| 2 | Visceral hypersensitivity and altered colonic motility after subsidence of inflammation in a rat model of colitis显示文摘AIM: Irritable bowel syndrome (IBS) is a functional bowel disorder characterized by visceral hypersensitivity and altered bowel motility. There is increasing evidence suggesting the role of inflammation in the pathogenesis of IBS, which addresses the possibility that formerly established rat model of colitis could be used as an TBS model after the inflammation subsided.METHODS: Colitis was induced by intracolonic instillation of 4 % acetic acid in male Sprague-Dawley rats. The extent of inflammation was assessed by histological examination and myeloperoxidase (MPO) activity assay. After subsidence of colitis, the rats were subjected to rectal distension and restraint stress, then the abdominal withdrawal reflex and the number of stress-induced fecal output were measured,respectively.RESULTS: At 2 days post-induction of colitis, the colon showed characteristic inflammatory changes in histology and 8-fold increase in MPO activity. At 7 days post-induction of colitis, the histological features and MPO activity returned to normal. The rats at 7 days post-induction of colitis showed hypersensitive response to rectal distension without an accompaning change in rectal compliance, and defecated more stools than control animals when under stress.CONCLUSION: These results concur largely with the characteristic features of IBS, visceral hypersensitivity and altered defecation pattern in the absence of detectable disease, suggesting that this animal model is a methodologically convenient and useful model for studying a subset of IBS. | Jun-Ho La Tae-Wan Kim Tae-Sik Sung Jeoung-Woo Kang Hyun-Ju Kim ⅠI-Suk Yang | 2003 | World Journal of Gastroenterology2003，9，12： | 57 |
| 3 | 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 |

| 5 | 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 |

| 9 | International consensus statement on robotic hepatectomy surgery in 2018显示文摘The robotic surgical system has been applied in liver surgery. However,controversies concerns exist regarding a variety of factors including the safety,feasibility, efficacy, and cost-effectiveness of robotic surgery. To promote the development of robotic hepatectomy, this study aimed to evaluate the current status of robotic hepatectomy and provide sixty experts' consensus and recommendations to promote its development. Based on the World Health Organization Handbook for Guideline Development, a Consensus Steering Group and a Consensus Development Group were established to determine the topics, prepare evidence-based documents, and generate recommendations. The GRADE Grid method and Delphi vote were used to formulate the recommendations. A total of 22 topics were prepared analyzed and widely discussed during the 4 meetings. Based on the published articles and expert panel opinion, 7 recommendations were generated by the GRADE method using an evidence-based method, which focused on the safety, feasibility, indication,techniques and cost-effectiveness of hepatectomy. Given that the current evidences were low to very low as evaluated by the GRADE method, further randomized-controlled trials are needed in the future to validate these recommendations. | Rong Liu Go Wakabayashi Hong-Jin Kim Gi-Hong Choi Anusak Yiengpruksawan Yuman Fong Jin He Ugo Boggi Roberto I Troisi Mikhail Efanov Daniel Azoulay Fabrizio Panaro Patrick Pessaux Xiao-Ying Wang Ji-Ye Zhu Shao-Geng Zhang Chuan-Dong Sun Zheng Wu Kai-Shan Tao Ke-Hu Yang Jia Fan Xiao-Ping Chen | 2019 | World Journal of Gastroenterology2019，25，12： | 23 |
| 10 | Endoscopic treatment for early gastric cancer显示文摘Gastric cancer remains one of the most common causes of cancer death.However the proportion of early gastric cancer(EGC)at diagnosis is increasing.Endoscopic treatment for EGC is actively performed worldwide in cases meeting specific criteria.Endoscopic mucosal resection can treat EGC with comparable results to surgery for selected cases.Endoscopic submucosal dissection(ESD)increases the en bloc and complete resection rates and reduces the local recurrence rate.ESD has been performed with expanded indication and is expected to be more widely used in the treatment of EGC through the technological advances in the near future.This review will describe the techniques,indications and outcomes of endoscopic treatment for EGC. | Yang Won Min Byung-Hoon Min Jun Haeng Lee Jae J.

