摘  要:目的研究不同脑血管狭窄程度及脑血管支架术对患者外周血中树突状细胞(DCs)比例的影响。方法选择自2009年11月至2010年2月、自2010年8月至2010年12月存南方医科大学珠汀医院神经内科住院患者63例,依据脑血管造影(DSA)检查结果,分为DSA未见异常组即对照组(CO)、轻中度狭窄组(MsG)、重度狭窄组(SsG)、支架术后组(SiG)。流式细胞四色分析法检测各组患者外周血中DCs各亚型的比例。结果各组患者外周血中骨髓样树突状细胞(mDCs)的比例比较差异有统计学意义(P=0.000),其中CG与SsG差异有统计学意义(P〈0.05),MsG与SsG差异有统计学意义(P〈0.05)。类浆样树突状细胞(pDCs)的比例在各组间比较差异没有统计学意义(P=0.065)。结论脑血管狭窄程度对mDCs亚型的比例存在影响,狭窄程度越草mDCs比例越低:支架置人对患者外周血中DCs各亚型比例不造成影响.Objective To study the changes of proportion of peripheral blood dendritic cells (DCs) in patients with different degrees of cerebrovascular stenosis and after stenting, and explore the relation between DCs level and cerebrovascular stenosis. Methods Sixty-three patients, admitted to our hospital from November 2009 to February 2010 and from August 2010 to December 2010, were divided into control group (CG, n=9), mild/moderate stenosis group (MsG, n=17), severe stenosis group (SsG, n=30) and stent implanted group (SiG, n-7) according the results of digital subtraction angiography (DSA) and their clinical situation. Flow cytometry 4-color analysis was employed to detect the proportion of DCs subtypes in the peripheral blood. Results The percentage of peripheral blood myeloid dendritic cells (mDCs) was significantly different in the above groups (P=0.000): that between CG and SsG, and that between MsG and SsG were significantly different (P〈0.05). Whereas, no obvious difference was founded in plasmacytoid dendritic cells (pDCs) between each 2 groups (P=0.065). Conclusion The percentage of mDCs suggests the alterations of different degrees of cerebrovascular stenosis: the severer the stenosis, the lower the percentage of mDCs; stent implantation will not affect the distribution of DCs subtypes
