Methods: A total of 500 college students were surveyed by CES-D and SAS, and 77 college students were chosen for further experiment: 24 with depressive mood, 12 with anxious mood, 17 with both depressive and anxious mood, and 24 normal ones. Sociotropic adjectives were strictly developed, and the 4 groups (depressive vs. anxious vs. depressive and anxious vs. normal) were given Self-referent Encoding Task. Results: ①The depressive group showed significantly less positive adjectives and more negative adjectives for self-descriptive than the normal group (P

Objective To test whether adolescent rats are more sensitive than adult rats to morphine' s rewarding actions and locomotor activating effects. Methods Conditioned place preference(CPP) procedure was used to examine drug-induced reward and locomotor activity. Adolescent ( Postnatal day 35 ) and adult ( P67 ) male rats received either saline or morphine (3 mg/kg) for 6 days and the locomotor response in the drug paired chamber was recorded during conditioned training. CPP effects were tested 24h after the last training. Results In adolescent rats, morphine CPP effect was not present [ saline group (20. 89 ±31. 14) s, morphine group (90. 75 ± 27.91)s, P = 0. 15], however, morphine CPP effect occurred in adult rats[saline group (31.5 ± 41. 24) s, morphine group(266. 13 ± 32. 26) s, P < 0. 001 ]. Adult rats presented higher CPP score than adolescent rats(P < 0.001). The locomotor response was significantly higher in day 3 ～ 6 than day 1 in the adolescent treated with morphine (P<0.05 or <0. 01). The locomotor response was significantly higher in day 2-6 than day 1 in the adolescent treated with morphine(P<0. 05 or < 0. 01 ) .which suggested that both adolescent and adult rats exhibited similar behavioral sensitization to morphine administration. Two-way ANOVA indicated that the main effect of age was not significant(F_(1,14) =0. 33, P = 0. 57) ,the interaction effect of age x treat was not significant(F_(5,70) = 0.85, P = 0.52) .there was no age difference between adolescent and adult rats in behavioral sensitization effects. Conclusion Compared with adult rats, adolescent rats don' t present morphine CPP, but show the similar morphine behavioral sensitization.

Objective To explore the mediating effects of college students＇ online social support on the relationship between online self-disclosure and internet altruistic behavior.Methods Using cluster random sampling,the self-disclosure questionnaire for Chinese undergraduates with their internet friend,the online social support scale of adolescence and the internet altruistic behavior scale of undergraduates were applied to 351 college students.Results The score of college students＇ online self-disclosure,online social support and internet altruistic behavior were respectively(2.22±0.45),(2.93±0.59) and (2.04±0.46).The college students＇ online self-disclosure,online social support and internet altruistic behavior were positively correlated with each other (P＜0.01).College students＇ online self-disclosure not only predicted internet altruistic behavior directly,but also predicted internet altruistic behavior indirectly through online social support.The direct effects and indirect effects were 0.200 and 0.265.The ratio of the mediating effect on the total effect was 57％.The fit index of mediation model was x2/df=2.87,RMSEA =0.07,CFI =0.94,TLI =0.93,GFI=0.92,IFI=0.94,NFI=0.91.Conclusion The college students＇ online self-disclosure not only affects the interuet altruistic behavior directly,but also can take the same effect on online social support indirectly.

OBJECTIVE: Assessed the feasibility of application of free fibular flap and clinical significance of pre-operational contrast enhanced CT angiography in functional reconstruction of oral and maxillofacial hard and soft tissue defects. METHOD: Eight cases with mandibular and soft tissue defects received a free fibula flap using arteriovenous anastomosis anastomosis method. The relationship between fibula flap design, size, repair parts and survival were analyzed. Preoperative enhanced CT angiography (CTA) examination was conducted to detect any abnormal blood vessels in fibula flap valve area. RESULT: Peroneal artery and posterior tibial artery variation was identified in one case of gums cancer, who used other muscle flap. Free fibula flap in the other 7 cases survived, which carried a skin island with an area ranging from 6 cm x 2 cm to 10.0 cm x 3.5 cm. Postoperative facial appearance, functionality, dental occlusion and voice function was normal. Lower limb function returned to normal from 2 weeks to 4 months after surgery. CONCLUSION CTA examination of the free vascularized fibula flap in the preoperative evaluation of the donor site is a valuable tool. Free fibula flap of bone, periosteum and bone marrow has a dual blood supply and are highly resistant to infection after transplantation. Personalized shaping osteotomy allowed for accurate recovery of mandibular alveolar patterns. Furthermore, the height and width of the fibula and the thickness of cortical bone is suitable for dental implants. Free fibula flap skin island can also be used to monitor the post-operative blood supply and is an ideal technique for mandible and soft tissue defects reconstruction as well as functional restoration.

BACKGROUND:Caspase plays a crucial role in the cellapoptosis, but the influence of different facial nerve injury on caspase 1, caspase 8, cyto-c protein expression and their correlation stil remain unclear.
OBJECTIVE:To construct facial nerve crush or distal transection injury models, observe the morphological changes of facial motoneurons, investigate death gene caspase 3, caspase 8, cyto-c expression, and analyze their correlation.
METHODS:Facial nerve crush or distal transection injury model was established in the right facial nerve of rats, while the left facial nerve served as normal controls. We observed the morphology and the death of facial motoneurons with toluidine blue staining and transmission electron microscope. Expressions of caspase 3, caspase 8 and cyto-c proteins were studied by immunohistochemistry analysis fol owing facial nerve injury.
RESULTS AND CONCLUSION:Both facial nerve distal transection and crush injury resulted in the death of facial motoneurons, and the death pattern was mainly apoptosis. Caspase 3, caspase 8 and cyto-c protein expressions were observed in the subnucleus of normal rat facial nucleus. cells of the distal transection group were stained more intensely than that of crush group. Expressions of these proteins began to increase at 3 days after the injuries. Caspase 3 and caspase 8 protein expression peaked at 14 days, whereas cyto-c protein expression peaked at 7 days after the injuries. Expressions of caspase 3, caspase 8 and cyto-c proteins were correlated with facial nerve injury type and injury time. Expressions of caspase 8 and cyto-c protein were correlated with expression of caspase 3 protein. The findings indicate that, caspase 8 and cyto-c contribute to activate caspase 3, and caspase cascade reaction plays an important role in the apoptosis of facial motoneurons.
