Objective To investigate the effect of simple vertebral canal decompression for treating degree 1 senile degenerative lumbar spondylolisthesis .Methods 62 cases of degree 1 senile degenerative lumbar spondylolisthesis from January 1998 to January 2012 were retrospectively analyzed .The patients were surgically treated by simple vertebral canal decompression and included 20 males and 42 females ,aged from 65-82 years(mean 68 years) ,with the disease history of 2-7 years(average 3 .3 years) .The clini-cal effects in average postoperative 2 years and 8 .2 years were evaluated by Japanese Orthopaedic Association Scores (JOA ) and Visual Analogue Scale/Score(VAS) .Results The preoperative JOA score was 9 .7 in average and the JOA scores in average post-operative 2 years and 8 .2 years were 11 .7 and 12 .8 respectively(P<0 .05);the preoperative VAS score averaged 7 .8 ,which after operation were 2 .3 and 2 .6 respectively(P<0 .05) .Complications were observed in 16 cases .4 cases accepted reoperation .Conclu-sion In the basis of the actively controlling other organ systems diseases in perioperative period ,simple vertebral canal decompression is an effective method for treating degenerative vertebral canal spondylolisthesis and can obtain the satisfactory therapeutic effect .

Objective To systematically evaluate the efficacy and safety of intracoronary abciximab administration as compared to intravenous in percutaneous coronary intervention (PCI) .Methods A search was conducted in PubMed ,EMBASE ,OVID ,CBM , CNKI and VIP for the randomized controlled trials (RCTs)of intracoronary abciximab administration versus intravenous in PCI , from the date of their establishment to September 30 ,2013 ,and the domestic relevant papers published in recent 1 year were also searched manually ,the bibliographies of the included studies were searched too .According to the criteria of the cochrane Hand-book ,two reviewers evaluated the quality of the included RCTs and extracted data independently ,and then the extracted data were analyzed by using RevMan 5 .1 software .Results 8 RCTs involving 10 articles with 4 150 patients who treated with PCI were in-cluded .The results of meta-analysis showed that :(1) Compared intravenous administration and intracoronary abciximab administra-tion ,there were no significant differences in the two groups for the major adverse cardiovascular event (MACE) and the mortality (OR=0 .78 ,95% CI 0 .54-1 .14 ,P=0 .20) ,(OR=0 .56 ,95% CI 0 .24-1 .30 ,P=0 .18) .(2)Compared with intravenous adminis-tration ,intracoronary abciximab administration were not associated with any excess of major bleeding complications :(OR=1 .26 , 95% CI 0 .78-2 .02 ,P=0 .35) .Conclusion Compared with standard abciximab regimen of intravenous bolus ,intracoronary admin-istration had equivalent effects in clinical outcomes in patients undergoing PCI ,and did not increase the incidence of bleeding events .
