RESUMO
ObjectiveTo investigate the effect of Fuzheng Huayu prescription on hepatocyte extinction and regeneration in fibrotic liver and its mechanism of action in promoting hepatocyte regeneration. MethodsMice were given intraperitoneal injection of CCl4 for 6 weeks to establish a model of liver cirrhosis， and there were 10 mice in the model group， 10 in the sorafenib group， 10 in the Fuzheng Huayu prescription group， and 9 in the normal control group. Since week 4 of modeling， the mice in the Fuzheng Huayu prescription group and the sorafenib group were given the corresponding drug by gavage at a dose of 4.8 g/kg and 4 mg/kg， respectively， for three consecutive weeks， and those in the normal group and the model group were given an equal volume of sodium carboxymethyl cellulose. Serum liver function parameters were measured； the METAVIR scoring system was used to evaluate liver inflammation and fibrosis stage； Sirius Red staining and hydroxyproline （Hyp） content in liver tissue were used to evaluate collagen deposition； immunohistochemistry was used to measure the protein expression levels of type IV collagen， CD31， CD32b， Ki67， CyclinD1， glutamine synthetase， Wnt2， and HGF， and Western blot was used to measure the expression levels of Wnt2， LRP6， β-catenin， p-β-catenin， and CyclinD1 in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the model group， the Fuzheng Huayu prescription group and the sorafenib group showed the following changes： significant reductions in the serum levels of alanine aminotransferase and aspartate aminotransferase and the content of Hyp in liver tissue （all P<0.01）； a significant reduction in METAVIR score； significant reductions in the expression levels of type Ⅳ collagen and CD31 （all P<0.05） and a significant increase in the expression level of CD32b （P<0.01）； significant reductions in the number of parenchymal extinction lesions and significant increases in the expression levels of Ki67 and CyclinD1 in liver tissue （all P<0.01）； significant increases in the protein expression levels of Wnt2， LRP6， β-catenin， and CyclinD1 and a significant reduction in the protein expression level of p-β-catenin （all P<0.05）； significant increases in the number of cells stained positive for both CD32b and Wnt2. ConclusionFuzheng Huayu prescription can inhibit hepatic sinusoidal capillarization， improve the Wnt2 exocrine function of liver sinusoidal endothelial cells， activate the Wnt/β-catenin signaling pathway associated with hepatocyte regeneration， and finally reverse liver cirrhosis.
RESUMO
Objective To investigate the mechanism of Fuzheng Huayu(FZHY) decoction in the treatment of liver cancer based on network pharmacology. Methods TCMSP, BATMAN, and Drugbank databases were searched for the main chemical components and corresponding targets of FZHY, and STRING database was used to perform a PPI network analysis. Cytoscape software was used to establish a drug-disease network model and perform a network analysis, and R language was used to perform GO and KEGG enrichment analysis of targets. Results A total of 192 intersection genes between FZHY and liver cancer and 95 potential compounds were screened out, among which quercetin and luteolin were the active components with an important regulatory role. INS, IL-6, and EGFR were the key targets for the potential effect of FZHY. The GO enrichment analysis showed the involvement in various biological processes such as response to drug and response to oxygen level, and the KEGG enrichment analysis showed the involvement in the signaling pathways including apoptosis and tumor necrosis factor signaling pathways. Conclusion Based on the method of network pharmacology, this study reveals the mechanism of action of multiple targets and targets of FZHY in the treatment of liver cancer, which provides a theoretical basis for clinical and basic scientific research.
