内皮瘤

ABSTRACT Purpose To study the diagnosis and differential diagnosis of epithelioid hemangiendothelioma of brain.

目的：探讨脑上皮样血管内皮瘤的诊断及鉴别诊断。

Epithelioid hemangioendotheliomas are intermediate grade vascular malignancies that are closely associated with or arise from a vein in 50% of cases.

上皮样血管内皮瘤是中度恶性的血管肿瘤，50%的病例与血管密切相关或起源于血管。

objectivs To study clinicopathologic characteristics and differential diagnosis of epithelioid hema-ngioendothelioma of the uterus.

目的 探讨子宫上皮样血管内皮瘤的临床病理学特征和鉴别诊断。

Pulmonary epithelioid hemangioendothelioma is a rare disease of borderline malignancy.

肺上皮样血管内皮瘤是一个低恶性度的少见疾病。

Methods Human hemangioma endothelial cells cultured in vitro were injected hypodermically into nude mice(BALB/c nude mice). The volume of in the transplanted tumor was measured in 60 days. Samples were taken from survival tumor and stained immunohistochemically by CD31 and Ki-67 before subjected to histopathological examination.

将体外培养的血管瘤内皮细胞通过注射的方式植入裸鼠(BALB/c nude mice)皮下，测量不同生长时期瘤体体积变化，观察至60天后进行病理学光镜检查，并通过血管内皮细胞单克隆抗体CD31、细胞增殖标记抗体Ki-67免疫组化染色研究所成瘤体的同源性及增殖活性。

MethodsThe transplanted tumor model of the mouse S180 sarcoma was established.Fifty mice were randomly divided into five groups,the control group,the CTX group,the Gecko group.They were treated respectively with oral administration of saline,and intraperitoneal injection of CTX 100 mg/kg only one time,oral administration of Gecko in doses of 13.5,9,4.5 g/kg,one time a day.After 14 days,the anti-tumor activity was evaluated by tumor tissue weighing. The impact on immune organ was detected by accounting thymus index, spleen index and the number of peritoneal macrophage which phagocytose chicken red blood cells.The protein express of vascular endothelin growth factor and basic fibroblast growth factor were detected by SABC immunohistochemistry.

方法建立移植瘤小鼠S180肉瘤模型，将50只雌鼠随机分为对照组、环磷酰胺组、壁虎高组、中组、低组共5组，分别给于生理盐水灌胃1次/d，CTX（100 mg/kg）腹腔注射1次，壁虎高、中、低组（13.5，9，4.5 g/kg），每天灌胃1次。14 d后，称取荷瘤小鼠瘤重、胸腺重、脾脏重，计算抑瘤率、胸腺指数、脾脏指数，观察腹腔巨噬细胞吞噬鸡血红细胞实验指标；用SABC免疫组化法检测血管内皮生长因子、碱性成纤维细胞生长因子的蛋白表达，TUNEL方法检测细胞凋亡率。

By culturing human brain microvascular endothelial cells and glioma cells separatedly and simutaneously ,and then analyzing their pre- and post-cultune FasL levels, we study the effect of the grouth of glioma cells upon FasL level of human brain microvascular endothelial cells.

我们通过将人脑毛细血管内皮细胞与胶质瘤细胞分别培养及共同培养，对培养前后人脑毛细血管内皮细胞与胶质瘤细胞FasL表达水平的分析，来探讨胶质瘤细胞的生长对人脑毛细血管内皮细胞FasL表达的影响。

Kaposiform hemangioendothelioma also has slit-like lumina, although they are due to nodules and sheets of compact spindle cells.

Kaposi型血管内皮瘤也有裂隙样腔隙，尽管它们是由于致密的结节状或成片梭形细胞受挤压所致。

Blood-brain barrier in tumors and peritumoral oedematous regions had the same variations in ultrastructure.

瘤体和瘤周水肿区血脑屏障超微结构变化无明显差异，内皮肿胀，毛细血管腔狭小，胶面有稀疏的绒毛样突起，内皮为无孔型，胞质内胞饮泡较多，内皮紧密连接增长，细胞连接间隙增宽，基膜完整，胶质膜缺损。

Herein we report a case of a 61-year-old man with multiple red-violet plaques over his right palm for more than two years.

我们报告一个61岁男性病人，在其右手掌有多发性紫红色斑块已有二年多，并在他的左心室发现有肿块，因此为他作开心手术及皮肤切片，二处的病理表现均符合上皮样血管内皮瘤。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
