Colorectal cancer (CRC) is one of the most common malignant tumor types occurring in the digestive system. The incidence of CRC has exhibits yearly increases and the mortality rate among patients with CRC is high. The Wnt/β-catenin signaling pathway, which is associated with carcinogenesis, is abnormally activated in CRC. Most patients with CRC have adenomatous polyposis coli mutations, while half of the remaining patients have β-catenin gene mutations. Therefore, targeting the Wnt/β-catenin signaling pathway for the treatment of CRC is of clinical value. In recent years, with in-depth research on the Wnt/β-catenin signaling pathway, inhibitors have been developed that are able to suppress or hinder the development and progression of CRC. In the present review, the role of the Wnt/β-catenin signaling pathway in CRC is summarized, the research status on Wnt/β-catenin pathway inhibitors is outlined and potential targets for inhibition of this pathway are presented. Contents 1. Introduction 2. Current status of CRC treatments 3. Overview of the Wnt signaling pathway 4. Role of the Wnt/β-catenin signaling pathway in the development and progression of CRC 5.

During interventional procedures, the deficiencies of nonstereoscopic vision increase the difficulty of identifying the anteroposterior direction and pathways of vessels. Therefore, achieving real-time stereoscopic vision during interventional procedures is meaningful. Pairs of X-ray images were captured with identical parameter settings, except for different rotation angles (represented as the α angle). The resulting images at these α angles were used as left-eye and right-eye views and were horizontally merged into single left-right 3D images. Virtual reality (VR) glasses were used for achieving stereo vision. Pairs of X-ray images from four angiographies with different α angles (1.8–3.4°) were merged into left-right 3D images. Observation with VR glasses can produce realistic stereo views of vascular anatomical structure. The results showed that the optimal α angles accepted by the brain for generating stereo vision were within a narrow range (approximately 1.4–4.1°). Subsequent tests showed that during transcatheter arterial chemoembolization, 3D X-ray stereoscopic images provided significantly improved spatial discrimination and convenience for identifying the supply vessels of a liver tumor and its anteroposterior direction compared with plain X-ray images (all P < 0.01). Real-time X-ray stereoscopic vision can be easily achieved via the straightforward method described herein and has the potential to benefit patients during interventional procedures.
