Objective:To analyze the effect of application of mouse nerve growth factor in neonatal period on brain development in premature infants.Methods:A total of 37 cases of premature infants given birth in our hospital from 1st January, 2015 to 30th December, 2015 were selected as research subjects and divided into observation group (n=18) and control group (n=19) according to different ways of intervention. Control group didn’t receive exogenous drugs, observation group received mouse nerve growth factor (NGF) treatment in neonatal period, and then differences in results of brain magnetic resonance imaging, electroencephalogram, brainstem auditory evoked potential, scores of Gesell developmental scale, levels of NSE, S-100β, 8-OHdG and 8-I-PGF2α and levels of TLR-4, TNF-α, IL-18 and so on of two groups after intervention were compared.Results:Proportions of normal MRI, EEG and BAEP of observation group were higher than those of control group, and proportions of severely abnormal were significantly lower than those of control group; scores of Gesell developmental scale motor, adaptive behavior, language and social skills of observation group in 3 months and 6 months of corrected gestational age were higher than those of control group; serum NSE, S-100β, 8-OHdG and 8-I-PGF2α levels of observation group after 3 months and 6 months of corrected gestational age were lower than those of control group ; serum TLR-4, TNF-α, IL-18, NF-κB and MMP-9 levels of observation group after 6 months of corrected gestational age were lower than those of control group, and levels of EGF and SOD were higher than those of control group.Conclusion: Application of mouse nerve growth factor in neonatal period of premature infants helps to promote nerve cell growth and development and optimize brain function of premature infants, and it has active clinical significance.
