Allergic rhinitis has been considered to be the most frequent form of chronic rhinitis, as non-allergic rhinitis has been estimated to account for 25%. However, several evidences suggested that non-allergic rhinitis have been underrated, especially in children. In pediatrics, the diagnostic definition of non-allergic rhinitis has been often limited to the exclusion of an allergic sensitization. Actually, local allergic rhinitis has been often misdiagnosed as well as mixed rhinitis has not been recognized in most cases. Nasal cytology is a diagnostic procedure being suitable for routine clinical practice with children and could be a very useful tool to characterize and diagnose non-allergic rhinitis, providing important clues for epidemiological analysis and clinical management.展开更多

Methods： A non-randomized controlled design was used to compare between the acupuncture group and the medication group. The acupuncture group received 8-week acupuncture therapy, and the medication group received budesonide nasal spray with cetirizine tablets for 8 weeks. The clinical symptoms and signs were analyzed before treatment, at 4 and 8 weeks after the start of treatment, and at 12 weeks after the end of treatment. Furthermore, the clinical efficacy and safety indicators were compared between the two groups. Results： A total of 76 participants consisting of 38 in each of the two groups were enrolled. The scores of each clinical symptom and sign, including sneezing, runny nose, stuffy nose, nasal itching, and turbinate edema, and the total scores decreased over time in both groups （all P〈0.05）; and no difference was found in the scores between the two groups （P〉0.05）. There was no statistically significant difference in the effective rates of the acupuncture group at 4 and 8 weeks after the start of treatment as well as at 12-week follow-up compared with those of the medication group （83.3% vs. 91.2%, and 94.4 % vs. 85.3%; and 80.6 % vs. 82.4%, all P〉0.05）. Experimental items including blood routine, urine routine, aspartate transaminase, alanine aminotransferase, urea nitrogen and creatinine were all in the normal reference ranges during the treatment in the acupuncture group. Conclusions： Acupuncture therapy has a comparable effect to the medication treatment on patients with moderate to severe allergic rhinitis, and it is safe with no severe adverse effects.展开更多

Quantitative methods are required for diagnosis of nasal obstruction to accurately assess drug efficacy, not only in patients but also in animal models. Acoustic rhinometry is a non-invasive technique to measure nasal airway patency using acoustic reflections. To date, little information on its application in non-human primates (NHP) has been accumulated. Macaque monkeys are a practical NHP model because of their high similarity with humans in their biomedical nature, including genomic and immunologic events and morphology. We established an allergic rhinitis model of cynomolgusmacaque (Macaca fascicularis) sensitized with Japanese cedar pollen and applied acoustic rhinometry to measure nasal congestion. The extent of nasal congestion followed by allergen challenge was successfully quantified as the minimal cross-sectional area (MCA) of the nasal passage for the first time in an NHP allergic model. We also applied this acoustic technique to evaluate the efficacy of an antihistamine drug, fexofenadine. The acoustic assessment achieved quantitative evaluation of the efficacy of fexofenadine on nasal congestion in a macaque allergic model.展开更多

The localization of caspases in nasal polyps and nasal hyperplasia of patients with and without allergic rhinitis was studied. Methods: Sections of human nasal polyps (n = 5) and hyperplastic nasal turbinates (5 with, 5 without allergy) were stained for active caspase-3 and caspase-8. Double immunofluorescence was used to evaluate colocalization of the caspases with Ki-M1P and tryptase. TUNEL was performed. Results: Active caspase-3 and caspase-8 were seen in nearly all nasal polyps and hyperplastic nasal turbinates. Active caspase-3 was predominantly localized in stromal cells, identified as mast cells. Caspase-8 was localized in mast cells with the pattern similar to active caspase-3 and additionally found in epithelial cells at the nasal and polyp surface and in epithelial cells of glands. Conclusion: Our results suggest that mast cell apoptosis may be involved in the pathological mechanisms which characterize and sustain chronic inflammatory disorders of the nasal mucosa with and without allergy.展开更多
