Objective To study the relationship between self-esteem and childhood abuse, life events among male violent adolescent. Methods According to the modified overt aggression scale, juvenile delinquents were divided into violent group (n = 128 )and nonviolent group (n = 118 ). All the participants were investigated by Self-Esteem Scale (SES), Childhood Trauma Questionnaire-28 Item Short Form (CTQ-SF) and Adolescent SelfRating Life Events (ASLEC) and conducted correlation and regression analysis. Results ①Violent group had lower self-esteem scores ( 22.73 ± 3.30 ) than the nonviolent group ( 23.81 ± 3.30, P ＜ 0.05 ). Violent group had higher scores in physical abuse, sexual abuse, total life events, interpersonal relationship, punishment, and other (8.30 ±4.07, 7.23 ±2.26, 54.48 ±18.60, 10.09 ±3.84, 14.43 ±5.87, 4.93 ±3.15, 9.93 ±3.64), compared to the nonviolent group (7.27 ± 3.27, 6.60 ± 2.09, 45.40 ± 18.45, 8.42 ± 4.13, 11.07 ± 5.75, 3.66 ±2.81, 7.84 ±3.66, P＜0. 05). ②The self-esteem was significantly negative correlated with the childhood abuse and life events( r= -0. 143 ～ -0. 358, P＜ 0.01 ) among violent male adolescents. ③The physical abuse and punishment had significant prediction function of 15.6% on self-esteem. Conclusions Violent adolescents have low self-esteem, which is closely related to childhood abuse and adolescent life events.

The demographic and clinical data were colected. Immunoturbidimetric assay was used to detect serum CysC level. Results A total of 94 consecutive patients w ith HICH and 131 healthy controls w ere enroled. The baseline systolic blood pressure ( 168.57 ±28.64 mmHg vs.128.13 ±16.23 mmHg; t=-13.442, P<0.001;1 mmHg=0.133 kPa), diastolic blood pressure ( 95.56 ±14.68 mmHg vs.76.80 ± 8.76 mmHg; t= -11.965, P<0.001 ), fasting plasma glucose ( 6.24 ±1.83 mmol/L vs.5.22 ± 1.13 mmol/L; t= -4.234, P<0.001), and serum CysC level (1.02 ±0.26 mg/L vs.0.91 ±0.13 mg/L, P<0.001) in the HICH group w ere significantly higher than those in the control group. Multivariable logistic regression analysis show ed that baseline systolic blood pressure≥140 mmHg ( odds ratio [ OR] 12.523, 95% confidence interval [CI] 5.353-29.299; P<0.01), diastolic blood pressure ≥90 mmHg (OR 3.968, 95%CI 1.792-8.784; P<0.01 ) and serum CysC level≥1.09 mg/L ( OR 3.279, 95%CI 1.336-8.050; P<0.05) w ere the independent risk factors for HICH. In patients w ith HICH, the CysC serum level (1.13 ±0.26 mg/L) in the bleeding ≥30 ml group w as higher than that in the bleeding <30 ml group (0.99 ±0.25 mg/L; P<0.001) and the control group ( 0.91 ±0.13 mg/L; P<0.001). The serum CysC level in the bleeding volume <30 ml w as higher than that in the control group ( P=0.004). There w ere positive correlations betw een serum CysC and age, creatinine, urea, and uric acid (al P<0.01);there w ere negative correlations betw een serum CysC level and the estimated glomerular filtration rate ( P<0.01). Multivariable linear regression analysis show ed that age, creatinine, urea and uric acid w ere independent associated w ith the serum CysC level ( al P<0.05 ). Conclusions The increased serum CysC level is correlated w ith the amount of bleeding in patients w ith HICH. The increased serum CysC level is an independent risk factor for HICH.

Objective: To study the relationship between serum levels of insulin-like growth factor-1 (IGF-1), cystation-C (Cys-C), interleukin-6 (IL-6) and atherosclerosis in middle and old age patient with newly diagnosed type 2 diabetes mellitus (T2DM). Methods: A total of 206 patients with newly diagnosed T2DM at the age of (67.3±10.4) years were enrolled. Based on color Doppler ultrasound examination, the patients were divided into 2 groups: Control group, the patient without carotid plaque or increased intima thickening, n=105 and Experiment group, patient with carotid plaque or increased intima thickening, n=101. The general information, fasting blood glucose, 2h postprandial blood glucose, glycosylated hemoglobin, LDL-C, HDL-C, TG, TC and IGF-1, Cys-C, IL-6, hs-CRP were recorded and compared between 2 groups, BMI was calculated in all patients. Results: Compared with Control group, Experiment group had increased carotid intima-media thickness (CIMT), elevated serum levels of Cys-C, IL-6, hs-CRP and reduced IGF-1, allP<0.05. Multiple Logistic regression analysis showed that CIMT was negatively related to IGF-1 (r=-0.493,P<0.01), positively related to Cys-C, IL-6 and hs-CRP (r=0.464,r=0.219 andr=0.618, allP<0.01). Conclusion: Serum levels of Cys-C and IL-6 might be the independent risk factors for atherosclerosis occurrence in meddle and old patients with T2DM; combined detection of IGF-1, Cys-C and IL-6 could help clinical diagnosis in relevant patients.

