ABSTRACT
BACKGROUND: Wumei Wan (WMW) has been used to address digestive disorder for centuries in traditional Chinese medicine. Previous studies have demonstrated its anti-colitis efficacy, but the underlying mechanism of its action remains to be further clarified. PURPOSE: To investigate the underlying mechanisms of WMW in the treatment of chronic ulcerative colitis (UC) through network pharmacology and experimental validation. METHODS: Traditional Chinese Medicine Systems Pharmacology (TCMSP) platform were used to identify the ingredients and potential targets of WMW. The microarray gene data GSE75214 datasets from GEO database was used to define UC-associated targets. Cytoscape3.7.2 was employed to construct the protein-protein interaction (PPI) network and compounds-disease targets network. GO enrichment analysis and KEGG pathway analysis were performed by R software for functional annotation. UPLC-TOF-MS/MS method was used to quantitatively analyze the active ingredients of WMW. For experimental validation, three cycles of 2% dextran sulfate sodium salt (DSS) were used to construct chronic colitis model. The hub targets and signal pathway were detected by qPCR, ELISA, western blotting , immunohistochemical and immunofluorescence. RESULTS: Through network analysis, 104 active ingredients were obtained from WMW, and 47 of these ingredients had potential targets for UC. A total of 41 potential targets of WMW and 13 hub targets were identified. KEGG analysis showed that WMW involved in advanced glycation end products-receptor of advanced glycation end products (AGE-RAGE) signaling pathway. Taxifolin, rutaecarpine, kaempferol, quercetin, and luteolin of WMW were the more highly predictive components related to the AGE-RAGE signaling pathway. In vivo validation, WMW improved DSS-induced colitis, reduced the expression of inflammatory cytokines and chemokines. Notably, it significantly decreased the mRNA expression of Spp1, Serpine1, Mmp2, Mmp9, Ptgs2, Nos2, Kdr and Icam1, which were associated with angiogenesis. In addition, we confirmed WMW inhibited RAGE expression and diminished DSS-induced epithelial barrier alterations CONCLUSION: Our results initially demonstrated the effective components and the strong anti-angiogenic activity of WMW in experimental chronic colitis. Sufficient evidence of the satisfactory anti-colitis action of WMW was verified in this study, suggesting its potential as a quite prospective agent for the therapy of UC.

Several clinical trials have reported that patients with cancer cachexia can benefit from n-3 polyunsaturated fatty acids (n-3 PUFAs) supplements; however, the results have been conflicting. This systematic review and meta-analysis aimed to evaluate the effect of n-3 PUFAs on cancer cachexia. A search of the PubMed, Embase, and Cochrane Library databases was performed to identify the included randomized controlled trials. Trials including patients with cancer cachexia who were administered a course of n-3 PUFAs were included. A meta-analysis on body weight, lean body weight, proinflammatory factors, quality of life, and median duration of survival was conducted. A total of 12 randomized controlled trials with 1184 patients were included. No effect on body weight (standard mean difference [SMD], 0.10; 95% CI, -0.06 to 0.26; P = .236), lean body weight (SMD, -0.17; 95% CI, -0.36 to 0.03, P = .095), or proinflammatory factors (interleukin-6: SMD, 0.31; 95% CI, -0.14 to 0.75; P = .18; tumor necrosis factor-α: SMD, -0.85; 95% CI, -2.39 to 0.69; P = .28) was observed. The use of n-3 PUFAs was associated with a significant improvement in quality of life (SMD, 0.70; 95% CI, 0.01-1.40; P = .048) and median duration of survival (median survival ratio, 1.10; 95% CI, 1.02-1.19; P = .014). For patients with cancer cachexia, our meta-analysis indicated that n-3 PUFAs improved quality of life and survival, but not body weight.

Clinical trials have reported that a four-oil intravenous lipid emulsion (SMOFlipid) play a positive role in immune function, but showed inconsistent outcomes compared to other lipid emulsions. A systematic review and meta-analysis was conducted to evaluate the effect of SMOFlipid on liver function, triglycerides (TG), inflammatory markers, and clinical outcomes in hospitalized adults after short-term use compared to others. A search of the PubMed, Medline, Embase, China National Knowledge Infrastructure, and Wanfang databases was performed to identify the included randomized controlled trials. Trials with adults who were administrated a short-term course of SMOFlipid were included. A meta-analysis on liver function markers, TG, inflammatory markers, and clinical outcomes was conducted. A total of 18 randomized controlled trials with 1188 patients were included. Compared to other lipid emulsions, SMOFlipid was associated with a significant reduction in ALT, AST, γ-glutamyltransferase, total bilirubin, TG, C-reactive protein and length of hospital stay. No effect on serum interleukin-6 levels or adverse events were observed. For adult patients, our meta-analysis indicated that SMOFlipid may be beneficial to the liver and prone to prevent hyperlipidemia. The SMOFlipid also shortened length of hospital stay.

Gut microbiota is a complex microecosystem, which is called the second genome of the human body. Herbal medicine can balance tumor-suppressing bacteria and tumor-promoting bacteria and exert its anti-cancer effect by regulating gut microbiota. Traditional Chinese medicine (TCM) has a history of thousands of years in prevention and treatment of diseases in China. In recent decades, TCM has been shown to have an obvious advantage in prolonging the survival time and improving the living quality of patients with cancer. Notably, gut microbiota has become a new pathway to understanding TCM. In this review, we will focus on gut microbiota and tumor progression, especially the diversity, functionality and metabolites of gut microbiota affected by TCM in various cancer. We will also discuss the potential mechanism of gut microbiota for exploring TCM in anti-cancer effect. This article aims to comprehensively review the anti-cancer research of TCM by regulating gut microbiota, and address future perspectives and challenges of gut microbiota in TCM intervention for cancer.
