某医科大学中老年教职工健康状况分析

对１００４名５０岁以上中老年教职工进行健康检查。结果：健康者仅占１１．２５％，而８８．７５％的中老年教职工至少患有１例次疾病，最多患有５例次疾病，总例次患病率为１８６．９５％，男女例次患病率分别为１８７．２４％和１８６．６２％，男女间无差异。前５位疾病的顺位是：心血管疾病、呼吸系疾病、脑血管疾病、消化系统病、泌尿生殖疾病。     

依托咪酯对豚鼠听诱发电位的影响

为探讨听诱发电位能否作为临床麻醉深度监测手段,采用非镇痛性麻醉药依托咪酯分次注入豚鼠腹腔,根据用药剂量模拟浅、中、深度麻醉,观察豚鼠听觉中潜伏期反应及听性脑干反应变化.结果显示,依托咪酯对听觉中潜伏期反应有明显抑制作用,且随麻醉深度加深而增强,但到一定深度后,出现“饱和”现象;中潜伏期反应谱峰明显向低频移动.依托咪酯对浅麻醉时听性脑干反应影响不显著,当麻醉加深时亦出现明显改变.提示中潜伏期反应及听性脑干反应结合使用,可以作为监测麻醉深度的客观电反应指标.

猕猴实验性脑动脉硬化扫描电镜观察

本实验表明,猕猴高脂造型22—28个月,其大脑中动脉(Middle Cerebral Artery:MCA)内皮发生水肿、细胞间隙变宽,局部破裂等改变,中膜平滑肌细胞增生、迁移。老年高脂组病损程度较重,且中央支也表现出类似改变。结果提示,高血脂可以引起脑动脉硬化性改变,且病损程度与年龄因素密切相关。     

Haemodynamic studies in early stroke

Summary We investigated prospectively a consecutive series of 81 patients suffering from acute middle cerebral artery (MCA) ischaemia by transcranial Doppler ultrasonography (TCD) within 24 h of the onset of symptoms. To monitor the haemodynamic changes follow-up recordings were carried out at short intervals during the next 2–3 weeks until stable haemodynamic status was achieved. In order to estimate the value of early TCD examinations in predicting the extent of brain damage seen later on, initial MCA flow reduction was correlated with infarction size and pattern on computed tomography. Fifty-three cases showed sufficient ultrasound penetration through the temporal bone. MCA flow asymmetries were recorded in 45 patients (85%); occlusion was observed in 17. Recanalization occurred in 11 patients followed by transient hyperaemia in 3, leaving residual stenosis in 2. Initial increase of flow velocities normalized within days or weeks in 7 out of 9 patients, while 2 developed residual MCA stenosis. Nineteen patients showed a considerable flow reduction on admission, which returned to normal in 9; transient hyperaemia was detected in 5 of these. Eight patients did not show any MCA flow asymmetry. Our study revealed very variable haemodynamic changes in acute stroke, which influenced further diagnostic and therapeutic management. The high rate of spontaneous recanalizations of MCA occlusions followed by transient hyperaemia in many cases has an important bearing on thrombolytic or theological therapy. Flow velocity differences could be related to infarction pattern rather than to infarction volume. Early MCA flow asymmetry recorded by TCD within the first 24 h could not reliably predict the extent of persistent brain damage or clinical outcome.     

大脑中动脉钙化的CT与经颅多普勒超声对照研究

目的探讨大脑中动脉（middle cerebral artery,MCA）水平段（M1）钙化的量化指标与血流动力学的关系。资料与方法搜集经头颅CT确诊M1段钙化且行经颅多普勒超声（transcranial Doppler,TCD）检查者41例,按有无钙化分为钙化组和无钙化组。分析MCA钙化组血流动力学参数与钙化量化指标是否有相关性;检验钙化组与无钙化组血流动力学参数及狭窄发生率的差异。结果MCA搏动指数（pulsatility index,PI）与钙化体积以及积分值呈线性相关;钙化组与无钙化组PI差异有统计学意义（P〈0.05）,但狭窄发生率差异无统计学意义（P〉0.05）。结论MCA钙化程度与TCD反映血管弹性的PI相关,但与反映狭窄程度的血流速度无相关性。     

中切口切开法重睑成形术

目的介绍一种简便有效，恢复快的中切口重睑成形术。详细阐述该方法的手术要点，重睑成形术所遵循的原则等。方法术前灵活定位，局部麻醉下做长15mm的小切口，去除切口内部分眼轮匝肌及睑板前脂肪．将上睑皮肤与睑板固定。结果采用中切口切开法重睑成形术180例，效果满意。结论中切口重睑成形术创伤小，恢复快，是一种简便有效的方法。术中应严格遵循无创操作，宁窄勿宽，对过度依赖额肌的患者，手术前后进行睁眼训练。
