OBJECTIVES: In vitro studies showed that lipophilic statins inhibit cell growth, adhesion, and invasion and induce apoptosis in cancer cell lines. In uterine cervical cancer, several important factors including age, stage, anemia, lymphovascular invasion, lymph node metastases, and parametrial spread were known to significantly predict survival. We investigated whether statin therapy as a prognostic factor would significantly predict survival in cervical cancer. METHODS: Patients with stages IB to IV cervical cancer who received radical hysterectomy and/or para-aortic lymph node dissection were included...

The current commonly used treatments for cesarean scar pregnancy (CSP) include multiple treatments such as medication, uterine artery embolization, curettage and surgery, and their combinations. However, every treatment option has risks of excessive hemorrhage from uterus. In this study, we retrospectively analyzed the risk factors for intraoperative hemorrhage of different treatments for CSP patients, with the hope to provide the guidance for CSP treatment.Fifty-eight cases of CSP patients who were treated with curettage after medication, curettage after uterine artery embolization, or surgery were retrospectively analyzed and compared for the clinical efficacy, length of hospital stay, and hemorrhage rate...

BACKGROUND: Adenomyosis is a gynecological disorder with symptoms most presenting as dysmenorrhea and heavy menstrual bleeding. However, the presence of lower urinary tract symptoms (LUTS) among women with adenomyosis remains unclear. This study was designed to determine the prevalence of LUTS and factors related to the severity of these symptoms in this population. METHODS: From July 2016 to November 2016, a total of 298 untreated symptomatic adenomyosis patients and 280 age-matched controls were enrolled...

To explore the impact of high-intensity focused ultrasound (HIFU) ablation of uterine fibroids in nulliparous women on subsequent pregnancy and delivery. A retrospective analysis was conducted of nulliparous women who received HIFU treatment at Chongqing Medical University, Chongqing,China, from January 1, 2010, to January 1, 2015. A total of 189 cases were enrolled, the median follow-up time was three years. Among them,there were 131 cases pregnancy with a total of 133 times,the pregnancy rate was 69.3% (131/189),and the spontaneous conception rate was 95...

Embryonic diapause is a common reproductive strategy amongst mammals, requiring an intimate cross-talk between the endometrium and the blastocyst. To date, the precise molecular signals responsible are unknown in the mouse or any other mammal. Previous studies in the mink implicate polyamines as major regulators of the control of diapause. In the mouse, inhibiting the rate-limiting enzyme of polyamine synthesis, ornithine decarboxylase (ODC1) during early pregnancy largely prevents implantation, but the fate of the non-implanted embryos is unknown...

It is widely hypothesized that menstrual pain is triggered by prostaglandin synthesis that evokes high-pressure uterine contractions and ischemia. However, the effects of molecules implicated in menstrual pain on uterine contractility, perfusion, and oxygenation in vivo have been rarely demonstrated. Studies in women that do not respond to nonsteroidal anti-inflammatory drugs (NSAIDs) have reported elevated levels of platelet-activating factor (PAF). To establish in vivo evidence of PAF's capability to impair uterine homeostasis and to elicit visceral pain, we examined the effects of the PAF receptor agonist (carbamyl PAF [CPAF]) in comparison to other molecules hypothesized to play a role in uterine pain in mice...

Toxoplasmosis can cause abortion in pregnant humans and other animals; however, the mechanism of abortion remains unknown. C-C chemokine receptor type 5 (CCR5) is essential for host defense in T. gondii infection. To investigate the relationship between CCR5 and abortion in toxoplasmosis, we inoculated wild-type and CCR5-deficient (CCR5(-/-)) mice with T. gondii tachyzoites intraperitoneally on day 3 of pregnancy (E3). The pregnancy rate decreased as pregnancy progressed in the infected wild-type mice. Histopathologically, no inflammatory lesions were observed in the fetoplacental tissues...

