5Expression of heat shock proteins (HSP27, HSP60, HSP70, HSP90, GRP78, GRP94) in hepatitis B virus-related hepatocellular carcinomas and dysplastic nodules显示文摘AIM: Expression of heat shock proteins (HSPs) is frequently up-regulated in hepatocellular carcinoma (HCC), which evolves from dysplastic nodule (DN) and early HCC to advanced HCC. However, little is known about the differential expression of HSPs in multistep hepatocarcinogenesis. It was the purpose of this study to monitor the expression of HSPs in multistep hepatocarcinogenesis and to evaluate their prognostic significance in hepatitis B virus (HBV)related HCC.METHODS: Thirty-eight HCC and 19 DN samples were obtained from 52 hepatitis B surface antigen-positive Korean patients. Immunohistochemical and dot immunoblot analyses of HSP27, HSP60, HSP70, HSP90, glucoseregulated protein (GRP)78, and GRP94 were performed and their expression at different stages of HCC development was statistically analyzed.RESULTS: Expression of HSP27, HSP70, HSP90, GRP78, and GRP94 increased along with the stepwise progression of hepatocarcinogenesis. Strong correlation was found only in GRP78 (Spearman's r= 0.802). There was a positive correlation between the expressions of GRP78, GRP94, HSP90, or HSP70 and prognostic factors of HCC. Specifically, the expression of GRP78, GRP94, or HSP90 was associated significantly with vascular invasion and intrahepatic metastasis.CONCLUSION: The expressions of HSPs are commonly up-regulated in HBV-related HCCs and GRP78 might play an important role in the stepwise progression of HBVrelated hepatocarcinogenesis. GRP78, GRP94, and HSP90 may be important prognostic markers of HBV-related HCC, strongly suggesting vascular invasion and intrahepatic metastasis.Seung Oe Lim Sung Gyoo Park Jun-Hi Yoo Young Min Park Hie-Joon Kim Kee-Taek Jang Jae Won Cho Byung Chul Yoo Gu-Hung Jung Cheol Keun Park 2005World Journal of Gastroenterology2005,11,14:62

7Systematic review on the surgical treatment for T1 gallbladder cancer显示文摘AIM:To evaluate the efficacy of simple and extended cholecystectomy for mucosa(T1a) or muscularis(T1b) gallbladder(GB) cancer. METHODS:Original studies on simple and extended cholecystectomy for T1a or T1b GB cancer were searched from MEDLINE(PubMed) ,Cochrane Library,EMBase,and CancerLit using the search terms of GB,cancer/carcinoma/tumor/neoplasm. RESULTS:Twenty-nine out of the 2312 potentially relevant publications met the eligibility criteria.Of the 1266 patients with GB cancer included in the publications,706(55.8%) and 560(44.2%) had T1a and T1b GB cancer,respectively.Simple cholecystectomy for T1a and T1b GB cancer was performed in 590(83.6%) and 375(67.0%) patients,respectively(P<0.01) .In most series,the treatment of choice was simple cholecystectomy for T1a GB cancer patients with a 5-year survival rate of 100%.Lymph node metastasis was detected in 10.9% of the T1b GB cancer patients and in 1.8%of the T1a GB cancer patients,respectively(P<0.01) .Eight patients(1.1%) with T1a GB cancer and 52 patients(9.3%) with T1b GB cancer died of recurrent GB cancer(P<0.01) . CONCLUSION:Simple cholecystectomy represents the adequate treatment of T1a GB cancer.There is no definite evidence that extended cholecystectomy is advantageous over simple cholecystectomy for T1b GB cancer.Seung Eun Lee Jin-Young Jang Chang-Sup Lim Mee Joo Kang Sun-Whe Kim 2011World Journal of Gastroenterology2011,17,2:69

10Hepatolithiasis and intrahepatic cholangiocarcinoma: A review显示文摘Although the incidence of hepatolithiasis is decreasing as the pattern of gallstone disease changes in Asia, the prevalence of hepatolithiasis is persistently high, especially in Far Eastern countries. Hepatolithiasis is an established risk factor for cholangiocarcinoma(CCA), and chronic proliferative inflammation may be involved in biliary carcinogenesis and in inducing the upregulation of cell-proliferating factors. With the use of advanced imaging modalities, there has been much improvement in the management of hepatolithiasis and the diagnosis of hepatolithiasis-associated CCA(HLCCA). However, there are many problems in managing the strictures in hepatolithiasis and differentiating them from infiltrating types of CCA. Surgical resection