RESUMO
Objective@#To explore the effectiveness of cognitive behavioral therapy on adolescent violent behaviors.@*Methods@#A total of 120 middle school students with violence or violence tendency were selected from Lianbei Middle School in Shijiazhuang and divided into intervention and control group( n =60). The intervention group received comprehensive cognitive behavioral intervention while the control group did not. The changes of violence, violent risk, impulsive behavior and explicit aggressive behavior before and after intervention were compared between the two groups.@*Results@#The scores of personality insult, relational aggression, self abuse, suicide ideation, severe violence dimension and total violence in the intervention group decreased significantly compared to before intervention( t =6.32，7.88，10.05，7.05，9.27，8.01， P <0.05). No similar changes were observed in the control group( t =0.35，0.24，1.01，0.78，0.49，0.53， P >0.05). The scores of personality insult, relational aggression, self abuse, suicide ideation, severe violence and total violence in the intervention group were significantly lower than those in the control group( P <0.05). In the intervention group, the VRS YV score after intervention was significantly lower than that before intervention, and the proportion of individuals with VRS YV score≥27 after intervention decreased significantly compared to before intervention ( P <0.05) and the control group( P <0.05).@*Conclusion@#The comprehensive cognitive behavior intervention shows effectiveness in improving the empathy ability and reduce the level of violent risk.
RESUMO
OBJECTIVE@#To observe the expression of EphA2, and investigate its correlation with the development, progression, invasion, metastasis, angiogenesis and prognosis in nasopharyngeal carcinoma(NPC).@*METHOD@#Immunohistochemical staining was used to determine the expression level of EphA2 protein in 61 cases NPC and 20 cases chronic nasopharyngitis samples. The clinically pathological data and results of follow-up were collected. Microvessel density (MVD) was also measured by immunohistochemical staining method with CD34 in NPC.@*RESULT@#The positive rate of EphA2 protein staining in NPC was 60.66% (37/61), while that in nasopharyngitis samples was 10.0% (2/20). The positive rates of EphA2 protein in NPC were 27.27% (3/11) in stage I, 56.25% (9/16) in stage II, 68.19% (15/22) in stage III, and 83.33% (10/12) in stage IV. The positive expressions of EphA2 in T1 + T2 and T3 + T4 with neck lymph node and distant metastasis were 58.33% (7/12) and 88.89% (16/18) respectively, while those in T1 +T2 and T3 + T4 without metastasis were 31.25% (5/16) and 50.00% (6/12) respectively. The cumulative survival of patients in the EphA2 positive group at 5 years was only 0.324 (12/37), while 0.500 (12/24) in the EphA2 negative group. The positive expression of EphA2 protein was correlated with the clinical stage, the neck lymph node metastasis and distant metastasis, and prognosis of NPC, respectively (P < 0.05). MVD in EphA2 protein positive group (45.32 +/- 4.91) was significantly higher than that in EphA2 protein negative group (28.69 +/- 3.99, P < 0.01).@*CONCLUSION@#EphA2 may play an important role in the development and progression of NPC. It is closely associated with the invasion, metastasis, angiogenesis and prognosis of NPC.
