[Technology] Cars have become an indispensable part of our lives. The combination of steering wheel+shift lever+pedal seems to have become a natural way to control cars, but their respective mechanisms are rarely understood. Take the steering wheel in our hands as an example, the majority of riders are still vague about the common concepts of various steering systems, such as "the difference with hydraulic power" and "what is the variable power", and so on. Below, we will systematically introduce various common steering systems, answer these questions, and discuss the mysteries and mysteries of various steering systems with you.

　　Because of the long space, this paper introduces our most common system now, interprets "where does the power come from" and introduces the classification of power steering system.

　　Power steering, as its name implies, is to resist steering resistance by increasing external force, so that drivers can complete steering with less force. It is also called power steering. It was originally designed to make some large vehicles with heavy weight operate more easily, but now it has become very popular. It makes driving easier and easier, and makes vehicles more agile and improves safety to some extent. Power steering can be divided into two categories according to the different sources of power-hydraulic power and electric power.

●

　　The origin of hydraulic power steering can be traced back to February, 1902. Frederick W. Lanchester of Britain invented "Cause the steering mechanism to be actuated by hydraulic power", that is, the hydraulic driving steering mechanism. After that, inventors in the United States and Canada successively registered patents for similar inventions. In automobile production, the commercial production of hydraulic power steering system was first realized, and it was named Hydraguide hydraulic steering system, and it was installed on Chrysler’s sixth generation Imperial in 1951. With the development of technology, the steering system with electronic pump instead of mechanical pump appears, so the current hydraulic power is mainly divided into mechanical hydraulic power and electronic hydraulic power. In addition, the electronic servo hydraulic power steering system is derived from the mechanical hydraulic power.

　　Let’s look at the main principle of mechanical hydraulic power steering, which is based on mechanical rack-and-pinion steering mechanism, and adds a whole set of hydraulic system, including liquid storage tank, hydraulic booster pump, mechanical valve connected with steering column, hydraulic cylinder on steering mechanism and the one that can push steering rod, etc.

　　The hydraulic pump provided by mechanical power steering is driven by a belt, which means that the steering pump can only run when the engine is running, which is why the steering wheel power disappears after the engine is turned off. On the steering machine, there is a mechanical valve that can rotate with the steering column. When the steering wheel does not rotate left and right, the pressure in the chambers on both sides of the piston is consistent and in a balanced state. When the steering wheel rotates, the mechanical valve connected to the steering column will be opened or closed accordingly, and the oil on one side will return directly to the oil storage tank without passing through the hydraulic cylinder, and the oil on the other side will continue to be injected into the hydraulic cylinder, so that the pressure difference between the two sides of the piston will be pushed under the action of hydraulic force, and then the auxiliary force will be generated to push the steering rod to steer the wheels, which greatly reduces the force required for us to turn the steering wheel.

　　Another advantage of hydraulic power steering system is to improve comfort and safety. When the wheels jump violently and the tires turn involuntarily when encountering potholes, the vibration can be well buffered and absorbed by the action of hydraulic pressure on the piston, which greatly reduces the vibration transmitted to the steering wheel. At the same time, this structure also improves the safety. For example, when a vehicle using the traditional rack-and-pinion mechanism turns, the tire suddenly changes direction when it encounters a pothole, and the rack will drive the gear to reverse the steering wheel, resulting in the situation of "beater", which is easy to hurt the driver’s hand, so there will be no such problem in a hydraulically assisted vehicle.

　　Mechanical hydraulic booster features:The whole system is a mechanical structure, from the mechanical hydraulic pump driven by the belt to the hydraulic mechanical valve body on the steering column, without any electronic system, with mature and stable technology, high reliability and wide application range. Even if the hydraulic system of the vehicle fails and loses power, it can still rely on the traditional rack and pinion mechanism for steering. Disadvantages are complex structure, large space occupation and high manufacturing cost, which also makes the maintenance difficult and costly. And because the hydraulic pump is driven by the engine belt, it will consume part of the power of the engine, which will affect the fuel economy and the power of the vehicle, especially for small-displacement vehicles with relatively weak power. In addition, the strength of the mechanical hydraulic power-assisted system is not adjustable, so it is difficult to take into account the different requirements for pointing accuracy when driving at low speed and high speed.

● Electro-hydraulic booster

　　The so-called Electro-hydraulic power steering (EHPS for short) has exactly the same principle as mechanical hydraulic power steering, but the biggest difference from mechanical hydraulic power steering is that instead of using a hydraulic pump driven by an engine through a belt, it is replaced by an electric pump.

　　The advantages of electro-hydraulic power assist are firstly reflected in energy consumption. First, the electronic pump driven by electric energy uses the electric energy output by the generator and the battery, and no longer consumes the power of the engine itself. The start and stop of the electronic pump are all controlled by the electronic system. When it is not steering, the electronic pump is turned off, unlike the mechanical hydraulic power assist pump, which is always linked with the engine, further reducing energy consumption.

　　Secondly, the electronic control unit of the electro-hydraulic power steering system can change the power of steering assistance by processing the information of sensors such as speed sensor, lateral acceleration sensor and steering angle sensor, and changing the flow rate of the electronic pump in real time, that is, the function of variable power assistance with speed. Of course, it is not only the electro-hydraulic power assist that can realize the variable power assist with speed. We will introduce various "variable" power assist steering systems in detail in later articles.

