窒息新生儿血清胱蛋白酶抑制剂C检测及意义

目的探讨窒息新生儿血清胱蛋白酶抑制剂C（Cys C）水平在评价新生儿窒息后肾损害的意义。方法以68例窒息新生儿为研究对象,按Apgar评分分为轻度窒息组（47例）和重度窒息组（21例）;以40例健康足月新生儿作为对照组,在入院后抽取外周静脉血3mL,检测各组血清Cys C水平,并与血清尿素氮（BUN）、肌酐（Cr）等指标进行相关性分析。采用SPSS 10.0软件进行多因素方差分析和χ2检验比较其差异。结果在对照组、轻度窒息组和重度窒息组中,血清Cys C水平分别为（0.85±0.31）mg/L,（1.77±0.37）mg/L和（2.61±0.47）mg/L,血清BUN水平分别（4.61±1.16）mmol/L、（6.58±1.33）mmol/L和（8.73±2.67）mmol/L,血清Cr水平分别为（48.51±12.89）μmol/L,（49.93±14.62）μmol/L和（71.36±13.33）μmol/L,与对照组及轻度窒息组相比,重度窒息组血清BUN、Cr和Cys C水平显著升高,差异有显著性（P〈0.01）。三组之间对比Cys-C均有显著统计学意义,而BUN和Cr在对照组与轻度窒息组间差别无显著性。结论 Cys C是评价新生儿窒息后肾小球滤过功能损害的敏感指标。

The significance of serum cystatin C in newborn with asphyxia

Objective: To discuss the clinical significance of detecting serum cystatin C for estimating the deline of Glomerular induced by neonatal asphyxia.Methods: 68 cases of neonatal asphyxia were divided into mild asphyxia group(47 cases),severe asphyxia group(21 cases) according to Apgar score.40 cases of healthy full-term newborns were selected as a control group in the same period.The peripheral vein blood 3 ml was drawn out on all children in the third day after birth.the level of Cys C detected by immunotur...
