Objective To investigate the lesion of podocyte and the expression of renal integrin-hnked kinase (ILK) in a diet-induced hyperlipidemic model of rats. Methods Thirty-six 6-8 week-old female Wistar rats were randomly assigned into three groups, high-fat diet group, rats in each group were sacrificed at the 4th and 10th week respectively. The levels of serum cholesterol and triglyceride were determined by enzymic method. The morphology of podocyte was observed and photographed with electron microscope. The expression of ILK mRNA was determined by RT-PCR. The expressions of ILK and desmin protein were determined by Western blot analysis. The distribution of ILK in renal tissue was examined by immunohistochemieal staining. Results Levels of serum cholesterol and triglyceride, the expression of desmin, renal ILK mRNA and protein, as well as the foot process effacement were significantly up-regulated in both high-fat diet group and simvastatin group as compared with control group. However, all of the above parameters were ameliorated in simvastatin group as compared with high-fat diet group (P<0.01). ILK was mainly expressed in glomendar podocytes and renal tubular cells by immunohistochemical staining, and its change was similar to the results detected by Western blot analysis in each group. A positive correlation was found between ILK protein expression and desmin expression in renal tissue(r=0.93107, R2=0.8669, P<0.01). Conclusions Podocyte lesion can be induced by high-fat diet, which is correlated with over-expression of renal ILK. Simvastatin may play an important role in protecting against podocyte injury induced by hyperlipoidemia, properly through down-regulating ILK expression in renal tissue.

Objective To study the reliability and validity of the Chinese version of the dynamic occupational therapy cognitive assessment for children (DOTCA-Ch).Methods The English version of the DOTCA-Ch was translated into Chinese. One hundred and nine students from the city of Jiamusi were assessed with the Chinese Binet intelligence test and the DOTCA-Ch. Intra-class correlation coefficients (ICCs) were used in inter-rater and intra-rater reliability assessments. Cronbach's alpha coefficient was used to assess internal consistency. Factor analysis was used to assess construct validity. Pearson correlation coefficients were used in assessing criterion-related validity. Results The total ICC of the DOTCA-Ch was 0. 892. Cronbach's alpha coefficients for the subtests were orientation 0. 713 ; spatial perception 0. 793 ; praxis 0. 850 ; visuomotor construction 0. 844 and thinking operations 0. 630. The ICC for intra-rater reliability was 0. 991 and for inter-rater reliability it was 0. 989. Using the Binet intelligence test as a benchmark, the Pearson correlation coefficient between the IQ values and the total DOTCA-Ch scores was 0. 872 for 6 year-olds, but 0. 870 for 11 and 12 yearolds. Factor analysis revealed an acceptable set of 5 common factors. Their cumulative contribution was 67％.Conclusions The Chinese version of the DOTCA-Ch is reliable and valid. It can be used as an effective measuring tool to evaluate children's cognitive functioning.

ObjectiveTo study change of aminoacid content in the brain of newborn rabbits with bilirubin encephalopathy. MethodsNewborn rabbits (3-5 days after birth) with bilirubin encephalopathy were induced by administration intra peritoneally with bilirubin (200mg/kg). Aminoacid content in brain were analysed by Hitachi 835 50 type aminoacid analysis instrument.ResultsThe content of glutamate and aspartate in brain tissue with bilirubin encephopathy decrease; GABA, alanine, tyrosine, valine and pheny lalanine increase. ConclusionsThe change of content of neurotransmitters in brain indicates that excitotoxicity of EAAs may contribute to the bilirubin encephalopathy. The increase of non neurotransmitters level proves that bilirubin may inhibit the biologic composition of protein in brain.

Objective To explore the mental health and personality traits of the parents of cerebral palsy children. Methods 128 parents of cerebral palsy children and other 128 parents of healthy children were investigated with the Symptom Check List-90 (SCL-90), Eysenck Personality Questionnaire (EPQ). Results The scores of SCL-90 were more in the parents of cerebral palsy children, especially in the factors of somatization, obsession, depression, anxiety, and paranoid (P<0.01). The personality traits characterized as introversion (P<0.05) and neuroticism (P<0.01). The multiple regression showed that some factors of SCL-90 were related with the personality of neuroticism. Conclusion The mental health of the parents of children with cerebral palsy are poor, which may be related with the personality of neuroticism.

