| Outline of Final Research Achievements |
Neutrophils were isolated from septic patients and healthy volunteers and harvested for 4 hours. The apoptosis were assessed by Anexine V using flowcytometer, and the area of neutrophil extracellular traps (NETs) was assessed by immunofluorescence staining using anti-H1 antibody and anti-neutrophil elastase antibody. Neutrophils from healthy volunteers were stimulated by lipopolysaccharide. And the plasma cell-free DNA was assessed by realtime RT-PCR using human globin gene. Septic patients showed high cell-free DNA concentrations, low neutrophil apoptosis%, larger NETs areas. The apoptosis% of female was significantly lower than that of male in LPS-stimulated healthy volunteers’ neutrophils. NETs area of female tended to be higher than that of male in septic shock patients.
