[Method] Antigen location and histopathological observation in natural cases infected by highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) were analyzed by immunohistochemistry and H. E. staining. [Result] The virus antigen mainly existed in epithelial calls, and also a few in mecrophages, lymphocytes and brain nerve cells. [ Conclusion] The cell and tissue tropism of HP-PRRSV strain in natural cases is different from that of previous strains.展开更多
目的探讨卒中后病理性哭笑(poststroke pathological laughing and crying,PSPLC)的病灶分布模式并分析其可能机制。方法选取2012年5月至2015年12月间于本院神经内科住院的急性脑梗死患者并随访至卒中后6个月所筛查出的病理性哭笑(...目的探讨卒中后病理性哭笑(poststroke pathological laughing and crying,PSPLC)的病灶分布模式并分析其可能机制。方法选取2012年5月至2015年12月间于本院神经内科住院的急性脑梗死患者并随访至卒中后6个月所筛查出的病理性哭笑(PLC)患者24例为研究对象,回顾性分析其MRI病变部位分布;选取同期性别、年龄相匹配的不伴PLC的孤立性脑桥梗死患者28例与脑桥梗死合并PLC患者14例比较,了解其脑桥病变的侧别差异。结果24例PSPLC患者中,PLC在卒中后第二个月出现最多,占41.67%;强哭15例(62.5%)、强笑3例(12.5%)、强哭强笑6例(25.0%)。24例PSPLC患者中,头颅MRI显示左侧病变3例,右侧病变1例,双侧病变20例,基底节病变9例,丘脑病变8例,辐射冠病变6例,半卵圆中心病变5例,皮层病变4例,小脑病变4例,脑桥病变14例;脑桥病变合并PLC的14例患者中,孤立性脑桥梗死1例,合并其他部位梗死13例。不伴PLC的孤立性脑桥梗死患者单侧脑桥病变出现比率(71%)高于脑桥梗死合并PLC患者(50%),差异无统计学意义(Х^2=0.844,P=0.358)。结论PSPLC是卒中后并非罕见的并发症,其发病与多部位受累有关,其中桥脑梗死出现的比率高。展开更多
