The returning tide: how China, the world's most populous country, is building a competitive research base

A 14-year literature survey on spine-related clinical research output by orthopedic surgeons from mainland China

BACKGROUND

In recent years, China is increasingly playing an active role in various fields of biomedical research. Many bibliometric studies have provided valuable insights to different fields of clinical studies. However, similar evaluation on spine surgery-related clinical research is still limited. We herein aimed to examine the scientific publications by orthopedic spine surgeons from mainland China within a 14-year period.

METHODS

Articles were identified in PubMed using predetermined query terms. Descriptive statistics were calculated, and T tests, Chi-squared tests, and regression analysis were conducted on the number of publications, impact factors (IFs), citations, region of the study, and associated medical subject headings (MeSHs).

RESULTS

A total of 1498 articles were identified and the annual number of publications, citations, and IFs all increased exponentially. The average IF was significantly higher in 2007 to 2013 than 2000 to 2006. Most publications were from Shanghai and Beijing and the 5 most productive administrative regions generated 70% of all publications. Analysis of associated MeSHs suggested research topics became more heterogeneous over the study period.

CONCLUSION

This was the first comprehensive evaluation on the clinical research output by orthopedic spine surgeons from mainland China. The annual number of publications and citations both increased significantly; however, research was highly concentrated in a handful of administrative regions.

Scientific Misconduct (Fraud) in Medical Writing

Scientific misconduct (fraud) in medical writing is an important and not infrequent problem for the scientific community. Although noteworthy examples of fraud surface occasionally in the media, detection of fraud in medical publishing is generally not as straightforward as one might think. National bodies on ethics in science, strict selection criteria, a robust peer-review process, careful statistical validation, and anti-plagiarism and image-fraud detection software contribute to the production of high-quality manuscripts. This article reviews the various types of fraud in medical writing, discusses the related literature, and describes tools journals implement to unmask fraud. [Orthopedics. 2018; 41(2):e176-e183].

A Comparative Study of Scientific Publications in Health Care Sciences and Services from Mainland China, Taiwan, Japan, and India (2007-2014)

In this study, we aimed to compare the quantity and quality of publications in health care sciences and services journals from the Chinese mainland, Taiwan, Japan, and India. Journals in this category of the Science Citation Index Expanded were included in the study. Scientific papers were retrieved from the Web of Science online database. Quality was measured according to impact factor, citation of articles, number of articles published in top 10 journals, and the 10 most popular journals by country (area). In the field of health care sciences and services, the annual incremental rates of scientific articles published from 2007 to 2014 were higher than rates of published scientific articles in all fields. Researchers from the Chinese mainland published the most original articles and reviews and had the highest accumulated impact factors, highest total article citations, and highest average citation. Publications from India had the highest average impact factor. In the field of health care sciences and services, China has made remarkable progress during the past eight years in the annual number and percentage of scientific publications. Yet, there is room for improvement in the quantity and quality of such articles.

Comparative study of scientific publications in orthopedics journals originating from USA, Japan and China (2000-2012)

PURPOSE

To compare orthopedics publications from USA, Japan and China.

METHODS

Scientific papers belong to ''Orthopedics'' category of Science Citation Index Expanded subject categories were retrieved from the "PubMed'' and ''Web of Knowledge'' online databases.

RESULTS

In the field of orthopedics, the annual number increased significantly from 2000 to 2012 in the three countries (p<0.001). The share of articles increased significantly in China, but decreased significantly in Japan and USA (p<0.05). In 2012, USA contributed 35.3% of the total world output in orthopedics field and ranked 1st; Japan contributed 5.9% and ranked 4th; China contributed 5.2% and ranked 5th. Publications from USA had the highest accumulated IFs and the highest total citations of articles (USA > Japan > China, p<0.001). Average IF from USA was much higher than Japan and China (p<0.001). USA published the most articles in the top ten orthopedics journals (USA (14355) > Japan (1702) > China (487), p<0.01).

CONCLUSION

Although China has undergone significant increase in annual number and percentage of scientific publication in orthopedics journals, it still lags far behind USA and Japan in the field of orthopedics in terms of quantity and quality.

The Human Proteome and the Chinese Liver

The Human Liver Proteome Project (HLPP) is the largest international scientific research project ever headquartered in China. At the same time, the HLPP is one component of the global Human Proteome Project (HPP), which in 2001–2002 began dividing the organs and systems of the human body between different national laboratories and institutes. Research on the kidney was assigned to Japan, brain research to Germany, liver research to China, etc. Only in China, however, did the project take on the character of ‘big science’, successfully competing with other scientific initiatives for funding and prestige at the highest level, and developing ‘national’ characteristics similar to that of genomics research in the United States. Our article considers this flagship Chinese bioscience project from two complementary angles: as ‘big science’ at the cutting edge of biomedical research, and as a discursive and practice-oriented meeting ground between modern and ‘traditional’ Chinese medicine. We also discuss how these strands are politically and philosophically convergent.

