Objective To explore the effects of military operation types on the mental health of Chinese veterans and the mediating role of psychological quality based on a dual-factor model of mental health.Methods Cross-sectional study design was adopted in this study.Self-designed demographic information questionnaire,patient health questionnaire depression module-9 item(PHQ-9),general anxiety disorder-7(GAD-7),satisfaction with life scale and psychological quality questionnaire were used to survey on 3 027 Chinese veterans.Results ① Compared to the one-factor model and the two-factor models with other indicators,the dual-factor model of mental health,with anxiety symptoms as a negative indicator and life satisfaction as a positive indicator,fitted better(Chi-square/df=8.927,GFI=0.974,AGFI=0.962,RMSEA=0.051,NNFI=0.985,IFI=0.988,CFI=0.988).②Taking the subjects who did not participate in war/non-war military operations as the reference,psychological quality showed significant relatively mediating effects between war and life satisfaction,and between war and anxiety symptoms(P＜0.05),while no such significances were observed in the corresponding ones for non-war military operations.③ War could decrease veterans'life satisfaction through full mediation of cognitive,adaptive and personality dimensions of psychological quality,and increase anxiety symptoms through partial mediation of the personality dimension of psychological quality.Conclusion The dual-factor model of mental health is applicable to Chinese veteran population,and psychological quality plays a mediating role between war and mental health.

Objective To explore the features of sleep quality and its relationship with perceived stress and occupational stress in military personnel serving in high-altitude regions.Methods Cross-sectional study design was adopted in this study.In February 2023,self-designed demographic data questionnaire,Pittsburgh sleep quality index(PSQI),perceived stress scale(PSS-10)and job content questionnaire(JCQ)were applied to survey 3 784 soldiers from a unit stationing in plateau subjected by cluster sampling.Results The total score of PSQI was 5.37±2.78 in the participants,and the total score and the scores of each dimension of PSQI were significantly higher than the national norms for Chinese(P＜0.001).There were significant differences in PSQI scores among different age,length of military service,nationality,length of stationing in plateau,education level and family structure(P＜0.001).The low perceived stress group had significantly lower PSQI scores than the high perceived stress group(t=-12.108,P＜0.001).Regulatory effect analysis showed that the length of stationing in plateau,work autonomy,work psychological requirements,and social support in the work environment could modulate the relationship between perceived stress and sleep quality(t=8.326,-3.788,-2.145,-6.656,P＜0.05),and explained 14.6％,7.6％,7.0％and 7.9％of the variance of sleep quality,respectively.Conclusion The military personnel serving in high-altitude regions have a poor sleep quality.Age,time of military service,time of stationing in plateau,nationality,family structure,education level,perceived stress,and occupational stress are important factors affecting their sleep quality.The length of stationing in plateau time and occupational stress,can modulate the relationship between perceived stress and sleep quality.

Objective:To investigate the feasibility of multipoint core needle biopsy (CNB) at mid-stage to predict the treatment effect of neoadjuvant systemic therapy for breast cancer.Methods:A total of 67 breast cancer cases with indications of neoadjuvant systemic therapy were selected from Mar. 2021 to Nov. 2022.In the fourth cycle of neoadjuvant systemic therapy, core needle biopsy was performed at 3, 6, 9, 12 points of tumor bed and residual tumor foci of breast respectively.The results of CNB were compared with the results of routine pathology of surgery after the completion of neoadjuvant therapy. Matched biopsy and surgical specimens were compared to assess pCR. The accuracy and false negative rate (FNR) of interim pathological assessment were analyzed. The coincidence probability of interim biopsy pathology and pathology of standard surgical excision was verified.Results:The median age of enrolled patients was 49.2 years (21-69 years) .Median maximum tumor diameter before neoadjuvant systemic therapy and residual tumor diameter after neoadjuvant therapy were 40.4 mm (range 21-93mm) and 19.6 mm (range 0-41mm) respectively. A total of 28 patients achieved pCR, and the PCR rates of hormone receptor-positive and HER2-nagative,triple-negative,hormone receptor negative and HER2-positive and hormone receptor-positive and HER2-positive disease were 4/24 (16.7%) ,6/14 (42.9%) ,11/18 (61.1%) ,7/11 (63.6%), respectively. Two cases had no preoperative imaging abnormalities. The results of core needle biopsy pathology of residual tumor lesions in 55 patients were consistent with those of routine post-operation pathology.The results of core needle biopsy pathology of tumor bed of 56 patients was consistent with the routine pathology of surgery. The false negative rate of interim multipoint biopsy pathology of residual tumor foci was 17.9% (12/67). The false negative rate of tumor bed with core needle biopsy was 5.9% (4/67) .Conclusions:CNB guided under ultrasound is feasible in predicting tumor retreat situation in the tumor bed area and residual tumor foci at mid-stage of neoadjuvant therapy. Increasing the number of core needles and improving biopsy techniques may improve the accuracy of pathological evaluation of interim multipoint biopsy.

