  • 癫痫网络的定义:立体脑电图和信号分析的贡献

    致痫网络定义为癫痫放电产生和传播过程中累及的脑区。基于颅内电极电生理数据的分析,文章综述介绍了致痫网络的历史、方法和概念。在癫痫术前评估中,确定产生癫痫发作的脑区(如致痫区)是最重要的目标。较药物难治性局灶性癫痫传统的、局限性的视觉分析方法而言,致痫网络作为一个模型已逐渐得到公认。该模型能更好地描述发作动态演变的复杂性、更真实地描述大脑致痫性的异常分布。致痫网络概念在历史上与立体脑电图(SEEG)方法学的发展及随后脑电信号定量分析相关。SEEG 有明确的发作期、发作前及发作间期放电模式,可以用信号分析方法对上述模式进行分析,如高频振荡定量分析或分析功能连接的改变。我们可以在皮层和皮层下脑区癫痫发生和传播的过程中,依据 SEEG 数据分析得到大脑连接的显著变化,这些变化与不同的发作症状学模式相关。发作间期特征就是致痫网络产生异常电活动(发作间期棘波)及功能连接的改变。致痫网络大尺度建模新方法的引入为更好地预测手术预后提供了新方法。就明确致痫性脑区的分布而言,致痫网络的概念是一个关键的要素,这对癫痫手术尤为重要。

  • Clinical study of perampanel and levetiracetam monotherapy in the treatment of focal epilepsy and its effect on miR-106b and autophagy related protein

    ObjectiveTo observe and compare the epileptic seizures, EEG changes and adverse reactions of perampanel and levetiracetam monotherapy in children with focal epilepsy. To explore the efficacy and safety of Perampanel monotherapy in the treatment of focal epilepsy and its relationship with miR-106b and autophagy related protein pathwaynide monotherapy in the treatment of focal epilepsy. Methods A total of 74 children with focal epilepsy in Xuzhou Children’s Hospital from March 2021 to December 2023 were selected as the research objects, all of whom were randomly divided into perampanel group and levetiracetam group. They were treated with perampanel and levetiracetam respectively. The clinical seizures, epileptiform discharges of EEG and adverse reactions were recorded and compared between the two groups. 2 mL of fasting peripheral blood were collected from the two groups of children in the morning, and the RNA of lymphocytes in the blood sample was extracted, the expression of miR-106b in peripheral blood lymphocytes of children was detected by qRT-PCR amplification, the levels of autophagy related protein Beclin-1, LC3-Ⅱ and p62 in the peripheral blood of children were detected by enzyme-linked immunosorbent assay. Results There was no significant difference in age, gender, BMI, course of disease, seizure frequency, epileptiform discharge index of EEG between the two groups (P>0.05). Seizure control: After treatment, the total effective rate and retention rate were 81.1% (30/37) and 78.4% (29/37) in the perampanel group and 59.5% (22/37) and 56.8% (21/37) in the levetiracetam group, respectively. The total effective rate in the perampanel group was higher than that in the levetiracetam group, with statistical difference (P<0.05). The retention rate in the perampanel group at 12 months was higher than that in the levetiracetam group, with statistical difference (P<0.05). EEG improvement: after treatment, the control improvement rate and total improvement rate of EEG in perampanel group were 32.4% (12/37) and 78.4% (29/37), and the control improvement rate and total improvement rate of EEG in levetiracetam group were 16.2% (6/37) and 56.8% (21/37), respectively, with statistical difference between the two groups (P<0.05). EEG in perampanel group was significantly improved. Adverse reactions: the incidence of adverse reactions in the perampanel group and Levetiracetam group was 10.8% (4/37) vs 24.3% (9/37). There was no statistical difference between the two groups (P>0.05). MiR-106b and autophagy related proteins: the expression of miR-106b, Beclin-1, LC3-Ⅱ in perampanel group was significantly decreased compared with that before treatment, with statistical differences (P<0.05). The expression of p62 was also increased compared with that before treatment, with obvious differences (P<0.05). There was no significant difference in the expression of miR-106b, Beclin-1, LC3-Ⅱ, p62 between levetiracetam group and perampanel group (P>0.05). Conclusion The clinical efficacy of perampanel as the first choice for the treatment of children with focal epilepsy is better than levetiracetam, which can effectively control seizures, improve the EEG of children, and has a low incidence of drug-related adverse events. Perampanel may exert antiepileptic effect by affecting miR-106b and autophagy related proteins.

  • Research progress on the mechanism of action of perampanel and its clinical efficacy for self-limited epilepsy with centrotemporal spikes

    Anti-seizure medications (ASMs) are the most important and basic treatment for epilepsy, and are also the first choice for epilepsy treatment, but about one-third of patients have drug resistance. Perampanel (PER), as a novel third generation ASMs, inhibits the α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptor (AMPAR) through non-competitive inhibition. AMPA plays an anti-seizure role. Since its approval in China in 2021, it has been mainly used in the treatment of focal epilepsy (with or without general seizure) as a single drug or addition, and has good safety, effectiveness and tolerability. Self-limited epilepsy with centrotemporal spikes (SeLECTS) is a common childhood focal epilepsy syndrome, accounting for 15% ~ 25% of various childhood epilepsies, PER has important advantages in clinical studies and has shown certain curative effect. At the same time, the overall effect of PER on cognition was neutral, with no systemic cognitive deterioration or improvement. In view of the relatively short application time of PER, which is still a new drug, this article will review the mechanism of action, dose, add-on (single drug) treatment, adverse events and, in order to provide clinicians with more drug choices and facilitate the individualized diagnosis and treatment of epilepsy.

  • 伴中央颞区棘波自限性癫痫患儿的认知功能:一项系统评价和荟萃分析

    现在良性癫痫伴中央颞区棘波[(Benign epilepsy with centrotemporal spikes,BECTS),或近期多被称为 ECTS]与一系列认知和行为障碍相关的观点已经被广泛接受。尽管对 ECTS 的认知功能已经有了进一步的了解,目前仍没有在综合认知框架之下进行的量化分析研究。该系统评价和荟萃分析是在 PRISMA 指南的指导之下进行的。42 项对照研究满足纳入条件,共计包含 1 237 例 ECTS 患儿和 1 137 名健康对照儿童。对 8 个认知因素以及 Cattell-Horn-Carroll(CHC)智力模型进行单变量,随机效应荟萃分析。总体来说,ECTS 患儿在神经心理学测试中所有认知方面与健康对照相比均明显偏低。观测效应从 0.42~0.81 集中标准差单位不等,其中长期存储和获取为最大效应而视觉信息处理为最小效应。目前荟萃分析的结果首次提供了 ECTS 患儿展现一系列普遍性的认知障碍的证据,因此对目前认为 ECTS 是一个良性疾病或者认为仅存在局限性、特定认知功能损害的观点提出了挑战。
