Objective To investigate in vitro activity of antimicrobial agents against Enterococcus spp . isolated from clinic specimens in a hospital.Methods 188 Enterococcus spp . isolates from specimens sent by clinic depart-ments in June 2013-July 2014 were identified and performed antimicrobial susceptibility testing.Results Of 188 En-terococcus spp . isolates,119 were Enterococcus faecium (E.faecium),60 were E.faecalis ,and 9 were E.avium, these strains were mainly isolated from urine (34.57%)and blood specimens (19.15% ).No daptomycin and linezolid-resistant strain was detected;resistant rates of E.faecium to vancomycin was 1 .68%,to penicillin, ampicillin,high concentration gentamycin,erythromycin,and levofloxacin were all > 70%;except tetracycline, resistant rates of E.faecalis to the other antimicrobial agents were all lower than E.faecium,resistant rates of E. faecalis to penicillin and ampicillin were 16.67% and 13.33% respectively.Conclusion Daptomycin has high activity against Enterococcus spp . in this hospital.

Objective To investigate the best evidence application of exercise prescription in patients with chronic heart failure in clinical practice and evaluate its effectiveness.Methods The best evidence of exercise prescription for patients with chronic heart failure was summarized,and the evidence-based practice plan was developed,and it was implemented in the cardiology department of a tertiary hospital in Zhejiang Province from August to October,2022.Nurses'exercise prescription knowledge-attitude-practice level,implementation rate of review indicators,the length of hospital stay,exercise endurance,daily living ability and grip strength of both groups before and after the intervention were compared.Results After the application of the best evidence,the score of knowledge dimension was(9.34±0.98)points;the score of attitude dimension was(63.29±1.37)points;the score of practice dimension was(25.49±1.51)points,which were statistically significant compared with the scores before the application of evidence(P<0.05).After the application of the best evidence,the implementation rate of 16 review indicators was higher than that before the application of evidence(P<0.001).The length of hospital stay in the evidence application group was shorter than that in the baseline examination group(Z=-2.610,P<0.001).After intervention,the exercise endurance,daily living ability and grip strength of patients in the evidence application group were improved compared with the baseline review group,and the difference was statistically significant(P<0.05).Conclusion After the application of the best evidence of exercise prescription in patients with chronic heart failure,it can improve the level of knowledge,attitude and practice of nurses on exercise prescription,standardize the compliance of nurses'exercise prescription,reduce the number of days in the hospital,and improve patients'exercise endurance,daily living ability and grip strength.
