Thrombolytics (eg, tissue-type plasminogen activator ) cannot be used prophylactically in this high-risk setting because of their short duration of action and risk of causing hemorrhage and central nervous system damage.

溶栓（例如，组织型纤溶酶原激活）不能用于prophylactically在这高风险的设定，因为它们的短期行动，并可能造成出血和中枢神经系统的损害。

Objective The aim of the study, rt-PA/urokinase comparison in China, was to evaluate the safety and efficacy with treatment by recombinant tissue-type plasminogen activator 50 mg compared with conventional dose of urokinase among Chinese patients with acute myocardial infarction.

目的 评价重组组织型纤溶酶原激活剂50mg对国人急性心肌梗塞溶栓治疗的疗效及安全性，并与国产尿激酶常用剂量的疗效进行对比。

To combine the fibrinolytic with anticoagulant activities for therapy of thrombotic deseases, a fusion protein made of tissue-type plasminogen activator and hirudin was constructed and expressed in Pichia pastoris.

构建并表达兼有溶栓和抗凝活性、减少出血副作用的人组织型纤溶酶原激活剂和水蛭素(HV2)的融合蛋白。

The minute I was far enough above the town to see I could make the towhead, I begun to look sharp for a boat to borrow, and the first time the lightning showed me one that wasn't chained I snatched it and shoved.

我走到了离镇子相当远的地方，能看清到沙洲的路了，我就仔细寻找，看能不能借到一只小船。电光一闪，我就见到有一只没有栓住的小船。我一跳上去，就划将起来。

132 patients with PICH between June 1999 and June 2001 in the Tongji Hospital were included in the present study. Patients with hemorrhage secondary to traumatism, brain tumor, thrombolytic treatment, vascular malformation or with hemorrhagic infarction were excluded.

通过病史、神经系统体格检查和头部CT检查，并排除外伤性脑出血以及脑肿瘤、动静脉畸形、出血性脑梗塞、溶栓治疗等引起的继发性脑出血后，将1999年6月至2001年6月武汉同济医院住院的132例脑出血患者作为研究对象。

We present 2 case reports of which the residual bone height is 1~3mm in either case. After marking and drilling the alveolar ridge with trephine bur, the bone plug was intruded with gentle force using bone condensers.

本文提出二个病例，在可利用剩余骨高度1~3mm的情况下，第一阶段先用外径6.lmm，内径5.25mm之骨环锯将塉骨作记号并钻开，再以推骨器轻敲慢慢将此骨栓往上推。

Gallica were exposed under ultra-violet ray and the mutants were screened in RBBR-containing PDA plates, and then the laccase activities of the mutated strains were determined by ABTS.

以粗毛栓菌T.gallica为出发菌株，通过紫外诱变处理其担孢子、PDA-RB亮蓝平板变色法初筛、ABTS法测定培养液漆酶活力复筛，获得1株漆酶高产诱变菌株SAH-12。
