2Benefit of neoadjuvant concurrent chemoradiotherapy for locally advanced perihilar cholangiocarcinoma显示文摘AIM To clarify the role of neoadjuvant concurrent chemoradiotherapy(NACCRT) followed by surgical resection for localized or locally advanced perihilar cholangiocarcinoma(CCA).METHODS We retrospectively reviewed 57 patients who underwent surgical resection with or without NACCRT for perihilar CCA; 12 patients received NACCRT and 45 patients did not received NACCRT. Patients with locally advanced perihilar CCA requiring NACCRT were defined as follows:(1) a mass involving unilateral branches of the portal vein or hepatic artery with insufficient volume of the anticipated remnant lobe; or(2) an infiltrating mass in the main portal vein that was too long for reconstruction, identified at preoperative staging. RESULTS The median disease-free survival(DFS) durations of the neoadjuvant and non-neoadjuvant CCRT groups were26.0 and 15.1 mo, respectively(P = 0.91). The median overall survival(OS) durations of the neoadjuvant and non-neoadjuvant CCRT groups were 32.9 and 27.1 mo, respectively(P = 0.26). The NACCRT group showed a downstaging tendency compared to the non-NACCRT group as compared with the tumor stage confirmed by histological examination after surgery and the tumor stage confirmed by imaging test at the time of diagnosis(P = 0.01). CONCLUSION NACCRT does not prolong DFS and OS in localized or locally advanced perihilar CCA. However, NACCRT may allow tumor downstaging and improve tumor resectability.Jang Han Jung Hyun Jik Lee Hee Seung Lee Jung Hyun Jo In Rae Cho Moon Jae Chung Jeong Youp Park Seung Woo Park Si Young Song Seungmin Bang 2017World Journal of Gastroenterology2017,23,18:21
3Prevalence 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
4Safety and efficacy of tenofovir in chronic hepatitis B-related decompensated cirrhosis显示文摘AIM To evaluate the safety and efficacy of tenofovir disoproxil fumarate(TDF) as a first-line therapy in decompensated liver disease. METHODS We enrolled 174 chronic hepatitis B-related liver cirrhosis patients treated with 300 mg/d TDF at six Korean centers. Of the 174 cirrhosis patients, 57 were assigned to the decompensated cirrhosis group and 117 were assigned to the compensated cirrhosis group. We followed the patients for 12 mo and evaluated clinical outcomes, including biochemical, virological, and serological responses. We also evaluated changes in hepatic and renal function and compared the decompensated and compensated cirrhosis groups. RESULTS The 1-year complete virological response(CVR) and Hepatitis B e antigen(HBe Ag) seroconversion were seen in 70.2% and 14.2% in the decompensated cirrhosis group, respectively. The rates of HBe Ag seroconversion/loss and ALT normalization at month 12 were similar in both groups. TDF treatment was also effective for decreasing the level of hepatitis B virus(HBV) DNA in both groups, but CVR was higher in the compensated group(88.9% vs 70.2%, P = 0.005). Tenofovir treatment for 12 mo resulted in improved Child-Turcotte-Pugh(CTP) and model for end-stage liver disease(MELD) scores in decompensated group(P < 0.001). Of the 57 decompensated patients, 39(68.4%) achieved CTP class A and 27(49.1%) showed improvement in the CTP score of 2 points after 12 mo of TDF. The observed rate of confirmed 0.5 mg/d L increases in serum levels of creatinine in the decompensated and compensated cirrhosis group were 7.0% and 2.5%, respectively(P < 1.000).CONCLUSION TDF therapy in decompensated cirrhosis patients was effective for decreasing HBV DNA levels and improving hepatic function with relatively lower CVR than in compensated cirrhosis. Thus, physicians should carefully monitor not only renal function but also treatment responses when using TDF in decompensated cirrhosis patients.Soon Kyu Lee Myeong Jun Song Seok Hyun Kim Byung Seok Lee Tae Hee Lee Young Woo Kang Suk Bae Kim Il Han Song Hee Bok Chae Soon Young Ko Jae Dong Lee 2017World Journal of Gastroenterology2017,23,13:14
