生癌的

We report a case of high grade large cell neuroendocrine carcinoma concomitant with tubulovillous adenoma of the ampulla of Vater.

本文报告一个壶腹部高级大细胞型神经内分泌癌并生绒毛管状腺瘤的病例。

Intestinal metaplasia of the gastric mucosa was regarded as theprecancerosis of gastric cancer.

胃黏膜肠上皮化生是胃癌的癌前病变，与肠型胃癌密切相关。

Background and aim : Gastric intestinal metaplasia is generally considered to be a precancerous lesion in the gastric carcinogenesis cascade.

背景目的：胃的肠化生公认为是胃癌发生的癌前病变。

Objective The development and progression of intestinal metaplasia and expression of tumor － related proteins in dog ' s stomach were observed.

目的系统观察胃粘膜肠化生的形成及其发展趋势以及病变过程中癌相关基因蛋白表达。

The mucinous cells are likely to be metaplastic and a result of aberrant differentiation in a premalignant squamous lesion.

这些黏液细胞很可能化生而来，也可能是癌前鳞状细胞病变异常分化的结果。

Currently we call metaplastic ca if the cases have classic of metaplasic components, such as spindle cells, squamous cells, chondro-osseous.

一般，如果病例中有典型的化生成分，如：梭形细胞，鳞状细胞、软骨，我们则称之为化生性癌。

AIM: To investigate the correlation of phosphatase and tensin homolog deleted on chromosome ten protein expression and clinicopathological features in the precancerous lesions and early gastric cancer, and to explore its clinical implication in early development of gastric cancer.

目的：观察正常胃黏膜、肠上皮化生、异型增生和早期胃癌中抑癌基因PTEN的蛋白表达，探讨PTEN表达在胃癌早期发生过程中的作用。

In gastric ulcerocancer, the main radiological changes of the interface are small teniform non-plicae area, the slim irregular plicae near the ulcer connecting with distal clubbed plicae. The juxta-ulcer presentation are instinct mucosal plicae, especially blurred teniform plicae and reticular plicae accompanying with "target sign" in most cases and the pathologic changes of peri-ulcer are chronic atrophic gastritis, intestinal epithelial metaplsia and epithelial heterotypic hyperplasia of gastric mucosal etc.

溃疡型胃癌溃疡病灶与周围交界面主要X线表现为小带状无皱襞区，近溃疡侧的纤细不规则皱襞与远侧的杵状皱襞相接；溃疡旁X线表现是粘膜皱襞影像多较模糊，尤以模糊条纹状皱襞及模糊网格状伴有&靶征&居多，病理镜下改变是以慢性萎缩性胃炎、肠上皮化生及胃粘膜上皮异型增生等癌前病变为主。

Methods cag model of rats was made by composite methods .the rats were randomly divied into normal control group, model group and treatment group.

已有大量研究表明本病与胃癌的发生有密切关系，尤其伴有肠上皮化生或不典型增生时有癌变的可能，被认为是胃癌癌前病变之一。

More serious problems with smoking and dental hygiene may include gum disease and oral cancer.

更严重的问题与吸烟及牙科生可能包括牙龈疾病和口腔癌。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
