Multidrug resistance (MDR) remains the major obstacle to the success of clinical cancer chemotherapy. P-glycoprotein (P-gp), encoded by the MDR1, is an important part with complex mechanisms associated with the MDR. In order to overcome the MDR of tumors, we in the present experimental design incorporated small interfering RNA (siRNA) targeting MDR1 gene and anticancer drug paclitaxel (PTX) into the solid lipid nanoparticles (SLNs) to achieve the combinational therapeutic effects of genetherapy and chemotherapy. In this study, siRNA-PTX-SLNs were successfully prepared. The cytotoxicity of blank SLNs and siRNA-PTX-SLNs in MCF-7 cells and MCF-7/ADR cells were detected by MTT; and the uptake efficiency of PTX in MCF-7/ADR cells were detected via HPLC method; quantitative real-time PCR and flow cytometry were performed to investigate the silencing effect of siRNA-PTX- SLNs on MDR1 gene in MCF-7/ADR cells. The results showed that PTX loaded SLNs could significantly inhibit the growth of tumor cells, and more importantly, the MDR tumor cells treated with siRNA-PTX-SLNs showed the lowest viability. HPLC study showed that SLNs could enhance the cellular uptake for PTX. Meanwhile, siRNA delivered by SLNs significantly decreased the P-gp expression in MDR tumor cells, thus increased the cellular accumulation of rhodamine123 as a P-gp substrate. In conclusion, the MDR1 gene could be silenced by siRNA-PTX-SLNs, which could promote the growth inhibition efficiency of PTX on tumor cells, leading to synergetic effect on MDR tumor therapy.

OBJECTIVE:To systematically review the current situation and facing problems of hierarchical diagnosis and treat-ment in China,and provide basis for nation health-related decisions. METHODS:Using"hierarchical diagnosis and treatment"as keyword,relevant literatures in CNKI,VIP database,and Wanfang database from building to Jun. 2016 were retrieved. Study for current situation of hierarchical diagnosis and treatment in China was comprehensively collected,and systematical review was con-ducted from aspects of outcome evaluation indicators and facing problems. RESULTS:Totally 23 studies were included,in which, 18 were investigative studies,3 were retrospective/investigative studies,1 was retrospective study,and 1 was randomized con-trolled study. In the outcome evaluation indicators,9 took awareness of hierarchical diagnosis and treatment as review indicators, showing that the public had poor awareness;7 took the current situation as review indicator,showing that the overall current situa-tion was unsatisfactory;3 took human resources as review indicator,showing that human resources in primary medical institutions were not ideal;3 took satisfactory degree as review indicator,showing that the public were generally satisfied with hierarchical di-agnosis;2 took the implementation model as review indicator,showing that the current model had been able to promote hierarchi-cal diagnosis and treatment;2 took medical cost as review indicator,showing that individuals paid higher. In the facing problems, 19 studies suggested the imperfect systems for hierarchical diagnosis and treatment,16 suggested that primary medical treatment was limited in capability,7 suggested that patients still preferred big hospitals to primary medical institutions,and 7 suggested that it lacked publicity. CONCLUSIONS:The current situation of hierarchical diagnosis and treatment is certainly not ideal but still fac-ing many problems in China. Improving the levels in primary institutions,hierarchical diagnosis and treatment system and patients' willingness to primary medical institutions,and increasing its publicity can deeply promote the implementation of hierarchical diag-nosis and treatment and provide objective and valuable reference for health decision-making.

A series of poly (lacticacid-co-glycolicacid)-poly(ethylene glycol) (PLGA-PEG, PELGA) block copolymers and poly (ethylene glycol)-poly (lacticacid-co-glycolicacid)-poly (ethylene-glycol) (PELGE) was synthesized by ring-opening polymerization. PELGA nanoparticles and PELGE nanoparticles were prepared using the emulsion-solvent evaporation technique (O/W). To study the behavior and mechanism of the degradation of PELGA-NP and PELGA-NP, we determined the lactic acids by UV spectrophotometry. The method confirmed that degradation was much faster for polymers with a decrease in the LA content of the polymers or an increase in the PEG content of the polymers.

OBJECTIVE:To evaluate the indicators of ADR reporting by medical institutions in China. METHODS:The indicators of ADR reporting by medical institutions in China were presented primarily by 8 pharmacy experts with focus group interview method. System assessment method was used for evidence-based analysis of primary ADR indicators. Delphi method was used to confirm the requirement,calculation formula,definition,evaluation meaning and reference value of ADR indicators. The reliability was assessed. RESULTS:Primary indicators included the rate of ADR reporting,the rate of qualified ADR,constituent ratio of severe and new ADR. A total of 30 literatures were included(15 documents of management standard,15 literature research)in system evaluation,all of which indicated the necessity and requirement of ADR reporting. But the calculation formula, definition and evaluation meaning of ADR indicators were not mentioned. By investigation with Delphi method,the range of reference value was confirmed as follows that the rate of ADR reporting was≥0.01%;the rate of qualified ADR was≥90%;the constituent ratio of severe and new ADR was≥1%. The evaluation result was reliable. CONCLUSIONS:The indicators of ADR reporting and reference lower limit value can urge medical and health institutions to report ADR actively,improve the quality of ADR reporting and strengthen the attention of medical and health institutions to severe and new ADR.
