BACKGROUND: Endometriosis (EM) affects 10% women of reproductive age and alters fertility. Its management is still debated notably the timing of surgery and ART in infertility. Kallistatin (KS) is an endogenous protein that regulates differ…

Abstract Background: Endometriosis (EM) affects 10% of women in reproductive age and alters fertility. Its management is still debated notably the timing of surgery and ART in infertility. Kallistatin (KS) is an endogenous protein that regu…

Endometriosis (EM) is a disease that involves active endometrial cell invasion and migration which is an important reason for infertility. Anoikis resistance is the most important prerequisite for EM, but the molecular mechanism is not yet …

BACKGROUND: Endometriosis of the uterine body can be manifested as diffuse solid lesions or cystic lesions. The former is common, while the latter is rare, especially for cystic adenomyosis larger than 5 cm. CASE PRESENTATION: A 30-year-ol…

BACKGROUND: The prognosis of recurrent low-grade endometrial stromal sarcoma (LGESS) is little known. This study was to investigate the survival outcomes of a cohort of patients with recurrent LGESS. METHODS: Patients with primary LGESS di…

BACKGROUND: Lung cancer is the tumor with the highest morbidity and mortality, and has become a global public health problem. The incidence of lung cancer in men has declined in some countries and regions, while the incidence of lung cancer…

OBJECTIVE: To investigate the significance of perioperative levonorgestrel-releasing intrauterine system (LNG-IUS) and/or gonadotropin-releasing hormone agonists (GnRHa) as adjuvant therapy in preventing recurrences or progression of diseas…

PURPOSE: Exosomes are the effective delivery system for biological compounds, including circular RNAs. In this research, we aimed to explore the role of circular RNA hsa_circRNA_0002130 in osimertinib-resistant non-small cell lung cancer (N…

BACKGROUND: Pelvic organ prolapse (POP) affects around 15% of postmenopausal women in China. Although it has been widely accepted that genetic variants could confer risk for POP, the genetic susceptibility variants remain largely unknown. P…

BACKGROUND: Multiple pregnancies are associated with significant complications and health risks for both mothers and infants. Single blastocyst transfer (SBT) is a logical and effective measure to reduce the incidence of multiple pregnancy …

Little is known about the epidemiological and clinicopathological characteristics of endometrial endometrioid carcinoma (EEC) coexisting with or arising in adenomyosis (EEC-A or EEC-AIA) due to their rarity. This study compared EEC-A and EE…

The aim of current study was to apply the methylated DNA immunoprecipitation (MeDIP)-Chip method to investigate dynamic changes in CpG island methylation in human sperm, oocytes and various developmental stages of preimplantation embryos. S…

Adenomyosis is frequently observed in premenopausal women, and oral dienogest is the recommended treatment to target the underlying pathology and improve the symptoms. This retrospective study investigated the association of Lewis (b) antig…

BACKGROUND: We report an extremely rare case of vaginal clear cell carcinoma, which originated from the malignant transformation of vaginal adenosis without prenatal diethylstilbestrol (DES) exposure. CASE PRESENTATION: In this case, the p…

Progesterone elevation (PE) on the day of hCG trigger is associated with decreased pregnancy outcome in fresh cycles. Evidence for this comes from overall patient estimates that mostly ignore different ovarian responses. To compare the impa…

INTRODUCTION: Little is known about the prevalence and prognosis of synchronous endometrial and ovarian carcinomas. This report explores the survival outcomes of synchronous stage IA endometrioid endometrial and stage IA ovarian carcinomas …

OBJECTIVE: To determine the long-term effects of using the levonorgestrel-releasing intrauterine system (LNG-IUS) to treat symptomatic adenomyosis. METHOD: A prospective longitudinal study was conducted among 1100 women who received the LN…

Objective To investigate the relationship of endometrial polyps (EPs) and endometriosis (EMS), and evaluate the predictive value of EMS fertility index (EFI) for women’s fertility with EMS combined with EPs. Methods A total of 248 in…

Cases of squamous cell carcinoma (SCC) arising from ovarian endometriosis have been rarely reported. Most of the patients show a poor prognosis and present with a diminished survival time. We present a SCC case arising from endometriosis, a…

OBJECTIVE: To study the effect of interleukin-1β (IL-1β) on the expressions activin A, follistatin, and cripto in cultured human endometrial stromal cells (HESCs) form patients with endometriosis. METHODS: Cultured HESCs were stimulated wi…

OBJECTIVE: To detect aberrant methylation in the promoter region of fetal endometriosis susceptibility gene homeobox-10 (HOXA10) in women with and without folic acid supplementation and explore the effect of folic acid in optimizing intraut…

Objective To detect the endometriosis susceptibility gene of HOXA10 promoter region aberrant methylation in pregnant women with endometriosis and normal pregnant women,and to analyze the family heredity of endometriosis.Methods Specimens we…

Objective:To evaluate effect of Shuqi Dingtong Formula on Qi stagnancy and blood stasis syndrome in Chronic Pelvic Inflammatory Disease(CPID).Methods:Totally 68 patients were randomized into treatment group and control group.The treatment g…

OBJECTIVE: To investigate strategies of diagnosis and treatment of ureter endometriosis. METHODS: From 1983 to 2010, the cases registered in Peking Union Medical College Hospital and confirmed as ureter endometriosis by surgery were enroll…

OBJECTIVE: To explore the hospital expenses and hospital stay of surgical management for endometriosis and adenomyosis. METHODS: The average hospital expenses and average hospital stay were compared for a total of 12003 patients of endomet…
