Stenting for symptomatic intracranial arterial stenosis in China: 1-year outcome of a multicentre registry study.

Background And Purpose: A multicentre prospective registry study of individually tailored stenting for a patient with symptomatic intracranial atherosclerotic stenosis (ICAS) combined with poor collaterals in China showed that the short-term safety and efficacy of stenting was acceptable. However, it remained uncertain whether the low event rate could be of a long term. We reported the 1-year outcome of this registry study to evaluate the long-term efficacy of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.

Comorbidity Burden of Dementia: A Hospital-Based Retrospective Study from 2003 to 2012 in Seven Cities in China.

Dementia is increasing dramatically and imposes a huge burden on society. To date, there is a lack of data on the health status of patients with dementia in China. In an attempt to investigate the comorbidity burden of dementia patients in China at the national level, we enrolled 2,938 patients with Alzheimer's disease (AD), vascular dementia (VaD), or other types of dementia, who were admitted to tertiary hospitals in seven regions of China from January 2003 to December 2012.

Comorbidity burden of patients with Parkinson's disease and Parkinsonism between 2003 and 2012: A multicentre, nationwide, retrospective study in China.

Parkinson's disease (PD) and Parkinsonism are common neurodegenerative disorders with continuously increasing prevalence, causing high global burdens. However, data concerning the comorbidity burden of patients with PD or Parkinsonism in China are lacking. To investigate the health condition and comorbidity burden, a total of 3367 PD and 823 Parkinsonism patients were included from seven tertiary hospitals in seven cities across China from 2003 to 2012.

Protective effect of tetrahydroxy stilbene glucoside on learning and memory by regulating synaptic plasticity.

Damage to synaptic plasticity induced by neurotoxicity of amyloid-beta is regarded to be one of the pathological mechanisms of learning and memory disabilities in Alzheimer's disease patients. This study assumed that the damage of amyloid-beta to learning and memory abilities was strongly associated with the changes in the Fyn/N-methyl-D-aspartate receptor 2B (NR2B) expression. An APP695V7171 transgenic mouse model of Alzheimer's disease was used and treatment with tetrahydroxy-stilbene glucoside was administered intragastrically.

Protective Effects of Colivelin Against Alzheimer's Disease in a PDAPP Mouse Model.

Background: Alzheimer's disease (AD) is characterized with progressive memory loss and severe cognitive impairments, which affect everyday life and human health in the elderly. It is required that an effective and safe protective reagent against AD should be developed. It has been reported that humanin (HN) exerts neuroprotective effects against AD.

Safety and Efficacy Analyses of Angioplasty and Stenting for Severe Intracranial Arterial Stenosis: A Single-Center Retrospective Study in China.

Background: The value of percutaneous transluminal angioplasty and stenting (PTAS) in the context of aggressive medical treatment for severe intracranial artery stenosis (ICAS) is under debate. This study compared the effects of PTAS and aggressive medical treatment in patients with severe ICAS and transient ischemic attack or stroke.

Material And Methods: A retrospective cohort study was performed.

Thirty-Day Outcome of a Multicenter Registry Study of Stenting for Symptomatic Intracranial Artery Stenosis in China.

Background And Purpose: Although recent trials have suggested that stenting is worse than medical therapy for patients with severe symptomatic intracranial atherosclerotic stenosis, it is not clear whether this conclusion applies to a subset of patients with hypoperfusion symptoms. To justify for a new trial in China, we performed a multicenter prospective registry study to evaluate the safety and efficacy of endovascular stenting within 30 days for patients with severe symptomatic intracranial atherosclerotic stenosis.

Methods: Patients with symptomatic intracranial atherosclerotic stenosis caused by 70% to 99% stenosis combined with poor collaterals were enrolled.

Objective: To observe the effect of tetrahydroxy stilbene glucoside (TSG) on the behavior of APP695V717I transgenic mouse models and the expression of autophagy-associated proteins Beclin-1 and LC3-II.

Methods: Forty 3-month-old APP695V717I transgenic mice were randomized equally into either a TSG group (n = 20) or a model group (n = 20). A normal control group consisted of C57BL/6J mice of the same age and background (n = 20).

Common Aging Signature in the Peripheral Blood of Vascular Dementia and Alzheimer's Disease.

Alzheimer's disease (AD) and vascular dementia (VaD) are the two most dominant forms of dementia in elderly people. Due to the large overlap between AD and VaD in clinical observations, great controversies exist regarding the distinction and connection between these two types of senile dementia. Here for the first time, we resort to the gene expression pattern of the peripheral blood to compare AD and VaD objectively.

General public perceptions and attitudes toward Alzheimer's disease from five cities in China.

Alzheimer's disease (AD) is the most common type of dementia affecting the aged population worldwide, yet its social perceptions have been less studied. To investigate the perceptions and attitudes toward AD in the Chinese population, a cross-sectional face-to-face survey of 2,000 randomly selected adults was conducted in five representative cities of China. This survey focused on the fear of AD, and the relationship between this variable and each studied factor was analyzed using univariate analysis and multivariate regression analysis.

Tetrahydroxy stilbene glucoside reduces the cognitive impairment and overexpression of amyloid precursor protein induced by aluminum exposure.

Objective: Excessive aluminum (Al) exposure impairs neurocognitive function in humans and animals. Epidemiologic studies have shown a potential linkage between chronic Al exposure and Alzheimer's disease. The present study aims to evaluate the effects of tetrahydroxy stilbene glucoside (TSG), the extract from herbal medicine Polygoni Multiflori, on cognitive impairment and the over-expression of hippocampal amyloid precursor protein (APP) induced by chronic exposure to Al in rats.

Insertional mutagenesis at positions 520 and 584 of adeno-associated virus type 2 (AAV2) capsid gene and generation of AAV2 vectors with eliminated heparin- binding ability and introduced novel tropism.

Recombinant adeno-associated virus (AAV) vectors are promising in the context of gene therapy because of their ability to mediate efficient gene transfer and stable gene expression. AAV2 uses heparin sulfate as its primary receptor, which is widely expressed on the various tissues and organs. This limits the application of AAV2 in targeting specific tissues.
