AN EEG STUDY OF 120 EPILEPTIC FAMILIES

To study the epilepsy heredity, routine EEG tracings of 120 epileptic families and 57 normal control families were carried out. The results suggest that epilepsy shows an obvious tendency to be inherited.     

Gamma-hydroxybutyrate hyperpolarizes hippocampal neurones by activating GABAB receptors.

gamma-Hydroxybutyrate, a naturally occurring substance present in the mammalian central nervous system caused a dose-dependent (0.25-10 mM) hyperpolarization and small membrane conductance increase when applied to hippocampal CA1 pyramidal neurones in vitro. This action was reversibly inhibited by the GABAB antagonist, CGP 35348 (20-100 microM) and divalent cations, Zn2+ and Ba2+, but not by the GABAA antagonist bicuculline (50 microM). These results suggest that GABAB receptors may mediate the actions of gamma-hydroxybutyrate.     

钙剂加维生素D治疗对糖尿病患者钙代谢的影响

本文报道NIDDM患者在常规治疗的基础上加用钙剂和维生素D治疗后的钙代谢变化。糖尿病患者单纯用常规治疗控制血糖后,负钙平衡不能完全纠正,而加用钙剂和维生素D治疗后,负钙平衡能完全纠正,并且高于正常对照组平衡值(P<0.01)。说明钙剂加维生素D治疗对糖尿病性骨质疏松是有益的。

超顺磁性氧化铁Resovist标记神经干细胞的实验研究

目的研究超顺磁性氧化铁（superparamgnetic iron oxides，SPIOs）标记神经干细胞及其生物学特性．方法：神经干细胞培养、传代和诱导分化；Resovist（一种SPIOs）标记神经干细胞。制备磁标记神经干细胞；利用免疫细胞化学、透射电镜和Prussian blue染色等方法对磁标记神经干细胞生物学特性进行研究。结果：在原代及传代细胞中有Nestin阳性细胞即神经干细胞．血清诱导下，神经干细胞可分化为GFAP、NF200阳性细胞．Resovist与神经干细胞共同孵育后，透射电镜及Prussian blue染色显示胞浆中含有铁颗粒，Resovist也可以随细胞的分裂增殖而传到子代细胞中。随Resovist浓度的增高（5．6μg／ml-11．2μg/ml），Resovist对神经干细胞存活、分化能力的影响无显著性差异（P〉0．05）．当Resovist的浓度大于22．4μg／ml时。Resovist影响其存活和分化（P〈0．05）。结论：本实验利用Resovist作为磁标记探针，对神经干细胞进行成功磁标记，为进一步利用核磁共振（MRI）对神经干细胞活体追踪奠定实验基础。     

舒张功能障碍对冠心病的诊断价值

目的应用超声多普勒方法评价冠心病患者的左室整体舒张功能及舒张功能障碍的发生率，探讨舒张功能障碍在冠心病无创诊断中的价值。方法对入选病人行常规检查，同时进行二尖瓣血流频谱、肺静脉血流频谱及二尖瓣环组织多普勒检查，对比临床标准与舒张功能障碍标准对冠心病的诊断率。结果舒张功能障碍标准对冠心病的检出率显著高于临床标准。结论舒张功能检查可作为冠心病诊断的初筛检查。     

泌尿外科手助腹腔镜手术的进展

外科手术发展至今可分为三代:第一代为开放手术(open surgery);第二代为腹腔镜手术(laparoscop-ic surgery),其又可分为三个技术平台,包括标准腹腔镜手术(purelaparoscopic surgery或standardlap-aroscopic surgery)、手助腹腔镜手术(hand-assistedlaparoscopic surgery)和针式     

浅谈胡澍手校本《素问》的文献版本价值

清末经学家和小学家胡澍把《素问》作为子书之一，博采众本，悉心校勘，以小学的方法进行专门研究，撰成《素问校义》，为研习《内经》不可不读之书。通过对天津中医药大学图书馆所藏胡澍手校本《重广补注黄帝内经素问》的考证，发现胡澍校勘所据底本一直被误作宋本，而实是明顾从德影宋刻本．校勘工作历时数年，手校本《素问》留有胡澍悉心对校后所做出的千余条校语，可惜草创未就，他便英年早逝。手校本这第一手资料，对研究胡澍的治学思想和《素问校义》的成书过程，学习和掌握知识，传承弘扬学术，都具有重女的文献参考价值。     

显微镜下直切口锁孔微创治疗高血压性脑出血

目的探讨显微镜下直切口锁孔微创治疗高血压性脑出血的价值。方法根据CT提示血肿在头皮的投影设计手术切口部位，通过4～5cm皮肤直切口，直径2cm的骨窗，切开皮层到达血肿腔清除血肿。结果血肿完全清除17例，18例清除率达到90％，4例清除率达到80％。术后再出血2例。4例术后3周内死亡：2例死于循环呼吸功能衰竭，1例死于脑干功能衰竭，1例死于消化道出血，手术死亡率10．2％（4／39）。35例随访0．5—3年，平均2．1年，术后6个月ADL分级：1级9例，2级12例，3级9例，4级4例，5级1例，死亡4例。结论显微镜下直切口锁孔微创技术是一种快速、有效和安全的治疗高血压性脑出血的手术方法，可以解除血肿的占位压迫效应，有效止血，防止再出血，效果满意。     

Systemic Antiinflammatory Corticosteroid Reduces Mechanical Pain Behavior, Sympathetic Sprouting, and Elevation of Proinflammatory Cytokines in a Rat Model of Neuropathic Pain

Background: Chronic pain models are commonly defined as either nerve-injury or inflammation models, but recent work suggests inflammatory processes are important in nerve injury-induced pain.

Methods: In the rat spinal nerve ligation model, the authors examined effects of systemic corticosteroid triamcinolone acetonide (TA) on the cytokine protein profile and sympathetic sprouting in the axotomized sensory ganglia, excitability of sensory neurons, and mechanical sensitivity.

Results: By postoperative day 3, marked increases (5- to 16-fold) in monocyte chemoattractant protein-1, growth-related oncogene (GRO/KC or CXCL1), and interleukin (IL)-6 were observed, whereas IL-4 and IL-2 levels fell more than fourfold. The increased cytokines and number of sympathetic basket formations in the sensory ganglia were reduced toward normal values by TA given starting at the time of injury. Interleukin-4 and IL-2 levels were not restored by TA. Systemic TA also reduced the firing rate and incidence of bursting activity, but not the overall incidence of spontaneous activity, in large- and medium-sized neurons. Mechanical hypersensitivity on postoperative day 3 was reduced by TA, and some effect could still be observed 4 days after cessation of TA. However, starting TA at day 7 was ineffective.
