Our study is to evaluate the early effectiveness of a hospital stroke unit (SU). Methods Three hundred and ninety-two patients who had suffered from acute strokes and who were admitted to our hospital between December 2001 and January 2003 were recruited for this controlled study. All patients were sent at random to either the SU or the general ward (GW) for treatment. The following indices were measured by: Barthel Index (BI),National Institute of Health Stroke Scale (NIHSS),Oxford Handicap Scale (OHS). Results The mean change in BI score between the day of admission and the day of discharge was 20.00±24.36 for the SU group and 10.63±23.59 for the GW group. A difference that is statistically significant ( P =0.000). The mean change in NIHSS score was -2.01±6.61 for the SU group and 0.55±7.44 for the GW group. A difference that is also statistically significant ( P =0.000). Finally,the mean change in OHS score was -0.74±1.04 for the SU group and -0.28±0.98 for the GW group,also a statistically significant difference ( P =0.000). Among SU patients,patient satisfaction was higher ( P =0.000),the rehabilitation success rate was higher ( P =0.000),and there were fewer complications ( P =0.000).Conclusion Compared to GW patients,stroke patients treated in a special SU were able to return to normal daily activities earlier,with better social abilities,and have reduced neurological defects,without increasing the overall economic burden. 展开更多

BACKGROUND: Acute stroke unit (stroke care unit) is developing in some domestic large-sized hospitals, but most stroke patients need stroke rehabilitation unit therapy, so setting stroke rehabilitation unit in medium-sized comprehensive community hospital (secondary hospital), where medical facility is relatively insufficient, is a new pathway to satisfy stroke patients. OBJECTIVE: To observe the comprehensive effect of developing stroke rehabilitation unit based on the facility of secondary hospital and its feasibility. DESIGN: Non-randomized concurrent controlled observation SETTING: Department of Neurology, Beijing Longfu Hospital PARTICIPANTS: Totally 264 stroke reconvalescents who suffered stroke for 7 days and received treatment in the Department of Neurology, Beijing Longfu Hospital during June 2003 to June 2005 were involved in the study. All the involved patients were confirmed by CT or MRI. The patients were scored by using Modified Edinbergh-Scandinavia stroke scale (SSS) 〉 16 points. Written informed consents were obtained from all the patients. The patients were assigned into 2 groups according to the willing of patients and their relatives: (1)treatment group, in which, there were 134 patients, 76 males and 58 females, aged 43 to 74 years; cerebral infarction was found in 116 cases and cerebral hemorrhage in 18 cases;(2) control group, in which, there were 130 patients, 66 males and 64 females, aged 45 to 77 years, cerebral infarction was found in 115 cases and cerebral hemorrhage in 15 cases. There were significant differences in baseline data of the patients between two groups. METHODS: A same basic treatment was conducted in the patients of the two groups. (1) Patients in the treatment group admitted to stroke rehabilitation unit and received comprehensive rehabilitation treatment. The rehabilitation flow-sheet: randomization-letting the patients of treatment group go into the unit-making comprehensive assessment in the initial stage-making therapy plan-talking with patients and their other family members-general rehabilitation-making metaphase assessment-adjusting therapy plan-making final assessment-letting the patients discharge and doing follow-up visits. (2) The patients in the control group admitted to common wards, and they were encouraged to do activities by themselves in the early stage, but did not receive rehabilitation training under the instructions from professional physicians. MAIN OUTCOME MEASURES: The following assessments were conducted on admission and 7 and 28 days after admission: (1) Severity of stroke and motor function: scored as 0 to 45 points by SSS, the higher points, the severer damage. (2)Activities of daily living: Evaluated by Barthel index, 110 points in total, 110 points meant normal, 0 point meant extremely poor. (3)Mental status: evaluated by Hopkin's symptom scale with a 5-point scoring. The symptom was scored with low to high points. (4)Cognitive function: Quantification measurement was conducted with LOTCA method. The higher points, the better therapeutic effects. RESULTS: (1) Three cases dropped out and one died in the treatment group, 11 cases dropped out and 4 died in the control group. (2)The neurologic impairment points on 7 and 28 days after therapy in the treatment group were lower than those in the control group separately [7 days:(9.73±6.43) points vs. (12.63± 7.87) points, t =2.28, P〈 0.05;28 days:(7.88±4.81) points vs. (9.84±7.03)points, t =2.04, P〈 0.05]. Barthel index on 7 and 28 days after therapy in the treatment group were higher than those in the control group separately [7 days:(54.28±8.38) points vs. (39.76±7.31) points, t =2.206, P 〈 0.05; 28 days: (89.72±7.94) points vs. (67.34±8.63) points, t =2.812, P 〈 0.01]. (4) Patients were allocated into different age groups based on age and evaluated with LOTCA. Results showed that there were no significant differences among different age groups (P 〉 0.05). (5) Totally 160 patients in the two groups accomplished the Hopkin's test, among them, 94 (58.7%) had different mental disorders; Among the patients with mental disorder, depression, obsessive-compulsive and anxiety were found mostly, being 53.8%, 52.5% and 46.2%, respectively. CONCLUSION: (1) Developing stroke rehabilitation unit therapy in the secondary hospital can obviously improve the motor function and activities of daily living of stroke reconvalescents. (2) More than half of the stroke reconvalescents accompany the symptoms of depression, obsessive-compulsive, anxiety and other mental disorders. (3) The cognitive function of stroke reconvalescents is not related to age. 展开更多

