　　editorial comment/note

　　The ninth day of the ninth lunar month is the traditional Chinese festival "Double Ninth Festival", and it is also the "China Elderly Festival". In recent years, China’s population aging presents the situation and characteristics of large quantity, fast speed, great difference and heavy task. The state has issued a series of development plans, and defined the strategic objectives and implementation steps of active aging. The language life of the elderly is related to their quality of life and physical and mental health. It is the basic condition for the elderly to enjoy a happy old age and needs more social attention.

　　Li Na/painting

　　Aging has a global trend in contemporary times; Caring for the life of the elderly is a topic of universal significance. China is a country with a large population of elderly people, with the population over 60 years old reaching 260 million. The fourth sampling survey on the living conditions of the elderly in urban and rural areas of China shows that the living conditions of the elderly in China are generally good. The family status of the elderly is relatively stable, and their independence and discourse power are high; Living conditions are good, most of them have independent rooms, and the electrical equipment in the rooms is relatively modern; There are various leisure ways, including traveling, chess and cards, reading books and newspapers, walking and chatting, planting flowers and keeping pets, etc. Neighborhood relations are harmonious, and they often walk around and help each other.

　　The above survey reflects the overall living conditions of the elderly, but it still lacks the necessary attention to the language life, the core content of the elderly life. Language life, in short, is all kinds of social activities and personal activities carried out by using language as a bridge. The quality of language life has an important influence on the living conditions, quality of life, mental state, mental health and physical and mental pleasure of the elderly.

　　　Language living conditions of the elderly

　　In order to understand the real language life of the elderly, the author’s research group conducted a survey in more than 30 cities and rural areas in Jiangxi, Guangdong, Jiangsu, Chongqing and other provinces and cities in August 2022, and received 455 valid questionnaires. Among the questionnaire samples, 48% were male and 52% were female. Rural areas account for 46%, and urban areas account for 54%. Among them, 31% of urban elderly people come from rural areas to cities to help their children look after their children and do housework. 30% are 60 ~ 65 years old, 25% are 66 ~ 70 years old, 18% are 70 ~ 75 years old, 11% are 76 ~ 80 years old, 11% are 81 ~ 85 years old, and 5% are over 86 years old. Primary school education or below accounts for 60%, secondary school education (technical secondary school) education accounts for 31%, and university education or above accounts for 9%. On the whole, the respondents are low-educated and most of them are under 80 years old.

　　The survey found that there are some obvious deficiencies in the language life of some elderly people. In terms of language ability, most elderly people do not have language barriers in social interaction, but there are still 37% elderly people who often have language barriers caused by dialect differences in interpersonal communication outside their families. In terms of communication objects, the communication objects of the elderly in their daily lives are mainly middle-aged and elderly people, and the communication with young people, especially teenagers, is obviously insufficient. 83% of the elderly rarely communicate with teenagers, and 60% of the elderly even communicate with their children and grandchildren. 70% of the elderly said there was a generation gap in communication with middle-aged people, and 88% said there was a generation gap in communication with teenagers. In terms of speaking time and willingness to communicate, 46% of the elderly said that the daily speaking time was less than before, and 43% of the elderly said that their willingness to actively communicate was lower than before. In terms of network communication, many elderly people will use their mobile phones for shopping, information inquiry, social chat, entertainment, etc., and 41% of the elderly people interviewed said that they only use their mobile phones to make phone calls and can hardly do anything else; The elderly who can use WeChat account for 47%, but only 5% can use Weibo, email and other network applications. The vast majority of the elderly (88%) are still used to using the telephone to communicate. In terms of understanding buzzwords and new words, only 1% of the respondents said they were familiar with them, and 84% said they basically didn’t know them.

　　The survey results show that the limitations of the language life of contemporary elderly people are mainly as follows: cross-dialect communication is difficult, communication with younger generations is less, there is a generation gap with young people, the speaking time is reduced, the willingness to speak is reduced, digital products and new media are not familiar enough, and there is a distance between them and popular language and culture.

　　Physical and mental changes are important constraints.

　　Most elderly people are eager to keep up with the pace of language life, but some elderly people are unwilling to actively participate in social language life because of various objective conditions and subjective reasons.

　　Physical aging leads to the decline of cognitive ability and language ability, such as listening, vision, memory, pronunciation ability, vocabulary retrieval ability, topic control ability, fluency of language output, complexity of syntactic use, accuracy of language understanding, etc., which all decline with age, which makes the elderly (especially the very old) have practical difficulties in language use in social communication.

　　The change of social role has influenced the language living environment and wishes of the elderly. Everyone has to play many social roles in his life. These roles are usually arranged continuously, and each role is associated with a certain age or life stage. Aging will lead to the loss or interruption of some roles. For example, the elderly will change from the leading role of family, unit and society to a supporting role or even "no corner", which often becomes an important reason why some elderly people are unhappy or even self-enclosed. The elderly constitute a sub-cultural group. Members in the group can find a common language, and it is easier to know and realize themselves. However, there is a clear psychological distance from people outside the group, so the elderly often lack the subjective motivation to communicate with young people, and sometimes even deliberately avoid communicating with young people.

　　In addition, many elderly people who go to the city with their children have problems such as unfamiliar environment, few social opportunities caused by dialect barriers, single conversation object and narrow conversation topics, which may lead to intangible isolation and inner loneliness of the elderly, thus making them lack of healthy and colorful language life.

