Experts: Lou Futian wants to stop outdoor exercise Date: 2017-01-04 14:27
The days of haze in Hangzhou still last for several days. The same as smog irritates people's nerves, it is a sensational data on WeChat: Beijing’s lung cancer incidence rate has increased by 43% in the past decade. Some commentators believe that this has something to do with hazy weather in Beijing. Is smog really the culprit?
In some hospitals in Hangzhou, it is no longer a matter of two days that the patients in the respiratory department are exposed. Is it really caused by haze?
According to the Central Meteorological Observatory, Huanghuai in North China will wait until the arrival of the cold air on the 5th. In other words, the smog in Hangzhou will slowly dissipate at least five days later. What protective measures should we take in these three days and ten days?
Business Daily reporter answered for you one by one.
The incidence of lung cancer in Beijing has increased by 43% in the past ten years. Beijing expert Ruan Ye says that the actual growth rate is 1.2%.
In the past few days, with the onslaught of fog, a message in the WeChat circle of friends has also ignited: The incidence of lung cancer in Beijing has increased by 43% over the past decade. Some commentators believe that this has something to do with hazy weather in Beijing.
In April last year, the Hangzhou CDC released data on Hangzhou cancer profile in 2015. Among them, the top 5 cancers in Hangzhou in 2015 were lung cancer, thyroid cancer, stomach cancer, breast cancer, and liver cancer.
In connection with this news, and the frequent occurrence of hazy weather in Hangzhou recently, many people are worried that smog may have a positive correlation with lung cancer.
In fact, the figure of 43% incidence has been refuted as out of context.
Wang Ning, deputy director of the Beijing Cancer Prevention Office, wrote that the information came from the Beijing Municipal People's Government's 2013 Health and Human Health Report published on June 12, 2014. 1.2.1 Lung Cancer Chapters Incidence of Lung Cancer In 2003, 44.56/100,000 rose to 63.84/100,000 in 2012. On the surface, the growth rate is 43%, but the calculation growth rate is to be excluded from the aging of the social population. Therefore, the direct calculation of the annual crude morbidity rate cannot scientifically reflect the trend of lung cancer incidence, and it must be standardized before age comparison. Sex. The same-page report pointed out that the average annual growth rate of lung cancer among elderly people with lung cancer from 2003 to 2012 was 1.2%, which is a reference data.
Haze is a carcinogen
It is important that adults over the age of 40 are in a timely checkup
Although the data on the growth rate of cancer in Beijing has been rumored, it is undeniable that the haze's lethality is not small.
Wu Zhibing, director of the Tumor Hyperthermia Center at Hangzhou Cancer Hospital, said that haze must be a pathogen and a carcinogen, which is relevant to the increase in the risk of lung cancer.
From the essence, it is a particle with a diameter of less than 2.5 microns in the air. It can enter the body through the respiratory system such as the bronchus. The lung that is directly affected is the lung. Once in the lungs, it cannot be metabolized. If these particles carry germs and viruses, they will have a health impact on the respiratory tract and increase the probability of suffering from respiratory diseases.
A paper published in the July 2015 issue of the Journal of Thoracic Disease states that smog pollution is a potential cause of lung cancer. Japanese scholar Yorifuji finds that people are exposed to PM. It will significantly increase the risk of lung cancer. In particular, exposure to PM10 and PM2.5 increased the risk of lung cancer by 1.51 and 1.55, respectively. In 2002, Dr. Pope of the United States found that prolonged exposure to contaminated haze increased lung cancer mortality and heart disease mortality. Long-term follow-up data showed that for every 10 ug/m3 increase in PM2.5 concentration, lung cancer mortality will increase by nearly 8%. More animal experiments show that the haze is dissolved in the solvent and injected into the mouse's skin, causing tumor growth on the mouse's skin.
It should be noted that the increase in the risk of lung cancer due to haze is based on a long-term exposure. In fact, many cancers are induced. 90% of the causes are environmental factors, including the dietary environment and the respiratory environment. Most cancerous cells are caused by long-term stimulation based on chronic inflammation. Wu Zhibing said that at present, the average incidence of lung cancer in China is 50 per 100,000. The factors that have a close relationship with the incidence of lung cancer include smoking, kitchen fumes, indoor air pollution such as decoration of chemical materials, and long-term dust environment work.
However, Wu Zhibing also stated that because the current clinical studies, epidemiological studies, and animal studies on smog are all foreign data, they cannot be completely copied to our country. Specifically, we need an objective study by our country's disease control center or epidemiological research experts to prove whether smog is related to the occurrence and severity of lung cancer.
