| 1 | Effect of pronase as mucolytic agent on imaging quality of magnifying endoscopy显示文摘AIM:To investigate the efficacy of premedication with pronase,a proteolytic enzyme,in improving imagequality during magnifying endoscopy.METHODS:The study was of a blinded,randomized,prospective design.Patients were assigned to groups administered oral premedication of either pronase and simethicone(Group A)or simethicone alone(Group B).First,the gastric mucosal visibility grade(1-4)was determined during conventional endoscopy,and then a magnifying endoscopic examination was conducted.The quality of images obtained by magnifying endoscopy at the stomach and the esophagus was scored from1 to 3,with a lower score indicating better visibility.The endoscopist used water flushes as needed to obtain satisfactory magnifying endoscopic views.The main study outcomes were the visibility scores during magnifying endoscopy and the number of water flushes.RESULTS:A total of 144 patients were enrolled,and data from 143 patients(M:F=90:53,mean age 57.5 years)were analyzed.The visibility score was significantly higher in the stomach following premedication with pronase(73%with a score of 1 in Group A vs 49%in Group B,P<0.05),but there was no difference in the esophagus visibility scores(67%with a score of 1in Group A vs 58%in Group B).Fewer water flushes[mean 0.7±0.9 times(range:0-3 times)in Group A vs 1.9±1.5 times(range:0-6 times)in Group B,P<0.05]in the pronase premedication group did not affect the endoscopic procedure times[mean 766 s(range:647-866 s)for Group A vs 760 s(range:678-854 s)for Group B,P=0.88].The total gastric mucosal visibility score was also lower in Group A(4.9±1.5 vs 8.3±1.8in Group B,P<0.01).CONCLUSION:The addition of pronase to simethicone premedication resulted in clearer images during magnifying endoscopy and reduced the need for water flushes. | Gwang Ha Kim Yu Kyung Cho Jae Myung Cha Sun-Young Lee Il-Kwun Chung | 2015 | World Journal of Gastroenterology2015，21，8： | 21 |
| 2 | Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite. | Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon | 2009 | World Journal of Gastroenterology2009，15，1： | 15 |
| 3 | Long-term follow up of endoscopic resection for type 3 gastric NET显示文摘AIM:To clarify the short and long-term results and to prove the usefulness of endoscopic resection in type 3gastric neuroendocrine tumors(NETs).METHODS:Of the 119 type 3 gastric NETs diagnosed from January 1996 to September 2011,50 patients treated with endoscopic resection were enrolled in this study.For endoscopic resection,endoscopic mucosal resection(EMR)or endoscopic submucosal dissection(ESD)was used.Therapeutic efficacy,complications,and follow-up results were evaluated retrospectively.RESULTS:EMR was performed in 41 cases and ESD in 9 cases.Pathologically complete resection was performed in 40 cases(80.0%)and incomplete resection specimens were observed in 10 cases(7 vs 3 patients in the EMR vs ESD group,P=0.249).Upon analysis of the incomplete resection group,lateral or vertical margin invasion was found in six cases(14.6%)in the EMR group and in one case in the ESD group(11.1%).Lymphovascular invasions were observed in two cases(22.2%)in the ESD group and in one case(2.4%)in the EMR group(P=0.080).During the follow-up period(43.73;13-60 mo),there was no evidence of tumor recurrence in either the pathologically complete resection group or the incomplete resection group.No recurrence was reported during follow-up.In addition,no mortality was reported in either the complete resection group or the incomplete resection group for the duration of the follow-up period.CONCLUSION:Less than 2 cm sized confined submucosal layer type 3 gastric NET with no evidence of lymphovascular invasion,endoscopic treatment could be considered at initial treatment. | Yong Hwan Kwon Seong Woo Jeon Gwang Ha Kim Jin Il Kim Il-Kwun Chung Sam Ryong Jee Heung Up Kim Geom Seog Seo Gwang Ho Baik Kee Don Choi Jeong Seop Moon | 2013 | World Journal of Gastroenterology2013，19，46： | 14 |