　　Electro-hydraulic power assist has been gradually popularized since the late 1990s, and brands such as,,,,, and have models using electro-hydraulic power assist system. We are familiar with, and other models use such a system.

"Triumph, old models and other models use electro-hydraulic power."

　　Why can’t electro-hydraulic assist replace mechanical hydraulic assist?

　　No matter from the aspects of technology, function or economy, electro-hydraulic power assistance has more advantages than mechanical hydraulic power assistance. However, at present, electro-hydraulic power assistance has not been able to replace mechanical hydraulic power assistance for the following reasons:

　　1. The cost of electro-hydraulic booster is higher. Compared with the mechanical hydraulic power-assisted system, after adding the electronic control system and replacing it with the electronic pump, the manufacturing cost of electronic hydraulic power-assisted system is higher, the technology is more complicated, and the difficulty and cost of maintenance are also increased.

　　2. The reliability is not as good as that of mechanical hydraulic booster. In addition to the failure of steering mechanism and hydraulic mechanism, electro-hydraulic power assist also increases the possibility of electrical system failure, so its reliability is not as good as that of traditional hydraulic power assist system.

　　3. The assistance is limited. Although the use of electronic pump has obvious advantages, it needs to be driven by the electric energy of the generator, and the vehicle-mounted generator itself and the maximum current it can provide are limited, so the power of the electronic pump is also limited, and the load it can carry is also limited. Therefore, at present, most of the models that use electro-hydraulic power are medium-sized vehicles. For vehicles that need greater assistance, the electro-hydraulic assistance system is beyond the reach.

　　4. Evolved mechanical hydraulic booster system. With the development of technology, the variable speed function of electro-hydraulic power-assisted system has been realized on the evolved mechanical hydraulic power-assisted system (using solenoid valve body technology), and even a variable speed ratio system has been derived from the mechanical hydraulic power-assisted steering system, so the mechanical hydraulic power-assisted system with higher reliability and load-bearing capacity is still welcomed by manufacturers.

　　BEIJING, March 1st (Xinhua)-On the 1st, at the press conference on the theme of "Authoritative Department Begins" held by the State Council Office, Jin Zhuanglong, Minister of Industry and Information Technology, said that the Ministry of Industry and Information Technology would anchor the strategic goals of manufacturing power, network power and digital China, take digital technology innovation breakthrough and application expansion as the main direction, and increase the integrated development of informationization and industrialization. Generally speaking, it is mainly in three aspects: one is the network platform, the other is the digital industry, and the other is the integrated development.

　　The first aspect is to solidly promote the construction of network infrastructure. China has built the world’s largest and technologically advanced network infrastructure, with Gigabit access capacity covering all prefecture-level cities. This year, the Ministry of Industry and Information Technology will further implement the construction of Gigabit cities. Not long ago, the Ministry of Industry and Information Technology held a Gigabit City Summit Forum to guide all localities and enterprises to speed up construction investment and accelerate the deep coverage of 5G and Gigabit optical networks. Study and formulate an action plan for the development of computing infrastructure and strengthen the construction of industrial Internet infrastructure.

　　The second aspect is to accelerate the development of the core industries of the digital economy. In 2022, China’s electronic information manufacturing industry achieved an operating income of 15.4 trillion yuan, and the software business income reached 10.8 trillion yuan, which laid a solid industrial and technical foundation for the integrated development of informationization and industrialization. The Ministry of Industry and Information Technology will accelerate the development of emerging digital industries such as artificial intelligence, big data, blockchain, cloud computing and network security, guide and support enterprises to increase investment in research and development, and improve the industrial level of communication equipment, core electronic components and ultra-high definition display. Promote the high-quality development of integrated circuits and industrial software industries. Build characteristic software colleges with high standards and create a number of famous software parks in China.

　　The third aspect is to vigorously promote the digital transformation of manufacturing industry. Study and formulate a roadmap for digital transformation of key industries and cultivate a number of digital transformation benchmarks. Promote the 5G Sailing Action Plan, deepen the integrated application of "5G+ Industrial Internet", promote the popularization and application of industrial Internet to industrial parks, and build a number of 5G fully connected factories. We will implement the smart manufacturing partner program and standard pilot actions, build a number of world-leading smart factories and smart supply chains, and develop new models and formats such as service-oriented manufacturing.

[Editor’s Note] "We should develop traditional Chinese medicine, pay attention to interpreting the principles of traditional Chinese medicine with modern science, and take the road of combining traditional Chinese and western medicine." On May 12th, General Secretary of the Supreme Leader once again asked about Chinese medicine during his inspection tour in Nanyang City, Henan Province, and put forward new and clear requirements for the further development of Chinese medicine.

Inheriting the essence, the development of traditional Chinese medicine can go back to ancient times; The development of traditional Chinese medicine will be clear and turbulent only when it is upright and innovative. Combined with the outstanding performance and experience of Chinese medicine in the treatment of COVID-19 epidemic, many Chinese medicine experts who have participated in the first-line anti-epidemic talk about their experiences, offering suggestions and suggestions for the high-quality development of Chinese medicine and protecting the health of all mankind.