　　Work together to optimize the language life of the elderly

　　Physical aging is a natural law, but the psychological state can be adjusted. Only by overcoming the obstacles of subjective psychology can the elderly live a good language life, and families and society need to create convenient conditions for the elderly to live a good language life.

　　First, get rid of self-enclosed psychology and take the initiative to participate in communication.Old age is the most mature stage in life, with rich life experience and social experience, and accumulated a lot of tangible and intangible knowledge wealth. Schopenhauer, a philosopher, believes that the experience of the elderly gives them a holistic perspective to control the overall situation. Old people think comprehensively and deal with problems carefully, and can truly be far-sighted and far-sighted; The elderly are highly respected, deeply emotional and willing to contribute, and often become the core and pillar of units, collectives and families. The transformation of social roles has its objective inevitability. The elderly can actively participate in other forms of social interaction and reconstruct the new roles that are most suitable for them. This is the only magic weapon for the elderly to re-recognize themselves, maintain their vitality and improve their happiness index.

　　Second, actively carry out study and training to improve language ability.The elderly can choose appropriate language learning and training contents and methods according to their own basic conditions and hobbies. The common ones are: (1) Reading poems and prose aloud, which will not only help to exercise the function of pronunciation system, but also cultivate the body and mind. (2) Persist in reading and analyze some long and difficult sentences properly, so as to enhance the language processing ability. (3) Insist on telling stories, exercise memory ability and improve narrative ability. (4) Learning a second language can delay the decline of cognitive ability and language ability of the elderly. Many surveys show that, as one of several non-pharmacological strategies to improve the aging process and reduce aging defects, language learning training is not only helpful to improve the cognitive function and self-esteem of the elderly, increase social opportunities, but also significantly improve the sense of accomplishment and happiness of the elderly. It is a very important psychological treatment and rehabilitation tool.

　　Third, cross the digital divide and promote communication.Facing the dazzling application of mobile phones in the digital age, many elderly people fall into a deep digital divide, and travel, shopping, medical treatment, communication and access to information are greatly restricted. In fact, digital products also have their humanized side, and many mobile phone applications have launched old-age versions and large-character versions. Active use of digital products is of great help to the daily communication and language learning of the elderly, and can even become a "treasure chest" to delay aging. The elderly who have eliminated the digital barrier not only have a more convenient life, but also greatly enhance their self-confidence, and have a closer psychological distance with young people. For example, the elderly who often use friends circle and video chat have a fuller life, are more familiar with the joys and sorrows of young people, and also let young people know more about their hobbies, which invisibly enhances the feelings between generations.

　　Fourth, multi-parties care together to optimize the language life of the elderly.Respecting and loving the elderly is a fine tradition of the Chinese nation. An important way to practice the tradition is to help the elderly live a good daily life, including language life. In the family, young people should pay more attention to the psychological needs of their elders, introduce more anecdotes in life, and encourage the elderly to talk more and communicate more. If possible, they can also write memoirs, and don’t show boredom with the "nagging and nagging" of the elderly; Children and grandchildren who have lived in other places for many years can actively contact the elderly with the help of convenient modern communication means, which not only urges the elderly to talk more, but also makes the life of the elderly, especially the elderly living alone, less monotonous, and promotes the elderly to skillfully use digital products and promote the high-quality development of their language life. All enterprises, institutions and grass-roots communities should implement the national policy for the development of the cause of the elderly, provide convenient and suitable venues for the elderly, actively organize various cultural and sports activities for the elderly, and guide the elderly to go out often, make friends and chat more, so as to keep their body and mind happy. Academic circles should strengthen the research on the language of the elderly, explore the language characteristics of all kinds of elderly people and the language skills of communicating with them. In a word, the common care of the elderly by families, social organizations and academic circles is an indispensable external condition to ensure the elderly to live a good language life.

　　The living conditions of the elderly are an important indicator to measure social governance and social civilization. Living a good language life for the elderly is the basic condition for the elderly to enjoy a happy old age, which not only requires the elderly to participate in social activities with a positive attitude and actively integrate into the ever-changing times, but also requires all sectors of society to pay attention to caring for the elderly and create a warm family and social atmosphere for the elderly. "Mo Dao Sang Yu is late, and the twilight is still full of sky." Old age is a long life course, and no one can bypass this journey. May all old friends enjoy this wonderful sunset happily.

The Ministry of Industry and Information Technology officially announced the Outline of National Integrated Circuit Industry Development Promotion.

Many countries encounter heat waves, high temperature breaks through historical extremes, and climate warming intensifies the frequency of extreme weather.

A rare heat wave is raging in the northern hemisphere. At 6 o’clock on August 22, the Central Meteorological Observatory issued the highest level warning of high temperature in China-high temperature red warning for the 11th consecutive day. Not only in China, but also in Spain, Portugal, France, Britain and other places, heat waves with high temperature exceeding 40℃ have broken through historical extremes in many places, threatening human health, power supply, agricultural production and water resources.

Why is the heat wave coming? Will extreme weather become the norm in the future? According to the meteorologists interviewed, it is very rare to see the intensity and frequency of extreme weather this year. In addition to short-term direct meteorological factors, there has been a lot of evidence that this is closely related to long-term climate change. Climate change has once again sounded the alarm for the whole world.

High temperature and heat waves generally hit the northern hemisphere, and temperatures in many countries broke historical records.

