Quality assessment of paediatric randomized controlled trials published in China from 1999 to 2022: a cross-sectional study

BackgroundRandomized controlled trials (RCTs) are usually the basis of evidence-based medicine, but whether the results of RCTs can be correctly translated into clinical practice depends on the quality of the literature reported. In this study, we evaluated the general characteristics and quality of paediatric RCTs published in China to provide evidence for the reporting of paediatric RCTs and their application in clinical practice.MethodsWe conducted a cross-sectional observational study of paediatric RCTs published in paediatric journals in China between January 1, 1999, and December 30, 2022. All RCTs that included children (younger than 18 years old) were retrieved, and the general characteristics of the RCTs were extracted and analysed. The quality of the RCTs was assessed by the Cochrane quality assessment protocol.ResultsAfter screening 20 available paediatric journals, 3545 RCTs were included for analysis. The average annual growth rate of the number of published paediatric RCTs from 1999 to 2022 was 7.8% (P = 0.005, R2 = 0.311). Most of the studies were carried out in East China [1148 (32.4%]; the centres of the RCTs were mainly single-centre [3453 (97.4%], and the interventions were mainly medication [2442 (68.9%)]. Comparing RCTs published in 2017–2022 with RCTs published in 1999–2004, the quality of RCTs significantly improved in terms of random sequence generation, allocation concealment, blinding participants and personnel, incomplete outcome data and selective outcome reporting. RCTs published in multiple centres from the Chinese Science Citation Database were identified, and the approval of the ethics committee was of better quality for all the analysed risk of bias items.ConclusionThe number and quality of paediatric RCTs reported in China have improved in recent years, but the overall quality was relatively low. Special attention should be given to allocation concealment and blinding outcome assessment, and dropouts, adverse effects and sample size calculations should be reported. Promoting government policies, strengthening the standardization of journal publishing and advancing the registration of clinical trials are feasible measures.

A systematic review and meta-analysis on sodium tanshinone IIA sulfonate injection for the adjunctive therapy of pulmonary heart disease

AimsSodium tanshinone IIA sulfonate (STS) injection has been widely used as adjunctive therapy for pulmonary heart disease (PHD) in China. Nevertheless, the efficacy of STS injection has not been systematically evaluated so far. Hence, the efficacy of STS injection as adjunctive therapy for PHD was explored in this study.MethodsRandomized controlled trials (RCTs) were screened from China Science and Technology Journal Database, China National Knowledge Infrastructure, Wanfang Database, PubMed, Sino-Med, Google Scholar, Medline, Chinese Biomedical Literature Database, Cochrane Library, Embase and Chinese Science Citation Database until 20 January 2024. Literature searching, data collection and quality assessment were independently performed by two investigators. The extracted data was analyzed with RevMan 5.4 and STATA 14.0. Basing on the methodological quality, dosage of STS injection, control group measures and intervention time, sensitivity analysis and subgroup analysis were performed.Results19 RCTs with 1739 patients were included in this study. Results showed that as adjunctive therapy, STS injection combined with Western medicine showed better therapeutic efficacy than Western medicine alone for PHD by increasing the clinical effective rate (RR = 1.22; 95% CI, 1.17 to 1.27; p < 0.001), partial pressure of oxygen (MD = 10.16; 95% CI, 5.07 to 15.24; p < 0.001), left ventricular ejection fraction (MD = 8.66; 95% CI, 6.14 to 11.18; p < 0.001) and stroke volume (MD = 13.10; 95% CI, 11.83 to 14.38; p < 0.001), meanwhile decreasing the low shear blood viscosity (MD = -1.16; 95% CI, -1.57 to -0.74; p < 0.001), high shear blood viscosity (MD = -0.64; 95% CI, -0.86 to -0.42; p < 0.001), plasma viscosity (MD = -0.23; 95% CI, -0.30 to -0.17; p < 0.001), hematokrit (MD = -8.52; 95% CI, -11.06 to -5.98; p < 0.001), fibrinogen (MD = -0.62; 95% CI, -0.87 to -0.37; p < 0.001) and partial pressure of carbon dioxide (MD = -8.56; 95% CI, -12.09 to -5.02; p < 0.001).ConclusionSTS injection as adjunctive therapy seemed to be more effective than Western medicine alone for PHD. However, due to low quality of the included RCTs, more well-designed RCTs were necessary to verify the efficacy of STS injection.

