2型糖尿病患者血清瘦素与颈动脉内膜中层厚度的相关性研究

目的探讨2型糖尿病（T2DM）患者血清瘦素水平与颈动脉内膜中层厚度（IMT）的关系。方法选择35例2型糖尿病患者、16例正常对照者，分别测定其血清瘦素、空腹血糖、糖化血红蛋白Alc（HbAlc）、C肽、血脂、血压、体重指数（BMI）及腰围，同时使用高分辨率超声检测双侧颈动脉IMT。结果T2DM患者血清瘦素浓度与颈动脉IMT呈显著正相关。结论血清瘦素浓度与颈动脉IMT的增厚有关，提示瘦素可能是导致T2DM患者动脉粥样硬化中的一项危险因素。

Association of serum leptin with intima-media thickness of carotid artery in type 2 diabetes patients

Objective To investigate the relationship between serum leptin and carotid intima-media thickness in patients with type 2 diabetes mellitus. Methods 35 patients with type 2 diabetes mellitus (DM) and 16 normal controls were studied. Fasting serum leptin, fasting glucose(FBG), HbAlc, C-peptide, lipide, systolic(SBP), diastolic blood pressure(DBP), body mass index (BMI) and waist circ-umference (WC) were measured in all subjects. The intima-media thickness (IMT) of common carotid artery was measured by high-resolu-tion ultrasound imaging. Results IMT of T2DM was positively correlated with leptin concentration. Conclusion Serum leptin concentra-tion is independently associated with the IMT of carotid artery, which suggest that leptin may be an independent risk factor of atherosclerosis.
