Objective To develop the Chinese version of Attribution Questionnaire-27 and examine its replicability,reliability and validity.Methods The questionnaire was translated using the standard translation/back-translation method and examine its replicability,reliability and validity in 230 medical students who were selected by convenient method.Results The Cronbach α coefficient for Attribution Questionnaire-27 was 0.82 and ranging between 0.55 and 0.84 for the subscales.The test-retest reliabilities of the total scale was 0.77 and the subscales was between 0.61 to 0.81 after one week.Confirmatory factor analysis confirmed the hypothesized six factors attribution of responsibility model (x2/df=3,GFI=0.925,NFI=0.880,CFI=0.856,IFI=0.761,RMSEA=0.094) and three factors dangerous model (x2/df=1.773,GFI=0.959,NFI=0.941,CFI=0.973,IFI=0.973,RMSEA=0.058).The path analysis results support the existing theoretical assumptions.Condusions The Chinese version of Attribution Questionnaire-27 has good reliability and validity and can be used in medical student.

Objective To investigate the status of nurses' resilience and to explore the related factors.Methods 1356 nurses from 11 level Ⅱ and level Ⅲ hospitals of Guangzhou were assessed by using the general information questionnaire and the Chinese version of Conner-Davidson resilience scale.Results The score of nurses' resilience was(59.99±13.59)points and it was significantly lower than that of the domestic norm.There was statistical difference of the score of nurses' resilience on different genders,educational background,professional titles,hospital level and night shifts.There was a positive correlation among educational background,night shifts and nurses' resilience,and a negative correlation between hospital level and nurses' resilience.The hospital level,night shifts and educational background were the influencing factors of nurses' resilience.Conclusions The level of nurses' resilience is low.The higher hospital level and educational background,and the less night shift,the higher of nurses' resilience.

Objective To investigate the influence of stigma on QOL of patients with mental disorders.Methods By using Link stigma series scale and schizophrenic quality of life scale,we assessed and analyzed 406 psychiatric patients′stigma and QOL, as well as the correlation and influence between them.Results The score of perceived devaluation-discrimination dimension of the stigma scale had positive correlation with total score of QOL,score of psycho-social dimension and score of motivation and energy dimension (P <0.05).The scores of challenge dimension and separation dimension in the stigma scale had positive correlation with motivation and energy dimension of the QOL scale (P <0.05).Regression analysis showed that stigma did not have influence on QOL of patients with mental disorders.Conclusion Stigma in psychiatric patients has no significant influence on QOL,but correla-tion relationship exists between them.The higher score of perceived devaluation-discrimination dimension,challenge dimension and separation dimension of stigma scale,the poor QOL the patient would have.

Objective:To compare the effects of pressure controlled ventilation (PCV) and volume controlled ventilation (VCV) on respiratory mechanics, hemodynamics and biochemical metabolism in patients undergoing laparoscopic colorectal cancer surgery.Methods:The clinical data of 78 patients underwent laparoscopic colorectal cancer surgery from August 2019 to June 2020 in Inner Mongolia People′s Hospital were retrospectively analyzed. Among them, 39 patients were treated with PCV (PCV group), and 39 were treated with VCV (VCV group). The respiratory mechanics, hemodynamics and biochemical metabolism indexes 10 min after anesthesia induction (T 1), 10 min after pneumoperitoneum + low head and foot height (T 2), 60 min after pneumoperitoneum + low head and foot height (T 3) and 120 min after pneumoperitoneum + low head and foot height (T 4) were recorded. The respiratory mechanical indexes included mean airway pressure (P mean), airway peak pressure (P peak), pressure of end tidal carbon dioxide (P ETCO 2) and dynamic lung compliance (C Ldyn); hemodynamic indexes included mean arterial pressure (MAP) and heart rate; and biochemical metabolic indexes included base excess, serum natrium, serum potassium, negative logarithm of the hydrogen ion concentration (pH) and blood glucose. Results:The P mean, P peak and P ETCO 2 T 1 to T 4 in PCV group were significantly lower than those in VCV group, P mean: (7.12 ± 1.37) cmH 2O (1 cmH 2O = 0.098 kPa) vs. (8.54 ± 1.84) cmH 2O, (9.80 ± 2.26) cmH 2O vs. (11.63 ± 2.87) cmH 2O, (9.51 ± 2.17) cmH 2O vs. (11.72 ± 2.90) cmH 2O, (7.04 ± 1.34) cmH 2O vs. (8.65 ± 1.88) cmH 2O; P peak: (13.41 ± 2.68) cmH 2O vs. (15.06 ± 3.05) cmH 2O, (20.92 ± 3.11) cmH 2O vs. (23.45 ± 4.02) cmH 2O, (21.14 ± 3.50) cmH 2O vs. (23.69 ± 4.26) cmH 2O, (15.03 ± 2.74) cmH 2O vs. (16.45 ± 3.21) cmH 2O; P ETCO 2: (30.59 ± 1.57) mmHg (1 mmHg = 0.133 kPa) vs. (32.04 ± 2.11) mmHg, (35.02 ± 4.15) mmHg vs. (39.88 ± 4.76) mmHg, (35.90 ± 4.22) mmHg vs. (40.11 ± 4.87) mmHg, (34.33 ± 4.17) mmHg vs. (37.65 ± 2.69) mmHg; the C Ldyn was significantly higher than that in VCV group: (40.68 ± 3.98) ml/cmH 2O vs. (35.47 ± 2.56) ml/cmH 2O, (30.25 ± 3.21) ml/cmH 2O vs. (22.40 ± 2.75) ml/cmH 2O, (29.78 ± 3.06) ml/cmH 2O vs. (22.60 ± 2.81) ml/cmH 2O, (40.32 ± 4.25) ml/cmH 2O vs. (33.61 ± 2.81) ml/cmH 2O, and there were statistical differences ( P<0.01 or <0.05). The MAP and heart rate T 1 to T 4 in PCV group were significantly lower than those in VCV group, and there was statistical difference ( P<0.01 or <0.05). The base excess, serum natrium, serum potassium and pH T 1 to T 4 in PCV group were significantly higher than those in VCV group, while the blood glucose was significantly lower than that in VCV group, and there was statistical difference ( P<0.01 or <0.05). Conclusions:Compared with VCV, PCV can promote the recovery of respiratory mechanics index, stabilize hemodynamics and improve biochemical metabolism index in patients undergoing laparoscopic colorectal cancer surgery.
