Forensic Psychiatric Assessment for Organic Personality Disorders after Cranio-cerebral Trauma / 法医学杂志

Objective T o explore the occurrence and the differences of clinical m anifestations of organic personality disorder w ith varying degrees of craniocerebral traum a. Methods A ccording to the Interna-tional C lassification of D iseases-10, 396 subjects w ith craniocerebral traum a caused by traffic accidents w ere diagnosed, and the degrees of craniocerebral traum a w ere graded. T he personality characteristics of all patients w ere evaluated using the sim plified N euroticism E xtraversion O penness Five-Factor Inventory (N E O-FFI). Results T he occurrence rate of organic personality disorder w as 34.6% w hile it w as 34.9%and 49.5% in the patients w ith m oderate and severe craniocerebral traum a, respectively, w hich signifi-cantly higher than that in the patients (18.7% ) of m ild craniocerebral traum a (P<0.05). C om pared w ith the patients w ithout personality disorder, the neuroticism , extraversion and agreeableness scores all show ed significantly differences (P<0.05) in the patients of m ild craniocerebral traum a w ith personality disorder; the neuroticism , extraversion, agreeableness and conscientiousness scores show ed significantly differences (P<0.05) in the patients of m oderate and severe craniocerebral traum a w ith personality disor-der. T he agreeableness and conscientiousness scores in the patients of m oderate and severe craniocerebral traum a w ith personality disorder w ere significantly low er than that of m ild craniocerebral traum a, and the patients of severe craniocerebral traum a had a low er score in extraversion than in the patients of m ild craniocerebral traum a. Conclusion T he severity of craniocerebral traum a is closely related to the in-cidence of organic personality disorder, and it also affects the clinical features of the latter, w hich pro-vides a certain significance and help for forensic psychiatric assessm ent.

Progress of the Recovery Mechanism of Brain Injury Associated with the Gene Polymorphism of Apolipoproteins E / 法医学杂志

Brain injury is a kind of wound by violence on head, which is a mechanical distortion of skull, meninx, cerebral vascular and brain tissue due to outside force acting on head. Apolipoproteins E (ApoE ) is a major kind of apolipoprotein s, participating in the metabolismof lipid and regulating bal-ance of cholesterol. Some recent investigations showthat gene polymorphismof ApoE is associated with various kinds of diseases. Also its immunoreactivity is changed regularly with brain injury. In addition, ApoE has remarkable effect in neurological normal growth and reparative process after brain injury. This article reviews the biological characteristics and mechanismof ApoE in the repair of brain injury and application prospect in forensic medicine, which may be able to provide newideas for estimation of the brain injury time and related experimental research.
