Traditional Chinese Medicine constitution among patients with allergic rhinitis and its correlation with anxiety and depression.

OBJECTIVE: To preliminary investigate the distribution of Traditional Chinese Medicine (TCM) constitution among patients with allergic rhinitis (AR) and reveal the related factors with anxiety and depression. METHODS: Between July 2020 and June 2021, specialist doctor recruited AR patients in Beijing and Shanghai. A total of 630 patients admitted to participate in the survey, and 516 (81.9%) (male 54.3%, female 45.7%) participants completed the questionnaires. Three scales including Constitution in Chinese Medicine Questionnaire (CCMQ), Generalized Anxiety Disorder Questionnaire (GAD-7) and The Patient Health Queationaire-9 (PHQ-9) were applied. The χ2 and the Fisher's exact test were used to evaluate the classification data, multivariate logistic regression was used to explore the related factors of anxiety and depression. RESULTS: According to 516 AR patients, the most commonly first-constitution was Yang-deficiency (22.1%) and frequent of all constitutions was inherited-special (21.6%). One third of AR patients (33.5%) suffered from anxiety, nearly half of AR patients (46.5%) were found to be depressive. Inherited-special (27.7%) was the most common constitution in patients with anxiety whereas Yang-deficiency (26.7%) was most common constitution in patients with depression. Sex, duration of symptoms, balanced, Qi-deficiency, phlegm-dampness, Qi-stagnation, and inherited-special constitutions were related with anxiety; Sex, income, duration of symptoms, balanced, Qi-deficiency, Yang-deficiency, phlegm-dampness, Qi-stagnation, and inherited-special constitutions were related with depression. CONCLUSIONS: According to our study, the commonly constitution types of AR were Yang-deficiency and inherited-special. We found that the prevalence value of anxiety and depression were high. People with Qi-deficiency, phlegm-dampness, Qi-stagnation, and inherited-special constitutions were more likely to have mental problems than the others. Controlling these influential factors might be beneficial for clinical health management of AR patients, and the government should apply appropriate mental health treatment services to offer psychiatric support.

Associations of dietary vitamin A and C intake with asthma, allergic rhinitis, and allergic respiratory diseases.

BACKGROUND/OBJECTIVES: Asthma and allergic rhinitis (AR) are closely related and considered as allergic respiratory diseases (ARD), and their prevalence has recently increased. Data on the association of dietary antioxidant vitamin intake with asthma and AR in adults are limited. The present study aimed to investigate the associations of vitamin A and C intake with asthma, AR, and all cases of both diseases in young adults who participated in a cross-sectional national survey, with the use of high-sensitivity C-reactive protein (hs-CRP) level as an effect modifier. SUBJECTS/METHODS: This study included 6,293 male and female adults aged 20-49 years from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 2016 and 2018. The questionnaire-based reports on asthma and AR diagnosis were used to determine outcome variables. Further, 24-h recall data on dietary vitamin A and C, carotene, and retinol intake were acquired. Logistic regression analysis was performed to calculate odds ratios (ORs) and 95% confidence interval (CI). RESULTS: Dietary vitamin C intake was inversely associated with asthma prevalence among participants with hs-CRP levels (≥ 1 mg/L); the OR of asthma prevalence was 0.27 (95% CI, 0.08-0.84) for participants with vitamin C consumption ≥ 75 mg/day compared with those consuming < 20 mg/day. Similar association analyses limiting to non-users of dietary supplements were performed to rule out the potential effects of supplement intake on the outcomes; results showed a stronger association. However, the association between vitamin C and asthma was not significant in participants with hs-CRP levels < 1 mg/L; the OR of asthma was 1.44 (95% CI, 0.66-3.16) for participants with vitamin C consumption ≥ 75 mg/day compared with those consuming < 20 mg/day. Vitamin C intake was not associated with AR. Moreover, there was no association between vitamin A intake and neither asthma nor AR. CONCLUSIONS: These findings suggest that higher vitamin C intake may play a potential role in reducing asthma prevalence. Nevertheless, further studies should be conducted to evaluate whether this association is causal.

Efficacy of catgut embedding in Baihui (GV20) and Feishu (BL13) and Pishu (BL20) on lung tissue, brain tissue and blood related indexes in rats with allergic rhinitis of lung deficiency type.

