| \[摘要\]目的对比Roux-en-Y胃转流术及胆胰分流术治疗大鼠非肥胖2型糖尿病的疗效。方法48只雄性Goto-Kakizaki (GK) 大鼠随机分为Roux-en-Y胃转流术(Roux-en-Y gastric bypass,RYGBP)、胆胰分流术(billiopancreatic diversion,BPD)和假手术组,每组16只。检测术前及术后1、3、6、9、12、24周空腹血糖、胰岛素水平,检测术前及术后6、12、24周糖化血红蛋白,计算胰岛素抵抗指数(HOMA-IR),观察术后各组死亡率和并发症。结果术后1～24周Roux-en-Y胃转流术、胆胰分流术组空腹血糖显著降低(P<0.05，P<0.01),术后12、24周糖化血红蛋白显著降低(P<0.01)；假手术组上述指标均未见显著变化。各组空腹胰岛素水平差异无统计学意义。与术前相比,Roux-en-Y胃转流术组和胆胰分流术组术后1～24周HOMA-IR指数显著降低(P<0.05)；同时间点两组间比较,术后1～24周胆胰分流术组HOMA-IR指数显著低于Roux-en-Y胃转流术组(P<0.05)。Roux-en-Y胃转流术组死亡率为6%,胆胰分流术组死亡率达50%,胆胰分流术组术后并发症及死亡率均高于Roux-en-Y胃转流术组(P<0.05)。结论Roux-en-Y和胆胰分流术治疗大鼠非肥胖2型糖尿病疗效相近,但胆胰分流术术后并发症和死亡率高于Roux-en-Y胃转流术。 |

| Abstract: |
| \[Abstract\]ObjectiveTo compare the efficacies of Roux-en-Y gastric bypass (RYGBP) and billiopancreatic diversion(BPD) in treatment of rats with non-obese type 2 diabetes mellitus. MethodsTotally 48 Goto-Kakizaki rats were randomized to undergo one of the following procedures: Roux-en-Y gastric bypass(n=16), biliopancreatic diversion(n=16), and sham operation (n=16). The fasting blood glucose and fasting insulin were determined before and 1, 3, 6, 9, 12, and 24 weeks after operation; the hematoglobin A1c (HbA1c) levels were determined before and 6, 12, and 24 weeks after operation and the insulin resistance index (HOMA-IR) was calculated. The mortality and complications were observed in each group. ResultsThe fasting blood glucose levels were significantly decreased during 1-24 weeks after operation in both Roux-en-Y group and biliopancreatic diversion group(P<0.01 or P<0.05); the HbA1c levels were also decreased 12 and 24 weeks after operation (P<0.01); and the above parameters were not significantly changed in the sham operation group. The fasting insulin levels were not significantly different between the 3 groups. In RYGBP group and the BPD group, the HOMA-IR indices decreased significantly 1-24 weeks after operation compared with those before operation (P<0.05), and those in the BPD group were significantly lower than those in the RYGBP group at all time points (P<0.05). The mortality was 6% in the RYGBP group and 50% in the BPD group. The complication rate and mortality in the BPD group were significantly higher than those in the RYGBP group (P<0.05). ConclusionRYGBP and BPD have similar efficacies in treatment of rats with non-obese type 2 diabetes mellitus, and BPD can lead to higher incidences of complications and mortalities than RYGBP. |
