| 1 | Common bile duct stones on multidetector computed tomography:Attenuation patterns and detectability显示文摘AIM:To investigate the attenuation patterns and detectability of common bile duct(CBD) stones by multidetector computed tomography(MDCT).METHODS:Between March 2010 and February 2012,191 patients with suspicion of CBD stones undergoing both MDCT and endoscopic retrograde cholangiopancreatography(ERCP) were enrolled and reviewed retrospectively.The attenuation patterns of CBD stones on MDCT were classified as heavily calcified,radiopaque,less radiopaque,or undetectable.The association between the attenuation patterns of CBD stones on MDCT and stone type consisting of pure cholesterol,mixed cholesterol,brown pigment,and black pigment and the factors related to the detectability of CBD stones by MDCT were evaluated.RESULTS:MDCT showed CBD stones in 111 of 130 patients in whom the CBD stones were demonstrated by ERCP with 85.4% sensitivity.The attenuation patterns of CBD stones on MDCT were heavily calcified 34(26%),radiopaque 31(24%),less radiopaque 46(35%),and undetectable 19(15%).The radiopacity of CBD stones differed significantly according to stone type(P < 0.001).From the receiver operating characteristic curve,stone size was useful for the determination of CBD stone by MDCT(area under curve 0.779,P < 0.001) and appropriate cut-off stone size on MDCT was 5 mm.The factors related to detectability of CBD stones on MDCT were age,stone type,and stone size on multivariate analysis(P < 0.05).CONCLUSION:The radiopacity of CBD stones on MDCT differed according to stone type.Stone type and stone size were related to the detectability by MDCT,and appropriate cut-off stone size was 5 mm. | Chang Whan Kim Jae Hyuck Chang Yeon Soo Lim Tae Ho Kim In Seok Lee Sok Won Han | 2013 | World Journal of Gastroenterology2013，19，11： | 24 |
| 2 | Overexpression of the M2 isoform of pyruvate kinase is an adverse prognostic factor for signet ring cell gastric cancer显示文摘AIM:To investigate M2 isoform of pyruvate kinase(PKM2) expression in gastric cancers and evaluate its potential as a prognostic biomarker and an anticancer target.METHODS:All tissue samples were derived from gastric cancer patients underwent curative gastrectomy as a primary treatment.Clinical and pathological information were obtained from the medical records.Gene expression microarray data from 60 cancer and 19 noncancer gastric tissues were analyzed to evaluate the expression level of PKM2 mRNA.Tissue microarrays were constructed from 368 gastric cancer patients.Immunohistochemistry was used to measure PKM2 expression and PKM2 positivity of cancer was determined by proportion of PKM2-positive tumor cells and staining intensity.Association between PKM2 expression and the clinicopathological factors was evaluated and the correlation between PKM2 and cancer prognosis was evaluated.RESULTS:PKM2 mRNA levels were increased more than 2-fold in primary gastric cancers compared to adjacent normal tissues from the same patients(log transformed expression level:7.6 ± 0.65 vs 6.3 ± 0.51,P < 0.001).Moreover,differentiated type cancers had significantly higher PKM2 mRNA compared to undifferentiated type cancers(log transformed expression level:7.8 ± 0.70 vs 6.7 ± 0.71,P < 0.001).PKM2 protein was mainly localized in the cytoplasm of primary cancer cells and detected in 144 of 368(39.1%) human gastric cancer cases.PKM2 expression was not related with stage(P = 0.811),but strongly correlated with gastric cancer differentiation(P < 0.001).Differentiated type cancers expressed more PKM2 protein than did the undifferentiated ones.Well differentiated adenocarcinoma showed 63.6% PKM2-positive cells;in contrast,signet-ring cell cancers showed only 17.7% PKM2-positive cells.Importantly,PKM2 expression was correlated with shorter overall survival(P < 0.05) independent of stage only in signet-ring cell cancers.CONCLUSION:PKM2 expression might be an adverse prognostic factor for signet-ring cell carcinomas.Its function and potential as a prognostic marker should be further verified in gastric cancer. | Jae Yun Lim Sun Och Yoon So Young Seol Soon Won Hong Jong Won Kim Seung Ho Choi Jae Yong Cho | 2012 | World Journal of Gastroenterology2012，18，30： | 19 |

