ABSTRACT
it was to explore effect of isosorbide dinitrate combined with exercise training and rehabilitation on endothelial progenitor cells (EPCs) in coronary heart disease. EPCs were isolated and cultured from peripheral blood of coronary heart disease patients, and morphology and surface markers were detected. Then, 116 patients were rolled into treatment group (isosorbide dinitrate + exercise rehabilitation training) and control group (isosorbide dinitrate). Characteristics of EPCs cells after treatment were compared. The mononuclear cells were round and small in size and were not evenly distributed in the culture plate. EPCs cells grew as colonies after 8d-culture, and the surrounding cells grew outward in a germinating manner with colonies as the center, forming multiple cell populations. Positive rates of EPCs surface markers CD133, CD34, and vascular endothelial growth factor receptor (KDR) were 11.25 ± 3.07%, 48.18 ± 9.13%, and 76.36 ± 8.27%, respectively. Proliferation activity of EPCs in the treatment group was dramatically higher versus controls at day three, five, and seven (P < 0.05). Adhesion ability of EPCs in treatment group was dramatically higher than controls at day three, five, and seven (P < 0.05). Migration ability of EPCs in treatment group was dramatically higher versus control group at day three, five, and seven (P < 0.05). In short, isosorbide dinitrate plus exercise rehabilitation greatly enhanced the proliferation activity, adhesion ability, and migration ability of EPCs cells, which also played a beneficial role in the repair of endothelial injury, with notable effects.
