缺氧缺血性脑病新生儿脑型肌酸激酶同工酶、胱抑素C的变化及其临床意义

目的探讨HIE新生儿血清脑型肌酸激酶同工酶（CK—BB）、胱抑素C（CysC）的变化。方法对56例HIE患儿（轻、中、重度分别为18、19、19例）及42例正常新生儿用日本O（ympus AU 1000全自动生化分析仪测定其血清CK—BB、CysC。结果1．中度HIE患儿血清CK—BB与对照组比较明显增高（P〈0．05），重度与轻度组比较明显增高（P〈0．05），重度组与对照组比较显著增高（P〈0．01）；各组HIE患儿CySC与对照组比较明显增高（P均〈0．01），中重度HIE患儿与轻度组比较血清CysC均显著升高（P均〈0．01）。2．新生儿血清CK—BB与CysC呈高度正相关（r=0．85P〈0．01）。结论联合检测血清CK—BB、CysC水平，可尽早发现HIE患儿的脑、肾损害。

Changes of Serum Brain Type Creatine Kinase Isoenzyme and Cystatin C in Neonates with Hypoxic-Ischemic Encephalopathy and Their Clinical Significance

Objective To explore the changs of serum brain type creatine kinase isoenzyme(CK-BB),cystatin C of newborns with hypoxic-ischemic encephalopathy(HIE) and assess their applications.Methods The serum concentrations of CK-BB and cystatin C were measured by turbidimertric immunoassay in 56 HIE newborns and 42 normal neonates.Results 1.Compared with controls,the concentration of serum CK-BB in moderate HIE newborns had significant differences(P<0.05);The same result lived in mild and severe HIE newborns(P<(0.05));Compared with controls,the concentration of serum cystatin C in HIE newborns had significant differences(P<(0.01));Compared with mild HIE newborns,the concentration of serum cystatin C in moderate-severe HIE newborns had significant differences(P<(0.01));2.The relevant coefficient of CK-BB and serum cystatin C of newborns were obviously significant(r=0.85(P<0.01)).Conclusion Serum CK-BB and cystatin C may be useful for assessment of brain and renal injury of children with HIE.
