Objective To investigate the intermediary and regulating effect of self?esteem on per?ceived stress and training burnout among accelerated plateau soldiers. Methods A total of 700 accelerated plateau soldiers were investigated which were chosen by a random cluster sampling method,and assessed by the Perceived Stress Scale, Self?esteem Scale and Self?compiled Soldiers' Training Burnout Questionnaire. Results ( 1) The total score of training burnout,the score of physical and mental exhaustion and the score of training alienated among soldiers who had a history of training injury (27.85±5.80,14.89±3.46 and 6.89± 2.26,respectively) were significantly higher than those of soldiers who didn't have a history of training injury (25.05±5.12,12.68±3.25 and 6.16±2.78,respectively),and the differences were significant ( t= 4.321, 5.764,2.825,all P<0.01). The total score of training burnout,the score of physical and mental exhaustion and the score of training alienated among soldiers who had a high training expectation were higher than those of soldiers who didn't have a high training expectation,and the differences were significant (P<0.01). (2) Among accelerated plateau soldiers,training burnout showed significantly positive correlation with perceived stress ( r=0.323, P<0.01),and significantly negative correlation with self?esteem ( r=-0.409, P<0.01). (3) The intermediary role of self?esteem between perceived stress and training burnout was remarkable (P<0.01) ,which accounted for 33.8% of the total effect,and self?esteem also had a regulating effect (P<0.05) . Conclusion Radical plateau soldiers have remarkable differences due to the history of training injury or training expectations,and self?esteem has partial intermediary and regulating effect between perceived stress and training burnout.

OBJECTIVE:To study the in vitro uptake of Resibufogenin(RBG)lactic acid glycolic acid copolymer-water solu-ble vitamin E (PLGA-TPGS) in human liver cancer HepG2 cells,mouse ascites-type lymphatic metastasis of tumor HCa-F cells, and the toxicity on HepG2 cells. METHODS:RCPTN loading RBG and coumarin-6(C6)were prepared. Fluorescent inverted mi-croscope was used to observe the in vitro uptake by RCPTN HepG2,HCa-F cells. It was divided into negative control group,blank PLGA-TPGS nanoparticles(EPTN)group,5-fluorouracil solution(FS)group,RBG solution(RS)group,RBG/PLGA nanoparti-cles(RPN)group and RPTN group. WST-1 was conducted to investigate the optical density at 450 nm wavelength of HepG2 cells after 24,48,72 h incubated by FS,RS,RPN and RPTN with different final concentrations (1.25,2.5,5,10,20 μg/mL);the cell viability (CV) and half inhibitory concentration (IC50) were calculated. RESULTS:RCPTN distributed around the nucleus of HepG2,HCa-F cells. CV was decreased by RBG concentration increased in RPN group and RPTN group,and decreased by time prolonged;compared with FS group,CV in RPTN group was decreased(P<0.05 or P<0.01). IC50 of HepG2 cells incubated by FS,RS,RPN and RPTN was decreased by time prolonged,ordered by RS>FS>RPN>RPTN;IC50 incubated by RPN and RPTN for 48,72 h was obviously less than that of FS and RS(P<0.05 or P<0.01). CONCLUSIONS:RPTN can deliver RBG in-to HepG2,HCa-F cells,showing inhibition effect on HepG2 cells which is stronger than RPN,RS and FS.