| 4 | 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 |
| 5 | Overview of multiplex immunohistochemistry/immunofluorescence techniques in the era of cancer immunotherapy显示文摘Conventional immunohistochemistry(IHC)is a widely used diagnostic technique in tissue pathology.However,this technique is associated with a number of limitations,including high inter-observer variability and the capacity to label only one marker per tissue section.This review details various highly multiplexed techniques that have emerged to circumvent these constraints,allowing simultaneous detection of multiple markers on a single tissue section and the comprehensive study of cell composition,cellular functional and cell-cell interactions.Among these techniques,multiplex Immunohistochemistry/Immunofluorescence(mIHC/IF)has emerged to be particularly promising.mIHC/IF provides high-throughput multiplex staining and standardized quantitative analysis for highly reproducible,efficient and cost-effective tissue studies.This technique has immediate potential for translational research and clinical practice,particularly in the era of cancer immunotherapy. | Wei Chang Colin Tan Sanjna Nilesh Nerurkar Hai Yun Cai Harry Ho Man Ng Duoduo Wu Yu Ting Felicia Wee Jeffrey Chun Tatt Lim Joe Yeong Tony Kiat Hon Lim | 2020 | Cancer Communications2020，40，4： | 11 |
| 6 | Gastric leptomeningeal carcinomatosis: Multi-center retrospective analysis of 54 cases显示文摘AIM: To identify the clinical features and outcomes of infrequently reported leptomeningeal carcinomatosis (LMC) of gastric cancer.METHODS: We analyzed 54 cases of cytologically confirmed gastric LMC at four institutions from 1994 to 2007.RESULTS: The male-to-female ratio was 32:22, and the patients ranged in age from 28 to 78 years (median,48.5 years). The majority of patients had advanced disease at initial diagnosis of gastric cancer. The clini-cal or pathologic tumor, node and metastasis stage ofthe primary gastric cancer wasin 38 patients (70%).The median interval from diagnosis of the primarymalignancy to the diagnosis of LMC was 6.3 mo, rang-ing between 0 and 73.1 mo. Of the initial endoscopic f indings for the 45 available patients, 23 (51%) of the patients were Bormann typeand 15 (33%) patientswere Bormann type. Pathologically, 94% of cases proved to be poorly differentiated adenocarcinomas. Signet ring cell component was also observed in 40% of patients. Headache (85%) and nausea/vomiting (58%) were the most common presenting symptoms of LMC. A gadolinium-enhanced magnetic resonance imaging was conducted in 51 patients. Leptomeningeal enhancement was noted in 45 cases (82%). Intrathecal (IT) chemotherapy was administered to 36 patients-primarily methotrexate alone (61%), but also in combi-nation with hydrocortisone/± Ara-C (39%). The median number of IT treatments was 7 (range, 1-18). Concomitant radiotherapy was administered to 18 patients, and concomitant chemotherapy to seven patients. Sev-enteen patients (46%) achieved cytological negative conversion. Median overall survival duration from the diagnosis of LMC was 6.7 wk (95% CI: 4.3-9.1 wk). In the univariate analysis of survival duration, hemoglobin, IT chemotherapy, and cytological negative conversion showed superior survival duration (P = 0.038, P = 0.010, and P = 0.002, respectively). However, in our multivariate analysis, only cytological negative conversion was predictive of relatively longer survival duration (3.6, 6.7 and 14.6 wk, P = 0.030, RR: 0.415, 95% CI: 0.188-0.918).CONCLUSION: Although these patients had a fatal clinical course, cytologic negative conversion by IT chemotherapy may improve survival. | Sung Yong Oh Su-Jin Lee Jeeyun Lee Suee Lee Sung-Hyun Kim Hyuk-Chan Kwon Gyeong-Won Lee Jung Hun Kang In Gyu Hwang Joung-Soon Jang Ho Yeong Lim Young Suk Park Won Ki Kang Hyo-Jin Kim | 2009 | World Journal of Gastroenterology2009，15，40： | 10 |
