研究目的:

通过16S rRNA基因扩增技术,比较妊娠期糖尿病孕妇与健康孕妇口腔、胎盘、阴道和肠道菌群的组成及结构特征差异(多样性、优势菌群、特有菌群等),阐明口腔、胎盘、阴道和肠道菌群的关联性、共变特征;通过相关网络分析,进一步探讨妊娠期糖尿病孕妇菌群与母婴血糖及炎性标志物的相关性,筛选与GDM 发生、血糖水平显著相关的多部位关键差异菌群,识别潜在微生态标志物,为GDM预警提供菌群依据,进而为GDM的管理提供新的方向。  

Objectives of Study:

Using 16S rRNA gene amplicon sequencing, we will compare the composition and structural characteristics (including diversity, dominant microbiota, and specific bacterial taxa) of the oral, placental, vaginal, and gut microbiota between pregnant women with gestational diabetes mellitus (GDM) and healthy controls. We aim to elucidate the inter-niche correlations and covariation patterns among these four body sites. Through correlation network analysis, we will further investigate the associations between maternal multi-site microbiota and maternal-fetal glycemic levels as well as inflammatory biomarkers. Ultimately, we seek to screen for key differential bacteria across multiple body sites that are significantly associated with GDM occurrence and glucose metabolism, identify potential microecological markers, and provide a microbial basis for early warning of GDM, thereby offering novel directions for GDM management.
