Diagnostic value of serum NSE, S100B protein and myocardial zymogram in premature infants with intrauterine infection / 中国基层医药

ABSTRACT

Objective@#To explore the diagnostic value of serum NSE, S100B protein and myocardial zymogram in premature infants with intrauterine infection.@*Methods@#From January 2016 to December 2017, 60 preterm infants with intrauterine infection in the Integrated Chinese and Western Medicine Hospital of Wenzhou were selected in the study.According to whether brain injury occurred, they were divided into brain injury group (28 cases) and non-brain injury group (32 cases). Serum NSE content was detected by chemiluminescence method, serum S100B protein level was detected by enzyme linked immunosorbent assay (ELISA), and serum CK and HBDH levels were detected by automatic biochemical analyzer.The serum levels of NSE, S100B, CK and HBDH were compared between the two groups, the combined diagnostic efficacy of NSE+ S100B protein+ CK+ HBDH was analyzed, the correlation of serum NSE, S100B protein, CK, HBDH with brain injury wasanalyzed.@*Results@#The levels of serum NSE [(2.43±0.54)μg/L] and S 100B [(14.36±3.21)ng/L] in the brain injury group were higher than those in the non-brain injury group [(0.97±0.27)μg/L and (8.10±1.87)ng/L] (t=13.498, 9.370, all P<0.05). The levels of serum CK [(437.64±54.12)U/L] and HBDH [(387.91±56.45)U/L] in the brain injury group were significantly higher than those in the non-brain injury group [(183.54±32.58)U/L and (174.3±26.63)U/L] (t=22.347, 19.126, all P<0.05). The sensitivity and specificity of the combined diagnosis of NSE+ S100B protein and myocardial zymogram were higher than those of each single index.Serum NSE, S100B protein, CK and HBDH were positively correlated with brain injury.@*Conclusion@#The elevation of serum NSE, S100B protein and myocardial zymogram in preterm infants with intrauterine infection after birth has certain clinical significance in judging whether brain injury occurs or not.
