Objective To evaluate the long-term clinical efficacy and security of levetiracetam (Lev) as add-on therapy in patients with different types of epilepsies from an observational study.Methods Fifty-one patients were evaluated (14 female,37male,age range from 7months to 16 years,mean age 8.7 years) with different types of epilepsies ( 20 complex partial seizure,10 tonic-clonic seizure,1 tonic seizure,6 myoclonic epilepsy,2 Lennox-Gastaut syndrome,4 infantile spasms and 2 unspecified epileptic syndromes).The basis for comparison was defined as the seizure frequency in the 3 months prior to the commencement of treatment.Patients received Lev as add-on therapy.The initial dosage was 20 mg/(kg?d),and it was increased 10 mg/(kg?d) every 2 weeks.The maintenance dosage was 30-40 mg/(kg?d).Seizure frequency changes and adverse events were observed.Follow-up was conducted for a period of 6.8 months after treatment.SPSS 14.0 software was used to compare the difference between the seizure frequency before the Lev treatment and that after the Lev treatment.Results Thirteen (25.5%) out of the 51 patients reduced seizure frequency,16 (31.4%) patients had no reoccurrence;While another 9 (17.6%) patients seizure frequencied were reduced,8 patients' remained the same,and 5 patients' condition was got wor-sened.Six cases ceased treatment because of the worsening of the disease and the intolerance of Lev.The difference and after seizure frequency before in Lev treatment is statistically significant(P

0.05).The period when epileptiform abnormalities appear was obviously different(P

0.05).Of essay group 19 children whose PET were normal or slight abnormal,8 children's VEEG had epileptifrom abnormalities only appear in lucid interval,8 children's VEEG had epileptifrom abnormalities appear in nocturnal sleep period,3 children's VEEG had epileptifrom abnormalities appear in lucid interval and nocturnal sleep period.Of essay group,7 children whose PET were serious abnormal,6 children's VEEG had epileptifrom abnormalities appear in lucid interval and nocturnal sleep period.The PET outcome was relate with the time of VEEG epileptic discharge(r=0.461 P

Objective To investigate the effect of apolipoprotein E gene knock-out(ApoE KO) and high-fat diet on morphology and the expression of mortalin in hippocampal CA_3 neurons of mice, and to explore the impact of these factors on memory and Alzheimer's disease.Methods Ten wild-type and 10 ApoE KO mice were fed with common chow as the control group and the KO group respectively while 10 ApoE KO mice were fed with high fat diet.Twelve weeks later, the weight and the lid of these mice were measured.The brain tissues were observed using HE staining, nissl staining, protargol staining,immunohistochemistry staining and image analysis by computer.Results In the ApoE KO group, weight,total cholesterol, triglyceride, low-density lipoprotein cholesterol were higher than those in the control group,and these changes were more significant in ApoE KO high-fat diet group.The nissl was higher in the ApoE KO group (0.301±0.031) and in ApoE KO high-fat diet group (0.261±0.020) than those in the control group (0.341±0.035, F=18.068, P<0.05).The mortalin in the ApoE KO group (0.322±0.060) and in ApoE KO high-fat diet group (0.391±0.041) were higher than the control group (0.256±0.061, F=15.230, P < 0.05).Conclusions ApoE KO and high-fat diet can reduce nissl, and improve the expression of mortalin.This protein may be involved in the pathogenesis of Alzheimer's disease.

AIM: To evaluate the effect of binocular visual function training in pediatric ocular trauma. METHODS: There were 76 patients (76 eyes) that were hospitalized with a primary diagnosis of ocular injury at the Affiliated Hospital of Medical College, Qingdao University between January 2006 and December 2009. Binocular visual function training was given after primary wound repair. Far stereopsis function were checked using AIT-1000 synoptophore fusion, and near stereopsis function was checked using Titmus stereogram.Binocular visual function was compared before and after training. RESULTS: Before binocular visual function training,26 eyes（34%）had no binocular vision, after training there were only 16 eyes（21%） without binocular vision. Before undertaking binocular visual function training with fusion, only 27 eyes (36%) had binocular vision, after the training there were 48 eyes (63%) with binocular vision. Before undertaking binocular visual function training with far stereopsis ,there were 23 eyes (30%) with binocular vision, after the training there were 29 eyes (38%). Before binocular visual function training with near stereopsis, there were 14 eyes (18%) with binocular vision, after the training there were 33 eyes (43%) with binocular vision. There was a significant difference in the number of patients with binocular vision before and after binocular visual function training. CONCLUSION:The training is useful for the reconstruction of binocular visual function in pediatric ocular trauma.

Objective:To explore and analyze the points-selection rules in acupuncture treatment of mammary gland hyperplasia (MGH) by data mining and statistical method. Methods:Clinical literatures about the treatment of MGH with acupuncture published in the recent 16 years were retrieved from Chinese Journal Full-text Database (CJFD) and established into a database by Excel. The SPSS 20 version software and Clementine 12.0 version software were adopted to analyze the frequency and association rules of points-selection in the treatment of MGH with acupuncture. Results:The top 3 points used most frequently in acupuncture treatment of MGH were Danzhong (CV 17), Taichong (LR 3) and Zusanli (ST 36); points from the Stomach Meridian of Foot Yangming and Liver Meridian of Foot Jueyin were most commonly used; the commonly selected points were predominantly distributed in thoracic and abdominal regions and lower limbs; emphasis on the combination use of local and distal points; of the specific points, the five Shu-Transmitting points were mostly used; association analysis showed that the associations among Taichong (LR 3), Danzhong (CV 17) and Zusanli (ST 36) were the most significant. Conclusion: The data mining results substantially accord with the general rules of acupuncture-moxibustion theories in traditional Chinese medicine, able to reflect the points-selection principles and features in acupuncture treatment of MGH and provide evidence for the points selection in the treatment of MGH in acupuncture clinic.

