This paper aimed to determine whether the brain structure of the people who practice long-term Tai Chi exercises differs from that of their sedentary counterparts,and whether the difference is associated with exercise duration and skill level.Diffusion tensor imaging and whole-brain voxel-based analysis(VBA)were used in this study.The volunteer-participants were 20 older Tai Chi practitioners and 25 age-,gender-,health-,and fitness condition-matched sedentary people.The mean exercise duration of the Tai Chi group was 8.45 years.A medical examination confirmed that all of the participants were qualified to undergo MRI scanning.The imaging graphs were processed using whole-brain VBA to identify differences in brain volume.The volumes of interest were analyzed further to determine the between-group differences in isotropic fraction(FA)and apparent diffusion coefficient(ADC).The rank correlation analysis was performed for FA and ADC according to the exercise duration and skill level.Results of the VBA analysis indicated that the exercise group had higher FA in splenium corporis callosi(0.86 0.04 vs.0.84 0.02,P < 0.05)and higher ADC value(0.78 0.05 vs.0.74 0.05,P < 0.05)than the control group.In the exercise group,the FA value of splenium of corpus callosum was moderately related to the exercise duration(r = 0.45, p = 0.045),but highly related to the skill level(r = 0.699,p < 0.01).We concluded that Tai Chi exercise could change the cerebral white matter fiber,which had a correlation with the exercise duration and skill level.Therefore,the long-term and skillful exercise of Tai Chi would delay the brain volume atrophy,which could be the central basis for the improved balance capacity of Tai Chi practitioners.

肿瘤发生(tumorigenesis)是正常细胞在各种压力的刺激下发生诸多基因和表观遗传的变异,逐渐形成癌细胞并最终发展为肿瘤的过程.这一过程涉及到许多细胞内在机制的变化,以及细胞与周围微环境联系的改变.加深对该过程的了解,对于预防肿瘤的发生以及再发或复发具有重要意义.众多研究表明,自噬不仅在这一过程中发挥重要作用,而且还表现出抑癌和促癌的双重性.研究表明,自噬在肿瘤发生的整个阶段,始终起着保护细
