1Constructions: A new theoretical approach to language显示文摘A new theoretical approach to language has emerged in the past 10-15 years that allows linguistic observations about form-meaning pairings constructions — to be stated directly. Constructionist approaches aim to account for the full range of facts about language, without assuming that a particular subset of the data is part of a privileged 揷ore? Researchers argue that unusual constructions shed light on more general issues, and serve to illuminate what is required for a complete account of language.Adele E.

2Bacterial infection after liver transplantation显示文摘Infectious complications are major causes of morbidity and mortality after liver transplantation,despite recent advances in the transplant field.Bacteria,fungi,viruses and parasites can cause infection before and after transplantation.Among them,bacterial infections are predominant during the first two months posttransplantation and affect patient and graft survival.They might cause surgical site infections,including deep intra-abdominal infections,bacteremia,pneumonia,catheter-related infections and urinary tract infections.The risk factors for bacterial infections differ between the periods after transplant,and between centers.Recently,the emergence of multi-drug resistant bacteria is great concern in liver transplant(LT)patients.The instructive data about effects of infections with extended-spectrum beta lactamase producing bacteria,carbapenem-resistant gram-negative bacteria,and glycopeptide-resistant gram-positive bacteria were reported on a center-by-center basis.To prevent posttransplant bacterial infections,proper strategies need to be established based upon center-specific data and evidence from well-controlled studies.This article reviewed the recent epidemiological data,risk factors for each type of infections and important clinical issues in bacterial infection after LT.Sang Il Kim 2014World Journal of Gastroenterology2014,20,20:38
3Treatment of hepatocellular carcinoma with portal venous tumor thrombosis: A comprehensive review显示文摘The natural history of hepatocellular carcinoma(HCC)with portal vein tumor thrombosis(PVTT)is dismal(approximately 2-4 mo),and PVTT is reportedly found in 10%-40%of HCC patients at diagnosis.According to the Barcelona Clinic Liver Cancer(BCLC)Staging System(which is the most widely adopted HCC management guideline),sorafenib is the standard of care for advanced HCC(i.e.,BCLC stage C)and the presence of PVTT is included in this category.However,sorafenib treatment only marginally prolongs patient survival and,notably,its therapeutic efficacy is reduced in patients with PVTT.In this context,there have been diverse efforts to develop alternatives to current standard systemic chemotherapies or combination treatment options.To date,many studies on transarterial chemoembolization,3-dimensional conformal radiotherapy,hepatic arterial chemotherapy,and transarterial radioembolization report better overall survival than sorafenib therapy alone,but their outcomes need to be verified in future prospective,randomized controlled studies in order to be incorporated into current treatment guidelines.Additionally,combination strategies have been applied to treat HCC patients with PVTT,with the hope that the possible synergistic actions among different treatment modalities would provide promising results.This narrative review describes the current status of the management options for HCC with PVTT,with a focus on overall survival.Kichang Han Jin Hyoung Kim Gi-Young Ko Dong Il Gwon Kyu-Bo Sung 2016World Journal of Gastroenterology2016,22,1:29
