Purpose To analyze the contents of domestic and inter national public ations in neuro-ophthalmology during the past decade. Methods CBM and Medline were separately searched in 2007, by using Medical subject heading for retrieving Chinese and English language neuro-ophthalmic articles which were published between 1997 and 2006. Results A total of 13052 Englishwritten a rticles available for analysis were contributed from more than 70 countries, mainly from USA, United Kingdom, Japan, Germany, Italy and Canada. The order of frequency was visual cortex（4496/13052，34.4%），optic nerve diseases（3870/13052，29.7%），ocular mo tility disorders（2899/13052,22.2%），visual pathway（1191/13052,9.1%）pupil dis orders(596/13052，5.6%). While a total of 3726 articles were retrieved from CBM, the order of frequency being optic nerve diseases（1854,49.8％），ocular motili ty disorders(excluding strabismus, 1357,36.4%),pupil disorders (242, 6.5%)，visual cortex(202, 5.4%), visual pathway(excluding retina, optic nerve, visual cortex, 71). Researchers with diverse specialties contributed to the neuro-ophthalmic publications. Compared with international counterpart, domestic articles relate d to basic researches were much less. Conclusion Neuro-ophtha lmoloy is interdisc iplinary with a wide range of researches and various study hotspots. Domestic basic researches on neuro-ophthalmology remain to be strengthened and improved. (Chin J Ocul Fundus Dis,2008,24:99-102)
为了解我国南方地区肺栓塞的现状,通过检索中国医院数字图书馆近9年(1999年～2008年)南方地区正式发表的与肺栓塞和深静脉血栓有关的论文共1288篇,进行了统计分析,发现:1、中国南方地区肺栓塞的发现数量逐年增加,且增幅明显;2、诊断水准达到一定程度的部分南方医院,诊断治疗肺栓塞的数量明显高于其他医院,并不比中国北方同类医院低;3、肺栓塞的漏诊、误诊现象依然普遍存在,提高认知和诊治水准仍然是今后工作的方向。
Objective To compare and review worldwide journals titled “evidence-based” in order to provide an overview of these healthcare journals and suggestions for improving the quality of this type of journal in China and to introduce a quick way for healthcare professionals and patients to obtain high quality clinical evidence. Methods We searched PubMed, EMBASE, Ulrich’s Periodicals Directory, Wanfang and some relevant websites to identify journals titled “evidence-based”. The last issues in 2006 of these kind of journals were analyzed by bibliometric method. Results Twenty-four journals were included. Covering 12 disciplines such as clinical, nursing, health care, etc. They were divided into the primary journals and the secondary journals, published in two languages in six countries. These journals had differences and similarities in their aims, columns and contents, etc. Conclusions Evidence-based medical journals provide the latest developments and the best evidence for healthcare professionals in their own fields, save their time in searching for and reading information, and provide ideas for improving the quality of similar journals in our country.
ObjectiveTo investigate the hotspots from researches on imaging of pancreatic neuroendocrine tumor in recent five years. MethodsThe bibliographies from research literatures on imaging of pancreatic neuroendocrine tumor from 2010 to 2015 in PubMed database were downloaded. The Bicomb 2.0 bibliographies analysis software was used to count high-frequency of Mesh major topics (MJMEs). SPSS 22.0 statistical software was applied for clustering analysis with MJMEs, then to get the topic hotspots. ResultsA total of 357 literatures were screened out during the years of 2010-2015. The MJMEs which frequency > 13 were 28. Taken the 28 MJMEs into clustering analysis, then three research hotspots were clustered. ConclusionResearches on imaging of the pancreatic neuroendocrine tumor in recent five years are mainly in terms of imaging techniques, a comparative study of pathology and endoscopic ultrasonography-fine needle aspiration, imaging and disease treatment.
ObjectiveTo investigate the capability and demands of medical students of medical information retrieval, and to provide information for medical information literacy education.MethodsWe conducted an online questionnaire survey among medical students from 15th to 21st July, 2019, aiming to analyze basic characteristics of the subjects and their ways and capability to acquire medical information, and evaluated their demands and satisfaction about relevant courses.ResultsFour hundred and nine valid questionnaires were collected. The average age of the respondents was (21±3) years old. Among the respondents, 279 (68.2%) were female, 290 (70.9%) were undergraduates, and 187 (45.7%) majored in clinical medicine. The mostly accessed ways to obtain medical information were textbooks (87.8%) and search engines (84.4%). Among Chinese literature databases, the most commonly used was China National Knowledge Infrastructure (67.7%), followed by Wanfang (54.3%). As for English literature databases, the most commonly used was PubMed (66.0%), while the proportions of respondents who used other databases was less than 1/4. As for the problems when obtaining information, 84.8% of the respondents supposed that no access to some online databases was the main problem. Obtaining information from search engine scored the highest [(3.21±1.00) points, 5 points totally] when they were asked to self-evaluate their ability to obtain medical information by different methods. In terms of training demands, the need for courses about literature authenticity and accuracy evaluation was the highest [(4.05±1.07) points, 5 points totally]. The trainings were expected to be conducted within 1-2 years after enrollment (83.9%). Training through professional courses (86.8%) was the most welcomed training form, followed by courses on MOOC (51.3%), an online course platform. More than 50% of the respondents were satisfied with the current relevant courses and trainings.ConclusionBoth the students’ capability of medical information retrieval and the design of relevant trainings should be improved to better prepare the medical students for further clinical practice and scientific research.
