Objective:to study the relationship between YSR and CBCL in adolescents.Method:466 adolescents were collected from 3 middle or high schools by striated random sampling. YSR (youth self report) and CBCL (child behavior checklist) were applied to the adolescents,and their parents .Result:there were 103 questions same in both YSR and CBCL, the Kappa=0.001-0.218 (P=0.975～0.000). In male, the result of YSR was correlated with only one syndrome in CBCL, in female, it correlated with 7 syndromes, introversion/extroversion, and the total score of CBCL. In middle school students, the result of YSR correlated with all subscores of CBCL. In adolescents of core family, in good relationship with parents, with father had higher educational level (high school), the result of YSR correlated with most of the subscores of CBCL.Conclusion:in the population of male, high school students, of non-core family, or in poor relationship with parents, results of YSR and CBCL are not consistent.

Objective: To investigate the related factors to depression in middle and high school students Method: The BDI (Beck depression inventory), EMBU (Egna Minnen av Barndoms Uppufostran, own memories of parental rearing practices in childhood) and a self-designed psychosocial factor inventory were administrated to 1382 students in middle or high schools Result:The BDI score was positively correlated to some factors in EMBU, they were firm control and punishment, over-interference, rejection and deny, and over-protection Compared with those with low BDI score, the group with higher BDI score had more experiences of fosterage, being maltreated by family members, reared in inharmonious family, unhappy childhood and with more family history of suicide or violent behavior More of them were still in abnormal families, with poor parent-child relationship Their parents had less expectancy on them, they had poor academic achievement, even failed in go up to next grade; they were more bullied and inclined to bully peers, had no good friend, taking less sports or other entertainment, had less opportunity to be assumed class or school service jobs More of them were just before graduation Conclusion:Poor family background, poor school performance and academic stress are risk factors for depression of middle or high school students

Objective:To study the associated factors with suicide ideas in middle school students.Method:Multiple random sample method was used in the study. 1421 middle school students in Chengdu urban area were sampled and 1393 gave effective feedback. Self-made questionnaire (including age, sex, family circumstance, experience in childhood, substance abuse, question about suicide ideas, etc.), Beck Depression Inventory (BDI), Adolescent Self-Rating Life Events Check List (ASLEC) were applied to the students.Results:328 (23.5%) of the 1393 have suicide ideas. The risk factors of suicide ideas included: 1) family factors: parents' divorce, father/mother's passing away, remarried family, experienced abuse in childhood, violence or suicide behavior of family member. 2) school factors: bullying or being bullied. 3) substance abuse: smoking, drinking and addictive drugs abuse. 4) high score of BDI. 5) high score in inter-person relation factor and being punished factor of ASLEC. 6) sex factor: female. Protecting Factors of suicide ideas included better achievement in school, singleton in family and harmony of family member.Conclusion:Suicide ideas were not rare in middle school students. Clinicians and teachers should discover and try to prevent possible suicide as early as possible.

Objective: To develop the Chinese version of the Anxiety Sensitivity Index-Revised and examine its replicability, reliability and validity. Methods: This study translated the Anxiety Sensitivity Index-Revised ( ASI-R) and examined the factor analytic structure of anxiety sensitivity in a large sample of middle school students aged 12-18 years (n = 1556) . Factor analysis of the ASI-R items resulted in a hierarchical construct with three lower-order factors loading on a single higher-order factor. Results: after revision, the number of items of the inventory reduced from 36 to 15. Anxiety sensitivity seems to be a hierarchically organized construct with one higher-order factor (anxiety sensitivity ) and three lower-order factors: Physical concern, Cognitive concern (lose of control) , Social concern, which three factors contributed to 52. 29% of total variance. Factor loadings of items were 0. 63 ~ 0. 98 , the internal correlation between items were 0. 37 ~ 0. 53 , the correlation between factors to the total score were 0. 72 ~ 0. 84, internal correlation among factors were 0. 68 ~ 0. 78. internal consistency of each factor 0. 73 ~ 0. 78. the split-half reliability was 0. 71 ~0. 76, that of test-retest was 0. 70 ~0. 78. Conclusion: The questionnaire has satisfying reliability and validity.

