胎儿确诊为重型地贫一定要终止妊娠。地贫属于容易预防很难根治的遗传性疾病,轻型的地贫往往不需要终止妊娠,轻型地贫患儿和正常婴儿几乎无异但是需要平时注意一下饮食营养均衡,如果胎儿确诊为重型地贫必须要终止妊娠。

重症患儿需要进行造血干细胞移植胎儿就必须长期依靠输血并终身服用除铁挤维持生命,即使如此胎儿的存活率依然不高,随着年龄的增长身体的发育,胎儿的地贫症状会越来越严重,铁长期的沉积在肝脾等器官最终引起器官衰竭导致死亡。所以在结婚之前一定要了解自己家族的遗传病,产前做好筛查,如果胎儿确诊为重型地贫一定要终止妊娠。

九月份备孕去做地筛医生说是怀疑是地贫,进一步检查抽血基因测序然后检查结果HbA是95.2,HbA2是2.6,HbF1.9先请问一下姐妹们这个有可能是地贫吗?下周就会出结果了,已经怀孕一个月了需要终止妊娠吗?

轻度地贫是可以放心的怀孕的,生的孩子有一半的几率都是健康的或者是轻度地贫,轻度地贫对胎儿后期的发育和生活是没有什么影响的,只要在孕期做好检查就好了,避免是先天携带重度地贫,轻度地贫可以不终止妊娠。

如果是地贫要怀孕的话一定要做好检查哦,我有个朋友的女儿就是地贫,现在每个月都要去医院输血,而且每天都要吃除铁药,除了经济上的负担还有精神上的压力,稍微一停药就有可能有生命危险。

你这个各项数据都有点偏高,患轻度地贫的概率有一点高哦,你可以查一下你们家族里面有没有人是地贫,如果有你这个情况大概率就是地贫,不是普通的缺铁性贫血。

如果有一天,你可以选择生育一个小“爱因斯坦”,也可以生育一个智商普通的孩子,你会做出什么样的选择?据科学家预计,未来10年内,人类将可以使用试管婴儿技术选择“最聪明”的胚胎。

Couples undergoing IVF treatment could be given the option to pick the “smartest” embryo within the next 10 years, a leading US scientist has predicted.

据美国一名权威科学家预计,未来10年之内,做试管婴儿的夫妇将能够选择“最聪明”的胚胎。

Stephen Hsu, senior vice president for research at Michigan State University, said scientific advances mean it will soon be feasible to reliably rank embryos according to potential IQ, posing profound ethical questions for society about whether or not the technology should be adopted.

美国密歇根州立大学主管科研的副校长徐道辉(斯蒂芬·徐)说,科学进步意味着人类不久就能够对胚胎的潜在智商给出可靠的评分,这项技术是否应该使用将是一个深刻的社会伦理问题。

Hsu’s company, Genomic Prediction, already offers a test aimed at screening out embryos with abnormally low IQ to couples being treated at fertility clinics in the US.

徐道辉的基因组预测公司已经为在美国不孕不育诊所接受治疗的夫妇提供了一项检测服务,旨在筛查出智商异常低的胚胎。

“Accurate IQ predictors will be possible, if not the next five years, the next 10 years certainly,” Hsu told the Guardian. “I predict certain countries will adopt them.”

徐道辉对《卫报》记者说:“准确的智商预测是可能的,即使不是未来5年内,那么在未来10年内也肯定可以。我预计一些国家会采纳这项技术。”

The prospect of a new generation of genetically selected babies has prompted concerns about unintended medical consequences and the potential for deepening existing social inequalities. The science underpinning the claim that intelligence can be meaningfully predicted by genetic tests is also contentious.

新一代基因选择婴儿的前景引发了人们对于意外医疗后果和现有社会不平等可能加剧的担忧。基因检测能够有效预测智商的科学技术也引发了争议。

contentious [kn'tens]:adj.有异议的,引起争论的

Peter Donnelly, a professor of statistical science at the University of Oxford, said any such IQ predictions should be treated with “huge caution”, adding: “I have grave misgivings about it on ethical grounds. I think it’s a really bad idea.”