4Limited endoscopic sphincterotomy plus large balloon dilation for choledocholithiasis with periampullary diverticula显示文摘AIM: To investigate the effectiveness and safety of limited endoscopic sphincterotomy (EST) plus large balloon dilation (LBD) for removing choledocholithiasis in patients with periampullary diverticula (PAD). METHODS: A total of 139 patients with common bile duct (CBD) stones were treated with LBD (10-20 mm balloon diameter) after limited EST. Of this total, 73 patients had PAD and 66 patients did not have PAD (controls). The results of stone removal and complications were retrospectively evaluated. RESULTS: There were no significant differences between the PAD and the control groups in overall successful stone removal (94.5% vs 93.9%), stone removal in first session (69.9% vs 81.8%), mechanical lithotripsy (12.3% vs 13.6%), and complications (11.0% vs 7.6%). Clinical outcomes were also similar between the types of PAD, but the rate of stone removal in first session and the number of sessions were significantly lower and more frequent, respectively, in type B PAD (papilla located near the diverticulum) than controls [23/38 (60.5%) vs 54/66 (81.8%), P = 0.021; and 1 (1-2) vs 1 (1-3), P = 0.037, respectively] and the frequency of pancreatitis was significantly higher in type A PAD (papilla located inside or in the margin of the diverticulum) than in controls (16.1% vs 3.0%, P = 0.047). CONCLUSION: Limited EST plus LBD was an effective and safe procedure for removing choledocholithiasis in patients with PAD. However, some types of PAD should be managed with caution.Hyung Wook Kim Dae Hwan Kang Cheol Woong Choi Jong Hwan Park Jin Ho Lee Min Dae Kim Il Doo Kim Ki Tae Yoon Mong Cho Ung Bae Jeon Suk Kim Chang Won Kim Jun Woo Lee 2010World Journal of Gastroenterology2010,16,34:26
5Survival outcome of patients with spontaneously ruptured hepatocellular carcinoma treated surgically or by transarterial embolization显示文摘AIM: To evaluate clinical outcomes of patients that underwent surgery, transarterial embolization (TAE), or supportive care for spontaneously ruptured hepatocellular carcinoma (HCC). METHODS: A consecutive 54 patients who diagnosed as spontaneously ruptured HCC at our institution between 2003 and 2012 were retrospectively enrolled. HCC was diagnosed based on the diagnostic guidelines issued by the 2005 American Association for the Study of Liver Diseases. HCC rupture was defined as disruption of the peritumoral liver capsule with enhanced fluid collection in the perihepatic area adjacent to the HCC by dynamic liver computed tomography, and when abdominal paracentesis showed an ascitic red blood cell count of > 50000 mm 3 /mL in bloody fluid. RESULTS: Of the 54 patients, 6 (11.1%) underwent surgery, 25 (46.3%) TAE, and 23 (42.6%) supportive care. The 2-, 4and 6-mo cumulative survival rates at 2, 4 and 6 mo were significantly higher in the surgery (60%, 60% and 60%) or TAE (36%, 20% and 20%) groups than in the supportive care group (8.7%, 0% and 0%), respectively (each, P < 0.01), and tended to be higher in the surgical group than in the TAE group. Multivariate analysis showed that serum bilirubin (HR = 1.09, P < 0.01), creatinine (HR = 1.46, P = 0.04), and vasopressor requirement (HR = 2.37, P = 0.02) were significantly associated with post-treatment mortality, whereas surgery (HR = 0.41, P < 0.01), and TAE (HR = 0.13, P = 0.01) were inversely associated with posttreatment mortality. CONCLUSION: Post-treatment survival after surgery or TAE was found to be better than after supportive care, and surgery tended to provide better survival benefit than TAE.Young-Joo Jin Jin-Woo Lee Seoung-Wook Park Jung Il Lee Don Haeng Lee Young Soo Kim Soon Gu Cho Yong Sun Jeon Kun Young Lee Seung-Ik Ahn 2013World Journal of Gastroenterology2013,19,28:23

7Radiotherapy as valid modality for hepatocellular carcinoma with portal vein tumor thrombosis显示文摘Although the current standard treatment for hepatocellular carcinoma(HCC) with portal vein tumor thrombosis(PVTT) is sorafenib, many previous studies have established the need for a reliable local modality for PVTT control, which is a major cause of liver function deterioration and metastasis. Additionally, there is growing evidence for the prognostic significance of PVTT classification according to the location of tumor thrombosis. Favorable outcomes can be obtained by applying local modalities, including surgery or transarterial chemoembolization, especially in second-order or distal branch PVTT. Rapid