OBJECTIVE:To observe the efficacy and safety of the effective blood concentration of cyclosporin A in patients after bone marrow transplantation.METHODS:By fluorescence polarization immunoassay(FPIA),the whole blood trough concentration of CsA in 14 patients after undergoing bone marrow transplantation was monitored for 216 times in total from day 1 to day 466,and the monitoring results were analyzed.RESULTS:The effective blood concentrations of CsA in patients with chronic myelocytic leukemia(CML),acute non lymphocytic leukemia(AML),acute lymphoblastic leukemia (ALL),Mediterranean disease(THAL),and pancytopenia were(50～450) ng?mL~(-1),(100～450) ng?mL~(-1),(100～350) ng?mL~(-1)(200～500) ng?mL~(-1),and(250～500) ng?mL~(-1),respectively.Rejection reaction appeared in 7 cases after bone marrow transplantation,with whole blood trough concentration of CsA ranged from 67.4 ng?mL~(-1) to 189.34 ng?mL_(-1) (125.44?39.56 ng?mL~(-1)on average).Adverse drug reaction appeared in 3 cases,with trough concentration of CsA ranged from 412.5 ng?mL~(-1) to 548.62 ng?mL~(-1)(481.39?68.08 ng?mL~(-1) on average).CONCLUSION:Timely monitoring of plasma concentration of CsA and modifying of the dosage regimen can avoid the occurrence of rejection reaction and adverse drug reaction,which is of great significance for patients' medication safety and efficacy.

Objective To investigate the therapeutic effects of pulsed CO2 laser irradiation in the treatment of syringoma. Methods A retrospective comparison was performed between 28 syringoma patients treated with a pulsed CO2 laser and 30 patients treated with a continuous CO2 laser. The therapeutic effects and treatment complications were compared statistically. Results The treatments were rated effective for all patients in both groups. The outcome was rated " excellent" for 86. 7% of the pulse-treated group and 78. 6% for those treated with continuous las-ing. There was no significant difference between the two groups. There was a significant difference in the rate of pigmentation and atrophic scarring. The pulsed group showed lower levels of both effects than the continuous group. Conclusion The pulsed CO2 laser is a better tool for treating syringoma in terms of safety, efficiency and side effects.

OBJECTIVE:To develop the drug traceability management system in outpatients of medical institutions,and gradu-ally improve its traceability management. METHODS:Based on barcode technology,drug traceability management system in outpa-tients of medical institutions was independently developed,introducing it from system environment,framework design and system function,and the application results were evaluated in terms of differences in dispensing time,deployment error,drug withdrawal treatment and applicability investigation. RESULTS:The system was developed on hospital information system network environ-ment,which was designed by combination of client/server(C/S)network system(B/S)and set function modules as follows as role rights management,data extraction,information control,data acquisition and data query. The system can match with drug electron-ic surveillance code,commodity code and other traceable barcodes,achieve drug tracing from hospitals to users through software interaction,as well as the computer-aided calibration in dispensing to effectively reduce outpatient's dispensing error. The average time for each outpatient prescription prolonged 9 s after using the system;24 dispensing errors and 4 non-normal withdrawals were prevented within 1 month;100% surveyed pharmacists expressed approval for the system's applicability. CONCLUSIONS:The system can achieve the drug suitability management in outpatients,which has shown good applicability and further improved drug safety management and control capabilities in medical institutions.

OBJECTIVE:To determine ampicillin concentration in human plasma by HPLC.METHODS:The chromatographic column was Waters Sunfire C18 with mobile phase consisted of acetonitrile and 0.05 mol?L-1 potassium dihydrogen phosphate(6.5∶93.5,V∶V)at a flow rate of 1.2 mL?min-1.The UV detection wavelength was 210 nm;the column temperature was 35 ℃ and the injection volume was 20 ?L.RESULTS:The linear range of ampicillin was 0.2～16.0 ?g?mL-1(r=0.999 9).The limit of quantization was 0.2 ?g?mL-1.The average methodological recovery was 99.88%～104.45%,and the average extraction recovery was 95.69%～100.56%.Both the inter-day RSD and the intra-day RSD were all less than 10%.CONCLUSION:This method is stable,rapid and sensitive,and suitable for the pharmacokinetic study for ampicillin preparation.

Hepatitis B virus ( HBV) is an important pathogen threatening to human health. Up to date, various of cell infection models and animal models for HBV and the host are widely used in the exploring research of infection mechanism, new drug development and effective therapeutic method for HBV. However, these models have some defects, such as low infection rate, rather short infective stage, and comparatively large species differences with human, and so on. Among them, the biggest problem is that these models cannot completely simulate HBV infection process and pathological changes naturally occurred in human. Herein, the major HBV infection models developed in the past fifteen years, as well as the latest research progress, are presented as a brief review, to provide a reference for constructing novel HBV infection models in the future.
