研究目的: |
1.设计内镜下新的肠道菌群取样方法。 2.基于16SrDNA基因扩增子技术,进一步阐述MAFLD脂肪肝患者和健康人员的菌群特征及差异。 3.基于菌群结果,分析其与胆汁酸-FxR调节宿主脂质代谢和胰岛素抵抗的潜在机制。 |
||||||||||||||||||||||
|
Objectives of Study: |
1. Design a new sampling method by endoscopy. 2. Based on the 16S rDNA gene amplicon technology, the characteristics of MAFLD patient's microbiota were further elaborated. 3. Based on the results of microbiota, the potential mechanism of its regulation of host lipid metabolism and insulin resistance with bile acid-FxR was analyzed. |
