Abstract: 
AIM: To discuss the variations and distributions of authors who published 
their papers in World Journal of Gastroenterology (WJG) during 2001-2007 
and evaluate the development of WJG and gastroenterology core journals in 
recent years by comparing the contributions of the authors.

METHODS: WJG articles published in 2001-2007 were searched from MEDLINE 
database (by ISI Web of Knowledge). The variations (cooperation degree, 
cooperation rate) and distributions of the first authors were analyzed 
with bibliometric methods. SCIE was used to collect articles published in 
Am J Gastroenterol, Gastroenterology, Scand J Gastroenterol and WJG in 
2007, and comparison of the data was made. Comparison indicators included 
the article number of annual journals, cooperation degree of authors, 
cooperation rate, mean number of articles published in each WJG issue, 
number of countries of the first WJG authors, geographical distribution 
and article contribution ratio of all WJG authors and domestic authors.

RESULTS: Of the 5851 articles covered in MEDLINE, 173, 236, 633, 826, 
1496, 1382 and 1105 articles were cited from 2001 to 2007. The cooperation 
degree was 5.11, 5.56, 5.75, 5.76, 6.31, 5.90 and 5.64 respectively. The 
cooperation rates was 94.80%, 99.15%, 98.89%, 98.55%, 99.13%, 96.67% and 
95.66%, respectively. The mean number of articles published in each WJG 
issue from 2001 to 2007 was 28, 39, 52, 34, 31, 28 and 23, respectively. 
The number of countries of the first WJG authors was 8, 8, 27, 32, 49, 61 
and 56, respectively. The first authors of WJG came from 3 continents in 
2001 and covered 6 continents in 2006-2007. The number of articles written 
by Asian authors was 136 (79.07%), 227 (96.19%), 575 (90.98%), 713 
(87.81%), 1111 (75.32%), 712 (53.98%) and 555 (53.21%), respectively in 
2001-2007. The number of articles written by European & American authors 
increased from 36 (20.93%) and 8 (3.39%) in 2001-2002 to 563 (42.68%) and 
452(43.34%) in 2006-2007. The number of countries except for China 
contributing papers was increased. The number of articles written by first 
authors of Japan rose from 0 (0%) in 2001-2002 to 287 (12.15%) in 2006-
2007. The number of articles written by American authors increased from 6 
(1.47%) in 2001-2002 to 158 (6.69%) in 2006-2007. The number of articles 
written by Chinese authors was 136 (79.07%), 227 (96.19%), 548 (86.71%), 
669 (82.39%), 884 (59.93%), 380 (28.81%) and 320 (30.68%), respectively, 
in 2001 to 2007. The number of articles published in Am J Gastroentero% 
Gastroenterology, Scand J Gastroenterol and WJG was 565, 586, 238 and 
1118, respectively in 2007. The cooperation degree was 4.77, 6.14, 5.95 
and 5.64, respectively, in 2007. The cooperation rate was 95.40%, 84.18%, 
96.63% and 95.66%, respectively, in 2007. The number of countries of 
authors contributing papers was 44, 35, 42 and 62, respectively, in 2007.
CONCLUSION: The geographical distribution of WJG authors is wide for the 
past 2 years. WJG has made a step onto international publishing, and drawn 
even more attentions from gastroenterology researchers. Its authors are 
distributed over 74 countries in 6 global continents, and the journal has 
become the main intermediary for international gastroenterology 
researchers to demonstrate their research accomplishments. (C) 2008 WJG.