5Management of entecavir-resistant chronic hepatitis B with adefovir-based combination therapies显示文摘AIM: To evaluate the long-term efficacy adefovir(ADV)-based combination therapies in entecavir(ETV)-resistant chronic hepatitis B(CHB) patients. METHODS: F i fty CHB pat ient s wi t h genotypic resistance to ETV at 13 medical centers in South Korea were included for the analysis. All the patients received rescue therapy with the combination of ADV plus ETV(ADV/ETV,n = 23) or ADV plus lamivudine(LMV)(ADV/LMV,n = 27) for more than 12 mo. Patients were monitored at least every 3-4 mo during ADV-based combination therapy by clinical examination as well as biochemical and virological assessments. Hepatitis B virus(HBV) DNA levels were measured by realtime PCR and logarithmically transformed for analysis. Cumulative rates of virologic response(VR; HBV DNA < 20 IU/m L) were calculated using the Kaplan-Meier method,and the difference was determined by a logrank test. Multivariate logistic regression and Cox proportional hazards models were used to identify independent risk factors significantly associated with short-term and long-term VR,respectively.RESULTS: Baseline median HBV DNA levels were 5.53(2.81-7.63) log10 IU/m L. The most commonly observed ETV genotypic mutation sites were rt184 and rt202. Patients were treated for a median of 27(12-45) mo. Overall,cumulative VR rates at 6,12,24,and 36 mo were 26%,36%,45%,and 68%,respectively. Patients treated with the ADV/ETV combination showed higher cumulative VR rates(35%,43%,65%,and 76%,respectively) than those with the ADV/LAM combination(18%,30%,30%,and 62%,respectively; P = 0.048). In the multivariate analysis,low baseline HBV DNA levels(< 5.2 log10 IU/m L) and initial virologic response at 3 mo(IVR-3; HBV DNA < 3.3 log10 IU/m L after 3 mo) were independent predictive factors for VR. Patients with favorable predictors achieved cumulative VR rates up to 90% at 36 mo. During the same period,the cumulative incidence of virologic breakthrough was as low as 6% in patients with the both favorable predictors.CONCLUSION: If tenofovir is not available,ADV/ETV combination could be considered in ETV-resistant patients with low HBV DNA titers,and may becontinued if IVR-3 is achieved.Hyoung Su Kim Hyung Joon Yim Myoung Kuk Jang Ji Won Park Sang Jun Suh Yeon Seok Seo Ji Hoon Kim Bo Hyun Kim Sang Jong Park Sae Hwan Lee Sang Gyune Kim Young Seok Kim Jung Il Lee Jin-Woo Lee In Hee Kim Tae Yeob Kim Jin-Wook Kim Sook-Hyang Jeong Young Kul Jung Hana Park Seong Gyu Hwang 2015World Journal of Gastroenterology2015,21,38:13
6Plasma levels of acylated ghrelin in patients with functional dyspepsia显示文摘AIM:To investigate the relationship between plasma acylated ghrelin levels and the pathophysiology of functional dyspepsia.METHODS:Twenty-two female patients with functional dyspepsia and twelve healthy volunteers were recruited for the study.The functional dyspepsia patients were each diagnosed based on the Rome Ⅲ criteria.Eligible patients completed a questionnaire concerning the severity of 10 symptoms.Plasma acylated ghrelin levels before and after a meal were determined in the study participants using a commercial human acylated enzyme immunoassay kit;electrogastrograms were performed for 50 min before and after a standardized 10-min meal containing 265 kcal.RESULTS:There were no significant differences in plasma acylated ghrelin levels between healthy volunteers and patients with functional dyspepsia.However,in patients with functional dyspepsia,there was a negative correlation between fasting plasma acylated ghrelin levels and the sum score of epigastric pain(r =-0.427,P = 0.047) and a positive correlation between the postprandial/fasting plasma acylated ghrelin ratio and the sum score of early satiety(r = 0.428,P =0.047).Additionally,there was a negative correlation between fasting acylated ghrelin plasma levels and fasting normogastria(%)(r =-0.522,P = 0.013).Interestingly,two functional dyspepsia patients showed paradoxically elevated plasma acylated ghrelin levels after the meal.CONCLUSION:Abnormal plasma acylated ghrelin levels before or after a meal may be related to several of the dyspeptic symptoms seen in patients with functional dyspepsia.Yeon Soo Kim Joon Seong Lee Tae Hee Lee Joo Young Cho Jin Oh Kim Wan Jung Kim Hyun Gun Kim Seong Ran Jeon Hoe Su Jeong 2012World Journal of Gastroenterology2012,18,18:12

