摘    要:目的研究血清性激素结合球蛋白与2型糖尿病患者大血管病变的关系及其可能机制。方法入选2010年1月至2011年12月在我院老年内分泌科门诊及住院部就诊的80例2型糖尿病患者男48例,女32例,平均年龄(61±8)岁],根据是否合并大血管病变分为未合并大血管病变组B组,n=40,男23例,女17例,平均年龄(60±11)岁]和合并大血管病变组C组,n=40,男25例,女15例,平均年龄(63±11)岁]。另以同期在我院进行健康体检者40名为健康对照组A组,男25名,女15名,平均年龄(58±10)岁]。测定和计算3组受试者血清性激素结合球蛋白水平、体质指数、腰臀比、血压、血脂、糖化血红蛋白、空腹及餐后血糖、血清胰岛素、尿蛋白/肌酐比值、胰岛素抵抗指数。2组问均数比较采用t检验,3组问均数比较采用方差分析,性激素结合球蛋白相关因素分析采用Spearman相关分析和逐步线性回归分析。结果C组血清性激素结合球蛋白水平(31±6)u/L]明显低于B组(46±17)u/L]及A组(56±14)阻∥L](F=9.763,P〈0.01)。Spearman相关分析显示,血清性激素结合球蛋白水平与腰臀比、甘油三酯、空腹及餐后胰岛素水平、胰岛素抵抗指数、尿蛋白/肌酐比值呈负相关(r值分别为-0.216、-0.156、-0.144、-0.108、-0.263、-0.126,均P〈0.05)。多元逐步回归分析表明,血清性激素结合球蛋白水平与甘油三酯、腰臀比、胰岛素抵抗指数具有直线回归关系(r2值分别为-1.132、-0.862、-2.650,均P〈0.05)。非条件logistic回归分析显示,血清性激素结合球蛋白水平对大血管病变具有-定影响。结论血清性激素结合球蛋白可能作为危险因素参与2型糖尿病及其大血管病变的发生和发展。

Abstract:Objective To investigate the relationship between serum sex hormone-binding globulin (SHBG) and macrovascular complications in patients with type 2 diabetes mellitus (T2DM). Methods A total of 80 T2DM patients (male 48, female 32, average age (61 -+ 8) y) who were admitted to our hospital during January 2010 and December 2011 were assigned to the macrovascular complication group (group C, n =40, male 25, female 15, average age (63 + 11 ) y) and non-macrovascular complication group (group B, n = 40, male 23, female 17, average age (60 + 11 ) y), Another 40 healthy controls were recruited from health check-up populations (group A, male 25, female 15, average age (58 ~ 10) y). Serum SHBG, body mass index (BM), waist/hip ratio (WHR), fasting and postprandial plasma glucose, serum insulin, hemoglobin A1 c (HbA1 c), lipids, blood pressure, urinary albumin to creatinine ratio (ACR), and insulin resistance were measured. Student's t test or Analysis of variance was used for data analysis. Results Serum level of SHBG in group C ( (31 -+6) Ixg/L) was significantly lower than that in group B ( (46 _+ 17) txg/L) and group A ( (56 -+ 14) tzg/L) (F = 9. 763, P 〈 0. 01 ). In Speal~nan correlation analysis, serum SHBG was negatively correlated with WHR, triglyceride (TG), fasting and postprandial serum insulin, insulin resistance index (IRI) and ACR (r values were -0. 216, -0. 156, -0. 144, -0. 108, -0. 263and -0. 126, respectively; all P 〈 0. 05). Multiple stepwise regression analysis showed that TG, WHR and IRI were independent variables of serum SHBG (r2 values were - 1. 132, - 0. 862 and - 2. 650, respectively ; all P 〈 0. 05 ). Conclusions Serum SHBG seems to play an important role in the deve|opment of type 2 diabetic macrovascular complications.
