BACKGROUND:Spinal cord ischemia-reperfusion injury is a serious secondary injury of the spinal cord. Multifactor could contribute to the mechanism of this injury, and many therapeutic measures emerge, but the therapeutic effect is not ideal.
OBJECTIVE:To investigate the protective effects and mechanism of hydrogen-rich saline on spinal cord ischemia-reperfusion injury in rabbits.
METHODS:ZIVIN method was adopted to prepare the model of spinal cord ischemia-reperfusion injury. The rabbit models were randomly divided into model group, sham operation group, and hydrogen-rich saline group.
RESULTS AND CONCLUSION:Improved Tarlov scores for the evaluation of motor function were significantly increased in hydrogen-rich saline group compared with the model group at 6, 12, 24, 72 hours after reperfusion (P<0.01). The contents of malondialdehyde were significantly lower (P<0.05), while catalase activity was significantly higher (P<0.05) in hydrogen-rich saline group than that in model group at 72 hours after reperfusion. Hematoxylin-eosin staining revealed that, spinal cord anterior-horn motor neurons maintained intact structure in sham operation group;more necrotic spinal cord anterior-horn motor neurons were found in model group, and granular-vacuolar degeneration occurred in the endochylema. In hydrogen-rich saline group, the structure of spinal cord anterior-horn motor neurons was basical y intact, only a smal amount of spinal cord anterior-horn motor neurons appeared vacuolar degeneration. TUNEL staining showed no apoptotic spinal cord anterior-horn motor neurons in sham operation group. Many inflammatory cel s and apoptotic neurons were found in model group. There were few inflammatory cel s and apoptotic neurons in hydrogen-rich saline group. Hydrogen-rich saline can prevent the apoptosis of spinal cord anterior-horn motor neurons in rabbits with spinal cord ischemia-reperfusion injury, and the underlying mechanism is associated with antioxidative effect.

BACKGROUND: The concern over the use of electroencephalogram (EEG)diagnosis and biofeedback training as a viable option for children with attention deficit hyperactivity disorder(ADHD) has grown gradually.OBJECTIVE: To evaluate the diagnostic accuracy and therapeutic efficacy of A620 EEG system to ADHD children.DESIGN: Prospective observation and comparative study on ADHD children.SETTING: Psychological department of a municipal hospital.PARTICIPANTS: From October 2003 to May 2004, 113 outpatient children in Psychology Hyperactivity Department of the Central Hospital of Anshan City were selected. Inclusion criteria: 6 to 14-year-old outpatient children in Hyperactivity Department. Exclusion criteria: nervous system organic diseases, pervasive developmental disorder(PDD), mental retardation, epilepsy, psychotic disorder, acoustical and visual abnormalities,etc. Of all the ADHD children, 88 were male and 25 were female, with the mean age of(10 ± 3) years.METHODS: A620 EEG system was applied to examine the 113 participants. According to the Diagnostic Criteria for ADHD in Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-Ⅳ), published by American Psychiatry Association, ADHD children were diagnosed and then the EEG diagnostic accuracy and specificity were calculated. The System was also used for biofeedback treatment on 27 ADHD children. Fluctuation of EEG θ/β value was measured both before and after treatment, and the change of hyperactivity index was investigated by Conners Parent Symptom Questionnaire as well.MAIN OUTCOME MEASURES: EEG θ/β value, Conners index of hyperactivity (CIH).RESULTS: The diagnostic sensitivity of EEG on ADHD was 83.58%, and the specificity of it was 82.61%; EEB θ/β value of post-treatment was 8.26 ±4.05, which decreased significantly compared with pre-treatment value (12.38 ± 7.96) ( t = 2. 39, P < 0.05); CIH was also dramatically declined from(24. 73 ± 10. 96) (pre-treatment) to( 12.05 ± 8.63)(post-treatment) ( t= 4.72, P < 0. 01 ).CONCLUSION: EEG can be used as an accessory method in ADHD diagnosis due to its high sensitivity and specificity. Abnormalities of brainwave and hyperactivities of ADHD patients can be greatly ameliorated by EEGbiofeedback treatment.
