０ 引言 宫颈癌是女性生殖系统最常见的恶性肿瘤，死亡率居妇科肿瘤第２位．宫颈癌的发生是一个多因素、多步骤的复杂过程，是多种原癌基因的激活和抑癌基因的失活共同作用的结果［１］．目前，原癌基因和抑癌基因与宫颈癌关系的研究已成为分子生物学研究的热点．应用核酸原?
0 Introduction Cervical cancer is the most common malignant tumor of the female reproductive system, with the second highest incidence of gynecologic cancer. Cervical cancer is a multifactorial and multi-step complex process, which is the result of a combination of multiple oncogene activation and inactivation of tumor suppressor genes [1]. At present, the relationship between proto-oncogene and tumor suppressor gene and cervical cancer has become a hot spot in molecular biology research. Application of nucleic acid?