Background According to China's Labor Statistics Yearbook 2020, there were 113293 work-related injuries and 25092 work-related deaths in 2019. It is of great significance to enhance the courage quality of high-risk workers for the maintenance of personal health and the effectiveness of organizational work. Objective To revise the Physical Courage at Work Scale (PCWS) for its application in Chinese employees exposed to high-risk workplace. Methods A total of 1280 high-risk workers completed the revised PCWS for Chinese employees. Item analysis and exploratory factor analysis were used to analyze the scale's construction validity. Confirmatory factor analysis was used to verify the results of exploratory factor analysis, Cronbach's α coefficient was used to verify the reliability of the scale, Pearson correlation analysis of the scale with Mental Quality Questionnaire for Armymen (MQQA) and Norton Courage Measure (CM) was used to verify the validity of the revised PCWS, and Pearson correlation analysis was used to determine the discrimination for each factor of the revised PCWS. Results The results of item analysis showed that the correlation coefficients between the scores of all items and the total score of the revised PCWS were greater than 0.4. The exploratory analysis indicated that there were five factors including immediate danger,providing for family, confronting other's aggression, reporting violations, and contributing to society in the revised version. The confirmatory analysis indicated the five-factor model fitted well (minimum fit function Chi-square/degree of freedom, CMIN/DF=4.60; normed fit index, NFI=0.93; comparative fit index, CFI=0.95; incremental fit index, IFI=0.93; standardized root mean square residual, SRMR=0.05; root mean square error of approximation, RMSEA=0.07). The internal consistency coefficient of the revised PCWS was α=0.95. The correlation coefficients of the revised PCWS with MQQA and CM ranged from 0.11 to 0.28 (P<0.01), and the correlation coefficients between factors of the revised scale ranged from 0.35 to 0.72 (P<0.01). Conclusion The revised PCWS has good reliability and validity in Chinese employees.

Objective To examine the adaptability of Carver and White' s behavioral activation/in-hibition scales(BIS/BAS Scales)in a large sample of Chinese military-man,and to revise the instrument and validate its factor structure. Methods A total of 2 921 Chinese military-men completed four subscales:one for the Behavioral Inhibition System,and three for the Behavioral Approach System(drive,reward re-sponsiveness,fun seeking).Data were analyzed using exploratory and confirmatory factor analysis.The internal consistency of the subscales and the complete scale were examined. Results The findings did not support Carver and White's 4-factor structure which was validated in a sample of Chinese college students.A 3-factor structure(behavioral inhibition,reward responsiveness,drive)in Chinese military-man were extracted and validated using confirmatory factor analysis(CFA)(KMO=0.87,CFI=0.94,RMSEA=0.06).The Cronbach α of behavioral inhibition,drive and reward responsiveness were 0.78,0.71 and 0.67 respectively.The internal consistencies of behavioral inhibition and drive were higher than four-factor model of Chinese college students and the internal consistencies of drive and reward responsiveness were less than American young adults.Be-havioral inhibition and drive positively predicted depressive symptoms(βBIS=0.332,βDrive=0.076,P<0.001),and reward responsiveness negatively predicted depressive symptoms(βRRS=-0.140,P<0.001). Conclusion The BIS/BAS Scales(revised Chinese military version)has acceptable reliability and validi-ty,and can be utilized as a measurement tool for assessing the approach/avoidance motivation of Chinese ser-vicemen.

