摘要:

背景:运动性心肌细胞凋亡及其信号转导和调节机制的研究已成为运动医学领域的重要课题,但其研究成果并未能成功的解释此种现象。从现有的研究成果来看,引入骨髓间充质干细胞对运动性心肌细胞凋亡保护作用的研究还较少。

目的:通过骨髓间充质干细胞对心肌细胞凋亡的保护作用以及运动引起心肌细胞凋亡现象的分析,探讨运动引起心肌细胞凋亡的病理病因,及骨髓间充质干细胞对保护机体心肌细胞因运动致使缺氧、缺血、氧化应激等诱导细胞凋亡的作用。

方法:应用计算机检索Medline数据库(1994-01/2009-09),以Mesenchymal stem cells,Excessive exercise,Cardiomyocyte,Apoptosis为检索词;应用计算机检索重庆维普数据库(1994-01/2009-09)、清华同方数据库(1994-01/2009-06),以骨髓间充质干细胞、过度训练、心肌细胞、细胞凋亡为检索词。

结果与结论:共收集365篇关于干细胞和运动性心肌细胞凋亡的文献,中文120篇,英文245篇。排除发表时间较早、重复及类似研究,纳入68篇符合标准的文献。骨髓间充质干细胞对大强度或超负荷的运动训练所引起的缺氧、缺血、氧化应激等诱导的心肌细胞凋亡有保护作用,从而促进心脏功能的提高和运动性心肌组织疾病的早期康复。

Abstract:

BACKGROUND: Exercise-induced myocardial cell apoptosis and signal transduction and regulation mechanisms of sports medicine research have become an important issue, but remain poorly understood. Studies concerning the protective effect of bone marrow-derived mesenchymal stem cells (MSCs) to the exercise-induced myocardial cell apoptosis are rarely conducted.

OBJECTIVE: To analyze the protective effect of MSCs on myocardial apoptosis and the exercise-induced myocardial cell apoptosis, so as to explore the pathological cause of exercise-induced myocardial apoptosis and the protective effects of MSCs on myocardial cell apoptosis induced by hypoxia, ischemia, and oxidative stress.

METHODS: A computer-based online search of articles was performed in Medline database (1994-01/2009-09) with “Mesenchymal stem cells, Excessive exercise, Cardiomyocyte, Apoptosis” as key words and Chongqing PubMed Result NCBI database (1994-01/2009-09), Tsinghua Tong Fang database (1994-01/2009-06), with “bone marrow mesenchymal stem cells, over-training, myocardial cells, apoptosis” as key words.

RESULTS AND CONCLUSION: A total of 365 articles on stem cells and exercise-induced myocardial apoptosis were collected, including 120 Chinese and 245 English. Outdate, repetitive and similar studies were excluded, and 68 were included. MSCs display a protection to myocardial cell apoptosis induced by hypoxia, ischemia and oxidative stress caused by high-intensity or overload exercise training, thereby contributing to the improvement of heart function and early rehabilitation of exercise-induced myocardial tissue diseases.