Establishment and implementation of a clinical application and research database for surgical robots in China

AbstractRobots are widely used in surgeries worldwide. To improve robotic surgical treatments, we established a database of clinical applications and research on surgical robots. Robotics‐related literature included in the China national knowledge infrastructure (CNKI), Wanfang, Vipshop, Chinese science citation database (CSCD), Web of Science, EMBASE, PubMed, and Cochrane databases up to September 2022 was searched and entered into the database. Information on all patients who had undergone robotic surgery at our hospital since 2016 was also included. Literature and case information was classified and evaluated according to standard guidelines and statements. The Gansu Provincial Hospital was the first to use evidence‐based medical research methods to successfully establish a database of clinical applications and research on surgical robots. This database comprised literature search, upload, quality evaluation, risk of bias assessment, case information entry, and access functions. Based on the database, we conducted related studies in general surgery, gynecology, urology, thoracic surgery, and cardiovascular surgery, and published 16 meta‐analyses and 15 clinical studies. Establishing this database removes language, retrieval, and evaluation barriers in clinicians' use of clinical evidence and lays the foundation for the efficient and accurate use of clinical data for future research. Further, it facilitates evidence‐based evaluation of the effectiveness of robotic therapy, which may guide future medical practice. This typical case of interdisciplinary research aims to build a platform to disseminate knowledge and technology in robotic surgery.This article is categorized under: Technologies &gt; Computer Architectures for Data Mining Application Areas &gt; Data Mining Software Tools Application Areas &gt; Education and Learning

A bibliometric analysis of research trends and hotspots in alpine grassland degradation on the Qinghai-Tibet Plateau.

A bibliometric analysis of current research, hotspots, and development trends was used to develop an overall framework of mechanisms of alpine grassland degradation on the Qinghai-Tibet Plateau. This investigation includes data from 1,330 articles on alpine grassland degradation on the Qinghai-Tibet Plateau, acquired from the Chinese Science Citation Database (CSCD) and Web of Science Core Collection (WOS). Research was divided into three themes: spatial scope and management of typical grassland degradation problems, dynamic mechanisms of grassland degradation and effects of ecological engineering, and grassland degradation risk based on remote sensing technology. The results of the analysis showed that the research can be summarized into three aspects: typical grassland degradation identification, dynamic mechanism analysis of grassland degradation, and grassland ecosystem stability strategy. The main findings can summarized, as follows: (1) Ecological analyses using the river source as a typical region defined the formation of "black soil beach" type degraded grasslands in the region, and promoted the ecological environment management and protection of the alpine grassland by discussing the causes of regional ecological environment changes; (2) Dynamic mechanism analyses of climate change and characteristics analyses of grassland vegetation-soil degradation revealed that alpine grassland degradation is the result of multiple main factors; and (3) Risk prediction methods for grassland degradation, methods of grassland management and sustainable countermeasures for agriculture and animal husbandry development, and the development of a comprehensive index of influencing factors on grassland degradation all indicate that selecting the right grassland restoration measures is the key to grassland restoration. Remote sensing monitoring and high-throughput sequencing technology should be used in future research on grassland ecosystems. In addition, multiscale, multidimensional, and multidisciplinary systematic research methods and long-term series data mining could help identify the characteristics and causes of alpine grassland system degradation. These findings can help identify a more effective coordination of landscape, water, lake, field, forest, grass, and sand management for the prevention of alpine grassland degradation.

Occupational Health and Safety in China: A Systematic Analysis of Research Trends and Future Perspectives