牛津大学统计学教授彼得·唐纳利说,应该“十分谨慎”地对待此类智商预测。他说:“出于伦理原因,我对此非常担忧。我认为这是一个非常糟糕的想法。”

Since the 1990s, couples undergoing IVF have been able to screen their embryos for mutations in single genes that cause serious diseases such as cystic fibrosis, as well as conditions like Down’s syndrome, caused by chromosome abnormalities.

自上世纪90年代以来,接受试管受精的夫妇已经能够对他们的胚胎进行筛选,以发现单个基因的突变,这些突变会导致严重的疾病,比如囊性纤维化,以及染色体异常导致的唐氏综合征等。

chromosome ['krmsm]:n.染色体

Many other traits, including height, physical appearance, intelligence and disease susceptibility, are known to be partly heritable. But because the genetic component is spread thinly over hundreds or even thousands of DNA regions, it has previously been impossible to screen for these traits.

许多其他特征,包括身高、外貌、智力和疾病易感性,都被认为是部分遗传的。但由于遗传组分稀疏地分散在数百甚至数千个DNA区域,以前不可能对这些特征进行筛选。

In the past decade, as vast genetic databases have been established, this picture has changed. Through analyzing many genes, each making a tiny contribution, it has been possible to calculate what are called polygenic risk scores, which give a person’s likelihood of getting a particular disease or having a certain trait.

在过去的十年里,随着大量基因数据库的建立,这种情况已经发生了改变。通过分析大量基因,每个基因都做出了微小的贡献,就有可能计算出所谓的多基因风险评分,即一个人患某种特定疾病或具有某种特征的可能性。

polygenic[,pli'denik]:adj.多基因的

Genomic Prediction is the first company to take embryo screening into this grey area of risk forecasting, offering to alert couples if an embryo has an “outlier” score for risk of cancers, diabetes, heart disease, dwarfism or low IQ.

基因组预测公司是第一家将胚胎筛查纳入风险预测这一灰色地带的公司。如果胚胎在癌症、糖尿病、心脏病、侏儒症或智商低下等风险方面的评分“异常”,它就会提醒做筛查的夫妇。

outlier ['atla]:n.(统计)异常值

Prediction for IQ is not good enough to give a reliable ranking, but Hsu said that knowing an embryo has a low score could still be desirable.

智商预测目前还不足以给出可靠的评分,但徐道辉表示,如果一个胚胎的智商评分较低,人们可能还是很想知道。

“Maybe the bottom 1% embryo will grow up to be a great person … even be a scientist, but the odds are against it,” he said. “I honestly feel if we can calculate that score and find a real negative outlier there’s an ethical responsibility for us to report that.”

徐道辉说:“也许评分最低的1%的胚胎长大后会成为一个优秀的人……甚至成为一名科学家,但这种可能性很小。我真的觉得,如果我们能计算出这个评分,发现它低得十分异常,那么我们就有道德责任予以告知。”

The company projects that once high-quality genetic and academic achievement data from a million individuals becomes available, expected to be within five to 10 years, it will be able to predict IQ to within about 10 points.

该公司预计,在5至10年内,一旦100万人的高质量基因和学术成就数据可用,它将能够预测智商,误差在10分以内。

Hsu is reticent about whether screening for high intelligence would be ethically justified, saying: “Let me just decline to answer that at the moment.”

徐道辉不愿评论高智商筛查是否符合伦理标准,说“目前我拒绝回答这个问题”。

reticent ['rets()nt]:adj.沉默的;有保留的

In some countries, such as Singapore, there is likely to be a high level of public acceptance and demand for such tests, he suggested. “I think the overwhelming majority would say yes, absolutely, parents should be allowed to do that,” he said. “Before you write your piece, you might just want to think that a billion people on the other side of the world might have a different view.”

徐道辉说,在一些国家,比如新加坡,公众对此类检测的接受度和需求可能会很高。他说:“我认为绝大多数人肯定会赞成允许父母这样做。在你写这篇报道之前,也许应该想想地球另外一端的10亿人可能有不同的看法。”

Whether such tests will become available in the UK would depend on approval from the Human Fertilization and Embryology Authority (HFEA).

