LMX1B-associated disease presented with prominent asymptomatic proteinuria / 中华实用儿科临床杂志

Objective:To analyze clinical data of 3 children with LMX1B-associated disease characterized by asymptomatic glomerular proteinuria, thus improving the recognition of asymptomatic proteinuria with genetic causes. Methods:Three patients with LMX1B-associated disease presented with prominent asymptomatic proteinuria diagnosed by the next-generation sequencing in Department of Pediatrics, Peking University First Hospital from April 2014 to October 2017 were included in this study.Clinical data, including renal and extrarenal manifestations, renal biopsy, and family history, were collected and retrospectively analyzed. Results:All 3 children were girls, the age of onset were 2 years, 1 year, and 4 years, respectively, and the diagnosis age were 11 years, 5 years and 6 years, respectively.All of them had glomerular proteinuria, and nephrotic-level proteinuria occurred in one patient.Microscopic hematuria was found in 2 patients.All of them had normal renal function.Only one patient underwent renal biopsy.Electron microscopy of the first time of biopsy revealed segmental thinning of the glomerular basement membrane.Re-biopsy 4 years later showed irregular thickening of the glomerular basement membrane, moth-eaten appearance and collagen fibrillar material deposition.No abnormalities of nails, limbs and joints were observed by physical examination.Two patients had a family history of renal disease.Conclusions:Genetic factors should be considered in children with obscure onset asymptomatic proteinuria without definite clinical causes.Genetic testing can help diagnose and guide treatment as early as possible.

Analysis of the frontier and hotspot of screening technology for early lung cancer based on bibliometrics / 中国胸心血管外科临床杂志

@#Objective    To reveal and demonstrate the hotspots and further research directions in screening technology for early lung cancer, and provide references for the future studies. Methods    Researches related to lung cancer screening from 2011 to 2021 in the Web of Science database were included. Biblioshiny, a bibliometrics program based on R language, was used to perform content analysis and visualization of the included literature information. Results    Researches related to lung cancer screening were increasing year by year. Six major cooperation groups were formed between countries. The current research hotspots in the field of early lung cancer screening technology mainly focused on the multi-directional fusion of radiographic imaging, liquid biopsy and artificial intelligence. Conclusion    Low-dose spiral CT screening is still the most important and mainstream method for the screening of early lung cancer at present. The combination and integration of artificial intelligence with various screening methods and the innovation of novel testing and diagnostic equipment are the current research hotspots and the future research trend in this field.

An analysis of global research on SARS-CoV-2 / 生物医学工程学杂志

The SARS-CoV-2 has been spread to 26 countries around the world since its outbreak. By February 16, 2020, more than 68 000 people had been diagnosed with COVID-19. Researchers from all over the world have carried out timely studies on this public health emergency and produced a number of scientific publications. This review aims to re-analyze and summarize the current research findings in a timely manner to guide scholars in relevant fields to further SARS-CoV-2 research and assist healthcare professionals in their work and decision-making. The SARS-CoV-2 related terms were selected in both English and Chinese and were searched in several major databases, including Pubmed, Web of Science, CNKI, Wanfang, and VIP databases. The reference list of each search result was screened for relevance, which was further supplemented to the search results. The included studies were categorized by topics with key characteristics extracted, re-analyzed, and summarized. A total of 301 articles were finally included with 136 in Chinese and 165 in English. The number of publications has rapidly increased since mid-January, 2020, and a peak day was 6th February on which 50 articles were published. The top three countries publishing articles were China, the United States and the United Kingdom. The and its specialty journals have published the most articles, with contribution also from journals such as ( ), ( ), and . All articles were categorized into epidemiology, clinical diagnosis and treatment, basic research, pregnant women and children, mental health, epidemic prevention & control, and others. The literatures related to SARS-CoV-2 are emerging rapidly. It is necessary to sort out and summarize the research topic in time, which has a good reference value for staff in different positions. At the same time, it is necessary to strengthen the judgment of the quality of literatures.

Global research hotspots on oncology-bibliometric analysis based on the ESI hot papers / 生物医学工程学杂志

With the increasing global burden of various cancer, an abundance of papers emerged every year in the research hotspots of oncology, covering a wide range of research types and topics. In order to facilitate interested readers to quickly grasp the frontier and hotspots of cancer research, it would be helpful to sort out and summarize the research topic in a timely manner. According to the classification of disciplines, we screened the Essential Science Indicators (ESI) hot papers released in 2019 for the ones in the oncology field, utilized methods such as bibliometrics, statistical description, hierarchical induction, analysis and interpretation to further reveal the context and characteristics of research in the field of oncology, summarized the latest progresses and future directions in the field, and provided information and hints for the trajectory of future research. A total of 549 papers were included, which were mainly from the field of clinical medicine; the country with the most publications was the United States, while China ranked the fourth in terms of contribution; the research institution with the highest number of published papers was University of Texas system;

Global research hot points on cardiovascular disease--bibliometric analysis based on the ESI hot papers / 生物医学工程学杂志

With the heavier burden of cardiovascular disease, an abundance of papers emerge every year in the research hotspots, which cover a wide range of types and content. In order to let readers interested in the cardiovascular field quickly understand the research hotspots and research frontier, it is necessary to sort out and summarize the research topic in time. According to the discipline classification, we screened papers in cardiovascular field from the Essential Science Indicators (ESI) hot papers published in 2019. Methods such as bibliometrics, statistical description, hierarchical induction, analysis and interpretation were used a step further to reveal the context and characteristics of research in the field of cardiovascular diseases, summarize the latest progress and development direction in this field, and provide information and hints for the expansion of future research directions. A total of 297 papers were finally included, which were mainly in the field of clinical medicine; The country with the most publications was the United States, while China ranked the fifth in terms of contribution; the research institution with the highest number of published papers was Harvard University;
