糖尿病患者血液流变性与甲襞微循环相关性研究

THE STUDY IN HEMORIIEOLOGY AND NAILFOLD MICROCIRCULATION OF DIABETESMELLITUS

目的：研究糖尿病（ＤＭ）患者血液流变与甲襞微循环的相关性。方 法收测３５例糖尿病患者血流变、甲襞微循环及部分生化指标，与３５例正常人对照。结果（１）非胰岛素依赖性糖尿病（ＮＩＤＤＭ）组全血高、低切粘度和高、低切还原粘度及血浆粘度均显著高于对照组（Ｐ＜０．０１～０．００１）．而胰岛素依赖性糖尿病（ＩＤＤＭ）组上述各粘度指标仅轻度增高（Ｐ＞０．０５）；（２）各ＤＭ组及不同并发症亚组均有红细胞刚性指数增高，微循环血流速度减慢，红细胞聚集性增强，白色微血栓等指标显著异常（Ｐ＜０．０５～０．００１）；（３）ＮＩＤＤＭ 组及并发症亚组，微血管畸形数增多，管禅长度增加，微血管周围有明显渗出及出血等形态和管围指标的改变（Ｐ＜０．０５～０．００１）；（４）直线相关分析显示各ＤＭ组全血高切还原粘度与红细胞刚性指数，血浆粘度与甘油三酯水平，微循环内红细胞聚集程度与白色微血栓数量均呈正相关（Ｐ ＜０．０５～０．００１）；空腹血糖与微循环内血流速度呈负相关（Ｐ＜０．０５），ＩＤＤＭ组血浆粘度与全血高、低切粘度、白色微血栓呈正相关（Ｐ＜０．０５）。结论：（１）各型 Ｄ Ｍ 患者均有不同程度血液流变性异常及微循环障碍。（２）Ｄ

obictive: Too investigate on change of hemorheology and nailfold microcirculation in patients with, diabetes mellitus. Method: We determined the parameters of hemorheology and nailfold microcirculation and some biochemical parmeters in 35 diabetics and 35 healthy persons for control. Results: (1)There are abnormal changes of hemorheolohu and microcirculation in every DM grop. (2)there is a significant relationship between hemorheology and microcirculation. (3)Abnormal changs of hemorheology and microcirculation. (3)Abnormal changs of hemorheology and microcirculation were more obvious in NIDDM. Conclusion: The long time hypereglycemia and disorders of metabolism are the reason of the development of the abnormal microcirculation and the chronic complications.
