Chinese Journal of Ophthalmology and me

中华眼科杂志创刊至今已60年了,作为本刊的老编委,我的心中感概万分.1955年我从浙江医学院(现浙江大学医学院)毕业并从事眼科专业,那时对国内仅有的一本眼科专业杂志的期待和关心是可想而知的,所以每一期杂志出版后我都如饥似渴地阅读、再阅读.我在担任眼科医师早期就紧密结合临床实践撰写一些病例报告,尽管今天看来是肤浅的治疗经验,但是编辑部都能认真热情地对待作者,不厌其烦地修改,使我们这些刚踏入眼科临床的医师能有机会学习科研方法.最早的一篇文稿为远距创伤性视网膜病变,描述的是1位农民,由于房屋倒塌致使一侧骨盆骨折,导致双眼视力模糊不清,请眼科会诊,结果发现双眼底后极部有软性渗出。

Citation analysis of three ophthalmology journals

To find the reference aspects of three ophthalmology journals published in China, the United States and the United Kingdom to discover the characteristics of literature requested by different ophthalmic researchers. Citation analysis was used to analyze the references cited in articles published by three different journals, the American Journal of Ophthalmology (AJO), British Journal of Ophthalmology (BJO) and Chinese Journal of Ophthalmology (CJO). Variable parameters include number, types and chronology distribution of the references, Price Index, Self-citing rate and top cited journals of these three journals. The average number of references per article in AJO, BJO and CJO was 12.67, 21.31 and 11.50, respectively. The Price Index was 37.12%, 33.47% and 44.42% in AJO, BJO and CJO, respectively. The self-citing rate was 13.39%, 7.54%, and 9.89% in AJO, BJO and CJO, respectively. There were 1140, 1487 and 724 different journals cited by AJO, BJO and CJO, respectively. The top 13 of them accounted for 58.82%, 49.51%, and 46.39% of all references cited in AJO, BJO and CJO, respectively. These three journals exhibited unique trends in references cited. BJO has more references per paper than the other two journals and has a lower self-cited rate and longer citing half-life. Percentage of the top 13 journals in references cited in AJO is greater than that in the other two journals and AJO has a higher self-cited rate. While CJO cited more recently published references with a higher Price Index and has a moderate self-cited rate.

To evaluate the researcher's productivity by analyzing the citation statue of articles published in Chinese Journal of Ophthalmology (CJO). Using the database of Chinese Medical citation Index (CMCI), the citations from the CJO were collected and analyzed with the bibliometric methods. 1513 papers were published in CJO by 990 authors from 2001-2006 (6 years). 2611 citations by all different journals were found from 705 CJO papers by 479 authors. 748 authors (75.6% of total first authors) published only one paper, while 50 core authors published over 4 papers during 6 years. Beijing was ranked the first with 412 papers and 666 citations, Guangdong Province the second with 235 papers and 632 citations according to the distribution. 851 papers (55.6%) and 1611 (61.7%) citations were from 17 well-respected institutions. The top of rank was Zhongshan Ophthalmic center of SUN Yat-sen University with 198 papers and 526 citations, followed by Beijing Tongren Ophthalmic Center of Capital University of Medical Sciences with 140 papers and 237 citations. The results indicate that the published papers from CJO in recent 6 years are extensively cited, suggesting that the core authors are active and publish most important papers. Beijing, Guangdong and shanghai are most productive in publication of article in CJO even though the authors are widely distributed in the nation.

Analysis of fund sponsored articles from five ophthalmologic journals in 2005

To reveal the features of fund sponsored articles and the status of scientific research by analyzing fund sponsored articles from 5 ophthalmologic journals in Chinese. Five ophthalmologic journals (Chinese Journal of Ophthalmology, Chinese Journal of Ocular Trauma and Occupational Eye Disease with Ophthalmic Surgery, Chinese Ophthalmic Research, Chinese Journal of Practical Ophthalmology, Chinese Journal Ocular Fundus Disease) published in Chinese in 2005 were selected for this study. The amount, the distribution of region, the number of co-authors, the research direction, the number of funds obtained by each paper and the distribution of subjects in various research fields of fund sponsored articles were calculated by quantitative analysis methods. Among 1745 articles published in 2005, 222 were supported by various funds (12.72%). Articles sponsored by national, province/ministry and other sources accounted for 4.70%, 4.81% and 3.21% of all articles, respectively. The highest numbers of co-authors was 5.21. The top region of authors was located in Guangdong Province, which published 71 over 222 papers (31.98%). One hundred and forty nine papers (67.12%) were sponsored by single fund. The subject of fund sponsored articles were mainly in the field of retina (22.97%, 51/222), cornea (17.12%, 38/222) and lens (11.26%, 25/222). The quantity and the level of fund sponsored articles had been improved greatly in ophthalmology journals. However, this is still inferior to other bio-scientific journals. The whole academic level of ophthalmology journals should be further promoted.

Analysis of the quality of clinical trials about therapeutic research using the standard of evidence-based medicine

To investigate the quality of clinical trials of ocular therapeutic efficacy in China in order to provide the facts to support the Evidence-Based Medicine (EBM) and improve the clinical research trials. All the articles published in Chinese Journal of Ophthalmology from 1983 to 2002 emphasizing random control trial and clinical control trial were evaluated as per EBM standard. The total number of articles for clinical therapeutic efficacy published in the past 20 years were 152, of which 35 articles (23.0%) were random control trials, and 8 (5.3%) articles were clinical control trials. The disparity of quality of research was found as follows. The method of random/half random was described in 10 articles (23.3%). Placebo-control and open-control were reported in 3 (3/43) and 9 articles (20.9%), respectively. Blinded, double-blinded, and single-blinded research was adopted in 7 (16.3%), 3 articles (7.0%), and 4 articles (9.3%), respectively. Ten articles (23.3%) reported strict diagnostic standard including inclusion and exclusion standards while 30 articles (69.8%) didn't use exclusion criteria. Follow-up visits from a few months to years was found in 30 out of 43 articles, of 25 articles (58.1%) provided detailed follow-up visit data; 19 articles (44.2%) didn't supply any information of the cases lost follow-up, only 7 articles (16.3%) reported the cause and process of the cases lost follow-up. Adverse events were not consistently reported in the articles. Not a single article estimated sample size when the study was designed. Most articles included small or medium size samples, while lacking of multi-center, large sample, randomized, double-blinded and placebo-controlled clinical trials. Statistical significance for either part or all data except P value was not indicated in 15 articles (34.9%). The indexes assessing the clinical significance of clinical therapeutic efficacy include relative risk reduction, absolute risk reduction, number needed to treat, however, these indexes were not used in all the articles. In summary, the clinical trials related to ocular therapeutic efficacy published between 1983 and 2002 were not very well designed and the accuracy and the reliability of the results were greatly affected. Therefore, it is imperative to improve the quality of the research by enhancing the design and analysis of the research in future.
