Résumé
Objective To explore the change of activin A(ACT A) in umbilical artery blood of newborns with fetal distress and its clinical significance.Methods Forty healthy pregnant women(control group)and 35 pregnant women with fetal distress (experimental group)were collected.The levels of ACT A of umbilical artery blood in both groups were determined by a solid quantitative biotin-avidin system enzyme-linked immunosorbent assay(BAS-ELISA),umbilical artery blood gas were also measured.Results The level of ACT A of umbilical artery blood in fetal distress group was (1 235.89?178.78)ng/L,and that in control group was (627.28?75.24)ng/L,and the level of ACT A of umbilical artery blood in fetal distress group was significantly higher than that in control group(P
Résumé
Objective To investigate the value of C- reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-?) in early diagnosis of neonatal sepsis. Methods Sixty- five newborns were divided into experiment group and control group, experiment group was also divided into sure group and doubtful group by blood culture We assessed the level of serum CRP, IL-6 and TNF-? in 24 hours and after 24 hours of clinical diagnosis of sepsis in experiment group, and examined the blood culture before antibiotic treatment Serum CRP, IL-6 and TNF-? were also examined in 3 to 6 days old. Results 1 The levels of serum CRP, IL-6 and TNF-? in experiment group were significantly higher than that in control group 2. The sensitivity of IL-6 and TNF-? were higher than CRP in 24 hours in experiment group. 3. After 24 hours, the sensitivity of CRP was elevated,and there was no statistical difference compared with the IL-6. Conclusion IL-6 and TNF-? are the credible marker in the early diagnosis of neonatal sepsis, and are more sensitive than the CRP, the IL-6 is the first sensitive marker.
