Abstract： Objective To explore the dynamic expressions of autophagia and apoptosis associated protein Beclin-1, Cathepsin B and Bcl-2 in hippocampus and the intervention efficacy of cathepsin-B inhibitor (CBI) after recurrent neonatal seizure. Method Ninty 6-day-old SD rats were randomly (random number) divided into the recurrent neonatal seizure group (RS group, n = 30), CBI-treated seizure group (CBI group, n = 30) and the control group (n = 30). Rats in RS group were subjected to 55 attacks of seizure induced by using flurothyl during the consecutive 9 days beginning on the 6 th postnatal day (P6). In CBI group, CBI (2 μL, 0.5 μg/μL) was administered every day before seizures induced. Western blot was employed to determine the protein level at different intervals (1.5 h,3 h,6 h,24 h) after the last convulsion.Results There were higher expressions of Beclin-1 and Cathepsin B, and lower expressions of Bcl-2 expression in RS group(1. 5 h,3 h,6 h and 24 h) than those at the same time in control group (P ＜ 0.05). Beclin1 and Cathepsin B expressions were lower while Bcl-2 expressions were higher in CBI group at the intervals of 1.5 h,3 h,6 h and 24 h compared with those in RS group (P ＜ 0. 05). Conciusions Autophagic and apoptotic pathways were activated immediately after recurrent neonatal seizures as indicated by expression changes of Beclin-1, Cathepsin B and Bcl-2 in hippocampus, which suggests a synergistic effect of the two pathways in the pathophysiology of the long-term brain damage of neonateε resulted from the adverse effects of recurrent neonatal seizures.
