1.Regional longitudinal healthcare alliances in China: development and policy suggestions
Chinese Journal of Hospital Administration 2017;33(8):561-564
The development status of regional longitudinal healthcare alliances in China was analyzed in the paper.As found by the authors, such existing problems as the healthcare administrative system and fiscal input system, the crisis of confidence on primary medical institutions, poor information platforms, and limited means of medical insurance payment, constitute roadblocks for healthcare alliances to play their roles.Proposals of the paper cover such grounds as follows: the government to make a top-down design and a longitudinal and integrated healthcare system can be built;to build a corporate structure for the alliances, with greater fiscal support;to reform the medical insurance payment practice for integrating interests of medical associations;to clarify the responsibilities of tertiary hospitals, for building a win-win mechanism among stakeholders, and improving the information sharing platform.These measures, if in place, can propel the healthy development of healthcare alliances in China.

OBJECTIVETo study the chemical constituents in fruit of Alpinia oxyphylla and their cytotoxicities on cancer cell lines.
METHODCompounds were isolated and purified by various column chromatographic methods. Their structures were determined by physico-chemical properties and spectral analyses. Compound cytotoxicity was assessed by the sulforhodamine B (SRB) assay.
RESULTEight compounds were obtained from Me2CO-H2O (70%) extract of the fruit of A. oxyphylla and their structures were identified as: (9E)-humulene-2, 3; 6, 7-diepoxide (1), 3(12), 7(13), 9(E)-humulatriene-2, 6-diol (2), (-)-oplopanone (3), yakuchinone A (4), yakuchinone B (5), tectochrysin (6), isovanillin (7), (2E, 4E)-6-hydroxy-2, 6-dimethylhepta-2, 4-dienal (8), and the cytotoxicities of compounds 1, 3-5 on cancer cell lines, A549, HT-29 and SGC-7901, were also investigated.
CONCLUSIONCompounds 1-3, 7, 8 were isolated for the first time from this genus and compounds 1, 3-5 exhibited no cytotoxicity against three cancer cell lines at a concentration of 10 mg x L(-1).
