摘要
(1)目的分析糖尿病甲状腺机能亢进症患者血清胰岛素样生长因子-1(IGF-1)水平的变化及其相关因素。(2)方法选取100例2型糖尿病患者按甲状腺功能水平分为两组:糖尿病组、糖尿病合并甲状腺机能亢进症组,每组各50例。用化学发光法检测血清IGF-1水平的含量,分析其与血糖、胰岛素、甲状腺功能等指标的相关性。(3)结果 2型糖尿病合并甲状腺机能亢进患者血清IGF-1含量低于糖尿病组(P <0.01);血清IGF-1水平与血清中TT3、TT4、FT3、FT4水平呈负相关(r=-0.28,-0.32,-0.37,-0.45,P <0.01),与空腹血糖、餐后2小时血糖、空腹胰岛素、餐后2小时胰岛素、空腹C肽、餐后2小时C肽、促甲状腺激素(TSH)含量呈正相关(r=0.86,0.27,0.64,0.53,0.57,0.47,0.46,P<0.05)。(4)结论糖尿病患者发生甲状腺机能亢进症血清IGF-1下降,与甲状腺激素水平呈负相关变化。
Objective To analyze the changes of serum insulin-like growth factor(IGF-1)and its related factors in diabetic patients with hyperthyroidism.Methods A total of 100 patients with type 2diabetes were divided into two groups according to the level of thyroid function:diabetic group,diabetic group combined with hyperthyroidism group,50 patients in each group.The content of serum IGF-1level was detected by chemiluminescence method,and its correlation with blood glucose,insulin and thyroid function was analyzed.Results The serum IGF-1content of type 2diabetes mellitus with hyperthyroidism was lower than that of diabetes group(P <0.01).Serum levels of IGF-1and serum TT3,TT4,FT3,FT4 levels showed a negative correlation(r =0.28,0.32,0.27,0.28,P <0.01),and fasting glucose,2hpostprandial blood glucose,fasting insulin,2hpostprandial insulin,fasting C peptide,2hpostprandial C-peptide,TSH levels were positively correlated(r=0.86,0.27,0.64,0.53,0.57,0.47,0.46,P <0.05).Conclusion Serum IGF-1decreased in diabetic patients with hyperthyroidism.
