OBJECTIVEThe present study was designed to explore the cited status and its correlated factors of articles published in Chinese Journal of Pediatrics.

METHODArticles published in Chinese Journal of Pediatrics from 2001 to 2010 were searched using Wanfang Medical Online database, and the relationship between cited number and column and funding status were analyzed.

RESULTSTotally 3209 articles were published by Chinese Journal of Pediatrics from 2001 to 2010. Two thousand and seventy-three articles (64.60%) were cited. The total cited number was 18 546 (mean rate: 5.78 per paper). Standard/protocol/guideline was the most often cited column (mean rate: 62.92 per paper). Featured articles including editorials (mean rate: 7.12 per paper), special articles (mean rate: 6.50 per paper) and original articles (mean rate: 7.90 per paper) had higher cited rate. Cited rate of original papers in featured articles was higher than other original articles (mean rate: 6.03 per paper). Those with academic perspectives, such as Opinion/Debate/Discussion, were well cited (mean rate: 7.09 per paper). All of original articles in Rapid Pathway were well cited (mean rate: 16.20 per paper). Mean cited number of grant-supported articles was 4.81 per paper, lower than that of all kinds of papers (mean rate: 5.78 per paper) and non-grant-supported articles (mean rate: 6.06 per paper). However, it was slightly higher than that of articles except Standard/protocol/guideline (mean rate: 4.36 per paper).

CONCLUSIONCited status varies among columns. The invited papers should be increased in number to raise commentary papers and original articles with high quality.Grant-supported or non-grant-supported papers should be reviewed based on the same standard after submission.

CONCLUSIONChinese Journal of Burns, an academic journal of high quality, with strong influence, pushes the discipline of Burns medicine in China forward.

OBJECTIVETo evaluate the quality of articles and the popularity of Chinese Journal of Pediatrics.

METHODSWith the database of Chinese Science & Technology Journal Citation Reports 2000-2003, the six indicators, including impact factor (IF), total cited numbers, immediate index, ratio of cited numbers by other journals to total cited numbers, number of citing journals, and cited half-life were evaluated and compared with other Chinese periodicals in pediatrics and related subjects. The cited numbers, distribution of cited areas, and cited institutions of published articles in Chinese Journal of Pediatrics 2000-2003 were analyzed.

RESULTSFrom 2000 to 2003, the impact factor of the Journal was 0.937, 1.025, 1.052, 1.252, total cited number was 1378, 1468, 1863 and 2396. Immediate index, citing journals, and cited half-life rose steadily, and the ratio of cited numbers by other journals to total cited numbers remained above 0.9. The average cited number of articles was 3.3. The cited authors were from 26 provinces or cities.

CONCLUSIONThe Chinese Journal of Pediatrics ranked at the top of Chinese pediatric journals with its highest IF and total cited numbers, which indicates that the journal has explicit editorial aims, stable continuity, and the increased influence in Chinese pediatric research. The stable growth of immediate index, number of citing journals and cited half-life show that the Journal has a high rate of reflection, the articles published in the Journal were paid more attention and have influenced researchers for longer periods and widely. The higher rate of citation by others and lower self-cited rate indicate that the Journal has been rigorous and realistic in editorial practice. The Journal is demonstrated to be one of the main medical core periodicals and one of the most important information sources in the field of pediatrics in China.

BACKGROUND: This study was undertaken to investigate the trends of orthopedic publications during the last decade, and to document the country of origin, journal, funding source, and language of contribution using PubMed. METHODS: Orthopedic articles published between 2000 and 2009 were retrieved from PubMed using the following search terms: "orthopaedic[Affiliation] AND ("2000/1/1"[PDAT]: "2009/12/31"[PDAT])" and "orthopedic[Affiliation] AND ("2000/1/1"[PDAT]: "2009/12/31"[PDAT])." The articles were downloaded in XML file format, which contained the following information: article title, author names, journal names, publication dates, article types, languages, authors' affiliations and funding sources. These information was extracted, sorted, and rearranged using the database's management software. We investigated the annual number of published orthopedic articles worldwide and the annual rate of increase. Furthermore, the country of publication origin, journal, funding source, and language of contribution were also investigated. RESULTS: A total of 46,322 orthopedic articles were published and registered in PubMed in the last 10 years. The worldwide number of published orthopedic articles increased from 2,889 in 2000 to 6,909 in 2009, showing an annual increase of 384.6 articles, or an annualized compound rate of 10.2%. The United States ranked highest in the number of published orthopedic articles, followed by Japan, the United Kingdom, Germany, and the Republic of Korea. Among the orthopedic articles published worldwide during the last 10 years, 37.9% pertained studies performed in the United States. Fifty-seven point three percent (57.3%) of articles were published in journals established in the United States. Among the published orthopaedic articles, 4,747 articles (10.2%) disclosed financial support by research funds, of which 4,688 (98.8%) articles utilized research funds from the United States. Most articles were published in English (97.2%, 45,030 articles). CONCLUSIONS: The number of published orthopedic articles has been increasing over the last decade. The number of orthopedic articles, journals publication, and funding sources were dominated by research conducted in the United States, while share and growth of Asian countries including Japan, the Republic of Korea, and China were notable.

