journal of Geriatric Cardiology 2005年第2期2卷 123-128页

The aging of the population and improvements in outcomes after cardiovascular surgery have resulted in a worldwide growing demand of complex surgical intervention for elderly patients. We briefly review the up-to-date english-language literature with particular focus on cardiovascular surgery in elderly patients. With earlier referral, careful preoperative evaluation, strategic planning, and the continuing efforts in optimizing surgical techniques, operative mortality and morbidity following primary or reoperative coronary artery bypass grafting and valvular interventions are expected to fall in this high-risk patient subset. Importantly, accumulating evidence indicates that elderly patients may benefit from improved functional status and quality of life after cardiovascular surgical therapy(j Geriatr Cardiol 2005,2(2): 123-128).

马方综合征(Marfan syndrome,MFS)是一种由原纤维蛋白-1(fibrillin-1,FBN-1)突变引起的全身性遗传性疾病,FBN-1基因突变与MFS相关表型的联系相关,目前已报道的MFS常见的眼部表现包括角膜扁平、长眼轴、晶状体异位以及视网膜病变等异常,这些眼部异常将对MFS患者的视力产生影响,如角膜异常可影响角膜高阶像差的异常,可能导致近视或散光等屈光状态异常,从而影响视觉质量,损害视力清晰度。此外,MFS的眼底血管病变,也可能导致MFS患者的视力丧失,研究发现,MFS视网膜血管及脉络膜血管的密度较正常人减少,并与最佳矫正视力相关,由于光感受器的代谢与营养供应与视网膜及脉络膜血管息息相关,血管异常可能与视力损失相关。由于MFS患者存在视力损害的风险,其早期诊断和治疗尤为重要,因此,了解MFS眼部病变的特点及其对视力的影响,对制定针对MFS眼病的治疗方案具有重要的意义。另外,由于MFS眼部异常与FBN1基因突变相关,其基因突变类型多样,致病机制复杂,总结MFS眼部特点对其发病机制的继续探索有一定的指导作用,因此,文章拟就MFS患者眼部生物学参数特点及其对视力的影响这一领域国内外的相关研究进展进行综述。

In recent years,the ternary system BaO-ZnO- TiO is of great interest in the production of microwave dielectric *** addition of ZnO to the barium polytitanates has been found to improve their dielectric property. Knowledge of crystallography of phases in the Ba-Zn-Ti-0 system is important to understand the physical properties of these materials.

The Aging Tsunami as it is often quoted to describe the worrying situations of rapidly aging in China has not met with detail planning in facilities upgrade and careful consideration in service models. Broad brushed central policies categorizes services into home care, community care and institutional care and set policy goals at 90-6-4, representing the percentage of older people in receiving respective care. This leaves local officials helpless on how these ideals can be actualized. Some cities have inclined to build huge older people homes and pour resources into institutional care, forgetting the need for older people to be connected with the society. This paper reviews the historical developments of older people services in Hong Kong and recommends an integrative model of social work services connecting institutional, community and home care into a seamless network. The city of Zhuhai will be presented as a perfect experimental city on how its existing facilities can be converted and developed according to the model. Survey on the situations of the 16 public older people homes will be used to illustrate the potentials of an integrative model.
