It puts forwards the hypothesis of disease curtailment efficacy,viewing that it may explain the TCM medication rule and the mechanism of TCM compatibility improving cure effect;taking gastric ulcer as pathological model,Lizhong Decoction as object,it makes split formula experiment to test its existence of disease curtailment effect,exposing the scientific and available hypothesis.

Objective:To probe the effect of Alisol Monoacetate A and Alisol Monoacetate B on the synthesis and metabolism of cholesterol in HepG2 cell line.Methods:Controlled with Lipitor,different concentration of Alisol Monoacetate A and B were added to HepG2 cell line model,then collected and detected the contents of cholesterol in the cell lysate and cultured medium after 24h's cultivation.Results:The cytotoxicity of Alisol Monoacetate A and B appeared at least 10% when its concentration was higher than 10?M,more than 70% when its concentration was 50?M.The contents of cholesterol in HepG2 cell lysate increased from 24.4,26.7,32.3 and 38.3?g/mg protein corresponding with the concentration of 0?M,3?M,10?M and 20?M respectively,which showed the positive dose-effect relationship.However,the contents of cholesterol in the cultured medium manifested no difference.Conclusion:Alisol Monoacetate A and B could enhance the metabolic activity of mitochondria and increase the synthesis of cholesterol in HepG2 cell line.
