上皮瘤的

It was the first time that using 〓 cell line and normal immunity inbreed line BalB/c mice as objects to construct the subcutaneous transplanting ovarian cancer model. Histopathological experiment proved that the transplanting tumor was undifferentiated cancer. The ovarian tumor marker 〓 and the epithelial tumor marker 〓 were positive in the transplanting tumors. According to these proofs we thought we had already succeeded in constructing animal tumor model.

本实验首次采用卵巢癌〓细胞系，以正常免疫力的雌性近交系BalB/c小鼠为对象，建立了卵巢癌皮下移植瘤模型，经病理组织学检查证实移植瘤为低分化癌，经免疫组化检测证实移植瘤组织中卵巢肿瘤标志物〓和上皮性肿瘤标志物〓表达阳性，据此我们认为动物肿瘤模型建立成功。

Result of HE and special dye1.1 result of HE More cells are found in subsequent cholesteatoma. Cholesterol crystal, both sequestrum and neogenesis bone , gland metaplasia, Polykaryocyte are found in subepidermis of subsequent cholesteatoma.

结果1、HE染色结果：可见后天性胆脂瘤上皮的细胞层次增多，上皮内及上皮下有不同程度的急性、慢性炎细胞浸涧；上皮下有时可见胆固醇肉芽肿、死骨与新骨形成、腺体化生等病理改变。

Methods: Specimens of 46 cases of cervical cancer, 12 cases of normal cervical epithelia and 22 cases of cervical intraepithelial neoplasia were examined for E-cad expression by immunohistochemical staining.

应用SP免疫组化法观察12例正常宫颈上皮、46例宫颈鳞癌和22例宫颈上皮内瘤样病变组织中E-cad的表达。

This epithelioid neoplasm looks like a meningioma, although no good meningothelial whorls are displayed.

这个上皮样肿瘤像脑膜瘤，尽管没有形成明显的脑膜上皮旋涡。

Correlations between the indexes and relationship between indexes and the degree of ossicular destruction were investigated.

HIF-1α在胆脂瘤上皮的表达定位于上皮全层，阳性率82.9%，明显高于正常对照组P0.05。

HPV infection can arouse the cleavage and proliferation of cholesteatoma epithelium and may play certain role in the occurrence and development of middle ear cholesteatoma. Aggressive, papillomatous growth and koilocytes can be served as the initial proof of HPV infection in cholesteatoma of the middle ear.

HPV感染可能激发中耳胆脂瘤上皮的分裂增殖，在中耳胆脂瘤发生发展中起一定的作用；侵蚀性乳头瘤样生长和空晕细胞改变可以作为中耳胆脂瘤组织中HPV感染的病理学证据。

Methods The Fas, FasL and DR4, DR5, TRAIL were assessed in 45 normal cervices, 52 cervical intraepithelial neoplasia gradeⅢ and 51 cervical cancers by immunohistochemical method. The number of apoptotic cells was determined by morphological criteria and the number of proliferating cells by counting Ki-67-positive cells. Results Proliferation and apoptosis percentage was markedly increased with increasing severity of neoplasia.

应用免疫组织化学法检测45例正常宫颈组织、52例宫颈上皮内瘤变Ⅲ级(cervical interaepithelial neoplasia Ⅲ， CINⅢ)和51例宫颈鳞状上皮细胞癌组织中Fas、FasL、DR4、DR5、TRAIL的表达，并以显微镜定位表达位置，以Ki-67阳性细胞记数增生细胞数。

At the end of 8 weeks, subcutaneous teratoma was detected in two nude mice, including 3 layers of tissues: sebaceous gland, fat, glandular organ, glandular epithelium and squamous epithelium. At day 4, embryoid body was found and cells were positive for actin, nestin and keratin.

接种8周末，2只小鼠均形成皮下畸胎瘤，其内存在囊括3个胚层的组织结构，包括皮脂腺、脂肪、腺体及腺上皮、鳞状上皮等。

At the same time, the correlation between the expressions of the two indexes and the erosion of ossicles was observed.

结果：MMP-2和CD147在胆脂瘤上皮中表达的阳性率分别为87.3%和84.5%，均显著高于正常外耳道上皮P＜0.05）。

Middle ear cholesteatoma is destructive to auditory ossicles and temporal bone, and treatment usually requires surgical removal of all epithelial content.

中耳胆脂瘤在临床上对於中耳裂具有相当的破坏性，而治疗上通常必须藉手术清除中耳腔所有的胆脂瘤上皮成分。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
