Objective:To explore the effect of childhood trauma on non-suicidal self-injury and the chain mediating effect of rejection sensitivity and experiential avoidance.Methods:From June 2021 to April 2022, totally 1 130 college students were investigated with childhood trauma questionnaire-short form(CTQ-SF), the tendency to expect rejection scale, acceptance and action questionnaire-2nd edition(AAQ-Ⅱ) and Ottwa self-injury inventory(OSI). SPSS 25.0 and Mplus 8.0 software were used for descriptive analysis, Spearman correlation analysis, structural equation model construction and Bootstrap mediation effect test.Results:Correlation analysis showed that childhood trauma (34.64±8.25), rejection sensitivity (58.02±9.54), experiential avoidance (23.90±7.96) and non-suicidal self-injury (0(0, 1)) were all significantly positively correlated with each other( r=0.163-0.532, all P<0.01). Structural equation model showed that empirical avoidance played a partial mediating effect between childhood trauma and non-suicidal self-injury in college students, with an effect size of 0.045(95% CI=0.013-0.084). Rejection sensitivity and experiential avoidance played a chain mediating effect between childhood trauma and non-suicidal self-injury in college students, with an effect size of 0.017(95% CI=0.005-0.035). Conclusion:Childhood trauma can directly predict non-suicidal self-injury in college students, and it can also indirectly predict non-suicidal self-injury through the partial mediation effect of experiential avoidance and the chain mediation effect of rejection sensitivity and experiential avoidance.

Objective To explore the relationships of subjective well-being with personality trait and self-efficacy in policemen.Methods Totally 329 policemen from 3 prisons were assessed with General Well-Being Schedule (GWBS),Eysenck Personality Questionnaire (EPQ) and General Self-Efficacy Scale (GSES).The relationship between subjective well-being and personality traits,self-efficacy of policemen was analyzed using correlation analysis,variance analysis,regression analysis and structural equation modeling.Results The personality of extroverted stability had the highest score in GSE (2.74 ± 0.56) and GWB (88.89±11.90),while the introverted instability had the lowest(GSE:(2.19±0.46);GWB:(67.38±13.79)).Psychoticism(2.45± 1.72) was negatively correlated with GWB (78.24± 15.32) (r=-0.19,P＜0.01),neuroticism(5.07±3.31) was negatively correlated with GSE (2.50±0.57) and GWB (r=-0.38,-0.60,all P＜0.0l),while introversion-extroversion(8.13±2.86) was positively correlated with GSE and WGB (r=0.26,0.29,all P＜0.01).Structural equation model showed that neuroticism negatively influenced GWB (γ =-0.610,P＜0.01),and introversion-extroversion positively influenced GWB (γ=0.169,P＜0.05).Self-efficacy had partial mediating effect on relationship between neuroticism and GWB as well as the relationship between introversion-extroversion and GWB.Conclusions There is a high correlation between neuroticism and GWB.Self-efficacy plays a mediating role on relationship between personality trait and GWB.It can promote GWB of policemen by enhancing their self-efficacy.

Objective:To explore the relations among childhood trauma,autistic traits and dysexecutive functions in college students.Methods:Totally 2757 college students were assessed with the Childhood Trauma Questionnaire (CTQ).Sixty-three college students were randomly selected as the abused group according to the subscale cutoff point of CTQ Scale defined by Bernstein,and 93 students were randomly selected from students without history of childhood trauma as the control group.They were assessed with the Self-Rating Depression Scale (SDS),Autism Spectrum Quotient (AQ) and Dysexecutive Questionnaire (DEX) to measure depression,autistic traits and abnormality of executive functions,respectively.The individuals from the top and below 27％ of CTQ and AQ scores were defined as higher or lower-level different types of abused group and higher or lower-level autistic traits group,respectively.Results:The differences of DEX scores between higher or lower-level four types of CTQ (emotional abuse,physical abuse,sexual abuse,emotional neglect and physical neglect) and between higher or lower-level autistic traits group were significant (Ps ＜0.05).DEX scores in all higher-level groups were higher than all lower-level groups.Regression analysis showed that DEX score could be positively predicted by scores of emotional abuse,AQ and SDS (β =0.17-0.32,P ＜0.05).SDS score was a mediator between scores of emotional abuse and DEX,and between scores of autistic traits and DEX (95％ confidence interval were 0.05-0.32 and 0.07-0.55,respectively).Conclusion:Childhood trauma and autistic traits may positively predict dysexecutive function,and depression may play a mediating role between emotional abuse and dysexecutive function,and between autistic traits and dysexecutive function.

