  • Cancer, a serious public health problem in worldwide, results from an excessive and uncontrolled proliferation of the body cells without obvious physiological demands of organs. The gastrointestinal tract, including the esophagus, stomach and intestine, is a unique organ system. It has the highest cancer incidence and cancer-related mortality in the body and is influenceed by both genetic and environmental factors. Among the various chemical elements recognized in the nature, some of them including zinc, iron, cobalt, and copper have essential roles in the various biochemical and physiological processes, but only at low levels and others such as cadmium, lead, mercury, arsenic, and nickel are considered as threats for human health especially with chronic exposure at high levels. Cadmium, an environment contaminant, cannot be destroyed in nature. Through impairment of vitamin D metabolism in the kidney it causes nephrotoxicity and subsequently bone metabolism impairment and fragility. The major mechanisms involved in cadmium carcinogenesis could be related to the suppression of gene expression, inhibition of DNA damage repair, inhibition of apoptosis, and induction of oxidative stress. In addition, cadmium may act through aberrant DNA methylation. Cadmium affects multiple cellular processes, including signal transduction pathways, cell proliferation, differentiation, and apoptosis. Down-regulation of methyltransferases enzymes and reduction of DNA methylation have been stated as epigenetic effects of cadmium. Furthermore, increasing intracellular free calcium ion levels induces neuronal apoptosis in addition to other deleterious influence on the stability of the genome.

  • Objective : This study examined psychiatric characteristics of wounded persons of Daegu subway fire accident occurring in February 2003 after six years. Methods : 103 wounded persons completed psychometric measures at 2 months and 6 years after the accident. Changes of psychiatric symptoms were compared and factors affecting post-traumatic stress disorder (PTSD) seriousness were examined. Results : In Minnesota Multiphasic Personality Inventory, the scores of Psychopathic Deviate (Pd), Masculinity/ Femininity (Mf), Social Introversion (Si) scales were significantly changed over time. The scores of Symptoms Checklist-90-Revision subscales were mostly decreased over time, however, paranoid ideation (PAR) subsclae scores were not significantly changed over time. In all of the State-Trait Anxiety Inventory (STAI)-State, Beck Depression Inventory, Impact of Event Scale, and PTSD Checklist-Civilian, mean scores at 6 years after the accident were significantly lower than those at 2 months after the accident. However, STAI-Trait score was not significantly changed over time. Total seriousness of PTSD was found to be affected by quality of sleep. Conclusions : Psychiatric symptoms of subjects were largely improved over time, but distrust and doubt of others were continued. In addition, the wounded persons suffered from sleep problems. Therefore, early and continuous interventions of public institutions and public health specialists are needed for the wounded persons with chronic psychiatric disorders.

  • Benign prostatic hyperplasia (BPH) is one of the major diseases of the urinary system in older men. WSY-0702 is the extracted from the traditional medicinal plant; Seoritae, and it has effects of anti-obesity, chronic cervical pain, and anti-oxidant. The present study aimed to investigate the therapeutic potential of WSY-0702 in the prevention and treatment of BPH. Several parameters including inflammatory mediators, hormones, and oxidative stress (OS) have been considered to play a role in the development of BPH. Prostate tissue damage and OS may lead to compensatory cellular proliferation with resulting hyperplastic growth. An in vitro study showed that proliferation inhibited the human prostate epithelial cell line RWPE-1 in a dose-dependent manner. In cell line, the cell cycle at the G2/M and G0/G1 phase and downregulated the expression of CyclineB1 (CCNB1) and CyclineD1 (CCND1). In addition, we measured the $H_2O_2$-induced OS damage using RWPE-1 cells. We examined the relative expression of protein involved in the regulation of prostate apoptosis: transforming growth factor (TGF)-${\beta}$, a negative growth factor able to induced prostate apoptosis under physiological conditions. These results suggest that WSY-0702 that can inhibit the growth of prostate epithelial cell by a mechanism that may involve arresting the cell cycle and downregulating CCNB1 and CCND1 expression. In addition, WSY-0702 exposure resulted in significant protective effects in $H_2O_2$-stressed PWPE-1 cells by reduction in TGF-${\beta}$ levels.

