| 1 | Diagnostic value of PIVKA-Ⅱ and alpha-fetoprotein in hepatitis B virus-associated hepatocellular carcinoma显示文摘AIM: To determine the cutoff values and to compare the diagnostic role of alpha-fetoprotein(AFP) and prothrombin induced by vitamin K absence-Ⅱ(PIVKA-Ⅱ) in chronic hepatitis B(CHB).METHODS: A total of 1255 patients with CHB, including 157 patients with hepatocellular carcinoma(HCC), 879 with non-cirrhotic CHB and 219 with cirrhosis without HCC, were retrospectively enrolled. The areas under the receiver operating characteristic(AUROC) curves of PIVKA-Ⅱ, AFP and their combination were calculated and compared.RESULTS: The optimal cutoff values for PIVKA-Ⅱ and AFP were 40 m AU/m L and 10 ng/m L, respectively, for the differentiation of HCC from nonmalignant CHB. The sensitivity and specificity were 73.9% and 89.7%, respectively, for PIVKA-Ⅱ and 67.5% and 90.3% for AFP, respectively. The AUROC curves of both PIVKA-Ⅱ and AFP were not significantly different(0.854 vs 0.853, P = 0.965) for the differentiation of HCC from nonmalignant CHB, whereas the AUROC of PIVKA-Ⅱ was significantly better than that of AFP in patients with cirrhosis(0.870 vs 0.812, P = 0.042). When PIVKA-Ⅱ and AFP were combined, the diagnostic power improved significantly compared to either AFP or PIVKA-Ⅱ alone for the differentiation of HCC from nonmalignant CHB(P < 0.05), especially when cirrhosis was present(P < 0.05).CONCLUSION: Serum PIVKA-Ⅱ might be a better tumor marker than AFP, and its combination with AFP may enhance the early detection of HCC in patients with CHB. | Seung In Seo Hyoung Su Kim Won Jin Kim Woon Geon Shin Doo Jin Kim Kyung Ho Kim Myoung Kuk Jang Jin Heon Lee Joo Seop Kim Hak Yang Kim Dong Joon Kim Myung Seok Lee Choong Kee Park | 2015 | World Journal of Gastroenterology2015,21,13: | 60 |
| 2 | Radiologic evaluation of nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD)is a frequent cause of chronic liver diseases,ranging from simple steatosis to nonalcoholic steatohepatitis(NASH)-related liver cirrhosis.Although liver biopsy is still the gold standard for the diagnosis of NAFLD,especially for the diagnosis of NASH,imaging methods have been increasingly accepted as noninvasive alternatives to liver biopsy.Ultrasonography is a well-established and costeffective imaging technique for the diagnosis of hepatic steatosis,especially for screening a large population at risk of NAFLD.Ultrasonography has a reasonable accuracy in detecting moderate-to-severe hepatic steatosis although it is less accurate for detecting mild hepatic steatosis,operator-dependent,and rather qualitative.Computed tomography is not appropriate for general population assessment of hepatic steatosis given its inaccuracy in detecting mild hepatic steatosis and potential radiation hazard.However,computed tomography may be effective in specific clinical situations,such as evaluation of donor candidates for hepatic transplantation.Magnetic resonance spectroscopy and magnetic resonance imaging are now regarded as the most accurate practical methods of measuring liver fat in clinical practice,especially for longitudinal followup of patients with NAFLD.Ultrasound elastography and magnetic resonance elastography are increasingly used to evaluate the degree of liver fibrosis in patients with NAFLD and to differentiate NASH from simple steatosis.This article will review current imaging methods used to evaluate hepatic steatosis,including the diagnostic accuracy,limitations,and practical applicability of each method.It will also briefly describe the potential role of elastography techniques in the evaluation of patients with NAFLD. | Seung Soo Lee Seong Ho Park | 2014 | World Journal of Gastroenterology2014,20,23: | 41 |
