摘    要:目的 探讨胃袖状切除术对2型糖尿病大鼠糖脂代谢的作用.方法 将24只11周龄的Goto-Kakizaki大鼠按随机数字表法分为空白组(不进行任何手术,仅保持相同进食)、假手术组(仅与手术组对应位置切开缝合)和手术组(胃袖状切除术),每组8只;分别检测各组大鼠各时相点体质量、进食量、糖代谢、激素和脂代谢变化情况.多组比较采用方差分析,两两比较采用LSD检验.结果 术后6周,空白组大鼠体质量、进食量分别为(320±12)g、(25.1±0.8)g,假手术组分别为(318±12)g、(25.5 ±1.3)g,手术组分别为(299±9)g、(21.9±1.3)g,3组比较,差异有统计学意义(F=8.50,10.02,P<0.05).术后16周,空白组大鼠空腹血糖、葡萄糖耐量试验曲线下面积、胰岛素耐量试验曲线下面积、胰岛素抵抗指数、饥饿素、游离脂肪酸、瘦素分别为(11.4±1.1) mmol/L、(3 220±460) mmol/L·min-1、(2 317±715)mmol/L·min-1、4.2±0.4、(1 513±75) ng/L、(2.16±0.20) μg/L、(6.2±0.8)μg/L,假手术组分别为(12.9±1.3) mmol/L、(3 554±272) mmol/L· min-1、(2 078±367)mmol/L· min-1、4.2±0.8、(1 510±72) ng/L、(1.95±0.31) μg/L、(6.3±0.7) μg/L,手术组分别为(5.5 ±0.3)mmol/L、(2 077±221)mmol/L·min-1、(946±330) mmol/L·min-1、2.2±0.5、(986±75) ng/L、(1.44±0.13) μg/L、(2.5±0.7)μg/L,3组比较,差异有统计学意义(F =84.19,7.33,9.93,18.81,99.79,79.02,238.30,P<0.05).术后16周葡萄糖灌胃后60 min,空白组大鼠血清胰高血糖素样肽-1、酪酪肽、胰岛素、脂连素分别为(11.3±2.3)pmol/L、(70±13) ng/L、(7.8±1.0)mIU/L、(4.9±1.2) μg/L;假手术组分别为(11.2±1.7) pmol/L、(72±14) ng/L、(9.9±1.9) mIU/L、(5.0±0.9)μg/L;手术组分别为(14.7±2.4) pmol/L、(128±20) ng/L、(21.7±2.1)mIU/L、(7.8±1.1) μg/L,3组比较,差异有统计学意义(F=4.22,20.91

Abstract:Objective To investigate the regulatory effects of sleeve gastrectomy on the glucose and lipid metabolism in rats with type 2 diabetes mellitus.Methods Twenty-four Goto-Kakizaki rats aged 11 weeks were randomly divided into the blank group (the rats did not receive any surgical procedures),sham operation group (the rats received abdominal incision and suture at the same site as the rats in the operation group) and operation group (the rats received sleeve gastrectomy).There were 8 rats in each group.The changes of the body weight,food intake,glucose and lipid metabolism and gastrointestinal hormones were measured at different time points after operation.All data were analyzed using the analysis of variance or LSD test.Results In postoperative week 6,the body weights and food intake were decreased to (320 ± 12)g and (25.1 ±0.8)g in the blank group,(318 ± 12)g and (25.5 ± 1.3)g in the sham operation group,(299 ±9)g and (21.9 ± 1.3)g in the operation group.There were significant differences in the body weight and food intake between the 3 groups (F =8.50,10.02,P < 0.05).In postoperative week 16,the levels of fasting glucose,the areas under the curve of the oral glucose tolerance test and insulin tolerance test,index of insulin resistance,ghrelin,free fatty acides and leptin were (11.4 ±1.1) mmol/L,(3 220±460) mmol/L · min-1,(2 317 ±715)mmol/L · min-1,4.2 ±0.4,(1 513 ±75)ng/L,(2.16 ±0.20) μg/L,(6.2 ±0.8) μg/L in the blank group,(12.9 ± 1.3) mmol/L,(3 554 ± 272) mmol/L · min-1,(2 078 ±367) mmol/L · min-1,4.2 ±0.8,(1 510±72)ng/L,(1.95 ± 0.31) μg/L,(6.3 ±0.7)μg/L in the sham operation group,(5.5 ± 0.3) mmol/L,(2 077 ± 221) mmol/L · min-1,(946 ± 330) mmol/L ·min-1,2.2 ± 0.5,(986 ± 75) ng/L,(1.44 ± 0.13) μg/L and (2.5 ± 0.7) μg/L in the operation group.There were significant differences in the fasting glucose,the areas under the curve of the oral glucose tolerance test an
