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.

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 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 explore the long-term effects of physical exercises on penicillin induced recurrent convulsion with learning and memory deficits in developing rata and its mechanism.Method:Fifty-six male SD rats(postnatal days [PD]21)were randomly divided into four groups:control group (CONT1),control plus exercises group(CONT2),convulsion group(EXP1)and convulsion plus exercises group(EXP2) ,rwenty rats were assigned for two control groups,each n=10;the surplus 36 rats were kindled by penicilln onceper d,consecutive 6d for creating convulsion models.Control rats were injected equal amount of normal sodium(NS) into abdominal cavity at the same time.The 20 qualified models of convulsion rats were randomly divided into two EXP groups.On PD39-PD43 and PD61-PD64,subjects of the four groups were tested with Morris water maze,and from PD49 to PD54.the rats of CONT2 and EXP2 were given exercises of running wheels,twice a d for consecutive 6d.The expression of glutamicacid receptor 2(GluR2)in hippocampus was detected. Result:①In the first Morris water maze test,there were significant differences of latency among four groups(F=5.56,P<0.01),and the latency of two EXP groups were significantly longer than two CONT groups(P<0.05);In the probe trial,the frequency of two EXP groups passing through target area were significantly less than that of two CONT groups.②In the second water maze test.there were significant effects of exercises on the latency of EXF2 group comparing to EXP1 group (P<0.05);the frequency of two EXP groups passing through target area were still significantly less than that of two CONT groups after exercises training(P<0.05),and there Was no significant difference between EXP1 and EXP2 groups.③In the immanohistochemical staining of GluR2,the gray values in hipocampus of two convulsion groups were significantly lower than that of two control groups(P<0.05). Conclusion:Penicillin induced recurrent convulsion could cause long-term effects on learning and memory in rats,which may be associated with down-regulated GluR2 expression in hippocampus.Physical exercises could improve learning capacity,of convulsion rats but not memory capacity.

Objective To explore the intervention effect of cathepsin B inhibitor (CBI) and its signaling pathways after flurothyl inducing brain injury in rats with recurrent seizures. Methods 6-day-old (P6) SD rats were randomly divided into: recurrent neonatal seizure group ( RS group, n = 30), CBI-treated seizure group ( CBI group, n=30) and the control group( CONT group). Rats in RS group were subjected to 5 seizures with flurothyl during the first 14 days of life. In CBI group,CBI was injected each day before seizures were induced. Then examined development indexes such as the physical growth, neural reflex, neural behavior and cognitive emotional competence. Western blot was employed to determine Cathepsin B expression at different time points ( 1.5h,3h,6h,24h and P35) after the last convulsion. Results The weights of rats in RS group( (27.28 ± 1.6) kg) were lighter than CONT group( ( 33.45 ± 1.57 ) kg). They had significant difference (P＜ 0.01 ) at the age of p14. The time of cliff avoidance in RS group( (2. 10 ± 1.45 ) s) was longer than CBI group( ( 1.05 ± 0. 32) s). It showed a statistically significant (P ＜ 0.05 ) in p12. In the open-field behavior test: the activities of RS group (20.00 ± 13.08 )were markedly reduced than CONT group ( 57.83 ± 33.22 ) in the horizontal movements, the RS group ( 2.50 ±2.43 ) were significantly decreased than the CONT group and CB1 group( ( 22.17 ± 10.74), (9.33 ± 5.39 ) ) in the vertical motions (P ＜ 0. 05 ). Cathepsin-B expression in RS group( 1.5h, 3h,6h and 24h )was significantly higher than that at the same time in CONT group(P＜ 0. 05 ). Cathepsin-B expression of CBI group was significantly decreased compared with that in RS group (P＜ 0. 05 ) at the time point (1.5h ,3h,6h and 24h). There were no significant differences among three groups at P35(P＞0.05 ). Conclusions CBI can improve brain injury and regulate the expression of abnormal molecules.

Objective To explose the experimental basis of microchemoembolism therapy on colon carcinoma. Methods 12 dogs were randomly divided into two groups. Performing inferior mesenteric arterial and portal vein catheterization. Simple contrast medium and the contrast medium mixed with CH 44 (?10～20?m) for the angiograms were analysed under DSA. The concentration of 5 Fu in the protal vein were measured with Liquid Chromatography and in recorded diagramatic curve. The half life times of 5 Fu after simple arterial infusion chemotherapy or after microchemoembolism therapy were calculated and analyzed with t test(in Microsoft Excel 97). 5 minutes and 3 hours after the microchemoembolism therapy, embolized colonic segment were taken and observed under optic and transmission electron microscopy. Two weeks later, autopsy was performed. Results The opacificotion time of simple contrast medium after injection was 6.25?1.50 seconds. The arteries looked smooth. The vessels oppeared to show spasm and tortuous after perfusion of the same amount of contrast medium mixed with CH 44 particles associated with narrowing of te bronches the opacification time was 930?192 seconds, which was conspicuously dramatically different from the simple contrast medium. In the simple contrast medium group, the initial concentration of 5 Fu in the portal vein was rather high, then it attenuated rapidly. The mean half life time was 12.36?5.25 min. In the microchemoembolism therapy group, the initial concentration of 5 Fu was relatively lower. After injection, it increased for a little while and then decreased slowly. The mean half life time was 47.37?14.02 min, which was conspicuously different from that of the simple contrast medium group( P
