LSIL患者阴道微生态指标和细胞因子与HPV感染的相关性研究

LSIL患者阴道微生态指标和细胞因子与HPV感染的相关性研究摘要：

目的：本研究旨在探究LSIL患者阴道微生态指标和细胞因子与HPV感染的相关性，为临床治疗、预防和干预提供科学依据。

方法：选取60例LSIL患者，并分别于初诊前采集阴道分泌物，检测HPV感染情况，并测定细胞因子IL-1、IL-6、IL-8、TNF-α、IFN-γ、IL-10的水平；同时对样本进行16SrRNA基因测序，获得阴道微生态组成，并进行分析。

结果：LSIL患者中，HPV感染率达到63.3%。与HPV感染阴性组相比，HPV感染阳性组IL-1、IL-6、IL-8、TNF-α、IFN-γ、IL-10的水平均明显升高。微生态学研究表明，阴道微生物组成存在明显差异。HPV感染阳性组，典型的乳酸杆菌属Lactobacillus占优势，其他蜕变菌种类丰度较低，菌群稳定；而HPV感染阴性组中，阴道内分泌液pH值较高，Anaerococcus、Megasphaera等潜在致病菌丰度增加，菌群不稳定。多个物种与细胞因子水平存在相关性，HPV感染和细菌的变异与细胞因子水平的改变密切相关。

结论：LSIL患者阴道微生态和细胞因子与HPV感染密切相关，阴道微生态失衡和某些细胞因子的水平变化，可能是影响LSIL患者易感染HPV的主要原因，可为临床治疗、预防和干预提供重要的参考价值。
