瘤形

Results MRI features of intracranial lymphoma were as follows:(1) Single or multiple lesions,most in supratentorial site.(2) Round or irregular in shape,hypointensity on T1WI and isointensity or hyper-intensity on T2WI,with homogenous signal.(3) Edema around the lesion,with mild space-occupying effect.(4) Markedly enhanced.(5) Disseminated via leptomeninges and/or via ventricular ependyma.(6) Sensitive to chemotherapy and radiotherapy.(7) Changeable in size and shape.

结果 病灶单发或多发，以幕上分布为主；圆形或不规则形，T1WI呈低信号，T2WI呈等或高信号，信号多均匀；瘤周水肿及占位效应多较轻；增强扫描病灶均明显强化；可侵及软脑膜和/或室管膜并沿之播散；对放、化疗敏感；形态、大小可变化。

Results: MRI features of primary malignant lymphoma were as follows:①single or multiple lesions, mostly in supratentorial region;②round or irregular in shape, hypointense on T1WI, hypointense or isointense on T2WI with homogenous signal;③mild edema around the lesion with mild space occupying effect;④remarkable enhancement of the lesion;⑤involvement of leptomeninges and/or dissemination via ventricular ependyma;⑥sensitive to chemotherapy and radiotherapy. Size and shape changed remarkedly after treatment.

Kaposiform hemangioendothelioma is a very infrequent, locally aggressive vascular neoplasm, characterized by fascicular spindle cell proliferation.

卡波西样血管内皮细胞瘤是一种非常罕见的，具局部侵犯性的血管肿瘤，其特徵为束状梭形细胞增生。

The petal of Gli CMS crimples.The stamen turns into featheriness, the form of the petal , silk form or degradates. Without anther structure, the carpel, it is protruding that the outer edge grows tumour form.The growing style of stamen and pistil is the adhesion type or the scattered type. The shape of pistil is straight or hooked. The opening style of flower is full-nfolded,half-closed or full-closed.

Gli CMS的花瓣皱缩，雄蕊变为羽毛状、花瓣状、丝状或者退化；无花药结构，心皮化，周缘生有瘤状突起；雌雄蕊着生方式为粘连型，有的是散生型；雌蕊有的是直柱形，有的是钩型的；花朵开放方式为全展型、半闭型和全闭型。

High-level nuclear β-catenin staining serves as a useful diagnostic tool for desmoid-type fibromatosis. The high expression of ER-β in desmoid-type fibromatosis provides a biological mechanism for the antiestrogenic compounds to treat fibromatosis.

高水平β-catenin核阳性表达可用于辅助韧带样型纤维瘤病诊断以及与其它梭形细胞肿瘤的鉴别诊断。

Results Microscopically, the tumor cells were epithelioid or short spindled and special nests of tumor cells separated by arboring fibrovascular septa. Such morphological variants of CCSK as myxoid degeneration, microcysts formation and sclerosing pattern of extracellular hyalined collagen simulating osteoid were present in some regions.

结果 镜下见瘤细胞为上皮样或短梭形，被分枝状纤维血管间质分隔成巢团状，部分区域见黏液样变性微囊肿和细胞外胶原玻璃样变类似骨样组织的硬化型等形态变异。

Basal or lower stem leaves hastate; rhizomes horizontal; valves shorter than or equaling achenes, without tubercles; pedicel articulate near base of tepals.

基部的或下部茎叶戟形；根状茎水平；裂爿短于或与瘦果等长，没有小瘤；花被片的花梗有节近基部。 1 R 。 acetosella 小酸模

Cases of tumor was performed by immunohistrochemical staining EMA and Vim were positive. 12 cases were hyperplasic lesions of mesothelial cell. Induced rats' MPM had a higher similarity with human' s MPM, especially in pathogenicity, positions, histological type and biological behavior of invasion and metastesis.

结果 实验组发生胸膜间皮瘤66例，诱发率71.74%，大体形态肉眼结节型间皮瘤较多见（72.73%）组织形态可见上皮型、梭形细胞型及混合型双向多潜能分化，13例免疫组化EMA及Vim双向阳性，并可见12例胸膜间皮细胞增生性病变，诱发瘤在病因，发病部位，组织形态学以及浸润转移的生物学行为方面与人体间皮瘤极为相似。

Objective To investigate the significance of the overexpression of PCNA gene in cervical intraepithelial neoplasm and squamous cell carcinoma.

目的 探讨PCNA基因过度表达在子宫颈上皮内瘤变及子宫颈鳞形细胞癌中的意义。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
