Summary

Moyamoya disease is a chronic cerebrovascular disease，The typical pathological manifestations are the stenosis or occlusion of the distal internal carotid artery and/or middle cerebral artery, and the proximal anterior cerebral artery. Meanwhile, the abnormal vascular net, which is the smokey vessel, occurs at the bottom of the brain. Currently the pathogenesis of this disease is unknown. Limited studies have reported the expression of endothelial progenitor cells (EPCs) in moyamoya disease, but the results were inconsistent. Some investigators believe that the number of EPCs in peripheral blood of patients with moyamoya disease is increased, while others believe that the number of EPCs in peripheral blood of moyamoya patients is reduced. Therefore, the investigators need to find a more accurate detection method to confirm the growth of EPC in patients with moyamoya disease. At the same time, whether there is endothelial injury in patients with smoke disease, and the expression of endothelial cells (CEC) in patients with smoke disease, there is no research on this aspect at home and abroad.

Detailed description

Objective: Detect the expression of endothelial progenitor cells and endothelial cells from peripheral blood of patients with moyamoya disease, and to assess the relationship between clinical characteristics. Design: A single center study, and planned to enroll 120 patients. The present study was to detect the quantities of EPC from peripheral blood in Moyamoya disease by flow cytometry, and to identify the relationship of endothelial progeIlitor cells and effect of the revascularization on Moyamoya disease. The present study also use cerebral ischemia animal model foe intervention experiment, to explore whether EPC can promote vascular remodeling effect of ischemic cerebrovascular disease, and to provide new thought for the treatment of chronic cerebrovascular disorder.
