目的 探讨围绝经期妇女出现不规则阴道流血的诊断思路及要点,提高对疾病的认识,减少误诊.方法 对在武汉大学人民医院生殖科就诊的围绝经期妇女粘膜下子宫肌瘤合并异位妊娠出现不规则阴道流血的一例病历进行回顾性分析.
Regulation of B cell apoptosis in the germinal center (GC) is critical for normal immune responses.We found that the ELL-associated factor 2 (EAF2) was selectively upregulated in GC B cells and that i
目的:核辐射所释放的放射性物质主要是131I,在接受了原子弹爆炸或者是核泄漏所释放的131I照射的人群中,甲状腺癌的发生率明显升高,特别是0-4岁的儿童甲状腺癌的发生率最高.肿瘤的发生与机体免疫系统功能紊乱密切相关,本研究以幼龄小鼠为研究对象,探究模拟核辐射—不同剂量的131I对幼龄鼠免疫系统发育的影响.
Background: More recently, mast cells have been depicted in their potential to boost mucosal vaccination as mast cell activators are demonstrated to be powerful mucosal adjuvants.There are two phenoty
Background: Discovery of F protein expressed from the HCV core coding sequence challenges properties assigned to core protein, however, little is known about its correlation between evolution of HCV s
Most cell types have the capability to sense and respond to the physiological fluid flow-derived shear stress (SS).Dendritic cells (DCs) are the most powerful professional antigen-presenting cells as
Background : The naturally acquired human immunity to malaria is in some way defective or short-lived.Objective: We have investigated the kinetics, duration and characteristics of the Plasmodium-speci
细菌等病原体侵人体内后,可以被巨噬细胞吞噬消灭,也可以经巨噬细胞抗原提呈后启动适应性免疫应答.在巨噬细胞对病原体的免疫应答过程中巨噬细胞可以向不同的方向极化.在急性感染性疾病中,巨噬细胞以M1型极化为主,M1型巨噬细胞主要作用是促进炎症和杀灭细菌的作用;在慢性感染性疾病中,巨噬细胞以M2型极化为主,M2型巨噬细胞的主要作用是调节炎症.巨噬细胞的极化可以影响感染性疾病的发展,病原体也可以影响巨噬细胞
Background: Homotypic cell aggregation plays important roles in physiological and pathological processes, including embryogenesis, immune responses, angiogenesis, tumor cell invasion and metastasis.CD
In order to obtain a certain length(630bp) of constant domain gene, a pair of primer was designed according to the conserved nucleotide sequence of gallus(EU477527.1) and Taeniopygia guttata (XM_00218