"The future development of Chinese medicine is to be brave and dare to combine with modern science and technology, and to be good at using modern science and technology language to make the oldest theory of Chinese medicine clear and clear, so that Chinese medicine can truly become a world medicine and a medical system that can be used by all countries and ethnic groups." Combined with the treatment of COVID-19 epidemic, Liu Qingquan, president of Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University, said that the integration of traditional Chinese medicine and western medicine is very important for the development of traditional Chinese medicine, and it may form a new medicine in the future. It not only has the traditional theoretical advantages of Chinese medicine classics, but also embodies the connotation of modern science and technology; It is neither classical Chinese medicine nor modern western medicine, but a complete medical system with complementary advantages.

The experience of Chinese and western collaborative treatment lays the foundation for the formation of new medicine.

In the process of fighting against the epidemic in COVID-19, the effective prescription of traditional Chinese medicine-"three drugs and three parties" screened out by clinic has played an important role.

Liu Qingquan, who once served as an expert in Hubei Central Steering Group and deputy head of the national expert group on medical treatment of traditional Chinese medicine, said that "three drugs and three parties" is actually a classic theory of China traditional Chinese medicine, a treatment method based on the experience of traditional Chinese medicine in treating plague for thousands of years, and a model for coping with new diseases.

"Through the analysis of COVID-19’s clinical characteristics, we have formed the idea that we can combine various effective prescriptions to treat, thus forming the basic idea of’ three parties and three drugs’, that is, according to the changes of etiology and different stages of illness, we can adjust and combine to form effective treatment methods. This proves the greatness and correctness of the theory of traditional Chinese medicine and verifies that it conforms to scientific laws. " Liu Qingquan said.

"In the process of using’ three parties and three drugs’ treatment, we have also preliminarily explored and mastered some theoretical data of treating COVID-19 with traditional Chinese medicine. These studies prove that the basis of treating COVID-19 with traditional Chinese medicine is scientifically explained from different aspects, such as the adjustment of immune system and inflammatory system, which are the important pathological links that cause the disease to change, get worse and worse during the onset of COVID-19." Liu Qingquan analysis.

"In terms of coordinated treatment of Chinese and Western medicine, Chinese and Western medicine have their own strengths, and ultimately played a very important role in improving the success rate of severe and critical care and reducing the mortality rate, which proved the internal theoretical basis of coordinated treatment of Chinese and Western medicine and made some necessary preparations for exploring the organic integration of Chinese and Western medicine to form a new medicine." Liu Qingquan pointed out.

Exploration of Traditional Chinese Medicine Shelter Hospital Model of Infectious Diseases Hospital with Integrated Traditional Chinese and Western Medicine

In the process of Chinese medicine participating in Wuhan epidemic prevention and control and clinical treatment, Fangcang Hospital has become a medical pioneering work in a special period.

Liu Qingquan, a former president of Jiangxia Fangcang Hospital, was deeply touched by the experience of Chinese medicine taking over Fangcang Hospital. He said that the establishment of the shelter hospital is a very effective way to deal with sudden large-scale infectious diseases. In the shelter hospital, the treatment of light and ordinary patients with traditional Chinese medicine can effectively speed up the improvement of patients’ condition, reduce the occurrence of severe and critical diseases and reduce the mortality rate. In addition, because the source of infection is cut off in time, the control of virus transmission also plays a very important role.

Liu Qingquan believes that the experience and achievements gained by taking over Fangcang Hospital with traditional Chinese medicine technology to treat light and ordinary patients in COVID-19 have paved the way for the state to support the establishment of infectious disease hospitals and specialized hospitals with integrated traditional Chinese and western medicine. This will enable the future to quickly form a powerful force of combining traditional Chinese and western medicine, whether dealing with common infectious diseases or sudden new infectious diseases.

Increase investment to support the construction of Chinese medicine institutions and Chinese medicine research.

Nowadays, in the treatment of many local epidemics distributed in China, the treatment scheme of traditional Chinese medicine is becoming more and more perfect and mature, and has achieved very good results. The methods of classified treatment and management of traditional Chinese medicine have become more and more popular and have become the consensus of the medical community.

"Compared with this treatment effect, there are too few medical institutions of Chinese medicine, which is a limitation to the role of Chinese medicine and its future development." Liu Qingquan called on the state to increase investment in TCM research and institution building. In dealing with infectious diseases, it is hoped that the state can support the establishment of infectious disease hospitals in mature areas with traditional Chinese medicine or integrated traditional Chinese and western medicine.

Liu Qingquan said that infectious diseases are the public enemy of mankind, regardless of Chinese medicine and western medicine, regardless of population and race. Therefore, I hope that China can make achievements in the construction of infectious disease hospitals with traditional Chinese medicine and integrated traditional Chinese and western medicine, and set an example for promoting the development of China medicine and even the world medicine. I hope that colleagues of Chinese and Western medicine can work together in Qi Xin to seize the opportunity and let the development of traditional Chinese medicine enter a new era.

　　On May 13th, on the first day of Tmall’s pre-emptive purchase of 618 countries, Taobao took the lead in playing the marketing strategy of "Wang Fried"-Kenny Lin, a national artist of "900 million girls’ dream", was officially declared as the brand ambassador of Taobao countries, and magical advertisements were placed in CCTV, online mainstream APP and offline over 50 cities, brainwashing consumers across the country: "Pay close attention to Taobao and receive state subsidies!" The big promotion policy of "national subsidy+Tmall 618 subsidy as low as 50% off" has strongly reached hundreds of millions of consumers.

