摘要
目的 探讨血清神经元特异性烯醇化酶(NSE)在窒息新生儿中的动态变化及其与脑损伤的关系.方法 收集2005年1月至2012年12月住院治疗的足月窒息新生儿75例(窒息组)和健康足月新生儿30例(对照组),采用酶联免疫吸附试验法检测两组新生儿出生后1,3,7d时血清NSE浓度变化,并分析其变化与窒息后脑损伤的关系.结果 出生后1,3,7d,窒息组轻度窒息新生儿和重度窒息新生儿血清NSE浓度均明显高于对照组[(29.85±8.53)、(59.26±15.75) μg/L比(15.59±6.25) μg/L,(23.69±6.54)、(47.28±12.46) μg/L比(15.38±5.84) μg/L,(18.95±5.37)、(62.57±19.62) μg/L比(13.92±5.37)μg/L],重度窒息新生儿明显高于轻度窒息新生儿,差异有统计学意义(P<0.05).出生后1,3,7d,脑损伤新生儿25例血清NSE浓度逐渐升高,而CT正常新生儿50例血清NSE浓度逐渐下降,脑损伤新生儿血清NSE浓度均明显高于CT正常新生儿[(37.48±12.09) μg/L比(30.95±11.86) μg/L、(51.84±14.21)μg/L比(21.73±6.15) μg/L、(68.25±18.69)μg/L比(15.62±5.94)μg/L],差异有统计学意义(P<0.05).结论 监测血清NSE浓度动态变化有助于早期辅助判断窒息新生儿脑损伤.
Objective To study the relation of the variations of serum neuron-specific enolase (NSE) level and brain damage in asphyxia neonatorum.Methods The serum NSE level were detected in 75 asphyxia neonatorum(asphyxia group) and 20 normal neonatorum(control group) by the method of ELISA after parturition 1,3 and 7 d.The relation of serum NSE level and brain damage was analyzed.Results After parturition 1,3 and 7 d,the serum NSE level in mild asphyxia group and severe asphyxia group was higher than that in control group [(29.85 ±8.53),(59.26 ± 15.75) μg/L vs.(15.59 ±6.25) μg/L; (23.69 ± 6.54),(47.28 ±12.46) μg/L vs.(15.38 ±5.84) μg/L; (18.95 ±5.37),(62.57 ±19.62) μg/L vs.(13.92 ±5.37) μg/L],and the serum NSE level in sever asphyxia group was higher than that in mild asphyxia group,there had significantly difference (P< 0.05).After parturition 1,3 and 7 d,the serum NSE level in brain damage neonatorum (25 cases) was increased and in CT normal neonatorum (50 cases) was decreased,the serum NSE level in brain damage neonatorum was higher than that in CT normal neonatorum [(37.48 ± 12.09) μg/L vs.(30.95 ± 11.86) μg/L,(51.84 ± 14.21) μg/L vs.(21.73 ±6.15) μg/L,(68.25 ± 18.69) μ g/L vs.(15.62 ± 5.94) μ g/L],there had significantly difference (P < 0.05).Conclusion The variations of serum NSE level can be the important indicator to monitor brain damage in asphyxia neonatorum.
