Abstract:
Objective:To analyze the mechanism of Qiwei Qinggan Powder in the treatment of hepatic fibrosis by animal experiment and network pharmacology.Methods:A total of 50 rats were randomly divided into blank group, model group and low, medium and high dose of Qiwei Qinggan Powder groups with 10 rats in each group. Except the blank group, other groups were gavaged with 50% carbon tetrachloride peanut oil solution to prepare liver fibrosis model. Rats of low, medium and high dose of Qiwei Qinggan Powder groups were gavaged with 135, 270 and 405 mg/kg Qiwei Qinggan Powder 0.5% CMC-Na solution once a day for 10 weeks. The contents of serum GPT and GOT were detected by Wright's method, the content of ALP was detected by visible light colorimetry method, and the liver structure was observed by HE staining and Masson staining. The mRNA and protein expressions of α-SMA and collagen Ⅰ were detected by Q-PCR and Western blot from hepatic stellate cells. Flow Cytometry was used to detect the effect of Qiwei Qinggan Powder on hepatic stellate cells apoptosis. By searching for Traditional Chinese Medicines Integrated Database, Traditional Chinese Medicine Systems Pharmacology Database as well as literature retrieval, the active chemical components and targets of Qiwei Qinggan Powder were obtained. The targets of hepatic fibrosis were obtainable through OMIM and PubMed. By using Cytoscape 3.7.2, the Medicine-active components-Gene-Disease network was constructed. Obtaining Protein-Protein Interaction Networks screens the central target by using STRING, and using R language to retrieve Bioconductor online GO function enrichment and KEGG pathway enrichment analysis were carried out on the platform.Results:Compared with the model group, the levels of GFT, GOT and ALP in high, medium and low dose groups were decreased ( P<0.01). Compared with the control group, the mRNA levels of α- SMA (0.24 ± 0.12, 0.25 ± 0.12, 0.41 ± 0.15 vs. 1.00 ± 0.00), collagenⅠ (0.64 ± 0.24, 0.33 ± 0.13, 0.28 ± 0.11 vs. 1.00 ± 0.00)was decreased ( P<0.05 or P<0.01) of serum containing low, medium and high dose groups of Qiwei Qinggan Powder, and α-SMA (0.03 ± 0.01, 0.01 ± 0.00, 0.01 ± 0.00 vs. 0.04 ± 0.00), collagenⅠ (0.08 ± 0.01, 0.10 ± 0.01, 0.13 ± 0.01 vs. 0.18 ± 0.01) mRNA levels was decreased of serum containing low, medium and high dose groups ( P<0.01). A total of 35 active components, 196 targets, 3 740 disease targets and 170 disease common targets were screened out. 159 items were obtained by GO enrichment analysis; 43 signal pathways were obtained by KEGG enrichment analysis. Conclusion:Qiwei Qinggan Powder can promote HSCs apoptosis and treat HF through multi-component, multi-target and multi-channel therapy.
