The discovery of artemisinin has helped significantly reduce the mortality rates of malaria patients.

蒿素的发现极大地降低了疟疾患者的死亡率。

Artemisinin is a drug that has sharply lowered the number of people who die from malaria.

蒿素是一种能够在很大程度上降低疟疾死亡人数的药物。

Parasites in South-East Asia, for example, seem to be developing resistance to artemisinin-based treatments.

比如，东南亚的寄生虫似乎对基于蒿素的治疗起了抗药性。

This year marks the 50th anniversary of Tu's discovery.

今是屠呦呦发现蒿素 50 周。

Several partners are now considering an innovative funding facility for making ACTs more affordable.

一些作伙伴目前正在考虑通过新的筹资机制，使以蒿素为基础的联疗法更为便宜。

Tu's research led to the manmade drug artemisinin, a drug now widely used to treat malaria.

屠呦呦的研究引发了人造药物蒿素，这种药物现已广泛用于治疗疟疾。

Tu found it effective and tried to extract the qinghaosu from it in order to make a drug.

屠呦呦发现这种疗法有效，便试图以此提取蒿素来制造药物。

Basically, they were making an extract of qinghao without heating it at all.

也就是说，他们在制作蒿提取物时不进行加热。

It turned out that qinghaosu was safe and all patients in the test recovered.

结果表明蒿素是安全的，所有接受测试的患者了。

She used a low-temperature method to extract the qinghaosu and finally succeeded in 1972.

屠呦呦用低温法提取蒿素，并最终于 1972 成功。

Artemisinin is the most effective Malaria treatment ever developed. But across Southeast Asia resistance to it is a growing concern.

蒿素是开发出来的治疗疟疾的最有效药物，但整个东南亚地区寄生虫对这种药物的抗性令人担忧。

Now, artemisinin can be toxic to human cells, too, for the same reason.

不过，蒿素也会对人体细胞产生毒性，也是出于同样的原因。

And when artemisinin encounters hemozoin, the two compounds react to create unstable atoms known as free radicals.

当蒿素遇到疟原虫色素时，这两种化物会发生反应，产生被称为自由基的不稳定原子。

Even with large amounts of qinghao extract produced, however, they still faced another problem.

然而，即便是大量的蒿提取物，他们也面临着另一个问题。

Tu Youyou is a Chinese scientist who managed to extract artemisinin from a Chinese herb.

屠呦呦是一位中国科学家， 他成功地从中草药中提取了蒿素。

A fancy banquet was served with artichokes, fish, chicken, and wine.

宴会上提供了一道精美的菜肴, 包括蒿、鱼、鸡肉和葡萄酒。

As it turned out, the key to this life-saving cure was an active compound from the wormwood plant called artemisinin.

事实证明，这种救命疗法的关键是一种来自艾草植物的活性化物，叫做蒿素。

She was, of course, recognized for her discovery of artemisinin, the powerful medicine used to treat malaria.

当然，她因发现用于治疗疟疾的强效药物蒿素而受到认可。

But luckily, artemisinin reacts more readily with hemozoin, than it does with the iron in our cells.

但幸运的是，蒿素与疟原虫色素的反应比与我们细胞中的铁反应更容易。

But then, while looking back over her notes, Tu found an interesting reference to the herb qinghao, also known as sweet wormwood.

但是后来，在回顾她的笔记时，屠呦呦发现了一种有趣的草药——蒿，也被称为苦艾。
