简要总结
Endometriosis (EM) is a common gynecological condition, but the pathogenesis of it has not yet been clarified. Here, the investigators wanted to investigate the correlation between endometriosis and the intra-tissue microbiota. The investigators planed to collect serum, vaginal swabs, cervical mucus, feces, peritoneal fluid, and endometrial tissue for sequencing and experiments.
详细描述
Endometriosis (EM) is a common gynecological condition that occurs in women of reproductive age and is characterized by pain, masses, and infertility. EM is a tumor-like disease that is invasive, metastatic, recurrent, but the pathogenesis of EM has not yet been clarified. Advances in the study of intratumoral microbiota provided increasing evidence confirming the presence and mechanism of bacteria in tumor tissues. Therefore, the investigators wanted to investigate the correlation between endometriosis and its microbiota in the endometrial tissue.
Participants in this study will be recruited in the obstetrics and Obstetrics and Gynecology Medical Center of Zhujiang Hospital. With reference to the inclusion and exclusion criteria, patients admitted for surgery were under screening. Participants were assigned to Endometriosis group after confirmation by laparoscopy together with biopsy analysis, while the control group was identified as non-EM patients, usually with benign gynecologic conditions such as uterine fibroids or teratomas.
The investigators will obtain serum, vaginal swabs, cervical mucus, and feces from the participant before surgery. The peritoneal fluid, eutopic endometrium, and ectopic endometrium lesion will also be collected if the surgical approach allows. The specimens will be sent for microbiota sequencing, transcriptome sequencing, metabolome sequencing, single cell sequencing, and laboratory experiments.

结局指标
主要结局
Metagenomics Next Generation Sequencing of the Intra-tissue Microbiota Composition
时间窗: 3 years
Using metagenomics sequencing of microbiota, compare the microbial composition differences of specimens derived from EM group and control group, including the alpha diversity(Shannon index, Simpson index, etc.), beta diversity(PCoA analysis, Bray-Curtis, etc.) differential taxonomy, and KEGG pathway prediction.
