Network pharmacology analysis and clinical verification of Jishe Qushi capsules in rheumatoid arthritis treatment

Abstract

The study aimed to elucidate the effective chemical composition and molecular mechanism of rheumatoid arthritis (RA) treatment with Jishe Qushi capsules (JSQS) and perform clinical validation. The effective chemical components were screened by a database. We used Cytoscape software to construct the key target-RA composite target network of JSQS. Gene Ontology biofunctional analysis and Kyoto encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed for the key targets, followed by molecular docking validation of core key targets. Ninety-nine patients chosen were divided into 49 cases in the treatment group and 50 cases in the control group according to the random number table method. The control group was treated with the combination of methotrexate (MTX) plus Glucosidorum Tripterygll Totorum. The treatment group was treated with MTX plus JSQS. The treatment effects of the 2 groups were evaluated. A total of 118 key anti-RA targets were obtained for JSQS. Quercetin in Panax notoginseng, vanillic acid, scopoletin, physcion in Gardneria angustifolia, 3,5-dimethyl-4-hydroxybenzaldehyde in Zaocys dhumnades, kaempferol in Radix Paeoniae Alba, and protocatechuic aldehyde in Cibotium barometz were the main active chemical components in the composite target network. Topology analysis yields core key targets, such as TP53, INS, IL6, VEGFA, MYC, CASP3, ESR1, EGF, CCND1, PPARG, ERBB2, NFKBIA, TLR4, RELA, and CASP8, and the results of KEGG enrichment analysis showed that JSQS mainly works through pathways in cancer, phosphatidylinositol-3-kinaseRAC–serine/threonine-protein kinase signaling, and mitogen-activated protein kinase (MAPK) signaling pathway, and aryl hydrocarbon receptor nuclear translocator signaling pathway. Molecular docking results showed that the binding fraction of PPARG, VEGFA and the effective active ingredients of ridged snake dispelling capsule was >70. In the clinical trial, morning stiffness, joint pain, and VAS scores of post-treatment in the treatment group were lower than those in the control group (P < .05). Additionally, ESR, CRP, RF, anti-CCP, TNF-α, IL-6, IL-17, and Th17/Treg were lower in the treatment group than in the control group (P < .05). JSQS exert multicomponent, multipathway, and multitarget synergistic actions in RA treatment. It can significantly improve the clinical symptoms and quality of life and delay the progression of RA disease.
