摘要: 目的 探讨静脉血栓形成患者凝血因子Ⅻ(FⅫ)基因多态性对凝血和纤溶功能的影响。方法 分别采用一期凝固法、免疫比浊法及发色底物法检测75例静脉血栓形成患者及60名正常对照者的血浆凝血因子Ⅻ活性(FⅫ∶C)、纤维蛋白原(FIB)、D-二聚体(D-D)、凝血因子Ⅷ活性(FⅧ∶C)、血管性血友病因子(VWF)、纤溶酶原活性(PLG ∶A)、抗凝血酶活性(AT∶A)、蛋白C活性(PC∶A)等指标。采用直接测序法测定上述研究对象的FⅫ基因启动区第46位碱基多态性。结果 静脉血栓形成患者的46TT多态性较正常对照组比例增高,46TT型患者FⅫ∶C明显低于46CT、46CC型及正常对照组(P均<0.05);与正常对照组比较,46TT型的AT∶A活性明显减低,而FIB、D-D、FⅧ∶C和VWF含量明显升高(P均<0.05);但静脉血栓形成患者FⅫ多态性各型之间的上述指标差异无统计学意义(P>0.05)。FⅫ多态性各型患者及对照组之间的PLG和PC活性差异亦无统计学意义(P均>0.05)。结论 静脉血栓形成患者FⅫ基因46TT多态性明显增多而导致FⅫ活性明显下降;FⅫ基因多态性各组之间凝血和纤溶功能差异无统计学意义。

Abstract: Objective To investigate the influence of factor Ⅻ(FⅫ) polymorphism on the coagulation and fibrinolysis in patients with venous thrombosis. Methods The activity of plasma factor Ⅻ(FⅫ∶C), fibrinogen(FIB), D-dimer(D-D), factor Ⅷ(FⅧ∶C), von Willabrand factor(VWF), the activity of plasminogen(PLG∶A), the activity of plasma antithrombin(AT∶A) and the activity of protein C(PC∶A)were measured by onestage recalcification clotting time assay, immunoturbidimetry assay and chromogenic substrate method in 75 patients with venous thrombosis and 60 healthy controls. The 46th basyl polymorphism at promoter regions in FⅫ gene was analyzed by direct sequencing. Results The rate of 46TT polymorphism in patients with venous thrombosis was higher than that in control group, and the FⅫ∶C of the 46TT patients was obviously lower than those of the 46CT and 46CC patients and control group(P<0.05). In 46TT group, AT∶A was lower than that in control group,but the FIB, D-D, FⅧ∶C and VWF were higher(P<0.05). There were no significant differences in above parameters among the various FⅫ polymorphism groups with venous thrombosis(P>0.05), and there were also no differences in PLG∶A and PC∶A among these groups(P>0.05). Conclusions The FⅫ gene 46TT polymorphism is obviously increased in patients with venous thrombosis, and it will cause the decreasing of FⅫ. There are no statistical significances in the parameters of the coagulation and fibrinolysis at each FⅫ polymorphism group with venous thrombosis.
