ObjectiveTo interpret the intervention description and reporting standards (TIDieR), and further present the domestic and international application status of TIDieR based on knowledge graphs. And to provide references and inspirations for standardized reporting of intervention studies. MethodsTIDieR-related literature published in Chinese and English databases such as CNKI, WanFang Data, PubMed, and Web of Science was searched from 2014 to 2024, and visual analysis was conducted using CiteSpace6.3.R1 bibliometric software. ResultsTIDieR consisted of 12 entries, including abbreviated intervention name, implementation rationale, implementation materials, implementation process, implementer, implementation method, implementation site, implementation time and intensity, personalized plan, plan changes, expected effects, and actual effects. The bibliometric analysis included 94 English-language papers and 5 Chinese-language papers. The application of TIDieR was relatively widespread overseas, mainly involving health care, rehabilitation, and digital health fields. ConclusionTIDieR can ensure the standardization and reproducibility of intervention research reports. However, domestic scholars still apply TIDieR less frequently. It is necessary to gradually promote and strengthen the application of TIDieR in future intervention studies, thereby improving the transparency and quality of intervention research reports.
ObjectiveTo analyze the application status of Kanban management in medical service management at home and abroad and to provide a reference for lean medical management practice in China.MethodsUsing the bibliometric method, in China National Knowledge Infrastructure, Wanfang Database, CQVIP Journal Database, Springer Link, Embase and PubMed, we used “Kanban” and “Kanban management” as Chinese search terms, “Kanban system” and “two-bin system” as English search terms to search for literature published from 2009 to 2019. The number of articles published, institutions, authors, citation frequencies, key words, Kanban usage, and improved areas where Kanban was applied in were statistically described and analyzed.ResultsA total of 219 articles were retrieved. Of the 14 articles included in the study, 12 articles were published from 2015 to 2019, 8 articles were published by hospitals, and 9 articles were cited more than or equal to 3 times. The key words were basically the combinations of Kanban and related topics in the field of medical service management, such as quality control and improvement, ward service, high-quality care and process evaluation; 11 articles used Kanban alone. Kanban was used in medicine supply chain management, ward bed management, and material inventory management abroad; and was used in medicine management, emergency room patient management, medical staff performance management, operating room equipment management, and high-quality medical service management in China.ConclusionsKanban as a lean management method was introduced into the domestic medical field late, and the current research development is not balanced. Asa visual management tool, Kanban needs to be extended in the medical field. As a lean improvement tool, Kanban has positive significance in improving medical quality and patient satisfaction. It is suggested that researchers should not be limited to the existing applied research, and can study the application of Kanban in different medical service fields in combination with different lean management tools according to the actual situation of the hospital.
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.

Methods Using word frequency analysis and cluster analysis as analysis methods, CiteSpace visualization software and Excel statistical software as tools, the domestic and foreign SBME literature retrieved from PubMed and CNKI databases were visualized and statistically analyzed respectively. Results A total of 2 491 domestic and foreign literature on SBME in thoracic surgery were included. The annual number of foreign publications showed an increasing trend. The top three countries in terms of number of publications were the USA (n=581), Canada (n=105) and Germany (n=57); "cardiac surgery", "medical knowledge medical knowledge" and "medical education" are the hotspots of research in the direction of thoracic surgery simulation, while "lung cancer", "surgical training" and "3D printing" were still in the process of explosion. The core research themes were endoscope simulation trainer, scenario-based simulation teaching methods, standardized patients and virtual reality models. Conclusion Domestic SBME in thoracic surgery should learn from foreign development experience, keep up with the frontier and integrate cutting-edge technology, innovate the curriculum and offer non-technical skills teaching, and improve the system and focus on software construction.
