Objective To study the effects of the Chinese herbal compound (Erzhiwan, Shixiaosan and combined formula) on cholestasis-induced liver fibrosis rat’s uPA. Methods Bile duct ligation method was used to make the model of cholestasis-induced liver fibrosis. One week after the operation, the rats were randomly divided into five group (model group, UDCA group, Erzhiwan group, Shixiaosan group and hefang group). Each medicine intervention group was given corresponding medicine by intragastric administration. Sham and model group were given sodium chloride with equal dosage. At the end of 4th week, all rats were sacrificed and sampled. General state of health, hepatic function (ALT, AST, ALP, TBil) and pathological histology of hepatic tissue were recorded and measured. Results Compared with the sham group, the level of ALT, AST, ALP, TBil and the degree of liver fibrosis in model group were advanced significantly. Compared with model group, three Chinese herbal compound decreased serum level of ALP, ALT and AST (P

It is one of the key problems for the development of Chinese medicine to standardize the diagnosis of syndromes. The authors mainly discuss the ideas and methods of the study of standardization of syndrome diagnosis by retrospective analysis, also put forward the following suggestions: (1) the main ideas of this study should be based on the comparison of the diseases and their relevant syndromes and the predictive diagnosis of syndromes by the effects of herbal prescription treatment; (2) they are important ways to carry out multicenter, large sample and perspective clinical trials on the basis of the investigation and study of literature, consultation of experts and retrospective case review, and following the principles of clinical epidemiology, and to use the methods of evidence-based medicine to do systemic evaluation on the criteria of syndrome diagnosis; (3) they are important sectors of the study of standardization of syndrome diagnosis to enhance the objective studies on the four diagnostic methods of traditional Chinese medicine, and to do the functional studies under the conduction of systems biology; (4) Both data excavation technology and computer intelligence are the important technique supporting this study.

Clinical effect is of great importance to traditional Chinese medicine (TCM), and the rigorous and scientific methods for clinical effect assessment should be highly stressed in the clinical research of TCM. In this article, the authors analyzed the current status of the effect assessment of TCM and proposed some measures to improve the current effect assessment of TCM, in the hope of establishing an internationally accepted system of effect assessment reflecting the superiority and characteristics of TCM therapies.

Along with the changes of disease spectrum, medical models and health concept, people pay more and more attention to the diagnostic and therapeutic approaches of traditional Chinese medicine (TCM). With the effect assessment being changed from disease-based model to patient-based model, how to scientifically and objectively explain the validity of TCM has become the premise for further development of TCM and dissemination of it throughout the world. In this article, the authors analyzed the status quo and problems of the effect assessment of TCM, and proposed some general methods for clinical effect assessment of TCM, including formulating criteria for syndrome differentiation under the guidance of TCM theories, paying attention to quality of life, proper selection of indexes for outcome assessment, application of modern clinical study methods, such as the methods of evidence-based medicine and clinical epidemiology, designing randomized controlled trials, multi-subject co-operation, strict supervision of the quality of researches, and establishment of organizations for professional training.

OBJECTIVE: To investigate the effects of Qinggan Huoxue Recipe (QGHXR), a compound Chinese herbal medicine, and its decomposed formulas Qinggan Recipe (QGR) and Huoxue Recipe (HXR) on expressions of CD14, Toll like receptor 4 (TLR(4)) and nuclear factor-kappaB (NF-kappaB) in Kupffer cells. METHODS: The isolated primary rat Kupffer cells were treated with lipopolysaccharide (LPS) for a certain period of time, a series of concentrations of drug-containing serums of QGHXR and its decomposed formulas were added, the expressions of NF-kappaB, tumor necrosis factor-alpha (TNF-alpha), CD14, and TLR(4) of the Kupffer cells were detected in different culture conditions by using Western blot, real-time reverse transcription polymerase chain reaction (RT-PCR) and ELISA methods respectively. RESULTS: QGR could down-regulate the expression of membrane receptor CD14, but the expression of NF-kappaB and TNF-alpha were not significantly decreased after QGR treatment. HXR could down-regulate the expression of membrane receptor TLR4 and inhibit the expressions of NF-kappaB and TNF-alpha. QGHXR could down regulate the expressions of membrane receptors CD14 and TLR(4) and inhibit the expressions of NF-kappaB and TNF-alpha. CONCLUSION: QGHXR can protect liver cells by down regulating the expressions of CD14, TLR(4) and NF-kappaB and inhibiting TNF-alpha expression.

OBJECTIVE: To establish a model of alcoholic liver fibrosis (ALF) in rats induced by complex factors. METHODS: Forty-seven healthy male rats were divided into three groups: normal control group (n=12), minor CCl4 group (n=12) and complex factors group (n=27). The rats in the complex factors group were fed a complex diet including alcohol, corn oil and pyrazole, and administered with intraperitoneal injection of minor CCl4 to induce ALF. During induction process, the histopathological changes of liver tissue and the values of liver-to-body weight ratio were both observed regularly. The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyltransferase (gamma-GT) in these three groups were all examined at the 12th week of the induction process. RESULTS: At the 12th week of the induction process, the model of ALF induced by complex factors was successfully established in rats, and the histopathological presentations showed alcoholic fatty liver, hepatitis and liver fibrosis in a sequence along with the induction process. The value of liver-to-body weight ratio and the serum levels of ALT, AST and gamma-GT of rats in the complex factors group were all significantly different from those in the other two groups. CONCLUSION: It is a steady and effective way to induce ALF in rats with complex diet and minor CCI4 injection.