The whole world is as cool and hot as this-at this moment, people in the whole northern hemisphere feel it particularly vividly.

"China has experienced the strongest high temperature process since there was a complete meteorological observation record in 1961. This process has the characteristics of long duration, wide range, high intensity and strong extremes." According to Zhou Bing, chief expert of climate service of the National Climate Center, as of August 21st, the duration of high-temperature events in China this summer (70 days), the coverage of high-temperature areas above 40℃ (1.5 million square kilometers), the maximum temperature intensity of a single station (45℃) and the number of stations with historical extremes broken or flat by the National Meteorological Station (330 stations) all set new records.

Looking around the world, the crimson and orange on the temperature map symbolize the high temperature weather above 35℃, which are widely distributed in Europe, North Africa, North America, East Asia and other places. In just one month, Europe experienced two rounds of heat waves. According to the World Meteorological Organization, the current heat wave sweeping Europe will continue, and the negative effects of climate change such as high temperature will last at least until the 1960s.

The decrease of river water level, the increase of forest and grassland fire risk, the drought of crops, the shortage of power and water resources … The heat wave brings not only somatosensory heat, but also a series of secondary disasters.

The unusually high temperature and rainfall are significantly less than in previous years, and the drought in many places in Europe is serious. "From the dry and cracked reservoirs in Spain to the drop in water levels of major rivers such as Danube, Rhine and Po, an unprecedented drought is sweeping across nearly half of Europe." The Associated Press reported that there was no obvious precipitation in most parts of continental Europe in the past two months, and some experts called it "the worst drought in 500 years".

The high temperature and drought caused the river water level to drop seriously, and the riverbed was exposed, making it difficult for ships to sail. The Rhine River is an important inland waterway in Europe, which flows through Germany, France, the Netherlands, Switzerland and other countries and is known as the "golden waterway". German federal and local waterway and shipping management agencies have warned many times recently that the waterway water level near many cities along the lower reaches of the Rhine River has set a new record, which has led to a sharp decrease in shipping volume and the actual load of ships is less than half of the normal situation.

Long-term high temperature combined with protracted drought has sharply increased the threat of forest fires. According to the data of the European Forest Fire Information System, more than 50,000 hectares of forests in France have been burned by fires this year, which is more than three times the average level in the past decade. Large-scale forest fires have also occurred in California, USA.

In the Po River region of Italy, severe drought caused rice fields to dry up and lack water. Local farmers estimate that this year’s rice harvest may be "halved". The German Farmers’ Association recently warned that in the case of continuous drought, we should be alert to crop failures and price increases. If it doesn’t keep raining as soon as possible, the harvest may be reduced by 30% or 40%.

Extreme high temperature also poses a threat to human health. "Heat will cause disease, and heat stress and high concentration of ground ozone will have a serious impact on health." Klaus reinhart, president of the German Medical Association, said about the impact of this wave of heat waves in Europe. The French health department warned that during the heat wave, the number of people seeking medical treatment increased significantly due to overheating and dehydration.

　Climate warming intensifies the instability of the climate system and is more likely to lead to extreme weather and climate events.

Why is the high temperature event "long standby"? Meteorological observations can provide direct and short-term explanations. High temperatures are often caused by specific weather systems, the most common of which is subtropical high. The area under its control is prevalent in downward flow. On the one hand, air subsidence will compress and warm up; on the other hand, the upward movement is weak, and there is little rain in partly cloudy.

"The extreme high temperature in the northern hemisphere is caused by multiple factors, and the continuous abnormal atmospheric circulation is a direct cause." Zhou Bing told reporters that the western Pacific subtropical high belt, the Atlantic high belt and the Iranian high pressure have all been strengthened in stages, thus forming a large-scale warm and high pressure belt around the northern hemisphere, which makes the hot air stay near the ground and cannot be dispersed, and then there is a high-temperature heat wave event.

La Nina climate events have contributed to the atmospheric circulation anomalies. La Nina refers to the phenomenon that the seawater in the equatorial, Middle East and Pacific Ocean is unusually cold, which can cause changes in atmospheric circulation and then affect the climate. "Since this spring, the La Nina event in the equatorial eastern Pacific has intensified, and the SST anomaly in the Indian Ocean has pushed the subtropical high to continue to increase." Zhou Bing said.

Considering from a longer climate scale, global warming is the background of high temperature heat wave in the northern hemisphere. The long-term climate change caused by human activities is the deep-seated reason for the increase in the frequency and intensity of extreme weather.

"Climate warming will change the global ocean and atmospheric circulation situation, and further affect the local climate through the interaction between ocean and atmosphere, land and atmosphere. Climate warming intensifies the instability of the climate system and is more likely to lead to extreme weather and climate events. " Chao Qingchen, director and researcher of the National Climate Center, told the reporter that the overall feature of climate change is to aggravate the instability of the global climate, and the impact and risks on natural ecosystems and economic and social systems are becoming increasingly serious.

According to the sixth assessment report of the United Nations Intergovernmental Panel on Climate Change (IPCC), global warming is occurring at an unprecedented rate since 2000 in the last 50 years. The report released by the World Meteorological Organization shows that in the past 50 years, due to the impact of climate change, the number of disasters has increased fivefold and the disaster losses have increased more than sevenfold.

