Objective To explore the mediating role of personality traits and mental resilience in the relationship between competence and job performance among junior officers.Methods Competency Inventory,25-Item Connor-Davidson Resilience Scale(CD-RISC-25),short version of the Big Five Personality Scale[Neuroticism Extraversion Openness Five-Factor Inventory(NEO-FFI)],and Chinese Perceived Stress Scale(CPSS)were used as assessment tools to survey 586 junior officers selected by convenience sampling.Results ① For junior officers,their competence was positively and moderately correlated with job performance,openness personality,extroversion personality,agreeableness personality,responsibility personality,and total score and score for each dimension of psychological resilience(P＜0.01),and negatively and moderately correlated with neuroticism personality(P＜0.01).② Significantly mediating role was observed in personality and mental resilience for competence and job performance in junior officers,with an indirect effect of 20.68％for personality and 33.18％for mental resilience.Conclusion Personality and mental resilience mediate significantly between competence and job performance in junior officers.Our findings provide a theoretical basis for the action mechanism of competence in job performance for junior officers.

Objective To construct a group psychological training for junior officers based on competency model and explore its intervention effect on competency and mental health of junior officers.Methods Delphi method was used to construct a group psychological training program for junior officers based on competency model.A total of 63 junior officers were subjected with convenience sampling during October and November 2023.According to the principle of randomized controlled experimental design,the participants were divided into experimental group(n=30)and control group(n=33).The experimental group was given our group psychological training program for totally 8 sessions,90～120 min per session,2 sessions per week,while the control group received no such training.Competency scale,12-item general health questionnaire(GHQ-12),Chinese perceived stress scale(CPSS),and Neuroticism Extraversion Openness Five-Factor Inventory(NEO-FFI)were used to assess the 2 groups before and at the end of intervention.Results ① The results of the 2 rounds of expert consultation showed that the total recovery rate was 100％,the expert authority coefficient was 0.87,the Kendall's coordination coefficients(ω)of the 2 rounds of expert consultation were 0.102(P＜0.001)and 0.410(P＜0.001),respectively,with a coefficients of variation of＜0.3,indicating reliable expert consultation.(2)The results of post-intervention time main effect indicated that the total score of competence(P＜0.001),extroversion score(P＜0.05)and responsibility score(P＜0.01)were significantly higher,but the total score of GHQ-12 was obviously lower in the experimental group than the control group(P＜0.001).(3)The results of post-intervention group main effects revealed that the extraversion score of the experimental group was significantly higher than that of the control group(P＜0.01).(4)The results of the post-intervention time × group interaction displayed that the experimental group had notably higher total competency score(P＜0.01),job performance score(P＜0.05),extraversion score(P＜0.05),agreeableness score(P＜0.001)and responsibility score(P＜0.01),but lower total GHQ-12 score(P＜0.01)than the control group.Conclusion Competency-based modeling group psychological training for junior officers can significantly enhance the competency,strengthen the extroversion,agreeableness and responsibility in personality traits,and thus improve job performance for them.

Objective To explore the mediating effect of facial emotion recognition on prosocial behavior of medical students in mask-obscured scenes.Methods Fifty-three medical students from a medical university in Chongqing were enrolled from July to September 2023 to complete the facial emotion recognition task,the dictator gaming task and the state empathy test.Spearman correlation analysis was used to examine the correlation between mask wearing and state empathy,trait empathy and prosocial behaviours,and the PROCESS procedure was used to test the mediation of state empathy and the moderating effect of mask wearing or not.Results ①mask wearing,state empathy and prosocial behaviour were significantly correlated(P＜0.01);② State empathy exerted mediated effect between facial emotion recognition and prosocial behavior,with the largest effect size(47％)for the relative mediating effect of sadness;③The interaction terms of facial emotion recognition and mask wearing had a significant effect on state empathy(P＜0.05).Conclusion Facial emotion recognition can influence prosocial behavior directly and also exert indirect effect on prosocial behavior through state empathy.Compared to the condition without mask wearing,mask wearing can significantly facilitate the effect of happy,sad and neutral emotions on state empathy.

In recent years, group psychological training has become one of the most important skills that must be mastered by psychological workers in colleges and universities. However, there are problems with its teaching models, such as unreasonable course content, insufficient autonomous practice, and the lack of teaching competency assessment. Based on the theory of modules of employable skills (MES), we have constructed the core modules of group psychological training on teaching course content and skills, and in accordance with the BOPPPS teaching model, we have achieved satisfying teaching effects though the teaching practice of "bridge-in-theory and discussion-teaching practice and supervision-effectiveness assessment and summarization", in which the trainees have made objective progress in theory application, scheme design, and skill practice, with a high degree of subjective self-satisfaction. According to the problems found in the teaching practice, we will further improve the model by optimizing the modules, innovating teaching implementation methods, refining competency assessment standards, and strengthen the overall integration with medical education in order to better meet the needs of the development of psychological service in colleges and universities.

