Objective To research the chronic respiratory infectious diseases caused by Pseudomonas aeruginosa need to objectively the reflection of the real environment in the body, so established a mouse model of chronic pulmonary infection with Pseudomonas aeruginosa and analyzed it's inflammatory response. Methods Establishment of chronic bronchial infection mice model that were inoculated with Pseudomonos aeruginosa-laden agarose beads, and analyzed its inflammatory response by detected the cytokines and MMP-2, and a differential cell count and a total leukocytes count were performed as well. Results Pseudomonas aeruginosa had been detected after infection, and there were changes in pathological. Pulmonary inflammation appeared in 1 d and reached near baseline levels by 7 d after inoculation. It was verified that the peak of inflammatory reaction in Pseudomonas aeruginosa infection is in 2-3 d; the mice did have detectable levels of circulating matrix metalloproteinase-2 ( MMP-2 ) after infection with Pseudomonas aeruginosa. MMP-2 concentrations in the blood serum peaked at 3 d after inoculation. It is indicated that Pseudomonas aeruginosa can initiate a certain degree of pulmonary fibrosis on the basis of the pulmonary inflammation. Conclusion In this study, chronic bronchial infection animal model affected by Pseudomonas aeruginosa was established successfully. Base on this animal model, we can do the pathogenicity and drug resistance of Pseudomonas aeruginosa further study.

The spike (S) and nucleocapsid (N) proteins, which are responsible for viral binding to cell surface receptors and the formation of ribonucleoprotein complexes during virion assembling, are major structure proteins of severe acute respiratory syndrome coronavirus (SARS-CoV). The expression of recombinant protein may give more accurate result for detecting SARS-CoV infection. A novel fusion protein,comprising of two fragments of N and S proteins from SARS-CoV, was prepared. Our computer-assisted analysis suggested that the immunodominant domains were located in the amino acid residues 1-227 of N protein and 450-650 of S protein, further the fusion of the two fragments did not change the immunochemical characteristics. The complementary DNA(cDNA) encoding N1-227 fused with S450-650 was obtained by sequence overlapping extension (SOE), and named NLS. It was cloned into pET-28a ( + ), an expression vector for His-tag fusion protein. This new constructed fusion protein was prokaryotic expressed in E. coli,and purified by metal chelate affinity chromatography with the purity over 95 %. The purified fusion protein was identified by anti-His monoclonal antibody and convalescence SARS patients serum. The NLS protein based ELISA showed that NLS maintained appropriate antigenicity and specificity to react with the sera of convalescent SARS patients. The functional NLS protein were successfully expressed and purified. And the fusion protein based ELISA can be used for detection of antibodies (Abs) against the S and N proteins of SARS-CoV. It may provided a novel diagnostic tool and have the potential application in developing of anti-SARS vaccine.

Objective:To assess the guidance of 3D reconstruction in the surgical and orthodontic management of maxillary palatal impacted canines with cone-beam computed tomography (CBCT).Methods:22 adolescent patients with 26 impacted maxillary conines were examined by CBCT.CBCT 3D reconstruction was used to observe the impaction of the canines.Measurements were taken to evaluate spatial relationship between the canine and adjacent structures and resorption of neighboring incisor roots.Results:CBCT was effective to localize the impacted canines.All of the maxillary palatal impacted canines inclinated mesially,angles of impacted ca-nines to occlusal plane were 61.1°±18.1°,there were 8,5,3 and 10 impacted canines found in classⅠ,Ⅱ,Ⅲ and Ⅳ mesial mal-position respectively.3 adjacent lateral incisors and 2 central incisors were extracted because of severely root resorption.Normal occlu-sion was achieved for 26 impacted canines by the traction of the canines into dental arch and reaching the occlusal plane.Conclusion:CBCT can spatially show the palatal impaction of maxillary canines and the relationship to adjacent tooth,can guide the treatment plan and traction direction,therefore increase therapeutic effect.
