目的] 运用网络药理学探讨桑麻止咳汤治疗西北燥证兼慢性支气管炎的作用机制。方法] 利用多个数据库获取药物有效成分、疾病靶点，取两者交集基因。通过STRING和DAVID数据库构建蛋白相互作用网络和富集分析，运用Cytoscape建立中药-成分-疾病靶点网络。运用Autodock Vina软件进行分子对接验证。结果] 筛选得到桑麻止咳汤活性成分287个，药物靶点1 147个，疾病靶点213个。基因本体（GO）富集分析得到93个条目，京都基目与基因组百科（KEGG）通路富集分析确立了49条相关通路。分子对接结果显示药物主要活性成分与核心靶点结合活性良好。结论] 研究发现，桑麻止咳汤可能通过白细胞介素-17（IL-17）和晚期糖基化终产物及其受体（AGE-RAGE）等信号通路影响肿瘤坏死因子（TNF）、基质金属蛋白酶（MMP9）、白蛋白（ALB）和MMP1等靶蛋白的表达，槲皮素、棕榈酸、山奈酚和芹菜素可能是其发挥多靶点和多途径治疗西北燥证兼慢性支气管炎的主要成分。

Using network pharmacology to explore the mechanism of Sangma Zhike Decoction in treating northwest dryness syndrome and chronic bronchitis

Objective] To explore the mechanism of Sangma Zhike Decoction in the treatment of northwest dryness syndrome and chronic bronchitis by using network pharmacology. Methods] Multiple databases were used to obtain the effective components of drugs and disease targets,and the intersection genes of the two were obtained. The protein-protein interaction network and enrichment analysis were constructed by STRING and DAVID databases,and the traditional Chinese medicine-component-disease target network was established by Cytoscape. Autodock Vina software is used for molecular docking verification. Results] The 287 active components,1 147 drug targets and 213 disease targets of Sangma Zhike Decoction were screened. The GO enrichment analysis obtained 93 entries,and the KEGG pathway enrichment analysis established 49 related pathways. Molecular docking results showed that the main active components of the drug had good binding activity with the core target. Conclusion] The study found that Sangma Zhike Decoction may affect the expression of target proteins such as TNF,MMP9,ALB and MMP1 through signal pathways such as IL-17 and AGE-RAGE,and quercetin,palmitic acid,kaempferol and apigenin may be the main components of its multi-target and multi-way treatment of northwest dryness syndrome and chronic bronchitis.
