OBJECTIVE:To discuss the effect of drug price reduction on the use of antimicrobial drugs for patients with tumor in our hospital.METHODS:The consumption sum,DDDs,and DDC of antimicrobial drugs during 8 times of drug price reduction from 2005 to 2007 were analyzed retrospectively.RESULTS:In respect of the consumption sum,the proportion of antimicrobial drugs accounted for 9.47%～7.27% of the total,which dropped year by year.However,the total DDC of the antimicrobial drugs increased year by year.The changes of DDDs and the DDC of all kinds of the antimicrobial drugs showed a varied tendency.CONCLUSION:The price reduction for the antimicrobial drugs is helpful for the rational use of the antimicrobial drugs.

With the development of metabonomics and modern instrumental analysis and bioinformatics, pharmaco-metabonomics has been rapidly put into the diagnosis and treatment of tumor, with a particularly important role in the evaluation and prediction of efficacy, toxicity and resistance of anti-tumor drugs, indivisualized medication and detection of tumor markers. This paper reviews the concept and methodologies of pharmaco-metabonomics, as well as the latest research advances of pharmaco-metabonomics in the diagnosis and freatment of tumors.

Objective To investigate the use and application trend of antibiotics in a cancer hospital in Tianjin,so as to provide reference for the rational clinical use of antibiotics.Methods The related data of antibiotics in the hospital from January 2018 to January 2021 were selected,and the utilization rate,defined daily doses(DDDs)of drugs,antibiotics use density(AUD),defined daily cost(DDC)and ranking ratio(B/A)of antibiotics were statistically analyzed.Results In 2018-2021,the annual use of antibiotics,utilization rate of antibiotics and AUD showed a downward trend.The mean annual utilization rate of antibiotics was 22.42％,and the mean annual AUD was 26.79 DDDs/(100 person·d).The top three antibacterial drugs in terms of annual consumption and DDDs were cephalosporins,carbapenems and penicillins.The main antibacterial drugs at all levels were unrestricted.There were 6 antibacterial drugs with DDC＞100.Voriconazole had the highest DDC.The B/A of ciprofloxacin sodium chloride,moxifloxacin tablets,Latoxefin sodium,moxifloxacin sodium chloride was close to or equal t0 1,indicating that the synchronization of these antibacterial drugs was good.Conclusion In 2018-2021,the selection and use of antibiotics in the cancer hospital in Tianjin was reasonable,and the clinical application indicators met the national standards.
