Establishment of the data capture and management platform for case-control study on precocious puberty based on REDCap system / 西安交通大学学报(医学版)

【Objective】 To conduct a case-control study on precocious puberty as an example to introduce the establishment and design of the electronic Data capture and management platform using Research Electronic data Capture (REDCap) system and support the development of clinical research. 【Methods】 Based on the clinical REDCap system, the case-control research project of precocious puberty was created, the case report forms were designed, the user rights were set, and the data quality control rules were formulated. 【Results】 We established the electronic data capture and management platform for our research, which had 15 case report forms, to collect the data of the participants, including sociodemographic information, time for rest and activities, diet, exposure to environmental internal-secretion interfering-substances, physical examination and biochemical indicators. We conducted project management by setting up features such as user permissions and workgroups, and added data quality verification rules to control data quality. The data could be exported in various file formats for analysis and sharing. 【Conclusion】 The application of REDCap to establish the data capture and management platform of precocious puberty case-control study has promoted the efficient implementation of clinical research, which can be further popularized and applied to clinical researches in other fields.

Research progress on mechanism of intestinal mucosal mechanical barrier injury associated with severe acute pancreatitis / 中华肝胆外科杂志

Severe acute pancreatitis (SAP) is closely related to intestinal mucosal barrier dysfunction, in which intestinal epithelial mechanical barrier injury is the structural basis of SAP-related intestinal mucosal dysfunction. Among the molecular mechanisms of injury factors, inflammatory mediators and cytokines, produced by SAP waterfall inflammation, are the main factors of intestinal mucosal barrier injury. This article briefly describes the effects of SAP on intestinal mechanical barrier injury and its molecular mechanism in order to provide ideas for the treatment of SAP.

Current status of the research on laparoscopic cholecystectomy / 临床肝胆病杂志
