我们认为图像分析能对胃粘膜上皮异型增生及癌变作出客观正确的诊断、分级。
Therefore, we suggest that image analysis could be taken as an objective index of quantitative diagnosis and grading of epithelial dysplasia and canceration of gastric mucosa.
目的：探讨多原发性肺癌与支气管上皮异型增生及肺泡上皮不典型腺瘤性增生之间的关系。
Objective: to investigate the correlation of multiple primary lung cancer with bronchial epithelial dysplasia and atypical adenomatous hyperplasia of bronchiolo-alveolar epithelium.
结果：术后病理学诊断显示直肠管状绒毛状腺瘤伴上皮异型增生17例（其中多发性腺瘤1例）；
Results:Postoperative pathology showed that, of the 44 patients, 17 were tubulo-villous adenoma with epithelial displasia, including 1 multiple adenomas;
目的检测胃异型增生上皮及胃腺癌组织中神经内分泌的表达。
Objective To detect the neuroendocrine differentiation in gastric epithelial dysplasia and adenocarcinoma.
胃癌中部分患者并不经历肠上皮化生或异型增生阶段。
Some gastric cancer patients did not undergo intestinal metaplasia or gastric mucosa dysplasia.
结论对胃黏膜异型增生和肠上皮化生等病变患者的胃镜随访有利于提高胃癌(特别是早期胃癌)的检出率。
Conclusion Gastroscopy and follow-up of patients with intestinal metaplasia or gastric mucosa dysplasia help to detect gastric carcinoma, especially early-stage gastric carcinoma.
此时使用p16一定要小心解释，因为异型增生的腺体和输卵管上皮化生的腺体均可p16阳性，尽管AIS比化生者阳性更弥漫。
Please be very careful when you use p16 in this situation, since both dysplastic glands and tubal metaplastic glands will be positive for p16, albeit AIS glands are more diffuse than metaplastic ones.
结果：由慢性浅表性胃炎→胃粘膜肠上皮化生→轻度异型增生→重度异型增生→胃癌，端粒酶阳性率逐渐增高，分别为0 %、42 9%、40 0 %、75 0 %、84 0 %。
Results: The positive rate of telomerase in chronic superficial gastritis, intestinal metaplasia, mild dysplasia, severe dysplasia and gastric cancer was 0%, 42.9%, 40.0% 75.0%, 84.5% respectively.