8Endoscopic features suggesting gastric cancer in biopsy-proven gastric adenoma with high-grade neoplasia显示文摘AIM:To elucidate the endoscopic features that predict the cancer following endoscopic submucosal dissection(ESD)in patients with high-grade neoplasia(HGN).METHODS:We retrospectively analyzed the medical records of patients who underwent ESD of gastric neoplasms from January 2007 to September 2010.ESD was performed in 555 cases involving 550 patients.A total of 112 lesions from 110 consecutive patients were initially diagnosed as HGN without cancer by forceps biopsy,and later underwent ESD.We classified lesions into two groups according to histologic discrepancies between the biopsy and ESD diagnosis.Gastric adenoma in the final diagnosis by ESD specimens were defined as adenoma group.Lesions with coexisting cancer after ESD were defined as cancer group.RESULTS:The mean age was 65.3 years,and 81 patients were male.There was no significant difference in the age or gender distribution between the adenoma(n=52)and cancer(n=60)groups.Thirty-six of these lesions(32.1%)showed histologic concordance between the forceps biopsy and ESD specimens,16(14.3%)showed a downgraded histology(low-grade neoplasia),and 60(53.6%)showed an upgraded histology(cancer).A red color change of the mucosal surface on endoscopy was found in 27/52(51.9%)of cases in the adenoma group and in 46/60(76.7%)of cases in the cancer group(P=0.006).Ulceration of the mucosal surface on endoscopy was found in 5(9.6%)of 52 lesions in the adenoma group and in 17(28.3%)of 60 lesions in the cancer group(P=0.013).In the multivariate analysis,a reddish surface color change and mucosal ulceration were significant predictive factors correlated with cancer after ESD of the HGN by forceps biopsy.CONCLUSION:HGN with a red color change or mucosal ulceration correlated with the presence of gastric cancer.These finding may help to guide the diagnosis and treatment.Jung Ho Kim Yoon Jae Kim Jungsuk An Jong Joon Lee Jae Hee Cho Kyoung Oh Kim Jun-Won Chung Kwang An Kwon Dong Kyun Park Ju Hyun Kim 2014World Journal of Gastroenterology2014,20,34:10
9Adjuvant capecitabine and oxaliplatin for gastric cancer after D2 gastrectomy (CLASSIC): a phase 3 open-label, randomised controlled trial显示文摘Yung-Jue Bang Young-Woo Kim Han-Kwang Yang Hyun Cheol Chung Young-Kyu Park Kyung Hee Lee Keun-Wook Lee Yong Ho Kim Sang-Ik Noh Jae Yong Cho Young Jae Mok Yeul Hong Kim Jiafu Ji Ta-Sen Yeh Peter Button Florin Sirzén Sung Hoon Noh 2012The Lancet2012,,9813:10
10Colonoscopy-induced ischemic colitis in patients without risk factors显示文摘Ischemic colitis is the most common form of intestinal ischemia.It is a condition that is commonly seen in the elderly and among individuals with risk factors for ischemia.Common predisposing conditions for ischemic colitis are major vascular occlusion,small vessel disorder,shock,some medications,colonic obstructions and hematologic disorders.Ischemic colitis following colonoscopy is rare.Here,we report two cases of ischemic colitis after a routine screening colonoscopy in patients without risk factors for ischemia.Sang Ok Lee Sae Hee Kim Sung Hee Jung Chan Woong Park Min Ji Lee Jin A Lee Hyun Cheol Koo Anna Kim Hyun-Young Han Dong-Wook Kang 2014World Journal of Gastroenterology2014,20,13:9