Objective: To explore the personality traits in the people at high risk for schizophrenia.Methods: 188 individuals at high risk for schizophrenia,and 321 normal controls were assessed by Schizotypal Personality Questionnaire(SPQ).Results: The score of negative schizotypal dimension in SPQ in the individuals at high risk was higher than in the normal controls.Conclusion: The people at high risk for schizophrenia have negative schizotypal personality traits which may represent a genetic endophenotype for schizophrnia.

ObjectiveTo investigate the association between catechol-O-methyl transferase (COMT)gene polymorphism and Gilles de la Tourette' s syndrome(GTS).MethodsUsing Amplification Refractory Mutation System(ARMS) PCR genotyping assay method,a polymorphism (val158met) of COMT gene was genotyped in 112 of all GTS patients ( total GTS group) including 54 GTS-alone patients group,48 GTS + ADHD patients group among of them and 71 healthy controls.The correlation between positive association of polymorphism (val158met)of COMT gene in GTS and the age of onset in patients with GTS was also analyzed.ResultsCompared with healthy controls group,genotype of val158met did not differ in total GTS patients group or alone-GTS patients group (χ2 =0.56,P=0.756;χ2 =1.05,P=0.600 respectively).There was also no significant difference (P＞0.05)in allele distribution of val158met in total GTS patients group or alone-GTS patients group compared with controls group respectively (χ2 =0.18,P=0.669;χ2 =0.29,P=0.593 respectively).However,genotype distribution of val158met was significantly different between GTS + ADHD patients group and controls group( χ2 =6.35,P =0.041 ).The frequency of the val allele of this locus was significantly higher in GTS + ADHD patients group than those in controls group ( χ2 =5.49,P =0.019 ).The mean age of onset (6.80 ± 1.54 ) in 36 children within GTS + ADHD patients group with the val/val geantype of COMT gene val158met polymorphism was significantly earlier than the mean age of onset (8.04 ± 1.54)in 12 children in val/val genotype (P =0.016 ).ConclusionPolymorphism (val158met) of COMT gene may be associated with GTS children with comorbid ADHD,which may play an important role to make the age of onset in children with GTS become earlier.

Objective To assess the changes of left ventricule and analyze the influential factors in pulmonary hypertension (PH) by comparing the changes of left ventricular volume and function using single cardiac cycle real-time three dimensional echocardiography ( sRT-3DE ) and two-dimensional echocardiography (2DE).Methods In case group,there were 30 inpatients diagnosed as PH,systolic pulmonary artery pressure(PASP)≥40 mmHg estimated by echocardiography,excluding left heart disease or congenital systemic-pulmonary circulation shunt.There were 30 healthy people as control group.Conventional 2DE and sRT-3DE were performed in both groups and obtained 2D and 3D parameters.Results ①In case group,the 2D-LVEF were significantly larger than 3D-LVEF (P ＜ 0.01 ).There was less agreement of 2DE and 3DE in case group than in control.②Comparing with the control group,left ventricular EDV,ESV and SV in ease group decreased ( P ＜0.01 ),so as to 3D-LVEF ( P ＜0.05).The left ventricular spherical index(SIs,SId)and eccentric index (EId,EIs ) in case group were significantly larger than those in control group ( P ＜0.01 ).③LVEDV in case group was negatively correlated with PASP (r =- 0.47),and positively correlated with RVSV and RVEF ( r =0.84,0.66) ;3D-LVEF in case group was negatively correlated with PASP ( r =- 0.54),and positively correlated with RVSV and RVEF ( r =0.58,0.53); there was no significant correlation between LVEDV and RVEDV.LVEDV was negatively correlated with SIs and SId ( r =-0.65,-0.61),so as to EId and EIs ( r =-0.67,0.67).LVEF was negatively correlated with SIs and SId ( r =-0.64,-0.61),so as to EId and EIs ( r =-0.66,-0.68),and the corresponding P all above were less than 0.01.Conclusions PH can result in reductions of left ventricular volume and systolic function,and the variations of which have the correlations with the severity of PH and the increase in SI and EI.sRT-3DE can provide a method to get more accurate information of left ventricle.

