Advance in Functional Restoration of Injured Nerve with Low Level Laser and its Utilization in the Dental and Maxillofacial Region

The inferior alveolar nerve and facial nerve are the two most important nerves in the dental and maxillofacial region. The injury to them is one of the major postoperative complications after alveolar surgery and orthognathic surgery. However, recovering the nerve function after injury takes a long time and the recovery effect tends to be unsatisfactory. In recent years, an intensively investigated technique, low level laser which has been applying in assisting the recovery of nerve function, has been gradually proved to be effective in clinically treating postoperative nerve injury. In this article we review in terms of the mechanisms involved in low level laser-assisted functional restoration of nerve injury and its clinical application in the recovery of nerve function in the dental and maxillofacial area as well.     

家长对小学生近视的知信行分析

目的 了解保定市小学生家长关于小学生近视知信行的相关现状及影响因素,制定有效干预措施,为预防儿童青少年近视提供有力依据。方法 运用分层整群随机抽样的方法,抽取保定市某小学一年级至六年级766名学生家长进行问卷调查。结果 小学生家长用眼卫生相关知识总正确率为64.90%。家长年龄越大、文化程度越高以及自身近视的家长掌握小学生近视的相关知识越多。家长年龄越大,督导孩子健康用眼的行为越易发生(P=0.027,OR=0.169)。结论 应多渠道对学生家长进行健康教育,为控制和预防小学生近视的发生与发展构建以家庭为主的第一道防线。     

工作坊模式在护生压疮护理带教中的应用效果分析

目的探讨工作坊模式在护生压疮护理带教中的应用效果,为临床护理带教提供参考。方法选取2018年7月—2019年6月在医院实习的120名护生作为研究对象,随机分为对照组和观察组,各60名护生。对照组采用传统带教法进行压疮培训,观察组采用工作坊教学模式进行培训。培训结束后比较两组护生压疮知识的掌握程度即理论考核、技能操作成绩,教学效果满意度。结果观察组护生对压疮知识的掌握程度即理论考核成绩、技能操作考核成绩远远高于对照组,两组差异具有统计学意义(P<0.05)。95%的观察组护生对工作坊教学模式的效果表示满意,认为工作坊教学模式能够提高学习的兴趣、主动性和临床实践能力,对临床工作有很大帮助。结论工作坊教学模式应用于压疮护理的临床带教,能让护生亲身体验压疮护理的过程,并参与其中,将理论与实践相结合,更好地活跃课堂气氛,启发护生思考,提高护生对压疮理论和技能的掌握,为临床实际工作中压疮护理质量的提高奠定基础。     

责任指数对口腔医学专业学生职业精神考核的设想

医学生的责任心体现在其一定行为表现上，是医学生职业精神培养的重要内涵，因此对影响医学生责任心的负向行为进行一定的干预具有重要意义。分析国内外医学院校应用责任指数考核在医学生行为督导养成的评价研究，遵循我国口腔医学专业人才培养的规律，结合口腔医学生成长的特点，借鉴职业精神考核的相关指标——责任指数考核法，试设计口腔医学生行为责任指数测评方案，并预设可行性，为拓宽口腔医学生职业精神的培养提供思路。     

How Do Students Source and Supply Drugs? Characteristics of the University Illegal Drug Trade

Background: It is widely known that a proportion of university students use drugs. However, much less is known about how they source and supply their drugs. Objectives: In this article, we investigate student drug trading activity, including how they obtained their drugs, whether they sold drugs, and the extent to which their drug trading might be described as a form of “social supply”. Methods: A survey was conducted of all students across seven of the nine universities of Wales. In total, 7855 students submitted a questionnaire and 1877 of these reported drug use in the current academic year. All students who reported using one or more illegal drugs in the current academic year were asked how they obtained their drugs, how they funded their drug use, whether they had sold, traded or given away illegal drugs, along with their motives for drug trading. Results: The results showed that about half of users obtained drugs solely from friends and associates and one-fifth obtained them solely from external dealers. One-quarter used friends and associates as well as external markets. In many cases, supplying drugs amounted to sharing them or giving them away. However, over one-third of students said that they had sold drugs. Conclusions: Overall, the methods of sourcing and supplying drug among university students shares features of both “social supply” and “traditional” drug markets. We conclude that the student drug market investigated is best described as a “hybrid” combination of both.
