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.

OBJECTIVETo explore the health-related quality of life (QOL) status of patients with chronic rhinosinusitis and nasal polyps.

METHODSOne hundred and twenty patients with chronic rhinosinusitis and nasal polyps and two hundred individuals passing health examination were enrolled by random and their QOL scores were assessed by using QOL instruments including existing SF-36 questionnaire (Chinese version ) and SNOT-20 questionnaire translated into Chinese, of which clinimetric and psychometric properties were tested.

RESULTSThe feasibility, reliability, validity, and responsibility of Chinese version of SNOT-20 questionnaire all passed the test. By the assessment of SF-36 questionnaire, it revealed that scores of six domains such as physical functioning, role physical, bodily pain, mental health, vitality, and general health from patients with chronic rhinosinusitis and nasal polyps were lower than that of control group except social functioning and role emotional (P < 0.05). It showed by Chinese version of SNOT-20 questionnaire that patients exceeded healthy individuals in the scores of twenty items of three domains including physical problems, functional limitations, and emotional consequences, of which the most five important items affecting health status were respectively need to blow nose, thick nasal discharge, lack of a good night's sleep, dizziness, and post-nasal discharge (P < 0.05).

CONCLUSIONSQOL instruments such as Chinese version of SF-36 and SNOT-20 questionnaires can effectively differentiate the QOL status between patients with chronic rhinosinusitis and nasal polyps and healthy individuals. The negative impact of chronic rhinosinusitis and nasal polyps on patients' QOL includes physical functioning, role physical, bodily pain, mental health, vitality, general health, and emotional consequences. The problems of nasal discharge, sleep, and dizziness should be sufficiently emphasized in clinical treatment.

OBJECTIVEThe purpose of this article is to establish an endoscopic score system for quantitative evaluation of the inflammation of mucous membrane in patients with chronic rhinosinusitis (CRS) , and to investigate the correlation of this system with a variety of clinical factors.

METHODSA set of score system was constructed based on anatomic configuration, status of mucous membrane and nasal secretion to evaluate quantificationally the severity of inflammation of CRS. The clinical correlation of this system was studied prospectively in 60 CRS patients, with a variety of clinical factors which included age, duration of disease, previous recurrence and the years from recent recurrence, atopy, serum total immunoglobulin E (TIgE), serum eosinophil cationic protein (ECP), the count of blood eosinophil, the count of tissue inflammatory cell, the extension of CRS indicated by CT, smoking, concomitant chronic inflammation in lower respiratory tract. All above factors were analyzed statistically with the endoscopic score by Pearson correlation and multi-factor linear regression analysis.

RESULTSIn pearson analysis, the correlative factors with the evaluated score included age (x1, r = - 0.310, P = 0.016), the extension of disease (x2, r = 0. 810, P < 0.0005), recurrence (x3, r = 0.408, P = 0.001), eosinophil of nasal tissue (x4, r = 0.279, P = 0. 031), duration of disease (x5, r = 0.536, P < 0.0005), concurrent nasal polyps (r = 0.549, P < 0.0005), plasm cell (r = 0. 317, P = 0.014) and years from the recent recurrence (r = 0.385, P = 0.002). In multi-factor linear regression, the five independent predictive factors were recurrence, age, extension of disease, tissue eosinophils, years of disease. The regressive equation is y = 10.148 - 0.152 (x1) + 2.250 (x2) + 3.348 (x3) + 1.233 (x4) + 0.270 (x5).

CONCLUSIONSAppropriate score system by nasal endoscopy is feasible to evaluate quantificationally the degree of inflammation of CRS; being appropriately modified, it is even able to reveal the underlying histological behavior finely.

OBJECTIVETo investigate the genetic mode of nasal polyp and the effect of genetic factor on occurrence of the disease.

METHODSA genetic epidemiological case-control study including 280 pedigrees (120 nasal polyp cases and 160 controls) was conducted. The segregation ratio and the heritability of nasal polyp were respectively estimated by the Li-Mantel-Gart method and the Falconer method.

