眩晕是目眩和头晕的总称，以眼花、视物不清和昏暗发黑为眩，以视物旋转，或天旋地转视物旋转为晕，因两者常同时并见，故称眩晕。     

全自动血培养仪的临床应用及评价

目的评价全自动血培养仪 (BACTEC90 5 0 )临床应用情况。方法对BACTEC90 5 0全自动血培养仪检测的 4 6 8份标本 ,捡出阳性的时间、细菌种类及阳性率进行了评估。结果BACTEC90 5 0最短检出时间 4小时 ,最长 96小时 ,2 4小时以内阳性率为 6 0 .8% ,4 8小时以内阳性率 82 .4 % ,72小时以内阳性率 94 .1% ,细菌种类 12种 ,阳性 10。 9%。结论BACTEC90 5 0无论从出现阳性的时间、检出细菌种类和阳性率均明显高于本室往年传统方法的结果 ,而且操作简便、结果快速、准确。     

流行性乙型脑炎特异性IgM(ELISA)诊断试剂盒的改进和应用

流行性乙型脑炎夏秋季发病 ,与中毒性痢疾等其他脑部疾患易相混 ,仅靠临床症状诊断 ,可靠性差 ,易延误治疗 ,造成后患。因此 ,我们改进了乙型脑炎特异性IgM诊断试剂盒 ,缩短时间 ,当天抽血 10 0min内即可出报告 ,在短时间内 ,为临床提供可靠依据。     

升主动脉成形术中期效果分析

Objective Reduction ascending aortoplasty is an alternative procdure to the replacement of the ascending aorts in case of ascending aorta dilation. However,its applicabikity is still under debate.This retrospective study was designed to evaluuate the midterm follow-up of unsupported ascending reduction aortoplasty for of the ascending aorta in petients with aortic valve dis- ease.Methods From October ,1996 to April,2007, a total of 54 patients with aortic valve disease and dilatation of the ascending aorta underwent unsupported reduction aortoplasty in combination with aortic valve replacement at our institution The diameter of the ascending aorta was measyred before and early after sugery and then later between 13 and 96 menths [mean (23 ±16)months] posto- perativeiy using echocardiography.Results Two patients were dead with thean overall perioperative mortality rate was of 3.7%. The reduction aortoplasty decreased the diameter of the aorta from (45.77±6.02) mm p～eope～afive]y to (34.67 ～4.81) mm early after surgery (P<0.01). During follow-up, the diameter d aorta increased from (34.67±4.81) mm early after surgery to (37.65± 6.35) mm after a mean follow-up of (23±16) months (P<0.01), including the diameters are greater than > 45 mm within 5 pa- tients. Aortic stenosis and an early postoperative diameter greater than 40 mm m'e independent risk factors for redilatation. Conchusion Because of the unsatisfied midterm follow-up redilation of unsupported reduction aortoplasty for dilation of the ascending aorta with aortic valve disease, this group of patients needs continued intimate fallow-up or even reoperation. The patients of stenosis is the surtable indication for RAA, and it is necessary to reduce the diameter of aorta to be lees than 40 mm to prevent redilation.     

混沌理论在癫研究中的应用

1引言人类脑电活动的混沌特性具有神经生理基础,神经元是高度非线性组织,他们通过突触相互连接在一起,形成一个巨大而复杂的神经网络,他是产生脑电活动的物质基础。脑电活动是神经元动作电位的时空累积,加之人脑中巨量的神经元及更多数量的神经连接,使得脑电波信号表现出混沌行为。癫是由多种病因引起的,以脑内神经元过度兴奋放电所致的突然、反复、短暂的部分或整个脑功能障碍为特征的慢性神经系统疾病。癫发作时脑电活动发生显著变化,出现性放电,这一非线性系统的各种特征量随之也产生变化。目前,脑电图(electroencephalography,EE…
