RESUMEN
Objective:To explore the module of the construction and application of medical first-aid at the door of the space capsule and the air evacuation.Methods:According to the purpose, principle, and method set by the module, it was divided into two sub-modules: medical first-aid at the door of the space capsule and the air evacuation. During the comprehensive first-aid training, independent training and combined training were carried out respectively according to different mission stages of launch and recovery and different recovery terrain. Meanwhile, research was performed to ensure that medical carrying equipment was lightweight, modular, and portable, and the efficiency of modularization construction was tested in the comprehensive training.Results:The module of medical first-aid at the door of the space capsule and the air evacuation obviously shortened the rescuing time during the comprehensive training, the saving effect was remarkable, and the overall saving efficiency was significantly improved.Conclusions:The module of medical first-aid at the door of the space capsule and the air evacuation meet the requirements that the emergency support system of aerospace medicine should function on an immediate basis, ensuring accurate treatment and air evacuation without any delay, so that to achieve the aim of aerospace medicare.

OBJECTIVE:To study the antihyperglycemic activity of Herba Taraxaci polysaccharides.METHODS:1,1-diphenyl-2-picryl-2-picrylhydrazyl(DPPH) radical scavenging and FRAP assays were used to analyze the antioxidant activity of Herba Taraxaci polysaccharides;the inhibitory activity of ?-glucosidase in vitro was tested by micromethod; the diabetic mice model was established using alloxan. After intragastric administration of Herba Taraxaci polysaccharide for 14 days,the fasting serum glucose and antioxidant parameters (SOD,MDA and GSH-Px) in dissected liver tissue were assayed. RESULTS:The TEAC values assayed by DPPH and FRAP methods were 564.98 ?molTE?g-1 and 1 399.55 ?molTE?g-1,respectively; and the IC50 value of Herba Taraxaci polysaccharides against ?-glucosidase was 49.27 ?g?mL-1.Herba Taraxaci polysaccharides had no effect on serum polysaccharides and antioxidant parameters in normal mice,but which significantly down-regulated the fasting serum glucose of diabetic mice especially at a high dosage(P

OBJECTIVE:To establish a HPLC method for determination of the content of baicalin in Bifukang oral liq?uid.METHODS:The ODS C 18 column was used with methanol-water-glacial acetic acid(45∶55∶1.5)as mobile phase,and de?tective wavelength was274nm,the flow rate was1ml/min.RESULTS:Within the range of0.215?g～4.3?g,baicalin presented a fine linear relationship between amount and peak area(r=0.9995).The average recovery was99.44%(RSD=0.79%,n=5). CONCLUSION:This HPLC method is convenient,rapid and accurate,and can be used for quality control in the production of Bifukang oral liquid.