| 3 | Small sphincterotomy combined with endoscopic papillary large balloon dilation versus sphincterotomy显示文摘AIM:To compare small sphincterotomy combined with endoscopic papillary large balloon dilation(SES+ ELBD)and endoscopic sphincterotomy(EST)for large bile duct stones. METHODS:We compared prospectively SES+ELBD (group A,n=27)with conventional EST(group B, n=28)for the treatment of large bile duct stones(≥ 15 mm).When the stone could not be removed with a normal basket,mechanical lithotripsy was performed. We compared the rates of complete stone removal with one session and application of mechanical lithotripsy. RESULTS:No significant differences were observed in the mean largest stone size(A:20.8 mm,B:21.3 mm), bile duct diameter(A:21.4 mm,B:20.5 mm),number of stones(A:2.2,B:2.3),or procedure time(A:18 min, B:19 min)between the two groups.The rates of complete stone removal with one session was 85%in group A and 86%in group B(P=0.473).Mechanical lithotripsy was required for stone removal in nine of 27 patients(33%)in group A and nine of 28 patients (32%,P=0.527)in group B.CONCLUSION:SES+ELBD did not show significant benefits compared to conventional EST,especially for the removal of large(≥15 mm)bile duct stones. | Hyun Gun Kim Young Koog Cheon Young Deok Cho Jong Ho Moon Do Hyun Park Tae Hoon Lee Hyun Jong Choi Sang-Heum Park Joon Seong Lee Moon Sung Lee | 2009 | World Journal of Gastroenterology2009,15,34: | 34 |
| 4 | Anti-tumor activity of wogonin, an extract from Scutellaria baicalensis, through regulating different signaling pathways显示文摘Wogonin is a plant flavonoid compound extracted from Scutellaria baicalensis(Huang-Qin or Chinese skullcap) and has been studied thoroughly by many researchers till date for its anti-viral, anti-oxidant, anti-cancerous and neuro-protective properties. Numerous experiments conducted in vitro and in vivo have demonstrated wogonin's excellent tumor inhibitory properties. The anticancer mechanism of wogonin has been ascribed to modulation of various cell signaling pathways, including serine-threonine kinase Akt(also known as protein kinase B) and AMP-activated protein kinase(AMPK) pathways, p53-dependent/independent apoptosis, and inhibition of telomerase activity. Furthermore, wogonin also decreases DNA adduct formation with a carcinogenic compound 2-Aminofluorene and inhibits growth of drug resistant malignant cells and their migration and metastasis, without any side effects. Recently, newly synthesized wogonin derivatives have been developed with impressive anti-tumor activity. This review is the succinct appraisal of the pertinent articles on the mechanisms of anti-tumor properties of wogonin. We also summarize the potential of wogonin and its derivatives used alone or as an adjunct therapy for cancer treatment. Furthermore, pharmacokinetics and side effects of wogonin and its analogues have also been discussed. | Do Luong Huynh Neelesh Sharma Amit Kumar Singh Simrinder Singh Sodhi ZHANG Jiao-Jiao Raj Kumar Mongre Mrinmoy Ghosh Nameun Kim Yang Ho Park Dong Kee Jeong | 2017 | Chinese Journal of Natural Medicines2017,15,1: | 32 |

| 6 | Limited endoscopic sphincterotomy plus large balloon dilation for choledocholithiasis with periampullary diverticula显示文摘AIM: To investigate the effectiveness and safety of limited endoscopic sphincterotomy (EST) plus large balloon dilation (LBD) for removing choledocholithiasis in patients with periampullary diverticula (PAD). METHODS: A total of 139 patients with common bile duct (CBD) stones were treated with LBD (10-20 mm balloon diameter) after limited EST. Of this total, 73 patients had PAD and 66 patients did not have PAD (controls). The results of stone removal and complications were retrospectively evaluated. RESULTS: There were no significant differences between the PAD and the control groups in overall successful stone removal (94.5% vs 93.9%), stone removal in first session (69.9% vs 81.8%), mechanical lithotripsy (12.3% vs 13.6%), and complications (11.0% vs 7.6%). Clinical outcomes were also similar between the types of PAD, but the rate of stone removal in first session and the number of sessions were significantly lower and more frequent, respectively, in type B PAD (papilla located near the diverticulum) than controls [23/38 (60.5%) vs 54/66 (81.8%), P = 0.021; and 1 (1-2) vs 1 (1-3), P = 0.037, respectively] and the frequency of pancreatitis was significantly higher in type A PAD (papilla located inside or in the margin of the diverticulum) than in controls (16.1% vs 3.0%, P = 0.047). CONCLUSION: Limited EST plus LBD was an effective and safe procedure for removing choledocholithiasis in patients with PAD. However, some types of PAD should be managed with caution. | Hyung Wook Kim Dae Hwan Kang Cheol Woong Choi Jong Hwan Park Jin Ho Lee Min Dae Kim Il Doo Kim Ki Tae Yoon Mong Cho Ung Bae Jeon Suk Kim Chang Won Kim Jun Woo Lee | 2010 | World Journal of Gastroenterology2010,16,34: | 26 |
