晕可宁颗粒对急、慢性梅尼埃病模型的影响

目的　探讨晕可宁颗粒的主要药效学 ,为临床提供药效学资料及治疗学基础。方法　采用三氯甲烷破坏豚鼠一侧膜迷路感受器模型 ,探讨受试药对眼震颤、摆头及旋转的影响 ;采用内淋巴囊和内淋巴管阻塞手术复制豚鼠膜迷路实验性膜迷路积水模型 ,研究内耳组织平均中阶面积 (SMA)增加率及形态学的变化。结果　抑眩宁阳性对照组、晕可宁颗粒 (8、16g/kg)模型给药组豚鼠眼球震颤次数减少 ,差异有显著意义 (P <0 .0 5 )。成功复制了不同程度膜迷路积水豚鼠模型 ,表现为前庭膜重度膨出 ,前庭阶缩小 ,膜蜗管增大 ,SMA增加率变大 ,差异有显著意义 (P <0 .0 1) ;晕可宁颗粒灌胃后可减轻豚鼠实验性膜迷路积水的程度 ,差异有显著意义 (P <0 .0 1) ;但与空白对照组比较SMA增加率差异无显著意义 (P >0 .0 5 )。结论　晕可宁颗粒可以减轻内淋巴囊积水程度 ,对梅尼埃病症状有对抗治疗作用。     

À propos de la folie à l’opéra

The author evokes the importance of the themes of insanity in opera works, since the l6th century up to the present time. Among those problems: what about the “lyrical delight” provoked by such madness scenes? What is the importance of those operatic arias, in particular since the romantic era? Is there a peculiar, specific, function of the women’s voices in relation to such symptoms?     

维布妥昔单抗治疗Sézary综合征一例

患者,男,41岁。全身弥漫性红斑伴严重瘙痒1年,多发淋巴结肿大3个月。PET/CT符合淋巴瘤;淋巴结病理：非霍奇金T细胞淋巴瘤,伴不规则、扭曲、脑回样核;皮肤病理：非霍奇金T细胞淋巴瘤,呈蕈样肉芽肿改变。结合患者症状、体征、影像学、病理及免疫组化结果,以及外周血T细胞基因重排均为阳性,诊断为Sézary综合征。给予化疗等一线药物治疗效果不佳。更换为含有维布妥昔单抗的治疗方案后患者红斑消退,瘙痒消失,淋巴结减小,达到完全缓解。     

Morel-Lavallée损伤诊疗进展

Morel-Lavallée(MLL)损伤是由剪切力等暴力使皮肤、皮下组织与深筋膜分离而引起的复杂的软组织闭合性撕脱损伤,疾病初期具有复杂性和隐蔽性,常因延迟诊断而导致感染、截肢、多器官衰竭甚至死亡等.目前,MLL的治疗尚无统一指南,需根据损伤情况及患者意愿综合考虑.在合并开放伤、骨折、神经血管肌腱损伤时,处理的优先顺...     

Occurrence, productivity and spatial distribution of key-premises in two dengue-endemic areas of Rio de Janeiro and their role in adult Aedes aegypti spatial infestation pattern

Objectives To evaluate: (1) the occurrence, maintenance, productivity, spatial distribution and premise condition index score of Adese aegypti‐infested houses and key‐premises in a suburban district (Tubiacanga) and a slum (Favela do Amorim) of Rio de Janeiro and (2) the role of these factors in adult Ae. aegypti female spatial distribution. Methods and Results A total of 2456 premises were inspected for immature and 1100 for adult collection. Key‐premises corresponded to 16.08% and 17.86% of infested houses in Tubiacanga, and 13.5% and 11.1% in Favela do Amorim, during the dry and wet seasons, respectively. Key‐premises held significantly more immature Ae. aegypti, pupae and larvae than infested houses in Favela do Amorim and Tubiacanga during the dry and wet seasons. In Favela do Amorim, key‐premises had a significantly higher PCI score than infested but non‐key houses. Conclusion The spatial distribution of key‐premises and adult Ae. aegypti females was often congruent, indicating that key‐premises influence the infestation pattern observed in the study areas.
