Objective To analyze efficacy and its influencing factors of phenobarbital treatment for epilepsy management in rural China.Methods Total 3 315 patients with convulsive epilepsy from rural areas of 24 counties were enrolled in this joint epilepsy management program.All patients received phenobarbital monotherapy for 1 year during November 2011 to November 2013.The efficacy and potential influencing factors including sex,age,duration of epilepsy,number of seizures in the 12 months before management(≥2),previous treatment,daily dose of phenobarbital,taking other antiepileptic drugs and compliance of patients were studied with multivariate analysis.Results Among 3 315 patients,38.9％ were seizure-free during the entire management period.The rates of seizure-free in 15 to 39 y age group (35.2％,495/1 405)and in patients receiving irregular treatment previously (34.6％,625/1 808)were lower.The rates of seizure-free were higher in patients taking phenobarbital 60-90 mg everyday (49.4％,988/2 000) and those with good compliance(42.3％,1 160/2 744).Patients taking other antiepileptic drugs in 12 months had lower seizure-free rate (31.0％,45/145).Univariate analysis showed that gender of patients was not related to seizure-free rate (P ＞ 0.1).Multivariate analysis showed that the longer duration of epilepsy(OR =0.015,95％ CI:1.008-1.021,P ＜ 0.001),more seizures in the 12 months (OR =0.005,95％ CI:1.002-1.007,P =0.002) and the irregular treatment before management were the risk factors for low seizure-free rate (P ＜ 0.05).Patients received formal treatment or untreated had a lower risk of seizure compare with the irregular treatment (OR =0.737,95％ CI:0.611-0.889,P =0.001;OR =0.566,95％ CI:0.469-0.683,P ＜0.001).Patients with good compliance and with a daily dose of 60-89 mg phenobarbital(OR =0.107,95％ CI:0.013-0.905,P =0.040) were associated with high seizurefree rate;in contrast the poor compliance was a risk factor for not being seizure-free(OR =2.038,95％ CI:1.634-2.541,P ＜ 0.001).Conclusion Regular medication of phenobarbital with good compliance is effective for convulsive epilepsy management in rural China.

Objective To investigate the therapeutic effect of intracerebral transplantation of mesenchymal stem cells(MSCs) derived from human umbilical cord blood(UCB) on hypoxic-ischemic brain damage(HIBD) in neonatal rat.Methods Twenty samples of human UCB were collected from healthy full-term newborns.MSCs were isolated from human UCB by density gradient centrifugation and purified by adhere cell selection method.For transplantation,P3 human UCB-derived MSCs were labeled by the 5-bromo-2-deoxyuridine (BrdU).Thirty SD rats of 7 d were built for neonatal HIBD model.One rat died and others were divided into transplant group(n=18) and control group(n=11).At the third day after building models,human UCB-derived MSCs were injected into left cortex in transplant group,while PBS of the same volume was injected into the same site in control group at the same time.The seventh day after transplantation,6 rats of transplant group were sacrificed to prepare brain tissue sections.The survival,migration and differentiation of the transplanted cells were investigated by brain tissue immunohistochemical analysis,and nervous function of 2 groups were evaluated by modified neurological severity score(mNSS) on the first,7th,14th,21th and 28th day after transplantation.Results MSCs were isolated from 5 of 20 human UCB samples.Immunocytochemical analysis of brain tissue showed that the transplanted human UCB-derived MSCs could survive and migrate around by the center of transplant site.There were (12.67?2.73)% of MSCs differentiated into astrocyte-like cells.mNSS showed that the score of transplant group was lower than that of control group on the first,7th,14th,21th and 28th day,and the differences of score points between 2 groups on the 14th,21th and 28thday were statistically significant(Pa

AIM:To observe related biological parameters of 3 minutes dark-room provocative test in patients with laser peripheral iridectomy(LPI) in the fellow eyes of acute primary angle-closure (APAC) by ultrasound biomicroscopy (UBM).To explore the risk factors in primary angle closure suspect(PACS) patients with progressive angle closure after LPI.METHODS: Seventy-eight eyes of APAC patients without peripheral anterior synechia were selected.Each eye underwent 3 minutes dark-room provocative test after LPI.Anterior segment parameters, including anterior chamber depth (ACD), anterior chamber angle open distance500 (AOD500), peripheral iris thickness (PIT), iris convex (IC), the position of iris insertion and trabecular-ciliary process distance (TCPD), and the number of positional angle closure(NPAC) were observed and analyzed by statistic methods.RESULTS:Patients with APAC were examined by UBM after LPI and 26 eyes(33%) occurs at least one positional angle closure,19 eyes(24%)were positive in 3 minutes dark-room provocative test among them.It occurs a positive relationship between the elevation intraocular pressure and the number of positional angle closure in dark-room provocative test(r=0.84, P<0.01).AOD500, IT and IC were significantly changed from normal light to darkroom between positional angle closure positive group and positional angle closure negative group(all P<0.01).In single factor analysis, AOD500(P=0.003), IT(P=0.012), IC(P=0.043), TPCD(P=0.015), the position of iris insertion(P=0.024) were correlative factors of positive results.In multiple-factor analysis, only IT(P=0.011), TPCD(P=0.009), iris root attachment points(P=0.02) were independent risk factors of positive results.CONCLUSION:A certain proportion of patients with PACS after LPI appeared positional angle closure in a dark room.Peripheral iris hypertrophy, anterior displacement of the ciliary body and iris root attachment points are vital risk factors.Long-term follow-up study and intervention treatment are required in these patients after LPI.

Objective To study interleukin-1 receptor(IL-1R) and connexin(Cx36) gene expression following Mg 2+-free-induced seizures in cultured developing neuron. Methods Rat embryo cortical neurons cultured for 6 and 17 days were exposed to Mg 2+-free media to induce seizure. At different time after Mg 2+-free treatment, real-time RT-PCR was used to detect IL-1R and Cx36 mRNA expression. Results 1. IL-1R mRNA expression transiently decreased after Mg 2+-free treatment in neurons cultured for 6 and 17 days in vitro. Then the levels of IL-1R mRNA expression recovered in neurons cultured for 6 days, but IL-1R mRNA expression were increased in neurons cultured for 17 days compared with control group and the peak was at 24 hours. 2. In neurons cultured for 6 days in vitro, Cx36 mRNA expression increased after Mg 2+-free treatment compared with control group, the peak was at 24 hours. But in neurons cultured for 17 days in vitro, Cx36 mRNA expression decreased at 6 hours after Mg 2+-free treatment compared with control group, the peak was at 24 hours. Conclusions IL-1R mRNA and Cx36 mRNA expression following Mg 2+-free-induced seizures are different between the neurons cultured for 6 and 17 days in vitro. This is possibly related to the different neuron injury between 6 and 17 days in vitro following seizures.
