目的 基于网络药理学、蛋白质机理和实验验证探讨甘麦大枣汤在治疗儿童注意缺陷多动障碍(Attention deficit and hyperactive disorder，ADHD)模型大鼠肠道炎症中的作用。方法 从网络药理学方法筛选甘麦大枣汤对ADHD模型大鼠肠道炎症的影响作用的相关靶点和相关通路，并通过分子对接验证主要成分和靶点的亲和力。将40只自发性高血压大鼠(SHR)随机分为模型组、哌甲酯组和甘麦大枣汤低、中、高剂量组，每组8只，另设Wistar京都大鼠(WKY)8只为正常组。各组大鼠均每日灌胃治疗，持续3周。通过HE染色技术观察小肠病理情况，酶联免疫吸附测定法(ELISA)和蛋白质印迹法(Western blot)检测白细胞介素1β(IL-1β)、肿瘤坏死因子α(TNF-α)、原癌基因Fos(FOS)表达。结果 网络药理学筛选化学成分117个，预测248个有效靶点。分子对接结果显示，异牡荆素(Isovitexin)、β-胡萝卜素(Beta-carotene)、山奈酚(Kaempferol)、木犀草素(Luteolin)、柚皮素(Naringenin)等成分与AKT1、FOS、VEGFA、TNF等靶点有较强亲和能力。动物实验结果显示甘麦大枣汤可以改善ADHD的核心症状，保护肠道正常功能和状态，下调相关IL-1β、TNF-α、FOS因子含量。结论 甘麦大枣汤可以通过保护SHR大鼠肠道正常功能，下调炎症因子减轻关于其ADHD的核心症状。
Exploring the Effect of Ganmai Dazhao Tang on Intestinal Inflammation in ADHD Model Rats Based on Network Pharmacology
Objective Based on network pharmacology,protein mechanism,and experimental validation,this study aims to explore the role of Ganmai Dazao Tang in treating intestinal inflammation in children with attention deficit hyperactivity disorder(ADHD)model rats.Methods Screening the relevant targets and pathways for the effect of Ganmai Dazhao Tang on intestinal inflammation in ADHD model rats using network pharmacology methods,and verifying the affinity of the main components and targets through molecular docking.Forty spontaneously hypertensive rats(SHR)were randomly divided into model group,methylphenidate group,and low,medium,and high dose groups of Ganmai Dazao Tang,with 8 rats in each group.Additionally,8 Wistar Kyoto rats(WKY)were set as the normal group.Rats in each group were treated daily by gavage for 3 weeks.Observing the pathological condition of the small intestine using HE staining technology,and detecting interleukin-1 using enzyme-linked immunosorbent assay(ELISA)and Western blot methods β(IL-1β),tumor necrosis factor α(TNF-α),Expression of the oncogene Fos(FOS).Results Network pharmacology screened 117 chemical components and predicted 248 effective targets.Molecular docking results showed that Isovitexin β-Ingredients such as beta carotene,kaempferol,luteolin,and naringenin have strong affinity with targets such as AKT1,FOS,VEGFA,and TNF.Animal test results show that Ganmai Dazhao Tang can improve the core symptoms of ADHD,protect normal intestinal function and status,and downregulate related IL-1 β,TNF-α,FOS factor content.Conclusion Ganmai Dazao Tang can alleviate the core symptoms of ADHD in SHR rats by protecting normal intestinal function and downregulating inflammatory factors.
