目的 基于数据挖掘、网络药理学和分子对接分析海派名医顾乃芳治疗特应性皮炎的用药规律及作用机 制。方法 收集上海市中医医院门诊病历系统中顾乃芳 2021 年 1 月至 2024 年 1 月治疗特应性皮炎的中药处 方,建立中药治疗特应性皮炎数据库。通过关联规则和系统聚类挖掘核心组方药物;借助网络药理学预测核心 组方药物治疗特应性皮炎的作用机制,通过分子对接进一步验证。结果 共纳入患者 350 例,1 020 首处方, 233 味中药。关联规则和系统聚类分析获得核心组方药物:金银花、蝉蜕、五味子、乌梅、赤芍、牡丹皮、地 黄、黄芩、土茯苓、徐长卿、僵蚕。网络药理学预测核心中药活性成分 59 个,潜在靶点 77 个。通过蛋白质- 蛋白质相互作用网络(PPI)分析确定 5 个核心靶点,包括白细胞介素 6(IL6)、肿瘤坏死因子(TNF)、信号转导 及转录激活因子 3(STAT3)、干扰素 γ(IFNG)、白细胞介素 1β(IL1B)。京都基因与基因组百科全书(KEGG)通 路分析发现,核心中药的活性成分主要通过白细胞介素 17(IL17)、TNF、Janus 激酶信号转导和转录激活因子 (JAK-STAT)等信号通路作用于特应性皮炎。分子对接结果显示,槲皮素与 IL6、黄芩素与 STAT3,β-谷甾醇 与 TNF 等都具有良好的结合能力及稳定性。结论 顾乃芳治疗特应性皮炎基本思路为清热凉血,利湿祛风, 核心药物主要成分以槲皮素、山柰酚、β-谷甾醇为代表,这些成分通过 IL17、TNF、JAK-STAT 等信号通路作 用于 IL6、TNF、STAT3 等靶点,可为中医治疗特应性皮炎药物的筛选提供参考。

Objective To analyze the medication rules and therapeutic mechanisms of Shanghai-style famous physician Gu Naifang in treating atopic dermatitis (AD) through data mining,network pharmacology,and molecular docking. Methods Chinese herbal prescriptions for AD treated by Gu Naifang from January 2021 to January 2024 were collected from the outpatient medical record system of Shanghai Traditional Chinese Medicine Hospital to establish a database.Core herbal combinations were identified using association rule mining and hierarchical clustering. Network pharmacology was employed to predict the mechanisms of these core herbs against AD,followed by molecular docking validation. Results A total of 350 patients, 1 020 prescriptions, and 233 herbs were included. Core herbal combinations identified were: Lonicerae Japonicae Flos, Cicadae Periostracum, Schisandrae Chinensis Fructus, Mume Fructus,Paeoniae Radix Rubra,Moutan Cortex,Rehmanniae Radix,Scutellariae Radix,Smilacis Glabrae Rhizoma, Cynanchi Paniculati Radix et Rhizoma, Bombyx Batryticatus. Network pharmacology predicted 59 active components and 77 potential targets. Protein-protein interaction (PPI) network analysis revealed five core targets: interleukin-6(IL6), tumor necrosis factor (TNF), signal transducer and activator of transcription 3(STAT3), interferon gamma (IFNG),and interleukin-1β(IL1B). KEGG pathway analysis indicated that the active components primarily acted on AD via IL17, TNF, and JAK-STAT signaling pathways. Molecular docking demonstrated strong binding affinity and stability between quercetin-IL6, baicalein-STAT3, and β -sitosterol-TNF. Conclusion Gu Naifang’s treatment strategy for AD emphasizes heat-clearing, blood-cooling, dampness-resolving, and winddispelling. Core components (e.g.,quercetin,kaempferol,β-sitosterol) exert therapeutic effects by modulating IL6, TNF,and STAT3 through IL17/TNF/JAK-STAT pathways,providing a reference for TCM-based AD drug screening.