For cancer, early detection and early treatment are the best methods of prevention. Adults over the age of 40 are recommended to undergo at least one comprehensive cancer-related physical examination at least once a year, including low-dose spiral CT, tumor markers, B-ultrasonography, and other imaging studies. For the treatment of abnormal nodules, they should be examined under the guidance of a doctor. Or surgical treatment or regular review. Wu Zhibing suggested.
A three-day cough progressed to a pneumonia outpatient visit to the respiratory department last November.
In addition to the keyword carcinogen, smog and respiratory diseases are also closely related.
On these days, the respiratory medicine clinics in major hospitals in Hangzhou were full, and many experts said that the fullness of respiratory medicine clinics has a certain relationship with smog.
Yesterday, Dr. Wu Xiaohui, director of the Department of Respiratory Medicine of the Hangzhou Red Cross Hospital, said that the amount of outpatients in respiratory medicine was significantly higher than usual at the recent time. There was a coughing sound everywhere in the consulting room and outside corridors, and the volume of outpatient visits increased sharply. There is a certain relationship between haze.
Haze and haze in patients with respiratory disease is still very large, most patients are upper airway infections, cough is severe, and the disease progressed rapidly, early cough and less dry cough, often three or five days to develop a thick clam, fever situation . Wu Xiaohui said.
The 60-year-old Zhou Dabo coughed for five days and later went to see him and asked Wu Xiaohui nervously. I had a pneumothorax before and now I would cough if the cough is too severe. Under the request of the patient, Wu Xiaohui arranged for Zhou Dabo to have a lung. CT, confirmed bilateral pneumonia, another 50-year-old Wang Dabo coughing time is shorter, only 3 days, he told Wu Xiaohui, the beginning was just a dry cough but yesterday morning cough bleeding, and my heart was a little panic so to the doctor, lungs CT findings also show pneumonia. Under normal circumstances, the general respiratory infection should develop into pneumonia.
One day, Wu Xiaohui admitted 105 respiratory patients, including patients with various respiratory diseases such as sinusitis, asthma, emphysema, and old chronic bronchitis. The same out-of-hospital situation also occurred in other hospitals.
Jiang Jin, chief physician of the Department of Respiratory Medicine of Xinhua Hospital in Zhejiang Province, also said that the number of outpatients in the Department of Respiratory Medicine has increased a lot recently, with an increase of about 1/4. The patients can basically be divided into the following four categories: acute attack of respiratory disease such as chronic obstructive pulmonary disease, chronic obstructive pulmonary disease, acute exacerbation of asthma, healthy elderly people with respiratory disease due to low immunity, and healthy young people who have no underlying disease but weather Causes of cough and other respiratory symptoms.
The number of outpatients in a hospital in Hangzhou exceeded the threshold of 10,000 since November last year. Among them, the number of outpatients in respiratory departments increased by 17% in November, 49% in general pediatrics, and 65% in emergency paediatrics, compared with data from October last year. According to hospital staff, the saturation status of the respiratory medicine clinic has continued from last year to the present.
Wang Jiaoli, deputy chief physician of the Department of Respiratory Medicine at a hospital in the city, said that the abnormal weather changes in recent days, together with smog from time to time, had a large temperature difference between morning and evening and indoor and outdoor, and was a season of upper respiratory tract infections such as colds.
Reduce out and stop outdoor exercise
In life, you can start from these aspects
With the media coverage and the improvement of people's health awareness, haze has attracted more and more attention. There are reports that only 1% of the 500 largest cities in China have reached the air quality standards recommended by the World Health Organization. Mist can cause various respiratory and skin problems. In order to reduce the haze damage, many people choose to wear a mask. But not any mask can block PM2.5.
Reduce out and stop exercising outdoors. Many elderly people have the habit of getting up early in the morning, and young people prefer to exercise in the evening, such as night running. Wu Xiaohui reminded that severe haze weather is not recommended for morning exercises and evening exercises are not recommended, because these two times when the temperature is relatively low, it is easy to be stimulated by cold, and second, the air quality is poor. Better exercise time should be after 10:00 am. When the sun comes out and the air is warm, it is better to change the outdoor exercise to indoor exercise. Do not open the window when driving. Wu Xiaohui said that in addition to stopping outdoor exercise, car owners do not recommend opening windows during driving. Besides smog, car exhaust on the road is a serious type of air pollution.
Frontier residents have fewer windows. Ventilation through windows has always been considered as an effective measure to reduce indoor air pollution. Wu Xiaohui said that there is also time for ventilation in window opening and it is also recommended after the sun has come out. However, if it is a severe haze, it is impossible to open the window without opening the window. When conditions are met, placing an air purifier indoors is ideal.
Eat more lung food. In addition, Wu Xiaohui also reminded the diet should pay attention to nutritional supplements, enhance resistance, it is recommended to eat more radish, yam, horseshoe, lily and other lung food.
