Objective To explore the correlation between health value and health-promoting lifestyle in elderly people at nursing home. Methods Totally 130 elderly people from nursing home were investigated with health value scale and health-promoting lifestyle profile II to understand the status of their health value and health-promoting lifestyle and the correlation between them. Results The mean score of health value was 7.78±1.58, which was in the middle level;The mean score of health-promoting lifestyle was 132.78±14.99. Among all dimentions. nutrition scored highest, while health responsibility and physical activity scored lowest. The health value was positively correlated with the health-promoting lifestyle among nursing home elderly people (P<0.01). Their own health status and health value were influencing factors of health promoting-lifestyle, which could be explained at 43.5%of the variance. Conclusions The nursing home for elderly people were good in health value and average in health-promoting lifestyle. The elderly with a higher health value had better health-promoting lifestyle. Health care workers should improve elderly people′s level of health value, and give more help and guidance to the elderly people for physical activity and health responsibility, making them establish healthy lifestyle.

Objective To prospectively assess the diagnostic accuracy of MR inflow inversion recovery (IFIR) fast imaging employing steady-state acquisition (FIESTA) for detection of renal artery stenosis (RAS),as compared with renal artery CT angiography (CTA) performed as the reference standard.Methods Thirty patients [18 males,12 females; mean age (65.0±12.1) years] with arterial hypertension and suspected RAS were examined by 3.0-T 3D MR IFIR-FIESTA and renal artery CTA within a week.The IFIR-FIESTA image quality,the IFIR-FIESTA and CTA in display of second-order and third-order branches of renal artery were assessed by two experienced readers.The sensitivity,specificity,accuracy,and negative predictive value (NPV) of IFIR-FIESTA were calculated on artery-by-artery and patient-by-patient bases by the two readers.The inter-observer agreement between the two readers in determining the presence and grade of renal artery stenosis was assessed.Results The scores of qualification of IFIR-FIESTA image quality by reader A and B were (2.16±1.02) and (2.00 ± 0.14),there was no significant difference between them (Z=-0.037,P=0.971).IFIR-FIESTA and CTA in display of second-order and third-order branches of renal artery had no significant difference (x2 =0.298,P=0.585).In the assessment of all 64 main renal arteries by reader A,IFIR FIESTA on artery-by-artery basis had sensitivity,specificity,accuracy,and NPV of 100％,96％,97％,and 100％,respectively; the above parameters assessed by reader B were 100％,90％,93％,and 100％,respectively.There was excellent inter-observer agreement (Kappa=0.803) with the presence or absence of hemodynamically significant RAS.In the assessment of all 30 patients by reader A,IFIR-FIESTA on patient-by-patient basis had sensitivity,specificity,accuracy,and NPV of 100％,95％,97％,and 100％; the above parameters assessed by reader B were 100％,85％,90％,and 100％,respectively; there was good inter observer agreement (Kappa=0.724) with the presence or absence of hemodynamically significant RAS.Conclusions Compared with CTA,MR IFIR-FIESTA can excellently assess RAS without contrast material and radiation exposure,therefore,it can be used for screening of RAS,especially should be widely applied to elderly patients with arterial hypertension.
