Objective To investigate the correlations between social support and self efficacy of young and middle-aged patients with peritoneal dialysis. Method The status of social support and self-efficacy of 97 young and middle-aged patients undergoing peritoneal dialysis were investigated and the correlation were analyzed. Results The score on social was (28.0 ± 6.4), lower than the norm (P < 0.01). The score on self-efficacy was (2.38 ± 0.62). The level of confidence was lower in 28 cases (28.9%), high in 58 cases (59.8%), very high in 11 cases (11.3%). The self-efficacy was positively correlated with social support, subjective support and support utilization (all P<0.05). Conclusions The levels of social support and self-efficacy are lower than the norm in young and middle-aged patients undergoing peritoneal dialysis. The self-efficacy is positively correlated with social support including subjective support and support utilization, which indicates that improved social support is effective for the improvement of self-efficacy by providing patients with family and social support.

Objective To investigate the polymorphisms of-139 and -336 nucleotides in dendritic cells specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) promoter region in context of HIV susceptibility, infection routines and HIV/AIDS progress. Methods Polymorphisms of -139 and -336 nucleotides in DC-SIGN were examined in 160 HIV-positive subjects and 178 healthy controls;the Spearman test was performed to analyze their associations with HIV infection status. Results In 160 HIV-positive subjects, there were 92 (57.5%) with-139C, 68 (42.5%) with-139T, 29 (18.1%) with-336C and 131 (81.9%) with -336T. The frequencies of -139T/C and -336T/C in HIV-positive subjects were similar to those in the healthy controls (χ2 =0. 121 and 1. 754, P >0.05 ). No differences were found in the distribution of -139T/C or -336T/C in HIV-positive subjects infected via sex intercourse or intravenous drug (χ2 =0. 435 and 0. 103, P > 0. 05 ). -139C was usually companied with -336C ( r = 0. 359, P < 0.01 ).-139T (27.9%) were more frequently presented in patients with CD4 +T cells ≤50 cells/μL than -139C( 23.0%, χ2 = 4.055, P < 0.05 ). -139T/C and -336T/C were not related to HIV RNA levels ( t = - 0. 643and - 1. 637, P > 0.05). Conclusions Genotype -139C in DC-SIGN promoter region usually coexist with -336C. Polymorphisms of -139 and -336 are not related to HIV susceptibilities or HIV infection routes.-139T genotype may be related to serious depletion on CD4 + T cells.

Objective To investigate the effect of different frequencies of endoscopic ultrasonography (EUS) on diagnosis of duodenal submucesal lesions. Methods A total of 210 elevated duodenal lesions detected by routine endoscopy in 201 patients were examined by EUS at different frequencies according to lesion features and image clarity. Endoscopic resection was applied in 27 lesions with informed consents,and pathological findings were compared with the results of EUS. Results The accuracy of EUS was 81.4% (22/27). Ultrasound of low frequency was superior in displaying overview of lesion and was more suitable for lesions larger than 1.5 cm in diameter or lesions of hyperecho. On the other hand,ultrasound of high frequency was more reliable to reveal minute structures and could be employed in scanning lesions smaller than 1.5 cm in diameter. Combination of different frequencies of ultrasound could provide more details in larger lesions. Conclusion Application of appropriate frequency or combined frequencies of ultrasound in examination of elevated duodenal lesions is beneficial to achieve more accurate diagnosis.

Objective:To explore the relationship between proactive personality, resilience and achievement motivation of military cadets, and to explore the mediating role of resilience between proactive personality and achievement motivation, as well as the moderating effect of cadets’leading ability on this mediating role.Methods:In this study, 109 military cadets were measured with proactive personality scale, Connor-Davidson resilience scale (CD-RISC) and achievement motivation scale. SPSS 26.0 was used for descriptive statistical analysis and correlation analysis.Results:①There was a significant correlation among the total scores of proactive personality, resilience and achievement motivation ( Ps<0.01). ②Proactive personality could significantly predict the level of achievement motivation ( a=0.454, P<0.001), and resilience could significantly predict the level of achievement motivation ( b=0.231, P=0.019). ③Resilience significantly mediated the relationship between proactive personality and achievement motivation ( c′=0.3, P=0.003). ④Cadets' leading ability moderated the effect of resilience on achievement motivation (index=0.338, 95% CI: 0.057 to 0.881). The mediating effect of resilience between proactive personality and achievement motivation was significant for cadets' leaders (Effect=0.381, 95% CI: 0.085 to 1.005), but not significant for other students (Effect=0.043, 95% CI: -0.069 to 0.252). Conclusion:The proactive personality of military cadets can affect the level of achievement motivation through psychological resilience, which is also moderated by cadre identity, suggesting that military education should improve the level of achievement motivation in many ways.

Objective:To investigate the level of psychological stress, anxiety and posttraumatic stress disorder (PTSD) of military medical students under the condition of normalized prevention and control of the epidemic.Methods:A total of 225 students from a military university were selected by random sampling method. Chinese perceived stress scale (CPSS), Perceived social support scale (PSSS), Self-rating anxiety scale (SAS) and PTSD Checklist-5 (PCL-5) were used to measure the mental health of the subjects and influencing factors. SPSS 26.0 was used to conduct independent sample t test and ANOVA analysis. Pearson correlation analysis was conducted, and multiple regression equation was used to further analyze the relationship between psychometric factors. Results:The SAS scores of 22.2% (50/225) of the subjects and PCL-5 scores of 30.7% (69/225) of the subjects reached the positive standard. The results of correlation analysis showed that the total score of PSSS was negatively correlated with CPSS ( r=-0.315, P<0.01), SAS ( r=-0.336, P<0.01) and PCL-5 ( r=-0.137, P<0.05) scores. The score of family support negatively predicted the level of psychological stress ( B=-0.595, P<0.001), anxiety ( B=-0.635, P<0.001) and PTSD level ( B=-0.769, P=0.006) of the students. Conclusion:Social support, especially family support, has a significant protective effect on psychological stress, anxiety and PTSD during the period of normalized prevention and control of the epidemic.
