Clinical Evaluation and Exploration of Mechanisms for Modified Xiebai Powder or Modified Xiebai Powder Combined with Western Medicine in the Treatment of Pneumonia.

Abstract

Objective To systematically evaluate the clinical efficacy of modified Xiebai Powder or modified Xiebai Powder combined with Western medicine in the treatment of pneumonia and explore its potential mechanism of action. Methods Meta-analysis was used to screen the eligible literature on randomized controlled trials (RCTs) about Xiebai Powder in the treatment of pneumonia, and Review Manager 5.3 software was used for statistical analysis of the data. Based on the results of the meta-analysis, the active ingredients in Xiebai Powder and their therapeutic targets, disease-related targets, and intersection targets were screened using methods of network pharmacology, and their biological processes and key signaling pathways were analyzed using bioinformatics tools. Molecular docking was carried out to verify and predict the mechanisms for Xiebai Powder combined with Western medicine in the treatment of pneumonia. Results A total of 16 papers were screened out, with a total of 1,465 patients. The results of the meta-analysis showed that modified Xiebai Powder or modified Xiebai Powder combined with Western medicine were superior to conventional Western medicine in terms of clinical efficacy, shortening the disappearance time of symptoms (body temperature, cough, and pulmonary rales) and reducing the level of C-reactive protein, and the incidence of adverse reactions was significantly reduced. A total of 40 active ingredients in Xiebai Powder and 285 therapeutic targets of Xiebai Powder combined with azithromycin after deduplication were screened out from the database. KEGG enrichment analysis showed that Xiebai Powder combined with azithromycin might play a role in the treatment of pneumonia through the IL-17 signaling pathway, tumor necrosis factor signaling pathway, C-type lectin receptor signaling pathway, Toll-like receptor signaling pathway, and HIF-1 signaling pathway. Conclusions Modified Xiebai Powder or modified Xiebai Powder combined with azithromycin has better effects in treating pneumonia, and modified Xiebai Powder combined with azithromycin may play a role in treating pneumonia through several pathways such as the IL-17 signaling pathway.
