脑膜瘤是成人常见的颅内良性肿瘤,占颅内原发肿瘤的14.3%-19%,钙化脑膜瘤少见,骨化脑膜瘤更为罕见,约占脑膜瘤的1%.骨化脑膜瘤是脑膜瘤间叶细胞分化的罕见的一个亚型.根据WHO 分类,骨化脑膜瘤被认为是化生型脑膜瘤,但它的组织学来源目前还不清楚.骨组织不常见于中枢神经系统肿瘤里;可存在于脉络膜瘤,胶质瘤,和垂体瘤中.本文报道1例蝶骨嵴骨化脑膜瘤并文献复习.
Study design A case report of mature teratoma with split cord malformation(SCM)and butterfly vertebrae in a female adult.
Background Schwannomas of Pterygopalatine Fossa are mostly arise from trigeminal nerve.Several approaches can access to this region but their limitations are also obviously.We present a series of 21 c
目的 神经肿瘤的发病及分布情况现在大多引用美国神经肿瘤"红皮书"报告,这是一个以北美洲人群为基础的流行病学报告.不同肿瘤在不同人种中的发生情况应该是不一样的.以中国人群为研究对象的大样本神经肿瘤调查报告将促进对神经肿瘤分布特点的认识,也有利于世界对中国神经肿瘤发病现状的了解.
目的 通过对比胶质瘤手术中应用术中磁共振辅助切除肿瘤患者与常规术者经验切除肿瘤患者的肿瘤切除率、术后神经功能缺失情况及术后出现感染情况,分析移动磁体超高场强术中磁共振在胶质瘤手术治疗的可靠性.
Background Ambiguity in malignant transformation of glioma has made prognostic diagnosis very challenging.Tumor malignant transformation is closely correlated with specific alterations of the metaboli
iRhom1 and iRhom2 are inactive homologues of rhomboid intramembrane serine proteases lacking essential catalytic residues,which are necessary for the maturation of TNFα-converting enzyme (TACE).
Purpose Several recent researches imply that Swiprosin-1 which exhibits actin-binding activity must play an important role in cell movement.We want to know whether Swiprosin-1 is relative with metasta
侵袭和转移是胃癌的重要生物学特征,也是胃癌患者预后不佳的主要原因,但其机制至今仍不十分清楚.肿瘤干细胞被认为是侵袭转移的"种子"细胞.我们前期分离鉴定出胃癌干细胞,发现其具有高侵袭转移特性并呈上皮-间质转化(EMT)表型.
目的:探讨小干扰RNA(small interfering RNA,siRNA)介导的人乳头瘤病毒16 型(HPV16)E6/E7 基因沉默对宫颈癌SiHa 细胞增殖及凋亡的影响.方法:设计靶向HPV16 E6/E7 基因启动子区的siRNA 序列,构建质粒转染SiHa 细胞,筛选稳定沉默E6/E7 基因的细胞系.
