原标题:Vaping 'can damage vital immune system cells'

蒸汽电子烟可能损坏重要免疫细胞

Vaping can damage vital immune system cells and may be more harmful than previously thought, a study suggests.

一项研究显示,蒸汽电子烟对身体的危害可能比人们之前预想的要大,因为它能够损坏人体重要的免疫细胞。

Researchers found e-cigarette vapour disabled important immune cells in the lung and boosted inflammation.

研究人员发现电子烟产生的气雾将致使肺部重要免疫细胞瘫痪,导致肺部炎症恶化。

The researchers "caution against the widely held opinion that e-cigarettes are safe".

研究人员告诫大众要警惕“电子烟很安全”这种观点。

However, Public Health England advises they are much less harmful than smoking and people should not hesitate to use them as an aid to giving up cigarettes.

然而,英国公共卫生部建议道虽然电子烟产生的气雾有害,但相比吸食卷烟害处还是小得多;因此,想戒烟的烟民应该毫不犹豫地选择电子烟作为辅助。

The small experimental study, led by Prof David Thickett, at the University of Birmingham, is published online in the journal Thorax.

伯明翰大学的大卫·西克特(David Thickett)教授牵头做了一个小型实验性研究,研究结果发表在世界顶级呼吸医学期刊之一的Thorax上。

Previous studies have focused on the chemical composition of e-cigarette liquid before it is vaped.

在此之前,电子烟相关研究的重点均放在液体挥发前的化学成分上。

In this study, the researchers devised a mechanical procedure to mimic vaping in the laboratory, using lung tissue samples provided by eight non-smokers.

而这项研究中,研究人员设计了一整套机械程序,在实验室模拟蒸汽电子烟对肺部组织的影响,肺部组织样本由八位非吸烟者提供。

They found vapour caused inflammation and impaired the activity of alveolar macrophages, cells that remove potentially damaging dust particles, bacteria and allergens.

研究人员发现电子烟产生的气雾会造成肺部组织发炎,致使肺泡巨噬细胞受损,而肺泡巨噬细胞又是将潜在致损性尘粒、细菌以及过敏原移除体外的必要细胞。

They said some of the effects were similar to those seen in regular smokers and people with chronic lung disease.

研究人员称电子烟对人体的影响与常规吸烟者和慢性肺病患者的症状类似。

They caution the results are only in laboratory conditions and advise further research is needed to better understand the long-term health impact - the changes recorded took place only over 48 hours.

他们还称这些结果都是在实验室条件下得出的,需要进一步的研究才能更好地了解电子烟对健康的长期影响;但值得注意的事,在实验室环境下,肺部组织的恶化仅用了48小时。

An independent review of the latest evidence on e-cigarettes was published by Public Health England in February.

今年2月,英国公共卫生部公布了一项对卷烟的独立调查报告。

The review concluded there was "overwhelming evidence" they were far safer than smoking and "of negligible risk to bystanders" and advised they should be available on prescription because of how successful they had been in helping people give up smoking.

该报告称最新的有力证据显示,电子烟远比卷烟安全,对周围人的有害影响可以忽略不计。他们建议道电子烟应该列入处方药的范畴,因为它已经帮助很多人成功地戒除了烟瘾。

E-cigarettes 'should be on prescription'

电子烟“应该列为处方药”。

Prof Thickett said while e-cigarettes were safer than traditional cigarettes, they may still be harmful in the long-term as research was in its infancy.

西克特教授称对电子烟的研究还处于初级阶段,虽然它比传统卷烟更安全,但从长远来看,它的危害也不容忽视。

In terms of cancer causing molecules in cigarette smoke, as opposed to cigarette vapour, there are certainly reduced numbers of carcinogens, he said.

他说“与吸食卷烟相比,使用蒸汽电子烟产生的致癌物确实是少了。

They are safer in terms of cancer risk - but if you vape for 20 or 30 years and this can cause COPD [chronic obstructive pulmonary disease], then that's something we need to know about.

降低了致癌的风险,然而如果使用电子烟20年甚或30年,就会导致慢性阻塞性肺疾病(COPD),这一点是我们都有必要知道的。”

I don't believe e-cigarettes are more harmful than ordinary cigarettes - but we should have a cautious scepticism that they are as safe as we are being led to believe."

西克特教授还说道:“我不认为电子烟对身体的危害比普通卷烟大——但是我们仍需对‘他们很安全’这一观点持有一定的怀疑。”

Martin Dockrell, tobacco control lead at Public Health England, said: "E-cigarettes are not 100% risk-free but they are clearly much less harmful than smoking. Any smoker considering e-cigarettes should switch completely without delay."

马丁·多克雷尔(Martin Dockrell)是英国公共卫生部烟草控制方面的负责人,他表示:“电子烟虽然不是零风险,但其危害明显比吸食卷烟小得多,而那些还在观望是否使用电子烟作为戒烟辅助措施的烟民应立即行动起来。”