| 4 | Efforts to increase image quality during endoscopy:The role of pronase显示文摘Clear visualization of the gastrointestinal mucosal surface is essential for thorough endoscopy. An unobstructed assessment can reduce the need for additional timeconsuming manipulations such as frequent washing and suction,which tend to prolong total procedure time. However,mucus,foam,and bubbles often hinder clear visibility during endoscopy. Premedication with pronase,a compound of mixed proteolytic enzymes,has been studied in order to improve mucosal visibility during endoscopy. Although its effects differ according to the location in the stomach,premedication with pronase 10 to 20 min before endoscopy significantly improves mucosal visibility without affecting the accuracy of Helicobacter pylori identification. The effects of pronase as premedication also extend to chromoendoscopy,narrow-band imaging,magnifying endoscopy,and endoscopic ultrasonography. In addition,endoscopic flushing with pronase during endoscopy may improve the quantity and the quality of a biopsy to some degree. Although improved mucosal visibility does not necessarily improve clinical outcomes,premedication with pronase may be helpful for increasing the detection rate of early cancers. | Gwang Ha Kim Yu Kyung Cho Jae Myung Cha Sun-Young Lee Il-Kwun Chung | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，5： | 13 |
| 5 | Ethanolic extract of dandelion(Taraxacum mongolicum) induces estrogenic activity in MCF-7 cells and immature rats显示文摘Plants of the genus Taraxacum, commonly known as dandelions, are used to treat breast cancer in traditional folk medicine. However, their use has mainly been based on empirical findings without sufficient scientific evidence. Therefore, we hypothesized that dandelions would behave as a Selective estrogen receptor modulator(SERM) and be effective as hormone replacement therapy(HRT) in the postmenopausal women. In the present study, in vitro assay systems, including cell proliferation assay, reporter gene assay, and RT-PCR to evaluate the m RNA expression of estrogen-related genes(p S2 and progesterone receptor, PR), were performed in human breast cancer cells. Dandelion ethanol extract(DEE) significantly increased cell proliferation and estrogen response element(ERE)-driven luciferase activity. DEE significantly induced the expression of estrogen related genes such as p S2 and PR, which was inhibited by tamoxifen at 1 μmol·L-1. These results indicated that DEE could induce estrogenic activities mediated by a classical estrogen receptor pathway. In addition, immature rat uterotrophic assay was carried out to identify estrogenic activity of DEE in vivo. The lowest concentration of DEE slightly increased the uterine wet weight, but there was no significant effect with the highest concentration of DEE. The results demonstrate the potential estrogenic activities of DEE, providing scientific evidence supporting their use in traditional medicine. | Seung Min Oh Ha Ryong Kim Yong Joo Park Yong Hwa Lee Kyu Hyuck Chung | 2015 | Chinese Journal of Natural Medicines2015，13，11： | 11 |

| 8 | A case of long survival in poorly differentiated small cell carcinoma of the pancreas显示文摘Small cell carcinoma (SCC) of the pancreas is rare. It has similar histological features to pulmonary small cell carcinoma and is equally aggressive. Most patients with SCC in the pancreas reported in case studies died within 1 year after diagnosis. We present a case of unusually long-term survival after surgery and combined chemotherapy for SCC of the pancreas. A 62-year-old woman presented with epigastric pain and jaundice. Computed tomography revealed dilated common bile duct caused by external compression of the mass in the pancreatic head. Exploratory laparotomy and pancreaticoduodenectomy (PPPD) was performed with histopathological analysis confirming a primary small cell carcinoma of the pancreas. After an uneventful postoperative recovery, the patient was treated with 6 cycles of combined chemotherapy consisting of cisplantin and ectoposide. During the follow-up, there was no evidence of recurrence and the patient has remained in a good health condition for 36 mo since the diagnosis. | Min Sung Chung Tae Kyung Ha Kyeung Geun Lee Seung Sam Paik | 2008 | World Journal of Gastroenterology2008，14，31： | 4 |

