BACKGROUND: Adnexal torsion (AT) is a rare emergency complication during pregnancy. Increasing evidence implies that operative laparoscopy for adnexal torsion performed during pregnancy could be safe and feasible. We procured and evaluated …

Helicobacter pylori is a prevalent bacterial pathogen globally, implicated in various gastrointestinal disorders. Current recommended antibiotic therapies for H. pylori infection have been proven to be therapeutically insufficient, with low…

BACKGROUND: Tryptophan 2,3-dioxygenase (TDO2) is the primary enzyme that catabolizes tryptophan to kynurenine. Numerous studies have suggested that TDO2 is involved in inflammation-related diseases. However, its role in osteoarthritis (OA) …

This study is aimed at systematically characterizing the endometriosis-associated genes based on text mining and at annotating the functions, pathways, and networks of endometriosis-associated hub genes. We extracted endometriosis-associate…

OBJECTIVE: Thoracic endometriosis syndrome (TES) is a rare disease in which a functioning endometrial tissue is observed in the pleura, lung, parenchyma, airways, and/or diaphragm. The optimal management of this disease remains a matter of …

Abstract Background: Thoracic endometriosis syndrome (TES) is a rare disease in which a functioning endometrial tissue is observed in the pleura, lung parenchyma, airways, or diaphragm. The optimal management of this disease remains a matte…

To determine the effect of mechanical stretching load and the efficacy of postmenopausal estrogen therapy (ET) on pelvic organ prolapse (POP), vaginal fibroblasts isolated from postmenopausal women with or without POP were subjected to 0.1-…

The present study aimed to identify which patients with adenomyoma would benefit from sparing the uterus and which patients should undergo a hysterectomy to avoid secondary surgery. Patients with pathology-proven adenomyoma admitted to Beij…

BACKGROUND: To evaluate the efficacy and safety of 10 mg and 25 mg mifepristone per day compared with 3.75 mg enantone in treating uterine fibroids. METHODS: This is a Multicenter randomized controlled trial. A total of 501 subjects with s…

NDRG1 (N-myc downstream-regulated gene 1) was previously considered to be a differentiation-related gene. However, many other functions of NDRG1 have since been identified, including proliferation, migration, invasion, and vascularization o…

Ovarian cancer is the most lethal gynecological malignant tumor because of its high recurrence rate. In the present work, in order to find new therapeutic targets, we identified 8480 proteins in thirteen pairs of ovarian cancer tissues and …

BACKGROUND: Occult invasive cervical cancer (OICC) is sometimes incidentally found in surgical specimens after a simple hysterectomy (SH). This study was aimed at identifying a subset of patients with OICC who have a favorable prognosis. Th…

OBJECTIVES: To investigate the prognostic value of endometriosis in patients with stage I ovarian clear cell carcinoma (OCCC). METHODS: The medical records of patients with stage I OCCC who had undergone complete staging surgery followed b…

OBJECTIVES: The present study investigated the clinical implications of pretreatment carbohydrate antigen 125 (CA-125) levels and CA-125 normalization in patients with ovarian clear cell carcinoma (CCC), and it provides useful information f…

Prostaglandin E2 is widely used in obstetrics and is thought to be relatively safe for cervical ripening and induction of labour. Here we present a case in which acute hemoperitoneum was observed after administration of prostaglandin E2 in …

STUDY OBJECTIVE: To evaluate the safety and efficacy of a new crosslinked hyaluronan (NCH) gel in reducing postoperative adhesions. DESIGN: Randomized controlled trial (Canadian Task Force classification I). SETTINGS: Seven departments of…

Mechanical load and postmenopausal hypoestrogen are risk factors for pelvic organ prolapse (POP). In this study, we applied a 0.1-Hz uniaxial cyclic mechanical stretching (CS) with 10% elongation and 10⁻⁸ M 17-β-estradiol to vaginal fibrobl…

The purpose of this study was to determine the risk stratification of deep venous thrombosis (DVT) in patients undergoing gynecological surgery. A retrospective study was conducted with a cohort of 739 consecutive female patients undergoing…

OBJECTIVE: To investigate prognosis of endometriosis and to determined correlative factors of pelvic pain associated with endometriosis after conservative surgery. METHODS: The clinical data in patients with pelvic pain related to endometr…

BACKGROUND: Endometrial cancer (EC) is a common female malignant cancer. The age of incidence has become younger than before. If the diagnosis is during stage I, then the survival rate is about 90%. To date, there are no specific tumor mark…

The aim of this study was to report a case of malignant transformation from residual endometriosis following hysterectomy and bilateral salpingo-oophorectomy in a female patient with a positive family history of ovarian and colon cancer res…

Objective:To evaluate the collection between endometriosis pain and pathological changes through Patient-Assisted Laparoscopy Pain Mapping(PALPM) of mini-laparoscopy.Methods:Prospective study is formed.Patients with endometriosis underwent …
