OBJECTIVE:To facilitate the construction of Chinese pharmaceutical profession associations. METHODS: We analyzed the current situation and problems existing in Chinese pharmaceutical profession association as well as the developmental experience of foreign pharmaceutical associations then put forward suggestions for the development of pharmaceutical profession associations in China. RESULTS & CONCLUSIONS: The sound development of pharmaceutical profession associations calls for the cooperated efforts of government, profession association and pharmaceutical enterprises, meanwhile its function as bridge and tie between pharmaceutical enterprises and government should be brought into full play.

OBJECTIVE:To provide references for Chinese drug distribution reform.METHODS:The drug distribution model in USA was briefly introduced and compared with that in China.The difficulties and orientations in Chinese drug distribution reform were put forward.RESULTS &CONCLUSIONS:Drug distribution reform should be carried out cautiously.Our government should deal well with the relationships between different interested parties and set up a reimbursement mechanism in medical institutions in order to facilitate the reform.

OBJECTIVE:To further perfect the discipline theory of pharmaceutical administration in China.METHODS:The processes and methods of the discipline theory construction of pharmaceutical administration was studied by deductive theory and‘taking root’theory.RESULTS&CONCLUSION:The pharmaceutical administration theory is characterized by diverse and empirical,to make it improved,more research work needs to be done.

This article introduces the classifications of medical devices by FDA and EU and compares them with the situation in China. Towards the problems found, several reasonable advices are put forward.

Objective To investigate the effects of inhibitor of growth 4(ING4)on the proliferation,migration and the expression of angiogenesis related factors such as VEGF,MMP-2,MMP-9 in endothelial cells. Methods Human umbilical vein endothelial cells(HUVECs)were cultured in vitro;ING4 plasmid and siRNA were constructed and transfected to HUVECs;the proliferation of HUVECs was evaluated by MTT assay;the ability of migration was evaluated by Transwell assay;real-time PCR and Western blotting were used to determine the expression of mRNA and pro-tein of angiogenesis related factors such as VEGF,MMP-2,and MMP-9. Results MTT and Transwell assay showed that ING4 has the ability to inhibit the proliferation and migration of HUVECs,and the results of real-time PCR and Western blotting proved that ING4 can inhibit the expres-sion of angiogenesis related factors such as VEGF,MMP-2,and MMP-9. Conclusion ING4 can inhibit the proliferation and migration of HU-VECs,down-regulate the expression of angiogenesis related factors such as VEGF,MMP-2,MMP-9,and inhibit angiogenesis.

Hospital acquired infection (HAI) is one of the common complications of hospitalized patients and poses a serious threat to public health worldwide, which causes an exacerbation, prolonged hospitalization and increased medical costs. Because of higher illness severity and more invasive operations, patients in neurosurgical intensive critical unit (NICU) are more susceptible to HAI such as hospital acquired pneumonia (HAP) and surgical site infection (SSI), leading to theincrease of mortality. Therefore, the prevention and treatment of HAI is an important challenge during the treatment of diseases in NICU. In this paper, we summarized the common types, pathogenic characteristics, prevention measures and antimicrobial treatment of HAI in NICU, aiming to provide ideas and reference on HAI treatment for medical personnel in NICU.

OBJECTIVE:To study the consistency policies of generic drugs in China,America and Japan comparatively,and provide reference for perfecting quality and efficacy consistency evaluation of generic drugs in China. METHODS:Generic drugConsistency evaluationQuality evaluationDESIwere used as keywords to search the related literatures or information of ge-neric drugs published or reported in CNKI,Web of Science,Elsevier,Springer database and USA FDA website during Jan. 1st, 1950-Jun. 30th,2016. And comparative analysis was conducted for the historical background,evaluation methods and policy influ-ences of consistency policies of generic drugs in China,America and Japan. RESULTS:There were differences in the historical background,evaluation methods,major participants and policy influences of consistency policies of generic drugs in China,Ameri-ca and Japan. The evaluation for generic drugs in USA was reevaluation of the drugs effectiveness under the history of drug registra-tion regulation was imperfect. With experts'review,it was evaluated based on FDA,enterprises,scientific literature evidence and experts review. Main evaluation method was in vitro dissolution test in Japan. The consistency evaluation of generic drug in China focused on the generic drug marketing authorization,mainly using in vivo bioequivalence. And the standards of reference prepara-tions were from the basically similar drugs to the original drugs. CONCLUSIONS:Compared with innovation-based countries like America and Japan,the availability of reference preparations in China is low,and policy environment is more complex. China should further improve the laws and regulations,giving reasonable buffer period,considering the diversity of evaluation methods, exemptions in special circumstances and current situation of pharmaceutical industry,paying attention to the balance between techni-cal supervision and system supervision.

Objective To optimize the formulation of self-microemulsifying drug delivery systems containing tanshinone ⅡA(tanshinone ⅡA-SMEDDS) and assess the quality of tanshinone ⅡA-SMEDDS. Methods Pseudoternary phase diagrams were used to choose the oil,emulsifier,co-emulsifier,and their proportion in the formulation on the basis of the ability to form emulsions and regions. Then the self-emulsifying time,droplet and morphology,size distribution,?-potential,stability,and other aspects of the quality were evaluated. Results The formulation of tanshinone ⅡA-SMEDDS was as follows:ethyl oleate-Labrasol-PEG 400=10%:45%:45%,drug loading ratio was 2.25 mg/g. The self-microemulsifying time of tanshinone ⅡA-SMEDDS in 0.1 mol/L hydrochloric acid solution was less than 1 min,the emulsion drops were spherical shape with average particle size of (84.9?2.1) nm and the average ?-potential (-24.0?1.15) mV (n=3). So tanshinone ⅡA-SMEDDS was stable. Conclusion In this paper,the tanshinone ⅡA-SMEDDS has a good self-emulsifying performance. It is expected to further stabilize the preparation of tanshinone ⅡA self-microemulsifying agents.

OBJECTIVE:To put forward strategies to evolve the current drug bidding system.METHODS:The objective and efficacy of the drug bidding system was analyzed;and the reasons for the poor efficacy of the system were analyzed using the information asymmetry theory in economics,and the system was compared with its US counterpart.RESULTS & CONCLUSIONS:The drug bidding system in China should adopt such model in which the payers are chosen as agency and charge from the entrusting party.It is a systematic project to standardize drug circulation channels,reduce drug price and reduce the burden of patient,which can't be tackled by drug bidding system only.

OBJECTIVE:To compare between China and WHO the difference of the Essential Medicine List(EML).METHODS:The relation and differences between China and WHO were analyzed by comparing the background,the classification system and quantity of Essential Medicines.RESULTS & CONCLUSION:Chinese EML is based on WHO EML,and these two EMLs are congenetic.But there are some differences between China and WHO in classification system,quantity and content of Essential medicines.We should modify and issue EML according to the situation of our country by referring to WHO EML.
