Objective To evaluate the efficacy and safety of topiramate(TPM) as add - on drug treating infants with severe epilepsy. Methods We performed prospective label add - on study in 12 infants (aged 4 to 19 months) with sever seizures of different types. TPM was add - on one or more other baseline drugs and the efficacy was evaluated according to seizure type and frequency Results TPM initiated in a daily dose of 0.5 - 1 0 mg/kg, followed by a 1 - 2 weeks titration on the increase of 0 5 - 1.0 mg/kg up to a maximum daily dose of 4 - 10 mg/kg. After a mean period of 6 2 months (range 3- 13 montks), Total efficacy was 75 % and 50 % were controlled completely. Seizure frequency was unchanged in 3 patients (25 % ). As for seizure type, TPM was more effective in complex partial as compared with generalized tonic-conic seizures. Mild adverse events were present in 3 patients (25 %), represented hypersonia, fever and decreased speech. Conclusions TPM may be a available drug in infants with severe epilepsy. It is safe, with mild adverse effect in fewer patients.JAppl Clin Pediatr,2004,19(11):986-987

The purpose of this study is to investigate the enantioselectivity of norgestrel (NG) transdermal permeation and the potential influence of linalool and lipids on the enantioselectivity. In vitro skin permeation studies of NG across the excised rat skins were performed with Valia-Chien diffusion cells, and the permeation samples were analyzed by enantioselective HPLC. The possible enantioselective permeation of NG across intact rat back skin and lipids extracted rat back skin and the influence of linalool were evaluated. The skin permeation rate of dl-NG was two times higher than that of l-NG when donor solutions (EtOH/H2O 2 : 8, v/v) containing l-NG or dl-NG. It may be mainly attributed to the solubility discrepancy between enantiomer and racemate. The enantioselective permeation of dl-NG across intact rat skin was observed when the donor solutions containing dl-linalool. The permeation flux of l-NG was 22% higher than that of d-NG. But interestingly, the enantioselective permeation of dl-NG disappeared under the same experimental condition except that the lipid extracted rat skin was used. Attenuated total reflection-fourier transform infrared spectroscopy analysis of stratum corneum showed that the wave number for asymmetric CH2 stretching vibrations of lipids treated with dl-linalool was greater than that of the control. The results indicated that the enantioselective permeation of NG may be contributed by the interaction between dl-linalool and lipids. More than half of lipids were composed of ceramides. The stereospecific interaction maybe existed among chiral enhancer (linalool), lipids (ceramides) and/or chiral drugs (NG).

Objective Diabetic mice models were established.Hearts were separated from the body,reperfused after ischemia,and disposed of with the extraneous calcitonin gene-ralated peptide (CGRP),to prove if the CGRP had protective effect on the early-staged diabetic mice with cardiac ischemia.Method ICR mice were injected with Streptozocins intraperitoneally to establish diabetic model.The model mice and the normal mice were randomly divided into 4 groups:two diabetic groups,two control groups.Hearts of the experimental mice were taken out from the chest cavity alive,and hanged on the Langendorff steadily for 30min.Western blot and radioimmunoassay techniques were used to test expression of Vanilloid receptor(VR1) and CGRP in myocardic tissue;Madlab system was used to test the cardiac function,which including left ventricular end-diastolic pressure (LVEDP),left ventricular developed pressure (LVDP),heart rate (HR),and coronary artery flow (CF),in the process of ischemic reperfusion,And ELISA assay kit was used to measure the concentration of the lactate dehydrogenase (LDH) in perfusion fluid collected from the heart.Result Expressions of VR1 and CGRP in diabetic hearts were significantly lower than those in normal ones 2 weeks later(P<0.01).By comparing with normal hearts,diabetic hearts had higher LVEDP and CF (P<0.05),and lower LVDP and HR(P<0.05).However,release of LDH were lower than normal ones (P<0.05).Predisposition of normal and diabetic hearts with CGRP can improve the cardiac function after ischemie injury.And the beneficial effect was more profound in early-staged diabetic hearts than in normal ones.Conclusion The diabetes disease(DM) can impair the expression of CGRP in myocardiac tissue.The extraneous CGRP may exert more potent protective effect on cardiac function in the early-staged diabetic heart.

Objective To investigate the clinic characters and diagnosis of superficial siderosis in the central nervous system (SSCN).Methods One patient was systematically studied by the authors. Results SSCN was a rare entity,resulting in the deposition of ferric pigments and ions on the surface of the central nervous system.The clinical features included progressive sensorineural hearing loss,cerebellar ataxia and pyramidal sign,widespread hypointensity band at surfaces of the cerebral or cerebellar hemispheres,the brain stem and the spinal cord on Gradient Echo T_2~*-weighted images (GRE-T_2~* WI) of MR,elevation of the levels of ferritin in the cerebrospinal fluid.Conclusions This disease can be identified at early stage with history and physical examination.GRE-T_2~* WI and some related cerebrospinal fluid tests will contribute to diagnosis.

Objective To determine the value of Magnetic resonance imaging(MRI)technique on diagnosis of adrenal medulla hyperplasia model rats confirmed by pathology study.Methods Sixty male SD rats were divided into 6 groups randomly,10 rats in each group.As experiment group,A,B,C groups were subcutaneously injected with reserpine(0.4 mg?kg~(-1)?d~(-1))from the beginning to 40,60,80 days respectively.As compare,the control groups(a,b,c group)were only injected with sodium chloride simultaneously.MRI technique and pathology study were performed for all the subjects on 40,60,and 80 days respectively.Results The percent of medulla were higher in B and C groups than that in b and c groups respectively[(34.3?5.8)% vs.(25.7?8.9)%,t=2.462,P

Objective To analyze the complications due to CT-guided transthoracic aspiration biopsy for pulmonary lesions and discuss the role of puncture skill for reducing the complications.Methods CT- guided transthoracic aspiration biopsy was performed in 116 patients with intrapulmonary parenchymal occupied lesions from June 2006 to June 2007 in our hospital.The complications and the whole process of puncture were analyzed to obtain the experience for reducing the occurrence of complications.Results CT-guided transthoracic aspiration biopsy was succeeded in all 116 cases.The major complications included pneumothorax (15.51%),puncture tract hemorrhage(10.34%),hemoptysis(4.31%)and others(1.72%).Only 1 case of pneumothorax was treated by closed thoracic drainage and no specific treatment for others.Conclusion CT- guided transthoracic aspiration biopsy for pulmonary lesions is an efficient and safe diagnostic modality.The criteria for reducing the complications are associated with accurate localization,the correct breath training and evaluation of lesion before the operation.(J Intervent Radiol,2007,16:847-849)

Objective To observe the effect of magnesium valproate sustained release tablets on children with epilepsy and its effects on cognitive function.Methods Magnesium valproate sustained release tablets were conducted on 38 cases.Close attention was paid to both the degree of paroxysm control and side effects during treatment while periodic examinations on liver function and blood routine were also conducted.The intelligence and P300 of children with epileptics were respectively measured before and after 6-month treatment.Forty children of control group was set up.Results Eighteen cases were totally under controlled(47.4%),11 obviously effect(28.9%),6 effect(15.8%).The total effective rate in total was 92.1%.Obvious differencees in intelligence between children with epileptics and control group before and after 6-month treatment were observed(all P0.05).Conclusions Magnesium valproate sustained release tablets is a new type of broad-spectrum anti-epileptic drug,which has an obvious effect on treatment of children with epileptic without any obvious adverse reaction.It imposes little influence on children′s cognitive function.
