OBJECTIVE: To investigate the epidemiological features in patients with allergic rhinitis (AR) in Yichang city, and put forward effective prevention and control measures. METHOD: Collecting the data of allergic rhinitis in city proper from 2010 to 2013, input the data into the database and used statistical analysis. RESULT: In recent years, the AR patients in this area increased year by year. The spring and the winter were the peak season of onset. The patients was constituted by young men. There was statistically significant difference between the age, the area,and the gender (P < 0.01). The history of allergy and the diseases related to the gender composition had statistical significance difference (P < 0.05). The allergens and the positive degree in gender, age structure had statistically significant difference (P < 0.01). CONCLUSION Need to conduct the healthy propaganda and education, optimizing the environment, change the bad habits, timely medical treatment, standard treatment.

OBJECTIVE: To understand the prevalence rate and the relativity of allergic rhinitis and recurring respiratory infection of preschool children in Shenzhen, and to investigate and analyse the prevalence rate, predisposing factor, allergen, therapy, turnover on allergic rhinitis and recurring respiratory infection of preschool children. METHOD: The ENT doctors examined the investigated children and recorded them, then delivered questionnaires to the children's parents and explained to them. The result was analyzed statistically. RESULT: The prevalence rate of allergic rhinitis of preschool children in Shenzhen was 20.1%, the prevalence rate of recurring respiratory infection was 13.7%, the prevalence rate (18.0%) of allergic rhinitis combined recurring respiratory infection was higher than that (7.80) of cases with non-allergic rhinitis combined recurring respiratory infection. The difference had a statistical significance (P < 0.05). CONCLUSION We initially understood the epidemiologic situation of allergic rhinitis and recurring respiratory infection of preschool children in Shenzhen, providing epidemiologic datas for the standardization of prevention and cure for allergic rhinitis.

BACKGROUND: In China, upper airway cough syndrome (UACS) is only less frequent than cough-variant asthma and accounts for 24.71% of chronic cough. This study aimed to determine the pathogenetic constituents and factors affecting UACS in children of different age groups, and to identify clinical clues for diagnosing UACS and a method for curative effect evaluation. METHODS: A total of 103 children with UACS whose chief complaint was chronic cough were studied from January to November 2013 at Children's Hospital, Capital Institute of Pediatrics. According to their age, children with UACS were divided into 3 groups: nursing children, pre-school children, and school-age children. We analyzed the differences in pathogenetic constituents and factors affecting UACS in children. The effect of UACS treatment was evaluated by the visual analog scale (VAS) and an objective examination. Chi-squared test and analysis of variance were performed with the SPSS 19.0 statistical software. RESULTS: There was a high incidence of UACS in school-age children. Rhinitis with adenoid hypertrophy was the main cause of 103 suspected UACS cases. Adenoidal hypertrophy was the major cause of UACS in the pre-school children group, while rhinitis was the major reason in the nursing children and school-age children groups. Among the 103 children, there were 45 allergen-positive children, with no significant difference among different age groups. VAS scores in the different disease groups after treatment were lower than those before treatment (all P < 0.01). VAS scores in different disease groups showed significant differences, except for 12 vs. 24 weeks after treatment (P = 0.023). Different age groups had different secondary complaints. CONCLUSIONS There are different pathogeneses in different UACS age groups. Clinical treatment efficacy of children with UACS can be evaluated by the VAS combined with an objective examination. We recommend that the course of treatment should be 12 weeks.

Objective: To explore the correlation between eosinophils (Eos) and the incidence of chronic sinusitis with nasal polyps (CRSwNP) in Xinjiang region of China by comparing the proportion of inflammatory cells in the pathological tissues and peripheral blood. Methods: Retrospective analysis was performed on 582 patients with CRSwNP who underwent endoscopic nasal surgery in the First Affiliated Hospital of Xinjiang Medical University from January 2012 to March 2018, including 367 males and 215 females, aged (45.5±13.4) years (x¯±s). Patients were divided into groups according to demographic characteristics, recurrence and complication of allergic rhinitis (AR). Preoperative blood routine and postoperative pathological section data of nasal polyps were collected to compare the ratio of inflammatory cells in pathological tissue and the ratio of peripheral blood Eos in each group. The correlation between the proportion of inflammatory cells in the pathological tissue of nasal polyps and the recurrence of CRSwNP was analyzed, as well as the distribution of (eosCRSwNP) in Uygur and Han CRSwNP patients in Xinjiang region. Statistical analysis was performed by SPSS 19.0 software. Results: Compared with non-recurrent CRSwNP patients, the ratio of Eos in nasal polyp tissue and peripheral blood was increased significantly, (Z value was -3.142 and -2.344, respectively, both P<0.05). Compared with CRSwNP patients without AR, the ratio of Eos in nasal polyps and peripheral blood was also increased significantly in patients with AR (Z value was -6.664 and -4.520, respectively, both P<0.05). There was a positive correlation between tissue Eos and CRSwNP recurrence (r=0.130, P=0.002). The majority of CRSwNP patients were both eosCRSwNP in Uygur and Han ethnic groups. Conclusions: Eos is associated with the recurrence of CRSwNP in Xinjiang region, and eosCRSwNP is the dominant factor in both Uygur and Han patients.

OBJECTIVEThe aim of this study is to investigate the self-reported prevalence and other epidemiological characteristics of allergic rhinitis from 11 cities throughout the mainland of China.

METHODSTelephone interviews were conducted in the two main municipalities (Beijing, Shanghai) and eight capital cities (Changsha, Changchun, Hangzhou, Guangzhou, Nanjing, Shenyang, Wuhan, Urumqi and Xi'an) of main provinces throughout the mainland of China after sampling target phone numbers by the approach of random digital dialing (RDD) via computer.

RESULTSIn total, the survey had sampled 684 blocks of telephone numbers in 11 cities, and dialed 119 319 telephone numbers. Of the 38 203 respondents, 4253 subjects reported allergic rhinitis, while the other 33 950 were screened negative in the telephone interviews. The self-reported prevalence of allergic rhinitis was lowest in Xi'an (8.0%), and highest in Urumqi (21.4%), with Nanjing having intermediate value (11.5%). The gender-adjusted prevalence ranged from 8.5% in Xi'an to 21.3% in Urumqi, while the age-adjusted prevalence of self-reported allergic rhinitis ranged from 8.7% in Beijing to 24.1% in Urumqi.

CONCLUSIONSThe study demonstrates that the self-reported prevalence of allergic rhinitis in 11 cities throughout the mainland of China has wide variations, and the strategy of prevention for allergic rhinitis should be conducted according to the epidemic features of it.
