Relations of APOE promoter polymorphisms to LDL cholesterol and markers of subclinical atherosclerosis in young adults

The common apolipoprotein E (apoE) gene (APOE) epsilon2/epsilon3/epsilon4 polymorphism explains part of serum lipid variation, and polymorphisms in the APOE promoter region have been proposed to participate in the regulation of serum lipid levels within the most common APOE epsilon3/epsilon3 genotype group. We determined APOE -219G/T and +113G/C promoter genotypes and estimated APOE haplotypes in 525 participants of the Cardiovascular Risk in Young Finns Study. We studied the associations of the APOE promoter polymorphisms and their haplotypes with cross-sectional and longitudinal serum lipid and apolipoprotein concentrations as well as with flow-mediated dilatation (FMD), carotid artery compliance (CAC), and intima-media thickness (IMT) within the APOE epsilon3/epsilon3 carriers. We found no significant association between the APOE promoter genotypes and serum lipids [low density lipoprotein-cholesterol (LDL-C), HDL-C, and triglycerides], apolipoproteins (apoA-I and apoB), or brachial artery FMD, CAC, or carotid IMT in either men or women. In longitudinal analyses in males, the carriers of heterozygous genotypes (-219G/T or +113G/C) and, furthermore, carriers of the -219T/+113C/epsilon3 haplotype had significantly higher LDL-C and total cholesterol concentrations throughout the 21 year follow-up period compared with homozygous G allele carriers or noncarriers of the -219T/+113C/epsilon3 haplotype. Such associations were not found in females. In summary, the APOE promoter polymorphisms -219G/T and +113G/C as well as their haplotype are associated with longitudinal changes in LDL-C and total cholesterol concentrations in young Finnish males but do not seem to be major determinants for FMD, CAC, or carotid IMT in males or females.     

比较两种测量方法获得的血压波动对老年颈动脉斑块的影响

目的:比较两种不同血压波动测定方法测定的血压波动与颈动脉斑块发生的关系。方法:以1456名患有动脉硬化老年男性患者为研究对象,监测患者24 h动态血压,根据有无颈动脉斑块将入选患者分为2组:颈动脉斑块组(n=1012)和无颈动脉斑块组(n=444),分别采用经典的标准差方法(SD法)和个体血压波动测定方法(个体法)分别测定每位患者的血压波动,回顾性分析这两种方法测定的血压波动与颈动脉斑块形成的关联性。结果:SD法测定颈动脉斑块组24 h收缩期血压波动(SBPV)、白天SBPV、夜间SBPV以及24 h舒张期血压波动(DBPV)水平均明显高于无颈动脉斑块组(P0.05);而白天和夜间DBPV差异无统计学意义。个体法测定颈动脉斑块组24 h SBPV、白天SBPV、24 h DBPV以及白天DBPV水平较无颈动脉斑块组均明显升高(P0.05);夜间SBPV和夜间DBPV差异无统计学意义(P0.05)。比较颈动脉斑块组SBPV值出现次数,SD法测定SBPV最多的是10-15 mmHg(n=541),其次是大于15 mmHg(n=399);个体法测定颈动脉斑块组SBPV值出现次数最多的是0-8 mmHg(n=490),其次是8-10 mmHg(n=350)。结论:在老年男性动脉硬化相关疾病患者中,血压波动与颈动脉斑块的形成有着密切的关系,两种方法均可测定血压波动,但以个体血压波动测定方法更加敏感。     

The zinc finger homeodomain-2 gene of Drosophila controls Notch targets and regulates apoptosis in the tarsal segments

The development of the Drosophila leg is a good model to study processes of pattern formation, cell death and segmentation. Such processes require the coordinate activity of different genes and signaling pathways that progressively subdivide the leg territory into smaller domains. One of the main pathways needed for leg development is the Notch pathway, required for determining the proximo-distal axis of the leg and for the formation of the joints that separate different leg segments. The mechanisms required to coordinate such events are largely unknown. We describe here that the zinc finger homeodomain-2 (zfh-2) gene is highly expressed in cells that will form the leg joints and needed to establish a correct size and pattern in the distal leg. There is an early requirement of zfh-2 to establish the correct proximo-distal axis, but zfh-2 is also needed at late third instar to form the joint between the fourth and fifth tarsal segments. The expression of zfh-2 requires Notch activity but zfh-2 is necessary, in turn, to activate Notch targets such as Enhancer of split and big brain. zfh-2 is controlled by the Drosophila activator protein 2 gene and regulates the late expression of tarsal-less. In the absence of zfh-2 many cells ectopically express the pro-apoptotic gene head involution defective, activate caspase-3 and are positive for acridine orange, indicating they undergo apoptosis. Our results demonstrate the key role of zfh-2 in the control of cell death and Notch signaling during leg development.

Computer aided diagnosis of Coronary Artery Disease,Myocardial Infarction and carotid atherosclerosis using ultrasound images: A review

The diagnosis of Coronary Artery Disease (CAD), Myocardial Infarction (MI) and carotid atherosclerosis is of paramount importance, as these cardiovascular diseases may cause medical complications and large number of death. Ultrasound (US) is a widely used imaging modality, as it captures moving images and image features correlate well with results obtained from other imaging methods. Furthermore, US does not use ionizing radiation and it is economical when compared to other imaging modalities. However, reading US images takes time and the relationship between image and tissue composition is complex. Therefore, the diagnostic accuracy depends on both time taken to read the images and experience of the screening practitioner. Computer support tools can reduce the inter-operator variability with lower subject specific expertise, when appropriate processing methods are used. In the current review, we analysed automatic detection methods for the diagnosis of CAD, MI and carotid atherosclerosis based on thoracic and Intravascular Ultrasound (IVUS). We found that IVUS is more often used than thoracic US for CAD. But for MI and carotid atherosclerosis IVUS is still in the experimental stage. Furthermore, thoracic US is more often used than IVUS for computer aided diagnosis systems.     

脑梗死患者血浆纤维蛋白原水平与颈动脉粥样硬化的关系

目的：探讨脑梗死患者血浆纤维蛋白原（Human Fibrinogen,Fro）水平的改变与颈动脉粥样硬化（CAS）的关系。方法：选取2009年5月-2012年6月入住解放军八一医院神经内科脑梗死患者508例。采用彩色多普勒超声检测脑梗死患者颈内动脉颅外段（／ntemalcarotidartery,ICA）、总动脉（common carotid artery,CCA）、颈总动脉分叉处内一中膜厚度（Intima—medial Thickness,IMT）。评定标准：颈动脉IMT〉0．9toni或（和）颈动脉斑决定义为CAS。24h内将患者空腹静脉血送检,记录测定后的生化指标及№水平,记录吸烟史、糖尿痛、高血压病等病史,采用Logistic回归分析测定的相关危险因素对颈动脉粥样硬化的作用强度。结果：按FIB水平分组（FIB≤3g／L组、FIB〉3g／L组）,Logistic回归分析显示FIB〉3g／L组的危险度为2．04,年龄、FIB水平、高血压病史及吸烟史对CAS有影响,差异有统计学意义（P〈0．05）,其中FIB与CAS的相关性最强。结论：FIB水平与脑梗死患者CAS的发展密切相关,其作用可能强于其他的传统危险因素。