| 11 | Assessment and management of low anterior resection syndrome after sphincter preserving surgery for rectal cancer显示文摘Many patients develop a variety of bowel dysfunction after sphincter preserving surgeries(SPS)for rectal cancer.The bowel dysfunction usually manifests in the form of low anterior resection syndrome(LARS),which has a negative impact on the patients'quality of life.This study reviewed the LARS after SPS,its mechanism,risk factors,diagnosis,prevention,and treatment based on previously published studies.Adequate history taking,physical examination of the patients,using validated questionnaires and other diagnostic tools are important for assessment of LARS severity.Treatment of LARS should be tailored to each patient.Multimodal therapy is usually needed for patients with major LARS with acceptable results.The treatment includes conservative management in the form of medical,pelvic floor rehabilitation and transanal irrigation and invasive procedures including neuromodulation.If this treatment failed,fecal diversion may be needed.In conclusion,Initial meticulous dissection with preservation of nerves and creation of a neorectal reservoir during anastomosis and proper Kegel exercise of the anal sphincter can minimize the occurrence of LARS.Pre-treatment counseling is an essential step for patients who have risk factors for developing LARS. | Ahmad Sakr Fozan Sauri Mohammed Alessa Eman Zakarnah Homoud Alawfi Radwan Torky Ho Seung Kim Seung Yoon Yang Nam Kyu Kim | 2020 | Chinese Medical Journal2020，，15： | 17 |
| 12 | The association of benign prostatic hyperplasia with lower urinary tract stones in adult men: A retrospective multicenter study显示文摘Objective:To examine the relationship between benign prostatic hyperplasia(BPH)and the presence of lower urinary tract stones.Methods:We retrospectively reviewed the records of men with lower urinary tract stones who presented to three clinical centers in Korea over a 4-year period.We divided the patients into two groups based on the location of urinary stones:Group 1(bladder calculi)and Group 2(urethral calculi).We compared the characteristics of both groups and performed univariate and multivariate analyses with a logistic regression model to investigate the relationship between BPH and lower urinary tract stones.Results:Of 221 patients,194(87.8%)had bladder calculi and 27(12.2%)had urethral calculi.The mean age of Group 1 was higher than that of Group 2(68.9612.11 years vs.55.7414.20 years,p<0.001).The mean prostate volume of Group 1 was higher than that of Group 2(44.4727.14 mL vs.24.706.41 mL,respectively,p<0.001).Multivariate logistic regression showed that age(OR Z 1.075,95%CI:1.023e1.129)and prostate volume(OR Z 1.069,95%CI:1.017e1.123)were independently associated with increased risk for bladder calculi.Upper urinary tract stones and/or hydronephrosis conferred a 3-fold risk for urethral calculi(OR Z 3.468,95%CI:1.093e10.999).Conclusion:Age and prostate volume are independent risk factors for bladder calculi.In addition,men with upper urinary tract disease are at greater risk for urethral calculi,which may migrate from the upper urinary tract rather than from the bladder. | Jae Hung Jung Jinsung Park Won Tae Kim Hong Wook Kim Hyung Joon Kim Sungwoo Hong Hee Jo Yang Hong Chung | 2018 | Asian Journal of Urology2018，5，2： | 17 |
| 13 | Peripheral corticotropin releasing hormone mediates post-inflammatory visceral hypersensitivity in rats显示文摘AIM:To investigate whether peripheral corticotropin releasing hormone (CRH), which is up-regulated in intestinal inflammation, mediates the post-inflammatory visceral hypersensitivity in a rat model of colitis. METHODS:We measured mucosal myeloperoxidase (MPO) activity as a marker of inflammation, plasma CRH level, and abdominal withdrawal reflex (AWR) to colorectal distension as a visceral nociceptive response at 2, 7 and 14 d after the induction of colitis with 4% acetic acid. RESULTS:Colonic inflammation, quantified by MPO activity, significantly increased on d 2 and subsided thereafter, which indicated a resolution of inflammation within 7 d. On the contrary, plasma CRH level and AWR score were increased on d 2, remained high on d 7, and returned to control level on d 14. Intraperitoneal injection of a CRH antagonist, astressin (30 μg/kg), significantly attenuated the post-inflammatory visceral hypersensitivity on d 7. Furthermore, intraperitoneal administration of CRH (3 and 10 μg/kg) mimicked the post-inflammatory visceral hypersensitivity in naive rats. CONCLUSION:These results suggest that increased peripheral CRH mediates the enhanced visceral nociception in rats recovered from experimental colitis. | Jun-Ho La Tae-Sik Sung Hyun-Ju Kim Tae-Wan Kim Tong Mook Kang Il-Suk Yang | 2008 | World Journal of Gastroenterology2008，14，5： | 15 |
| 14 | 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 |
