The homeostasis balance of copper, as an essential trace element for life activities, is crucial for maintaining the normal function of cells. Cuproptosis, discovered in recent years, is a novel type of programmed cell death triggered by th…

Ovarian cancer is one of the most lethal gynecological malignancies globally, with significant variations in incidence, prevalence, and outcomes across regions and population subgroups. This study systematically evaluates the global, region…

OBJECTIVE: To determine the future priorities for ectopic pregnancy research. DESIGN: Potential research questions were collated from an initial international survey, a systematic review of clinical practice guidelines, and Cochrane system…

RESEARCH QUESTION: How does tubal endometriosis (TEM) impact the morphology and ultrastructure of tubal epithelium, and what are the underlying pathophysiological mechanisms of TEM? DESIGN: Epithelial samples of fallopian tube were collect…

We report two cases of heterotopic intramural ectopic pregnancy (HIMP) following multiple abortions, with lesions located near the uterine fundus or uterine horn. These cases are particularly challenging to diagnose using early two-dimensio…

Natural killer (NK) cells, serving as pivotal mediators of innate immunity, play an important role in antitumor immunity. Immune checkpoint can be expressed on the surface of NK cells and meticulously regulates their activation states and e…

PURPOSE: To investigate and compare the clinical characteristics and risk factors between intrinsic and extrinsic adenomyosis (AM), as well as the differences in their perioperative management and findings in the two subtypes. METHODS: Thi…

INTRODUCTION: A symptomatic uterine niche is a long-term complication after a cesarean section (CS). A group of international niche experts reached consensus on a standardized definition of a disorder caused by a symptomatic niche, named ce…

OBJECTIVE: To analyze the value of serum human chorionic gonadotropin (β-HCG), anti-Mullerian hormone (AMH), progesterone (P)/ estradiol (E2) in predicting the pregnancy outcome of frozen-thawed embryo transfer (FET) cycle in patients with …

BACKGROUND: Surgery for adnexal mass does occur in pregnant women and therefore the choice of surgery during pregnancy needs to be carefully considered and studied. This study aimed to evaluate the safety and feasibility of Laparo-endoscopi…

In the last decade, organoid research has entered a golden era, signifying a pivotal shift in the biomedical landscape. The year 2023 marked a milestone with the publication of thousands of papers in this arena, reflecting exponential growt…

INTRODUCTION: Endometriosis (EM) is an estrogen-dependent benign gynecologic disease affecting approximately 10% of reproductive-age women with a high recurrence rate, but lacks reliable biomarkers. No previous studies have investigated the…

BACKGROUND: Ensuring women's sexual and reproductive health (SRH) is a fundamental human right and key to 2030 agenda of the UN Sustainable Development Goals (SDGs), yet limited evidence exists on SRH in China, including national estimates …

Long non-coding RNAs play critical roles in the development of lung cancer by functioning as tumor suppressors or oncogenes. Changes in the expression of LINC01279 have been associated with cell differentiation and human diseases. However, …

BACKGROUND: Endometriosis (EM) is a hormone-dependent condition marked by progressively severe secondary dysmenorrhea, significantly impacting patients' quality of life and overall health. Wen Jing Tang (WJT), a traditional Chinese medicina…

BACKGROUND: Accurate preoperative assessment of the efficacy of high-intensity focused ultrasound (HIFU) ablation for uterine fibroids is essential for good treatment results. The aim of this study was to develop robust radiomics models for…

BACKGROUND: Laparoscopic tubal anastomosis (LTA) is a treatment for women who require reproduction after ligation, and there are no reliable prediction models or clinically useful tools for predicting clinical pregnancy in women who receive…

Endometriosis is a gynecological disease related to menstruation that affects nearly 10% of reproductive-age women. However, so far, there are no reliable diagnostic biomarkers for endometriosis, causing a delay in diagnosis of 6.7 ± 6.2 ye…

AbstractAdenomyosis (AM) is a common gynecological condition that can be classified into different subtypes. This study aimed to evaluate the clinical characteristics, factors and treatment effect in women who diagnosed with intrinsic or ex…

RESEARCH QUESTION: What is the effect of tubal endometriosis on tubal epithelial ultrastructure and is there a differential expression of exosomal microRNAs (miRNAs) in tubal fluid which may affect tubal infertility? DESIGN: Human fallopia…

Objective: To investigate the impact of endometriosis (EMS) on granulosa cell function and elucidate the molecular mechanisms involved. Methods: RNA sequencing, differential expression analysis, Gene Ontology (GO) and Kyoto Encyclopedia of …

INTRODUCTION: Cesarean scar defect (CSD) is a long-term outcome of cesarean section (CS) and associated with numerous gynecological and obstetric problems. Previous studies indicate that infection may be a risk factor for CSD. Adjunctive az…

Pregnancy loss (PL) is one of the common complications that women can experience during pregnancy, with an occurrence rate of 1 to 5%. The potential causes of pregnancy loss are unclear, with no effective treatment modalities being availabl…