"Climate change has led to a trend of frequent, extensive, strong and concurrent extreme weather and climate events." Zhou Bing mentioned that the compound disasters caused by extreme weather are increasing. High temperature, heat wave and drought may occur more frequently, accompanied by the risk of wildfire; In some places, the possibility of compound flood has increased, and this possibility will continue to increase due to rising sea level and increasing precipitation intensity.

According to Zhou Bing’s observation, compared with several high-temperature events since the beginning of this century, this year’s heat wave has an obvious trend of advancing and strengthening in both the starting time and the extreme degree.

In the future, will the "hottest" become the norm?

According to the World Meteorological Organization, due to the influence of climate change, it is expected that extreme high temperatures will appear more frequently and more strongly in the future. Nalis, a spokesman for the organization, said that if greenhouse gas emissions continue to rise, global warming will be even greater, and what we are experiencing now is only a "harbinger of the future".

"Due to the intensification of global warming, the frequency of events such as extreme high temperature and extreme heavy precipitation has accelerated and the cycle has been shortened. The original once in 50 years has become once in 20 years or even 10 years. Every 1℃ increase in global temperature leads to an increase of 7% in extreme precipitation intensity. Every 0.5 C warming in the future will significantly change the frequency of extreme temperature events. " Zhou Bing said that the extreme high temperature staged in the world may herald the coming of the "40 C era in the northern hemisphere", but this needs further observation and scientific confirmation.

　Rare extreme weather has sounded the alarm for the whole world, and it is urgent to deal with climate change.

The heat wave even rushed to the polar regions. "The temperature in Greenland is close to 60 degrees Fahrenheit (about 15.5 degrees Celsius), and warm weather like today is enough to wear short sleeves." On July 19th, in Greenland, an extremely cold place, a reporter appeared in the news screen wearing a thin T-shirt.

Greenland is the largest island in the world, most of which is located in the Arctic Circle, and about 80% of the island’s land is covered by ice sheets. This summer, the temperature in the Arctic Circle soared to 32.5℃, and the ice sheet in Greenland is melting at an alarming rate. According to data from the National Snow Data Research Center, from July 15th to 17th, the Greenland ice sheet lost about 6 billion tons of ice every day, enough to fill 7.2 million Olympic swimming pools. If the negative effects of climate change such as high temperature continue, the Greenland ice sheet will melt completely and the global sea level will rise by 7.5 meters.

In mid-March this year, the temperature in some parts of the Arctic was about 30℃ higher than the average level in the same period of last year. Many research stations in Antarctica have measured record high temperatures. The temperature at Concordia Antarctic research station is about 40℃ higher than the average level in the same period of last year, and the temperature at Kunlun Station in Antarctica in China has increased by 38.1℃ within 4 days. "The seasons in the north and south poles are opposite, but it is rare to see extreme hot weather at the same time. This is absolutely unusual." Zhou Bing said.

All kinds of unusual things have sounded the alarm for the whole world.

The research of Nobel Prize winners in physics, Shuro Kuniko and Klaus Hasselman, intuitively pointed out the relationship between greenhouse gas emissions and global warming: if the atmospheric carbon dioxide concentration doubles, the global average temperature will rise by more than 2℃. Accordingly, the Paris Agreement puts forward the goal of "keeping the global average temperature rise within 2℃ relative to the pre-industrial level by the end of this century and making efforts to control the global average temperature rise within 1.5℃".

Significantly reducing greenhouse gas emissions is related to the future and destiny of mankind. In 2021, the global average temperature was 1.11℃ higher than the pre-industrial level. In April this year, the IPCC said through the report of Working Group III in the Sixth Assessment Report that the world is at a crossroads where it is now or never. "If you want to control global warming within 1.5℃, you should either act now or never (fail to meet the standards), so all departments need to carry out deep emission reduction." Jim Ski, co-chairman of Working Group III, said.

"China has actively participated in global climate governance, implemented a national strategy to deal with climate change, promoted industrial restructuring and energy structure optimization, and accelerated the construction of a’ double carbon’ policy system, and achieved remarkable results in carbon emission reduction." According to Zhou Bing, in the past decade, China’s energy consumption intensity has been reduced by 26.2%, which is equivalent to using about 1.4 billion tons of standard coal less and emitting about 2.94 billion tons of carbon dioxide less. In 2020, China’s carbon emission intensity will decrease by 18.8% compared with 2015 and 48.4% compared with 2005, exceeding the target of 40%-45% promised to the international community.

The unbearable heat has also made people have a more real experience of global warming. "In terms of emission reduction, we often say that there are five levels: international social experience and mutual cooperation, national or regional independent contributions and policy-level attention, industry and enterprise carbon emission constraints and efforts, active participation of communities and the public, and scientific dissemination of green and low-carbon concepts of associations." Zhou Bing said that the public is not detached from the issue of climate change, and energy conservation and emission reduction require the joint efforts of all walks of life in the whole society.

Pay equal attention to mitigation and adaptation, enhance climate resilience and build a climate-adaptive society.

Reducing emissions is not the only action to deal with climate change. Mitigation and adaptation are two major strategies to deal with climate change, which complement each other and are indispensable.

"Mitigation refers to reducing greenhouse gas emissions through long-term adjustment of economic systems and natural ecosystems such as energy and industry. Adaptation refers to the climate change that has occurred and is expected to occur, through the adjustment of natural systems and human systems, to reduce the adverse effects of climate change on social and economic development and ecosystems, and to make full use of favorable factors. " Nest clearing dust said.

