Background For patients w.th cardiovascular disease (CVD), co-existence of peripheral artery disease (PAD) predicts increased mortality, and such patients are also more likely to benefit from aggressive therapy. Surveillance of PAD is often neglected at health clinics. Our aim is to highlight the importance and ease of surveillance of PAD in patients w.th CVD. Objective To determine the prevalence of symptomatic and asymptomatic PAD in a Malaysian patient population w.th documented CVD. Methods and Results A total of 393 subjects w.th established CVD w.re recruited from three centres (85 w.men and 308 men), as part of a larger international (AGATHA) survey. PAD, determined by presence of claudicant symptoms on interview.and/or abnormal ankle-brachial index (ABI) score of less than 0.9, w.s present in 21.4% of patients-of w.om 64% w.re asymptomatic. Abnormal ABI is associated w.th higher systolic blood pressure and number of arterial beds affected. Conclusions Concomitant PAD is prevalent among CVD patients in Malaysia. ABI screening is simple and yields a high proportion of patients w.th extensive atherosclerosis w.o may require more aggressive atherosclerotic risk management.(j Geriatr Cardiol 2007;4:195-199.)

angiotensin II (ang II) is a critical component of the reninangiotensin system that contributes to hypertension. Although platelets in blood from hypertensive subjects have an abnormal biological profile, it is unclear if circulating ang II influences platelet aggregation or thrombus formation. One of the abnormalities presented to the platelets during hypertension is an elevated plasma concentration of serotonin (5-HT) caused by reduced 5-HT uptake secondary to loss of the 5-HT transporter (SERT) on the platelet plasma membrane. In the current study, w. evaluated in vivo platelet function after 7 days of subcutaneous ang II infusion to establish hypertension in mice and additionally assessed the biology of isolated platelets exposed to ang II in vitro. The administration of ang II elevated systolic blood pressure, but markers of platelet activation including P-selectin and PEjon/A staining w.re not changed. How.ver, the aggregation response to collagen w.s reduced in isolated platelets from ang II-infused mice, w.ich also show.d reduced 5-HT uptake by SERT. In vitro exposure of isolated platelets to ang II also resulted in a loss of surface SERT associated w.th a reduced aggregation response to collagen. These abnormalities w.re reversed by increasing concentra tions of the ang II receptor antagonist, valsartan. Interestingly, SERT KO mice failed to fully develop hypertension in response to ang II infusion and isolated platelets from these animals w.re insensitive to the anti-aggregatory influence of ang II. Thus, ang II blunts the aggregation responses of platelets and the mechanism underlying this action may involve a loss of SERT on the platelet plasma membrane. The latter event depletes intracellular 5-HT in platelets, an event that is associated w.th reduced aggregation. The w.despread use of antihypertensive drugs that target the renin-angiotensin system suggest the potential clinical utility of our findings and emphasize the importance of understanding the i

This study aimed to identify the influencing factors on choice of dialysis modality in patients aged 60 years or more and the barriers and/or facilitators in the decision-making process. A descriptive, cross-sectional study w.s conducted involving patients undergoing renal replacement therapy for at least three months. Of the 55 patients included, 35 (64%) w.re under medical care before starting dialysis. The majority of patients, 55% (30), reported being consulted regarding the type of dialysis they w.uld like. The most chosen therapy w.s hemodialysis w.th physician indication being the most influencing factor on the choice of dialysis modality. Visual and mobility problems w.re those principally reported by the elderly participants. This study suggests the need for greater pre-dialysis participation by the multidisciplinary team and emphasizes the importance of patient involvement in the decision-making process.

A pilot w.re draw.ng machine as w.ll as w.re end-pointing roller w.s developed. Using these machines, a w.re draw.ng test for four different coating materials and tw. different lubricants w.s performed as the reduction ratio increased from 10% to 30%. Materials used for a substrate in this study are plain carbon steel （AIS11045） and ultra low.carbon bainite steel. To compute the friction coefficient betw.en the coating layer of w.re and the surface of die lbr a specific lubricant, a series of finite element analyses w.re carried out. SEM observations w.re also conducted to investigate the surface defects of w.re deformed. Results show.that the behavior of draw.ng force varies w.th the lubricant-type at the initial stage of draw.ng. The pow.er-typed lubricant w.th a large particle causes the retardation of lull lubrication on the entire contact surface and the local delamination of coating layer on the w.re surface. As the flow.stress of a substrate increases, the delamination becomes severe.

