Herniation after harvesting of deep circumflex iliac artery (DCIA) flap is a known but not a common complication. It occurs about 2.8 to 9 % according to the literatures and can proceed to a more severe complication such as bowel obstruction. There are several factors that exacerbate the risk: surgical factors, operator factor, and patient factors. Surgical factors include large anatomical defect and denervation of related muscles. Operator factor stands for unpunctual suture technique. Patient factors represent obesity, diabetes, pulmonary disease, smoking habits, and so on. Thus, herniation might occur regardless of meticulous suture. Herein, we would like to report two cases of herniation after DCIA flap harvesting and repaired by Lichtenstein tension-free hernioplasty with literature review.
Ubiquitin signaling regulates virtually all aspects of eukaryotic biology and dynamic processes in which protein substrates are modified by ubiquitin. To regulate these processes, deubiquitinating enzymes (DUBs) cleave ubiquitin or ubiquitin-like proteins from these substrates. DUBs have been implicated in the pathogenesis of cancer, leading to the development of increasing numbers of small-molecule DUB inhibitors. On the other hand, recent studies have focused on the function of DUBs in metabolic diseases such as obesity, diabetes, and fatty liver diseases. DUBs play a positive or negative role in the progression and development of metabolic diseases. Their involvement in cell pathology and regulation of major transcription factors in metabolic syndrome has been examined in vitro and in animal and human biopsies. UCH, USP7, and USP19 were linked to adipocyte differentiation, body weight gain, and insulin resistance in genetic or diet-induced obesity. CYLD, USP4, and USP18 were found to be closely associated with fatty liver diseases. In addition, these liver diseases were accompanied by body weight change in certain cases. Collectively, in this review, we discuss the current understanding of DUBs in metabolic diseases with a particular focus on obesity. We also provide basic knowledge and regulatory mechanisms of DUBs and suggest these enzymes as therapeutic targets for metabolic diseases.
The Camella japonica flower(CJF) extract was studied for their anti-angiogenenic and anti-cell adhesion effect. CJF-extract inhibited the tube formation on human umbilical vein endotherial cells(HUVEC) with butanol extract by 70.2%, acetone extract by 54.2%, ethyl acetate extract by 37.0%, chloroform extract by 21.2%. Cell adhesion molecules were effectively suppressed at different concentration of CJF at 50, 100, 200 ug/well such as for intercellular adhesion molecule(ICAM) by 5.9%, 29.4% and 52.9%, for vascular cell adhesion molecule(VCAM) by 12.5%, 43.8% and 62.5%, for E-selectin by 7.1%, 21.4% and 35.7%, respectively. Signal molecules of vascular endotherial growth factor receptor 2(VEGFR2), ${/beta}$-catenin and PI3K are inhibited by different concentration of CJF at 10, 20 and 30 ${\mu}g/mL$ with western blot. Angiogenesis will be inhibited with suppressing NF-kB molecule resulted in signal molecules blocked by CJF. CJF will be useful materials for treatment of angiogenesis related diseases such as cancer, metastasis, rheumathioid arthritis and obesity.
Anti-angiogenesis and anti-cell adhesion effects were investigated with different dose of Camellia japonica leaf (CJL) extract for applying anti-cancer, anti-metastasis and anti-obesity. Cytotoxicity on HUVECs was very low at 200 ug/mL of CJL-extract. Anti-angiogenic ratio at increasing dose of 1.5 ug/mL, 3.0 ug/mL, 15 ug/mL and 30 ug/mL was showed 30.7%, 38.5%, 53.8%, and 70.0%, respectively. Also, anti-cell adhesion effect at concentration of $50{\mu}g{/well},\;100{\mu}g{/well}\;and\;200{\mu}g{/well}$ was expressed on E-selectin by 46.7%, 66.7%, and 86.76%, on VCAM-1, 23.0%, 61.5%, and 84.6%, and on ICAM-1, 11%, 55.5%, and 88.8%, respectively. For inquiring anti-angiogenesis mechanism, when western blot was performed with different dose of CJL extract, signal molecules of VEGFR-2, $\beta$-catenin and PI3-K were suppressed. As the signal transduction from VEGFR-2, $\beta$-catenin and PI3-K to NF-${\kappa}$B was interupted, angiogenesis could not be occurred causing not activated NF-kB. C. japonica leaf (CJL) is a useful herb for developing therapeutics of angiogenesis related diseases such as cancer, metastasis, rheumathioid arthritis and obesity.

