上皮瘤的

This is prostatic intraepithelial neoplasia, a precancerous cellular proliferation found in a single acinus or small group of acini.

前列腺上皮内瘤变，可在单个腺泡或小群腺泡中见到的非典型增生。

Results Pulmonary carcinosarcoma and blastoma both were found to be rare malignant tumors, and both epithelial and mesenchymal elements can be seen under the microscopy with different characteristic features.

结果 肺癌肉瘤及肺母细胞瘤均为肺内罕见的恶性肿瘤，镜下均可见上皮及间质两种成分，但又有其不同之处，手术前很难确诊。

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)。

Result:TNF-α was localized in the epitheliun and connective tissue of cholesteatomas studied, particularly on basal and spinous cells and macrophages.

结果：TNF-α定位于胆脂瘤组织的上皮及上皮下结缔组织，较正常外耳道及鼓膜的染色明显增强。

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: Patients were randomised in a 1:1 ratio to undergo screening colonoscopy using either chromoscopic endomicroscopy or chromoscopy alone with targeted biopsies.

比较2组检出在上皮内瘤样病变和结肠癌的诊断阳性率上的差异。研究方法：患者随机按1：1的比例分配到结肠镜组和显微内镜组。

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

二者在胆脂瘤上皮的表达有一定的相关性，P＜0.05；与中耳胆脂瘤听小骨骨质破坏程度之间无明显相关性，P＞0.05。

Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium.

CDK4与P16在中耳胆脂瘤发生中是共同而非单独起作用的，从细胞周期的角度可反映胆脂瘤上皮细胞过度增殖的同时也增强负调控因子来抑制增殖，使凋亡同时加快而达到新的平衡。

Middle ear cholesteatoma is destructive to auditory ossicles and temporal bone, and treatment usually includes surgical removal of all epithelial content in the tympanomastoid cavity.

中耳胆脂瘤在临床上对於听小骨和颞骨具有相当的侵蚀性，而治疗上通常必须以手术清除中耳腔所有的上皮成份。

Sept. 11, 2003 Core needle biopsy helps differentiate phyllodes tumor from fibroadenoma, according to the results of a query of a radiology database published in the September issue of the Archives of Surgery . The authors suggest that this technique can signficantly reduce the need for surgery of fibroepithelial lesions.

Sept。 11， 2003-根据一篇发表於9月号Archives of Surgery的研究结果显示，粗针切片检查有助於自纤维性瘤区分出叶状瘤，作者建议，这种技术也可以明显地减少进行纤维上皮之病灶手术的需要。

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。
