PlexinC1 is a large transmembrane protein widely distributed,which belongs to receptor system. PlexinC1 is expressed by monocyte,T-cells,B-cells,dendritic cells,neutrophils,and platelets. Recent researches showed that plexinC1 was intensely associated with lung injury,asthma and pulmonary fibrosis. PlexinC1 binded to its corresponding ligand and activated cellular signal pathway,which then participating in pathophysiologic processes of diseases mentioned above. Reasonably,PlexinC1 influences the development, prognosis of lung diseases and would provide a new target in control and treatment of lung diseases. This pa-per reviewed simply the formation,distribution,function of plexinC1 and the role of it playing in the associat-ed lung diseases.

Objective To study a novel method for the high-dose-rate brachytherapy (HDR) CT image to the intensity modulated radiation therapy (IMRT) CT image deformable image registration and dose accumulation.Methods The applicator in the HDR CT image is first segmented and removed,then a deflation step is performed on the applicator-free HDR CT image by solving the Navier-Stokes equation.Demons algorithm is utilized to register the deflated HDR CT image to the IMRT CT image,along with the HDR dose.The deformed HDR dose is then added on the IMRT dose and yield the final accumulated dose.Results The HDR CT image and IMRT CT image,as well as the corresponding dose distribution,from five cervical cancer patients are used for evaluation of the proposed algorithm,the results show that the proposed method can effectively get rid of the influence of the applicator and produce an accurate accumulated dose.Conclusions Dose accumulation and supervision is an important step in adaptive radiotherapy for accurate dose delivery and treatment plan re-optimization.The proposed method in this study can effectively accumulate the HDR dose to the IMRT dose domain,and the accuracy is proved to be sufficient for clinical needs.

OBJECTIVE To identify the antibiotic resistance,homology and the carbapenemases determinants of imipenem-resistant strains of Acinetobacter baumannii isolated from elderly in the Zhejiang Hospital.METHODS All 142 strains of A.baumannii were isolated from Zhejiang Hospital through Jan 2005 to Jan 2007.K-B method was used to screen imipenem-resistant strains.The MICs of imipenem-resistant strains to 14 antimicrobial agents were determined by agar dilution method.The homology of these isolates was analyzed by pulse-field gel electrophoresis(PFGE).The coding genes of carbapenamases and the gene environments were investigated by PCR,clone,and sequencing.RESULTS Ninety-seven strains of imipenem-resistant A.baumannii were isolated from 142 strains.All of the strains of carbapenem resistant A.baumannii belonged to 4 epidemic PFGE-clones.Ninety carbapenem resistant strains contained OXA-23-like carbapenemase gene and 91 isolates were positive for OXA-51-like gene. OXA-23-like gene of 86 strains was just on the down-stream of insert sequence ISAba1.OXA-51-like gene of 6 strains had an ISAba1 sequence just on the up-stream.CONCLUSIONS All imipenem-resistant strains of A.baumannii are pan-resistant isolates.Clone dissemination is the most important style of strains spread.No OXA-24-like,OXA-58like,IMP-like,and VIM-like gene are detected.OXA-23-like and OXA-51-like gene are the most popular carbapenemases coding genes of these strains in the Zhejiang Hospital.ISAba1 has close relationship with OXA type carbapenemases genes in Zhejiang Hospital.
