Objective To determine the prevalence and treatment of chronic obstructive pulmonary diseases (COPD) among citizens in Ningbo. Methods A multi-stage stratified random sampling was applied to select 8 neighborhoods and 3 villages out of 7 districts in Ningbo, people who were older than or equal to 40 years were enrolled as subjects. Information on the prevalence rate and treatment conditions of COPD was collected through respiratory symptoms and treatment questionnaire and lung function screening. Results A total of 5865 people were screened, 5674 of them met inclusion criteria and completed questionnaire and lung function test. Among whom, 3044 people were men (53.6%, the average age is 55.7±11.4), 2630 women (46.4%, the average age was 55.3 ± 10.7);473 of them were diagnosed with COPD, the overall prevalence rate was 8.3%, including 354 cases who had never been diagnosed as COPD, accounted for 74.8% of the total cases diagnosed with COPD, mainly in stage ⅠandⅡof the disease. There were statistically significant differences between diagnosed and undiagnosed patients in the overall COPD group and among different gender groups ( stagesⅠandⅡ) and (stagesⅢandⅣ). Among the 473 COPD cases, 119 (diagnostic yield 25.2%) of whom had been diagnosed with bronchitis, only 48 (41.2%of the diagnosed) received drug treatment, only 13 patients were treated regularly with medication. Conclusion The overall prevalence rate of COPD among those over 40 years of age in Ningbo was quite high and mainly had stagesⅠandⅡof the disease. The number of the diagnostic yield and those who received regular treatment are quite low. The current situation of diagnosis and treatment are far from satisfaction, management of COPD should be strengthened to reduce the burden for family and society.

Objective To compare the amplitude and latency of event-related potential P300 be-tween impulsive and predictive violent criminals. Methods Twenty impulsive violent criminals and twenty predictive violent criminals were recruited from one prison in Wenzhou city. Twenty matched healthy controls from community were recruited. Criminals in both groups were excluded from violent crimes caused by mental disorders by judicial psychiatrists using DSM-IV axis I disorder clinical stereotyped interviews. Nicolet Bravo Brain Evoked Potentiometer (produced by Nicolet Company,USA) was used to detect the P300 components of the above three groups of subjects. Eysenck Impulsiveness Scale was used to assess the impulsiveness. Results The P300 amplitude of impulsive violent criminals was smaller than that of predictive violent crimi-nals( (4. 52±1. 14)μV vs (13. 88±2. 06)μV,t=17. 779,P<0. 01),but there was no significant difference of the P300 amplitude between predictive violent criminals and community enrolled controls ((13. 88±2. 06) μV vs (14. 01±1. 86)μV,t=0. 209,P=0. 835). The impulsivity scale score of impulsive violent criminals was highly negatively correlated with the amplitude of P300 (r=-0. 812,P=0. 002). There were no signifi-cant differences in the latency of P300 among impulsive violent criminals,predictive violent criminals and community enrolled controls group. And there was no significant correlation between the latency of P300 and the score of impulsivity scale (P>0. 05). Conclusion The P300 amplitude can aid in the differential diag-nosis of violent criminals with and without impulsive behavior.

Objective: To investigate and summarize the effect of narrative nursing on anxiety and depression in patients undergoing coronary artery bypass grafting, and to provide reference for the formulation of clinical nursing plan. Methods: A total of 61 patients underwent coronary artery bypass grafting were selected. 31 cases of narrative nursing were taken as the research group, and routine nursing was used in the other 30 cases as control group. Depression and anxiety were assessed by Self-rating Depression Scale (SDS) and Self-rating Anxiety Scale (SAS) before, 7 days after and 14 days after surgery. Results: Totally 61 patients were successfully operated and no case died during hospitalization. There was no significant difference in SAS and SDS scores between the 2 groups before surgery. The SAS scores in the study group were 57.9±4.2, 50.8±4.9, 47.1±5.0 on the day of admission,7 days after operation and 14 days after operation, respectively, while those in the control group were 58.4±3.7, 57.9±5.2, 55.7±6.2. There were significant differences between the two groups after intervention (t=5.490, 5.973, P<0.01). The SAS score of the study group decreased 7 days after operation and 14 days after operation compared with that of the admission day (t= 6.125, 9.209, P < 0.01). The SDS scores in the study group were 54.3±4.6, 49.4±4.7, 42.7±4.8 on the day of admission,7days after operation and 14 days after operation, respectively, while those in the control group were 54.1±5.1, 52.3±5.6, 51.6±5.2. There were significant differences between the two groups after intervention (t=2.194, 6.949, P<0.01). SDS scores in the study group decreased 7 days after operation and 14 days after operation compared with the day of admission in this group, with significant differences (t=4.148, 9.715, P < 0.01). Conclusions Narrative nursing is helpful to relieve anxiety and depression in patients undergoing coronary artery bypass grafting.
