Objective To explore the factors in frequency and degree of risk behavior in adolescents,as well find the way to cope with adolescent mental health. Methods 1369 middle students and college students were measured by Risky Behavior Questionnaire for Adolescents (RBQ-A) ,and analyzed the data. Results (1) There were statistically significant among the different age in difference of risky behaviors except aggressive and/or violent behaviors. Males scored higher than females in unsafe sexual practices, aggressive and/or violent behaviors, dangerous,destructive,and/or illegal behaviors,alcohol and/or drug use and smoking(P<0.05 orP<0.01). Students in city scored higher than rural students in dangerous,destructive,and/or illegal behaviors and alcohol and/or drug use(P<0.05 or P< 0.01). Families with high income scored higher than low income in unsafe sexual practices and rule breaking(P< 0.05 or P< 0.01). Families with low income scored higher than high income residences in dangerous,destructive,and/or illegal behaviors and alcohol and/or drug use(P < 0.05 or P < 0.01). (2) The significant differences were existed in unsafe sexual practices,aggressive and/or violent behaviors,dangerous, destructive,and/or illegal behaviors,alcohol and/or drug use and smoking between males and females (P<0.05 or P<0.01).The significant differences were existed in dangerous,destructive,and/or illegal behaviors and alcohol and/or drug use between groups of 16 years old and 14 ～ 15 years old (P < 0. 05 or P < 0. 01). The significant differences were existed in dangerous,destructive,and/or illegal behaviors between urban and rural students (P< 0.05 orP<0.01).The significant differences were existed in total scores in gender and urban and rural(P<0.05 or P<0.01). Conclusion The significant differences are existed in rate of risky behaviors in gender,age,urban and rural. But there is different degree existed in it.

Objective To explore the autobiographical memory characteristics of chronic pain patients and its correlators.Methods Autobiographical memory,pain and emotion of 106 chronic pain patients and 106healthy controls were assessed with the Autobiographical Memory Test (AMT), the Short-form McGill Pain Questionnaire (SF-MPQ), the Pain Self-efficacy Questionaire (PSEQ), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI).Results Compared to the control group, the clinical group had less specific memory (3.63 ± 1.53, 2.63 ± 1.68, F (1.416) = 7.233, P ＜ 0.01 ) and more overgeneral memory (2.37 ± 1.53,3.37 ±1.68, F (1.416) =7.069, P＜0.01 ),but the latency to response was not statistically significantly different between the groups.Duration of pain,frequence of pain and pain self-efficacy were the significant predictors of overgeneral memory,and the regression coefficients were significant (P＜0.05 ) ,the multiple regression equation was statistically significant( R = 0.427, R2 = 0.183, F= 2.385, P＜ 0.05 ).Conclusion The autobiographical memory of chronic pain patients was overgeneralized because of the influence of duration, frequence and self-efficacy of pain.

Objective To explore the biomechanical mechanism of non-erosive reflux disease(NERD).MethodsFrom October 4,2014 to September 30,2015,17 NERD patients and 17 healthy controls were recruited from the outpatients department of China-Japan Friendship Hospital.The cross-sectional area(CSA), intra-balloon pressure (IBP)and compliance(Δv/Δp)of each were measured by endoscopy in combination with EndoFlip.ResultsWith the increase of balloon volume,the compliance of gastroesophageal junction in NERD group was significantly higher than that of control group(P<0.01) while the cross sectional area and intra-balloon pressure were similar.Conclusions Increased compliance of the gastroesophageal junction may be involved in the pathogenesis of non-erosive reflux disease.

OBJECTIVE: To explore the autobiographical memory characteristics in depressed patients and their influence factors. METHODS: Autobiographical memory, emotion and cognitive executive function of 60 depressed patients and 60 healthy controls were assessed with autobiographical memory test (AMT), Hamilton depression scale (HAMD), Beck depression inventory (BDI), Beck anxiety inventory (BAI), hospital anxiety and depression scale (HAD), arrow-task stroop test (ATST), Wisconsin card sorting test (WCST), Backward masking test (BMT) and continuous performance test (CPT). RESULTS: The specific memory of the depressed group was significantly less than that of the control group, and was negatively related with the negative emotion score, the time of anterograde and retrograde reading of ATST, and the time difference of ATST. The overgeneral memory increased and the latency to response of ATST was significantly longer than that of the control group. The two factors were positively related with the negative emotion score, the time of anterograde and retrograde reading of ATST, and the time difference of ATST. CONCLUSION The autobiographical memory of the depressed patients is overgeneralized and retarded. These characteristics are related with negative emotion and impairment of cognitive executive function.

Objective To study topological structure of a new type of three-dimensional (3D) printed height increasing insoles for leg length discrepancy (LLD) and its effect on biomechanics of lower limbs. Methods Topological structure for middle and rear part of the insole was optimized by solid isotropic microstructures with penalization (SIMP), the force was loaded and the boundary conditions were set according to force area of the insole, and the height increasing insole with thermoplastic polyurethanes (TPU) materials was printed by selected laser sintering (SLS). The insoles were used in 9 patients with LLD, visual analogue scale (VAS) and Maryland foot function scores were used to compare pain and foot function changes of patients before and after using the insole, and the 3D gait analysis system was used to compare spatiotemporal parameters and vertical ground reaction force (vGRF) of both lower limbs. Result sAfter the patient wore 3D printed insole, VAS scores decreased, Maryland foot function scores increased, vGRF of both lower limbs decreased, and the difference of cadence, stance phase and swing phase in both lower limbs decreased. Conclusions The 3D printed height increasing insole after topology optimization can improve coordination of lower limb movement, reduce ground impact, relieve pain and improve foot function, thus providing an effective personalized orthopedic plan for LLD treatment in clinic.
