作者： soo YEON KIM SUN YOON soo mi kwon KYE sooK PARK YANG CHA LEE-KIM Graduate School of Human Environmental Science Department of Food and Nutrition College of Human Ecology Yonsei Health Center Yonsei University 134 Shinchon-dong Sudaemun-ku 120-749 Seoul Korea

Objective To evaluate the effect of 3-month kale （Brassica oleracea acephala） juice supplementation on coronary artery disease risk factors among hypercholesterolemic men. Methods Thirty-two men with hypercholesterolemia （〉 200 mg/dL） were recruited after annual health examinations among the faculty and staff at university. The subjects consumed 150 mL of kale juice per day for a 12-week intervention period. Dietary and anthropometric assessments were performed and blood samples were collected to evaluate biochemical profiles before and after supplementation. Results Serum concentrations of HDL-cholesterol, and HDL- to LDL-cholesterol ratio were significantly increased by 27% （P〈0.0001） and 52% （P〈0.0001）, respectively. The LDL-cholesterol concentration and the atherogenic index were significantly reduced by 10% （P=0.0007） and 24.2% （P〈0.0001）, respectively without affecting body mass index, waist and hip circumferences, or nutrient intakes after three months of supplementation. While there was no difference in the concentration of malondialdehyde, significant increase in glutathione peroxidase activity （P=0.0005） were accompanied by a significant increase in the serum selenium level （P=0.0132）. It was also found that the responses of these risk factors to kale juice administration were dependent on smoking status. Conclusion Regular meals supplementation with kale juice can favorably influence serum lipid profiles and antioxidant systems, and hence contribute to reduce the risks of coronary artery disease in male subjects with hyperlipidemia.

Asian Journal of Andrology 2015年第3期17卷 487-492页

作者： min Ji Choi Kang-Moon Song Jin-mi Park mi-Hye kwon Ki-Dong kwon soo-Hwan Park Dong-soo Ryu Ji-Kan Ryu Jun-Kyu Suh Department of Urology National Research Center for Sexual Medicine Inha University School of Medicine Incheon 400-711 Korea Department of Urology Changwon Samsung Medical Center Changwon 630-522 Korea Inha Research Institute for Medical Sciences Inha University School of Medicine Incheon 400-711 Korea

Transforming growth factor-β1 （TGF-β1） has been identified as one of the most important fibrogenic cytokines associated with Peyronie＇s disease （PD）. The mothers against decapentaplegic homolog 7 （SMAD7） is an inhibitory Smad protein that blocks TGF-J3 signaling pathway. The aim of this study was to examine the anti-fibrotic effect of the SMAD7 gene in primary fibroblasts derived from human PD plaques. PD fibroblasts were pretreated with the SMAD7 gene and then stimulated with TGF-β1. Treated fibroblasts were used for Western blotting, fluorescent immunocytochemistry, hydroxyproline determination, and terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling assays. Overexpression of the SMAD7 gene inhibited TGF-β1-induced phosphorylation and nuclear translocation of SMAD2 and SMAD3, transdifferentiation of fibroblasts into myofibroblasts, and quashed TGF-β1-induced production of extracellular matrix protein and hydroxyproline. Overexpression of the SMAD7 gene decreased the expression of cyclin D1 （a positive cell cycle regulator） and induced the expression of poly （ADP-ribose） polymerase 1, which is known to terminate Smad-mediated transcription, in PD fibroblasts. These findings suggest that the blocking of the TGF-β pathway by use of SMAD7 may be a promising therapeutic strategy for the treatment of PD.

引用

Chinese Journal of Integrative Medicine 2017年第5期23卷 338-344页

作者： Ju Ah Lee Jeeyoun Jung mi mi Ko Myeong soo Lee Korean Medicine Fundamental Research Division Korea Institute of Oriental Medicine Daejeon 305-811 Republic of Korea Clinical Research Division Korea Institute of Oriental Medicine Daejeon 305-811 Republic of Korea

Objective： To evaluate the consistency of patterns and pattern identification（PI）, and the improvement in the diagnosis of blood stasis after the standard operating procedures（SOPs） were enhanced by using a diagnostic flowchart. Methods： A total of 358 subjects who were admitted by the Jaseng Hospital of Korean Medicine between June 2013 and December 2014 were included in the study. Each patient was independently diagnosed by two experts from the same department. In 2014, the SOPs included the use of a diagnostic flowchart for each indicator. Inter-observer consistency was assessed by simple percent agreement and by the kappa and AC1 statistics. Results： The improvements in inter-observer agreement for the indicators（for al patients） and PI were greater in 2014 than in 2013. In 2013, the j-value measure of agreement between the two experts ranged from ＂poor＂（κ=–0.051） to ＂good＂（κ=0.968）. The AC1 measure of agreement between the experts was generally high for the indicators and ranged from –0.010 to 0.978. In most cases, agreement was considerably lower when it was assessed by the j-values compared with the AC1 values. In 2014, the j-value measure of agreement on the indicators（for the subjects） general y ranged from poor to good, with the values ranging from –0.007 to 0.994. Moreover, the AC1 measure of agreement between the experts was general y high for al of the indicators and ranged from ＂moderate＂（AC1=0.408） to ＂excel ent＂（AC1=0.996）. Conclusions： In four examinations, there was moderate agreement between the clinicians on the PI indicators of blood stasis. To improve clinician consistency（e.g., in the diagnostic criteria used）, it is necessary to analyse the reasons for inconsistency and to improve clinician training.（Trial registration No. KCT0000916）

