Abstract
Plasma cell mastitis (PCM) is a sterile inflammatory condition primarily characterized by periductal inflammation and ductal ectasia. Currently, there is a lack of non-invasive or minimally invasive treatment option other than surgical intervention. The NLRP3 inflammasome has been implicated in the pathogenesis and progression of various inflammatory diseases, however, its involvement in PCM has not yet been reported. In this study, we initially observed the pronounced upregulation of NLRP3 in both human and mouse PCM tissue and elucidated the mechanism underlying the attenuation of PCM through inhibition of NLRP3. We established the PCM murine model and collected samples on day 14, when inflammation reached its peak, for subsequent research purposes. MCC950, an NLRP3 inhibitor, was utilized to effectively ameliorate PCM by significantly reducing plasma cell infiltration in mammary tissue, as well as attenuate the expression of pro-inflammatory cytokines including IL-1β, TNF-α, IL-2, and IL-6. Mechanistically, we observed that MCC950 augmented the function of myeloid-derived suppressor cells (MDSCs), which in turn inhibited the infiltration of plasma cells. Furthermore, it was noted that depleting MDSCs greatly compromised the therapeutic efficacy of MCC950. Collectively, our findings suggest that the administration of MCC950 has the potential to impede the progression of PCM by augmenting MDSCs both numerically and functionally, ultimately treating PCM effectively. This study provides valuable insights into the utilization of pharmacological agents for PCM treatment.

Abstract
Plasma cell mastitis (PCM) is a chronic inflammatory disease of the breast. It is a benign entity mainly found in nonpregnant and nonlactating women. PCM presents with symptoms of inflammation, breast erythema, masses, and indurations. We herein describe a 26-year-old woman with a 2-year history of right breast swelling and a 1-year history of left breast swelling during pregnancy and lactation. She was clinically diagnosed with bilateral breast cancer, but a biopsy specimen revealed PCM. During pregnancy and lactation, PCM can present as bilateral lesions. Early presentation and diagnosis are crucial because PCM, a benign disease, can lead to remarkable morbidity if allowed to progress to an advanced stage.

Abstract
BACKGROUND Plasma cell mastitis (PCM), also known as mammary duct ectasia, is a chronic nonbacterial breast inflammation characterized by duct expansion and plasma cell infiltration. The severe and intense clinical manifestations profoundly affect the quality of life of female patients. Although the pathological process of PCM is known to include four stages (duct dilatation, inflammation, abscess and fistula), there is still lack of imaging techniques and serum markers with high specificity in clinical practice. Due to recurrent acute attacks and the prolonged healing process of the disease, most patients choose to accept mastectomy. SUMMARY We searched for studies, reports and reviews referring to PCM in the past 20 years; more than half of the results were related to animal studies, and little attention has been paid to human beings, which may explain the frequent misdiagnosis of PCM as breast cancer and the limited treatment options. This review focuses on the current diagnostic methods and markers for PCM and hierarchically discusses the typical clinical features, etiological causes and relevant molecular mechanisms of PCM. KEY MESSAGES We herein highlight the urgent need to develop more specific and sensitive biomarkers in the clinical laboratory. It will help to establish a standardized flowchart for the diagnosis and treatment of PCM in order to improve recovery for female patients.

Abstract
Plasma cell mastitis (PCM) and granulomatous mastitis (GM) are the most common inflammatory diseases constituting nonbacterial mastitis (NBM). However, the pathogenesis of NBM remains unclear. In this study, risk factors for NBM were assessed, as well as the pathological features of PCM and GM. The levels of C3/C3a-C3aR and C5/C5a-C5aR1 of tissues were detected by IHC and WB. Exosomes were isolated from serum and identified by transmission electron microscopy. Then, C3 and C5 levels were detected in peripheral blood, and exosomes were assessed by flow cytometry and immunoelectron microscopy. Obesity and prolonged lactation were risk factors for NBM. The infiltration of plasma cells and lymphocytes around the dilated catheter in PCM and the formation of granulomatous structures in GM were the respective pathological features. C3/C3a-C3aR and C5/C5a-C5aR1 levels were elevated in PCM and GM tissue samples. There were no differences in peripheral blood levels of C3 and C5, while C3a and C5a were highly expressed in exosomes. These results suggest that the complement family is activated in PCM and GM, exosomes enrich C3a and C5a, and mediate the spread of inflammation. These findings provide new insights into the molecular mechanisms of PCM and GM and identify therapeutic targets.

