Summary: This is a multicenter, randomized, double-blind, placebo-controlled Phase III clinical study designed to evaluate the efficacy of recombinant human tissue-type plasminogen activator variant (rhTNK-tPA) (0.25 mg/kg, maximum dose 25 mg) compared with placebo in patients with acute large vessel occlusive stroke who present within 4.5 to 24 hours of symptom onset. The study plans to enroll patients wi...

Summary: The goal of this clinical trial is to learn if a combination of antiplatelet drugs works better than intravenous tissue plasminogen activator to treat small ischemic stroke (lacunar stroke). The main questions it aims to answer are: Is a combination of antiplatelet drugs non-inferior to the current standard tissue plasminogen activator treatment? Does a combination of antiplatelet drugs reduce the...

Summary: Acute ischemic stroke is one of the main diseases leading to high risk of disability and morbidity worldwide. Since intravenous thrombolysis(IVT) can effectively improve the long-term functional prognosis of acute ischemic stroke(AIS), IVT within 4.5 hours of onset has been widely recommended by international guidelines. Although 35-53% of AIS patients achieve functional independence after receivi...

Summary: According to the Chinese Guidelines for the Diagnosis and Treatment of Ischemic Stroke, intravenous thrombolysis with urokinase, administered at doses of 1-1.5 million IU within 6 hours of symptom onset, has been shown to be both safe and effective for patients with acute ischemic stroke. Compared to alteplase, urokinase offers considerable cost advantages while maintaining comparable therapeutic ...

Summary: Heart attacks and strokes are among the most common causes of premature death in individuals living with spinal cord injury (SCI) and appear to occur earlier in life. The factors that lead to the heighten and accelerated risk of heart attacks and strokes in adults living with SCI remain poorly understood. The investigators aim to uncover why this happens and find ways to prevent it. Our research f...

Summary: Annexin A2 (ANXA2), an endothelial cell receptor for plasminogen and tissue plasminogen activator, plays a pivotal role in regulation of fibrinolysis in vitro and in vivo and has been identified as a new autoantigen in antiphospholipid syndrome (APS). ANXA2 can exist as a monomer or a heterotetrameric complex with S100A10 protein. The aim of this study was to evaluate the cell membrane expression ...

Summary: This study looks at whether stroke patients who take FXa inhibitors (a type of blood thinner) can safely receive clot-busting treatment (IVT). IVT is a common emergency treatment for stroke, but current guidelines say it should not be given to people who have taken FXa inhibitors in the last 48 hours. This is because doctors worry that IVT might cause dangerous bleeding in the brain. However, new ...

Summary: In 2015, five randomized trials showed efficacy of endovascular thrombectomy over standard medical care in patients with acute ischemic stroke caused by occlusion of arteries of the proximal anterior circulation. However, sufficient recanalization (mTICI2b-3) can 't be acquired in all patients under thrombectomy. There is a lack of evidence that whether salvage intra-arterial thrombolysis is benef...

Summary: The centre of the retina (macula) at the back of the eye contains cells that give us our central vision that we use for reading and recognising faces. These cells can be damaged by a disease called wet age-related macular degeneration (AMD), where new abnormal blood vessels grow through the macula and leak fluid. This can affect vision. In some cases, wet AMD can also cause a bleed under the macul...

Summary: A phase III, randomized, multi-center, investigational, open label clinical trial that will examine whether treatment with endovascular thrombectomy is superior to standard medical therapy alone in patients who suffer a Distal Medium Vessel Occlusion Ischemic Stroke within 12 hours from time last seen well

Summary: The recent validation of thrombectomy in addition to thrombolysis with intravenous administration of alteplase suggests a major revolution in the management of acute strokes. This treatment option also opens up a new field of research, making possible the analysis of the clot responsible for intracranial occlusion. Indeed, in about 30% of the cases, the thrombectomy procedure makes it possible to ...

Summary: Previous study showed that the proportions of hemorrhagic Infarction after intravenous thrombolysis were 24.2% and 32.5% in the control group and the alteplase group, and most of them were asymptomatic. Hemorrhagic Infarction was a part of the natural progression after acute ischemic stroke. Previous study have shown no significant relationship between hemorrhagic Infarction and poor outcome in ac...
