Peer J:终于可以放心地抽电子烟了!

2018-05-02 Gsdtom 转化医学网

抽电子烟者和不吸烟者的肠道细菌种类相同,而吸烟者的肠道菌群则有显着变化。

导  读

抽电子烟者和不吸烟者的肠道细菌种类相同,而吸烟者的肠道菌群则有显着变化。

由纽卡斯尔大学(Newcastle University)领导的国际研究小组分析了吸烟、吸电子烟和不吸烟的人群消化道(包括口腔和肠道)细菌情况。

抽电子烟者和不吸烟者的肠道细菌种类相同,而吸烟者的肠道菌群则有显着变化

吸烟者肠道细菌发生了显着变化——普氏菌增加了,它与结肠癌和结肠炎的风险有关。

吸烟者的有益菌或益生菌也减少了。

拟杆菌降低与克罗恩病和肥胖有关。

相比之下,那些使用电子烟的人的肠道菌群和不吸烟者一样。

这项研究的主要作者,纽卡斯尔大学细胞医学研究所的Christopher Stewart,今天在PeerJ发表了这一发现。

他解释道:“我们体内的细菌细胞数量超过了我们人类的细胞,微生物比大脑更重,但我们才刚刚开始认识到它对我们健康的重要性。”

“需要进行更多的调查。但知道电子烟对肠道细菌的危害比抽烟要小得多,这增加了人们选择电子烟的趋向,人们可以将其视作一种完全戒烟的工具。”

微生物群比较

这项试点研究首次比较了吸烟者和电子烟使用者的微生物群。

样本取自10名电子烟使用者、10名吸烟者和10名不吸烟的对照组。

通过对粪便,口腔(颊)和唾液样本进行靶向基因测序,来确定细菌情况。

粪便样本中,肠道细菌有了显着变化。

口腔和唾液是直接接触烟草或者电子烟的,这些样本,吸烟者与不吸烟者的细菌是不同的。

但是,和肠道一样,口腔和唾液样本的细菌,抽电子烟者和不吸烟者是相似的。

斯图尔特博士补充说:“因为现在抽电子烟的人群很庞大,所以我们这个研究就很重要,能了解电子烟对人体的影响。”

随着越来越多的人开始使用电子烟,研究小组呼吁有必要进行进一步的研究,他们的目标是在更长的时期内研究一个更大的群体。

他们还建议进一步区分性别进行微生物群的调查,因为这次的研究只选了两名女性。

现在看来,电子烟既能满足吞吞吐吐的惬意,还能减少吸烟对健康的影响。这对于顽固的烟民来说,无疑是个好消息。

不过这并不代表电子烟就可以肆无忌惮地使用了。

Am J Resp Crit Care:长期电子烟暴露改变人支气管上皮细胞蛋白质组!

由此可见,长期接触电子烟对肺脏有显著的生物效应,这些效应可能部分由PG/VG所介导。这些变化可能不是无害的,可能对慢性肺病的发生发展有临床意义。需要进一步的研究以确定电子烟对肺脏的影响程度。

Ann Inter Med:电子烟是不是戒烟的做有效手段,值得探讨!

对既往研究的1,350多名吸烟者的数据进行分析,认为在研究期间使用电子烟报告的吸烟者不太可能在进入研究后6个月内成功戒烟。不过,由于研究的设计,也有专家不能支持这样的结论,即电子烟不是有效的戒烟辅助手段,并强调需要进一步调查这一问题。

Front Physiol:戒烟者注意:有香味的电子香烟是有毒的

最近在“生理学前沿”杂志上发表的研究考察了电子烟蒸气对两种类型白血球的影响。研究结果表明,使电子香烟有味道的化合物是有毒的,有些味道比其他味道更差。

PNAS:电子烟也致癌,还是彻底戒了吧!

电子烟(E-cig)一直被推广为非致癌物和更安全的烟草替代品。然而,1月29日发表在《美国科学院院报》(PNAS)杂志上的最新研究表明,电子烟中的尼古丁会破坏DNA和抑制DNA修复,从而可能导致肺癌和膀胱癌以及心脏病。

PNAS:电子烟无害?大错特错!研究证实电子烟雾有损DNA!

电子烟(ECS)是一种模仿卷烟的电子产品,有着与卷烟一样的外观、烟雾、味道和感觉。它是通过雾化等手段,将尼古丁等变成蒸汽后,让用户吸食的一种产品。然而,国内外均没有系统的电子烟安全性评估资料,因此,目前还不能确定电子烟会给使用者的健康带来哪些潜在风险,其所产生的二手烟,同样可能危及健康。近期有研究表明,ECS可损害小鼠重要器官的DNA,或有致癌风险!

Int J COPD:电子烟和烟草烟雾暴露对COPD支气管上皮细胞炎症反应的影响

电子香烟一直以来是医学上及大众中常见的卷烟代替物用来戒烟过渡物,但一直以来其对人体呼吸道的具体影响并不清楚,本研究通过对电子烟烟雾提取物刺激人类支气管上皮细胞,并发现该提取物的毒性反应机制,引起了同仁的高度重视。
