1Prevalence 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 2009World Journal of Gastroenterology2009,15,1:15
2Clinical significance and risk factors of postembolization fever in patients with hepatocellular carcinoma显示文摘AIM:To investigate tumor response and survival in patients with postembolization fever(PEF) and to determine the risk factors for PEF.METHODS:Four hundred forty-three hepatocellular carcinoma(HCC) patients who underwent the first session of transcatheter arterial chemoembolization(TACE) between January 2005 and December 2009 were analyzed retrospectively.PEF was defined as a body temperature greater than 38.0 ℃ that developed within 3 d of TACE without evidence of infection.The tumor progression-free interval was defined as the interval from the first TACE to the second TACE based on mRECIST criteria.Clinical staging was based on the American Joint Committee on Cancer tumor,node,metastases(TNM) classification of malignant tumors.All patients were admitted before their 1 st TACE treatment,and blood samples were obtained from all patients before and after treatment.Clinicoradiological variables and host-related variables were compared between two groups:patients with PEF vs patients without PEF.Additionally,variables related to 20-mo mortality and tumor progression-free survival were analyzed.RESULTS:The study population comprised 370(85.4%) men and 73(14.6%) women with a mean age of 62.29 ± 10.35 years.A total of 1836 TACE sessions were conducted in 443 patients,and each patient received between 1 and 27(mean:4.14 ± 3.57) TACE sessions.The mean follow-up duration was 22.23 ± 19.6 mo(range:0-81 mo).PEF developed in 117 patients(26.41%) at the time of the first TACE session.PEF was not associated with 20-mo survival(P = 0.524) or computed tomography(CT) response(P = 0.413) in a univariate analysis.A univariate analysis further indicated that diffuse-type HCC(P = 0.021),large tumor size(≥ 5 cm)(P = 0.046),lipiodol dose(≥ 7 mL,P = 0.001),poor blood glucose control(P = 0.034),alanine aminotransferase(ALT) value after TACE(P = 0.004) and C-reactive protein(CRP) value after TACE(P = 0.036) served as possible risk factors correlated with PEF.The ALT value after TACE(P = 0.021) and lipiodol dose over 7 mL(P = 0.011) were independent risk factors for PEF in the multivariate analysis.For the 20-mo survival,poor blood sugar control(P < 0.001),portal vein thrombosis(P = 0.001),favorable CT response after TACE(P < 0.001),initial aspartate aminotransferase(P = 0.02),initial CRP(P = 0.042),tumor size(P < 0.001),TNM stage(P < 0.001) and lipiodol dose(P < 0.001) were possible risk factors in the univariate analysis.Tumor size(P = 0.03),poor blood sugar control(P = 0.043),and portal vein thrombosis(P = 0.031) were significant predictors of survival in the multivariate analysis.Furthermore,the tumor progression-free interval was closely associated with CRP > 1 mg/dL(P = 0.003),tumor size > 5 cm(P < 0.001),tumor type(poorly defined)(P < 0.001),and lipiodol dose(> 7 mL,P < 0.001).CONCLUSION:PEF has no impact on survival at 20 mo or radiologic response.However,the ALT level after TACE and the lipiodol dose represent significant risk factors for PEF.Chung Hwan Jun Ho Seok Ki Hoon Ki Lee Kang Jin Park Seon Young Park Sung Bum Cho Chang Hwan Park Young Eun Joo Hyun Soo Kim Sung Kyu Choi Jong Sun Rew 2013World Journal of Gastroenterology2013,19,2:7
3Testicular sperm extraction and intracytoplasmic sperm injection in non obstructive azoospermia显示文摘Objective To report the experience in sperm extraction from testicular biopsies (TESE) performed from March 1996 to July 1998 in men with non obstructive azoospermia (NOA) Methods Comparisons of age, volume of both testes, serum FSH and testosterone in men, and histology of testicular samples in the first cycles between cycles with spermatozoa found and those without spermatozoa found were performed Comparisons of fertilization, cleavage and pregnancy rates between cycles with spermatozoa injected and those with spermatids injected were performed Results Spermatozoa were found in only 12 out of 26 first TESE cycles (46 2%) and other cycles had spermatids (round cells) only Age of men, history of mumps orchitis/oligozoospermia, volume