control of PVTT could maintain or improve liver function and reduce intrahepatic as well as distant metastasis. Radiotherapy(RT) is one of the main locoregional treatment modalities in oncologic fields, but has rarely been used in HCC because of concerns regarding hepatic toxicity. However, with the development of advanced techniques, RT has been increasingly applied in HCC management. Randomized studies have yet to definitively prove the benefit of RT, but several comparative studies have justified the application of RT in HCC. The value of RT is especially noticeable in HCC with PVTT; several prospective and retrospective studies have reported favorable outcomes, including a 40% to 60% objective response rate and median overall survival of 15 mo to 20 mo in responders. In this review, we evaluate the role of RT as an alternative local modality in HCC with PVTT.Jeong Il Yu Hee Chul Park 2016World Journal of Gastroenterology2016,22,30:20

11Long-term follow up of endoscopic resection for type 3 gastric NET显示文摘AIM:To clarify the short and long-term results and to prove the usefulness of endoscopic resection in type 3gastric neuroendocrine tumors(NETs).METHODS:Of the 119 type 3 gastric NETs diagnosed from January 1996 to September 2011,50 patients treated with endoscopic resection were enrolled in this study.For endoscopic resection,endoscopic mucosal resection(EMR)or endoscopic submucosal dissection(ESD)was used.Therapeutic efficacy,complications,and follow-up results were evaluated retrospectively.RESULTS:EMR was performed in 41 cases and ESD in 9 cases.Pathologically complete resection was performed in 40 cases(80.0%)and incomplete resection specimens were observed in 10 cases(7 vs 3 patients in the EMR vs ESD group,P=0.249).Upon analysis of the incomplete resection group,lateral or vertical margin invasion was found in six cases(14.6%)in the EMR group and in one case in the ESD group(11.1%).Lymphovascular invasions were observed in two cases(22.2%)in the ESD group and in one case(2.4%)in the EMR group(P=0.080).During the follow-up period(43.73;13-60 mo),there was no evidence of tumor recurrence in either the pathologically complete resection group or the incomplete resection group.No recurrence was reported during follow-up.In addition,no mortality was reported in either the complete resection group or the incomplete resection group for the duration of the follow-up period.CONCLUSION:Less than 2 cm sized confined submucosal layer type 3 gastric NET with no evidence of lymphovascular invasion,endoscopic treatment could be considered at initial treatment.Yong Hwan Kwon Seong Woo Jeon Gwang Ha Kim Jin Il Kim Il-Kwun Chung Sam Ryong Jee Heung Up Kim Geom Seog Seo Gwang Ho Baik Kee Don Choi Jeong Seop Moon 2013World Journal of Gastroenterology2013,19,46:14
12Safety 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
13In vivo theranostics with near-infraredemitting carbon dots—highly efficient photothermal therapy based on passive targeting after intravenous administration显示文摘Carbon dots that exhibit near-infrared fluorescence(NIR CDs)are considered emerging nanomaterials for advanced biomedical applications with low toxicity and superior photostability and targeting compared to currently used photoluminescence agents.Despite progress in the synthesis of NIR CDs,there remains a key obstacle to using them as an in vivo theranostic agent.This work demonstrates that the newly developed sulfur and nitrogen codoped NIR CDs are highly efficient in photothermal therapy(PTT)in mouse models(conversion efficiency of 59%)and can be readily visualized by photoluminescence and photoacoustic imaging.The real theranostic potential of NIR CDs is enhanced by their unique biodistribution and targeting.Contrary to all other nanomaterials that have been tested in biomedicine,they are excreted through the body’s renal filtration system.Moreover,after intravenous injection,NIR CDs are accumulated in tumor tissue via passive targeting,without any active species such as antibodies.Due to their accumulation in tumor tissue without the need for intratumor injection,high photothermal conversion,excellent optical and photoacoustic imaging performance,and renal excretion,the developed CDs are suitable for transfer to clinical biomedical practice.Xin Bao Ye Yuan Jingqin Chen Bohan Zhang Di Li Ding Zhou Pengtao Jing Guiying Xu Yingli Wang Kateřina Holá Dezhen Shen Changfeng Wu Liang Song Chengbo Liu Radek Zbořil Songnan Qu 2018Light(Science & Applications)2018,7,1:13
