Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5% of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P<0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score > 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P < 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1% of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2%of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.

BACKGROUNDUlcerative colitis (UC) is associated with differential expression of genes involved in inflammation and tissue remodeling. MicroRNA (miRNA) plays an important role in the pathogenesis of UC by regulating the gene expression at the post-transcriptional level and control crucial physiological processes. This study aimed to identify aquaporin 8 (AQP8) expression and its relationship with miRNA in UC patients.
METHODSHuman colon samples, in this study, were obtained from 20 patients with UC and 16 healthy subjects undergoing diagnostic colonoscopy at the Chinese People's Liberation Army General Hospital between December 2009 and June 2010. We screened different genes from UC tissues and healthy subjects using genome-wide microarray, quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blotting. Regulation of gene expression by miRNAs was assessed by luciferase reporter construct assays and transfection of specific miRNA mimics and inhibitor.
RESULTSWe identified that 1596 genes were increased and 1301 genes were decreased in UC patients compared to healthy subjects. Among them, we focused on the analysis of AQP8 which was decreased three folds in UC tissues (P < 0.01). The expression of AQP8 mRNA and protein were decreased in UC tissue and tumor necrosis factor (TNF)-α treated HT29 cells compared with controls (P < 0.05). We searched candidate target miRNAs of AQP8 through bioformatics and the luciferase report assay analysis indicated that miR-424, miR-195, miR-330, miR-612, and miR-16 which has complementary site in the 3-untranslated region (3'UTR) of AQP8 could decrease the relative luciferase activities by 10% - 45%.
CONCLUSIONAQP8 and its relationship with miRNAs may be involved in the pathogenesis of UC.
