56 school-aged children with epilepsy and 37 normal ones of the same gender,age and educational level were selected. All the subjects' parents completed the child adaptive behavior scale, the mutiple stepwise linear re-gression was used to explore the impact of epilepsy related factors on social adaptive function. The social adaptive function of school-aged children with epilepsy faulty is affected by seizure frequence,gender,age,epilepsy control, clinical course,and the number of antiepileptic drugs.

Objective To establish a system for rapidly detecting single nucleotide polymorphisms (SNPs) in mitochondrial DNA (mtDNA) using hybridization probes and melting temperature (Tm) curve analysis. This technique is suitable for population-based studies on the interaction between genetic factors and environmental exposures and the risk of Parkinson's disease (PD). Methods mtDNA was extracted from the blood. Rapid polymerase chain reaction (PCR) and melting curve analyses were performed with primers and fluorochrome-labeled probes on a LightCycler. Genotyping of 10 SNPs was based on the analysis of allele-specific Tm of detection probes. The results of melting curve analyses were verified by sequencing all 150 PCR products. Results Real-time monitoring showed optimal PCR amplification of each mtDNA fragment. The changes at nucleotide positions 1719, 4580, 7028, 8251, 9055, 10398, 12308, 13368, 13708, 16391 from wild-type to mutant genotype resulted in 6.51, 8.29, 3.26, 7.82, 4.79, 2.84, 2.73, 9.04, 8.53, 9.52℃ decline in Tm of the detection probes respectively. Genotyping of all detected genes was verified by 100% correspondence with the results of sequencing. Conclusion A rapid and reliable detection system for identifying mitochondrial polymorphisms and haplotypes has ben developed based on hybridization probe technology. This method may be suitable for mitochondrial genotyping of samples from large-scale epidemiology studies and may prove useful for exploring the molecular etiopathogenesis of PD, identifying markers of genetic susceptibility, and protecting susceptible individuals from PD.

Objective To explore the effect of BPDE on the expression of N-Ras in the human bronchial epithelial cell line. Methods The levels of mRNA and protein expression in BPDE transformed 16HBE cells(16HBE-T) and untransformed control 16HBE cells(16HBE-N) were examined by using RT-PCR and Western blot. Locations and expression levels of protein in both kinds of cells were analyzed by immunocytochemical method. Results Compared with 16HBE-N, the levels of mRNA and protein of N-Ras significantly increased to 3.616 and 1.600 times in 16HBE-T. Immunocytochemical method showed N-Ras protein in 16HBE-T and 16HBE-N expressed in the cytomembrane and cytoplasm, but the expression level of protein in 16HBE-T was significantly higher than that in 16HBE-N. Conclusion The up-regulated expression of N-Ras oncogene may play an important role in the malignant transformation of 16HBE induced by BPDE

Mechanisms responsible for the aging related memory and learning deficit may involve in synaptic morphology and fanction deterioration in hippocampas, changes of central neurotransmitter systems、 brain intracellular calcium ions concentration、 gene expression and neurotrophasthemic etc. The mechanisms of aging related attenuation in memory and learning is summarized.

OBJECTIVE:To study the effect of the extracts of Paederia scandens (EPS) on acute gouty arthritis induced by monosodium urate in rats. METHODS: Monosodium urate crystals were used to establish gouty arthritis model in rats, with ankle joints' swelling degree at different time after modeling measured using paw volume measuring meter and gaits of rats scored at 24h after modeling. Pathological changes of articular tissues of rats were observed with HE staining and TNF-? and IL-1? levels were monitored by Radioimmunoassay. RESULTS:EPS could significantly inhibit joint swelling of rats and improve the gaits; histopathologically, EPS could abate tissue swelling of ankle joints, reduce inflammatory cell infiltration of articlar tissues and improve the pathological changes of synovial membranes. Radiommunoassay revealed that EPS could reduce levels of TNF-? and IL-1? in rats' synovial membranes. CONCLUSION:EPS have remarkable efficacy in improving symptoms of acute gouty arthritis induced by monosodium urate crystals in rats, which might be related to its inhibition on levels of IL-1? and TNF-?.

OBJECTIVE:To explore the effects of bioactive compounds from entomogenous fungi(BCEF0083)on hip-pocampus neurons and mRNA expression of BDNF in chronic stress depression rat models.METHODS:The selected rats were randomly divided into control group,model group,moclobemide20mg/kg group,and BCEF0083100,50,25mg/kg groups.The change in hippocampus neuron numbers were observed by HE staining and mRNA expression of BDNF was detected with RT-PCR.RESULTS:BCEF0083could increase the neuron numbers and up-regulate the expression of BDNF mRNA in hippocampus.CONCLUSION:The antidepressant effect of BCEF0083in chronic stress depression rat models is probably re-lated to the increase in hippocampus neuron numbers and up-regulation of expression of BDNF mRNA in hippocampus.

OBJECTIVE: To study the antidepressant effects of total flavone of A( TFA) on post stroke depression ( PSD) in rats. METHODS: Middle cerebral artery occlusion ( MCAO) followed by isolation feed and irritable stimuli was used to induce PSD. Behaviours of rats were detected by open- field test . The effects of TFA on the indexes of hemorheology and brain homogenate lipid peroxidation were also tested. RESULTS: TFA could increase the crossing and rearing scores in open- field test, inhibit the elevation of whole blood viscosity as well as plasma viscosity at high- middle- low shear rates, increase the erythrocyte deformation, enhance the activities of Superoxide Dismutase ( SOD) and Glutathione Peroxidase ( GSH- Px) , and reduce Malondialdehyde ( MDA) content in brain homogenate in PSD in rats. CONCLUSIONS: TFA produces an antidepressant- like effect in PSD rats. This mechanism may be in association with attenuating hemorheological parameters and decreasing lipid peroxidative damage.