OBJECTIVE: To investigate the effects of acupoint catgut embedding for 3 weeks on lung tissue, blood immunoglobulin E (IgE) and interleutin-4 (IL-4), brain tissue microglia x-42 (OX-42) and toll-like receptor-2 (TLR-2) in rats with allergic rhinitis of lung deficiency type. METHODS: Forty-five female Sprague-Dawley rats were randomly divided for two times. The first time, they were randomly divided into model group and blank group (Group C) according to 2:1, and the second time, the model group were randomly divided into model control group (Group B) and intervention treatment group (Group A) according to 1:1. 15 in each group. For Group A and Group B, the lung deficiency model was made by "sulfur-moxa fumigation", and then the allergic rhinitis model was established by "ovalbumin (OVA) sensitization". Then catgut embedding was performed at acupoints in Group A and not in Group B. After 3 weeks, collect lung tissue samples for hematoxylin-eosin staining, then take blood to observe the concentration of IgE and IL-4, and finally take brain tissue to observe the results of OX-42 and TLR-2. RESULTS: IgE level (µg/mL) was (3.11 ± 0.20) in the Group A, (4.19 ± 0.44) in the Group B, and (2.29 ± 0.30) in the Group C (all < 0.001). IL-4 level (pg/mL) was (14.2 ± 0.7) in the Group A, (18.6 ± 2.4) in the Group B, and (11.4 ± 1.2) for the Group C (all < 0.001). The mean OD for OX-42 is (0.1728 ± 0.0016) in the Group A, (0.1810 ± 0.0046) in the Group B and (0.1674 ± 0.0025) in the Group C (all < 0.001). CONCLUSION: Although 3 weeks of acupoint catgut embedding already showed obvious efficacy on rats with allergic rhinitis, the allergic reaction in the body still continued. To achieve further treatment, prolonging the catgut embedding time is necessary.

[Distribution characteristics and results of allergens in patients with allergic rhinitis in Ningxia area].

Objective:To investigate the distribution of allergens in patients with allergic rhinitis （AR） in Ningxia, and provide theoretical data for the prevention and treatment of AR in this region. Methods:A total of 1664 patients diagnosed with AR in the Otorhinolaryngology Head and Neck Surgery Department of Yinchuan First People's Hospital Outpatient Clinic from January 2018 to December 2021 were retrospectively collected. Use the allergen sIgE antibody detection kit （immunoblotting method） to detect inhalation and ingestion allergens in patients.Results: ①Among all AR patients, 1 158 cases were detected positive, resulting in the detection rate was 69.59%; ②The detection rate of inhalation allergen was 65.87%, and the detection rate of ingestion allergen was 19.83%; ③Mugwort was the most sensitive allergen, and 76.32% of the patients having a positive grade ≥3; ④Out of the patients, 294 cases （25.39%） were allergic to only one allergen, 244 cases （21.07%） were allergic to two allergens, and 620 cases （53.54%） were allergic to three or more allergens; ⑤During different seasons, the highest number of positive allergens detected was in the summer, with 968 cases （83.59%）. Mugwort was the main allergen during this season （69.01%）. After the COVID-19 epidemic, the total positive rate of sIgE tests in AR patients decreased compared to before, and the difference was statistically significant （P<0.001）; ⑥Mugwort, dog epithelium, mold combination, egg, peanut, soybean, Marine fish combination and fruit combination all showed statistically significant differences between different gender groups （P<0.05）; ⑦Common ragweed, mugwort, dust mite combination, cockroach, egg, milk, Marine fish combination, shrimp, fruit combination and nut combination all showed statistically significant differences among different age groups （P<0.05）; ⑧There were statistically significant differences in hay dust among different ethnic groups （P<0.05）. Conclusion:Artemisia argyi is the main allergen in Ningxia, and the distribution characteristics of different allergens are influenced by treatment season, the COVID-19 epidemic, gender, age, ethnicity, and other factors, showing certain distribution patterns and rules.

Early intervention improves clinical responses to seasonal allergic rhinitis by stimulation in sphenopalatine ganglion (Xinwu acupoint).

