摘要目的 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型糖尿痛患者、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AIc(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.

abstractsObjective 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.
