Methods: The main targets of the active ingredients of RERR and SP were filtered based on the traditional Chinese medicine system pharmacology analysis platform. Cytoscape 3.2.1 was applied to build the ingredient-target network of RERR and SP for AIO. Results: Fifteen active components were predicted from the RERR and SP herb pair, such as aloe-emodin, catechin, rhein, gibberellin (GA) 119, GA120 and GA121. These components were applied to 59 targets mainly involved in many biological processes such as signal transduction, anti-apoptosis, and inflammatory response involved in activating the immune effect. Conclusion: This study proposes the system pharmacology method and identifies the potent combination therapeutic mechanism of RERR and SP for AIO. This strategy will provide a new insight to the study of herb combinations.展开更多

METHODS: Samples of different ratios of Dahuang(Radix et Rhizoma Rhei Palnati, DH) to Taoren(Semen Persicae, TR)(Group A 1∶1, B 2∶3, C 3∶2) were analyzed based on gas chromatography time-of-flight mass spectrometry untargeted metabolomics technique. RESULTS: A total of 240 primary metabolites were detected. Forty-one differential metabolites involved nine differential metabolic pathways, of which four were closely related to the efficacy of DT in the treatment of heat and blood stasis syndrome. These pathways included the biosynthesis of amino acid(phenylalanine tyrosine and tryptophan), flavonoids, unsaturated fatty acids, and the glycolysis/glycogenesis pathway. CONCLUSION: There are significant differences in the efficacy of different ratios of DT drugs, and their optimal ratio for the treatment of heat and blood stasis syndrome should be 1∶1.展开更多

Methods: Forty-four patients were treated for 3 months, the clinical and pathological effects were observed. Results: Patients were improved clinically.Pathological examination on liver biopsy of 6 patients also showed improvement in of capillarization of sinusoid,which mainly manifested by reduction of enlarged interhepatocellular spaces and collagen fiber in it, increase of lipid droplets within fat-storing cells (FSC), and decrease of proliferation of Kupffer cells. Conclusion: The combined treatment used could reverse the capillarization of sinusoid, and the mechanism might be related with its inhibition on activity and function of FSC.展开更多
