Nomogram based on the O-RADS for predicting the malignancy risk of adnexal masses with complex ultrasound morphology.

Objective: The accurate preoperative differentiation of benign and malignant adnexal masses, especially those with complex ultrasound morphology, remains a great challenge for junior sonographers. The purpose of this study was to develop and validate a nomogram based on the Ovarian-Adnexal Reporting and Data System (O-RADS) for predicting the malignancy risk of adnexal masses with complex ultrasound morphology.

Methods: A total of 243 patients with data on adnexal masses with complex ultrasound morphology from January 2019 to December 2020 were selected to establish the training cohort, while 106 patients with data from January 2021 to December 2021 served as the validation cohort.

The Performance of Transvaginal Two-Dimensional Fundamental Sonosalpingography Combined with Saline Infusion Pelvic Sonosalpingography for Assessing Fimbrial Part's Morphology and Function of the Fallopian Tubes.

Objectives: The purpose of this study was to evaluate the diagnostic efficacy of transvaginal two-dimensional fundamental sonosalpingography (2D-FS) combined with saline infusion pelvic sonosalpingography (SIPS) for assessing fimbrial part's morphology and function of the fallopian tubes.

Methods: One hundred and sixty-nine cases underwent 2D-FS combined with SIPS. Among them, 18 cases received laparoscopy and dye test (LDT) within 3 months after the examination and the results were regarded as reference standard.

Role of laparoscopy as a minimally invasive procedure in treatment of ruptured uterine scar during second-trimester induction of abortion.

Uterine rupture is an uncommon complication following termination of pregnancy and is usually accompanied by severe lower abdominal pain and shock caused by intra-abdominal hemorrhage. Laparotomy should be carried out promptly in order to repair the uterus or even to resect the uterus. Here we present a case of uterine rupture of a scarred uterus, which occurred during a second-trimester induced abortion.

Silencing of periostin inhibits nicotine-mediated tumor cell growth and epithelial-mesenchymal transition in lung cancer cells.

Nicotine has been found to induce the proliferation of lung cancer cells through tumor invasion and to confer resistance to apoptosis. Periostin is abnormally highly expressed in lung cancer and is correlated with angiogenesis, invasion and metastasis. Here, we investigated the roles of periostin in the lung cancer cell proliferation, drug resistance, invasion and epithelial-mesenchymal transition (EMT) induced by nicotine.
