摘要
目的
     本研究是通过观察川崎病(Kawasaki disease, KD)患儿循环内皮细胞(CEC)水平的变化与患儿冠状动脉损伤的关系,进一步探讨川崎病早期诊断的方法。
     方法
     研究对象为30例川崎病患儿,其中23例为完全型川崎病,7例不完全型川崎病。采用双盲对照研究法分别于人血丙种球蛋白(IVIG)治疗前抽取静脉血2ml,采用Hladovec法计数循环内皮细胞。根据超声心动图检查结果将川崎病组又分为冠状动脉损伤组(CAL)9例和冠状动脉无损伤组(NCAL)21例。对照组为10例健康体检儿童。
     结果
     川崎病组与对照组CEC数量比较:川崎病组CEC数量为(9.77+5.45)/0.9ul,高于正常对照组的(3.40+1.26)/0.9ul,差异有统计学意义(P<0.01)。
     川崎病CAL组与NCAL组CEC数量比较:CAL组患儿CEC数量为(16.56+2.13)/0.9ul,高于NCAL组的(6.86+3.41)/0.9ul,相比差异有统计学意义(P<0.05)。
     完全型川崎病组和不完全型川崎病组循环内皮细胞数量比较:完全型川崎病组患儿CEC数量为(10.48±5.69)/0.9ul,不完全型川崎病组患儿CEC数量为(7.43+4.08)/0.9ul,两组比较无显著差异(P>0.05)。
     结论
     川崎病急性期患儿循环内皮细胞水平升高明显,急性期冠状动脉损伤组循环内皮细胞水平高于无损伤组,循环内皮细胞水平的检测有助于川崎病的早期诊断。
Objective
     Kawasaki disease in this study by observation (Kawasaki disease, KD) in children with circulating endothelial cells (CEC) levels in patients with coronary artery damage in children, to further explore methods of early diagnosis of Kawasaki disease.
     Methods
     The subjects were 30 cases of children with Kawasaki disease,23 cases of complete disease,7 cases of incomplete Kawasaki disease. Double-blind control study using human blood were gamma globulin (IVIG) treatment before blood samples were 2ml, with Hladovec method to count circulating endothelial cells. According to results of echocardiography will be Kawasaki disease were divided into groups of coronary artery lesions (CAL) 9 cases and coronary artery without injury group (NCAL) 21 cases. Control group of 10 healthy children.
     Results
     Kawasaki disease were compared with the control group, the number of CEC: CEC quantity of Kawasaki disease group (9.77±5.45)/0.9ul, higher than the control group (3.40±1.26)/0.9ul, the difference was significant (P<0.01).
     Kawasaki CAL group compared with the number of CEC NCAL Group:CAL group The number of children with CEC (16.56±2.13)/0.9ul, higher than the NCAL group (6.86±3.41)/0.9ul, compared to significantly (P<0.05).
     Of complete and incomplete Kawasaki disease Kawasaki disease compared the number of circulating endothelial cells:complete set of Kawasaki disease in children with the number of CEC was (10.48±5.69)/0.9ul, incomplete Kawasaki disease group The number of children with CEC (7.43±4.08)/0.9ul, showed no significant difference (P> 0.05).
     Conclusion
     Acute phase of Kawasaki disease in children with significantly elevated levels of circulating endothelial cells, acute coronary artery injury group, the level of circulating endothelial cells than those without injury group, the level of detection of circulating endothelial cells contribute to early diagnosis of Kawasaki disease.
