[Causes and clinical features of children with traumatic brain injury: a retrospective analysis of 126 cases].

Objective: To investigate the causes and clinical features of children with traumatic brain injury (TBI) who need hospitalization or emergency observation.

Methods: A retrospective analysis was performed for the clinical data of 126 children with TBI who were admitted to the emergency department from January 1, 2014 to August 31, 2016, including causes of injury and clinical features.

Results: Of the 126 children, there were 95 boys and 31 girls, with a mean age of 2.

[Porphyrins with different electron groups: spectral and DFT study].

UV-Vis absorption spectra and electrochemical properties of 5-(o-hydroxyphenyl)-10, 15, 20-tri-(p-phenyl)porphyrin (TPPOH) and 5-(o-hydroxyphenyl)-10, 15, 20-tri-(p-methoxyphenyl) porphyrin [(p-OCH3)TPPOH] with different electron groups were investigated by experiments and density functional theory (DFT). Due to the introduction of para-methoxyl group (-OCH3), obvious red shift of 3 nm in the maximum absorbance of the UV-Vis spectra, negative shift in redox potential of (p-OCH3)TPPOH, and the decrease (0.06 eV) in the energy gap (DE) of the frontier highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) (of (p-OCH3)TPPOH occurred as compared to those of TPPOH.

[Correlation between psychopathological symptoms, coping style in adolescent and childhood repeated physical, emotional maltreatment].

Objective: To study possible relationship between psychopathological symptoms, positive and negative coping styles in adolescents who experienced repeated serious childhood physical abuse (CPA), moderate CPA, and childhood emotional abuse (CEA).

Methods: A total of 5453 students were recruited as subjects from 9 middle schools at grades 7, 8, 10, and 11. They provided informed consent and participated in the self-administered anonymous survey on their frequencies of serious or moderate physical abuse and emotional abuse by his/her parents or other caregivers about average times of experiencing maltreatment every year during primary school.
