人力资源战略在医院管理中的运用及价值探讨

人力资源是医院最重要的资源,随着国内医疗市场的逐步开放和"三医"联动医药卫生体制改革的实施,医院之间的竞争愈加表现为人才的竞争,作为医院的高层管理者在战略决策管理中如何通过合理的人才战略和管理机制,吸引、培养、留下更多的人才并最大程度地调动他们的积极性和创造性显得十分重要.本文重点阐述了医院实施人力资源战略管理的方法,认为个人目标与组织目标保持高度一致,设计合理、灵活、富有激励的绩效考核办法是医院人力资源战略管理的关键所在.

脑血流和灌注储备能力评价在有症状颅内动脉狭窄诊治中的价值

在有症状颅内动脉狭窄患者的脑血流和灌注储备能力尚未明确之前，仅根据患者的临床症状和动脉狭窄程度进行手术干预具有相当的盲目性。脑血流和灌注是评价是否存在脑缺血的最直接证据。由于侧支循环和脑血管本身储备能力，颅内血管狭窄和（或）血流速度下降等并不一定表明该血管供血区脑灌注下降。文章阐述了脑血流和灌注储备能力评价在有症状颅内动脉狭窄患者诊治中的价值。     

Diplotypes of the human serotonin 1B receptor promoter predict growth hormone responses to sumatriptan in abstinent alcohol-dependent men.

BACKGROUND: Some studies have associated alcohol dependence (AD) with the human serotonin (5-HT)(1B) receptor (HTR1B). This investigation explored the functional responsivity of HTR1B in abstinent AD men using a sumatriptan challenge, while measuring genetic heterogeneity in the HTR1B promoter. METHODS: Abstinent AD men (n = 27) and abstinent men without any alcohol use disorder (n = 19) were administered 6 mg of sumatriptan succinate, subcutaneously. Plasma samples collected over the following 2 hours were assayed for growth hormone (GH) concentrations. His DNA was genotyped for the A-161T and T-261G polymorphisms of the HTR1B promoter and diplotypes determined. RESULTS: Integrated GH responses were predicted by interactions of AD and promoter diplotypes, as well as subject ethnicity. The final model accounted for nearly 35% of the variance in GH responses. Post hoc evaluation revealed that AD was associated with a blunting of GH secretion only among individuals with the most common HTR1B diplotype (TT/TT). CONCLUSIONS: A blunting of GH responses in abstinent AD men was observed only among those with the most common HTR1B promoter diplotype. Less common promoter diplotypes appeared protective. Controlling for genetic background is a useful augmentation of case-control pharmacological challenge strategies designed to elucidate the psychobiology of AD and other complex disorders.     

Engineering angiogenesis following spinal cord injury: a coculture of neural progenitor and endothelial cells in a degradable polymer implant leads to an increase in vessel density and formation of the blood–spinal cord barrier

Angiogenesis precedes recovery following spinal cord injury and its extent correlates with neural regeneration, suggesting that angiogenesis may play a role in repair. An important precondition for studying the role of angiogenesis is the ability to induce it in a controlled manner. Previously, we showed that a coculture of endothelial cells (ECs) and neural progenitor cells (NPCs) promoted the formation of stable tubes in vitro and stable, functional vascular networks in vivo in a subcutaneous model. We sought to test whether a similar coculture would lead to the formation of stable functional vessels in the spinal cord following injury. We created microvascular networks in a biodegradable two-component implant system and tested the ability of the coculture or controls (lesion control, implant alone, implant + ECs or implant + NPCs) to promote angiogenesis in a rat hemisection model of spinal cord injury. The coculture implant led to a fourfold increase in functional vessels compared with the lesion control, implant alone or implant + NPCs groups and a twofold increase in functional vessels over the implant + ECs group. Furthermore, half of the vessels in the coculture implant exhibited positive staining for the endothelial barrier antigen, a marker for the formation of the blood–spinal cord barrier. No other groups have shown positive staining for the blood–spinal cord barrier in the injury epicenter. This work provides a novel method to induce angiogenesis following spinal cord injury and a foundation for studying its role in repair.