Codonopsis lanceolata (C. lanceolata) has been widely used in East Asia as a traditional medicine to treat various diseases such as bronchitis, convulsions, cough, obesity, and hepatitis. C. lanceolata belonging to Campanulaceae contains bioactive compounds such as polyphenols, saponins, and steroids. However, despite the pharmacological significance of C. lanceolata, the genetic information of this plant is limited and there are few studies of its transcriptome. In this study, we constructed a unigene set of C. lanceolata using Pac-Bio sequencing. Furthermore, the reads generated from Pac-bio and Illumina sequencing were mixed and assembled using rnaSPAdes. All genes involved in the triterpenoid pathway, a major bioactive compounds of C. lanceolata, were searched from the two unigene sets and the expression profiles of these genes were analyzed. The results showed that lupeol, beta-amyrin, and dammarenediol synthesis genes were activated in the leaves and roots of C. lanceolata. In particular, the expression of genes related to lupeol synthesis was relatively high, suggesting that the main triterpenoid of C. lanceolata is lupeol. Transcriptome studies related to lupeol synthesis in C. lanceolata have been rarely reported. Lupeol has been reported to have pharmacological effects such as anti-inflammatory, anti-cancer, and anti-bacterial. This study suggests the importance of C. lanceolata as a lupeol producing plant.
Purpose: This study investigated weight status in survivors of childhood acute lymphocytic leukemia (ALL) and identified related factors. Methods: A retrospective review of the electronic medical records of survivors of childhood ALL (n=230) was conducted. We analyzed the survivors' characteristics, including sex, age, weight status at diagnosis, central nervous system involvement, risk classification, length of treatment, radiation therapy, and hematopoietic stem cell transplantation. Analysis of variance and the chi-squared test were applied to investigate influencing factors. Results: The weight status distribution was as follows: 23 individuals (10.0%) were classified as underweight, 151 individuals (65.7%) were healthy weight, and 56 individuals (24.3%) were overweight/obese. Age at diagnosis (F=10.03, p<.001), weight status at diagnosis (x2=43.41, p<.001), and risk classification (F=10.98, p=0.027) showed significant differences among the weight status groups. Survivors who were older at diagnosis and those in the very high-risk category had a higher likelihood of experiencing underweight status during their survivorship, while survivors who were overweight/obese at diagnosis were more likely to remain overweight/obese at the time of survival. Conclusion: Considering the potential health implications related to an unhealthy weight status in survivors of ALL, it is imperative to undertake early identification and implement interventions for at-risk individuals.
The consumer perception on health and food habit, the experience of health food use and the discrimination between health food and drug of Korean consumer were surveyed by using a questionnaire containing 15 items in order to obtain the basic data for the assessment of the benefit and risk of health foods in Korea. A total of 1,000 people over 20 years of age living in Seoul and the vicinities were interviewed and asked to fill out the questionnaire during the period from the October 1995 to the February 1996. Among the 882 answers collected, 23 was incomplete data, and 859 answers were used for the statistical analysis by using SAS program. The perception of Korean consumer on health and food habit indicated that food habit was considered the most important factor for the maintenance of health, as appeared in 39.8% of the subjects, among which 93.9 % believed that food habit could cause disease, and 97.1% believed that disease could be cured by changing food habit. The most worried disease was cancer (30.6%), degenerative diseases (14.1%), diseases by accident (12.6%) and obesity (10.0%). The disease which likely to be caused by food habit was diabetes (35.6%), obesity (22.4%), high blood pressure (12.8%), constipation (12.7%) and cancer (7.9%). The disease which was believed to be cured by changing food habit was diabetes (40.1%), obesity (25.9%), constipation (16.5%), high blood pressure (7.4%) and cancer (3.3%). It appeared that the people had a perception that food habit was highly related with diabetes and obesity, but less with cancer which was mostly worried.
