摘要: 背景 肠易激综合征(IBS)是一种常见的复杂性功能性胃肠病,临床治疗效果欠佳。中药黄芪建中汤治疗腹泻型肠易激综合征(IBS-D)临床运用普遍且疗效肯定,但确切机制尚不十分明确,相关研究亦不多见。 目的 通过运用网络药理学和分子对接技术,初步探讨黄芪建中汤治疗IBS-D的潜在作用机制。 方法 通过TCMSP数据库获取黄芪建中汤的活性成分和潜在作用靶点,利用GeneCards、OMIM、TTD、Drug Bank、PharmGKB数据库获取IBS-D靶点,对疾病靶点和药物靶点取交集,获取黄芪建中汤治疗IBS-D的潜在靶点。使用Cytoscape软件、String数据库、Metascape数据库分别绘制"药材-活性成分-靶点"网络图、构建蛋白相互作用(PPI)网络和基因本体论(GO)功能及京都基因和基因组百科全书(KEGG)信号通路富集分析,利用AutoDock Vina和PyMOL进行分子对接和结果的可视化。 结果 最终得到黄芪建中汤活性成分123个,潜在靶点247个,IBS-D相关靶点3 486个,药物与疾病的交集靶点180个。GO功能富集分析中生物过程得到2 376个条目,分子功能得到194个条目,细胞成分得到115个条目;KEGG信号通路富集分析获得丝裂原活化蛋白激酶(MAPK)信号通路、核因子κB(NF-κB)信号通路、cAMP信号通路、雌激素信号通路等通路。分子对接显示,黄芪建中汤治疗IBS-D的主要活性成分槲皮素、山柰酚、β-谷甾醇、异鼠李素、刺芒柄花素、豆甾醇、毛蕊异黄酮、7-O-甲基-异微凸剑叶莎醇与核心蛋白丝氨酸/苏氨酸蛋白激酶1(AKT1)、细胞肿瘤抗原p53(TP53)、肿瘤坏死因子(TNF)、白介素(IL)-6、半胱氨酸天冬氨酸蛋白酶3(CASP3)、IL-1B、表皮生长因子受体(EGFR)、连环蛋白β1(CTNNB1)有较好的结合性。 结论 黄芪建中汤可能通过增强肠屏障功能、降低内脏敏感性、减轻炎性反应、调节肠道菌群起到治疗IBS-D的作用。

Abstract:

Background

Clinical treatment often achieves unsatisfactory effect for irritable bowel syndrome (IBS) , a common complex functional gastrointestinal disease. Huangqi Jianzhong Decoction is widely used for diarrhea IBS (IBS-D) , and its efficacy has been recognized, but the mechanism is unclear and relevant studies are rare.

Objective

To explore the potential mechanism of Huangqi Jianzhong Decoction in the treatment of IBS-D based on network pharmacology and molecular docking.

Methods

TCMSP database was adopted to acquire the active ingredients and corresponding targets of all herbals in Huangqi Jianzhong Decoction. And targets related to IBS-D were identified using GeneCards, OMIM, TTD, Drug Bank and PharmGKB databases. Then the intersection of herbal targets and IBS-D-related targets were selected to obtain the potential therapeutic targets of Huangqi Jianzhong Decoction for IBS-D. Cytoscape, String and Metascape were used to construct an "herbals-active ingredients-target" network map, draw the protein-protein interaction network (PPI) , and conduct genetic ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. AutoDock Vina and PyMOL were used for the visualization of molecular docking results.

Results

Finally, we obtained 123 active ingredients and 247 potential targets of Huangqi Jianzhong Decoction, 3 486 IBS-D related targets, and 180 intersected herbals targets and IBS-D-related targets. A total of 2 376 items of biological process, 194 items of molecular function and 115 items of cellular component were identified through GO enrichment analysis. Enrichment analysis of KEGG signaling pathway revealed MAPK, NF-κB, cAMP, estrogen and other related signal pathways. The molecular docking results showed that the main active ingredients of Huangqi Jianzhong Decoction in the treatment of IBS-D are quercetin, kaempferol, β-sitosterol, isorhamnetin, formononetin, stigmasterol, calycosin, 7-O-methylisomucronulatol, and they showed good binding to core proteins AKT1, TP53, TNF, IL-6, CASP3, IL-1B, EGFR and CTNNB1.

Conclusion

Therefore, we speculated that Huangqi Jianzhong Decoction may plays a role in the treatment of IBS-D by enhancing intestinal barrier function, reducing visceral hypersensitivity, reducing inflammatory response and regulating intestinal flora.
