Objective To explore the effect and action principle of extracorpoporeal shock wave(ESW) combine hyperbaric oxygen(HBO) in bone nonunion treatment .Methods Totally 50 standard New Zealand white rabbits were chosen ,and 48 rabbits were successfully made to models .Then ,they were divided into four groups by using the random number table ,12 in each group . The group A was in ESW combine HBO group ;The group B was in hyperbaric oxygen group ;The group C was in pure ESW group ;The group D was in control group .X‐ray inspected before treatment and after treatment in 4 、8 、12 weeks .The calcium con‐tent was checked ,the osteoblast in bone callus was observed by the optical microscope ,and the data was analyzed by statistics .Re‐sults There was a significant difference in 4 ,8 ,12 weeks between group A and group B ,C ,D in the nonunion gap(P< 0 .05) ,there was significant difference in 4 ,8 ,12 weeks between group A and group B ,C ,D in the generation bone callus(P< 0 .05) .Callus calci‐um content of group A was higher than group C ,the difference was statistical significance(P< 0 .05) ,there was significant differ‐ence in 4 ,8 weeks between group A and group C in callus osteoblast count(P < 0 .05) .Conclusion ESW combine HBO treatment for bone nonunion is better than pure ESW therapy ,simple hyperbaric therapy has no obvious help for the treatment of bone nonun‐ion ,HBO can be used as a good synergy method in the extracorporeal shock wave treatment of bone nonunion .

Objective To identify epitope of neutrophil-activating protein(NAP) of Helicobacter pylori(Hp).Methods Using the mouse monoclonal antibodies against NAP as selective molecular and immunoscrcening phage-display random 7-peptides library.The positive clones were sequenced and analyzed.Phage clones were chosen to immunize mice and to evaluate the potential of phagotopes as effective vaccines.Results One mimotope(FAHLATQ)showed a good match with the NAP at 140-143 AA(AHLA)and the serum of mice induced by the phage clone clearly recognized NAP.Conclusion This study suggests thatthe antigenic epitope could be mapped through screening the phage-display peptide library with monoclonalantibody and a mimotopo of NAP providing an ahernative approach for the diagnosis and development of avaccine for Hp.
