本成果采用现代医学、生物学的先进技术,对鼻咽部的癌前病变,即不典型增生的一些生物学特征进行研究。结果证明,鼻咽部不典型增生上皮细胞,特别是底层重度不典型增生细胞的DNA含量、异倍体率、核仁组织者区的数目、大小、形态和“肿瘤性血管生成”等检出数值均在正常组织与癌之间。上述方法可提示不典 This study uses advanced techniques in modern medicine and biology to study some of the biological features of precancerous lesions of the nasopharynx, namely atypical hyperplasia. The results demonstrated that DNA content, heteroploidy rate, number, size, morphology, and “neoplastic angiogenesis” of nasopharyngeal atypical hyperplasia epithelial cells, in particular underlying severe dysplasia cells, were detected. The values ​​are between normal tissues and cancer. The above method can hint at SARS