14Clinical outcomes of small cell neuroendocrine carcinoma and adenocarcinoma of the gallbladder显示文摘AIM: To compare the demographics and survival rates between gallbladder adenocarcinoma(GB-adenocarcinoma) and small cell neuroendocrine carcinoma of the gallbladder(GB-NEC-SCC).METHODS: From March 2007 to September 2012,patients who underwent resection of tumor stage T2/T3 GB cancer were enrolled for this study.Fortytwo patients were included in this study,including 38 diagnosed with GB-adenocarcinoma and four diagnosed with GB-NEC-SCC.In the GB-adenocarcinoma group,a radical operation was performed in 28 patients,and ten patients underwent simple cholecystectomy.In the GB-NEC-SCC group,a radical operation was performed in three patients,and one patient underwent simple cholecystectomy.Comparative analysis of the two groups was performed,including clinicopathologic features and survival rates.RESULTS: The median age of the patients was 68 y(range: 35-83 years) and females comprised 26/42 of the patients.GB-adenocarcinoma patients were significantly older than GB-NEC-SCC patients(67.89 ± 11.15 vs 55.75 ± 10.31 years; P = 0.029).The median tumor size in GB-adenocarcinoma patients was 2.56 ± 1.75 cm and 3.98 ± 3.74 cm in GB-NEC-SCC patients; however,there was no significant difference between the two groups.For tumors > 2 cm,T stage(T2 vs T3),lymphovascular invasion,perineural invasion,lymph node metastasis and lymph node ratio showed no significant differences between the two groups.The overall survival rate of the 42 patients at five years was 77.0%.In the GB-adenocarcinoma group,the overall five-year survival rate was 74.8%,and survival in the GB-NEC-SCC group was 100%,which was not significantly different between the two groups.CONCLUSION: The strategy for treating patients with GB-NEC-SCC should be similar to that used for treating GB-adenocarcinoma,including radical cholecystectomy and liver resection.Sung Pil Yun Nari Shin Hyung Il Seo 2015World Journal of Gastroenterology2015,21,1:13
15Management 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
16Role of surgical resection for multiple hepatocellular carcinomas显示文摘AIM:To clarify the role of surgical resection for multiple hepatocellular carcinomas(HCCs)compared to transarterial chemoembolization(TACE)and liver transplantation(LT). METHODS:Among the HCC patients who were managed at Yonsei University Health System between January 2003 and December 2008,160 patients who met the following criteria were retrospectively enrolled:(1) two or three radiologically diagnosed HCCs;(2)no radiologic vascular invasion;(3)Child-Pugh class A;(4) main tumor smaller than 5 cm in diameter;and(5) platelet count greater than 50 000/mm3.Long-term outcomes were compared among the following three treatment modalities:surgical resection or combined radiofrequency ablation(RFA)(n=36),TACE(n=107), and LT(n=17).The survival curves were computed using the Kaplan-Meier method and compared with a log-rank test.To identify the patients who gained a survival benefit from surgical resection,we also investigated prognostic factors for survival following surgical resection.Multivariate analyses of the prognostic factors for survival were performed using the Cox proportional hazard model. RESULTS:The overall survival(OS)rate was significantly higher in the surgical resection group than in the TACE group(48.1%vs 28.9%at 5 years,P<0.005). LT had the best OS rate,which was better than that of the surgical resection group,although the difference was not statistically significant(80.2%vs 48.1%at 5 years,P=0.447).The disease-free survival rates were also significantly higher