我是一个退休教师,步入老境后,因体质原本较弱,加上深居简出,双腿的肌肉开始萎缩。行动不便,苦不堪言。随着老境的到来,哺乳动物的一个显著变化是:During the aging process,mammals lose up to a third of their skeletalmuscle mass and strength.今天,我从因特网上读到一篇文章,非常兴奋。一种基 因疗法(gene therapy)在老鼠身上的实验已经获得成功,这种疗法能减缓衰老:itmay be possible to preserve muscle size and strength in old age using thisapproach.将这种基因注入人体的方法耐人寻味。基因疗法的前景非常诱人:Thebeneficial effects of this gene therapy could easily be used by humans for athleticor even cosmetic enhancements.到了下世纪的中叶,也许,人的外貌将具有极大的迷惑性,人之外貌将很难成为人的年龄的“凭证”！虽然,我活不到那个时候,但是,想到未来科学的进展,我的心头仍洋溢着快慰和欣喜。】 I am a retired teacher. After entering the old world, the physical quality of the body is relatively weak, and the deep muscles of the two legs have begun to shrink. Inconvenient actions, miserable. With the advent of old times, a significant change in mammals is: During the aging process, mammals lose up to a third of their skeletal muscle mass and strength. Today, I read an article from the Internet, very excited. A study of gene therapy in rats has been successful. This therapy can slow down aging: itmay be possible to preserve muscle size and strength in old age using this approach. The method of injecting this gene into the human body is intriguing. The prospect of gene therapy is very attractive: Thebeneficial effects of this gene therapy could easily be used by humans for athleticor even cosmetic enhancements. By the middle of the next century, perhaps, people’s appearance will be extremely confusing and people’s appearance will be very It is difficult to become the “voucher” for people’s age! Although, I could not live until that time, but my mind is still filled with soothing joy and joy when I think of the progress of science in the future. 】