The objectives of this study w.re to （1） determine the distribution and synthesis of pericellular matrix （PCM） molecules （collagen VI, collagen IV and laminin） in rat temporomandibular joint （TMj） and （2） investigate the effects of PCM molecules on chondrocytes against inflammation in osteoarthritis. Four zones （fibrous, proliferating, mature and hypertrophic） of condylar cartilage and three bands （anterior, intermediate and posterior） of disc w.re analysed by immunohistochemistry for the presence of PCM molecules in rat TMjs. Isolated chondrocytes w.re pre-treated w.th PCM molecules before being subjected to interleukin （IL）-II~ treatment to stimulate inflammation. The responses of the chondrocytes w.re analysed using gene expression, nitric oxide release and matrix metalloproteinase （MMP）-13 production measures. Histomorphometric analyses revealed that the highest areal deposition of collagen VI （67.4%）, collagen IV （45.7%） and laminin （52.4%） w.s in the proliferating zone of TMj condylar cartilage. No significant difference in the distribution of PCM molecules w.s noted among the three bands of the TMj disc. All three PCM molecules w.re expressed intracellularly by chondrocytes cultured in the monolayer. Among the PCM molecules, pre-treatment w.th collagen VI enhanced cellular proliferation, ameliorated IL-lp-induced MMP-3, MMP-9, MMP-13 and inducible nitric oxide synthase gene expression, and attenuated the dow.regulation of cartilage matrix genes, including collagen I, aggrecan and cartilage oligomeric matrix protein （COMP）. Concurrently, collagen VI pretreatment inhibited nitric oxide and MMP-13 production. Our study demonstrates for the first time the distribution and role of PCM molecules, particularly collagen VI, in the protection of chondrocytes against inflammation.

汉语与土耳其语定语类型比较与习得研究

定语是汉语学习中的一个重要的语法点。近年来,许多专家研究了汉语和韩语的定语,汉语和泰语的定语,汉语和越南语的定语,汉语和俄语的定语,汉语和英语的定语等,但是迄今为止,中国的学者鲜有对汉语和土耳其的定语进行深入系统的对比研究。随着中国“一带一路”的提出,中国和土耳其在经济、文化上的交往越来越密切,土耳其学生学汉语的热情也越来越高,到中国留学的土耳其学生也越来越多。但是由于土耳其语和汉语语言类型并不相同,土耳其语是黏着语,汉语是孤立语,土耳其语里面很少专门讲定语的,但是汉语的定语是汉语句法的一个很重要的句法成分,汉语的定语研究是汉语的语法的一个研究热点。土耳其学生在学习汉语的定语时候遇到很多困难,所以汉语和土耳其定语的比较研究非常有现实意义。本文在考察汉语与土耳其语定语基本类型基础上,运用结构主义语言学的方法进行对比分析,对土耳其语和汉语定语的结构类型及其特征进行比较分析研究。本文对下列内容进行对比分析:汉语定语的成分类型;土耳其语定语类型、土耳其语定语与汉语定语共同点与区别的对比分析。尽管土耳其语定语和汉语定语在句法、语义等方面存在不少差异,但是也有共性,比如两种语言的多项定语与中心语都遵循距离象似性原则,即越能说明中心沿所指的稳定而恒久的本质属性的词语充当定语,其位置越靠近中心语;反之,则离中心语越远。换言之,多项定语与中心语之间线性距离的远近反映了二者之间语义关系的远近。本文的最终目的就是希望把所研究的成果运用到对土耳其人学习汉语上,为中国老师教授土耳其学生提供一定借鉴,提高汉语教学的效果和质量。希望本文所得出的结论能够对土耳其学生学习汉语、教师教学和中土语言文化交流起到积极的促进作用。
