The metabolic syndrome represents a complex combination of the symptoms obesity, hypertension, diabetes, and dyslipoproteinemia. Insulin resistance is the major pathophysiologjcal basis of the metabolic syndrome. There is a close association between the metabolic syndrome and its various components and vascular cognitive impairment. This article briefly reviews the mechanisms of metabolic syndrome caused vascular cognitive impairment, and summarizes the significance of controlling metabolic syndrome on the prevention and treatment of vascular cognitive impairment.

Objective:To investigate the effect of edaravone injection on the neuron-specific enolase(NSE) concentration in serum from patients with acute cerebral infarction.Methods:The NSE concentrations in serum from 35 patients were measured by an ELISA method.Neurological deficit was scored for clinical effect assessment.Results:Serum NSE levels and neurological deficit scores in edaravone treating group significantly decreased at d 3 compared with those in routine therapy group((P

Objective:To analyze the correlation between intra-extracranial arterial stenosis and silent cerebral infarction(SCI) in the elder with essential hypertension(EH). Methods:The results of color duplex ultrasonography(Duplex) and digital subtraction angiography(DSA) examination of 86 patients with essential hypertension complicated silent cerebral infarction were analyzed.The incidence of intra-and extracranial arterial stenosis and arthrosclerosis plaque were calculated.The comparative value of Duplex and DSA for evaluating atherosclerosis of extracranial carotid artery was analyzed using statistic methods. Results:The incidence of arthrosclerosis plaque was higher in SCI group than that in normal control group(62.79%,24%,P

Epidemiological studies indicated that dietary tiber was inversely associated with stroke risk.Epidemiological studies have confirmed that increased dietary fiber intake can reduce the risk of stroke.Animal experiments and clinical studies have shown that dietary fiber intake may reduce the incidence of stroke by reducing vascular risk factors,such as hypertension,diabetes,dyslipidemia,and obesity.The direct mechanism of increased dietary fiber intake reducing stroke risk remains to be further studied.Clinicians should pay attention to the important role of dietary fiber,guide the patients with stroke and individuals at risk of stroke to increase consumption of fiber-rich fruits and vegetables.

Cervical arterial dissection is an important cause resulting in stroke, particularly in young adults. The clinical manifestation of cervical arterial dissection may be various, and imaging examinations have a great value in the diagnosis of cervical arterial dissection. At present, anticoagulation and anti-platelet aggregation are the most important medication, while intravascular intervention is a new option for patients failed to respond to medical treatment. This article reviews the recent progress in the diagnosis and treatment of cervical arterial dissection.

arotid artery stenosis is a common clnical disease, and its treatment includes drug therapy, carotid endarterectomy and carotid angioplasty and stenting. This article reviews the advances in the management of carotid artery stenosis.

Carotid atherosclerosis is a major cause of ischemie stroke. Understanding the compositions of carotid plaque arid preventing plaque rupture are of importance to reduce the risk of ischemic stroke. Magnetic resornance imaging (MRI) is noninvasive, highly reproducible, does not involve exposure to ionizing radiation. It is one of the most potential imaging tools for carotid atherosclerotic plaques. This article reviews the application of MRI in the imaging of carotid atherosclerotic plaques.

Moyamoya disease is an uncommon cerebral disease, but its morbidity is relatively high in East Asian populations. Ivy sign refers to the dot or linear high signal phenomenon in MRI T1 enhanced sequence in patients with moyamoya disease. It mainly distributes in the pial surface of cerebral cortex or within subarachnoid space. It has important significance for diagnosing moyamoya disease and assessing the staging and prognosis of moyamoya disease. This article briefly reviews this imaging finding and its significance.

Most patients with ischemic cerebrovascular diseases,after treated in hospitals during the acute stage,can return home or back to the community.Therefore,secondary prevention of the disease in the community is very important.

Endovascular intervention is an effective method in the treatment of cerebrovascular stenosis. With the advancement of techniques and improvement of equipment, the application area of this treatment is expanding and the number of patients treated is increasing. Accordingly, the use of contrast media is improving continuously in endovascular intervention. An increasing number of contrast media-related complications have also been reported. This paper briefly reviews the contrast media-related complications and their management in endovascular intervention.
