AIM To investigate the prevalence of advanced polyps in asymptomatic Chinese and to determine the risk of proximal advanced colonic polyps in subjects with and without polyps in the distal colon. METHODS Data were collected prospectively during colonoscopic examinations performed in 5 973 subjects as part of health evaluation at our unit from December(More)
BACKGROUND Although eradication of Helicobacter pylori infection can decrease the risk of gastric cancer, the optimal regimen for treating the general population remains unclear. We report the eradication rate (intention-to-treat and per protocol) of a community-based H. pylori therapy using the strategy of test, treat, retest, and re-treat initial(More)
To facilitate sequential data transfer (e.g., bus or pipeline signals) and reduce bounded net delay (as well as total wirelength), it is desired to align circuit blocks one by one and constrain the blocks within a certain bounding box. In this paper, we handle the placement with alignment and performance (delay) constraints using the B*-tree representation.(More)
— Using voltage island methodology to reduce power consumption for System-on-a-Chip (SoC) designs has become more and more popular recently. Currently this approach has been considered either in system-level architecture or post-placement stage. Since hierarchical design and reusable intellectual property (IP) are widely used, it is necessary to optimize(More)

BACKGROUND Large anterior choroidal artery (AChA) infarcts are frequently associated with stroke evolution. This study aimed to investigate the major determinants for stroke evolution in patients with large AChA infarcts. METHODS We studied 118 consecutive adult patients with acute large AChA infarcts. The diagnosis was confirmed as abnormal(More)
A 60-year-old man with a history of atrial fibrillation had an acute onset of ballistic movements of the left limbs with sensory extinction (video on the Neurology® Web site at www.neurology.org). The patient was treated with risperidone and anticoagulant; symptoms subsided 3 days later. Brain MRI showed acute infarction of the right posterior parietal lobe(More)
