Objective:To investigate the effect of posterior nasal neurectomy（PNN） with pharyngeal neurectomy （PN） on chronic sinusitis with nasal polyps （CRSwNP）complicated with perennial allergic rhinitis （PAR）. Methods:83 patients with perennial allergic rhinitis combined with chronic group-wide sinusitis with nasal polyps who attended our hospital from July 2020 to July 2021 were selected. All patients underwent conventional functional endoscopic sinusitis surgery（FESS）+ nasal polypectomy. Patients were divided according to whether they underwent PNN+PN. 38 cases in the experimental group underwent FESS combined with PNN+PN; 44 cases in the control group underwent conventional FESS alone. All patients underwent the VAS, RQLQ, and MLK before treatment, and at 6 months and 1 year after surgery. Meanwhile, other relevant data were collected and the preoperative and postoperative follow-up data were collected and analyzed to assess the differences between the two groups. Results:The total postoperative follow-up period was 1 year. The recurrence rate of nasal polyps at 1 year postoperatively and the nasal congestion VAS score at 6 months postoperatively were not statistically significant in the two groups（P>0.05）. However, the patients in the experimental group had statistically significantly lower effusion and sneezing VAS scores, MLK endoscopy scores and RQLQ scores at 6 months and 1 year postoperatively, and nasal congestion VAS scores at 1 year postoperatively compared to the control group（P<0.05）. Conclusion:For patients with perennial AR complicated with CRSwNP, the combination of the PNN+PN in FESS can significantly improve the short-term curative effect, and PNN+PN is a safe and effective surgical treatment.

Objective: Transcriptome sequencing and bioinformatics analysis were performed on the gene expression of nasal epithelial cells in patients with seasonal allergic rhinitis (AR) and perennial AR, so as to obtain the differences in the gene expression of nasal epithelial cells between seasonal AR and perennial AR. Methods: The human nasal epithelial cell line(HNEpC) was cultured in vitro, treated with 100 μg/ml mugwort or house dust mite (HDM) extracts for 24 hours. Total cell RNA was extracted, and quantitative real-time polymerase chain reaction (qPCR) was used to detect the expression of cytokines, including IL-6, IL-8, IL-33 and thymic stromal lymphopoietin (TSLP). From November 2019 to November 2020, 3 seasonal AR patients, 3 perennial AR patients, and 3 healthy controls who attended the Department of Otolaryngology Head and Neck Surgery, China-Japan Union Hospital of Jilin University were analyzed. The patients' primary nasal epithelial cells were cultured in vitro, treated with corresponding allergens for 24 hours. Total RNA was extracted for transcriptome sequencing, and the sequencing results were analyzed by bioinformatics. Results: The qPCR results showed that the cytokines IL-6, IL-8, IL-33 and TSLP of HNEpC treated with mugworts extracts and HDM extracts had the same trend of change. After the nasal epithelial cells from patients with seasonal AR and perennial AR were treated with corresponding allergens, there were differences in biological processes and signal pathways between those and control. Gene ontology (GO) enrichment analysis showed that the differentially expressed genes (DEG) in AR patients allergic to mugwort were mainly enriched in the oxidation-reduction process, the negative regulation of apoptosis process, and the cell adhesion; the DEG in AR patients allergic to HDM were mainly enriched in cell adhesion, the negative regulation of cell proliferation and the response to drug. Enrichment analysis of Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathway showed that the DEG of AR patients allergic to mugwort were significantly enriched in arachidonic acid metabolism, p53 signaling pathway and transforming growth factor β (TGF-β) signaling pathway, while the DEG of AR patients allergic to HDM were mainly enriched in cells cycle, Fanconi anemia pathway and DNA replication. Gene Set Enrichment Analysis (GSEA) showed that the inflammatory response, TNF-α/NF-κB signaling pathway and IL-2/STAT5 signaling pathway were significantly up-regulated in AR patients allergic to mugwort, indicating the promotion of inflammatory response; and AR patients allergic to HDM had significant down-regulation of G2M, E2F, and MYC, indicating the inhibition of cell proliferation. The protein-protein interaction network showed that TNF and CDK1 were the most interacting proteins in mugwort and HDM allergic AR patients, respectively. Conclusion: Seasonal AR and perennial AR may affect the different biological processes and signal pathways of nasal epithelial cells, leading to differences in the occurrence and development of AR.

PURPOSE: The study aims to classify schools based on traffic pollutants and their complex sources, to assess the environment, to determine the state of allergic diseases among students using the International Study of Asthma and Allergies in children (ISAAC) questionnaire, and to assess their connection to air pollutants. MATERIALS AND METHODS: A total of seven schools were divided into three categories according to the characteristics of their surrounding environments: three schools in traffic-related zones, two schools in complex source zones I (urban), and two schools in complex source zones II (industrial complex). ISAAC questionnaires were administered and the 4404 completed questionnaires were analyzed. RESULTS: The frequency of asthma treatment during the past 12 months showed a significant increase (p<0.05) with exposure to NO2 [1.67, 95% confidence intervals (CIs) 1.03-2.71] in the complex source zones. The frequency of allergic rhinitis treatment during the past 12 months increased significantly with exposure to Black Carbon (1.60, 95% CIs 1.36-1.90) (p<0.001), SO2 (1.09, 95% CIs 1.01-1.17) (p<0.05), NO2 (1.18, 95% CIs 1.07-1.30) (p<0.01) for all subjects. CONCLUSION: In terms of supporting children's health, care, and prevention related to major spaces for children, such as school zones, spaces used in coming to and leaving school, playgrounds, and classrooms are essential to ensuring not only the safety of children from traffic accidents but also their protection from local traffic pollutants and various hazardous environmental factors.

OBJECTIVE: To evaluate the efficacy of sublingual immunotherapy (SLIT) with Dermatophagoides farinae drops for allergic rhinitis (AR) of different symptom severity. METHOD: This retrospective analysis to receive SLIT treatment of 143 cases of patients with allergic rhinitis, according to the severity of disease symptoms divid- ed into two groups, moderate group (62 patients) and severe group (81 patients). Before SLIT and after SLIT for half year, 1 year and 1. 5-2.0 years, the TNSS, TMS and sign scores of patients with allergic rhinitis were evaluated. RESULT: The TNSS, TMS and sign scores had continuously improved significantly after SLIT for half year, 1 year and 1.5-2.0 years in two groups as compared with baseline (P < 0.05). Before SLIT, TNSS and sign scores of severe group had a significantly higher level than moderate group (Z = 10.40, 2.40, P < 0.05), while TMS of two groups had no significant differences (Z = 0.00, P > 0.05). Half year after SLIT treatment, in two groups for sign scores, there were significant differences (Z = 3.32, P < 0.05), and there were no significant differences for TNSS (Z = 1.58, P > 0.05) and TMS (Z = 0.37, P > 0.05). 1 and 1.5-2.0 years after SLIT, there were no significant differences in two groups for TNSS, TMS and sign scores (P > 0.05). CONCLUSION SLIT with Dermatophagoides farinae drops for 1.5-2.0 years is effective in the patients with allergic rhinitis of different symptom severity. And equivalent efficacy could be achieved for different symptom severity.
