希尼尔翻译公司（www.sinosenior.com.cn）2018年7月31日了解到：Scholars from University of California, San Francisco have found that people who consume E-cigarettes and tobacco product are more likely to develop oral cancer, a US non-profit advocating oral health said over the weekend.

加利福尼亚大学旧金山分校的学者们发现，吸电子烟和烟草制品的人更有可能患上口腔癌，一提倡口腔健康的美国非盈利组织于周末表示。

The International Association for Dental Research said UC San Francisco researchers Benjamin Chaffee and Neal Benowitz, the co-author of a paper on nicotine and carcinogen exposure from consumption of tobacco product, examined the risks of people who are exposed to known carcinogen resulting from the use of different tobacco products, alone or in combination.

国际牙科研究协会表示，Benjamin Chaffee和Neal Benowitz是加州大学旧金山分校的研究人员，他们共同撰写了一篇关于消费烟草制品产生的尼古丁和致癌物质的论文，并研究了暴露在由于单独或组合使用不同烟草制品产生的致癌物质中的人们面临的风险。

They assessed a national sample of 32,320 US adults collected between 2013 and 2014, who provided urine specimens for analysis of tobacco-specific nitrosamines, N’-nitrosonornicotine, a known oral and esophageal carcinogen, and 4-(methynitrosamino)-1-(3)-pyridyle-1-butanol (NNAL), a metabolite of lung carcinogen, as well as total nicotine equivalents.

他们评估了于2013年至2014年间收集的32,320名美国成年人参与其间的全国样本，参与者提供了尿液标本，用于分析烟草特有的亚硝胺，一种已知的口腔和食道致癌物N’-亚硝基去甲烟碱，肺部致癌物质的代谢产物4-（甲基亚硝基氨基）-1-（3）-吡啶-1-丁醇（NNAL）以及总尼古丁当量。

Among the participants, 48 percent are female and 61 percent non-Hispanic white aged from 18 years old to 90 years old, with a median age of 35 years.

参与者当中，48％是女性，61％是非西班牙裔白人，年龄从18岁到90岁不等，平均年龄为35岁。

More than 6,000 of them were characterized according to use of combustible products such as cigarettes, cigars, waterpipe, pipes, marijuana-containing cigar, smokeless products including moist snuff, chewing tobacco, snus, and e-cigarette, as well as nicotine replacement products.

6000多名参与者依据香烟、雪茄、水烟、烟斗和含有大麻的雪茄等可燃产品，湿鼻烟、嚼烟、鼻烟和电子烟在内的无烟产品以及尼古丁替代产品这三类不同产品的使用情况而各具特点。

The researchers found that all tobacco use categories showed elevated nicotine and TSNA concentrations compared to non-users.

研究人员发现，与非吸食烟草者相比，所有烟草使用类别都显示尼古丁和有毒物质亚硝胺化合物浓度升高。

Smokeless tobacco users have the highest level of TSNA exposure, whether they use one tobacco product or together with other product types.

无烟烟草吸食者具有最高水平的有毒物质亚硝胺化合物浓度，无论他们使用一种烟草产品还是与其他产品类型一起使用。

The study discovered that the vast majority of non-cigarette tobacco users are exposed to carcinogen levels that are likely to put them at substantial risk, just as much as exclusive cigarette smokers would suffer.

该研究发现，绝大多数非卷烟烟草使用者暴露于可能置他们于巨大风险的致癌物质水平之中，并会受到香烟对吸烟者一样大的影响。
