BACKGROUND: Recurrent implantation failure (RIF) is a major challenge in in vitro fertilization (IVF). The window of implantation (WOI) is the endometrium’s receptive period for embryos, and endometrial receptivity analysis (ERA) is a poten…

BACKGROUND: Adenomyosis (AM) is a common gynecological disorder in reproductive-age women, with impaired endometrial receptivity as a key contributor to infertility. However, a comprehensive single-cell atlas of the eutopic endometrium duri…

OBJECTIVES: To explore the clinical relevant factors of patients with recurrent and non-recurrent abdominal wall endometriosis after surgical treatment, to further study the relevant risk factors of abdominal wall endometriosis recurrence, …

OBJECTIVE: Cesarean section (CS) rates have risen globally, with cesarean scar defect (CSD) being a common complication. Few studies have investigated the impact of CSD on in vitro fertilization/intracytoplasmic sperm injection frozen embry…

Reduced lymphoid enhancer-binding factor 1 (LEF1) expression in patients with adenomyosis during the mid-secretory phase leads to impaired endometrial receptivity, affecting embryo implantation. This study investigated the molecular mechani…

Inflammatory diseases, including autoimmune, infectious, and metabolic disorders, remain major global health challenges due to their complex pathogenesis and limited therapeutic options. In recent years, bioinspired nanotechnology has emerg…

BACKGROUND: The chronic inflammatory immune response is a significant factor in the pathogenesis of benign gynecological diseases. The systemic immunoinflammatory index (SII) and the platelet-to-lymphocyte ratio (PLR) are commonly available…

Accumulating researches have reported that miR-17-92 cluster expression has strong association with tumorigenesis. In this study, we investigated the effects of 2 genetic polymorphisms in the promoter region of the miR-17-92 cluster and the…

OBJECTIVE: Progesterone receptor membrane component 2 (PGRMC2) belongs to the membrane-associated progesterone receptor family, which regulates multiple pathophysiological processes. However, the role of PGRMC2 in ischemic stroke remains un…

Sclerosing stromal tumors of the ovary are benign and tend to occur in youthful women with lobular structures at low frequencies. Three types of cells, including luteinized cells, short spindle myoid cells, and intermediate cells, are found…

Carnitine metabolism is thought to be negatively correlated with the progression of hepatocellular carcinoma (HCC) and the specific molecular mechanism is yet to be fully elucidated. Here, we report that little characterized cysteine-rich p…

BACKGROUND: A large number of our previous studies showed that endogenous glutamate and N-methyl-D-aspartate receptor (NMDAR) activation may be involved in various types of acute lung injury, airway inflammation, asthma, and pulmonary fibro…

Objective: To evaluate the efficacy and safety of dienogest (DNG) in the treatment of refractory endometriosis-associated pain (REAP). Methods: In this study, REAP was defined according to the following criteria: (1) the pain duration was ≥…

Inadequate endometrial receptivity may be responsible for the low implantation rate of transferred embryos in in vitro fertilization (IVF) treatments. Patients with repeated implantation failure (RIF) impact the clinical pregnancy rate for …

Objective To study the clinical effect of laparoscopic excision of ovarian cyst in the treatment of patients with ovarian cyst. Methods From August 2016 to August 2018, 106 patients with ovarian cyst were selected in the Second Peopl…

As a class of transcription regulators, numerous miRNAs have been verified to participate in regulating ovary follicular development in chickens (Gallus gallus). Previously we showed that gga-miR-135a-5p has significant differential express…

Plaque psoriasis is a chronic inflammatory skin disease that affects a substantial proportion of the world population. This disorder is characterized by scaly, thick skin, intense ongoing itch, and itch from light touch (such as clothing co…

BACKGROUND: Intrauterine adhesions (IUA) are the most common cause of uterine infertility and are caused by endometrium fibrotic regeneration following severe damage to the endometrium. Although current stem cell treatment options using dif…

Steroidogenic factor-1 (SF-1, encoded by NR5A1) and estrogen receptor beta (ERβ, encoded by ESR2), which are highly expressed in endometriotic stromal cells (ESCs), contribute to the pathogenesis of endometriosis, but the regulation mechani…

UNLABELLED: Estrogen receptor beta (ERβ, encoded by ESR2 gene) and cytochrome P450 aromatase (encoded by CYP19A1 gene) play critical roles in endometriosis, and the levels of insulin-like growth factor-I (IGF-I) in the peritoneal fluid are …

Overexpression of annexin A2 (Anxa2) is correlated with invasion and metastasis in breast cancer cells. In this study, breast cancer patients with upregulated Anxa2 exhibited poor overall and disease-free survival rates. Anxa2 expression wa…

CONTEXT: Endometriosis is an estrogen-dependent disease. P38 and C-jun NH2-terminal kinase (JNK) inhibitors may have a therapeutic effect on endometriosis through regulation of prostaglandin E2 (PGE2)-induced estrogen metabolism. OBJECTIVE…

BACKGROUND: Cytochrome P450 aromatase (encoded by the CYP19A1/aromatase gene) plays a critical physiologic role in endometriosis. Metformin is known to suppress prostaglandin E2 (PGE2)-induced CYP19A1 messenger RNA (mRNA) expression in huma…
