连续性静脉-静脉血液滤过在老年多器官功能障碍中的应用

目的:观察连续性静脉-静脉血液滤过(CVVH)在一组老年多器官功能障碍(MODS)患者中应用的效果及安全性。方法:50例老年MODS患者患者分为A组和B组,A组27例接受CVVH治疗,B组23例接受普通透析,患者在治疗前后进行APACHE评分,并检测血钠、钾、氯、尿酸、碳酸氢盐、氧分压、二氧化碳分压和脑钠肽。结果:①治疗后,血电解质紊乱和酸碱失衡得到纠正,毒素明显下降,两组患者间无显著性差异。②与B组患者相比,A组患者治疗后,脑钠肽和二氧化碳分压明显下降,氧分压上升,APACHE评分明显降低。结论:与普通透析相比,CVVH除了能清除毒素和纠正电解质酸碱失衡以外,还能提高患者PO2、减轻CO2潴留,明显改善心肺功能效果,因此应用于老年MODS患者是安全有效的。

目的探讨ICU老年败血症的危险因素,致病菌的分布和耐药分析。方法回顾性分析2000年1月～2005年12月间经血培养和临床资料证实的21例老年败血症。结果有严重基础病与高危因素占95.84%(20/21)。高危因素包括介入性诊治、滥用抗药菌物、呼吸机的使用等;21例中G-菌9例(42.86%);G 菌9例(42.86%);真菌6例(28.57%)。细菌对常用抗菌药耐药严重。结论老年败血症病情危重,病死率高;G-菌有下降的趋势,但仍是老年败血症感染的主要病原菌,条件致病菌和真菌感染率明显增多;防治ICU老年败血症的关键在于及早治疗基础疾病,预防高危因素,减少耐药菌株的发生显得尤为重要。     

Immunohistochemical study of distribution of apolipoproteins E and D in human cerebral beta amyloid deposits

Several molecules are known to be closely associated with amyloid deposits in human brain. Among these, apolipoproteins such as apolipoproteins E (apo E) and J (apo J) have been found in two neuropathological hallmarks of Alzheimer's disease (AD) and cerebral amyloid angiopathy (CAA): senile plaques (SPs) and cerebrovascular amyloid. These apolipoproteins may be implicated in amyloid fibrillogenesis. Apo D is a multiligand-multifunctional glycoprotein present in SPs, as we previously reported. The aim of this work is to study the link between immunolocalization of apo E and apo D in AD and CAA brains. Both apolipoproteins were found in all types of SPs, but apo E was observed more often than apo D in mature plaques. Whereas apo E is always located overlapping the amyloid core, apo D seems to situate preferably around and near the amyloid. Immunohistochemistry revealed that these apolipoproteins behave differently in cerebral vessels. Apo E labeling in vessels appears mainly linked to amyloid deposits, whereas apo D shows a distribution almost opposite to that of apo E. This could be an indication of the different roles that each apolipoprotein plays in the pathogenesis of amyloid deposition.     

Determination of cadmium and zinc in Alzheimer's brain tissue using inductively coupled plasma mass spectrometry

In this work, brain tissue was taken from Alzheimer's Disease (AD) subjects (n=11), 'normal' subjects (n=10) and from subjects with senile involutive cortical changes (SICC) (n=6). Concentrations of Cd and Zn were determined in all samples, using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The brain tissue was selected and obtained from the Netherlands Brain Bank. Samples were taken in each case, from both hemispheres of the superior frontal gyrus, the superior parietal gyrus, the medial temporal gyrus, the hippocampus and the thalamus of the same brain.Cd which is known to have no essential role in the brain was found to follow, as expected, a lognormal distribution of concentrations in 'normal' subjects (Shapiro-Wilk's test (0.98) (p<0.18)). For the Alzheimer's Disease subjects and SICC subjects, the data tends to follow a lognormal distribution, rather than a normal distribution, but is still significantly different from it (Shapiro-Wilk's test (0.97) (p<0.03); (0.93) (p<0.0067), respectively)).In the case of Zn concentrations, the data tends to follow a normal distribution for the 'normal' subject group, even though the data is significantly different from it (Shapiro-Wilk's test (0.95) (p<0.001)). Whereas in the Alzheimer's Disease and SICC subject groups, the data follows a normal distribution (Shapiro-Wilk's test (0.98) (p<0.21); (0.97) (p<0.2002), respectively)).When comparing age-matched groups, for all regions and both hemispheres, no significant differences (p>0.1) for Cd were found between 'normals' and Alzheimer's Disease subjects and Alzheimer's Disease subjects and SICC but at a low level of significance, lower concentrations of Cd were found in the SICC group compared to the 'normals'. For all regions and both hemispheres, Zn was found to be significantly decreased in the Alzheimer's Disease group, compared to the 'normal' and SICC groups. Zn concentrations were also found to be significantly decreased in the 'normals' compared to the SICC group.It is also of interest that Cd negatively correlates with the scale of tangles in both 'normals' (p<0.001) and Alzheimer's Disease subjects (p<0.01). In the SICC subjects Cd correlates negatively with the tangles but not significantly so (p>0.1).