| 7 | How good is cola for dissolution of gastric phytobezoars?显示文摘AIM:To evaluate the efficacy of cola treatment for gastric phytobezoars,including diospyrobezoars.METHODS:A total of 17 patients(range:48 to 78 years) with symptomatic gastric phytobezoars treated with cola and adjuvant endoscopic therapy were reviewed.Three liters of cola lavage(10 cases) or drink(7 cases) were initially used,and then endoscopic fragmentation was done for the remnant bezoars by using a lithotripsy basket or a polypectomy snare.The overall success of dissolving a gastric phytobezoars with using three liters of cola and the clinical and endoscopic findings were compared retrospectively between four cases of complete dissolution by using only cola and 13 cases of partial dissolution with cola.RESULTS:After 3 L of cola lavage or drinking,a complete dissolution of bezoars was achieved in four patients(23.5%),while 13 cases(76.5%) were only partially dissolved.Phytobezoars(4 of 6 cases) were observed more frequently than diospyrobezoars(0 of 11) in the group that underwent complete dissolution(P = 0.006).Gender,symptom duration,size of bezoar and method of cola administration were not significantly different between the two groups.Twelve of 13 patients with residual bezoars were completely treated with a combination of cola and endoscopic fragmentation.CONCLUSION:The rate of complete dissolution with three liters of cola was 23.5%,but no case of diospyrobezoar was completely dissolved using this method.However,pretreatment with cola may be helpful and facilitate endoscopic fragmentation of gastric phytobezoars. | Beom Jae Lee Jong-Jae Park Hoon Jai Chun Ji Hoon Kim Jong Eun Yeon Yoon Tae Jeen Jae Seon Kim Kwan Soo Byun Sang Woo Lee Jae Hyun Choi Chang Duck Kim Ho Sang Ryu Young-Tae Bak | 2009 | World Journal of Gastroenterology2009,15,18: | 22 |

| 9 | Gender differences in ghrelin, nociception genes, psychological factors and quality of life in functional dyspepsia显示文摘AIM to evaluate gender differences in the aspect of ghrelin,nociception-related genes and psychological aspects and the quality of life(Qo L) in Korean functional dyspepsia(FD) patients.METHODS Total of 191 persons were prospectively enrolled between March 2013 and May 2016 in Seoul National Bundang Hospital,and classified into control and FD group based on ROME Ⅲ criteria. Questionnaire included assessment for dyspepsia symptoms,Qo L and anxiety or depression. Preproghrelin and nociception genes in the gastric mucosa and plasma acyl/des-acyl ghrelin were measured. RESULTS Lower level of plasma acyl ghrelin in FD patients compared to control was significant only in male(15.9 fmol/m L vs 10.4 fmol/m L,P = 0.017). Significantly higher m RNA expressions of nerve growth factor and transient receptor potential vanilloid receptor 1 were observed in male(P = 0.002 and P = 0.014,respectively) than in female. In contrast,female FD patients had a higher anxiety and depression score than male FD(P = 0.029),and anxiety score was correlated with epigastric pain only in female FD patients(female: Spearman rho = 0.420,P = 0.037). The impairment of overall Qo L was more prominent in female FD patients than male patients(5.4 ± 0.3 vs 6.5 ± 0.3,P = 0.020). CONCLUSION Gender differences of ghrelin and nociception-related genes in male and psychological factors in female underlie FD symptoms. More careful assessment of psychological or emotional status is required particularly for the female FD patients. | Yoon Jin Choi Young Soo Park Nayoung Kim Yong Sung Kim Sun Min Lee Dong Ho Lee Hyun Chae Jung | 2017 | World Journal of Gastroenterology2017,23,45: | 16 |

| 12 | Clinical characteristics and treatment of inflammatory bowel disease: A comparison of Eastern and Western perspectives显示文摘Inflammatory bowel disease(IBD) is a chronic, relapsing intestinal inflammatory disorder with unidentified causes. Both environmental factors and genetic aspects are believed to be crucial to the pathogenesis of IBD. The incidence and prevalence of IBD have recently been increasing throughout Asia, presumably secondary to environmental changes. This increasing trend in IBD epidemiology necessitates specific health care planning and education in Asia. To this end, we must gain a precise understanding of the distinctive clinical and therapeutic characteristics of Asian patients with IBD. The phenotypes of