人体冷冻争议背后:参与的人至今没有一例复苏

2017-09-01 13:41:13   新华网

该负责人告诉《中国新闻周刊》,复活之路还很漫长,目前用低温技术延长捐献器官的保活时间,更具有社会的现实意义和临床意义。

关于银丰该项目中遗体捐赠的应用方向,也是一个舆论关注的焦点。目前,关于遗体捐献,在国家层面上,中国法律尚未有统一规定,一些省份结合自身情况出台了相应的文件。其中通常会规定,捐献的遗体应当用于医学教育、科研和临床三类。

银丰研究院上述负责人称:“我们的定位是科研,我们的低温保存技术的初衷也是科研。”

但一些业内的专家认为,科研的定义还比较宽泛。广州医科大学卫生管理学院法学系副教授龚波认为,银丰研究院这起中国首例本土人体冷冻,只是一个关于遗体捐献用于医学研究的案例。

银丰研究院上述负责人称,现在已经停止从死囚身上摘除器官的做法,遗体捐献者成为捐献器官唯一来源,而捐献器官有严格的配型要求和时间限制,现在,摘除后的器官一般保存二三十个小时。如今通过低温技术的发展,可以把保存时间延长,形成一个器官银行或器官库的概念。有合适的移植对象后,再进行移植。

“我们现在希望更多人关注低温保存技术,更多的科技工作者参与进来。器官是救命的,民航等对器官的转运开通绿色通道。哪怕是把一个器官的保活时间延长一个小时,也有非凡意义。”

这位负责人同时认为,复活之路还很漫长。

无法兑现的复活期

银丰基金会负责人贾森认为,冷冻人体是低温生物学发展的终极目标。细胞冷冻,下一步就是组织器官,再下一步,就是人体。“人体冷冻只是一种通俗化表达,更为科学的表述,应该是人体低温保存”。

但是,从现实来看,这样的终极目标有些遥不可及。

统计显示,自诞生首次人体冷冻案例(1967年1月19日,美国物理学家贝德福成为世界上第一个被人工冷藏)后,截至2016年底,全球已有300多位被医学上判定为死亡的人参与人体冷冻,但至今没有一例复苏。甚至,在实验室中,目前还没有哪怕是小白鼠等动物身上,取得低温冷冻再复活的成功案例。

桂军民签名的知情同意书中,明确写着:“银丰研究院没有保证、担保或承诺生命延续研究计划在未来一定会成功,也不能准确预测未来医学科技的发展时间表,复苏技术基于未来医学技术的巨大进步。”
