目的　研究２型糖尿病合并脑梗死（ｃｅｒｅｂｒａｌ ｉｎｆａｒｃｔｉｏｎ， Ｃ Ｉ）患者的血糖、血脂与血粘度水平。方法　将８０例２型糖尿病合并 Ｃ Ｉ患者、８０例２型糖尿病患者与８０例正常人对照，分别测其空腹血糖、总胆固醇、甘油三酯、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、全血粘度低切、高切和血浆粘度。结果　２型糖尿病合并 Ｃ Ｉ患者的血糖、血脂与血粘度水平均较正常对照组明显增高（ Ｐ ＜ ００１， Ｐ ＜ ００５）；合并 Ｃ Ｉ组患者的血糖、低密度脂蛋白胆固醇及血浆粘度水平较未合并 Ｃ Ｉ的糖尿病组也明显增高 （ Ｐ ＜ ００１， Ｐ ＜ ００５）。结论　糖尿病患者糖代谢紊乱，血脂异常及血流变学异常可能是其易发生 Ｃ Ｉ的主要因素 Objective To study the levels of blood glucose, blood lipid and blood viscosity in type 2 diabetic patients with cerebral infarction (C I). Methods Eighty patients with type 2 diabetes mellitus complicated with C I and 80 type 2 diabetes mellitus were compared with 80 healthy controls. Their fasting blood glucose, total cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein Cholesterol, whole blood low viscosity, high shear and plasma viscosity. Results The levels of blood glucose, blood lipids and blood viscosity in patients with type 2 diabetes mellitus complicated with C I were significantly higher than those in controls (P <001, P <005). The levels of blood glucose and low density lipoprotein Cholesterol and plasma viscosity levels were significantly higher than those without diabetes (P <001, P <005). Conclusions The diabetic patients with abnormal glucose metabolism, dyslipidemia and abnormal hemorheology may be the main factors of C I