OBJECTIVE: To examine the efficacy of early intervention (4 weeks before pollen dispersal) with sphenopalatine ganglion (Xinwu acupoint) stimulation in patients with allergies after the onset of seasonal allergic rhinitis (SAR). METHODS: This is a prospective, randomized and unblinded half-open study. Forty-one SAR volunteers were randomly assigned to either the sphenopalatine ganglion (SPG) acupuncture plus supplementary acupuncture (SPG group) or the sham-SPG acupuncture plus supplementary acupuncture (SA group) stimulation 4 weeks before the onset of allergy season. The changes of the total nasal symptom score (TNSS) and the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores were measured on the first week in the onset of allergy season. RESULTS: Four patients dropped out due to local hematoma and pain in the SPG and SA groups. The remaining 37 patients continued through to the end of the trial. After early intervention 4 weeks before the onset of allergy season, the sneezing, nasal congestion and itchiness scores in the first week of onset time were significantly lower in the SPG group than in the SA group patients ( 0.001). The RQLQ score obtained at the onset of symptoms indicated that symptoms were more significantly ameliorated in the SPG group than in the SA group (0.001). CONCLUSIONS: The results of this study confirmed that early intervention by sphenopalatine ganglion (Xinwu acupoint) stimulation can effectively improve the symptoms and the quality of SAR patients' daily lives.

KAAACI Allergic Rhinitis Guidelines: Part 2. Update in Non-pharmacological Management.

Allergic rhinitis is the most common chronic disease worldwide. Various upper airway symptoms lower quality of life, and due to the recurrent symptoms, multiple treatments are usually attempted rather than one definitive treatment. There are alternatives to medical (medication-based) and non-medical treatments. A guideline is needed to understand allergic rhinitis and develop an appropriate treatment plan. We have developed guidelines for medical treatment based on previous reports. The current guidelines herein are associated with the "KAAACI Evidence-Based Guidelines for Allergic Rhinitis in Korea, Part 1: Update in pharmacotherapy" in which we aimed to provide evidence-based recommendations for the medical treatment of allergic rhinitis. Part 2 focuses on non-pharmacological management, including allergen-specific immunotherapy, subcutaneous or sublingual immunotherapy, nasal saline irrigation, environmental management strategies, companion animal management, and nasal turbinate surgery. The evidence to support the treatment efficacy, safety, and selection has been systematically reviewed. However, larger controlled studies are needed to elevate the level of evidence to select rational non-medical therapeutic options for patients with allergic rhinitis.

Modulation of the Immune Response to Allergies Using Alternative Functional Foods.

Modulation of the allergic immune response through alternative therapies is a field of study that aims to address allergic reactions differently from traditional approaches. These therapies encompass the utilization of natural functional foods, which have been observed to exert an influence on the immune response, thus mitigating the severity of allergies. Indeed, some studies suggest that the incorporation of these nutraceuticals can regulate immune function, leading to a reduction in histamine release and subsequent alleviation of allergic symptoms. Moreover, certain herbs and dietary supplements, such as curcumin, are believed to possess anti-inflammatory properties, which may serve to moderate allergic responses. Although the results remain somewhat mixed and require further research, these alternative therapies exhibit the potential to impact the allergic immune response, thereby providing complementary options to conventional treatments. Therefore, in this review, we aim to provide an updated account of functional foods capable of modulating the immune response to allergies. In that sense, the review delves into functional foods sourced from plants (phytochemicals), animals, and marine algae. Emphasis is placed on their potential application in the treatment of allergic disorders. It also provides an overview of how these foods can be effectively utilized as functional foods. Additionally, it explores the molecular mechanisms and scientific validity of various bioactive natural compounds in the management of allergies.

Efficacy and safety of acupoint application for allergic rhinitis: a systematic review and Meta-analysis of randomized controlled trials.

