简要总结
Nonpuerperal mastitis (NPM), mainly including Plasma cell mastitis (PCM) and Granulomatous mastitis (GM), which clinical presentation is an accessible and painful breast mass accompanied by skin redness and swelling, nipple retraction and fistula formation . Much progress has been made in exploring the etiology and pathogenesis of NPM, while the exact etiology remains unknown, NPM is thought to arise from interactions between genetic susceptibility factors, epigenetic effects, and various environmental factors. While microbiota as an environment factor to some inflammatory and autoimmune diseases accept widespread attention, if gut microbiota also as a risk factor for NPM, it is worthy to be considered.
详细描述
NPM is common in young women of reproductive age with a history of lactation and childbearing . The main clinical presentation is an accessible and painful breast mass accompanied by skin redness and swelling, nipple retraction and fistula formation
. The imaging of NPM is not specific, with NPM mimicking breast cancer in imaging . NPM etiology is associated with several factors, such as autoimmunity, bacterial infections , estrogen and progesterone imbalance , and hyperprolactinemia . In recent years, NPM has become a common benign breast disease, especially in the Mediterranean region and developing countries in Asia, such as China . Currently, the associations between bacterial infections and NPM are among the important issues attracting research interest. This study tried to reveal the roles of gut microbiota in NPM. Further understanding of the roles of gut microbiota in this disease may lead to the development of methods for personalized therapy.

结局指标
主要结局
Microbial profiling of Nonpuerperal Mastitis patients and Healthy controls
时间窗: Baseline
16S ribosomal ribonucleic acid(rRNA) gene sequencing technique and illumina MiSeq platform were applied to investigate the difference of gut microbiota richness, diversity and composition between NPM and Healthy controls，and revealing the special gut microbiota profiling data of NPM.
