Objective To investigate the temperament of children with epilepsy and the effects of various epilepsy-related variables on it. Methods The temperament of 60 pairs of epilepsy and normal children were assessed by temperament scale. The results of the two groups were compared. Epilepsy-related variables were analyzed. Result The scores of all dimensional variables in the epilepsy group were higher than that in normal group. The differences in adaptability and intensity of response between the two groups was statistically significant ( P <0. 05), and the differences in rhythmicity, approach-withdrawal toward new situations, emotional nature and persistence were more notable ( P <0.01). The temperament of epilepsy children was incline to difficult temperament( X2 = 10. 91, P <0.01). Age at onset of epilepsy, main caregiver and maternal education level had impaction on the temperament of epilepsy children..Conclusions The temperaments of epilepsy children tend to be negative. Children's temperaments are inclined to easy when their mothers are well educated and their main caregivers are parents, while they tend to be difficult temperament when the age of onset is early.

Objective To observed the analgesia and adverse reactions of continuous patients-controlled in-terscalene analgesia with patient-controlled intravenous analgesia for the shoulder arthroscopic surgery.Methods 40 patients with ASA Ⅰ ~Ⅱ anesthesia in general anesthesia for the shoulder arthroscopic surgery were selected and randomly divided into the two groups,20 cases in each group.They were continuous patients-controlled interscalene analgesia(PCNA)and patient-controlled intravenous analgesia (PCA).PCNA with 0.2% ropivacaine +saline to 100mL,background parameters 4ml/h,a single dose of 0.5mL,lock 20min.24 hours after dosing.PCA with fentanyl lmg +tropisetron 5mg +saline to 100mL,background parameters 2mL/h,a single dose of 3.5mL,lock 20min.Record the VAS score 6h,12h,24h,48h after surgery,and adverse side effects of postoperative dizziness,nausea,vomiting and itchy skin.And the patient's analgesic satisfaction survey 48h after surgery.Results PCNA after surgery 6h,12h, 24h,48h in VAS score was significantly lower than the PCA(P <0.05).PCNA were dizziness,nausea,vomiting and the incidence is lower than the PCA,the difference was statistically significant(P <0.05).The PCNA of patients sat-isfaction was 100%,the PCA of patients satisfaction is 75%,the difference was statistically significant(P <0.05). Conclusion In the postoperative analgesia of shoulder arthroscopic surgery,the analgesic effect and patient satisfac-tion of continuous patients-controlled interscalene analgesia are better than patient-controlled intravenous analgesia. And the dizziness,nausea,vomiting is lower.

Objective: To explore the mediating effects of adolescent loneliness and depressive symptoms on interparental conflict and adolescent non-suicidal self-injury, so as to provide insights into the prevention and interventions of adolescent non-suicidal self-injury. Methods: Students from 7 middle schools in Tianjin, Henan, Sichuan, Zhejiang and Inner Mongolia were selected using convenient sampling method. Their loneliness, depressive symptoms and non-suicidal self-injury occurrence were investigated using the Three-Item Loneliness Scale, the Center for Epidemiological Studies Depression Scale and Non-Suicidal Self-injury Scale, and interparental conflict was evaluated by adolescents and their mothers respectively, using the adolescence revision of Co-parenting Scale and the Co-parenting Relationship Scale. The mediating effects of loneliness and depressive symptoms on interparental conflict and non-suicidal self-injury was examined using a structural-equation model. Results: A total of 544 students were recruited, with a mean age of (14.19±; 1.43) years. There were 241 males (44.30%) and 303 females (55.70%); 452 junior high school students (83.10%), 46 high school students (8.45%) and 46 vocational high school students (8.45%); and 150 students with non-suicidal self-injury (27.57%). The scores of loneliness, depressive symptoms, parental conflict evaluated by students and their mothers were (4.38±; 1.87), (7.32±; 6.06), (14.10±; 8.03) and (3.04±; 3.19), respectively. The results of structural equation model analysis showed that parental conflict had no direct effect on non-suicidal self-injury, but loneliness (β=0.074, 95%CI: 0.038-0.114) and depressive symptoms (β=0.096, 95%CI: 0.061-0.136) played indirect effects on interparental conflict and non-suicidal self-injury, and they also exerted a chain mediating effect (β=0.064, 95%CI: 0.037-0.095) (all P<; 0.05). Conclusion Interparental conflict can impact adolescent non-suicidal self-injury through the mediating effects of adolescent loneliness and depressive symptoms.

Objective To evaluate the diagnostic value of galactomannan(GM) detection for invasive aspergillosis infections in pediatric patients, a Meta-analysis was performed.Methods According to selection criteria, studies indexed by PubMed,EMBASE,Medline,CNKI and Wanfang Data on GM testing in pediatric aspergillosis were included from January 2001 to November 2012. The methodological quality was assessed by QUADAS, sources of heterogeneity investigated, pooled effect quantities evaluated, and summary receiver operative curves(ROC) and subgroup analysis performed.Stata12.0 was used to analyze diagnostic parameters, such as, sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and area under the curve(AUC).

Objective To investigate the effects of human papilloma virus 16 E6 (HPV16 E6) on endoplasmic reticulum (ER) stress-autophagic response in the cervical cancer C33A cells.Methods Polymerase chain reaction was used for detecting the integration of HPV DNA.The eukaryotic expression vector of HPV16 E6 was constructed and transfected via lipofectamine into C33A cells.Experimental cells were classified into 3 groups:pcDNA3.1--HPV16 E6 group,pcDNA 3.1-group and C33A group.Western blot was used to measure expression of protein of HPV16 E6,Beclin 1,LC3 Ⅱ,IRE1,PERK and ATF6 in transfected cells.Results here was no HPV DNA integration in C33A cells that were confirmed as the intervention cells.Eukaryotic expression vector pcDNA3.1--HPV16 E6 was constructed successfully.The eukaryotic expression vector pcDNA3.1--HPV16 E6 significantly improved the expression of protein of HPV 16 E6 in C33A cells.The protein expression of Beclin 1,LC3 Ⅱ,IRE1,PERK and ATF6 were significantly improved after transfection with vector pcDNA3.1 +-HPV16 E6 (P ＜ 0.05).Furthermore,LC3 Ⅱ protein level was reduced by treatment with ER stress inhibitor.Conclusion HPV16 E6 can improve autophagy through the ER stress pathway,and this response may play an important role in the process of HPV16 E6 inducing cervical cancer,providing one of the new strategies for gene therapy of cervical carcinoma.

Objective To observe the changes of behavior, intracellular free calcium and the expression of calmodulin dependent protein kinase Ⅱ(CaMKⅡ) in the hippocampal neurons of chronic forced swimming stress rats. Methods Male Wistar rats were randomly divided into control group and chronic forced swimming stress group. The behavior was examined using sucrose preference test, open-filed test and Morris water maze. The intracellular free calcium was examined by fluorescence spectrophotometer. The expression of CaMKⅡ was detected using colloidal gold immunoelectron microscopy technique, Western blotting and RT-PCR. Results The consumption of sucrose and erect quantity of chronic forced swimming stress group were lower than those of control group(P<0.01, P<0.05). The escape latency time in Morries water maze test of chronic forced swimming stress group was higher than that of control group(P<0.01). The intracellular free calcium level and the expression of CaMKⅡ in the hippocampus was higher than that of control group(P<0.01).Conclusion The lasting dysfunction of Ca~(2+)/CaMKⅡ signaling cascades in hippocampus may play important roles in the pathogenesis of chronic forced swimming stress rats.
