The aim of the present study was to examine the effects of the human chorionic gonadotropin (hCG) dose on the pulsatility indices (PI) of the intraovarian artery on the day of follicle aspiration and the oocyte quality, intrafollicular oxid…

BACKGROUND: To evaluate the clinical significance of serum CA-125 and CA19-9 in women with spontaneous ruptured ovarian endometriomas. METHODS: From January 2006 to April 2015, a total of 1653 women were diagnosed with ovarian endometrioma…

DNA methylation is clinically relevant to important tumorigenic mechanisms. This study evaluated the methylation status of candidate genes in cervical neoplasia and determined their diagnostic performance in clinical practice. Cervical canc…

BackgroundDecidualization is a prerequisite for successful implantation and the establishment of pregnancy. Krüppel-like factor 12 (KLF12) is a negative regulator of endometrial decidualization in vitro. We investigated whether KLF12 was as…

BACKGROUND: The transformation of endometrium into decidua is essential for normal implantation of the blastocyst. However, the post-transcriptional regulation and the miRNAs involved in decidualization remain poorly understood. Here, we ex…

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links…

PURPOSE: The phosphoinositol-3 kinase (PI3K) pathway is frequently dysregulated in endometrial cancer (EC). Hormonal manipulation leads to response in some patients with EC, but resistance derived from PI3K pathway activation has been docum…

BackgroundProgesterone is essential for the proliferation and differentiation of mammary gland epithelium. Studies of breast cancer cells have demonstrated a biphasic progesterone response consisting of an initial proliferative burst follow…

BACKGROUND: Matrix metalloproteinase 2 (MMP-2) has been reported to be an important regulator of cell migration and invasion through degradation of the extracellular matrix (ECM) in many diseases, such as cancer and endometriosis. Here, we …

Tubal diverticula is a rare disease, and the literature includes only a few reports of this condition. We tentatively summarized 13 cases to investigate the clinical characteristics, diagnosis, and treatment of tubal diverticula. The clinic…

The aim of this study was to explore the effect of a traditional Chinese medicine (Xiaochaihu Tang, XCHT) on the expression of matrix metalloproteinase-2 (MMP-2) and MMP-9 in rats with endometriosis (EMs). A total of 48 specific-pathogen-fr…

BACKGROUND: Endometriosis is a common disease. The most widely used staging system of endometriosis is the revised American Fertility Society classification (r-AFS classification) which has limited predictive ability for pregnancy after sur…

BackgroundHigh circulating luteinizing hormone (LH) level is a typical biochemical feature of polycystic ovary syndrome (PCOS) whose pathophysiology is still unclear. Certain mutations of LH and LH receptor (LHR) may lead to changes in bioa…

ObjectiveAppropriate dosage of the long-acting depot gonadotrophin releasing hormone (GnRH) agonist has not been determined in long protocol for IVF, and one-third-dose depot triptorelin was compared with half-dose in a luteal long protocol…

Danazol, a derivative of testosterone, is useful for treatment of endometriosis as well as pretreatment for in vitro fertilization and embryo transfer, although its mechanisms of action are unclear. The aim of this study was to investigate …

BackgroundHepatic angiomyolipoma (HAML) is a rare liver tumor. This paper summarized the clinical, radiological and pathological features of HAML.MethodsSeventeen cases of HAML were analyzed retrospectively. All patients were subjected to s…

Danazol, a modified testosterone, has been used to treat endometriosis and pretreatment before in vitro fertilization and embryo transfer, although its reproductive mechanisms remain unclear. We investigated the effect of danazol on alloimm…

Sister Mary Joseph's nodule (SMJN) refers to a metastatic tumor of the umbilicus. It is a rare entity which arises from a malignancy in the intra-abdominal cavity. We herein describe a patient who presented with SMJN as his first sign of pa…

BackgroundTo study the effect of endometrial thickness and pattern measured using ultrasound upon pregnancy outcomes in patients undergoing IVF-ET.MethodOne thousand nine hundred thirty-three women undergoing IVF treatment participated in t…

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 evaluate the diagnostic values of four risk of malignancy indices (RMI) for malignant adnexal masses. METHODS: The data of 223 women with adnexal masses admitted to the Department of Obstetrics and Gynecology of Peking Union …

OBJECTIVE: The objective of this study was to evaluate the presence of fractalkine in the ascites and the association between fractalkine levels in the ascites and endometriosis. METHODS: Peritoneal fluids and peripheral blood samples were …

ObjectiveTo evaluate spiral CT urography (SCTU) and CT virtual endoscopy (CTVE) in detecting urologic diseases.MethodsSCTU was performed in 46 patients with urological diseases including renal neoplasms (2), paropelvic cysts (2), ureteral c…
