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.

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.

ObjectiveTo explore the potentiality of protection by bubble bath hydrotherapy to brain damage of neonatal rats with recurrent seizures.MethodsSixty Sprague-Dawley neonatal rats were randomly divided into control group ( CON),control hydrotherapy group ( HCON ),recurrent-seizure group (RS) and recurrent-seizure hydrotherapy group (HRS).Each group had 15 rats.The volatile agent flurothyl was used to induce 30 min seizure attack.At postnatal day 6 (P6),recurrent seizures were induced once per day for consecutive 6 days in the RS group and HRS group.Rats in the CON and HCON group were placed into the container for same time as their counterpart without exposure to flurothyl.In HCON and HRS groups,Bubble bath hydrotherapy intervention was used after the end of the last seizure for 28 consecutive days.Inspections were made for maturation of physical characteristics,neural behavior.PRG-1 and Bcl-2 protein level in cerebral cortex were detected by western blot method at P50.Results1.Maturation of physical characteristics:body weights of the rats in the RS group were decreased significantly (P＜0.05).Body weights of HRS rats were significantly increased than that of RS rats(P＜0.05 ).There were no significant difference of physiological development phenomenon among the five groups (P ＞0.05 ).2.There was high nerve excitation in hydrotherapy group ( At P26,the scores of OFT respectively were 45.78 ± 18.31 for CON,59.78 ± 25.61 for HCON,27.78 ± 16.83 for RS and 53.15 ± 22.43 for HRS,P ＜ 0.01 ).3.The expression of PRG-1 in cerebral cortex of RS group were significantly higher than that of CON group (1.149 ±0.191 for RS,0.910 ±0.162 for CON,P＜ 0.05 ).The level of Bcl-2 in cerebral cortex of RS group ( 1.149 ±0.191 ) were significantly lower than that of CON group( 1.259 ±0.157) (P＜0.05 ),the level of Bcl-2in cerebral cortex of HRS group( 1.572 ± 0.333 ) were significantly higher than that of RS group(P＜ 0.05 ).ConclusionMaturation of physical characteristics and neurobehavioral were damages following recurrent neonatal seizures,which may be associated with significantly increased level of PRG-1 protein and decreased level of Bcl-2protein in cerebral cortex.The early intervention by Bubble bath hydrotherapy can play a positive role on developmental rehabilitation.

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.

Objective To explore the dynamic expression of a new phospholipid phosphatase, plasticity related gene 1 ( PRG-1 ) in cerebral cortex following recurrent neonatal seizures.Methods A seizure was induced by inhalant flurothyl daily in neonatal Sprague-Dawley rats from postnatal day 6 (P6).Rats were assigned into the recurrent-seizure group (seizures induced in six consecutive days) and the control group.At 3 h,12 h,48 h,14d after the last convulsion,PRG-1 protein level in cerebral cortex was detected by western blot method.Results At 3 h, 12 h,48 h, 14d after the last convulsion in control group, the expression of PRG-1 in cerebral cortex respectively was 1.363 ± 0.742,1.278 ± 0.687 ,0.763 ± 0.374,1.004 ± 0.113, in experimental group , the expression of PRG-1 in cerebral cortex respectively was 1.818 ± 1.093,1.562 ± 0.782,1.024 ± 0.510,1.378 ± 0.279.At 3 h, 12 h,48 h, the expression of PRG-1 in cerebral cortex was not significantly different between the experimental and control group( t = 0.843,0.668,1.011 ,all P ＞ 0.05 ).However, at 14 d, the level of PRG-1 protein in cerebral cortex of experimental group was significantly higher than that of control ( t = 3.041, P ＜ 0.05 ).Conclusion The up-regulated expression of PRG-1 in cerebral cortex may be associated with the recurrent neonatal seizure-induced brain damage.

Objective To explore the repetitive expressions of autophagy marker protein-rnicrotubule-associ-ated protein 1 light chain 3 (LC3) in hippocampus in newborn rats with recurrent seizure and the influence of 3-methyladeine (3-MA) on LC2 expressions. Method Seventy-two 6-day-old SD rats were randomly (random nam-ber) divided into the recurrent neonatal seizure group (RS group, n = 24), the 3-MA-treated seizure group (3-MA group, n = 24) and control group (n = 24). Rats in RS group were subjected to 55 attacks of seizure induced by flurothyl in 9 successive days from the 6th postnatal day (P6). In 3-MA group, 2 μL of 3-MA was injected every day till seizure induced. Western blot analysis was used to determine LC3 protein level in hippocampus at different intervals of 1.5 h,3 h,6 h and 24 h after the last convulsion. The LC3 protein level was analyzed with Dunnett test after ANOVA. Results LC3 protein levels in RS group at the different intervals were significantly higher than those in the control group and in 3-MA group (F =4.70,5.28,8.51 and 5.89, respectively, P <0.05), and there were no significant differences in LC3 protein level between 3-MA group and control group at those intervals (P > 0.05). Conclusions The autophagy/lysosomal pathway is immediately activated after recurrent seizure evidenced by the elevated expressions of LC3 in hippocampus. The 3-MA is involved in the regulation of autophagy/ lysosomal pathway by down-regulating the expressions of LC3.

Objective To evaluate the feasibility,safety and outcome of laparoscopic total mesorectal excision with sphincter preservation in the treatment of low rectal cancer.Methods From April 2004 to April 2007,laparoscopic total mesorectal excision with sphincter preservation for low rectal carcinoma was performed in 25 cases.The intraoperative risk.recovery,short-term and oncological outcomes of these patients were compared with 25 cases of conventional Dixon's operation.The controls,matched for age,sex,mass margin distance from the anus,Dukes stage,were selected from conventional Dixon's operations performed at the same period as laparoscopic group.T test and Chi-square test were used.Results Laparoscopic procedure was successful in 24 cases while one was converted to Bacon operation.The mean operation time(197±36)min in laparoscopic group was significantly longer than those(172±51)min in open group(t=2.12,P=0.04).The mean operative blood loss was(157±105)ml in laparoscopic group and(304±237)ml in open group(t=-2.95,P=0.01).No significant differences were detected between two groups in specimen length and number of lymph nodes excised.The bowel function was restored earlier in laparoseopic group than that in open group.The overall morbidity rates were 16%and 28%,and the local recurrence rates were 8%and 4%in the two groups respectively.Conclusion Laparoscopic total mesorectal excision is a feasible,safe,minimally invasive technique for rectal cancer.which provides better short-term outcomes and similar oncological outcomes compared with the traditional open procedure.