Abstract
BACKGROUND Plasma cell mastitis (PCM) is a benign suppurative disease of the breast based on the expansion of mammary ducts and infiltration of plasma cells. It is relatively rare clinically, and its main manifestations include nonperiodic breast pain, nipple discharge, areola lump, nipple depression, nipple fistula, among others. Modern medicine is mainly surgical treatment, which is easy to recur. The clinical practice shows that the overall treatment of patients with TCM syndrome differentiation using oral medicine combined with western medicine therapy, combined internal and external treatment, can significantly improve the curative effect, prevent recurrence, has a certain therapeutic advantage, but lack of evidence of evidence-based medicine. The purpose of this study is to study the efficacy and safety of oral traditional Chinese medicine (TCM) combined with western medicine therapy in the treatment of PCM. METHODS Use computer to retrieve English databases (PubMed, Embase, Web of Science, the Cochrane Library) and Chinese databases (CNKI, Wan Fang, VIP, Chinese biomedical database), from the establishment of database to September 2020, for randomized controlled trials(RCTs) of oral TCM combined with western medicine therapy in the treatment of PCM, two researchers independently extracted the data and evaluated the quality of the included research, and meta-analysis was conducted on the included literatures using RevMan5.3 software. RESULTS This study evaluated the efficacy and safety of oral TCM combined with western medicine therapy in the treatment of PCM from the aspects of effective rate, symptom score, recurrence rate, adverse reaction rate, and patient satisfaction. CONCLUSION This study will provide reliable evidence-based evidence for the clinical application of oral TCM combined with western medicine therapy in the treatment of PCM. ETHICS AND DISSEMINATION The purpose of this study is to sort out and analyze the literature. This systematic review also does not involve endangering participant rights. Ethical approval was not required. The results may be published in a peer-reviewed journal or disseminated at relevant conferences. OSF REGISTRATION NUMBER:: doi 10.17605/OSF.IO/K9A78.

Abstract
OBJECTIVE To evaluate the diagnostic value of ultrasonography and mammography for plasma cell mastitis. METHODS The ultrasonographic and mammographic images of 111 women with histopathologically confirmed plasma cell mastitis were retrospectively analyzed. The diagnostic accuracy of the two imaging methods was compared. RESULTS Ultrasonography identified 91 out of 111 (82.0%) patients with plasma cell mastitis, while the other twenty (18.0%) patients were misdiagnosed. Mammography identified 83 (74.8%) out of 111 patients with plasma cell mastitis. Nineteen (17.1%) patients were misdiagnosed. There was no significant difference between the diagnostic accuracy of using two imaging tests (P = 0.127). Mammography clouds identified 11 out of 20 patients who were not diagnosed by ultrasonography. Meanwhile, 19 of the 28 cases misdiagnosed with mammography were correctly identified by ultrasonography. Overall, 91.9% (102/111) of the patients were identified by the combination of ultrasonography and mammography, which yielded statistically significant higher accuracy than using each single test only (P < 0.05). CONCLUSIONS In diagnosis of plasma cell mastitis, high-frequency ultrasonography and mammography should be combined to improve the diagnostic accuracy.

Periductal Mastitis: An Inflammatory Disease Related to Bacterial Infection and Consequent Immune Responses? Mediators Inflamm 2017; 2017:5309081.

Abstract
Periductal mastitis (PDM) is a prolonged inflammatory disease, but the cause of PDM is poorly understood. In the present case control study, 87 PDM and 87 healthy controls were enrolled and the results were evaluated to identify the significant risk factors for PDM. To investigate the roles of bacterial infection and critical cytokines expression, 16S rRNA gene sequencing and bacterial culturing were conducted. We also measured the levels of interferon-γ, interleukin-12A, and interleukin-17A by semiquantitative immunohistochemistry method. In a multivariable logistic regression model, we identified overweight/obesity and late onset of menarche as independent risk factors for PDM. In contrast, age of first birth >27 years had a protective effect. With 16S rRNA gene sequencing, we confirmed bacterial infections were found in all PDM patients, but none of the control patients was positive on the gene expression of 16S rRNA. Our results also demonstrated significant increases of the IFN-γ and IL-12A expression in PDM, but there was no difference in IL-17A expression in these two groups. Taken together, this study suggests that reproductive factors and overweight/obesity are possible predisposing risk factors for PDM. Bacterial infection and the increased expression of some proinflammatory cytokines are associated with the pathogenesis of this disease.

Abstract
STUDY DESIGN We investigated the association between ICAM-1, -2, -3 plasma levels and ankylosing spondylitis (AS) disease activity. OBJECTIVE In the present study, we aimed to investigate the association between ICAM-1, -2, -3 plasma levels and AS disease activity in the Chinese Han population. SUMMARY OF BACKGROUND DATA AS is a chronic inflammatory rheumatic disease that effects the sacroiliac joints and axial skeleton. The intercellular adhesion molecules (ICAMs) are members of the immunoglobulin superfamily and have been identified to play major roles in inflammation and immune responses. METHODS A total of 60 patients with AS and 60 healthy individuals were selected. The plasma levels of proinflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and ICAM-1, -2, -3, were analyzed by ELISA. Disease severity-related indexes, including the Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), and ankylosing spondylitis disease activity score (ASDAS), were assessed, along with the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level. RESULTS Both ICAM-1 and ICAM-2 levels in plasma were markedly increased in AS patients compared with levels in the plasma of controls. There was no difference between controls and patients in term of ICAM-3 levels. Furthermore, in patients, correlation analysis showed that TNF-α and IL-6 production, as well as the ESR and CRP levels, have positive relationships with ICAM-1 and ICAM-2 plasma levels; the BASDAI, BASFI, and ASDAS scores were also found to be positively correlated with ICAM-2. However, no significant correlations between ICAM-1 levels and BASDAI, BASFI, or ASDAS were detected in our study. CONCLUSION The current findings suggest that ICAM-2 may be a potential biomarker reflecting disease activity and functional ability in AS patients. LEVEL OF EVIDENCE 5.
