Ｄ二聚体（Ｄｄｉｍｅｒ）是纤维蛋白单体经活化因子ⅩⅢ交联后，再经纤溶酶水解所产生的一种交联纤维蛋白特异性降解产物，其水平的增高反映继发性纤维活性增强，可作为体内高凝状态和纤溶亢进的分子标志物之一［１］。为了深入探讨各种肝病与继发性纤溶亢进的关系，我们 D  dimer (Ddimer) is a fibrin monomer by the activation factor Ⅹ Ⅲ cross-linked, and then hydrolyzed by plasmin a cross-linked fibrin-specific degradation products, the level of increase reflects the secondary Enhanced sexual fiber activity, can be used as one of the molecular markers of hypercoagulable state and fibrinolysis in vivo [1]. In order to further explore the relationship between various liver diseases and secondary fibrinolysis, we
