We present a dynamic description logic for representation and reasoning about actions, with an approach that embrace actions into the description logic ALCO@. With this logic, description logic concepts can be used for describing the state of the world, and the preconditions and effects of atomic actions; Complex actions can be modeled with the help of(More)
BACKGROUND Pachydermodactyly is an infrequently reported disease characterized clinically by painless swelling of the soft tissues at interphalangeal joints. Histopathologic features include increased dermal accumulation of collagen fibers. Young males are predominantly affected. There are only approximately 50 cumulative cases reported worldwide. (More)
Many physicians express a relatively nihilistic approach to the treatment of hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). Consensus among surgeons regarding the indications for an aggressive approach has not been reached. Current study was aimed to determine whether an aggressive approach, with an extended resection with(More)
A fast-track clinical pathway is designed to streamline patient care delivery and maximize cost effectiveness. It has decreased postoperative length of stay (LOS) and hospital charges for many surgical procedures. However, data on clinical pathways after liver surgery are sparse. This study examined whether use of a fast-track clinical pathway for patients(More)
We present a dynamic description logic D-ALCO@ for representing knowledge about dynamic application domains. D-ALCO@ is a combination of a typical action theory and the description logic ALCO@, in such a way that actions are treated as citizens of the logic. Actions of D-ALCO@ are explicitly specified with the help of formulas, and are then used in the(More)
β-thalassemia is a common inherited disorder worldwide including southern China, and at least 45 distinct β-thalassemia mutations have been identified in China. High-resolution melting (HRM) assay was recently introduced as a rapid, inexpensive and effective method for genotyping. However, there was no systemic study on the diagnostic capability of HRM to(More)
The relation between lead (Pb) and iron (Fe) becomes increasingly concerned because they are both divalent metals that are absorbed by the same intestinal mechanism, and Pb exposure and Fe deficiency in the developmental brain, as well as Fe overload in the aged brain, can cause cognitive deficits. However, the interaction between Pb exposure and Fe status(More)
The principal effects of Pb(2+) exposure in children are attention, memory and learning deficits that persist into adulthood. The application of the conventional chelators in children is somewhat prohibited by adverse health effects and is not effective in reversing learning deficits once they have occurred. In this study, we applied the nutrients,(More)
The potential for genetic variation to modulate neonatal hyperbilirubinemia risk is increasingly being recognized. A case-control study was designed to assess comprehensive contributions of the multiple genetic modifiers of bilirubin metabolism on significant neonatal hyperbilirubinemia in Chinese descendents. Eleven common mutations and polymorphisms(More)
