Abstract:
Objective To analyze the mechanism of Huangwu Ganfu Ointment in relieving pain of knee osteoarthritis(KOA)based on network pharmacology;To verify it in animal experiments.Methods The active components of Huangwu Ganfu Ointment were obtained by TCMSP database,PubChem database and SwissADME platform,the effective components were screened,and the targets were obtained from SEA database.KOA disease-related targets were obtained from GeneCards,OMIM and other databases,and the intersection targets were obtained.A effective component-target-disease network was constructed using Cytoscape 3.9.0 Software.Protein-protein interaction(PPI)network was constructed by STRING database and core targets were screened.GO and KEGG enrichment analysis of intersection targets were analyzed using DAVID platform.The KOA rat model with cold and damp syndrome was established,and the intervention of Huangwu Ganfu Ointment was carried out.The efficacy was observed and the core target expressions were detected.Results Totally 104 effective components were screened from Huangwu Ganfu Ointment,and 59 potential targets were obtained for treating KOA.PPI network interaction analysis obtained the important targets of IL6,IL1B and PTGS2.KEGG enrichment results showed that Huangwu Ganfu Ointment may involve 84 signaling pathways such as IL-17,TNF,TRP and NF-κB in the treatment of KOA,most of which were related to inflammation.The results of animal experiments showed that Lecuesne MG scores increased in the model rats(P<0.05),and paw withdrawal threshold(PWT)significantly decreased(P<0.05).Compared with model group,PWT in Huangwu Ganfu Ointment medium-and high-dosage groups were significantly recovered,and synovitis Krenn score decreased(P<0.05).The Mankin score of cartilage tissue of Huangwu Ganfu Ointment high-dosage group decreased(P<0.05).The contents of IL-6 and IL-1β in all Huangwu Ganfu Ointment groups decreased(P<0.01).Huangwu Ganfu Ointment medium-and high-dosage groups could down-regulate the expression of TRPV1 protein(P<0.05,P<0.01).Conclusion The mechanism of Huangwu Ganfu Ointment in alleviating the pain of KOA may be related to reducing inflammatory response,reducing the release of inflammatory factors of IL-1β and IL-6,alleviating inflammatory pain sensitivity of KOA,and down-regulating the expression level of TRPV1.
