Objective To observe the clinical effect of Jiawei Sinisan (JWSNS) on patients with alcohol liver diseases. Methods 80 patients of alcohol liver diseases were divided into two groups, JWSNS and Xiaochaihu (as control) were used respectively to observe the variation of lipoprotein and the expression of hepatic fibrosis markers. Results The symptoms and indicators of patients were improved by JWSNS. The high variation of lipoprotein and the expression of hepatic fibrosis markers were obviously detected on alcohol liver diseases patients who were treated with JWSNS (with an effectivity of 97.5%). However, patients treated with Xiaochaihu had less therapeutic effect. Conclusions JWSNS can obviously regulate the fat metabolism, resist hepatic fibrosis, and improve the symptom of patients suffering from alcohol liver diseases.