　　In this year’s 618 event, Taobao also launched the "National Supplement Surprise Coupon" for the first time: users can grab the "National Supplement Surprise Coupon" which was launched for the first time and has the largest overlapping subsidy, and also participate in the interesting interaction of Kenny Lin, the brand ambassador of Taobao National Supplement; At the same time, watch the live broadcast of Kenny Lin on May 19th, and you will have a better chance to win the opportunity of "up to 10,000 yuan for national exemption". This "618" marketing campaign, which is based on policies, with stars as the guide, welfare as the spear and brand as the shield, once again breaks the routine and "updates" new marketing ideas, and also makes Taobao the first entrance for consumers to receive state subsidies.

　　"Hurry up and update" TVC’s magical brushing screen, releasing the whole world and detonating the country’s mind.

　　Consumers are blown in mid-air by strong winds, grabbing mobile phones passing by; The person at the forefront of the team reached out and grabbed Kenny Lin’s skirts, and shouted with joy, "Hurry up and update!"

　　The magic advertisement in just 15 seconds directly visualizes the core idea of Taobao’s national compensation marketing: "People are blown by strong winds" vividly interprets "the wind of Taobao’s national compensation is too strong"; All kinds of home appliances that have been blown away intuitively show the rich categories of Taobao’s national supplement; The action of "Hurry up to update" is a pun, which skillfully connects the homonym of the name of Kenny Lin, the ambassador of Taobao’s national subsidy brand, with "Hurry up to receive the national subsidy from Taobao", and makes a heavy discount of "make up for it, as low as 50% off", which quickly attracts users’ attention and grabs users’ minds.

　　In addition, Taobao also released several other magical TVCs, such as "Catch Kenny Lin in mid-air", "Kenny Lin City Gate Catch New Household Appliances" and "Delivery Master Catch Kenny Lin". Together with Dafeng Creative TVC, it interestingly explained the four core points of this national supplement: supplement and supplement, rich categories, new products and service mentality, which directly highlighted the interesting marketing style of this 618 Taobao.

　　As the ambassador of Taobao’s national subsidy brand, Kenny Lin’s label setting has always been highly consistent with Taobao’s "affordable and interesting" platform image, and its name of "update" has formed a natural memory point with "grasping Taobao’s national subsidy". In addition, the audience flow brought by last year’s hot works such as "The Story of a Rose" and "With the Phoenix" has contributed to the spread of "grasping the update".

　　In order to detonate the communication potential, Taobao released a global bombing combination boxing: CCTV launched to strengthen the credibility of the policy, covering all ages and nationwide markets; Online mainstream apps open screens and information flow advertisements accurately attack young users; The offline 50+ city business circle will be launched to create an immersive "updated" advertising experience.

　　Long-term marketing drives brand value to upgrade, grasps policy dividend and highlights brand responsibility.

　　When the demonic brainwashing "hurry to update" TVC swept the business circle of 50 cities across the country, Taobao’s national compensation marketing offensive became stronger and stronger-on May 19th, Taobao’s national compensation brand ambassador Kenny Lin will conduct a live broadcast. At that time, Kenny Lin will carry out a series of interesting interactions around the national subsidy, and will also give users a bonus of 10,000 yuan, star signatures, 50 rounds of red packets of rain and other super benefits, so as to create a saturated communication of "offline detonation+online fission" and continue to create a 618 marketing fever.

　　Behind the lively entertainment marketing is Taobao’s deep response to the national subsidy policy: whether it is a big promotion discount, extra subsidies for trade-in, more brands and categories, more urban coverage, or the service of subsidizing 10,000 new products, large and small household appliances and home improvement, users can feel the peace of mind of Taobao’s in-depth implementation of the national subsidy policy as long as they log on to Taobao. This kind of play that turns policy potential energy into brand long-term value also adds weight to Taobao’s "good heart" as a user.

　　It is worth noting that this time, Taobao, the national supplement, assembled 100 head brands for the first time to jointly make profits. Under the call of the platform, many brands actively responded to the national subsidy activities, and strongly conveyed the mind of "leading the country to make up for Taobao" by directly benefiting consumers. The collective call of many merchants not only enriched the lineup of activities, but also helped improve Taobao’s national compensation strategy. Especially under the premise that the national subsidy policy has restrictions on each citizen’s eligibility and quota, Taobao, which has gathered the most comprehensive categories, the best subsidies and exclusive service rights, has naturally become the "first entrance" for consumers to choose to receive national subsidies.

　　Just like this magical TVC advertisement, Taobao’s combination of "national dividend+traffic leverage+global communication" has once again "updated" the new example of e-commerce platform 618 marketing.

　　Recently, according to the China Youth Daily, "Ginger Soaks Foot" and "Drinking Tea for Beauty" … … With the increasing pressure of life, not only the post-90s generation who entered the workplace, but also many college students have begun to try various methods of health preservation. Health preservation is no longer the exclusive word of the elderly or middle-aged people, and the young campus groups represented by college students are constantly adjusting their lifestyles and advocating a healthier life and rest. Why are this wave of college students "trapped in health care" and "selling the old"? Many college students said that this is a way of "self-mockery" to fight anxiety and pressure.

