Background: Meniere’s disease (MD) is a rare inner ear disorder characterized by endolymphatic hydrops and symptoms such as vertigo and hearing loss, with no curative treatment currently available. XuanYunNing tablets (XYN) have been clinically used to treat MD, but their molecular mechanisms remain unclear. Objective: This study aimed to systematically evaluate the pharmacological effects of XYN in a guinea pig model of MD and to elucidate the underlying molecular mechanisms of both MD pathogenesis and XYN intervention through integrated multi-omics analyses, including transcriptomics, proteomics, and bioinformatics. Methods: A guinea pig model of endolymphatic hydrops was induced by intraperitoneal injection of desmopressin acetate (dDAVP). Pharmacodynamic efficacy was evaluated via behavioral scoring and histopathological analysis. The differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) modulated by XYN treatment were identified using high-throughput transcriptomic and proteomic sequencing. These data were integrated through multi-omics bioinformatic analysis. Key molecular targets and signaling pathways were further validated using RT-qPCR and Western blotting. Results: Pharmacological evaluations showed that guinea pigs in the model group exhibited a 26% increase in endolymphatic hydrops area, while high-dose XYN treatment reduced this area by 19% and significantly improved functional parameters, including overall physiological condition (e.g., weight and general appearance), auricular reflexes to low-, medium-, and high-frequency sound stimuli, nystagmus, and the righting reflex. High-throughput sequencing combined with integrative omics analysis identified 513 potential molecular targets of XYN. Subsequent network and module analyses pinpointed the JAK-STAT signaling pathway as the central axis. Mendelian randomization (MR) analysis further supported a causal relationship between MD and metabolic, immune, and inflammatory traits, reinforcing the central role of JAK-STAT signaling in both MD progression and XYN-mediated intervention. Mechanistic studies confirmed that XYN downregulated IFNG, IFNGR1, JAK1, p-STAT3/STAT3, and AOX at both mRNA and protein levels, thereby inhibiting aberrant JAK-STAT pathway activation in MD model animals. In addition, a total of 125 chemical constituents were identified in XYN by UHPLC-MS analysis. ZBTB20 and other molecules were identified as potential blood-based biomarkers for MD. Conclusions: This study reveals that XYN alleviates MD symptoms by disrupting a pathological cycle driven by JAK-STAT signaling, inflammation, and metabolic dysfunction. These findings support the clinical potential of XYN in the treatment of Meniere’s disease and may inform the development of novel therapeutic strategies.

Background: Respiratory tract infections (RTIs) are characterized by a high mortality rate and clinical incidence. Bairui granules (BG), which employ a method of heat elimination and detoxification, have demonstrated benefits in the treatment of infectious respiratory diseases. Methods: A computerized search of 6 databases was conducted to identify randomized controlled trials (RCTs) relevant to the treatment of RTIs with BG up to November 30, 2023. Two researchers independently conducted data extraction, risk of bias assessment, and grading analysis. To evaluate the stability of the results, trial sequential analysis was employed. Results: This meta-analysis included 31 RCTs with a total of 4073 patients and demonstrated that the use of BG in the treatment of RTIs was associated with enhanced treatment efficacy (relative risk = 1.19, 95% credible interval: 1.16–1.22, P < .001). It also indicated a faster resolution of symptoms including pulmonary rales, cough, and fever, as well as a reduction in serological index factors, compared to the use of Western medicine treatment (WT) alone. Additionally, the duration of hospitalization for patients was significantly reduced (relative risk = −1.36, 95% credible interval: −1.55 to −1.17, P < .001). Trial sequential analysis confirmed the stability and conclusive evidence of the study results. The efficacy of treating RTIs with BG, either alone or in combination with WT, was found to be superior to WT alone. However, further high-quality RCTs are necessary to validate these outcomes. Conclusion: The effectiveness of treating RTIs using BG alone or in combination with WT was determined to be superior to using WT alone, with no serious adverse effects observed. However, additional RCTs are essential to further confirm the findings of this study.

Background: Malignant pleural effusion (MPE) is a frequently observed complication in advanced malignant tumors. Clinical studies have shown that lentinan for injection (LNT) is beneficial for improving patients’ quality of life and prolonging their survival. The purpose of this meta-analysis is to evaluate the efficacy and safety of LNT combining cisplatin in the treatment of MPE. Methods: Randomized controlled trials (RCTs) of LNT combining cisplatin in the treatment of MPE were searched in 6 literature databases from the establishment time of each database by 2 researchers. According to the inclusion criteria, 2 researchers independently screened studies, assessed the risk of bias and conducted subgroup analyses for different outcome indicators according to the specific characteristics of the included literature. Analyzing the data by Revman software, and evaluating the stability of the results by Stata software. Results: A total of 52 RCTs were included. The results showed that combined use of LNT and cisplatin could improve the treatment effect, and the difference between groups was statistically significant (RR = 1.40, 95%CI: 1.33 ~ 1.46, P < .001). And the combined use of LNT could increase the quality of life (RR = 1.45, 95%CI: 1.35 ~ 1.56, P < .001). The using of LNT could significantly decrease the incidence of gastrointestinal reactions (RR = 0.86, 95%CI: 0.78 ~ 0.94, P < .001). Sensitivity analysis results showed that there were no qualitative changes in the indicator, and suggested the possibility of publication bias. Conclusions: Available evidence suggested the combined use of LNT and cisplatin showed better efficacy in treating MPE without increasing ADR incidence than using cisplatin alone. LNT is an ideal treatment for MPE, which has high clinical application value.

Background: Acute pharyngitis (AP) refers to the acute inflammation of the pharynx, characterized by swelling and pain in the throat. Shuangyang houbitong granules (SHG), a traditional Chinese medicine compound, have been found to be effective in providing relief from symptoms associated with AP. Methods: The chemical components of SHG were screened using Traditional Chinese Medicine Systems Pharmacology database, HERB database, and China National Knowledge Infrastructure. The targets of the granules were predicted using SwissTargetPrediction database. A network was constructed based on the targets of AP obtained from Genecards database, and protein–protein interaction analysis was performed on the intersection targets using STRING database. Key targets were screened for Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis, and the binding activity of components and targets was predicted using AutoDockTools-1.5.7. Results: A total of 65 components of SHG that met the screening criteria were retrieved, resulting in 867 corresponding targets. Additionally, 1086 AP target genes were retrieved, and 272 gene targets were obtained from the intersection as potential targets for SHG in the treatment of AP. Molecular docking results showed that the core components genkwanin, acacetin, apigenin, quercetin can stably bind to the core targets glyceraldehyde 3-phosphate dehydrogenase, interleukin 6, tumor necrosis factor, serine/threonine protein kinase, tumor protein 53, and epidermal growth factor receptor. Conclusion: The research results preliminarily predict and verify the mechanism of action of SHG in the treatment of AP, providing insights for further in-depth research.
