ObjectiveTo understand the current state of medical graduate student labor education in the new era and its effectiveness, to explore the mechanism by which labor education affects labor practices, and to identify intervention points for improving labor education. MethodsA questionnaire survey was conducted from July 3 to 13, 2022, on the labor education of 216 medical graduate students from 10 double-first-class universities. The relationship between labor education, labor awareness, labor ability, and labor practices was analyzed. ResultsDescriptive analysis results showed that medical graduate students received little labor education. The structural equation model results showed that labor education positively impacted labor awareness (γ=0.712) and labor ability (γ=0.755), and labor awareness and labor ability positively impacted labor practices (γ=0.400, γ=0.635), indicating that labor education has a positive impact on labor practices. ConclusionTo improve the weak state of medical graduate student labor education, it is necessary to increase related training and courses, enrich the types and content of labor education, strengthen the assessment mechanism of labor education, and strengthen the responsibilities of instructors.
ObjectiveTo summarize the new biomarkers of deep venous thrombosis (DVT) and their research progress, so as to provide new ideas for the prevention, diagnosis and treatment of DVT. MethodThe literature about biomarkers of DVT in recent 5 years was reviewed and summarized. ResultsAccording to the results of literature review, a variety of common DVT biomarkers such as serum microrna, fibrin monomer, neutrophil capture net, and E-selectin were sorted out, but most of them had not been used in clinical DVT management. At present, the clinical diagnosis of DVT required the combination of positive D-dimer test and positive imaging examination, and there was no single biomarker for the diagnosis of DVT. ConclusionsBiomarkers are valuable in the diagnosis and treatment of DVT, but their sensitivity and specificity need to be optimized. Therefore, finding biomarkers with more diagnostic value is one of the future directions. At the same time, we also can consider fully combined with a variety of existing biomarkers, to improve the efficiency to the diagnosis of DVT.
【摘要】 目的 调查胃癌患者的营养风险及营养支持应用现状。 方法 2009年9月-2010年1月，对某三甲医院普外科收治的120例胃癌住院患者营养情况进行营养风险筛查2002（nutritional risk screening 2002，NRS 2002）评估，并就营养支持应用方式进行分析。 结果 所有患者中营养不足和营养风险的发生率分别为11.7%和27.5%；在33例有营养风险患者中，有26例（78.8％）接受了营养支持；在无营养风险的87例患者中，有30例（34.5％）接受了营养支持。 结论 对有营养风险的患者进行必要的营养支持，对于减少患者住院期间感染性并发症或其他不良临床结局的发生有积极作用。NRS 2002的方法简便，适用于胃癌患者的营养风险筛查，但医护人员需要进一步加强对肠外、肠内营养指南的认识。【Abstract】 Objective To investigate the clinical situation of nutritional risk screening for hospitalized patients with gastric cancer. Methods From September 2009 to January 2010, we applied nutrition risk screening 2002 (NRS 2002) to investigate the nutritional status of 120 hospitalized gastric cancer patients in the surgery department of a tertiary hospital, and analyzed the way of nutritional support for these patients. Results Among all the patients, the incidences of undernutrtion and nutritional risk were respectively 11.7% and 27.5%. Twenty-six out of the 33 nutritional risk patients received nutrition support, and 30 out of the 87 patients without nutritional risk received nutrition support. Conclusions Nutritional support for patients with nutritional risk is important in decreasing the occurrence of in-hospital infectious complications and other bad clinical outcomes. NRS 2002 is a simple and easy tool for predicting the nutrition risk in hospitalized gastric cancer patients, but the guideline of enteral nutrition and parenteral nutrition must be reinforced among doctors and nurses.
During the coronavirus disease 2019 (COVID-19) epidemics, universities take responsibility for the health of their students and epidemic control. Our urgent recommendation focuses on four key questions of emergency management in universities following rigorous evidence-based approaches and provides timely suggestions to university managers, academic faculties and student affairs managers. We recommend universities during the COVID-19 epidemics should: 1) suspend offline lectures; 2) provide proper health education on the disease; 3) encourage face masks, however oppose using N95 masks on the campus; 4) encourage hand hygiene and provide sanitizing products on the campus.