Objective To summarize the clinical characteristics and diagnosis of hemiconvulsion-hemiplegia-epilepsy(HHE) syndrome.Methods The clinical data of 5 children with HHE syndrome were analyzed.Cranial magnetic resonance imaging MRI and /or computerized tomography(CT) and electroencephalogram(EEG) were done in all patients.Results The age of onset was less than 4 years in 4 of 5 patients and initial seizures were associated with fever in 3 cases.The longest duration of convulsive seizures lasted more than 2 hours in all cases,followed by the appearance of hemiplegia involving the side of the body where the convulsions were localized.Subsequent epilepsy developed within 2 years of the hemiplegia in all 5 cases,with 4 cases simple partial seizure and 1 case psychomotor seizures.All cases had mental retardation.Cranial MRI showed left hippocampal sclerosis in 4 patients and CT brain scan showed right cerebral hemiatrophy in 1 case.The EEG showed abnormality in all patients.Epileptiform discharges were found in 4 cases,and the damage hemisphere showed slowing and low voltage of background activity in 1 case.All cases received mainly carbamazepine therapy,and the seizures were satisfactorily controlled or partly controlled.Conclusions HHE syndrome is recognized as hemiplegia-epilepsy syndrome after prolonged hemiconvulsion.The hippocampal sclerosis may be the consequence of repeated seizures,but not the cause.Better understanding of the syndrome,early and adequate treatment of prolonged seizures,especially of febrile convulsion,will reduce the incidence of HHE syndrome.

Objective To assess the long efficacy and safety of Lamotrigine(LTG) monotherapy and add-on therapy different types of epileptic seizures in children.Methods According to the classification of the 1981 and 1989 International Union of Antiepileptic for epileptic seizure,a total of 124 cases with epilepsy were included in the study and divided into non-refractory group with 93 cases and refractory group with 31 cases.LTG treatment only or add-on were used.Original drug dosage was not changed and LTG was added slowly and carefully untill the terrible side effect appeared.The average monthly seizure frequency with baseline in the last 3 months was compared and the side effect was observed.Results Total efficiency was 72.6%,control rate was 51.6%.Total efficiency and control rate of the non-refractory group was 81.0% and 61.3%,which was significantly higher than those of refractory group(48.4%,22.6%).Total efficiency and control rate of the combination group with LTG and valproate sodium(VPA) was 78.4% and 54.5%,which was significantly higher than those of the group of LTG only(61.0%,44.0%).Clinical results was different significantly between the course of the observation period within and over 5 years(P

The influence of separating effect of different chromatographic conditions of mouse gut flora by high performance ion exchange chromatography analysis was studied. The optimum chromatographic conditions for separating gut bacteria were determined. The sample was applied to the chromatography column packed with Toyopearl SuperQ-650c anion resin, equilibrated with 0.02mol/L piperazin-hydrochloric acid buffer (pH 8.0), and elution salt 1mol/L NaCl, eluted with the gradient of 0-50% NaCl/ 80 min, then 50%~75% NaCl/ 25 min at the flow rate 1ml/min, and injecting volume was 1ml.Under these conditions, intestinal flora were separated into several fractions. The establishment of HPLC analysis method will lay a foundation of further research on the components of mouse gut flora and their dynamic changes.

Objective To investigate the inhibitory effect of curcumin on the proliferation of ovarian carcinoma SKOV-3 cells.Methods The model group ( including regular SKOV -3 cells only ) , blank group ( adding amount of nutrient solution) and experimental group were set in experiment.And the experimental group were divided into 7 groups ( the final concentrations of curcumin were 5,10,20,40,80 μmol· L-1 , there are C1 -C5 groups; cisplatin group ( 10 μmol · L-1 ) , 20 μmol · L-1 curcumin+10μmol· L-1 cisplatin group ( combination group) and each were built 6 complex holes.The inhibition effect of curcumin on the pro-liferation of SKOV-3 cells was determined with methythiazolyldiphenyl-tetrazoliumbromide( MTT).The apoptosis rate was determined with PI.The effect of the cell cycle was determined with propidium iodide ( PI ) staining.The the expression of cells in the Bcl -2 protein was deter-mined with ELLISA.Results The curcumin can inhibit the growth of SKOV3, which showed dose -dependent and time -dependent.The apoptosis rate in the model group was 0.15%, the C1 -C5 groups in experimental group were 3.86%, 26.98%, 33.76%, 47.75%, 68.86%,respectively;the cisplatin group was 53.91%, the combinationgroup was 77.96%.The number of the SKOV-3 cells in G0-G1 stage is increasing, in G2-M stage an S stage are in decline with the increasing concentration of curcumin.And the apoptosis rate is increasing ( P<0.05 ).And the curcumin can inhibit the expression of the SKOV -3 Bcl -2 protein, which showed the dose -dependent.Conclusion The curcumin can inhibit the proliferation of SKOV-3, which is co-effected by the induction of apopto-sis and the promotion of the cell cycle arrest.
