Dioxins are persistent environmental pollutants known for their multiple health effects, from skin rashes to liver dysfunction, reproductive toxicity and cancer. While the hazards of dioxins have been well documented, the challenge of devel…

Relative Fat Mass (RFM) is an emerging body fat measurement index that more accurately reflects the distribution of visceral fat. This study aimed to investigate the association between RFM and female infertility. We utilized data from the …

OBJECTIVE: This study aimed to compare the perioperative outcomes of single-incision laparoscopic surgery (SILS) and dual-port laparoscopic myomectomy in patients with solitary uterine fibroids. METHODS: This retrospective observational st…

OBJECTIVE: To compare the outcomes of hysterectomy performed via traditional inpatient procedure versus day-care procedure with a focus on surgical time, post-operative recovery, costs, and patient satisfaction, using propensity score match…

The aim of the case control study was to compare surgical outcomes of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) hysterectomy with the da Vinci surgical system (dVSS) and conventional vNOTES. A case control study …

Endometrial cancer (EC) is a fatal gynecologic tumor. Bioinformatic tools are increasingly developed to screen out molecular targets related to EC. Our study aimed to identify stemness-related prognostic biomarkers for new therapeutic strat…

This study aims to objectively assess the effect of three surgical approaches for posterior uterine fibroid resection: transumbilical laparoendoscopic single-site surgery (LESS), vaginal natural orifice transluminal endoscopic surgery (vNOT…

BACKGROUND: Cadmium (Cd), lead (Pb), and mercury (Hg) have been shown to exhibit endocrine disrupting properties. Their effects on women's reproductive health, however, remain elusive. Here, we investigated associations between blood concen…

OBJECTIVE: To assess the perioperative outcomes of vNOTES tubal surgeries and to identify predictors of surgical conversion. METHODS: A single-center retrospective cohort study was performed on 619 patients who underwent vNOTES tubal surge…

STUDY OBJECTIVE: To describe the surgical technique and compare the operative outcomes of gasless and traditional robot-assisted transvaginal natural orifice transluminal endoscopic surgery (GR-vNOTES vs. TR-vNOTES) in hysterectomy. METHOD…

INTRODUCTION: As a new minimally invasive surgery, transvaginal natural orifice transluminal endoscopic surgery (vNOTES) has been proved to be suitable for the treatment of a variety of gynecological benign diseases. However, compared with …

The need for long-term treatments of chronic diseases has motivated the widespread development of long-acting parenteral formulations (LAPFs) with the aim of improving drug pharmacokinetics and therapeutic efficacy. LAPFs have been proven t…

Chronic myelocytic leukemia (CML) is characterized by increased and unregulated growth of predominantly myeloid cells in the bone marrow, and accumulation of these cells in blood. We investigated the effects of an anti-malarial drug, dihydr…

Endometriosis is an estrogen-dependent disease that can impair fertility in women of reproductive age. Approximately 30–58 % of infertile women have complication owing to this disease, and the incidence

Objective To study the expression of leptin and leptin receptor (Ob-R)in ectopic and eutopic endometrium from women with ovarian endometriosis(EMs), and to explore their role in pathogenesis of ovarian endometriosis. Methods Twenty-f…

PROBLEM: To explore the roles of leptin, monocyte chemotactic protein (MCP)-1, and tumour necrosis factor (TNF)-α in the peritoneal fluid (PF) in the pathogenesis of endometriosis-associated infertility. METHOD OF STUDY: Leptin, MCP-1, and…

Objective:To establish a HPLC method for the determination of megestrol acetate in rat plasma.Methods:After being extracted by hexane with danazol as internal standard(IS),the plasma sample was analyzed on a Thermo BDS Hypersil C18 column(2…
