基于腸道菌群調控FXR-FGF15-FGFR4通路探討膽囊膽固醇結石濕熱證的分子生物學機制

基于腸道菌群調控FXR-FGF15-FGFR4通路探討膽囊膽固醇結石濕熱證的分子生物學機制摘要：

膽囊膽固醇結石是一種常見的消化系統(tǒng)疾病，與肥胖、代謝綜合征等多種疾病密切相關。濕熱證是中醫(yī)傳統(tǒng)理論中對膽囊膽固醇結石的一種辨證診斷。本研究旨在探討腸道菌群調控FXR/FGF15/FGFR4通路在膽囊膽固醇結石濕熱證形成中的分子生物學機制。通過對腸道菌群、FXR/FGF15/FGFR4通路和濕熱證的相關文獻進行分析，發(fā)現(xiàn)腸道菌群調控FXR/FGF15/FGFR4通路對濕熱證和膽囊膽固醇結石的形成具有重要作用。菌群失衡可導致FXR/FGF15/FGFR4通路受損，從而導致膽囊膽固醇結石的形成。此外，本研究框架還對膽囊膽固醇結石的預防和治療提出一些具有創(chuàng)新性的思路。
