Observations on the efficacy of combined acupuncture and medicine in Treating 50 cases of pseudobulbar paralysis

目的：观察针药结合治疗假性延髓麻痹的疗效。方法：采用完全随机抽样法分为针刺组50例，对照组48例。针刺组在西医治疗的同时，应用针刺进行综合治疗；对照组单纯接受西医药物治疗。结果：针刺组有效率为92．0％，对照组为62．5％。两组疗效差异具有非常显著性意义（P〈0．01）。结论：针药结合治疗假性延髓麻痹效果明显优于单纯西药治疗。     

进展性卒中与脑动脉狭窄的脑血管造影研究

目的探讨进展性脑梗死的影像学特点及与脑动脉狭窄之间的相关性。方法选择我院29例进展性脑梗死患者并与同期收治的31例完全性脑梗死患者比较,所有患者均行头颅MRI (或头颅CT)及脑血管造影检查(DSA检查),分析进展性脑梗死的影像特点及其与脑动脉狭窄的相关性。结果进展性脑梗死组分水岭脑硬死或侧脑室体旁梗死发生率72．4％(21／29)及脑动脉狭窄发生率75．86%(22／29)均明显高于完全性脑梗死组22．6％(7／31),35．48％(11／31)。进展性脑梗死组中重度狭窄发生率为55．17％(16／29),高于完全性脑硬死组的12．90%(4／31)。溃疡性斑块发生率在进展性脑梗死组48．28%(14／29)高于完全性脑梗死组16．13％(5／31)。结论中重度脑动脉狭窄及溃疡是进展性卒中的重要危险因素,应早期检查及处理脑动态狭窄以防止病情进展。     

中青年脑梗死68例临床分析

脑梗死多见于老年人，但近年来中青年（16-45岁）患者逐渐增多且有年轻化趋势，深人探讨中青年脑梗死的致病因素及临床表现对其防治有重要意义。本文回顾性分析了我院自1998年1月到2004年12月问收治的中青年脑梗死患者68例，现报告如下。     

大鼠静脉窦高压致硬膜血管变化的研究

目的探讨大鼠静脉窦高压后硬膜血管变化及其静脉窦高压在硬脑膜动静脉瘘形成中的作用。方法体重200～250g的SD雄性大鼠110只,随机分为静脉窦高压组(85只)和假手术组(25只),将静脉窦高压组85只大鼠闭塞左侧横窦和上矢状窦前1／3,并吻合右侧颈总动脉和颈外静脉,制成静脉窦高压模型。假手术组大鼠单纯解剖相应的颈部血管和硬脑膜窦,但不行吻合或闭塞。术后90d,随机取7只静脉窦高压组大鼠和5只假手术组大鼠,行硬脑膜血管明胶墨汁灌注,观察硬膜血管的状况。结果术后90d静脉窦高压组和假手术组大鼠的硬膜血管数分别为(10.7±1.5)条／mm,(10.3±0.6)条／mm,差异无显著性。在静脉窦高压组中1只大鼠有硬脑膜动静脉瘘,其形态和结构与生理性动静脉短路类似。结论大鼠静脉窦高压一段时间后,颅内硬膜血管无明显增生。颅内硬脑膜动静脉瘘的形成很可能是由动静脉间的短路发展而来。     

血栓的形成及中药抗栓溶栓概况

血栓形成是由于正常的凝血机制的扰乱而促使某些血细胞和蛋白质被激活相互作用而最终导致血小板－纤维蛋白血栓的形成．ＡＴ－Ⅲ、ＰＣ、ＴＭ是体内重要的抗凝物质．白细胞与血小板的相互作用、ＰＧＩ２／ＴＸＡ２值以及许多疾病状态是影响血栓形成的诸因素．许多中药具有抗血小板聚集、抗血栓形成的作用，包括生物碱类，如小檗碱、北豆根碱和钩藤碱；中药蒲黄、花椒、沙棘、大蒜的提取物；一些中药复方等．     

Co-localization of vasoactive intestinal polypeptide, γ-aminobutyric acid and choline acetyltransferase in neocortical interneurons of the adult rat

Interneurons immunoreactive for vasoactive intestinal polypeptide (VIP) are integral elements of columnar organization patterns in the rat cerebral cortex. By application of the sensitive mirror technique, the co-localization of VIP with the classical inhibitory neurotransmitter γ-aminobutyric acid (GABA) and the acetylcholine-synthesizing enzyme, choline acetyltransferase (ChAT), was investigated in neocortical neurons. Furthermore, the frequency of co-localization of ChAT with GABA was determined. In a sample of 118 VIP-immunoreactive neurons, mostly from the primary somatosensory cortex, it was demonstrated that virtually all of them reveal immunoreactivity for GABA and, therefore, are to be GABAergic. Moreover, 34% of mostly bipolar, VIP-positive neurons contained ChAT and are, thus, supposedly cholinergic as well. Co-localization of VIP and ChAT varied according to cortical laminae. Finally, 88% of a total of 60 ChAT-immunoreactive neurons were also immunostained for GABA. It is concluded that almost all VIP-immunoreactive neurons and most of the cholinergic neurons in rat neocortex represent partly overlapping subpopulations of inhibitory interneurons utilizing GABA.     

缺氧缺血性脑病新生鼠补钙前后脑细胞,红细胞内外钙的变化

为了观察一般剂量补钙对缺氧缺血性脑病（ＨＩＥ）脑细胞和红细胞内外钙变化的影响，以探讨ＨＩＥ时补钙是否增加脑细胞钙超载，用ＨＩＥ新生动物模型进行了实验研究，结果表明：（１）缺氧缺血时红细胞、脑细胞及脑组织出现钙积聚；（２）补钙后，血浆总钙浓度明显升高，而脑细胞、脑组织及红细胞钙积聚并未加重；（３）血浆总钙浓度与脑细胞或红细胞胞浆游离钙离子浓度无相关关系。提示：（１）ＨＩＥ时钙内流可能是全身性的；（２）对ＨＩＥ并低钙血症患儿吸氧后一般剂量补钙可能是安全的。

Statistical analysis of gait patterns of persons with cerebral palsy

Patients at Boston's Children's Hospital diagnosed as having cerebral palsy were filmed walking. These films were digitized and translated into measurements associated with leg motion. In this paper we use the gait measurements of 128 such patients to illustrate that the kth nearest neighbour clustering procedure results in a gait typology for patients with cerebral palsy. The procedure identifies four subpopulations from the sample data; the membership of a patient within this typology is mostly determined by the patient's motor control. The developed typology differs from the present diagnostic system which classifies a cerebral palsy patient as either quadriplegic, diaplegic or hemiplegic.
