Efficacy of Duhuo Jisheng Decoction in Treating Ankylosing Spondylitis: Clinical Evidence and Potential Mechanisms

Duhuo jisheng decoction (dhjsd) is an ancient compound widely used in the treatment of ankylosing spondylitis (as).However, its efficacy is controversial, and its mechanism of action is not clear enough.Using meta-analysis and network pharmacology, our study evaluated the clinical efficacy of dhjsd in the treatment of as and explored its mechanisms of action.Methods.We searched medical databases, including embase, pub med, the china national knowledge infrastructure databases, wanfang, and the chinese scientific journal database, to identify studies that met the inclusion criteria.Rev man 5.3 software was used for the meta-analysis.The compounds and the potential protein targets of dhjsd were obtained from the traditional chinese medicine systems pharmacology (tcmsp) database and analysis platform.As was treated as a search query in the ncbi, pharm gkb, ttd, drug bank, and omim databases to obtain disease-related genes.The overlapping targets of dhjsd and as were identified, and then gene ontology functional enrichment and kyoto encyclopedia of genes and genomes enrichment analyses were performed.Cytoscape was employed to construct a drug-compound-target network and a protein-protein interaction (ppi) network.Cyto hubba was utilized to select the hub genes.Results.A total of 10 studies involving 860 participants were included in the meta-analysis.Compared with the control, dhjsd treatment significantly improved clinical symptoms; reduced the erythrocyte sedimentation rate (esr), the c-reactive protein (cpr), and interleukin 6 (il-6) levels; increased the degree of motion of the chest; reduced the visual analog scale (vas) pain score; reduced schober’s test values; reduced the finger-to-floor distance; reduced the duration of morning stiffness.However, the differences were not statistically significant in the bath ankylosing spondylitis functional index scores, the bath ankylosing spondylitis disease activity index scores, the bone gla-containing protein (bgp) levels, or the bone alkaline phosphatase (balp) levels.In terms of adverse events, dhjsd treatment of as reduced the incidence of gastrointestinal events, the incidence of skin events, and the incidence of abnormal liver function; however, there was no statistically significant reduction in the incidence of adverse renal function events.Subgroup analysis showed that in the treatment of as, the clinical effect of dhjsd for as was better than that of the controls for both treatment durations, ≤2 months and &gt;2 months.A total of 178 active compounds and 47 related potential targets were identified for dhjsd in the treatment of as, including four hub genes (cxcl8, ptgs2, vegfa, and stat3).The core active ingredients of dhjsd in the treatment of as were mainly quercetin, kaempferol, licochalcone a, and isorhamnetin.Dhjsd treatment of as-related pathways mainly involved the il-17 signaling pathway, the tnf signaling pathway, and the rheumatoid arthritis signaling pathway.Conclusion.The above results suggest that dhjsd acts on as through multiple targets, components, and pathways with significant clinical efficacy.Future studies may further explore the active components of dhjsd.
