舒张性心力衰竭患者基础疾病特点分析

目的：探讨舒张性心力衰竭与原发性高血压病、糖尿病、冠心病的相关性.方法：通过填写心力衰竭调查表、体格检查、生化检查、超声心动图检查,并结合其他检查结果,将参加实验人群分为：舒张性心力衰竭（DHF）组、收缩性心力衰竭（SHF）组,心功能正常（NL）组.进行基础疾病（原发性高血压病、糖尿病、冠心病）相关分析.结果：DHF组（239例）的高血压病、冠心病、糖尿病分别占55.8%,37.7%,16.3%;SHF组（81例）分别占71.6%,61.7%,18.5%;NL组（250例）分别占45.2%,21.2%,10.4%.SHF组、DHF组与NL组比较,原发性高血压、冠心病发病率明显升高,有统计学意义（P〈0.05）;DHF组与SHF组相比较,只有冠心病的发病率有统计学意义（P〈0.05）.结论：原发性高血压是产生DHF的主要病因,其次为冠心病、糖尿病为可能原因.     

Is retaining the youthful functional anatomy underlying speed of information processing a signature of successful cognitive ageing? An event-related fMRI study of inspection time performance

It has been hypothesized that individual differences in cognitive ageing might in part be based on the relative preservation of speed of information processing. However, the biological foundations of processing speed are not understood. Here we compared two groups of non-demented older people who had relatively similar IQs at age 11 but differed markedly in non-verbal reasoning ability at age 70: 'cognitive sustainers' (n=25), and 'cognitive decliners' (n=15). Using an event-related fMRI design, we studied the BOLD response while they performed an inspection time task. Inspection time is a two-alternative forced choice, backward masking test of the speed of the early stages of visual information processing. Inspection time has a well-established, significant association with higher cognitive abilities. The group of cognitive sustainers showed a pattern of BOLD activation-deactivation in response to inspection time stimulus duration differences that was similar to a healthy young sample [Deary, I.J., Simonotto, E., Meyer, M., Marshall, A., Marshall, I., Goddard, N., Watdlaw, J.M., 2004a. The functional anatomy of inspection time: an event-related fMRI study. NeuroImage 22, 1466-1479]. The group of cognitive decliners lacked these clear neural networks. The relative preservation of complex reasoning skills in old age may be associated with the preservation of the neural networks that underpin fundamental information processing in youth.
