OBJECTIVE To study the significance by analyzing the expression of human protection of telomeres1(POT1)and telomeric repeatbinding factor-2(TRF2)in the tissues of laryngneal squamous cell carcinoma(LSCC)and in polyp of vocal cord tissues. METHODS The expression of POT1 and TRF2 in 20 tumor samples and 19 polyp of vocal cord were determined by the indirect immunofluorescence method. The results were scored and analyzed statistically. RESULTS The positive expression rates of POT1 and TRF2 in tumor samples was 65.00% and 70.00% respectively. There were no positive expression of POT1 and TRF2 in polyp of vocal cord. The positive expression of POT1 was higher in poorly differentiated laryngeal carcinoma than that in well-differentiated and moderately differentiated laryngeal carcinoma(Chi-square test with contingency table, P0.05). CONCLUSION The expression of POT1 and TRF2 in laryngneal squamous cell carcinoma were remarkable, POT1 and TRF2 may play a critical role in tumorigenesis of laryngneal squamous cell carcinoma. There was statistical significant difference for degrees of POT1 expression in different tumor histological grades.

Objective:To explore the expression and clinical significance of late autophagy in per-ipheral blood mononuclear cells (PBMCs) of patients with primary gouty arthritis (GA).Methods:Peripheral blood, clinical data, and laboratory tests were collected from 30 patients with acute gout (AG), 30 patients with intermittent gout (IG), and 50 healthy controls (HC). Quantitative polymerase chain reaction (RT-qPCR) was used to detect mRNA expression levels of autophagy-related genes (ATG5, ATG12, ATG16, ATG3, ATG7, ATG10, ATG4B, LC3-2/LC3B). Measurement data conformed to normal distribution were tested using t test or analysis of variance (ANOVA), and non-normal distribution data were tested using Mann-Whitney test or Kruskal-Wallis H test. SNK was used for pairwise comparison among the three groups. Correlation between variables was tested by Spearman correlation analysis. Results:① The expression level of ATG5 mRNA,ATG12 mRNA, ATG16 mRNA, ATG10 mRNA and LC3-2 mRNA in the AG group was lower than that of the IG group and the HC group, and the expression level of the IG group was lower than that of the HC group[9.16×10 -3(6.04×10 -3, 15.00×10 -3) vs 14.48×10 -3(9.95×10 -3, 21.38×10 -3) vs 0.08×10 -3(12.21×10 -3, 42.79×10 -3), H=19.377, P<0.001; 18.89×10 -3(13.85×10 -3, 24.92×10 -3) vs 21.13×10 -3(12.11×10 -3, 28.06×10 -3) vs 33.57×10 -3(13.11×10 -3, 49.89×10 -3), H=7.545, P=0.023; 8.72×10 -3(4.96×10 -3, 13.74×10 -3) vs 10.62×10 -3(7.48×10 -3, 24.71×10 -3) vs 20.07×10 -3(11.99×10 -3, 39.56×10 -3), H=20.962, P<0.001; 1.05×10 -3(0.73×10 -3, 1.84×10 -3) vs 1.60×10 -3(0.93×10 -3, 2.58×10 -3) vs 1.69×10 -3(1.05×10 -3, 3.54×10 -3), H=8.193, P=0.017; 2.31×10 -3(1.22×10 -3, 3.53×10 -3) vs 2.78×10 -3(1.68×10 -3, 5.96×10 -3) vs 3.68×10 -3(2.00×10 -3, 5.67×10 -3) , H=7.135, P=0.028]. The expression level of ATG4B mRNA in the AG and IG group was higher than that in HC group, and there was significant difference between IG group and AG group, IG group and HC group[9.95×10 -3(6.32×10 -3, 12.23×10 -3) vs 10.86×10 -3 (8.80×10 -3, 17.03×10 -3) vs 8.07×10 -3(5.52×10 -3, 11.63×10 -3), H=8.531, P=0.014]. There was no significant difference between the ATG3 mRNA and ATG7 mRNA groups ( H=0.539, 3.739, bothall P values >0.05). ② The results of Spearman correlation analysis suggested that in patients with acute gout, ATG3 was negatively correlated with PDW and MPV ( r=-0.499, P=0.006; r=-0.463, P=0.011); ATG4B was positively correlated with HDL-C ( r=0.408, P=0.048); ATG7 was negatively correlated with GLOB ( r=-0.554, P=0.001); ATG10 was positively correlated with ALB ( r=0.412, P=0.024) and negatively correlated with Crea and hsCRP ( r=-0.459, P=0.011; r=-0.375, P=0.045); ATG12 was negatively correlated with MO ( r=-0.434, P=0.017); ATG16 was negatively correlated with ALT and AST ( r=-0.389, P=0.034; r=-0.366, P=0.047); LC3-2 was positively correlated with UA ( r=0.381, P=0.041) and negatively correlated with MPV and PDW ( r=-0.413, P=0.026; r=-0.449, P=0.015). In patients with intermittent gout, ATG3 and ATG4B were negatively correlated with apoB100 ( r=-0.555, P=0.011; r=-0.462, P=0.040); ATG5 was negatively correlated with Crea ( r=-0.456, P=0.011); ATG10 was negatively correlated with TC, LDL-C, and apoB100 ( r=-0.526, P=0.017; r=-0.556, P=0.011; r=-0.515, P=0.020). Conclusion:Autophagy is involved in the development of gout, and is correlated with ibflammatory and metabolic indicators, suggesting that autophagy is an important feature in the pathogenesis of GA.