OBJECTIVE: To use evidence-based medicine to explore the efficacy of acupoint application (AA) for allergic rhinitis (AR) at different time points and its safety. METHODS: We searched 7 databases (PubMed, Cochrane, Embase, China National Knowledge Infrastructure, Wanfang Database, China Science and Technology Journal Database, and China Biology Medicine disc) as well as the international clinical trial registration platform from January 2010 to March 2020 for randomized controlled trials (RCTs) comparing the efficacy of AA versus placebo, Western Medicine or other alternative therapies on AR. Risk of bias was assessed according to the Cochrane handbook, and statistical analysis was performed using RevMan 5.3. Outcomes included the total effective rate, recurrence rate, total nasal symptom score (TNSS), visual analogue scale (VAS), quality of life measured by the Rhinitis Quality of Life Questionnaire (RQLQ) or Short Form-36 (SF-36), adverse events, and biomarkers including immunoglobulin E (IgE), peripheral blood eosinophil count (EOS), interleukin-4 (IL-4), and interferon gamma (INF-γ). RESULTS: Twenty-eight RCTs involving 3282 participants were included. The short-term and long-term efficacy of AA was significantly better than placebo, including better total effective rate [: 3.05, 95% (1.84, 5.07), after treatment; : 9.29, 95% (2.57, 33.66), at 6 months], lower recurrence rate [: 0.55, 95% (0.45, 0.66), at 6 months; : 0.65, 95% (0.57, 0.74), at 1 year], lower TNSS [: -3.09, 95% (-3.58, -2.61), after treatment], and lower RQLQ [: -14.79, 95% (-21.49, -8.10), after treatment; : -11.92, 95% (-17.40, -6.45), at 4-6 months]. Compared with Western Medicine, AA had better long-term total effective rate [: 1.33, 95%CI (1.05, 1.69), at 3 months; : 1.49, 95% 1.22 to 1.81, at 1 year) and lower recurrence rate [: 0.48, 95% (0.39, 0.58), at 6 months; : 0.45, 95% (0.33, 0.60), at 1 year]. AA had better long-term total effective rate versus acupuncture [: 2.06, 95% (1.28, 3.31), at 1 year] or oral Chinese medicine [: 1.21, 95% (1.09, 1.34), ≥ 6 months]. Both AA and Western Medicine can reduce serum levels of IgE, EOS, and IL-4 after treatment. The main adverse event of AA was local skin reaction without systemic side effects. CONCLUSIONS: The short-term (within one month) and long-term (at 3 months, 6 months and 1 year) efficacy of acupoint application on AR was better than that of placebo. The long-term efficacy of acupoint application was superior to that of Western Medicine (at 3 months, 6 months and 1 year), oral Chinese medicine (at more than 6 months) and acupuncture (at 1 year). AA can reduce serum IgE, EOS, and IL-4 level of AR patients in a short run. Acupoint application is safe, but severe skin reactions can reduce patient compliance.

[Analysis on the allergic characteristics of humulus pollen in Beijing].

Objective:To understand the sensitization characteristics of humulus pollen in patients with allergic rhinitis or allergic asthma in Beijing, and to explore the proportion of the population allergic to humulus pollen. Methods:Selected 8380 patients who were diagnosed with allergic rhinitis, allergic asthma, and allergic rhinitis combined with asthma in outpatient clinic from January 2017 to December 2019. SPT test was performed with humulus allergen reagent to compare the sensitization distribution of humulus pollen by age and disease, and analyze the sensitization characteristics of humulus pollen. Results:The total positive rate of humulus pollen SPT reached 49.59%.The positive rate of humulus pollen SPT was the highest in the age group of 10 to 14 years old, reaching 71.98%, compared with other age groups, there was a statistical difference （P<0.01）; and the positive rate of SPT in patients under 10 years of age gradually increased with age, and the positive rate of SPT in patients over 50 years of age gradually decreased with age. Humulus pollen SPT positive patients ++++ and above accounted for 41.43%, which was significantly different from other groups （P<0.01）. Single humulus was less allergenic, accounting for about 23.87%. Most of them were combined with multiple pollen allergies （76.13%）, and often combined with chenopodiaceae pollen sensitization （92.81%）. Conclusion:The SPT positive rate of humulus pollen in patients with allergic rhinitis or asthma in Beijing area is nearly 50%. The positive rate of SPT is the highest among patients aged 10-14, and most of them show strong positive reactions. It is suggested that humulus pollen is the main allergen of allergic rhinitis and asthma, and the sensitization of humulus pollen tends to be multiple allergens.

