摘要
Objective:To analyze the genetic and environmental factors that may contribute to the development of allergic rhinitis (AR) in patients, and provide a scientific basis for formulating intervention measures.Methods:This is a case-control study. A cross-sectional survey was conducted on AR patients who received treatment at The First Affiliated Hospital of Nanchang University from June 2017 to March 2019 using a self-designed questionnaire on AR susceptibility factors. Logistic regression analysis of AR susceptibility factors was performed.Results:There were 242 patients in the AR group and 258 patients in the non-AR group (control group). The average age of all patients was (13.16 ± 5.63) years. 56.8% of included patients were male. Multivariate logistic regression analysis showed that AR onset was associated with neonatal jaundice ( OR = 6.043), respiratory infections within 6 months after birth ( OR = 8.123), diarrhea ( OR = 3.868), eczema ( OR = 4.540), living in urban areas ( OR = 2.477), home decoration after birth ( OR = 3.042), moldy ceilings or walls ( OR = 38.255), home gardening ( OR = 3.752), and exposure to smoking environments ( OR = 2.574). Conclusion:The etiology of AR is complex, and its onset is influenced by various factors such as genetic factors, environmental factors, and related disease factors. It is necessary to strengthen the promotion and education of AR prevention knowledge, pay attention to environmental hygiene, and take personal protection measures.

Objective:To compare the clinical value of visual analogue scale （VAS）, Lebel scale and total nasal symptom scores （TNSS） in evaluating nasal allergen provocation test （NAPT）. Methods:A total of 151 patients suspected of allergic rhinitis admitted to the Department of Otolaryngology-Head and Neck Surgery of our hospital from April 2020 to September 2020 were included, of which 76 were positive for house dust mites and 75 were negative for allergens. Nasal airway resistance（NAR） was measured by active anterior nasal manometry. Nasal symptoms were evaluated by VAS, Lebel and TNSS. House dust mite allergen was used for NAPT by spray method. An increase≥40% in NAR was used as the gold standard for objective evaluation of NAPT. ROC curves of VAS, Lebel and TNSS were drawn to compare the evaluation effectiveness of different subjective evaluation methods, and the optimal critical point of each ROC curve was obtained. Results:With NAR increased by ≥40% as the gold standard, the area under ROC curve of VAS was 0.884, and the sensitivity and specificity were 97.75% and 80.65%, respectively. The area under ROC curve of Lebel was 0.773, and the sensitivity and specificity were 68.54% and 75.81%, respectively. The area under ROC curve of TNSS was 0.792, and the sensitivity and specificity were 68.54% and 79.03%, respectively. There was no significant difference between Lebel and TNSS（P>0.05）. The VAS differed significantly from Lebel and TNSS（P<0.05）. The Kappa values of VAS, Lebel, TNSS and NAR were 0.803, 0.432 and 0.459, respectively. Conclusion:The VAS, Lebel, TNSS subjective scale and NAR are consistent in evaluating the efficacy of NAPT, with the VAS assessment showing highest consistency with NAR. As objective assessment instruments are not widely used in China, subjective assessment method could be adopted to evaluate the efficacy of NAPT in clinical practice, and VAS scale is recommended as a priority.

Objective To investigate the moist healing dressing nasal packing for epistaxis patients′physiological comfort and complications. Methods 70 patients of epistaxis patients with nasal packing by drawing lots were divided into A, B two groups of 35 cases. Group A used Vaseline gauze, and group B used moist healing dressings of composite fillings. Comparison of the two groups of pain, nasal odor, sleep disorders, hemostatic effect, nasal mucosa reaction, fever, nasal adhesions were conducted. Results Patients when nasal packing group A pain, sleep disorders and nasal odor scores were (9.80 ± 0.12), (7.10 ± 0.33) and (9.44 ± 0.25) points, group B were (3.82 ± 0.16), (3.22 ± 0.16) and (0.37 ± 0.09) points. Group A scored significantly higher than group B, the difference was statistically significant (t=-179.97,-7.22,-7.33, P <0.05). Group A fever and nasal adhesions were 33 cases and 6 cases respectively, while those figures in group B both were 0, the difference was statistically significant (χ2=62.43, 6.56, P<0.05). Conclusions Nasal packing varying degrees of discomfort in patients, the use of moist healing dressings for epistaxis targeted composite filling, can significantly increase the patients ’ physiological comfort and reduce the complications of nasal packing.

<p><b>OBJECTIVE</b>To determine the distribution of allergens in patients with allergic rhinitis in Nanchang area and provide the clinical reference for management strategies with regional character.</p><p><b>METHODS</b>Patients with symptoms of allergic rhinitis were given skin prick test (SPT) from March 2012 to May 2013. Among the patients, the distribution of all allergens was analyzed. The positive rate was compared with gender, age, occupation, season, course of disease and so on.SPSS 17.0 software was used to analyze the data.</p><p><b>RESULTS</b>Among 5 654 patients, the total positive rate of SPT was 56.07%, with dermatophagoides pteronyssinus (46.94%), dermatophagoides farina (35.99%), blomia tropicalis (31.34%) as the major allergens. With age increasing, the positive rate of allergen decreased. There was statistically significant difference (χ² = 261.372, P < 0.01) . There was significant difference of the positive rate in different occupations (χ² = 170.859, P < 0.01), the highest rate was found in student (66.12%) and the lowest was found in farmer (41.56%). There was significant difference of variation with months (χ² = 227.333, P < 0.01), the most in October, 68.88%. There was significant difference of the positive rate of dust mites in different seasons (χ² = 204.343, P < 0.01), the highest in autumn, the lowest in winter. There was no correlation between the positive rate and course of disease (P > 0.05).</p><p><b>CONCLUSIONS</b>Dust mites were identified as the most common allergens among patients with allergic rhinitis in Nanchang area.Occupation is one of the influencing factors for the positive rate.</p>

OBJECTIVE@#To observe the adverse effects of specific immunotherapy (SIT) with standardized dust mite allergen preparation in the treatment of allergic rhinitis.@*METHOD@#Three hundred and eighty-six patients with allergic rhinitis who received subcutaneous SIT with a standardized dust mite allergen preparation were enrolled in this study. The patients were treated for at least 15 weeks,adverse effects after each injection from dosing phase to maintenance phase were recorded and incidence of adverse effects were analyzed.@*RESULT@#Of all the patients,adverse reactions occurred in 42 patients (10. 9%),10 local reactions (2. 6%) and 36 systemic side effects (9. 3%) which included 34 mild ,1 moderate and 1 severe side effects (no fatal) were reported respectively. None had anaphylactic shock. Among three treatment options, incidence of routine program was the highest (21.1%),followed by adult cluster program (11. 9%), adverse effects of children cluster program was the least (1. 5%). The adverse effects often happened in the middle and late phase of does addition period and early phase of maintenance period.@*CONCLUSION@#SIT with standardized dust mite allergen preparation in the treatment of allergic rhinitis is a safe and effective treatment by complying with the guidelines and taking specific interventions.
