With the widespread exposure of people to nicotine through recreational use of tobacco products, research into nicotine has attracted increasing attention. Tobacco smoking is by far the most important cause of lung cancer. As the world's largest producer and consumer of tobacco products, China bears a large proportion of the global burden of smoking-related disease; therefore, information on nicotine publications should be collected to formulate future research policy. In the present study, we investigated nicotine-related research articles published by Chinese authors that were indexed in the Science Citation Index (SCI) from 1991 to 2007. An indicator "citations per publication" (CPP) was used in the study to evaluate the impact of journals, articles, and institutes. The quantity of publications has increased at a quicker pace than the worldwide trend. Article visibility, measured as the frequency of being cited, also increased during the period. However, the overall quality of articles, based on the impact factor of journals publishing those articles, dropped behind the worldwide average level. There has been an increase in international collaboration, mainly with researchers in the USA. The average CPP of international co-authorship articles was higher than that of single country publications. Besides the USA, nicotine research in China will benefit from more collaboration with Taiwan, England, and Germany. Some 110 of 264 articles were published by a single institute, and the top six institutes were compared from various angles. Seventy-two subject categories were covered, and trends (in terms of both quantity and quality) of nicotine research in China were compared with worldwide trends. In addition, analysis of keywords in both nicotine and lung cancer research fields was applied to indicate research interests. Mutual cooperation among multiple disciplines needs further strengthening.
随着人们通过烟草制品的消遣性使用而广泛接触尼古丁，对尼古丁的研究已引起越来越多的关注。吸烟是迄今为止肺癌的最重要病因。作为世界上最大的烟草制品生产国和消费国，中国承担着全球与吸烟相关疾病负担的很大一部分；因此，应收集有关尼古丁出版物的信息，以制定未来的研究政策。在本研究中，我们调查了1991年至2007年被科学引文索引（SCI）收录的中国作者发表的与尼古丁相关的研究文章。本研究使用了一个指标“每篇出版物的引用次数”（CPP）来评估期刊、文章和机构的影响力。出版物数量的增长速度快于全球趋势。以被引用频率衡量的文章可见度在此期间也有所增加。然而，根据发表这些文章的期刊的影响因子来衡量，文章的整体质量落后于全球平均水平。国际合作有所增加，主要是与美国的研究人员合作。国际合著文章的平均CPP高于单一国家出版物。除美国外，中国的尼古丁研究将受益于与台湾、英国和德国的更多合作。264篇文章中有约110篇是由单个机构发表的，并从多个角度对排名前六位的机构进行了比较。涵盖了72个学科类别，并将中国尼古丁研究的趋势（在数量和质量方面）与全球趋势进行了比较。此外，对尼古丁和肺癌研究领域的关键词进行了分析，以表明研究兴趣。多学科之间的相互合作需要进一步加强。