The frequent occurrence of various occupational accidents has resulted in significant casualties and occupational disease issues, which hinder economic and social development seriously. The promotion and enhancement of occupational health and safety (OHS) require greater efforts to be made to achieve sustainable economic development, particularly in developing countries. With remarkable progress and achievements that have been made in terms of OHS in China, a systematic and thorough review is needed to gain insight into the development process, current status, and research trends regarding OHS in China. Additionally, pathways for future work need to be discussed to boost the OHS development in China in the new era. Therefore, a systematic literature review is performed in this study to investigate the development of OHS in China with the help of a bibliometric analysis. Firstly, a total of 5675 publications related to OHS in China between 1979 and 2022 were collected from the Web of Science Core Collection (WoSCC) and the Chinese Science Citation Database (CSCD) before being refined manually. Then, the temporal distribution and journal sources of the collected publications were analyzed before the collaboration networks of the “productive institutions” and “productive authors” were discussed. Furthermore, the key research topics (e.g., disease prevention, psychological safety, occupational exposure) and dominant research methods (e.g., epidemiological methods, risk modeling) associated with OHS during different periods were identified and discussed based on the keywords and bibliographic analysis. Finally, the current needs and promising pathways for future work were discussed. It is suggested that the prevention and control of conventional and new occupational diseases, the protection of workers’ occupational health rights and interests, the development and implementation of advanced technologies for OHS, and the development of more sophisticated and efficient health and safety risk assessment models may be focused on to accelerate the development of OHS in China. This study systematically reviews the development processes, current status, and future prospects regarding OHS in China. The results of this study provide valuable insights for researchers and practitioners who are involved in the Chinese OHS development, and the promising pathways for future works are suggested to boost the OHS development in China.

Prevalence of hypertension among type 2 diabetes mellitus patients in China: a systematic review and meta-analysis.

This study aimed to estimate the prevalence of hypertension in Chinese patients with type 2 diabetes mellitus (T2DM) using the results of a regional study. The studies were reviewed using PubMed, EMBASE, Web of Science, the Cochrane Library, China National Knowledge Infrastructure, China Biology Medicine, Wan Fang Data and Chinese Science Citation Database. After screening articles and data extraction, Stata V.16 was used for statistical analysis. This study was registered in the Prospective Register Systematic Reviews (CRD42020170649). A total of 2126 articles were identified, and nine papers were finally included. Random-effects modelling showed that the pooled prevalence of hypertension among Chinese patients with T2DM was 54% (95% CI 47 to 61%). Subgroup analysis showed that the prevalence in men (59.8%; 95% CI 49.0 to 70.7%) was higher than that in women (40.2%; 95% CI 29.3 to 59.2%). The prevalence in North China was higher than that in East China. The prevalence in institution-based settings (56%; 95% CI 48 to 64%) was higher than that in community-based settings (51%; 95% CI 34 to 69%). Appropriate preventive measures should be undertaken, such as health education, to control and reduce the risk of hypertension in diabetic patients and reduce the burden of cardiovascular disease.

Efficacy and effectiveness of inactivated vaccines against symptomatic COVID-19, severe COVID-19, and COVID-19 clinical outcomes in the general population: a systematic review and meta-analysis

Inactivated, whole-virion vaccines have been used extensively in the SARS-CoV-2 pandemic. Its efficacy and effectiveness across regions have not been systematically evaluated. Efficacy refers to how well a vaccine performs in a controlled environment. Effectiveness refers to how well it performs in real world settings. This systematic review and meta-analysis reviewed published, peer-reviewed evidence on all WHO-approved inactivated vaccines and evaluated their efficacy and effectiveness against SARS-CoV-2 infection, symptomatic infection, severe clinical outcomes, and severe COVID-19. We searched Pubmed (including MEDLINE), EMBASE (via OVID), Web of Science Core Collection, Web of Science Chinese Science Citation Database, and Clinicaltrials.gov. The final pool included 28 studies representing over 32 million individuals reporting efficacy or effectiveness estimates of complete vaccination using any approved inactivated vaccine between January 1, 2019 and June 27, 2022. Evidence was found for efficacy and effectiveness against symptomatic infection (OR 0.21, 95% CI 0.16-0.27, I2=28% and OR 0.32, 95% CI 0.16-0.64, I2=98%, respectively) and infection (OR 0.53, 95% CI 0.49-0.57, I2=90% and OR 0.31, 95% CI 0.24-0.41, I2=0%, respectively) for early SARS-CoV-2 variants of concern (VoCs) (Alpha, Delta), and for waning of vaccine effectiveness with more recent VoCs (Gamma, Omicron). Effectiveness remained robust against COVID-related ICU admission (OR 0.21, 95% CI 0.04-1.08, I2=99%) and death (OR 0.08, 95% CI 0.00-2.02, I2=96%), although effectiveness estimates against hospitalization (OR 0.44, 95% CI 0.37-0.53, I2=0%) were inconsistent. This study showed evidence of efficacy and effectiveness of inactivated vaccines for all outcomes, although inconsistent reporting of key study parameters, high heterogeneity of observational studies, and the small number of studies of particular designs for most outcomes undermined the reliability of the findings. Findings highlight the need for additional research to address these limitations so that more definitive conclusions can be drawn to inform SARS-CoV-2 vaccine development and vaccination policies.

