title: [Clinical significance of serum S-100B protein in severe cerebral injury].
abstract: OBJECTIVE
  To investigate the value of S-100B protein as a biology marker in diagnosis and prognostic after severe cerebral injury.
  
  
  METHODS
  Sixty-six patients with severe head injury (Glasgow coma scale score (GCS)<or=8) were included in this study, venous blood samples for S-100B protein were obtained as soon as possible after admission and every 24 hours thereafter for a maximum of 3-7 consecutive days. Serum levels of S-100B protein were compared with outcome (Glasgow outcome scale score, GOS) after 6 months.
  
  
  RESULTS
  Of 66 patients, 25 patients died, mutilation in 22 patients, 19 patients had a good outcome. Patients who died had significantly higher serum S-100B values compared with those who survived (median 2.60 microg/L vs. 0.55 microg/L, P<0.001), 14 of 25 patients who died had peak S-100B values of 2.00 microg/L or higher, compared with 4 of 41 surviving patients (P<0.005).
  
  
  CONCLUSIONS
  S-100B protein has a reliable value in diagnosis and prognostic after severe head injury.
