动了。

Malignant tumor, commonly known as cancer, is a fearsome disease. Its rapid development and potential lethality always affect the hearts of the public.

Cancer is not a single disease, but a variety of diseases that occur in various organs and tissues of the human body. With the change of lifestyle and environment, the incidence of cancer is increasing year by year. We need to have a deep understanding of its early symptoms and take health precautions.

The formation of malignant tumor is just like the rebellious cells in the body, which proliferate and divide out of control and form a mass that harms the body.

These tumor cells can erode the surrounding tissues and organs, and spread to other parts of the body through the blood or lymphatic system, forming so-called distant metastasis. When malignant tumors appear, they will show the following symptoms:

People with malignant tumors in the body generally have seven manifestations, so pay attention to observation.

1, continuous fatigue and fatigue

Cancer-related fatigue is essentially different from daily fatigue, but it is painful. This kind of fatigue feeling is like a heavy stone, which brings a heavy burden to patients’ physical and mental health.

The patient’s energetic body makes him exhausted, and the persistent fatigue caused by cancer is a complex phenomenon woven by multiple factors.

First of all, the rapid proliferation of cancer cells makes the energy metabolism in the body like a mess, and the "fuel station" that originally provided energy for the body becomes disordered, which makes the energy consumed by the patient’s body increase continuously.

On the other hand, cancer patients are often accompanied by chronic inflammation, which, like an untimely bomb, may trigger an alarm at any time.

The continuous activation of the body’s anti-inflammatory system consumes a lot of body energy until it finally runs out of all energy. To sum up, cancer-related fatigue is stubborn, which weighs on the body and mind of cancer patients and greatly reduces their quality of life.

Therefore, we need to understand it deeply and find effective coping strategies to help cancer patients alleviate their pain and improve their quality of life.

2, itching all over the body

Cancer cells are like a group of uninvited guests. After they break into our bodies, they will release some inflammatory factors and itching mediators. The "gifts" of these uninvited guests not only make people feel uncomfortable, but also stimulate our skin and cause abnormal skin itching symptoms. This itching symptom is like a "storm" on the skin, which makes patients feel unbearable.

3. emaciation

The appearance of cancer cells, like a black hole in the body, constantly devours normal cells and competes for the nutrition of the body. Subsequently, the health of the body goes from bad to worse, just like autumn leaves that are gradually dying, and gradually become thin and fragile.

4. Changes in defecation habits

When suffering from intestinal cancer, patients’ defecation habits often change uncomfortably. They may defecate once a day, and suddenly become several times a day, or even as many as 3-4 times.

However, some patients may experience painful constipation or bloody excrement when defecating. These symptoms can’t help but remind people of sad pictures, but they are the real pain and suffering experienced by patients with intestinal cancer.

5, persistent cough, dysphagia

Thyroid cancer, esophageal cancer, lung cancer and other lesions, once they invade the recurrent laryngeal nerve, will lead to cough, dysphagia and other adverse symptoms.

These symptoms are similar to a cold at the beginning, which often misleads our judgment. However, once the course of the disease exceeds 1-2 months, the tone suddenly changes, coughing continuously or blood in the sputum may reveal the excessive proliferation of tumor cells and have invaded the mouth and throat.

At this time, we must be alert and go to the hospital for detailed examination in time to avoid the deterioration of the condition.

6. Symptoms of growing lumps or lumps

In daily life, the early warning of tumors is often hard and swollen substances in some parts of the body, such as armpits and breasts, which are hard and difficult to dissipate.

When these strange phenomena appear in the body, it is likely that tumor jun has quietly arrived. Therefore, it is wise to do medical examination in time.

7. hoarseness

Abnormal hoarseness requires high vigilance, which may be caused by throat tumor, especially with dysphagia and cough symptoms.

How to prevent cancer?

