title: [Detection of platelet Ca2+(i), CD62P, CD63 and plasma CD62P in cirrhosis patients].
abstract: OBJECTIVE
  To study on the relationship between platelet Ca2+(i), CD62P, CD63, serum CD62P (SCD62P) and cirrhosis patients.
  
  
  METHODS
  Platelet CD62P, CD63 were determined with flow cytometry, SCD63P with ELISA, and Ca2+(i) in platelet was determined with fluorophotometry.
  
  
  RESULTS
  Platelet Ca2+(i), CD62P, CD63, and SCD62P levels in cirrhosis patients were (103.1+/-22.2)nmol/L, (47.6+/-20.0)%, (47.1+/-24.6)%, and (67.6+/-37.6)microg/L, and in controls were (57.6+/-13.1)nmol/L, (3.1+/-0.7)%, (2.5+/-0.7)%, and (24.0+/-6.5)microg/L, respectively. The levels in the former were higher than those in the latter (t > or = 6.148, P<0.05). The above levels in upper gastrointestinal haemorrhage group were much higher than those in the non-haemorrhage group (120.3nmol/L+/-18.8nmol/L vs 91.1nmol/L+/-14.3nmol/L, 64.9%+/-14.7% vs 34.6%+/- 11.9%, 70.9%+/-14.5% vs 30.2%+/-14.4%, and 103.6microg/L+/-14.9microg/L vs 40.8microg/L+/-24.0microg/L, respectively, t > or = 5.380, P<0.05). But the numbers of platelet between the two groups were no obvious difference.
  
  
  CONCLUSIONS
  Platelet in the cirrhosis patients is greatly active, and the detection of platelet CD62P, CD63, SCD62P has a certain value in judging the degree of cirrhosis.
