METHODS: Plasma levels of TF and its inhibitor (TFPI), as well as u-PA and its receptor (u-PAR) were measured using ELISA in 76 patients with malignant tumors and 24 patients with benign tumors. RESULTS: Plasma levels of TF and u-PAR in the malignant tumor group were significantly higher than those of the benign tumor group and the normal control. U-PA and u-PAR increased significantly in patients with esophageal and gastric cancer. However, most of these parameters except TFPI did not vary according to pathological classification. A significant elevation was evident in patients with local infiltration, lymph node involvement and distal metastasis, while u-PAR only increased in the latter two categories. CONCLUSIONS: Both the TF and u-PA systems are activated in cancer patients. U-PA and its receptor might prove to be a clinically useful marker for disease progression.展开更多

The patency rate of the infarct-related artery (IRA) in patients in the thrombolysis group was significantly lower than that of patients in the primary stenting group (P<0.001). Recurrent myocardial infarction, and selective coronary stenting of patients with thrombolytic therapy were higher than that of patients in the primary stenting group (7.6% vs 1.5%, P<0.05; 20.6% vs 0, P<0.001, respectively). Left ventricular ejection fraction (LVEF) in patients in the thrombolysis group was lower than that of the stent group (55.6%±13.4% vs 65.8%±9.2%, P<0.001). Total hospitalization time of the thrombolysis group was longer than that of the stent group (16±7 d vs 11±4 d, P<0.001). Mortality in the thrombolysis group was higher than that of the stent group, but this difference was not significant (6.1% vs 3.1%, P>0.05).Conclusion Comparing with low dose rt-PA thrombolytic therapy after acute myocardial infarction, primary coronary stenting has a higher patency rate of the IRA, better cardiac function and shorter hospitalization time.展开更多
