BACKGROUND: Endometrial thickness (EMT) and blood flow are commonly used indicators of endometrial receptivity. However, the results of single ultrasound examination studies differ. Therefore, we used 3-dimensional (3D) ultrasound to study …

BACKGROUND: Low-grade chronic inflammation may contribute to the pathogenesis of polycystic ovary syndrome (PCOS). Interleukin-15 (IL-15) is a proinflammatory cytokine involved in the development of chronic inflammation leading to obesity-a…

The presence of microbial communities in the reproductive tract has been revealed, and this resident microbiota is involved in the maintenance of health. Intentional modulation via probiotics has been proposed as a possible strategy to enha…

BACKGROUND: Polycystic ovary syndrome (PCOS) is a heterogeneous endocrinological and metabolic disorder which is the common cause of female infertility. The dysmetabolism displayed in it has not been completely ascertained. Metabonomics may…

Robert's uterus is a rare Müllerian malformation first characterized by a French gynecologist Héléne Robert in 1969. It represents an asymmetric division of the uterine cavity. A 45-year-old female patient presented with vaginal bleeding an…

It is well known that the transfer of embryos at the blastocyst stage is superior to the transfer of embryos at the cleavage stage in many respects. However, the rate of blastocyst formation remains low in clinical practice. To reduce the p…

Endometriosis of sciatic nerve is a common gynecological disease. Here we aimed to study the anti-inflammatory and anti-nociceptive role of sulforaphane on sciatic nerve endometriosis. The sciatic nerve endometriosis rat model was construct…

Endometrial cancer (EC) is a common leading cause of cancer-related death in women, which is associated with the increased level of estrogen in the body. Artesunate (ART), an active compound derived from Artemisia annua L., exerted antitumo…

PURPOSE: To provide a reference for clinicians, whether patients with advanced ovarian clear cell carcinoma (OCCC) require chemotherapy (CT) for more than 6 cycles after tumor debulking. PATIENTS AND METHODS: A retrospective review was per…

The aim of the present study was to investigate the role of microRNA‑15a‑5p (miR‑15a‑5p) in pulmonary arterial hypertension (PAH) and elucidate the underlying pro‑apoptotic mechanism. Reverse transcription‑quantitative PCR analysis and gene…

OBJECTIVE: To explore the possible mechanism of protein kinase CK2, which participates in estrogen recruitment of endothelial progenitor cells (EPCs), and its role in the angiogenesis of endometriosis lesions. DESIGN: Laboratory study. SE…

This study investigated the relationship between the pain of sciatic endometriosis and the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway. Adult female Sprague-Dawley rats succ…

This retrospective cohort study aimed to investigate the effect of placental location on birthweight discordance among diamniotic-dichorionic twin pregnancies. Medical records and sonographic reports of 978 diamniotic-dichorionic twin pregn…

This retrospective analysis aimed to clarify the clinical and pathologic features of ovarian clear cell carcinoma (OCCC), and to determine the factors predictive of survival.Data waereextracted from OCCC patients who underwent primary surge…

Endometriosis is one of the most common diseases in women. Inflammation and angiogenesis have been shown to be important in pathogenesis of endometriosis. Crocin is known as an anti-inflammatory, anti- proliferation substance. This study wa…

BACKGROUND: Considered as the precursor lesion of a subset of ovarian clear cell carcinoma (OCCC), the prognostic role of endometriosis in OCCC patients remains controversial. This study aimed to investigate the prognostic role of coexistin…

To investigate the effects and the underlying mechanisms of ginsenoside Rf in a surgically induced rat endometriosis model, endometriosis was constructed through homologous transplantation and the Wistar rats were further randomly classifie…

Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophin growth factors family. Recent studies indicated that the level of BDNF in follicular fluid is a marker for oocyte quality and infertility. Here, we intend to further i…

Endomorphin-1 (EM-1) was reported to have very high affinity and selectivity for μ-opioid receptor (MOR). However, it remained unclear whether EM-1 and MOR were involved in the pathologies of endometriosis resulting in reduced fertility. In…

BACKGROUND & AIMS: Nuclear factor-κB (NF-κB) is activated during early stages of pancreatitis. This transcription factor regulates genes that control many cell activities, including inflammation and survival. There is evidence that activati…

Objective To investigate the Ang-2,the relationship between VEGF and angiogenesis and its expression in ovarian endometriosis(EMs).Methods Selected at between 2007.1-2011.12 collection of ovarian endometriosis patients with surgical specime…

OBJECTIVE: To evaluate the effect of carbon dioxide (CO2) pneumoperitonal pressure on the ultrastructure of implanted endometriotic lesions in a rat model. STUDY DESIGN: An endometriotic model was established in Sprague-Dawley rats with pe…

Objective:To explore the expression of proliferation cell nuclear antigen ki-67 in endometriosis and the effect of proliferative activity of endometrial cells on the occurrence of endometriosis.Methods:Immunohistochemical SP method was used…

Human genome-wide association studies have linked single nucleotide polymorphisms (SNPs) on chromosome 9p21.3 near the INK4/ARF (CDKN2a/b) locus with susceptibility to atherosclerotic vascular disease (ASVD). Although this locus encodes thr…
