Objective:To investigate the changes and significances of serum cystatin C and transforming growth factor-β1 levels for the neonatal asphyxia.Methods:Forty-six asphyxia newborns were chosen as the asphyxia group,and thirty healthy newborns were selected as the control group.The TGF-β1,CysC,BUN,Scr,and GFR levels of both groups were detected on the 1st,3rd,7th day after hospitalization.According to the renal injury,the 46 newborns were divided into normal group and asphyxia group,and the serum indexes were detected and analyzed.Results:On the 1st,3rd,7th day after hospitalization,the TGF-β1,GFR of asphyxia group was obviously increased and was lower than those of the control group (P＜0.05);the level of CysC,BUN,Scr in both groups were decreased,and the change degree in asphyxia group were higher than that of the control group (P＜0.05);the CysC,BUN,Scr in renal injured group were higher than those of normal group,and TGF-β1,GFR were much lower (P＜0.05).Additionally,TGF-β1 level of renal injured group was negatively correlated to the BUN and Scr,and positively correlated with the GFR (P＜0.05).The level of serum CysC in renal injured group was positively correlated to BUN and Scr and negatively correlated to GFR (P＜0.05).Conclusion:The serum TGF-β1,CysC in asphyxia newborns had significant changes compared with the healthy newborns and was correlated to the renal injured indexes,which had clinical directive significance on the early diagnosis,condition judgment,and prognosis of neonatal asphyxia with renal injury.
