摘 要:目的探讨浅低温不停跳心脏瓣膜置换手术对空腹血糖受损患者胰岛素抵抗及免疫功能的影响。方法选取2011年3月至2014年3月于商丘市第一人民医院行心脏瓣膜置换手术的风湿性心脏病空腹血糖受损患者67例,采取抛掷硬币的方式随机分为停跳组(32例,中度低温心脏停跳情况下完成手术)和不停跳组(35例,浅低温心脏跳动中完成瓣膜置换手术),比较2组患者T1(术前)、T2(体外循环转机30min)、T3(体外循环停机即刻)、T4(术毕)、T5(术后2h)、T6(术后24h)、T2(术后3d)的血糖、胰岛素、胰岛素抵抗指数(HOMA—IR)、免疫球蛋白(Ig)A、IgG、IgM的变化情况。结果T2-T6时点2组患者血糖、胰岛素、HOMA—IR均高于T1时点[停跳组血糖:(10.6±1.3)、(13.1±2.1)、(12.1±1.6)、(10.7±1.5)、(8.2±0.9)mmo]/L比(6.3±0.6)mmol/L,胰岛素:(6.9±0.9)、(9.1±1.3)、(7.9±1.2)、(7.2±1.2)、(6.9±1.2)mIU/L比(4.9±0.8)mIU/L,HOMA—IR:(3.8±1.2)、(4.9±1.1)、(4.2±1.1)、(3.2±0.8)、(2.3±0.8)比(1.4±0.7);不停跳组血糖:(9.2±1.0)、(11.0±1.6)、(10.8±1.3)、(8.3±1.0)、(6.6±0.7)mmol/L比(6.3±0.5)mmol/L,胰岛素:(6.1±1.0)、(7.8±1.3)、(6.5±1.1)、(6.1±1.2)、(5.7±1.2)mIU/L比(4.9±0.5)mIU/L,HOMA—IR:(2.6±1.0)、(3.8±0.8)、(3.2±0.8)、(2.4±0.7)、(1.8±0.6)比(1.4±0.7)],差异均有统计学意义(均P〈0.05),且同时点不停跳组明显低于停跳组,差异有统计学意义(P〈0.05)。T2~T6时点2组患者IgA、IgG、IgM值均明显低于T。时点[停跳组IgA:(1.5±0.4)、(1.7±0.6)、(1.9±0.7)、(1.9±0.7)、(2.0�Objective To explore the influence of valve replacement on beating heart under mild hypothermia on insulin resistance and immune function in patients with impaired fasting glucose. Methods Totally 67 rheumatic heart disease patients with impaired fasting glucose who underwent valve replacement on beating heart under mild hypothermia from March 2011 to March 2014 were were randomly divided into arrest group (32 cases) and beating group (35 cases). Patients in arrest group underwent valve replacement on arrested heart under moderate hypothermia, while patients in beating group underwent heart valve replacement on beating heart under mild hypothermia: The changes of blood glucose, insulin, insulin resistance index (HOMA-IR), immunoglobulin (Ig) A, IgG, and IgM before operating ( T1 ) , 30 rain after cardiopulmonary bypass ( T2 ) , immediately after cardiopulmonary bypass stopped ( T3 ), immediately after operation completed ( T4 ), 2 h (T5 ), 24 h ( T6 ) and 3 d (T7 ) after operation were compared between groups. Results At T2-T6 time points, the levels of blood glucose, insulin, HOMA-IR were significantly higher than those at T1 time point in arrest group [ blood glucose : ( 10. 6 ± 1.3 ) , (13. 1 ±2. 1), (12. 1 ±1.6), (10.7±1.5), (8.2±0.9) mmol/L vs (6.3 ±0.6) mmol/L; insulin: (6.9± 0.9), (9.1±1.3), (7.9±1.2), (7.2±1.2), (6.9±1.2) mlU/L vs (4.9 ±0.8) mlU/L; HOMA-IR: (3.8±1.2), (4.9±1.1), (4.2±1.1), (3.2±0.8), (2.3±0.8) vs (1.4±0.7)] and beating group [blood glucose: (9.2±1.0), (11.0±1.6), (10.8 ±1.3), (8.3±1.0), (6.6 ±0.7) mmol/Lvs (6.3 ± 0.5) mmol/L; insulin: (6.1 ±1.0), (7.8 ±1.3), (6.5 ±1.1), (6.1 ± 1.2), (5.7 ±1.2) mlU/L vs (4.9±0.5) mlU/L; HOMA-IR: (2.6±1.0), (3.8±0.8), (3.2±0.8), (2.4±0.7), (1.8±0.6) vs ( 1.4 ± 0. 7 ) ] ( P 〈 0. 05 ) ; they were all significantly lower
