Traumatic brain injury (TBI) is a highly complex multi-factorial disorder. Animal models of TBI are used to elucidate primary and secondary injury mechanisms and pathophysiological changes and to provide the diagnostic and therapeutical basis for TBI. The choices of animal models depend upon the research objectives. ⋯ The characteristics of human TBI can not fully be reflected by using these models. In the review, animal models of traumatic brain injury are classified as dynamic direct brain injury, indirect dynamic brain injury and combined neuro-traumatic models.

In forensic psychiatric evaluation, experts frequently need to assess the contribution degree of hurting factors to the victims. The contribution degree reflects the extent of hurt caused by the injurer and is the quantitative index of the responsibility which should be undertaken by the injurer. ⋯ Presently, there is no accepted and practicable quantitative tool to reflect the objective contribution degree. This article reviews domestic and international researches on the contribution degree of hurting factors in mental injury, including the concept, connotation, related assessment methods, problems in assessment and its future study trend.
