Nicholas Burns was sworn in as the new US ambassador to China on Tuesday, Deputy Secretary of State Wendy Sherman said on her Twitter account.

双语热点:人类首次成功接受猪心脏移植,患者术后状况良好******

一位现年 57 岁的心脏病患者上周五接受转基因猪心脏移植手术,术后病人情况良好。这也是人类首次成功将转基因猪心脏移植到患者体内,有望为心脏病患者带来希望。

In a First, Man Receives a Heart From a Genetically Altered Pig

A 57-year-old man with life-threatening heart disease has received a heart from a genetically modified pig, a groundbreaking procedure that offers hope to hundreds of thousands of patients with failing organs.

一名因患心脏病有生命危险的57岁男子移植了来自一只经过基因改造的猪的心脏,这项开创性的手术为数十万器官衰竭的患者带来了希望。

It is the first successful transplant of a pig’s heart into a human being. The eight-hour operation took place in Baltimore on Friday, and the patient, David Bennett Sr. of Maryland, was doing well on Monday, according to surgeons at the University of Maryland Medical Center.

这是第一次成功地将猪的心脏移植到人体内。据马里兰大学医学中心的外科医生称,这项耗时8小时的手术于周五在巴尔的摩进行,来自马里兰州的患者老戴维·贝内特周一状况良好。

“It creates the pulse, it creates the pressure, it is his heart,” said Dr. Bartley Griffith, the director of the cardiac transplant program at the medical center, who performed the operation.

“它能产生脉搏,产生血压,成为了他的心脏,”执行手术的医疗中心心脏移植项目主任巴特利·格里菲斯博士说。

“It’s working and it looks normal. We are thrilled, but we don’t know what tomorrow will bring us. This has never been done before.”

“它正在跳动,看起来很正常。我们都很兴奋,但我们不知道接下来会怎样。这是前所未有的。”

Last year, some 41,354 Americans received a transplanted organ, more than half of them receiving kidneys, according to the United Network for Organ Sharing, a nonprofit that coordinates the nation’s organ procurement efforts.

根据协调美国器官采购工作的非营利组织器官共享联合网络(United Network for Organ Sharing)的数据,去年约有41354名美国人接受了移植器官,其中一半以上是肾脏。

But there is an acute shortage of organs, and about a dozen people on the lists die each day. Some 3,817 Americans received human donor hearts last year as replacements, more than ever before, but the potential demand is still higher.

但器官严重短缺,名单上平均每天约有十多人死亡。去年有3817名美国人接受了捐赠心脏移植,该数字高过以往任何时候,但潜在需求仍然更高。

Scientists have worked feverishly to develop pigs whose organs would not be rejected by the human body, research accelerated in the past decade by new gene editing and cloning technologies. The heart transplant comes just months after surgeons in New York successfully attached the kidney of a genetically engineered pig to a brain-dead person.

科学家们一直在努力培育器官不会在人体内产生排斥反应的猪,过去10年中,新的基因编辑和克隆技术加速了研究。在这次心脏移植手术的几个月前,纽约的外科医生成功地将一头基因改造猪的肾脏移植到一个脑死亡的人体内。

Researchers hope procedures like this will usher in a new era in medicine in the future when replacement organs are no longer in short supply for the more than half a million Americans who are waiting for kidneys and other organs.

研究人员希望这样的手术将在未来开启医学的一个新时代,届时超过50万正在等待肾脏和其他器官的美国人所需的替代器官将不再短缺。

“This is a watershed event,” said Dr. David Klassen, the chief medical officer of the United Network for Organ Sharing and a transplant physician. “Doors are starting to open that will lead, I believe, to major changes in how we treat organ failure.”

“这是一个分水岭事件,”器官共享联合网络的首席医疗官兼器官移植医师大卫·克拉森博士说。“我相信,机会的大门正在打开,这将使我们治疗器官衰竭的方式发生重大变化。”

But he added that there were many hurdles to overcome before such a procedure could be broadly applied, noting that rejection of organs occurs even when a well-matched human donor kidney is transplanted.