Objective:To explore the imaging features and clinical effect of accordion maneuver in promoting the bone healing at the docking site after tibial transport under ultrasonic monitoring.Methods:Retrospective analysis was conducted on the clinical data of 16 patients with tibial bone transport who were admitted to the Department of Orthopedics, the second Hospital of Shanxi Medical University from May 2018 to October 2019. All the patients were treated with accordion maneuver to promote bone healing at the docking site under ultrasound monitoring. There were 14 males and 2 females, aged (45.3±14.3) years (range: 6 to 61 years). Before tibial bone transport, the length of the tibial defect of 16 patients was (6.0±2.6) cm (range: 2.0 to 12.1 cm). The operation steps of accordion maneuver were as follows: pressurization for 2 weeks, suspension for 12 days, distraction for 2 weeks, retraction for 2 weeks, and then stop the operation to consolidate the bone mineralization. During accordion treatment, ultrasound was used to monitor the size of hematoma, Adler grade of blood flow signal and the changes of new callus in and around the docking site. X-ray was performed to monitor bone healing at the docking site. Pearson correlation coefficient was used to analyze the correlation between the size of hematoma, the resistance index of blood flow signal and the bone healing time of the docking site. Paley healing criterion was used to evaluate the bone healing and functional recovery of the patients.Results:During accordion maneuver, ultrasound examination showed that the Adler grade of blood flow signals around the docking site increased gradually before retraction and then decreased gradually, but the degree of callus mineralization continued to increase gradually. After 2 weeks of pressure on the docking site, hematoma was observed in 14 patients by ultrasound examination. X-ray showed that all docking sites had bony healing, with the healing time of (30.8±4.9) weeks (range: 23 to 40 weeks).The size of the hematoma was negatively correlated with the healing time of the docking site ( r=-0.819, P<0.01). No hematoma was found in 2 patients, and after continuous observation for 20 weeks, there was still no obvious callus connection at the docking site. After bone cortical removal, ultrasound examination showed hematoma formed at the docking site. Accordion maneuver was continued, and the docking site healed at 30 and 32 weeks after surgery, respectively. There was a negative linear correlation between hematoma size at 2 weeks of compression and the blood flow resistance index at 2 weeks of retraction in 16 patients ( r=-0.801, P<0.01). The patients were followed-up for (14.5±3.2) months (range: 10.6 to 20.2 months). At the last follow-up, 12 patients were evaluated as excellent and 4 were evaluated as good by Paley healing criteria. Conclusion:The distraction and compression stress applied in accordion maneuver can promote bone healing at the docking site, and ultrasound can monitor early signs of bone healing at the docking site to help determine the tendency of bone healing.

Objective To investigate early diagnosis and treatment of Paget disease of breast. Methods The clinicopathological data of 26 cases of breast Paget disease in the First Affiliated Hospital of Wenzhou Medical University from January 1995 to June 2018 was analyzed. Results The main clinical manifestation of 26 patients was eczema like papillae in 19 cases (73.1%), and associated with nipple discharge in 9 cases (34.6% ) and breast mass in 6 cases (23.1% ). The diagnosis of this disease was based on curettage cytology in 4 cases (15.4% ), biopsy in 8 cases (30.8% ), and needle aspiration cytology or post resection pathological examination in 14 cases (53.8% ). Paget disease consisted of simple papillary Paget disease in 3 cases (11.5%), ductal carcinoma in 18 cases (69.2%) and invasive ductal carcinoma in 5 cases (19.2%). Pathological TNM staging was 0 stage in 19 cases (73.1%), stageⅠin 3 cases (11.5%), stageⅡin 2 cases (7.7%), stageⅢin 2 cases (7.7%) and no stage inⅣcase. In this group, 2 cases underwent radical mastectomy, 18 cases underwent modified radical mastectomy, 4 cases underwent simple mastectomy, and 2 cases underwent mastectomy combined with low axillary lymph node dissection and intraoperative rapid frozen examination. Fourteen patients received adjuvant chemotherapy with CEF(cyclophosphamide + pharmorubicin + tegafur)/EC (pharmorubicin + cyclophosphamide) + T(docetaxel) or TP(docetaxel + cis- platinum)regiment after operation, 2 cases were treated with trastuzumab targeted therapy and 5 cases with adjuvant radiotherapy. Twenty-five of 26 patients were followed up for 8-108 months except one patient lost in follow-up. The 5-year survival rate was 96.0% (24/25), and the 10-year survival rate was 52.0% (13/25). Conclusions The diagnosis of Paget disease of the breast depends on cytology or pathology, and multidisciplinary treatment based on surgery is judged of by tumor stage and coincident other types of breast cancer and axillary lymph node involvement.