| 7 | Overexpression of miR-196b and HOXA10 characterize a poor-prognosis gastric cancer subtype显示文摘AIM:To identify molecular biologic differences between two gastric adenocarcinoma subgroups presenting different prognoses through the analysis of microRNA and protein expression.METHODS:Array technologies were used to generate1146 microRNAs and 124 proteins expression profiles of samples from 60 patients with gastric cancer.For the integrative analysis,we used established mRNA expression data published in our previous study.Whole mRNA expression levels were acquired from microarray data for 60 identical gastric cancer patients.Two gastric adenocarcinoma subgroups with distinct mRNA expression profiles presented distinctly different prognoses.MicroRNA and protein expression patterns were compared between gastric cancer tissue and normal gastric tissue and between two different prognostic groups.Aberrantly expressed microRNA,associated mRNA,and protein in patients with poor-prognosis gastric cancer were validated by quantitative reverse transcription polymerase chain reaction and immunochemistry in independent patients.RESULTS:We obtained the expression data of 1146microRNAs and 124 cancer-related proteins.Four microRNAs were aberrantly expressed in the two prognostic groups and in cancer vs non-cancer tissues(P<0.05).In the poor-prognosis group,miR-196b,miR-135b,and miR-93 were up-regulated and miR-29c*was down-regulated.miR-196b expression positively correlated with Homeobox A10(HOXA10)expression(r=0.726,P<0.001),which was significantly increased in poor-prognosis patients(P<0.001).Comparing gastric cancer with non-cancer tissues,46/124 proteins showed differential expression(P<0.05);COX2(P<0.001)and cyclin B1(P=0.017)were clearly overexpressed in the poor-prognosis group.CONCLUSION:Co-activation of miR-196b and HOXA10characterized a poor-prognosis subgroup of patients with gastric cancer.Elucidation of the biologic function of miR-196b and HOXA10 is warranted. | Jae Yun Lim Sun Och Yoon So-Young Seol Soon Won Hong Jong Won Kim Seung Ho Choi Ju-Seog Lee Jae Yong Cho | 2013 | World Journal of Gastroenterology2013，19，41： | 10 |

| 9 | Retrospective analysis of extra-gastrointestinal stromal tumors显示文摘AIM:To investigate the clinicopathologic features of patients with extra-gastrointestinal stromal tumors(EGISTs)in South Korea.METHODS:A total of 51 patients with an EGIST were identified.The clinicopathologic features,including sex,age,location,tumor size,histology,mitotic rate,immunohistochemical features,genetic status and survival data,were analyzed.RESULTS:The median age was 55 years(range:29-80years),and male:female ratio was 1:1.04.The most common site was in the mesentery(n=15)followed by the retroperitoneum(n=13)and omentum(n=8).The median tumor size was 9.0 cm(range:2.6-30.0cm)and the median mitotic rate was 5.0/50HPF.(1/50-185/50).KIT was analyzed in 16,which revealed 10cases with wild-type KIT and 6 cases with an exon 11mutation.Among 51 patients,31 patients had undergone surgery,and 10 had unresectable disease and had taken palliative imatinib,which resulted in 22.7 mo of progression-free survival.Of the patients who had undergone surgery,18 did not take adjuvant imatinib,and 8 of these were categorized as'high risk'according to the risk criteria.However,the relapse-free survival was not different(P=0.157)between two groups.CONCLUSION:Because the biologic behaviors of GISTs differ according to the location of the tumor,a more stratified strategy is required for managing EGISTs including incorporation of molecular features. | Jun Ho Yi Byeong-Bae Park Jung Hun Kang In Gyu Hwang Dong Bok Shin Sun Jin Sym Hee Kyung Ahn Soon Il Lee Do Hyoung Lim Keon Woo Park Young-Woong Won Sung Hee Lim Se Hoon Park | 2015 | World Journal of Gastroenterology2015，21，6： | 9 |
