Luteolin inhibits angiogenesis and enhances radiotherapy sensitivity of laryngeal cancer via downregulating Integrin β1.

Aim: To demonstrate the role and mechanism of luteolin in radio-sensitization and angiogenesis of laryngeal cancer.

Methods: Firstly, we analyzed the cytotoxicity of Luteolin and radiation sensitive cytotoxicity through CCK8, and selected subsequent radiation doses and Luteolin concentrations. Next, we further analyzed the effects of Luteolin on radiation sensitivity and neovascularization of laryngeal cancer, and conducted CCK8, plate cloning, and angiogenesis experiments, respectively.

Intelligent Segmentation Algorithm for Diagnosis of Meniere's Disease in the Inner Auditory Canal Using MRI Images with Three-Dimensional Level Set.

This paper aimed to explore segmentation effects of the magnetic resonance imaging (MRI) images of the inner auditory canal of patients with Meniere's disease under the intelligent segmentation method of the inner ear based on three-dimensional (3D) level set (IS3DLS). The statistical shape model and the level set segmentation algorithm were combined to propose the IS3DLS. First, the shape training samples of the inner ear model were determined, and the results were manually segmented to further obtain region of interest (ROI) of the inner ear.

Matrix metalloproteinase-1 (MMP1) polymorphism is associated with lowered risk of nasopharyngeal carcinoma in Asian population.

Data on the association between -1607 1G > 2G polymorphism in the promoter region of matrix metalloproteinase-1 (MMP1) and nasopharyngeal carcinoma (NPC) are conflicting. The aim of this study was to confirm whether this polymorphism was a causative factor of NPC. We searched PubMed, Embase, and China National Knowledge Infrastructure (CNKI) for studies on the present topic.