Porcine conceptuses secrete pregnancy-recognition signals (estrogens, including estradiol-17β) that inhibit luteolysis, thereby prolonging progesterone production by corpora lutea. The supportive mechanism by which the conceptus also inhibits luteolysis is by shifting endometrial prostaglandin (PG) synthesis to luteoprotective PGE2. Progesterone stimulates endometrial production of factors that are essential for conceptus development. Priming the uterus by progesterone and loss of progesterone receptors from the uterine epithelium by D1ay 10-12 after estrus are key for achieving endometrial receptivity for implantation...

Preeclampsia is manifested as maternal hypertension-in-pregnancy (HTN-Preg) and fetal growth restriction. Placental ischemia could be an initiating event; however, the molecular targets and intermediary mechanisms are unclear. We tested the hypothesis that placental ischemia could target vascular and uteroplacental matrix metalloproteinases (MMPs) through cytokines-mediated mechanism. MMP levels and distribution were measured in aorta, uterus and placenta of normal pregnant rats (Preg), and pregnant rats with reduced uterine perfusion pressure (RUPP)...

The endometrial layer comprises luminal and glandular epithelia that both develop from the same simple layer of fetal uterine epithelium. Mechanisms of uterine epithelial progenitor self-renewal and differentiation are unclear. This study aims to systematically analyze the molecular and cellular mechanisms of uterine epithelial development by single-cell analysis. An integrated set of single-cell transcriptomic data of uterine epithelial progenitors and their differentiated progenies is provided. Additionally the unique molecular signatures of these cells, characterized by sequential upregulation of specific epigenetic and metabolic activities, and activation of unique signaling pathways and transcription factors, were also investigated...

PURPOSE: Unaffected women who carry BRCA1 or BRCA2 mutations face difficult choices about reducing their breast cancer risk. Understanding their treatment preferences could help us improve patient counseling and inform drug trials. The objective was to explore preferences for various risk-reducing options among women with germline BRCA1/2 mutations using a discrete-choice experiment survey and to compare expressed preferences with actual behaviors. METHODS: A discrete-choice experiment survey was designed wherein women choose between hypothetical treatments to reduce breast cancer risk...

The aim of this study was to determine how 60-min ischemia changes the expression of hypoxia inducible factor 1α (HIF-1α) and superoxide dismutases (SOD)-1 and -2 in selected regions of porcine uterine horns. The results showed that 60-min ischemia of the porcine uterus conducted at the mid-secretory estrous phase caused decreased HIF-1α and increased SOD-2 gene expression. Higher expression of SOD-2 suggests that this enzyme may play an important role in the suppression of HIF-1α accumulation in an ischemic endometrium...

INTRODUCTION: Placental explant culture is an important model for studying placental development and functions. We investigated the differences in placental gene expression in response to tissue culture, atmospheric and physiologic oxygen concentrations. METHODS: Placental explants were collected from normal term (38-39 weeks of gestation) placentae with no previous uterine contractile activity. Placental transcriptomic expressions were evaluated with GeneChip(®) Human Genome U133 Plus 2...

INTRODUCTION: Epidural analgesia has been considered a risk factor for labor dystocia at trial of labor after cesarean (TOLAC) and uterine rupture. We evaluated the association between exposure to epidural during TOLAC and mode of delivery and maternal-neonatal outcomes. MATERIALS AND METHODS: A single center retrospective study of women that consented to TOLAC within a strict protocol between 2006 and 2013. Epidural "users" were compared to "non-users". Primary outcome was the mode of delivery: repeat in-labor cesarean or vaginal birth after cesarean (VBAC)...

BACKGROUND/AIM: This study aimed to evaluate the role of adjuvant therapy for stage I uterine leiomyosarcoma (LMS). MATERIALS AND METHODS: Clinicopathological data of cases of stage I uterine LMS from 1998 to 2015 were retrieved from the computerized database of Hacettepe University Hospital. The Kaplan-Meier method was used to estimate survival and progression-free survival, and survival differences were analyzed by log-rank test. Cox regression analysis was performed to account for the potential influence of confounding factors...
