    Abstract:
    ETHNOPHARMACOLOGICAL RELEVANCE: Baiheqingjin Decoction (BHQJ), which consists of 7 traditional Chinese herbs including Baibu (Stemona tuberosa Lour.), Hezi (Terminalia chebula Retz.), Mahuang (Ephedra sinica Stapf.), Ziwan (Aster tataricus L. f.), Dilong (Pheretima), Sangbaipi (Morus alba L.), and Xianhecao (Agrimonia pilosa Ledeb.). BHQJ is commonly used for treating cough asthma, and variant cough-variant asthma as it, is effective in improving asthma symptoms and reducing airway inflammation. AIM OF THE STUDY: To investigate the mechanisms of BHQJ in treating allergic asthma. MATERIALS AND METHODS: We collected information about the components and targets of 6 Chinese medicines (excluding Pheretima) from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Additionally, we obtained genes associated with asthma from six disease databases. To create a protein-protein interaction network, we conducted an intersection analysis using differentially expressed genes derived from RNA transcriptome data. Subsequently, we carried out Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. To validate the findings from network pharmacology and transcriptomics, we established an allergic asthma mouse model induced by ovalbumin and conducted in vivo experiments. RESULTS: Using network pharmacology and transcriptomics analyses, we identified the pathways including the PI3K/AKT signaling pathway, and NF-κB signaling pathway. Among these, the involvement of the PI3K/AKT/NF-κB signaling pathway in various pathological processes of asthma, such as airway inflammation, smooth muscle contraction, and excessive mucus production, are well-documented. Histopathological examinations indicated that BHQJ had the potential to mitigate inflammatory cell infiltration and the excessive growth of goblet cells in the airways of asthmatic mice, consequently reducing mucus secretion. Results from Western blot demonstrated that BHQJ could inhibit the activation of the PI3K/AKT/NF-κB pathway at the protein levels. Enzyme-linked immunosorbent assay findings revealed that BHQJ could reduce the production of typical "type 2 asthma" cytokines and immunoglobulin (Ig) E in the blood. These discoveries imply that BHQJ has the potential to reduce the release of inflammatory cytokines and suppress the overactivation of the PI3K/AKT/NF-κB signaling pathway, thus offering a therapeutic approach for asthma. CONCLUSION: Our research offers initial insights into the fundamental mechanisms through which BHQJ treats asthma. This study reveals the potential mechanism of BHQJ in treating asthma, particularly its role in reducing inflammatory cytokines, mucus production, and cell infiltration, as well as inhibiting the expression of PI3K/AKT/P65 phosphorylated protein. These findings indicate the potential of BHQJ in treating asthma. In summary, our study provides preliminary insights into the asthma treatment mechanism of BHQJ and provides guidance for future research.
