日本首次利用iPS细胞治疗人类帕金森病

日本京都大学9日宣布,该校研究人员已经开展了利用诱导多能干细胞(iPS细胞)治疗帕金森病的临床试验,向一名患者脑部移植了由iPS细胞培养的神经祖细胞。这种疗法在全球尚属首次使用。



京都大学医学部附属医院9日在记者会上介绍了这例移植手术。手术于今年10月完成,患者是一名50多岁的男性,被移植的是由他人iPS细胞培养的多巴胺神经祖细胞。在约3小时的移植手术中,医生向这名患者脑部注入了约240万个多巴胺神经祖细胞。

据介绍,这是全球首例利用iPS细胞治疗人类帕金森病的移植手术,目前患者恢复情况良好,手术效果和安全性还需长期观察。按计划,这次开展的临床试验将为7名患者进行移植。



iPS细胞是通过对成熟体细胞“重新编程”培育出的干细胞,拥有与胚胎干细胞相似的分化潜力。此前研究人员曾在动物研究中证实,iPS细胞疗法能够治疗猴子的帕金森病。

帕金森病是一种神经系统变性疾病,主要病理改变是脑部分泌多巴胺的神经细胞死亡,临床表现包括手脚震颤、身体僵硬、行动迟缓等,目前尚无根治方法。

我们为什么不能推广“日本看病模式”?

近年来,网上反复流传一篇《亲历日本搭桥手术》的文章,内容是作家王石讲述他在日本神原纪念医院就医的经历:第一次去没事先预约,预约好第二次赴日,两天一夜完成七项检查,检查项目包括不必切开的冠脉造影、量血压分别测量四肢,而抽血后观察5分钟敷料24小时、跪式服务的护士、精致美味的餐点、和饭店一样临走再收费这些细节给了他很深印象。该文总是被人翻出来,可能有把作家王石当成企业家王石的原因,但另一方面,也有中国

日本版《好医生》:放弃了自闭,营造了治愈

山崎贤人、上野树里、藤木直人主演的日本富士电视台木十档电视剧《好医生》开播收视率超过百分之十,人气小生山崎贤人对收视率的贡献功不可没,电视剧本身也散发着日式的温和。但横向对比起来,就显得偏弱。日本富士电视台版本的《好医生》改编自2013年周元主演的同名韩剧,故事的男主角新堂凑(山崎贤人饰)是一个附带“学者综合症”的自闭症患者,尽管他能够生活自理,能够进行日常交流,记忆力和学习能力超群,对空间感知能
