摘要：To improve the efficiency and correctness of the review,we aimed to continuously improve the review strategy of parenteral nutrition(PN)prescriptions.A calculation formula(CF)and an electronic prescription reviewing system(EPRS)were designed to improve *** improvements were divided into three periods:pre-improvement,improvement period-1(CF was used),and improvement period-2(EPRS-CF was used).A retrospective analysis for inpatients receiving PN support from January to May 2019,June to October 2019,and June to October 2020,was conducted to evaluate the defect and efficiency of the PN prescription *** with the pre-improvement period,the efficiency of the PN prescription review in the CF period was *** addition,in the EPRS-CF period,the efficiency and correctness of the PN prescription review were remarkably increased(P<0.01).Moreover,through the verification of PN prescriptions in the EPRS-CF period,pharmacists improved the efficiency and correctness of the PN prescription ***,the PDCA(plan-do-check-act)circulation method could help improve the PN reviewing process in the future.

摘要：Background Artificial joints present certain problems such as osteal absorption and lysis induced by wear debris which leads to loosening of the prosthesis over a period of time. Here we propose a design of an artificial magnetic suspension joint that was prepared by integrating the medical theories of modern material science, magnetism, and medical *** According to clinical characteristic of biological and mechanical for hip joint, we designed the appearance and dimensions of magnetic suspension joint and placed neodymium-iron-boron permanent magnets in the *** the same time, we performed mechanical and biological experiments using artificial magnetic suspension hip joints *** By simulated the human hip structure and the external load, we discovered the artificial magnetic suspension hip joints models had much lesser amount and size of wear debris than the ceramic/ceramic artificial hip joint prosthesis in friction wear tests. The force between the artificial joints with magnetic materials that we have calculated is feasible for application of artificial joint. The design of artificial magnetic suspension hip joints models was plausible technically and safe *** Artificial magnetic suspension hip joints may effectively reduce the incidence of the loosening of prosthesis over a period of time.
