摘  要:目的探讨人乳头状瘤病毒(HPV)L1蛋白在宫颈液基细胞学检查异常涂片中的表达及其意义。方法选择2006年9月-2008年9月间,在中日友好医院就诊的宫颈液基细胞学检查诊断为≥未明确诊断意义的不典型鳞状上皮细胞(ASCUS),且其第2代杂交捕获试验(HC-Ⅱ)检测HPVDNA结果均为阳性,同时有组织病理学诊断的患者共274例。其中,宫颈液基细胞学检查诊断为ASCUS105例、低度鳞状上皮内病变(LSIL)119例、不除外高度病变的不典型鳞状上皮细胞(ASC—H)9例、高度鳞状上皮内病变(HSIL)36例、宫颈鳞癌5例;组织病理学检查(作为金标准)诊断为炎症96例、宫颈上皮内瘤变(CIN)Ⅰ85例、CINⅡ55例、CINⅢ32例、宫颈鳞癌6例。对此274例患者的宫颈涂片,采用全反应抗体的免疫细胞化学染色进行HPVL1蛋白的检测,分析其对宫颈病变进展的预测价值。结果274例患者中,组织病理学检查诊断为炎症的组织中HPVL1蛋白阳性表达率为69.8%(67/96),CINI为83.5%(71/85),CINⅡ为41.8%(23/55),CINⅡ为3.1%(1/32),宫颈鳞癌为0(0/6),除CINⅢ与宫颈鳞癌比较,差异无统计学意义(P〉0.05)外,其他不同病变间比较,差异均有统计学意义(P〈0.01);细胞学检查诊断为LSIL的细胞中HPVL1蛋白阳性表达率(75.6%,90/119)最高,其次为ASCUS细胞(63.8%,67/105)和HSIL+宫颈鳞癌细胞(9.8%,4/41),3者间比较,差异有统计学意义(P〈0.01)。71例未经治疗的ASCUS、LSIL患者中,55例HPVL1蛋白阳性表达者中无一例疾病进展,16例HPVL1蛋白阴性表达者疾病进展的发生率为19%(3/16),两者比较,差异有统计学意义(P〈0.01)。结论HPVL1蛋白在宫颈液基细胞学检查异常涂片中的表达情况可以帮助了解宫颈的病变程度,预测宫颈病变的发展趋势,尤其对�Objective To investigate the possibility of detection of the human papillomavirus (HPV) L1 capsid protein to predict the course of mild or moderate cervical intraepithelial neoplasia (CIN). Methods Immunocytochemical analysis using antibody against HPV L1 capsid protein was carried out on 274 samples obtained from women performed TriPath Pap tests, positive for high-risk HPV DNA detected by hybrid capture Ⅱ ( HC- Ⅱ ) or cytologic diagnosed atypical squamous cells of undetermined significance (ASCUS) or more severe. For cytological diagnosed, there were ASCUS 105 cases, low-grade squamous intraepithelial lesions (LSIL) 119 cases, atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H) 9 cases, high-grade squamous intraepithelial lesions (HSIL) 36 cases, and squamous cell carcinoma (SCC) 5 cases. But for the pathologic diagnosed, there were chronic cervicitis 96 cases, CIN I 85 cases,CIN Ⅱ 55 cases, CIN Ⅲ 32 cases, and SCC 6 cases. Results Of the 274 cases, HPV L1 capsid protein was positive in 69.8% (67/96) of cervicitis, 83.5% (71/85) of CIN Ⅰ , 41.8% (23/55) of CIN Ⅱ, 3.1% (1/32) of CINⅢ and 0(0/6) of SCC. Cytologic diagnosis revealed a higher expression rate in LSIL (75.6%, 90/119) than that in ASCUS (63.8% , 67/105 ) or in HSIL + SCC (9.8% ,4/41 ;all P 〈0.01 ). Of 71 cases with ASCUS and LSIL without treated, none of HPV L1 positive cases (0/55) progressed in cytology, while 19% (3/16) of HPV L1 negative cases progressed to ASC-H, HSIL (P 〈 0. 01 ). Conclusion The expression rates of HPV L1 protein in liquid-based cell specimen is decreased as the cytopathology diagnosis severe degree, which may imply the histopathology diagnosis of cervix, predict the progression of cervical lesion, and help to treat the cases with ASCUS and LSIL
