Witness of cross-country running in Baiyin Mountain: Before the start of running, it was covered with dark clouds and the wind was particularly strong.

  Cctv news(Reporter Wang Xiaoying) At 9: 00 am on May 22nd, the 2021 (4th) Yellow River Shilin Mountain Marathon and Rural Revitalization Healthy Run was held in the Yellow River Shilin Scenic Area. However, due to the sudden extreme weather, there were severe weather such as hail, freezing rain and strong wind, and the temperature plummeted, and some participants were unwell and lost their temperature. As of the morning of 23rd, according to the emergency rescue headquarters of the Yellow River Shilin Mountain Marathon cross-country race, the last person who lost contact in this race has been found, but there is no vital sign, which means that 21 people were killed in this incident.

  Contestant: Before the start of the race, the dark clouds were very windy.

  According to the information released by the organizer, the event is divided into three groups: healthy running, 21 km cross-country race and 100 km cross-country race. According to the information released by the organizer, the number of participants in the competition is close to 10 thousand. Among them, 172 people participated in the 100 km cross-country race. 

  A runner who has participated in the marathon many times told reporters that this time she only participated in the healthy run. The wind was particularly strong before the race, and the dark clouds were very scared. Some people at the scene only wore short-sleeved shorts. After hiking for several kilometers, she felt too cold and returned.

  Another runner who participated in the cross-country running, "Wandering in the South", also confirmed this point: on the morning of the match day, it was sunny and sunny. At the moment of going down to car ferry, the sky turned cloudy, and then the wind started, and the somatosensory temperature dropped instantly. Taking part in the 100-kilometer cross-country race, the athlete ran two kilometers to warm up before shooting, which is something that has never happened before. What’s more troublesome is that he didn’t get hot after running these two kilometers.

  At noon, there was sudden hail, freezing rain and strong wind. The runner was soaked to the skin, found a relatively sheltered place, took out a thermal blanket, wrapped it in his body, and was blown away by the wind in an instant. A contestant’s insulation blanket was directly shredded by the strong wind. Wearing gloves, ten fingers felt nothing, so he decided to quit the race and go down the mountain. On the way down the mountain, he judged that he had lost his temperature.

  According to the information released by the rescue headquarters, at about 1 noon that day, the high-altitude stage of the 100-kilometer cross-country race was 20 kilometers — 31 kilometers away, affected by sudden extreme weather, severe weather such as hail, freezing rain and strong wind occurred in the local area, and the temperature plummeted. The contestants felt unwell and lost temperature, and some of them lost contact. Then the local authorities stopped the competition and organized various forces to search and rescue the lost personnel.

  Multi-forces involved in rescue and rescue: it is difficult to search and rescue on the track. 

  After stopping the competition, local organizations such as firefighting, armed police, public security, Blue Sky Rescue Team and Gansu Ark Rescue Team participated in the search and rescue.

  Li Yuanhui, detachment leader of Baiyin Fire Rescue Detachment, told the reporter that the first batch of 25 rescuers arrived at the scene at 5 pm on the 22nd to start search and rescue, and he arrived with reinforcements at 8 pm.

  "The biggest difficulty in search and rescue is that the road is not easy to walk. Some cars can’t get in, so they can only walk. Some roads have no signal, so they are contacted by satellite phone." Li Yuanhui told reporters that the search and rescue roads are mainly from CP2 to CP4, and the stage is about 14 kilometers, which belongs to the more difficult part of the whole track. The situation is more complicated.

  Due to the complex terrain and landforms in the stage, and the temperature dropping again at night, the search and rescue is more difficult.

  "In the end, we entered the track from CP2 and CP4 respectively, and the two search and rescue teams walked in opposite directions, looking for the victims one by one." Rescuers searched and rescued twice, and finally found 21 victims by combining the list of lost persons and the location of mobile phone signals.

