title: [A preliminary study on the markers of pulmonary vascular endothelial cells in patients with ARDS].
abstract: OBJECTIVE
  To explore the changes of the markers of pulmonary vascular endothelial cell (PVEC) in patients with ARDS.
  
  
  METHODS
  The levels of plasma circulating endothelial cell(CEC), granule membrane protein-140(GMP-140), endothelin-1(ET-1) and von Willebrand factor (vWF) were determined respectively in 13cases of ARDS. The vWF on the surface of the PVEC were stained in 5 cases of ARDS.
  
  
  RESULTS
  Circulating CEC, GMP-140, ET-1 and vWF levels were increased significantly (P < 0.01) but scores of vWF expression on the PVEC became weak (P < 0.01) in ARDS samples. The level of plasma GMP-140 elevated dramatically in 2nd day( > 4 times).
  
  
  CONCLUSIONS
  PVEC are severely impaired during ARDS. GMP-140 released from PVEC might be a satisfactory criteria for early surveillance and for evaluation of prognosis of ARDS in clinical practice.
