g mountain disease is called poor disease, also called "desperate disease".
Once in 16 provinces, Heilongjiang, Jilin, Liaoning and 124 million people were troubled by Keshan disease. In 1935, Keshan disease broke out in Keshan County, Heilongjiang, and was named after it. At that time, a large number of farmers died suddenly in some rural areas. The disease occurred quickly and died within a few hours and one or two days. Especially in the cold winter, 30 to 50 people died in a village .
The hearts of these deceased people are 2 to 3 times larger than those of ordinary people, which is a typical manifestation of myocardial necrosis. At that time, no one knew what caused such a terrifying disease.
1953, , then associate professor of Hayi Medical University, was ordered to rush to Keshan County and launched a battle to end Keshan disease.
1. Use tofu to cure the "desperate disease", the poor disease caused by selenium deficiency
. The cruelty of witnessing Keshan disease for the first time
. Yu Weihan, who just arrived in the ward, did not know about Keshan disease, and there was no reference information. One day, a 14-year-old boy fell ill from Keshan on the outskirts of Bei'an County. His parents and sister died of Keshan's illness. Yu Weihan wrapped his coat in the boy and rushed to a hospital in Bei'an County for treatment.
Although he had been rescued for more than ten hours, the boy passed away. Before his death, the boy said to him: "I am dead, just bury me at the feet of my mother!" This scene made Yu Weihan's heart cut.
The death of the patient hurt Yu Weihan's heart heavily. Until his later years, his bookshelf still showed the heart specimens of two deceased patients and 124 heart pathological sections. He said that letting oneself look at the heart of the deceased every day is to make one's soul restless and must end Keshan's disease.
. Overcome all kinds of difficulties and risks, improve the survival rate of patients
in Weihan day and night to diagnose, rescue, and treat, analyze and analyze, and constantly summarize the experience of Keshan disease. In 1964, Yu Weihan established a Keshan Disease Prevention and Control Observation Station in Fuyu County, Heilongjiang Province, and conducted a comprehensive study of 16,000 people for 22 years, and obtained countless precious first-hand information on .
Later, Yu Weihan tried to use subhibernation and appropriate fluid rehydration therapy to treat patients with acute Keshan disease. increased the cure rate of acute Keshan disease from 30% to 95%, greatly increasing the treatment rate of acute Keshan disease.
. Strip the silk and peel the cocoon and find the real murderer of Keshan disease
After several years of research, Yu Weihan discovered that Keshan disease is caused by a long-term single diet. believes that selenium is closely related to Keshan disease , so he began to pay attention to the diet structure of the ward.
Yu Weihan began to advocate that people in the ward eat soybeans and soy products to improve the dietary structure. In order to make everyone eat tofu, he sent tofu and soy milk to the villagers from door to door, and thus got the nickname "Tofu Professor".
Yu Weihan used decades to eliminate an epidemic. In people's eyes, he was like a great person like a god. With the efforts of countless medical scholars like Yu Weihan who are committed to studying and conquering Keshan disease, Keshan disease has rarely appeared. In 1997, Yu Weihan was elected as an academician of the Chinese Academy of Engineering, and died of illness in 2010 at the age of 88.
2. Selenium - a trace element that is essential for the human body, a helper for protecting the heart against cancer
g Shan disease is an unknown endemic cardiomyopathy. The mortality rate is very high during acute attacks. Patients will experience symptoms such as shock , nausea, circulatory failure, spray vomiting, asthma , and can spit out bile and gastric juice, so it is often called "spitting yellow water disease". The distribution of Keshan disease is obviously regional, mainly distributed in a low-selenium area from northeast to southwest in my country.
Selenium is a necessary trace element in the human body, but the human body cannot synthesize selenium independently and can only supplement it from food.So, what are the main effects of selenium on the human body?
, protecting the heart
The role of selenium in protecting the heart was first discovered in the study of Keshan disease. At present, there is a large amount of evidence to show the important role of selenium and its selenite protein in protecting the cardiovascular system , which is mainly related to the antioxidant properties of selenium. The increase in the activity of selenase can enhance the body's antioxidant ability, promptly eliminate harmful free radicals in the body, protect the structural and functional integrity of the cell membrane, and thus play a role in preventing and treating cardiovascular diseases.
. Fighting cancer
As a trace element, selenium also has many advantages in fighting cancer, and it has the ability to protect healthy cells and selectively attack cancer cells.
However, the effect of selenium on cancer cells is related to its concentration. High concentration of selenium in can play a cytotoxic role in cancer cells. Excessive selenium can induce apoptosis of cancer cells, but low concentration of selenium may promote the growth of cancer cells. Therefore, selenium is closely related to the dose in terms of fighting cancer, but this dose remains to be determined.
3. How should we supplement selenium?
According to the reference standards for dietary nutrients for Chinese residents, The average daily demand for selenium for adults is 50 micrograms, and the recommended intake is 60~400 micrograms .
However, it should be noted that excessive selenium supplementation is also harmful. Because the range between the nutritional active dose and the toxic dose of selenium is relatively narrow, if the intake of is excessive, it is easy to cause selenium poisoning , resulting in symptoms such as nails and hair loss, neurological diseases and skin damage. In normal times, we can mainly replenish selenium through our diet. The following are all foods rich in selenium:
, sea fish
Deep-sea fish are the foods with the highest natural selenium content. A sea fish weighing half a pound usually contains about 50 micrograms of selenium.
, egg
will add selenium to the feed for raising chickens, so eggs are also selenium-rich foods. An egg contains about 5 to 10 micrograms of selenium.
Beef, pork and other meats are also foods with high selenium content. The 2 liang of meat contains about 10 micrograms of selenium.
, beans
Many beans and soy products are rich in selenium, such as safflower beans (19.05), tiger skin kidney beans (9.75), flower pea (9.72), soybeans (6.16), red kidney beans (4.61), broad beans (4.29), mung beans (4.28), peanut kernels (3.94), northern tofu (2.62), southern tofu (1.55).
Generally speaking, as long as normal people are not biased or picky about food, try to intake a variety of foods, pay attention to balanced nutrition, and appropriately eat livestock, poultry, meat, eggs and other foods. Inland people can also appropriately eat seafood or selenium-rich foods, so that they can usually obtain enough selenium for the human body.
Selenium is very important for human health, but it does not mean that the more you supplement, the better. Normal people can scientifically obtain selenium from food. #绿子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子子� The great doctor of the common people in the Wei and Han Dynasty》.
