ObjectiveTo study the method and effect of individualized education on children with learning disability (LD).Methods30 children during 7-10 year old in a local boarding elementary school were chosen and guided individually as the following: sensory integration dysfunction drill, subtle motion drill, life skills drill, cognitive capability drill, behavior therapy, game therapy, music therapy and parents education. One and a half year later, the index of Sensory Integration Rating Scales and study marks were determined and compared with that of the normal children.ResultsThere is not significant difference between the LD children and the normal ones in the sensory integration of behavior and the learning achievement.ConclusionIndividualized education is a valid approach improving the potentiality of the LD children\'s physiology and psychology.

A rapid and sensitive method based on biotin-avidin mediated competitive enzyme-linked immu nosorbent assay(BA-ELISA) was established for the determination of ketamine.The optimal concentration of coated antigen and anti-ketamine monoclonal antibody were found to be 2.0 and 10.2 mg/L.The concentra tions of biotinylated goat anti-mouse IgG(Biotin-IgG) and streptavidin-horseradish peroxidase(SA-HRP) were optimized and the optimum results were found to be 0.29 and 1.0 mg/L, respectively.The linear range of the presented method was from 0.1 to 1000 μg/L, and the limit of detection was found to be 0.03 μg/L.The recoveries of ketamine spiked in human serum and urine were between 94% and 102%.Comparing the result of traditional ELISA, the present BA-ELISA method had a lower detection limit for ketamine.The experimental results indicated that the present BA-ELISA method was specific and sensitive.

Chronic viral hepatitis B (CHB) is a major infectious disease greatly harmful to the health of Chinese people. Chinese medicine has its speciality and advantages in treating it depending syndrome-differentiation. The objectified researches regarding Chinese medical syndromes in CHB heretofore were reviewed in this article. Moreover, aiming at existing problems and taking the angle of "disease-syndrome combining" study, authors put forward research approach, and approaches for studying systemic biology based biological basis of Chinese medical syndrome in hepatitis B with reductionism and holism, cybernetics and system theories in combination.

Objective To explore clinical significence of soluble vascular cell adhesion molecular(SVCAM - 1),immunoglobulin A (IgA) anti- endothelial cells antibodies(AECA) in Henoch-Schonlein purpura(HSP) and their relationships. Methods SVCAM-1 were detected by ELISA between 55 cases with HSP (40 cases in acute stage and 15 cases in recovery) and 20 controls. Results The levels of serum SVCAM - 1 of the HSPN cases were significantly increased compared with the other HSP. In addition, the serum level of SVCAM - 1 in acute stage HSP children was significantly higher than that in recovery stage and normal controls. IgA AECA positive rate in HSPN was higher than that of without nephritis group. The level of serum SVCAM - 1 in IgA AECA positive children was higher than that of IgA AECA negative children. Conclusion SVCAM - 1 and IgA AECA may participate in the pathogegesis of HSP, and the level of molecule is correlated with the progress of HSP.

Objective To observe the behavior changes and synaptic reconstruction of brain and the impact of gastrodin in rats with epilepysy induced by pentylenetetrazole.Methods Fifty Wistar rats in growth(50-70 g) were randomly divided into 5 groups:control group,Pentylenetetrazole (PTZ) group,gastrodin high dose group,gastrodin low dose group and sodium valproate group,each group had 10 rats.According to Racine classification,the behavior changes of rats and the frequency were recorded.Conventional method was adopt to perfuse cordis, fix and extract the brain,and the immunohistochemistry was used to detect synaptophysin(P38) expression in the temporal lobe and hippocampus of the brain after 4 weeks.Results 1.Four weeks after pentylenetetrazole ignited the growth period rats,the attack-level of each experimental group through comparison with each other,there was statistically significant difference(?2=35.83 P0.05).Conclusions There are mossy fiber sprouting and the formation of synaptic reconstruction in temporal lobe and hippocampus of the growth period rats repea-tedly ignited by pentylenetetrazole.Gastrodin may play a role in the formation of antiepileptic obviously,and through decreasing the expression of P38,which can inhibit the formation of synaptic reconstruction,as control seizures indirectly.

Objective To evaluate the efficacy of radiosynovectomy with 32P colloid in haemophilic synovitis of adolescents. MethodsRadiosynovectomy with 32P colloid was primary performed on 26 male haemophilic patients(26 joints),whose average age was 16 years(11 to 21 years).The average dose of 32P colloid was 2.1 mCi(1.0 to 3.0 mCi). Results After 6-month interval,haemarthrosis was reduced by no less than 30% in 23 patients,with a total efficacy of 88.5%.The mean frequency of haemarthrosis was reduced from 1.9 per month of presynovectomy to 0.3 per month of postsynovectomy(P

Objectives: To evaluate mice as experimental animal for Chlamydia pneumoniae, a common cause of acute respiratory infections in human.　Methods: Intranasal inoculation of Icr mice with C. Pneumoniae induced a prolonged course of lung infection, as demonstrated by persistence of lung pathology(60 days).　Results: Icr mice were susceptible to C. pneumoniae. Lung pathology was characterized by patchy interstitial pneumonitis with predominately neutrophil leukocyte infiltration in the early(7 days) and lymphocytes infiltration in the later stages(14 days later) of infection.　Conclusions:Icr mice were susceptible to C. pneumoniae and the mouse model is useful for the investigation of the pathogenesis of C. pneumoniae infection.

ObjectiveTo investigate and compare the behavioral changes, neuron loss of hippocampus and mossy fiber sprouting between pilocarpine-induced status epilepticus (SE) model and pentylenetetrazole (PTZ) kindling model in rats.MethodsAfter two different epilepsy models were made, Vedio was adopted to observe the behavioral changes. Nissl staining and Neo-timms' staining were separately used to observe and compare the neuron loss of hippocampus and mossy fiber sprouting in the dentate gyrus (DG) at different time points during epileptogenisis.ResultsNo recurrent spontaneous seizure, no neuron loss and no mossy fiber sprouting were found in PTZ kindling model; whereas obvious neuron loss was found in CA1, CA3 of hippocampus and hilus of DG, and mossy fiber sprouting were found in pilocarpine model in parallel with recurrent spontaneous seizures. ConclusionPTZ kindling model resembles absence epilepsy in human, while pilocarpine-induced status epilepticus model resembles chronic temporal epilepsy in human. Neuron loss and mossy fiber sprouting may play an important role in epileptogenisis. Pilocarpine-induced epilepsy model can be regarded as an ideal chronic temporal epilepsy model.
