About this study
Stroke is the second largest cause of death globally after ischemic heart disease.Of the total number of prevalent strokes, 84.4% are ischemic. Reperfusion therapy is the most important treatment for acute ischemic stroke (AIS) ,including intravenous thrombolysis and/or endovascular treatment.However,the most serious and common complication with reperfusion therapy is hemorrhage transformation(HT),which significantly increases disability and mortality. The fundamental mechanism leading to post-stroke HT is the disruption of the blood brain barrier(BBB) and increase of permeability.Endocan plays a critical role in vascular inflammatory responses by enhances the production of pro-inflammatory cytokines by endothelial cells,the expression of adhesion molecules such as inter-cellular adhesion molecule-1(ICAM-1) and vascular cell adhesion molecule-1(VCAM-1),and the adhesion of leukocytes to endothelial cells. Endocan significantly decreases levels of zonula occludens(ZO-1) and occludin which are tight junction proteins that play major roles in the maintenance of vascular barriers. Endocan could induce vascular endothelial growth factor-A(VEGF-A) and facilitate the binding of VEGF-A to its receptor(VEGFR-2) to enhanced endothelial permeability.Therefore,endocan is a reliable biomarker of endothelial dysfunction, which may be associated with disruption of the BBB. In this context, the investigators hypothesized that elevated pretreatment serum endocan levels might be independently associated with HT after reperfusion therapy in the acute phase of ischemic stroke. Serum endocan,ICAM-1,VCAM-1 and matrix metalloproteinase-9(MMP-9) levels will be determined by enzyme-linked immunosorbent assay(ELISA) in blood samples obtained at baseline (pretreatment) and at 12,24 hours after reperfusion therapy in patients with acute stroke and in healthy subjects.In the present study,the investigators attempt to investigate whether high levels of endocan are associated with HT in patients who received reperfusion therapy.In addition,the investigators explore the association between serum endocan and early neurological deterioration and unfavourable short-term prognosis.

enzyme-linked immunosorbent assay(ELISA)Diagnostic test
Peripheral blood samples will be drawn from each patient at study entry (before reperfusion therapy) and at 12,24 hours after reperfusion therapy.Serum will be immediately separated by centrifugation at 3000 rpm for 15 minutes and stored at -80°C. Endocan,ICAM-1,VCAM-1,MMP-9 levels will be determined in duplicate by commercially available enzyme-linked immunosorbent assay (ELISA).

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Hemorrhagic Transformation after reperfusion therapy
Patients will undergo the cranial CT at 24 to 48 hours after reperfusion therapy to identify intracranial hemorrhage
Measured: At 24 to 48 hours after reperfusion therapy
Secondary outcomes (2)
Incidence of early neurological deterioration
Either death or an increase in the NIHSS score by ≥4 points from baseline to 24 hours after reperfusion therapy