OBJECTIVETo explore the status of articles published in Chinese Journal of Pediatrics from 2005 to 2014.

METHODAll the articles published in Chinese Journal of Pediatrics from 2005 to 2014 were searched at Wanfang Medical Online database. The total number and citations of articles, authors, agency, single article citation, internet downloads, columns, fund and Mesh were analyzed. The end of searching period was January 2015.

RESULTFrom 2005 to 2014, 2814 articles were published in Chinese Journal of Pediatrics, 235 to 380 articles per year. A total of 1 596 articles were cited, the citation rate was 56.16%, total number of citation was 15 428. Among single article citations, of the top 20 articles, 55% (11/20) were those published in the Standard/Protocol/Guide column. Of the top 20 papers most frequently downloaded on internet, 100% were articles published in the Standard/Protocol/Guide column. During the recent 10 years, the source of the papers published in the journal covered 31 provinces, municipalities and autonomous regions. The column that published the largest number of articles was Original Article (911, 32.05%), followed by Case Report (336,11.82%) and Review (245, 8.62%). Of the total number of articles published in the journal, 747 were supported by fund, which accounted for 26%. The articles supported by national fund accounted for 8%.

CONCLUSIONArticles published in Chinese Journal of Pediatrics had high-quality and can reflect the development and research progress in pediatric medicine. It is one of the most important information resources in pediatric academic fields in China.

OBJECTIVETo identify the characteristics of the articles published in Zhonghua Nan Ke Xue (National Journal of Andrology, NJA) and the distribution of the authors in the andrological world.

METHODSArticles published in NJA between 2009 to 2012 were collected and analyzed using statistic and bibliometric methods. The indicators include cooperation degree, core authors, distribution of grant articles, and geographical distribution of authors.

RESULTSDuring the 4 years, 1064 articles were published in NJA, of which 998 (93.80%) were coauthored, with a cooperation degree of 4.72. Totally, 909 authors, including 792 (87.13%) of the first authors, published 1 article each; 272 (25.56%) papers were written by 117 (12.87%) core authors, and 396 granted by 619 foundations. There were 13 high-productivity institutions, which published a total number of 257 (24.15%) articles. As for geographical distribution, Jiangshu, Guangdong and Beijing ranked as the top three, contributing 215 (20.21%), 105 (9.87%) and 102 (9.59%) of the published papers, respectively. Among the published papers, 132 were cited for 185 times by 119 journals in SCI, and another 418 cited for 701 times by 94 journals in CSCD.

CONCLUSIONNJA has a high cooperation degree and a wide geographical distribution of authors, with Jiangshu, Guangdong and Beijing as the top three areas in andrological research, though the overall geographical distribution is not well balanced. NJA is receiving more and more attention from both domestic and international researchers.

OBJECTIVEThis study was designed to investigate the influence of journals indexed by Science Citation Index (SCI) on Chinese medical journals.

METHODArticles on medicine written by Chinese and the journals that published these articles from 2000 to 2009 were searched using Science Citation Index Expanded (SCI-E) database, and the status and variation tendency of the impact factors (IF) of these journals were analyzed. Data of articles on medicine included Chinese Scientific and Technical Paper and Citations Data (CSTPCD) from 2000 to 2008 were searched (the data of 2009 have not been released). The included articles and the time-dependent changing profile were studied. These outcomes were evaluated as the fixed base relative or link relative when compared with the data of 2000 or those of last year, respectively. Geometric mean was used when mean increase was calculated and IF distribution was described with median.

RESULTTotally 3774 articles from China were published by journals indexed by SCI-E in 2000, and the number of articles published by Chinese authors increased every year. In 2008, 16 714 articles were indexed by SCI-E, 442.87% higher than those of 2000. The increment was 161.54% higher than that of articles published in the journals indexed by CSTPCD (281.33%) during the same period. From 2000 to 2009, the geometric mean of increase in the number of published articles from China in journals indexed by SCI-E was 20.87% but it was 18.21% in CSTPCD. From 2000 to 2009, the median of IF of SCI-E indexed journals that published Chinese medical articles was 1.866, 2.073, 2.390, 2.702, 2.409, 2.496, 2.380, 2.218, 2.280 and 2.331, respectively, and they did not increase or even decreased.

CONCLUSIONThe number of the articles indexed by SCI-E increased year by year, much faster than that of CSTPCD. However, it does not necessarily mean the increase in impact.
