文题释义:
肌肉卫星细胞:骨骼肌中除骨骼肌纤维(肌细胞)外的一种扁平、有突起的细胞,附着于肌纤维(肌细胞)表面。当肌纤维(肌细胞)受损后,肌卫星细胞可增殖分化,参与肌纤维(肌细胞)的修复,因此具有干细胞性质。
骨骼肌减少症:是衰老过程中肌肉质量、力量下降和机能能力丧失的退行性改变,发生的根本原因为神经-肌肉功能减退。


 

背景:随着年龄增长,人体会出现肌肉萎缩或肌减少症现象,结果引起肌肉功能的退行性改变,运动训练有利于人体肌肉质量和改善肌肉功能,在这个过程中肌卫星细胞起着关键的作用。
目的:总结卫星细胞在调节骨骼肌质量方面的作用机制、与衰老相关的肌肉质量和力量下降过程中肌纤维卫星细胞变化、运动干预减弱和扭转效果、目前研究现状和不足以及未来的研究方向。
方法:检索PubMed 数据库相关文章,检索时间为1986至2015 年,检索词为“sarcopenia,skeletal muscle,satellite cells”,并限定文章语言种类为英语,再从中筛选出与主题相关的部分文献,进行总结分析讨论。
结果与结论:初检得到168篇文章,按主题相关性对文献进一步筛选,最终纳入39篇文章。骨骼肌减少症表现为Ⅱ型肌纤维萎缩,并且出现Ⅱ型肌纤维卫星细胞含量同步减少。运动有利增加老年人肌肉质量和改善肌肉功能。抗阻和耐力2种运动训练方式都可以增加骨骼肌特别是 Ⅱ肌纤维卫星细胞含量,同时伴随卫星细胞活化和增殖因子的进一步增加。卫星细胞数量及其活化程度都显示与肌肉老化相关,卫星细胞与增殖因子共同调节肌细胞生成。因此,未来研究不仅应侧重于增加卫星细胞库,而且还应探讨促进卫星细胞活化的有效方法(如运动训练、营养和药物)。

Abstract:

BACKGROUND: The phenomenon of atrophy or reduction of muscle, causing degenerative changes of muscle functions, appears along with age. Sports training, in which muscle satellite cells are of great importance, is beneficial to increase in muscle mass and improvement of muscle function. 
OBJECTIVE: To summarize regulatory mechanism of satellite cells in skeletal muscle mass; changes of satellite muscle cells in the degenerative process of muscle mass and strength; declining and reverse effects of sports training intervention; situations and problems of current research and prospective of the future. 
METHODS: A computer-based online search was conducted in PubMed database by using the key words of “sarcopenia, skeletal muscle, satellite cells” from 1986 to 2015. The language was limited to English. The eligible papers were further analyzed and reviewed.
RESULTS AND CONCLUSION: A total of 168 papers were screened. Finally, 39 papers were selected according to the titles and objectives. Skeletal muscle atrophy is shown as II type muscle fiber atrophy, and the II type muscle fiber satellite cell content decreases simultaneously. Exercise is beneficial to increase muscle mass and improve muscle function in older people. Both resistance and endurance trainings can increase the skeletal muscle, especially the II muscle fiber satellite cell content with a further increase in the satellite cell activation and proliferation. The number and activation degree of satellite cells are related to muscle aging, and satellite cells and proliferation factors regulate muscle cell formation. Therefore, future researches should not only focus on the increase of satellite cell bank, but also explore effective ways to promote the activation of satellite cells, such as exercise training, nutrition and drugs.
