Endometriosis is a disease that involves dysfunction of mitochondria, imbalance of proliferation, and apoptosis. Coiled-coil-helix-coiled-coil-helix domain containing 2 (CHCHD2) is a major mitochondrial protein which could regulate the mito…

ObjectiveEthiodized poppy seed oil for hysterosalpingography (HSG) is reported to display some therapeutic effect on infertility, but big a sample-size study under real clinical settings is still lacking to verify the speculation. Thus, thi…

The vagina contains at least a billion microbial cells, dominated by lactobacilli. Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age, as well as cervical, fec…

ObjectiveThis study aimed to better understand the psychological experiences of inpatients with acute pancreatitis (AP).DesignWe used a qualitative descriptive study design to capture patients with AP's thoughts, feelings and behavioural re…

BackgroundAlthough oocyte quality is the dominant factor determining embryo quality, few studies have been conducted to evaluate embryo quality based on the metabolites related to the oocyte. With quantification of the follicular fluid (FF)…

This is a retrospective cohort study included 1021 patients underwent a flexible GnRH antagonist IVF protocol from January 2017 to December 2017 to explore the effect of a premature rise in luteinizing hormone (LH) level on the cumulative l…

"Dual triggering" for final oocyte maturation using a combination of a gonadotropin-releasing hormone agonist (GnRHa) and human chorionic gonadotropin (hCG) can improve clinical outcomes in high responders during in vitro fertilization-intr…

BACKGROUND: Research into the pathogenesis of endometriosis (EMs) would substantially promote its effective treatment and early diagnosis. However, the aetiology of EMs is poorly understood and controversial despite the progress in EMs rese…

BackgroundCold, an environmental factor, induces many reproductive diseases. It is known that endothelin (ET) is a potent vasoconstrictor, and cold stress can increase the expression of ET and its receptors. The cold stress rat model was de…

Little is known about the genetic alterations characteristic of ovarian clear cell carcinoma (OCCC). Our aim was to identify targetable genomic alterations in this type of cancer. Forty-two OCCC formalin-fixed, paraffin-embedded (FFPE) tiss…

Ovarian cancer (OC) is most common type of gynecologic cancer and is frequently lethal. It is important to determine the pathologic mechanisms underlying OC. ZNF93 is a member of the zinc finger protein family. Abnormal expression of ZNF93 …

OBJECTIVE: To explore the effects of GnRHa on adenomyosis by transvaginal elastography. METHODS: A prospective observational study included patients who were diagnosed as adenomyosis by conventional transvaginal ultrasound and infertility.…

ObjectiveTo explore whether operation can change the elasticity of levator ani in deep infiltrating endometriosis (DIE) with operation and pharmacotherapy using transperineal elastography.MethodsTotal thirty-four patients who were diagnosed…

Triterpenoids are distributed widely in higher plants and are of interest because of their structural diversity and broad range of bioactivities. In particular, there is a very large literature on the propensity of a variety of triterpenoid…

Intrauterine adhesion (IUA) is one of the most common diseases of the reproductive system. Due to the high postoperative recurrence rate of IUA, it is crucial to identify the possible causes of pathogenesis and recurrence of this disease. I…

PurposeTo assess the elasticity of the pelvic floor muscle (PFM) affected by deep infiltrating endometriosis (DIE) with transperineal elastography.MethodsThis prospective observational study included 88 patients who were diagnosed with DIE,…

PurposePolydatin, a stilbenoid glucoside of a resveratrol derivative, has many biological functions, including antitumor effects. However, the antitumor effects of polydatin in renal cell carcinoma (RCC) have not been investigated.Materials…

To test the hypothesis that the lesional stiffness as measured by transvaginal elastosonography (TVESG) correlates with the extent of fibrosis in adenomyotic (AM) lesions, and thus TVESG can be used to diagnose AM, we conducted 2 studies. T…

This study aims to determine whether clinical evaluation of improved MyoSure hysteroscopic tissue removal system can remove type II submucosal myomas with safety and high success rate of the first operation.Fifty-three patients with type II…

Background. Dysmenorrhea is a common problem for which acupuncture provides effective analgesia. Although acupoint selection affects the effectiveness of acupuncture, the basic rules of acupoint selection are little understood. This study a…

BackgroundThe aim of this study was to evaluate the effect of dexamethasone added to local lidocaine infiltration on incidence and severity of backache after combined spinal-epidural anesthesia for gynecological surgery.Material and methods…

Parovarian cysts are common disorders which constitute 10-20% of adnexal masses in pathologically verified series. Most of these cysts are benign, and borderline parovarian tumors are rare and documented only as case reports in the literatu…

OBJECTIVES: The purpose of this study was to evaluate the clinical value of strain elastography for detection of the lesion extent of large-scar endometriosis and compare it to conventional sonography and magnetic resonance imaging (MRI). M…

BackgroundRhesus macaques are the most widely utilized nonhuman primate model in biomedical research. Previous efforts have validated fewer than 900 single nucleotide polymorphisms (SNPs) in this species, which limits opportunities for gene…

ObjectivesTo detect specific mitochondrial proteins in eutopic endometrial samples from women with and without endometriosis and to build diagnostic models.DesignEutopic endometrial samples from women with endometriosis (excluding adenomyos…
