The relationship of intraepithelial blood vessels and NBI system in oral borderline malignancies.

应用免疫组织化学方法检测口腔交界性恶性肿瘤上皮异型增生和原位癌组织中CD31和IV型胶原的表达。在独联体国家，感染性乙型肝炎病毒的数量显著增加。结果表明，窄带成像（NBI），这是建立可视化异常微血管模式是一个有效的工具，口腔交界性恶性肿瘤的鉴别诊断和决定一个足够的安全边界。

Blood capillary vessels within the epithelial zone(IEBVs) of oral borderline malignancies including epithelial dysplasia and carcinoma in-situ(CIS) were examined by immunohistochemistry for CD31 and type IV collagen. IEBVs increased in number significantly in CIS. It was revealed that narrow band imaging(NBI), that is established to visualize abnormal microvascular patterns was a effective tool for differential diagnosis of oral borderline malignancies and decision of a adequate safety margin.
