Dissemination of gastric cancer may usually occur by direct spread through the perigastric tissues to adjacent organ, lymphatic spread, and hematogenous spread. We report a rare case of gastric cancer with mucosal metastastic lesion on the upper esophagus that was diagnosed by endoscopy and endosonography. A biopsy of the esophageal mass was performed and the pathologic findings with immunohistochemical stain for Mucin-5AC are proved to be identical to that of gastric adenocarcinoma, suggesting metastasis from main lesion of the gastric cancer. The lesion could not be explained by lymphatic or hematogenous spread,and its metastasis mechanism is considered to be different from previous studies. We suggest that the gastroesophageal reflux of cancer cells could be one of the possible metastatic pathways for metastasis of esophagus from an adenocarcinoma of the stomach.

AIM： To examine surgical specimens of pancreas with either chronic pancreatitis or pancreatic cancer in order to study whether ductal hyperplasia and dysplasia in pancreas represent precursor lesions for pancreatic cancer. METHODS： We examined expression of Ki-67, CEA, p53, and K-ras, in the surgical specimens of pancreas with adenocarcinomas （n = 11） and chronic pancreatitis （n = 12）. Cellular proliferation was assessed by Ki-67 proliferation index using the proliferation marker Ki-67. In specimens with pancreas cancer, we divided pancreas epithelium into normal （n = 7）, ductal hyperplasia （n = 3）, dysplasia （n = 4）, and cancerous lesion （n = 11） after hematoxylin and eosin staining, Ki-67, and CEA immunohistochemical staining. In cases with chronic pancreatitis, the specimen was pathologically examined as in cases with pancreas cancer, and they were also determined as normal （n = 10）, ductal hyperplasia （n = 4）, or dysplasia （n = 5）. p53 and K-ras expression were also studied by immunohistochemical staining. RESULTS： In pancreatic cancer, the Ki-67 index was 3.73±3.58 in normal site, 6.62±4.39 in ductal hyperplasia, 13.47：1：4.02 in dysplasia and 37.03±10.05 in cancer tissue, respectively. Overall, p53 was positive in normal ducts, ductal hyperplasia, dysplasia, and carcinoma cells in 0 of 14 （0%）, 0 of 7 （0%）, 7 of 9 （78%）, and 10 of 11 （91%）, respectively, and K-ras was positive in 0 of 8 （0%）, 1 of 3 （33%）, 4 of 6 （67%）, 4 of 5 （80%）, respectively. CONCLUSION： Our results favorably support the hypothesis that ductal hyperplasia and dysplasia of the pancreas might be precursor lesions for pancreas cancer. Further evaluation of oncogenes by the molecular study is needed.

Giant choledocholithiasis treated by mechanical lithotripsy using a gastric bezoar basket

引用

World Journal of Gastroenterology 2012年第25期18卷 3327-3330页

作者： Hyun Jung Chung Seok Jeong Don Haeng Lee Jung Il Lee Jin-Woo Lee Byoung Wook Bang kye sook kwon Hyung Kil Kim Yong Woon Shin Young Soo Kim Division of Gastroenterology Department of Internal MedicineInha University School of MedicineIncheon 400-711South Korea

Mechanical lithotripsy （ML） is usually considered as a standard treatment option for large bile duct stones. However, it is impossible to retrieve oversized stones because the conventional lithotripsy basket may not be able to grasp the stone. However, there is no es- tablished endoscopic extraction method for such gi- ant stone removal. We describe a case of successful extraction of a 4-cm large stone using a gastric bezoar basket. A 78-year-old woman had suffered from upper abdominal pain for 20 d. Contrast-enhanced computed tomogram revealed a 4-cm single stone in the distal common bile duct （CBD）. Endoscopic stone retraction was decided upon and endoscopic papillary balloon dilation was performed using a large balloon. An at- tempt to capture the stone using a standard lithotripsy basket failed due to the large stone size. Subsequently, we used a gastric bezoar basket to successfully capturethe stone. The stone was fragmented into small pieces and extracted. The stone was completely removed after two sessions of endoscopic retrograde cholangio- pancreatography; each of which took 30 rain. No com- plications occurred during or after the procedure. The patient was fully recovered and discharged on day 11 of hospitalization. ML using a gastric bezoar basket is a safe and effective retrieval method in select cases, and is considered as an alternative nonoperative option for the management of difficult CBD stones.

