Objective To study the psychological defence (PD) and coping style (CS) of the patients suffering depressive episode (DE).Methods 104 cases of the experimental group and 104 cases of the control group,which were stratified sampled,had been investigated by applying defensive style questionnaire (DSQ),coping style questionnaire(CSQ).Results The total score of the immature PD of the experimental group(5.19±0.73) was significantly higher (t =2.93,P＜ 0.05) than that of the control group (4.41 ± 0.76).In the immature mechanism,withdrawal,somatization,avoiding,passive aggression were significantly higher,but the complaints and fantasy were significantly lower.The total score of mature PD of the experimental group(4.49±0.61) was significantly lower (t=-6.02,P＜0.01) than that of the control group(6.01±0.85).For the mature mechanism,sublimation and humor were lower and the repression was higher.And for the CS,problem solving,consulting and rationalization scores were significantly lower than those of the control group(t=-4.58,P＜0.01 ; t=-4.49,P＜0.01; t=-4.01,P＜0.01).The self-accusation,retreat scores were significantly higher than those of the control group(t=8.21,P＜0.01; t=5.31,P＜0.01).Conclusion Patients suffering DE are apt to use immature PD and CS.To increase the therapeutic effect,the style of the patients' PD and CS should be highlighted,and it is necessary to take steps to guide the patients to use mature PD and CS.

Objective To identify antimicrobial susceptibilities of community-acquired Staphylococcus aureus infections and the risk factors of severe infections.Methods Clinical data of 184 cases of community-acquired Staphylococcus aureus infections collected from 4 hospitals in Ningbo during May 2008 and May 2013 were reviewed.Microbial sensitivity test and virulence genes ( pvl and tst) detection were performed in clinical isolates, and SCCmec genotyping was performed in methicillin-resistant Staphylococcus aureus ( MRSA) strains.Binary logistic regression analysis was used to identify the risk factors for severe infections.Results Among 184 cases of community-acquired Staphylococcus aureus infections, 39 ( 21.20%) were severe cases. Staphylococcus aureus strains were highly resistant to penicillin, erythromycin and clindamycin, but more than 75% strains were sensitive to oxacillin, aminoglycosides, quinolones, rifampicin and vancomycin.Logistic regression analysis showed that advanced age (OR=1.024, 95%CI:1.005-1.043, P<0.05), malignant tumor (OR=15.288, 95%CI:1.609-145.229, P<0.05) , autoimmune diseases or long-term hormone therapy ( OR=12.102, 95%CI:2.082-70.338, P <0.01 ) were risk factors for severe community-acquired Staphylococcus aureus infections. Conclusions Strains isolated from the patients with community-acquired Staphylococcus aureus infections in Ningbo are usually sensitive to oxacillin, aminoglycosides, quinolones, rifampicin and vancomycin, which may be recommended for clinical use.Elder patients and those with malignant tumor, autoimmune diseases or long-term hormone therapy are more likely to develop severe Staphylococcus aureus infections.