11Peroxisome proliferator-activated receptor-delta agonist ameliorated inflammasome activation in nonalcoholic fatty liver disease显示文摘AIM: To evaluate the inflammasome activation and the effect of peroxisome proliferator-activated receptors(PPAR)-δ agonist treatment in nonalcoholic fatty liver disease(NAFLD) models.METHODS: Male C57BL/6J mice were classified according to control or high fat diet(HFD) with or without PPAR-δ agonist(GW) over period of 12 wk [control, HFD, HFD + lipopolysaccharide(LPS), HFD + LPS + GW group]. Hep G2 cells were exposed to palmitic acid(PA) and/or LPS in the absence or presence of GW.RESULTS: HFD caused glucose intolerance and hepatic steatosis. In mice fed an HFD with LPS, caspase-1 and interleukin(IL)-1β in the liver were significantly increased. Treatment with GW ameliorated the steatosis and inhibited overexpression of pro-inflammatory cytokines. In Hep G2 cells, PA and LPS treatment markedly increased m RNA of several nucleotide-binding andoligomerization domain-like receptor family members(NLRP3, NLRP6, and NLRP10), caspase-1 and IL-1β. PA and LPS also exaggerated reactive oxygen species production. All of the above effects of PA and LPS were reduced by GW. GW also enhanced the phosphorylation of AMPK-α.CONCLUSION: PPAR-δ agonist reduces fatty acidinduced inflammation and steatosis by suppressing inflammasome activation. Targeting the inflammasome by the PPAR-δ agonist may have therapeutic implication for NAFLD.Hyun Jung Lee Jong Eun Yeon Eun Jung Ko Eileen L Yoon Sang Jun Suh Keunhee Kang Hae Rim Kim Seoung Hee Kang Yang Jae Yoo Jihye Je Beom Jae Lee Ji Hoon Kim Yeon Seok Seo Hyung Joon Yim Kwan Soo Byun 2015World Journal of Gastroenterology2015,21,45:9
12Durability of viral response after off-treatment in HBeAg positive chronic hepatitis B显示文摘AIM:To evaluate the durability in hepatitis B e antigen (HBeAg) positive chronic hepatitis B patients who discontinued antiviral treatment. METHODS:A total of 48 HBeAg positive chronic hepatitis B patients who were administered nucleoside analogues and maintained virological response for ≥ 6 mo [hepatitis B virus (HBV) DNA < 300 copies/mL and HBeAg seroconversion] before cessation of treatment were enrolled between February 2007 and January 2010. The criteria for the cessation of the antiviral treatment were defined as follows:(1) achievement of virological response; and (2) duration of consolidation therapy (≥ 6 mo). After treatment cessation, the patients were followed up at 3-6 mo intervals. The primary endpoint was serologic and virologic recurrence rates after withdrawal of antiviral treatment. Serologic recurrence was defined as reappearance of HBeAg positivity after HBeAg seroconversion. Virologic recurrence was defined as an increase in HBV-DNA level > 104 copies/mL after HBeAg seroconversion with previously undetectable HBV-DNA level. RESULTS:During the median follow-up period of 18.2 mo (range:5.1-47.5 mo) after cessation of antiviral treatment, the cumulative serological recurrence rate was 15 % at 12 mo. The median duration between the cessation of antiviral treatment and serologic recurrence was 7.2 mo (range:1.2-10.9 mo). Of the 48 patients with HBeAg positive chronic hepatitis, 20 (41.6%) showed virological recurrence. The cumulative virologic recurrence rates at 12 mo after discontinuing the antiviral agent were 41%. The median duration between off-treatment and virologic recurrence was 7.6 mo (range:4.3-27.1 mo). The mean age of the virological recurrence group was older than that of the non-recurrence group (46.7 ± 12.1 years vs 38.8 ± 12.7 years, respectively; P = 0.022). Age (> 40 years) and the duration of consolidation treatment (≥ 15 mo) were significant predictive factors for offtreatment durability in the multivariate analysis [P = 0.049, relative risk (RR) 0.31, 95% CI (0.096-0.998) and P = 0.005, RR 11.29, 95% CI (2.054-65.12), respectively]. Patients with age (≤ 40 years) who received consolidation treatment (≥ 15 mo) significantly showed durability in HBeAg positive chronic hepatitis B patients (P = 0.014). These results suggest that additional treatment for more than 15 mo after HBeAg seroconversion in patients who are ≤ 40 years old may be beneficial in providing a sustained virological response. CONCLUSION:Our data suggest that HBeAg seroconversion is an imperfect end point in antiviral treatment. Long-term consolidation treatment (≥ 15 mo) in younger patients is important for producing better prognosis in HBeAg positive chronic hepatitis B.Myeong Jun Song Do Seon Song Hee Yeon Kim Sun Hong Yoo Si Hyun Bae Jong Young Choi Seung Kew Yoon Yong-Han Paik June Sung Lee Hyun Woong Lee Hyung Joon Kim 2012World Journal of Gastroenterology2012,18,43:7
