上皮瘤

Cancer of ovarian and transparent cell is most constant tumour of as epithelial as the ovarian surface of confuse of interblend of tumour of cell of the former reproduction that send a gender sex, especially with yolk bursa tumour and asexuality cell tumour are differentiated harder.

梗概： 卵巢透明细胞癌是最常和原发性生殖细胞肿瘤相混淆的卵巢表面上皮性肿瘤，尤其和卵黄囊瘤和无性细胞瘤较难鉴别。

Objective To study the relationship among different types of human papilloma virus, cervical intraepithelial neoplasia and cervical carcinoma.

目的 探讨不同类型人乳头瘤病毒与宫颈上皮内瘤变和宫颈癌的关系。

Methods:The model was established by transplanting the subcutaneous tumor into omentum of nude mice.

将人上皮性卵巢癌细胞株Hey细胞种植于裸鼠皮下成瘤后半包埋缝于裸鼠脾区网膜建立网膜移植瘤模型。

A core needle biopsy misdiagnosed PASH in 13 cases out of 28 cases and vacuum-assisted biopsy correctly identified PASH in all 3 cases.

4细胞性纤维腺瘤和囊肉瘤：PASH缺乏真正的间叶细胞过生长的现象，其细胞缺乏多形性，无核分裂象，也没有纤维腺瘤或囊肉瘤的上皮成分的生长类型。

In other areas, sheets of epithelioid cells with prominent nuclear pleomorphism were seen; scattered tumor giant cells and multinucleated tumor cells were also present (Figure 1, B ).

在其他区域，可以见到成片的具有明显多型现象的上皮样细胞；散在的瘤巨细胞和多核瘤细胞也可以见到(图1B)。

Results With the expression in normal salivary gland as a standard, low C-erbB-2 mRNA expression was seen in adenolymphoma, basal cell adenoma. However, various degrees of over-expression of C-erbB-2 oncogene mRNA were detected in pleomorphic adenoma, mucoepidermoid carcinoma,acinic cell carcinoma ,adenoid cystic carcinoma ,papillary cystic carcinoma,and myoethelial cell carcinoma.

结果 正常涎腺和涎腺肿瘤中发现不同程度C-erbB-2mRNA的表达，以正常涎腺组织的表达水平为基准，在腺淋巴瘤、基底细胞腺瘤呈现低表达、无表达或与正常涎腺组织表达水平相似，多形性腺瘤、粘液表皮样癌、腺泡细胞癌、腺样囊性癌、乳头状囊腺癌和肌上皮癌则呈现不同程度的过表达。

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。

Resut: the results of 21 cases of stomach malignant stromal tumors immunohistochemical were positive.the great mass of ck and ema were negative.among the 21 cases,3 patients of extensive metastasis were dead after operation,2 patients were given polypectomy,but they recured after operation 8 months and 9 months.one of them was operated again and lived 1 year,16 patients were disease-free survival 3 to 6 years.

结果：21例免疫组化结果示cd34均为阳性，而上皮指标细胞角蛋白和膜上皮抗体大部分阴性；其中3例广泛转移者于术后4～6月死亡，姑息性切除2例，术后8月及9月均复发，其中1例再次手术，存活1年，其余16例均无瘤生存，生存期为3至6年。

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）。

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。