| 10 | In-situ formation of MOF derived mesoporous Co3N/amorphous N-doped carbon nanocubes as an efficient electrocatalytic oxygen evolution reaction显示文摘The suitable materials,metal nitrides,are a promising class of electrocatalyst materials for a highly efficient oxygen evolution reaction (OER) because they exhibit superior intrinsic conductivity and have higher sustainability than oxide-based materials.To our knowledge,for the first time,we report a designable synthesis of three-dimensional (3D) and mesoporous Co3N@ amorphous N-doped carbon (AN-C) nanocubes (NCs) with well-controlled open-framework structures via monodispersed Co3[Co(CN)6]2 Prussian blue analogue (PBA) NC precursors using in situ nitridation and calcination processes.Co3N@AN-C NCs (2 h) demonstrate better OER activity with a remarkably low Tafel plot (69.6 mV-dec-1),low overpotential of 280 mV at a current density of 10 mA-crrf2.Additionally,excellent cycling stability in alkaline electrolytes was exhibited without morphological changes and voltage elevations,superior to most reported hierarchical structures of transition-metal nitride particles.The presented strategy for synergy effects of metal-organic frameworks (MOFs)-derived transition-metal nitrides-carbon hybrid nanostructures provides prospects for developing high-performance and advanced electrocatalyst materials. | Bong Kyun Kang Seo Young Im Jooyoung Lee Sung Hoon Kwag Seok Bin Kwon SintayehuNibret Tiruneh Min-Jun Kim Jung Ho Kim Woo Seok Yang Byungkwon Lim Dae Ho Yoon | 2019 | Nano Research2019，12，7： | 8 |
| 11 | Predictors of poor outcomes in patients with wild mushroom-induced acute liver injury显示文摘AIM To identify early predictive markers of poor outcomes in patients with acute liver injury from wild mushroom intoxication.METHODS This observational, retrospective record review involved adults aged ≥ 18 years admitted to emergency department with mushroom intoxication from January 2005 to December 2015. The diagnosis of mushroom intoxication was based on the following:(1) a positive history of recent wild mushroom intake(either raw or cooked);(2) the onset of gastrointestinal symptoms, such as watery diarrhea, vomiting, and/or abdominal pain, after ingestion; and(3) the exclusion of other possible causes of acute liver injury. Acute liver injury was defined by a > 5-fold elevation of liver enzymes or moderate coagulopathy [international normalized ratio(INR) > 2.0]. Clinical and laboratory findings were compared in survivors and non-survivors.RESULTS Of 93 patients with mushroom intoxication, 23, 11 men(47.8%) and 12 women(52.2%), of median age 61 years, developed acute liver injury. The overall inhospital mortality rate was 43.5%(10/23). Among thelaboratory variables, mean serum alkaline phosphatase(73.38 ± 10.89 mg/dL vs 180.40 ± 65.39 mg/dL, P < 0.01), total bilirubin(2.312 ± 1.16 mg/dL vs 7.16 ± 2.94 mg/d L, P < 0.01) concentrations and indirect/direct bilirubin(2.45 ± 1.39 mg/dL vs 0.99 ± 0.45 mg/dL, P < 0.01) ratio as well as prothrombin time(1.88 ± 0.83 mg/dL vs 10.43 ± 4.81 mg/dL, P < 0.01), and activated partial thromboplastin time(a PTT; 32.48 ± 7.64 s vs 72.58 ± 41.29 s, P = 0.01), were significantly higher in non-survivors than in survivors. Logistic regression analysis showed that total bilirubin concentration(OR = 3.58, 95%CI: 1.25-10.22), indirect/direct bilirubin ratio(OR = 0.14, 95%CI: 0.02-0.94) and aP TT(OR = 1.30, 95%CI: 1.04-1.63) were significantly associated with mortality. All patients with total bilirubin > 5 mg/dL or aP TT > 50 s on day 3 died.CONCLUSION Monitoring of bilirubin concentrations and a PTT may help in predicting clinical outcomes in patients with acute liver injury from wild mushroom intoxication. | Taerim Kim Danbi Lee Jae Ho Lee Yoon-Seon Lee Bum Jin Oh Kyoung Soo Lim Won Young Kim | 2017 | World Journal of Gastroenterology2017，23，7： | 7 |