IBD reportedly differ considerably between Asians and Caucasians. Thus, use of the same management strategies for these different populations may not be appropriate. Moreover, investigation of the Asian-specific clinical aspects of IBD offers the possibility of identifying causative factors in the pathogenesis of IBD in this geographical area. Accordingly, this review summarizes current knowledge of the phenotypic manifestations and management practices of patients with IBD, with a special focus on a comparisonof Eastern and Western perspectives. | Soo Jung Park Won Ho Kim Jae Hee Cheon | 2014 | World Journal of Gastroenterology2014,20,33: | 15 |
| 13 | 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 |
| 14 | Characteristics of gastric cancer in peptic ulcer patients with Helicobacter pylori infection显示文摘AIM:To evaluate the incidence and clinical characteristics of gastric cancer(GC) in peptic ulcer patients with Helicobacter pylori(H.pylori) infection.METHODS:Between January 2003 and December 2013, the medical records of patients diagnosed with GC were retrospectively reviewed.Those with previous gastric ulcer(GU) and H.pylori infection were assigned to the Hp GU-GC group(n = 86) and those with previous duodenal ulcer(DU) disease and H.pylori infection were assigned to the Hp DUGC group(n = 35).The incidence rates of GC in the Hp GU-GC and Hp DU-GC groups were analyzed.Data on demographics(age, gender, peptic ulcer complications and cancer treatment), GC clinical characteristics [location, pathological diagnosis, differentiation, T stage, Lauren's classification, atrophy of surrounding mucosa and intestinal metaplasia(IM)], outcome of eradication therapy for H.pylori infection, esophagogastroduodenoscopy number and the duration until GC onset were reviewed.Univariate and multivariate analyses were performed to identify factors influencing GC development.The relative risk of GC was evaluated using a Cox proportional hazards model.RESULTS:The incidence rates of GC were 3.60%(86/2387) in the Hp GU-GC group and 1.66%(35/2098) in the Hp DU-GC group.The annual incidence was 0.41% in the Hp GU-GC group and 0.11% in the Hp DUGC group.The rates of moderate-to-severe atrophy of the surrounding mucosa and IM were higher in the Hp GU-GC group than in the Hp DU-GC group(86% vs 34.3%, respectively, and 61.6% vs 14.3%, respectively, P < 0.05).In the univariate analysis, atrophy of surrounding mucosa, IM and eradication therapy for H.pylori infection were significantly associated with the development of GC(P < 0.05).There was no significant difference in the prognosis of GC patients between the Hp GU-GC and Hp DU-GC groups(P = 0.347).The relative risk of GC development in the Hp GUGC group compared to that of the Hp DU-GC group,after correction for age and gender,was 1.71(95%CI:1.09-2.70;P=0.02).CONCLUSION:GU patients with H.pylori infection had higher GC incidence rates and relative risks.Atrophy of surrounding mucosa,IM and eradication therapy were associated with GC. | Jae Jin Hwang Dong Ho Lee Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim | 2015 | World Journal of Gastroenterology2015,21,16: | 15 |

| 16 | Clinical analysis of risk factors contributing to recurrence of pterygium after excision and graft surgery显示文摘AIM: To find the risk factors related to the reproliferation of the pterygial tissue after excision and graft surgery.METHODS: Charts of 130 eyes of 130 patients who had pterygial excision from March 2006 to April 2011 were reviewed. Preoperative pterygium morphology, surgical methods, and adjunctive treatments were statistically analyzed for their relationship with recurrence.RESULTS: During the follow-up period, recurrence was observed in 20 eyes(15.4%). None of the preoperative morphologic features were affected the rate of the recurrence. However, an age <40y [P =0.085, odds ratio(OR) 3.609, 95% confidence interval(CI) 0.838-15.540]and amniotic membrane graft instead of conjunctival autograft(P =0.002, OR 9.093, 95% CI 2.316-35.698) were statistically significant risk factors for recurrence.Multivariate analysis revealed that intraoperative mitomycin C(MMC)(P =0.072, OR 0.298, 95% CI 0.080-1.115)decreased the rate of recurrence. CONCLUSION: Younger age is a risk factor for reproliferation of pterygial tissue after excision and amniotic membrane transplantation(AMT) are less effective in preventing recurrence of pterygium after excision based on the comparison between conjunctival autograft and AMT. Intraoperative MMC application and conjunctival autograft reduce recurrence. | Sang Won Ha Joon Ho Park Im Hee Shin Hong Kyun Kim | 2015 | International Journal of Ophthalmology(English edition)2015,8,3: | 13 |

