Abstract:Objective To study the level changes of tau protein, activin A, neuro-specific enolase (NSE) in premature infants with hypoxic ischemic encephalopathy, and to analyze its clinical significance. Methods The total of 131 cases of hypoxic ischemic encephalopathy treated in Xuzhou Children′s Hospital from February 2016 to December 2017 were selected as the study group, 100 cases of premature infants without hypoxic ischemic encephalopathy at the same period were selected as the control group. The serums tau protein, activin A and NSE levels of postnatal 7 d infants in two groups were compared. The preterm infants in the study group were divided into mild group (32 cases), moderate group (61 cases) and severe group (38 cases) according to the severity of the disease. The serum levels of tau protein, activin A, NSE and neonatal neurobehavioral (NBNA) score in postnatal 7 d infants with different severity was compared. The correlation between NBNA score, serum tau protein, activin A and NSE level was also analyzed. Results The levels of serum tau protein, activin A and NSE in preterm infants of the study group were significantly higher than those of the control group, the differences were statistically significant (all P < 0.01). Serum tau protein and activin A and NSE levels of mild group, moderate group and severe group showed a rising trend, the differences between groups were statistically significant (all P < 0.01). The NBNA score in the preterm 7 d infants of severe group was significantly lower than that of the moderate group and mild group, while the moderate group was significantly lower than that of the mild group, the differences between the groups were statistically significant (P < 0.05). Pearson correlation analysis showed that serum tau protein, activin A and NSE levels in premature infants with hypoxic ischemic encephalopathy were negatively correlated with NBNA scores (r = -0.612, -0.583, -0.648, all P < 0.05); the level of serum tau protein in premature infants with hypoxic ischemic encephalopathy was positively correlated with the levels of activin A and NSE (r = 0.531, 0.487, all P < 0.05); serum activin A was positively correlated with NSE level (r = 0.443, P < 0.05). Conclusion The serum tau protein, activin A and NSE of hypoxic-ischemic encephalopathy are highly expressed, and are closely related to the neural development of premature infants.
