scientists have been searching for a cure for HIV AIDS for close to 40 years . those leading the fight against AIDS at the un call News but also shows how far we are from the point of ending AIDS with science as well as the absolute importance to continue to focus on HIV prevention and tread

近40年来,科学家们一直在寻找艾滋病(AIDS)病毒(HIV)的治疗方法。在联合国领导艾滋病攻防战的人表示,英国一名男子治疗艾滋病的消息是重大突破。这次突破给未来带来了重要的希望,但也说明了我们离结束艾滋病还有多远,以及持续关注艾滋病毒的预防和治疗有多重要。(大卫亚设,Northern Exposure)伦敦患者现在完全没有艾滋病毒。接受一次干细胞移植后,干细胞捐献者具有罕见的基因免疫能力,可以阻止HIV,因此伦敦患者不再需要接受HIV治疗。

we wait 16 months before stopping in the post-transplant period just to make sure that the cancer was in remission . the patient was well;measures we had of the HIV reservoir in the body showed that there was very very little virus there,if any at all . Gupta hesitates to call it a cuu buu you may protect those new cells from infection . but stem cell treatment is not a practical cure for the 37 million people across the globe who ho vehho

我们等了16个月才停止后期移植,只是为了确认癌症已经处于缓解期,患者的健康状况是否良好。对患者体内HIV病毒量的测量结果显示,病毒含量接近于0。古普塔不确定是否应该称之为痊愈,但他表示,这是一个重大进展。这是没有艾滋病毒痕迹的第二个患者。之前的第一个患者也做了类似的干细胞移植手术。第一个患者来自美国,12年前在柏林接受了治疗。如果把这些干细胞移植到HIV患者体内,这些新细胞就不会感染。但是干细胞移植对全世界3700万HIV患者来说不是真正的治疗方法。不仅价格昂贵,而且很难找到具备基因免疫力的匹配对象。治疗过程本身不仅痛苦,而且风险很高。

having a bone marrow transplant ation is a very complicated process . it requires an entire new set of cells to be taken into it into the person who Ving the And that again is a process where whilst those cells are embedding your very impact risk of getting infections And potentially dying . both the long And meaning it is possible to nearly or maybe even completely eliminate HIV from the body of an infected person . scientists will continue to search for Her

骨髓移植过程很复杂,所以需要将新的细胞集移植到患者身上进行治疗,这个过程如上所述,可以防止患者感染或死亡。(大卫亚设,Northern Exposure(美国电视),骨髓移植名言)无论是伦敦患者还是柏林患者都得过癌症,他们不得不冒这个大风险。第二次成功唤起了人们的乐观精神。我们现在有理由相信柏林患者的病例可以复制。也就是说,让HIV患者清除病毒是可能的。科学家们将继续搜索其他方法来治疗HIV,但至少现在知道艾滋病可以治愈,或者至少可以缓解。
