OBJECTIVE:To assess the ability of suppliers and manufacturers in dealing with drug quality problems so as to provide reference for hospital in optimizing future suppliers and manufacturers.METHODS:The drug quality registration form in drug storehouse in 2007 in our hospital was analyzed in respect of the quality of drugs which were classified into type A and type B.RESULTS:The A-type drug quality problems,i.e drug quality problems presented in the production of drugs, accounted for 28.6%,and B-type drug quality problems,i.e drug quality problems involved in circulation and use of drugs, accounted for 71.4%.CONCLUSIONS:Drug quality data analysis report can objectively reflect the overall condition of hospital drug quality and the drug quality of the suppliers,thus it can be used as reference for hospital in optimizing future drug manufacturing enterprises and suppliers.

Objective:To demonstrate whether L carnitine can further improve the effect of recombinant human erythropoietin (rhEPO) in treatment of anemia. Methods: The patients were randomly divided into 3 groups, group A : L carnitine 1.0 g intravenously infused after every dialysis session; group B: rhEPO 50 150 IU/kg subcutaneously injected once or twice a week; group C: L carnitine and rhEPO given together. The serum albumin, hemoglobin(Hb) and hematocrit(Hct) were monitored for 6 months. Results: The albumin value in L carnitine group was significantly higher than that in rhEPO group ( P

The present study was aimed to investigate the influence of freeze-drying on the quality of polymerized human placenta hemoglobin (PolyPHb). The PolyPHb solution was freeze-drying under suitable conditions. Hemoglobin concentration, methemoglobin (MetHb) content, UV spectrum, Fe3 content, oxygen-carrying capacity, pH, the average molecular weight and its distribution, circular dichroism, oxygen equilibrium curve and other indicators were measured before and after freeze-drying. The appearance, residual water content, rehydration time of the lyophilized product were also evaluated. The results showed that there was no significant difference on all the indicators measured above, which indicated that freeze-drying process had no effect on the physical and chemical properties of PolyPHb, as well as on its biological activity. Therefore, the properties of PolyPHb were stable during this freeze-drying process and could be preserved after such freeze-drying process.