Scientific publications in ophthalmic journals from China and other top-ranking countries: a 12-year review of the literature

Background

Eye diseases with increasing mortality are common health problems that affect people of all ages and demographic backgrounds. In this study, we study the publication characteristics in international ophthalmic journals of the US, the UK, Germany, Australia, Japan, and China.

Methods

Articles published in 53 ophthalmic journals from 2000 to 2011 were retrieved from the PubMed database. We recorded the number of articles published each year, analyzed the publication type, and evaluated the accumulated and average impact factors (IFs), and the distribution of articles in ophthalmic journals in relation to IFs. The characteristics of publication outputs from China and other top-ranking countries were compared.

Results

The total number of articles increased significantly during the past 12 years, with an increase of 51.0%. The growth in the annual number of articles from the US, the UK, Australia, and China showed a significantly positive trend. Publications from the US exceeded those from any other country and had the highest IFs, largest number of total citations of articles, and the most articles published in leading ophthalmic journals. During the past 12 years, China contributed 3.5% of the total publications, and the number of Chinese articles showed a more than 6-fold increase (from 99 to 605, R2 =0.947, P<0.001). The numbers of IFs and citations of articles originating in China were mostly lower than for other top-ranking counties.

Conclusions

Research on ophthalmic journals has maintained an upward growing trend from 2000 to 2011. Chinese ophthalmology research has developed rapidly, but the gap still exists between China and other top-ranking countries for the advanced level of research.

Comparative study of scientific publications in urology and nephrology journals originating from USA, China and Japan (2001-2010)

Background

In the past decade, scientific research has developed rapidly in China, but the growth seems to vary widely between different disciplines. In this study, we aimed to compare the quantity and quality of publications in urology and nephrology journals from USA, China and Japan.

Methods

Journals listed in the “Urology and Nephrology” category of Science Citation Index Expanded subject categories were included. Scientific papers in these journals written by researchers from USA, Japan and China were retrieved from the “PubMed” and “Web of Knowledge” online databases.

Results

The annual number of total scientific articles increased significantly from 2001 to 2010 in China, and has ranked second in the world since 2006. In the field of urology and nephrology, the annual number increased significantly from 2001 to 2010 in USA and China; but not in Japan. The share of articles increased significantly over time in China, decreased significantly in Japan, and remained unchanged in USA. In 2010, USA contributed 32.17% of the total world output in urology and nephrology field and ranked 1^st; Japan contributed 5.19% and ranked 5^th; China contributed 3.83% and ranked 9^th. Publications from USA had the highest accumulated IFs and the highest total citations of articles (USA>Japan>China, p<0.001). No significant difference was found in average IF among the three countries. USA published the most articles in the top 10 urology and nephrology journals (USA(35165)>Japan(6704)>China(2233), p<0.001). Researchers from USA published more clinical trials and randomized controlled trials than Japan and China (USA>Japan>China, p<0.001).

Conclusion

Although China has undergone significant increase in annual number and percentage of scientific publication in urology and nephrology journals in the past decade, it still lags far behind USA and Japan in the field of urology and nephrology in terms of quantity and quality.

Scientific publications in urology and nephrology journals from China: A 10-year analysis

BACKGROUND

The scientific research in urology and nephrology of China has developed significantly. The present study was designed to analyze the outputs of publications in urology and nephrology journals from three regions of China: mainland, Taiwan and Hong Kong.

METHODS

The numbers of articles, impact factors, citation reports and other indexes within this category between 2000 and 2009 were extracted for quantity and quality comparisons from PubMed and the ISI (Institute for Scientific Information-currently called the Thomson Reuters Web of Knowledge) database.

RESULTS

There were 3100 articles from the mainland (36.5%), Taiwan (46.8%) and Hong Kong (16.7%), and the increasing trend in each region was significant (p < 0.001). The accumulated impact factor and total citation of Taiwan exceeded the other two regions, while the average impact factor and citation of Hong Kong was highest. There were differences between the three regions on the most popular journals.

INTERPRETATION

Although the quantity of articles in urology and nephrology from the mainland has exceeded Taiwan and Hong Kong since 2008, there is a considerable gap in the quality of articles between the mainland and the other two regions.

Clinical research promotes development of nephrology in China: an analysis of 20 years of scientific publications

BACKGROUND

To study the trend of clinical and basic research output in the field of nephrology in China during the past 20 years.

METHODS

The journals listed in the "Urology and Nephrology" category of Science Citation Index Expanded (SCIE) subject categories were selected. The papers were retrieved by searching the PubMed database. Mainland China (ML), Hong Kong (HK), and Taiwan (TW) were chosen as investigative regions compared with other developed countries. Geographical difference in publications in ML was analyzed. The change between clinical and basic research papers was compared. The accumulated or average impact factor (IF) and the number of papers published in the 10 most impacted journals were calculated to determine the quality of papers.

