新疆出血热病毒与流行性出血热病毒的生物学特性比较

本文通过免疫荧光(IF)和电镜(EM)技术对新疆出血热(XHF)及流行性出血热(EHF)病毒的生物学特性在Vero E_6及LLC-MK_2两株传代细胞上进行了比较。两种病毒感染两株细胞后免疫荧光染色有两种不同的荧光形态特征,两种病毒对细胞的敏感性明显不同,XHF病毒在LLC-MK_2细胞上感染后6～8天可出现明显的细胞病变,而EHF病毒感染此细胞后则不引起病变。电镜观察到两种病毒在LLC-MK_2细胞中都能形成与布尼病毒相似的形态特征。     

Post-ictal fever: a rare symptom of partial seizures

Although fever may induce seizures, especially in children, its occurrence following epileptic spells has been rarely described, except from generalized convulsive status epilepticus. We present two patients suffering from focal seizures accompanied by episodes of post-ictal fever, and review similar reports in the literature of the last 40 years. Temperature changes following non-convulsive seizures might be induced by gene upregulation occurring in the hypothalamus, the nucleus tractus solitarius, or in other brain regions, producing a local inflammatory response. Direct propagation of electrical discharges seems less consistent with the timing of development of this symptom. Heterogeneity of reported clinical features argues against the assumption of a definite localizing or lateralizing value for post-ictal fever.     

血清补体系统在流行性出血热患者中的变化及其意义

应用单向免疫扩散法测定了流行性出血热(EHF)患者的7种补体成份和血浆素原(Pg).结果表明,CT脂酶抑制剂在少尿期、多尿期和恢复期均高于正常(P<0.01);补体C_1q在多尿期高于正常(P<0.01);补体C_4在发热期和少尿期低于正常(P<0.01),以后逐渐恢复正常;补体C_3,C_5和C_9的变化与C_4相似;B因子在少尿期低于正常(P<0.01),在多尿期高于正常(P<0.05);Pg始终高于正常水平但在少尿期有回降.说明EHF患者不仅有补体经典途径的识别阶段、活化阶段和膜攻击阶段的变化,而且亦有旁路激活,其活化程度与病情有关.

Stephen Girard (1750–1831): a one-eyed American patriot

Stephen Girard trader, banker, millionaire, and patriot lived 81 full and exciting years. Apparently born with a blind or amblyopic right eye, he emigrated from Bordeaux. France, via Santa Domingo to the United States, and finally settled in Philadelphia, where he developed a successful maritime trade. Ultimately, Girard became the first multimillionaire in the United States. Extremely generous, he often walked from his home in the center of Philadelphia to his farm in what is now South Philadelphia distributing shoes to needy children. Probably Girard’s most heroic gestures were his gallant fight against the yellow fever epidemic in 1793 and his loan to the U.S. government during the War of 1812, which allowed the bankrupt country to continue the conflict and ultimately to win the war. Presented, in part, at the tenth annual meeting of the David G. Cogan Ophthalmic History Society, the College of Physicians of Philadelphia, March 8 and 9, 1997.     

发热门诊的感染控制

笔者介绍了我院发热门诊的特点以及特殊规定，为加强控制感染，我院要求对发热门诊人员进行培训、体检，实行军地患者分开诊治，重视消毒隔离工作，发热门诊人员集中居住，无关人员禁入发热门诊，制订了严格的规章制度及就诊流程图。经过严格的控制，我院发热门诊运转正常，发热门诊无交叉感染出现。     

实验动物大白鼠型流行性出血热流行病学和临床症状调查

本文对59名接触实验动物大白鼠引起23例流行性出血热(EHF)的流行病学和临床症状进行了调查,发病率为38.98%。发病的有副教授、讲师、助教、研究生等。发病多在春季,年龄组在21～40岁,男多于女。经间接免疫荧光技术检查,大白鼠肺EHFV抗原阳性率为32.69%。临床分型以中型为多,其次为重型和轻型。临床症状以发热、头痛、腰痛、全身痛、食欲不振、酒醉貌为主,没有死亡病例。血清间接免疫荧光抗体IgG在1:320～1:5 120之间的占91.30%。     

SARS临床特点分析

目的 :探讨SARS的临床特点、诊治方法。方法 :对 2 0 0 3年 3月至 2 0 0 3年 5月收治的 2 9例传染性非典型肺炎患者进行回顾性分析 ,总结其流行病学特点、临床表现、血常规及影像学检查特点。结果 :本组 2 9例全部以发热为首发症状 ,有明确接触史者 2 5例 (占 86 .2 % ) ,第一次血常规白细胞降低者有 8例 (占 2 7.6 % ) ,淋巴细胞计数 <0 .9× 10 9 L者 19例 (占 6 5 .5 % ) ,白细胞计数出现进行性下降者 2 2例 (占 75 .9% )。所有患者胸片显示肺部阴影 ,其中迅速进展者 18例 (占 6 2 .1% )。治疗采用抗病毒、抗感染、支持等综合治疗 ,重症患者使用大剂量甲泼尼龙和无创机械通气。结论 :流行病学史、临床特点是早期诊断的关键 ,治疗采取综合方法 ,对重症患者使用大剂量激素、无创机械通气治疗有效     

103例流行性出血热患者的心电图及心肌酶学分析

目的了解流行性出血热病毒(EHFV)对心脏的损害情况。方法对103例流行性出血热(EHF)患者的心电图及心肌酶学检测结果进行分析。结果72例(69.9%)患者出现心电图异常,以窦性心动过缓(27.9%)及窦性心动过速(22.3%)最常见,明显高于其它类型的心电图改变(P分别<0.05和0.001)。103例流行性出血热(EHF)患者的CK、LDH及HBDH的升高者分别为43例(41.2%)、73例(70.9%)及46例(44.7%),以LDH异常最常见。轻型、中型、重型及危重型流行性出血热患者的LDH值分别为(346.3±155.6)IU/L、(330.7±130.7)IU/L、(1114.4±872.4)IU/L及(1227.1±936.7)IU/L,经统计学处理重型及危重型的值与轻型、中型比较均有显著性或高度显者性差异。结论EHF患者并发心肌损害较普遍,而且病情愈重者,心肌损害愈严重。
