Objective To learn the bibliometric characteristics of Chinese ophthalmological papers indexed in SCI database from 2007 to 2011.Methods All the ophthalmological papers published in the source journals indexed in the SCI database from 2007 to 2011 were retrieved. The papers of first authors were manually selected for bibliometric analysis.Results The ophthalmological papers published by Chinese scholars as the first author were 478, 482, 698, 791, and 1049 from 2007 to 2011 (total 3498). The five institutions that published papers in the most were Sun Yat-sen University, Capital University of Medical Sciences, Fudan University, Hong Kong Chinese University and Shanghai Jiaotong University. The papers were distributed in 625 journals. The top five journals the papers were published in were Molecular Vision (332), International Journal of Ophthalmology (268), Investigative Ophthalmology amp; Visual Science (206), Chinese Medical Journal (109), and Graefeprime;s Archive for Clinical and Experimental Ophthalmology (104). The 3498 papers were cited 12 030 times, 3.44 times per paper. The rate of non-cited articles for 5 year,3 year and 2 year periods were 12.55%, 24.21% and 38.43% respectively. Conclusions Chinese ophthalmological papers indexed in SCI database have gradually increased. Chinese ophthalmological papers mainly originate in the affiliated hospital of universities and colleges. There are four ophthalmologic professional periodicals included in the top five in the quantity of articles.
Objective To investigate the hot topics of research on evidence-based medicine in 2002. Method To search MEDLINE for papers on evidence-based medicine published in 2002, identify high-frequency subject headings related to research on evidence-based medicine, and cluster the high-frequency subject headings according to rates they appeared in common papers. Results 545 papers, 1 554 subject headings, 30 high-frequency subject headings on evidence-based medicine, and nine clustering categories of high-frequency subject headings were identified through search. Conclusions Both high-frequency subject headings and their clustering categories suggested that “evidence-based practice guidelines and their innovation”, “evidence-based health research and health policy”, “methodology on systematic reviews and randomized clinical trials”, “method of evidence-based decision making and its application in various subjects”, were the hot topics of evidence-based medicine. They provided useful references for Chinese medical professionals to practice evidence-based medicine.
ObjectiveTo analyze the papers in cardiovascular surgery field indexed by SCI-Expended between 2008 year and 2012 year from the authors in Chinese Mainland. MethodsWe searched Web of Science database(2008-2012)on-line and collected the papers on cardiovascular surgery written by the authors in Chinese Mainland. The data of publication time, type of article, journal name, and author name were recorded. ResultsA total of 427 papers in cardio-vascular surgery field were published from Chinese Mainland including 401 original articles, 10 conference papers, and 16 reviews. Although the number of papers has been increasing since 2008 year, the increase slowed down recently. Most of those authors came from few heart centers in Beijing, Guangdong, and Shanghai. Most of these papers were published in 7 journals in cardiovascular surgery field with low impact factor. ConclusionThe authors in Chinese Mainland in cardiovascular field should design more scientific research and improve academic level of paper with high quote rate.
Objective To investigate the development of biofilm research over the last 10 years in China based on a bibliometric approach. Methods We searched PubMed (1997 to 2007), China Hospital Knowledge Database (1997 to 2007), and VIP Chinese Journal Database (1997 to 2007). Quality assessment and data collection were performed by two reviewers independently. The amount of literature, research institutions, financial assistance, and contents of biofilm research were analyzed. Results A total of 240 Chinese papers were included. Colleges were the leading research institutions in China, and most of research focused on pseudomonas aeruginosa and staphylococci, primarily based on in vitro models. Available antibiotics were the main measures for biofilm control. Only 4 RCTs with a C grade in terms of methodological quality were included. Conclusion Biofilm research in China can keep pace with the international development, but its integration with engineering, material science and immunology needs to be strengthened.
