目的 :探讨三维超声心动图评价左心耳功能的价值。方法 :采用三维超声心动图对 5 2例正常人及二尖瓣病变伴或不伴心房纤颤患者测定左心耳容量及其收缩功能 ,并与二维超声心动图和多普勒超声心动图比较。结果 :根据左心耳容量测定计算出的左心耳射血分数 (EFv)与左心耳峰值血流排空速度 (Pev)相关良好 (r=0 .818,P0 .0 5 ) ,但在重复性检验中 EFa的范围和两测量数值之差的均数加减标准差都大于 EFv的相应数值 ,左心耳容量在正常人明显小于有二尖瓣病变的患者 ,而收缩功能则前者明显高于后者 (P值均 <0 .0 1) .在相同二尖瓣病变患者之间进行比较 ,合并房颤者左心耳容量大于窦性心率者 ,而左心耳收缩功能则前者低于后者 (P值均 <0 .0 5 )。另外 ,二尖瓣病变合并房颤者的左心耳自发性“超声造影”发生率高于窦性心率者。结论 :用三维超声心动图测量左心耳容量和评价其收缩功能是可行的 ,评价左心耳功能时较二维超声心动图更准确 ,二尖瓣病变患者的左心耳容量增加 ,收缩功能减低 ,常伴左心耳自发性“超声造影”,上述改变在合并房颤者更

Efficiently querying Description Logic (DL) ontologies is becoming a vital task in various data-intensive DL applications. Considered as a basic service for answering object queries over DL ontologies, instance checking can be realized by using the most specific concept (MSC) method, which converts instance checking into subsumption problems. This method, however, loses its simplicity and efficiency when applied to large and complex ontologies, as it tends to generate very large MSCs that could lead to intractable reasoning. In this paper, we propose a revision to this MSC method for DL SHI , allowing it to generate much simpler and smaller concepts that are specific enough to answer a given query. With independence between computed MSCs, scalability for query answering can also be achieved by distributing and parallelizing the computations. An empirical evaluation shows the efficacy of our revised MSC method and the significant efficiency achieved when using it for answering object queries.

Advances in Alzheimer's Disease 2023年第3期12卷 38-54页

During the prodromal stage of Alzheimer’s disease (AD), neurodegenerative changes can be identified by measuring volumetric loss in AD-prone brain regions on MRI. Cognitive assessments that are sensitive enough to measure the early brain-behavior manifestations of AD and that correlate with biomarkers of neurodegeneration are needed to identify and monitor individuals at risk for dementia. Weak sensitivity to early cognitive change has been a major limitation of traditional cognitive assessments. In this study, we focused on expanding our previous work by determining whether a digitized cognitive stress test, the Loewenstein-Acevedo Scales for Semantic Interference and Learning, Brief Computerized Version (LASSI-BC) could differentiate between Cognitively Unimpaired (CU) and amnestic Mild Cognitive Impairment (aMCI) groups. A second focus was to correlate LASSI-BC performance to volumetric reductions in AD-prone brain regions. Data was gathered from 111 older adults who were comprehensively evaluated and administered the LASSI-BC. Eighty-seven of these participants (51 CU;36 aMCI) underwent MR imaging. The volumes of 12 AD-prone brain regions were related to LASSI-BC and other memory tests correcting for False Discovery Rate (FDR). Results indicated that, even after adjusting for initial learning ability, the failure to recover from proactive semantic interference (frPSI) on the LASSI-BC differentiated between CU and aMCI groups. An optimal combination of frPSI and initial learning strength on the LASSI-BC yielded an area under the ROC curve of 0.876 (76.1% sensitivity, 82.7% specificity). Further, frPSI on the LASSI-BC was associated with volumetric reductions in the hippocampus, amygdala, inferior temporal lobes, precuneus, and posterior cingulate.

AIM: To analyze,retrospectively in a population-based study,the management and survival of patients with recurrent rectal cancer initially treated with a macroscopically radical resection obtained with total mesorectal excision (TME). METHODS: All rectal carcinomas diagnosed during 1998 to 2000 and initially treated with a macroscopically radical resection (632 patients) were selected from the Amsterdam Cancer Registry. For patients with recurrent disease,information on treatment of the recurrence was collected from the medical records. RESULTS: Local recurrence with or without clinically apparent distant dissemination occurred in 62 patients (10%). Thirty-two patients had an isolated local recurrence. Ten of these 32 patients (31%) underwent radical re-resection and experienced the highest survival (three quarters survived for at least 3 years). Eight patients (25%) underwent non-radical surgery (median survival 24 mo),seven patients (22%) were treated with radio-and/or chemotherapy without surgery (median survival 15 mo) and seven patients (22%) only received best supportive care (median survival 5 mo). Distant dissemination occurred in 124 patients (20%) of whom 30 patients also had a local recurrence. The majority (54%) of these patients were treated with radio-and/or chemotherapy without surgery (median survival 15 mo). Twenty-seven percent of these patients only received best supportive care (median survival 6 mo),while 16% underwent surgery for their recurrence. Survival was best in the latter group (median survival 32 mo). CONCLUSION: Although treatment options and survival are limited in case of recurrent rectal cancer after radical local resection obtained with TME,patients can benefit from additional treatment,especially if a radical resection is feasible.
