Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Microbial profiling of Nonpuerperal Mastitis patients and Healthy controls

    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.

    Baseline

Secondary Outcomes (1)

  • Metabolic profiling of Nonpuerperal Mastitis patients and Healthy controls

    Baseline

Other Outcomes (1)

  • Serum Levels of Immune factor

    Baseline

Study Arms (2)

Control group

40 healthy volunteers were included in the healthy control group

NPM group

60 patients of NPM (30 PCM and 30 GM)were included