  • The purpose of this article is to oversee the theory of Chimibyeong(治未病). The aim of Chimibyeong theory is to prevent disease from occuring, worsening, being delivered and so on. In many books, the word Chimibyeong was used as an alternative name for Yangsaeng(養生) or used as a term of preventing a disease or used as a word meaning treating disease in the early stage. But after the period of "Nangyeong(難經)", people extend the meaning of Chimibyeong to all stages of a disease covering the healthy stage, the early stage, the progressive, and the recovery stage of a disease. Especially in urgent cases when pathogenic factor[邪氣] attacks patient to critical situations, it is also regarded as one way of Chimibyeong to repel pathogenic factor out as soon as possible with proper medicines. These days people suffer from increasing mental stress, lack of rest and human relationships, environmental pollution and chronic diseases and so on, and the situation will grow worse. Many governments employ the health policy where preventing disease takes the highest priority because by doing that they can save a huge budget and minimize the economic and social disorder. In this circumstances the idea of pursuing prevention in the theory of Chimibyeong will help people to maintain healthy conditions.

  • Enteral nutritional support has been used via tube feeding for dysphagic stroke patients. We performed long and short term trials to evaluate the effects of commercial enteral nutritional supports on nutrition and health in stroke patients (mRS = 3~5) and quality of life in their caregivers. For a long term study, we recruited chronic (${\geq}$ 1 yrs) stroke patients (n = 6) and administered them 6 cans/day (1,200 kcal) of the commercial enteral formula N for 6 months according to IRB-approved protocol. We collected peripheral blood at 0, 2, 4 and 6 months. For a short term study, we recruited acute (${\leq}$ 3 months) stroke patients (n = 12) and randomly administered them two different commercial enteral formulas, N or J, for 2 weeks. We collected their blood at 0, 4, 7 and 14 day of the administration. Blood samples were analyzed to quantify 19 health and nutritional biomarkers and an oxidative stress biomarker, malondialdehyde (MDA). In order to evaluate quality of life, we also obtained the sense of competence questionnaire (SCQ) from all caregivers at 'before' and 'after trials'. As results, the enteral formula, N, improved hemoglobin and hematocrit levels in the long term trial and maintained most of biomarkers within normal ranges. The SCQ levels of caregivers were improved in the long term treatment (P < 0.05). In a case of the short term study, both of enteral formulas were helpful to maintain nutritional status of the patients. In addition, MDA levels were decreased in the acute patients following formula consumption (0.05 < P < 0.1). Most of health and nutrition outcomes were not different, even though there is a big difference in price of the two products. Thus, we evaluate the formula N has equal nutritional efficacy compared to the formula J. In addition, long term use of enteral formula N can be useful to health and nutrition of stroke patients, and the quality of life for their caregivers.

  • The hemodialysis patients with chronic renal disease have experienced negative emotions, especially depression among with physical, social, and psychological changes. Based upon a stress-coping theory, group imago psychotherapy which can induce effective coping through self awareness and positive emotional responses is implemented to the hemodialysis patients. The effects of the imago psychotherapy in regards to comfort and depression are studied here. Group imago psychotherapy was performed on forty-three subjects(twenty subjects in the experimental group and twenty-three subjects in the control group). The results of the study were as follows. After being given group imago psychotherapy, the comfort scores of the experimental group were significantly higher than those of the control group (F=15.33, p= .003). Moreover, after being given treatment, the depression scores of the experimental group were significantly lower than those of the control group (F=9.14. p=.0044). Specifically, the scores on comfort in the experimental group under emotion-focused coping style were significantly higher than those of the control group (F=18.59, p= .0002). The mean difference on comfort scores in the experimental group under problem - focused coping style was higher than that of the control group. But their scores were not significant (F=0.19, p= .6729). The scores on depression in the experimental group under emotion-focused coping style were significantly lower than those of the control group (F=14.62, p= .0006). The mean difference on depression scores in the experimental group under problem - focused coping style was much lower than that of the control group. But their scores were not significant (F=0.31, p=.5947). There was a significant positive correlation between comfort and depression variables. After group imago psychotherapy the hemodialysis patients recognized positive changes in emotional reponses, self awareness, self control, ease of mind, and felt overall more relaxed. Imago psychotherapy is a nursing intervention which as this study has shown can improve to comfort. The results of this study can be applied to general nursing practices. In the view of holistic nursing, the development of the nursing practice combined with imago psychotherapy will contribute to the enlargement of the nursing field with conventional nursing practices.

