摘要：目的:基于网络药理学和实验验证探究敦煌芮草膏治疗冻伤的作用机制。方法:通过网络药理学筛选敦煌芮草膏干预冻伤的作用靶点。运用敦煌芮草膏治疗冻伤模型大鼠,观察药物作用效果、验证网络药理学富集分析结果。结果:共选出239个药物活性成分、186个疾病靶点、36个药物疾病共同靶点;KEGG通路富集分析得到96条通路,主要富集于Toll样受体信号通路、IL-17信号通路、肿瘤坏死因子信号通路、AGE-RAGE信号通路、Th17细胞分化等通路,Toll样受体信号通路可能在敦煌芮草膏治疗冻伤过程中起重要作用。动物实验表明,与模型组相比,敦煌芮草膏各剂量组大鼠皮肤冻伤明显改善,创口愈合率升高,肿胀率下降,创面组织上皮化明显,炎症浸润减少,血管新生增加,胶原纤维含量增多。局部皮损组织TLR4、MyD88、NF-κB p65 mRNA及蛋白表达不同程度降低,中剂量组效果最好。结论:敦煌芮草膏治疗冻伤具有多成分、多靶点、多通路协同作用的特点,可能通过抑制TLR4/MyD88/NF-κB信号通路激活减少冻伤大鼠血清促炎介质释放,减轻炎症反应,提高组织重塑速率,促进冻伤愈合,发挥冻伤治疗作用,为后续深入研究敦煌芮草膏治疗冻伤的机制提供了依据。
Objective:To verify mechanism of Dunhuang Ruicao ointment in frostbite treatment through network pharmacology and experiment.Methods:Targets of Dunhuang Ruicao ointment in intervention of frostbite was screened through network pharmacology.Dunhuang Ruicao ointment was used to treat rat model of frostbite.Effect of drug was observed and results of network pharmacological enrichment analysis were verified.Results:A total of 239 active drug components,186 disease targets and 36 common targets were screened.KEGG pathway enrichment screened out 96 pathways,mainly enriched in Toll-like receptor signaling pathway,IL-17 signaling pathway,tumor necrosis factor signaling pathway,AGE-RAGE signaling pathway,Th17 cell differentiation pathway,suggesting Tolllike receptor signaling pathway may play an important role in treatment of frostbite by Dunhuang Ruicao ointment.Animal experiments showed that compared with model group,skin frostbite of rats treated with different doses of Dunhuang Ruicao ointment group was significantly improved,wound healing rate was increased,swelling rate was decreased,wound tissue epithelialization was obvious,inflammatory infiltration was reduced,angiogenesis was increased,and collagen fiber content was increased.mRNA and protein expressions of TLR4,MyD88 and NF-κB p65 in local skin lesions were decreased to different degrees,and middle-dose group had the best effect.Conclusion:Dunhuang Ruicao ointment in treatment of frostbite has characteristics of multiple components,multiple targets,multiple pathways synergy,probably playing a role in treatment of frostbite by inhibiting TLR4/MyD88/NF-κB signaling pathway activated to reduce frostbite rats serum proinflammatory media release,reduce inflammation,improve rate of tissue remodeling,promote healing of frostbite,providing a theoretical basis for further study of complex mechanism of Dunhuang Ruicao ointment in treatment of frostbite.
