Objective Application of Case-based teaching method (CTM) in the class of Experimental Animal Quality Control aims to break the traditional teacher-centered and textbookcentered teaching model,to invoke students' interest and creativity by integrating practice and theory,and to cultivate their capacity in identifying,analyzing and solving problems.Methods According to different requirements of teaching contents,students were organized to discuss practical cases about quality control of experimental animals through problem-centered learning style.Results Students' capacity was enhanced in terms of problem solving with acquired knowledge,and the ability to pursue new knowledge,the intriguing and vivid cases stimulated students' interest,activated classroom atmosphere,and helped improve teaching efficiency.Conclusion Experimental animal quality control is a complicated system; Case-based teaching method leads to higher efficacy of the course of Experimental Animal Quality Control.

In recent years,many kinds of animal models of human diseases with different genetic background were developed.Some were established in China,others were imported from abroad.Precious were these animal models,their biological features could be lost for various reasons,for instance,reverse from mutation,lost of modified or constructed gene,etc.This study provided some suggestions for scientific management of the animal models to in terms of quarantine inspection,specific feeding method and methods to maintain gene stability,so as to preserve their biological features.