| 19 | Conventional endoscopic features are not sufficient to differentiate small, early colorectal cancer显示文摘AIM:To evaluate the depth of invasion of small,early colorectal cancers(ECCs)using conventional endoscopic features.METHODS:From January 2005 to September 2011,colonoscopy cohort showed that a total of 72 patients with small colorectal cancers with the size less than 20mm underwent colonoscopy at the Yonsei University College of Medicine,Seoul,South Korea.Among them,8 patients were excluded due to incomplete medical records.Finally,a total of 64 ECCs with submucosa(SM)invasion and size less than 20 mm were included.One hundred fifty-two adenomas with size less than 20 mm were included as controls.Nine endoscopic features,including seven morphological findings(i.e.,loss of lobulation,excavation,demarcated and depressed areas,stalk swelling,fullness,fold convergence,and bleeding ulcers),pit patterns,and non-lifting signs,were evalu-ated retrospectively.All endoscopic features were evaluated by two experienced endoscopists who have each performed over 1000 colonoscopies annually for more than five years without knowledge of the histology.RESULTS:Among the morphological findings,the size of deep submucosal cancers was bigger than that of superficial lesions(16.9 mm vs 12.3 mm,P<0.001).Also,demarcated depressed areas,stalk swelling,and fullness were more common in deep SM cancers than in superficial tumors(demarcated depressed areas:52.0%vs 15.7%,P<0.001;stalk swelling:100%vs4.2%,P<0.001;fullness:25.0%vs 0%,P=0.001).Among deep SM cancers,96%of polyps showed invasive pit patterns,whereas 19.4%of superficial tumors showed invasive pit patterns(P<0.001).A positive non-lifting sign was more common in deep SM cancers(85.0%vs 28.6%,P<0.001).Diagnostic accuracy of invasive morphology,invasive pit patterns,and nonlifting signs for deep SM cancers were 71%,82%,and75%,respectively.CONCLUSION:Conventional endoscopic findings were insufficient to discriminate small,deep SM cancers from superficial SM cancers by white light,standard colonoscopy. | Wan Park Bun Kim Soo Jung Park Jae Hee Cheon Tae Il Kim Won Ho Kim Sung Pil Hong | 2014 | World Journal of Gastroenterology2014,20,21: | 11 |
| 20 | The modulation of radiation-induced cell death by genistein in K562 cells:Activation of thymidine kinase 1显示文摘Ionizing radiation is one of the most effective tools in cancer therapy. In a previous study, we reported that protein tyrosine kinase (PTK) inhibitors modulate the radiation responses in the human chronic myelogenous leukemia (CML)cell line K562. The receptor tyrosine kinase inhibitor, genistein, delayed radiation-induced cell death, while non-recepter tyrosine kinase inhibitor, herbimycin A (HMA) enhances radiation-induced apoptosis. In this study, we focused on the modulation of radiation-induced cell death by genistein and performed PCR-select suppression subtractive hybridization(SSH) to understand its molecular mechanism. We identified human thymidine kinase 1 (TK1), which is cell cycle regulatory gene and confirmed expression of TK1 mRNA by Northern blot analysis. Expression of TK1 mRNA and TK 1enzymatic activity were parallel in their increase and decrease. TK1 is involved in G1-S phase transition of cell cycle progression. In cell cycle analysis, we showed that radiation induced G2 arrest in K562 cells but it was not able to sustain. However, the addition of genistein to irradiated cells sustained a prolonged G2 arrest up to 120 h. In addition,the expression of cell cycle-related proteins, cyclin A and cyclin B 1, provided the evidences of G1/S progression and G2-arrest, and their relationship with TK1 in cells treated with radiation and genistein. These results suggest that the activation of TK1 may be critical to modulate the radiation-induced cell death and cell cycle progression in irradiated K562 cells. | Min Ho JEONG Young Hee JIN Eun Young KANG Wol Soon JO Hwan Tae PARK Jae Dong LEE Yeo Jin YOO Soo Jin JEONG | 2004 | Cell Research2004,14,4: | 10 |
