摘要:目的:分析高膽紅素血癥新生兒血清神經(jīng)元特異性烯醇化酶(NSE)含量和新生兒行為神經(jīng)能力測(cè)評(píng)(Neonatal Behavioral Neurological Assessment,NBNA)的變化,探討高膽紅素血癥新生兒血清NSE含量變化的臨床意義。方法:應(yīng)用放射免疫分析法分別測(cè)定60例高膽紅素血癥新生兒和20例對(duì)照組新生兒血清NSE含量,同步測(cè)定血清總膽紅素(TSB),進(jìn)行NBNA評(píng)分;高膽紅素血癥組早期干預(yù)后再次測(cè)定血清NSE含量。結(jié)果: 與對(duì)照組比較,高膽紅素血癥新生兒血清TSB、NSE含量顯著升高,而NBNA評(píng)分明顯降低,差異有顯著性意義(Plt;0.01);對(duì)照組與高膽紅素血癥新生兒輕度增高、中度增高、重度增高四組兩兩比較(均Plt;0.05),存在顯著性差異;血清NSE含量與NBNA評(píng)分呈明顯負(fù)相關(guān)(r=-0628,Plt;0.01);高膽紅素血癥新生兒經(jīng)早期干預(yù)治療后,血清NSE含量均下降(Plt;0.05),差異有顯著性。結(jié)論: 高膽紅素血癥可導(dǎo)致新生兒腦損傷,血清NSE含量可以作為腦損傷的監(jiān)測(cè)指標(biāo)。Abstract: Objective: To analyze levels of neuronspecific 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 radioimmunoassay; Also total serum bilirubin (TSB) and NBNA were detected. In the hyperbilirubinemia group,serum NSE level were measured second when TSB were less than 855 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.
