Primary liver cancer is the sixth most common malignancy and the third leading cause of cancer-related death worldwide, and hepatocellular carcinoma (HCC) constitutes the majority of primary liver cancer cases. The Liver Imaging Reporting and Data System (LI-RADS) was introduced to standardize the lexicon, acquisition, interpretation, reporting, and data collection of imaging results in patients at increased risk for HCC. LI-RADS allows effective categorization of focal liver lesions, and has been applied in the full clinical spectrum of HCC from diagnosis, biological behavior characterization, prognosis prediction, to treatment response assessment. This review aimed to summarize the recent applications of CT/MRI LI-RADS in the diagnosis, biological behavior characterization and prognosis prediction of HCC, discuss current challenges and shed light on potential future directions.
Purpose To study the possibility of prevention of proliferative vitreoretinopathy(PVR) by transduction of exogenous gene in vivo. Methods PVR model of rabbits was induced by intravitreal injection of fibroblasts.beta;-galactosidase (lacZ) gene as a reporter gene was transfered into the vitreous of PVR model eyes mediated by retroviral vector, and the expression of the gene in eye tissues was determined . Gene transfection was done on the 6th day after fibroblasts injection,and the dosage of intravitreal injection of reporter gene was 0.1ml PLXSN/lacZ serum-free supernatant (1.1times;106 cfu/ml). Results lacZ gene expression was seen in proliferative membranes after gene transfection, and the expression was located maily at the surface of PVR membrane.The reporter gene expression lasted at least more than 30 days.No expression was found in retinal tissues. Conclusions Retrovirus mediated gene can be directionally transducted in PVR membrane,and might possess the feasibility of gene therapy for PVR. (Chin J Ocul Fundus Dis, 2001,17:224-226)
The selection of outcome measurement instruments (OMI) is a prerequisite for accurately collecting health outcome data. Conducting a systematic review of OMI can provide an important reference for researchers and practitioners to select the most appropriate OMI. In order to improve the reporting quality of the systematic review of OMI, foreign researchers published the PRISMA-COSMIN reporting guideline in the J Clin Epidemiol in June 2024. This article introduces the research team, development process, and items of the reporting guideline, and analyzes the items with examples. We hope our attempt could help domestic researchers improve the overall quality of OMI systematic reviews.
The surgical case report(SCARE)statement is the report checklist made by European researchers in 2016, which is specialized for surgical case report. As a reference for enhancing the research quality and transparency, the SCARE statement provides a fundamental framework for surgical case reports. The last SCARE statement was revised in 2020, and this paper interprets it to provide a practical tool for domestic researchers in surgical case report.
According to the evidence pyramid model, systematic review (SR)/meta-analysis (MA) is one of the essential sources with a high level of clinical evidence. A high-quality SR/MA can effectively guide clinical decision-making and practice. The preferred reporting items for systematic reviews and meta-analyses extension for Chinese herbal medicines (PRISMA-CHM) were officially published in 2020. In this study, based on research cases, the features of PRISMA-CHM were interpreted in detail, so as to help domestic users accurately grasp the details of the reports, in order to improve the quality of the reports of SR/MA of traditional Chinese medicine.
ObjectiveTo enhance the management of occupational exposure, improve post-exposure reporting, promote post-exposure follow-up, reduce blood-borne infections caused by exposure, and ensure occupational safety among medical staff by using comprehensive measures based on nosocomial infection management system.MethodsAll the reported cases of occupational exposure were retrospectively collected from August 2012 to July 2018. The cases were divided into the control group (from August 2012 to July 2015) in which the data were reported in paper, and the observation group (from August 2015 to July 2018) in which the data were reported by nosocomial infection management system. The report and follow up results of occupational exposure in the two groups were compared and analyzed.ResultsAfter three years application of nosocomial infection management system, the occupational exposure report increased 95.8% (increased from 16.7 cases per year to 32.7 cases per year); the follow-up ratio of occupational exposure after one month,3 months and 6 months increased from 65.0% to 93.3% (χ2=15.184, P<0.001), 45.0% to 73.3% (χ2=9.033, P=0.003), and 25.0% to 53.3% (χ2=8.522, P=0.004), respectively.ConclusionApplication of nosocomial infection management system can increase the report of occupational exposure and the follow-up ratio of occupational exposure significantly.
This study aimed to provide suggestions for future researchers to select and optimize sham acupuncture reporting guidelines in acupuncture clinical trials. Through qualitative analysis, we compared the basic information and concrete contents between Acupuncture Controls gUideline for Reporting humAn Trials and Experiments (ACURATE) and SHam Acupuncture REporting guidelines in clinical trials (SHARE) developed by researchers from China and Korea. In addition, the similarities and differences of the two guidelines were illustrated through a specific case. We found that the two guidelines had their own characteristics and emphasis in content, but both emphasized the reports of detailed information and background factors of sham acupuncture compared with the previous STRICTA and TIDieR-Placebo checklist. In terms of item division, we found that the ACURATE split the same topic into several items to emphasize the importance of each item content. SHARE emphasized the comprehensive reports of sham acupuncture by combining several items into a single item. In terms of item content, ACURATE also focused on combination therapy, the information regarding sham acupuncture provided to participants, and any differences in treatment settings between versus/sham acupuncture, which had some referential meaning for setting sham acupuncture control. SHARE also focused on sham acupuncture detailed information, practitioner, and modifications, etc. Case analysis showed that there were some "not reported" or "partially reported" items in both guidelines. Therefore, it is suggested that researchers can use the above two guidelines to complement and learn from each other to report sham acupuncture. In addition, it is necessary for researchers to verify the operability and practicability of the above two guidelines, and provide suggestions for optimizing and updating them in the future.
ObjectiveTo get known of the application of Preferred Items of Systematic Review and Meta Analysis (PRISMA). MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 10, 2013), CBM, WanFang Data and CNKI, to collect relevant literature about the application of PRISMA during 2009-2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and then bibliometric analysis was performed using Excel software. ResultsWe finally included 175 papers, including 26 conference abstracts and 149 full texts. The results of bibliometric analysis of full texts showed that, they were published in 118 journals, and PRISMA official website announced that 176 journals endorsed the application of PRISMA. According to study type, there were 111 systematic reviews and meta-analyses (SRs/MAs) for development and reporting, 20 overviews of SRs for reporting quality assessments, 7 versions of PRISMA interpretation, and 11 articles of other kinds. In 131 SRs/MAs as well as overviews, the studies about western medicine accounted for 77.8%, followed by public health (8.4%), and traditional Chinese medicine (4.6%). ConclusionThe application of PRISMA statement is still at the first phase and mainly confined to the field of western medicine, which needs more attention and understanding. Thus, it's necessary to interpret and disseminate the PRISMA statement.