Objective:To investigate the epidemiologic feature of allergic rhinitis （AR） in the grassland area of Xilin Gol League, in Inner Mongolia, including prevalence rate, clinical characteristics and main allergens, so as to provide scientific evidence for the prevention and treatment of AR. Methods:From May to August of 2015, in strict accordance with the requirements of epidemiological investigation, A multi-stage, stratified， random and cluster sampling method was adopted to investigate the population in three areas of Xilingol Grassland in Inner Mongolia （Xilinhot, Erlianhot and Duolun）, with a face to face questionnaire used to investigate the general situation, the main clinical symptoms and related symptoms of AR and the combined. Simultaneously, the skin prick test （SPT） of 10 common grassland allergens was carried out, and the gravity sedimentation method was used to monitor the daily pollen types and quantity in the area.SAS 9.4 software was used for data analysis． Results:A total of 2878 subjects in the cluster sample completed the questionnaire survey and allergen detection. The positive rate of SPT was 41.10% （1179/2787）, the self-reported prevalence rate of AR was 39.96%（1150/2878） and confirmed prevalence rate of AR was 22.72%（654/2878）. The most obvious clinical symptoms of AR were sneezing （91.13%, 1048/1150） and itchy nose （85.65%, 985/1150）. The most obvious clinical symptoms of ocular were itchy （55.13%, 634/1150） and tearing（42.96%，494/1150）. Fatigue and somnolence were prominent among other symptoms associated with AR. Among comorbidities, AR combined with conjunctivitis accounted for 60.52% （696/1150）, AR combined with asthma accounted for 13.57% （156/1150）. The major allergens of AR from high to low were Artemisia pollen, Chenopodium pollen, and Humulus pollen. The peak of AR symptoms mostly occuredin August.， and the peak period of allergic rhinitis symptoms coincided with the peak period of pollen quantity. Conclusion:The prevalence rate of AR in is extremely high due to the high seasonal pollen exposure in steppe area of Xilingol League in Inner Mongolian. Artemisia pollen is the main sensitized allergen.

The distribution of those allergens was different in gender, age, and different years.

Evaluation of bronchial challenge test results for use in assessment of paediatric eczema: a retrospective series.

BACKGROUND: Atopic dermatitis (AD), asthma, and allergic rhinitis are associated diseases involved in the atopic march. The bronchial challenge test (BCT) is a tool that evaluates airway hyperresponsiveness in patients with asthma. This study aimed to evaluate whether a positive BCT result is useful in assessment of paediatric AD. METHODS: This retrospective case series included 284 patients with AD who had BCT results. Clinical information and laboratory parameters were reviewed, including AD severity (using the SCORing Atopic Dermatitis [SCORAD]), skin hydration, and transepidermal water loss. RESULTS: Of the 284 patients who had BCT, 106 had positive BCT results and 178 had negative BCT results. A positive BCT result was associated with a history of asthma (P<0.0005), sibling with asthma (P=0.048), serum immunoglobulin E (P=0.045), eosinophil count (P=0.017), and sensitisation to food allergens in the skin prick test (P=0.027). There was no association between a positive BCT result and personal allergic rhinitis, parental atopy, sibling allergic rhinitis or AD, skin prick response to dust mites, objective SCORAD score, skin hydration, transepidermal water loss, exposure to smoking, incense burning, cat or dog ownership, or AD treatment aspects (eg, food avoidance and traditional Chinese medicine). Logistic regression showed significant associations of a positive BCT result with a history of asthma (adjusted odds ratio=4.05; 95% confidence interval=1.92-8.55; P<0.0005) and sibling atopy (adjusted odds ratio=2.25; 95% confidence interval=1.03-4.92; P=0.042). CONCLUSIONS: In patients with paediatric AD, a positive BCT result was independently and positively associated with personal history of asthma and sibling history of atopy, but not with any other clinical parameters.

Mild moxibustion plus loratadine tablets for children with allergic rhinitis: a randomized controlled trial / 针灸推拿医学（英文版）

Objective: To explore the efficacy of mild moxibustion plus loratadine tablets for children with allergic rhinitis (AR).Methods: A total of 80 children were randomized into a control group and an observation group, with 40 cases in each group. The control group was treated with loratadine tablets, and the observation group was treated with mild moxibustion plus loratadine tablets. Before and after treatment, the total nasal symptom score (TNSS) was evaluated, and the serum eosinophils (EOS) count, and the interleukin (IL)-27 and macrophage migration inhibitory factor (MIF) levels were measured. Clinical efficacy was evaluated after treatment. Results: The total effective rate of the observation group was higher than that of the control group (P<0.05). After treatment, the TNSS in both groups decreased (P<0.05), and the TNSS in the observation group was lower than that in the control group (P<0.05); the serum EOS count in both groups decreased (P<0.05), and the serum EOS count in the observation group was lower than that in the control group (P<0.05). The serum IL-27 level in the control group had no statistical difference compared with the same group before treatment (P>0.05), and the serum MIF level decreased after treatment (P<0.05). The serum IL-27 level in the observation group increased after treatment (P<0.05), and the serum MIF level decreased after treatment (P<0.05), and were both statistically different from those in the control group (P<0.05). Conclusion: Mild moxibustion plus loratadine tablets is effective in treating children with AR. It can significantly improve the nasal symptoms and reduce the serum EOS count, which may be related to the regulation of the serum IL-27 and MIF levels.

