[Explanation] The laboratory animal room refers to a building suitable for feeding and breeding laboratory animals. Such buildings have specific environmental requirements and experimental methods to ensure the quality of animals and the accuracy and reliability of experimental research. On July 7, the reporter visited the Animal Laboratory of Beijing Sport University.
The experimental animals raised in the animal laboratory of Beijing Sport University belong to a specific pathogen-free level. The feeding environment requires a barrier environment, so it is necessary to ensure the cleanliness of the laboratory.

Because our animal laboratory is all rodents, it is at least above the barrier environment and isolation environment in national laws and regulations, so in this environment, we must ensure the cleanliness of the air inside, so it is the three Filter, and then there are some pressure requirements, so its entire environment is clean.

When we enter the animal room, we need to change the protective clothing, we need to wear masks and gloves, and then the items we enter need to be sterilized through the delivery window or sterilized. Our personnel mainly flow in one direction. After changing into protective clothing, they are relatively clean, enter the barrier environment inside, and then come out through the pollution buffer room.
【Explanation】Different from the animal laboratories of other ordinary colleges and universities, the animal laboratories of Beijing University of Physical Education are more focused on the research of animal sports, and will carry out training programs such as weight-bearing swimming and weight-bearing running on experimental animals.

After exercising in various ways to detect changes in its physiological and biochemical indicators, or to look at changes in some of its proteins or genes, to see if it will change in the human body. If a certain protein is in Significant changes have occurred during exercise, so does this protein also change during (human) exercise? It may also be applied to the application of drugs.
【Explanation】During the New Coronary Pneumonia epidemic, due to the fact that the relevant staff cannot return to work normally, the management staff of the animal laboratory has also undertaken a lot of additional work. Because the laboratory requires constant temperature and humidity, and has a certain pressure difference with the outside atmosphere, Hua Weicheng will undertake to replace the filter for the air conditioner regularly.

The school is relatively closed management, and then some staff are not easy to come in. Some equipment maintenance originally found some engineers to come, now I have to come (maintenance). To maintain the pressure difference in the animal room, I need to replace the air conditioner filter regularly. I need to do this.
【Explanation】Hua Weicheng said that although the epidemic has brought some challenges to the management of animal laboratories, as long as you are patient and careful, the "barrier" for experimental animals will continue to build.