Introduction: Palliative care, firstly used for chronic diseases, is currently indicated for some acute pathology such as Stroke. Its implementation improves the quality of care for end-of-life patients. The aim of our study is to report a series of patients who died in the intensive care stroke unit of Brazzaville. Method: It was a descriptive study of a series of 13 cases of severe stroke, admitted to the intensive care unit of the university hospital of Brazzaville, between January 2015 and December 2017. Sociodemographic, clinical, paraclinical and prognostic variables were studied. Result: The mean age of the patients was 46 ± 11.5 years with a male predominance in 69.2% (n = 9). They were all hypertensive. The motor deficit and consciousness disorder association was the reason for admission in 84.6% (n = 11) and an epileptic seizure of 15.4% (n = 2). The mean NIHSS at admission was 21 ± 5, that of Glasgow 6 ± 3. Stroke was hemorrhagic in 84.6% (n = 11) and malignant infarction in 15.4% (n = 2). All of these patients received invasive resuscitation with assisted ventilation and all died within 8 days of admission. Conclusion: The issue of limitation of care deserves to be debated, and is proposed on a case-by-case basis, in the face of a serious stroke. Therapeutic relentlessness is not only expensive, but also raises the problem of suffering of the individual at the end of life. 展开更多

There is a clear benefit in caring for stroke patients in stroke care units. Access to these centres is limited particularly in the rural setting. Certified stroke care units in the private health care setting are also unheard of. The superiority of these units is thought to be due to better adherence to processes of care (early utility of CT scan, allied health input within 24 hours, neurological observations, DVT prophylaxis and appropriate use of antiplatelet and anticoagulant use). We audited care of 100 patients who presented to the St. John of God Hospital (rural private hospital) over a period of 3 years. This included baseline demographics, adherence of processes of care, utility of appropriate investigations, and outcome measures such as discharge destination, level of function at discharge and complication rates. These data were compared with the national stroke report (AuSCR) and adherence to processes of care was compared with the SCOPE study (the first study to establish the benefit of POC). When compared with data from the AuSCR national report 2012, we found a higher mortality rate, an increased rate of disability on discharge, and a mixed adherence to processes of care. We also found a significant proportion of patients (40%) who were eligible to receive thrombolysis but did not. Overall we found that there were significant strengths to be drawn upon in the rural private healthcare setting and a more organised approach could improve outcomes. 展开更多