Probability mass first flush evaluation for combined sewer discharges

引用

Journal of Environmental Sciences 2010年第6期22卷 915-922页

作者： Inhyeok Park Hongmyeong Kim soo-kwon Chae Sungryong Ha Department of Urban Engineering Chungbuk National University Ecowiz Corporation Cheongju School of Human & Environmental Sciences Eulji University

The Korea government has put in a lot of effort to construct sanitation facilities for controlling non-point source pollution. The first flush phenomenon is a prime example of such pollution. However, to date, several serious problems have arisen in the operation and treatment effectiveness of these facilities due to unsuitable design flow volumes and pollution loads. It is difficult to assess the optimal flow volume and pollution mass when considering both monetary and temporal limitations. The objective of this article was to characterize the discharge of storm runoff pollution from urban catchments in Korea and to estimate the probability of mass first flush （MFFn） using the storm water management model and probability density functions. As a result of the review of gauged storms for the representative using probability density function with rainfall volumes during the last two years, all the gauged storms were found to be valid representative precipitation. Both the observed MFFn and probability MFFn in BE-1 denoted similarly large magnitudes of first flush with roughly 40% of the total pollution mass contained in the first 20% of the runoff. In the case of BE-2, however, there were significant difference between the observed MFFn and probability MFFn.

Recognition of Association Between Blood Stasis Syndrome and Traumatic Injury among Doctors of Korean Medicine:A Cross-Sectional Observation Study

引用

Chinese Journal of Integrative Medicine 2018年第4期24卷 254-259页

作者： Jeeyoun Jung mi mi Ko Ju Ah Lee Myeong soo Lee Korean Medicine Fundamental Research Division Korea Institute of Oriental Medicine Clinical Research Division Korea Institute of Oriental Medicine

Objective： To investigate the diagnostic indicators and herbal treatments for blood stasis syndrome（BSS） patients with traumatic injuries and to identify the association between BSS and traumatic injury in Korea. Methods： Two-hundred and four patients with traumatic injury were recruited from the Gangnam and Daejeon branches of Jaseng Hospital of Oriental Medicine between June 2014 and December 2014. Two independent doctors of Korean medicine（DKMs） determined the diagnosis of BSS or non-BSS based on the subjects＇ signs and symptoms. The scores assigned to BSS symptoms and DKMs＇ reasons for diagnosing BSS in patients with traumatic injury were investigated. Both medication and herbal prescription records from a 3-month period were collected for all patients diagnosed with BSS by both DKMs. Results： A total of 169 of 204（82.8%） patients received consistent diagnosis related to BSS by two DKMs. Among them, 54.4%（92 cases） were diagnosed with BSS, and 45.6%（77 cases） were not diagnosed with BSS. DKMs most frequently cited symptoms of recent traumatic injury as justifications for BSS diagnoses, and also selected pain-related indicators such as abdominal pain, sharp pain and nocturnal pain as important reasons in diagnosing BSS. In addition, an inconsistency in the pattern identification theory with respect to traumatic injury was observed. Although only 92 cases（54.4%） of patients were diagnosed with BSS, 77.6% of them were prescribed decoctions for BSS. Conclusions： DKMs considered traumatic injury could cause BSS, and utilized decoction for BSS in patients with traumatic injury without confirming a diagnosis of BSS because they assumed the main symptoms or pathologies of traumatic injury to be closely related to BSS.

AIM To determine the relationship between F-18 fluorodeoxyglucose(FDG) uptake of bone marrow(BM) on positron emission tomography/computed tomography(PET/CT) and clinical factors and to assess the prognostic value of FDG uptake of BM in gastric *** We retrospectively enrolled 309 gastric cancer patients who underwent staging FDG PET/CT and curative surgical resection. FDG uptake of primary tumor was visually classified as positive or negative FDG uptake. Mean FDG uptake of BM(BM SUV) and BM-to-liver uptake ratio(BLR) were measured. The relationships of BM SUV or BLR with clinical factors were evaluated. The prognostic values of BM SUV, BLR, and other clinical factors for predicting recurrence-free survival(RFS) and overall survival(OS) were *** Of 309 patients, 38 patients(12.3%) experienced cancer recurrence and 18 patients(5.8%) died. Patients with advanced gastric cancer, positive FDG uptake, and recurrence had higher values of BM SUV and BLR than those with early gastric cancer, negative FDG uptake, and no recurrence(P < 0.05). BM SUV and BLR were significantly correlated with hemoglobin level, neutrophil-to-lymphocyte ratio, and platelet-tolymphocyte ratio(P < 0.05). On multivariate analysis, multiple tumors, T stage, lymph node metastasis, tumor involvement of resection margin, and BLR were significantly associated with RFS(P < 0.05). T stage, lymph node metastasis, hemoglobin level, and BLR were significantly associated with OS(P < 0.05). CONCLUSION BLR on PET/CT was an independent prognostic factor for RFS and OS in gastric cancer patients with curative surgical resection.

The somatosensory system plays a crucial role in executing precise movements by providing sensory feedback （Farrer et al., 2003; Rabin and Gordon, 2004）. Somatosensory dys- function is a common problem following stroke. In partic- ular, somatosensory impairments, such as impairment in touch, proprioception, light touch, and vibration have been frequently observed （Carey et al., 1993; Sullivan and Hed- man, 2008; Tyson et al., 2008）. Patients with somatosensory dysfunction show negative effects on motor control, and it sometimes becomes difficult to perform daily activities independently.
