1996 outlook: systems, for-profit chains, medical groups, religious healthcare, managed care, post-acute care, finance, purchasing, info systems, labor, legal, construction

It's put-up-or-shut-up time for healthcare providers in 1996. Two years ago, everyone talked about fixing the healthcare system. Not much happened. Last year, providers and politicians concentrated on squeezing medical costs. According to some of Modern Healthcare's key beat reports, this year it's back to the basics of running a business.     

机体代谢变化与晕船的关系

目的　探讨晕船对血清铁、铜、锌、尿素氮、肌酐、乳酸脱氢酶、肌酸激酶的影响。方法　以 3 0名 2 0～ 2 2岁男学员为研究对象 ,测定出航前与晕船发生后的血清铁、铜、锌和尿素氮、肌酐、乳酸脱氢酶、肌酸激酶的变化。结果　出航前、后受试者血清锌、铁、尿素氮、肌酐的含量分别为 (10 60± 0 3 3 ) μmol/L ,(2 0 48± 0 96) μmol/L ,(4 2 9±0 18)mmol/L ,(88 13± 3 0 3 ) μmol/L和 (11 98± 0 44 ) μmol/L ,(9 68± 0 66) μmol/L ,(7 11± 0 3 0 )mmol/L ,(10 8 5 9± 3 90 ) μmol/L ,差异有显著性 (P <0 0 1) ;血清铜、乳酸脱氢酶、肌酸激酶在航行前后分别为 (14 2 9± 1 10 ) μmol/L、(12 9 3 3± 4 12 )U/L、(2 17 13± 40 0 4)U/L和 (13 67± 0 5 6) μmol/L、(146 63± 9 2 2 )U/L、(148 0 7± 9 94)U/L ,无显著性差异。结论　晕船对血清微量元素和尿素氮、肌酐含量有显著影响 ,表现为血清锌、尿素氮、肌酐显著升高 ,血清铁显著下降 ,而对血清铜、乳酸脱氢酶、肌酸激酶无明显影响
