Objective To study the impact of F000 on cited papers in medical journals. Methods Papers in the 4 years after they were published from 2006 to 2008 that were recommended by F1000 served as No. 1 control group, papers in the 4 years after they were published from 2006 to 2008 that were not recommended by F1000 served as No. 2 control group, Web of Science-covered papers in the 1-6 years after they were published from 2006 to 2008 served as group 3. The cited papers in group 3 were calculated. The total cited papers in the first 3 years and the second 3 years after they were published were analyzed with SPSS 11. 0 and identified by paired t test. Results The number of cited papers reached its peak in the 4th year after they were published. The number of cited papers reached its peak in the third year after they were published in No. 1 and No. 2 control groups. Paired t test showed no significant difference in the number of cited papers in group 3 from that in No. 1 and No. 2 control groups. How-ever, the number of cited papers and that of total cited paers in group 3 were significantly different from those in No. 1 and No. 2 control groups. Conclusion F1000 can significantly influence the citation behaviors in medical journals.

Objective:To compare the tissue biocompatibility of domestically manufactured NiTi alloy before and after thermal surface oxidation under 3 different temperatures.Methods:Domestically manufactured NiTi alloy was oxidized in air (group A)and subjected to 30 min heat treatment at 400℃(group B),500℃(group C),and 600℃(group D)to form different protective oxide surface layers in presence of argon(607.95 kPa).Wire samples from A,B,C and I3 groups were subcutaneously implanted in guinea pigs.Guinea pigs received 317L stainless steel transplantation(group E)and sham-operation group(F)were taken as control.The order of inflammatory cell infiltration and tissue hyperplasia around implanted materials were observed 1,2,4,and 8 weeks after implantation.Results:The peak time of inflammatory cell infiltration and fibrous hyperplasia were at the first and fourth week after implantation.The inflammatory cell infiltration and fibrous hyperplasia were both slight and all met the GB/T 16886.6-1997 in vivo implantation standard.The order of inflammatory cell infiltration and thickness of capsule walls from low to high was F

Objective To evaluate the safety,biocompatibility and efficacy of transcatheter closure of atrial septal defect(ASD)with no stainless-steel-screw occluder in canine model.Methods The device was constructed from superelastic Nitinol wires tightly woven into two flat disks and sewed with polyester fibers inside,with a pliable loop on the right-atrial-disk of the device,connecting to the delivery cable.ASD was created by transcatheter puncture and balloon dilatation and then closed by occluder under fluoroscopy in the catheterization laboratory.The location and the influence of the implanted device on function of tricuspid valve and mitral valve were evaluated by echocardiography.At 1,2,3 and 6 months after the operation,the animals were killed and autopsy was conducted.Results Eight dogs with puncture-produced ASD underwent ASD closing procedure successfully.The occluder showed no influence on the function of MV and AV demonstrated by echocardiogram.The two disks of the implanted device were covered with a smooth intact neogenesis layer in all dogs.Endocardial cells fully covered the surface of the two disk without inflammating reaction 3 months later. There was no evidence of corrosion on the surface of the nitinol wire removed from the dog after 6 months.Light microscopic examination of the liver,kidney,lung and spleen showed no evidence of embolization and inflammation.Conclusion Transcatheter ASD occlusion with new-type occluder is safe,feasible,effective and good biocompatibility with a good prospective clinical application.