13Risk factors and therapeutic results of early local recurrence after transcatheter arterial chemoembolization显示文摘AIM:To identify factors affecting early local recurrence after transcatheter arterial chemoembolization(TACE)and investigate treatments and outcomes for local recurrence.METHODS:Early local recurrence and no early local recurrence groups drawn from 134 patients who were initially diagnosed with hepatocellular carcinoma(HCC)and showed a complete response(CR)to TACE treatment between January 1,2006,and January 31,2012,were analyzed by univariate and multivariate analyses.Additionally,the subsequent treatment for patients with recurrence was analyzed,and in cases in which TACE had been performed,the cumulative recurrence rates were calculated using the Kaplan-Meier method and compared with those of the primary lesion.RESULTS:The 1-,2-,and 3-year survival rates were92.3%,60.2%,and 39.8%,respectively,in the earlylocal recurrence group,which were significantly lower than those in both the late local and no local recurrence groups(P<0.001).On multivariate analyses,non-compact lipiodol uptake,large tumor size,and an alpha-fetoprotein>20 ng/mL after achieving a CR were significant predictors.When TACE was performed for early and late locally recurrent lesions,a CR was observed in 15 patients(41.7%)and 11 patients(78.6%),and the cumulative recurrence rates at 6,12,and 24mo were 17.9%,43.3%,and 71.2%,respectively,which did not differ significantly from those after the first CR of 20.5%,44.0%,and 58.6%,respectively(P=0.639).CONCLUSION:Closer monitoring and active treatments must be provided to patients with risk factors for early local recurrence of HCC.Woo Sun Rou Byung Seok Lee Hee Seok Moon Eaum Seok Lee Seok Hyun Kim Heon Young Lee 2014World Journal of Gastroenterology2014,20,22:7
14Outcome of transarterial chemoembolization-based multi-modal treatment in patients with unresectable hepatocellular carcinoma显示文摘AIM:To investigate the efficacy and safety of transarterial chemoembolization(TACE)-based multimodal treatment in patients with large hepatocellular carcinoma(HCC).METHODS:A total of 146 consecutive patients were included in the analysis,and their medical records and radiological data were reviewed retrospectively.RESULTS:In total,119 patients received TACE-based multi-modal treatments,and the remaining 27 received conservative management.Overall survival(P<0.001)and objective tumor response(P=0.003)were significantly better in the treatment group than in the conservative group.After subgroup analysis,survival benefits were observed not only in the multi-modal treatment group compared with the TACE-only group(P=0.002)but also in the surgical treatment group compared with the loco-regional treatment-only group(P<0.001).Multivariate analysis identified tumor stage(P<0.001)and tumor type(P=0.009)as two independent pre-treatment factors for survival.After adjusting for significant pre-treatment prognostic factors,objective response(P<0.001),surgical treatment(P=0.009),and multi-modal treatment(P=0.002)were identified as independent post-treatment prognostic factors.CONCLUSION:TACE-based multi-modal treatments were safe and more beneficial than conservative management.Salvage surgery after successful downstaging resultedin long-term survival in patients with large,unresectable HCC.Do Seon Song Soon Woo Nam Si Hyun Bae Jin Dong Kim Jeong Won Jang Myeong Jun Song Sung Won Lee Hee Yeon Kim Young Joon Lee Ho Jong Chun Young Kyoung You Jong Young Choi Seung Kew Yoon 2015World Journal of Gastroenterology2015,21,8:7