Slow down is the fundamental solution, but adaptation is also essential to solve the immediate problems. In the view of Chao Qingchen, the necessity can be understood from two aspects: first, climate change has already occurred, and its negative impact cannot be minimized if it is not adjusted and changed through adaptive means. Secondly, it takes time for mitigation measures to have an effect. Greenhouse gases have a long "life span". Even if emissions are reduced, past and present emissions will continue to affect the climate system, and the consequences will be manifested for a long time, such as sea level rising in the next few hundred years. Therefore, for the risks that have occurred and are about to occur, we must rely on adaptive measures to reduce the adverse effects.

China has always been adhering to the concept of paying equal attention to mitigation and adaptation, and taking active adaptation to climate change as an important part of implementing the national strategy of actively responding to climate change. Not long ago, the National Climate Change Adaptation Strategy 2035 was released, and it was proposed that by 2035, "a climate-adapted society will be basically completed".

Huang Gang, a second-level researcher in lasg, said in an interview with this reporter that according to the Action Plan for Urban Adaptation to Climate Change, the goal of building a climate-adapted city is to "significantly enhance the city’s ability to cope with waterlogging, drought and water shortage, high-temperature heat waves, strong winds and freezing disasters, and comprehensively improve its ability to adapt to climate change". "Similarly, a climate-adaptive society is a society with strong adaptability under changing climate conditions."

Try your best to prevent, focus on reducing, enhance climate resilience, and improve disaster prevention and mitigation capabilities. "Strengthening the early warning of extreme weather and climate events is the first line of defense for disaster prevention and mitigation." Chao Qingchen said that in the future, it is necessary to strengthen the comprehensive on-the-spot monitoring of extreme weather and climate and the understanding of the fine characteristics of disastrous weather and climate. Zhou Bing believes that global warming has brought new challenges to meteorological disaster prevention and mitigation, and it is necessary to continuously strengthen the disaster risk management ability of the whole society and the public’s awareness of disaster prevention and mitigation to minimize the impact of disasters.

Many interviewed experts said that in the face of increasingly frequent and intense extreme weather, we should not only focus on the present and solve the immediate problems, but also focus on the long-term and make a comprehensive response. For example, extreme weather affects agricultural production and energy supply, so we should take precautions and prepare adequate countermeasures. For another example, urban planning should take extreme precipitation and extreme high temperature into consideration, build infrastructure such as flood control and drainage systems that can withstand extreme weather, provide more shade places, and use more environmentally friendly and heat-insulating building materials.

The heat wave will eventually ebb, but the climate problem will not disappear, and extreme weather will not disappear. The challenges brought by climate change to mankind are realistic, severe and long-term, and each of us has the responsibility to "cool down" the earth.

Four tests that must be done during physical examination can help to find out the hidden dangers of cancer. Don’t do it to save money.

Nowadays, people pay more and more attention to health. Even if there is no discomfort, many people insist on doing a general physical examination every year. This habit is very good.

As the saying goes, nip in the bud, many diseases are not without treatment opportunities, but because they are not taken seriously in the early stage, so the diseases cannot be treated in time. The purpose of physical examination is to check the possible safety hazards of the body in time, such as cancer.

However, for non-medical professionals, there are many physical examination items, and going to the physical examination center will also be confused. How should I choose so many medical examination packages?

In fact, no matter what kind of medical examination package you choose, you should remember that these four examination items are necessary, because they are closely related to health and can monitor whether your body is at risk of cancer in time.

1. Gastroscopy

The stomach is an important digestive organ of the human body, and it is also the organ that is most prone to problems at ordinary times. People may not pay much attention to the pain and soreness of the stomach, and think that taking some medicine for stomach diseases will disappear. However, there are many hidden diseases, which are not easy to be found by symptoms in the early stage. For example, the risk of malignant gastric mucosa must rely on gastroscopy to find out whether the stomach has lesions more intuitively.

More importantly, gastroscopy can also do gastric mucosa biopsy and gastric polyp removal, which is really useful for people who often have chronic gastritis to check the risk of gastric cancer.

Especially after the age of 40, the risk of gastric cancer will also increase. Although it is not easy to do gastroscopy, for the sake of health, we still have to choose to stick to it.

It is suggested that people over 40 years old, people with family history of stomach trouble or long-term stomach discomfort should have regular gastroscopy.

2. colonoscopy

Colorectal cancer is a malignant disease of digestive system, the incidence of which is increasing year by year, which is closely related to people’s daily diet structure and habits. For example, common rectal cancer and colon cancer, because they are not taken seriously in the early stage, usually choose to have an examination when there are obvious symptoms, which is probably too late.

In fact, colonoscopy is the most direct means of investigation. By looking directly at the colon and rectum, we can investigate tiny intestinal lesions. If we suspect that there is a tendency of malignant lesions, we can take a biopsy to take the lesion tissue for biopsy, and then decide the follow-up diagnosis and treatment plan.

Many people find it difficult to accept colonoscopy, because it is very painful. In fact, you can choose painless colonoscopy when doing physical examination, which will not bring you pain, but also check the intestinal health. Why not?

It is suggested that people over 50 years old should have colonoscopy every 5-10 years, and those with family history may need more frequent examination.

