title: [Correlation of Thrombosis and Prothrombotic State with Coagulation Factor V Gene Polymorphism and APCR. HHcy].
abstract: OBJECTIVE
  To investigate the correlation of patients with thrombosis or prothrombotic status with hyperhomocysteinemia (HHcy), activated protein C-resistance(APCR) and gene polymorphism of coagulation factor V.
  
  
  METHODS
  Three hundred healthy voluteers were selected as controls, 223 cases of thrombosis (80 cases of cerebral infarction of CT, the MI of 82 cases of myocardial infarction, venous thrombosis of VTE 61 cases), 270 cases of patients with prothrombotic state (76 cases of pregnancy disease of PIH, 62 cases of chronic obstructive pulmonary disease (COPD), 60 cases of diabetes(DM) and 72 cases of cancer) were enrolled in this study. The plasma APCR and hyperhomocysteinemia were detected by APTT coagulation method and cycling enzyme method respectively, and restriction fragment length polymorphism(RFLP) were was used to detect the gene polymorphism of FV G1691-A, G1091-C and A1090-G in the patient and control groups.
  
  
  RESULTS
  APCR positive rate was 62.29% and 7.33%, and the positive hyperhomocysteinemia accounted for 68.42% and 10.00% respectively in the group of the patients with venous thrombosis and the normal control group. 3 cases of heterozygous FV gene mutations were found in the APCR-positive patients with venous thrombosis.
  
  
  CONCLUSIONS
  HHcy possitive rate of patients with venous thrombosis is signiticantly higher than that in control, the HHcy is one of the important causes resulting in thrombosis, the patients with venous thrombosis have proved to be with APCR, and the possitive APCR may be related with the coagulation factor V gene polymorphism.
