烟雾病5 例临床分析

目的:研究烟雾病(moyamoya disease,MMD)的临床及影像学特征。方法:回顾性分析5例烟雾病患者,分析其临床及影像学特点。结果:本组病例既往均无阳性病史,中、青年起病,男性居多,均以缺血性脑血管病起病,肢体瘫痪不重,经颅多普勒(TCD)及头颅核磁改变明显,数字减影血管造影(DSA)检查均存在血管闭塞及侧支开放,烟雾血管网形成,1例MRA证实烟雾血管网形成。结论:对于无既往史的中、青年脑卒中患者,要考虑MMD的可能,需完善TCD、头核磁检寻找证据,最后完善数字减影血管造影确诊。     

降纤酶治疗偏头痛临床观察

目的：探讨降纤酶治疗偏头痛的疗效。方法：应用经颅多普勒血流诊断系统(TCD),随机选择60例脑血流速度加快偏头痛患者,分治疗组30例,应用降纤酶5u加入生理盐水250m1中静滴,每天1次,7—10天为1个疗程;对照组30例,应用尼莫地平6mg加入生理盐水250m1中静滴,每日1次,7—10天为1疗程。结果：治疗组总有效率86．7％,对照组总有效率36．7％。治疗组治疗前后TCD血流速度有明显改善,3个月内复发率明显降低。结论：降纤酶治疗偏头痛疗效确切,近期复发率低。     

Biogas generation apple pulp

In view of the pressing problem that appears in our region (Asturias, north of Spain) with the residues from the cider production, it was decided to test this kind of material as a co-substrate joint with slaughterhouse waste in a laboratory unit.     

70例颈椎病的TCD研究

目的:探讨颈椎病是否引起椎动脉(VA)的血液动力学异常。材料与方法:用TCD仪对70例颈椎病患者进行检查,指标:频谱、Vs、Vd、Vm、PI,与正常人组50人进行比较。结果:颈椎病组>40岁年龄组的指标与正常人相应年龄组差异显著(P<0.01～0.05),<40岁组无显著性差异(P>0.05),异常改变主要为单侧的VA,颈椎病组异常的VA通常有频谱的相应改变。结论:颈椎病患者TCD的改变一般为单侧的VA流速降低为主要特点。     

以经颅多普勒血流仪对蝮蛇抗栓酶与速效溶栓清治疗缺血性脑血管病颅内动脉血流变化的观察

６２例缺血性脑血管病患者,其中４２例为蝮蛇抗栓酶治疗组,２０例为速效溶栓清治疗组。治疗前后分别用经颅多普勒血流仪（ＴＣＤ）检查脑血管（大脑中动脉ＭＣＡ、前动脉ＡＣＡ及后动脉ＰＣＡ）血流平均值Ｖｍ。结果显示,两组患者被治疗后脑血管血流Ｖｍ均明显增高（Ｐ＜０．０５或Ｐ＜０．０１）,但两组间无显著性差异（Ｐ＞０．０５）。表明两种药物治疗缺血性脑血管病疗效相仿,但速效溶栓清价格较高

动态模式多普勒显示及其实验研究

动态模式多普勒仪是一种新型脑血流状况分析仪器。它采用波束方向上连续采样点的深度能量彩色编码直观地显示血流状况的二维信息，较业已成熟的经颅多普勒仪能够更加全面地获取和分析血流动力学参数，因而性能优越。本文结合经颅多普勒仪阐述动态模式显示的原理，对照频谱图介绍其显示方式和功能，并以显示实验来探索M-mode显示的实现方法。     

Neuroimaging in acute liver failure

Acute liver failure (ALF) is frequently complicated by the development of brain edema that can lead to intracranial hypertension and severe brain injury. Neuroimaging techniques allow a none-invasive assessment of brain tissue and cerebral hemodynamics by means of transcranial Doppler ultrasonography, magnetic resonance and nuclear imaging with radioligands. These methods have been very helpful to unravel the pathogenesis of this process and have been applied to patients and experimental models. They allow monitoring the outcome of patients with ALF and neurological manifestations. The increase in brain water can be detected by observing changes in brain volume and disturbances in diffusion weighted imaging. Neurometabolic changes are detected by magnetic resonance spectroscopy, which provides a pattern of abnormalities characterized by an increase in glutamine and a decrease in myo-inositol. Disturbances in cerebral blood flow are depicted by SPECT or PET and can be monitored and the bedside by assessing the characteristics of the waveform provided by transcranial Doppler ultrasonography. Neuroimaging methods, which are rapidly evolving, will undoubtedly lead to future diagnostic and therapeutic progress that could be very helpful for patients with ALF.
