OBJECTIVE To investigate the expression profile of inflammation related genes in laryngeal squamous cell carcinoma by functional gene chip technique and to probe into the role of correlative genes in pathogenesis of the laryngeal squamous cell cancer and in tumor immunity. METHODS The total RNAs were respectively extracted from two pair samples of laryngeal tumor and the normal tissue around the tumor, and then were reversely transcribed to cDNAs, then synthesized to cRNAs. The cRNAs were labeled with the hybridization probes. The probes were then hybridized with four pieces of inflammation related genes chip. It was chemiluminescently detected and the acquired image was analyzed with special software. RESULTS Forty genes were differently expressed in inflammation related gene profile of laryngeal tumor, among which 22 genes were upregulated and 18 genes were down regulated. Thirteen genes were shown differential expression in both chips with 10 upregulated genes and 3 downregulated genes. CONCLUSION The differently expressed genes in inflammation related gene chips will provide clues and theoretical foundation for the investigation of the relationship between tumor and inflammation, and also the immune pathogenesis of laryngeal tumor. Furthermore CCL-7 may have an important role in the occurrence of laryngeal cancer, and the role of immunity of the pathogenesis of laryngeal tumor needs further studied.

OBJECTIVE To investigate the expression of SleX and CD24 in nasal inverted papilloma and its pathologic features.METHODS HE staining were conducted to study the pathologic features in specimens of 11 cases with nasal inverted papilloma. Further,immunohistochemistry stain for SleX and CD24 were performed in total specimens.RESULTS One case(9.1%) was diagnosed as severe atypical hyperplasia but tumor cells did not invaded basal membranes.SleX staining located at cell membranes. Positive SleX staining was found in 9 specimens (81.8%) and 1 normal nasal epithelium (16.7%).CD24 staining located in cytoplasm.Positive CD24 staining was found in 8 specimens of nasal inverted papilloma (72.7%). CD24 was negative in nasal epithelial cells and only a few lymphocytes were positive.CONCLUSION Some cases of nasal inverted papilloma are diagnosed with severe atypical hyperplasia.Most of cases express CD24,so nasal inverted papilloma may be a borderline tumor.Expression of SleX and infiltration of inflammatory cells suggest that nasal inverted papilloma may be related to inflammatory reactions.

OBJECTIVE: To construct a kind of recombinant plasmid PGCsi-AQP1 delivery with DOPC and explore the inhibit effect of laryngeal carcinoma by RNAi targeting AQP1 in vivo. METHOD: Male BALB/c mice, 6 weeks of age transplanted with laryngeal carcinoma cell line Hep-2, four groups were divided randomly: Tail vein injection group (TVIG), Carcinoma around injection group (CAIG), negative control group (NCG) and blank control group (BCG). The recombinant plasmid PGCsi-AQP1 delivery with DOPC were inject into tail vein or surrounding tumor. HE pathological slides and tumor size were observed and inhibitory rate was figured up. The level of AQP1 protein expression and high microvessel density were detected by Immunohistochemical staining (IHC). RESULT: We constructed BALB/c mice models of laryngeal carcinoma successfully (1) HE staining: cell putrescence, nuclear pyknosis and apoptotic bodies were more in the tumor tissues of experimental groups than two control groups. (2) The total volumes of tumor in experimental group were both smaller than in two control groups (P < 0.01). The inhibition rate of TVIG and CAIG were 52.4% and 53.5% respectively and there was no significant difference (P > 0.05). (3) IHC: the AQP1 positive cells and microvessel density in TVIG and CAIG were both less than in two control groups (P < 0.01). CONCLUSION Neutral lipsomes DOPC could help carriaging the recombinant plasmid PGCsi-AQP1 to tumor and then play an inhibit role in laryngeal carcinoma tissue by RNAi targeting AQP1 in vivo.

OBJECTIVE: To investigate whether the allergic factors impact the severity of chronic rhinosinusitis or not, further more, to explore the relationship between allergic rhinitis and chronic rhinosinusitis. METHOD: A retrospective review was done on 103 patients. All of these patients were under functional intranasal endoscopic sinus surgery after expectant treatment is ineffective. We devided the patients into different groups according to the result of skin prick and specific IgE and if there is difference in VAS score, Lund and Kennedy endoscopic score, Lund-Mackay CT score between the groups. We also analysed the symptoms in different chronic rhinosinusitis patients allerged to variant kinds of allergen. The SPSS 17.0 software was used to analyze the data. Statistical analysis was performed by t-test, rank order test or χ2 test. RESULT: The duration of the disease, VAS score of nasal blockage, score of Lund-Mackay CT and Lund and Kennedy endoscopic before the operation were in no statistical sense after when compared with the two groups of patients with chronic rhiriosinusitis who grouped according the result of skin prick and specific IgE. The VAS score of facial pressure and loss of smell was higher in patients with chronic rhinosinusitis which the skin prick and specific IgE were positive. The VAS score of nasal discharge was higher in patients with chronic rhinosinusitis who got negative skin prick and specific IgE result. The symptoms of chronic rhinosinusitis improved with operation no matter the group of skin prick and specific IgE positive or negative and VAS score of nasal blockage improved significantly in negative group. The symptoms of sneezing, rhinorrhoea and rhinocnesmus improved after operation among the chronic rhinosinusitis patients with skin prick and specific IgE. The number of cockroach allergy is larger among the patients with chronic rhinosinusitis without polyps than the one among the patients with chronic rhinosinusitis with polyps. CONCLUSION Allergic factor didn't impact much the severity of chronic rhinosinusitis patients who were failed in expectant treatment, besidesthe postoperative outcomes showed that only influence the severity of nasal discharge, facial pressure and loss of smell. Different kinds of allergen were found between the patients of chronic rhinosinusitis with or without polyps. No significantly functional endoscopic sinusitis sugrery outcome were related to the allergic factor. But the allergic factor may interfere the remission of nasal discharge after surgery.
