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.

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.

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 evaluate the research design and the use of statistical methods in Chinese Journal of Cardiology.

METHODPeer through the research design and statistical methods in all of the original papers in Chinese Journal of Cardiology from December 2007 to November 2008.

RESULTThe most frequently used research designs are cross-sectional design (34%), prospective design (21%) and experimental design (25%). In all of the articles, 49 (25%) use wrong statistical methods, 29 (15%) lack some sort of statistic analysis, 23 (12%) have inconsistencies in description of methods. There are significant differences between different statistical methods (P < 0.001). The correction rates of multifactor analysis were low and repeated measurement datas were not used repeated measurement analysis.

CONCLUSIONMany problems exist in Chinese Journal of Cardiology. Better research design and correct use of statistical methods are still needed. More strict review by statistician and epidemiologist is also required to improve the literature qualities.

OBJECTIVETo investigate the referential rule and the informative absorbing capacity of the Chinese Journal of Integrated Traditional and Western Medicine (CJITWM), and analyze the characteristics of literature requirement of scientists working in integrated Chinese and Western medicine (ICWM) field offering suggestions on literary utilization.

METHODSCitation analysis was used to analyze the references cited in 1825 articles published in CJIM from 2001 to 2004 according to their time sequence of publishing.

RESULTSThe citation rate was 53.64%, and 9.51% citations per article. Most of the citations were mainly cited from journals (85.38%) and books (13.4%). The Price Index was 49.22%, and the self-citation rate for author and periodical were 3.63% and 7.77% respectively.

CONCLUSIONCJITWM is a highly authorized and representative professional academic periodical in the field of ICWM. The citations are mainly cited from periodicals written in Chinese or English, they are of good novelty and quality, but the citation rate should be further improved.

OBJECTIVETo explore the articles, authors and citations of the articles published in Chinese Journal of Pediatrics, and have a clear view of the characteristics of this journal in its different development stages.

METHODBibliometric methods were used to analyze the published articles, cooperation, regional distribution, core authors, corresponding authors and high-quantities of publication institutes, and also to calculate the number of citations per paper, types of citations, language-based citation number, Price index, self-cited rate and the distribution of journals based on citations.

RESULTTotally 5534 academic articles were published during the 60 years, of which the number of articles written by more than one author was 4669 (80.71%), with a degree of collaboration as 3.87, and a rate of collaboration as 84.37%. The number of articles by a single author was 865 (19.29%). As for the regions from where the papers were submitted, the top one was Beijing, which had 1495 articles published (27.01%). The top 15 institutes in number of articles had published 2254 articles (40.73%). The average citation rate was 84.15%, and the number of citations was 48 854. The number of citations per paper was 10.06, the Price index and self-cited rate were 55.57% and 6.12%, respectively. The number of citations from foreign language literature was 35 781 (69.1%). The citation number of journals was 43 266 (84.5%), which is markedly higher than the citations of books and others.

CONCLUSIONChinese Journal of Pediatrics has a wide distribution of authors and a high cooperative rate. This journal has a group of high-level core authors since founded in 1950, and it shows an adequate ability of absorbing and using scientific information. The articles published in this journal not only objectively reflected the distribution of the research powers, but also the development status of pediatrics in our country.