Cancer prevention is an important public health task, because cancer has a far-reaching impact on individuals and society. To prevent cancer, we need to take various measures, including improving living habits, adjusting diet, strengthening physical exercise, controlling weight, avoiding smoking and limiting alcohol intake.

First of all, improving living habits is the key to preventing cancer. Keeping enough sleep, reducing stress, insisting on proper exercise and avoiding sedentary behavior are all important living habits. These measures help to maintain good health, prevent obesity and strengthen the immune system, thus reducing the risk of cancer.

Secondly, diet also plays an important role in preventing cancer. We should avoid high-calorie and high-fat foods and control the intake of sugar and salt. On the contrary, you should eat more foods rich in fiber, vitamins and minerals, such as vegetables, fruits, whole grains and lean meat. In addition, some studies show that moderate consumption of nuts and olive oil can reduce the risk of certain cancers.

Physical exercise is also one of the important measures to prevent cancer. Proper exercise can help people maintain a healthy weight, enhance the immune system and metabolic rate, thus reducing the risk of cancer. It is recommended to do at least 150 minutes of aerobic exercise every week, such as brisk walking, running and swimming.

Weight control is also one of the important measures to prevent cancer. Obesity has been proved to be associated with many cancers, such as breast cancer, colon cancer and kidney cancer. Therefore, maintaining a proper weight can reduce the risk of these cancers.

Finally, avoid smoking and limit alcohol intake. Smoking is the main cause of lung cancer, while alcohol intake is related to oral cancer, laryngeal cancer and liver cancer.

By avoiding these bad habits, the risk of these cancers can be reduced. To sum up, various measures are needed to prevent cancer, including improving living habits, adjusting diet, strengthening physical exercise, controlling weight, avoiding smoking and limiting alcohol intake.

These measures can not only help people reduce the risk of cancer, but also help to maintain their health and promote the overall health level.

In the first three quarters, China’s consumer market accelerated its recovery. Among them, the total retail sales of social consumer goods increased by 6.8% year-on-year, the retail sales of services increased by 18.9%, and the contribution rate of final consumption expenditure to economic growth was 83.2%.

Sheng Laiyun, deputy director of the National Bureau of Statistics, said that under the influence of a series of policies to promote consumption, China’s consumption, especially service consumption, showed a good trend of rebound and recovery.

The market is recovering well.

In order to promote the sustained recovery of the consumer market, since the beginning of this year, a series of policies and measures to promote consumption have been introduced from the central government to the local government, covering many fields such as automobiles and home furnishing.

"As the effect of the policy’ combination boxing’ continues to emerge, the consumption of residents has improved, especially the consumption of some bulk commodities has improved significantly." Zou Xianyu, deputy director of the Macro Department of the Economic Forecasting Department of the National Information Center, said that from the overall trend, the cumulative growth rate of total retail sales of consumer goods in the first three quarters reached 6.8%, a significant increase of 6.1 percentage points over the same period of last year. In September, the total retail sales of social consumer goods increased by 5.5% year-on-year, 0.9 percentage points faster than last month, among which urban consumption accelerated by 1 percentage point in September, and the improvement trend of consumption growth momentum was further revealed.

The recovery growth of domestic demand has played an important role in the stabilization and recovery of China’s economy. In terms of classification, residents’ consumption expenditure has accelerated, service consumption such as catering and accommodation has grown rapidly, and consumption of bulk commodities such as automobiles has grown steadily, and the potential of the domestic big market is constantly being released.

Service consumption is a bright spot. Since the economic operation has returned to normal, the offline passenger flow has gradually picked up, driving the service consumption to recover quickly. The data shows that the year-on-year growth rate of service retail sales in the first three quarters was significantly higher than the growth rate of total retail sales of consumer goods. Xia Jiechang, vice president of the Institute of Finance and Economics of China Academy of Social Sciences, believes that in the consumer market, the development potential of service consumption is the most worthy of attention. Service retail not only has the general function of retail circulation activities, but also shows important driving effects in supply upgrading, consumption expansion, industry innovation and social employment, and is expected to become the new engine of China’s economic growth in the future.

