Expression Profile of Hydroxysteroid Dehydrogenase-like 2 in Polychaete in Response to BPA.

Hydroxysteroid dehydrogenases (HSDs) play an important role in the metabolism of steroids and xenobiotics. However, the function of HSDs in invertebrates is unclear. In this study, we cloned the hydroxysteroid dehydrogenase-like 2 (HSDL2) gene in , which is 1652 bp in length, encoding 400 amino acids.

Value on the diagnosis of axillary lymph node metastasis in breast cancer by color Doppler ultrasound combined with computed tomography.

Purpose: To explore the clinical application value of color Doppler ultrasound combined with computed tomography (CT) in the diagnosis of axillary lymph node metastasis (ALNM) in breast cancer.

Methods: From January 2016 to June 2018, 189 breast cancer patients who underwent radical mastectomy in our hospital were included and retrospectively analyzed. All patients had preoperative color Doppler ultrasound and CT examination of mammary gland and axillary lymph nodes, with pathological diagnosis as the gold standard.
