ABSTRACT
Objective To investigate the effect of polymorphism of plasminogen activator inhibitor-1(PAI-1) promotor region gene,plasma tissue plasminogen activator(t-PA)and PAI-1 on patients with acute pulmonary thromboembolism(APTE).Method Fifty-two patients with APTE were divided into two groups according to the presence or absence of traditional enviromnent risk facters,and there were26 patients in each gnup,and auother 57 healthy indiriduals as controls were analyzed.The genotypos of subjects were determined for the 4G/5G polymorphism of PAI-1 gene using polymerase chain reaction based restriction fragment length polymorphism analysis.Plasma PAI-1 and tPA were measured by ELISA.Results(1)The ratio of 4G/4G genotype in group without traditional environment risk factors was much higher than that of the other two groups.(2)Plasma t-PA decreased and plasma PAI-1 elevated significantly in group without traditional environment risk factors compared with that of the other two groups.(3)Except the 5G homozygous,plasma PAI-1 level in group without traditional environgment risk factors was significantly higher than the other two groups.There existed correlation between 4G allele and plasma PAI-1.Conclusions 4G/5G polymorphism of PAI-1 gene is associated with AFFE.4G/4G genotype increases the risk of APTE for individuals without traditional risk factors.There are hypercoagulation and hypofibrinolysis in APTE patients without traditional risk factors.
