Transcriptomic and network pharmacology approaches revealed possible mechanisms underlying the 5-fluorouracil (5-FU)-sensitizing effect of Xuan-Fu-Hua decoction treatment on liver cancer cells.

Background: Xuan-Fu-Hua decoction is a traditional Chinese medicine formula widely used for the treatment of inflammation-related disease in the lung and liver. This study aimed to investigate the effect of Xuan-Fu-Hua decoction treatment on liver cancer cells and its mechanism of action. Methods: The impact of Xuan-Fu-Hua decoction treatment on the proliferation and apoptosis of SMMC-7721 liver cancer cells with or without 5-fluorouracil (5-FU) cotreatment was determined in both in vitro and in vivo settings. Alterations in gene expression patterns in SMMC-7721 cells induced by Xuan-Fu-Hua decoction treatment were explored by transcriptomic sequencing. Effective components of Xuan-Fu-Hua decoction and their target proteins were investigated using network pharmacology approaches. Results: Xuan-Fu-Hua decoction alone did not significantly influence SMMC-7721 liver cancer cell growth, but it significantly increased the 5-Fu-induced growth inhibition and apoptosis of SMMC-7721 liver cancer cells in vitro and in vivo. Most differentially expressed genes in SMMC-7721 liver cancer cells with or without Xuan-Fu-Hua decoction treatment were enriched in cell apoptosis-related pathways. Xuan-Fu-Hua decoction treatment significantly increased the transcription levels of DDIT3, PMAIP1, and ZMAT3 genes while decreasing that of WNT4, AXIN2, NFE2L2, TGFBR1, MITF, and IGFBP3 genes. An interaction network between the effective components and their possible target proteins was constructed by predicting compound-target protein and protein-protein interactions. Gene set enrichment analysis revealed the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway as well as Bcl-2 and Mcl-1 proteins as potential regulatory targets of Xuan-Fu-Hua decoction in sensitizing SMMC-7721 cells to the cytotoxicity of 5-FU treatment. Conclusions: Xuan-Fu-Hua decoction increased the sensitivity of liver cancer cells to the cytotoxicity of 5-FU treatment, possibly by potentiating cell apoptosis and inhibiting the prosurvival machinery.

[Clinical therapy of Zisheng decoction recipe for chronic atrophic gastritis with intestinal metaplasia].

To explore the therapeutic effect and security of Zisheng decoction recipein treatment of the chronic atrophic gastritis (CAG) with intestinal metaplasia(IM). A total of 147 eligible cases were randomly divided into the traditional Chinese medicine group, Western medicine group and the combined group,47 cases in each group. Zisheng decoction recipe, famotidine, as well as Zisheng decoction recipe + famotidine were respectively given in the above three groups, with a treatment course of 30 d. The symptoms of traditional Chinese medicine, pathological score of gastric mucosa and the negative rate of Helicobacter pylori before and after treatment were observed in each group.The changes in pepsinogen Ⅰ (PGⅠ), pepsinogen Ⅱ (PGⅡ), gastrin-17 (GAS-17) and endothelin-1 (ET-1)were also detected to compare the efficient and safety indexes in the three groups. The combined group was better than the traditional Chinese medicine groupand the Western medicine group in total effective rate (P<0.05), pathological score of gastric mucosa and the negative rate of Helicobacter pylori, and serum indexes improvement (P<0.05). The improvement in TCM symptom score was more obvious in traditional Chinese medicine group and combined group than the Western medicine group (P<0.05). In the comparison ofincidence of complications,heart, liver and renal dysfunction, the traditional Chinese medicine group (2 case,4.8%)< the combined group (7 case,15.2%)