RESULTSThe segregation ratio was 0.124 (95% CI 0.081-0.167), significantly lower than 0.25, which showed that nasal polyp did not possess the characteristics of monogenetic model. The prevalence rate of first-degree and second-degree relatives in cases were 8.571% and 3.086% respectively, which were significantly different (X2 = 24.851, P < 0.01) and were higher than that noticed 1.376% and 1.141% in controls (X2 = 33.547 and 14.274, all P < 0.01). The heritability of the first-degree and second-degree relatives of nasal polyp was 64.488% and 61.947%. Among the first-degree relatives of nasal polyp probands, the heritability of the adult group and the children group were respectively 60.735% and 74.598% (the difference was significant, X2 = 4.504, P < 0.05). The heritability of the first-occurred group was 62.839% and the recurred group was 74.304% (the difference was significant, X2 = 4.105, P < 0.05).

CONCLUSIONSThis study indicated that the genetic model of nasal polyp belonged to polygenetic and the genetic factors played an important role in the occurrence of nasal polyp, especially for young or recurred patients.

OBJECTIVETo explore the clinical effect and the influence factors after endoscopic surgery for chronic sinusitis.

METHODSThe clinical data of 337 patients with chronic sinusitis treated by endoscopic surgery were analyzed, including gender, age, culture level, course of the disease, the days of hospitalization, medical history, smoking, drinking, early surgery history, allergic rhinitis (AR) history, clinical classification, visual analogue scale (VAS) score, nasal endoscopy score, nasal polyps, CT examination score, side, nasal adhesion and postoperative follow-up compliance. The clinical effect of endoscopic sinus surgery was evaluated 6 months after operation according to the 1997 Haikou standard. SPSS 18.0 software and conducted chi-square test and logistic regression analysis were used to analyze the data.

RESULTSThree hundred and thirty-seven chronic sinusitis patients were followed up after endoscopic surgery. It was found that 298 cases (88.4%) cured, 29 cases (8.6%) improved, 10 cases (3.0%) invalid. The clinical curative effect of the patients with chronic rhinosinusitis without nasal polyp was better than that of the patients with chronic rhinosinusitis with nasal polyp, the difference was statistically significant (χ(2) = 10.932, P < 0.01). After many factors Logistic regression analysis, the most important effect factor in the clinical curative effect were clinical type, AR or not, VAS score, nasal endoscopic examination score, CT examination score, multiple nasal polyp or not, postoperative nasal adhesion or not and postoperative follow-up compliance.

CONCLUSIONThe clinical effective of endoscopic sinus surgery is influenced by not only surgery itself, but also by clinical classification, whether and not with AR and so on.

OBJECTIVETo replicate the polymorphisms in risk genes of chronic rhinosinusitis in a Chinese Han population.

METHODSEnrolled in this study were CRS patients with nasal polyps (n = 306, CRSwNP), CRS patients without nasal polyps (n = 332, CRSsNP), and controls (n = 315) in a Chinese population. All the patients were recruited from clinic of the department of Otorhinolaryngology of Beijing Tongren Hospital between 2008 February and 2009 July. A total of 10 single nucleotide polymorphisms (SNPs) selected from previous identified SNPs associated with CRS in Canadian population were individually genotyped. Allele and genotype frequencies were calculated by frequency counting, the chi-square test or exact method were applied to analyze the results.Final results were corrected by Bonferroni multiple correction.SPSS 13.0 software was used for statistical analysis.

RESULTSOne SNP in AOAH gene(rs4504543, P = 1.95 × 10⁻⁵, OR = 0.559 0) was identified to be significantly associated with whole CRS cohort. After subgroup analysis for the presence of nasal polyps (CRSwNP and CRSsNP), the same SNP in AOAH (rs4504543, P = 3.47 × 10⁻¹², OR = 0.284 8) was also found to be significantly associated with CRSsNP cohorts.

