目的 基于网络药理学及分子对接技术探究土茯苓治疗痛风性关节炎的作用机制。方法 通过检索TCMIP、TCMSP、HIT、NPACT数据库筛选土茯苓的活性成分及其作用靶点，并与痛风性关节炎疾病靶点进行交集，构建“药物–活性成分–靶点–疾病”调控网络图和蛋白相互作用（PPI）网络，进行基因本体（GO）功能和京都基因与基因组百科全书（KEGG）通路富集分析。选取关键活性成分与核心靶点蛋白进行分子对接验证，计算结合能并可视化对接构象。结果 筛选得到土茯苓的15个活性成分及206个作用靶点，与痛风性关节炎的277个靶点取交集后获得28个共有靶点。构建的调控网络显示顺式-二氢槲皮素、异黄杞苷、4,7-二羟基-5-甲氧基-6-甲基-8-甲酰基黄烷等为关键成分，PPI网络分析确定过氧化物酶体增殖物激活受体γ（PPARG）、白细胞介素（IL）-6、IL-1b、肿瘤坏死因子（TNF）、前列腺素内过氧化物合酶2（PTGS2）为核心靶点。GO富集关键生物过程包括对脂多糖的细胞反应、白细胞趋化等，细胞组分为膜筏、膜微区等，分子功能为细胞因子活性、趋化因子活性等；KEGG富集核心通路含IL-17信号通路、TNF信号通路、核因子κB（NF-κB）信号通路等。分子对接显示顺式-二氢槲皮素与PTGS2结合能最低，核心成分与靶点结合良好。结论 土茯苓可能通过异黄杞苷、顺式-二氢槲皮素等活性成分作用于IL-6、IL-1b、PTGS2等核心靶点，调控IL-17、TNF、NF-κB等通路协同发挥抗痛风性关节炎作用。

Objective To explore the mechanism of Smilacis Glabrae Rhizoma in the treatment of gouty arthritis based on network pharmacology and molecular docking technology. Methods The active components and their potential targets of Smilacis Glabrae Rhizoma were screened by searching databases such as TCMIP, TCMSP, HIT, and NPACT. These targets were intersected with gouty arthritis related disease targets to construct a “drug-active component-target-disease” regulatory network and a PPI network. GO functional enrichment analysis and KEGG pathway enrichment analysis were performed. Key active components and core target proteins were selected for molecular docking verification to calculate binding energy and visualize docking conformations. Results A total of 15 active components and 206 potential targets of Smilacis Glabrae Rhizoma were identified. After intersecting with 277 gouty arthritis related targets, 28 common targets were obtained. Regulatory network analysis showed that cis-dihydroquercetin, isorhamnetin-3-O-neohesperidoside, and 4,7-dihydroxy-5-methoxy-6-methyl-8-formylflavan were the key components. PPI network analysis identified PPARG, IL-6, IL-1β, TNF, and PTGS2 as the core targets. GO enrichment analysis revealed that the key biological processes included cellular response to lipopolysaccharide and leukocyte chemotaxis, cellular components included membrane raft and membrane microdomain, molecular functions included cytokine activity and chemokine activity. KEGG enrichment analysis indicated that the core pathways included IL-17 signaling pathway, TNF signaling pathway, and NF-κB signaling pathway. Molecular docking results showed that cis-dihydroquercetin had the lowest binding energy with PTGS2, and the core components bound well to the targets. Conclusion Smilacis Glabrae Rhizoma may exert anti- gouty arthritis effects through the synergistic regulation of multiple pathways including IL-17, TNF, and NF-κB via its active components such as isorhamnetin-3-O-neohesperidoside and cis-dihydroquercetin, which act on core targets including IL-6, IL-1β, and PTGS2.
