Network pharmacology analysis of Yi-Shen-Gu-Ta i-Ke-Li for recurrent spontaneous abortion in female fitness and athletic populations

Background: Yi-Shen-Gu-Tai-Ke-Li (YSGTKL), a renowned traditional herbal formula, has demonstrated clinical efficacy in addressing recurrent spontaneous abortion (RSA). Despite its widespread utilization in China, the current body of evidence regarding the effectiveness of its herbal components remains insufficient, and the underlying mechanisms of action remain enigmatic. This study endeavors to unravel the mechanisms responsible for the therapeutic effectiveness of YSGTKL in treating RSA, particularly within the context of female fitness and athletic populations. Methods: YSGTKL comprises various herbal plants, selected based on the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Specific drug targets associated with RSA were meticulously identified and corroborated using multiple reputable sources, including DrugBank, GeneCards, and Online Mendelian Inheritance in Man. The GEO database was leveraged to pinpoint differentially expressed genes (DEGs) relevant to RSA within female fitness and athletic populations. Subsequently, a comprehensive drug-compound-gene-disease network was meticulously constructed and visualized using Cytoscape software. Functional insights were gleaned through Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Within this network, a subset of hub genes was discerned through a protein-protein interaction (PPI) network analysis, specifically tailored to female fitness and athletic populations. To validate key active ingredients and core targets, molecular docking analyses were meticulously performed, taking into account the unique physiological aspects of female athletes and fitness enthusiasts.

Effect of baotaiyin on IL-23 /Th17 immune inflammatory axis in mouse model of spontaneous abortion. / ä¸­è¯ä¿èƒŽé¥®å¯¹è‡ªç„¶æµäº§å°é¼ æ¨¡åž‹IL-23/Th17å ç–«ç‚Žç—‡è½´çš„å½±å“.

OBJECTIVES: The mechanism for traditional Chinese medicine in treating of recurrent spontaneous abortion is not clear. This study aims to explore the mechanism of baotaiyin in the treatment of recurrent abortion by regulating the immune inflammatory axis of interleukin (IL)-23/helper T cell (Th)17. METHODS: Spontaneous abortion model mice were randomly divided into a model group, 3 dose (low, medium, and high) groups of baotaiyin, with 10 mice in each group. After 14 days of medication, the levels of IL-17, IL-23, IL-10, and TGF-ß in serum were detected with enzyme-linked immunosorbent assay. The proportion of Th17 and regulatory T cells (Treg) cells in spleen lymphocytes was tested with flow cytometry. The expressions of (retinoid-related orphan receptor γt, ROR-γt) and forkhead box P3 (FOXP3) mRNA in decidua tissues was detected with RT-PCR. Embryo absorption rate was counted. RESULTS: Compared with the model group, the absorption rate of embryo and Th17/Treg cell ratio in baotaiyin medium- and high-dose groups were decreased significantly (all P<0.05); the levels of IL-17 and IL-23 in serum were decreased (both P<0.05), while the levels of TGF-ß and IL-10 in baotaiyin medium- and high-dose groups were increased (P<0.05, P<0.01, respectively); the expression of ROR-γt mRNA was decreased and the expression of FOXP3 mRNA was increased (all P<0.01) in decidua tissues of baotaiyin medium- and high-dose groups. CONCLUSIONS: Baotaiyin inhibits the positive feedback cycle of IL-23/Th17 immune inflammatory axis, which regulates Th17/Treg cell balance, mediates the maternal and fetal immune tolerance, and prevents the recurrent abortion.

Tiaoshen Tongluo Attenuates Fibrosis by Modulating the TGF-ß1/Smad Pathway in Endometrial Stromal Cells and a Rat Model of Intrauterine Adhesion.

Intrauterine adhesion (IUA) is a serious complication caused by excessive fibrosis resulting from endometrial repair after trauma. The traditional Chinese medicine Tiaoshen Tongluo recipe (TTR) contains ingredients associated with the alleviation of fibrosis. The transforming growth factor-ß1 (TGF-ß1)/Smad pathway is thought to mediate fibrosis in IUA. In this study, we evaluated the influence of TTR on endometrial fibrosis in a rat model of IUA and in TGF-ß1-stimulated endometrial stromal cells (ESCs). TTR was found to alleviate the level of endometrial fibrosis in a rat model of IUA. A higher number of collagen fibers and greater damage were observed in the endometrial tissue of untreated rats compared to those treated with TTR. The expression of TGF-ß1, Smad2, Smad3, and Smad4 was upregulated following IUA, whereas Smad7 expression was downregulated. TTR lowers the expression of TGF-ß1, Smad2, Smad3, and Smad4 but increases the expression of Smad7 in vivo, indicating that TTR can modulate the expression of the TGF-ß1/Smad pathway to mediate fibrosis. In ESCs, the phosphorylation of Smad2 and Smad3 and upregulation of Smad4 were induced by TGF-ß1 whereas the expression of Smad7 was inhibited. Administration of TTR reduces the phosphorylation of Smad2 and Smad3, increases Smad4 expression induced by TGF-ß1, and promotes the expression of Smad7. TTR modulates the TGF-ß1/Smad pathway to alleviate the generation of fibrotic tissue in response to IUA.
