【摘要】 目的了解2007～2016年全球五大生物医学期刊中中国学者所发表的科研论文现状,评估中国学者在国际上的科研能力水平及时间变化趋势。方法检索PubMed数据库NEJM、JAMA、BMJ、Lancet和PLoS Medicine 5本期刊上2007～2016年中国学者发表的所有研究,按《国际疾病分类》第10版(ICD-10)对发表文献涉及的疾病分类,定量分析作者单位、研究类型、发表数量及趋势。结果中国学者在Lancet发表文献量居5种期刊首位(56.4%)。疾病分类方面,传染和寄生虫病、循环系统疾病、肿瘤、内分泌、营养和代谢疾病及神经精神类疾病居前五,占总文献量的38.4%;在不同研究类型中,综述类非实验性研究占比最高,随机对照试验排第二。结论中国学者在生物医学5大刊发表排名前五的疾病种类为传染病和寄生虫病、循环系统疾病、肿瘤、内分泌、营养和代谢疾病及神经精神类疾病,以综述、随机对照试验为主要研究类型。更多还原

【Abstract】 Objectives To evaluate the level and variation of Chinese scholars’ scientific research capability in the world by analysing the status of literature published on top-five global biomedicine journals by Chinese scholars in the past 10 years. Methods Literature published on NEJM, JAMA, BMJ, Lancet and PLoS Medicine from 2007 to 2016 were searched in PubMed database. Types of diseases were classified by using International Classification of Diseases(version10)(ICD-10). Quantitatively analysis were used to classify the different authors, institutes, studies designs, quality of publication and variation. Results Literature(56.4%) published on Lancet had the largest quantity among the top-five journals. Infectious and parasitic diseases, circulation system diseases, cancers, endocrine, nutrition and metabolic diseases and neuropsychiatric diseases were the top-five in disease categories list, accounting for 38.4%. In different study design,reviews(non-experimental research) and randomized controlled trials were the first and the second study types,separately. Conclusions For productivity of Chinese scholars’ diseases publications on top-five medical journals, the top-five specific diseases are from the top-five disease categories-infectious and parasitic diseases, circulation system diseases, cancer, endocrine, nutrition and metabolic diseases and neuropsychiatric diseases. The main study types are reviews, randomized controlled trials and cross-sectional studies.更多还原
