Objective:To explore the relationship between resilience and psychological distress among female college students with left-behind experience, and the role of cognitive reappraisal and stress perception in it.Methods:From May to June 2020, a total of 4 008 female college students with experience of being left-behind were sampled by the whole group sampling method. All participants were evaluated by the Connor-Davidson resilience scale, the cognitive reappraisal scale of the emotion regulation questionnaire, the stress perception scale-10 and Kessler psychological distress scale. The PROCESS macro program of SPSS 25.0 was used to test the mediating effect of cognitive reappraisal and the moderating effect of stress perception.Results:(1) The measure of psychological distress showed that the detection rate was 13.46% for male college students with left-behind experience, 12.93% for male college students without left-behind experience, and 11.40% for female college students with left-behind experience and 9.26% for female college students without left-behind experience.(2) The scores of cognitive reappraisal, stress perception and psychological distress for female college students with left-behind experience were significantly different in terms of grade level ( F= 3.52, 3.54, 3.49, all P<0.05). (3) Resilience(58.39±13.64) showed a significant positive correlation with cognitive reappraisal(31.28±5.09) ( r=0.51, P<0.001) and a significant negative correlation with stress perception(16.42±5.49)and psychological distress(21.62±7.76)( r=-0.41, -0.30, both P<0.001). Cognitive reappraisal showed a significant negative correlation with stress perception and psychological distress ( r=-0.33, -0.27, both P<0.001). Psychological distress showed a significant positive correlation with stress perception ( r=0.67, P<0.001). (4)Stress perception played a moderating role between cognitive reappraisal and psychological distress. The effect of cognitive reappraisal on psychological distress was not significant under low levels of stress perception( βsimple=-0.01, P=0.52). Under high levels of stress perception, cognitive reappraisal had a significant negative effect on psychological distress( βsimple=-0.08, P<0.001). Conclusion:Resilience of female college students with left-behind experiences can directly affect psychological distress or indirectly through cognitive reappraisal, and this mediating model is moderated by stress perception.

Objective:To explore the relationship between childhood emotional trauma and loneliness in the college students and the role of basic psychological needs and positive coping style.Methods:A total of 11 295 col-lege students were assessed with the UCLA Loneliness Scale,Emotional Neglect and Emotional Abuse Question-naire of the Childhood Trauma Questionnaire,Basic Psychological Needs Scale,and Positive Coping Style Question-naire of the Simple Coping Style Questionnaire.Mplus 8.3 was used to analyze the mediating effect and the moder-ated mediating effect based on structural equation,and the non-parametric Bootstrap method was used to test the mediating effect.Results:The childhood emotional trauma was positively correlated with college students'loneli-ness(γ=0.61,P＜0.001).Basic psychological needs partially mediated the relationship between emotional trauma and loneliness(95％CI:0.45-0.49).Positive coping styles significantly moderated the first half of the path(γ=-0.10,P＜0.001)and the direct path(γ=0.05,P＜0.001)of the mediation model.Conclusion:College students'loneliness is associated with childhood emotional trauma and it is partially mediated by basic psychological needs,with positive coping playing a moderating role.

Objective To investigate the effect of iTBS stimulation on walking function in patients with stroke.Methods Fifty patients with post-stroke walking dysfunction who met the inclusion criteria were selected for 3-week rehabilitation treatment,and were randomly divided into iTBS group(n=25)and sham group(n=25).The iTBS group was treated with conventional rehabilitation therapy combined with iTBS stimulation of contral-esional cerebellum,and the sham group was treated with conventional rehabilitation therapy plus iTBS stimulation of contralesional cerebellum.Relevant indicators were analyzed before treatment and at 21 days of treatment.Lower limb motor function scores of the two groups were compared before and after treatment.Fugl-Meyer motor function lower limb activity score,Berg Balance Scale score,Brunnstrom stage(lower limb),hamstring/quadriceps(H/Q)on the affected side,Modified Barthel index(MBI),gait analysis parameters,and TMS-MEP were used to evaluate the effectiveness of cerebellar iTBS in the rehabilitation of walking dysfunction after stroke.Results After 21 days of treatment,the improvements of Brunnstrom stage,Holden grade,Berg score,FMA score,6-minute walking dis-tance,NIHSS score and MBI score in iTBS group were significantly better than those in sham group(P<0.05).Af-ter treatment,the H/Q in iTBS group was significantly higher thanbefore(P<0.05),but there was no significant difference between the two groups(P>0.05).Stride speed,stride frequency,stride width,single support phase on the affected side and GDI score in iTBS group were significantly improved compared with sham group(P<0.05),and there was no significant difference in stride length between the two groups after treatment(P>0.05).The amplitude of MEP in the affected cerebral cortex of iTBS group was lower after treatment than before(P<0.05).Conclusion Contralesional cerebellar iTBS combined with routine rehabilitation could improve lower limb walk-ing function and daily living ability of stroke patients.
