吉兰—巴雷综合征与空肠弯曲菌感染

吉兰-巴雷综合征是自身免疫介导的周围神经病,主要的病理改变是周围神经组织小血管淋巴细胞、巨噬细胞浸润,神经纤维脱髓鞘,严重病例可继发轴索损害。吉兰—巴雷综合征的发生是由于易感人群感染病原菌后,机体针对病原菌抗原成分产生相应抗体,该抗体与人体神经节苷脂发生交叉免疫反应;同时在多种细胞因子的协同作用下,影响神经传导功能,最终产生不同程度的髓鞘脱失,严重者可导致轴索变性。空肠弯曲菌是其中最常见的病原菌,本文就吉兰—巴雷综合征与空肠弯曲菌感染的关系予以综述。     

The Old Kinship Studies Confronts Gay Kinship: A Critique of Kath Weston

Kath Weston's highly-acclaimed analysis of gay kinship is examined in the light of the old kinship studies, especially the notion of focality. The verdict is quite contrary to Weston's, viz. that gay kinship and the idea of gay families are structural derivatives of heterosexual kinship and heterosexual families. Weston's work is shown to be part of a larger collectivist project in kinship theory in which key concerns in semantic theory are ignored.
