观察了40例糖尿病患者的甲状腺功能变化,并根据是否并发急、慢性并发症将病人分为无并发症组(A组)、急性并发症组(B组)、慢性并发症组(C组)。结果发现:与正常对照组相比,糖尿病患者血清rT_3均值明显增高,血清T_3、T_4、FT_3、FT_4均值及T_3/rT_3比值均明显降低,B、C两组这种变化更为显著,B组并伴有TSH的降低;rT_3与血糖值呈正相关,FT_3、T_3、T_3/rT_3比值与血糖值呈负相关。 Thirty patients with diabetes mellitus were observed for thyroid function changes. Patients were divided into non-complication group (A group), acute complication group (B group) and chronic complication group (C group) according to whether acute and chronic complications occurred. . The results showed that compared with the normal control group, mean serum rT_3 in diabetic patients was significantly increased, meanwhile serum T_3, T_4, FT_3, FT_4 mean values ​​and T_3 / rT_3 ratios were significantly decreased, while those in B and C groups were more significant Accompanied by a decrease of TSH; rT_3 was positively correlated with blood glucose, and the ratio of FT_3, T_3 and T_3 / rT_3 was negatively correlated with blood glucose.
