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 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.

BACKGROUND:Adipose-derived mesenchymal stem cels are a kind of pluripotent stem cels that have the potential of self-renewal and proliferation, and have low immunogenicity and immunomodulatory role. OBJECTIVE:To study the effects of adipose-derived mesenchymal stem cels on T cel immune status of alergic rhinitis mouse models.
METHODS:Sixty mice were randomly assigned into six groups (sensitized/chalenged/treatment): experimental group 1 was given ovalbumin/ovalbumin/high-dose adipose-derived mesenchymal stem cels, experimental group 2 given ovalbumin/ovalbumin/low-dose adipose-derived mesenchymal stem cels, experimental group 3 given ovalbumin/ovalbumin/PBS, experimental group 4 given ovalbumin/ovalbumin/0, and experimental group 5 given PBS/PBS/0, and normal control group given no treatment. In the former five groups, intraperitoneal injection of 200 μL ovalbumin sensitizing solution or PBS was conducted for basic sensitization at days 0, 7, 14; 20 μL ovalbumin chalenging solution or PBS was given for chalenging at days 15-19. In the former three groups, 0.1 mL of high-dose, low-dose adipose-derived mesenchymal stem cels or PBS was givenviathe tail vein, respectively, at days 20-22 after sensitization and chalenge. At 48 hours after final treatment, ELISA was used to detect serum levels of interleukin-4, interleukin-6, interleukin-10 and interferon-γ, and fluorogenic quantitative PCR used to detect the mRNA expressions of these cytokines in the spleen. Migration of fluorescent-labeled adipose-derived mesenchymal stem cels in the nasal mucosa was observed under fluorescence microscope, and pathological changes of the nasal mucosa were observed through hematoxylin-eosin staining.
RESULTS AND CONCLUSION:Compared with the experimental group 4, the levels of interleukin-4 and interleukin-6 in the serum and spleen were significantly lower in the experimental group 1 (P< 0.05), and the levels of interluekin-10 and interferon-γ levels were significantly increased (P <0.05); while in the experimental group, the levels of interleukin-6 were reduced significantly (P < 0.05), the levels of interleukin-10 was increased significantly (P< 0.05), but no changes were found in the levels of interleukin-4 and interferon-γ (P> 0.05). Fluorescent-labeled adipose-derived mesenchymal stem cels could migrate into the nasal mucosa, and the number of migrated cels was notably higher in the experimental group 1 than experimental group 2. Eosinophil infiltration in the nasal mucosa was remarkably aleviated in the experimental groups 1 and 2. These findings suggest that adipose-derived mesenchymal stem cels play a non-specific immunomodulatory effect dose-dependently by regulating Th1/Th2 immune imbalances and deficiencies of Treg cels.
