Cartilage with limited self-repairing ability is a kind of tissue with relatively hypocellular structure, low nerve distribution and vascular nutrient. Cartilage tissue engineering provides a new therapeutic idea for cartilage injured cartilage repairing in clinical practice. Electrospinning fibrous scaffold with three-dimensional structure like extracellular matrix is suitable for cell growth and bioactive factor loading for cartilage tissue engineering. This paper introduces studies of the application of electrospinning technology in repairing damaged cartilage by simulating highly hierarchical structures and mechanical features from the aspects of composition optimization, structure optimization and multi-technology combination.
Objective To learn and analyse the current clinicians’ knowledge and attitudes towards patient safety, and to provide relevant evidence for future medical education. Method We conducted a survey on clinicians mainly in West China Hospital of Sichuan University with group random sampling method. We analysed the data on the clinicians’ knowledge and attitudes with SPSS softerware. Result Totally 300 questionnaires were distributed, of which 258 were completed adequately. The results showed the clinicians’ knowledge on patient safety was poor, however, the respcnse from the clinicians in Outpatient Department were better than those in Inpatient Department. The majority of the clinicians (above 95.00%) were willing to learn the knowledge of patient safety. Conclusion As the clinicians are willing to learn the knowledge of patient safety positively, it is necessary to integrate patient safety education into the current medical education curriculum.