Objectives : The aim was to investigate the characteristics of low dose effect and non monotonic dose responses(NMDRs) and to predict the influence it might have on the health and medicine, traditional Korean medicine. Methods : By investigating recently published major literatures related to low dose effect and NMDRs, the definition, mechanism, major related fields, and the influence on public health and medicine has been categorized and summarized. Results : Although there are still heated debates about the definition of low dose, it implies the biological responses in environmental exposure level and the NDMDRs means the nonlinear relationship between the dose-response in the slope sign change. Also, it implies the new form of the curve showing a U, reverse U shape, and the slop sign constantly changing showing various forms. This mechanism is because the two acceptor shows opposing effects to toxic materials and the affinity is different along with the numerical value that increase and decrease being different. These characteristics generally appear in endocrine disrupters such as bisphenol A, agricultural pesticides, metal, and radiation. The research field in the public health and medical treatment is obesity, problems in metabolism, growth hormone treatment, climacteric treatment, breast cancer, intake of Korean traditional medicine for pregnancy, menopause and phytoestrogen. Conclusions : As a result of discussing implications, NMDRs is a particular effect in low dose and heated debates surround this response, research is being conducted surrounding the field of obesity, problems in metabolism, growth hormone treatment, climacteric treatment, breast cancer, intake of Korean traditional medicine for pregnancy, menopause, and phytoestrogen. More research and interest in needed as it can have a massive influence in the public health and medicine.
Objectives: An investigative effort was made to provide basic data upon which effective public health education can be constructed for schools. Methods: The research was made by delivering self-administered questionnaires to 536 men and women with unknown names from a national university during 1-month period on September of 2004. The questionnaire items included preventive attitudes, interests, anxiety, health behavior, consciousness, etc. centering upon life-style related diseases. Results and Conclusions: The preventive attitudes against life-style related diseases was of a higher level in female than male students, The smaller number of students had knowledge of the definition of life-style related diseases, willingness to learn, and gathered information on them. The number of students who had anxiety about them was also small and as low as 54.3% of students were willing to undertake periodic health examination. A great variation ranging from 4.7% to 81.7% was shown in the accuracy rate of answers on the questions asking about three leading causes of death, overconsumption of dietary salt, obesity, diabetes, hypercholesterolemia and colon cancer. With regard to health behaviors, a smaller number of students were involved in health behaviors. On the other hand, $25.7{\sim}35.1%$ of students had everyday exercises and breakfasts, 65.5% had no tobacco use. The study results showed that the survey subjects had deficient knowledge as well as a low level of preventive attitudes and interests against life-style related diseases. Moreover, their health behavior and health consciousness were undesirable apart from their low rates of taking periodic health examinations. Accordingly, the college students should be encouraged to take health education and to make more effective the existing health education in the university.
It is important to identify modifiable risk factors for breast cancer, because the breast cancer is one of the major causs of mortality among women. Some reported that obesity is a risk factor for breast cancer, but the results are not constant. Many risk factors are related to the duration of estrogenic stimulation of the breast. In general, early menarche and late menopause are positive risk factors. Human breast cancer has different characteristics according to the status of menopause(premenopause and postmenopause). In premenopausal women, about 60% of circulating estrogen is from the ovaries in the form of estradiol, and the remaining 40% is estrogen formed primarily in the adipose(fat) tissue via aromatization of androstenedion from the adrenal glands. After menopause this adipose cell production of estrone is the main source of estrogens and the level of estrone is maintained approximately at premenopausal levels. This study was undertaken to determine the role of body size and body mass index by status of menopause in development of breast cancer using retrospective case/control study. From March 1991 to February 1997 at the Wonkwang University Hospital, the breast cancer cases(n=72) and controls(n=86) were selected. By statistical analysis method, regression analysis, paired T-test and multiple logistic regression were done to estimate the influenced factors same as height, weight, BMI, age at menarche and age at menopause. The following results were obtained : 1. In premenopausal women, age at menarche was showed comparatively high correlation coefficients and BMI was described prominently highly in postmenopause. 2. At the results of multiple regression analysis, age at monarch, BMI and weight were showed as significant variables. In this method, critical factor ($R^2$) was 0.054. 3. Paired samples T-test was undertaken to test mean difference between two groups of cases and controls. The result of test performance showed a significant difference. 4. In comparison with women whose weight less than 50 kg, the ORs for the upper 5th group was 1.82(95% confidence interval). The heaviest women had a higher risk(OR=1.14, 95% confidence interval $1.12{\sim}1.31$, p=0.005). Higher body mass index was significantly associated with increased risk of premenopausal breast cancer (OR=1.01, 95% confidence interval $1.08{\sim}l.18$, p=0.05).