15Asymptomatic lymphangioma involving the spleen and retroperitoneum in adults显示文摘Lymphangioma,a benign neoplasm of the lymphatic system,is common in children but rare in adults.Its clinical manifestations include abdominal pain,nausea, vomiting and a palpable mass.However,abdominal sonography or abdominal computed tomography(CT) scan can also incidentally reveal lymphangioma.A larger or symptomatic lymphangioma is treated with total resection to prevent recurrence,infection,torsion and enlargement.Although lymphangioma rarely becomes malignant,its prognosis is generally good. We report a cystic lymphangioma of the spleen and retroperitoneum,which was incidentally found in a 56-year-old man who was hospitalized due to a colon mass.Physical examination showed no specific findings.Abdominal CT revealed a 5.7 cm,non-enhanced multilobulated cystic mass with multiple septa in the spleen and a 10 cm lobulated cystic mass in the paraaortic area.Splenectomy and retroperitoneal resection of the cystic mass were conducted.The endotheliumof splenic and retroperitoneal cyst was immunohisto- chemically stained with D2-40 antibody.The patient was finally diagnosed with splenic cystic and retroperitoneal cavernous lymphangioma.Sook Hee Chung Young Sook Park Yun Ju Jo Seong Hwan Kim Dae Won Jun Byoung Kwan Son Jun Young Jung Dae Hyun Baek Dong Hee Kim Yoon Young Jung Won Mi Lee 2009World Journal of Gastroenterology2009,15,44:7

17Clinical course of subepithelial lesions detected on upper gastrointestinal endoscopy显示文摘AIM:To evaluate the natural history of subepithelial lesions.METHODS:We reviewed the medical records of 104 159 patients who underwent upper gastrointestinal endoscopy at the Center for Health Promotion of Samsung Medical Center between 1996 and 2003.Subepithelial lesions were detected in 795 patients(0.76%);252 patients were followed using upper gastrointestinal endoscopy for 82.5 ± 29.2 mo(range,12-160 mo;median,84 mo;1st quartile,60 mo;3rd quartile,105 mo).The median interval of follow-up endoscopy was 12 mo(range,6-105 mo;1st quartile,12 mo;3rd quartile,24 mo).RESULTS:The mean patient age was 53 years(range,22-80 years),and the male-to-female ratio was 2.36:1(177/75).The lesion size at initial measurement averaged 8.9 mm(range,2-25 mm;median,8 mm;1st quartile,5 mm;3rd quartile,10 mm).Of the 252 lesions,244(96.8%) were unchanged and 8(3.2%) were significantly increased in size(from 12.9 ± 6.0 to 21.2 ± 12.2 mm) after a mean interval of 59.1 ± 27.5 mo(range,12-86 mo).Surgical resection of lesions was performed when the lesions were ≥ 3 cm in diameter.Two lesions were diagnosed as gastrointestinal stromal tumors with an intermediate or high risk of malignancy and one lesion was classified as a schwannoma.CONCLUSION:Most small subepithelial lesions do not change as shown by endoscopic examination,and regular follow-up with endoscopy may be considered in small,subepithelial lesions,especially lesions < 1 cm in size.Yeun Jung Lim Hee Jung Son Jong-Soo Lee Young Hye Byun Hyun Joo Suh Pool Lyul Rhee Jae J Kim Jong Chul Rhee 2010World Journal of Gastroenterology2010,16,4:6
18Streptococcus mutans activates the AIM2, NLRP3 and NLRC4 inflammasomes in human THP-1 macrophages显示文摘Streptococcus mutans(S. mutans), a major aetiologic agent of dental caries, is involved in systemic diseases, such as bacterial endocarditis, if it enters the bloodstream through temporary bacteraemia. Interleukin(IL)-1β, a proinflammatory cytokine, is related to the host defences against pathogens, and its synthesis, maturation, and secretion are tightly regulated by the activation of the inflammasome, an inflammatory signalling complex. This study examined the signalling mechanism of IL-1β secretion and the inflammasome pathway induced by S. mutans to explain the molecular mechanism through which systemic infection by oral streptococci can occur. After infection of THP-1 cells with S. mutans, the expression of inflammasome components was detected using various methods. S. mutans induced IL-1β secretion via caspase-1 activation, and S. mutans-induced IL-1β secretion required absent in melanoma(AIM2), NLR family pyrin domain-containing 3(NLRP3) and NLR family CARD domain-containing 4(NLRC4)inflammasome activation. In particular, the S. mutans-induced NLRP3 inflammasome was mediated by adenosine triphosphate(ATP) release, potassium depletion and lysosomal damage. Our study provides novel insight into the innate immune response against S. mutans infection.Yuri Song Hee Sam Na Eunjoo Park Mi Hee Park Hyun Ah Lee Jin Chung 2018International Journal of Oral Science2018,10,3:6
