摘要

背景：重度肥胖和2型糖尿病患者的L细胞分泌肠促胰岛素减少。研究表明，L细胞活性的增加与胆胰环（BPL）的长度有关。目的：比较胆胰袢延长对RYGB患者L细胞数量和表达的影响。方法：BPL为100 cm （G1）和200 cm （G2）的RYGB患者（n = 13）。在RYGB术前（T1）和术后（T2） 6个月分别对胃-肠吻合处(A)、肠-肠吻合处(B)和回肠末端(C) 3段进行肠道活检。采用免疫组织化学和qRT-PCR对肠道活检结果进行分析。结果：T1组（17±10.5）与T2组（23.5±10.7）仅在c点PYY和GLP1标记的L细胞表达量升高（p < 0.0001）， G1组与G2组在A点L细胞表达量差异无统计学意义(A1: 17.3±2.9；A2: 19.9±1.9；p = 0.09), B (B1: 13.7±6.6；B2: 14.1±4.9；p = 0.89)和C (C1: 13.2±2.2；C2: 11.4±3.4；p = 0.32)在PYY和GLP1基因表达中的差异(A1: 20.8±4,1；A2: 23.7±3.6；p = 0.2), B (B1:14.3±7.9；B2: 22.7±11.8；p = 0.1), (C1: 17±4.1；C2: 21.1±4.8；P = 0.2)。结论：两种方法均可增加活性L细胞的数量。

Evaluation of l-cell activity in the small intestine according to the extension of the biliopancreatic loop in patients undergoing Roux-en-Y gastric by-pass

Background

Individuals with severe obesity and type 2 diabetes mellitus have reduced secretion of incretins by L cells. Studies suggest an increase in L cell activity according to the length of the Biliopancreatic Loop (BPL).

Objective

Compare the effect of biliopancreatic loop extension on the number and expression of L cells in patients undergoing RYGB

Methods

Subjects (n = 13) undergoing RYGB with a BPL of 100 cm (G1) or 200 cm (G2). Intestinal biopsies were done before (T1) and 6 months after (T2) RYGB in 3 segments: gastro-enteric anastomosis (A), entero-enteric anastomosis (B) and terminal ileum (C). Analyzes of intestinal biopsies by immunohistochemistry and qRT-PCR.

Results

There was an increase (p < 0.0001) in L cells marked by PYY and GLP1 between T1 (17 ± 10.5) and T2 (23.5 ± 10.7) only at point C. There was no difference in L cells expression between groups G1 and G2 at points A (A1: 17.3 ± 2.9; A2: 19.9 ± 1.9; p = 0.09), B (B1: 13.7 ± 6.6; B2: 14.1 ± 4.9; p = 0.89) and C (C1: 13.2 ± 2.2; C2: 11.4 ± 3.4; p = 0.32) in PYY and GLP1 gene expression (A1: 20.8 ± 4, 1; A2: 23.7 ± 3.6; p = 0.2), B (B1:14.3 ± 7.9; B2: 22.7 ± 11.8; p = 0.1), (C1: 17±4.1; C2: 21.1 ± 4.8; p = 0.2).

Conclusions

Both techniques lead to an increase in the number of active L cells.