Objective To investigate the effect of chaihu-shugan-san ( CSS) on the behaviors and Notch1 signal pathway in depression model rats. Methods Thirty-two SD rats with similar behavioral scores were divided into control group (CON),model group (CUMS),positive control group (FLU) and interven-tion group (CSS).The depression model was established by stimulating with chronic unpredictable mild stress (CUMS),and the behaviors evaluation was assessed by sugar water consumption and forced depression.Im-munofluorescence was used to detect the proliferation of hippocampus neurons in rats,at the same time,real- time PCR and Western blot were used to detect the mRNA and protein expression levels of each factor (Notch1,Hes1,Hes5 and Jagged1) of Notch1 signal pathway respectively. Results Compared with CON group,the percentage of sugar water preference and swimming length of rats decreased significantly in CUMS group (P＜0.05 and P＜0.01).Compared with CUMS group,the percentage of sugar water preference and swimming length of rats increased significantly in CSS group(P＜0.05).Compared with CON group,there was a significant increase in the inactivity length of rats between CUMS group,FLU group and CSS group,and the difference was statistically significant (P＜0.01).Compared with CUMS group,the swimming length of rats in CSS group was significantly reduced,and the difference was statistically significant (P＜0.01).Compared with CON group((750.00±27.51)/mm2),the number of BrdU positive cells in the substratum or granulocyte lay-er of the hippocampus dentate gyrus of rats in CUMS group ((338.75±29.61)/mm2),FLU group ((545.00 ±17.73)/mm2) and CSS group ((529.38±13.74)/mm2) was significantly reduced(P＜0.01).Compared with CUMS group ((338.75±29.61)/mm2),there was a significant increase in the number of BrdU positive cells in the substratum or granulocyte layer of the hippocampus dentate gyrus of rats in CSS group ((529.38 ±13.74)/mm2),and the difference was statistically significant (P＜0.01).Compared with CON group,the mRNA and protein expression levels of Notch1,Hes1,Hes5,and Jagged1 in the hippocampus of rats in CUMS group were significantly reduced(P＜0.05 or P＜0.01).Compared with CUMS group,the mRNA and protein ex-pression levels of Notch1,Hes1,Hes5 and Jagged1 in the hippocampus of rats in FLU group and CSS group were significantly increased,and the differences were statistically significant (P＜0.05 or P＜0.01). Conclu-sion Notch1 signal pathway may be related to the obstacle during the hippocampus nerve regenerating in the model rat under chronic unpredictable mild stress.CSS may play an anti-depressant role by regulating Notchl to improve hippocampus nerve regeneration.

Medical psychology master's degree graduate student course mainly includes basic cour-ses, professional courses and psychological skills training, professional practice skills learning and scientific research quality training. Due to the constraints of discipline development starting late, teachers being rela-tively weak and other objective factors, in curriculum setting, there exist problems of unclear objectives, confusing the primary with secondary, unclear standard, lacking principles, and in particular, there are obvious deficiencies in the training and cultivation of students' ! professional skills . Based on the above objective problems, we made preliminary discussion on the training objectives, the main problems, curricu-lum setting, assessment standards and principles to follow, in order to achieve the purpose of cultivating high-level application-oriented talents through curriculum design and teaching practice.

Objective To understand the status of the academy graduate students' psychological pressure.Method The team used cluster random sampling method 5 times in 2015,Life Scale (LES) of the classic life event scale (event) was used to make investigation into graduate students of the different professional background in 8 universities,and recovered 1041effective questionnaires.SPSS 18.0 statistical method was applied to study the life events category,occurrence frequency and so on to make the analysis of variance (95％ confidence interval).Results According to the classification of events,the total score of work study class was the highest,the lowest was social and other categories,family class was centered,and the difference was statistically significant (F=21.987,P=0.000).According to the frequency of events,there were four life events whose mean intensity achieved the severe (2.5),that was,work and study pressure,love/engagement,family economic difficulties,the beginning of employment.There were 23 events whose intensity means reached moderate (1.5-2.5),such as husband and wife separation due to work,children's discipline difficulties,family members being seriously ill or seriously injured,etc.The rest were mild events (＜ 1.5).Conclusion At present,China's military academy graduates have obvious psychological pressure,mainly coming from work,school,family,marriage,economic,human relations,employment,etc.It is suggested that psychological intervention from multi channels should be made to improve the pressure of the current situation.

