Objective To compare whether there is a difference in medical cost of intensive care unit(ICU)pa-tients with catheter-associated infection (CAI)between before and after targeted intervention.Methods CAI in ICU patients in 2010(pre-intervention group)and 2013 (post-intervention group)were investigated by retrospective survey,hospitalization cost of two groups of patients before and after intervention was compared.Results The morbidity and mortality in patients with CAI both decreased significantly after intervention,morbidity of healthcare-associated infection(HAI)decreased from 13.47% in 2010 to 4.41 % in 2013,mortality decreased from 10.36% in 2010 to 2.2% in 2103.Total hospitalization cost,blood transfusion cost,and cost of special material before and af-ter the implementation of targeted intervention all significantly different (all P <0.05),the difference of procalcito-nin and antimicrobial agents cost were also significant(all P <0.05).Conclusion Medical cost in ICU patients with CAI decreased after intervention.

Objective To analyze the correlation of real-time fluorescent quantitation PCR(FQ-PCR)for detecting HCV-RNA loading and the chemiluminescence immunoassay(CLIA)for detecting anti-HCV antibody.Methods 587 samples of anti-HCV an-tibody positive detected by CLIA were furteher detected HCV-RNA by FQ-PCR.Results Among 587 samples of anti-HCV anti-body positive by the CLIA screening,225 samples were HCV-RNA negative and 362 samples were HCV-RNA positive detected by FQ-PCR,and the positive rate was 61 .67%,moreover,which was positively correlated with the S/CO ratio detected by CLIA.Con-clusion The positive rate of HCV-RNA is positively correlated with the S/CO ratio detected by CLIA.The result of HCV-RNA can be predicted according to the S/CO ratio.

Objective To evaluate the usefulness of anti -HCV signal-to-cutoff (S/CO)ratio, AST, ALT and the combined examination of anti-HCV S/CO, AST, ALT for predicting HCV RNA results by a model of logistic regression and receiver -operating characteristic (ROC) curve.Methods Five hundred and eighty -eight anti-HCV positive samples were tested by ELISA , followed by RT-PCR to detect HCV-RNA and enzyme rate method to detect AST, ALT.Patients were divided into viremia and non -viremia groups according to HCV-RNA results.Logistic regression and ROC curve analysis was performed to evaluate the diagnostic accuracy of each index for a diagnosis of viremia.Results The serum anti-HCV S/CO ratio, AST, ALT of HCV-RNA positive group were higher than HCV-RNA negative group, showing significant statistical difference ( P AST >ALT.The Area Under Curve(AUC) of the combined examina-tion of anti-HCV S/CO ratio, AST and ALT was 0.949(95% confidence interval,0.932 to 0.966), higher than the AUC of anti-HCV S/CO ratio, AST and ALT single index examinations , which was 0.894(95 % confidence interval, 0.862 to 0.926), 0.823(95%confidence interval, 0.789 to 0.856) and 0.788(95% confidence interval, 0.750 to0.826 ) respectively.C onclusions The diag-nostic relevance of the three biochemical markers for predicting the presence of viremia was anti -HCV S/CO ratio >AST >ALT.The combined examination of anti-HCV S /CO ratio, AST and ALT in predicting hepatitis C viremia is superior to any single index examina -tion and it can increase the detecting ability of HCV -RNA greatly.
