Circular RNAs (circRNAs) are involved in the pathogenesis of many diseases, although their expression pattern and role in endometriosis remains unknown. Therefore, here, we profiled the expression patterns of circRNAs in ovarian ectopic and…

OBJECTIVE: To investigate the expression of potassium channels and the influence of estrogen and progesterone on the cultured uterine smooth muscle cells (USMC) of adenomyosis in vitro. METHODS: There were 22 cases of adenomyosis hysterect…

The malignant transformation of abdominal wall endometriosis is a rare event and poorly understood. Less than 30 cases have been reported in the literature. Most of the reported cases have a solitary tumor in the abdominal scar. A few cases…

Endometriosis (EM) impacts the healthcare and the quality of life for women of reproductive age. However, there is no reliable noninvasive diagnosis method for either animal study or clinical use. In this work, a novel imaging method, photo…

This paper demonstrates an in vitro model to simulate the microenvironment of endometriosis. We used microfluidic channels with cover slips to pattern and release endometrial stromal cells (ESCs) and human peritoneal mesothelial cells (HPMC…

STUDY QUESTION: Can plasma microRNAs be used as a non-invasive diagnostic test for the detection of endometriosis? SUMMARY ANSWER: Plasma miR-17-5p, miR-20a and miR-22 are down-regulated in women with endometriosis compared with those with…

Endometriosis, with a prevalence rate ranging from 6% to 10%, is the major contributor to pelvic pain and subfertility, and considerably reduces the quality of life in affected women. However, the pathogenesis of this disease remains largel…

OBJECTIVE: To evaluate follicle loss and its associated factors during laparoscopic cystectomy for ovarian endometrioma. METHOD: Between October 2008 and December 2009, 140 patients with ovarian cysts undergoing laparoscopic cystectomy at …

OBJECTIVE: To analyze the clinical presentation of perineal endometriosis and evaluate its treatment. METHODS: Clinical data were analyzed from the records of 36 patients with perineal endometriosis who were operated on between 1983 and 20…

Angiogenesis and vascular permeability occur following endothelium activation by vascular endothelial growth factor (VEGF). Downstream mechanisms that define these vascular responses remain unknown. H-Ras activation has been associated with…

Malignant change of endometriosis in a cesarean scar (CS) is rare. We report a case of carcinosarcoma arising from atypical endometriosis in a CS scar, which was successfully treated with complete excision of the lesion and repair of the ab…

OBJECTIVE: To investigate the clinical characteristics, treatment, and factors of recurrence of abdominal wall endometriomas (AWE). METHOD: Sixty-four cases of AWE diagnosed at Peking Union Medical College Hospital (PUMCH) from 1983 to 200…

OBJECTIVE: To study the characteristics, diagnosis and treatment of endometriosis in adolescent patients. METHOD: Six cases of adolescent endometriosis in our hospital were reviewed retrospectively. RESULT: Endometriosis is the most commo…

OBJECTIVE: To report the diagnosis and treatment of 11 cases with perineal endometriosis (PE). METHODS: Eleven patients with PE treated in our department from 1983 - 2000 years were analyzed retrospectively and were followed for 0.5 - 7.0 …

OBJECTIVE: To analyze the clinical features of congenital vaginal atresia (CVA) with normal uterine corpus and investigate the relationship between the subtypes and management. METHODS: Sixteen cases, partical atresia (type I) 10 and compl…

OBJECTIVE: To investigate the serum levels of ICAM-1 and its relationship to the extent of the disease. METHODS: Serum sICAM-1 levels of 21 women with endometriosis were measured with a specific enzyme-linked immunosorbent assay, and 21 wo…
