本文观察了２３例单纯性重度肥胖儿童治疗前后血液粘度的变化，同时检测２０例健康儿童作为正常对照。结果：治疗前肥胖组儿童的低、中、高切变率下的全血粘度、血浆粘度、全血还原粘度、红细胞聚集指数（Ａｒｂｃ）、红细胞变形指数（ＴＫ）均明显高于正常对照组，说明单纯性肥胖儿童存在红细胞聚集性增强、变形性下降。治疗３～６个月后，低切变率下的全血粘度较治疗前明显降低，中、高切变率下的全血粘度、血浆粘度、全血还原粘度等均恢复正常。提示早期治疗肥胖、降血脂对于降低血液粘度具有重要意义
In this paper, 23 cases of simple obese children before and after treatment of blood viscosity changes, while testing 20 healthy children as a normal control. Results: The whole blood viscosity, plasma viscosity, whole blood reduced viscosity, erythrocyte aggregation index (Arbc) and erythrocyte deformability index (TK) in obese group before treatment were significantly higher than those in normal control group , Indicating the existence of simple obese children increased erythrocyte aggregation, decreased deformability. After 3 to 6 months of treatment, the whole blood viscosity at low shear rate was significantly lower than that before treatment. The whole blood viscosity, plasma viscosity and whole blood reduction viscosity under medium and high shear rates returned to normal. Prompt early treatment of obesity, lipid-lowering for reducing blood viscosity is of great significance
