研究目的:

系统比较EPs患者伴与不伴CE阴道微生态的组成、结构和功能差异,探讨阴道微生态特征在合并CE的EPs发生发展中的潜在作用,为临床诊断和治疗提供新思路。 具体目的包括: 1.分析EPs患者伴与不伴CE阴道微生态组成特征的差异,包括菌群多样性、优势菌群、条件致病菌等的差异; 2.比较两组患者阴道微生态功能潜能的差异,通过宏基因组学分析预测微生物群落的功能特征; 3.探讨阴道微生态特征与合并CE的EPs临床表现和病理特征的相关性; 4.评估阴道微生态指标对EPs患者伴CE的辅助诊断价值。  

Objectives of Study:

To systematically compare the composition, structure and functional differences of vaginal microbiota in patients with endometrial polyps (EPs) with and without chronic endometritis (CE), to explore the potential role of vaginal microbiota characteristics in the occurrence and development of EPs complicated with CE, and to provide new ideas for clinical diagnosis and treatment.Specific objectives include: 1.To analyze the differences in vaginal microbiota composition between EPs patients with and without CE, including differences in microbial diversity, dominant flora, opportunistic pathogens, etc; 2.To compare the differences in functional potential of vaginal microbiota between the two groups, and to predict the functional characteristics of microbial communities through metagenomic analysis; 3.To explore the correlation between vaginal microbiota characteristics and clinical and pathological features of EPs complicated with CE; 4.To evaluate the auxiliary diagnostic value of vaginal microbiota indicators for EPs patients with CE.