in the LT group than in the surgical resection group(88.2%vs 11.2%at 5 years, P<0.001).Liver cirrhosis was the only significant prognostic factor for poor OS after surgical resection. Clinical liver cirrhosis rates were 55.6%(20/36)in the resection group and 93.5%(100/107)in the TACE group.There were 19 major and 17 minor resections. En bloc resection was performed in 23 patients,multisite resection was performed in 5 patients,and combined resection with RFA was performed in 8 patients. In the TACE group,only 34 patients(31.8%)were recorded as having complete remission after primary TACE.Seventy-two patients(67.3%)were retreated with repeated TACE combined with other therapies. In patients who underwent surgical resection,the 16 patients who did not have cirrhosis had higher 5-year OS and disease-free survival rates than the 20 patients who had cirrhosis(80.8%vs 25.5%5-year OS rate, P=0.006;22.2%vs 0%5-year disease-free survival rate,P=0.048).Surgical resection in the 20 patients who had cirrhosis did not provide any survival benefit when compared with TACE(25.5%vs 24.7%5-year OS rate,P=0.225).Twenty-nine of the 36 patients who underwent surgical resection experienced recur-rence.Of the patients with cirrhosis,80%(16/20) were within the Milan criteria at the time of recurrence CONCLUSION:Among patients with two or three HCCs, no radiologic vascular invasion,and tumor diameters≤ 5 cm,surgical resection is recommended only in those without cirrhosis.Sung Hoon Choi Gi Hong Choi Seung Up Kim Jun Yong Park Dong Jin Joo Man Ki Ju Myoung Soo Kim Jin Sub Choi Kwang Hyub Han Soon Il Kim 2013World Journal of Gastroenterology2013,19,3:12
17Anti-inflammatory and Antimicrobial Effects of Anthocyanin Extracted from Black Soybean on Chronic Bacterial Prostatitis Rat Model显示文摘Objective: To investigated the anti-inflammatory and antimicrobial effects of anthocyanins extracted from black soybean on the chronic bacterial prostatitis(CBP) rat model.Methods: The SpragueDawley rats were divided into 4 groups,including control,ciprofloxacin,anthocyanins and anthocyanins with ciprofloxacin groups(n=8 in each group).Then,drip infusion of bacterial suspension(Escherichia coli Z17O_2:K_1:H^-) into Sprague-Dawley rats was conducted to induce CBP.In 4 weeks,results of prostate tissue,urine culture,and histological analysis on the prostate were analyzed for each group.Results: The use of ciprofloxacin,anthocyanins,and anthocyanins with ciprofloxacin showed statistically significant decreases in bacterial growth and improvements in the reduction of prostatic inflammation compared with the control group(P<0.05).The anthocyanins with ciprofloxacin group showed a statistically significant decrease in bacterial growth and improvement in prostatic inflammation compared with the ciprofloxacin group(P<0.05).Conclusions: These results suggest that anthocyanins may have anti-inflammatory and antimicrobial effects,as well as a synergistic effect with ciprofloxacin.Therefore,we suggest that the combination of anthocyanins and ciprofloxacin may be effective in treating CBP to obtain a higher rate of treatment success.Byung Il Yoon Woong Jin Bae Yong Sun Choi Su Jin Kim U Syn Ha Sung-Hoo Hong Dong Wan Sohn Sae Woong Kim 2018Chinese Journal of Integrative Medicine2018,24,8:11
18Conventional endoscopic features are not sufficient to differentiate small, early colorectal cancer显示文摘AIM:To evaluate the depth of invasion of small,early colorectal cancers(ECCs)using conventional endoscopic features.METHODS:From January 2005 to September 2011,colonoscopy cohort showed that a total of 72 patients with small colorectal cancers with the size less than 20mm underwent colonoscopy at the Yonsei University College of Medicine,Seoul,South Korea.Among them,8 patients were excluded due to incomplete medical records.Finally,a total of 64 ECCs with submucosa(SM)invasion and size less than 20 mm were included.One hundred fifty-two adenomas with size less than 20 mm were included as controls.Nine endoscopic features,including seven morphological findings(i.e.,loss of