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。

Hematoma Size in Deep Intracerebral Hemorrhage and its Correlation with Dot-Like Hemosiderin Spots on Gradient Echo T2*-Weighted MRI

BACKGROUND AND PURPOSE: Dot-like low intensity spots (dot-like hemosiderin spots: dotHSs) on gradient echo T2*-weighted MRI have been histologically diagnosed to represent old cerebral microbleeds associated with microangiopathies. They have also been correlated to the fragility of small vessels and the tendency to bleed. Therefore, a substantial number of dotHSs might be associated with a large-sized, deep intracerebral hematoma (ICH). On the other hand, dotHSs may reflect old microbleeds that did not enlarge to symptomatic size. METHODS: To investigate how dotHSs are related to the size (maximal diameter) of primary deep ICH, we analyzed the diameter and the number of dotHSs in 151 patients with deep ICH not associated with subarachnoid hemorrhage or intraventricular hemorrhage (75 males and 76 females, age ranged from 37 to 90 [65.7 +/- 11.3 years old] who were consecutively admitted to Hakodate Municipal Hospital. The hazard ratio (HR) for a maximal diameter of deep ICH < or =2 cm was estimated, using the number of dotHSs and risk factors for stroke. RESULTS: The number of dotHSs associated with the diameter < or =2 cm was 9.2 +/- 11.5, significantly larger than that with the diameter > or =2 cm (4.7 +/- 7.0, P= .012). Multivariate analysis revealed that a maximal diameter of deep ICH of < or =2 cm was found in patients with dotHS (HR, 3.7; 95% confidence interval [CI], 1.4-10.1; P= .009). CONCLUSION: Though small sample size limited the power of our analyses, these findings suggest that the number of dotHSs may be associated with a small diameter of deep ICH.     

超短波对大鼠坐骨神经损伤后脊髓内GAP-43和CGRP表达的影响

目的探讨超短波对坐骨神经损伤后大鼠脊髓中GAP-43和CGRP表达的影响。方法60只成年雌性SD大鼠制成右侧坐骨神经钳夹损伤模型，随机分为超短波治疗组和非治疗对照组。免疫荧光方法观察术后1周、2周、4周、8周和12周不同时间点两组大鼠脊髓中GAP-43和CGRP表达的动态变化规律。结果大鼠坐骨神经损伤后脊髓内GAP-43和CGRPmRNA表达增强。术后1、2、4和8周超短波治疗组的变化与对照组比较差异有统计学意义（P〈0．05），且GAP-43的表达在时间上早于对照组。结论超短波在早期能够明显增加GAP-43和CGRP的表达量，提示早期应用超短波治疗能够促进周围神经的     

Correction of frequency and phase variations induced by eddy currents in localized spectroscopy with multiple echo times.

As a consequence of the time-varying magnetic field induced by eddy currents, frequency drifting occurs when the sampling window of localized spectroscopy continuously shifts. The frequency drifting and the concomitant phase variations can severely affect spectroscopy results when data are acquired with multiple echo times (TEs), such as in the measurement of glutamate (Glu) concentration using the TE-averaged method. Specifically, the averaged spectra are further broadened and distorted in the presence of residual eddy currents, and editing of the coupled spins of Glu C4 protons is affected, resulting in errors in the measured relative intensity ratio. Postacquisition correction using unsuppressed water as reference can effectively minimize this detrimental effect, as manifested by the significantly enhanced signal intensity. Also, it is demonstrated that the methyl signals of creatine (Cr) at 3.0 ppm and choline (Cho) at 3.2 ppm can be used as internal references in finding frequency and phase disparities between different TEs.