　　In many people’s cognition, college students are relaxed and chic, and can have fun relatively freely. But in fact, many college students are very bitter and tired now. It is not unusual to do homework, research and activities in class until early morning or even later.

　　Under such a realistic background, it is not difficult to understand that many college students are "trapped in health preservation". Recently, a "2018 Life Consumption Trend Report" shows that based on the search volume of "Lycium barbarum" on the e-commerce platform of all ages, the proportion of search volume after 1995 increased significantly in September 2017. Honey, Lycium barbarum, whey protein, health tea and enzymes are the health foods that are keen on after 1995.

　　When I was in college, I was also a "busy maniac". I was really working hard. My meals and sleep were irregular, and I also had a tendency to overeat. At that time, I thought I was still young, so I indulged myself too much and was indifferent to some early warning signals of my body. But now, nearly a year after graduation, all kinds of physical and mental discomforts have emerged, and I realize that "karma" has come and I want to "pay my debts". Therefore, now I will also force myself to keep fit, such as drinking more hot water, going to massage, eating more healthy food and running to and from work.

　　The meaning of life is not temporary, but long-term. To quote a very fashionable online buzzword recently, "People who work too hard can’t run far". Who doesn’t want to "run away" on the road of life? So, please do it and cherish it.

　　Of course, it is not enough to rely solely on the self-awakening of young people, but also to exert efforts at the social level. To put it bluntly, in addition to focusing on the "burden reduction" of primary and secondary school students, the social level should also focus on the "burden reduction" of young people represented by college students. There is no denying that the latter should be under pressure and responsible, and strive hard to realize their own value and social value, but all this should not be at the expense of health. It should be a social consensus that only a good body and a healthy lifestyle can create more shocking values.

Guide the relevant units and personnel not to rent or take tourist buses without chartered procedures or incomplete procedures, which have potential safety hazards, and form a good atmosphere for safe driving and safe car use.

The extinction at the end of Permian 252 million years ago caused the extinction of about 81% marine species and 89% terrestrial species. The main reason is believed to be the environmental change caused by large-scale volcanic eruption, but there is still no direct evidence that environmental factors affect terrestrial ecosystems. In cooperation with foreign counterparts, researchers in China discovered the direct evidence that the destruction of the ozone layer led to the extinction of terrestrial life at the end of Permian by studying the changes of "sunscreen" content in fossil pollen grains during this period.

The research results were published online in the internationally renowned journal Science Advances on January 6, 2023.

Volcanic eruption led to mass extinction of land? There was a lack of direct evidence

The extinction event at the end of Permian was the largest extinction event in Phanerozoic. Scientists generally believe that the increase of global greenhouse gases caused by the eruption of Siberian igneous province at the end of Permian, global warming and ocean acidification may be the main causes of this extinction. However, there are still many debates about how these environmental factors affect terrestrial ecosystems.

Some palynologists have found some deformed spores and pollen in the continental Permian-Triassic transition section. It is speculated that these deformed spores or pollen may be caused by the increase of ultraviolet radiation induced by the destruction of the global ozone layer caused by halogen elements ejected from the Siberian igneous province. However, the study of abnormal spores and pollen produced in modern plants shows that the environmental background of these abnormal pollen and spores is very complicated, and drought, air pollution and plant trauma may all induce abnormal spores or pollen to be produced in plants. Therefore, the discovery of a small number of abnormal spores and pollen in the continental Permian-Triassic transition section cannot directly prove that there was an increase in ultraviolet radiation caused by the global ozone hole during the extinction at the end of Permian.

Using the content of "sunscreen" to deduce the intensity of atmospheric ultraviolet radiation

Plants need sunlight for photosynthesis to provide energy for plant growth, but at the same time, it is necessary to avoid the damage of harmful ultraviolet rays in sunlight to genetic information in plants, especially in plant reproductive cells (spores and pollen). In order to adapt to the terrestrial radiation environment, terrestrial plants have evolved some regulatory mechanisms to reduce the damage of ultraviolet rays to plants. In the germ cells of plants, this mechanism is manifested in that there are a large number of compounds-coumaric acid and ferulic acid-in the outer walls of plant spores and pollen, which are very similar in function to "sunscreen cream". These compounds can form resonance-stable phenol free radicals and resist the oxidation caused by ultraviolet rays, thus protecting fragile spores and pollen and providing guarantee for the spread and reproduction of terrestrial plants.

Modern botanists have observed that plants can automatically adjust the content of "sunscreen" on the outer wall of their germ cells according to the surrounding ultraviolet radiation environment, and these "sunscreen" can be stored in the outer wall of inert spores and pollen for a long time. Therefore, in theory, researchers can determine the content of "sunscreen" in these spores and pollen, and deduce the intensity of atmospheric ultraviolet radiation in geological history.

"Sunscreen" is difficult to digest and has low nutrition, or leads to the extinction of insects.

According to Liu Feng, a researcher at Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, the research team quantitatively measured coumaric acid and ferulic acid in 1011 pollen grains from Permian-Triassic transition section in southern Tibet, China. Through the big data analysis of infrared spectra produced by these pollen, the research team found that during the extinction at the end of Permian, the contents of coumaric acid and ferulic acid in the outer wall of pollen in the stratum were significantly higher than those in fossil pollen before and after extinction, which directly proved that there was an increase in global ultraviolet radiation during the extinction at the end of Permian.

