上皮瘤

Objective:To compare the DNA character with in cholesteatoma tissues with that in normal skin.

目的：采用流式细胞术分析胆脂瘤上皮细胞的DNA特征，探讨胆脂瘤的病理学属性。

Recent reports have shown that the inhibition of cholesteatoma epithelial cell apoptosis plays an important role in the formation and development of cholesteatoma.

最新研究表明胆脂瘤上皮细胞凋亡受到抑制在中耳胆脂瘤的发生和发展中起着重要作用。

Objective To investigate the diagnostic value of thinprep cytologic test and electronic colposcope examination in patients with subclinical human papillomavirus infection and cervical intraepithelial neoplasia, and explore its concordance with pathologic diagnosis.

目的 探讨新柏氏膜式液基细胞学检测和电子阴道镜检查对宫颈人乳头瘤病毒亚临床感染和宫颈上皮内瘤变的诊断价值及其与病理诊断的一致性。

Human epidermoid carcinoma A431 xenograft in nude mice was used to investigate inhibitory effects of the fusion protein in vivo.

体内抑瘤实验表明融合蛋白能够显著抑制人鳞状上皮癌A431裸鼠移植瘤的生长，且毒副作用较小。

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。

Results The total tumors and cranial bone around them were removed in 4 patients with intraosseous meningiomas.

病理检查显示，4例颅骨内脑膜瘤中，砂粒型2例，脑膜上皮型和恶性脑膜瘤各1例。

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。

In this particular case, there were osteomas of the skull, a periampullary adenocarcinoma , and epidermal inclusion cysts.

这例病例较为特殊的是有颅骨骨瘤，近壶腹部的腺瘤，表面有一个上皮覆盖的囊腔。

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.
