RESUMO

Objective To investigate the mechanism of neural protection of mouse nerve growth factor combined with sub-hypothermia in the treatment of patients with severe traumatic brain injury. Methods 90 cases of severe traumatic brain injury were randomly divided into study group and control group with 45 cases of each group, the control group were given routine treatment; the study group were given on the basis of routine treatment of mouse nerve growth factor combined with sub-hypothermia treatment, with 2 weeks treatment, the clinical indicators and corresponding nerve injury, inflammation, oxidative stress indexes, clinical effect and complications were compared after 2 weeks treatment. Results Compared with before treatment or control group, scores of Glasgow coma scale (GCS) and Glasgow outcome scale (GOS) and montreal cognitive assessment (MoCA) in study group after the treatment increased, National Institute of Health stroke scale (NIHSS) score decreased(P<0.05), neuronspecific enolase (NSE), myelin basic protein (MBP) and S100 beta levels decreased(P<0.05), the serum tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6), IL-10 levels decreased (P<0.05), the malondialdehyde (MDA) decreased, the glutathione peroxidase (GPx) and oxidation resistance (AOA) levels increased (P<0.05). The control group efficiency was 73.33%, the study group efficiency was 91.11%, there was significant difference (P<0.05). All patients were followed up, no case off, there was no significant difference in adverse drug reaction rate between two groups. Conclusion Mouse nerve growth factor and sub-hypothermia has the significant neural protection for patients with severe traumatic brain injury, and its mechanism may be related to reduce nerve injury indicators and improve inflammatory factor and oxidative stress response.

RESUMO

Objective To study the relation between chronic stressful, the neural changes in prefrontal cortex and depression. Methods Adapt chronic unpredictable stress with separate model to make depression model rats. After 22 days all the rats were killed and use immunohistochemistry method and computer image analysis to detect BDNF. To analysis the date with SPSS11.5 software. Results After 21 days stress, body weight ( t =2.915, P < 0.05), ambulation ( t = 6. 245, P < 0. 01 ), rearing( t = 2.693, P < 0. 05 ) and grooming ( t = 2. 685, P<0.05) decreased and stopping time in center( t=2. 388, P<0. 05) ,defecation( t =3. 846, P<0. 01 ) increased in experimental group. BDNF expressed obviously in control group and the prefrontal cortex expressed highly than that of the experimental group. BDNF expressions of experimental group were lower than that in control group ( P< 0.01 ) especially in right prefrontal cortex. Conclusion There was no difference of BDNF distribution in prefrontal cortex between both groups ,but after 21 days stress ,the BDNF levels of experimental rats obviously descent,especially in right prefrontal cortex.