ObjectivesTo conduct a bibliometric analysis to research the status of disease burden domestically and overseas so as to understand the status of diseases burden, and to provide scientific and reasonable reference for health disease prevention, control strategies formulation and future research.MethodsPubMed, Web of Science, EMbase, The Cochrane Library, WanFang Data, CBM and CNKI databases were electronically searched to collect literature on disease burden from inception to October, 2018. Two reviewers independently screened literature and extracted data. EndNote X7 software was used for literature management, Excel 2016 software and VOS viewer software were also used to analyze data. Literature was classified by the aspects of literature publication characteristics, diseases, background areas, influencing factors, evaluation indicators and poverty caused by illness.ResultsA total of 325 studies were included in the bibliometric analysis. 41 articles (12.6%) were published in journals indexed by SCIE; original research evidence accounted for 97.0% (315 articles); 272 articles were from China (83.7%). The main diseases involved were malignant tumors (58 articles, 17.8%), diabetes (29 articles, 8.9%) and hypertension (24 articles, 7.4%). Factors affecting the disease burden primarily included hospitalization days (9 articles, 2.8%), complications (5 articles, 1.5%), delays in treatment (5 articles, 1.5%), and economic income (4 articles, 1.2%). Sixity-one articles (18.8%) reported poverty due to illness, and related diseases were chronic obstructive pulmonary disease (12 articles, 3.7%), hypertension (10 articles, 3.1%), diabetes (10 articles, 3.1%), malignant tumors (9 articles, 2.8%) and hepatitis B (6 articles, 1.8%).ConclusionsAt present, the disease burden research are focusing more on the burden of chronic non-communicable diseases such as malignant tumors, hypertension, diabetes, cardiovascular and cerebrovascular diseases in developing countries and regions. Medical costs vary from different diseases and treatment, different demographic characteristics of patients, and the coverage medical security of different population are the primary reasons for the " expensive in medical treatment” of current residents and the heavy burden of disease. DALY and total direct medical expenses are the main evaluation indexes of epidemiological burden and economic burden of disease, respectively. Future researches should focus on strengthening the scientific nature of study design to improve the quality of research, as well as paying more attention to diseases and aspects that are rarely involved, such as major diseases caused by poverty due to illness, comprehensive analysis of multiple diseases and aspects of health investment measurement, and comprehensively use the evaluation indicators of disease burden to strengthen the research on the comparability index of disease economic burden.
Objective To investigate the current status of esophageal cancer surgery-related researches using bibliometric methodologies and identify the trend and hotspots. Methods The Chinese and English literature was collected from Web of Science and CNKI from inception of each database to April 1, 2022. VOSviewer 1.6.18 and CiteSpace 6.1 were applied to cluster the authors, institutions, and keywords. For social network and time series analysis, Excel, GraphPad, and R 4.0.3 were used to visualize the literature on esophageal cancer surgery. Results Finally, 19 566 English literature and 19 872 Chinese literature was included. The results demonstrated that the annual publishing of both Chinese and English literature increased over time, with English literature increasing rapidly and Chinese literature maintaining an average number of above 1 000 per year from 2011 to 2019. Researches were predominantly centered in Europe, the United States, Japan, South Korea, and China. China's researches in the field of surgical treatment in esophageal cancer lacked international collaboration, which began later than East Asian countries such as Japan and South Korea and had less influence. From the keyword perspective, previous researches on surgical treatment of esophageal cancer mostly focused on surgical techniques, complications, and comprehensive perioperative therapy. Both Chinese and English literature showed that the prevalence of keywords such as minimally invasive surgery, comprehensive treatment, and clinical trials increased dramatically during the recent years, indicating that these fields may represent the future directions and research trends. Conclusion Compared to East Asia countries, such as Japan and South Korea, Chinese esophageal cancer surgery-related researches are relatively lacking. The research direction and field are similar to those in developed countries such as the United States and Europe. Future attention may be focused on minimally invasive treatment, comprehensive treatment, and clinical trials associated with surgical treatment of esophageal cancer.
Objective To analyze the hot topics and trends of medical research integrity in China and to provide references for future studies. Methods The CNKI, WanFang Data and VIP databases were searched from inception to December 2021. Data on the number of publications, journals, institutions, authors, keywords, and emergent themes were analyzed using bibliometric methods and CiteSpace software. Results A total of 324 studies were included. The results showed that the number of publications increased annually, and "Chinese Journal of Medical Science Research Management" and Peking University were the journal and institution with the most publications, respectively. The three most prolific authors published five studies each, and the publications were mainly concerned with identifying and preventing issues, in addition to education regarding medical research integrity. Conclusion Medical research integrity in China has attracted significant attention. Several leading journals in this research field have emerged; however, there is no clearly dominant research team. The depth and breadth of the research remain to be improved. It is suggested that researchers focus on the effectiveness of strategies for preventing issues, promoting the establishment of the lifelong education system and improving related rules and regulations to advance the development of medical research integrity in China.
Objective To analyze the research progress and current situation in the field of chemotherapy-induced premature ovarian failure by bibliometrics, so as to provide scientific and efficient research path for researchers. Methods All the literature on chemotherapy-induced premature ovarian failure from 2015 to 2024 was retrieved from the Web of Science Core Collection. CiteSpace and VOSviewer software were used to conduct bibliometric analyses of authors, institutions, keywords, co-cited documents, etc., and to draw the relational graphs. Results A total of 567 papers were included. The annual research output increased slightly, and the number of papers published by Chinese researchers ranked first. The 49 selected keywords were divided into 11 clusters, and the emerging keywords showed that the research hotspots in recent years focused on more in-depth mechanism studies, such as primary ovarian insufficiency and fertility preservation in premenopausal patients, which might continue to be research hotspots. Conclusions In recent years, the research heat of chemotherapy-induced premature ovarian failure has been increasing, and Chinese scholars have made outstanding contributions, however, it is necessary to further strengthen the scientific research cooperation among researchers. Fertility preservation, hormone replacement therapy, in vitro transplantation may become the hotspots of future research, and the depth and refinement of research should be further promoted on the basis of multi-center and multi-disciplinary cross.