of both testes and serum FSH/testosterone levels in men were not significantly different between cycles with and without spermatozoa The fertilization rate was significantly higher in cycles with spermatozoa injected than those with round cell injections (63 3% vs 23 2%, P <0 0001, Chi squared test) The pregnancy rate was 14 3% per cycle when spermatozoa were injected Conclusions TESE followed by Intracytoplasmic sperm injection (ICSI) is an effective treatment in patients with NOA Less than half of the patients undergoing TESE had spermatozoa recovered Age of men, volume of both testes and serum FSH/ testosterone levels in men were not useful in predicting successful recovery Compared to using ejaculated and epididymal spermatozoa, fertilization and pregnancy rates were achieved when testicular spermatozoa were used forNg Hung Yu Ernest, Lau Yee Lan, Yeung Shu Biu, So Wai Ki, Tam Po Chor and Ho Pak Chung 2000Chinese Medical Journal2000,,3:7
4Molecular mechanisms of chemopreventive phytochemicals against gastroenterological cancer development显示文摘Cancer is one of the leading causes of death worldwide.Commonly used cancer treatments,including chemotherapy and radiation therapy,often have side effects and a complete cure is sometimes impossible.Therefore,prevention,suppression,and/or delaying the onset of the disease are important.The onset of gastroenterological cancers is closely associated with an individual's lifestyle.Thus,changing lifestyle,specifically the consumption of fruits and vegetables,can help to protect against the development of gastroenterological cancers.In particular,naturally occurring bioactive compounds,including curcumin,resveratrol,isothiocyanates,(-)-epigallocatechin gallate and sulforaphane,are regarded as promising chemopreventive agents.Hence,regular consumption of these natural bioactive compounds found in foods can contribute to prevention,suppression,and/or delay of gastroenterological cancer development.In this review,we will summarize natural phytochemicals possessing potential antioxidant and/or anti-inflammatory and anti-carcinogenic activities,which are exerted by regulating or targeting specific molecules against gastroenterological cancers,including esophageal,gastric and colon cancers.Min-Yu Chung Tae Gyu Lim Ki Won Lee 2013World Journal of Gastroenterology2013,19,7:7
5Amomum villosum induces longitudinal bone growth in adolescent female rats显示文摘OBJECTIVE:This study was conducted to evaluate the effect of Amomum villosum on longitudinal bone growth.METHODS:Adolescent female Sprague-Dawley rats were divided into 3 groups and treated for 4 days:control(distilled water,p.o.),recombinant human growth hormone(rhGH;100 μg/kg,s.c.),and A.villosum(500 mg/kg,p.o.) groups.On day 3,tetracycline(20 g/kg,i.p.) was injected for growth plate identification.On days 2,3 and 4,5-bromo-2'-deoxyuridine(BrdU)(50 mg/kg,i.p.) was injected to label proliferating cells.On day 5,tibias were dissected and fixed in 4% paraformaldehyde,dehydrated,and sectioned for immunohistochemistry and histomorphometry.RESULTS:The rate of bone growth in the A.villosum and rhGH groups increased to(410 ± 44) and(389 ± 46) μm/day(P<0.01),respectively,as compared with the control(330.7 ± 34.7) μm/day.The thickness of the growth plates also increased to(591 ± 37) and(598 ± 32) μm,respectively,as compared with the control(524± 89) μm(P<0.001).The number of BrdU-positive cells in the chondrocytes of the A.villosum and rhGH groups was also significantly higher(126±24) and(143±18) cells/mm 2,respectively) than in the control(109 ± 25) mm 2(P<0.05).Insulin-like growth factor-1 and bone morphogenetic protein-2 in the A.villosum and rhGH groups were highly expressed in the growth plate as compared with the control samples,indicating increased bone formation.CONCLUSIONS:A.villosum could be used to treat growth retardation during adolescence.Sun Haeng Lee Ji Young Kim Hocheol Kim Seul Ki Park Cho Young Kim Sun Yong Chung Gyu Tae Chang 2012Journal of Traditional Chinese Medicine2012,32,3:6
