  • Biomarkers are characteristic biological properties that can be detected and measured in a variety of biological matrices in the human body, including the blood and tissue, to give an indication of whether there is a threat of disease, if a disease already exists, or how such a disease may develop in an individual case. Along the continuum from exposure to clinical disease and progression, exposure, internal dose, biologically effective dose, early biological effect, altered structure and/or function, clinical disease, and disease progression can potentially be observed and quantified using biomarkers. While the traditional discovery of biomarkers has been a slow process, the advent of molecular and genomic medicine has resulted in explosive growth in the discovery of new biomarkers. In this review, issues in evaluating biomarkers will be discussed and the biomarkers of environmental exposure, early biologic effect, and susceptibility identified and validated in epidemiological studies will be summarized. The spectrum of genomic approaches currently used to identify and apply biomarkers and strategies to validate genomic biomarkers will also be discussed.

  • This study was designed to investigate the characteristics of corneal ulcers in dogs with chronic kidney disease (CKD). Medical records of dogs that had been diagnosed with corneal ulcers and chronic kidney disease at Haemaru Referral Animal Hospital between April 1, 2011 and March 31, 2016 were investigated. A control group was randomly selected during the same time period. This group included patients with corneal ulcers but no evidence of systemic disease. The mean healing time of superficial corneal ulcers in the CKD group was 21.0 ± 15.0 days. This was a significantly longer healing time than was observed in the control group (11.0 ± 6.6 days, p = 0.019). The incidence rates of uveitis and keratoconjunctivitis sicca in the CKD group were significantly higher than in the control group (p = 0.000 and p = 0.026, respectively). Additionally, non-healing ulcers had significantly elevated white blood cell counts, while those with healing ulcers had WBC counts within the normal range in CKD group (p = 0.000). This study revealed that corneal ulcers in CKD patients would be delayed epithelial healing process and accompanied by ocular disease which affected to corneal healing compared to non-CKD patients.

  • Background/Aims: Elderly patients (${\geq}80years$) with colorectal cancer (CRC) tend to avoid active treatment at the time of diagnosis despite of recent advances in treatment. The aim of this study was to determine treatment propensity of elderly patients aged ${\geq}80years$ with CRC in clinical practice and the impact of anticancer treatment on overall survival (OS). Methods: Medical charts of 152 elderly patients (aged ${\geq}80years$) diagnosed with CRC between 1998 and 2012 were retrospectively reviewed. Patients' clinical characteristics, treatment modalities received, and clinical outcome were analyzed. Results: Their median age was 82 years (range, 80 to 98). Of 152 patients, 148 were assessable for the extent of the disease. Eighty-two of 98 patients with localized disease and 28 of 50 patients with metastatic disease had received surgery or chemotherapy or both. Surgery was performed in 79 of 98 patients with localized disease and 15 of 50 patients with metastatic disease. Chemotherapy was administered in only 24 of 50 patients with metastatic disease. Patients who received anticancer treatment according to disease extent showed significantly longer OS compared to untreated patients (localized disease, 76.2 months vs. 15.4 months, p = 0.000; metastatic disease, 9.9 months vs. 2.6 months, p = 0.001). Along with anticancer treatment, favorable performance status (PS) was associated with longer OS in multivariate analysis of clinical outcome. Conclusions: Elderly patients aged ${\geq}80years$ with CRC tended to receive less treatment for metastatic disease. Nevertheless, anticancer treatment in patients with favorable PS was effective in prolonging OS regardless of disease extent.

