title: [Expression of heat shock protein 72 in leukocytes from patients with acute trauma and its relationship with survival].
abstract: OBJECTIVE
  To determine the expression of heat shock protein 72 (HSP 72) in leukocytes of patients with acute trauma, and evaluate its relationship with survival.
  
  
  METHODS
  Thirty acute trauma patients with acute physiology and chronic health evaluation III (APACHE III) > or = 18 were included as study subjects. Blood samples were serially obtained at three time points: days 0-1, days 2-6 and days 7-14 after the trauma. Expression of HSP72 was assessed with immunohistochemistry, and the expression of HSP72 mRNA was assessed with semi-quantified reverse transcription-polymerase chain reaction (RT-PCR), and the relationship between their levels and the survival rate (survival period > 2 months) was analyzed.
  
  
  RESULTS
  The expression of HSP72 was significantly enhanced on post-trauma days 2-6. The levels of HSP72 in the survivor groups were higher than that in non-survivors.
  
  
  CONCLUSIONS
  The study suggests that acute trauma can lead to a marked elevation of HSP72, and its peak level appears on days 2-6, which might be correlated with 2-month survival of the afflicted patients.
