Objective To explore the long-term effects of bubble baths on seizure-induced neurobehavior deficits and the expression of apoptotic/autophagic marker B cell lymphoma/leukemia-2 ( Bcl-2 ),Beclin-1,and plasticity-related gene-1 ( PRG-1 ) in newborn rats. MethodsSixty rats aged 6 days were randomly divided into 4 groups:a control group (CON),a control hydrotherapy group (HCON),a recurrent-seizure group (RS) and a recurrent-seizure hydrotherapy group (HRS),with 15 in each group.Flurothyl was used to induce 30 min of seizures daily for 6 consecutive days in the RS and HRS groups.Rats in the CON and HCON groups were placed in the same container for equal duration without exposure to flurothyl.Rats in the HCON and HRS groups were given bubble baths for 28 consecutive days after the end of the last seizure.Neurobehavioral damage was observed using open field behavior at postnatal day 26 (P26) and Morris water maze performance at postnatal day 43 to 49 (P43-P49) and a single-blind method.PRG-1,Bcl-2 and Beclin-1 protein levels in the hippocampus were detected by Western blotting at postnatal day 50 (P50). Results①The average open field test scores of the RS rats decreased significantly compared with those of the CON and HRS rats at P26.②In the Morris water maze test the average latencies of all rats decreased gradually from the 1st to 5th days (d1 to d5) after establishment of seizure model.The average escape latency was significantly longer for rats of the RS group than for CON group rats at the 4th and 5th days ( d4 and d5 ) after establishment of seizure model.The escape latency was significantly shorter for rats of the HRS group than for RS group rats at d4.③The level of Bcl-2 protein in the hippocampus was much lower in the RS group than in the HRS and control groups.In addition,the expression of PRG-1 in the RS group was significantly higher than in the CON group. ConclusionsRecurrent prolonged seizures cause long-term neurobehavior deficits,which might be associated with the down-regulated expression of Bcl-2 and up-regulated expression of PRG-1 in the hippocampus.Bubble baths can improve the neurobehavioral sequelae from seizures,perhaps through up-regulation of hippocampal Bcl-2 expression.

Objective To analyze the expression of prolactin protein and ZnT1 mRNA in rat brain in the wake of heat stress and febrile convulsion(FC).Method Thirty-six weanling Spragne-Dawley rats were randomly divided into control group(n=8) and other 28 rats were used to induce heat stroke by warm water but three of them failed to produc expected heat stress.Consequently,there were 35 rats eligible to be models of heat stroke,and of them,10 rats showed heat stress(HS group,n=10) and 15 rats had 5-grade febrile convulsion (FC group,n = 15).The inmmunohistocbemistry and in situ hybridization method were used in this study.The IR) neurons were found in the rats of control group.The deep immune staining was found in the PIR,Era and RS regions of cerebral cortex and light immune staining was found in the PRH,PAR and FR regions of cerebral cortex in HS group.In addition,the PRL-IR positive neurons were found around the midline strip of thalamus without characteristic subnucleus-specific distribution.However,abundant induction of PRL-IR positive neurons with diffuse distribution were found in cerebral cortex,hippoeampus,amygdala,thalamus and hypotha]amns of rats in FC and FC rats showed more PRD-IR positive neurons in cerebral cortex than those in rats of control group (P

Objective To compare the effects of hypothermic arrest circulation ( HAC) with moderate or deep hypothermic antegrade selective cerebral perfusion ( ASCP) technique in patients with DeBake type Ⅰ aortic dissection or aortic arch aneurysm undergoing total aortic arch replacement. Methods Between Feb. 2007 and Aug. 2009, 60 patients who underwent aortic arch replacement using HAC + SCP technique. Patients were divided into two groups according to the lowest nasopharyngeal temperature: moderate hypothermia (18 - 20℃) (group MH, n = 28), and deep hypothermia (23 -25 ℃) (group DH,n=32). The clinical and neurological outcomes were observed. Results The overall in-hospital mortality was 3. 33% (2/60) ; In-hospital mortality was 3. 6% in the MH group, while3.1% in the DH group. There were no significant differences regarding to preoperative the patients' character parameters in both groups. At the beginning of ASCP, the nasopharyngeal and rectal temperatures were significantly higher in group MH[MH group (23.8 ± 1. 9 ) ℃ ( 26. 6 ± 2. 4 ) ℃ vs. DH group group (29.4 ±9.3) min vs. DH group(32.9 ± 13.4) min]. The rewarming time and CPB time were significantly shorter in MH group[(65.0±13.9) min vs. (90.3 ±27.2) min; (142.8 ±34.2) min vs. (194.1 ±42.0) min, P <0. 05]. Temporary neurologic deficits occurred in four patients (6. 67% ) without significant differences between two groups ( MH group 7.14% vs. DH group 6. 25% ). No patient suffered from permanent neurologic dysfunction. There were no significant differences between two groups in other parameters including intubation time, kidney insufficiency, the stay times in ICU and hospital. Conclusion Our results demonstrate that moderate HCA + ASCP technique is a safe strategy for the treatment of patients who require conventional total arch replacement with individual arch-vessel reconstruction. Shorter CPB time in patients with moderate HCA + ASCP did not increase any other postoperative adverse effects.

ObjectiveTo explore the intervention effect and the underlying molecular mechanism of 3-Methyladenine on behavioral damage of neonatal rat with prolonged seizures. MethodsForty-five 6-dayold SD rats were randomly ( random number) divided into the recurrent prolonged neonatal seizure group ( RS group), the 3-MA-treated seizure group and control group. The volatile agent flurothyl was used to induce 30 min seizure attack. At postnatal day 6 (P6), recurrent seizures were induced once daily for successive 6 days in both RS group and 3-MA group. In 3-MA group, 3-MA (2 μL) was injected daily before seizures induced.Neural-behavior changes were observed with double-blind method including swimming development, open field test and Morris water maze analysis. Bcl-2 and Beclinl protein levels in hippocampus were detected by western blot method at P50. ResultsThe total scores of swimming behavior in RS rats were decreased significantly compared with those of control and 3-MA rats ( control: 7. 44 ±1. 13, RS: 5.06±1.63, 3-MA: 7.33 ±1.08, F=16.19, P＜0. 01) . The start-latency time of open filed behavior in RS rats ( 13. 33 ±6. 69) were increased significantly compared with that of control (7. 11 ±2. 37) and 3-MA rats (9. 91 ±4. 23) (F=4. 39, P＜0. 05). The escape latency was significantly longer in rats of RS group than that of control and 3-MA rats on the 4th and 5th days (P ＜ 0.05). The level of Bcl-2 in hippocampus of RS group (0. 587 +0. 139) were significantly lower than that of control (0. 782 +0. 083) and 3-MA groups (0. 799 + 0. 163) (F =4. 7 1, P ＜ 0. 05 ). There were no significant differences in the level of Beclin1 protein in hippocampus among the three groups ( F =0. 27, P ＞ 0. 05 ).Conclusions Pretreatment with autophagy inhibitor 3-MA in acute phase of neonatal seizures could significantly improve neurobehavioral capacity, which might be associated with the increased in the level of Bcl-2 protein in hippocampus.
