RESUMEN
Objective To investigate the relationship between muscle mass reduction and quality of life in elderly lung cancer patients at the initial visit.Methods Totally 221 patients with non-small cell lung cancer undergoing chest and abdominal CT examination were included in this study at Fenyang Hospital in Shanxi Province.The Pearson's correlations of skeletal muscle index(SMI) and skeletal muscle radiodensity(SMD)with the disease stage,physical function,role of physical function,global quality of life,fatigue and dyspnea were analyzed.Results The average age of 221 patients was(70.2t9.0)years.The mean SMI for men and women was(46.7± 7.8)cm2/m2 and(39.4 ±6.4) cm2/m2 respectively.Multivariate linear regression analysis showed that SMI affected the body function,role of physical function,global quality of life,and fatigue dimension(all P ＜ 0.05),and SMD affected the physical function of life quality and dyspnea dimension(P ＜0.05).SMI was related to the physical function and role of physical function(men:r =0.287 and 0.245,P =0.001 and 0.006;women:r=0.296 and 0.395,P =0.004 and 0.000).In male patients,SMO was also associated with low global quality of life and fatigue(r=0.191 and-0.198,P =0.032 and 0.026).The above relationships did not change even after adjusting for the effect of age and disease stages.Low SMD was associated with low physical function and dyspnea in both men and women(men:r =0.287 and 0.245,P=0.037 and 0.049;women.:r=0.281 and-0.262,P=0.006 and 0.010),and SMD was associated with dyspnea only in women even after adjusting for age and disease stages.A correlation between SMI and the disease stage was found in both men and women(male:r =-0.266,P=0.003;female:r=-0.223,P=0.005).Conclusions Changes in muscle mass may affect the physical function,role of physical function and global quality of life in elderly patients with non-small cell lung cancer.
RESUMEN
Objective To explore the effects of application of virtual simulation technology in basic nursing practice teaching.Methods Convenience sampling method was used to select 204 nursing students of grade 2013 in Fenyang College of Shanxi Medical University as the research subjects.Virtual reality software and simulator were used to build realistic experiment environment.Tasks of virtual simulation training were primary,intermediate and advanced.Questionnaire survey was conducted after training to investigate teaching effects,and theoretical and operating test scores of grade 2013 were compared with those of grade 2012.Results In the primary,intermediate and advanced tasks,there were 87.3％,77％ and 60.8％ of the students having scores of 91～100;theoretical and operating test scores of grade 2013 were better than those of grade 2012(P＜0.01);98％ of the students considered virtual simulation enhanced proficiency of operation,93.1％ of the students considered virtual simulation facilitated learning,91.1％ of the students liked virtual simulation learning,and 90.1％ of the students considered virtual simulation stimulated interests in learning.Conclusion The application of virtual simulation experiment teaching in basic nursing practice teaching can promote the innovation of teaching mode and improve the teaching quality and teaching effect.
