miR-381-3p suppresses breast cancer progression by inhibition of epithelial-mesenchymal transition.

Background: Accumulating evidence indicates that miRNAs are involved in multiple cellular functions and participate in various cancer development and progression, including breast cancer.

Methods: We aimed to investigate the role of miR-381-3p in breast cancer. The expression level of miR-381-3p and EMT transcription factors was examined by quantitative real-time PCR (qRT-PCR).

MicroRNA‑454‑5p promotes breast cancer progression by inducing epithelial‑mesenchymal transition via targeting the FoxJ2/E‑cadherin axis.

MicroRNAs are important for the regulation of multiple cellular functions and are involved in the initiation and progression of various types of cancer, including breast cancer. Although microRNA (miR)‑454‑3p is reported to function as an oncogene in several types of human cancer, the role of miR‑454‑5p in breast cancer remains unknown. The present study demonstrated that miR‑454‑5p was upregulated in breast cancer and was associated with a poor prognosis in patients with breast cancer.

Robust image hashing via visual attention model and ring partition.

Robustness is an important property of image hashing. Most of the existing hashing algorithms do not reach good robustness against large-angle rotation. Aiming at this problem, we jointly exploit visual attention model and ring partition to design a novel image hashing, which can make good rotation robustness.

Lugol chromoendoscopic screening for esophageal dysplasia/early squamous cell carcinoma in patients with esophageal symptoms in low-risk region in China.

Detection of esophageal dysplasia/early esophageal squamous cell carcinoma (ESCC) is essential for improving 5-year survival. The aim of this prospective study was to evaluate whether Lugol chromoendoscopy improves the detection of esophageal dysplasia/early ESCC in patients with esophageal symptoms in a low-incidence region in China. Eligible patients were randomly assigned into two groups who received routine endoscopy or Lugol chromoendoscopy.

Aortoesophageal fistula: a case misdiagnosed as esophageal polyp.

Aortoesophageal fistula (AEF) is a rare and fatal disorder. It is also a life-threatening cause of massive upper gastrointestinal hemorrhage. Thoracic aortic aneurysm is the most common cause of AEF.