The increase of ultraviolet radiation in the air has a far-reaching impact on the whole terrestrial ecosystem. Because ultraviolet rays not only have a strong killing effect on plant germ cells, but also cause damage to plant mesophyll cells. In order to resist the damage of ultraviolet rays to mesophyll cells, plants will synthesize lutein, coumaric acid and ferulic acid in their leaves, which will reduce the synthesis of chlorophyll accordingly, leading to the weakening of photosynthesis of plants, which will further weaken the absorption capacity of plants for greenhouse gases, further aggravating the global greenhouse gas increase caused by volcanic eruption at the end of Permian.

In addition, lutein, coumaric acid and ferulic acid in mesophyll are compounds that are difficult to digest and have low nutritional value for herbivores and insects, so the increase of ultraviolet radiation indirectly affects the terrestrial food chain, which may be the main reason for the extinction of terrestrial herbivores and insects at the end of Permian.

　　On January 17th and 19th, two patients in Xinjiang died after taking Tangzhining Capsule (batch number "081101") labeled "Guangxi Pingnan Pharmaceutical Factory". After investigation, the "Tangzhining Capsule" that caused the patient’s death was a counterfeit drug, and the chemical component "glibenclamide" was illegally added. According to industry analysts, patients with chronic diseases such as diabetes and hypertension are huge, which has become a "gold mine" for many black-hearted drug dealers to make money. Some products advertised as pure Chinese medicine have illegally mixed western medicine ingredients, or added pharmaceutical ingredients to health foods, which is harmful to patients’ health. This has also become a focus of supervision by law enforcement departments in various places, including Guangdong Province.

　　Three chemical components are often illegally added.

　　According to reports, although the current medical level has made rapid progress, there is no major breakthrough in some difficult diseases, such as diabetes, chronic hepatitis, malignant tumors, etc., and neither traditional Chinese medicine nor western medicine can achieve a complete cure. Wei Hua, deputy director of the Department of Endocrinology, Guangdong Provincial Hospital of Traditional Chinese Medicine, said that as far as Chinese medicine is concerned, its composition is complex and its effect is mild and slow, while western medicine has continuously developed some chemical drugs which are more effective, but its side effects are relatively large. In this regard, some lawless people, taking advantage of the psychological trust of patients in traditional Chinese medicine, promote so-called pure Chinese medicine and health food, and secretly add western medicine chemical components to them, so that patients feel obvious curative effect after taking it, thus increasing sales. For example, the "Tangzhining Capsule" that went wrong this time is under the banner of Chinese patent medicine.

　　Wei Hua said that in addition to the glibenclamide added in the "Tangzhining Capsule" that went wrong this time, gliclazide and glipizide are the most commonly added hypoglycemic western medicine ingredients in those illegal products. According to the relevant regulations, chemical substances are not allowed to be added to traditional Chinese medicine. "Glibenclamide" has a strong hypoglycemic effect, and its pharmacological function is to promote insulin secretion and improve human insulin deficiency through metabolism after entering the blood. However, serious overdose may cause shock and even death.

　　It is understood that the Xinjiang Uygur Autonomous Region Institute for Drug Inspection found that the drugs taken by the deceased during his lifetime contained about 10.33 mg of "glibenclamide" per pill. "Glibenclamide" is a second-generation sulfonylurea, which has a strong hypoglycemic effect, but adults should not take more than l5 mg per day, otherwise it will endanger the life safety of users. According to the instructions of the seized drugs, the normal dosage is 9 capsules per day, which has exceeded the maximum daily dosage by 6 times.

　　You can’t add western medicine to Chinese medicine at random.

　　A person in charge of a pharmaceutical factory told reporters that the incident was not accidental, and illegal drugs, health foods, western medicines and illegal propaganda occurred from time to time. According to National Medical Products Administration, they found that it is not uncommon to add sildenafil, a component of Viagra, to the "pure Chinese medicine" for treating male sexual dysfunction, and to add thyroid hormone to diet food, which can cause hyperthyroidism, so that patients who don’t know the truth suffer from side effects of drugs for no reason. This exposes a problem: most Chinese people believe that "natural drugs" have the advantages of low toxicity and side effects, and it is inevitable that they are not alert to side effects such as dependence.

　　Wang Dahong, Secretary-General of the Market Working Committee of China Health Food Association, said that illegal addition of western medicine ingredients in traditional Chinese medicine or chemical ingredients in health food will do great harm to patients and should not be added indiscriminately. Doctors and patients use mixed Chinese and western medicines without knowing it, which can easily lead to repeated adverse drug reactions. For example, if diabetic patients don’t know that the Chinese patent medicine for lowering blood sugar is added with glibenclamide, they mistakenly think it is a "Chinese medicine with no toxic and side effects" and take it in excess, or take the western medicine for lowering blood sugar at the same time for "integrated Chinese and western medicine treatment", which will lead to overdose of hypoglycemic drugs and hypoglycemia, and even lead to blood sugar fluctuation of patients if they stop taking the medicine suddenly. Therefore, Wang Dahong said that the timely discovery and investigation of the problem "Tangzhining Capsule" has eliminated another safety hazard that harms consumers’ health, and the industry has been further eliminated.

