Objective: To analyze the correlation between HD-MTX blood concentration and acute drug-induced liver and kidney injury in the patients with osteosarcoma, and investigate the significance of HD-MTX concentration in the monitoring of liver and kidney toxicity. Methods: A total of 56 osteosarcoma patients treated with HD-MTX were selected, and after HD-MTX treatment, the blood concentration of MTX was detected by an HPLC-UV method in 48 h and 72 h after the administration. The liver and kidney function were measured at the same time. The correlation between the different concentrations of MTX and the change of liver and kidney func-tion was analyzed. Results: All the patients were monitored MTX blood concentration at different time points. After the 48-hour HD-MTX treatment, 4 patients (7. 14% ) were with acute drug-induced liver injury and 13 patients (23. 21% ) showed drug-induced kid-ney injury. The average C48hof liver injury was (2.90 ±0.78) μmol·L-1, and the average C48hof kidney injury was (1.65 ±1.12) μmol·L-1. After the 72-hour HD-MTX treatment, 7 patients ( 12. 50% ) were with drug-induced liver injury and 16 patients (28.57%) showed drug-induced kidney injury. The average C72hof liver injury was (0.30 ±0.17) μmol·L-1, while the average C48hof kidney injury was (0. 29 ± 0. 29) μmol·L-1. The function indices of liver ( ALT, ALP and TBIL) and kidney ( SCr) were significantly higher than those in the normal group (P<0. 05), and the blood concentration of MTX was partly significantly correlated with those indicators. Conclusion: There is a certain correlation between MTX induced injury and the blood drug concentration at par-ticular points, and C48hmay be more valuable to predict drug-induced liver and kidney injury.

Objective To investigate status of the intravenous use of antibiotics in outpatients and emergency patients of a tertiary first-class hospital, and provide a reference for developing management measures in next step. Methods By a retrospective method,all the prescriptions using antibiotics by intravenous administration in outpatients and emergency department patients from a tertiary first-class hospital in 2013 were extracted from the hospital information system. The categories of antimicrobial agents,proportion of intravenous use of antimicrobial drugs,ranking of the antibiotic consumption sum and defined daily dose,and the top 10 clinical departments or wards intravenously using antimicrobial drugs were chosen to analyze. The data in 2014 were extracted as a comparison. Results Outpatients and emergency department patients respectively used 8 categories 31 kinds and 8 categories 30 kinds of intravenous antimicrobial drugs, with high consumption of cephalosporins and restricted antimicrobials such as sodium cefoxitin.Intravenous use of antimicrobial drug prescription proportion in emergency department is higher than that in outpatient department. Conclusion After intervention in 2014, antibiotic consumption is effectively controlled as compared that in 2013. But management should be strengthened and appropriate interventions should be taken to ensure the use of intravenous antibiotics in a safe,effective and economical manner.

Objective To discover the effects of the Prescription Administrative Policy in force on the quality of the prescriptions in a tertiary hospital in 2007. Methods The prescriptions of 400 cases were sampled systematically for evaluation, and 60 patients were interviewed. Results The average eligibility rate of the prescriptions was but 37. 2% in this hospital, which was mainly plagued by incompleteness, nonstandard and irrationality found in prescriptions. Implementation of the Policy contributed to a significant improvement of some indicators. For example, the eligibility rate increased by 12. 2% (P=0. 004) ,the percentage of the use of antimicrobial agents dropped significantly (P=0. 001),and the percentage of generic names used rose significantly (P = 0. 000). Conclusions The implementation of the Policy is highly positive for prescription quality.

OBJECTIVE:To study the stability of mixture of ciprofloxacin injection and metronidazole in glucose injection at high temperature(50℃~70℃)and at room temperature((20?1)℃)storage METHODS:UV-spectrophotometry method was used for determining the contents of ciprofloxacin and metronidazole The changes in the content,pH value and appearance were observed by classical constant-temperature experiment and room temperature storage RESULTS:The linearity ranges for ciprofloxacin and metronidazole were 1 00~10 02?g/ml and 2 01~20 08?g/ml;the average recoveries were(101 30?4 28)% and(99 58?1 63)%,respectively The heat decomposition products at 70℃ for 8 hours did not interfere with the assay The relative contents of ciprofloxacin and metronidazole were more than 95% and there were no significant changes of the pH value and the color with accelerating experiment for 8 hours at 50℃~70℃ and for 120 hours at (20?1)℃ CONCLUSION:We found that admixture of ciprofloxacin with metronidazole in glucose solution was stable at high temperature for 8 hours and at room temperature for 120 hours Ciprofloxacin injection was compatible with metronidazole in glucose injection

AIM To determine the concentration of paeonol in the bulk drug and injection, a method of reversed-phase high performance liquid chromatography (RP-HPLC) was developed. METHODS Lichrospher C_ 18 column(4.6 mm?250 mm, 5 ?m)was used with methanol-acetonitrile-water(30∶40∶30)as mobile phase at a flow rate of 0.8 ml?min -1 . 20 ?l of sample was injected into the C_ 18 column where the temperature was 25℃. The detection wavelength was 274 nm. RESULTS The linear regression equation for paeonol was = 3 772.525 8 X- 0.747 4 (r = 1.000 0, n =5) under the linearity range from 0.02 mg?L -1 to 25.60 mg?L -1 . The average recovery was 99.87%. The relative standard deviations of the intra-day and inter-day were less than 4%. CONCLUSION The method is simple and rapid, which may be used for the determination of paeonol and its preparation for different purpose.
