【摘要】 目的探讨血胱抑素C（SCys C）、β₂微球蛋白（β2-MG）在检测早产儿早期肾功能损伤的诊断价值。方法按出生胎龄将研究对象分成2组,28³2周早产儿50例（A组）,33³7周早产儿50例（B组）;对照组为正常足月儿50例。测定3组患儿的SCys-C、β₂-MG、尿素氮、肌酐浓度及相关性分析。结果 SCy-C、β₂-MG在A组与B组比较、A组与对照组比较有差异（P<0.05）;SCys-C、β₂-MG之间有相关性（r=0.55）。结论 SCys-C、β₂-MG作为检测早产儿肾功能的指标,二者联合检测可为早产儿临床肾功能的检测提供更可靠的指标。更多还原

【Abstract】 Objective To discuss of diagnostic value for serum cystatin C（SCys C）,β₂ microglobulin（β₂-MG） in early renal injury in preterm neonates.Method According to gestational age were divided into two groups,and 28-32 weeks premature were 50 cases（group A）,33 to 37 weeks premature were 50 cases（group B）.Normal full term was 50 cases as control group.Determination of three groups of children SCys-C,beta 2-MG,concentration of urea nitrogen,creatinine,and correlation analysis.Result SCys-C,beta 2-MG in group A and group B in the comparison,A group also had differences compared with control group（P <0.05）.There is a correlation between SCys-C and beta 2-MG（r=0.55）.Conclusion SCys-C、β₂-MG were used as indicators to detect renal function of prematurity,and the joint detection can be premature clinical testing and can provide a more reliable indicator of renal function.更多还原
