RESUMO
Objective To investigate the significance of fibroblast growth factor 23 in metabolic bone disease of prematuriy.Methods 60 patients who had been treated in our hospital from March 2016 to March 2017 were included in this study.Blood biochemistry was examined two weeks after birth,and values of blood phosphorus, serum calcium and alkaline phosphatase were recorded. Serum levels of 25 hydroxyvitamin D3,parathyroid hormone and fibroblast growth factor 23 were detected two weeks after birth. 20 premature infants with metabolic bone disease were selected as a study group. 40 infants without metabolic bone disease were treated as a control group. Two weeks after treatment,the above indicators were measured and compared in the study group. Results Serum levels of 25 hydroxyvitamin D3,parathyroid hormone and fibroblast growth factor 23 were compared between the two groups 2 weeks after birth,the difference was statistically significant(P<0.05).Levels of serum parathyroid hormone and fibroblast growth factor 23 in the study group were not statistically significant after treat-ment(P > 0.05). Levels of 25 hydroxy vitamin D3 in the study group had statistically significant after treatment (P<0.05).Conclusions Early detection of fibroblast growth factor 23 can reflect metabolic bone disease in pre-term infants.It suggests that vitamin D should be adequately supplemented in early.
RESUMO
Objective To investigate the role of mylin basic protein,S100B and arterial blood gas analysis's levels in early diagnosis of brain injury in premature infant.Methods A total of 95 premature infants treated in our hospital were enrolled in the study.Experimental group was 45 premature infants with brain injury.Control group was 50 premature infants without brain injury were the.All patients were detected with arterial blood gas analysis,MBP and S100B on the 1st day and 7th day after birth.Results The pH,PCO2,BE,lactic acid,MBP and S100B's levels in experimental group were significantly different between the 1st day and 7th day after birth.In the 1st day after birth,compared with the control group,the pH,PCO2,BE,lactic acid,MBP and S100B in the experimental group were obviously high than that of control group.Conclusion On the 1st day after birth,monitoring arterial blood gas analysis,S100B protein and MBP's levels could be useful in early diagnosis of brain injury in preterm infants.
RESUMO
Objective To investigate the early diagnosis value of arterial blood gas analysis , neuron specific enolase and serum glial fibrillary acidic protein in brain injury of premature infant. Methods In the study, 95 premature infants admitted in our hospital were enrolled. 45 premature infants with brain injury were selected as experimental group. 50 premature infants without brain injury were selected as control group. All patients received arterial blood gas analysis , NSE and GFAP on the 1st day and 7th day after birth. Results There is statistically significant difference between the experimental group and the control group on the 1st day after birth in terms of pCO2, pH, BE and lactic acid (P<0.05). In experimental group, there is statistically significant difference between the 1st day and 7th day after birth in terms of pCO2, pH, BE and lactic acid (P < 0.05). The NSE and GFAP levels had statistically significant difference between the experimental group and the control group on the 1st day and 7th day after birth(P < 0.01); the NSE levels of experimental group had statistically significant difference between the 1st day and 7th day after birth (P < 0.05); The GFAP levels of experimental group had statistically significant difference between the 1st day and 7th day after birth (P < 0.01). Conclusion pCO2, NSE and GFAP levels are correlated with brain damage in premature infants in early stage. This could provide evidence of early diagnosis for brain injury in preterm infants.
