失眠症患者心理防御机制与社会支持的相关研究

目的　探讨失眠症患者心理防御特征和社会支持 ,并分析两者的关系。方法　采用心理防御方式问卷 (DSQ )、社会支持评定量表 (SSRS)对失眠症患者和正常健康者各 5 0例进行评定。结果　患者组心理防御方式 (不成熟型、中间型防御因子和掩饰因子的因子分高 ,成熟防御因子分低 )和社会支持 (社会支持总分、主观支持分、对支持利用度低 )与对照组相比差异有显著性 (P <0 .0 5或 0 .0 1) ;相关分析发现 ,患者组不成熟防御机制与SSRS的支持总分、主观支持分、对支持利用度呈负相关 (P均 <0 .0 5 ) ,中间型防御机制与SSRS的主观支持呈负相关 (P <0 .0 5 )。结论　失眠症患者心理防御机制的成熟程度较正常人低 ,社会支持差 ,两者存在一定的关系。     

Event-related potential correlates of functional hearing loss: Reduced P3 amplitude with preserved Nl and N2 components in a unilateral case

Abstract A female patient exhibiting functional hearing loss in her left ear demonstrated reduced amplitude of P3 component in event-related potentials (ERP) to left monaural stimulation, with preserved N1 and N2 components to stimulation of either ear. This result suggested that stimuli in the affected ear were conducted successfully up to the auditory cortex but that further processing in higher brain regions was 'repressed'. Event-related potential examination for such hysterical disorders could be useful in clarifying their brain mechanism and offer a useful diagnostic clue to its nature.     

Health insurance and private providers: A study of the civil servants' medical benefit scheme in bangkok,Thailand

Compulsory health insurance schemes have received attention recently as a means of creating a reliable extra-budgetary source of health care funding. Yet, the full implications of such schemes in a developing country context are unclear; in particular, the impact on and relationship with private sector providers has infrequently been explored. This study examines patterns of public and private sector utilization under the Civil Servants' Medical Benefit Scheme (CSMBS) in Bangkok, Thailand. The CSMBS currently provides limited reimbursement for private inpatient care, but recent proposals suggest increasing benefit levels for care sought in the private sector. The study shows that despite high level of cost recovery in the public sector, charges were much lower than those in the private sector. Different patterns of diagnosis in the two sectors were found with private hospitals tending to treat a less complex case mix. Within the private sector, there was a limited tendency to specialize in certain types of care. It is concluded that under the current payment mechanism of fee-for-service reimbursement, measures to enhance access to private sector care should be approached with caution. In the long run, the scheme should merge with the recently established social security scheme.     

屈膝过程中的胫股运动特性分析

本文采用三维位移测量方法，测试１０例离体人膝标本的胫股关节三维运动特性。发现屈膝过程中，胫股运动也具有典型的三维运动特点。其中在屈膝初期的３０°内，胫骨内旋最明显并伴有胫骨内翻现象，平均内旋８°，内翻６－７ｍｍ，膝关节完全伸直时胫股扣锁使膝关节稳定，屈曲时胫股“解锁”使膝关节松弛，具重要的临床意义，同时提示，在解释传统的胫股扣锁现象时不应遗漏伴随发生的胫骨内／外翻现象。

Bilateral organized chronic subdural haematomas: High field magnetic resonance images and histological considerations

Summary The authors describe a 66-year-old man with progressive gait disturbance caused by bilateral organized chronic subdural haematomas. The characteristics of these lesions on magnetic resonance (MR) images have not yet been clarified. The organized haematoma in our patient exhibited slight hypo-intensity on T 1-weighted MR images and marked hypo-intensity on T 2-weighted MR images obtained at 1.5 T. Preoperative MR imaging may give us useful information about surgical strategy in the case of chronic subdural haematoma with an unusual appearance on computed tomographic (CT) scans.     

润滑油抗泡机理的研究 Ⅱ.助泡剂对泡沫倾向的影响及抗泡剂配伍性能

考察了各类添加剂在不同浓度、温度及不同基础油中的泡沫倾向,并测定了这些条件下体系的表面张力。从表面化学角度解释了添加剂对泡沫性质的影响,并通过对抗泡剂配伍性能的研究,验证了消泡机制:抗泡剂须具备高的表面活性才能吸附于泡膜表面,降低泡膜的表面粘弹性,改变膜的流变性能,从而起消泡作用。

Analysis of a decreased Na+ conductance by tumor necrosis factor in identified neurons of Aplysia kurodai.

The ionic mechanisms of the effect of extracellularly ejected recombinant human tumor necrosis factor-alpha (rhTNF-alpha) on the membrane of identified neurons R9 and R10 of Aplysia kurodai was investigated with conventional voltage-clamp, micropressure ejection, and ion substitution techniques. Micropressure-ejected rhTNF caused a marked hyperpolarization in the unclamped neuron. Clamping the same neuron at it resting potential level (-60 mV) and reejecting rhTNF-alpha with the same dose produced a slow outward current [Io (TNF)] associated with a decrease in input membrane conductance. Io (TNF) was decreased by depolarization and increased by hyperpolarization. The extrapolated reversal potential of Io (TNF) was approximately +10 mV. Ion substitution and pharmacological experiments suggest that Io (TNF) in identified neurons R9 and R10 of A. kurodai is due to a decreased Na+ conductance but not due to an activation of the Na(+)-K+ pump. Our results demonstrate that the immunomodulator TNF can act directly on the nervous system as well as on the immune system.     

精神分裂症患者心理防御机制与人格特征的相关性分析

目的　探讨精神分裂症患者心理防御方式和人格特片的特点及二者的相关性。方法　分别运用防御方式问卷 (DSQ)和艾森克个性问卷 (EPQ)对 10 1名精神分裂症患者和 30例正常人群进行防御方式评定和人格测定。结果　与正常对照组相比 ,精神分裂症患者更多采用不成熟和中间型防御方式 (P <0 0 5 )。防御方式与人格特征存在着一定的关联性 (P <0 0 5 )。不成熟型防御方式和中间型防御机制与EPQ的精神质 (P)得分和神经质 (N)得分呈显著正相关 (P <0 0 1) ,成熟防御机制与内外向(E)得分呈显著正相关 (P <0 0 5 )。结论　精神分裂症患者更多地使用不成熟防御机制 ,存在病态人格 ,且者之间存在明显相关性 ,有关结果 ,对于探讨精神分裂症患者的病理心理机制和开展心理治疗有指导意义。
