摘 要:目的探讨人乳头状瘤病毒(HPV)E6/E7mRNA在筛检宫颈癌前病变-子宫颈上皮内瘤变(CIN)2级及以上CIN2+(CINⅡ和CIN11I)病变的应用价值。方法横断面调查设计,标本来源于2011年12月至2013年12月期间惠州市第一人民医院和惠州市第三人民医院妇产科门诊和住院部宫颈疾病疑似患者,采集345例妇女宫颈脱落细胞用支链DNA(b-DNA)技术检测高危HPVE6/E7mRNA,以液基细胞学(thin—prepcytologictest,TCT)和组织病理学结果为参照,对HPVE6/E7mRNA的临床CIN诊断价值进行效能分析。结果(1)与TCT比较:325例HPVE6/E7mRNA阳性率分别为:未见上皮内病变细胞(NILM)21.1%(40/190)、非典型鳞状细胞(ASC)38.5%(15/39)、低度鳞状上皮内病变(LSIL)76.9%(30/39)、非典型鳞状细胞不能排除高级别上皮内病变(ASC—H)8/10、高度鳞状上皮内病变(HSIL)72.3%(34/47),TCT分级与HPVE6/E7mRNA阳性率呈线性关联(x。=67.654,P〈0.01;r=0.497,P〈0.01);与HPVE6/E7mRNA拷贝数也具有相关性(r=0.511,P〈0.01)。(2)与病理结果比较:164例HPVE6/E7mRNA阳性率分别为NILM27.8%(10/36)、CINI65.9%(29/44)、CIN1180.6%(54/67)、CINⅢ82.4%(14/17),病理分级与HPVE6/E7mRNA阳性率呈线性关联(x。=26.426,P〈0.01;r=0.438,P〈0.01);与HPVE6/E7mRNA拷贝数具有相关性(r=0.543,尸〈0.01)。(3)筛检效能分析:HPVE6/E7mRNA敏感度为84.6%、TCT敏感度为47.7%,联合序贯检测时敏感度为40.0%,特异度为91.1%;受试者工作特征曲线确定的CIN2+(CINn和CINHI)最佳诊断临界点为890.26个拷贝/ml,敏感度为58.5%,特异度为93.7%。结论HPVE6/E7mRNA检测对宫颈病变检出率优于TCT,联合序贯检测时特异度明显提高;采用最佳诊断临界点进行分析时,检出CIN2-4Objective This study aimed to explore the clinical value of human papilloma virus (HPV) E6/E7 mRNA tests in identifying precancerous lesions of the uterine cervix- cervical intraepithelial neoplasia 2 or more CIN2 + ( CIN II and CIN m ). Methods This study is a cross-sectional survey design, between December 2011 to December 2013. The specimens were collected from the First People's Hospital of Huizhou and the Third People's Hospital of Huizhou in Department of Obstetrics and Gynecology outpatient and inpatient of cervical disease suspected patients, with thin-prep cytologic test (TCT) and histopathological results as reference, detected 345 patients of exfoliated cervical epithelial cells by using the branched DNA (b-DNA) technology to evaluate the application value of high risk HPV E6~/ETmRNA in the clinical diagnosis of CIN. Using spss 19.0 software for data analysis. Results ( 1 ) Compared with TCT, the positive rate of E6/E7 mRNA in 325 samples were grading by cytology as follows: no intraepithelial lesion cells (NILM) 21.1% (40/190), atypical squamous cells (ASC) 38. 5% (15/39), low-grade squamous intraepithelial lesions (LSIL) 76. 9% (30/39), atypical squamous cells can not exclude high-grade intraepithelial lesions (ASC-H) (8/10) , high-grade squamous intraepithelial lesions (HSIL) 72. 3 % ( 34/ 47), TCT grades and HPV E6/E7 mRNA positive rate showed linear association (X2 = 67. 654 ,P 〈 0. 01; r =0. 497, P 〈 0. 01 ) ; and with HPV E6/E7 mRNA copy number was also relevant ( r = 0. 511, P 〈 0. 01 ). (2) Compared with pathological results, the positive rate of E6/E7 mRNA in 164 women samples were grading by pathology as follows: with NILM was 27.8% (10/36), with CIN I was 65.9% (29/44), with CIN I/ was 80. 6% (54/67) , and with CINm was 82. 4% (14/17) , pathological grades and HPV E6/ E7 mRNA positive rate showed a linear correlation ( X2 = 26. 426, P 〈 0. 01 ; r = 0. 438, P 〈 0.01 ) ; and the num
