Abstract 【Objective】 To investigate the relationship between circulating endothelial progenitor cells (EPCs) and plasma stromal cell-derived factor-1α(SDF-1α). 【Methods】 A total of 153 patients with TIA within 24 hours were collected and divided into high-risk TIA group (83 cases) and non high-risk TIA group (70 cases). The clinical data of patients were collected, the number of circulating EPCs was measured by flow cytometry, and the concentration of plasma SDF-1αand vascular endothelial growth factor (VEGF) was measured by enzyme-linked immunosorbent assay . 15 healthy volunteers were selected as normal control (NC). According to the time of admission, the circulating EPCs of the top 15 patients in the high-risk TIA group and the non high-risk TIA group were collected. The proliferation ability of circulating EPCs in the three groups was measured by MTT method, and the migration ability of EPCs was measured by Boyden chamber. 【Results】 Compared with the non high-risk group TIA, the high-risk group TIA had a higher age, and more patients with hypertension and diabetes, and three triglycerides, total cholesterol and low density lipoprotein in peripheral blood were also higher. There was no significant difference in smoking, body mass index and homocysteine between the two groups (P>0.05). Circulating EPCs, SDF-1α and VEGF in the non high risk TIA group was higher than that in the high-risk TIA group (P<0.01). Multivariate regression analysis showed that age, hypertension, diabetes, total cholesterol, SDF-1αand EPCs were high-risk TIA risk factors, and EPCs were high-risk TIA protective factors. Compared with the NC group, the proliferation and migration ability of EPCs isolated and cultured for 72 hours in the high-risk TIA group and the non high-risk TIA group decreased (P<0.05). Compared with the non high-risk TIA group, the proliferation and migration of cells in the high-risk TIA group decreased (P<0.01). 【Conclusion】 The level of circulating EPCs and plasma SDF-1αmay be used as an index to evaluate the severity of TIA. The decline of proliferation and migration ability of circulating EPCs may lead to high-risk TIA.