6Effects of drought stress on root morphology and spatial distribution of soybean and adzuki bean显示文摘Due to global climate change,Korea is facing severe droughts that affect the planting and early vegetative periods of upland crops.Soybean and adzuki bean are important legume crops in Korea,so it is critical to understand their adaptations to water stress.This study investigated the changes in root morphological properties in soybean and adzuki bean and quantified the findings using fractal analysis.The experiment was performed at the National Institute of Crop Science in Miryang,Korea.Soybeans and adzuki beans were planted in test boxes and grown for 30 days.The boxes were filled with bed soil with various soil moisture treatments.Root images were obtained and scanned every two days,and the root properties were characterized by root length,depth and surface area,number of roots,and fractal parameters(fractal dimension and lacunarity).Root depth,length and surface area and the number of roots increased in both crops as the soil moisture content increased.The fractal dimension and lacunarity values increased as the soil moisture content increased.These results indicated that the greater the soil moisture,the more heterogeneous the root structure.Correlation analysis of the morphological properties and fractal parameters indicated that soybean and adzuki bean had different root structure developments.Both soybean and adzuki bean were sensitive to the amount of soil moisture in the early vegetative stage.Soybean required a soil moisture content greater than 70%of the field capacity to develop a full root structure,while adzuki bean required 100%of the field capacity.These results would be useful in understanding the responses of soybean and adzuki bean to water stress and managing irrigation during cultivation.Hyen Chung CHUN Sanghun LEE Young Dae CHOI Dong Hyeok GONG Ki Youl JUNG 2021Journal of Integrative Agriculture2021,20,10:5
7Antioxidative phytoceuticals to ameliorate pancreatitis in animal models: An answer from nature显示文摘Despite enthusiastic efforts directed at elucidating critical underlying mechanisms towards the identification of novel therapeutic targets for severe acute pancreatitis(SAP), the disease remains without a specific therapy to be executed within the first hours to days after onset of symptoms. Although earlier management for SAP should aim to either treat organ failure or reduce infectious complications, the current standard of care for the general management of AP in the first hours to days after onset of symptoms include intravenous fluid replacement, nutritional changes, and the use of analgesics with a close monitoring of vital signs. Furthermore, repeated evaluation of severity is very important, as the condition is particularly unstable in the early stages. In cases where biliary pancreatitis is accompanied by acute cholangitis or in cases where biliary stasis is suspected,an early endoscopic retrograde cholangiopancreatography is recommended.However,practice guidelines regarding the treatment of pancreatitis are suboptimal.In chronic pancreatitis,conservative management strategies include lifestyle modifications and dietary changes followed by analgesics and pancreatic enzyme supplementation.Recently,attention has been focused on phytoceuticals or antioxidants as agents that could surpass the limitations associated with currently available therapies.Because oxidative stress has been shown to play an important role in the pathogenesis of pancreatitis,antioxidants alone or combined with conventional therapy may improve oxidativestress-induced organ damage.Interest in phytoceuticals stems from their potential use as simple,accurate tools for pancreatitis prognostication that could replace older and more tedious methods.Therefore,the use of antioxidative nutrition or phytoceuticals may represent a new direction for clinical research in pancreatitis.In this review article,recent advances in the understanding of the pathogenesis of pancreatitis are discussed and the paradigm shift underway to develop phytoceuticals and antioxidants to treat it is introduced.Despite the promise of studies evaluating the effects of antioxidants/phytoceuticals in pancreatitis,translation to the clinic has thus far been disappointing.However,it is expected that continued research will provide solid evidence to justify the use of antioxidative phytoceuticals in the treatment of pancreatitis.Jong-Min Park Sooyeon Lee Mi Kyung Chung Sung-Hun Kwon Eun-Hee Kim Kwang Hyun Ko Chang Il Kwon Ki Baik Hahm 2014World Journal of Gastroenterology2014,20,44:5