Current status and frontier tracking of the China HACCP system.

In today's booming society and in the age of science and technology, the diversification of food processing methods, the continuous extension of the food trade chain, and the potential hazard factors in the food production process all make people pay more and more attention to the establishment, development, and improvement of the hazard analysis and critical control points (HACCP) system. Only terminal control and post-processing supervision of food can guarantee the absolute safety of food. In the process of processing, it is particularly important to strictly identify and evaluate the food safety hazards. To better assist food production enterprises in establishing and implementing HACCP systems, to implement the primary responsibility of food safety, and to improve the theoretical level and practical application of HACCP system in China, an investigation of the current situation and development frontier of HACCP system in China was conducted. Based on the core journal database of China Knowledge Network, the Chinese Social Science Citation Index database, and the Chinese Science Citation Database as the literature search database platform, the study used the CiteSpace visual metrics software system to analyze 1,084 pieces of literature in the field of HACCP research, in order to track the dynamics and impact of research in this field by Chinese research institutions and major authors, and analyze the research hotspots in the field. It is important for further research on HACCP. The results of the study showed that (1) the number of publications in the field of HACCP in China increased steadily from 1992 to 2004 and then began to decrease; (2) the indexes of journals with more publications were more concentrated, and the journal Food Science published the most; (3) the indexes of major research institutions showed that the cultivation bases of the State Key Laboratory of Chinese Medicinal Materials in the Center of Chinese Medicine Resources of the Chinese Academy of Traditional Medicine, the Guangdong Institute of Occupational Diseases, the Nanchang University of Life Sciences, and the Guangdong Institute of Occupational Diseases were more concentrated. Prevention and Treatment Institute, School of Life Sciences of Nanchang University, China Aquatic Products Quality Certification Center, School of Food Science and Nutrition Engineering of China Agricultural University, and other research structures have the most publications and strong scientific research strength; (4) from the main author indicators, the research in the field of HACCP has formed a total of four more active research teams, involving Chinese herbal medicine, ecological planting, ecological agriculture, occupational disease prevention and treatment, light industry handicrafts, computer software and computer application, agricultural economy, and other research directions. The cooperation between the authors of each team is closer. It is suggested that in terms of food safety requirements, China should not only integrate the traditional supervision measures for food terminals and after the event but also reflect the role of food hazard analysis and assessment in the production process and comprehensively integrate the pre-production, production, and post-production management of food so that food can really be safe.

Towards the Armenian Science Citation Index

Evaluation of scientific productivity and output can be a challenge, especially for developing countries, as national or regional publications are often poorly covered by the international databases. To address this issue, policymakers adopt new instruments and mechanisms to evaluate local and international publications. A number of countries have developed national and regional indexes such as the Chinese Science Citation Database or SciELO, which started in Brazil, and is now covering most South American national output, Spain, and South Africa. In Armenia, the task to build a platform for the Armenian Science Citation Index (ASCI) has been undertaken by the Center for Scientific Information Analysis and Monitoring of the Institute of Informatics and Automation Problems of the National Academy of Sciences to evaluate the scientific output of Armenian researchers, scientific groups, laboratories, and organizations and help develop Armenian journals. We have provisional arrangements in place and intend to have all local Armenian scientific journals included in ASCI. We also plan to cover the publications of Armenian authors published abroad. Our end goal is to establish cooperation with international open scientific databases and exchange information with them. According to our ongoing research, Armenian scientific journals receive a lot of citations abroad and exchange will highly contribute to further international visibility of Armenian scientific journals.This paper presents the future centralized ASCI platform that will include local and international publications and the tools it will employ to analyse and evaluate institutional output, with a few specific examples. Thanks to the NI4OS project funded by EC Horizon 2020, the platform will provide services to interested researchers based on the FAIR principles and eventually be integrated with international scientific databases.

Review of Research on Road Traffic Operation Risk Prevention and Control.