  • Objectives : In this paper, lung atrophy syndrome[肺痿] in 『Huangdineijin(黃帝內經)』 and 『Jinguiyaolue(金匱要略)』 were compared, followed by examining its relation with upper wasting thirst[上消]. Also, ways in which psychological factors that contribute to lung atrophy syndrome could cause upper wasting thirst were studied. Methods : Verses from 『金匱要略·肺痿肺癰咳嗽上氣病脈證治』 and 『素問·痿論』 were analyzed based on various annotators's opinions to determine the cause and mechanism of lung atrophy syndrome and its relationship with upper wasting thirst. Results : In 『Jinguiyaolue(金匱要略)』, lung atrophy syndrome is described as the heat of the upper body entering the lungs to dry it out. The description in 『Suwen(素問)』 differs in that it accompanies atrophy symptoms, but the mechanism is the same. Lung atrophy syndrome in 『Jinguiyaolue』 could come from wasting thirst, while wasting thirst can be accompanied in deficiency caused by chronic lung atrophy syndrome. Heat in the lungs is caused by psychological factors where the person has lost its subject of possession or was unable to attain what was desired. When expanded to include heart atrophy syndrome[心痿] and lung atrophy syndrome[肝痿], the reason for upper wasting thirst could include immense sadness or excessive indulgence in pleasure due to unmet desires. Conclusions : Although diabetes and wasting thirst are not identical, application of wasting thirst pattern differentiation to diabetes treatment and management could lead to tailored treatment of each patient. Moreover, the five zhang pattern differentiation from the 『Suwen(素問)』 could increase treatment efficacy when applied to conditions caused by stress and emotional disorder, which are increasingly playing larger roles in causing wasting thirst, or diabetes.

  • Purpose. This study reported on body type perception of people aged ${\geq}19years$, regardless of gender, and on its association with disease morbidity and the quality of life and aimed to observe the effects of stress on body weight perception, disease morbidity, and the quality of life. Methods. The data from 218,899 persons aged ${\geq}19years$ who were respondents to the 2010 Community Health Survey were finally analyzed. A designated program was used to perform complex sample analysis; chi-square test was carried out to determine body type perception by the general characteristics and disease status and analyze health-related behavior and weight control behavior by body type perception, and multiple logistic regression was used to observe the effects of body type perception on mental health and the quality of life. Results. 34.9% of all the respondents misperceived their body type and females were more likely to misperceive their body type. The older they were, the more poorly they perceived their body type; those perceiving their body type poorly were significantly more susceptible to both hypertension and diabetes. When correction was made in relation to gender, age, and so on, those perceiving their body type excessively were more susceptible to hypertension (1.43[1.367-1.050]) and diabetes morbidity (1.36[1.294-1.428]). Body type perception affected the quality of life: the respondents perceiving their body type poorly (0.91[0.884-0.940]) or excessively (0.75[0.720-0.770]) showed lower quality of life than those perceiving their body type correctly. Conclusions. Distorted body type perception affected disease morbidity and the quality of life: the respondents excessively perceiving their body type were significantly more susceptible to both hypertension and diabetes and those perceiving their body type excessively or poorly showed lower quality of life than those perceiving it correctly. It is therefore necessary to make multilateral efforts to cultivate correct body type perception.

  • The purpose of this study was to investigate dietary behaviors and health-related lifestyles of adult visitors at a public health center in Gyeonggi urban area. A survey using questionnaire was conducted with 949 visitors at Seongnam public health centers from June to August, 2012. The data from 905 respondents were analyzed by gender, consisting of 322 males and 583 females, and age group, consisting of 243 low-age group (LA), 312 middle-age group (MA), 350 high-age group (HA), aged 20 to 30 years, 31 to 50 years, and 51 to 69 years, respectively. Average Body Mass Index was 23.0, which increased with age, and education level was high in LA. 59.0 percent of the subjects had various diseases, and the incidence of hypertension was the highest, followed by allergy, hyperlipidemia, diabetes mellitus, joint rheumatism. Incidence rates of chronic disease increased with age, which were lower than those from 2011 Korea National Health and Nutrition Examination Survey (KNHANES). Weekly drinking frequency rate and smoking rate decreased with age, and exercise performing rate was high at male and HA, which showed the same tendency as KNHANES. Female and HA showed more healthy dietary behaviors such as restricting salt, sugar, oily foods, foods containing food additives, calorie, caring for balanced diet, and referring to nutrition label. Subjects chose stress as the first factor, followed by diet, exercise, etc., among 13 suggested factors which strongly influence on human's life-span. In general, public health center visitors, especially female and HA, showed better dietary behaviors and health-related lifestyles compared with KNHANES.
