Reform of the property right system in medical institutions is an important part of Chinas health reform. It is closely related to the reform of the health investment system, the operating mechanism of medical institutions, regional health planning, the structural readjustment of health services, and the health management system. For this reason, the paper offers an account of the motive, objective, major forms, place and functions of the reform of the property right system in medical institutions as well as some other issues worthy of attention.

To observe the effects of paeoniflorin and total flavones extracted from Qixue Bingzhi Recipe on proliferation of vascular smooth muscle cells (VSMCs) cultured in endothelial cell conditioned medium (EC-CM) induced by oxidized low-density lipoprotein (ox-LDL) and the expressions of platelet-derived growth factor and its receptor genes.

A series of new coumarin-based benzotriazole derivatives were successfully synthesized via a multi-step sequence of cyclization, etherification and N-alkylation, and were confirmed by 1H NMR, IR, MS spectra as well as elemental analyses. All these synthesized coumarin compounds were evaluated for in vitro antimicrobial activities against four Gram-positive bacteria, four Gram-negative bacteria and three fungi by two fold serial dilution technique. The bioactive assay showed that all these prepared coumarin benzotriazoles could inhibit the growth of the tested bacterial and fungal strains. Title compounds 11a-11e and 13a-13c were more active than chloromycin on Proteus vulgaris ATCC 6896. Coumarin benzotriazoles 11a and 11b displayed comparable antibacterial efficacy against Staphylococcus aureus ATCC 25923 and Micrococcus luteus ATCC 4698 in comparison with reference drug chloromycin. Compared to fluconazole, compounds 11a-11d displayed stronger inhibition on Aspergillus fumigatus ATCC 96918. Moreover, coumarin-based benzotriazoles in combination with antibacterial chloromycin or antifungal fluconazole, showed notable antimicrobial efficacy with less dosage and broader antimicrobial spectrum. More importantly, fluconazole-insensitive A. fumigatus and methicillin-resistant Staphylococcus aureus N 315 (MRSA) were sensitive to these combined drugs.

Objective:To check RNA binding protein QKI-5's expression level in breast cancer cells and inhibiting effect on cancer cell proliferation.Methods:QKI-5's expression level was checked in different breast cancer cells by Western blotting,cancer cells of overexpressed QKI-5 gene could be stabilized by slow virus infection construction,MTT and FCM were used to check cell period to express QKI-5's influence on cell proliferation and period.Results:MCF-7 cells have relatively low QKI-5 expression level in three breast cancer cells,MTT experiment result has obvious reduced influence on QKI-5's expression of MCF-7 cell proliferation P＜0.05,mean-while,cell period inspection shows that overexpressed QKI-5's MCF-7 cells have obvious G1 retardant,cells in S and G2/M periods are reduced.Conclusion:High expression of QKI-5'in breast cancer could cause slow cell proliferation by inhibiting cancer cell period,hence causing limited tumor growth.

Objective To compare distribution and antimicrobial resistance of methicillin-sensitive Staphylococcus aureus(MSSA)and methicillin-resistant Staphylococcusaureus(MRSA)in hospitalized children,and provide refer-ence for empirical use of antimicrobial agents.Methods Isolation and clinical data of Staphylococcus aureus (S. aureus)from hospitalized children in a hospital during 2011-2015 were analyzed retrospectively,distribution and antimicrobial resistance between MSSA and MRSA were compared.Results A total of 919 strains of S.aureus were isolated,632(68.77% )of which were MSSA,287(31.23%)were MRSA.65.03% of MSSA infection and 64.11% of MRSA infection were in children aged 29 day-1 year old.80.38% of MSSA and 79.09% of MRSA were isolated from sputum specimen.MSSA and MRSA were mainly distributed in department of pediatric respiratory medicine(50.73%,45.89% respectively)and department of pediatric neurology(22.98%,26.84% respectively). Resistance rates of MSSA to antimicrobial agents were<20.00% except penicillin and erythromycin;resistance rates of MRSA to penicillin,oxacillin,erythromycin,and clindamycin were all>40.00%;resistance rates of MR-SA to tetracycline,erythromycin,clindamycin,levofloxacin,ciprofloxacin,moxifloxacin,nitrofurantoin,and ri-fampin were all higher than MSSA.Conclusion MSSA is main S.aureus isolated from hospitalized children,in-fants under 1 year of age are the main population,the main distribution departments of MSSA and MRSA from re-spiratory tract specimen are similar,antimicrobial resistance of MRSA is generally higher than that of MSSA.
