Objective To explore the effect and adverse reaction of topiramate(TPM) on treating Lennox-Gastaut syndrome(LGS)(including therapeutic alliance or single ). Methods Twenty-four cases with LGS whose attacks could not be controlled by re-(gular) therapy were selected.TPM was gradually increased from low dosage till its showing effect or untolerant adverse reaction.Results Two cases were excluded because of adverse reaction and increase of attacks. The remained cases were followed up from 6 months to 15 months (average: 9 months). The total effective rate was 82.6%, 11 cases accounting for 45.8% free of attack. The tonic-clonic seizure reduced more than 50% accounting for 82.2%, the full control accounting for 66.7%. The myoclonic seizure reduced more than 50% accounting for 81.8%,the full control accounting for 58.8%.The atypical absence seizure reduced more than 50% accounting for 81.8%, the full control accounting for 63.6%. The maximum effect occurred about 2-40 weeks following TPM used, the dosage about 2-10 mg/(kg?d).The adverse reaction included anorexia (8 cases), language disorder (5 cases), drowsiness (4 cases), decrease of anamnesis (3 cases), weight loss or unchanged(3 cases), inattention (3 cases), depression (3 cases), mental bradypraxia (2 cases ), skin damage (1 case), stupor (1 case), gross hematuria(1 case).The hepatic and renal function were normal during therapy. Conclusion TPM is a new, broad-spectrum, effective and safe antiepileptics drug on treating LGS.

Objective To search for the normal value and developmental regular rule of motor norve conduction in children.Methods One hundred and fourty-nine children aged from 0 to 14 years old were divided into 7 groups in accordance with age. There were 19 pecrsons aged from 20 to 35 years old in adult group. The motor nerve conduction function of median nerve, ulnar perve, tibial nerve and peroneal nerve of every suhject was determined by nerve evoked potential meter.Results The terminal latency of action potential of every nerve is decreased along with growing up of age before 6 years old and increased after 6 years old. The conduction velocity of ulnar nerve is the fastest,then the peroneal nerve and median nerve, that of tibial nerve is the slowest. Median nerve development quicken after 3 months of birth and approch ulnar nerve at the time of 3 years old. Tibial nerye get into fast development period from 3 months to 1 years old and catch up peroneal nerve. The conduction velocity of every nerve extend to adult level in th period of 3~6 years old.Conclusion The every parameler of nervous conduction has a great difference of age in the period of child,particularly in that of infancy. therefore, the normal values should be set up in accordance with proper age groups. This study shows that it's suitable to divide groups in accordance with new-born, 3 and 6 months, 1, 3 and 6 years old. Adult criterion should be used in the children dbove 6 years old.

Objective To explore the different influence of antiepileptic drugs(AEDs)at therapeutic levels to the maturation of brain.Methods 180 healthy Sprague-Dawley(SD)rats were divided into infant and adult group.Each age group was administered with PB,CNP,VPA,TPM or normal saline respectively in persistent 5 weeks.The steady-state plasma concentrations of AEDs at the experimental dosage were coincided with the range of clinical therapeutic concentrations.After AEDs withdrawed,the effects of AEDs on cognitive function were assessed by Morris water maze and two-way shuttle box at different time points.Body and brain weight were got immediately when the rats were sacrificed.Histological changes of brain were observed by HE staining,Nissl staining and transmission electron microscopy.Results(1) For immature rats,1 day or 14 days after AEDs withdrawed,there were significant differences between groups exposed to PB or CNP and control group in escape response latency(ERL)in the two-way shuttle box.Even after one month ERLs of immature rats receiving CNP((6.05?2.04)s)or PB((5.81? 1.75)s)were still longer than that of untreated controls((4.75?2.43)s,P

Allergic rhinitis and rhinosinusitis often complicate with asthma,and their relationship has long been investigated.From the view of epidemiology,all of these three diseases have higher prevalence,complicate with each other,are risk factors and prognostic factors for each other.Besides,they share common in anatomy and pathophysiology.In this paper,the interrelationship among allergic rhinitis,rhinosinusitis and asthma in pathogenesis is discussed.
