  The clinical utility of the Hopkins Verbal Learning Test as a screening test for mild dementia

  摘要：

  Objective: The purpose of this study was to determine whether the Hopkins Verbal Learning Test (HVLT) could be used as a valid and reliable screening test for mild dementia in older people, and to compare its performance to that of the Mini-Mental State Examination (MMSE). Method: Using a cross-sectional design, we studied three groups of older subjects recruited from a district geriatric psychiatry service: (1) 26 patients with DSM-IV dementia and MMSE scores of 18 or better; (2) 15 patients with psychiatric diagnoses other than dementia; and (3) 15 normal controls. The relationship of each potential cutting point on the HVLT and the MMSE was examined against the independently ascertained DSM-IV diagnoses of dementia using a Receiver Operating Characteristic (ROC) analysis. Results: The subjects consisted of 21 (37.5%) males and 35 (62.5%) females with a mean age of 74.7 (SD 6.1) years and a mean of 8.5 (SD 1.8) years of formal education. ROC analysis indicated that the optimal cutting point for detecting mild dementia in this group of subjects using the HVLT was 18/19 (sensitivity=0.96, specificity=0.80) and using the MMSE was 25/26 (sensitivity=0.88, specificity=0.93). Conclusions: The HVLT can be recommended as a valid and reliable screening test for mild dementia and as an adjunct in the clinical assessment of older people. The HVLT had better sensitivity than the MMSE in detecting patients with mild dementia, whereas the MMSE had better specificity.

  末端乙炔和丙烯醛的钯催化原子经济合成共轭二烯

  摘要：

  共轭（E，E）二烯化合物由于其三官能，亲电性质以及（E，E）-二烯在各种功能分子中的普遍性而成为通用的合成中间体。本文表明，（E，E）二烯醛可以容易地在两个钯催化的步骤中由简单的，未活化的起始原料制备。末端乙炔和丙烯醛可通过共轭加成偶联，然后进行炔烃异构化。该程序提供了一种高度原子经济，氧化还原中性且实用的方法，可以以良好的收率和非对映选择性制备一系列共轭（E，E）二烯。
