Background: The breast imaging-reporting and data system (BI-RADS) grading has a great advantage in diagnosing breast diseases, but with some limitations.

Aims: The study analyzed the value of ultrasound-guided core needle biopsy (CNB) in diagnosing BI-RADS grades 3, 4, and 5 breast cancer.

Methods: Breast cancer patients at BI-RADS grades 3 to 5 received breast ultrasonography, ultrasound-guided CNB and immunohistochemical examination.

This study was aimed at assessing the effects of urokinase (UK) in combination with ultrasound and microbubbles in in vitro and in vivo thrombolytic therapy for the treatment of deep vein thrombosis (DVT). Thrombi with formation times of 1, 3, 7, 14 and 21 d were used for thrombolysis. Forty-five adult mongrel dogs were used to evaluate thrombosis in vivo.

MicroRNAs (miRNAs) have recently been identified as a novel class of gene regulators, playing an important role in various malignancies. In the present study, we investigated the role of miRNA-130b in the development of drug resistance in ovarian cancer cells. The human ovarian carcinoma cell line A2780 and paclitaxel-resistant A2780/Taxol cells were exposed to the chemotherapeutic agent cisplatin or paclitaxel in the presence or absence of transfected miR-130b.

Fibroadenomatoid hyperplasia of the breast (FAHB) is a rare benign breast lesion and its clinical features are similar to fibroadenoma and fibrocystic changes. FAHB has been previously termed sclerosing lobular hyperplasia, fibroadenomatosis, fibroadenomatoid change, or fibroadenomatoid mastopathy. Typically, FAHB is derived from stroma and epithelia.

Objective: To assess the interobserver reliability of antral follicle counts (AFC) using Real-time two-dimensional (2D) ultrasound and three-dimensional (3D) ultrasound.

Methods: Two observers conducted transvaginal ultrasound examinations in 51 subfertile women in the early follicular phase of the menstrual cycle. Antral follicles were counted using Real-time 2D ultrasound and the time taken was recorded.

Juvenile polyps are a rare form of gastrointestinal polyps and are generally diagnosed by colonoscopy or barium enema. In this article, we describe the case of a 3-year-old girl with a large juvenile polyp that was diagnosed by abdominal ultrasound. Ultrasound examination is necessary for children who pass dark red bloody stools either with or without abdominal pain.

The aims of this study were to assess the effects and potential mechanisms of parthenolide on the expression of vascular endothelial growth factor (VEGF), interleukin 8 (IL-8) and matrix metalloproteinase 9 (MMP-9) in human breast cancer cell line MDA-MB-231. After incubation with different concentrations of parthenolide for 24 h, MDA-MB-231 cells were collected, and the expressions of VEGF, IL-8 and MMP-9 were measured by real-time PCR and Western blot. The secretions of VEGF, IL-8 and MMP-9 in culture supernatant of MDA-MB-231 cells were then measured with ELISA assays.

Background: Parthenolide has been tested for anti-tumor activities, such as anti-proliferation and pro-apoptosis in recent studies. However, little is known about its role in the process of tumor angiogenesis. This study aims to investigate the effects and potential mechanisms of parthenolide on the proliferation, migration and lumen formation capacity of human umbilical vein endothelial cells.