Road traffic safety can be ensured by preventing and controlling the potential risks in road traffic operations. The relevant literature was systematically reviewed to identify the research context and status quo in the road traffic operation risk prevention and control field and identify the key study contents needing further research. As research material, the related English and Chinese literature published between 1996 and 2021 (as of 31st December 2021) was obtained through the Web of Science Core Collection and Chinese Science Citation Database. These research materials include 22,403 English and 7876 Chinese papers. Based on the bibliometrics, this study used CiteSpace software to conduct keyword co-occurrence analysis in the field. The results show that the relevant research topics mainly covered the risks of drivers, vehicles, roads, and the traffic environment. In the aspect of driver risks, the studies focused on driving behavior characteristics. In terms of vehicle risks, the related studies were mainly about the vehicle control system, driving assistance system, hazardous material transportation, automated driving technology, safe driving speed, and vehicle collision prediction. For the road risks, the safe driving guarantee of high-risk road sections, driving risks at intersections, and safe road alignment design were the three study hotspots. In terms of traffic environment risks, identifying traffic risk locations and driving safety guarantees under adverse weather conditions were the two main research highlights. Moreover, mathematical modeling was the main method for studying road traffic operation risk. Furthermore, the impact of environmental factors on drivers, the emergency rescue system for road traffic accidents, the connection between automated driving technology and safe driving theory, and the man–machine hybrid traffic flow characteristics are the subjects needing further research.

China Carbon Neutralization Research Status and Research Frontier Tracking

In the context of global joint response to climate change, carbon neutralization has become one of the main measures for governments, enterprises, and even individuals around the world to deal with global warming. This article explores the current research status and frontier trends in the field of carbon neutralization, which can not only provide theoretical reference for the follow-up research of carbon neutralization but also provide useful ideas for the policy-making of carbon neutralization. The study is built on the China National Knowledge Infrastructure (CNKI) Core Journals Database, the Chinese Social Sciences Citation Index database, and the Chinese Science Citation Database as the literature retrieval database platform. Using CiteSpace optical measurement software, 370 pieces of literature in the field of carbon neutrality research in China were systematically analyzed to track the situation and impact of research by various research institutions and prominent authors in China in this field and to analyze the research hotspots in this field, which is of great significance for the follow-up research of carbon neutrality. The research results show that 1) the number of publications in China’s carbon-neutral field has increased significantly with the change of years and has strong development potential. 2) Journals with many articles are more concentrated and are generally published in three journals: Natural Gas Industry, Proceedings of the CSEE, and Chinese Science Bulletin. 3) In terms of the major research institutions, the Institute of National Conditions of Tsinghua University, the School of Public Administration of Tsinghua University, the School of Grammar of Beijing University of Technology, and the Economic Development Research Center of the State Forestry and Grassland Administration have published more articles and muscular scientific research strength in the field of carbon neutrality. 4) In terms of the principal authors, four typical research teams have been set up: low-carbon economy, low-carbon cycle, carbon trading, sewage carbon neutrality, environmental science, and resource utilization, and the authors of each research team cooperate closely. 5) In the future, the research hotspots in China’s carbon-neutral field are still the themes of carbon emission reduction, green and low carbon, new energy, etc., and the research hotspots have begun to shift to the concept of development, from the very beginning of environmental protection and carbon emission reduction to the current new energy development. Carbon neutrality is currently a hot research field in China, and in the future, special attention should be paid to the full use of machine learning and extensive data mining to solve complex social, economic, and ecological problems. It is suggested that China should introduce the concepts of “common but differentiated responsibilities” and “consumer responsibility” in the international climate change negotiations in the formulation of carbon neutralization policies, so as to fully protect the right to the development of China’s underdeveloped regions and avoid the injustice caused by the blind formulation of carbon neutralization policies.Systematic Review Registration: [https://review.frontiersin.org/review/896524/16/1295417/#tab/History]

Factors affect the housing prices in China: a systematic review of papers indexed in Chinese Science Citation Database

