Warfarin is widely used as one of the coumarins anticoagulation drugs in the clinical.Every physician has been disturbed by its narrow therapic index and bleeding complications.It is a difficult thing for the doctor to use it rationally.However,recently,with the rapid development of molecule biology,some research find that gene polymorphism of pharmacodynamics and pharmacokinetics cause the individual variability in drug response.In this review,we focus on the latest development in pharmacogenomics of warfarin at home and abroad in order to give some suggestions for the individual use of warfarin.

OBJECTIVE:To set up data management system for therapeutic drug monitoring(TDM),and to realize the remote database access by means of network.METHODS:The TDM data management system was set up by means of com?puter network technology and database technology.RESULTS&CONCLUSION:A satisfactory management interface and remote database access were available through TDM Data management system,which were sure to benefit clinic and patients.

OBJECTIVE:To investigate the status of hospital infection and the antibiotic resistance of pathogenic microorganisms so as to provide references for empirical treatment of hospital infection and rational clinical administration of antibiotics.METHODS:The pathogenic microorganism infection of different specimen and the results of drug susceptibility test on the pathogenic microorganisms in hospital infection from 2005 to 2008 were analyzed.RESULTS:The ratio of gram-positive coccus to gram-negative bacillus in hospital infection was 2∶1,and the susceptibility test showed that pathogenic microorganisms in hospital infection had different degree of antibiotic resistance.CONCLUSION:Monitor on the antibiotic resistance of pathogenic microorganism is of utmost importance for the rational use of antibiotics in the treatment of hospital infection.

OBJECTIVE:To establish an HPLC method for determining nicardipine hydrochloride(NCD) microspheres in cerebrospinal fluid(CSF) of rabbits by HPLC.METHODS:NCD microspheres were injected into the cistern of rabbits.Cerebrospinal fluid was sampled at different time points and NCD was separated on Agilent-Zorbax column at a flow rate of 1.0 mL?min-1 with column temperature of 30 ℃.The mobile phase consisted of methanol-water(75 :25,pH=6.0) and detection wavelength was set at 236 nm.RESULTS:The linear range of NCD was 2～128 ng?mL-1(r=0.999 8) with recovery of 98.07%.The RSD of intra-day and inter-day were both below 1.47%.The LOD was about 0.5 ng?mL-1.On 3～11 day after medication,the concentration of NCD fluctuated within(14.15?0.37) ng?mL-1.CONCLUSION:The method is simple,rapid and accurate for determination of NCD in cerebrospinal fluid of rabbits.

OBJECTIVE: To facilitate automatization in pharmacy of inpatient departments and promote the management level and quality of pharmaceutical service.METHODS: The transformation of operation mode and administration mode were observed after developing automatization in the inpatient pharmacy departments.RESULTS & CONCLUSIONS: The intelligent location storage and auto single-dose dispenser were combined with electronic information transmission technology to facilitate the automatization of inpatient pharmacy.The dispensing process of inpatient pharmacy is optimized and improved and standardized management of drugs is consummated.The efficiency and accuracy of the dispensing of tablets and injections are improved.Error rates of drug dispensary and costs of storage are cut down.Labor intensity and the number of staff are also reduced and the quality of pharmaceutical service in the inpatient pharmacy departments is upgraded roundly.

OBJECTIVE:To assess the stability of the quality control of FPIA for monitoring of CsA and MEIA for monitoring of FK506.METHODS:The quality control on the blood samples of patients receiving therapeutic drug monitoring of CsA and FK506 from June to August in 2007 were subjected to a continual assessment and analysis to investigate the stability and accuracy of the quality control.RESULTS:The mean recoveries of the low,middle and high concentrations of CsA and FK506 were 93.14%～97.65% and 97.70%～103.09% respectively,with RSD at 4.41%～5.37% and 10.44%～14.23% respectively,which accorded with the requirement for biological sample determination stated in the Chinese Pharmacopoeia.CONCLUSION:The methods of FPIA for monitoring of CsA and MEIA for monitoring of FK506 were accurate,and worth to be applied in clinical to guide individualized medication.

OBJECTIVE:To investigate the characteristics of adverse drug reactions (ADR) caused by quinolones in our hospital and to promote their rational use in clinic. METHODS: By a retrospective review,a total of 199 quinolones-induced ADR cases collected from May 2004 to December 2007 in our hospital were analyzed statistically in respect of patients' gender and age,drug species involved,past ADR history,route of administration,clinic manifestations,etc. RESULTS: A total of 9 kinds of quinolones involved in the 199 ADR cases,of which,118 cases were induced by levofloxacin,16.1% had past ADR history,93.5% of the ADR cases were induced via intravenous drip,and most common presentations of the ADR were lesions of skin and its appendants as well as digestive system. There were 7 serious ADR cases. CONCLUSION: The indications of quinolones should be controlled strictly,which should be preferably administered orally and monitoring of its administration should be emphasized in clinical practice to decrease and avoid the occurrence of ADR.

Objective To observe the effects of fluvastatin on proliferation and apoptosis of HL-60 cells,and to offer the theoretical evidence for tumor treatment.Methods HL-60 cells were divided into:fluvastatin groups(0.5,5.0,10.0 and 20.0 ?mol?L-1),HL-60 control group,positive control group(treated with 10.0 ?mol?L-1ATRA).The live cell number was counted for cell proliferation assay.The growth inhibitory rate of HL-60 cells was detected using CCK-8 kit.The cell cycle distribution and apoptotic rate were measured using flow cytometry assay.Results Compared with control group,after HL-60 cells were treated with 0.5,5.0,10.0 and 20.0 ?mol?L-1of fluvastatin for 1-4 d,the number of live cells decreased in different level(P

OBJECTIVE:To study the stability and to predicate the expiration date of betamethasone cream.METHODS:The HPLC method was used to determination the content of betamethasone,the stability test of cream was done by initial mean velocity method and strong light exposure experiment,respectively.RESULTS:The linear concentration range for betametha?sone cream was0.25～8?g/ml(r=0.9991),the average recovery rate was98.56%,RSD=0.78%;The content was highly correlated to temperature,whereas on which the light exposure did little effect.CONCLUSIONS:Betamethasone cream should be stored under room temperature and in a cool place,it is predicted that the expiration date of betamethasone cream is1year.