Objective To investigate how many hospitals can perform vitrectomy and its relationship to economic development in China.Methods Bibliometric data of retina-vitreous literatures were searched from the China National Knowledge Infrastructure (CNKI) academic databases. We used pars plana vitrectomy (PPV) as a keyword and defined address as mainland China, limited years to 1993 -2009. From those data we analyzed which hospital performed PPV. We also communicated with some hospitals by phone, email to confirm if they were performing PPV. Gross domestic product (GDP), population data and economic development ranking were extracted from the China Statistical Yearbook 2009 (National Bureau of Statistics of China). PPV carry-out rate, PPV-hospital shares and their relationships with the GDP in each regional municipality were analyzed.Results All together this study retrieved 4632 articles meet our requirements. There were 340 hospitals carrying out PPV in mainland China, located in 22 provinces, five autonomous regions and four metropolitan municipalities. The top five provinces with higher PPV carryout rate were Shandong (93,75%), Zhejiang (90,00%), Hebei province (90.00%), Jiangsu (83.33%) and Guangdong (75.00%). There was significant difference in per capita share of PPVhospitals between different cities (chi;2=181,153，P=0,000) and in the PPV carry-out rate between different cities (chi;2=749.217，P=0.000). There were 210 private eye hospitals in China,62 hospitals (18.23%) of them could perform PPV included 39 hospitals located in regionallevel cities. The coefficient correlation between PPV and GDP of different provinces was 0.842 (P=0.000). Conclusions Vitrectomy is widely performed in mainland China, but geographical distribution of PPV-performing hospitals is uneven. PPV performance is closely related with regional economic development,and private hospitals play certain roles in promoting the application of vitrectomy.

Microfluidics is the science and technology to manipulate small amounts of fluids in micro/nano-scale space. Multiple modules could be integrated into microfluidic device, and due to its advantages of microminiaturization and controllability, microfluidics has drawn extensive attention since its birth. In this paper, the literature data related to microfluidics research from January 1, 2006 to December 31, 2021 were obtained from Web of Science Core Collection database. CiteSpace 5.8.R3 software was used for bibliometrics analysis, so as to explore the research progress and development trends of microfluidics research at home and abroad. Based on the analysis of 50 129 articles, it could be seen that microfluidics was a hot topic of global concern, and the United States had a certain degree of authority in this field. Massachusetts Institute of Technology and Harvard University not only had a high number of publications, but also had strong influence and extensive cooperation network. Combined with ultrasonic, surface modification and sensor technology, researchers constructed paper-based microfluidic, droplet microfluidic and digital microfluidic platforms, which were applied in the field of immediate diagnosis, nucleic acid and circulating tumor cell analysis of in vitro diagnosis and organ-on-a-chip. China was one of the countries with a high level of research in the field of microfluidics, while the industrialization of high-end products needed to be improved. As people’s demand for disease risk prediction and health management increased, promoting microfluidic technological innovation and achievement transformation is of great significance to safeguard people’s life and health.
ObjectiveTo systematically review the disease burden and epidemiological characteristics of diabetes mellitus in Chinese population, and to provide references for health resources allocation and health policy making. MethodsDatabases such as PubMed, EMbase, CNKI, VIP and WanFang Data were searched for studies investigating disease burden of diabetes mellitus in Chinese population up to January 1st, 2014. According to the inclusion and exclusion criteria, two researchers screened literature, exacted data, and assessed methodological quality of included studies. Statistical analysis was performed with the data of diabetes associated population, mortality and disease burden were analyzed. ResultsA total of 39 studies were included, one of which was not included for further qualitative analysis due to low quality. The results of qualitative analysis involving 38 studies showed that, since 1980, the prevalence of diabetes increased rapidly in China, especially in the younger age group. The disease burden of woman was higher than that of man; it was slightly higher in the city than in the countryside; but the gap between urban and rural areas was gradually narrowed. Disease burdens in Eastern, Central and Western regions orderly decreased, all of which were all at high levels. ConclusionThe disease burden of diabetes mellitus in China is seriously high and the prevention and control work is very hard. It is necessary to rationally and effectively allocate health resources based on different health demands in different regions among urban-rural and age groups; to reduce the burden in the elderly; and to pay more attention to the young age population at the same time. Besides, the emphasis of prevention should be placed on suppressing the increase of prevalence of diabetes mellitus and reducing disease burden due to its complications.
