Objective: To explore the depression stares of the elderly experienced the Wenchuan earthquake and to know the related factors. Methods: Using the convenient sampling method, 390 elderly living in Chengdu and Deyang City were included in this investigation. Demographic data was recorded and the Center for Epidemiolog-ic Studies Depression (CES-D) was applied individually. Results: In this sample, 9.8% of the elderly had sus-pected depression symptom and 30.3% had depression symptom. Depression status was related to sex, education,habitual residence, occupation and experiences in earthquake. Compared with the elderly who were males, with middle school education degree, without horrible experiences in the past, with less fearful/helpless/horrible feel-ings in earthquake, the elderly who were females (OR=2.03), with education degree below primary school (OR =2.59), with horrible experiences in the past (OR=2.06), and with strong fearful/helpless/horrible feeling in earthquake (OR=1.59), had more serious depression. Conclusion: After 8 months of Wenchuan earthquake, lo-cal elderly victims are still in severe depression. The elderly who are female, with low education level, engaged in farm work, suffered great loss should be paid special attention.

Objective: To test applicability of the Center for Epidemiological Studies Depression Scale (CES-D) in different age groups in urban China, and to develop age norms. Methods: In this cross-sectional study, the CES-D was administrated to 16047 community participants with average age of (37.7±21.3) years (age ranged 11～100) in 21 provinces, who were as the norming sample. Criterion validity was tested in 349 psychiatric patients with average age of (32.0±12.1) years (age ranged 16～81) in 4 cities. A subsample (199 workers, 100 col-lege students, and 30 teachers in Beijing, Dongguan, and Baotou) was drawn from the national sample to provide 8 week interval test-retest reliability. Results: The Cronbach α was 0.90 for the scale, and 0.68～0.86 for its fac-tors. The 8 week interval test-retest correlation was 0.49 for the scale (P <0.01) and 0.39～0.51 for factors (P<0.01) . The result of confirmatory factor analysis supported the original 4-factor structure (RMSEA=0.057, CFI =0.976, GFI=0.948) . Patients scored higher than community sample [(21.72±13.39 ) vs.(13.24±10.33),P <0.01], and depression patients scored the highest [(27.82±14.42), P<0.01] . Age difference was signifi-cant. Age groups over 60-year-old scored higher than all the other age groups under 60-year-old (P<0.01). Con-clusion: The Chinese version of CES-D shows good refiability and validity across all ages in urban population-

Objective:To explore the relationship between core competence, emotional intelligence and depression of nurses.Methods:A cross-sectional survey was conducted on 505 clinical nurses by general data questionnaire, competency inventory for registered nurse, emotional intelligence scale and the primary care evaluation of mental disorders from December 2020 to February 2021.SPSS 23.0 software was used for statistical analysis, and the correlation was obtained by Pearson correlation analysis, and Model 4 in PROCESS V3.4.1 macro program was used to test the mediating effects.Results:The depression score of nurses was(12.42±5.83), and significant differences were found in depression scores at various levels of gender, marital status, and conscious nurse-patient relationship ( F/ t=3.060, 2.678, 3.210, all P<0.05). Core competencies(149.72±54.87) had a positive correlation with emotional intelligence(82.42±15.62)( r=0.967, P<0.01), and depression scores had a negative correlation with core competencies and emotional intelligence ( r=-0.931, -0.928, both P<0.01). The depression level was negatively predicted by core competence of nurses ( β=-0.528, P<0.01). The capabilities of assessing and expressing their own emotions, identifying and assessing others' emotions and managing their own emotions played partial mediating roles, and the effect size were 49.257%(-0.199/-0.404), 16.089%(-0.065/-0.404) and 27.228%(-0.110/-0.404), respectively. Conclusion:Nurses' core competence is a primary factor influencing their depression levels, with emotional intelligence playing a partial mediating role.In addition, nurses' depression level can be reduced by improving the core competence and emotional intelligence of nurses.

Objective:To investigate how medical students process Western medicine(WM)terms vs.traditional Chinese medicine(TCM)terms and how this is impacted by analogical priming from the perspective of cognitive neuroscience.Methods:The experiments were designed as a 2(TCM terms vs.WM terms)x 2(correct terms vs.incorrect terms)x 2(analogical priming task vs.non-priming task)scheme.A total of 26 medical stu-dents completed a non-priming judgment task and an analogical priming judgment task on medical terms.During the tasks,the participants were asked to make correct/incorrect judgments on WM terms and TCM terms,and their behavioral data and event-related potentials(ERPs)were recorded.Results:Behaviorally,the response speed and accuracy of WM terms were higher than those of TCM terms(both P＜.001),indicating a prominent concreteness effect.Analogical priming shortened the response time to medical terms(P＜.001),and the response time to TCM terms was shortened more significantly(P=.001).For ERPs,WM terms induced a larger P200(an early positive ERP component),a smaller N400(a negative ERP component),and a higher late positive ERP component,indicating supe-riority of attention adjustment,smaller-scale semantic activation,and a higher cost of late semantic analysis and integration.However,the analogical priming eliminated the difference between WM and TCM terms in P200 and N400 while maintaining it in the LPC.This suggests that WM terms are sensitive to analogical attention adjustment,and TCM terms are susceptible to analogical semantic integration.Conclusion:Our findings suggest that WM and TCM disease behavior terms may initially differ in concreteness or the use of a verbal-linguistic system.Analogy is more conducive to understanding TCM terms.This research provides important neuroscientific evidence of the difference in thinking between TCM and WM.

