【摘要】 目的　研究胃癌患者凝血与纤溶系统的变化。方法　比较胃癌患者 (胃癌组 )与非肿瘤患者 (对照组 )的手术前、后 2周血小板聚集试验 (PAGT) ,凝血酶原时间 (PT) ,活化部分凝血活酶时间 (APTT) ,组织因子途径抑制物 (TFPI) ,D -二聚体 (D dimer) ,组织纤溶酶原激活物活性 (t PA :a)等指标。结果　胃癌组PAGT较对照组增强 (P <0 .0 5 ) ,PT和APTT明显缩短 (P <0 .0 5 ) ,TFPI降低(P <0 .0 5 ) ,D -二聚体和t PA :a显著升高 (均P <0 .0 1) ,发生淋巴结转移和低分化腺癌者尤为显著 (P <0 .0 5或P <0 .0 1)。手术切除肿瘤后各指标有不同程度的改善。结论　胃癌患者处于高凝和纤溶亢进状态 ,在淋巴结转移和肿瘤细胞分化差的患者中尤为明显。更多还原

【Abstract】 Objective To study the alternation of coagulation and fibrinolysis in patients with gastric cancer(GC) . Method Platelet aggregation test(PAGT), prothrombin time (PT), activated partial thromboplastin time(APTT), tissue factor pathway inhibitor(TFPI), D-dimer and tissue plasminogen activator(t-PA: a)were detected in 48 GC patients(GC group) at two weeks pre- and post-operation respectively;and compared with non-tumor patients(control group). Results Compared with control group, in GC group,especially in GC patients with lymphatic metastasis,the PAGT increased (P<0.05); PT and APTT shortened , and TFPI decreased(all P<0.05); D-dimer and t-PA: a elevated(all P<0.01) .Those alternations improved after resection of GC. Conclusions Hypercoagulation and fibrinolysis exist in patients with gastric cancer, especially in GC patients with metastasis and poorty differentiated cancer.更多还原