Kale Juice Improves Coronary Artery Disease Risk Factors in Hypercholesterolemic Men

引用

Biomedical and Environmental Sciences 2008年第2期21卷 91-97页

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.

Improvement of light uniformity by lighting arrangement for standardized crop production

引用

Journal of Central South University 2014年第11期21卷 4311-4319页

作者： Lee Hwa-Soo kwon sook-Youn Lim Jae-Hyun Department of Computer Science and Engineering Kongju National UniversityCheonan 331-717 Korea

In a commercialized, fully artificial plant factory, artificial luminaire is arranged in a unified way using a general illumination theory, an actual measurement, or an empirical methodology. However, with these methods, lightings are implemented without considering specific optical characteristics of lighting or material characteristics of each component that constructs a cultivation system, resulting in an amount of light that becomes irregular. The amount of lighting is closely related with the growth and quality of crops, and the deviation between points where cultivated crops are located causes quality difference in the produced crops, thus impairing the economic feasibility of a plant factory. In this regard, a simulation to figure out an optimum lighting layout was performed. Arrangements based on the spectrum distribution of light source and reflector materials were implemented to ascertain the distance between lighting and height of lighting and gather information in the pre-treatment process to improve the uniformity of light in the plant cultivation system. Improvement of around 15% in light uniformity is achieved compared with the existing system after the simulation is carried out. This result would reduce the deviation in crop growth to make uniform quality crop production possible.

Advances in Atmospheric Sciences 2003年第3期20卷 379-384页

作者： Keon-Tae SOHN H.Joe kwon Ae-sook SUH Pusan KongjuMeteorological Research Institute//KMA National UniversityPusan609-735KoreaNational UniversityKonju314-701KoreaSeoul156-010Korea

This paper presents a study on the statistical forecasts of typhoon tracks. Numerical models have their own systematic errors, like a bias. In order to improve the accuracy of track forecasting, a statistical model called DLM (dynamic linear model) is applied to remove the systematic error. In the analysis of typhoons occurring over the western North Pacific in 1997 and 2000, DLM is useful as an adaptive model for the prediction of typhoon tracks.

作者： Shin-Heon Lee Myeong-Jin Ko Taek-Kyun Nam Jeong-Taik kwon Yong-sook Park Department of Neurosurgery College of MedicineChung-Ang UniversitySeoul 06973South Korea

Background: The relationship between physical and psychopathological features in complex regional pain syndrome(CRPS) has been a subject of constant interest, but no data are available in adolescents. Therefore, we aimed to identify the factors associated with psychopathology in adolescents with CRPS ahead of military ***: We retrospectively reviewed all conscription examinees who had completed a Military Personality Inventory(MPI) during a period between February 2013 and December 2016. A total of 63 persons with a history of CRPS(19-years of age for all) were enrolled. Basic demographic and pain-related data were analyzed to examine their association with MPI results. The mean FGR score as well as the 8 subdomain scores were compared between those with pain duration at <15 months(n=30) vs. ≥15 months(n=33). Binary MPI results(normal-abnormal) were also compared between the two ***: In multivariate analysis, abnormal MPI was associated with pain duration, with an odds ratio(OR) at 1.05 for every 1-month increase [95% confidence interval(CI) 1.02–1.08;P=0.002]. Subjects with pain duration at ≥15 months have lower faking good response score(P<0.001 vs. those with pain duration at <15 months), and higher abnormal MPI result rate, faking bad response, inconsistency, anxiety, depression, somatization, paranoid, personality disorder cluster A, and personality disorder cluster B scores(P<0.05). Pain duration was significantly associated with the MPI ***: Pain duration is associated with psychopathology in adolescents with CRPS. Psychopathologic features increased as the disease duration increased. A comprehensive understanding of time-dependent psychopathological factors could support the planning of multimodal approaches for managing adolescent CRPS.