| 12 | Signet-ring cell carcinoma arising from a fundic gland polyp in the stomach显示文摘Fundic gland polyps(FGPs)are currently the most common type of gastric polyps and are usually benign.However,although rare,gastric adenocarcinoma of FGP has been recently proposed as a new variant of gastric adenocarcinoma.Here we report the first case of a49-year-old woman with focal signet ring cell carcinoma that arose from an FGP of the stomach.The tumor was completely excised by endoscopic snare polypectomy.FGPs should therefore be evaluated for malignant changes although they occur rarely,if the FGP has an erosive or irregular surface. | Yong Seol Jeong Sung Eun Kim Mi-Jung Kwon Jae Yong Seo Hyun Lim Ji Won Park Ho Suk Kang Sung Hoon Moon Jong Hyuk Kim Choong Kee Park | 2014 | World Journal of Gastroenterology2014，20，47： | 6 |

| 15 | Distribution of dinoflagellate cysts in Yellow Sea sediments显示文摘To investigate the distribution,abundance,and species composition of dinoflagellate cysts in the Yellow Sea,surface sediment samples were collected at 37 sites,including the Korean dump site.Twenty-one dinoflagellate cyst taxa were identified,with the assemblages dominated mainly by Spiniferites bulloideus,Operculodinium centrocarpum,and cyst of Alexandrium catenella/tamarense type.A high frequency of O.centrocarpum in the Yellow Sea was observed for the first time,and it is likely that this can be attributed to the dynamics of the Yellow Sea Cold Water Mass and the Changjiang(Yangtze) River runoff.Total cyst concentrations ranged from 23 to 48 442 cysts/g dry weight,and high cyst concentrations were recorded adjacent to the dumping site.This result suggests that anthropogenic activities such as ocean dumping stimulate the growth of dinoflagellates in the Yellow Sea,which in turn leads to high levels of dinoflagellate cyst production. | SHIN Hyeon Ho LIM Dhongil PARK Soung-Yun HEO Seung KIM So-Young | 2013 | Acta Oceanologica Sinica2013，32，9： | 5 |
| 16 | Treatment for gastric ‘indefinite for neoplasm/dysplasia' lesions based on predictive factors显示文摘BACKGROUND Gastric ‘indefinite for neoplasm/dysplasia'(IFND) is a borderline lesion that is difficult to diagnose as either regenerative or neoplastic. There is a need for guidance in the identification of a subset of patients, who have an IFND lesion with a higher risk of malignant potential, to enable risk stratification and optimal management.AIM To determine the clinical and pathologic factors for the accurate diagnosis of gastric IFND lesions.METHODS In total, 461 gastric lesions diagnosed via biopsy as IFND lesions were retrospectively evaluated. Endoscopic resection(n = 134), surgery(n = 22), and follow-up endoscopic biopsy(n = 305) were performed to confirm the diagnosis.The time interval from initial biopsy to cancer diagnosis was measured, and diagnostic delays were categorized as > 2 wk, > 2 mo, > 6 mo, and > 1 year. The IFND lesions presenting as regenerating atypia(60%) or atypical epithelia(40%)at initial biopsy were adenocarcinomas in 22.6%, adenomas in 8.9%, and gastritis in 68.5% of the cases.RESULTS Four clinical factors [age ≥ 60 years(2.445, 95%CI: 1.305-4.580, P = 0.005),endoscopic size ≥ 10 mm(3.519, 95%CI: 1.891-6.548, P < 0.001), single lesion(5.702, 95%CI: 2.212-14.696, P < 0.001), and spontaneous bleeding(4.056, 95%CI:1.792-9.180, P = 0.001)], and two