             [摘    要] 目的:探讨宿主基因 SOX1、JAM3、ZNF671 和 DLX1 的 DNA 甲基化水平在人乳头瘤病毒(human papillomavirus,
              HPV)16/18阳性人群中对宫颈上皮内瘤变2级及以上(cervical intraepithelial neoplasia 2 or worse,CIN2+)的诊断价值,构建风险
              分层模型,为优化宫颈癌筛查策略提供依据。方法:收集2023年4月—2024年5月在东部战区总医院就诊的HPV16/18阳性女
              性宫颈脱落细胞样本共141例,采用基于亚硫酸氢盐转化的焦磷酸测序技术检测上述4个基因的DNA甲基化水平。根据组织
              病理学结果分组,比较 DNA 甲基化水平在不同病变等级(正常、低级别组织学、高级别组织学、癌症)中的差异。进一步以
              CIN2+作为阳性结局,通过Logistic回归构建预测模型,评估模型在训练集和测试集中的诊断效能。结果:4个宿主基因的DNA
              甲基化水平均随病变程度加重而升高,CIN2+组显著高于CIN1-组(P < 0.001),均具有较高的诊断特异性。ZNF671在单基因
              分析中表现最佳,其曲线下面积(area under the curve,AUC)为0.741,联合SOX1构建的模型在训练集与测试集中的AUC分别
              为0.801和0.745,特异性可达87%,优于任意单一基因。结论:SOX1、JAM3、ZNF671和DLX1的DNA甲基化水平与宫颈病变严
              重程度密切相关,具有潜在的分流价值。尤其是在HPV16/18阳性人群中,ZNF671表现出良好的CIN2+预测性能,可作为识别
              癌前病变的辅助决策工具;联合SOX1构建的模型可进一步提高诊断效能。

             [Abstract] Objective:To investigate the diagnostic value of DNA methylation levels of the host genes SOX1,JAM3,ZNF671,and
              DLX1 for cervical intraepithelial neoplasia grade 2 or worse(CIN2+)in women positive for human papillomavirus(HPV)16/18,and to
              construct a risk stratification model to optimize cervical cancer screening strategies. Methods:Cervical exfoliated cell samples were
              collected from HPV16/18⁃positive women attending the General Hospital of Eastern Theater Command between April 2023 and May
              2024. DNA methylation levels of the four host genes were measured using bisulfite⁃converted pyrosequencing. Samples were grouped
              according to histopathological diagnosis(normal,low ⁃ grade histology,high ⁃ grade histology,cancer),and intergroup methylation
              differences were compared. Logistic regression was used to construct a predictive model for CIN2+,and its diagnostic performance was
              assessed in both training and testing datasets. Results:The methylation levels of all four host genes increased progressively with lesion
              severity and were significantly higher in the CIN2 + group than in the CIN1- group(P < 0.001),demonstrating high diagnostic
