目的研究甲状腺功能亢进与糖代谢紊乱、胰岛素β细胞功能异常、胰岛素抵抗的关系。方法选取我院2015年6月至2016年6月收治的48例甲状腺功能亢进患者为甲亢组,及同期在我院行健康体检的40例健康者作为对照组。检测并比较两组受检者的空...目的研究甲状腺功能亢进与糖代谢紊乱、胰岛素β细胞功能异常、胰岛素抵抗的关系。方法选取我院2015年6月至2016年6月收治的48例甲状腺功能亢进患者为甲亢组,及同期在我院行健康体检的40例健康者作为对照组。检测并比较两组受检者的空腹胰岛素(Fins)、餐后2 h胰岛素(2 h INS)、空腹血糖(FPG)、餐后2 h血糖(2 h PG)、糖化血红蛋白(Hb Alc)、游离甲状腺原氨酸(FT3)、游离甲状腺素(FT4)、促甲状腺激素(TSH)水平,并计算胰岛素抵抗指数(HOMA-IR)、胰岛素敏感指数(ISI)、胰岛β细胞功能(HOMA-IS)。结果甲亢组患者出现糖耐量异常23例,占47.92%,10例糖耐量异常诊断达到糖尿病标准,占20.83%;甲亢组患者的FT3、FT4水平分别为(23.2±6.1)pmol/L、(61.2±20.4)pmol/L,均明显高于对照组,TSH水平为(0.21±0.11)u IU/m L,明显低于对照组,差异均有统计学意义(P<0.05);甲亢组患者的FPG、2 h PG、Hb Alc水平分别为(5.51±0.52)mmol/L、(8.92±1.77)mmol/L、(8.10±1.82)%,均明显高于对照组,差异均有统计学意义(P<0.05);甲亢组患者的2 h INS、HOMA-IR水平分别为(51.3±8.5)m U/L、(1.41±0.33),均较对照组显著升高,HOMA-IS、ISI水平分别为(1.41±0.33)、(-3.90±0.22),均较对照组显著降低,差异均有统计学意义(P<0.05);FT3与HOMA-IR呈正相关(r=0.908,P<0.05),FT4、TSH与HOMA-IR无显著相关性(r=-0.036、-58.755,P>0.05)。结论甲状腺功能亢进患者普遍存在糖代谢紊乱、胰岛β细胞损伤和胰岛素抵抗,且FT3与HOMA-IR有正相关性。展开更多

METHODS： Cross-sectional study. A total of 1466 subjects with T2DM were recruited in a local Desheng Community of urban Beijing from November 2009 to June 2012 for the cohort of Beijing Desheng Diabetic Eye Study. Standardized evaluation was carried out for each participant, including questionnaire, ocular and anthropometric examinations, and laboratory tests. Seven fields 30° color fundus photographs were used for DR grading according to the Early Treatment Diabetic Retinopathy Study protocols. Homeostatis Model Assessment （HOMA） method was employed for IR and β-cell function assessment. RESULTS： After excluding those participants who were treated with insulin （n=352） or had missing data of fasting insulin （n=96）, and further excluding those with poor quality of retinal photographs （n=10）, a total of 1008 subjects were included for the final analysis, 406 （40.3%） were men and 602 （59.7%） were women, age ranging fiom 34 to 86 （64.87±8.28）y. Any DR （levels 14 and above） was present in 278 （27.6%） subjects. After adjusting for possible covariates, the presence of any DR did not correlate with HOMA IR [odds ratio （OR） 1.51, 95% confidence interval （Cl） 0.87-2.61, P=0.14] or HOMA β-cell （OR 0.71, 95%CI 0.40-1.26, P=0.25）. After stratification by BMI, the presence of any DR was associated positively with HOMA IR （OR 2.46, 95%CI： 1.18-5.12, P=0.016）, and negatively with HOMA β-cell （OR 0.40, 95%CI： 0.19-0.87, P=0.021） in the group of patients with higher BMI （225 kg/m2）. In the group of patients with lower BMI （〈25 kg/m2）, the presence of any DR was not associated with HOMA IR （OR 1.00, 95%C1： 0.43-2.33,展开更多