pathologic factors [atypical epithelium(25.575,95%CI: 11.537-56.695, P < 0.001], and repeated IFND diagnosis [6.022, 95%CI:1.822-19.909, P = 0.003)] were independent risk factors for gastric cancer. With two or more clinical factors, the sensitivity and specificity for carcinoma were91.3% and 54.9%, respectively. Ten undifferentiated carcinomas were initially diagnosed as IFND. In the subgroup analysis, fold change(5.594, 95%CI: 1.458-21.462, P = 0.012) predicted undifferentiated or invasive carcinoma in the submucosal layers or deeper. Diagnostic delays shorter than 1 year were not associated with worse prognoses. Extremely well-differentiated adenocarcinomas accounted for half of the repeated IFND cases and resulted in low diagnostic accuracy even on retrospective blinded review.CONCLUSION More than two clinical and pathologic factors each had significant cut-off values for gastric carcinoma diagnosis; in such cases, endoscopic resection should be considered. | Mi Jung Kwon Ho Suk Kang Hyeon Tae Kim Jin Woo Choo Bo Hyun Lee Sung Eun Hong Kun Ha Park Dong Min Jung Hyun Lim Jae Seung Soh Sung Hoon Moon Jong Hyeok Kim Hye-Rim Park Soo Kee Min Jin won Seo Ji-Young Choe | 2019 | World Journal of Gastroenterology2019，25，4： | 4 |
| 17 | Can intravesical prostatic protrusion predict bladder outlet obstruction even in men with good flow?显示文摘Objective:Men with benign prostate hyperplasia(BPH)with good urinary flow may still have bladder outlet obstruction(BOO).Intravesical prostatic protrusion(IPP)has been shown to be able to predict BOO.We aim to investigate the use of IPP to predict BOO in men with good urinary flow.Methods:One hundred and fourteen consecutive men(>50 years old)presenting with lower urinary tract symptoms suggestive of BPH were recruited in 2001 and 2002.They were evaluated with serum prostate specific antigen(PSA),uroflowmetry and transabdominal ultrasound measurement of IPP and prostate volume(PV).Pressure-flow urodynamic studies were performed on all men and BOO was defined by BOO index>40.Men with Qmax12.0 mL/s were considered to have good flow.Results:Among the 114 men,61 patients had good urinary flow.Their median age,PV and Qmax were 66 years,32.9 mm3 and 14.5 mL/s respectively.14/61(23.0%)patients had BOO and their distribution of IPP were as follows:Grade 1 e 0/20(0%)obstructed,Grade 2 e 6/22(27.3%)and Grade 3 e 8/19(42.1%).Sensitivity of Grade 2/3 IPP for BOO was 100% while specificity of Grade 3 IPP was 76.6%.The area-under-curve(AUC)for IPP was greater than that for PV(0.757 vs.0.696).Conclusion:Even in men with good flow,high grades of IPP were more likely to have BOO and hence,may be a useful adjunct to predict BOO. | Alvin Lee Han Jie Lee Kok Bin Lim Hong Hong Huang Henry Ho Keong Tatt Foo | 2016 | Asian Journal of Urology2016，3，1： | 4 |
| 18 | Endoscopic submucosal dissection vs endoscopic mucosal resection for colorectal polyps:A meta-analysis and metaregression with single arm analysis显示文摘BACKGROUND Endoscopic submucosal dissection(ESD)has shown to be effective in management of colorectal neoplasm in the Asian countries,while its implementation in Western countries where endoscopic mucosal resection(EMR)is preferred is still debatable.AIM To compare the surgical,histological,and oncological outcomes between ESD and EMR in the treatment of colorectal polyps,with subgroup analysis comparing the efficacy of ESD and EMR between Japan and the rest of the world.METHODS Embase and Medline databases were searched from inception to October 2020 in accordance with PRISMA guidelines for studies comparing en bloc,complete resection,margin involvement,resection time,need for additional surgery,complications,and recurrence rate of ESD with EMR.RESULTS Of 281344 colorectal polyps from 21 studies were included.When compared to EMR,the pooled analysis revealed ESD