We have developed a rule-based system, which is called Chinese question answering system for reading comprehension (Cqarc). This paper systematically introduces and discusses key techniques in the Cqarc, describes the processing mechanism of the Cqarc, presents processing strategies and methods in the Cqarc. Cqarc uses heuristic rules to look for lexical(More)
The aims of this study were to observe the effects of thalidomide on a rat model of pulmonary fibrosis, to determine the protein expression levels of phosphorylated c-Jun N-terminal kinase (p-JNK) and α-smooth muscle actin (α-SMA) and to explore the mechanism underlying the preventive effect of thalidomide on pulmonary fibrosis. Ninety healthy male Wistar(More)
ETHNOPHARMACOLOGICAL RELEVANCE The herb of Chelidonium majus Linn is known to possess a variety of biological activities and applied in the therapy of various infectious diseases. AIM OF THE STUDY To evaluate the in vitro antifungal activity of the active components from Chelidonium majus against clinical drug-resistant yeast isolates. MATERIALS AND(More)
OBJECTIVE To explore the potential applications of a chamber for in vivo tissue engineering, and to establish a novel model for in vivo tissue-engineered cartilage. METHODS Four experimental groups were included in this study: (A) chambers + chondrocytes/collagen gel; (B) chambers + chondrocytes/PLGA gel; (C) chondrocytes/collagen gel alone; and (D)(More)
Vascular invasion and admixture of the nude mouse cells with seeded cells make it difficult to reapply the regenerated tissues to the restoration of host tissue defects. Therefore, a device that is capable of allowing for autologous or allogenic tissue growth while preventing host tissue invasion will be a valuable tool for in vivo tissue engineering. We(More)
The formation of Sematic Web Services (SWS) makes it possible to discover, implement and compose Web service automatically. OWL-S, the description language of Sematic Web Service, increases flexibility of Web service description, enriches expressiveness of it and provides a capability-based mechanism of Web service discovery. We introduce a automatic(More)
To study the expression of human intestinal trefoil factor (hITF) mRNA in Crohn’s disease and to screen the cellular proteins that can interact with the hITF protein by a yeast two-hybrid system in order to explore the mechanism of hITF in protecting intestinal mucosa from injury. Seventy-eight patients underwent double-balloon enteroscopy (DBE). Expression(More)
BACKGROUND Fat tissue graft has been commonly used for soft tissue augmentation. However, the mechanisms underlying the maintenance of graft volume and weight are still unclear. As morphological features provide direct evidences for cell death and survival, we aimed to investigate the fate of grafted adipocytes and the dynamic changes in the remodeling of(More)
BACKGROUND Propofol (2,6-diisopropylphenol) is one of the most frequently used anesthetic agents. One of the main side effects of propofol is to reduce blood pressure, which is thought to occur by inhibiting the release of catecholamines from sympathetic neurons. Here, the authors hypothesized that propofol-induced hypotension is not simply the result of(More)
Recent years have seen a revived interest in semantic parsing by applying statistical and machine learning methods to semantically annotate corpora such as the FrameNet and the Proposition Bank So far much of the research has been focused on English due to the lack of semantically annotated resources in other languages. This paper reports first results on(More)