3. Liver B-ultrasound examination

The liver is an important organ of human body, which has many functions, such as metabolism, synthesis, digestion, etc. However, the liver is also the most prone to pathological changes among important organs of human body. In the early stage of liver disease, it usually doesn’t show obvious symptoms, but when people feel that they have liver discomfort, such as dull pain and abdominal distension, they may have missed the best treatment opportunity.

Therefore, it is necessary to observe the health dynamics of the liver in time. This observation is not with eyes, but with the help of imaging examination, and on this basis, the structure of the liver is scanned. Generally speaking, liver B-ultrasound is the most suitable for preliminary screening. In the early stage of liver disease, B-ultrasound can scan liver parenchyma and other parts to find suspicious pathological signals. If there is a risk of pathological changes, you can consider the next diagnosis and treatment, such as liver biopsy.

For the asymptomatic general population, low-dose CT screening can be considered to reduce radiation exposure.

In a word, B-ultrasound examination of liver is of great reference value for caring for liver health.

4. Pulmonary imaging examination

The incidence of lung cancer is still high, which is related to people’s living habits and living environment. Air pollution and smoking are all important factors that induce lung cancer. In the early stage of lung cancer, if we can take timely and effective measures to investigate, we can obviously improve the prognosis and prolong the life of patients.

Lung CT is an important means to examine the lungs. Many people think it is expensive, so they don’t do it when doing physical examination. In fact, this consideration is wrong.

Compared with delaying the treatment of lung cancer, the cost of lung CT is not very expensive at all, but it can help to find the risk of early lung malignant transformation. Therefore, it is recommended that you do a lung CT once a year when you have a physical examination, which is worthwhile for screening lung diseases.

The above four inspection items are relatively cost-effective, and can check the potential risk of body cancer. Finally, I would like to remind you that this article is for reference only and cannot replace professional medical advice.

Optimization of cost performance-Changan Auchan X5 riders： listing will be a fire.

First of all, the appearance of this car adopts a unique design language. In terms of muscle sense, the overall design of Changan Auchan X5 is individual, and the front face of the whole vehicle looks full, with sharp headlights on both sides, and the internal light groups are patchy and bright when lit. The rising side of the double waistline design creates a sense of readiness and looks active. The front end adopts 17-diameter wheels, which helps to highlight the shape of Changan Auchan X5. In the design of the rear of the car, this model has created a sporty posture. The taillight design of the new car is even more eye-catching, and the rear exhaust port is a double exhaust layout.

Coming to the red decoration of Zhongkong, the interior style of Changan Auchan X5 gives people the feeling of elegance. The steering wheel made of genuine leather is made of plastic and feels good. The whole center console looks full of texture under the blessing of a large area of plastic-lined materials, and the front row is also equipped with a manual air conditioning control system to freely debug the most comfortable space atmosphere. And there are ergonomic seats in the car with a sense of movement.

The length, width and height are 4490×1860×1580mm respectively, and the wheelbase has reached 2710mm. In the same class, the wheelbase of Changan Auchan X5 ranks 51st. The design of skylight also increases the subjective space feeling of front and rear passengers. Among the models of the same price and class, the trunk volume of Changan Auchan X5 ranks 56th. It can basically meet the luggage space for family travel. But there is no extra hidden storage space.

Changan Auchan X5 is equipped with a combination of 1.5 turbocharged engine (direct injection) and wet dual clutch (DCT). It will definitely bring unforgettable control charm. Ranked 31 ST among 80,000-120,000 SUV models.

Changan Auchan X5′ s active/passive safety configuration is complete, includingAutomatic parking、Zero tire pressure endurance tire、Automatic parking、Steep slope descent、hill start assist control、knee airbag、HUD head-up display、Anti-lock braking (ABS)、Braking force distribution (EBD/CBC, etc.)、Brake assist (EBA/BAS, etc.)、Traction control (ASR/TCS, etc.)、Active noise reduction、Engine start and stop、Side safety air curtain、Wireless charging of mobile phone、night vision system、LED daytime running lights、Forward reversing radar、Tire pressure monitoring、Steering wheel heating、Body stability control (ESP/DSC, etc.)、Rear reversing radar、Fatigue reminder、Remote parking、Child seat interface、Lane keeping (LKAS)Equal configuration.

Covering Xuanyi Classic／Hacker Classic, Dongfeng Nissan launched a limited-time discount.

A few days ago, we learned from Dongfeng Nissan’s official channels that its Classic and Classic launched a limited-time discount. Among them, Xuanyi Classic reduced the price by 38,800 yuan in a limited time, starting from 69,800 yuan after the discount; Hacker Classic will reduce the price by 27,100 yuan in a limited time, starting from 98,800 yuan after the discount, and the activity time will be from April 20, 2024 to May 6, 2024.

Xuanyi classic

Specifically, the official guide price of Sylphy Classic is 108,600-122,600 yuan, and there are three models: comfort version, luxury version and exclusive version. If you want to buy it, I suggest choosing the entry-level comfort version. Take the price of 69,800 yuan after the discount as an example, and the landing price is about 80,000 yuan.

Although the configuration is not rich, there is not even a central control panel, but these are not big problems, which can be solved by later installation. And the landing price of about 80 thousand yuan can buy such a well-known joint venture car, and it is still automatic. For many consumers with limited budget and pragmatism, the cost performance is still very good.

