LSIL患者陰道微生態(tài)指標和細胞因子與HPV感染的相關(guān)性研究

LSIL患者陰道微生態(tài)指標和細胞因子與HPV感染的相關(guān)性研究摘要：

目的：本研究旨在探究LSIL患者陰道微生態(tài)指標和細胞因子與HPV感染的相關(guān)性，為臨床治療、預(yù)防和干預(yù)提供科學(xué)依據(jù)。

方法：選取60例LSIL患者，并分別于初診前采集陰道分泌物，檢測HPV感染情況，并測定細胞因子IL-1、IL-6、IL-8、TNF-α、IFN-γ、IL-10的水平；同時對樣本進行16SrRNA基因測序，獲得陰道微生態(tài)組成，并進行分析。

結(jié)果：LSIL患者中，HPV感染率達到63.3%。與HPV感染陰性組相比，HPV感染陽性組IL-1、IL-6、IL-8、TNF-α、IFN-γ、IL-10的水平均明顯升高。微生態(tài)學(xué)研究表明，陰道微生物組成存在明顯差異。HPV感染陽性組，典型的乳酸桿菌屬Lactobacillus占優(yōu)勢，其他蛻變菌種類豐度較低，菌群穩(wěn)定；而HPV感染陰性組中，陰道內(nèi)分泌液pH值較高，Anaerococcus、Megasphaera等潛在致病菌豐度增加，菌群不穩(wěn)定。多個物種與細胞因子水平存在相關(guān)性，HPV感染和細菌的變異與細胞因子水平的改變密切相關(guān)。

結(jié)論：LSIL患者陰道微生態(tài)和細胞因子與HPV感染密切相關(guān)，陰道微生態(tài)失衡和某些細胞因子的水平變化，可能是影響LSIL患者易感染HPV的主要原因，可為臨床治療、預(yù)防和干預(yù)提供重要的參考價值。

Title：Correlationbetweenvaginalmicrobiota,cytokinesandHPVinfectioninLSILpatients

Abstract：

Objective:Theaimofthisstudywastoexplorethecorrelationbetweenvaginalmicrobiota,cytokines,andHPVinfectioninLSILpatientsandprovideascientificbasisforclinicaltreatment,prevention,andintervention.

Methods:60LSILpatientswereselected,andvaginalsecretionswerecollectedbeforeinitialdiagnosistodetectHPVinfectionandmeasurethelevelsofcytokinesIL-1,IL-6,IL-8,TNF-α,IFN-γ,andIL-10.Simultaneously,the16SrRNAgenesequencingwasappliedforvaginalmicrobiotaanalysis.