CONCLUSIONSAOAH was significantly associated with CRS and its polymorphisms might play a role in the susceptibility to develop CRS in Chinese population.

OBJECTIVE: To investigate the correlation of allergic rhinitis and chronic rhinosinusitis with nasal polyps in the Ningxia region. METHOD: One hundred and sixteen patients diagnosed with allergic rhinitis, chronic rhinosinusitis with nasal polyps, allergic rhinitis combined with chronic rhinosinusitis with nasal polyps in the department of Otorhinolaryngology Head and Neck Surgery, Ningxia Medical University Hospital from 2009 January to December was analysed in this study, followed by grouping the experimental group I: allergic rhinitis(AR) group (46 cases), the experimental group II: chronic rhinosinusitis with nasal polyps group (46 cases), the experimental group III: allergic rhinitis combined with chronic rhinosinusitis with nasal polyps group (24 cases), and the normal control group (31 cases). The skin prick test was used and the serum specific IgE concentration of selected objects was measured by enzyme linked immunosorbent assay. RESULT: (1) The positive rate of specific IgE in the experimental group I was 83.3%, the concentrated for specific IgE mainly graded in 0 to 3 level, The total positive rate of specific IgE in the experimental group II and III were 75.0% and 87.5%. (2) The specific IgE concentration in the experimental group I, II , III and control group were 10.33 +/- 2.12 (kU/L), 8.43 +/- 2.23 (kU/L), 5.28 +/- 2.16 (kU/L), 1.03 +/- 3.96 (kU/L), respectively. The data analyzed using ANOVA showed that the specific IgE concentration in the experimental group I, II, III compared with the control group was significantly different; CONCLUSION (1) The specific IgE concentration in the Ningxia region of allergic rhinitis, chronic rhinosinusitis with nasal polyps were graded in 0 to 3 level, mainly graded in 1 level and lower than other regions. The positive rates of the skin prick test about Wormwood, German cockroach, house dust mites and pollen IV allergen were relatively higher in Ningxia region. (2) The specific IgE concentration was relatively higher in the allergic rhinitis patients combined with chronic rhinosinusitis with nasal polyps. Allergic rhinitis may promote the development of chronic rhinosinusitis with nasal polyps.

OBJECTIVETo investigate the incidence and severity of pulmonary function impairment in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).

METHODSIn this prospective study, fifty-six patients with bilateral CRSwNP who were scheduled for functional endoscopic sinus surgery during a period from March to June 2010 in the Department of Otolaryngology of Qilu Hospital, were recruited in this study. Routine medical and rhinological examinations such as nasal endoscopy, sinus CT scan, and skin prick tests (SPT) for common inhalant and food allergens, and cytological examination of the paraffin-embedded NP tissues were performed together with a full assessment of the pulmonary functions.

RESULTSBased on the pulmonary function tests, the rate of patients showing bronchial hyperresponsiveness (BHR), asthma, and abnormal pulmonery functions were 37.5%, 44.6%, and 53.6%. In patients who did not have a history of lower airway symptoms, the rate of abnormal pulmonary functions was 50.0%, the rate of BHR was 43.2%. There was an increased rate of BHR, asthma and abnormal pulmonary functions in patients with a higher polyp grading score or Lund Mackay CT scan score (polyp grading score: χ(2) were 8.077, 3.989 and 7.445, P < 0.01 or < 0.05. CT scan score: χ(2) were 3.863, 5.380 and 4.309; 4.293, 4.293 and 4.572; 10.572, 13.504 and 13.295, P < 0.01 or < 0.05). The rate of BHR and asthma in patients with positive SPT were higher (P < 0.05). In patients with eosinophils hyperplasia in nasal polyps, the rate of BHR, asthma and abnormal pulmonary functions were higher (χ(2) were 4.065, 5.217 and 3.376, P < 0.05 or P < 0.01).

CONCLUSIONSThere is a high risk of developing lower airway diseases in patients with CRSwNP.
