摘　　要：目的探讨血清心肌型脂肪酸结合蛋白(H-FABP)定量测定对新生儿缺氧缺血性脑病(H IE)患儿合并心肌损害的临床应用价值。方法H IE组新生儿35例,正常对照组新生儿15例。正常对照组于生后1天,H IE组分别于生后1天(急性期)及第7天(恢复期)抽股静脉血4 m l,检测H-FABP和心肌型肌酸激酶同工酶(CK-MB)水平。结果急性期H IE组血清H-FABP和CK-MB水平均明显高于正常对照组(P<0.01);恢复期轻、中度H IE患儿血清H-FABP和CK-MB水平均明显下降,与正常对照组差异无显著性(P>0.05),重度H IE患儿血清CK-MB水平与正常对照组比较差异也无显著性(P>0.05),而重度H IE患儿血清H-FABP水平明显高于正常对照组(P<0.01)。且血清H-FABP的浓度可随H IE的病情程度而相应变化。急性期H IE患儿血清H-FABP与CK-MB的阳性率分别为:H-FABP 94.3%,CK-MB 42.9%,差异有显著性(P<0.01)。急性期H IE患儿检测血清H-FABP的敏感性高于血清CK-MB。结论H-FABP是一种微小心肌损害高敏感的指标,对筛查H IE患儿有无合并心肌损害、指导治疗及判断H IE的病情严重程度及预后具有重要的应用价值。Objective To explore the clinical value of the hearttype fatty acid binding protein （H -FABP）in neonatal hypoxic- ischemic encephalopathy（HIE）. Methods Peripheral venous blood samples （4 ml each） were obtained from 35 neonates with HIE （HIE group） 1 day （acute period） and 7 days （recovery period） after birth, and from 15 normal neonates （ normal control） 1 day after birth. Serum H - FABP and myocardial - specific isoenzyme of creatine kinase （ CK - MB） levels were measured. Results During the acute period in HIE group, the levels of serum H - FABP and CK - MB were significantly higher than that in the normal control （ P 〈 0.01 ）. In recovery period, serum H - FABP and CK - MB dropped to normal level in slight/mid HIE neonates compared to normal control （ P 〉 0.05 ） ; CK - MB also dropped to normal level in severe HIE neonates compared to normal control （ P 〉 0.05 ） ; but in the severe HIE neonates the level of serum H - FABP was significantly higher than that of the normal control （ P 〈 0.01 ）. In addition, the levels of serum H - FABP varied with the severity of HIE. In acute period, the positive rates of H - FABP and CK - MB were 94.3% and 42.9% respectively, with the sensitivity of serum H - FABP being higher than that of serum CK - MB （ P 〈 0.01 ）. Conclusion H - FABP is a sensitive index of mini myocardial damage. It can be used as a test for screening myocardial damage in HIE neonates, guiding the treatment of HIE and evaluating its severity and prognosis.