is recommended in cases of single lobe hepatolithiasis with atrophy, uncontrolled stricture, symptom duration of more than 10 years, and long history of biliaryenteric anastomosis. Even after resection, patients should be followed with caution for development of HL-CCA, because HL-CCA is an independent prognostic factor for survival. It is not yet clear whether hepatic resection can reduce the occurrence of subsequent HL-CCA. Furthermore, there are no consistent findings regarding prediction of subsequent HL-CCA in patients with hepatolithiasis. In the management of hepatolithiasis, important factors are the reduction of recurrence of cholangitis and suspicion of unrecognized HL-CCA.Hyo Jung Kim Jae Seon Kim Moon Kyung Joo Beom Jae Lee Ji Hoon Kim Jong Eun Yeon Jong-Jae Park Kwan Soo Byun Young-Tae Bak 2015World Journal of Gastroenterology2015,21,48:63
11Clinical epidemiology and disease burden of nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) is defined as the presence of hepatic fat accumulation after the exclusion of other causes of hepatic steatosis, including other causes of liver disease, excessive alcohol consumption, and other conditions that may lead to hepatic steatosis. NAFLD encompasses a broad clinical spectrum ranging from nonalcoholic fatty liver to nonalcoholic steatohepatitis(NASH), advanced fibrosis, cirrhosis, and finally hepatocellular carcinoma(HCC). NAFLD is the most common liver disease in the world and NASH may soon become the most common indication for liver transplantation. Ongoing persistence of obesity with increasing rate of diabetes will increase the prevalence of NAFLD, and as this population ages, many will develop cirrhosis and end-stage liver disease. There has been a general increase in the prevalence of NAFLD, with Asia leading the rise, yet the United States is following closely behind with a rising prevalence from 15% in 2005 to 25% within 5 years. NAFLD is commonly associated with metabolic comorbidities, including obesity, type Ⅱ diabetes, dyslipidemia, and metabolic syndrome. Our understanding of the pathophysiology of NAFLD is constantly evolving. Based on NAFLD subtypes, it has the potential to progress into advanced fibrosis, end-stage liver disease and HCC. The increasing prevalence of NAFLD with advanced fibrosis, is concerning because patients appear toexperience higher liver-related and non-liver-related mortality than the general population. The increased morbidity and mortality, healthcare costs and declining health related quality of life associated with NAFLD makes it a formidable disease, and one that requires more in-depth analysis.Brandon J Perumpail Muhammad Ali Khan Eric R Yoo George Cholankeril Donghee Kim Aijaz Ahmed 2017World Journal of Gastroenterology2017,23,47:70
12Factors related to lymph node metastasis and surgical strategy used to treat early gastric carcinoma显示文摘AIM:The prognosis of early gastric carcinoma (EGC) is generally excellent after surgery. The presence or absence of lymph node metastasis in EGC is an important prognostic factor. The survival and recurrence rates of node-negative EGC are much better than those of node-positive EGC. This study examined the factors related to lymph node metastasis in EGC to determine the appropriate treatment for EGC.METHODS: We investigated 748 patients with EGC who underwent surgery between January 1985 and December 1999 at the Division of Gastroenterologic Surgery, Department of Surgery, Chonnam National University Hospital. Several clinicopathologic factors were investigated to analyze their relationship to lymph node metastasis: age, sex, tumor location, tumor size, gross type, histologic type, depth of invasion, extent of lymph node dissection, type of operation,and DNA ploidy.RESULTS:Lymph node metastases were found in 75 patients (10.0%). Univariate analysis showed that male sex, tumor size larger than 2.0cm, submucosal invasion of tumor, histologic differentiation, and DNA ploidy pattern were risk factors for regional lymph node metastasis in EGC patients. However, a multivariate analysis showed that three risk factors were associated with lymph node metastasis:large tumor size, undifferentiated histologic type and submucosal invasion. No