RESULTS

The research output in the field of nephrology in ML developed markedly in the last 7 years (an average annual increase of 54% from 2004); ML exceeded TW and HK since 2008. The research output born in ML was mainly from five cities, for example, Beijing, Shanghai, Nanjing, Guangzhou, and Hangzhou, which accounted for 72% of the total. Since 2001, clinical research papers increased yearly by 11.55, and the basic research papers increased by 4.55. However, clinical trials were still limited. In 2010, ML had the highest accumulated IF and the lowest average IF. ML had the second highest number of publications in the 10 top-ranking nephrology journals among the three regions.

CONCLUSIONS

China has made a remarkable progress in the field of nephrology. Clinical researches have promoted the development of nephrology. The quality of research papers in China needs further improvement.

Growing Trend of China’s Contribution to the Field of Rheumatology 2000–2009: A Survey of Chinese Rheumatology Research

Objective.

In the past decade, rheumatology in China has achieved great advances. However, scientific publications on rheumatology in the 3 major regions of China — Mainland (ML), Hong Kong (HK), and Taiwan (TW) — are unknown. We assessed the performance of rheumatology research in China from 2000 to 2009.

Methods.

Twenty-two journals included in the rheumatology category of the Journal Citation Reports database were selected. We analyzed the following measures for 2000–2009: (1) total number of articles originating from ML, HK, and TW; (2) impact factor (IF) of those articles; (3) total number of citations and average number of citations per article; and (4) number of articles about clinical trials, randomized controlled trials (RCT), and case reports. We also noted the total number of articles from the 3 regions published in 10 top-ranking journals.

Results.

There were 788 articles for the 3 regions of China, including 259 from ML, 372 from TW, and 157 from HK, with a positive trend between the years 2000 to 2009. From 2006 on, published articles from ML exceeded those from HK, and in 2008, published articles from ML exceeded those from TW. HK had the highest average IF and highest average citations of each article compared with articles from ML and TW. TW published the most RCT, clinical trials, and case reports, as well as the most articles in the 10 top-ranking journals in the last decade, followed by ML and HK.

Conclusion.

Chinese contributions to the field of rheumatology have increased rapidly since 2000, particularly from ML. HK had the highest quality research output according to average IF and average citations per article.

Pathological research output in China and other top-ranking countries: 10-year survey of the literature

The present study was designed to study the research output in pathology journals from the United States (USA), Japan, Germany, the United Kingdom (UK), France, and China between 2000 and 2009. Articles published in 67 pathology-related journals were retrieved from the PubMed database. US-American publications, which rank first, accounted for 30.9% of the total world's output and for 35.4% in the top 10% journals with impact factor (IF) scores. Chinese publications accounted for 2.8% of a total of 67 journals, and for 2.0% in the top 10% journals with IF scores. Our analysis investigated the research output of these six countries and revealed a positive trend in China for the period 2000-2009. Also, in contrast to other top-ranking countries, our results imply that China's research in the field of pathology falls behind that of the developed countries, and appropriate steps should be taken to improve the role of pathologists in clinical activity and to gear up for high-quality pathological studies.

Publication in infectious diseases journals from Chinese authors: 10-year survey of literature

China is a major contributor to the worldwide infectious diseases burden because of its population size. However, to-date little is known about China's contribution to the field of infectious diseases. The present study was designed to determine publication in infectious diseases journals during 1999-2008 in the 3 main regions of China--the Mainland (ML), Hong Kong (HK) and Taiwan (TW). Articles published in 51 journals related to infectious diseases were retrieved from the PubMed database. The total number of articles, impact factor (IF), and articles published in the top 10 infectious diseases journals were identified. The numbers and percentages of articles showed significantly positive trends in ML and TW. From 2005 onwards, the accumulated IF from ML exceeded that from HK, and in 2007 ML exceeded TW. Our analysis determines the research output in the infectious diseases research field of the 3 main regions of China. Also, the results of this study imply that China lags behind the developed countries in conducting infectious diseases research.

New Horizons for the Next Era of Human Brain Imaging, Cognitive, and Behavioral Research: Pacific Rim Interactivity

Beginning in the 1990's, substantial advances have been made in the ability to image the living human brain. Functional MRI, PET, and other modalities have been developed to provide a rich means for assessing brain function and structure across spatial and temporal dimensions. Such methods are now the preferred means to examine the brain in vivo, with several thousand articles now appearing in the literature each year. The next era of human brain imaging is upon us now as technological developments reach a level where data can be processed quickly and combined with other biological information to provide fundamentally new applications and insights. This new era will involve and require the collaborative participation of leading research groups from around the world to share information and expertise for understanding observed effects and synthesizing these into new knowledge. One particular community that is gaining in its prominence in the field is that of the Pacific Rim, whose collective research efforts present an important corpus of research effort into brain structure and function. The Pacific Rim represents an important collection of researchers interested in the greater sharing of ideas. In this special issue of Brain Imaging and Behavior, we focus on emerging areas of research that utilize brain imaging methodology, and discuss how current developments are driving the expansion of functional imaging research. Moreover, we focus on the robust interaction of researchers from around the Pacific Rim whose collaborations are significantly shaping the future of brain imaging.
