Allergic rhinitis is a common disease, which was released by the IgE-mediated atopic individuals exposed to allergens in the earlier researches. However, there are variety of immunocompetent cells and cytokines involved in the nasal mucosa immunologic mechanism in nowadays researches. The mechanism of AR is caused by the imbalance of the Th1/Th2, a kind of allergic inflammation who is characterized by the nasal Th2 immune response dominant. Th1 cells mainly produce of IFN-gamma (does not include IL-4 and IL-5), Th2 cells produce IL-4, IL-5, IL-9 and IL-13 (not including IFN-gamma). Recently it was found that regulatory T cells (T regulatory cells, Treg) and Th17 cell research played a crucial role in the occurrence of allergic inflammation.

AIM: To explore the way and the feasible time of olfactory ensheathing cells (OECs) transplanting to experimental autoimmune encephalomyelitis (EAE) rats, and to investigate the migration of OECs after transplanted to EAE and the possible mechanism of inducing the protective effect. METHODS: The Lewis rats, which were divided into MOG group and GPSCH group according to the induction by MOG~Igd and GPSCH separately, were used to made EAE model. The animals in MOG group were divided into 3 subsets: OECs blank group (MOG0 group, 4 rats );OECs transplantation by vena caudalis (MOG1 group, 7 rats);OECs transplantation by lateral cerebral ventricle (MOG2 group, 4 rats). The animals in GPSCH group were also divided into 2 subsets: OECs blank group (GPSCH0 group, 4 rats);OECs transplanted by vena caudalis (GPSCH1 group, 4 rats). OECs transplanted through different ways in peak incidence, then the rats were measured to determine whether the symptom was ameliorated. Two weeks after transplantion, the rats were killed and the methods of histofluorescence and histopathology (HE staining and Luxol fast blue staining) were used to examine the distribution of the labeled OECs in EAE rats' bodies and to explore whether there was some amelioration in histology. RESULTS: After OECs transplantation by vena caudalis or lateral cerebral ventricle, the rats' symptom improved. Compared to OECs blank groups, there was significant difference in clinical scores (F=18.470, P<0.01;t=-7.147, P<0.01). No significant difference between MOG1 group and MOG2 group was observed (P>0.05). The labeled OECs entered into the brain through the broken blood-brain-barrier after transplantation by vena caud-alis, the labeled OECs near the subpial area and around the lesions were found. OECs transplantation by the way of lateral cerebral ventricle showed great migration potential, the cells moved towards to the lesions extensively. No significant difference between OECs transplantation group and OECs blank group in histopathology (HE staining and LFB staining) was observed (P>0.05), and the same thing also happened between MOG1 group and MOG2 group (P>0.05). CONCLUSION: The transplantation of adult rats' OECs improves the EAE rats' symptom at some degree by the ways of vena caudalis or lateral cerebral ventricle.

Objective To investigate the prevalence of sleep-disordered breathing in elderly patients with permanent cardiac pacemaker implantation due to bradyarrhythmias, and the relationship between pacing mode and patients' sleep apnea-hypopnea index.Methods Forty-four elderly patients (>60 years) with cardiac pacemaker and their 44 controls matched for gender, age, body mass index and cardiovascular morbidity were studied using polysomnography or portable sleep monitoring device. Results Prevalence of sleep-disordered breathing (apnea-hypopnea index ≥5/h) was 44.7% and the mean apnea-hypopnea index was 8.2 ±4.1/h in the cardiac pacemaker group, which were significantly higher than those in control subjects (25% and 4.6±2.4/h, respectively, P<0.01 and P<0.05). The mean apnea-hypopnea index of patients with DDD or AAI pacemaker was significantly lower than that of patients with VVI pacemaker. Conclusions Sleep-disordered breathing was more common in patients who had their cardiac pacemaker implanted due to bradyarrhythmias than in their matched controls. Compared with VVI pacing, DDD or AAI pacing may be more beneficial to patients with bradyarrhythmias and sleep-disordered breathing.
