摘要 目的探讨FTO基因对腹腔镜Roux-en-Y胃旁路术(laparoscopic Roux—en—Y gastric bypass,LRYGB)治疗2型糖尿病(type 2 diabetes mellitus,T2DM)患者疗效的影响。方法选择2014年1月至2015年6月在北京世纪坛医院接受LRYGB治疗的32例T2DM患者,检测FTOrs9939609基因单核苷酸多态性,并分为两组:A组(20例),TT基因型;B组(12例),AT和AA基因型。结果术后12个月,A组患者随着BMI由术前(36.4±3.3)kg/m^2降到(28.1±2.8)kg/m^2,空腹血糖和HbA1c较术前明显改善[(8.9±1.6)mmo/L比(5.6±1.2)mmol/L,t=8.274,P=0.000;(8.5%±1.9%)比(6.2%±0.8%),t=5.032,P=0.000]:B组患者随着BMI由术前(39.5±5.6)kg/m^2降到(29.7±5.1)kg/m^2,空腹血糖和HbA1c较术前明显改善[(10.8±2.8)mmol/L比(4.9±0.6)mmol/L,t=7.589,P=0.000;(9.0%±1.8%)比(6.1%±0.9%),t=5.324,P=0.000]。2组术后的胰岛素抵抗指数较术前改善[(12.6±10.7)比(4.9±5.6),t=5.402,P=0.000;(16.0±5.6)比(1.7±1.3),t=9.025,P=0.000]。B组患者的术后空腹血糖和胰岛素抵抗指数低于A组患者(P〈0.05)。结论FTO rs9939609基因表型为AT和AA的T2DM患者LRYGB手术疗效更好。 Objective To investigate the effect of FTO gene on laparoscopic Roux-en-Y gastric bypass for type 2 diabetes. Methods From Jan 2014 to 2015 Jun, 32 T2DM patients received LRYGB in Beijing Shijitan Hospital. According to single nucleotide polymorphism of FTO rs9939609 gene, patients were divided into TT genotype (20 cases), and AT/AA genotype ( 12 cases). Results Following the degression of BMI from ( 36. 4 ±3.3 ) kg/m^2 to ( 28. 1 ± 2. 8 ) kg/m^2, fasting blood glucose and HbAI c in group A significantly improved [ ( 8.9 ±1.6 ) mmoL/L vs. ( 5.6 ±1.2 ) mmol./L, t = 8.274, P = 0. 000 ; (8.5% ±1.9%) vs. (6.2% ±0.8%), t=5.032, P=0.0001. Following the degression of BMI from (39. 5±5.6) kg/mz to (29. 7 ±5. 1 ) kg/m^2, fasting blood glucose and HbAlc in group B significantly improved [ ( 10. 8 ±2. 8) mmol/L vs. ( 4.9 ±0. 6) mmol/L, t = 7. 589, P = 0. 000 ; ( 9.0% ±1.8% ) vs. (6. 1% ±0. 9% ),t = 5. 324, P = 0. 0001. Insulin resistance index in both groups significantly improved [(12.6±10.7) vs. (4.9±5.6), t=5.402, P=0.000; (16.0±5.6) vs. (1.7±1.3), t=9.025,P= 0. 000 ]. Fasting blood glucose and the insulin resistance index in group B patients was significantly lower than that in group A patients (P 〈 0. 05 ) . Condusion T2DM patients with FTO rs9939609 gene phenotype AT/AA have better prognosis than those with TT in postoperative diabetes improvement.