statistical relationship was found for age, sex, tumor location, gross type, or DNA ploidy in multivariate analysis. The 5-year survival rate was 94.2% for those without lymph node metastasis and 87.3% for those with lymph node metastasis, and the difference was significant (P<0.05).CONCLUSION: In patients with EGC, the survival rate of patients with positive lymph nodes is significantly worse than that of patients with no lymph node metastasis. Therefore,a standard D2 lymphadenectomy should be performed in patients at high risk of lymph node metastasis: large tumor size, undifferentiated histologic type and submucosal invasion.Dong Yi Kim Jae Kyoon Joo Seong Yeob Ryu Young Jin Kim Shin Kon Kim 2004World Journal of Gastroenterology2004,10,5:68
13Comparison of different nutritional assessments in detecting malnutrition among gastric cancer patients显示文摘AIM: To evaluate the prevalence of preoperative and postoperative malnutrition and the relationships between objective and subjective nutritional assessment of gastric cancer patients. METHODS: From October 2005 to July 2006, we studied 80 patients with no evidence of recurrent disease and no loss to follow-up after curative surgery for gastric cancer. In this group, 9 patients underwent total gastrectomy and 71 patients subtotal gastrectomy. At admission, 6 and 12 mo after surgery, the patients were assessed on the subjective global assessment (SGA), nutritional risk screening (NRS-2002), nutritional risk index (NRI) and by anthropometric measurements and laboratory data. Differences between the independent groups were assessed with the Student's t test and oneway analysis of variance. Spearman's rank correlation coefficients were calculated to evaluate the association between the scores and variables. RESULTS: The prevalence of malnutrition at admissionwas 31% by SGA and 43% by NRS-2002. At admission, the anthropometric data were lower in the malnourished groups defined by the SGA and NRS-2002 assessments, but did not differ between the groups using the NRI assessment. Body weight (BW), body mass index (BMI), triceps skin fold and midarm circumference were significantly reduced, but the total lymphocyte count, albumin, protein, cholesterol and serum iron levels did not decrease during the postoperative period. Six months after surgery, there was a good correlation between the nutritional assessment tools (SGA and NRS-2002) and the other nutritional measurement tools (BW, BMI, and anthropometric measurements). However, 12 mo after surgery, most patients who were assessed as malnourished by SGA and NRS-2002 had returned to their preoperative status, although their BW, BMI, and anthropometric measurements still indicated a malnourished status. CONCLUSION: A combination of objective and subjective assessments is needed for the early detection of the nutritional status in case of gastric cancer patients after gastrectomy.Seung Wan Ryu In Ho Kim 2010World Journal of Gastroenterology2010,16,26:57
14Diagnostic value of AFP-L3 and PIVKA-Ⅱin hepatocellular carcinoma according to total-AFP显示文摘AIM:To evaluate diagnostic value ofα-fetoprotein (AFP)-L3 and prothrombin induced by vitamin K absence-Ⅱ(PIVKA-Ⅱ)in hepatocellular carcinoma(HCC). METHODS:One hundred and sixty-eight patients during routine HCC surveillance were included in this study.Of the 168 patients,90(53.6%)had HCC including newly developed HCC(n=82)or recurrent HCC after treatment(n=8).Sera were obtained during their first evaluation for HCC development and at the time of HCC diagnosis before commencing HCC treatment.HCC was diagnosed by histological examination,appropriate imaging characteristics-computed tomography or magnetic resonance imaging.Control sera were collected from 78 patients with benign liver disease(BLD),which were obtained during routine surveillance with a suspicion of HCC.AFP,AFP-L3 and PIVKA-Ⅱwere measured in the same serum by microchip capillary electrophoresis and liquid-phase binding assay on a micro-total analysis system Wako i30 auto analyzer.The performance characteristics of three tests and combined tests for the diagnosis of HCC were obtained using receiver operating characteristic curves in all populations and subgroups with AFP<20 ng/mL. RESULTS:Of 