Objective:To translate the Attention to Positive and Negative Inventory(APNI)and analyze the validity and reliability in Chinese undergraduates sample,to offer a convenient and reliable tool of measuring the cognitive bias for national researchers. Methods:The English-version APNI went through translation into Chinese, retroversion into English,translation into Chinese again,and revision several stages. Two parts of samples (1450 Chinese college students)were surveyed. Sample one (n=1000)was used for item analysis,exploratory factor a-nalysis (EFA),concurrent validity and reliability analysis,while sample 2 (n=450)was used for confirmatory fac-tor analysis (CFA). Totally 68 subjects of sample 1 were randomly chosen and resurveyed with an interval of one week. Beck depression inventory (BDI-II)and patient health questionnaire (PHQ-9)was used for concurrent validi-ty. Results:Item analysis indicated that the 22 items of Chinese APNI had good discriminability. EFA focused onattention to positive information(API)and attention to negative information(ANI)two factors. CFA showed good model fit (χ2 =1376,RMESA=0. 09,CFI=0. 94). Concurrent validity result showed that the total scores of BDI-II and PHQ-9 was negatively correlated with total scores of API (r=-0. 24,-0. 29,Ps<0. 01 ),and posi-tively correlated with total scores of ANI (r=0. 36,0. 31,Ps<0. 01). The Cronbach'αcoefficients of API and ANI sub-scale were 0. 86 and 0. 82,while the retest reliability coefficients were 0. 79 and 0. 62. Conclusion:It suggests that the Chinese APNI has good validity and reliability in a sample of college students,which could be used to eval-uate the cognitive bias of Chinese college students.

Objective To provide references for the plan-making of mental intervention on new recruits through the exploration of the comprehensive psychological behavior training influences on psychological stress and health and relevant factors.Methods 436 new recruits in training period were divided into comprehensive psychological behavior training group (intervention group) and non intervention group (control group).By randomly selected 2 (intervention group,control group) × 2 (Before training and after training) matching design,the questionnaire survey was carried out using stress-reaction questionnaire (SRQ),symptom checklist 90 (SCL-90),eysenck personality questionnaire(EPQ),trait coping style questionaire(TCSQ) at the 15th day and 75th day.t-test between group and matched t-test within group and multiple stepwise regression analysis were carried out.Results (1) The SCL-90 total point of new recruits in intervention group (125.26±36.52)and control group(124.92± 34.79) before the training and the difference of SRQ and TCSQ factor scores had no statistical significance(P＞ 0.05).The difference after the comprehensive psychological behavior training had no statistical significance (P＞ 0.05) as the total points of SCL-90 of intervention group(125.63±36.74) and other factors' score were compared with before.Except for the somatization and force,the total points of SCL-90 (131.21 ± 39.98)and other factor scores of the control group were all higher than what they were in the early period of the training significantly (P＜ 0.01 or P＜0.05).In the later period of group training,from the parallel controlled study among groups we found that except for the somatization and force,the total points of SCL-90 and other factor scores of the control group are all lower than the control group (P＜0.0 or P＜0.05).(2)The total points of intervention group's SCL-90 and SRQ had significant positive correlation with negative coping and stability(r=0.313-0.698,P＜0.01) while it had negative correlation with introversion and extroversion(r=-0.293--0.207,P＜0.01) as well as dissimulation at the later period of group training,however,it did not have significant correlation with positive coping method (P＞0.05).(3) The regression analysis showed that factors significantly affected the total score of SCL-90 respectively was:SRQ total score,negative coping method,stability,introversion-extroversion and psychoticism (P＜ 0.01).Five variables'coefficient of determination R 2 =0.665,F=247.82,P＜ 0.01.Conclusion The comprehensive psychological behavior training could reduce the over psychological stress of new recruits,promote their positive coping attitude and protecting their psychological health.Coping method and personality characteristics are important mediating variable between new recruits' psychological stress and mental health.