  • Objectives : This study was to analyse the reasons for the early termination of our clinical trials that were to know the influences of Tai-chi on non-motor symptoms of Parkinson's disease. Methods : We stopped the primary study of Tai-chi to observe the changes of non-motor symptoms of Parkinson's disease. So we carried out the survey to our participants of clinical trials. We conducted the survey about the patient's characteristics of usual exercise, experience of Tai-chi, appropriate time allocation, difficulties of proceeding the program and patient's opinion for the improvement of education. And the 4 questions about the contributiveness of Tai-chi for the Parkinson's disease, usability of supplied references, difficulties and time allocation of education were using the questionaries form of 5-point scale(Likert scale). Results : The results of survey showed that the benefits of Tai-chi program for the improvement of symptoms was $3.15{\pm}0.89$ and difficulty of lecture was $3.76{\pm}1.09$. 41% of participants answered that the motions of the Tai-chi is difficult to follow and 17% of participants felt the imbalance during the motion of Tai-chi. Conclusions : Participants replied that the Tai-chi is hard for the patients of Parkinson's disease and the time for the education was too short to keep doing exercise. Thus we have plan to educate the patients of Parkinson's disease with Tai-chi program consists of easier motion by developing ourselves or searching previous studies.

  • Objectives : The objective of this review is to introduce the basic concepts on the febrile disease in the Mongolian Traditional Medicine(MTM). Methods : We comprehensively reviewed related textbooks in Mongolian and articles searched from China National Knowledge Infrastructure(CNKI) on febrile disease about MTM and summarized the pathophysiologic basis of, and treatment principles in MTM. Results and Conclusions : 1. In MTM, there are basic concepts such as theory of Arga-Bilig, theory of five elements, theory of three elements(人體三素), theory of seven constitutions and three discharges(七元三濊). Most of all, theory of three elements, which is about the basic elements of human body in MTM, is important fundamental notions for explaining human physiology and pathology. In MTM, It is explained that the imbalance of three elements, namely khii, shar, bad-kan is the root of all disease. Especially, febrile disease is treated by suppressing activated shar and blood(血液), which have fire characters, and managing various additional symptoms by balancing three elements and eliminating miasma(邪氣), inappropriate substances such as bile water(shar yc, 黃水) or blood stasis(惡血) simultaneously. 2. In MTM, both of internal treatment modalities(various medicinal therapy) and external treatment modalities(physical therapy) have been used for febrile disease. Food therapy and life style modification also have been recognized as important treatment methods. These aspects correspond to wholism theory of Korean Traditional Medicine(KTM). Further studies about details of each treatment methods will discover new applicable treatment method and make broaden the external boundaries of the KTM.

  • Objective: The outbreak of Middle East Respiratory Syndrome (MERS) started in South Korea in May 2015 and the end of crisis was declared in December 2015 by Korea Centers of Disease Control and Prevention (KCDC). However, Zika virus emerged in less than 2 months following MERS and showed higher mortality than other countries. This study is to assess the current prevention system of overseas infectious diseases, based on MERS and Zika virus outbreak and to suggest effective response system for the future. Methods: We conducted two surveys on medical specialists working at tertiary general hospitals regarding the effectiveness of responding system by KCDC against MERS and Zika virus and education in individual medical institutions using 5-Likert points. Response system was examined in three different periods as initial period, spreading period, and post disease period. Results: Although medical specialists received the notifications in initial period, no practical prevention was proven to be placed in responding stage by medical facilities (averagely 3.5/5 points in total and sub-analyses). During spreading period, there were several academic seminars conducted, which were evaluated as helpful. In post disease period, all answered that there were changes on patient treatment in all medical facilities, with mainly report system and the treatment regulations in case of suspicious patients for infection. Only 49% respondents answered positive on the possibility of initial responses. For questionnaire items regarding Zika virus, all answered that there were notifications prior to the first outbreak of the infected patient. Eighty% of respondents were aware of 'the Guideline system for traveling to dangerous areas', and answered that the system was moderately effective (averagely 3.8/5 points in total). For the effectiveness of prevention measures for foreign novel disease by KCDC, the average point was 3.0 in both of total and sub-analyses. Conclusion: There is not enough response system to prevent infectious disease in medical institutional and governmental levels in Korea. It would warrant the modification of overall medical system to improve preventive measures for initial spread of such diseases.
