Different Surgical Treatment of Chronic Rhinitis-sinusitis the Impact on Maxillary Sinus Mucociliary Transport Function / 现代生物医学进展

Objective:To compare the effects of different surgical treatment of chronic rhinitis-sinusitis difference,and its impact on transport function of maxillary sinus mucociliary,provide a clinical-surgical sinusitis preferably reference about the treatment of chronic nasal formulation for.Methods:From 2013.9-2014.12,otorhinolaryngology clinic in our hospital,160 cases were diagnosed as chronic nose-as research subjects were randomly divided into four groups of patients with sinusitis were treated from 1 to 4,60 cases in each group;treatment groupl receiving the maxillary sinus ostium augmentation,treatment group 2 received fenestration,treatment group 3 through tears crypt before maxillary sinus surgery,treatment 4 group receiving the maxillary sinus balloon dilatation;after covering the nasal mucosa observed and compared four groups of patients about edema,vesicle formation,bone exposure,scarring,etc.,as well as internal maxillary sinus secretions traits,volume situation,and compared patients after four groups line maxillary sinus cavity and perioral saccharin test biopsy cases three months and six months.Results:The four groups were made after surgery better clinical efficacy,and group efficacy 4 with the other three groups,the effect is most significant (all P ＜0.05),the difference was statistically significant,and after three months and six months,group 4 compared with other surgical group,the Lund-Kernedy score were also lower,MMT time were also lower,the difference was more significant (all P ＜0.05);in the maxillary sinus biopsy aspects:the number of postoperative inflammatory cells and dendritic cells and glandular cell morphology and submucosal edema improved submucosal structures also in the group of four most significant (P＜0.05).Conclusion:Maxillary sinus balloon dilatation treatment chronic nasal sinusitis curative effect is higher,which can effectively improve the cell and submucosal gland cell morphology and sinus mucosa edema,sinus unobstructed drainage effect,and high safety.

Distinct Inflammatory Profiles in Atopic and Nonatopic Patients With Chronic Rhinosinustis Accompanied by Nasal Polyps in Western China

PURPOSE: The role of systemic sensitization in the pathophysiology of chronic rhinosinusitis with nasal polyps (CRSwNP) remains elusive. This study sought to characterize the pattern of cytokines in polyp tissues from atopic and nonatopic patients with CRSwNP. METHODS: Atopic and nonatopic polyp and normal tissues were collected from 70 CRSwNP patients and 26 control subjects, respectively. The distribution of inflammatory cells (eosinophils, neutrophils, mast cells, etc.) were examined using immunohistochemistry, the mRNA levels of the transcription factors GATA-3, T-bet, RORc, and FOXP3 were determined using quantitative real-time polymerase chain reaction. The levels of inflammatory mediators (IFN-gamma, IL-5, IL-17A, etc.) in tissue homogenates were measured using enzyme-linked immunosorbent assay (ELISA). Moreover, the levels of inflammatory mediators in the supernatant of anti-IgE stimulated polyp tissues were measured using ELISA. RESULTS: Atopic CRSwNP patients were characterized by increased eosinophil accumulation, enhanced eosinophilic inflammation (elevated IL-5, ECP, and total IgE), and significantly increased GATA-3 mRNA levels (P<0.05), whereas both atopic and non-atopic CRSwNP patients showed decreased FOXP3 mRNA expression (P<0.05). After addition of anti-IgE stimulation, atopic CRSwNP patients produced more IL-5, IL-2, IL-10, IL-17A, and PGD2 in the supernatant of stimulated polyp tissues than nonatopic CRSwNP patients did. CONCLUSIONS: Atopic and nonatopic CRSwNP patients may possess the patterns of inflammatory response in polyp tissues.

The expression and significance of interleukin-17 and the infiltrating eosinophils in nasal polyps and nasal mucous of allergic rhinitis / 临床耳鼻咽喉头颈外科杂志

Objective:To observe the expression of interleukin-17 and the infiltration of eosinophilic cells in nasal polyps and allergic rhinitis, and investigate the roles of IL-17 and eosinophils in the etiology of nasal polyps and allergic rhinitis.Method:A study was conducted on 21 patients of nasal polyps, 18 ones of allergic rhinitis and 12 normal individuals. Immunohistochemical stain with the rabbit monoclonal antibodies of IL-17 was carried out.The eosinophilic cells infiltrated in different tissues were stained with HE, then counted under high power filed.The data was analyzed with ANOVA of SPSS12.0 software.Result:Many IL-17 stained cells were found in the samples of nasal polyps and allergic rhinitis, which were significantly higher than those in normal individuals(P<0.05). Positive cell number in tissues of allergic rhinitis was similar to that in nasal polyps, but higher than in normal individuals. As for HE staining, there was no significant deviation of numbers of eosinophilic cell in tissue between allergic rhinitis and nasal polyps,while which differed from the normal ones(P<0.05).Conclusions:①IL-17 is a newly cytokine which expressed in mucosa of allergic rhinitis and nasal polyps tissue. It indicates the degree of immunological reaction and inflammatory reaction, and can be used as an index to research the mechanism of nasal polyps as well as allergic rhinitis.②The eosinophilic cells count was correlated with the amount of IL-17 positive cells in nasal ployps and with allergic rhinitis correlation coefficients were R=0.606(P<0.01)and R=0.446(P<0.05) respectively . It seems that eosinophils, which are regulated by IL-17, play an important roles in the development of nasal polyps and allergic rhinitis.

IL-17 is a newly cytokine which expressed in mucosa of allergic rhinitis and nasal polyps tissue. It indicates the degree of immunological reaction and inflammatory reaction, and can be used as an index to research the mechanism of nasal polyps as well as allergic rhinitis. 2. The eosinophilic cells count was correlated with the amount of IL-17 positive cells in nasal polyps and with allergic rhinitis correlation coefficients were R = 0. 606 (P < 0 01)and R = 0.446 (P < 0.05) respectively.
