OBJECTIVE: To study the discharge medication of tuberculosis inpatients of our hospital for the references of clinical medication. METHODS: The statistics on the quantity of drugs and the amount of money in discharge medication of the tuberculosis patients in our hospital in 2004 was conducted by defined daily dose method,and medication frequency and daily medication sum were computed and the associated data were analyzed as well. RESULTS: The quantity of drugs and the amount of money of the tuberculosis inpatients with medical insurance in discharge medication were less than those without. In addition to first class antituberculosis drugs, the medication frequencies of pasiniazide, rifapentine, ofloxacin and prothionamide were also high;4 agents consisted combined regimen was the chief form of drug combination;Liver protectants were the chief adjunctive therapy. CONCLUSIONS: Medical insurance policy has significant effect on during of administration and consumption sum in discharge medication. Attention should be paid to drug resistance and dependence in the discharge medication of tuberculosis patients.

OBJECTIVE:To evaluate the medical orders in terms of the medication for the inpatients with tuberculosis in our hospital.METHODS:The medical orders for the inpatients in Tuberculosis institute from Dec.7th,2007 to Jan.6th,2008 were synchronously monitored and analyzed.RESULTS:Of the total 5 592 medical orders monitored,1 461 were warned by PASS,of which,562 were warnings about drug interactions,884 about dosage and 15 were about incompatibility.CONCLUSION:Medical orders synchronously monitored by PASS could help correct and monitor the irrational medication.But the function of PASS remained to be strengthened and the data base remained to be enriched and renewed in time.

Objective:To evaluate the utilization of both parenteral nutrition and enteral nutrition drugs for the reference of clinical medication.Method:The statistics on nutrition drugs in a hospital from 2006 to 2008 were conducted by the defined daily dose method.Result:The cost ratio of the nutrition drugs to the total drug consumption increased annually.Glutamine was the leading nutrition drug according to the increase tendency of DDDs.The utilization ratio of enteral nutrition drugs to the whole nutrition drugs increased continuously,from 8.72%to 15.58%during 2006 to 2008.Conclusion:Nutritional support has attracted more and more clinical attention,and DDDs of the enteral nutrition increases rapidly.

AIM　To investigate the effect of hydroxyl camptothecinum(HCPT) on pharmocokinetics of cyclosprine A(CsA) and the membrane lipid fluidity (LFU)of red cell in rabbits. METHODS　The whole blood concentration of CsA in rabbits was monitored using method of FPIA. The LFU of red cell was measured using method of DPH fluorescence polarization technique. RESULTS　The pharmocokinetic parameters of CsA in group CsA+HCPT such as a,V(c),K12 and CL(s) were significantly lower and T1/2(a) was significantly higher (P<0.05) than in group CsA. The concentration of CsA of group CsA+HCPT was higher after injection 0.25, 0.5 and 1.0 h, but have significantly high at 1.0 h point (P<0.05). After injection 0.5,1.0, 1.5 h the LFU of red cell in group CsA+HCPT was higher than in group CsA (P<0.05). The LFU in group CsA was lower that in control at 0.5,1.0 and 1.5 h point (P<0.05). CONCLUSION　HCPT can enhance the whole blood concentration of CsA in rabbits. CsA administrated with HCPT is feasible.

OBJECTIVE　To study the pharmacokinetics of levofloxacin-methane sulfonic acid (LF-MSA)in 8 patients with pulmonary tuberculosis after administration 400 mg orally.METHODS　The concentrations of LF-MSA in serum were measured by HPLC.The pharmacokinetic paramters were obtained using 3P97 program.RESULTS　The results showed that a one-compartment model with 1 st order absorption were fitted for LF-MSA.The average values of tmax was 1.22 h.The concentrations of LF-SA in serum was (4.52±0.72) mg*L-1.The mininal concentrations of LF-AS at 24 hr after a single dose was (0.52±0.26) mg*L-1.The average area under the curve was (48.35±5.38) mg*h*L-1.The elimination half-life was (6.49±1.70) h.The apparent volume of distribution was (77.48±8.33)L.CONCLUSION　According to our study,it was suggested that 400 mg twice daily may be given in order to maintain the concentrations of LF-SA in serum around 24 hours above the minimal concentrations of bactericide.

Objective To investigate the effect of CYP3A5 * 3 and MDR1C3435T polymorphisms on the blood trough concentration of sirolimus in the Chinese renal transplantation recipients with stable renal function and the influencing factors for individual differences.Method 112 cases of Chinese renal transplantation recipients with stable renal function were recruited in this study.Related data of the recipients,including gender,age,height and body mass,were recoded.CYP3A5 and MDR1 genotypes were determined by the direct sequencing.Blood trough concentration of sirolimus was measured by using chemiluminescence microparticle immuno assay (CMIA).The influencing factors of individual differences in sirolimus blood trough concentration was analyzed,and the correlation of CYP3A5 * 3 and MDR1C3435T gene polymorphisms with sirolimus blood trough concentration was evaluated.Result Of the 112 cases,there were 10 cases (8.93％) of CYP3A5 * 1/* 1,49 cases (43.75％) of CYP3A5 * 1/* 3,and 53 cases (47.32％) of CYP3A5 * 3/* 3.Allele frequencies of CYP3A5 * 1 and * 3 were 30.81％ and 69.19％,respectively.There were 31 recipients (27.68％) with MDR1 3435CC,60 (53.57％) with MDR1 3435CT,and 21 (18.75％) with MDR1 3435TT.Allele frequencies for C and T at position 3435 of MDR1 were 54.46％ and 45.54％,respectively.In this study,recipients' CYP3A5 * 3 genotype was the main factor (P =0.000) of sirolimus blood trough concentration,but dose,gender,age,height,postoperative time,the level of serum creatinine,hemoglobin levels,combined use of CsA and MDR1C3435T genotype had no effects on sirolimus blood trough concentration (P ＞ 0.05).sirolimus blood trough concentration/(dose weight) in * 1/* 1,* 1/* 3 and * 3/* 3 recipients was (0.0721 ± 0.0202),(0.1055 ± 0.0395),and (0.1395 ± 0.0537) μg·L-1 ·mg-1 ·kg-1,respectively,The sirolimus blood trough concentration/ (dose weight) in * 1/* 3 recipients was 1.46 times higher than that in * 1/* 1 recipients,and that in * 3/* 3 recipients were 1.93 times higher than that in * 1/* 1 recipients.There was significant difference in sirolimus blood trough concentration/(dose weight) between recipients with different CYP3A5 * 3 genotypes (P =0.000).Conclusion The CYP3A5 * 3 gene polymorphism is closely related to the blood trough concentration/dose of sirolimus,and is the main factor of the blood trough concentration of sirolimus between individuals.
