Objective To investigate the application of microteaching in experimental teaching of pathophysiology. Methods A total of 120 integrated Western and Chinese medicine major students were randomly divided into experimental group (n=60) and control group (n=60). The experimental group accepted microteaching method. First, students were divided into several groups, teacher gave every group 10~15 minutes microteaching and shot the video of training process; second, students watched the video to find their deficiency with the help of teacher; and then students overcame the deficiency by repeated practice;last, the teacher gave evaluation. The control group adopted traditional method. Results The average test results of experimental group were (83.7±6.8), while the average test results of control group were ( 76 . 1 ± 7 . 2 ) , so the average test results of experimental group were higher than that of control group (P=0.000). In teaching satisfaction survey, 91.7%students were satisfied with the microteaching mode, and the satisfaction of experimental group were higher than that of control group (P=0.03). Conclusion The application of microteaching in experimental teaching of pathophysiology can improve students' experimental skills, increase students' interest in learning and improve the quality of pathophysiology teaching.

OBJECTIVETo optimize a compound prescription for treatment of liver fibrosis with an improved therapeutic effect and low toxicity.

METHODSIn rat models of liver fibrosis induced by thioacetamide (TAA), the optimized prescription was screened based on a uniform design with 2-factor 5-level table using Uniform Design 3.0 software and tested using liver content of Hyp as the screening index. To verify the efficacy of the optimized prescription, the rat models of liver fibrosis were randomized into normal control group, model group, colchicine group and optimized prescription group, and the changes of hepatic Hyp content, serum HA, ALT, AST, and ALB levels, and the pathology liver fibrosis were observed after corresponding treatments.

RESULTSThe optimized prescription, which contained 70 mg/kg glycyrrhizin and 70 mg/kg matrine, showed a significant therapeutic effect against liver fibrosis in rats (Plt;0.05), and the effect was equivalent to that of colchicine (P>0.05).

CONCLUSIONUniform design is a valuable method in prescription optimization. The optimized compound prescription of matrine and glycyrrhizin has a significant effect in inhibiting liver fibrosis.
