基于肠道菌群调控FXR-FGF15-FGFR4通路探讨胆囊胆固醇结石湿热证的分子生物学机制

基于肠道菌群调控FXR-FGF15-FGFR4通路探讨胆囊胆固醇结石湿热证的分子生物学机制摘要：

胆囊胆固醇结石是一种常见的消化系统疾病，与肥胖、代谢综合征等多种疾病密切相关。湿热证是中医传统理论中对胆囊胆固醇结石的一种辨证诊断。本研究旨在探讨肠道菌群调控FXR/FGF15/FGFR4通路在胆囊胆固醇结石湿热证形成中的分子生物学机制。通过对肠道菌群、FXR/FGF15/FGFR4通路和湿热证的相关文献进行分析，发现肠道菌群调控FXR/FGF15/FGFR4通路对湿热证和胆囊胆固醇结石的形成具有重要作用。菌群失衡可导致FXR/FGF15/FGFR4通路受损，从而导致胆囊胆固醇结石的形成。此外，本研究框架还对胆囊胆固醇结石的预防和治疗提出一些具有创新性的思路。
