Abstract： Objective To evaluate the efficacy of chaihu shugan san plus polyene phosphatidylcholine for non-alcoholic fatty liver disease(NAFLD).Methods Ninety patients with NAFLD were randomly divided into 3groups(each n=30):polyene phosphatidylcholine group(Group A),chaihu shugan san group(Group B),and chaihu shugan san plus polyene phosphatidylcholine group(Group C).The clinical symptom scores,biochemistry index (ALT,AST,GGT,TBIL,TC,TG,HLD-C,LDL-C),and B ultrasound examination were measured.Results There were significant differences in clinical symptom scores,ALT,AST,GGT,TBIL,TC,TG,and LDL-C between before and after treatment in the three groups(P＜0.05).After treatment,the clinical symptom scores,ALT,AST,TBIL,and LDL-C in Group C were significantly lower than those in Group A and Group B(P＜0.05).There were similar effects on TC and TG between Group B and Groop C,which were better than those in Group A(P＜0.05).Conclusion The efficacy of combined treatment of chaihu shugan san and polyene phosphatidylcholine was better than that of merely chaihu shugan san or tiopronin.
