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.

Objective To study the curative effect of prostaglandin E1(PGE1)on maintaining Sa(O2) and life span in the neonates with complete transposition of the large arteries(TGA).Methods Eleven of 19 neonates complete TGA received continuous PGE1 with the dosage of 5-20 ng/(kg?min),while the other 8 cases were set as control.The body temperature,Sa(O2),heart rate and blood pressure of both groups were recorded during the trial.Results The average Sa(O2) in trial group was (82.3?3.56)%,which had significant difference compared with the control group(t=8.232 P=0.001).The life span in trial group was much longer than control group.The body temperature,heart rate and blood pressure of trial group had no significant fluctuations.Conclusion PGE1 has an compkete effect on maintaining the ope-ning of patent ductus arteriosus (PDA) in TGA patients,which can improve the Sa(O2) and prolong the life span.
