INTRODUCTION: Tamoxifen is a cornerstone of endocrine therapy for estrogen receptor-positive breast cancer; however, its partial estrogen agonist activity in the endometrium predisposes patients to hyperplasia and, in some cases, malignant …

Metabolites are small molecules that are useful for estimating disease risk and elucidating disease biology. Here, we perform two-sample Mendelian randomization to systematically infer the potential causal effects of 1099 plasma metabolites…

BACKGROUND AND AIMS: Due to its association with various diseases, atherogenic index of plasma (AIP) has garnered increasing attention. Exploration of the relationship between AIP and endometriosis risk has not been thorough. This nationwid…

This study investigates the correlation between different ovarian reserves and the oocyte fertilization rate as well as early embryo development in the Changde area. A total of 325 infertile women who underwent in vitro fertilization proced…

Objective: To compare the efficacy of dienogest (DNG) and levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of intrinsic and extrinsic subtypes of adenomyosis. Methods: Totally 232 patients were enrolled in the study w…

Transient receptor potential melastatin M3 (TRPM3) channels have been recognized as a pain transducer in dorsal root ganglion (DRG) neurons in recent years. TRPM3 activation initiates neurogenic inflammation and is required for the developm…

BACKGROUND: An important factor in the pathogenesis of polycystic ovary syndrome (PCOS) is chronic low-grade inflammation. However, the exact pathophysiology of PCOS is currently unknown, which makes clinical diagnosis and the development o…

Rhein is a natural active ingredient in traditional Chinese medicine that has attracted much attention due to its wide range of pharmacological activities. However, its clinical application is limited by low water solubility, poor oral abso…

Objective: To investigate the familial heritability of endometriosis and to compare the clinical characteristics of patients with or without a family history of endometriosis. Methods: From January 2020 to June 2022, 850 patients with endom…

Long noncoding RNAs (lncRNAs), a class of noncoding RNAs with more than 200 bp in length, are produced by pervasive transcription in mammalian genomes and regulate gene expression through various action mechanisms. Accumulating data indicat…

The pathways of gametogenesis encompass elaborate cellular specialization accompanied by precise partitioning of the genome content in order to produce fully matured spermatozoa and oocytes. Transcription factors are an important class of m…

BACKGROUND: The management of ground-glass opacities (GGOs) depends mainly on personal experience. In clinical practice, benign GGOs are not rare in resected specimens, for which operations may be avoided. We retrospectively compared the cl…

BACKGROUND: To investigate the association between serum carbohydrate antigen 125 (CA125) and the presence as well as severity of diabetes retinopathy (DR) in Chinese adult patients with type 2 diabetes. METHODS: A hospital-based cross-sec…

RATIONALE: Uterus-like masses (ULMs) are rare benign lesions that resemble the uterus. PATIENT CONCERNS: Here, we describe the case of a woman with a ULM in the right broad ligament. A 51-year-old woman with a 2-month history of irregular …

Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) plays a vital role in the development of malignant tumors; however, its biological role and underlying mechanism in epithelial ovarian cancer (EOC) remain unclear. In this s…

The lack of efficient tumor progression and chemoresistance indicators leads to high mortality in epithelial ovarian cancer (EOC) patients. Dysregulated miR-520g expression is involved in these processes in hepatic and colorectal cancers. I…

Misregulation of vascular endothelial growth factor A (VEGF‑A) has been implicated in numerous types of ovarian disease, such as polycystic ovarian syndrome, ovarian hyperstimulation syndrome, endometriosis and ovarian cancer. VEGF regulate…

A 67-year-old woman who was presented to the gynecologist with a two-month history of heavy vaginal bleeding, after an excisional biopsy of vulvar mass, was diagnosed with the right colon adenocarcinoma metachronous metastasis to the vulva.…

AIMS: To estimate mortality rates among treated opioid-dependent individuals by cause and in relation to the general population, and to estimate the instantaneous effects of opioid detoxification and maintenance treatment (MMT) on the hazar…