9Comparison of CT and MRI for presurgical characterization of paraaortic lymph nodes in patients with pancreatico-biliary carcinoma显示文摘AIM:To determine the accuracy of computed tomography (CT) and magnetic resonance (MR) for presurgical characterization of paraaortic lymph nodes in patients with pancreatico-biliary carcinoma. METHODS:Two radiologists independently evaluated CT and MR imaging of 31 patients who had undergone lymphadenectomy (9 metastatic and 22 non-metastatic paraaortic nodes). Receiver operating characteristic (ROC) curve analysis was performed using a five point scale to compare CT with MRI. To re-define the morphologic features of metastatic nodes, we evaluated CT scans from 70 patients with 23 metastatic paraaortic nodes and 47 non-metastatic ones. The short axis diameter, ratio of the short to long axis, shape, and presence of necrosis were compared between metastatic and non-metastatic nodes by independent samples t-test and Fisher's exact test. P < 0.05 was considered statistically significant. RESULTS:The mean area under the ROC curve for CT (0.732 and 0.646, respectively) was slightly higher than that for MRI (0.725 and 0.598, respectively) without statistical significance (P = 0.940 and 0.716,respectively). The short axis diameter of the metastatic lymph nodes (mean = 9.2 mm) was significantly larger than that of non-metastatic ones (mean = 5.17 mm, P < 0.05). Metastatic nodes had more irregular margins (44.4%) and central necrosis (22.2%) than non-metastatic ones (9% and 0%, respectively), with statistical significance (P < 0.05). CONCLUSION:The accuracy of CT scan for the characterization of paraaortic nodes is not different from that of MRI. A short axis-diameter (> 5.3 mm), irregular margin, and presence of central necrosis are the suggestive morphologic features of metastatic paraaortic nodes.Young Chul Kim Mi-Suk Park Seung-Whan Cha Yong Eun Chung Joon Suk Lim Myeong-Jin Kim Ki Whang Kim Kyung Sik Kim 2008World Journal of Gastroenterology2008,14,14:4

11Comparison of a novel bedside portable endoscopy device with nasogastric aspiration for identifying upper gastrointestinal bleeding显示文摘AIM: To compare outcomes using the novel portable endoscopy with that of nasogastric(NG) aspiration in patients with gastrointestinal bleeding.METHODS: Patients who underwent NG aspiration for the evaluation of upper gastrointestinal(UGI) bleeding were eligible for the study. After NG aspiration, we performed the portable endoscopy to identify bleeding evidence in the UGI tract. Then, all patients underwent conventional esophagogastroduodenoscopy as the gold-standard test. The sensitivity, specificity, and accuracy of the portable endoscopy for confirming UGI bleeding were compared with those of NG aspiration.RESULTS: In total, 129 patients who had GI bleedingsigns or symptoms were included in the study(age 64.46 ± 13.79, 91 males). The UGI tract(esophagus, stomach, and duodenum) was the most common site of bleeding(81, 62.8%) and the cause of bleeding was not identified in 12 patients(9.3%). Specificity for identifying UGI bleeding was higher with the portable endoscopy than NG aspiration(85.4% vs 68.8%, P = 0.008) while accuracy was comparable. The accuracy of the portable endoscopy was significantly higher than that of NG in the subgroup analysis of patients with esophageal bleeding(88.2% vs 75%, P = 0.004). Food material could be detected more readily by the portable endoscopy than NG tube aspiration(20.9% vs 9.3%, P = 0.014). No serious adverse effect was observed during the portable endoscopy.CONCLUSION: The portable endoscopy was not superior to NG aspiration for confirming UGI bleeding site. However, this novel portable endoscopy device might provide a benefit over NG aspiration in patients with esophageal bleeding.Jong Hwan Choi Jae Hyuk Choi Yoo Jin Lee Hyung Ki Lee Wang Yong Choi Eun Soo Kim Kyung Sik Park Kwang Bum Cho Byoung Kuk Jang Woo Jin Chung Jae Seok Hwang 2014World Journal of Gastroenterology2014,20,25:3