这种检测方法能否在英国实施将取决于英国人工授精与胚胎学管理局的批准。

“If the HFEA decides that it’s not right for the UK, I will respect that,” Hsu said, but predicted that “rich people from the UK will fly to Singapore” if they are unable to get the tests locally.

他说:“如果英国人工授精与胚胎学管理局认为这对英国不合适,我会尊重这个决定。”但他预测,如果英国富人无法在当地进行这项检测,“他们会飞到新加坡去做的。”

Some in the UK take the view that prospective parents have a right to access such tests. “I don’t think people should be deprived of that knowledge,” said Prof Simon Fishel, the founder of Care Fertility.

在英国,一些人认为未来的父母有权进行此类检测。生育关怀组织的创始人西蒙费舍尔教授说:“我认为不应该剥夺人们的这种知情权。”

Fishel questioned whether there is any ethical difference between picking an embryo ranked highest for IQ or sending a child to a private school. “What’s wrong with ranking an embryo if you can rank a child?” he said. “I think there are plenty of people who’d choose embryo Oxford [rather] than embryo A-level failure.”

费舍尔质疑挑选智商最高的胚胎和送孩子去私立学校之间是否存在伦理上的差异。“如果你能给孩子评分,那给胚胎评分又有什么错呢?”他说。“我认为有很多人会选择未来能考取牛津的胚胎而不是无法通过英国中学高级水平考试的胚胎。”

In practice, though, couples often have only a few embryos to choose from. And there are concerns about unintended consequences. For instance, there is some evidence linking higher polygenic scores for academic ability to higher likelihood of autism.

但实际上,夫妇们通常只有几个胚胎可供选择。此外,人们还担心会出现意想不到的后果。例如,有证据表明,学术能力的多基因得分越高,患自闭症的可能性就越大。

The technology is controversial, but that does not mean it will not gain acceptance in the future, Hsu said, drawing parallels with the reaction to IVF in its early days.

徐道辉说,这项技术存在争议,但这并不意味着它在未来不会被接受,这与早期人们对体外受精的反应类似。

“The IVF pioneers … were called monsters, Frankenstein doctors; it was predicted that these babies would have health problems,” he said. “I am actually reassured by that. IVF is completely normalized now. Everyone who is pointing their finger at [Genomic Prediction] now should go back and read those articles.”

他说:“试管婴儿的先驱被称为怪物,弗兰肯斯坦医生。当时人们预测这些婴儿会有健康问题。实际上,我对此很放心。试管受精现在已经完全正常化。现在,所有指责(基因组预测)的人都应该回去读读那些文章。”

安医大一附院的三代试管技术可以帮助患者移植两个胚胎,不过最后能不能成功怀双胞胎要看胚胎在子宫内的发育情况。安医大一附院试管婴儿成功率还是挺高的,其中三代试管的成功率可以达到55%左右,所以移植两个胚胎成功的概率也是不错的。但是在安医大一附院移植单胚或者双胚,需要根据患者的身体条件看来决定。

安医大一附院在2003年开展辅助生殖技术以来,有不少患者在第三代试管婴儿技术的帮助下移植两个胚胎最后生下了双胞胎。虽然该院的多胎试管婴儿在技术上来说是不太困难的,但是人类的分娩生育是单胎生育,如果是双胞胎,就是超负荷怀孕,会产生一定的危险。下面是安医大一附院做三代试管不能移植两个生双胞胎的患者情况:

1.患者年龄在35岁以下而且是第一次做试管,如果已经通过三代试管技术筛选出优质的3个胚胎,而且子宫环境适合胚胎着床时,试管成功率是很高的,一般不建议移植两个,避免出现因为多胞妊娠、分娩而产生的并发症,导致胎儿无法正常分娩,甚至出现流产的状况;

2.患者取出的卵子数量较多或者雌二醇较高,为了降低卵巢过度刺激的反应,在满足移植要求的情况下,不建议移植两个胚胎;

3.患者有心脏病或者高血压史等不适宜妊娠的内科疾病时,为了保证患者的安全,不建议移植两个。