  The reporter noted that the Yellow River Stone Forest Scenic Area is located in the transition zone between the Loess Plateau and Tengger Desert, and the terrain is generally high in the southwest and northeast and low in the middle. Mi Jiashan and Songshan in the north-central, Hunan Mountain and Songjialiang Mountain in the south belong to the residual veins of Qilian Mountain. The route of the 100-kilometer cross-country race in this competition is the entrance of the Yellow River Stone Forest Scenic Area (starting point) — Baozigou Square — Observation deck — Changsheng village — Zhujiayao — Fujiaxian — Jinping village — Qijiaquan — Baozigou Square (end point).

  According to Li Yuanhui, the 21st victim’s sight was hidden because he fell off the cliff, so he needed to get close to see it, which led to the search and rescue at night and was not found until the daytime search and rescue on the 23rd.

  Gansu has set up an accident investigation team.

  For this competition, the reporter interviewed Mr. Zhu, who specializes in organizing cross-country competitions in China. He told the reporter that it is necessary to organize cross-country competitions, communication security, medical security and emergency plans. In terms of communication guarantee, especially in the case of poor mountain signal, the organizing Committee will set up a radio relay station, and the walkie-talkie is mandatory for each player to carry, so as to ensure that the players can communicate throughout the track. On the other hand, plans for extreme weather must be made.

  On May 23rd, the rescue headquarters held a press conference to announce the latest situation of search and rescue. Zhang Xuchen, Mayor of Baiyin City, said that the incident was a public safety incident due to sudden change of local weather, and the provincial party committee and government had set up an incident investigation team to further investigate the cause of the incident. Zhang Xuchen said: "As the organizer of the event, we feel deeply guilty and self-reproach, and express our deep condolences to the victims and express our deep condolences to the families of the victims and the injured."

Be alert! These items around you may be the culprit of cancer.

When it comes to cancer, everyone is familiar with it, even afraid! But do you know that in our life, there are also many culprits who cause cancer? Now let’s look at a case first:

Ms. Xu, who lives in Shanghai, was diagnosed with cancer last year, but what is even more frightening is that her husband, son and father all died of cancer.

What is the reason why a family has cancer and can’t escape the entanglement of cancer? The doctor conducted a lot of data analysis and found that the cause of cancer in Ms. Xu’s family turned out to be aflatoxin.

It turns out that there is a pepper tree in Aunt Xu’s home, which produces a lot of pepper every year, and Aunt Xu especially likes to eat pepper, which is indispensable for making pies, buns or cooking.

In fact, it is very difficult to store pepper. Aunt Xu will directly put away the pepper that has not been dried, so some pepper appears damp and moldy. Moreover, Aunt Xu is particularly frugal, and will continue to use moldy pepper. The doctor said that this is because the body ingested too much aflatoxin after eating moldy pepper for a long time, which induced cancer.

As early as October 2017, the World Health Organization compiled and published a list of four types of carcinogens according to their relevance to cancer. They are:

Class 1: it is a definite carcinogen for humans;

Class 2: limited evidence of carcinogenicity to humans;

Category 3: Suspicious carcinogenicity to human beings;

Class 4: substances that may not be carcinogenic to human body.

You know, there are 120 kinds of class 1 carcinogens! Today, Xiaobian has sorted out the categories that are closely related to our daily life:

01, wine and alcoholic beverages

The intermediate product of ethanol metabolism in the body is acetaldehyde, which can cause DNA damage or double-stranded breakage in cells, thus causing cancer. Ethanol is also a good solvent, and many carcinogens will be dissolved in ethanol. Some alcoholic beverages contain carcinogenic substances such as asbestos fiber, arsenic and nickel; Carcinogens such as polycyclic aromatic hydrocarbons (such as benzopyrene) may also be produced during the fermentation and distillation of wine and alcoholic beverages. Therefore, alcohol is an important risk factor for oropharyngeal cancer’s disease, laryngeal cancer, esophageal cancer, liver cancer, colorectal cancer and breast cancer.

02. Smoking

Cigarettes contain a large number of polycyclic aromatic hydrocarbons, phenolic compounds, formaldehyde and other carcinogens, which are important risk factors for lung cancer, laryngeal cancer, lip cancer, tongue cancer, oral cancer, esophageal cancer, gastric cancer, colon cancer, pancreatic cancer, bladder cancer, renal cancer and cervical cancer.

