| 1 | Triptolide-loaded microemulsion-based hydrogels: physical properties and percutaneous permeability显示文摘Triptolide is a diterpenoid compound that inhibits the inflammation of rheumatoid arthritis(RA).However,the use of triptolide is limited due to its strong gastrointestinal toxicity.The purpose of this work was to develop a transdermal delivery system for triptolide to reduce this toxicity.A microemulsion-based hydrogel(MBH)was prepared from the combination of Gemseal 40-oleic acid as oil phase,Tween 80-labrasol as surfactant,anhydrous ethanol as co-surfactant,water as aqueous phase and Poloxamer 407 as hydrogel matrix.Rheological measurements,environmental scanning electron microscopy(ESEM)and transdermal experiments in vitro were used to characterize triptolide-loaded and blank MBH preparations.The effects of Poloxamer 407 and triptolide on the rheological properties and microstructures of the MBH were determined.Transparent and homogeneous MBH could only be formed when the concentration of Poloxamer 407 in the selected O/W microemulsion was in the range of 14.0–16.0%(w/w).When the concentration of Poloxamer 407 increased,the rheological properties such as the yield stresses(sy),storage and loss moduli(G′,G″)of the formulations increased,and the network structures became more compact.The addition of triptolide did not change the interconnected network structures of the MBH preparations.MBH preparations afford a better sustained release profile when compared to microemulsions,a finding confirmed by an in vitro permeation test in mice.MBH appears to be a promising vehicle for transdermal delivery of triptolide. | Lihua Chen Xiaoting Zhao Jia Cai Yongmei Guan Sen Wang Hongning Liu Weifeng Zhu Junsong Li | 2013 | Acta Pharmaceutica Sinica B2013，3，3： | 1 |
| 2 | Research on the Construction of Pharmacy Organization and the Development of Pharmaceutical Services in China’s Primary Medical and Health Institutions—Based on the Survey of 5 Provinces显示文摘Objective To explore the current situation and problems of the pharmacy organization and pharmaceutical services in primary medical and health institutions so as to provide a reference for improving relevant policies.Methods Multi-stage stratified random sampling was used to collect questionnaires from primary medical and health institutions in 5 provinces,and 102 questionnaires were distributed.Then Excel 2016 and IBM SPSS 21.0 software were applied for descriptive statistical analysis,chi-square test and multiple response analysis.Results and Conclusion A total of 92 primary medical and health institutions participated in the survey,and 92 valid questionnaires were recovered.The survey shows that 54.1%of the institutions have established more than 8 pharmaceutical administration regulations.63.5%and 31.8%of the institutions have formulated pharmaceutical administration and pharmacotherapy team charters(or management systems).29.7%of institutions have pharmacy personnel in accordance with relevant regulations.The higher proportion of pharmacy services are prescription review and adjustment,medication guidance,collecting and reporting adverse reactions,medication errors and medication hazard information.Primary medical and health institutions still need to further improve their pharmaceutical administration system,organizational structure,pharmacy professional training and clinical pharmacy service. | Cai Hongning Sun Lihua | 2021 | Asian Journal of Social Pharmacy2021，16，1： | 0 |
