基于网络药理学探讨当归–白芍药对治疗儿童抽动障碍的作用机制研究

To Explore the Mechanism of Angelica Sinensis and Radix Paeoniae Alba in the Treatment of Tic Disorders in Children Based on Network Pharmacology

摘要: 目的：运用网络药理学方法探讨当归、白芍治疗小儿抽动障碍(TD)的作用靶点及相关信号通路，以明确其作用机制。方法：在TCMSP数据库中检索当归、白芍化学成分并筛选作用靶点，并检索相关文献进行补充；从GeneCards、OMIM数据库检索与TD相关的疾病靶点，利用Cytoscape 3.9.1软件构建化合物–靶点网络，筛选核心网络后进行GO功能和KEGG通路富集分析。结果：共筛选出当归活性成分2种，作用靶点69个；白芍活性成分13种，作用靶点123个。活性成分靶点与TD疾病靶点的交集基因共38项。PPI网络共包含节点37个、318条边。GO分析结果显示，上述交集基因的生物进程主要包括对外刺激反应、信号传导、RNA聚合酶Ⅱ对转录的正向调节等；细胞组成包括细胞质、细胞膜、突触神经元等；分子功能包括蛋白质结合、酶结合位点、相同的蛋白质结合等。KEGG分析结果显示，信号通路主要涉及神经活性配体–受体相互作用、胆碱能突触、c型凝集素受体信号通路、钙离子信号通路等。结论：本研究初步验证了当归–白芍治疗TD的药理学作用机制，为进一步从细胞生物学层面验证其作用机制奠定了基础。

Abstract: Objective: To investigate the therapeutic targets and related signaling pathways of Angelica sinensis and Radix paeoniae alba in the treatment of tic disorders (TD) in children using network pharmacology, so as to clarify their mechanisms of action. Methods: The chemical constituents of Angelica sinensis and Radix paeoniae alba were retrieved from the TCMSP database to screen their targets, and the relevant literature was searched. The disease targets related to TD were searched from GeneCards and OMIM databases. Cytoscape 3.9.1 software was used to construct the compent-target network, and the core network was screened for GO function and KEGG pathway enrichment analysis. Results: A total of 2 active ingredients of Angelica sinensis were screened out, and 69 targets were identified. There were 13 active components of Paeony with 123 targets. There were 38 intersection genes between active ingredient targets and TD disease targets. The PPI network included 37 nodes and 318 edges. GO analysis showed that the biological processes of these intersection genes mainly included response to external stimulation, signal transduction, and positive regulation of transcription by RNA polymerase II. The cell composition included cytoplasm, cell membrane, projection neuron, etc. Molecular functions include protein binding, enzyme binding sites, identical protein binding, etc. KEGG analysis showed that the signaling pathways were mainly involved in neuroactive ligand-receptor interaction, cholinergic synapse, C-type lectin receptor signaling pathway, calcium ion signaling pathway, etc. Conclusions: This study preliminarily verified the pharmacological mechanism of Angelica sinensis and Paeony in the treatment of TD, which laid a foundation for further verification of its action mechanism at the cell biological level.