19Differential diagnosis of left-sided abdominal pain:Primary epiploic appendagitis vs colonic diverticulitis显示文摘AIM:To investigate the clinical characteristics of left primary epiploic appendagitis and to compare them with those of left colonic diverticulitis.METHODS:We retrospectively reviewed the clinical records and radiologic images of the patients who presented with left-sided acute abdominal pain and had computer tomography(CT) performed at the time of presentation showing radiological signs of left primary epiploic appendagitis(PEA) or left acute colonic diverticulitis(ACD) between January 2001 and December 2011. A total of 53 consecutive patients were enrolled and evaluated. We also compared the clinical characteristics,laboratory findings,treatments,and clinical results of left PEA with those of left ACD.RESULTS:Twenty-eight patients and twenty-five patients were diagnosed with symptomatic left PEA and ACD,respectively. The patients with left PEA had focal abdominal tenderness on the left lower quadrant(82.1%). On CT examination,most(89.3%) of the patients with left PEA were found to have an oval fatty mass with a hyperattenuated ring sign. In cases of left ACD,the patients presented with a more diffuse abdominal tenderness throughout the left side(52.0%vs 14.3%; P = 0.003). The patients with left ACD had fever and rebound tenderness more often than those with left PEA(40.0% vs 7.1%,P = 0.004; 52.0% vs14.3%,P = 0.003,respectively). Laboratory abnormalities such as leukocytosis were also more frequently observed in left ACD(52.0% vs 15.4%,P = 0.006).CONCLUSION:If patients have left-sided localized abdominal pain without associated symptoms or laboratory abnormalities,clinicians should suspect the diagnosis of PEA and consider a CT scan.Jeong Ah Hwang Sun Moon Kim Hyun Jung Song Yu Mi Lee Kyung Min Moon Chang Gi Moon Hoon Sup Koo Kyung Ho Song Yong Seok Kim Tae Hee Lee Kyu Chan Huh Young Woo Choi Young Woo Kang Woo Suk Chung 2013World Journal of Gastroenterology2013,19,40:6
20Does immunohistochemical staining have a clinical impact in early gastric cancer conducted endoscopic submucosal dissection?显示文摘AIM: To evaluate clinicopathologic parameters and the clinical significance related lymphovascular invasion (LVI) by immunohistochemical staining (IHCS) in endoscopic submucosal dissection (ESD). METHODS: Between May 2005 and May 2010, a total of 348 lesions from 321 patients (mean age 63 ± 10 years, men 74.6%) with early gastric cancer (EGC) who met indication criteria after ESD were analyzed retrospectively. The 348 lesions were divided into the absolute (n = 100, differentiated mucosal cancer without ulcer ≤ 20 mm) and expanded (n = 248) indica-tion groups after ESD. The 248 lesions were divided into four subgroups according to the expanded ESD indication. The presence of LVI was determined by factor Ⅷ-related antigen and D2-40 assessment. We compared LVI IHCS-negative group with LVI IHCSpositive in each group. RESULTS: LVI by hematoxylin-eosin staining (HES) and IHCS were all negative in the absolute group, while was observed in only the expanded groups. The positive rate of LVI by IHCS was higher than that of LVI by HES (n = 1, 0.4% vs n = 11, 4.4%, P = 0.044). LVI IHCS-positivity was observed when the cancer invaded to the mucosa 3 (M3) or submucosa 1 (SM1) levels, with a predominance of 63.6% in the subgroup that included only SM1 cancer (P < 0.01). In a univariate analysis, M3 or SM1 invasion by the tumor was significantly associated with a higher rate of LVI by IHCS, but no factor was significant in a multivariate analysis. There were no cases of tumor recurrence or metastasis during the median 26 mo follow-up. CONCLUSION: EGCs of the absolute group are immunohistochemically stable. The presence of LVI may be carefully examined by IHCS in an ESD expanded indication group with an invasion depth of M3 or greater.Seong Ran Jeon Joo Young Cho Gene Hyun Bok Tae Hee Lee Hyun Gun Kim Won Young Cho So Young Jin Yeon Soo Kim 2012World Journal of Gastroenterology2012,18,33:6
