[ti:Prison Sentences for Chinese Scientist Who Changed Babies' Genes][by:shang05.com][00:00.00]更多听力请访问shang05.com[00:00.04]A Chinese court has sentenced the scientist who created[00:04.24]the world's first "gene-edited" babies to three years in prison.[00:11.40]He Jiankui was found guilty of illegally practicing medicine and violating research laws.[00:20.20]China's official Xinhua news agency announced the court's decision Monday.[00:27.68]In November 2018, He Jiankui was working as an associate professor[00:34.08]at Southern University of Science and Technology in Shenzhen.[00:40.00]He announced to the world that he had used gene-editing technology[00:45.20]known as CRISPR-Cas9 to change the genes of twin baby girls.[00:53.00]He claimed to have protected them from getting infected with HIV, the virus that causes AIDS.[01:02.36]The announcement fueled an international debate over the ethics of gene editing.[01:09.60]The identity of the girls has not been released, and it is not clear if the experiment succeeded.[01:18.28]The CRISPR tool has been tested in other places to treat diseases in adults.[01:25.36]But many in the scientific community rejected He's work as medically unnecessary and morally wrong.[01:34.84]That is because the genetic changes could be passed down to future generations.[01:42.32]The United States bans editing embryos except for laboratory research.[01:50.00]In 2018, He Jiankui told the Associated Press that he felt a strong responsibility to make an example.[01:59.96]He said that society would decide whether to permit the practice to go forward.[02:07.04]He disappeared shortly after he announced his research at a conference in Hong Kong 13 months ago.[02:15.72]It appears that government officials detained him,[02:19.60]first in the city of Shenzhen near the border with Hong Kong.[02:24.60]In addition to a prison sentence, the court ordered He Jiankui to pay about $430,000.[02:33.68]The court ordered shorter sentences for Zhang Renli and Qin Jinzhou for having helped He with his work.[02:42.28]They worked at two unnamed medical centers.[02:47.32]Xinhua reported the court's decision as saying:[02:51.08]"The three accused did not have the proper certification to practice medicine,[02:56.80]and in seeking fame and wealth, deliberately violated national regulations[03:03.04]in scientific research and medical treatment."[03:07.80]The decision also said that the researchers "have crossed the bottom line of ethics[03:14.04]in scientific research and medical ethics."[03:18.68]It was not clear if the three-year prison term includes any of the time He has already spent in Chinese detention.[03:28.88]One Chinese scientist said the sentence should have been greater to urge others not to follow in He's work.[03:38.80]Kehkooi Kee is a Tsinghua University researcher who does gene-editing research on stem cells.[03:47.48]Kehkooi Kee said He Jiankui should be held responsible[03:50.72]for anything that happens to the babies or their families as a result of the experiment.[03:58.80]William Hurlbut is a Stanford University bioethicist[04:02.92]whose advice He sought for more than a year before his experiment.[04:08.48]Hurlbut said he felt sorry for the scientist, his wife and two young daughters.[04:16.20]"I warned him things could end this way, but it was just too late,"[04:21.12]Hurlbut wrote in an email to the Associated Press.[04:25.96]He added, "Sad story — everyone lost in this...but the one gain is that the world[04:33.12]is awakened to the seriousness of our advancing genetic technologies."[04:39.76]I'm Jonathan Evans. 更多听力请访问shang05.com
