Objective To explore the teaching ability of the neurology refresher doctors by case teaching method combined with flipped classroom teaching mode. Methods The refresher doctors who were studying in the infection group of Department of Neurology, Xuanwu Hospital Capital Medical University between March 2019 and September 2020 were selected. According to the time of admission, the enrolled refresher doctors were divided into control group (grade 2019) and observation group (grade 2020). The control group adopted the traditional teaching mode, and the observation group adopted the case teaching method combined with the flipped classroom teaching mode. A self-designed questionnaire was used to compare the teaching ability of the two groups of refresher doctors. Results A total of 44 refresher doctors were included. Among them, there were 24 refresher doctors in the control group and 20 refresher doctors in the observation group. The self-evaluation of the teaching ability of the two groups of refresher doctors and the evaluation of their teaching ability by the teachers showed that, except for the item “enthusiasm for teaching and willingness to spend enough time to participate in the evaluation of teaching work” of humanistic quality (P>0.05), the observation group was better than the control group in professional knowledge, teaching ability, teaching methods and humanistic quality (P<0.05). Conclusions Through the case teaching method combined with flipped classroom teaching mode, the teaching ability of refresher doctors can be cultivated, which is helpful for training more high-quality doctors for the country and promoting the sustainable and coordinated development of medical education. However, the awareness and enthusiasm of the refresher doctors to teaching work need to be improved.
【摘要】 目的 通过比较遗忘型轻度认知障碍（amnestic mild cognitive impairment，aMCI）和血管性认知障碍非痴呆型（vascular cognitive impairment-no dementia，VCI-ND）患者及正常老年人群在简易智能精神状态检查量表（mini mental state examination，MMSE）、听觉词语学习测验（auditory verbal learning test，AVLT）、画钟试验（clock drawing test，CDT）及临床痴呆评定量表（clinical dementia rating scales，CDR）中的表现，进一步分析aMCI和VCI-ND在认知损害方面的不同特点。 方法 选取首都医科大学宣武医院神经内科门诊收治aMCI患者23例及VCI-ND患者27例（CDR＝0.5分），同时选取40名正常老年人（CDR=0分）作为对照组。每位受试者均进行MMSE、AVLT、CDT及CDR等神经心理学量表测查，分析以上3组被试各项神经心理学测查得分之间的差异。 结果 各组受试者的年龄、性别及受教育程度差异无统计学意义（Pgt;0.05），具有可比性。aMCI和VCI-ND组在MMSE、CDT、即刻记忆、延迟记忆及延迟再认检测中的平均值均低于对照组，且差异均具有统计学意义（Plt;0.05）。aMCI和VCI-ND两组除延迟再认检测外，其余各项测查的平均分均无统计学意义（Pgt;0.05）。在延迟再认检测中，aMCI组（6.65±4.00）较VCI-ND组（8.67±2.76）再认词语数量少，两组延迟再认的得分均低于对照组（12.83±1.77），差异有统计学意义（Plt;0.05）。 结论 aMCI和VCI-ND在记忆力、执行能力和信息处理能力方面较正常老年人均有所损害。由于aMCI和VCI-ND不同的病理改变，导致患者存在不同类型的记忆储存和提取机制。【Abstract】 Objective To investigate the different patterns of cognitive impairment in patients with amnestic mild cognitive impairment (amci), vascular cognitive impairment-no dementia (VCI-ND) and normal elder people. Methods A total of 23 patients with aMCI and 27 patients with VCI-ND (CDR＝0.5) and another 40 healthy elder people (CDR=0) were selected. Each individual underwent the neuropsychological tests, including mini mental state examination (MMSE), auditory verbal learning test (AVLT), clock drawing test (CDT), clinical dementia rating scales (CDR) and hamilton rating scale for depression (HAMD). The differences between the three groups were analyzed. Results The differences in age, sexes, and the education background among the three groups were not significant (Pgt;0.05) which meant comparability. The mean scores of MMSE, CDT, instant memory and delayed awareness in aMCI and VIC-ND group were much lower than that in the control group (Plt;0.05). The differences in all the test items except for delayed awareness between aMCI group and VCI-ND groups were not significant (Pgt;0.05). However, in the recall recognition test, these three groups had significant differences: the score in patients with aMCI (6.65±4.00) was much lower than that in patients with VCI-ND (8.67±2.76; Plt;0.05), and the scores of the two groups were both lower than that in the normal aging group (12.83±1.77; Plt;0.05). Conclusion Compared with normal elder people, the cognition of aMCI and VCI-ND patients is impaired severely. The memory tests suggeste that compared with aMCI patients, VCI-ND patients may have different neuropathological changes leading to different mechanism of memory encoding and retrieval.
