Evolución e impacto bibliométrico de las becas de la Sociedad Española de Cardiología/Fundación Española del Corazón en el periodo 2007-2012

Introduction and objectivesThe Spanish Society of Cardiology/Spanish Heart Foundation (SEC/FEC) annually awards grants for cardiovascular research projects. Our objective was to analyze the trend in these investments and their resulting scientific production from 2007 to 2012.MethodsA search of the publications funded by the SEC/FEC was carried out, according to the following inclusion criteria: publication in a journal indexed in MEDLINE or EMBASE, publication date after the grant, authorship by the principal investigator of the grant, and acknowledgment of SEC/FEC funding. The impact factor and subsequent citations of the articles were analyzed (Web of Science).ResultsA total of 235 grants were awarded (39/y) with an allocation of €3 854 300 (€642 383/y), 37% of them to women. In all, 122 publications resulted from 88 research projects (37%) funded by the SEC/FEC. Up to October 2017, these publications had received 2258 citations in subsequent studies in the Web of Science, with a mean of 18.5 and a median of 8 citations/study.ConclusionsDespite the economic crisis, the mean number and size of the grants awarded by the SEC/FEC increased in the period analyzed. Grants were awarded on an equal opportunity basis to men and women. The bibliometric impact of the funded projects is acceptable, although efforts should be made to improve it.     

《中华骨科杂志》2002-2004年引文分析

目的研究《中华骨科杂志》文献引用规律及我国骨科学研究领域科研人员的文献利用与需求特征。方法利用引文计量分析法,统计《中华骨科杂志》2002-2004年间刊载的614篇论文所引用的参考文献。结果614篇论文中,有引文的论文共565篇,引文率为92.02%,篇均引文11.66条;引文中期刊6672条(93.22%),图书451条(6.30%);普赖斯指数45.44%,期刊自引361条,自引率5.04%。被引用频次居前20位的中、外文期刊的引文量占总引用期刊引文量的53.30%。结论《中华骨科杂志》涉猎文献范围广,引文类型以期刊为主,语种以英文文献为主,引文的外文语种结构较为单一,研究引用文献比较滞后,文献半衰期较长,专业人员利用近5年内新文献的能力有待于进一步提高。     

开展课外科技活动提高医学生综合素质

在高职高专医学院校专业课程教学中,开展课外科技活动是实施素质教育的有效途径.课外科技活动能够培养学生客观、求实的科学精神,严谨、认真的工作态度,勇于实践、不怕艰苦的意志品质,有助于提升学生的专业素质;课外科技活动拓宽了学生的知识面,提高了学生分析问题、解决问题的能力和实际动手操作能力,使学生掌握了科学论文的一般写作方法,有助于提高学生的职业技能;课外科技活动促进了学生对本学科前沿技术的了解,有助于学生树立热爱自然、保护环境的意识,促进学生非智力因素的发展和教师教学水平的提高,从而具有课堂教学不可替代的重要作用.     

Scientific quality of clinical research an analysis of 40 research projects in pharmacology/pharmacotherapy

Objective: The scientific quality of research is an important ethical issue. To clarify the quality of research projects in pharmacotherapy/pharmacology, 40 randomly selected research projects in pharmacotherapy/pharmacology submitted to a research ethics committee were reviewed. Results: Eight of the projects would not have contributed new knowledge nor were they necessary as controls for the results of previous research. Fifteen of the research protocols were of good quality, 15 could be used after revisions, and 10 were unfit for use. Eleven of the research projects were not finished 5 years after they were started. A written report was produced from 26 of the projects. Nine were of good quality and could be accepted for publication in a medical journal, 10 of the reports were in need of revision before publication, and 7 should not be accepted for publication. Conclusion: Research in this field ought to be improved, and ways to improve the standard of clinical trials in pharmacotherapy are dicussed.

conference report: Mental health and intellectual disability: an international perspective

The present paper reports on the inaugural meeting of the Mental Health Special Interest Research Group (SIRG) of the International Association for the Scientific study of Intellectual disability which was held at Fitzwilliam College, Cambridge, UK, in March 1998. The meeting was organized in conjunction with the Ninth Annual SIRG on ageing and intellectual disability. Representatives from North America, several European and Scandinavian countries, Australia, and Israel attended. Two broad themes had been determined prior to the meeting: ‘Improving the detection of mental health problems’ and ‘Research strategies for identifying risk factors for mental health problems’. In the presentations and subsequent discussions, it was apparent that there were extrenely diverse perspectives both across and within the different countries represented. Not only were individuals' experiences very different, but most strikingly, the theoretical frameworks were very diverse. This was partly a function of there being understandable differences in perspectives across disciplines, but at its most marked, there were fundamental differences in the way both intellectual disability and mental health were conceptualized.     

补肾方剂对去势大鼠骨代谢影响的实验研究

使用补肾方剂(补肾健骨胶囊)对切除卵巢的雌性成年大鼠进行了不同剂量的药物治疗，并与正常对照组、模型组和尼尔雌醇治疗组的大鼠进行了对比。统计学结果显示，补肾健骨腔囊治疗可有效改善卵巢切除大鼠骨质疏松症，各项骨检测指标明显好于模型组，差异有显著性和非常显著性(P＜0．05～0．001)。补肾健骨腔囊治疗后大鼠骨载荷、骨桡度、骨强度等生物力学指标明显好于模型组(P＜0．05～0．001)。说明补肾健骨胶囊治疗可明显的改善骨质疏松大鼠的骨质丢失状态，提高骨骼抵抗外力冲击的能力，有效的防治骨质琉松症，避免骨折的发生。     

Latent variable discovery in classification models

The naive Bayes model makes the often unrealistic assumption that the feature variables are mutually independent given the class variable. We interpret a violation of this assumption as an indication of the presence of latent variables, and we show how latent variables can be detected. Latent variable discovery is interesting, especially for medical applications, because it can lead to a better understanding of application domains. It can also improve classification accuracy and boost user confidence in classification models.