Objective: Surfactant protein A (SP-A) is protein that appears to play an important role in mammalian first-line host defense. The objective of this study was to immunolocalize SP-A in human sinonasal tissue. Method:Eleven cases of allergic rhinitis, fifteen cases of polyp and seven cases of normal middle turbinate were studied with immunohistochemistry and immunofluorescence method to detect the expression of SP-A. Result:The expression of SP-A in allergic rhinitis and polyp were dramatically higher than that in controls(P<0.05), and there was no remarkable difference in the expression of SP-A between allergic rhinitis and polyp(P>0.05). The result demonstrated that SP-A was positivly correlated with eosinophils within the basement membrane of epitheli-um(R=0.81,0.55). In the result of immunofluorescence, there was significantly higher expression SP-A in nasal mucosa of allergic rhinitis and nasal polyp than that in control group(P<0.05). Conclusion:SP-A is likely to play key roles in the inflammatory reaction process of allergic rhinitis and polyp. Its secretion in the upper airway indicates that future studies may allow manipulation of this protein and development of novel treatments for sinonasal pathology.

OBJECTIVE:
To investigate the positive rates of some allergens in different age groups of allergic rhinitis patients, and to analyze the relationship between serum specific immunoglobulin E(sIgE) and total immunoglobulin E(IgE).
METHOD:
Six hundred and fifty-three patients with allergic rhinitis, tested by AllergyScreen system, were enrolled in our research.
RESULT:
The positive rate of sIgE in all patients was 85.5%. The positive rate of dust mite was the highest with the result of 76.3%, and the positive rate of feline or dogs hair was the lowest of 20.3%. The statistical significance of different positive rate of some allergens were found in the different age groups. All the patients were divided into two groups, one was younger than 18 years old group, which including 18 years old and another was older than 18 years old group. Except Mx, the positive rate of other allergens existed statistical difference. The level of serum total IgE could not reflect the positive rate of sIgE completely.
CONCLUSION
It is an effective and reliable method of the diagnosis of allergic rhinitis to combine the analysis of total serum IgE and sIgE levels with patients clinical manifestations. Different strategies should be employed for the prevention and treatment of allergic rhinitis according to their ages.

OBJECTIVE:
To study the expression of Eotaxin and Eotaxin-2 in nasal polyposis and nasal polyp and explore the different mechanism between polyposis and polyp.
METHOD:
Fifteen cases of nasal polyposis, thirteen cases of polyp and eight cases of normal middle turbinate were studied with immunohistochemical SP method to detect the expression of Eotaxin and Eotaxin-2.
RESULT:
There were significant differences between either two groups about the expression of Eotaxin-2 (P < 0.05). The expression of Eotaxin in nasal polyposis and polyp were dramatically higher than in controls (P < 0.05), the expression of Eotaxin between nasal polyposis and polyp was no remarkable difference (P > 0.05).
CONCLUSION
Both of Eotaxin and Eotaxin-2 likely play key roles in the inflammatory reaction process of nasal polyposis and polyp. The different expression of Eotaxin-2 between nasal polyposis and polyp demonstrates it may be one of the main causes in the different mechanism of the two diseases.

OBJECTIVE:
To establish the rat model of depression and observe its morphological changes and nerve growth factor (NGF) expression in nasal mucosal.
METHOD:
Thirty SD rats were divided into depression model group and normal controls with 15 rats in each group. The rat depression model were made by application of chronic unforeseeable medium stress stimulating. Behavior change were observed with open box experiment(open field) and humoral consumption-experiments (sucrose consumption), After being sacrificed, the nasal mucosal were taken for HE and NGF immunohistochemical study. The difference of nasal mucosal NGF protein between two groups were examined with medical digital image analysis technology.
RESULT:
There were no swelling and inflammatory cells infiltrating in nasal mucosal of normal group, but 53% nasal mucosal of depression model were observed such morphological changes. Th NGF immunohistochemical staining were negative in normal group but positive in 53% depression model group. There were significant differences between two groups (P < 0.01).
CONCLUSION
Depression rats may appear rhinitis symptoms under long-term stress stimulating. NGF may exert immunoregulatory effects, stimulate the immune cell proliferation and gathering, induce various media release, increase the sensitivity of nerve fibers itself and the producing of neuropeptide, promote the formation of nerve source inflammation and increase the reactivity of nasal mucosa.
