【摘要】 目的检测缺氧缺血性脑病(HIE)新生儿血清C3、C4的变化,了解HIE对非特异免疫功能的影响。方法HIE新生儿67例,根据生后的年龄和病情轻重分为1~3 d组32例,其中轻度HIE 14例,中重度HIE 18例。4~6 d组35例,其中轻度HIE16例,中重度HIE 19例。对照组30例为同期在我院产科出生的正常新生儿。采用散射比浊法检测血清C3、C4,结果进行统计学分析。结果1~3 d组血清C3、C4在轻、中重度HIE组与对照组比较均差异显著(P<0.05,0.01)。4~6 d组血清C3、C4在轻、中重度HIE组与对照组比较差异显著(P均<0.01)。1~3 d组和4~6 d组血清C3、C4轻度与中重度组比较均无显著差异(P均>0.05)。结论HIE可使患儿补体水平降低,合成补体的功能降低,但与HIE的程度无关。更多还原

【Abstract】 Objective To detect the changes of serum complement 3（C₃） and C₄ in neonates with hypoxic-ischemic encephalopathy（HIE） and its effects on non-specific immunological function.Methods Sixty-seven neonates with HIE and 30 normal full-term infants were recruited in the study.According to characteristic of immunological function and severity of HIE,the neonates were divided into 1-3 day group（n=32）and 4-6 day group（n=35）.In each group,it was divided into mild group and moderate-severe group.The complement in serum was detected by radial immunodiffusion assay with Behring Nephelometer 100 Analyzer.Results In 1-3 day group,levels of C₃,C₄ in serum were lower than those in control group（P<0.05,0.01）.In 4-6 day group,levels of C₃,C₄ in serum of HIE group were lower than those in control group（all P<0.01）.Conclusions The levels of C₃,C₄ in serum of HIE decrease.It will damage the immunological function,and severity of HIE does not contribute to change of complements.更多还原