　　Illegal addition has four characteristics.

　　Most Chinese patent medicines or health foods illegally added with western medicine ingredients have the following characteristics: First, they claim that they can cure or greatly improve certain diseases in a short period of time, and their efficacy is remarkable. Second, most drugs are sold through online advertisements, mail advertisements or health knowledge lectures. Third, most drugs or health care products are covered with legal coats. Some products are pure Chinese medicine ingredients when applying for batch number, but western medicine ingredients are added during production. Fourth, the means of addition is very secret. Knowing that the routine drug testing only examines the internal substances of drugs, criminals add western medicine ingredients to the external carriers of drugs such as capsule shell. Finally, it is suggested that consumers can check the authenticity of drugs through the official website of the State Food and Drug Administration.

It is an islet hormone and a drug that affect blood sugar, and can be used to treat mild and moderate non-insulin-dependent diabetes mellitus with unsatisfactory therapeutic effect only by diet control, but the patient’s islet β cells need to have certain insulin secretion function without serious complications, such as diarrhea, nausea, headache, stomachache, liver function damage, thrombocytopenia and other adverse symptoms. If you take glibenclamide in large quantities for a long time, it will eventually lead to hypoglycemia, nephropathy and even death.

　　Which drugs illegally add glibenclamide?

　　According to experts, in the drug treatment of diabetes, except insulin, most of them are oral drugs. Oral hypoglycemic drugs are usually divided into three categories: western medicine hypoglycemic drugs, pure Chinese medicine hypoglycemic drugs and Chinese and Western medicine hypoglycemic drugs. Generally, pure Chinese medicine has weak hypoglycemic effect, slow onset and high safety. Western medicine hypoglycemic agents take effect quickly and have great toxic and side effects. The combination of Chinese and western hypoglycemic agents is based on the pure traditional Chinese medicine hypoglycemic agents, and incorporates the ingredients of western medicine hypoglycemic agents, which not only has the advantages of rapid hypoglycemic effect of western medicine, but also has the advantages of high safety of traditional Chinese medicine. According to the person in charge of the provincial drug evaluation center, at present, only three kinds of oral hypoglycemic drugs, such as Yikai Xiaoke Pill, are officially registered in China. It is not the first time to illegally add glibenclamide. In 2005, the Ministry of Health investigated and dealt with two cases-

　　○ On June 15th, 2005, the Ministry of Health issued a notice, requiring all localities to investigate and deal with some batch numbers of "Ku Le Kang Capsule" produced by Liaoning Healthy Weiye Biotechnology Co., Ltd.. The Ministry of Health pointed out that when the relevant departments of Jilin Province supervised and inspected the health food "Ku Le Kang" capsules (approval number: Wei Shi Jian Zi [2002] No.0588) produced by Liaoning Health Weiye Biotechnology Co., Ltd., they found that the products marked with certain batch numbers contained chemical drugs. The capsule shells of samples with batch numbers of 20041201 (not for sale), 20040902 and 20041201 contain the chemical drug glibenclamide, and the capsule contents with batch number of 20050401 contain the chemical drug gliclazide.

　　○ On October 9, 2005, Jiangxi Food and Drug Administration announced that the law enforcement officers of Nanchang Food and Drug Administration had tested the drug "Tangbikang Jiangtangning Capsule" labeled as batch number 20050403082 produced by Jilin Shenhui Pharmaceutical Co., Ltd.: glibenclamide was illegally added to this Chinese patent medicine.

Recently, the China Breast Cancer Screening Standard (T/CPMA 014-2020) proposed by China National Cancer Center was published online in chinese journal of cancer prevention and treatment. The correspondent is Professor He Jie, director of National Cancer Center and academician of China Academy of Sciences.

As a common cancer, according to the latest global cancer burden data released by the International Agency for Research on Cancer (IARC) of the World Health Organization in 2020, there were 2.26 million new breast cancer cases in the world in 2020, surpassing lung cancer (2.21 million cases) for the first time, becoming the largest cancer in the world, accounting for 11.7% of new cancer cases. Among the newly diagnosed cancer patients, one in every eight is a breast cancer patient. China is a big country with breast cancer. In 2020, there will be about 420,000 new cases of breast cancer and nearly 120,000 deaths.

Screening, improving the detection rate of early breast cancer and precancerous lesions, and timely and effective treatment are important measures to improve the prognosis of breast cancer and reduce the risk of death. The standards put forward suggestions on the population, measures, results and management of breast cancer screening in China. We have sorted out the relevant contents, hoping to help you better understand the knowledge of breast cancer screening.

Who should have breast cancer screening?

The standard suggests that people at high risk of breast cancer should be screened from the age of 40; The general risk population (all school-age women except the high-risk population) should be screened for breast cancer between 45 and 70 years old.

High-risk population

Women who meet any of the following conditions 1, 2 and 3 are at high risk of breast cancer.

1. Women with genetic family history, that is, women with any of the following: 1) First-degree relatives (mothers, daughters and sisters) have a history of breast cancer or ovarian cancer; 2) Among the second-degree relatives (aunts, grandmothers and grandmothers), two or more people suffered from breast cancer before the age of 50; 3) Among the second-degree relatives, 2 or more have ovarian cancer before the age of 50; 4) At least one first-degree relative carries a known pathogenic genetic mutation of BRCA1/2 gene, or carries a pathogenic genetic mutation of BRCA1/2 gene himself.

