This allowed aspirin to become the most widely used medicine in the world.

In recent years its benefits as a blood-thinning drug have led to it being prescribed in lowdoses of around 50mg to reduce deaths from stroke and heart attack.

There were also hints that aspirin may help prevent some cancers.
也有迹象表明阿司匹林可以帮助预防一些癌症。

The results of just such a trial, published in the Lancet, suggest that aspirin is indeed anastonishing drug.

在那些历时4到8年之间的实验中,服用阿司匹林的患者因癌症而死亡的概率比那些服用安慰剂的患者小了21%。
These results were based on 674 cancer deaths, so are unlikely to represent the kind ofstatistical oddity that can beset studies on cancer risks that sometimes create headlines.
这些结果是在674例癌症死亡病例的基础上得出的,所以不大可能是所谓的统计学上的例外。对癌症风险的研究会因这种例外而受挫,有时甚至会闹成大资讯。
The benefits of aspirin were also apparent many years after the trials had ended.
试验结束后的很多年后,阿司匹林的效果也仍旧明显。

这意味着目前还不清楚阿司匹林到底是怎么预防癌症的。

研究人员认为阿司匹林阻碍了一种在肿瘤内部促进细胞增殖的酶的活动。
The researchers also found that small daily doses of aspirin were enough, and that takingmore than 75mg conferred no additional benefits.

Those starting on aspirin in their late 40s or 50s benefit most.
那些从四五十岁末就开始服用阿司匹林的人得到的效果最好。
Current guidelines on using aspirin for reducing the chances of a stroke or heart attackrightly warn of the small risk of ulcers and of dangerous bleeding in the stomach.

By anyone s measure, that is a bargain.
不管按照哪一方的标准,这都是一笔非常划算的交易。
