[摘要] 目的 探讨人乳头状瘤病毒L1壳蛋白和人端粒酶RNA基因联合检测在宫颈癌筛查中的意义。 方法 选取2012年10月~2014年10月新疆医科大学第一附属医院行宫颈癌筛查的患者627例,先行液基细胞学检查,后行阴道镜检查并取活检,同时行人乳头状瘤病毒L1壳蛋白检测和人端粒酶RNA基因检测。分析不同病症间临床指标的变异情况。 结果 未见上皮病变或恶性改变(NILM)、意义不明的不典型鳞状细胞与不典型腺细胞(ASC-US)、不除外高度鳞状上皮内病变的的不典型鳞状细胞(ASC-H)、低度鳞状上皮内病变(LSIL)、高度鳞状上皮内病变(HSIL)、鳞状细胞癌(SCC)、腺癌(AC),人乳头状瘤病毒L1壳蛋白阳性表达率分别为18.6%、42.9%、51.0%、80.6%、47.4%、5.9%、0.0%,差异有高度统计学意义(χ2 = 93.770,P < 0.01),呈先升高后降低趋势,在LSIL达到最高点,在AC降至最低点;人端粒酶RNA基因阳性表达率分别为0.0%、19.9%、36.3%、51.6%、94.7%、100.0%、100.0%,差异有高度统计学意义(χ2 = 279.564,P < 0.01),呈持续升高趋势 ,在SCC与AC达到最高点。依正常、炎症、宫颈上皮内瘤变(CIN)Ⅰ期、CINⅡ期、CINⅢ期、宫颈癌顺序,人乳头状瘤病毒L1壳蛋白阳性表达率分别为18.6%、46.1%、80.6%、53.3%、25.0%、3.6%,差异有高度统计学意义(χ2 = 93.015,P < 0.01),呈先升高后降低趋势,在CINⅠ期达到最高点,在宫颈癌降至最低点;人端粒酶RNA基因阳性表达率分别为0.0%、26.4%、51.6%、93.3%、100.0%、100.0%,差异有高度统计学意义(χ2 = 269.582,P < 0.01),呈持续升高趋势 ,在CINⅢ期达到最高点。 结论 人乳头状瘤病毒L1壳蛋白联合人端粒酶RNA基因检测,在宫颈癌前病变中具有较高的指导价值。

[Abstract] Objective To investigate significance of human papilloma virus L1 protein and human telomerase RNA gene combined detection in cervical cancer screening. Methods From October 2012 to October 2014, in the First Affiliated Hospital of Xinjiang Medical University, 627 patients given cervical cancer screening were selected. Firstly, the patients received liquid based cytology, then they received colposcopy and biopsy, at the same time, they also received human papilloma virus L1 protein detection and human telomerase RNA gene detection. The variation of clinical indicators were analyzed between different conditions. Results According to sequence of NILM, ASC-US, ASC-H, LSIL, HSIL, SCC, AC, positive expression ratio of human papilloma virus L1 protein were 18.6%, 42.9%, 51.0%, 80.6%, 47.4%, 5.9%, 0.0%, the difference was statistically significant (χ2 = 93.770, P < 0.01), which showed increasing at first and then decreasing, it reached highest point at LSIL , and reached lowest point at AC; positive expression ratio of human telomerase RNA gene were 0.0%, 19.9%, 36.3%, 51.6%, 94.7%, 100.0%, 100.0%, the difference was statistically significant (χ2 = 279.564, P < 0.01), which showed continue increasing, it reached highest point at SCC and AC. According to sequence of normal, inflammation, CIN phase Ⅰ, CIN phase Ⅱ, CIN phase Ⅲ, cervical cancer, positive expression ratio of human papilloma virus L1 protein were 18.6%, 46.1%, 80.6%, 53.3%, 25.0%, 3.6%, the difference was statistically significant (χ2 = 93.015, P < 0.01), which showed increasing at first and then decreasing, it reached highest point at CIN phase Ⅰ, and it reached lowest point at cervical cancer; positive expression ratio of human telomerase RNA gene were 0.0%, 26.4%, 51.6%, 93.3%, 100.0%, 100.0%, the difference was statistically significant (χ2 = 269.582, P < 0.01), which showed continue increasing, it reached highest point at CIN phase Ⅱ. Conclusion Human papilloma virus L1 protein and human telomerase RNA gene combined detection has higher guiding value in cervical precancerous lesions.

宫颈癌是临床常见病症,也是女性特有疾病之一,在恶性肿瘤疾病中,其发病率仅次于乳腺癌[1],每年我国的新发病例和病死病例约为13.5万人和5.0万人[2],且近年来,其发病率持续上升,严重影响着妇女的身体健康,也明显影响患者的预后状况。因而及早诊断和治疗是改善患者的预后,提高患者生活质量的有效手段。目前,临床筛查宫颈癌的临床指标有多种,其中人乳头状瘤病毒L1壳蛋白是评价人乳头状瘤病毒感染状态的有效指标[3-4]。在宫颈细胞由非典型性病变向宫颈癌转变过程中,几乎都伴有3号染色体长臂扩增,且常见片段位于3q26~27,且定位于3q26.3的人端粒酶基因中,因而检测人端粒酶RNA基因有助于筛查宫颈癌[5-6]。……
