Objective To investigate the features of the memory function disturbance in patients of generalized seizures and the correlation between the memory function and proton magnetic resonance spectroscopy(1H-MRS).Methods The clinical memory scale of 45 general seizures and 20 normal age and sex-matched controls wss measured and a1 H-MRs was performed in the bilateral hippoeampal.The levels of NAA.Cho.Cr and the ratios of NAA/Cr+Cho were compared between these two groups.Meanwhile,tHe correlation coefficients was calculated and the results of clinical memory scale scoreB and the level of NAA,Cho.Cr and the ratios of NAA/Cr+Cho in groups were compared.Results As compared with the controls.the scores of pointing memory(17.19±5.86),associational learning(20.00±6.77),image free memory(18.44±6.62),association memory of portrait(13.19±6.62)and memory quotient (MQ,79.07±20.20)excepts insignificant figure recognition wcrc significandy decreased in patients of seizures(t=4.794-10.224,all P<0.01);The scores of scale and MQ of both the group of patients who wok antiepileptic drugs(AEDs)and the group of patients whose frequency exceeded 3 per month were significantly lower than the group who didn't take AEDs and the group whose frequency was lower than 3 per month(t=3.267-6.537,all P<0.01).The volumes of hippocampal formations(2.45 ±0.25 on left and 2.56 ±0.31 on right),the level of NAA(12.93 ±1.73 on left and 11.88 ±1.69 on right),Cho(15.02 ±0.86 on left and 14.94 ±0.96 on right),Cr(11.86 ±0.71 on left and 10.71 ±0.42 on right)and the ratios of NAA/Cr+Cho(0.48 ±0.08 on left and 0.39 ±0.07 on riht)in the group of pailents of generalized seizures were significantly difference than those in the controls(t=4.103-5.768,all P<0.01).Patients with seizures showed significant correlation between tlle scores of all items.MQ in clinical memory scale and NAA,NAA/Cr+Cho ratio(r=0.489-0.727,all P<0.01),and inverse correlation between the scores and MQ and Cho of in the bilateral hippocampal(r=-0.604-0.484,all P<0.01).However,there was no correlation between the scores and MQ and Cr of in the bilateral hippocampal.Condusions The patients of the general seizures do have the problem of the disturbance of short-term memory including acoustic memory and some visual memory.Both the high frequency of seizure and AEDs could affect the short-term memory function.The correlation between the scores of all the items and MQ in clinical memory scale proved that lack of nerve cell and hyperplasia of gliocyte was one of the reasons of the short-term memory disorder in epileptic.

Objective To assess health-related quality of life and the mood disorder in adults with epilepsy,and to evaluate factors contributing to the quality of life.Methods Quality of life was measured by the Quality of Life in Epilepsy Inventory(QOLIE-31)and the World Health Organization Quality of Life Assessment-Bref(WHOQOL-BREF).Psychotic conditions were evaluated by Self-rating Depressive Scale (SDS)and Self-rating Anxious Seale(SAS).The multivariate analysis was used to assess the determinant factors.Results The study included 141 epilepsy patients in the teat group and 59 sex,age,and education matched normal controls. WHOQOL-BREF scores in the physical and psychological aspects were significantly lower in epilepsy patients(12.7 ±1.8 and 12.4±1.9,respectively)than those in the normal controls(15.1 ±2.3 and 13.9 ±1.9,respectively,t value were 11.75 and 8.625.both P<0.05).The survey reported that 57.4 % of the epilepsy patients suffered with depression.and 39.7 % anxiety.The patients with both anxiety and depression scored lower in all aspects in QOLIE survey except medical effect.Multivariate analysis showed that factors that effect the overall quality of life in order were anxiety.depression and disease duration.Conclusion Our results support that complications of anxiety and depression and long disease duration are key factors affecting the quality of life in epilepsy patients.

Objective To search for the methods of inducing the high stability rat middle cerebral artery occlusion (MCAO) model and to noninvasively assess the method of model effect. Methods Six kinds of filaments with different diameters were used to induce rat MCAO models and their success rate, incidence of subarachnoid hemorrhage, and infarct volume were compared. The model scores were performed to assess the model effect after the operation and at 24 hours after reperfusion. Results Higher model success rate and lower incidence of subarachnoid hemorrhage were achieved when the 0. 28 mm in diameter and 0.32-0.34 mm in tip diameter filaments were used. 1he sensibility and specificity were higher when the model scores were performed at 24 hours after reperfusion. Conclusions Using the filaments of 0.28 mm in diameter and 0. 32-0. 34 mm in tip diameter for intraluminal thread could improved the stability of the models. The model scores at 24 hours after reperfusion could noninvasively assess the model effect.
