Objective To explore the status and influencing factors of posttraumatic growth (PTG) in breast cancer patients and identify the influence of cognitive appraisal on PTG and the relationship between PTG and cognitive appraisal. Methods A cross-sectional study was conducted. Totally 356 breast cancer patients were investigated with the revised Posttraumatic Growth Inventory (PTGI), the Cognitive Appraisal Scale. Results The average score of PTG in breast cancer patients was (55.06±14.36) points. There were significant differences between different education level and health-care payment patients in the total score of PTG (t=5.886, 5.154, P<0.01). The level of PTG was correlated with the patients′ cognitive appraisal way. It was negatively correlated with uncertain appraisal about disease and threat appraisal,and positively correlated with positive appraisal and responsible appraisal. The main prediction factors for PTG were positive appraisal, uncertain appraisal about disease, responsible appraisal, health-care payment and education level. All the variables could explain 42.7% variance of PTG. Conclusions Breast cancer patients in this study report moderate level of posttraumatic growth. The level of PTG in breast cancers is influenced by variables of patients′ education level, health-care payment and cognitive appraisal. Cognitive appraisal could predict the development of PTG significantly.

Objective To investigate the function and clinical significance of nuclear matrix binding region binding protein 1(SATB1)and epidermal growth factor receptor(EGFR)in gastric cancer.Methods The expression of SATB1 and EGFR was detected by immunohistochemistry in 60 cases of paraffin-embedded gastric cancer and 39 cases of gastric mucosal inflammation.Small interfering RNA(siRNA)was transfected into gastric cancer cells.The expression of SATB1 and EGFR after transfection was detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction(RT-qPCR)and Western blot.The cell migration and invasion changes of MGC803 after transfection were detected by cell scratch test and Transwell test.The prognosis of gastric cancer pa-tients with different SATB1 and EGFR expression was analyzed by KM survival analysis.Results The expression of SATB1 and EGFR in gastric cancer tissues was higher than that in gastric mucosa inflammation tissues,and the difference was statistically significant(P＜0.05).The expression of SATB1 was correlated with lymph node metas-tasis and distant metastasis of gastric cancer,and the difference was statistically significant(P＜0.05).EGFR ex-pression was also associated with distant metastasis,and the difference was statistically significant(P＜0.05).There was a positive correlation between the expression of SATB1 and EGFR in gastric cancer tissues(r=0.49,P＜0.05).RT-qPCR and Western blot showed that siRNA could effectively knock down the expression of SATB1 and EGFR in gastric cancer cells.The results of cell scratch and Transwell experiments showed that the migration and invasion of gastric cancer cells were inhibited by knocking down SATB1 and EGFR.The results of KM survival curve showed that gastric cancer patients with low expression of SATB1 had a better prognosis,while those with low expression of EGFR had a better prognosis.Conclusion The expression levels of SATB1 and EGFR are closely re-lated to lymph node metastasis and distant metastasis of gastric cancer,and decreasing the expression levels of SATB1 and EGFR can inhibit the migration and invasion of gastric cancer.

The construction of "New Medicine" is the leader of the innovative development of medical education in China in the new era. Strengthening the cross-integration of medicine and science is helpful to promote the training of top-notch interdisciplinary innovative talents under the multidisciplinary background of "Medicine + X". The applied psychology major in medical colleges has unique advantages in education and teaching resources. How to combine the advantages to construct the education model of the integration of medicine and science is still in the exploration stage. This paper analyzes the current situation of talent training of the applied psychology major in medical colleges and the new requirements for discipline-major construction under the background of "New Medicine" construction, demonstrates the measures to strengthen the deep integration of medicine and science from the aspects of curriculum system setting, teacher team construction, practice teaching, and teaching method reform, and puts forward the innovative education model of the integration of medicine and science in applied psychology-medicine interdisciplinary training.

Objective:To compare and analyze the correlation between two kinds of point-of-care testing (POCT) instruments and Roche electrochemiluminescence instrument in detecting myocardial biomarkers,so as to provide reference for the selection of POCT instruments in clinical testing. Methods:A total of twenty patient's samples were selected,which concentration range covered the reportable range of detection results. Two kinds of POCT instruments (named respectively A and B) were used to detect the concentrations of plasma myoglobin (Myo),creatine kinase isoenzyme mass (CK-MB mass),cardiac troponin I(cTnI),and N-terminal fragment of B-type natriuretic peptide (NT-proBNP)/Brain natriuretic peptide (BNP). The results of the electrochemiluminescence instrument were used as reference,and Pearson correlation analysis and Kappa test evaluation were used to evaluate respectively the correlation and consistency of the detected results between the two kinds of POCT instruments and Roche electrochemiluminescence instrument. Results:Our study demonstrated that there were good correlations in the detected results of Myo,CK-MB mass,cTnI,NT-proBNP/BNP between the instrument A and Roche electrochemiluminescence instrument,and between the instrument B and Roche electrochemiluminescence instrument (rinstrumentA=0.994,0.989,0.917,0.996,rinstrumentB=0.928,0.934,0.883,0.977,P<0.05),respectively. In the comparisons about consistencies,the concordance rates between instrument A and electrochemiluminescence instrument were respectively 90％,100％,70％ and 100％ in detecting Myo,CK-MB,cTnI and NT-proBNP,and the concordance rates between instrument B and electrochemiluminescence instrument were respectively 90％,100％,70％ and 100％ in detecting them. Both two kinds of POCT instruments had favorable consistencies with Roche electrochemiluminescence instrument (Kappainstrument A=0.798,1.00,0.429,1.00,Kappainstrument B=0.794,0.886,0.429,1.00),respectively. The precisions of both instruments were less than 10％. Conclusion:Both two kinds of POCT instruments can meet the requirements of clinical test,which have favorable correlations with electrochemiluminescence instrument in detecting myocardial biomarkers.
