摘要:目的:分析高胆红素血症新生儿血清神经元特异性烯醇化酶(NSE)含量和新生儿行为神经能力测评(Neonatal Behavioral Neurological Assessment,NBNA)的变化,探讨高胆红素血症新生儿血清NSE含量变化的临床意义。方法:应用放射免疫分析法分别测定60例高胆红素血症新生儿和20例对照组新生儿血清NSE含量,同步测定血清总胆红素(TSB),进行NBNA评分;高胆红素血症组早期干预后再次测定血清NSE含量。结果: 与对照组比较,高胆红素血症新生儿血清TSB、NSE含量显著升高,而NBNA评分明显降低,差异有显著性意义(P lt;0.01);对照组与高胆红素血症新生儿轻度增高、中度增高、重度增高四组两两比较(均P lt;0.05),存在显著性差异;血清NSE含量与NBNA评分呈明显负相关(r=-0628,P lt;0.01);高胆红素血症新生儿经早期干预治疗后,血清NSE含量均下降(P lt;0.05),差异有显著性。结论: 高胆红素血症可导致新生儿脑损伤,血清NSE含量可以作为脑损伤的监测指标。
Abstract: Objective: To analyze levels of neuronspecific enolase(NSE)in serum and neonatal behavioral neurological assessment (NBNA), to study whether NSE in serum can be used as a tool for the early identification of brain damage in neonatal hyperbilirubinemia. Methods: Serum NSE level of 60 full term infants with hyperbilirubinemia and 20 cases as to control group were measured by radioimmunoassay; Also total serum bilirubin (TSB) and NBNA were detected. In the hyperbilirubinemia group,serum NSE level were measured second when TSB were less than 855 μmol/L(5 mg/dL). Results: Compared with control group,the levels of serum TSB、NSE of the hyperbilirubinemia group were significantly higher, but NBNA score was significantly lower. The levels of serum NSE was significantly negative related to NBNA score. In the hyperbilirubinemia group, serum NSE level were significantly lower after treatment. Conclusion: Hyperbilirubinemia in neonates can cause brain damage. Serum NSE level could work as monitoring indexes of this damage.
