??OBJECTIVE To evaluate the efficacy, safety and economy of tramadol and hydromorphone combined with flurbiprofen axetil in the treatment of PCIA for postoperative cesarean through the empirical study, optimize the drug treatment program and provide certain evidence-based medicine and pharmacoeconomics basis for clinical use of drugs. METHODS Included 240 cases of maternal, these maternal need to use PCIA for postoperative analgesia and meet the inclusion and exclusion criteria. The maternal samples included in the study were divided into two groups: tramadol(tramadol 2 mg ??kg^-1+flurbiprofen axetil 5 mg??kg^-1) and hydromorphone(hydromorphone 0.04 mg ??kg^-1+flurbiprofen axetil 5 mg??kg^-1). The efficacy index, safety index and cost index of the two groups were observed. The effectiveness, adverse reactions and cost data were collected. Statistical analysis and cost effectiveness analysis were used to evaluate the economic effects of the two groups. RESULTS The analgesic effect of tramadol group was same as the hydromorphone group, but the total cost of analgesia in tramadol group was lower than that in hydromorphone group, the results of the minimum cost analysis showed that the tramadol regimen was superior and the results were stable. CONCLUSION The PCIA regimen of tramadol group is superior to that of the hydromorphone group, considering the efficacy, safety and economy.

??OBJECTIVE To establish a capillary zone electrophoresis(CZE)-based method for charge heterogeneity analysis of IgG2 monoclonal antibody. METHODS The concentrations of TETA and EACA, pH of separation buffer and temperature of capillary were optimized, to obtain a method which can efficiently separate the charge variants of IgG2 mabs. The reproducibility and repeatability of the optimized CZE method were validated and a battery of mabs were evaluated. RESULTS The separation effect was significantly influenced by TETA/EACA concentration, pH and separation temperature. Through a series of optimization, a CZE method which showed good resolution and precision(RSD of area percentage was below 3.0% was established and the method parameters were as below: 400 mmol??L^-1 EACA/0.05% TETA, pH 6.2, separation under 30 kV voltage at 35 ??. This method was also suitable for IgG1 and IgG4 mabscharge heterogeneity analysis. Based on the specific electrophorogram and migration time, it could also be used as an identification method for monoclonal antibodies. CONCLUSION The optimized CZE method can efficiently separate the charge variants of IgG2 mabs and shows good precision and specificity, which can be used to analyze the charge heterogeneity and identification of monoclonal antibodies.
