Background: In less than a year, COVID-19 has swept the world and continued, too, seriously threatening the safety of all mankind, and caused great social panic and global economic and financial crisis. At the beginning, the epidemic was first diagnosed in China and the epidemic was severe. Under the strong command of the highest level of the Chinese government, the whole Chinese people united as one, and achieved initial results in the struggle against COVID-19 with scientific prevention and control. Objective: Summarizing China’s experience and lessons in combating the epidemic is undoubtedly very beneficial to the people of the world in jointly combating the impact of the COVID-19 epidemic. Measures: The article shows the imminent Chinese experience in controlling the spread of SARS-CoV-2. It details the lines of action and the measures taken to control this epidemic in the country where the population is quite large. The most important experience is: strong organizational leadership, enhanced cooperation with the WHO, the establishment of a national anti-epidemic headquarters, responsible for the command and control of human, financial and material resources throughout the country, and local officials at all levels in the front line of the epidemic, Heart to heart with the people, breathing together and sharing a common destiny. Prevention is the first, prevention and treatment are combined. All measures were taken to control the source of infection, cut off the spread and protect susceptible people. Conclusion: As long as the people of the world unite, make scientific decisions and learn from the successful experience of countries around the world, especially the China’s experience, combine the national conditions of each country, and use the wisdom of all man-kind to deal with the common enemy SARS-CoV-2 and COVID-19, we can definitely win this people’s war against the disease.

The calpain system is ubiquitous in cells, mainly comprising calpains and calpain inhibitors, and is a widespread calcium-dependent cysteine protease in organisms that is involved in many cellular processes such as muscle degradation in vivo and affects the tenderness of meat after animal slaughter. The study found 128 DEGs that probably regulated tenderness traits were selected from 16 significantly enriched GO terms by transcriptome sequencing analysis, and found that the developmental changes in the expression levels of the CAPN1 gene in the pectoral and leg muscles were significantly positively correlated ( P <0.05) with the cumulative growth values of live weight and comb weight. The developmental changes in the expression levels of the CAST gene in the pectoral and leg muscles were not significantly correlated with the cumulative growth values of live weight and comb weight. Our results helped demonstrate the potential molecular mechanisms of tenderness in chickens and provide valuable information for chicken breeding.
