摘要:

背景:国内外大量实验研究证明,不同的运动强度容易造成大鼠肝脏的损伤,从而导致肝细胞凋亡,其具体机制尚不明确。
目的:以期探讨长期不同强度运动对大鼠肝脏细胞形态和功能的影响,为缓解和预防运动性疾病提供一定的理论支撑。
方法:由第一作者应用计算机检索中国期刊全文数据库(CNKI)、PubMed数据库和维普数据库有关有氧运动对肝脏细胞功能影响研究,在标题、摘要、关键词中以“运动强度;肝细胞;细胞凋亡;凋亡检测”或与“exercise intensity;hepatocytes;apoptosis;apoptosis detection”为检索词进行检索。选择与不同强度有氧运动对大鼠肝细胞影响研究有关的文献,且同一领域选择发表于权威杂志的文献。共纳入44篇文献进行分析。
结果与结论:急性力竭运动可使大鼠肝细胞组织结构显著受损。大强度运动因自由基的生成和消除不均衡、肌浆网摄钙能力降低,启动大鼠肝细胞的凋亡,又因负荷量难以把握,因此研究难度较大,需要更多的实验来佐证。中等强度下大鼠的肝脏组织逐渐出现适应性改变,肝细胞的损伤减弱,机体趋向于恢复过程。递增强度和低氧状态下亦对大鼠肝细胞组织和功能产生了不同程度的损伤。结果表明,不同强度的有氧运动会对大鼠肝细胞的结构和功能造成不同程度的影响,提示在训练过程中遵循运动训练学的原则,以此缓解运动性疲劳和预防运动性疾病。

Abstract:

BACKGROUND: A large number of experimental studies have shown that different exercise intensities can easily lead to liver injury in rats, thereby resulting in apoptosis. However, the mechanism is still unclear.
OBJECTIVE: To investigate the effects of different intensity exercise on the morphology and function of rat liver cells in order to provide some theoretical support for alleviating and preventing sports-induced diseases.
METHODS: A computer-based online search of CNKI database, PubMed database and VIP database was performed to search related articles with the keywords of “exercise intensity; hepatocytes; apoptosis; apoptosis detection” in Chinese and English, respectively. The literatures related to the effects of different intensity of aerobic exercise on the liver cells of rats were selected. Articles published in the authoritative journals in the same field were preferred. Totally 44 literatures were analyzed.
RESULTS AND CONCLUSION: Acute exhaustive exercise can damage the liver cells of rats. Large intensity motion initiates rat liver cell apoptosis, due to the imbalance between the formation and elimination of free
 
radicals and the reduced capacity of the calcium uptake by sarcoplasmic reticulum. Because of the difficulty in determination of load capacity, however, it is difficult to study and more experiments are needed. Under moderate intensity exercise, the liver tissues exhibit adaptive changes that the damage is weakened and the body tends to recovery. Increasing intensity of exercise and hypoxia both cause damage to the liver tissue and function in rats. These findings indicate that different intensities of aerobic exercise can lead to changes in the structure and function of rat liver cells to different extents, suggesting that the principle of exercise training should be followed to alleviate exercise fatigue and prevent sports-induced diseases.
