Abstract
BACKGROUND: Asthma seriously affects people's survival and quality of life, causing a huge economic burden on society. Modern clinical use of Qianjinweijing Decoction (QJWJ) for the treatment of asthma has achieved good results. However, there is still a lack of research on its efficacy and mechanism of action. Therefore, the purpose of this study is to evaluate the efficacy of QJWJ in the treatment of asthma by systematic review and meta-analysis, and to explore its potential mechanism by network pharmacology. METHODS: The meta-analysis was performed to search for studies published before May 2023 in 7 databases, and Revman 5.4 and R language softwares were used for analysis. Network pharmacology was based on open databases and softwares such as Cytoscape, Perl, Autoduck Vina, and R language. RESULTS: A total of 14 studies were included, involving 1200 patients. The results of the meta-analysis showed that QJWJ could significantly improve the clinical efficacy of asthma patients compared with routine pharmacotherapy (risk ratio = 1.22, 95% CI [1.16, 1.28], P < .00001), enhance lung function, such as FEV1/FVC (mean difference [MD] = 5.63, 95% CI [1.45, 9.81], P = .008), FEV1% (MD = 5.03, 95% CI [4.32, 5.74], P < .00001), PEF (standardized mean difference = 1.37, 95% CI [1.03, 1.71], P < .00001), and increase traditional Chinese medicine syndrome score (MD = -2.50, 95% CI [-4.81, -0.19], P = .03). The results of network pharmacology suggested that the 4 traditional Chinese medicines in QJWJ included 35 active ingredients and 34 potential targets for the treatment of asthma. The core ingredients involved were stigmasterol, β-sitosterol, hederagenin, and gibberellin 7. The core targets were PTGS2, BCL2, and CASP3. The interaction pathway between QJWJ and asthma was mainly enriched in p53, cyclic guanosine monophosphate-protein kinase G, IL-17, and advanced glycation end products-receptor for advanced glycation end products signaling pathways. Molecular docking showed that the core ingredients had good binding activity with the core targets. CONCLUSION: QJWJ is effective in the treatment of asthma, and the therapeutic mechanism may be related to its regulation of inflammation, immunity, and apoptosis.
