OBJECTIVES: A healthcare decision-making support model and rule management system is proposed based on a personalized rule-based intelligent concept, to effectively manage chronic diseases. METHODS: A Web service was built using a standard message transfer protocol for interoperability of personal health records among healthcare institutions. An intelligent decision service is provided that analyzes data using a service-oriented healthcare rule inference function and machine-learning platform; the rules are extensively compiled by physicians through a developmental user interface that enables knowledge base construction, modification, and integration. Further, screening results are visualized for the self-intuitive understanding of personal health status by patients. RESULTS: A recommendation message is output through the Web service by receiving patient information from the hospital information recording system and object attribute values as input factors. The proposed system can verify patient behavior by acting as an intellectualized backbone of chronic diseases management; further, it supports self-management and scheduling of screening. CONCLUSIONS: Chronic patients can continuously receive active recommendations related to their healthcare through the rule management system, and they can model the system by acting as decision makers in diseases management; secondary diseases can be prevented and health management can be performed by reference to patient-specific lifestyle guidelines.

The study of antiviral pathways to reveal methods for the effective response and clearance of virus is closely related to understanding interferon (IFN) signaling and its downstream target genes, IFN-stimulated genes. One of the key antiviral factors induced by IFNs, 2'-5' oligoadenylate synthase (OAS), is a well-known molecule that regulates the early phase of viral infection by degrading viral RNA in combination with RNase L, resulting in the inhibition of viral replication. In this review, we describe OAS family proteins from a different point of view from that of previous reviews. We discuss not only RNase L-dependent (canonical) and -independent (noncanonical) pathways but also the possibility of the OAS family members as biomarkers for various diseases and clues to non-immunological functions based on recent studies. In particular, we focus on OASL, a member of the OAS family that is relatively less well understood than the other members. We will explain its anti- and pro-viral dual roles as well as the diseases related to single-nucleotide polymorphisms in the corresponding gene.

OBJECTIVE: Endometriosis is a very common gynecological condition in which tissue similar to endometrium proliferates at sites outside the uterine cavity. Although it generally remain a benign condition, malignant transformation has been documented, and it is commonly found in association with endometrioid subtype ovarian carcinoma. In order to identify the genomic change in those areas possibly involved in the pathogenesis of endometriosis, we performed LOH analysis. METHODS: Twenty seven cases of endometriosis were analyzed for the detection of LOH using 5 microsatellite markers. LOH analysis was performed by PCR, capillary electrophoresis and gene scan analysis using DNA from sections of tumor and normal tissue pairs. RESULTS: Twenty two of 27 (81.5%) cases demonstrated LOH at one or more loci. The frequency of LOH was 37.0% (D18S69), 25.9% (D22S274), 14.8% (D22S283), 7.4% (D6S286), 7.4% (D13S160). CONCLUSION: The frequencies of LOH was increased in higher stage of endometriosis. Most notable findings were found at chromosome 18 and 22 loci (D18S69, D22S274). These region might involve the some candidate genes closely related with the pathogenesis of endometriosis.

Genetic alterations have been recognized as an important event in the carcinogenesis of gastric cancer (GC). We conducted high resolution bacterial artificial chromosome array-comparative genomic hybridization, to elucidate in more detail the genomic alterations, and to establish a pattern of DNA copy number changes with distinct clinical variables in GC. Our results showed some correlations between novel amplified or deleted regions and clinical status. Copy-number gains were frequently detected at 1p, 5p, 7q, 8q, 11p, 16p, 20p and 20q, and losses at 1p, 2q, 4q, 5q, 7q, 9p, 14q, and 18q. Losses at 4q23, 9p23, 14q31.1, or 18q21.1 as well as a gain at 20q12 were correlated with tumor-node-metastasis tumor stage. Losses at 9p23 or 14q31.1 were associated with lymph node status. Metastasis was determined to be related to losses at 4q23 or 4q28.2, as well as losses at 4q15.2, 4q21.21, 4q 28.2, or 14q31.1, with differentiation. One of the notable aspects of this study was that the losses at 4q or 14q could be employed in the evaluation of the metastatic status of GC. Our results should provide a potential resource for the molecular cytogenetic events in GC, and should also provide clues in the hunt for genes associated with GC.

BACKGROUND: Xanthium stramarium (XAS) and Psoralea corylifolia (PSC), phototoxic oriental medicinal plants, has been used in traditional medicines in Asian countries. OBJECTIVE: The effects of highly purified XAS or PSC extract combined with ultraviolet A1 (UVA1) irradiation on cell proliferation and transforming growth factor-beta1 (TGF-beta1) expression of the keloid fibroblast were being investigated to define potential therapeutic uses for keloid treatments. METHODS: The keloid fibroblasts were treated with XAS or PSC alone or in the combination with UVA1 irradiation. The cell viability, apoptosis, and expression of TGF-beta1 and collagen I were investigated. RESULTS: XAS and PSC in combination with UVA1 irradiation suppressed cell proliferation and induced apoptosis of keloid fibroblasts. Furthermore, the XAS and PSC in combination with UVA1 irradiation inhibited TGF-beta1 expression and collagen synthesis in keloid fibroblasts. CONCLUSION: These findings may open up the possibility of clinically used XAS or PSC in combination with UVA1 irradiation for keloid treatments.

We report a case of Serratia marcescens peritonitis in a 45-year-old man with insulin-dependent diabetes mellitus undergoing continuous ambulatory peritoneal dialysis (CAPD). The patient presented with abdominal pain and cloudy dialysate. Empiric antibiotic therapy was initiated intraperitoneally with cefazolin and ceftazidime for 5 days. Cultures of the dialysate revealed S. marcescens, and the treatment was subsequently changed to gentamicin and ceftazidime. Oral ciprofloxacin was also added. The patient's abdominal pain and the dialysate white blood cell (WBC) count, however, did not improve. The indwelling CAPD catheter was therefore removed. This is an unusual case report in the Korean literature of S. marcescens peritonitis in a patient receiving CAPD.
