按资源成本支付医生服务费的研究

国外医学（卫生经济分册） 1991年第4期8卷 39-41页

作者： hsiao wc 施荣根

美国为了有效地控制老年医疗保险制度费用的上涨,研制了一种新的付费方法,即“按资源投入为基准的相对价值费用率”(Resource Based Related Value,RBRVS)方案。本文叙述了该方案的制定过程及其影响。

由于1980年全面的经济改革,中国农村的卫生保健制度正在发生迅速的转变。本文研讨中国农村合作医疗制度的演变,目的在于总结一些不仅对于第三世界而且对发达国家也有价值的经验教训。中国农村保健制度正在发生变化并不是事先计划的,而是由于经济改革对保健的组织、资金和服务的影响的结果。这种影响有些是直接的,有些是间接的,是出乎预料的。因为农村经济改革,集体对合作医疗提供的资金和群众的支持已经减少。享受这项保健制度的农村人口下降50％左右。据1979

The Sharpless asymmetric epoxidation of 1 was carried out to give the (1S,2S)-4 in 33% yield, which was protodesilylated giving (-)-5 with 50% ee. The steric effect of phenyl group on silicon upon the rate and ee of the reaction was observed. The possibility of kinetic resolution of racemic silanol under the Sharpless reaction condition was examined.

Chronic heart failure （CHF） is a complex clinical syndrome resulting from inefficient myocardial pumping, and is characterised by a typical progressively deteriorating trajectory punctuated by serious episodes of acute disease *** prevalence of hospital admission has been reported.[2] However, around 40% of hospital admissions was avoidable if patients demonstrate consistent self-care.

SINCE Alvarez first used iridium anomaly to explain the Cretaceous-Tertiary impact eventand mass extinction, more than 70 sites of iridium-nickel anomalies have been found. The Per-mian-Triassic boundary extinction is more prominent than that of the *** leads us to make research on whether similar events happened during that period.

Objective: A variety of ion channels have been implicated in breast cancer proliferation and *** K+(Kv) channels not only cause repolarization in excitable cells,but are also involved in multiple cellular functions in non-excitable *** this study we investigated the role of Kv channels in migration of BT474 breast cancer ***: Transwell technique was used to separate migratory cells from non-migratory ones and these two groups of cells were subject to electrophysiological examinations and microfluorimetric measurements for cytosolic *** migration was examined in the absence or presence of Kv channel ***: When compared with non-migratory cells,migratory cells had much higher Kv current densities,but rather unexpectedly,more depolarized membrane potential and reduced *** transcriptasepolymerase chain reaction(RT-PCR) analysis revealed the presence of Kv1.1,Kv1.3,Kv1.5,Kv2.1,Kv3.3,Kv3.4 and Kv4.3 *** migration was markedly inhibited by tetraethylammonium(TEA),a delayed rectifier Kv channel blocker,but not by 4-aminopyridine,an A-type Kv channel ***: Taken together,our results show that increased Kv channel expression played a role in BT474 cell migration,and Kv channels could be considered as biomarkers or potential therapeutic targets for breast cancer *** mechanism(s) by which Kv channels enhanced migration appeared unrelated to membrane hyperpolarization and Cainflux.
