People of Chinese ethnicity are one of the groups at most risk of gastrointestinal and liver diseases in the world. The research status in gastroenterology and hepatology (gastrointestinal [GI]) among Chinese individuals in the three major regions of China-the mainland (ML), Hong Kong (HK), and Taiwan (TW)-are unknown. The outputs of articles published in international GI journals from the three regions were compared in this study.
Articles published in 52 journals related to GI originating from the ML, TW, and HK from1996-2005 were retrieved from the PubMed database. The numbers of total articles, clinical trials, randomized controlled trials, case reports, impact factors (IF), citation reports, and articles published in the top general medical journals were conducted for quantity and quality comparisons.
The number of articles from the three regions increased significantly from 1996 to 2005. There were 5170 articles from the ML (2969), TW (1551), and HK (650). However, nearly 90% of articles from the ML were published in World Journal of Gastroenterology (WJG), a controversial Chinese journal. Following the exclusion of WJG, the ML had published the least number of articles and had the least total citations. The accumulated IF of the articles from TW (3747.893) was much higher than the ML (775.084) and HK (2272.972). HK had the highest average IF of articles in GI journals and the most articles published in the top, general medical journals among the three regions.
The difference between the number of GI research articles published in the ML, TW, and HK still appears to be considerable, particularly when assessed by IF, although the gap appears to be narrowing.
华裔人群是世界上胃肠道和肝脏疾病风险最高的群体之一。中国三个主要地区——中国大陆（ML）、香港（HK）和台湾（TW）——华人在胃肠病学和肝病学（胃肠道[GI]）方面的研究现状尚不清楚。本研究比较了这三个地区在国际胃肠病学期刊上发表文章的产出情况。
从PubMed数据库中检索1996年至2005年在ML、TW和HK的52种与胃肠病学相关期刊上发表的文章。对文章总数、临床试验、随机对照试验、病例报告、影响因子（IF）、引用报告以及在顶级综合医学期刊上发表的文章数量进行了数量和质量比较。
1996年至2005年，这三个地区的文章数量显著增加。ML有5170篇文章（2969篇），TW有1551篇，HK有650篇。然而，ML近90%的文章发表在有争议的中文期刊《世界胃肠病学杂志》（WJG）上。排除WJG后，ML发表的文章数量最少，总引用次数也最少。TW文章的累计影响因子（3747.893）远高于ML（775.084）和HK（2272.972）。在这三个地区中，HK在胃肠病学期刊上发表文章的平均影响因子最高，在顶级综合医学期刊上发表的文章数量也最多。
ML、TW和HK发表的胃肠病学研究文章数量之间的差异似乎仍然相当大，尤其是按影响因子评估时，尽管差距似乎在缩小。