PurposeThis paper aims to explore the factors that affect housing prices as per Chinese articles indexed in the Chinese Science Citation Database (CSCD). There were different foci regarding what drove housing prices in China in Chinese articles, and international journal articles in English. As most previous English articles only threw light on international research, it motivated the researchers to systematically review Chinese literature’s factors that affected housing prices in China.Design/methodology/approachThis paper reviewed housing price research articles indexed in the two largest Chinese academic research databases: the CSCD and China Knowledge Infrastructure Engineering Database (CNKI.NET). It systematically collected the data and adopted descriptive analysis techniques and synthesis.FindingsThis research reviewed the literature published from 2015 to 2020 and revealed some unique factors affecting China's housing prices. For example, research focused on administrative aspects such as macroeconomic regulation and control (often known as macro control). Authors of Chinese articles suggested that the two-child policy affected housing prices, which differed from that in the English journal articles. The research results implied that researchers should read top Chinese journals on top of good international journals when they study China's real estate market in the future.Research limitations/implicationsBecause the domestic real estate market started late, domestic real estate transaction data and real estate-related statistics are more difficult to obtain. The research is mostly based on the relationship between supply and demand, government policy and individual consumer factors, and the sample has a short time span.Practical implicationsAs China is a planned economy country, administrative factors are one main factor that affects the housing price. There were a significant number of articles in Chinese that considered this factor to be the main driver of the real estate price. It included government investment and macro-control, i.e. direct government intervention to cool down the overheated economy. Yet, there are few English articles that threw light on this factor including the commodity housing supply and government behaviour that affect housing price. The second-child policy, which is unique in China, also played an important role in the determination of the housing price. In the articles indexed in CNKI, the second-child rate, willingness to have a second child or having a second child were mentioned in the Chinese articles but not the English ones.Social implicationsIn this paper, the economic, social, administrative and environmental factors were summarised, which basically covered all the factors affecting housing prices. The administrative factors were a special group of factors that affect the housing price because of the country's planned economic system. Secondly, it provided useful information to real estate development enterprises in China. To make a correct investment and management decision, real estate development enterprises must understand the actual situation and possible problems of the industry. In this study, we analysed the research literature on the real estate industry in China for the period from 2015 to 2020 one by one and determined the influencing factors of the housing price, which provided references for effective cost control. Thirdly, it allows the public to understand and grasp the real estate industry. As the housing price has been continuously increasing, the public pays increasing attention to the real estate industry. Through the literature analysis of the impact of real estate prices, this paper revealed the elements of house price expenses, which makes it convenient for ordinary people to understand the real estate industry.Originality/valueThis study allows foreigners who do not know Chinese to know more about factors that drove housing prices from the Chinese perspective. It also provides insights to overseas developers who wish to enter the property market in China. The results can be generalised to other non-English-speaking real estate research.

Effects of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection in mainland China: a meta-analysis.

The aim of this study was to explore the efficacy of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection in mainland China using meta-analysis. We searched China National Knowledge Network, Wanfang Medical Network, Chinese Science Citation Database, PubMed, and Embase Databases for publications of imipenem combined with glutamine in the treatment of severe acute pancreatitis abdominal infection. The search time limit was from the establishment of the database to April 10, 2021. Stata software version 12.0 was used for statistical analysis; the combined effect size odds ratio and standardized mean difference values were calculated for the count data and measurement data, respectively; and the heterogeneity test was performed in this study. A total of five randomized controlled trials were included. A total of 499 cases were included, with 251 in the observation group and 248 in the control group. Meta-analysis results showed that the efficacy of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection was significantly better than that of imipenem alone (odds ratio=0.78, 95%CI 0.71-0.86, p=0.040). Imipenem combined with glutamine can significantly improve the efficacy in the treatment of severe acute pancreatitis with abdominal cavity infection.

Assessment of research efficiency of critical care medicine in hospitals affiliated S university based on data envelopment method: taking the 13th Five-Year Plan period as an example

