基于虚拟教研室的公共卫生安全素养培育课程构建及实践

目的:探讨基于虚拟教研室的公共卫生安全素养培育课程构建及实践。方法:选取某医学院校专科护理专业学生(护生)为研究对象,将护理1班45人作为试验组,将护理2班43人作为对照组,对照组对公共卫生安全知识实施线上与线下的常规教学,试验组实施基于虚拟教研室的公共卫生安全素养培育课程。比较两组护生内容掌握情况及学习满意度。结果:试验组护生的学习成绩明显高于对照组(P<0.01),试验组护生对教学的满意度为95.6%(43/45),明显高于对照组(P<0.05)。结论:基于虚拟教研室的公共卫生安全素养培育课程构建既可以广泛促进不同专业教师进行教学研究交流,全面提高教师教书育人能力,又可以使护生在学习过程中接触不同专业、不同领域的知识与技能,注重护生主体作用,提高学习效果和学习满意度。

中文科技期刊术语规范化现状:调查与分析

【目的】 对术语使用情况进行调研,找出术语使用不规范的问题,为提升我国科技期刊术语规范化水平、推进科技期刊高质量发展提供依据。【方法】 采用回顾性调查方法,选择18种科技期刊2020年全年刊出的所有文章,调查其中术语使用差错情况。【结果】 术语相关差错主要涉及术语使用规范问题、术语编校规范问题及专有名词术语规范问题,具体差错类型比较多样化,不利于期刊质量及影响力的提升,应引起论文作者及期刊工作者的高度重视。术语相关差错中,术语使用规范问题最为突出;术语使用规范问题的各种类型中,术语形音义相近而误的现象最为突出。【结论】 我国科技期刊术语规范化水平有待提升,需要引起重视。     

Motivational interviewing for maternal Immunizations: Intervention development

Background and ObjectiveVaccine uptake during pregnancy remains low. Our objectives were to describe 1) development and adaptation of a clinician communication training intervention for maternal immunizations and 2) obstetrics and gynecology (ob-gyn) clinician and staff perspectives on the intervention and fit for the prenatal care context.MethodsDesign of the Motivational Interviewing for Maternal Immunizations (MI4MI) intervention was based on similar communication training interventions for pediatric settings and included presumptive initiation of vaccine recommendations (“You’re due for two vaccines today”) combined with motivational interviewing (MI) for hesitant patients. Interviews and focus group discussions were conducted with ob-gyn clinicians and staff in five Colorado clinics including settings with obstetric physicians, certified nurse midwives (CNMs), and clinician-trainees. Participants were asked about adapting training to the ob-gyn setting and their implementation experiences. Feedback was incorporated through iterative changes to training components.ResultsInterview and focus group discussion results from participants before (n = 3), during (n = 11) and after (n = 25) implementation guided intervention development and adaptation. Three virtual, asynchronous training components were created: a video and two interactive modules. This virtual format was favored due to challenges attending group meetings; however, participants noted opportunities to practice skills through role-play were lacking. Training modules were adapted to include common challenging vaccine conversations and live-action videos. Participants liked interactive training components and use of adult learning strategies. Some participants initially resisted the presumptive approach but later found it useful after applying it in their practices. Overall, participants reported that MI4MI training fit well with the prenatal context and recommended more inclusion of non-clinician staff.ConclusionsMI4MI training was viewed as relevant and useful for ob-gyn clinicians and staff. Suggestions included making training more interactive, and including more complex scenarios and non-clinician staff.     

基于HPLC指纹图谱、多指标成分含量测定结合化学计量学的怀牛膝质量评价＊

目的 本实验采用HPLC方法建立来自3个产地15批怀牛膝药材的指纹图谱，并对β-蜕皮甾酮，25R-牛膝甾酮，25S-牛膝甾酮进行含量测定，同时通过化学计量学的方法对15批怀牛膝进行质量评价。方法 选用Waters SunFire C₁₈（150 mm×4.6 mm，5 μm）色谱柱，检测波长280 nm，以乙腈-0.1%甲酸水梯度洗脱，流速为1.0 mL·min^-1，柱温25℃，进样量10 μL。以β-蜕皮甾酮峰为参照峰，运用软件《中药色谱指纹图谱相似度评价系统（2012版）》对15批怀牛膝药材进行相似度分析，使用Metabo Analyst 5.0网站进行聚类热图分析，使用SIMCA 14.1软件进行PCA和PLS-DA分析。结果 标定了31个共有指纹峰，指认了3个已知成分，并对其进行含量测定，化学计量学分析结果将15批怀牛膝药材样品分为3类，并且筛选了不同产地间潜在的差异性成分。结论 该方法具有良好的精密度、重复性以及稳定性，可为怀牛膝的质量评价与控制提供科学依据及参考。     

药物饲料添加剂吉他霉素耐药性风险评估

目的 为给兽药减量政策的制定、动物源性食品安全的维护提供理论依据。方法 利用每日允许摄入量（ADI）、估算每日摄入量（EDI）及慢性风险熵（CRQ），对中国居民通过摄入肉蛋乳等动物性食品暴露于吉他霉素的耐药性风险进行点评估。结果 随着年龄增长，中国居民的吉他霉素膳食暴露量逐渐降低。2～7岁人群吉他霉素的膳食暴露量最高，男女分别为2.17和2.29 μg/ ( kg·bw·d)；＞65岁人群膳食暴露量最低，男女分别为0.45和0.46 μg/ ( kg·bw·d)。2～7岁人群通过摄入乳制品的吉他霉素的膳食暴露量最大，男女分别为1.15和1.22 μg/ ( kg·bw·d)，8岁以上人群通过摄入肉类食品的吉他霉素的膳食暴露量最大。中国居民通过摄入肉蛋乳等动物性食品暴露于吉他霉素，各年龄段CRQ均小于1。其中2～7岁人群CRQ值最高，风险最大；65岁以上人群CRQ值最低，风险最小。结论 中国居民通过摄入动物性食品的吉他霉素耐药性风险较低，危害程度较小，但儿童通过摄入乳制品的吉他霉素耐药性风险较高，有必要制定乳制品中吉他霉素残留的限量标准。
