研究目的: |
1. 主要目的: (1)比较T2DM患者与健康对照者十二指肠粘膜中K细胞的密度与GIP表达水平的差异。 (2)比较T2DM患者与健康对照者外周血浆GIP浓度水平的差异。 (3)比较T2DM患者与健康对照者经鼻内胰岛素激发后下丘脑胰岛素敏感性(通过功能性磁共振成像fMRI量化)的差异。 2. 次要目的: (1)分析T2DM患者十二指肠粘膜转录组特征,探索与代谢紊乱相关的差异表达基因通路。 (2)探究T2DM患者中,十二指肠K细胞特征(密度/GIP表达)、外周血GIP水平与下丘脑胰岛素敏感性指标之间的相关性。 |

Objectives of Study: |
1. Primary Objectives:(1) To compare the density of K cells and the expression levels of Gastric Inhibitory Polypeptide (GIP) in the duodenal mucosa between patients with Type 2 Diabetes Mellitus (T2DM) and healthy controls.(2) To compare the differences in peripheral plasma GIP concentration levels between patients with T2DM and healthy controls.(3) To compare the differences in hypothalamic insulin sensitivity—quantified via functional magnetic resonance imaging (fMRI)—between patients with T2DM and healthy controls after intranasal insulin stimulation. 2. Secondary Objectives:(1) To analyze the transcriptomic profile of the duodenal mucosa in patients with T2DM and explore differentially expressed gene pathways associated with metabolic disturbances.(2) To investigate the correlations among duodenal K?cell characteristics (density/GIP expression), peripheral blood GIP levels, and hypothalamic insulin sensitivity indices in patients with T2DM. |
