AIM:To investigate the time course of nuclear factor-κB (NF-κB) and the effects of 3-aminobenzamide (3-AB) on the expressions of NF-κB,interleukin-1β (IL-1β) and cyclooxygenase-2 (COX-2) in hippocampus after seizures. METHODS:Epilepsy were induced by kainic acid through cerebral ventricular injection. Western blotting was used to detect NF-κB p65 expression in nucleus at various experiment groups. Moreover,mRNA and protein expressions of IL-1β and COX-2 in different experiment groups were determined by RT-PCR and Western blotting analysis. RESULTS:NF-κB p65 immunoreactivity began to increase in the nuclear fraction at 2 h (P<0.05),kept rising at 12 h (P<0.05) and returned to control level at 24 h after epilepsy seizures. Furthermore,3-AB sharply decreased the accumulation of NF-κB p65 in nucleus (P<0.05). In addition,3-AB significantly decreased the mRNA and protein expressions of IL-1β and COX-2 which obviously increased in hippocampus at 6 h after epilepsy seizures (P<0.05). CONCLUSION:Seizures triggers NF-κB nucleus translocation and promotes the expressions of IL-1β and COX-2 in hippocampus. In addition,poly (adenosine diphosphate-ribose) polymerase inhibition by 3-AB suppresses NF-κB associated inflammatory pathway in epileptic rat hippocampus.

Objective To study the role of gap junctions in epileptiform activity. Methods The epileptiform activity was induced by zero-Mg 2+ medium in cultured hippocampal neurons of newborn rats. Immunocytochemistry and real time RT-PCR were introduced to evaluate the expression of gap junction Cx32 and Cx43. Results The level of Cx32 mRNA increased quickly one hour after the neurons were treated with zero-Mg 2+ medium and was raised by 10 times 5 hours later, while Cx32 protein began to develop at the 2nd hour (21.80?1.74) and was raised by 5 times at the 8th hour (47.30?5.75). The expression of Cx43 mRNA went up obviously 5 hours later, and Cx43 protein developed visibly 8 hours later. Carbenoxolone depressed the expressions of Cx32 and Cx43. Conclusions The expression of Cx32 and Cx43 increases dramatically after epileptic discharges and carbenoxolone inhibits both the discharges and the expression of gap junctions, which indicates that gap junction could contribute to epileptogenesis.

Objective To explore the mechanisms of angiotensin Ⅱ (Ang Ⅱ) induced apoptosis of cultured cardiomyocytes of neonatal rats. Methods Cultured neonatal rat cardiomyocytes were divided into three groups. Cells in the control group were incubated in serum-free medium for 2, 6, 12, and 24 h. Cells in Ang Ⅱ group were incubated with Ang Ⅱ at the dose of 10 -7 mol/L for 2, 6, 12, and 24 h. Cells in Ang Ⅱ and Ang Ⅱ type 1 receptor antagonist group were incubated in medium containing 10 -7 mol/ L Ang Ⅱ plus 10 -5 mol/L irbesartan. The apoptotic cells were detected by TUNEL assay. The Bcl-2 protein expression was assessed by immunohistochemistry. Caspase-3 activity was measured by a fluorescent assay kit. Results The number of apoptotic cells in Ang Ⅱ group increased significantly in a time-dependent manner, accompanied by decreased Bcl-2 protein expression but increased activity of caspase-3. Treatment with irbesartan resulted in decreased number of apoptotic cells and decreased activity of caspase-3. Conclusion Angiotensin Ⅱ could induce the apoptosis of neonatal rat cardiomyocytes through the caspase-dependent pathway, which might be mediated by Ang Ⅱ type 1 receptor. Bcl-2 may participate in the regulation.

OBJECTIVE:
To explore the effective of the new mechanical assistant canalith repositioning procedure (TRV-CRP) to the diagnosis and treatment of the benign paroxysmal positional vertigo (BPPV).
METHOD:
The data of the cases with suspected diagnosis of BPPV from April to June of 2012 checked and treated by TRV-CRP in our vestibular function checking room were collected and analyzed. All of the cases were followed up to one to three months.
RESULT:
Total 504 cases of suspected diagnosis of BPPV were collected. Three cases were rejected for un completed procedure. All of the 501 completed procedure cases included 162 male and 339 female with age ranging from 10 years old to 86 years old (52. 8 +/- 14 years old). 169 cases (33.73%) were positive diagnosis and 332 cases were negative diagnosis (66.27%). 135 cases enrolled only one semicircular canal (SC) account for 79.89% of all the positive diagnosis that included 17 cases of left horizontal SC, 4 cases of left superior SC, 29 cases of left posterior SC, 23 cases of right horizontal SC, 4 cases of superior SC and 58 cases of right posterior SC. 25 cases enrolled more than two SC (14.80%). 9 cases of objective BPPV (5.33%) included 5 cases of right posterior SC, 3 cases of left posterior SC and one cases of right horizontal SC. Exception of 163 cases without classic BPPV history in the 332 negative diagnosis cases, 169 cases had classic BPPV history including 14 cases treated by manual canalith repositioning procedure and 33 cases which had released from the vertigo. The rate of treatment effective by TRV-CRP was 100%. There were 20 cases returned for retreatment because their unsatisfied about the release of their symptom but proved to be negative diagnosis again in 10 cases and positive diagnosis in 10 cases, however, only 4 cases proved to be the same SC disease were considered as relapse (2.37%) and others enrolled different SC. After retreated, all cases got release without relapse.
CONCLUSION
TRV-CRP could diagnosis 34% of the primary diagnosis cases of BPPV. TRV-CRP had high rate of effective and lower relapse which especially fitted to patients suffered from complex BPPV or difficult to finish the manual repositioning procedure. However, due to the expensive of TRV-CRP, it is reasonable to combine TRV-CRP and manual repositioning procedure in clinical.