To investigate the static and dynamic trends of scientific research efficiency of the critical care medicine in hospitals affiliated S university during the 13th Five-Year Plan period. Based on the scientific research data of 16 hospitals affiliated to Beijing S University from 2014 to 2020, the scientific research investment funds and the number of physicians involved in scientific research were selected as input evaluation indexes, and the number of science citation index (SCI) papers, Chinese science citation database (CSCD) papers, and the number of masters and doctors trained were selected as output evaluation indexes, and the evaluation index system of scientific research efficiency of critical care medicine was constructed. SPSS version 23.0 software was used for descriptive data statistics, and data envelopment analysis (DEA)-BCC model and DEA-Malmquist index model of DEAP 2.1 software were used for static and dynamic evaluation of its scientific research efficiency from 2016 to 2020, respectively. (1) The scientific research technical efficiency (TE) of critical care medicine in 16 hospitals affiliated with S universities varied greatly from 2016 to 2020, but pure technical efficiency (PTE) and scale efficiency (SE) were at a good level, and 6-11 affiliated hospitals in critical care medicine kept DEA effective for 5 consecutive years. (2) Dynamic analysis of their total factor productivity (TFP) of scientific research from 2016 to 2020 showed a trend of rising and then falling and then rising again. The mean value was 0.985. The technical efficiency change (TEC) showed a decreasing and then increasing trend, and the technical progress change (TC) showed a slow increasing and then decreasing trend, with a mean value of 0.953. While the mean values of TEC, pure technical efficiency change (PTEC) and scale efficiency change (SEC) were above 1, which showed that the growth of total factor productivity index of research and innovation depended more on the technical efficiency index. The "gain effect" and "catch-up effect" of scientific research efficiency in the specialty of critical care medicine in hospitals affiliated S universities are obvious, but the "growth effect" is not obvious. "Although the research efficiency of the 13th Five-Year Plan period has been significantly improved, there is still much room for improvement in scientific and technological innovation and international academic influence.

The effect of mindfulness-based stress reduction therapy on maternal anxiety, depression, and sleep quality: A protocol for systematic review and meta-analysis.

Background:Depression and anxiety are common in the prenatal and postnatal periods, which significantly influence pregnant women and their unborn babies. Pharmacological interventions can negatively affect maternal and infant health outcomes, while psychotherapy can avoid adverse events of medication and improve maternal depression and anxiety. Whether mindfulness-based stress reduction (MBSR) can alleviate maternal anxiety and depression and improve sleep quality is still controversial. Therefore, we aim to conduct a meta-analysis by collecting randomized controlled trials (RCTs) reporting the effects of MBSR on maternal anxiety, depression, and sleep quality, thus providing evidence-based medical evidence for non-pharmacological interventions.Methods:RCTs reporting the effect of MBSR on maternal anxiety, depression, and sleep quality versus conventional obstetric care will be searched in online databases, including the Cochrane Central Register of Controlled Trials Repositories, PubMed, Embase, Web of Science, Chinese Science Citation Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journal Database, and Wan Fang Database. Literature selection, data extraction, risk of bias assessment, and meta-analyses will be independently completed by 2 researchers. Meta-analysis will be performed by using RevMan5.4.Results:The results of this meta-analysis will be submitted to a peer-reviewed journal for publication.Conclusion:This study will provide reliable evidence-based evidences for the effects of MBSR on improving maternal anxiety, depression, and sleep quality.

The effectiveness of mindfulness-based stress reduction intervention on alleviating anxiety and depression in postoperative patients with cervical cancer: A protocol for systematic review and meta-analysis.

Background:Surgical treatment for cervical cancer, as a stressor, largely leads to strong psychological reactions to stress like anxiety and depression. Whether mindfulness-based stress reduction (MBSR) can alleviate anxiety and depression in patients after cervical cancer surgery is controversial. Therefore, we aim to perform a meta-analysis involving randomized controlled trials analyzing the effect of MBSR on alleviating anxiety and depression in patients after cervical cancer surgery, thus providing evidence-based medical evidences for nonpharmacological interventions.Methods:Randomized controlled trials analyzing the effect of MBSR on alleviating anxiety and depression in patients after cervical cancer surgery will be searched in online databases, including Cochrane Central Register of Controlled Trials Repositories, PubMed, Embase, Web of Science, Chinese Science Citation Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journal Database, and Wan Fang Data. After screening eligible studies, we will perform a meta-analysis on the effect of MBSR on alleviating anxiety and depression in patients after cervical cancer surgery.Results:The results of this meta-analysis will be submitted to a peer-reviewed journal for publication.Conclusion:This study will provide reliable evidence-based evidences for the effects of MBSR on alleviating anxiety and depression in patients after cervical cancer surgery.Ethics and dissemination:Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms.OSF Registration number:DOI 10.17605/OSF.IO/EXUM3.