This year’s Mid-Autumn Festival and National Day holidays, whether it is the number of trips, tourism consumption or accommodation, catering income data, have maintained a strong growth momentum. "This shows that the market activity has increased and it also highlights the potential and vitality of market consumption." Sheng Laiyun said.

While offline passenger traffic gradually picked up, online retail also maintained rapid growth. In the first three quarters, the national online retail sales reached 10.8 trillion yuan, an increase of 11.6%, which was 4.8 percentage points higher than the growth rate of the total retail sales of social consumer goods, and the contribution rate of physical network zero to social zero growth reached 33.9%. Among them, new formats such as live e-commerce are developing strongly. According to the latest data from the Ministry of Commerce, in the first three quarters, 151 of the 170 national e-commerce demonstration bases established live broadcast bases, and the national live broadcast e-commerce sales reached 1.98 trillion yuan, up 60.6%, accounting for 18.3% of the online retail sales. The live broadcast e-commerce pulled the net to zero growth rate of 7.7 percentage points.

Consumption potential needs to be tapped

Although the consumer market continues to recover steadily, the internal and external environment facing steady growth is still severe and complicated, and the consumption potential needs to be further tapped.

Taking new energy vehicles as an example, the sales of new energy vehicles accounted for 29.8% of the total sales of new vehicles in the first three quarters, and the supporting charging infrastructure system was also continuously optimized. However, there are still some problems in rural areas, such as insufficient construction of public charging infrastructure, difficult installation and sharing of charging facilities in residential communities, and prominent contradiction between supply and demand in different periods, which restrict the release of consumption potential of new energy vehicles in rural areas. In the next step, we should effectively reduce the restrictions on the installation of charging piles in rural power grids, promote the popularization of rural charging facilities, and fill in the shortcomings of consumer infrastructure.

In addition, it is necessary to strengthen the digital empowerment of traditional business districts and further promote the continuous improvement of physical store operations. Zou Xianyu said that in the process of focusing on supporting the construction of digital commercial blocks, it is necessary to support new business layouts such as smart retail, cross-border retail and unmanned supermarkets.

"China’s consumption potential is relatively large, and its population size is relatively large. In addition, it is at a critical stage of upgrading its consumption structure. As the economy continues to recover, the overall consumption trend in China will be good." Sheng Laiyun said that in the fourth quarter, China’s consumption will continue to recover in the first three quarters.

"Starting from the overall strategic situation, the state attaches great importance to expanding domestic demand in steady growth, gives priority to restoring and expanding consumption, and has launched a series of policy’ combination boxing’ to promote consumption." Wei Wang, a second-level researcher at the Institute of Market Economy of the State Council Development Research Center, said.

At the same time, the overall employment situation has improved, and the income level has increased steadily, helping the consumption power to stabilize. In the first three quarters, the national per capita disposable income actually increased by 5.9%, 0.1 percentage point faster than that in the first half of the year, which laid a good foundation for the sustainable recovery and growth of consumption in the future.

"Although the current economy is in the process of wave recovery and tortuous progress, with the continuous repair of the balance sheets of enterprises and residents, consumption willingness and consumption power are expected to further recover, and consumption momentum will be further enhanced." Zou Xianyu said that at the same time, we should also see that there is still a distance from the complete recovery of consumption, and the fluctuation of consumption growth is still large. From the perspective of key categories, the gap-filling effect of service consumption will end, and the whole will gradually return to the normal growth trend, and commodity consumption will maintain a moderate growth.

Experts said that the current demand growth rate is still insufficient, and it is necessary to continuously enhance the confidence of enterprises and markets. At the same time, firmly grasp the key link of expanding domestic demand, accelerate the activation of the domestic market, and fully release the economic growth potential of China.