was associated with higher en bloc and complete resection rate,and lower lateral margin involvement and recurrence.ESD led to increased procedural time,need for additional surgery,and perforation risk.No significant difference in bleeding risk was found between the two groups.Meta-regression analysis suggested only right colonic polyps correlated with an increased perforation risk in ESD.Confounders including polyp size and invasion depth did not significantly influence the en bloc and complete resection rate,bleeding risk and recurrence.In subgroup analysis,Japan performed better than the rest of the world in both ESD and EMR with perforation risk of 4%and 0.0002%,respectively,as compared to perforation risk of 8%and 1%,respectively,in reports coming from rest of the world.CONCLUSION ESD resulted in better resection outcomes and lower recurrence compared to EMR.With appropriate training,ESD is preferred over EMR as the first-line therapy for resection of colorectal polyps,without restricting to lesions greater than 20 mm and those with high suspicion of submucosal invasion. | Xiong Chang Lim Kameswara Rishi Yeshayahu Nistala Cheng Han Ng Snow Yunni Lin Darren Jun Hao Tan Khek-Yu Ho Choon-Seng Chong Mark Muthiah | 2021 | World Journal of Gastroenterology2021，27，25： | 4 |

| 20 | Thioredoxin and thioredoxin-interacting protein as prognostic markers for gastric cancer recurrence显示文摘AIM:To evaluate the potential of thioredoxin (TXN) and thioredoxin-interacting protein (TXNIP) expression as biomarkers for predicting gastric cancer recurrence. METHODS:TXN and TXNIP expression levels were acquired from gene expression microarray data for 65 human gastric cancer tissues. We determined whether each gene expression level was associated with cancer recurrence and investigated the relationship between the two genes. For validation, the expression levels of TXN and TXNIP were measured by quantitative real- time reverse transcription polymerase chain reaction in 68 independent stage Ⅲ gastric cancer patients. The correlation between gene expression and cancer prognosis was evaluated. Immunohistochemical staining was performed to investigate the protein expression levels of TXN and TXNIP and to characterize the expression patterns of each protein. RESULTS:TXN was a prognosis-related gene (P = 0.009), whereas TXNIP, a TXN inhibitor, demonstrated a negative correlation with TXN in the gene expression microarray data. In the 68 stage Ⅲ patients, the expression levels of both TXN and TXNIP had a statistically significant effect on recurrence-free survival (RFS, P = 0.008 and P = 0.036, respectively). The low TXN and high TXNIP expression group exhibited a better prognosis than the other groups, and the high TXN and low TXNIP expression group exhibited a poorer prognosis (P < 0.001 for RFS and P = 0.001 for overall survival). More than half of the patients in the simulta-neously high TXN and low TXNIP expression group ex- perienced a recurrence within 1 year after curative surgery, and the 5-year survival rate of the patients in this group was 29%, compared with 89% in the low TXN and high TXNIP expression group. The TXN protein was overexpressed in 65% of the gastric cancer tissues, whereas the TXNIP protein was underexpressed in 85% of the cancer cells. In a correlation analysis, TXN and TXNIP were highly correlated with many oncogenes and tumor suppressors as well as with genes related to energy, protein synthesis and autophagy. CONCLUSION:TXN and TXNIP are promising prognostic markers for gastric cancer, and performing personalized adjuvant treatment based on TXN and TXNIP expression levels would be an effective practice in the treatment of gastric cancer. | Jae Yun Lim Sun Och Yoo Soon Won Hong Jong Won Kim Seung Ho Choi Jae Yong Cho | 2012 | World Journal of Gastroenterology2012，18，39： | 4 |
