基于超星学习通+直播+团队探究学习的解剖学混合式教学实践*

自2019年年底新型冠状病毒疫情爆发以来,教育部发出"停课不停学、停课不停教"的号召,本文在此背景下,以混合式教学理念为基础,基于超星学习通平台进行《系统解剖学》在线课程资源建设,教师利用腾讯会议平台搭建直播课堂,然后每个小组发起单独的腾讯会议,适当增加分组讨论活动,进行团队探究式学习.     

抗疫背景下人体解剖学在线教学的探索与实践

依据新型冠状病毒肺炎防控统一部署,2020年上半年各高校充分利用在线慕课和省、校两级优质网络课程,实现"停课不停教、停课不停学"[1],在线教学既带来挑战,又推动了教学理念、教学技术和教学方法的变革.作为医学专业的基础入门形态学科,人体解剖与组织胚胎学学习效果的好坏对今后医学课程的学习有着至关重要的影响[2],为了提高在线教学质量,我们借助智慧平台和网络课程资源,结合课程特色,构建教学新模式,探索教学新方法,取得了积极成效.     

“免疫学在线教学”专题论坛征稿通知

正当前疫情形势下,为响应教育部"停课不停学"号召,全国高等院校均开展了在线教学,成效显著。为搭建在线教学交流平台,推动高校免疫学教学模式创新,保障我国免疫学人才队伍建设,我刊拟组建"免疫学在线教学"专题论坛,现就具体事宜说明如下。     

非临床专业解剖学线上教学的效果分析与思考*

为有效应对疫情,确保疫情防控期间"停课不停学"[1-4],重庆医科大学积极开展疫情期间线上教学工作.非临床专业的解剖学学时少,本教研室结合其教学目标制定了全新的线上教学模式,并积累了一些经验.在后疫情时代,对于这些专业,仍延续线上教学为主的教学模式.现将本教研室在疫情期间线上课程建设的过程及存在的问题进行浅析,供同行参考.     

新冠疫情背景下组织学与胚胎学网络教学的实施及教学反思*

2020年1月,突发的新冠肺炎疫情给我国经济社会发展带来巨大的挑战,能否将信息技术和网络教学完美融合,确保网络教学的质量,是摆在每一位教育工作者面前的问题[1].按照国家关于新型冠状病毒肺炎疫情防控工作部署要求,遵循"停课不停教、停课不停学"的原则,在2020年春季学期面向本校中医学、针灸推拿学、临床医学等专业开设组织学与胚胎学课程的网络教学.组织学与胚胎学是医学院校中非常重要的专业基础课,与现代医学及生命科学相互交叉与渗透,该学科研究的是正常人体的微观结构及功能,具有教学内容多、知识点繁杂、专业术语多、教学学时偏少、学生学习难度较高等特点[2].     

疫情阶段"停课不停学",学生如何更好地学习

为应对2020年新型冠状病毒肺炎重大突发卫生事件,疫情防控期间各地高校纷纷利用网络信息化手段开展"停课不停学"的线上教学,开启了一场教学方式的新革命。但相对于传统的线下课堂教学,新的教学方式出现了一系列限制和弊端。作为学生,在面对这些问题时,要做好充分的准备,调节好自己的状态,加强自我管理,"停课不停学",完成此次疫情期间的学习任务。

组织学胚胎学课程直播教学质量管控体系探索*

2019～2020学年春季学期因受新型冠状病毒肺炎疫情影响后,教育部下发通知要求"停课不停学",各类院校开始大规模线上直播教学[1].组织学胚胎学是一门重要的基础医学课程,主要研究人体微细结构及相关功能的科学,具有一定的抽象性[2, 3].在开始直播教学前,本校教务处要求保证直播教学质量,达到线下教学同等培养目标.直播教学质量的保证要求教师对培养对象在培养过程中达到培养目标,质量管控要贯穿整个教学过程[4-5].     

让孩子从小就拥有足够的安全感

小雨是小学四年级的男生，因为经常动手打同学，被学校停课，老师建议家长带他来看心理咨询师。     

Level of functioning of siblings and parents of probands of varying degrees of retardation

A further analysis of already published data supports the position that retardates of low ability level less frequently have retarded siblings, retarded parents, and parents low in occupational level than do retardates higher in ability level. The analysis supports the position that there are two types of retarded individuals, persons retarded as a result of gene or chromosomal anomalies, brain injury, etc., who more frequently occur in the lower-level retardate group, and persons whose retardation represents polygenic segregation, who more frequently occur in the higher-level group.     

Recovery of responsiveness of cells of lateral geniculate nucleus of rat

1. Recovery of responsiveness of single cells in lateral geniculate nucleus of rat has been determined in both P and I cells. There are three types of recovery curve among P cells; (a) early recovery, (b) early partial recovery followed by depression and then complete recovery, (c) prolonged depression followed by cyclic recovery. Type (c) is by far the commonest recovery curve. In contrast to the spike in a P cell, the synaptic potential recovers to its full amplitude in about 20 msec. All I cells exhibit similar rapid recovery curves after a prolonged depression.2. Conditioning stimuli applied to visual cortex also produce a prolonged depression in most P cells but I cells can be re-excited at short intervals from cortex. Decortication does not prevent the prolonged depression of the multineuronal response produced by optic nerve stimulation.3. A neuronal model is proposed to explain these observations. It is supposed that I cells (interneurones) are innervated by axon collaterals of the P cells (principal cells, projecting to visual cortex) and that the I cells exert an inhibitory influence on the P cells.     

Modes of Inheritance of Errors of Refraction

Eighteen families in which both parents had refractions within the range of +4·0 D to −4·0 D and axial lengths seen in emmetropia (22·3-26·0 mm) showed coefficients of correlation of the order 0·5 indicative of polygenic inheritance. Such coefficients were seen for axial length (0·407) and for the cornea (0·487), but not for the lens (which is known to be yoked to the axial length). No such coefficients were seen in 19 families in which one of the parents had axial length outside the emmetropic range (nine families with long axes and 10 with short axes).

The pattern of polygenic inheritance for emmetropia (completely correlated optical components) and errors of refraction up to 4·0 D (inadequately correlated components: correlation ametropia) follows that seen in stature and other measurable characters. In contrast the high refractive errors with their abnormal axial lengths (component ametropia) are—like the extremes in stature—pathological anomalies with monofactorial inheritance.

     

Evaluation of antibacterial activity of extracts of five species of wood-colonizing fungi

Screening new organisms for antibacterial activity and searching for new antibacterial drugs is important due to the constant generation of new antibiotic-resistant strains of pathogenic bacteria. An E. coli broth microdilution test was used to evaluate the results of the Vibrio fischeri bioluminescence test in five of the most antibacterially active species of wood-colonizing fungi. Serpula lacrymans was found to be a potential source of thermostable antibiotic(s) and the Vibrio fischeri bioluminescence test was confirmed to be a useful method for screening for antibacterial activity.