[ARIA 2019: An Integrated Care Pathway for Allergic Rhinitis in Portugal]. / ARIA 2019: Um Percurso Assistencial Integrado para a Rinite Alérgica em Portugal.

The Allergic Rhinitis and Its Impact on Asthma (ARIA) initiative started more than 20 years ago and has developed and disseminated evidence-based guidelines and projects in the field of allergic rhinitis. This initiative is currently focused on providing patient-centred guidelines that contribute to an integrated care pathway between the various levels of care and take advantage of digital solutions, and the introduction of integrated care pathways in clinical practice has been recommended. In this article we describe the adaptation for Portugal of the ARIA Integrated Care Pathways document. After a brief review of the epidemiology and impact of allergic rhinitis in Portugal and the activities carried out in Portugal within the ARIA initiative, we describe the broad knowledge base used for the development of recommendations for the pharmacological treatment of allergic rhinitis, and these recommendations are based on the GRADE methodology, real world evidence acquired by mobile technology (mHealth) and resulting from allergenic exposure chamber studies. What follows is a summary of integrated care pathways for allergen immunotherapy produced in 2019. Allergen immunotherapy is considered an example of precision medicine where the use of mHealth technologies will improve stratification for patient selection and response monitoring. These recommendations were considered as best practices of integrated patient-centred care supported by digital systems from Directorate General for Health and Food Safety of the European Union (DG Santé) and represent the ARIA Phase 4 Change Management strategy.

A iniciativa Allergic Rhinitis and Its Impact on Asthma (ARIA) teve início há mais de 20 anos e tem elaborado e disseminado orientações baseadas em evidência, e desenvolvido projetos na área da rinite alérgica. Esta iniciativa está atualmente focada em proporcionar orientações centradas no doente que contribuam para um percurso integrado entre os vários níveis de cuidados e que tirem partido de soluções digitais, tendo sido recomendada a introdução na prática clínica de percursos assistenciais integrados. Neste artigo descrevemos a adaptação para Portugal do documento ARIA Integrated Care Pathways. Após breve revisão sobre a epidemiologia e o impacto da rinite alérgica em Portugal e das atividades realizadas em Portugal no âmbito da iniciativa ARIA, é descrito o conjunto alargado de conhecimento utilizado para o desenvolvimento das recomendações para o tratamento farmacológico da rinite alérgica, recomendações essas baseadas na metodologia GRADE, evidência do mundo real adquirida por tecnologia móvel (mHealth) e resultante de estudos de câmara de exposição alergénica. Em seguida, são resumidos os percursos assistenciais integrados para imunoterapia com alergénios produzidas em 2019. Considera-se a imunoterapia com alergénios um exemplo de medicina de precisão e em que a utilização de tecnologias mHealth permitirá melhorar a estratificação para seleção dos doentes e monitorização da resposta. Estas recomendações foram consideradas como 'boas práticas' dos cuidados integrados centrados no doente apoiados por sistemas digitais da DG Santé (Direção Geral de Saúde e de Segurança Alimentar da União Europeia) e representam a estratégia de gestão da mudança da fase 4 do ARIA.

[Allergens analysis in patients with allergic rhinitis in Rikaze].

Objective:To investigate the distribution of allergens in patients with allergic rhinitis（AR） in Rikaze. Method:A retrospective analysis was performed in patients with AR diagnosed by skin prick test （SPT） between June 2017 and June 2018 from Rikaze People's Hospital. Result:One hundred and thirty-one patients were diagnosed with AR using SPT. The most common inhalant allergens were pollen, including Artemisia sieversiana willd（64.8%）, Artemisia annua L. （64.1%） and Humulus Scandens（45.8%）, while soybean（17.6%）, mango（15.3%） and carp（12.2%） were the most common food allergens. Conclusion:The most common inhalant allergens in patients with AR is the pollen in Rikaze area.

[Quality of life survey of patients with allergic rhinitis caused by airborne pollen in Inner Mongolia].

