Mifepristone (RU486) is marketed and used widely by women as an abortifacient, and experimentally for psychotic depression and anticancer treatments. After administration, metapristone is found to be the most predominant metabolite of mifep…

BACKGROUND: Recent studies showed that inappropriate expression of microRNAs (miRNAs) is strongly associated with tumor-related processes in humans (2-9,11-17). OBJECTIVE: To understand the changes of miRNAs in endometriosis. MATERIALS AN…

BACKGROUND: Cervical cancer is one of the most common cancers in women worldwide, often associated with the infection of human papillomavirus (HPV). Toll-like receptor 8 (TLR8), a pattern recognition receptor, is involved in viral nucleic a…

Human ectopic pregnancy (EP) is a leading cause of pregnancy-related death, but the molecular basis underlying the onset of tubal EP is largely unknown. Female Dicer1 conditional knockout mice are infertile with dysfunctional Fallopian tube…

Endometriosis is a common gynecological disease, yet its pathogenesis remains poorly understood. Recent studies have demonstrated that the aberrant expression of certain microRNAs (miRNAs) may correlate with the development and progression …

Protein phosphatase 2, regulatory subunit A, α (PPP2R1A) and β (PPP2R1B) are paralogous subunits of the heterotrimeric protein phosphatase 2 (PP2A) holoenzyme that catalyzes the dephosphorylation of target substrate proteins. Subtype‑specif…

Neoplasms of the fallopian tube are extremely uncommon. In addition, the incidence of a mature teratoma of the fallopian tube with incomplete uterine mediastinum is extremely low. In the current case report, we present a case of mature cyst…

CONTEXT: Endometrium in polycystic ovary syndrome (PCOS) presents altered gene expression indicating progesterone resistance and predisposing to reduced endometrial receptivity and endometrial cancer. OBJECTIVE: We hypothesized that an alt…

Endometriosis is a common disease in females of reproductive age and has the classic characteristic of mononuclear cell infiltration into lesions. Shikonin is an anti-inflammatory phytocompound obtained from Lithospermum erythrorhizon whose…

BACKGROUND: Disease activity is a major factor in menstrual disorders in systemic lupus erythematosus (SLE) patients not receiving alkylating therapy. However, the ovarian reserve of SLE women with normal menstruation is still unclear. MET…

BACKGROUND: RNA interference technology has shown high therapeutic potential for cancer treatment. However, serum instability, poor tissue permeability and non-specific uptake of short interfering RNA (siRNA) limit its administration in viv…

BACKGROUND: Clear-cell carcinoma transformed from an abdominal wall scar is extremely rare; there are only 22 cases reported in literature. Here we report a case of a patient with clear-cell carcinoma of the abdominal wall after cesarean de…

OBJECTIVES: To explore the effects of progressive muscle relaxation (PMR) training on anxiety, depression and quality of life (QOL) of endometriosis patients under gonadotrophin-releasing hormone (GnRH) agonist therapy. STUDY DESIGN: This …

PROBLEM: To evaluate the effects of the anti-inflammatory and anti-angiogenic roles of LXA4 on endometriosis in mice. METHOD OF STUDY: Endometriosis was induced in 40 mice and separated into two groups. LXA4 group was administered by LXA4 …

OBJECTIVE: Transforming growth factor-1 (TGF-β1), vascular endothelial growth factor (VEGF), and interleukin-10 (IL-10) may be critical cytokines in the microenvironment of a tumor, playing roles in immune suppression. This study was conduc…

OBJECTIVE: To investigate factors with pelvic adhesions and the effect of different degrees pelvic adhesions on fallopian tube recanalization in infertile patients. METHODS: Total of 527 infertile patients undergoing hysteroscopy and lapar…

OBJECTIVE: To investigate the prevalence of infertility and its risk factors in the fertile-age couples of Beijing, China. METHODS: A cross-sectional survey on the prevalence and risk factors was conducted from July 2007 to May 2008 in 7 B…

OBJECTIVE: To determine the feasibility of performing in vivo magnetic resonance elastography (MRE) for uterine leiomyoma. DESIGN: Pilot study. SETTING: Academic medical center. PATIENT(S): Six subjects planning surgical excision of uter…

Primary leiomyoma of the pleura is extremely rare. A 45-year-old man presented with a complaint of right chest pain. Chest computed tomography demonstrated a solid, round pleural mass in the right anterior chest wall. The mass was completel…

OBJECTIVE: To investigate the value of human epididymis secretory protein 4(HE4) combined with CA125 assay in differential diagnosis of endometriosis cyst and ovarian malignant tumor. METHODS: The level of HE4 and CA125 were measured by en…

OBJECTIVE: Polycystic ovary syndrome (PCOS) is associated with the metabolic syndrome. Decreased omentin-1 levels are associated with obesity and diabetes. To study the effects of metformin treatment on omentin-1 levels in PCOS subjects and…

Endometriosis is a chronic disorder affecting approximately 10% of women in whom endometrial tissue forms painful lesions outside the uterus. It has a major impact on their physical, mental and social well-being but has no known cure, and t…

OBJECTIVE: To determine whether polymorphisms of the estrogen receptor alpha (ERalpha) and interleukin-10 (IL-10) genes are associated with endometriosis in a Chinese population. DESIGN: Association study. SETTING: University hospital. P…

Androgens are essential for male development and the maintenance of male secondary characteristics, such as bone mass, muscle mass, body composition, and spermatogenesis. The main disadvantages of steroidal androgens are their undesirable p…

Stressors as subtle as night work or shift work can lead to irregular menstrual cycles, and changes in reproductive hormone profiles can adversely affect bone health. This study was conducted to determine if stresses associated with the dis…