Objective To compare the cognitive function of patients with carotid stenosis combined with white matter lesions (WML)after carotid artery stenting (CAS). Methods Total 166 patients with carotid artery stenosis were collected.According to MRI imaging,30 patients with no white matter lesions were included in the control group and 136 patients with white matter lesions were included in the white matter lesions group. They were treated with carotid artery stenting and underwent evaluation on the safety and efficacy of perioperative surgery. CAS failed in two patients because of the inability of guidewire crossing in WML group. Two patients died after CAS (one for cardiac death and one for traumatic accident) in WML group. 162 patients received 1 year follow-up. Cognitive function was assessed before and after CAS. Results Before CAS,WML group's MMSE, digit span forward/backward test, verbal fluency test and MoCA scores (21.8±3.3、6.3±2.1、4.1±1.0、15.1±3.6、20.6±3.1) were lower compared with control (24.3±3.9、7.3±2.6、4.7±1.8、17.7±5.2、22.7±4.2) and ADAS-Cog score was higher compared with control ((15.1±3.3) vs.(12.7±3.3)), P=0.000、0.026、0.039、0.012、0.000、0.011.Three months after CAS,the MMSE,digit span forward test and MoCA scores (23.7±3.6,7.5± 2.4, 23.1±6.9) was higher significantly than those before treatment (21.8±4.3, 6.3±2.09, 20.6±4.13), P<0.05.And the scores of ADAS-Cog was lower((13.2±4.)vs.(15.1±4.3),P<0.05).The scores of digit span backward test in 6 months after treatment was significant higher than those before treatment (4.9 ±2.8,4.1 ±2.2,P<0.05). After 1 year of CAS, the improvement in scores of MMSE, digit span forward test, ADAS-Cog and MoCA in patients with carotid stenosis complicated with WML(3.5±1.3,1.6±0.6,-2.6±0.8,3.6±1.1)was higher significant than control(2.7±1.8, 1.2±0.8, -2.0± 1.3, 2.7 ±1.5),P<0.05. Conclusion CAS can improve cognitive function in Patients with carotid artery stenosis complicated with WML than those who without WML.

Objective:To evaluate the effect of propofol on proliferation, invasion and migration of human melanoma cells and role of cyclooxygenase-2 (COX-2)/prostaglandin E2 (PGE2)/matrix metalloproteinase (MMP) signaling pathway.Methods:SKMEL-5 cells were cultured in vitro and divided into 4 groups ( n=36 each) using the random number table method: control group (group C), propofol group (group P), COX-2 overexpression group (group COX-2), and COX-2 overexpression plus propofol group (group COX-2+ P). Propofol at the final concentration of 60 μmol/L was added in group P. The COX-2 overexpression plasmid pcDNA3.1-COX-2 was transfected into SKMEL-5 cells in group COX-2 and group COX-2+ P, and propofol at the final concentration of 60 μmol/L was added in group COX-2+ P.After incubation for 48 h, the cell proliferation rate was determined by CCK-8 method, the cell invasion and migration ability was determined by Transwell assay, the expression of COX-2 in cells was detected by Western blot, the expression of COX-2 mRNA in cells was detected by quantitative real-time polymerase chain reaction, and the concentrations of serum PGE2, MMP-2 and MMP-9 were determined by enzyme-linked immunosorbent assay. Results:Compared with group C, the cell proliferation rate was significantly decreased, the number of cell invasion and migration was decreased, the expression of COX-2 protein and mRNA was down-regulated, and the concentrations of PGE2, MMP-2 and MMP-9 in the supernatant were decreased in group P, and the cell proliferation rate was significantly increased, and the number of cell invasion and migration was increased, the expression of COX-2 protein and mRNA was up-regulated, and the concentrations of PGE2, MMP-2 and MMP-9 in the supernatant were increased in group COX-2 ( P<0.05). Compared with group P, the cell proliferation rate was significantly increased, and the number of cell invasion and migration was increased, the expression of COX-2 protein and mRNA was up-regulated, and the concentrations of PGE2, MMP-2 and MMP-9 in the supernatant were increased in group COX-2+ P ( P<0.05). Conclusions:Propofol can inhibit the proliferation, invasion and migration of human melanoma cells, and the mechanism may be related to inhibition of the COX-2/PGE2/MMP signaling pathway.
