癫(癎)是儿童常见的神经系统疾病,近年来有关难治性癫(癎)发病机制的研究取得一些突破性进展.文章就难治性癫(癎)发病机制的研究现状进行综述,主要包括4个方面的内容,其中多药转运体表达增多可能导致进入脑组织的药物浓度降低是产生耐药的主要因素,文章重点阐述多药耐药基因和难治性癫(癎)的关系,并对难治性癫(癎)的进一步研究方向和临床应用前景提出新的思路.“,”Epilepsy is a common neurological disorder of children. Research in recent years on the mechanism of refractable epilepsy has made some breakthrough. Four concepts have been put forward to explain the development of pharmacoresistance. The transporter hypothesis have become the focus, which contends that the expression or function of multidrug transporters in the brain is augmented, leading to impaired access of antiepileptic drugs to central nervous system targets. An emerging understanding of these underlying molecular and cellular mechanisms is likely to provide important impetus for the development of new pharmacological treatment strategies and clinical test facility.
