Objective To investigate the general self-efficacy of the clinical nurses and explore the relationship between general self-efficacy and job burnout .Methods 473 clinical nurses from 13 hospitals of the third and the second grade in Leshan city were recruited and investigated with general self-efficacy scale and mashach burnout inventory .Results (1)The mean score of the clini-cal nurses′general self-efficacy was(2 .63 ± 0 .49) scores ,which was lower than that of military nurses (2 .69 ± 0 .58) scores (P<0 .05) .(2)There was a significant difference of nurses′general self-efficacy in different employment types ,administrative positions , marital statuses ,length of service and professional titles (P<0 .05) .(3)The score of general self-efficacy was negatively correlated with that of emotional exhaustion and of depersonalization (P<0 .01) ,but positively correlated with that of personal accomplish-ment(P<0 .01) .Conclusion Nurses′overall general self-efficacy was at a moderate level .Administrators could reduce nurses′job burnout more effectively by improving their self-efficacy .

Objective To detect the serum level of 3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid (CMPF),a significant metabolite offish oil,in subjects with normal glucose tolerance (NGT) in local communities,and to investigate the association of CMPF with fatty acid metabolism.Methods A total of 272 NGT participants from screening for diabetes in Shanghai in 2013 were enrolled.Anthropometric measurements,biochemical evaluation,and questionnaire interview were performed for all the participants.The participants were divided into normal weight group [body mass index (BMI) ≤23.9 kg/m2,n =143] and overweight/obesity group (BMI ≥ 24 kg/m2,n =129).The serum CMPF concentrations were determined using an enzyme-linked immunosorbent assay.Results Serum CMPF level in overweight/obesity group was lower than that in normal weight group [96.50 (46.11,169.56) μmol/L vs 153.20 (83.16,282.97) μmol/L,P＜0.05].The serum CMPF level was negatively correlated with BMI (r =-0.256,P＜0.01),triglycerides (r =-0.175,P =0.004),and free fatty acid (r =-0.126,P =0.041) according to bivariate correlation analyses.A multivariate stepwise linear regression analysis showed that the serum CMPF level was independently associated with BMI,triglycerides,free fatty acid,and HbA1C.A logistic regression analysis showed that the CMPF was a protective factor against obesity (OR =0.324,95％ CI 0.158,0.664).Conclusion Serum CMPF level is reduced in overweight/obese subjects.CMPF is beneficial to lipid metabolism.
