The utility of intravenous tissue plasminogen activator (IV t-PA) in improving the clinical outcomes after acute ischemic stroke has been well demonstrated in past clinical trials. Though multiple initial small series of endovascular stroke therapy had shown good outcomes as compared to IV t-PA, a similar beneficial effect had not been translated in multiple randomized clinical trials of endovascular stroke therapy. Over the same time, there have been parallel advances in imaging technology and better understanding and utility of the imaging in therapy of acute stroke. In this review, we will discuss the evolution of endovascular stroke therapy followed by a discussion of the key factors that have to be considered during endovascular stroke therapy and directions for future endovascular stroke trials.

We report removing a large subretinal hemorrhage by means of vitrectomy combined with the use of tissue plasminogen activator(tPA) to facilitate clot removal. A 25-year-old man had a 4 days history of visual loss in the right eye after blunt trauma. The right fundus had a large subretinal hemorrhage involving macula. Surgery was performed the following day. A small retinotomy was made, through which tPA was injected into the subretinal space and through which the dissolved clot was removed. The use of tPA minimizes surgical manipulation of the retina and greatly reduces the size of the retinotomy reguired for evacuation of subretinal bood. Although the long-term prognosis is guarded, this case does suggest that tPA may be a useful adjunct in managing of subretinal hemorrhage.

Thromboembolism is a crucial part of the global disease burden. It has high incidence, high mortality and disability rates, and the mechanism of occurrence and development is extremely complex. It is difficult to detect the disease in the early stage so that we have trouble with clinical prevention and treatment in general. At present, four items of blood coagulation and D-dimer have been widely used in the evaluation and auxiliary diagnosis of thromboembolism, the monitoring of effect for antithrombotic drugs and other fields. The thrombus biomarkers including thrombin-antithrombin complex (TAT), thrombomodulin (TM), tissue plasminogen activator-inhibitor complex (t-PAIC) and α2-plasmin inhibitor-plasmin complex (PIC) fill the gap of laboratory diagnosis before clinical symptoms appear in some degree. This article aims to explain the current application status of TAT, TM, t-PAIC and PIC in thromboembolism and explore their potential application value, so as to provide a reference for selecting appropriate early monitoring indicators for high-risk population of thromboembolism.

BACKGROUND: There are evidences that uPA and its inhibitor play a key role in tumor spread. We studied whether uPA and PAI-1 expressions could serve as prognostic parameters along with clinical, gross and microscopic findings in gallbladder carcinomas. METHODS: We analyzed 42 cases of gallbladder carcinomas by immunohistochemical staining and clinicopathologic parameters. RESULTS: uPA and PAI-1 were more frequently expressed in the adenocarcinoma than in the normal or benign gallbladder tissue. The uPA expression in the glands of low grade adenocarcinoma was significantly correlated with both distant and lymph node metastases. The uPA expression in the stroma around the low grade adenocarcinoma was significantly correlated with either distant or lymph node metastasis. The PAI-1 expression was significantly correlated with lymph node metastasis only for both distant and lymph node metastases. In multivariate analysis, the lymphatic invasion was significantly related to poor survival (p= 0.0115). In univariate analysis, the cases without lymphatic invasion had prolonged survival. Positive expression of uPA in the glands of low-grade adenocarcinoma was significantly correlated with poor survival (p=0.0391). CONCLUSION: In conjunction with clinicopathologic findings, expressions of uPA and PAI-1 may be useful prognostic markers in gallbladder carcinomas.