Objective:To study the quality of life of patients with allergic rhinitis（AR） caused by airborne pollen in Inner Mongolia, and provide reference for overall health intervention for AR patients. Method:According to the severity of disease, 268 cases of patients was divided into mild and moderate to severe group. The patients general condition questionnaire, standardized rhinoconjunctivitis quality of life questionnaire（RQLQ）, quality of life questionare-core30（QOL-C30） were used to assess the quality of life of AR patients. At the same time 90 healthy volunteers with no symptoms of nasal（balanced gender, age） were recruited as control group. Result:In the intra-group comparison of the RQLQ questionnaire for AR patients, the total score of the RQLQ questionnaire and the 7 factor scores in the moderate to severe groups were significantly higher than those in the mild group（all P<0.05）. The QOL-C30 survey showed that the scores of the four dimensions of QOL-C30 assessment in the moderate to severe group of AR patients were generally lower than those in the control group（all P<0.05）. Compared with the control group, the score of physical function and psychological function in mild group decreased significantly（P<0.05）. Compared with the mild group, the moderate to severe groups showed significant decreases in physical function, psychological function and material life score（P<0.05）. Conclusion:Pollen, as a airborne allergen, is the main inducement of AR in Inner Mongolia. AR can seriously affect the physical and mental health of patients and reduce the quality of life. Clinical practice should focus on providing standardized treatment interventions and good health education for AR patients to improve quality of life.

[Study on the damage of the tight junctions of nasal mucosal epithelial cells by artemisia annua pollen].

Objective: To investigate the damage and mechanism of artemisia annua pollen on tight junction of human nasal mucosa epithelial cells (HNEpC). Methods: HNEpC were cultured in vitro. Different concentrations of artemisia annua pollen (0, 20, 40, 80, 100, 160, 200 µg/ml) were used to intervene the cells for 24 h, and the cell proliferation activity was detected by the CCK-8 method. The expression and phosphorylation of p38MAPK signaling pathway were detected by Western Blot before and after the intervention of SB203580, a p38MAPK inhibitor in HNEpC. Immunofluorescence chemical staining, Western Blot and quantitative real-time PCR (qPCR) were used to observe the expression and distribution of tight junctions Occludin and Claudin-1. SPSS 21.1 software was used for statistical analysis. Results: CCK-8 results showed that, compared with the control group, the proliferation activity of HNEpC increased after 6 h intervention with different concentrations of artemisia annua pollen (all P<0.05). After 12 h of intervention, the proliferation activity of HNEpC in the 20, 40, 80, 100 and 160 µg/ml groups was not significantly changed (all P>0.05), while that in the 200 µg/ml group was decreased (P<0.05). After the intervention for 24 h, the proliferation activity of cells in the 20 and 40 µg/ml groups was not significantly changed (all P>0.05), while that in the 80, 100, 160 and 200 µg/ml groups was decreased (all P<0.05). Immunofluorescence staining showed that the Occludin and Claudin-1 proteins in the normal control group were localized on the cell membrane and expressed more and formed a ring structure around the cell membrane. However, under the intervention of high concentration artemisia annua pollen, its expression level decreased, appeared broken, fuzzy, and nonuniform distribution. Western Blot and qPCR results showed that after 24 h of intervention, the expression levels of HNEpC Claudin-1 protein and its mRNA in the pollen groups (40, 80, 100, 160, 200 µg/ml) of artemisia annua decreased compared with those of those of the control group (mRNA expression levels were 0.567±0.214, 0.443±0.109, 0.462±0.160, 0.497±0.134, 0.388±0.076 compared with 1.001±0.067, respectively, all P<0.05). However, the mRNA of Occludin protein and its mRNA only decreased in the 200 µg/ml treatment group (mRNA expression level was 0.631±0.109 compared with 1.016±0.026, P<0.05), while all the other treatment groups increased (mRNA expression levels were 1.258±0.134, 1.827±0.103, 2.429±0.077, 1.707±0.085, 1.477±0.066 compared with 1.016±0.026, respectively, all P<0.05). Western Blot showed that p-p38MAPK expression increased after intervention with 100, 160, 200 µg/ml artemisia annua pollen for 24 h. SB203580 could inhibit the decreasing expression of Occludin caused by artemisinin pollen (mRNA expression was 1.255±0.179 compared with 0.631±0.109, P<0.05), but had no effect on Claudin-1 protein expression. Conclusion: Pollen from artemisia annua may activate p38MAPK signaling pathway and destroy the close connection of HNEpC.