As a family car, it can be without rich configuration, but it must be economical and worry-free. Sylphy Classic is equipped with a 1.6L naturally aspirated engine and matched with CVT gearbox. This power combination undoubtedly meets household needs well. According to a fuel consumption App query, it can be known that the fuel consumption of Xuanyi Classic Comfort Edition comprehensive road conditions is 6.92L/100km, and the minimum fuel consumption is 5.98L/100km, which is relatively fuel-efficient.

In addition, this 1.6L+CVT power combination has been tested by the market for a long time. You can dislike its power meat, but you can’t pick out much trouble in terms of stability. In addition, thanks to the large amount of possession, it is also very cheap to maintain at ordinary times. Just find an auto repair shop on the roadside and you can get it for two or three hundred yuan.

Xiaoke classic

The official guide price of hacker classic is 125,900-145,900 yuan, and there are three models: comfortable version, leading version and intelligent version. Hacker Classic is actually the previous generation of hackers. After the third generation of hackers went public in August last year, Dongfeng Nissan learned the experience, and did not rashly stop production of the previous generation models. Instead, like Sylphy Classic, it was named Hacker Classic and sold together with the third generation models.

Judging from the market effect, this move is undoubtedly correct, because hackers and classics still occupy a large proportion among the models sold, because of the greater discount.

If you want to buy it, the author also recommends the entry-level comfort version, and directly pursues the ultimate cost performance. Based on the price of 98,800 yuan after the discount, it landed at around 110,000 yuan. Unlike Sylphy Classic Comfort Edition, Hacker Classic Comfort Edition is slightly richer in configuration, with 5-inch LCD instrument cluster, front keyless entry, one-button start, remote start, leather-like seat, 9-inch central control screen, Nissan Connect super-smart system, daytime running lights, electric adjustment of exterior rearview mirror, dual-zone automatic air conditioning, rear air outlet, PM2.5 filtering in the car and other configurations.

I feel that this configuration performance has been able to meet the daily needs, and the selling point of hacker classic is the 2.0L engine. Unlike first-and second-tier cities, most consumers in third-and fourth-tier cities and small counties in China may not be able to drive a few times all year round after buying a car, and only use it when visiting relatives and friends during the Chinese New Year, and the car is basically in a state of parking. Therefore, when they buy a car, they don’t have too high requirements on configuration, as long as they can walk instead of walking, and they should consider more about face and whether they can use it later.

And these two requirements, hacker classic just have. On the face, Nissan’s brand influence is not as good as before, but at least it is still a quasi-first-line joint venture brand at present; In terms of peace of mind, this 2.0L naturally aspirated engine code-named MR20 has been tested by the market for a long time. Although it is not technologically advanced, there is no need to worry about its stability.

However, it should be noted that the official added the word "Qi" after the preferential prices of the two models. I wonder if this implies that if you want to get the bare car prices of 69,800 yuan and 98,800 yuan, you need some additional conditions, such as buying a car by stages.

Let me ask you, how much is the minimum price of Xuanyi Classic and Hacker Classic in your place?

Attacked in Russia. Who did it？

　　A village in Belgorod was attacked.

　　Gladcov, governor of Belgorod, said on the 22nd that the Ukrainian reconnaissance and sabotage team sneaked into the state to launch an attack, resulting in eight people being injured, and the state entered a state of anti-terrorism action. On the same day, Uzbekistan denied that it was related to this matter, saying that the above actions were carried out by "anti-Russian armed forces."

　　Gladcov said: I am now in the Gryvolong District. The situation here is still very tense, and a (Ukrainian) sabotage reconnaissance team sneaked in here.

　　Comprehensive CCTV Chinese international and reference news

　　Governor of another state: drones attack local houses

　　Gladcov said that many buildings, including houses, were thrown explosive devices by drones. The Russian armed forces, the Border Guard, the National Guard and the Federal Security Service jointly took all necessary measures to eliminate Ukrainian saboteurs, and most residents in the Gryvolong district had been evacuated.

　　On May 23, local time, the governor of Belgorod, Russia, announced that the Russian air defense system shot down several drones in Belgorod, the capital of the state, and nearby areas. According to preliminary statistics, no casualties were caused, and the specific losses on the ground are being counted by local authorities.

　　Russian Presidential Press Secretary peskov said that relevant departments have reported this matter to Russian President Vladimir Putin. Peskov pointed out that Uzbekistan tried to use sabotage to divert people’s attention from the situation in Bakhmut.

　　Belgorod implements "anti-terrorism mechanism"

　　Subsequently, the Russian authorities implemented an "anti-terrorism mechanism" in the Belgorod region in the southwest of the country on the 22nd, and implemented a series of special measures and temporary restrictions, including checking personal identity documents and suspending the production and business activities of explosive and radioactive substances and chemical and biological products.

　　Gladcov said in a statement: "In order to ensure the safety of citizens in Belgorod, a legal mechanism against terrorism was introduced today."

　　The report pointed out that the mechanism gives special powers to the security department and requires the implementation of a series of restrictions and preventive measures, including strengthening security inspection, identity verification and communication monitoring. The Russian authorities can also transfer people living in the affected areas.

　　The Ukrainian side claimed that it was "anti-Russian armed forces"

　　Podolyak, adviser to the Office of the President of Ukraine, responded that Ukraine had nothing to do with this matter. The Ukrainian state news agency quoted Andrei Yusov, spokesman of the General Intelligence Department of the Ukrainian Ministry of National Defense, as saying that the above actions were carried out by "anti-Russian armed forces" and their military operations in Belgorod were aimed at establishing a "safe zone for protecting Ukrainian civilians". Yusov denied that the operation was related to Uzbekistan, saying that "only Russians participated in the operation that day".

