Objective: To analyze the status and general trend of urban residents’ health equity and health performance. Methods:Adopting standardization of concentration index, the extended concentration index and health performance index. Results: Chronic disease and self-assessed health of urban residents in China gradually improved from 2007 to 2011, while disability of those people did not improve significantly. Health inequity exists among urban residents with different incomes. Chronic disease and disability are inclined to the poor while self-assessed health is inclined to the rich, but the unfair degree has decreased gradually by year; the self-assessed health and the health performance of chronic disease has been improved from the comprehensive health level and equity, the disability sustains serious condition. Conclusion: China’s new health care reform does not significantly improve the domestic urban residents’ health equity and health performance, the objective set of the health care reform in China should pay more attention to health equity.

A method was developed for purification of 20S proteasome (20S core particle, CP) by combining differential centrifugations with nondenaturing polyacrylamide gel electrophoresis (native-PAGE), irrespective of species origins of CPs. CP purified from human erythrocytes was subjected to proteomic analysis by two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), revealing 33 spots of subunit isoforms with different molecular weights and isoelectric points, more than 14 constituent subunits. Furthermore, other four CPs were purified from yeast, mouse liver, two pancreatic cancer cell lines SW1990 and PANC-1 using this method mentioned above, and subjected to proteasome heterogeneity analysis by native/SDS-PAGE (native/sodium dodecyl sulphate polyacrylamide gel electrophoresis), together with CP from erythrocytes. The method described acts as a rapid and effective tool for CP isolations, and the results obtained may be served as a footstone for the investigations of species-dependent proteasome heterogeneity.

Object:The paper aims to analyze Taiwanese experience in pharmaceutical procurement, pharma-ceutical benefits and reimbursement schedule, and make references for the Mainland China. Methods:Through read-ing and analyzing the Taiwanese government policy and the literature published to find out the pharmaceutical pro-curement measures, different medicines’ pricing strategy and its reimbursement mode compared with the Mainland China. Results: Hospitals can purchase medicines based on their own needs, and the purchase price was formed through negotiating with providers and buyers. It has been found that Taiwan only controls the medicines reimburse-ment prices. The international reference pricing is adopted for new medicines, and the originators, bioequivalence/bioavailability generic medicines and general generics reimbursement prices are very high at international reference prices, and need to be weakened in order to fit the requirements. Moreover, the medicine quality is one of the stand-ards considered in case of making decisions on the reimbursement prices. In addition, the reimbursement price is as-sociated with procurement price. When the spread is larger than 30%, the government will adjust the reimbursement to fill the gap. Conclusions: Through the system design and adjustment, the Taiwanese Government have set up a better procurement and reimbursement co-ordination in the pharmaceutical segment, and formed the reasonable prices for the case. The Taiwanese experience can be taken as a reference for the mainland China to refine its procurement reforms and reimbursement policy.