90 HCC patients,38(42.2%)patients had AFP<20 ng/mL,20(22.2%)patients had AFP 20-200 ng/mL and 32(35.6%)patients had AFP>200 ng/mL.Of the 78 BLD patients,74(94.9%)patients had AFP<20 ng/mL.After adjustment for age and HBV infection status,AFP-L3 levels were higher in HCC than in BLD among patients with low AFP levels(<20 ng/mL)(P<0.001).In a total of 168 patients,areas under the curve(AUC)for HCC were 0.879,0.887,0.801 and 0.939 for AFP,AFP-L3,PIVKA-Ⅱand the combined markers,respectively.The combined AUC for three markers showed higher value than the AUCs of individual marker(P<0.05).AFP-L3 had higher AUC value than PIVKA-Ⅱfor HCC detection in entire patients(P =0.043).With combination of AFP-L3(cut-off>5%) and PIVKA-Ⅱ(cut-off>40 AU/L),the sensitivity were 94.4%and specificity were 75.6%in all patients.In 112 patients with low AFP levels(<20 ng/mL),AUCs of AFP-L3,PIVKA-Ⅱand combine AFP-L3 and PIVKA-Ⅱtests were 0.824,0.774 and 0.939,respectively. AFP-L3 with a cut-off value of 5%showed sensitivity of 71.1%and specificity of 83.8%,and PIVKA-Ⅱwith a cut-off value of 40 AU/L had sensitivity of 57.9%and specificity of 95.9%in patients with low AFP levels. The combination of AFP-L3 and PIVKA-Ⅱincreased the sensitivity and specificity up to 92.1%and 79.7%, respectively,in low AFP group.Combined markers detected 81.8%of early stage HCC(Union for Inter-national Cancer Control stageⅠ),86.7%of small sized tumor(<2 cm)and 91.7%of single tumor of HCC in the low AFP group.In multivariate analysis,AFP-L3 was correlated with AFP and tumor size,and PIVKA-Ⅱwas correlated with laboratory tests including serum aspartate aminotransferase,total bilirubin,platelets and albumin levels.PIVKA-Ⅱhad no correlation with AFP,AFP-L3 or tumor characteristics. CONCLUSION:Combined determination of AFP-L3 and PIVKA-Ⅱcould improve the diagnostic value for HCC detection in patients with or without increased AFP levels.Jong Young Choi Seung Won Jung Hee Yeon Kim Myungshin Kim Yonggoo Kim Dong Goo Kim Eun-Jee Oh 2013World Journal of Gastroenterology2013,19,3:55
15中国建立男性包皮环切手术标准化和培训的重要性显示文摘尽管HIV在非洲的大流行仍然是一个严重的问题,而在其他地区,如亚洲和南美洲,HIV感染率也正在迅速上升。国际健康组织已经认识到有必要制定有效的策略来检测和控制全球HIV的传播。研究表明,男性包皮环切能显著降低HIV、人乳头状瘤病毒(HPV)、单纯疱疹病毒2型(HSV-2)和其他性传播疾病(STD)的感染率。虽然男性包皮环切技术有许多,但是没有标准化的手术方案和培训计划。研究表明,男性包皮环切技术的标准化与培训计划的实施可以大大降低并发症发生率。并发症发生率高是实施男性包皮环切服务的一个主要障碍。我们建议,在推广男性包皮环切之前应建立手术标准和培训计划。李石华 吕年青 程跃 彭弋峰 田龙 刘毅东 贲昆龙 徐建春 Richard LEE Howard KIM David C.SOKAL 2009中华男科学杂志2009,15,5:56

17Visceral 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 2003World Journal of Gastroenterology2003,9,12:57
18Diagnostic 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 2015World Journal of Gastroenterology2015,21,13:60
19Learning curve of laparoscopy-assisted distal gastrectomy with systemic lymphadenectomy for early gastric cancer显示文摘AIM: To evaluate the nature of the 'learning curve' for laparoscopy-assisted distal gastrectomy (LADG) with systemic lymphadenectomy for early gastric cancer. METHODS: The data of 90 consecutive patients with early gastric cancer who underwent LADG with systemic lymphadenectomy between April 2003 and November 2004 were reviewed. The 90 patients were divided into 9 sequential groups of 10 cases in each group and the average operative time of these 9 groups were determined. Other learning indicators, such as transfusion requirements, conversion rates to open surgery, postoperative complication, time to first flatus, and postoperative hospital stay, were evaluated. RESULTS: After the first 10 LADGs, the operative time reached its first plateau (230-240 min/operation) and then reached a second plateau (<200 min/operation) for the final 30 cases. Although a significant improvement in the operative time was noted after the first 50 cases, there were no significant differences in transfusion requirements, conversion rates to open surgery, postoperative complications, time to first flatus, or postoperative hospital stay between the groups. CONCLUSION: Based on operative time analysis, this study show that experience of 50 cases of LADG with systemic lymphadenectomy for early gastric cancer is required to achieve optimum proficiency.Min-Chan Kim Ghap-Joong Jung Hyung-Ho Kim 2005World Journal of Gastroenterology2005,11,47:49
