Neuronal plasticity in memory and learning abilities: Theoretical position and selective review

Neural plasticity of modality-nonspecific and modality-specific memory and learning abilities pertains to fluid intelligence and crystallized intelligence, respectively. The limbic system with the novelty neurons of the hippocampus interacts with the prefrontal cortex optimization of the orienting reflex and voluntary attention. Brain-derived neurotrophic factor produced by novelty neurons of the hippocampus contributes to long-term memory formation and improves learning abilities in a wide range of disciplines. Synergistic combination of stimulation with “analytical-specific visual perceptual patterns” and “optimally high” physiological activation of the bilateral electrodermal system optimizes the limbic system and prefrontal cortex activity as demonstrated by enhanced prefrontal N450 ERPs to a memory workload paradigm. This is accompanied by improvements in auditory retention tasks, word memorization, higher school achievement and marks, and an amelioration of “analytical-specific perceptual skills” as measured by the Mangina-Test. Intracerebral ERPs to a memory workload paradigm contributed to the elucidation of limbic structures and neocortical sites involved in memory workload processes. The progressive degeneration of these same structures causes the gradual decline of memory functions observed in early Alzheimer's disease. Research findings indicate that ERPs elicited by a memory workload paradigm are sensitive markers for diagnosis, treatment and clinical follow-up of early Alzheimer's patients. In addition, ERPs provide objective measurement of cholinergic medication effects on cerebral functions involved in memory processes through neuropsychophysiological parameters.

用秩和比法对我院的10个公示病种医疗质量进行综合评价

目的对我院2005年度公示的10个病种进行医疗质量综合评价。方法采用秩和比法(RSR)进行统计分析。结果我院的10个公示病种被划分成4个医疗质量等级:老年性白内障、小儿支气管肺炎2个病种质量为优,急性阑尾炎、腹股沟疝(单侧)、子宫平滑肌瘤、剖宫产4个病种质量为良,胃大切、脑梗塞、急性心肌梗塞3个病种质量为中,脑出血1个病种质量为差。结论通过对综合指数秩和比(RSR)的计算并根据其值分级归档,反映出所研究病种之间存在着医疗质量高低的差异。控制和降低本院临床常见病种的医药费用,进行医疗全程连续性控制,为患者提供经济有效的医疗服务。     

应重视口腔颌面部恶性肿瘤的综合序列治疗

口腔颌面部恶性肿瘤约占全身恶性肿瘤的3％，虽然所占比例不高，但l大l其解剖部位特殊．涉及美观和重要的生理功能，冈此对患者机体和心理的影响不容忽视。早期（Ⅰ、Ⅱ期）口腔颌面部恶性肿瘤无论采用手术和（或）放射治疗，均能取得良好效果。但遗憾的是，大多数患者就诊时，已属局部一区域晚期（Ⅲ、Ⅳ期）。由于受到局部解剖和维持功能的限制，单纯通过扩大手术切除范围和改进现有手术技术，除能改善患者生存质量外，已无法提高此类患者的生存率，延长其生存时间。     

多站点综合性毕业考试的改革与实践

我校改革临床医学专业毕业考试模式与方法，在临床实习过程中组织多站点综合性考试，采用闭卷笔试方法考核临床理论知识，占70％；采用实践操作与现场口试方法考核临床技能及相关知识，占20％；采用开卷笔试方法考核医疗文书书写，占10％。实践证明，此项改革能促进医学生端正实习态度，调动实习的积极性与主动性，引导医学生在实习中重视理论学习与临床实践的密切结合，促进临床教学质量的提高。     

Mothers' discrimination of their neonates' cry in relation to cry acoustics: The first week of life

This study investigated the temporal evolution in the discrimination of the newborn's crying by the mother, from the first to the eighth day after birth. The sample included twenty human mothers who had had an uneventful pregnancy, labour and delivery. They were asked to identify the spontaneous cries of their newborn babies from tape-recorded cries containing cries from their own newborn and from three other newborns. On the first day, the percentage of correct answers was 48#pc, then 81 #pc on the eighth day. Two acoustic features that may underlie this discrimination were analyzed: the maximum Fo values and the average number of cry bursts per second. On the seventh day, these two acoustic variables and the discrimination abilities significantly correlate.

试论新世纪初期医院综合院力评价

作者阐述了医院综合院力的内涵与提出背景，提出了新世纪初期综合院力的评价内容体系，即一级评价内容7项，二级评价内容39项，三级评价内容15l项，并就各指标评价内容进行了讨论分析。     

医院综合效益评价中的权数（三）——估计权数

在医院综合效益评价中，估计权数由评价专家根据经验对评价指标的重要程度的一种评估，这类数据通常用的ＡＨＰ法进行处理。本文用ＡＨＰ的递推算法计算估计权数，这种算法不仅计算简单，而且易达到一致性的要求，其估计的剩余误差小于ＡＨＰ法。
