Wild boars broke into a milk tea shop? See the scientific interpretation of the hot topics of the week

1. Wild boars are planned to be removed from the list of “three-have” terrestrial wild animals

Have you ever eaten pork or seen a pig run? Pigs are no strangers to us all. But do we know enough about the troubles caused by wild boars in China?

In recent months, conflicts between wild boars and humans have occurred frequently. In Nanjing alone, at least five cases of wild boars hitting cars have occurred since October. In fact, the forestry, ecological environment and other relevant departments of Jiangsu Province set up eight monitoring areas in Nanjing as early as 2019, and found that there were wild boars in each area, and the population was increasing.

In Tongjiang County, Sichuan Province, wild boars have become rampant, reaching more than 20,000, often destroying crops and leaving villagers with nothing to harvest. Staff and professional hunting teams hunted eight wild boars in November, and two hunting dogs were bitten to death in the process. It is very difficult to prevent and control the harm caused by wild boars. Currently, nine provinces have introduced relevant damage compensation measures, and 14 provinces have launched prevention and control pilot projects.

On December 10, 2021, the National Forestry and Grassland Administration issued a draft for soliciting public opinions on the "List of Terrestrial Wildlife with Important Ecological, Scientific and Social Values ​​(Draft)". In this draft, wild boars, which were listed in 2000, have been deleted.

If the opinion is passed, wild boars will no longer be "three-protected" wild animals and will no longer be protected by the state in law. However, this does not mean that wild boars can be hunted at will. They are still protected by hunting bans and hunting bans, and they still have ecological value. They are an important link in the food chain and play an important role in regional ecological balance.

2. New breakthrough! The "culprit" of lupus erythematosus has surfaced!

On December 10, Chinese and foreign research teams from Shanghai Jiao Tong University School of Medicine jointly published their latest research results in the Journal of Experimental Medicine, discovering that P2RY8 protein expression or functional defects are important risk factors for systemic lupus erythematosus (SLE).

Systemic lupus erythematosus is a chronic systemic autoimmune disease that can affect multiple organs throughout the body and can be life-threatening in severe cases. The pathogenesis of the disease is still unclear and there is still a lack of good cures. A large number of studies have shown that genetic and environmental factors are closely related to the occurrence of the disease.

This time, the research team collaborated to identify three rare missense mutations of the P2RY8 gene. These mutations interfere with the normal expression of the P2RY8 protein, and two of the variants can enhance the activation and migration of B cells. The experiment also found that although some SLE patients do not carry P2RY8 gene mutations, they still show low levels of expression of P2RY8 protein. In terms of principle and mechanism, the exploration of disease susceptibility sites related to genetic variations such as P2RY8 somatic mutations will help reveal the pathogenesis of SLE and develop new prevention and treatment methods.

3. Exercise can really fight cancer!

Do you usually like to stay at home and don’t like to exercise? Recently, new research shows that exercise can inhibit tumors and prevent cancer!

The researchers asked 10 prostate cancer patients with an average age of 73 to participate in a 12-week exercise intervention, with a total of 300 minutes of exercise per week. This included resistance training for major muscle groups, 1 to 4 sets each time, 6 to 12 repetitions at maximum intensity, about 1 hour each time, and 5 to 10 minutes of aerobic warm-up and relaxation.

The researchers found that the blood after exercise had a significant inhibitory effect on the growth of these cancer cells, and long-term exercise can create an environment in the body that inhibits cancer. Although only prostate cancer patients have been studied so far, the myokines released into the blood by exercise should be effective against all forms of cancer.
