Herald of Medicine.2017;36(9):962-966. doi:10.3870/j.issn.1004-0781.2017.09.003

Objective To estimate the value of nitrofuratoin in uncomplicated urinary tract infection by examining antimicrobial resistance of Escherichia coli (E.coli) strains isolated from the patients.Methods The antimicrobial susceptibility information was collected from two projects: an antimicrobial survey of clinical urine specimens in 20 hospitals in 15 provinces during 2004-2012 and CHINET Antimicrobial Resistance Surveillance Program during 2005-2014.Then the clinical consumption of nitrofuratoin was analyzed according to the data of sample hospitals from 6 cities of Yangtze River system between 2011 and 2015.Results The antimicrobial susceptibility of E.coli strains showed that the resistance rate to cephalosporins and fluoroquinolones were above 50% during the last decade.Meanwhile,the resistance rate to nitrofuratoin was below 10%.Conclusion Nitrofuratoin,which is an old drug in the treatment of urinary tract infection,is famous for its broad-spectrum antimicrobial activity and high sensitivity to ESBLs producing or non-ESBLs producing strains of E.coli.It is efficacious,safe and cost-effective in the treatment to uncomplicated urinary tract infection in women.Therefore,it is highly recommend that rational use of nitrofuratoin in the clinical practice.

Herald of Medicine.2017;36(9):956-961. doi:10.3870/j.issn.1004-0781.2017.09.002

Pharmacogenomics does not only bring the connection of genes,medicines and diseases,but also become a powerful tool for clinical pharmacists.Pharmacogenomics is commonly used in clinical practice,especially in the implementation of genetic-test results for guiding rational use of medicines.The genotyping results of genes can provide good individualized medication guidance for patients,which can be confirmed by clinical use of the clopidogrel and warfarin.As a member of the clinical treatment team,clinical pharmacists should take advantage of pharmaceutical and pharmacogenomics information to promote rational use of medicines.

Herald of Medicine.2017;36(9):951-955. doi:10.3870/j.issn.1004-0781.2017.09.001

In order to favor the growth and development of the fetus,the maternal-placental-fetal unit is characterized by profound physiologic changes.These adaptations may affect maternal and fetal absorption,distribution,placental transfer,metabolism and excretion of drugs.When evaluating drug use in pregnancy,understanding both pregnancy physiology and the gestation-specific pharmacokinetics of different drugs is necessary to achieve effective treatment and limit maternal and fetal risk.This topic will focus on the pharmacokinetics and safety of drugs during pregnancy in light of changes in maternal physiology and function of placental.
