Combined allergic rhinitis and asthma syndrome (CARAS) is one of the common chronic airway inflammatory diseases in children. With the development of epigenetics, research on CARAS has gradually extended from protein levels to molecular levels, such as transcription and post-transcriptional regulation. N6-methyladenosine (m6A) methylation and ferroptosis have emerged as promising research hotspots in recent years, playing crucial roles in tumors, growth and development, and allergic diseases. This paper aims to summarize the characteristics of m6A and ferroptosis, along with their roles in the onset and progression of CARAS in children, thereby providing new insights and strategies for the diagnosis and treatment of childhood CARAS.

Objective:To explore the impact of PM 2.5 concentration in Shanghai on the incidence of allergic rhinitis（AR） in the population, and provide strategies for early warning and prevention of AR. Methods:Collect daily average concentrations of atmospheric pollutants monitored in Shanghai from January 1, 2017 to December 31, 2019, and clinical data of AR patients from five hospitals in Shanghai during the same period. We used a time-series analysis additive Poisson regression model to analyze the correlation between PM 2.5 levels and outpatient attendance for AR patients. Results:During the study period, a total of 56 500 AR patients were included, and the daily average concentration of PM 2.5 was（35.28±23.07）μg/m³. There is a correlation between the concentration of PM 2.5 and the number of outpatient attendance for AR cases. There is a positive correlation between the daily average number of outpatient for AR and levels of PM 2.5 air pollution（（P<0.05）） . We found that every 10 μg/m³ increase in PM 2.5, the impact of on the number of AR visits was statistically significant on the same day, the first day behind, and the second day behind, with the strongest impact being the exposure on the same day. Every 10 μg/m³ increases in PM 2.5, the number of outpatient visits increased by 0.526% on the same day（95%CI 1.000 50-1.010 04）. Conclusion:The atmospheric PM 2.5 concentration in Shanghai is positively correlated with the number of outpatient for AR, and PM 2.5 exposure is an independent factor in the onset of AR. This provides an important theoretical basis for AR.

Exposure to traffic-related air pollutants(TRAP)has been implicated in airway allergic diseases.Recent findings include epidemiologic and mechanistic studies that shed new light on the impact of TRAP on allergic rhinitis(AR)and the biology underlying this impact.These studies have found that oxidative stress induced by TRAP could affect the axis of epithelial cell-dendritic cell-T cell towards a T-helper 2 immune response,which is the major mechanism between TRAP and AR.Further,epigenetics and microRNA might be involved in this process.Our review will summarize the most recent findings in each of these areas.

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 explore the relevance between nasal symptoms and laryngopharyngeal reflux disease in patients with allergic rhinitis. METHOD: Thirty patients of laryngopharyngeal reflux disease were diagnosed in ENT outpatient department in our hospital. All patients have symptoms of sneeze, nasal discharge as chief complaint and they responded no effect for other normal treatment for nasal-sinusitis at least three months. Orally before meals, a dose of 5 mg Mosapride citrate each time, three times a day for 7 days. Orally before meals, a dose of 20 mg Esomeprazole each time, two times a. day for 2-3 months. Nasal spray, one spray of azelastine hydrochloride once, two times a day for 2 month. RESULT: Laryngopharyngeal reflux symptom scores at four time points (the first visit, post treatment 15 days, 45 days, 75 days) were analyzed by repeated measures analysis of variance. There is a significant difference in four time points. CONCLUSION Laryngopharyngeal reflux disease has a strong association with allergic rhinitis. Patients who has allergic rhinitis nasal symptoms as chief complaint must be exclude, the laryngopharyngeal reflux disease first.

There are more than 50 000 workers in Jinchuan Group Co, Ltd (JNMC). Since all staff in JNMC are eligible for a medical examination every two years, only 23 484 nickel-exposed subjects who participated in medical examination were included in this study. Their data, collected from June 22, 2011 to September 28, 2012, in a comprehensive epidemiological survey and during medical examinations, permitted an extensive evaluation of the relation between metal exposure, gene, epigenetics and risk of human diseases. Their lifestyle investigation showed that the overall prevalence of current smokers, alcohol drinkers, and tea drinkers was 39.1%, 19.7%, and 55.2%, respectively. The prevalence of hypertension, allergic rhinitis and cholecystitis , the top 3 prevalent diseases, was 11.7%, 11.0%, and 8.9%, respectively.

