社区护理工作绩效评价体系的建立与实践

目的为了探索一套适合我国社区卫生服务机构持续健康发展的护理管理模式，以提高社区护理管理效应。通过专家评定法以及全体护理人员讨论的方法，给予每项护理工作以适当的权重，以此建立社区护理工作绩效量化评价体系，并组织实施。实施后，在社区护理工作方面形成了良好的管理导向，建立了有效的激励机制，提高了护理工作质量、效率和效益。因此，可以认为在社区护理实施工作绩效量化评价体系，是值得推广的一项举措。     

从天价医药费事件折射出当前我国医疗机构存在的问题

目前，我国许多医院的医疗卫生工作人员在为患者进行医疗卫生服务的过程中，为了医院和个人的经济利益，存在着过度医疗消费现象。最典型的是哈尔滨医科大学第二附属医院发生的天价医药费事件。导致这种现象出现的原因是由于法律的不健全、制度的不完善等而导致的监督力度不够，加之有些医务工作者在经济利益的驱使下使自己的职业道德滑坡，从而导致了老百姓看病贵现象的出现。     

Cerebral autoregulation is preserved in multiple system atrophy: A transcranial Doppler study.

Patients with multiple system atrophy (MSA) present large changes in blood pressure (BP) due to autonomic disturbances. We analyzed how this change may influence dynamic cerebral autoregulation (DCA). Simultaneous recordings of arterial BP (Finapres) and middle cerebral artery (MCA) blood flow velocity (BFV) (transcranial Doppler) were performed in 10 patients with MSA (61 +/- 12 yr of age) and 12 healthy volunteers (61 +/- 11 yr of age): cerebral BFV response to oscillations in mean BP was studied in the supine position by cross-spectral analysis of mean BP and mean MCA BFV. The DCA was also studied during the decrease in BP the first seconds when standing up from a sitting position by the assessment of the cerebrovascular resistance index (CR; mean BP/mean MCA BFV ratio). The MCA BFV/BP cross-spectral analysis showed a phase for the mid-frequency band (0.07-0.2 Hz) significantly larger in MSA, suggesting more active autoregulation in response to larger changes in BP. Changes in CR reflecting the rate of autoregulation, when standing did not differ between the two groups. These data suggest that dynamic cerebral autoregulation is preserved in MSA.     

促血小板生成素对预测脑瘫高危儿的意义

目的探讨缺氧缺血性脑病(hypoxia-ischem ia encephalopathy,H IE)胎儿和H IE新生儿血清中促血小板生成素(Thrombopoietin,TPO)水平与脑损伤的关系,为脑瘫(cerebral palsy,CP)高危儿人群进行早期干预提供监测手段。方法收集23例H IE胎儿和34例H IE新生儿血清以及25例正常胎儿和30例正常新生儿血清,34例H IE新生儿包括11例轻度H IE,8例中度H IE和15例重度H IE。采用双抗体夹心ABC-ELISA法检测H IE胎儿组和轻、中、重H IE新生儿组血清中TPO的水平,并与正常胎儿组和正常新生儿组比较。结果H IE胎儿组和H IE新生儿组TPO分别高于正常胎儿组和正常新生儿组(分别P<0.01,P<0.01),重度H IE组TPO低于轻度H IE组(P<0.05)。结论血清TPO水平与H IE所致脑损伤严重程度有关。脐血TPO检测可为脑瘫高危儿人群进行早期干预提供监测手段。     

An experimentally supported, mathematical explanation of the gas chromatographic elution behaviour of the long-chain carbon members of the homologous series

By substituting the saturated vapour phase tension of the pure normal hydrocarbons described by the Clausius-Clapeyron law into the accepted expression of the specific retention volume (V_g,T), a theoretically coherent and relatively simple mathematical evidence of the elution behaviour of the homologous members has been deduced. It gives exponential retention time dependence on carbon number for isothermal, and nearly equidistant (i.e., approximately linear retention-time dependence on carbon number) elution for linear temperature programmed gas chromatographic runs. The final equations are in close correlation with the experimental results. Special emphasis is placed on the fact that a good approximation—not strict physical laws—have been found.     

Pharmacokinetic profile of tamsulosin OCAS

The tamsulosin oral‐controlled absorption system (OCAS®) is a new tablet formulation of the α₁‐adrenoceptor (α₁‐AR) antagonist tamsulosin, which is used for treating lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). The tablet uses the OCAS technology, which was specifically designed to give a more continuous 24‐h release of tamsulosin, resulting in a more consistent and continuous 24‐h plasma concentration, a lower maximum plasma concentration (C_max) and an independence of pharmacokinetics (PKs) on food intake. It was expected that the improved PK profile would translate into a better control of day‐ and night‐time symptoms of BPH and a lower risk of adverse events. Phase I PK studies showed that tamsulosin OCAS indeed has a flattened PK profile with a lower C_max and a more stable and consistent 24‐h concentration of tamsulosin, independent of food intake, compared to conventional tamsulosin. A study combining γ‐scintigraphy and PK analysis of blood samples confirmed that the improved PK profile of tamsulosin OCAS is attributed to the tablet being consistently and continuously released throughout the entire gastrointestinal tract, including the colon.

Primary angiitis of the central nervous system: MRI features and clinical presentation

We report the MRI features in a series of four patients with primary angiitis of the central nervous system (PACNS). Based on MRI features, clinical presentation, paraclinical investigations and laboratory tests, including cerebrospinal fluid (CSF) analysis, various differentials were considered. In two patients with MRI findings of cortical, subcortical and deep white matter lesions, lack of mass effect, focal areas of bleed and heterogeneous parenchymal, leptomeningeal or pial enhancement and a normal magnetic resonance angiography, a differential diagnosis of primary angiitis of the CNS was also considered. In all patients, an open brain biopsy was advised to establish a definitive diagnosis of PACNS. Here, we briefly discuss the MRI features, correlation with clinical presentation and paraclinical parameters for the diagnosis of this entity. We also briefly review the literature.
