RESUMEN
Objective To explore the key initiatives and effective methods for preparing the constructions of emergency-oriented hospitals under COVID-19 pandemic. Methods The wartime mechanism was strengthened by adhering to unified leadership, trengthening the top-level design and clarifying the division of responsibilities. Objective management was used as a means to take into account the key of personnel allocation and training, prevention and control of hospital infection, transformation of contagious ward, logistic support, equipment and material supply and construction of system and process. Results The preparations and constructions of the emergency-oriented hospitals were completed in 72 hours，which passed the acceptance and inspections from infection control experts，who appraised our work to be “the highest in difficulty, the fastest in project progress and the highest in quality". Totally, upon to the preparations，14 medical teams were set up and the layout process reestablishment of 14 wards was completed, the installation and preparation of nearly 10000 sets/pieces of medical equipment and medical materials were completed as well and more than 80 work systems and process systems for 9 major modules were established. Conclusion The preparations and constructions of emergency-oriented hospitals should be performed upon the thorough implementation of the decisions and arrangements by the municipal Party committee and the municipal government, insisting on the wartime thinking and establishment of high-quality management team and effective goal management focusing on details and actual needs of medical staff.
RESUMEN
In this report, a heat and high-pressure homogenization method was used to prepare dioscin nanostructured lipid carriers, and the formulation of dioscin nanostructured lipid carriers was optimized by central composite design-response surface methodology. In vitro evaluation data showed that the preparation of dioscin nanostructured lipid carriers under optimal process by central composite design-response surface methodology had a spherical shape and homogeneous size distribution, with a particle size of (90.9±0.6) nm, a polydispersity index of (0.253±0.07), Zeta potential of (-45.7±0.5) mV, encapsulation efficiency of (90.2±0.5)%, and the drug loading of (23.30±0.10)%. These results clearly indicate that the preparation of dioscin nanostructured lipid carriers made with the heat and high-pressure homogenization method have very good physical and chemical properties, suitable for therapeutic applications.
