浆细胞瘤

This high power microscopic appearance of cardiac myxoma shows minimal cellularity. Only scattered spindle cells with scant pink cytoplasm are present in a loose myxoid stroma.

高倍镜可见心房粘液瘤极小的细胞结构，仅有散在的纺锤形细胞，在疏松的粘液样基质中有少量淡红的胞浆存在。

Most endothelial cells fell off, elastic fibre autolyze; the number of SMC decreased, some SMC nucleus contracted completely or depressed, typical apoptosis body were seen in later stage, muscle silk autolyzed and disappeared mostly; in outer layer saw much collagenic fiber, arranged unorderly; inflammation cells were seen in the aneurysm wall(hypertrophy cell et al.).

多数瘤壁的内皮细胞溶解脱落，不连续，弹力纤维自溶；动脉瘤血管壁均可见SMC明显减少，较多SMC染色质边聚、固缩，部分SMC核全部固缩或出现不规则凹陷，SMC核胞浆或胞核部分出现脱落或裂解成碎片，晚期可见典型的凋亡小体出现，肌丝大都自溶消失：外膜可见大量的胶原纤维，排列较紊乱；瘤壁还可见炎性细胞浸润。

Tumor cells change: As the cytoplasm of the increase in core protein precursor mostly basophilic.

瘤细胞胞浆的改变：由于胞浆内核蛋白体增多而多呈嗜碱性。

Results The lesion appeared to originate in the right atrium and involved the venae cavae and the left atrium.

结果肿物位于右心房并向上下腔静脉延伸、部分与左心房壁相连，镜下为弥漫性增生的异型淋巴细胞，瘤细胞胞体大，胞浆丰富，间有瘤巨细胞。

Results Lactacystin dealed with C6 glioma cells in 24 h, kytoplasm was concentrated and anachomasised, the chromatin of nucleus was concentrated pyknoticly to see under photo-microscope. The microvilli on surface dispeared、nucleus crenated、chromatin aggregated pyknoticly under transmission electron microscope respectively.

结果 Lactacystin处理体外C6胶质瘤细胞24 h后，光镜下见胞浆浓缩深染，胞核染色质致密浓缩，透射电镜下见细胞表面微绒毛消失，核皱缩，染色质致密浓缩、边集。

Results Microscopically, AM was characterized by hypercellularity, high karyoplasma ratio, prominent macronucleoli, strange heterokaryocyte and tiny focal necrosis. Of 11 cases, recurrence was noted in three, and one transformed into anaplastic meningioma and died 1 year after reoperation.

结果 AM光镜下瘤细胞密度增大，核浆比例增高，核仁明显，多伴有奇异核细胞出现和微小坏死灶。11例AM病人中，3例复发，1例复发后转变为间变性脑膜瘤，再次手术后1年死亡。

Tumor mass could express CD133 and nestin. The karyoplasmic ratio of CD133+ brain glioma stem cells reached 2/3-3/4, and there were a few processes, a few organelles and a plenty of ribosome. These were accorded with the characteristics of stem cells.

肿瘤球能同时表达干细胞标志物CD133和巢蛋白，CD133+脑胶质瘤干细胞核浆比例达2/3~3/4，突起少，胞浆中线粒体等细胞器较少，核糖体丰富，未见胶质丝等分化结构，符合干细胞超微结构特点。

A strain of breast tumor cell line ZHL2006 was established and biologically identified. The ZHL2006 cells grew fast in vitro and the population doubling time was 43.6h. Electronmicroscopical observation showed that there were microvilli on the surface of the cells, nucleus irregularity, karyoplasmic ratio increased, nucleolus distinctness, et al.. Chromosome number and structure were abnormal. Immunohistochemistry showed that PCK were expressed. The ZHL2006 cell line could form onto clone in soft agar and had oncogenicity in athymic mice.

ZHL2006细胞在体外生长迅速，群体倍增时间为43.6h；倒置相差显微镜及Giemsa染色镜下观察细胞为多边形及梭形；透射电镜观察可见细胞表面有微绒毛，核高度不规则，核浆比例增大，核仁明显等；染色体数目和结构异常；广谱细胞角蛋白染色阳性，说明其自上皮而非来自基质；同时ZHL2006细胞系在软琼脂中可形成克隆，具裸鼠致瘤性。

Results The BMC surrounding tumor mass and strands showed multi-layered or dissolution, pseudopodia were seen extended from tumor cells, and contained numerous microvesicles.

瘤细胞伸出伪足样突起，且胞浆内含大量微泡，该处基膜消失，胶原原纤维溶解，肿瘤细胞围绕血管部位的血管基膜增厚，纤维组织增生。

The tumor cells are large in size, very pleomorphic, and have abundant, vacuolated to dense cytoplasm, and hyperpchromatic nuclei with irregular contours and prominent nucleoli.

瘤细胞个大，多形性明显，浆丰，胞浆从空泡状到致密，核深染，外形不规则，核仁明显。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
