糖原磷酸化酶同工酶脑型和缺血修饰蛋白在新生儿窒息合并心肌损伤中的变化及临床意义

目的通过检测窒息新生儿血清中的缺血修饰蛋白(IMA)、糖原磷酸化酶同工酶脑型(GPBB)水平,探讨窒息患儿心肌损伤诊断中早期生物标志物的变化及临床意义。方法选取该院新生儿病房收治的166例新生儿作为研究对象,其中符合心肌损伤的136例,对照组30例。研究对象按窒息程度分为轻度窒息组和重度窒息组。所有患儿均于入院后1h后抽血进行GPBB和IMA的检测。结果非心肌损伤组、轻度窒息组GPBB水平高于对照组,差异有统计学意义(P0.05)。GPBB诊断窒息患儿心肌损伤的灵敏度高于IMA,差异有统计学意义(P0.05)。结论合并心肌损伤的窒息新生儿窒息程度与血清中IMA、GPBB水平密切相关,窒息合并心肌损伤患儿临床诊断指标灵敏度方面,GPBB指标优于IMA。

The level of glycogen phosphorylase isoenzyme BB and ischemia modified albumin in newborn with asphyxia and myocardial injury and its clinical significance

Objective To explore the clinical significance of early biomarkers in neonatal asphyxia diagnosis with myocardial damage by detection of ischemia modified albumin in neonatal serum(IMA) and glycogen phosphorylase isoenzyme BB(GPBB) for screening sensitive markers with direct myocardial injury.Methods 166 neonates were selected in our hospital as the research object,in which 136 cases with myocardial injury dividend into the experimental group and 30 cases into the control group.The experimental group were divided into mild group and severe group according to the degree of asphyxia.All the children were tested for GPBB and IMA 1 h after admission.Results The levels of GPBB in neonatal asphyxia myocardial injury group and severe asphyxia group were significantly higher than those in the control group,the difference was statistically significant(P<0.05).The sensitivity of GPBB in diagnosis of asphyxia was higher than that of IMA,the difference was statistically significant(P<0.05).Conclusion The degree of asphyxia is closely related to serum IMA,GPBB level in neonatal asphyxia complicated with myocardial injury.The sensitivity and specificity of GPBB in diagnosis asphyxia is better than IMA in children complicated with myocardial damage.
