【摘要】 目的：在网络药理学和实验验证的基础上，探讨补中益气丸在治疗溃疡性结肠炎中的作用机制。方法：采用UPLC-QE-MS对补中益气丸进行定性分析。从GeneCards中检索到化学成分和疾病的靶点，然后构建蛋白质-蛋白质相互作用网络（protein-protein interaction networks,PPI），从GO term分析和KEGG通路分析中筛选核心靶点，建立溃疡性结肠炎小鼠模型，验证其关键靶点。结果：共筛选出123个交集靶点和24个核心靶点，共鉴定出补中益气丸的41种化学成分。KEGG分析和PPI网络分析表明，补中益气丸可能通过Akt、PI3K等途径在溃疡性结肠炎的治疗中发挥作用。动物实验结果显示，补中益气丸可显著改善溃疡性结肠炎的症状，降低血清中IL-6和TNF-α水平（P<0.01），抑制Akt-PI3K信号通路，降低PI3K蛋白表达（P<0.05）。结论：补中益气丸可能通过抑制AktPI3K信号通路，抑制PI3K表达，降低IL-6和TNF-α水平，在溃疡性结肠炎中发挥作用。更多还原

【Abstract】 AIM:To explore the anti-ulcerative colitis mechanism of Buzhongyiqi pills based on the network pharmacology and experimental verification. METHODS: UPLC-QE-MS was used for qualitative analysis of Buzhongyiqi pills. Targets of the chemistry constituents and the disease were retrieved from GeneCards. Then the protein-protein interaction(PPI) network was constructed and core targets were screened for GO term enrichment and KEGG pathway enrichment. Ulcerative colitis mouse model was established to verify the key targets. RESULTS: A total of 41 constituents migrating of Buzhongyiqi pills were identified. A total of 123common targets of the constituents and the disease and 24 core targets were screened out.KEGG enrichment and PPI network analysis showed that Buzhongyiqi pills may play a role in the treatment of ulcerative colitis through Akt, PI3K and other pathways. Furthermore, the results of animal experiments showed that Buzhongyiqi pills could significantly improve the depression behaviors of ulcerative colitis, reduce the levels of IL-6 and TNF-αin serum, inhibition Akt/PI3K signaling, and reduce the protein expression of PI3K. CONCLUSION: Buzhongyiqi pills may play a role in the treatment of ulcerative colitis by inhibition Akt/PI3K signaling pathway, and inhibiting PI3K and reduce the levels of IL-6 and TNF-α in the mice.更多还原
