Clinical Analysis and Gene Mutation Screening of Voltage-Gated Sodium Channel ?1 Subunit in 2 Generalized Epilepsy with Febrile Seizures Plus Families / 实用儿科临床杂志

Objective To explore the mutation of voltage-gated sodium channel ?1 subunit(SCN1B)gene in Chinese Han families with generalized epilepsy with febrile seizures plus(GEFS+).Methods Two families pedigrees were established and disease history,physical examination were collected in order to analyze the mode of inheritance.The mutation sites of reported SCN1B gene exon 3-(C46T,G47A,C156G)were detected by polymerase chain reaction sequence special primers(PCR-SSP)method after genomic DNA were extracted.Results There were 13 patients in the 2 families,all were Han people and 9 cases were living.The results showed the mode of inheritance basically corresponds with autosomal dominant inheritance complicated with incomplete penetrance,and leaded to different kinds of phenotype.The mutation sites of SCN1B gene exon 3 were detected by using PCR-SSP method,and heterozygote was not found,and point mutations were also not found in the 2 families.Conclusions GEFS+ is a complex disorder with genetic heterogeneity.There were no gene mutations of SCNIB in the 2 GEFS+ families,which might suggets the possibility of insufficient samples as the patients came from Henan province and the possibility of differences from races and regions of other countries.

Follow-Up Study of One Family with Generalized Epilepsy with Febrile Seizures Plus / 实用儿科临床杂志

Objective To investigate the clinical significance of generalized epilepsy with febrile seizures plus(GEFS+ ). Methods The data of one family with GEFS+ were retrospectively analyzed by studying clinical manifestations, physical examinations, electroencephalogram(EEG), 24 hours dynamic EEG monitoring, et al. Some of the patients were examined by CT. Results Ⅳ 12, her chief complaints when admitted to hospital were frequent spasm for 3 days. She began to appear febrile seizures (FS) from 8 months after birth, and frequent generalized tonic - clonic FS appeared during that time. There were 36 people in 5 generations of the family including 14 patients (8 males and 6 females) ,aged from 4 years and 5 months to 82 years. FS presented in 8 cases (Ⅱ 2, Ⅲ1, Ⅲ4, Ⅲ6, Ⅳ1, Ⅳ11, Ⅳ17, Ⅴ2),febrile seizures plus(FS +) in 4 cases ( Ⅳ2, Ⅳ12, Ⅳ13, Ⅳ14), ES + and absence seizures in 1 case ( Ⅴ1 ), uncertain type in 1 case (Ⅰ2). The results of EEG indicated that 12 cases were normal and 4 cases with FS+ and 1 case with absence seizures had epileptic discharges. Apart form Ⅳ13, Ⅳ14 who were treated with magnesium valproate, the dosage for the other patients decreased, or medicine terminated or without medicine, and all the patients had no recurrence of seizures. The intelligence, movement development and neurological examinations of the family were all normal. Head CT scan of 3 cases were normal. Conclusions GEFS+ is autosomal dominant inheritance disease with conspicuous genetic heterogeneity and phenotypic heterogeneity. The apprehension of GEFS+ plays an important role in diagnosis and differential diagnosis of epilepsy in childhood.

Effect of L-Carnosine on Neuronal Cell Apoptosis in Young Rats with Febrile Seizures / 实用儿科临床杂志

Objective To explore the effect of L-carnosine on neuronal cell apoptosis in young rats with experimental febrile seizures(FS).Methods Forty 15-day SD rats were randomly divided into intervention group(n=30)and FS group(n=10).Warm water was used to induce 10 times FS.The intervention group was divided into E,G and H group,10 rats in each group.Intraperitoneal injection of L-carnosine(250 mg/kg)was separately given to the rats in E group,G group and H group respectively after 30,60 and 120 min of seizure.FS group were induced FS,but they were not given intervention.The rats were sacrificed at 12 hours after the last seizure.Neuronal cell apoptosis was determined by terminal eoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)in situ cell death kit.TUNEL positive cells were stained and counted as apoptosis in hippocampus and cortex.Ultrastructural changes of apoptosis neurons were observed under the electron microscope.Results The neuronal cells apoptosis count was 25.37?1.95 in FS group,12.36?1.13 in E group,17.85?2.04 in G group,and 22.69?2.69 in H group.Neuronal apoptosis of FS group was apparently higher than that of interventional groups(F=10.75 P0.05).Under the electron microscope,neuronal damage on hippocampal CA1 area and dentate gyrus of FS group and H group was obviously higher than that of E group.Conclusions Early injection of L-carnosine would not only relieve neuronal apoptosis of repeated FS,but also play a role in the protection of neuronal cells.

Change and Significance of Soluble Intercellular Adhesion Molecule-1 in Cerebro spinal Fluid of Bacterial Meningitis Induced by Escherichia Coli in Rabbits / 实用儿科临床杂志

Objective To investigate the changes and significance of concentration of soluble intercellular adhesion molecule-1(sICAM-1) in cerebrospinal fluid (CSF) of bacterial meningitis(BM) in rabbits. Methods A total of 36 rabbits were randomly divided into m eningitis group, meningitis cefotaxime-treated group and control group. BM indu ced by escherichia coli(Ec) via cerebellomedullary cistern inoculated. Normal sa line was injected in control group. CSF was sampled in different time. The conce ntration of CSF sICAM-1 was detected by ELISA.Results 1.There was a low concentration of sICAM-1 in CSF in 85 percent of normal rabbi ts.2.In meningitis group, there was a sharp rise in the concentration of CSF sIC AM-1 at 6 hours after Ec was inoculated, reached a peak level at 12 hours, and t here was higher concentration of CSF sICAM-1 between 6 and 24 hour than that at 0 hour.3.In meningitis cefotaxime-treated group, the concentration of CSF sICAM -1 at 6 hour and 12 hours was similar to meningitis group, the time that get pe ak level was at 24 hours that at 12 hours after making use of antimicrobial agen t.The peak level was higher than meningitis group. The concentration of CSF sICA M-1 decreased markedly at 48 hours that made use of antimicrobial agent 36 hour s later,but the concentration was still higher than the peak level of meningitis group.Afterwards, with the time of making use of antimicrobial agent lengthened ,the concentration of CSF sICAM-1 decreased gradually.4.Experimental results in dicated by correlating analysis to these data that there was positive correlatio n in the concentration of CSF sICAM-1 with the brain water content.Conclusions sICAM-1 participates in the pathological process of BM, and contributes to the damage of blood brain barrier and the formation of brain edema.There is importan t significance that drugs which can resist the discharge of sICAM-1 will be impl ied.