| 11 | Dietary fat-associated osteoarthritic chondrocytes gain resistance to lipotoxicity through PKCK2/STAMP2/FSP27显示文摘Free fatty acids(FFAs), which are elevated with metabolic syndrome, are considered the principal offender exerting lipotoxicity. Few previous studies have reported a causal relationship between FFAs and osteoarthritis pathogenesis. However, the molecular mechanism by which FFAs exert lipotoxicity and induce osteoarthritis remains largely unknown. We here observed that oleate at the usual clinical range does not exert lipotoxicity while oleate at high pathological ranges exerted lipotoxicity through apoptosis in articular chondrocytes. By investigating the differential effect of oleate at toxic and nontoxic concentrations, we revealed that lipid droplet(LD) accumulation confers articular chondrocytes, the resistance to lipotoxicity. Using high fat diet-induced osteoarthritis models and articular chondrocytes treated with oleate alone or oleate plus palmitate, we demonstrated that articular chondrocytes gain resistance to lipotoxicity through protein kinase casein kinase 2(PKCK2)—six-transmembrane protein of prostate 2(STAMP2)—and fat-specific protein 27(FSP27)-mediated LD accumulation. We further observed that the exertion of FFAs-induced lipotoxicity was correlated with the increased concentration of cellular FFAs freed from LDs, whether FFAs are saturated or not. In conclusion, PKCK2/STAMP2/FSP27-mediated sequestration of FFAs in LD rescues osteoarthritic chondrocytes. PKCK2/STAMP2/FSP27 should be considered for interventions against metabolic OA. | Sung Won Lee Jee Hyun Rho Sang Yeob Lee Won Tae Chung Yoo Jin Oh Jung Ha Kim Seung Hee Yoo Woo Young Kwon Ju Yong Bae Su Young Seo Hokeun Sun Hye Young Kim Young Hyun Yoo | 2018 | Bone Research2018，6，3： | 3 |

| 13 | Extracts from Paeonia lactiflora Pallas, Rehmannia Glutinosa var. Purpurea Makino, Perilla Frutescens var. Acuta Kudo may increase the endometrial receptivity through expression of leukemia inhibitory factor and adhesion molecules显示文摘OBJECTIVE: To find out the combination of the extracts from Paeonia lactiflora Pallas(PL), Rehmannia Glutinosa var. Purpurea Makino(RG), Perilla Frutescens var. Acuta Kudo(PF) to increase endometrial receptivity.METHODS: Herbal medicines were extracted with boiling water and polysaccharides were removed.We examined the effect of PL, RG, and PF(PRP), a most effective herbal formula deduced from constitutive ingredient herbs of Antai Yin which is composed of PRP, on the leukemia inhibitory factor(LIF) expression and endometrial receptivity.RESULTS: The combination of the extracts from PRP induced the LIF expression in Ishikawa cells and increased the adhesion between Ishikawa and JAr cells. In addition, PRP-induced attachment of JAr cells onto Ishikawa cells and expression of adhesion molecules, ITGAV, ITGB5, CD44 s, and Lselectin, are significantly reduced by knock-down of LIF expression.CONCLUSION: Induced by the combination of the PRP extracts, the adhesion between trophoblast and endometrial cells are mediated by expression of LIF and adhesion molecules. Thus, we suggest the combination of the PRP extracts may be a novel therapy for enhancing embryo implantation rate. | Eun-Yeong Kim Tae-Wook Chung Hee-Jung Choi Yeon-Seop Jung Syng-Ook Lee Jun-Yong Choi Hyung Sik Kim Sooseong You Myeong Soo Lee Ki-Tae Ha | 2019 | Journal of Traditional Chinese Medicine2019，39，1： | 3 |
| 14 | Selective catalytic NO_x reduction on Antimony promoted V_2O_5-Sb/TiO_2 catalyst显示文摘Quantum chemical calculation was carried out to choose a promoter which can reduce the poisoning of V2O5/TiO2 catalysts by SO2. Several atoms were chosen as candidates and new catalysts were synthesized by impregnation method. The NOx conversion rate was measured at temperatures between 100 and 400 ℃ and poisoning effect was investigated. The most promising candidate promoter, Se, was excluded because of its high vapor pressure. On the other hand, Sb shows best promoting properties. Sb promoted catalyst reaches the maximum NOx conversion rate at 250 ℃. It also shows considerably enhanced resistance to poisoning of V2O5/TiO2 catalysts by SO2. | HA Heon Phil CHUNG Soon Hyo OH Young Joo | 2006 | Rare Metals2006，25，z2： | 3 |
