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.

Avian influenza virus H6N1 subtype has been circulating in aquatic bird and terrestrial bird,and is the most frequently detected subtype of influenza A virus in those hosts.Genetic analysis results suggested that this virus might be the progenitor of the highly pathogenic avian influenza H5N1 virus,as seven of eight gene segments of those viruses had a common source.As continuing evolution of H6N1,it could spread across species barriers to mammals and had strong infection ability in mice,swine and ferrets.Serological epidemiological survey showed that a few people were positive for H6 avian influenza virus antibody and then the world's first human infection with influenza virus H6N1 subtype was reported in May 2013.Therefore,with the expansion of the host range of the virus,gene mutation and gene reassortment of H6N1 virus can occur in these hosts,and then it may evolve into novel variant strain with infected human potential.

Objective To observe the effects of the Ossatron high-energy shock waves on bone nonunion and delayed union.Methods Between October 2004 and October 2005,18 patients with nonunion and four patients with delayed union were treated with high-energy extracorporeal shock wave therapy(Ossatron,HMT Co., Swiss).Facture lines were located with C-arm X-ray before treatment.Parameters of shock waves were decided according to fracture sites.Patients with unstable fixation received plaster or bracing for 6 to 8 weeks after treatment. After therapy,follow-up radiography was performed at 6 and 12 weeks and monthly afterwards until the fracture united. Results The mean follow-up was 6.7 months(range,3 to 12 months).There were no complications except local petechial hemorrhage and local swelling in 10 patients.Thirteen patients(59.1%)got bony union,including 12 patients(66.7% )with stable internal fixation,and the average healing time was 4.3 months(range,6 weeks to 6 months).Nine fractures(40.9%)still suffered nonunion.Conclusion High-energy shock waves are a good alternative therapy for nonunion and delayed union,with obvious advantages of being non-invasive and safe.