| 15 | Noninvasive Parameters and hepatic fibrosis scores in children with nonalcoholic fatty liver disease显示文摘AIM:To evaluate the noninvasive parameters and hepatic fibrosis scores in obese children with nonalcoholic fatty liver disease(NAFLD).METHODS:A total of 77 children diagnosed with NAFLD via liver biopsy were included and divided into 2 subgroups according to the histopathologic staging of hepatic fibrosis:mild(stage 0-1)vs significant fibrosis(stage 2-4).Clinical and laboratory parameters were evaluated in each patient.The aspartate aminotransferase(AST)/alanine aminotransferase(ALT)ratio,AST/platelet ratio index(APRI),PGA index,Forns index,FIB-4,NAFLD fibrosis score,and pediatric NAFLD fibrosis index(PNFI)were calculated.RESULTS:No clinical or biochemical parameter exhibited a significant difference between patients with mild and significant fibrosis.Among noninvasive hepatic fibrosis scores,only APRI and FIB4 revealed a significant difference between patients with mild and significant fibrosis(APRI:0.67±0.54 vs 0.78±0.38,P=0.032 and FIB4:0.24±0.12 vs 0.31±0.21,P=0.010).The area under the receiving operating characteristic curve of FIB4 was 0.81,followed by Forns index(0.73),APRI(0.70),NAFLD fibrosis score(0.58),AST/ALT ratio(0.53),PGA score(0.45),and PNFI(0.41).CONCLUSION:APRI and FIB4 might be useful noninvasive hepatic fibrosis scores for predicting hepatic fibrosis in children with NAFLD. | Hye Ran Yang Hae Ryoung Kim Myung Jin Kim Jae Sung Ko Jeong Kee Seo | 2012 | World Journal of Gastroenterology2012，18，13： | 15 |

| 17 | Peroxisome-proliferator-activated receptors regulate redox signaling in the cardiovascular system显示文摘Peroxisome-proliferator-activated receptors(PPARs) comprise three subtypes(PPARα,δ and γ) to form a nuclear receptor superfamily.PPARs act as key transcriptional regulators of lipid metabolism,mitochondrial biogenesis,and anti-oxidant defense.While their roles in regulating lipid metabolism have been well established,the role of PPARs in regulating redox activity remains incompletely understood.Since redox activity is an integral part of oxidative metabolism,it is not surprising that changes in PPAR signaling in a specific cell or tissue will lead to alteration of redox state.The effects of PPAR signaling are directly related to PPAR expression,protein activities and PPAR interactions with their coregulators.The three subtypes of PPARs regulate cellular lipid and energy metabolism in most tissues in the body with overlapping and preferential effects on different metabolic steps depending on a specific tissue.Adding to the complexity,specific ligands of each PPAR subtype may also display different potencies and specificities of their role on regulating the redox pathways.Moreover,the intensity and extension of redoxregulation by each PPAR subtype are varied depending on different tissues and cell types.Both beneficial and adverse effects of PPAR ligands against cardiovascular disorders have been extensively studied by many groups.The purpose of the review is to summarize the effects of each PPAR on regulating redox and the underlying mechanisms,as well as to discuss the implications in the cardiovascular system. | Teayoun Kim Qinglin Yang | 2013 | World Journal of Cardiology2013，5，6： | 14 |
| 18 | Endoscopic submucosal dissection for early gastric cancer with undifferentiated-type histology:A meta-analysis显示文摘AIM: To evaluate the efficacy and safety of endoscopicsubmucosal dissection(ESD) for early gastric cancer(EGC) with undifferentiated-type histology.METHODS: A systematic literature review was conducted using the core databases. Complete resection,curative resection, en bloc resection, recurrence and adverse event rate were extracted and analyzed. A random effect model was applied. The methodological quality of the enrolled studies was assessed using the Newcastle-Ottawa Scale. Publication bias was evaluated using a funnel plot, the trim and fill method, Egger's test,and a rank correlation test.RESULTS: Fourteen retrospective studies between2009 and 2014 were identified(972 EGC lesions with undifferentiated-type histology). The total en bloc and complete resection rates were estimated as92.1%(95%CI: 87.4%-95.2%) and 77.5%(95%CI:69.3%-84%), respectively. The total curative resection rate was 61.4%(95%CI: 44.5%-75.9%). The overall recurrence rate was 7.6%(95%CI: 3.4%-16%).Limited to histologically diagnosed expanded-criteria lesions, the en bloc and complete resection rates were91.2% and 85.6%, respectively. The curative resection rate was 79.8%.CONCLUSION: In this analysis, ESD is a technically feasible treatment modality for EGC with undifferentiatedtype histology. Long-term studies are needed to confirm these therapeutic outcomes. | Chang Seok Bang Gwang Ho Baik In Soo Shin Jing Bong Kim Ki Tae Suk Jai Hoon Yoon Yeon Soo Kim Dong Joon Kim Woon Geon Shin Kyung Ho Kim Hak Yang Kim Hyun Lim Ho Seok Kang Jong Hyeok Kim Jin Bae Kim Sung Won Jung Sea Hyub Kae Hyun Joo Jang Min Ho Choi | 2015 | World Journal of Gastroenterology2015，21，19： | 14 |
| 19 | When water meets iron at Earth's core-mantle boundary显示文摘Hydrous minerals in subducted crust can transport large amounts of water into Earth's deep mantle. Our laboratory experiments revealed the surprising pressure-induced chemistry that, when water meets iron at the core-mantle boundary, they react to form an interlayer with an extremely oxygen-rich form of iron, iron dioxide, together with iron hydride. Hydrogen in the layer will escape upon further heating and rise to the crust, sustaining the water cycle. With water supplied by the subducting slabs meeting the nearly inexhaustible iron source in the core, an oxygen-rich layer would cumulate and thicken, leading to major global consequences in our planet. The seismic signature of the D″ layer may echo the chemical complexity of this layer. Over the course of geological time, the enormous oxygen reservoir accumulating between the mantle and core may have eventually reached a critical eruption point. Very large-scale oxygen eruptions could possibly cause major activities in the mantle convection and leave evidence such as the rifting of supercontinents and the Great Oxidation Event. | Ho-Kwang Mao Qingyang Hu Liuxiang Yang Jin Liu Duck Young Kim Yue Meng Li Zhang Vitali B.Prakapenka Wenge Yang Wendy L.Mao | 2017 | National Science Review2017，4，6： | 14 |
