BOPPPS教学模式在医科院校医用化学教学中的应用与思考

医用化学是医学院校一门重要的基础必修课程,内容多为知识理解型,这导致了学生兴趣薄弱,学习效果欠佳。因此,需要通过改革传统"灌输式"课堂授课方式,让学生真正参与到教学活动中。BOPPPS教学模式分为导言、学习目标、前测、参与式学习、后测和总结六个环节。突出"以学生为中心"的教学理念,遵循教学活动的客观规律。在医用化学课程的教学过程中引入BOPPPS教学,能够有效提高学生的课堂参与度,增强学生的学习动力,培养学生独立思考、自主学习的能力。

目的 研制用于核事故放射性污染伤员空运后送防护服。方法 根据放射性污染伤员的后送救护和污染防护要求，选用防污材料，设计结构布局，在演练行动中论证该防护服的合理性和实用并加以改进。结果 该型防护服材料具有较好的防渗透、耐腐蚀等理化特性，整体采用连体式结构，对伤员体表覆盖率达到97%，设计6个医学操作窗口和体侧游离拉链，达到了有效防止伤员体表放射性污染扩散和方便医疗救护的效果。结论 完成了放射性污染伤员空运后送防护服的研制，可满足核事故救援行动中伤员转运需要。     

Effect of a Device-Free Compressed Shell Fixation Method on Hepatic Respiratory Movement: Analysis for Respiratory Amplitude of the Liver and Internal Motions of a Fiducial Marker

Purpose

Suppression of respiratory movement of the liver would be desirable for high-precision radiation therapy for liver tumors. We aimed to investigate the effect of our original device-free compressed shell fixation method and breathing instruction on suppression of respiratory movement. The characteristics of liver motion based on the movement of a fiducial marker were also analyzed.

从武汉抗疫看中医药文化认同与新的医学模式

从武汉抗疫中医药的投入使用情况,反思现代临床和国人所呈现出的中医药文化认同和就医习惯,探索其历史文化根源及社会因素与医学发展的内在关联。回顾历史,中医屡次临危受命,不负重托,如今大疫当前,中医药再次发挥了重要作用。故新时代探讨如何遵循中医药发展规律,传承精华、守正创新,坚持中医药原创优势,形成中医药学科优势整体化呈现的新模式医学,对提升全社会的中医药认知度具有重要意义。     

医用粘胶相关性皮肤损伤的文献计量学分析

目的: 应用文献计量学方法,分析国内外医用粘胶相关性皮肤损伤（Medical adhesive-related skin injuries,MARSI）文献的研究主题和热点。方法: 检索Cochrane Library、PubMed、EMbase、Web of science、sinoMed、CNKI、Wanfang、VIP等数据库MARSI相关文献,检索时限为建库至2019年5月。采用SPSS 22.0 软件进行文献计量分析,利用gCLUTO统计对国内外高频主题词进行聚类分析。结果: 共纳入论文103篇,其中外文文献占总文献量的27.18%,中文文献占总文献量的72.82%。聚类分析将国内外高频主题词聚为4大类,依次为皮肤损伤及损伤类型、相关危险因素、风险评估及风险管理、护理干预措施。结论: MARSI仍是国内外研究的热点,其发病机制研究仍处于探索阶段,目前尚缺乏有效的预防策略,研究领域较局限。在今后的研究中,应加强MARSI预防的研究、注重多学科合作。     

Incidence of community-acquired pneumonia in urban China: A national population-based study

BackgroundCommunity-acquired pneumonia (CAP) is one of the major global health problems worldwide. However, the epidemiological information of CAP is limited in China. This study aimed to estimate the incidence rate of CAP and describe the epidemiologic characteristics among the Chinese population.MethodsWe conducted a retrospective analysis of CAP incidence using the Chinese Urban Basic Medical Insurance database of 23 provinces in 2016, which covered 427.52 million urban beneficiaries of all age groups in Mainland China. CAP episodes were identified using a diagnosis-term-derived algorithm, and multiple CAP records of one single person within 90 continuous days were considered as one single episode. The incidence rates were calculated and described by sex, age, region, and season.ResultsA total of 1.42 million patients were identified as having one or more CAP episodes, and finally a sum of 1.48 million CAP episodes were counted. The overall incidence of CAP was 7.13 (95% CI: 6.11–8.15) per 1000 person-years, in males 7.32 (95% CI: 6.28–8.35) and females 6.93 (95% CI: 5.92–7.94) per 1000 person-years, respectively. The incidence varied by age with a U-shaped curve peaking in children aged < 5 years old [65.80 (95% CI: 62.52–69.08)] and elderly population aged ≥ 80 years old [14.98 (95% CI: 13.63–16.34)]. The incidence varied markedly by regions. Furthermore, the rate showed a clear seasonal trend, which peaked in spring, decreased in summer and autumn, and re-ascended in winter.ConclusionThis study reveals a relatively high level of CAP incidence in China. These findings provide baseline data for establishing effective prevention strategies, targeted at susceptible populations, regions, and seasons in China.