2. Have any of the following: 1) Age of menarche ≤12 years old; 2) menopausal age ≥55 years old; 3) Have a history of breast biopsy or surgery for benign breast diseases, or a history of atypical hyperplasia of breast (lobules or ducts) confirmed by pathology; 4) Use hormone replacement therapy of "estrogen and progesterone combination" for not less than half a year; 5) X-ray examination of breast after 45 years old suggests that the type of breast parenchyma (or breast density) is uneven compactness or compactness.

Note: Breast parenchyma types can be divided into fat type, scattered fibrous gland type, heterogeneous dense type (which may cover small masses) and dense type (which reduces the sensitivity of breast cancer detection).

3. Those who have any of the following two items: 1) No breast-feeding history or breast-feeding time less than 4 months; 2) No history of live birth (including never giving birth, abortion or stillbirth) or the age of first live birth ≥30 years old; 3) hormone replacement therapy using only "estrogen" for not less than half a year; 4) Abortion (including natural abortion and induced abortion) shall not be less than 2 times.

How to screen?

General risk population: breast ultrasound examination should be performed every 1-2 years; If you do not have the conditions for breast ultrasound examination, you should use mammography.

High-risk population: breast ultrasound combined with mammography is performed once a year.

How to understand the screening results?

Classification of diagnostic results of mammography

The diagnostic results of mammography are usually classified by the Breast Imaging Reporting and Data System (BI-RADS), which is formulated by American Radiological Society (ACR) and widely used internationally.

1. BI-RADS 0: The existing image failed to complete the evaluation, and other image examinations need to be added.

2. BI-RADS 1: normal, no abnormality was found in mammography. The possibility of malignancy is 0%.

3. BI-RADS 2: Benign findings, with definite benign changes and no malignant signs. The possibility of malignancy is 0%.

4. BI-RADS 3: Benign lesions that may be large. 0% < malignant possibility ≤2%.

5. BI-RADS 4: Suspected malignant lesions, but without typical malignant signs. 2% < malignant possibility < 95%.

6. BI-RADS 4A: low-grade suspected malignancy. 2% < malignant possibility ≤10%.

7. BI-RADS 4B: moderately suspected malignant. 10% < malignant possibility ≤50%.

8. BI-RADS 4C: highly suspected malignant. 50% < malignant possibility < 95%.

9. BI-RADS 5: Highly suggestive of malignant lesions with typical imaging features of breast cancer. Malignant possibility ≥95%.

Classification of ultrasonic diagnosis results of breast

The classification of ultrasound evaluation refers to the screening of National Comprehensive Cancer Network (NCCN) and the BI-RADS classification standard proposed by American Radiological Society.

1. BI-RADS 0: The diagnostic information obtained by ultrasound is incomplete and cannot be evaluated, and it needs to be evaluated after other imaging examinations.

2. BI-RADS 1: negative, no abnormality was found by ultrasound. The possibility of malignancy is 0%.

3. BI-RADS 2: Benign lesions, with definite benign changes and no malignant signs. The possibility of malignancy is 0%.

4. BI-RADS 3: Benign lesions that may be large. 0% < malignant possibility ≤2%.

5. BI-RADS 4: Suspected malignant lesions, but without typical malignant signs. 2% < malignant possibility < 95%.

6. BI-RADS 4A: low-grade suspected malignancy. 2% < malignant possibility ≤10%.

7. BI-RADS 4B: moderately suspected malignant. 10% < malignant possibility ≤50%.

8. BI-RADS 4C: highly suspected malignant. 50% < malignant possibility < 95%.

9. BI-RADS 5: Highly suggestive of malignant lesions with typical imaging features of breast cancer. Malignant possibility ≥95%.

Screening result management

1. BI-RADS 1 and BI-RADS 2 need no special treatment.

2.　BI-RADS 3：

The evaluation of mammography is BI-RADS 3, so it is advisable to reexamine the breast on the lesion side at the next 6 months, and reexamine the breast on both sides at the 12th and 24th months.

If the lesion remains stable, it can continue to be reexamined, and if it has not changed for 2-3 years, it can be reduced to BI-RADS 2. If the lesion disappears or shrinks during the reexamination, it can be directly evaluated as BI-RADS 2 or BI-RADS 1. Biopsy should be considered if suspicious findings are found in the lesions during the reexamination.

The breast ultrasound evaluation is BI-RADS 3, so it is advisable to have breast ultrasound reexamination in 3-6 months, and it can be reduced to BI-RADS 2 if there is no change after 2 years of follow-up.

3. BI-RADS 4A: Further imaging examination and biopsy are needed.

4. BI-RADS 4B: Further imaging examination is needed, and biopsy is appropriate.

5. BI-RADS 4C and BI-RADS 5: Biopsy should be performed.

According to the standard, the breast physiological characteristics and breast cancer epidemic characteristics of women in China are quite different from those in western countries, so we can’t copy foreign experience. Establishing breast cancer screening standards suitable for women in China will play an important role in improving the scientificity, feasibility and practicability of breast cancer screening and reducing the incidence and mortality of breast cancer.