Objective To assess the safety and efficacy of abdominal radical nephrectomy and systematic lymph node dissection for treatment of renal carcinoma. Methods A total of 136 patients underwent radical nephrectomy and regional clearance of lymph nodes from July 2004 to June 2008.There were 92 males and 44 females in the study group.Ages ranged from 23 to 81 years,with a mean age of 54 years.The mean tumor diameter was 55 mm (range,15-170 mm).The tumor size detected by CT and MRI was consistent with that detected by B-ultrasound,98 were stage Ⅰ,13stage Ⅱ,12 stage Ⅲ,and 2 stage Ⅳ. Results All 136 cases underwent radical nephrectomy with retroperitoneal lymphadenectomy.All operations were successful without any major complication.The operative time was 90 to 180 min,with an average of 120 min,and blood loss was 20-400 ml,with an average of 50 ml.The pathological diagnoses were as follows: renal cell carcinoma 123 cases (90%), papillary renal cell carcinoma six cases(4%),chromophobic two cases(1.4%),oncocytoma two cases(1.4%),collecting duct two(1.4%),and others three cases(2.2%).Eight cases reported positive lymph nodes.Of the 136 cases,92 cases were T1 N0 M0,11 were T2 N0 M0,10 were T3 N0 M0,eight were T3 N1 M0 and two were T1 N0 M1.Ninety-five cases (70%) were followed-up at six to 40 months (mean,20 months).The one year and three year survival rates were 96% (91/95) and 86% (82/95),respectively.Conclusions Radical nephrectomy with systematic lymph dissection has advantages of accurate staging,effective resecting of renal tumors and preventing recurrence.Radical nephrectomy is an effective method for the treatment of renal carcinoma.

Objective To evaluate the therapeutic efficacy and treatment-related toxicity of stereotactic body radiation therapy(SBRT)in patients with medically inoperable stage Ⅰ/Ⅱ non-small cell lung cancer(NSCLC). Methods SBRT was applied to 30 patients, including clinically staged T1 ,T2(≤5cm)or T3(chest wall primary tumors only), N0, M0 ,biopsy-confirmed NSCLC. All patients were precluded from lobotomy because of physical condition or comorbidity. No patients developed tumors of any T-stage in the proximal zone. SBRT was performed with the total dose of 50 Gy to 70 Gy in 10 - 11 fractions during 12 - 15 days. prescription line was set onthe edge of the PTV. Results The follow-up rate was 100%. The number of patients who completed the 1-, and 2-year follow-up were 15, and 10, respectively. All 30 patients completed therapy as planned. The complete response(CR), partial response(PR)and stable disease(SD)rates were 37%, 53% and 3%, respectively. With a median follow-up of 16 months(range,4-36 months), Kaplan-Meier local control at 2 years was 94%. The 2-year overall survival was 84% and the 2-year cancer specific survival was 90%. Seven patients(23%)developed Grade 2 pneumonitis, no grade ＞ 2 acute or late lung toxicity was observed. No one developed chest wall pain. Conclusions It is feasible to deliver 50 Gy to 70 Gy of SBRT in 10 - 11 fractions for medically inoperable patients with stage Ⅰ / Ⅱ NSCLC. It was associated with low incidence of toxicities and provided sustained local tumor control.The preliminary investigation indicated the cancer specific survival probability of SBRT was high. It is necessary to perform similar investigation in a larger number of patients with long-term follow-up.