Objective To explore the difference in demographic variables of the self-esteem of Nanning elderly residents and its relationship with social support,life satisfaction.Methods A sample of 496 elderly lived at Nanning were assessed with self-esteem scale(SES),social support rating scale (SSRS) and life satisfaction index A scale (LISA).Results There were significant differences in overall self-esteem,positive self-esteem and negative self-esteem among different groups of marriage(t=2.209,2.127,-1.839),educational level (t=-2.332,-2.047,2.164),health (F=8.552,3.668,-12.736),economy (F =13.465,14.865,-7.643) and interests(F=8.552,3.668,-12.736) (t=2.860,2.394,-2.785);P＜0.05).Social support (40.13 ± 6.29) could positively predict positive self-esteem (3.04± 0.27) and negatively predict negative self-esteem(2.29±0.23) (β=0.280,-0.195,P＜0.01).Positive self-esteem could positively predict life satisfaction and negative self-esteem could negatively predict life satisfaction(12.58±3.90) (β=0.397,-0.443,P＜0.01).The intermediary effect of positive self-esteem,negative self-esteem between social support and life satisfaction were significantly(P＜0.01).Conclusion Self-esteem has partial intermediary role between social support and life satisfaction.

Objective To investigate the impact of workplace bullying,general self?efficacy,self?es?teem on mental health of nurses. Methods With random sampling,450 nurses from six hospitals in Nanning of Guangxi were selected to complete questionnaire survey.

Objective To evaluate the effect of ditching for drain on the control of the breed of Oncomelania hupensis snails in beaches of Dongting Lake. Methods From November,2009 to November,2012,an O. hupensis snail infested beach of the Yueyang jail and an O. hupensis snail infested beach of Junshan District were selected as research fields in the eastern Dongting Lake area,and the former,as the intervention field,was performed with the ditching for drain by excavators and the latter,as the control field,was not. Results Before the project implemented,the average soil moisture contents on the beaches in dry seasons of the two fields were both about 35.56%. After the project implemented,in the intervention field,the average soil mois?ture content was 26.53%which was significantly lower than that(35.56%)in the control field(F=6.53,P<0.05). The under?ground water levels in different heights in the intervention field were lower than those in the control field (χ2 = 33.33,P <0.05). Before the project implemented,the natural death rates of the snails were 0.98%and 0.89%in the two research fields re?spectively(P>0.05),and after the project implemented(in 2012),no adult and young snails were found in the interventional field,but in the control field,the average densities of living snails and young snails were 29.37 snails/0.1 m2 and 213±108.45 snails/0.1 m2 respectively. Conclusion The intervention of ditching for drain can decrease the soil moisture contents quickly and change the ecological condition,therefore,can control the breed of O. hupensis snails in the beaches of Dongting Lake.

Objective To explore the teaching effect of sandwich teaching in medical psychol-ogy. Methods Totally 101 preventive medicine majors of five-year program were divided into two groups:control group(n=52) and experimental group(n=49). Students in control group were taught by traditional teaching while those in experimental group by sandwich teaching method. Teaching qualities were evaluated by final exam and questionnaire. Exam scores were expressed as x±s and were ana-lyzed by t test. Questionnaine results were expressed as number of people and percentage. Results Scores of experimental group in multiplechoice, case study and final grade (30.347±4.171, 32.031± 2.781, 74.296±5.642, respectively) were better than those of control group (28.520±4.443, 28.760± 4.305, 70.010±7.783, respectively), with significant differences between two groups(P<0.05 for all). But there was no significant difference between two groups in short-answer questions score (11.918± 2.431, 12.731±2.523, respectively)(P>0.05). More than 80.0% students in experimental group thought sandwich teaching improved their communication collaborative capacity , logical thinking ability and problem solving ability, etc. Conclusions With satisfactory teaching effect, sandwich teaching promotes teaching quality.

To summarized the experiences from our basic experimental and clinical research on peritoneal dialysis. In the past 16 years, peritoneal fibrosis rat models and rabbit models of peritonitis were first established successfully in our laboratory in China. Peritoneal mesothelial cells were also separated and identificated. Besides, we assessed the biocompatibility of peritoneal dialysis fluid and analyzed the molecular mechanism of peritoneal mesothelial cell injury. We demonstrated the key role of transforming growth factor-beta1 (TGF-beta1), connective tissue growth factor (CTGF) and peroxisome proliferative activated receptor-gamma (PPAR-gamma) in the pathogenesis of peritoneal fibrosis, as well as their regulation of molecular mechanism. Furthermore, we transfected the plasmids encoding TGF-beta1-shRNA or pCTGF-shRNA into peritoneal cells and tissues by nanocarrier technologies. In clinical research, the positioning of peritoneal dialysis catheters, peritoneal dialysis treatment modalities and the prevention and treatment of its complications were studied. The characteristics and mechanism of solute transport in peritoneal dialysis was also explored.