Hyodeoxycholic acid(HDCA) is a bioactive compound extracted from calculus bovis. When combined with cholic acid, baicalin and jas-minoidin, HDCA prevents hypoxia-reoxygenation-induced brain injury by suppressing endoplasmic reticulum stress-mediated apoptotic signaling. However, the effects of HDCA in ischemic stroke injury have not yet been studied. Neurovascular unit(NVU) dysfunction occurs in ischemic stroke. Therefore, in this study, we investigated the effects of HDCA on the NVU under ischemic conditions in vitro. We co-cultured primary brain microvascular endothelial cells, neurons and astrocytes using a transwell chamber co-culture system. The NVU was pre-treated with 10.16 or 2.54 μg/mL HDCA for 24 hours before exposure to oxygen-glucose deprivation for 1 hour. The cell counting kit-8 assay was used to detect cell activity. Flow cytometry and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling were used to assess apoptosis. Enzyme-linked immunosorbent assay was used to measure the expression levels of inflammatory cytokines, including interleukin-1β, interleukin-6 and tumor necrosis factor-α, and neurotrophic factors, including brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor. Oxidative stress-related factors, such as superoxide dismutase, nitric oxide, malondialdehyde and γ-glutamyltransferase, were measured using kits. Pretreatment with HDCA significantly decreased blood-brain barrier permeability and neuronal apoptosis, significantly increased transendothelial electrical resistance and γ-glutamyltransferase activity, attenuated oxidative stress damage and the release of inflammatory cytokines, and increased brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor expression. Our findings suggest that HDCA maintains NVU morphological integrity and function by modulating inflammation, oxidation stress, apoptosis, and the expression of neurotrophic factors. Therefore, HDCA may have therapeutic potential in the clinical management of ischemic stroke. This study was approved by the Ethics Committee of Experimental Animals of Beijing University of Chinese Medicine(approval No. BUCM-3-2016040201-2003) in April 2016. 展开更多

目的本研究旨在构建并研发一种基于低成本惯性测量单元(inertial measurement unit,IMU)信号的上肢多关节运动状态识别系统,用于快速、可靠地解码人类活动中的上肢多关节(前臂、肘关节、肩关节)运动状态,为卒中后上肢康复评估中的运动... 目的本研究旨在构建并研发一种基于低成本惯性测量单元(inertial measurement unit,IMU)信号的上肢多关节运动状态识别系统,用于快速、可靠地解码人类活动中的上肢多关节(前臂、肘关节、肩关节)运动状态,为卒中后上肢康复评估中的运动模式识别和日常运动监测提供支持。方法本研究纳入4名健康受试者,通过部署于手腕和上臂的IMU采集受试者的6维(3轴加速度+3轴角速度)运动信号,每名受试者重复10次。基于Fugl-Meyer运动功能评定量表上肢部分的屈肌协同运动,设计8个子任务,每个任务对应前臂(是否旋后)、肘关节(是否屈曲)、肩关节(是否上提)的三元状态标签。构建基于单任务迁移的多标签分类框架(即独立训练单关节分类器后融合输出)。在算法层面,对比了传统机器学习方法(时频域特征+随机森林)与深度学习算法(长短期记忆网络的网络端到端学习)。通过5折交叉验证评估上肢多关节运动状态识别系统的准确性,并设计消融实验分析传感器配置(如单腕vs.腕+臂)对解码性能的影响,以探索硬件优化空间。结果研究共采集4名健康受试者的320个运动数据样本,结果提示,本研究设计的运动状态识别系统在上肢多关节状态解码中表现良好:传统机器学习方法在肘关节状态分类中的平均准确率为79.37%,而深度学习模型IBNet(Inception-BinaryNet)的准确率达到87.5%,显示出更强的模式学习能力。消融实验发现,仅使用手腕IMU时,肘关节状态分类准确率超过了双IMU配置(92.5%vs.87.5%),且在其他任务中差异不显著,这表明优化传感器部署(如减少上臂IMU)可降低系统复杂度,同时保持较高性能。结论本研究成功构建了一种基于低成本IMU的上肢运动状态识别系统。研究发现,深度学习算法在解码复杂运动模式时优于传统机器学习,且单手腕IMU在特定任务中可替代双传感器配置,为硬件优化提供了依据。 展开更多
