目的：观察粒细胞集落刺激因子（G-CSF）动员内皮祖细胞（EPCs）对心肌梗死患者心功能的影响。方法：收集心肌梗死后心衰患者80例，随机分为常规治疗对照组和粒细胞集落刺激因子（G-CSF）动员治疗观察组，每组40例。 EPCs 使用流式细胞仪检测。结果：观察组治疗前患者 EPCs 比例为（0．11±0．04）％，治疗后 EPCs 比例升高为（5．32±1．06）％（P ＜0．01）。治疗前2组 LVEF、LVEDD 和6MWT 比较差异无显著性（P ＞0．05），治疗后2组上述指标均显著性升高（P ＜0．05和 P ＜0．01），但治疗后上述指标在观察组显著高于对照组（P ＜0．05）。观察组临床治疗有效率为90．0％显著优于对照组的75．0％（P ＜0．05）。对照组和观察组不良反应发生率分别为7．5％和10．0％，两组之间比较差异无显著性（P ＞0．05）。结论：G-CSF 可以高效动员 EPCs，有利于心梗患者心功能的恢复。%Objective To observe the effect of motivation of endothelial progenitor cells (EPCs) by granulocyte colony-stimulating factor (G-CSF) on cardiac function in patients with myocardial infarction (MI). Methods Eighty MI patients were sellectedand then were divided into a conventional treatment group (n = 40) and a EPC motivation group (n = 40). EPCs were detected by flow cytometry. Results The rate of EPCs was increased from (0.11 ± 0.04)% in the baseline to (5.32 ± 1.06)% (P < 0.05). Before treatment, 6MWT, LVEF, and LVEDD did not differ significantly between the conventional treatment group and the EPC motivation group (P > 0.05); after treatment, 6MWT, LVEF, and LVEDD were significantly increased in both groups (P < 0.05 and P < 0.01). However, 6MWT, LVEF, and LVEDD were higher in the EPC motivation group than in the conventional treatment group (P <0.05). The clinical effectiveness rate was higher in the EPC motivation group than in the conventional treatment group (90.0% vs. 75.0%, P < 0.05). There was no significant difference between the two groups in adverse reactions (7.5%vs. 10.0%, P > 0.05). Conclusions G-CSF can markedly motivate EPCs, which is beneficial for improvement of cardiac function in MI patients.
