Objective To investigate the time course of nuclear factor-κB(NF-κB) and the effects of pyrrolidine dithiocarbamate (PDTC) on the expressions of NF-κB,tumor necrosis factor-α (TNF-α) and interleukin1β(IL-1β) in hippocampus after seizures.Methods Epilepsy were induced by [PTZ] through Intraperitoneal injection.Western blotting was used to detect NF-κB p65 expression in nucleus at various experiment groups in different time points( 14d,21 d,28d,35d).Moreover,mRNA and protein expressions of TNF-α and IL-1β in different experiment groups in different time points by Real-time quantitative PCR and ELISA analysis.Results The expression of NF-κB p65 began to increase in the nuclear fraction in 14d,kept rising in 28d and returned to 14d level in 35d after epilepsy seizures,At 14d,21d,28d and 35d,the expressions of NF-κB in PDTC groups ( (0.54 ±0.07),(0.65 ± 0.08 ),(0.78 ± 0.10),(0.78 ± 0.10) ) was significantly lower than those in PTZ groups ((1.20 ±0.11),(1.42 ±0.14),(1.88 ±0.16),(1.25 ±0.10)) (P＜0.01).After epilepsy seizures,the expression of TNF-α 、IL-1β mRNA was increased in PTZ groups( ( 1.34 ±0.13,0.81 ± O.17 ),( 1.64 ±0.17,1.56±0.20),(2.03 ±0.16,1.65 ±0.18),(1.40 ±0.10,1.30 ±0.13) ) than those in NS groups(P＜0.01 ) ;and compared with PTZ groups PDTC significantly decrease the mRNA expressions of TNF-α and IL-1 β in PDTC groups( (0.96 ±0.1,0.57 ±0.07),(1.36 ±0.15,1.09 ±0.18),(1.47 ±0.14,1.25 ±0.16),(1.12 ±0.12,O.85 ± 0.12) ) (P ＜ 0.05 ).The expressions of TN F-α,IL-1β protein were similar in hippocampal by ELISA.Conclusion Seizures induces NF-κB nucleus translocation and promotes the expressions of TNF-ot and IL-1 β in hippocampus and pyrrolidine dithiocarbamate suppresses NF-κB associated inflammatory pathway in epileptic rat hippocampus.

Objective: To explore the risk factors in patients with chronic heart failure (CHF) combining atrial ifbrillation (AF) and to identify the predictive factors for AF recurrence after cardio version. Methods: A total of 246 CHF patients treated in our hospital were divided into 2 groups: CHF+AF (AF) group,n=71 and CHF without AF (Non-AF) group,n=175. The baseline information was recorded. The risk factors for AF occurrence were screened by Logistic regression analysis. There were 66 AF patients with successful cardio verse and they were followed-up for 18 months, the predictors for AF recurrence were studied by Cox regression analysis. Results: The baseline information showed that age, CHF duration, left atria diameter (LAD), the levels of BNP, uric acid and serum creatinine in AF group were all higher than those in Non-AF group, allP<0.05. Logistic regression analysis presented that age (RR=1.89, 95% CI 1.08-3.31,P<0.05), CHF duration (RR=1.35, 95% CI 1.05-1.74,P<0.05), BNP level (RR=1.82, 95% CI 1.30-2.53,P<0.01), LAD (RR=1.51, 95% CI 1.09-2.08,P<0.05) were the risk factors for AF occurrence. Cox regression analysis indicated that BNP level (RR=1.30, 95% CI 1.09-1.54,P<0.01) and LAD (RR=1.74, 95% CI 1.30-2.34, P<0.01) were the predictors for AF recurrence. Conclusion: The elder age, longer CHF duration, increased BNP level and LAD were the risk factors for AF occurrence in CHF patients. The increased BNP level and LAD were the objective predictors for AF recurrence after cardio version.
