摘要: 目的 基于网络药理学探索六味酸枣汤治疗围绝经期失眠的作用机制,并运用分子对接和动物实验进行验证。方法 借助TCMSP 和 Batman-TCM 数据库检索六味酸枣汤的活性成分和作用靶点,并构建“中药-活性成分-靶点”网络。以“Perimenopausal Insomnia”为关键词在OMIM、Genecards和Gene数据库获取疾病靶点。将共同靶点导入STRING 数据库和Cytoscape软件筛选核心治疗靶点,借助DAVID数据库进行GO富集分析和KEGG通路分析。利用AutoDock对六味酸枣汤主要活性成分与核心靶点进行分子对接实验,同时以动物实验验证结果。取48只大鼠随机分为假手术组(8只)和造模组(40只),采用双侧卵巢切除术和对氯苯丙氨酸腹腔注射建立PI模型。将造模组大鼠随机分为模型组、阳性对照组和中药低、中、高剂量组,分别予以生理盐水10 mL/kg、唑吡坦10 mg/kg以及六味酸枣汤9.0、18.0、36.0 g/kg灌胃,连续8 d。末次给药后进行戊巴比妥钠协同的翻正反射实验,记录各组睡眠潜伏期和睡眠时长,ELISA法测定血清雌激素、卵泡刺激素、黄体生成素等激素水平,WB和PCR法分别检测下丘脑组织中ESR1与SIRT1的蛋白及mRNA水平。结果 共筛选出六味酸枣汤活性成分99个,药物靶点389个,PI相关靶点187个,药物与PI共同靶点15个;核心活性成分主要为亚美异粟碱、酸枣仁环肽、白桦脂酸等,核心靶点包括ESR1、SIRT1、SERPINE1、COMT和CCL2等。GO分析结果主要包括RNA聚合酶II启动子对转录的正向调节、对药物的反应和转录的正向调节等生物学过程;KEGG富集通路包括多巴胺能突触途径和酪氨酸、色氨酸代谢等。分子对接结果显示六味酸枣汤主要活性成分与ESR1、SIRT1和SERPINE1有较好的结合能,与酒石酸唑吡坦相当。动物实验表明,六味酸枣汤可有效改善大鼠失眠症状(P<0.01),调节雌激素等HPO轴相关激素水平(P<0.05),促进ESR1和SIRT1的蛋白与mRNA表达(P<0.01)。结论 六味酸枣汤可能通过亚美异粟碱、酸枣仁环肽、白桦脂酸等多种活性成分协同调控ESR1、SIRT1和SERPINE1等基因表达,进而达到治疗围绝经期失眠的效果。

Abstract: Objective To explore the therapeutic mechanism of Liuwei Suanzao decoction (LWSZD) for perimenopausal insomnia (PI) based on network pharmacology. Methods TCMSP and Batman-TCM databases were searched for the active ingredients and targets of LWSZD and a herb- active ingredient-target network was constructed, and the disease targets were obtained from the OMIM, Genecards and Gene databases. The common targets were imported into STRING database and Cytoscape software to screen the core therapeutic targets, and GO enrichment and KEGG pathway analyses were performed using DAVID database. Molecular docking of the main active ingredients of LWSZD and the core targets was conducted using AutoDock, and the results were verified by observing the therapeutic effects of LWSZD and zolpidem in a rat model of PI induced by bilateral ovariectomy and intraperitoneal p-chlorophenylalanine injection. Results A total of 99 active ingredients, 389 drug targets, 187 PI-related targets, and 15 drug-PI common targets were screened. The core active ingredients were armepavine, sanjoinenine and mairin, and the core targets included ESR1, SIRT1, SERPINE1, COMT and CCL2, which were involved in the positive regulation of transcription from RNA polymerase II promoter, signal transduction, response to drug and positive regulation of transcription and in the pathways of dopaminergic synapses, tyrosine metabolism and tryptophan metabolism. Molecular docking results showed that LWSZD had a strong binding with ESR1, SIRT1 and SERPINE1 and was comparable to zolpidem. In the rat models of PI, treatment with LWSZD effectively alleviated the symptoms of insomnia (P<0.01), improved the levels of estrogen and other HPO axis-related hormones (P<0.05), and promoted the mRNA and protein expressions of ESR1 and SIRT1 in the hypothalamus tissues (P<0.01). Conclusion The active ingredients armepavine, sanjoinenine and mairin in LWSZD may synergistically regulate the expressions of ESR1, SIRT1 and SERPINE1 to improve PI in rats.