Objective To evaluate the accuracy of different noninvasive methods for the diagnosis of nonalcoholic steatohepatitis(NASH) and hepatic fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) combined with type 2 diabetes mellitus(T2DM). Method A prospective comparative study was performed for 91 patients with T2DM and NAFLD, which were diagnosed by glucose tolerance test and liver biopsy. The height and body mass of the patient were measured, and the body mass index(BMI) was calculated. The fasting venous blood of the patient was collected, and then the blood routine, liver function and ferritin were measured. NPS, neutrophil lymphocyte ratio(NLR), BARD score, FIB-4 index, APRI, and NAFLD fibrosis score(NFS) were calculated. All patients underwent transient elastography (Fibrotouch) to evaluate the degree of liver stiffness measurement (LSM) and controlled attenuation parameter. All the liver biopsy specimens were categorized by SAF as the gold standard for evaluating NASH and liver fibrosis NASH. Correlation analysis was applied to compare the correlation between the noninvasive methods and SAF. The receiver operating characteristic (ROC) curve and the area under the curve (AUC) were used to assess the diagnostic value of the noninvasive methods for NASH and liver fibrosis NASH. Results In T2DM combine with NAFLD patients, NPS, LSM, NFS, APRI, FIB4 and BMI scores were positively correlated with SAF (r value was 0.509, 0.508, 0.252, 0.396, 0.313 and 0.213, respectively; P value was <0.001, <0.001, 0.016,<0.001, 0.003 and 0.043, respectively). LSM, NPS, NFS and FIB4 scores were positively correlated with liver fibrosis (r value was 0.535, 0.337, 0.315 and 0.315, respectively; P value was <0.001, 0.001, 0.002, 0.002, respectively). The ROC curve shows that the area under the curve of NPS, LSM, APRI, FIB4 and BMI for diagnosing NASH was 0.838, 0.760, 0.734, 0.623 and 0.682, respectively, and P value was 0.000, 0.000, 0.000, 0.044 and 0.003, respectively. For the diagnosis of fibrotic NASH, that value of LSM, NFS, FIB4 and NPS was 0.795, 0.765, 0.686 and 0.623, respectively, and P value was 0.000, 0.001, 0.020 and 0.123, respectively. Conclusions NPS, LSM and APRI have good clinical diagnostic value for NASH. LSM and NFS have good diagnostic value for fibrotic NASH.

Objective: To investigate the effect of dietary control combined with different exercise modes on plasma vaspin, irisin, and metabolic parameters in patients with non-alcoholic fatty liver disease (NAFLD) through a randomized open parallel-controlled study. Methods: The patients aged 30-65 years who visited Tianjin Third Central Hospital from January 2013 to December 2014 and were diagnosed with NAFLD by liver ultrasound and fat content determination were screening, and 474 patients were enrolled in this randomized controlled trial and divided into aerobic exercise group, resistance exercise group, and control group. All patients received dietary intervention. The three groups were compared in terms of biochemical parameters, fat content, NFS score, energy metabolic parameters, body composition index, and levels of vaspin and irisin at baseline and after 6 months of intervention. SPSS 19.0 was used for statistical analysis. The t-test, the Mann-Whitney U test, the chi-square test, and an analysis of variance were used for comparison between groups. The multiple imputation method was used for missing data, and the results were included in the intention-to-treat analysis. Results: There were no significant differences in age, sex, anthropometrical parameters, and biochemical parameters between the three groups at baseline. Compared with dietary control alone, aerobic exercise and resistance exercise helped to achieve significant reductions in waist circumference, diastolic pressure, percentage of body fat, volatile fatty acid, fasting blood glucose, homeostasis model assessment of insulin resistance, triglyceride, low-density lipoprotein cholesterol, free fatty acid, uric acid, alanine aminotransferase, and liver fat content after 6 months of intervention (P < 0.05). The aerobic exercise group had a significant increase in non-protein respiratory quotient and significant reductions in body mass index and aspartate aminotransferase after intervention, as well as a significant increase in resting energy expenditure and significant reductions in abdominal fat ratio and total cholesterol after 6 months of resistance exercise (P < 0.05). The aerobic exercise group and the resistance exercise group had a significant reduction in vaspin and a significant increase in irisin after intervention (P < 0.05), and the resistance exercise group had significantly greater changes in these two adipokines than the aerobic exercise group (P < 0.05). Conclusion Exercise therapy is an effective method for the treatment of metabolism-associated diseases, and a combination of resistance and aerobic exercises is more reasonable and effective in clinical practice. As a relatively safe exercise mode, resistance exercise can also effectively improve the metabolic state of NAFLD patients.
