Brief Summary:
Vascular endothelial growth factor (VEGF) and Endostatin (ES) participate angiogenesis after cerebral ischemia. Circulating endothelial progenitor cells (EPCs) also play a crucial role in neovascularization and tissue repair after acute ischemic stroke (AIS). The investigators sought to compare the expression of VEGF and ES in serum and the circulating EPCs in patients after AIS with that of healthy control subjects. The investigators obtained peripheral blood and serum samples from study subjects. EPCs in blood samples from AIS patients and healthy controls were quantified by flow cytometry 1 day, 3 days, 5 days and 7 days after AIS. VEGF and ES were measured by enzyme linked immunosorbent assay at the same time points. The relation between them and the relation of them to prognosis of such patients with acute ischemic stroke were assessed.

Acute ischemic stroke
Patients who suffered from acute ischemic stroke within 12 hours for the first time before entry into the study, and had a score between 6 and 25 on the National Institutes of Health Stroke Scale (NIHSS).

Primary Outcome Measures :
  1. Modified Rankin Scale scores [ Time Frame: 3 months ]

    0 = No symptoms; 1 = No significant disability. Able to carry out all usual activities, despite some symptoms; 2 = Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities; 3 = Moderate

    - Page 3 of 4 [DRAFT] - disability. Requires some help, but able to walk unassisted; 4 = Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted; 5 = Severe disability. Requires constant nursing care and attention, bedridden, incontinent; 6 = Dead.

Secondary Outcome Measures :
  1. Glasgow Outcome Scale scores [ Time Frame: 3 months ]
    Glasgow Outcome Scale 1 = death; Glasgow Outcome Scale 2 = vegetative state; Glasgow Outcome Scale 3 = severe neurological deficit; Glasgow Outcome Scale 4 = mild neurological deficit and Glasgow Outcome Scale 5 = premorbid level of functioning or completely recovery.