但他还说,在这种手术可以广泛应用之前,还有许多障碍需要克服,并指出器官排斥反应即使在移植了匹配良好的人类供体肾脏后也会发生。

“Events like these can be dramatized in the press, and it’s important to maintain perspective,” Dr. Klassen said. “It takes a long time to mature a therapy like this.”

“像这样的事件在媒体上可能被夸大,保持客观很重要,”克拉森博士说。“这样的治疗需要很长时间才能成熟。”

Mr. Bennett decided to gamble on the experimental treatment because he would have died without a new heart, had exhausted other treatments and was too sick to qualify for a human donor heart, family members and doctors said.

家人和医生说,由于贝内特已经用尽了其他治疗方法,如果没有新的心脏,他就会死亡,而且他病得太重,不符合获得人类捐赠的心脏的资格,于是决定赌一把,进行实验性治疗。

His prognosis is uncertain. Mr. Bennett is still connected to a heart-lung bypass machine, which was keeping him alive before the operation, but that is not unusual for a new heart transplant recipient, experts said.

他的预后尚不确定。专家说,贝内特仍然连接着一台心肺搭桥机,这台机器在手术前维持他的生命,但这对于心脏移植接受者来说并不罕见。

The new heart is functioning and already doing most of the work, and his doctors said he could be taken off the machine on Tuesday. Mr. Bennett is being closely monitored for signs that his body is rejecting the new organ, but the first 48 hours, which are critical, passed without incident.

新的心脏正在运作并且已经自主完成了大部分工作,他的医生说他有可能在周二离开机器。贝内特正在密切监测他的身体是否有排斥新器官的迹象,但至关重要的前48小时没有发生任何事故。

Xenotransplantation, the process of grafting or transplanting organs or tissues from animals to humans, has a long history. Efforts to use the blood and skin of animals go back hundreds of years.

异种移植——从动物身上移植或移植器官或组织给人类的过程——由来已久。使用动物血液和皮肤的尝试可以追溯到数百年前。

In the 1960s, chimpanzee kidneys were transplanted into some human patients, but the longest a recipient lived was nine months. In 1983, a baboon heart was transplanted into an infant known as Baby Fae, but she died 20 days later.

在20世纪60年代,黑猩猩的肾脏被移植到一些人类患者体内,但接受者最长存活了9个月。1983年,一颗狒狒的心脏被移植到一个名为菲宝宝的婴儿体内,但她在20天后死亡。

Pigs offer advantages over primates for organ procurements, because they are easier to raise and achieve adult human size in six months. Pig heart valves are routinely transplanted into humans, and some patients with diabetes have received porcine pancreas cells. Pig skin has also been used as a temporary graft for burn patients.

相较于灵长类动物,猪在器官供源上有优势,因为猪更易于培育,可以在六个月内达到成年人类器官的大小。人类移植猪心瓣膜已经很常见,一些糖尿病患者接受了猪胰腺细胞移植。猪的皮肤会用于烧伤患者的暂时性植皮。

Two newer technologies — gene editing and cloning — have yielded genetically altered pig organs less likely to be rejected by humans. Pig hearts have been transplanted successfully into baboons by Dr. Muhammad Mohiuddin, a professor of surgery at University of Maryland School of Medicine who established the cardiac xenotransplantation program with Dr. Griffith and is its scientific director. But safety concerns and fear of setting off a dangerous immune response that can be life-threatening precluded their use in humans until recently.