Research data policies of journals in the Chinese Science Citation Database based on the language, publisher, discipline, access model and metrics

AbstractThis article investigates the research data policies of China's scholarly journals to provide a regional perspective. In total, 1243 science, technology, and medicine (STM) journals in the Chinese Science Citation Database (CSCD) were examined in June and July of 2021. The findings show that the existence and attitudinal strength of the research data policies of China's scholarly journals are weak overall, but differences exist across journals with different languages, publishers, disciplines, access models and metrics. A large imbalance exists between English‐language journals and Chinese‐language journals in setting their research data policies. The existence and attitudinal strength of the research data policies of journals co‐published by Western publishers and Chinese publishers are much stronger than those of journals published solely by Chinese publishers. In terms of discipline, journals belonging to the life sciences have stronger attitudes towards research data sharing. Open access model journals and hybrid model journals are better than subscription model journals in opening and sharing research data. The higher the impact factor (IF) and CiteScore of a journal, the more likely the journal is to have data policies.

Effect of acupuncture treatment on cognitive impairment after traumatic brain injury in adults: A protocol for systematic review.

Background:Acupuncture has been widely used to treat cognitive impairment after traumatic brain injury (TBI). But its efficiency has not been scientifically and methodically evaluated. The objective of this study is to evaluate the efficiency and safety of the acupuncture treatment for cognitive impairment after TBI in adults.Methods:This protocol of systematic review will be conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols. We will conduct the literature searching in the following electronic databases: the Cochrane Library, MEDLINE, EMBASE, Web of Science, Springer, the Chinese Science Citation Database (CSCD), China National Knowledge Infrastructure (CNKI), the Chinese Biomedical Literature Database (CBM), Wanfang, and the Chinese Scientific Journal Database (VIP). The time limit for retrieving studies is from establishment to November 2021 for each database. All published randomized controlled trials related to this review will be included. Review Manager (V.5.3.5) will be implemented for the assessment of bias risk and data analyses. The selection of the studies, data abstraction, and validations will be performed independently by 2 researchers.Results:This review will assess the clinical efficacy and safety, as well as the acupoints characteristics of acupuncture on CI of TBI in adults.Conclusion:This review will summarize the current evidence of acupuncture on CI of TBI outcomes and provide guidance for clinicians and patients to select acupuncture for CI of TBI in adults.Trail registration number:This protocol of systematic review has been registered on INPLASY website (No. INPLASY2021110113).

Sodium tanshinone ⅡA sulfonate injection as adjunctive therapy for the treatment of heart failure: A systematic review and meta-analysis

BackgroundSodium tanshinone ⅡA sulfonate (STS) injection has been widely used to treat heart failure over the past years in China. However, to the best of our knowledge, neither systematic review nor meta-analysis on the efficacy of STS injection as adjunctive therapy for heart failure has been reported. ObjectiveThe aim of this study is to summarize relevant evidence from the published randomized controlled trials (RCTs) to evaluate the efficacy of STS injection as adjunctive therapy for heart failure. MethodsRCTs on STS injection as adjunctive therapy for the treatment of heart failure were screened from China National Knowledge Infrastructure (CNKI), Wanfang Database, Sino-Med, PubMed, Google Scholar, Medline, China Science and Technology Journal Database (VIP), Chinese Biomedical Literature Database, Cochrane Library, Embase and Chinese Science Citation Database until July 2021. Two authors independently performed the literature searching, data extraction, and quality evaluation. The meta-analysis was carried out by RevMan 5.3. Based on the methodological quality, years of publication, and sample size of the included RCTs, sensitivity analysis and subgroup analysis were investigated. ResultsFourteen RCTs with a total of 1368 patients were identified in this study. Results from this meta-analysis showed that STS injection as adjunctive therapy was superior to western medicine alone for the treatment of heart failure in improving the total effective rate (RR = 1.23; 95% CI, 1.17 to 1.29; p < 0.00001) and the left ventricular ejection fraction (LVEF; MD = 6.34; 95% CI 5.25 to 7.43; p < 0.00001), meanwhile reducing the left ventricular end-diastolic diameter (LVEDD; MD = -4.79; 95% CI, -6.44 to -3.15; p < 0.00001), left ventricular end-systolic dimension (LVESD; MD = -3.98; 95% CI, -5.79 to -2.17; p < 0.0001) and brain natriuretic peptide (BNP; MD = -118.75; 95% CI, -175.36 to -62.15; p < 0.0001). ConclusionsThis study indicated that STS injection as adjunctive therapy seemed to be more effective than western medicine alone in treating heart failure. However, due to the poor methodological quality of the included RCTs, further well-designed RCTs are required to confirm the efficacy of STS injection.
