Objective To understand the distribution and change in drug resistance of common pathogens before and after the implementation of special rectification activity on antimicrobial use in 2011-2015,and provide guidance for clinical application of antimicrobial agents.Methods Antimicrobial use in hospitalized patients and pathogens isolated from patients in a hospital from 2011 to 2015 were collected,changing trend of resistance rates of major pathogens to commonly used antimicrobial agents was analyzed.Results From 2011 to 2015,antimicrobial utilization rate in hospitalized patients dropped from 75.84%to 37.35%,antimicrobial use density decreased from 59.53 per 100 patient days to 33.63 per 100 patient days,both showed a downward trend(both P<0.05).A total of 10 091 strains of pathogens were isolated,2 338(23.17%)of which were gram-positive bacteria,7 110(70.46%)were gram-negative bacteria,and 643(6.37%)were fungi.The top five pathogens were Escherichia coli(20.85%),Klebsiella pneumoniae(15.90%),Pseudomonas aeruginosa(11.70%),Staphylococcus aureus(7.35%),and Acinetobacter baumannii(6.82%).Resistance rates of major pathogens to commonly used antimicrobial agents decreased year by year(P<0.05),resistance rates of Escherichia coli and Klebsiella pneumoniae to piperacillin/tazobactam,cefoxitin,and amikacin declined most obviously(all<4%in 2015);compared with Acinetobacter baumannii,Pseudomonas aeruginosa had higher sensitivity to commonly used antimicrobial agents,resistance rates to piperacillin/tazobactam,cefoperazone/sulbactam,ceftazidime,cefepime,amikacin,and ciprofloxacin decreased obviously,resistance rate to above antimicrobial agents was <20%,to carbapenems was higher than other commonly used antimicrobial agents.Resistance rates of Acinetobacter baumannii to amikacin,levofloxacin decreased most obviously,to meropenem and imipenem increased obviously,in 2015 were both above 50%.Resistance rate of Staphylococcus aureus to fluoroquinolones declined most obviously(<2%),vancomycin-resistant strains were not found.Conclusion After the implementation of special rectification activity,resistance rates of common pathogens decreased with the decline of antimicrobial use,rational use of antimicrobial agents may be related to delaying bacterial resistance.

Objective: To investigate the feasibility and efficiency of three-line relaxation-based group intervention on mental stress management among nursing students. Methods: A total of 224 nursing students were randomly divided into the intervention group in which three-line relaxation training for 12 weeks were delivered together with psychological health education (PHE), and the control group which only delivered PHE. The SelfRating Anxiety Scale (SAS) and the Self Rating Depression Scale (SDS) were used before and after intervention. T-test was used to compare inter-group difference. Results: After 4-week intervention, there’s no significant difference in the score of SAS and SDS between the two groups(P>0.05). After 12-week intervention, average SAS and SDS score of intervention group was significantly decreased compared with before intervention (both P<0.01). After 12-week intervention, no significant changes were observed in the score of SAS and SDS in the control group (both P>0.05). After 4-and 12-week intervention, average score in SAS and SDS of intervention group was significantly lower than that of the control group(P<0.05). Conclusion Three-line relaxation is effective in relieving mental stress of nursing students.

Objective: To investigate the prevalence of somatization symptoms and its correlation with social support in patients with depressive disorder. Methods: Two hundred and fourteen hospitalized patients with depressive disorder were recruited. Patients were evaluated with Somatic Symptom Inventory (SSI), Perceived Social Support from Family Scale (PSS-Fa), Social Support Rating Scale (SSRS) and the general questionnaire. Results: The average SSI scores of depressive patients was 49.63±15.53, with 26.2% (56/214) of the patients having moderate to severe level of somatic symptoms. The most common moderate to severe somatic symptoms in depressive patients were "feeling fatigued (61.3%, 131/214), weak (49.5%, 106/214), not feeling well (47.7%, 102/214), feeling faint or dizzy (48.6%, 104/214), or constipation (29.9%, 64/214)" . The average SSRS scores of patients was low (33.24±7.16). The SSI scores and its non-painful dimension (39.05±12.14) were significantly negatively correlated with family support (11.03±3.45) (r=-0.150, P=0.03; r=-0.153, P=0.02) .The SSI scores, and its somatization dimension scores (49.63±15.53) and painful dimension scores (10.58±4.18) were negatively correlated with the total scores of social support (33.24±7.16) (r=-0.164, P=0.02; r=-0.183, P=0.01; r=-0.136, P<0.05) and subjective support (19.14±4.81) (r=-0.167, P=0.02; r=-0.163, P=0.02; r=-0.177, P=0.01) . The SSI scores and its non-painful dimension of patients were negatively correlated with support utilization (r=-0.179, P=0.01; r=-0.194, P=0.01) . Conclusion Somatic symptoms are prevalent and severe in patients with depressive disorder. The somatic symptoms of depressive patients was closely correlated with decreased social support, especially low subjective support and support utilization.
