G-CSF对心肌梗死合并心力衰竭患者外周血内皮祖细胞和炎性因子的影响

目的 观察应用粒-细胞集落刺激因子(G-CSF)动员内皮祖细胞(EPCs)治疗心肌梗死合并心衰患者合并外周血内皮祖细胞(EPCs)和炎性因子的变化,探讨动员剂G-CSF对外周血及炎性因子的影响.方法 38例心肌梗死合并心衰患者被随机分为G-CSF(600 μg/d,共7 d)组和对照组,12例健康者为空白组.分离、培养EPCs并测定其数量.应用酶联免疫法及放射免疫法检测两组患者及10例健康者血C-反应蛋白(CRP)、白细胞介素-6 (IL-6)、肿瘤坏死因子-α(TNF-α)、基质细胞衍生因子-1(stromal cell-derived factor-1,SDF-1) 的水平.结果 心肌梗死合并心衰患者EPCs数量和血CRP、IL-6、TNF-α及SDF-1水平均明显高于健康者(P<0.05);两组治疗后各组与治疗前相比差异有统计学意义(P<0.05);治疗组CRP水平较对照组明显降低(P<0.01);治疗组血浆SDF-1水平较对照组明显升高 (P<0.01),SDF-1浓度与循环EPCs数量呈正相关;治疗组与对照组相比,IL-6、TNF-α虽有所下降,但差异无统计学意义(P＞0.05).结论 G-CSF可有效动员急性心肌梗死患者外周血EPCs,亦可降低CRP、改变SDF-1的水平.

Effects of granulocyte colony-stimulating factor on EPCs and inflammatory factors in patients with myocardial infarction and heart failure

Objective To investigate the effects of granulocyte colony-stimulating factor(G-CSF) on endothelial progenitor cells(EPC) and inflammatory factors in patients with myocardial infarction(MI) and heart failure(HF).Methods Thirty-eight patients with MI and HF were randomly divided into G-CSF group and control group,while 12 healthy people were enrolled as health group.The absolute count of CD34 positive cells in peripheral blood was enumerated with flow cytometry.Plasma levels of C-reactive protein(CRP),inter ...