OBJECTIVE: To investigate the possible effects of meteorological and environmental factors on allergic rhinitis of children. METHOD: Daily numbers of outpatients consulting general practitioners for AR between Jan 1 2007 and Dec 31 2011 were obtained from the Department of Otolaryngology-Head and Neck Surgery, Shanghai Children Medical Center. Daily maximum, average and minimum temperatures and humidity and wind power for Shanghai of the same 5 years were obtained from the Shanghai Meteorological Office. Air Quality data was provided by the Shanghai Municipal Environmental Protection Monitoring Center on daily SO2, NO2 and PM10, the average of O3 per 8 hours. The data was available as average values derived from the data of 6 state comtrolled monitoring stations distributed across Shanghai. Non-parametric generalized additive model (GAM) was used to analyze the highly non-linear or non-monotonic exposure-response relationship between meteorological and environmental factors and daily outpatient visiting for AR of children. RESULT: The daily numbers of AR children in outpatients department in this study were highest in the average daily temperature 11°C and 21°C. It showed two peak. But as the humidity increased, daily numbers of outpatients of AR children went down, indicating that the higy humidity has protective effect. Every 10 microg/m3 increase of environmental pollutants O3, SO2 and PM10 was linked to 1.95%, 1.19% and 0.33% increase in the number of visitors, respectively, suggesting the air pollution may increase the risk of onset of AR in children. CONCLUSION Meteorological and environmental factors have important effects on AR in children.

OBJECTIVE: To investigate the clinical characteristics of ocular symptoms in patients with allergic rhinitis (AR) and the impact of the ocular symptoms on patients' quality of life. METHOD: AR patients' history and clinical data were collected and analyzed. One hundred cases were extracted from adult patients with and without ocular symptoms in each group and their quality of life were evaluated using rhino-conjunctivitis quality of life questionnaire (RQLQ). RESULT: Totally 1119 cases were collected and 859 cases had ocular symptoms. Of the patients with ocular symptoms, 582 cases were mild, 234 cases were moderate, 43 cases were severe. Eye itching was the most common symptom, followed by tears, hyperemia and swelling. Patients with ocular symptoms had longer disease history than non ocular symptom group (P < 0.05). There was a positive correlation between ocular and nasal symptoms (P < 0.01); patients with ocular symptoms had more severe nasal symptoms than patients without ocular problems; while patients with moderate to severe AR had more severe ocular symptoms than mild AR patients (P < 0.01). Female patients had higher incidence (P < 0.05) and ocular symptoms score (P < 0.05) than male. Children less than 10 years old had a relative lower incidence and score of ocular symptoms. While the incidence and score had an increasing trend for patients older than fifty. There was no difference regarding the type and number of allergen in the patients with and without ocular symptom. Moreover, patients with ocular symptoms had higher scores in the domains of non-nose/eye symptoms, practical problems, ocular symptoms, emotional function and total score in RQLQ than patients without ocular symptom. CONCLUSION It was common for the AR patients to have ocular symptoms, and ocular symptoms had obvious influence on the patients' quality of life. So controlling of the ocular symptoms should not be ignored during the diagnosis and treatment of AR.

OBJECTIVE: To evaluate the relative factors influencing olfactory dysfunction in patients with chronic rhinosinusitis (CRS). METHOD: Visual analogue scale (VAS) was applied to measure the severity of olfactory dysfunction of 270 patients with CRS. Patients were divided into two groups, one was that the quality of life (QOL) of patients was affected by olfactory dysfunction (VAS > 5), the other was that without QOL affected by olfactory dysfunction (VAS ≤ 5). The association between age, gender, nasal polyps, allergic rhinitis, smoking history, early nasal surgery history and other clinical factors, and serum total IgE level, peripheral blood eosinophil count, peripheral blood mononuclear cell count and olfactory dysfunction was analyzed. RESULT: The number of patients with nasal polyps, allergic rhinitis, previous nasal surgeries, the level of serum total IgE, and the severity of edema were significantly increased in patients with impaired QOL associated with olfactory dysfunction (P < 0.05). Sex distribution, age, smoking history, deviation of nasal septum, eosinophil and mononuclear cell count did no statistically differ between the groups with and without impaired QOL associated with olfactory dysfunctions (P > 0.05). Serum total IgE increased (OR = 1.003, P < 0.01) and severe edema (OR = 2.483, P < 0.01) were the risk factors for the impairment of olfactory function, more notably for edema; whereas previous nasal surgeries was a protective factor (OR = 0.408, P < 0.01). CONCLUSION Sever edema and increased serum total IgE are risk factors, whereas previous nasal surgeries history is a protective factor for the olfactory dysfunction.
