The purpose of this study is to evaluate the diagnostic value of serum NT - proBNP in stroke associated with nonvalvular atrial fibrilltion.
- Clinical trial; Ischemic stroke; Bu-Yang-Huan-Wu Tang （BYHWT）; Gait parameter; Quality of life Stroke is the third of ten causing death disease constantly, and it also is third of consuming healthy insurance budget. There is 17,000 peoples disable due to stroke every year in Taiwan. Although ischemic stroke patient may use t-PA intravenously treatment within 3 hrs after stroke onset in modern medicine, and no others method may effect to treat ischemic stroke patients, thus, the study about stroke is an important issue. Bu-Yang- Huan-Wu Tang (BYHWT) has been became a main stream for the treatment of stroke after Qing dynasty Wang Qing-Ren theory that is BYHWT may treat stroke due to pattern of qi stagnation and blood stasis in traditional Chinese medicine. A number of researches report that BYHWT can reduce blood viscosity, anti-inflammation, enhancing neuronal regeneration and angiogenesis, but above-mentioned about BYHWT limit in the level of animal study and the scientific evidence is insufficiency in human trial. Therefore, the purpose of the present study was to investigate the therapeutic effect of BYHWT treating ischemic stroke by using a strict clinical trial. - We designed a randomized, double blind, placebo-controlled study to assess the therapeutic effect of BYHWT treating ischemic stroke. The study expects to finish the assessment of 120 patients with ischemic stroke in three years. The study divided into: 1) control group, receive placebo-BYHWT 3.0 g TID every day for continuously 6 weeks except ordinary medical care; 2) treatment group, the method is identical control group, but receive BYHWY. The main outcome was according to the changes of gait parameter including Speed, Cadence, Strike length, Gait cycle and Double support; and secondary outcome including the changes of Functional independence measurement scores and Barthel index scores, Ten Meters Walk Test, Short Physical Performance Batter, Berg Balance Test and WHO quality of life-brief (Taiwan Brief). - We predict the results of the present can provide scientific evidence to proof BYHWT can improve neurological deficit and also can improve quality of life in patients with ischemic stroke.
Ischemic stroke is a kind of common disease with great harm. In acute stage of stroke there is sharply increasing morbidity of sleep apnea hypopnea syndrome. Our suppose that treatment with noninvasive ventilation for patients with acute ischemic stroke should improve the functional prognosis（measuring with 90d modified Rankin score）.
The purpose of our study is to determine the safety and efficacy of the combination of erythropoietin (EPO) and granulocyte-colony stimulating factors (G-CSF) in patients with neurological diseases. To be specific, our clinical study is expected that the combination injection of EPO and G-CSF shows neurotrophic and neuroprotective effects by facilitating endogenous repair process in patients with neurological diseases including stroke, cerebral palsy, or atypical parkinsonism. Therefore, we will apply our original treatment technique in patients with neurological diseases, which is expected to overcome current ethical and technical limitations of less evidenced functional recovery, hematological changes, and side effects. Eventually, We will establish a comprehensive clinical background about neurotrophic and neuroprotective effects of this hematopoietic growth factors therapy.
Stroke is the first and the fourth leading cause of death in the United States and China, respectively. Disruption of cerebrovascular vulnerable atherosclerotic plaque is the major etiology of ischemic stroke. Therefore, early detection and treatment of vulnerable plaques occurring at the feeding arteries to brain (cerebral arteries) will be helpful for prevention of stroke. Atherosclerosis is a systemic disease that usually affects multiple vascular beds. Previous studies have shown that these high risk lesions in different segments of cerebral arteries (intracranial and extracranial arteries) might be racially specific. It is reported that, in stroke patients, intracranial vulnerable plaques are prevalent in Asian populations whereas atherosclerosis more frequently involves extracranial carotid arteries in American subjects. However, these findings are based on angiographic imaging approaches via measuring arterial luminal stenosis. Because the atherosclerotic plaque often appears as outward expansion, namely positive remodeling during progression, measuring luminal stenosis will underestimate the disease severity. Hence, directly viewing the plaque in the vessel wall is strongly suggested in order to objectively evaluate the cerebrovascular vulnerable plaque. High resolution, black-blood magnetic resonance (MR) imaging has been widely used to accurately characterize carotid vulnerable plaque in the last two decades. The aim of using MR black-blood techniques is to suppress the blood signal (black) to enhance the signal contrast between the vessel wall and blood in the arterial lumen. Excellent agreement has been achieved between MR imaging and histology in identification of plaque components, such as intraplaque hemorrhage and lipid core. For assessing carotid plaque, MR imaging is superior to computed tomography and ultrasound imaging techniques due to its advantages including noninvasive imaging, lack of ionizing radiation, excellent soft tissue resolution, and multi-parametric image acquisition. The Investigators hypothesize that there are specific characteristics in carotid vulnerable plaques in Chinese patients with ischemic cerebrovascular events such as ischemic stroke and transient ischemic attack (TIA). This study seeks to investigate the characteristics of vulnerable plaque in carotid arteries using high resolution, black-blood MR imaging in patients with recent TIA or ischemic stroke. This is a cross-sectional, multicenter study. A total of 1000 patients will be recruited from more than 10 different hospitals across China within 3 years. All patients will undergo MR imaging for brain and carotid arteries within two weeks after symptom onset. The prevalence of carotid vulnerable plaque and its correlations with brain ischemic lesions, traditional risk factors, and regional distribution of China will be determined.
This trial is an prospective, government-funded registration study that will observe the safety and effectiveness of intracranial stenting for preventing stroke during a mean follow-up of 12 months in patients with symptomatic stenosis of a major intracranial artery (MCA, carotid, vertebral, basilar). This trial will be launched by Xuanwu Hospital, Capital University of Medical Science, with 20 collaborators participating. Enrollment will begin in 2013, and it aims to have a sample size of 840 subjects in 2 years. The trial is scheduled to complete in 2015. As we know, SAMMPRIS is flawed with defect in design, heterogeneity in experience and credentials of operators and high rate of complication; Whether the interventional therapy for symtomatic intracranial artery stenosis is effective or not remained resolved. This trial has been modified based on SAMMPRIS in order to acquire the data for China: Technique, experience, and credential of the operators are closely related with perioperative complications in PTAS. The investigators select 50 large-scale medical centers for participation on the basis of geographical distribution. All the participants are ranked as top in China. They have the most experienced surgeons or interventionist in China, and are fully qualified for this trial. This will guarantee the success and safety of technique, maintain the continuity of operator's experience, and make the complication rate as low as possible.
