RESUMEN
Objective To investigate the diagnostic value of combined detection of serum alpha fetoprotein (AFP),thymidine kinase 1(TK1)and secreted protein Dickkopf-1(DKK1)in patients with primary liver cancer(PHC).Methods 85 patients with PHC admitted to the hospital from August 2015 to October 2016 were selected as PHC group,and 73 patients with benign liver disease as benign liver disease group,and 80 ca-ses healthy subjects as the control group.The serum levels of AFP,TK1 and DKK1 were detected in three groups,and the differences in each group were compored,and the diagnostic sensitivity,specificity,positive predictive value,negative predictive value and accuracy were calcuated.The diagnostic value of each index was analyzed by logistic regression.Results The serum AFP,TK1 and DKK1 levels in PHC group were signifi-cantly higher than those in benign liver disease group and control group(P<0.05),the serum AFP TK1 and DKK1 levles in benign liver disease group were significantly higher than those in the control group(P<0.05);the sensitivity,accuracy and negative predictive value of AFP + TK1+ DKK1 joint detection were sig-nificantly higher than that in the single index detection(P<0.05);Logistic regression analysis showed that AFP,TK1 and DKK1 were closely correlated with the diagnosis of PHC(P<0.05).Conclusion The com-bined detection of serum AFP,TK1 and DKK1 can significantly improve PHC positive diagnosis rate,which is of great significance for clinical early diagnosis and effective treatment,and is worth popularizing.
RESUMEN
Objective To analyze antibacterial resistance and distribution of Acinetobacter baumanni in clinical departments,in order to provide references for hospital infection control.Methods Clinical isolates of Acinetobacter baumanni from January 2012 to July 2014 were collected.Bacterial identification and antibacterial susceptibility tests were carried out by using the VITEK 2 Compact automatic bacterial identification system,and results of resistance of Acinetobacter baumanni were analysed by using the WHONET5.0 software.Results A total of 285 strains of Acinetobacter baumanni were isolated and mainly were isolated from the intensive care unit(ICU)(accounted for 47.0%),most of the infected patients were male,and patients aged 45 years and over ac-counted for 70.5%.The resistance rate of aztreonam against Acinetobacter baumanni(71.9%)was the highest and the lowest was levofloxacin(25.7%).The resistance rates of most of antibacterials tested in this study were approximately 50%,and resistance rates of piperacillin-tazobactam and imipenem was approaching 40%.Conclusion Strains of Acinetobacter baumannii are mainly i-solated from ICU and antibacterial resistance of isolates is serious.Hospitals should strengthen infection control and promote ra-tional use of antibacterials according to results of antibacterial-susceptibility test,so as to reduce antibacterial resistance.
