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 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 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 assess the effect of L-carnitine(L-CN)on left ventricular hypertrophy(LVH)in patients undergoing maintenance hemodialysis. Methods Thirty-one patients undergoing hemodialysis were randomly divided into the L-CN group(n =20)and the control group(n = 11). Patients in the L-CN group received additional intravenous injection of 1.0 g L-CN immediately after hemodialysis for a 6-month period. Patients in the control group received isovolumic saline. Using echocardiography,left ventricular mass (LVM),left ventricular mass index(LVMI)and the ejection fraction(EF)were measured before and after the treatment. Plasma calculus,plasma phosphorus and hemoglobin levels were measured. Results The LVM decreased significantly from(252. 03 ±32. 29)g to(204. 47 ± 37.33)g in patients in L-CN group(P < 0. 05),the LVMI decreased significantly from (155.83 ± 23.42)g/m2 to(129. 21 ± 17.46)g/m2 in patients in the L-CN group. However,LVM and LVMI remained unchanged in the control group. Conclusions Supplementation with L-CN induced hypertrophy of LVH in patients on maintenance hemodialysis.
