摘 要:目的探讨1,25-二羟维生素D_3水平与2型糖尿病(T2DM)患者糖化血红蛋白(Hb A1c)水平以及胰岛素抵抗的相关性。方法选择2013年5月至2014年6月延安市人民医院确诊的80例T2DM患者为研究对象(病例组),并根据1,25-二羟维生素D_3水平,将患者分为严重缺乏组(22例)、缺乏组(27例)以及不足组(31例),选择同期进行体检的80例健康志愿者作为对照组。比较1,25-二羟维生素D_3、Hb A1c水平、胰岛素抵抗指标以及1,25-二羟维生素D_3不同缺乏程度者肾功能及神经功能的损伤程度。结果病例组患者血清1,25-二羟维生素D_3水平低于对照组[(16.3±0.9)ng/L比(38.1±3.3)ng/L,t=16.691,P<0.01],其Hb A1c、胰岛素水平、胰岛素抵抗指数(HOMA-IR)高于对照组[(8.1±0.9)%比(4.4±0.6)%、(13.0±1.5)m U/L比(7.2±0.8)m U/L,(6.1±0.8)比(3.2±0.4),均P<0.01],稳态模型评价胰岛β细胞功能指数(HOMA-β)、胰岛素敏感指数(ISI)均低于对照组[(73.5±9.1)比(162.3±21.4),(0.4±0.1)比(0.6±0.1),均P<0.01]。1,25-二羟维生素D_3与HOMA-IR、Hb A1c、胰岛素呈负相关(r=-0.878,-0.823,-0.796,P<0.05),与HOMA-β、ISI呈正相关(r=0.748,0.738,P<0.05)。1,25-二羟维生素D_3严重缺乏组、缺乏组以及不足组胱抑素C、β2微球蛋白(β2-MG)以及运动神经传导速度(MCV)、感觉神经传导速度(SCV)分别为(1.4±0.2)mg/L、(1.1±0.2)mg/L、(0.8±0.1)mg/L,(2.6±0.3)mg/L、(1.9±0.2)mg/L、(1.4±0.2)mg/L,(22.6±3.4)m/s、(31.5±4.8)m/s、(39.5±5.3)m/s,(25.3±4.0)m/s、(33.2±4.4)m/s、(40.4±5.8)m/s,其中严重缺乏组患者胱抑素C、β2-MG水平显著高于缺乏组和不足组,MCV、SCV显著低于缺乏组和不足组,而缺乏组胱抑素C、β2-MG水平显著高于不足组,而MCV、SCV显著低于不足组,差异有统计学意义(P<0.01)。结论 T2DM患者1,25-二羟维生素D_3水平与Hb A1c水平、胰岛素抵抗相关指标具有良好的相关性,其是造成靶器官功能损伤的重要途径。Objective To study the correlation of 1,25-( OH )2-vitamin D3 expression level and glycated hemoglobin (HbA1c) levels, insulin resistance of type 2 diabetes mellitus (T2DM) patients. Methods Total of 80 T2DM patients in Yan'an People's Hospital from May 2013 to Jun. 2014 were enrolled in the pathological group. According to the level of 1,25-( OH)2-vitamin D3, the patients were divided into severe deficiency group ( 22 cases ), deficiency group ( 27 cases ) and inadequate group ( 31 cases), and 80 healthy volunteers for health examination during the same period were enrolled in the control group. The 1,25- ( OH )2-vitamin D3 , HbA1c levels, insulin resistance index and the degree of injury of renal function and nerve function with different degrees of 1,25-(OH) 2-vitamin D3 deficiency were detected and compared. Results The serum 1,25- (OH) 2-vitamin D3 level of the pathological group was lower than the control group [ ( 16. 3 ± 0. 9) ng/L vs ( 38. 1 ± 3.3 ) ng/L, t = 16. 691, P 〈 0. 05 ], the HbAlo, F/NS, HOMA-IR were higher than the control group [ ( 8. 1 ± 0. 9 ) % vs (4. 4 ± 0. 6 ) %, ( 13.0 ± 1.5 ) mlU/L vs (7.2 ± 0. 8 ) mlU/L, (6. 1 ± 0.8 ) vs (3.2 ± 0.4 ), P 〈 0.01 ]. HOMA-β, ISI were lower than the control group [(73.5 ±9.1) vs (162.3±21.4),(0.4±0.1) vs (0.6±0.1),P〈0.01]. HOMA-IR,HbA±c and insulin were negatively correlated with 1,25-(OH) 2-VitD3 ( r = - 0. 878, - 0. 823, - 0. 796, P 〈 0.05 ), HOMA13, ISI were positively correlated with 1,25- (OH) 2-VitD3 ( r = 0. 748,0. 738, P 〈 0. 05 ). The cystatin C, 132-MG levels and motor nerve conduction velocity ( MCV ), sensory nerve conduction velocity (SCV) of the severe deficiency group, deficiency group and inadequate group were ( 1.4 ± 0. 2 ) mg/L, (1.1±0.2) mg/L,(0.8 ±0.1) mg/L;(2.6 ±0.3) mg/L,(1.9±0.2) mg/L,(1.4 ±0.2) mg/L; (22.6±3.4) m/s,(31.5 ±4.8) m/s,(39.5 ±5.3) in/s;(