Objectives To investigate the clinical characteristics of hypoglycemic brain damage, and to assess the ifndings of amplitude-integrated electroencephalography (aEEG) and its predictive value in hypoglycemic brain damage. Methods Twenty-four neonates diagnosed with hypoglycaemia were selected. 12-hour continuous aEEG recordings were performed on the day when hypoglycaemia was diagnosed and second aEEG tracings was performed on the same day or the day after. The variability of aEEG background, appearance of sleep-wake cycling, bandwidth span and amplitude of lower border were analysed and compared with the results of brain MRI. Results Different degrees of epileptic seizures were found in neonates with severe hypoglycemic brain damage and were persisted after the blood sugar was corrected. aEEG in hypoglycemic brain damage was characterized by calyptriform or jagged epileptiform activity, disappearance of the sleep-wake cycle, but little impact on amplitude of lower border and bandwidth span. The recovery of sleep-wake cycle was a sign of brain function recovery. The aEEG and MRI had a good consistency in monitoring the hypoglycemic brain damage. Conclusions aEEG have signiifcant changes in hypoglycemic brain damage and can be used to monitor dynamically hypo-glycemic brain damage.

Objective To study the clinic value of brain edema detected by ultrasound examination in high risk term infants. Meth-ods The study group included 140 term infants who were found having brain edema in cranial ultrasound examinations. 152 term infants with normal ultrasound scan were selected as a control group. The risk factors of brain edema were collected, and univariate analysis and multivariate logistic regression analysis were performed. Results (1) There was no difference of incidence of brain edema between the infants with or without maternal ill historys, fetal distress or hypoalbuminemia, with P > 0.05. (2) In the univariate regression model, as-phyxia,hypoxic -ischemic encephalopathy (HIE) ,ventilation and metabolic acidosis were associated with an increased risk of brain ede-ma. In the multivariate logistic regression model, HIE was associated with a greater risk of brain edema and ventilation was possibly asso-ciated with brain edema. Conclusion Brain edema detected by ultrasound examination in high risk term infants has close relationship with HIE. It suggest that there is a consistency between ultrasound results and clinic situation. The detection of brain edema by ultrasound can assist doctor in clinic practice.

Objective To study the validity of Dynamic Occupational Therapy Cognitive Assessment for Children (DOTCA-Ch) on the cognitive function of children with cerebral palsy. Methods 30 children with cerebral palsy were assessed with DOTCA-Ch and Chinese Binet Test of Intelligence by trained rehabilitation medicine graduates within 1 week. The correlation between these tests were analyzed. Results The total DOTCA-Ch scores, spatial orientation and thought operation function were strongly correlated with IQ, while spatial perception,praxis and optomotor tissue were slightly correlated with IQ. Conclusion DOTCA-Ch can comprehensively assess the cognitive function of children with cerebral palsy.

Objective To observe the application of elastic bandage in cerebral palsy with knee hyperextension. Methods 20 spastic diplegia children were radomly divided into control group and experimental group with 10 cases in each group. Both of them received conventional rehabilitation, including exercise therapy, occupational therapy and speech therapy. The experimental group worn elastic bandages additionally when orthostatic walk preparing and walking training. The knee range of motion (ROM), D and E zones of Gross Motor Function Measure (GMFM) were evaluated before and 3 months after treatment. Results The ROM decreased, and the score of GMFM increased after treatment in both groups (P<0.01), especially in the experimental group (P<0.01). Conclusion The elastic bandage can improve the knee function and the gross motor function of cerebral palsy children with knee hyperextension.

Objective To study the effect of brain function biofeedback on children with spastic cerebral palsy following attention deficit disorder. Methods 44 children with spastic cerebral palsy were divided into 2 groups: 23 cases in observation group and 21in control group. The routine rehabilitation including physical therapy, occupational therapy, sensory integration, speech therapy and traditional Chinese medicine were used in two groups, while at the same time EEG biofeedback therapy was used in the observation group 5 times a week for 3 months. Chinese Binet Intelligence Scale (CBIS) and The Test of Variables of Attention (TOVA) were used to assess the effect before and after treatment. Results After the treatment, the intellectual level of the observation group significantly improved (P<0.01), omissions significantly reduced (P<0.01), error number was lower (P<0.05), reaction time was significantly shorter(P<0.01), mutation rate was significantly lower (P<0.01); while the intellectual level of the control group didn't significantly improve (P>0.05), omissions and reaction time significantly reduced (P<0.01), there was not obvious difference in error number and the mutation (P>0.05). Conclusion Brain function biofeedback can effectively improve attention disorder in children with spastic cerebral palsy.
