Objective To explore the change of degrade of clonazepam in serum with single and repeated - dose administration in children with seizure, and find a reasonable method for using the clonazepam. Methods Children with seizures were divided into single - dose paradigam, repeated - dose paradigam, and decreased - dose paradigam. The concentration of CZP in serum was determined by high performance liquid chromatography( HPLC). Results The serum concentrations of clanazepain in single - dose paradigam were (101.9?12.1),(76.9 ? 5.8),(50.7?2.9),(30.9?5.4),(21.5?6.8)?g/L,the time point that the blood samples collected were 15,30,60,120 and 480 min. The serum concentrations in repeated - dose paradigam were (97. 2 ? 6. 1),(130.4? 13. 4), (99. 4 ? 9.8),(79.6?2.4)?g/L,in decreased-dose paradigam were( 101.1 ?13.1),(123.1 ?6. 6), (99.4 ?9. 8), (79. 3 ? 2. 2)?g/L,in these two groups,the time point were 15,45,60 and 120 min. Conclusion Repeated administration of CZP with decreased dose may increase its effectiveness in treatment without substantially increasing toxicity.

0.05).The third day after SE,the expressions of MVP in CA1 and CA3 in adult rats experiment group increased,and in CA3,the value reached up to(4.0?1.41)in adult experiment group,which had significant differences compared with control groups(P

OBJECTIVE:To survey and evaluate the present situation and trends of antidiabetic agents used in hospitals of southwest China so as to provide information for the production,sale and consumption units.METHODS:To investigate the antidiabetic agents used in60hospitals of southwest China during the period2000～2002in respect to the sum of money of consumption,Kinds of drugs,DDDs and DDC.RESULTS:In recent3years,the annual increasing rates of consumption of oral antidiabetic agents and insulin injection were14.12%and42.09%,the proportions of costs for the oral antidiabetic agents and insulin injections in total consumption of antidiabetic agents were67.20%and32.78%respectively.CONCLUSION:The use of insulin is increasing quickly and the new dosage has developmental future.The Metformin and Glipizide are the important oral antidiabetic agents.

Objective Study the ideal drug to treat age depen de nt epileptic ncephalopathy (ADEE) in earlier period. Methods fi fty-four patients with ADEE were studyed.21 cases used with single topiramate(T PM) as initial treatment and 27 cases used with TPM and antiepileptic drug(AEDs ) .Results Seizure was fully controlled in 11 patients with TPM m onotherapy and in 4 patients with TPM as adjunction.The differences was signif icant(P

Objective To investigate clinical feature,diagnosis and prognosis of eosinophilic gastroenteritis(EG),and to analyze the causes of misdiagnosis.Methods Eleven children diagnosed as EG were studied.Their history,clinical manifestations,laboratory tests and endoscopies and treatment,follow-up data were analyzed.The data were analyzed by SPSS 10.0 software.Results 1.The children with EG usually had abdominal pain(5 cases),diarrhea(7 cases),hemafecia(5 cases) and sometimes with fever(2 cases).2.EG and allergy in children was closely related with disease(54.55%).3.Peripheral blood eosinophil(EOS) count increased significantly,and declined when symptoms eased(18.18%).4.Endoscopic manifestations were not specific,the mucosa could see sheet erosion,shallow ulcers,congestive spots or bleeding spots,mainly in antrum,duodenum,terminal ileum,ileocecal junction.The biopsy showed that a large number of EOS infiltration.5.Imaging were not specific,CT or gastrointestinal barium meal examination did not show special often(90.91%).When muscular wall was affected(9.09%),imaging presentations of EG could be partly obstructive.6.Glucocorticoid therapy could relieve symptoms and EOS.Symptoms probably recured by good prognosis.7.EG was a self-limiting allergic diseases,although the attack may be repeated.After long-term follow-up,most had good prognosis and without malignant.Conclusions Clinical and endoscopic presentations of EG are not specific,therefore the presence of EOS in gastrointestinal mucosa strongly indicate the diagnosis.It was easy to misdiagnosis.Biopsy pathology and cli-nical characteristics are the key to diagnosis.

Objective To explore the expression of c-Fos protein and character of mossy fiber sprouting(MFS) in hippocampus of rat with febrile seizures(FS).Methods Thirty-six 21-day-old male Sprague-Dawley rats were randomly divided into FS group,febrile control(FG) group and normal control(NG) group.FS was established by hyperthermal bath.Immune histochemistry and(Timm′s) staining were used to examine the expression of c-Fos protein in CA1 region and MFS in CA3 region of hippocampus.Results Excessive expression of c-Fos protein presented in the hippocampal CA1 region of FS group.The surface area percentage of c-Fos protein of FS group[(2.26?0.23)%] was higher than that of FG group[(1.08?0.19)%] and NG group[(0.71?0.14)%],there were significant difference between FS group and the other two groups(?~2=10.48 P

Interaction teaching model of teaching and studying exchanging,simulation scenes,and clinical scientific research training were developed in medical interns.With the helps of such teaching model,rapid progresses of studying interests,activi- ties,and abilities were found in such pediatric interns.Under grasping basic pediatrics knowledge according to teaching program, they all have multiple abilities of clinical practices,medical teaching,and scientific research to a degree.The interaction teaching model which regards student as principal part plays a very important role in the development of pediatric probation quality.