　　Russian Defense Ministry announced:

　　Defeat Ukrainian armed groups

　　According to the Russian satellite news agency, the Russian Defense Ministry announced on the 23rd that the Russian army defeated the Ukrainian armed gang and destroyed more than 70 people.

　　The Russian Defense Ministry told reporters: "In the anti-terrorism operation, Ukrainian nationalists were surrounded and defeated under the active actions of air strikes, artillery fire and border guards in the western military region." The Russian Defense Ministry pointed out that the remnants of the nationalist gang returned to Uzbekistan, but the Russian army continued to crack down until it was completely eliminated.

　　The Russian Defense Ministry said: "In this process, more than 70 Ukrainian terrorists were destroyed, and 4 armored combat vehicles and 5 pickup trucks were destroyed." The Russian Defense Ministry also released a video, which it claimed showed the picture of the Ukrainian saboteur gang being destroyed.

After the first debate, Trump and Biden both said that they won the American netizens： Anyway, we lost.

　　Xinhua News Agency, Washington, September 30 th On the evening of September 29 th, US Eastern Time, US President Trump, who was seeking re-election, held the first TV debate with Democratic presidential candidate Biden, and had a fierce confrontation on the six major issues previously determined for one and a half hours.

　　Under the "eyes of the public", the two sides frequently rob words, label, personal attacks and other behaviors. American media and netizens thought that the scene was chaotic and the performance was disappointing. Others commented that no matter who won the first debate, the United States lost anyway.

　　On September 29, a video shot in Arlington, Virginia, USA showed that US President Trump (left) and US Democratic presidential candidate Biden participated in the first presidential debate in the 2020 US election. Xinhua News Agency reporter Liu Jie photo

　　"Everyone is talking and no one is listening."

　　The first debate was hosted by Chris Wallace, the host of Fox News. In about 90 minutes, Trump and Biden debated six topics, namely, the Federal Supreme Court, COVID-19 epidemic, economy, urban race and violence, their political records and election fairness.

　　According to the original rules, the host started each topic with a question, and Trump and Biden each took two minutes to answer, and then they debated each other. The moderator tried to lead a more in-depth discussion However, judging from the live broadcast, the two frequently interrupted each other, and there were many personal attacks. Wallace intervened many times to keep order.

　　Judging from the media comments and netizens’ comments, it is a common impression that the scene is chaotic and disappointing.

　　During the debate, both candidates kept interrupting each other and even attacked each other with insulting words. For example, Biden called Trump "not smart" and a "clown" who once shut Trump up. Trump called Biden "not smart" and even personally attacked Biden’s family. After the debate, some American media found that many of their statements were misleading, lacking evidence or even completely wrong after fact checking.

　　"This debate is like this country, where everyone is talking and no one is listening … … A mess. " Aksil Aosi, a news website, commented immediately after the debate.

　　Jack Tapper, the anchor of CNN, said that the debate was like a "car accident scene".

　　Some American netizens commented that this may be the first time that American TV viewers are looking forward to inserting advertisements in the program.

　　Ian Bremer, chairman of Eurasia Group, said that this was the "worst presidential debate" he had ever seen, and this debate was "a joke, a farce, an embarrassment and a shame".

　　Mark hertling, a retired US Lieutenant General, said that the outside world is watching the debate, but I’m afraid it’s as unbelievable as most American audiences.

　　"I win" and "America loses"

　　Judging from the past, the debate has limited influence on the election. Affected by the epidemic this year, the election campaign failed to be carried out in the traditional way, and the geometry of the impact of the debate on the election remains to be seen.

　　However, the two sides clearly understand the gameplay of the election campaign in the new media era, and the end of the live debate is not really the end. After the debate, the two campaign teams have their own strategies and manpower to continue to stir up hot topics, deliver golden sentences and create hot spots for supporters, media, internet and other different groups or platforms, in order to promote the development of public opinion in their own direction.

　　After the debate, both the Trump team and the Biden team claimed that they were the better performers in emails sent to their supporters.

　　The Trump team said in the email that this debate will "leave a name in the history of history", while the "fake news" media "will only lie".

　　The Biden team said in an email that voters, the media and even some Republicans thought Trump had lost the debate.

　　Although the debate scene is full of sparks, it is hard to say whether it can arouse the enthusiasm of voters.

　　Ford O’Connell, a Republican policy analyst, believes that both sides have tried to mobilize the enthusiasm of their respective ticket positions in the heated debate, but the effect is doubtful.

　　It’s hard to say who got the upper hand in the first debate, but many "see through" commentators think that the "loser" is obvious.

　　NBC White House reporter Peter Alexander tweeted: "America lost tonight."

　　Andrew Yang, a Democrat who participated in the presidential campaign before, said: "I think Biden has the upper hand, but I always feel that the United States has lost."

　　Some netizens lamented that this kind of debate only needs one time, and the remaining two rounds need not be done. (Reporter: Liu Yang, Deng Xianlai, Sun Ding, Xu Jianmei; Video: Tan Yixiao, Hu Yousong; Editor: Sun Hao, Wang Fengfeng; Edit: Wang Pei)
