PURPOSE: This study has a purpose to suggest research and intervention directions for health promoting behaviors (HPB) of the Korean middle-aged in the future. METHODS: Forty four articles on HPB of the Korean middle-aged were reviewed and analyzed. The articles analyzed are theses written for a doctoral or master's degree and published between 1995 and 2007. RESULTS: 1. As for the major characteristics of the subject groups, most of them were between 40 and 60 years old (61.4%), were females (79.5%), and resided in cities (84.1%). 2. The dependent variables adopted were physiological, psychological and cognitive factors (self-efficacy, knowledge of health management, etc.), HPB and factors related to Health Promoting Lifestyle Profile (HPLP). 3. The average scores of HPLP were 1.57~3.08 on a 4-point scale. The highest score was observed in self-actualization, and the lowest score in exercise. 4. Self-efficacy, perceived health status and income had significant correlations with HPB. 5. In regression analysis, self-efficacy, self-esteem and perceived health status were the most powerful predictors. CONCLUSION: It is necessary to develop intervention tools for more diverse HPB of the Korean middle-aged. The interventions are recommended to focus on increasing exercise and to use strategies for improving self-efficacy and self-esteem.

High-dose steroid therapy is known as effective adjuvant therapy for refractory bone pain due to metastasis of solid cancer. However, the standard dose and duration have not been established to date. Long term maintenance with steroid therapy is not encouraged due to its potential adverse effects. Here, we report a case of a terminal cancer patient who maintained high dose steroid therapy to alleviate refractory bone pain with complication of systemic fungal infection.

We have previously shown that the inhibition of fibroblast growth factor (FGF) signaling induced endodermal gene expression in the animal cap and caused the expansion of the endodermal mass in Xenopus embryos. However, we still do not know whether or not the alteration of FGF signaling controls embryonic cell fate, or when FGF signal blocking is required for endoderm formation in Xenopus. Here, we show that FGF signal blocking in embryonic cells causes their descendants to move into the endodermal region and to express endodermal genes. It is also interesting that blocking FGF signaling between fertilization and embryonic stage 10.5 promotes endoderm formation, but persistent FGF signaling blocking after stage 10.5 restricts endoderm formation and differentiation.

BMP-4 signaling is mediated through Smad proteins which may translocate to the nucleus to activate transcription. Little is known about how BMP-4 signaling regulates the transcription of its target genes, e.g., Xvent genes. Therefore, we isolated the genomic clone of a BMP-4 responsive homeobox gene, Xbr-1a/Xvent-2. This clone contains a promoter and three exons for the entire coding region. Using the primer extension, we identified the transcription initiation site corresponding to position -64 bp upstream to the ATG codon of the Xvent-2 gene. The promoter was linked to the luciferase reporter gene, and promoter activity determined by luciferase assay. The temporal promoter activity peaked between embryonic stages 13~17, in agreement with its temporal mRNA expression in the whole embryo. Through the serial deletion mutation, the upstream -235 bp of the promoter retains the full transcriptional activity, and is regulated by BMP-4 signaling. The present results suggest that the BMP-4 responsive element is located on the upstream 235 bp of the promoter.

BACKGROUND: Usual interstitial pneumonia (UIP) is a progressive disorder characterized by a poor response to conventional immunosuppressive agents and significant mortality. The histologic hallmark of UIP is patchy subpleural fibrosis with interposed fibroblastic foci(FBF) and relatively normal appearing lung. FBF is a collection of actively proliferating myofibroblasts, which may represent the activity of IPF. However, there were contradictory reports about the correlation between the degree of FBF and survival. The objective of this study was to investigate the roles of FBF as prognostic marker of UIP. METHOD: This was a retrospective study on the 46 patients(M:F=33:13, mean age:59+/-12 years) who had the surgical lung biopsy done at the Asan Medical Center, Seoul, Korea between 1990 and 2000 and had follow-up of more than a year. All the biopsy specimens were reevaluated and diagnosed as UIP according to the new classification. Semiquantitative grading of FBF(absent, 0; mild 1; moderate 2; marked 3) was performed by the experienced pathologists and compared to the clinical data and the follow up course. RESULTS: Thirteen patients(28.2%) died of UIP progression during the study period. The median survival time of all the subjects was 26 months after the biopsy. The FVC, DLco, smoking history and the grade of FBF were significantly related to the risk of death. The survival was longer in subjects with lesser degrees of FBF, higher DLco, higher FVC and history of smoking .The multivariate analysis with Cox regression test showed the extent of FBF was the only independent prognostic marker of UIP. CONCLUSION: These data suggested that the extent of FBF on the surgical lung biopsy can be used as a prognostic marker of UIP.
