糖尿病是以慢性高血糖为特征的内分泌代谢性疾病,其突出的病理改变是合并微小血管病变和动脉血管壁的硬化,从而导致各种心、脑、肾血管疾病和视网膜病变的发生。内分泌代谢紊乱和心脑血管病变与血液流变学密切相关。血液流变学是从宏观、微观以至亚微观水平研究血细胞及血浆成分的变形与流动性质,血液流变学指标检测对疾病的诊断有重要意义[1]。研究 Diabetes mellitus is an endocrine and metabolic disease characterized by chronic hyperglycemia. The prominent pathological changes are the combination of micro-vascular lesions and arterial wall sclerosis, which leads to various heart, brain and renal vascular diseases and retinopathy. Endocrine and metabolic disorders and cardiovascular disease and hemorheology are closely related. Hemorheology is the study of the deformation and flow properties of blood cells and plasma components from the macro, micro and sub-micro level, and the detection of hemorrheological indexes is of great significance for the diagnosis of the disease [1]. the study
