Objective:To study the influence of reperfusion after ischemia for different time on cerebral infarction volume and neurological function of the focal ischemia reperfusion model in rats.

Infarction of the Cerebellum Dignosis by MRI;

Methods To adopt the local cerebral ischemia model by infarct middle cerebral artery in rats and to observe the effect on the nervous function and the area of cerebral infarction of cerebral ischemia of rat model.

Infarctions overlapping different territories accounted to individual groups.

Study of Myocardial Damage in Ischemia and Infarct by Acoustic Densitometry;

Vascular dementia(VaD)subtypes include multi-infarct dementia, subcortical ischemic vascular dementia, strategic-infarct dementia, etc.

Brain damage was appreciated according to the neurological score,the infarct sizes and the histotogical changes induced by focal cerebral ischemia.

Evaluation of relationship between remodeling of carotid atherosclerosis and hs-CRP levels in patients with cerebral infarction;

Correlative Analysis of Ultrasonography in carotid artery and Hemodynamics in Intracranial artery for those Cerebral Infarction patients;

Diagnostic value of DWI and FLAIR in superacute and acute cerebral infarction;
