This article discusses the new needs and development direction of medical testing technology under the hierarchical diagnosis and treatment system in China, outlines the principles and advantages of new medical testing technology based on smartphones, and briefly describes the development status and research results of smartphone testing technology in specific medical testing directions such as immune analysis, nucleic acid analysis, biochemical analysis and cell morphology analysis. In addition, the article also discusses the current problems of smartphone medical testing technology, such as poor compatibility with different models of smartphones, few detection indicators, low automation, lack of clinical verification. Finally, a prospect is made for the possible future development direction of smartphone medical examination technology, aiming to provide a certain reference for the promotion and more reasonable application of smartphone medical examination technology.
Polyurethane materials have good biocompatibility, blood compatibility, mechanical properties, fatigue resistance and processability, and have always been highly valued as medical materials. Polyurethane fibers prepared by electrostatic spinning technology can better mimic the structure of natural extracellular matrices (ECMs), and seed cells can adhere and proliferate better to meet the requirements of tissue repair and reconstruction. The purpose of this review is to present the research progress of electrostatically spun polyurethane fibers in bone tissue engineering, skin tissue engineering, neural tissue engineering, vascular tissue engineering and cardiac tissue engineering, so that researchers can understand the practical applications of electrostatically spun polyurethane fibers in tissue engineering and regenerative medicine.
