目的 分析阴道灌洗液中炎性因子表达水平与高危型人乳头瘤病毒(HPV)持续感染的相关性。方法 选择本院2019年3月—2021年3月接诊的80例高危型HPV持续感染患者作为试验组,以病理组织检查结果分组,将19例宫颈癌患者作为试验组1、将30例宫颈上皮不典型增生(CIN)I级患者作为试验组2,将31例CIN II、III级患者作为试验组3,选取同期门诊体检的30例健康女性作为对照组,均进行TGF-β、IFN-γ、IL-17、IL-6表达水平检测,比较4组TGF-β、IFN-γ、IL-17、IL-6水平、高危型HPV负荷量,Pearson分析TGF-β、IFN-γ、IL-17、IL-6水平与高危型HPV负荷量的相关性。结果 阴道灌洗液炎症因子水平、高危型HPV负荷量4组相比较,差异均有统计学意义(P<0.05)。TGF-β、IL-17、IL-6水平与高危型HPV负荷量呈正相关性,与IFN-γ水平呈负相关性,P＜0.05。结论 高危型HPV持续感染患者机体阴道灌洗液中炎性因子水平与高危型HPV负荷量存在一定的相关性,高危型HPV负荷量与IFN-γ水平呈负相关性,与TGF-β、IL-17、IL-6水平呈正相关性,通过检测阴道灌洗液中炎性因子水平,可评估HPV感染程度。

Objective To analyze the correlation between the expressions of inflammatory factors in vaginal lavage fluid and persistent infection of high-risk human papillomavirus(HR-HPV). Methods A total of 80 patients with HR-HPV persistent infection in our hospital from March 2019 to March 2021 were selected as the experimental group. According to the pathological examination results, 19 patients with cervical cancer were selected as the experimental group 1, 30 patients with CIN grade I were selected as the experimental group 2, and 31 patients with CIN grade II and III were selected as the experimental group 3. Thirty healthy women in the same period were selected as the control group. HR-HPV load, TGF- β, IFN-γ, IL-17 and IL-6 levels were detected and were compared among the four groups. Pearson analysis of correlation between TGF- β, IFN-γ, IL-17, IL-6 levels and HR-HPV load was carried out. Results There were significant differences in the levels of inflammatory factors in vaginal lavage fluid and HR-HPV load among the four groups (P<0.05). TGF- β、IL-17 and IL-6 levels were positively correlated with HR-HPV load and negatively correlated with IFN-γ (P<0.05). Conclusions There is a certain correlation between inflammatory factors in vaginal lavage fluid and HR-HPV load in patients with HR-HPV persistent infection. HR-HPV load is negatively correlated with IFN-γ, and positively correlated with TGF-β, IL-17 and IL-6. The degree of HPV infection could be evaluated by detecting the inflammatory factors in vaginal lavage fluid.
