Creatine promotes endometriosis progression by inducing M2 polarization of peritoneal macrophages.

Endometriosis is a chronic inflammatory disease characterized by the growth of endometrium-like tissues outside the uterine cavity, with an unclear pathogenesis. Analysis of single-cell sequencing data revealed the pivotal role of peritoneal macrophages in the development of endometriosis. We noted significant creatine enrichment and synthesis in peritoneal macrophages of patients with endometriosis compared to women without endometriosis.

Creatine Promotes Endometriosis by Inducing Ferroptosis Resistance via Suppression of PrP.

Endometriosis, a chronic inflammatory disease, significantly impairs the quality of life of women in their reproductive years; however, its pathogenesis remains poorly understood. The accumulation of retrograde menstruation and recurrent bleeding fosters a high-iron environment in ectopic lesions, triggering ferroptosis in ectopic endometrial stromal cells (EESCs), thereby hindering the establishment of endometriosis. However, abnormal EESCs demonstrate resistance to ferroptosis in high-iron environments, promoting the progression of this disease.

Efferocytosis by macrophages in physiological and pathological conditions: regulatory pathways and molecular mechanisms.

Efferocytosis is defined as the highly effective phagocytic removal of apoptotic cells (ACs) by professional or non-professional phagocytes. Tissue-resident professional phagocytes ("efferocytes"), such as macrophages, have high phagocytic capacity and are crucial to resolve inflammation and aid in homeostasis. Recently, numerous exciting discoveries have revealed divergent (and even diametrically opposite) findings regarding metabolic immune reprogramming associated with efferocytosis by macrophages.

Heme induced progesterone-resistant profiling and promotion of endometriosis in vitro and in vivo.

Endometriosis is an estrogen-dependent, progesterone-resistant gynecological disease with an unknown pathogenesis. Compared to women without endometriosis, women with endometriosis have a remarkably high heme level in the peritoneal fluid. To further investigate the pathomechanisms of heme in endometriosis, we aimed to identify the dysregulated expression of heme-trafficking proteins, such as PGRMC1/2 that are also receptors that mediate the non-genomic responses to progesterone, and heme-degrading enzymes between ectopic endometrial stromal cells and their normal counterparts.

Peritoneal immune microenvironment of endometriosis: Role and therapeutic perspectives.

Endometriosis, an estrogen-dependent chronic inflammatory disease characterized by the growth of endometrium-like tissues outside the uterine cavity, affects 10% of reproductive-age women. Although the pathogenesis of endometriosis is uncertain, it is widely accepted that retrograde menstruation results in ectopic endometrial tissue implantation. Given that not all women with retrograde menstruation develop endometriosis, immune factors have been hypothesized to affect the pathogenesis of endometriosis.

Health status, care needs, and assessment for beneficiaries with or without dementia in a public long-term care insurance pilot in Guangzhou, China.

Background: Chinese government launched a pilot study on public long-term care insurance (LTCI) recently. Guangzhou is one of the fifteen pilot cities, officially started providing LTCI in August 2017. An in-depth analysis of experimental data from the pilot city may provide suggestions for developing a fair and effective LTCI system.

Validation of the Chinese version of the abnormal eating behavior questionnaire in people with dementia.

Abnormal eating behaviors are common in patients with dementia. To comprehensively assess and understand these issues, we validated the Chinese version of the Abnormal Eating Behaviour Questionnaire. Data for psychometric property evaluation were obtained from 129 patients with dementia.