利用两项较新的技术——基因编辑和克隆——可以获得经过基因改造的猪器官,降低被人体排斥的几率。马里兰大学医学院外科教授穆罕默德·莫修丁博士曾成功将猪心脏移植到狒狒体内,莫修丁与格里菲斯共同创办了异种心脏移植项目,并任科学总监。由于安全方面的担忧,加之害怕导致可能危及生命的危险免疫反应,这些技术直到最近才开始应用到人体上。

Dr. Jay Fishman, the associate director of the transplantation center at Massachusetts General Hospital, said that using pig organs provides the ability to perform genetic manipulations, the time to carry out better screening for infectious diseases, and the possibility of a new organ at the time that the patient needs it.

麻省总医院移植中心助理主任杰·费希曼博士说,使用猪器官意味着可以进行基因控制,可以有更多的时间进行传染病筛查,还可以根据病人的需要决定进行移植的时间。

“There are challenges for sure, but also opportunities,” he said.

“这些当然都是挑战,但也是机会,”他说。

The heart transplanted into Mr. Bennett came from a genetically altered pig provided by Revivicor, a regenerative medicine company based in Blacksburg, Va.

贝内特的移植所用到的基因改造猪由弗吉尼亚州布莱克斯堡再生医学公司Revivicor提供。

The pig had 10 genetic modifications. Four genes were knocked out, or inactivated, including one that encodes a molecule that causes an aggressive human rejection response.

这只猪进行了10处基因修改。四个基因被剔除或失活,其中一个携带了一种可导致剧烈人体排斥反应的分子的编码。

A growth gene was also inactivated to prevent the pig’s heart from continuing to grow after it was implanted, said Dr. Mohiuddin,who, with Dr. Griffith, did much of the research leading up to the transplant.

莫修丁说,一个生长基因也被失活,以防止猪心脏在移植后继续生长,此次移植的相当一部分研究工作是由他和格里菲斯进行的。

In addition, six human genes were inserted into the genome of the donor pig — modifications designed to make the porcine organs more tolerable to the human immune system.

此外在供体猪的基因组内还插入了四个人类基因——这一修改的目的是让猪器官更能适应人类免疫系统。

RNG频繁与娱乐圈互动遭真爱粉吐槽,没有粉丝RNG就是联赛垫底!******

原标题:RNG频繁与娱乐圈互动遭真爱粉吐槽,没有粉丝RNG就是联赛垫底!

众所周知电子竞技战队的目的其实就是为了盈利,而要实现盈利势必要开展一些商业活动,已经多多宣传增加影响力,而最近RNG校园行就被爆出在浙江大学吃了闭门羹,但不可否认RNG确实把电子竞技带进了很多高校,想必RNG为此也花费了不少钱,近日吴磊粉RNG的微博可以说得到了很多RNG粉丝额重视,RNG更是与其频繁互动!

但是这个举动确实让很多粉丝很是不开心,不得不说最近RNG节奏确实很多,RNG现在也没有比赛可打,但是节奏频发确实值得俱乐部注意,很多粉丝吐槽现在RNG应该悄悄提高自己的实力,不应该过度张扬,频繁与娱乐圈明星互动,确实有点不务正业的感觉!

其实RNG此举也不过是增加RNG的影响力,虽说现在RNG没有比赛可打,但是人员配置依旧没有进展,当初和RNG接触的狼行也被王思聪搅黄了,下一步RNG该怎么解决人员问题依旧没有定数,Letme与MLXG是否回归也没有答案!

不得不说也只有真爱粉会这么替RNG考虑了,其实SciSci酱很看中一位RNG粉丝所说的话,那就是RNG没有这些粉丝的话,早就LPL垫底了,就好比SDG虽说同样也是止步季后赛,但因为战队粉丝基数不多,其实成绩和LPL垫底没有差别,RNG现在就只剩下粉丝了!

最大规模“环太军演”?金一南:这是最不平等的国际秩序!

1.新华网XR看报告:走心“绘景”,展现美好“愿景”

2.“做文明互鉴的促进者和人民友好的传承者”

3.外媒继续关注我新型舰载机:光洁的令人难以置信

4.王艳北京郊区农场曝光!种满各种蔬菜院子价值非凡