Objective To explore the impact of emotional conflicts on the emotional attention pro-cessing between the elderly and the young. Methods A total of 37 young and 37 elderly participants were enrolled in the study. 2 (group:old group,young group) × 2 (Emotional valence of face:happy,fear) × 2 ( cue type:consistent and inconsistent) mixed experimental design was used among the emotional stroop task and eye tracking task for all of subjects. Results (1) Behavioral response analysis showed that stroop in-terference effects in young and old groups were not significant under different emotional conditions (F=0. 02, P>0. 05). (2) The internal characteristics of the face for the gaze time were analyzed,and the total gaze time of the elderly group (( 402. 28 ± 15. 88) ms ) was significantly longer than that of the younger group ((340. 52±15. 88) ms) under the happy-inconsistent condition(t=2. 75,P<0. 05). The total gaze time of the elderly group under the happy-inconsistent condition was significantly longer than under the fear-inconsis-tent condition((365. 96±13. 95) ms)(t=4. 32,P<0. 05). The first gaze time for a happy face was signifi-cantly longer than that for the fear face((315. 56±13. 13)ms vs (293. 51±13. 23)ms,t=4. 33,P<0. 05), and also showed a positive effect. Conclusion Emotional conflicts have an impact on the emotional atten-tion processing of the elderly,and the elderly are more likely to process the positive stimulation in the control stage.

Objective:To explore the neutral mechanism of influence of long-term exposure to high altitude hypoxia environment on the processing stage of conflict inhibition.Methods:Differences in the electroencephalogram during a 2-1 mapping Stroop task were compared between a high-altitude (HA) group ( n=20) who lived in a high-altitude area (3 650 m) for two years, and a low-altitude (LA) group ( n=20) who had never visited high-altitude areas. Results:The HA group had a higher pulse rate ((82.0±9.7)/min vs (74.0±11.3)/min) and lower oxygen saturation level ((90.7±2.8)% vs (97.4±1.1)%) compared with LA group.Behavior data showed that the reaction time (RT) in congruent (CO) condition was shorter than that in stimulus incogruent (SI) condition, and the RT in SI condition was shorter than that in RI condition ((707.91±70.33)ms vs (753.76±72.96)ms vs (803.88±73.21)ms); accuracy(ACC) rate in SI condition was higher than CO condition, and the ACC in CO condition was higher than RI condition((96.35±2.91)% vs (95.90±2.83)% vs (91.55±5.22)%). And the response conflict effect was larger than the stimulus conflict effect((49.76±33.90) vs (23.60±30.20)). The differences were all statistically significant (all P<0.01). In SI condition, the RT of HA group was longer than LA group((730.43±60.50)ms vs (777.09±78.23)ms) ( P<0.05). As for the EEG, the amplitude of P2((6.18±0.62)μV vs (3.21±0.62)μV) and N450((1.39±1.48)μV vs (5.91±1.48)μV) component of the HA group were higher those that of the LA group.The amplitude of N450 at P4 electrode site was larger than that at P3 electrode site in HA group((2.26±1.34)μV vs (0.62±1.43)μV). The differences were all statistically significant (all P<0.05). Conclusion:Long-term exposure to high altitude hypoxia environment affects the early stage of stimulus perception and task retrieval, as well as the conflict monitoring in later stage of stimulus and response conflict.The HA group need compensation of right parietal to complete the conflict monitoring of stimulus and response conflict.

Objective To perform theory construction and empirical study of the competency model of rural general practitioners. Methods Through literature study, job analysis, interviews, and expert team discussion, the questionnaire of rural general practitioners competency was constructed. A total of 1458 rural general practitioners were surveyed by the questionnaire in 6 central provinces. The common factors were constructed using the principal component method of exploratory factor analysis and confirmatory factor analysis. The influence of the competency characteristics on the working performance was analyzed using regression equation analysis. Results The Cronbach 's alpha coefficient of the questionnaire was 0.974. The model consisted of 9 dimensions and 59 items. The 9 competency dimensions included basic public health service ability, basic clinical skills, system analysis capability, information management capability, communication and cooperation ability, occupational moral ability, non- medical professional knowledge, personal traits and psychological adaptability. The rate of explained cumulative total variance was 76.855%. The model fitting index were X2/df 1.88, GFI=0.94, NFI=0.96, NNFI=0.98, PNFI=0.91, RMSEA=0.068, CFI=0.97, IFI=0.97, RFI=0.96, suggesting good model fitting. Regression analysis showed that the competency characteristics had a significant effect on job performance. Conclusion The rural general practitioners competency model provides reference for rural doctor training, rural order directional cultivation of medical students, and competency performance management of the rural general practitioners.
