New Attempts to Eradicate AIDS Virus
A high-profile attempt to eradicate the AIDS virus in a few patients continues to show promise.
But researchers won't know for a year or more whether it will work,scientist David Ho told journalists
here Wednesday for the Fourth Conference on Viruses and Infections.
"This is a study that's in progress,"says Ho,head of the Aaron Diamond AIDS Research Center,
New York.
The study involves 20 people who started combinations of anti-HIV drugs very early in the course of the
disease,within 90 days of their infections.They'ye been treated for up to 18 months.Four others have
dropped out because of side effects or problems complying with the exacting drug system.
The drugs have knocked the AIDS virus down to undetectable levels in the blood of all remaining
patients.And,in the latest development,scientists have now tested lymph nodes and semen from a few
patients and found no virus reproducing there,Ho says."Bear in mind that undetectable does not equal
absent,"Ho says.
Ho has calculated that the drugs should be able to wipe out remaining viruses一at least from known
reservoirs throughout the body—in two to three years.But the only way to prove eradication would be to stop
the drugs and see if the virus comes back.On Wednesday,Ho said he wouldn't ask any patient to consider
that step before 2(1/2)years of treatment.
And he emphasized that he is not urging widespread adoption of such early,aggressive treatment outside
of trials.No one knows the long-term risks.
But other scientists are looking at similar experiments.A federally funded study will put 300 patients on
triple-drug treatments and then see if some responding well after six months can continue to suppress the
virus on just one or two drugs,says researcher Douglas Richman of the University of California,San Diego.
Some patients in that study also may be offered the chance to stop therapy after 1 8 months or more,he says.
选项
We prove that the drugs have wiped out the remaining viruses by________.
A:using up all the drugs at once
B:waiting for the virus to die slowly
C:asking the patients'feeling about the disease
D:stopping the drugs to see if the virus comes back
答案
D
解析
由文章第一段可知,消灭艾滋病病毒的努力依然有着乐观的前景,故选C。
由文章第四段最后一句“Four others have dropped out because of side effects or problems complying with the existing drug system.”可知,有4位病人从治疗计划中退出,因为当前的治疗 计划对他们产生了副作用或者其他问题,故选C。
由文章第五段的内容可知,检测不到艾滋病病毒并不等于它不存在,即艾滋病病毒可 能是检测不到,但是它还可能隐藏在人体中,故选A。
由文章第六段第二句“But the only way to prove eradication would be to stop the drugs and see if the virus comes back.”可知,证明所用的药物确实消灭了艾滋病病毒的唯一方法就是先 停药一段时间,然后看病毒是否会重新肆虐,故选D。
由文章的最后三段内容可知,在David Ho的研究中,要确认残余的艾滋病病毒已被药 物消灭的话,需要2一3年的时间。在最后一段中一项由联邦政府资助的研究将测试时间限定 在6个月;一些病人可能在约18个月后停止治疗,故选D。第二篇 本篇文章主要讲述的是不丹王国的国王采用国民幸福指数(GNH)来衡量国家的进步,以及 此举带来的影响。
