| 摘要： |
| 目的: 观察运动训练对血肿周围组织细胞凋亡的影响。方法: 120只SD大鼠被随机分为3组，实验组（40只，出血并运动）、对照组（40只，出血不运动）和假手术组（40只，无出血，不运动），前两组又分为术后24h,7d,14d,21d,28d,5个时相点，每个时相点3只用于TUNEL，5只用于流式细胞仪检测。 结果: TUNEL阳性细胞数在脑出血（ICH）24h时实验组和对照组无区别，但与假手术组相比差异有非常显著性（P<0.01），凋亡于ICH术后7—14d一度下降，21d后回升，28d又下降，但实验组表达明显低于对照组（P<0.05）。凋亡不仅存在于血肿周围组织和皮质，海马区也可见明显凋亡现象。流式细胞分析：不同时间细胞凋亡率的变化趋势与TUNEL 阳性细胞数一致，而且实验组凋亡率明显低于对照组，差异有显著意义（P<0.05）， 但双参数分析较单参数灵敏性更高，差异有非常显著意义（P<0.01）。结论：运动训练可以通过抑制脑出血后血肿周围的神经细胞凋亡，从而改善神经功能。 |

| Abstract: |
| Objective: To investigate the effects of cage-running exercises on apoptosis of neuronal cells surrounding the hematoma in ICH rats. Method: A total of 120 male SD rats were randomly divided into three groups, trial group (ICH with EX n=40), control group( ICH with no EX n=40) and sham operated group (no ICH, no EX n=40). The rats brains were harvested at the 24th h,7th d，14th d，21st d，28th d after ICH. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-bioti in situ nick end-labeling(TUNEL) was used to detect deoxyribonucleic acid(DNA) fragmentation. Flow cytometry assay(FCA) was quantified for DNA. Result: ①TUNEL-positive cells appeared in the periphery of hematoma and hippocampus. The number of TUNEL-positive cells was nearly zero in the sham-operated group, and this number increased markedly in control group from the 14th d to 28th d after ICH, but it reduced in trial group at the same time. Even though, the number of TUNEL-positive cells in two groups once decreased from the 7th—14th d, but the number of TUNEL-positive cells in trial group was less than that in control group. There was a significant difference between two groups（P<0.05）. ②The apoptotic regularity of flow cytometry assay was similar to that of TUNEL-positive cell. But the apoptotic rate of neuronal cells in Annexin Ⅴ-P was more higher than that in PI. Conclusion: Exercises training (cage-running) can inhibit the number of apoptotic cells. |