03, second-hand smoke

In the cold smoke exhaled by smokers, the tar content is twice as much as that in the hot smoke inhaled by smokers, and the benzopyrene content is twice as much.

04, processed meat (intake)

Pickled meat contains more nitrite and phosphate, while smoked meat contains polycyclic aromatic hydrocarbons (benzopyrene). It may induce a variety of cancers and is an important risk factor for colorectal cancer.

05. Chinese salted fish

A large amount of nitrite is produced in the pickling process, which is an important risk factor for inducing nasopharyngeal carcinoma.

06. Areca nut

Areca catechu has a lot of crude fiber, which will cause continuous damage to oral mucosa and lead to cancer. The alkaline substances and alkaloids contained in betel nut will destroy the cell membrane of mucosal cells and DNA of cells. It is an important risk factor for oral cancer.

07, outdoor air pollution

It is easy to cause lung cancer, and the risk of bladder cancer will also increase.

08, diesel engine exhaust

The tail gas contains hundreds of different compounds, which have been proved to be related to lung cancer and bladder cancer.

09, benzopyrene

A chemical substance found in coal tar, which is commonly found in automobile exhaust gas (especially diesel engines), smoke produced by burning tobacco and wood, and grilled food. It is a high risk factor for lung cancer, digestive tract cancer, bladder cancer and breast cancer.

10. Benzene

Paint, wallpaper, carpets, printers, automobile exhaust, synthetic fibers, building decoration materials, wood-based panel furniture and cigarette smoke all contain benzene. The products of benzene metabolism in human body will lead to the breakage and fragmentation of DNA chain and induce leukemia.

11. Formaldehyde

Ordinary people are mainly exposed to formaldehyde through artificial boards in newly renovated homes. It can cause nasopharyngeal carcinoma, neonatal malformation, childhood leukemia, Hodgkin’s lymphoma, multiple myeloma, myeloid leukemia and so on.

12, untreated or lightly treated mineral oil

Used for making hair cream, hair oil, hair wax, lipstick, facial oil, skin care fat, etc., and also used as food additive. It is a by-product of petroleum and contains a variety of hydrocarbons. Polycyclic aromatic hydrocarbons, heavy metals and other impurities may induce cancer.

13. Solar radiation

Excessive exposure, ultraviolet rays in the sun can lead to skin cancer.

14. Ionizing radiation (all types)

It mainly includes α-ray, β-ray, proton stream, neutron stream, X-ray and γ-ray. Ionizing radiation can induce various types of DNA molecular damage, thus causing cancer. May produce induced leukemia.

15. Hepatitis B virus (chronic infection)

Hepatitis B virus can cause DNA rearrangement and DNA fragment loss, and reduce the degradation ability of liver cells to other carcinogens.

16. Hepatitis C virus (chronic infection)

Virus core protein is closely related to liver cancer.

17, human papillomavirus

At present, more than 130 subtypes of DNA virus have been isolated, which are divided into high-risk and low-risk types, among which high-risk types 16 and 18 are the main types that cause cervical cancer.

18. Helicobacter pylori (infection)

Long-term settlement in the stomach will gradually destroy the gastrointestinal wall, which is a high risk factor for inducing gastric cancer.

19. Aflatoxin

It mainly exists in moldy grain, nuts and oil products. Eating food containing low concentration of aflatoxin for a long time is considered to be the main cause of liver cancer, gastric cancer and intestinal cancer.

20, estrogen-progesterone oral contraceptives (share)

It can induce liver cancer and increase the risk of breast cancer and cervical cancer.

21, painter, painter, painter, etc. (occupational exposure)

Pigments contain heavy metals such as cadmium, lead, mercury and chromium, and paints and organic solvents contain benzene and formaldehyde. Long-term exposure will increase the risk of cancer.

note:

The carcinogens mentioned above can cause some cancers, which refers to a possibility after long-term, excessive intake or contact. If you only eat a little occasionally, or touch it occasionally, don’t worry.