lobulation,excavation,demarcated and depressed areas,stalk swelling,fullness,fold convergence,and bleeding ulcers),pit patterns,and non-lifting signs,were evalu-ated retrospectively.All endoscopic features were evaluated by two experienced endoscopists who have each performed over 1000 colonoscopies annually for more than five years without knowledge of the histology.RESULTS:Among the morphological findings,the size of deep submucosal cancers was bigger than that of superficial lesions(16.9 mm vs 12.3 mm,P<0.001).Also,demarcated depressed areas,stalk swelling,and fullness were more common in deep SM cancers than in superficial tumors(demarcated depressed areas:52.0%vs 15.7%,P<0.001;stalk swelling:100%vs4.2%,P<0.001;fullness:25.0%vs 0%,P=0.001).Among deep SM cancers,96%of polyps showed invasive pit patterns,whereas 19.4%of superficial tumors showed invasive pit patterns(P<0.001).A positive non-lifting sign was more common in deep SM cancers(85.0%vs 28.6%,P<0.001).Diagnostic accuracy of invasive morphology,invasive pit patterns,and nonlifting signs for deep SM cancers were 71%,82%,and75%,respectively.CONCLUSION:Conventional endoscopic findings were insufficient to discriminate small,deep SM cancers from superficial SM cancers by white light,standard colonoscopy.Wan Park Bun Kim Soo Jung Park Jae Hee Cheon Tae Il Kim Won Ho Kim Sung Pil Hong 2014World Journal of Gastroenterology2014,20,21:11
19Characterization of smooth muscle, enteric nerve, interstitial cells of Cajal, and fibroblast-like cells in the gastric musculature of patients with diabetes mellitus显示文摘AIM To investigate histologic abnormalities in the gastric smooth muscle of patients with diabetes mellitus(DM).METHODS Full-thickness gastric specimens were obtained from patients undergoing surgery for gastric cancer. H&E stain and Masson's Trichrome stain were performed to assess the degree of fibrosis. Immunohistochemical staining using various antibodies was also performed [antibodies against protein gene product 9.5(PGP9.5), neuronal nitric oxide synthase(n NOS), vasoactive intestinal peptide(VIP), neurokinin-1(NK1) receptor, c-Kit, and platelet-derived growth factor receptor-alpha,(PDGFRα)]. Immunofluorescent staining and evaluation with confocal microscopy were also conducted.RESULTS Twenty-six controls and 35 diabetic patients(21 shortduration patients and 14 long-duration patients) were included. There were no significant differences in basic demographics between the two groups except in mean body mass index(BMI)(higher in the DM group). Proportions of moderate-to-severe intercellular fibrosis in the muscle layer were significantly higher in the DM group than in the control group(P < 0.01). On immunohistochemical staining, c-Kit- and PDGFRα-positive immunoreactivity were significantly decreased in the DM group compared with the control group(P < 0.05). There were no statistically significant differences in PGP9.5, n NOS, VIP, and neurokinin 1 expression. On immunofluorescent staining, cellularity of interstitial cells of Cajal(ICC) was observed to decrease with increasing duration of DM.CONCLUSION Our study suggests that increased intercellular fibrosis, loss of ICC, and loss of fibroblast-like cells are found in the smooth muscle of DM patients. These abnormalities may contribute to changes in gastric motor activity in patients with DM.Kyung Sik Park Kwang Bum Cho Il Seon Hwang Jae Hyung Park Byung Ik Jang Kyeong Ok Kim Sung Woo Jeon Eun Soo Kim Chang Sik Park Joong Goo Kwon 2016World Journal of Gastroenterology2016,22,46:11
20Prognosis of hepatocellular carcinoma expressing cytokeratin 19:Comparison with other liver cancers显示文摘AIM:To investigate whether expressing biliary phenotype predicted poor outcome after the surgical treatment in primary liver cancers. METHODS:Out of 204 patients that underwent liver resection due to hepatocellular carcinoma (HCC), liver specimens of 70 patients with HCC were evaluated for biliary components by cytokeratin (CK) 19 immunostain (CK19 - HCC and CK19 + HCC). CK19 positivity was defined as membranous and/or cytoplasmic expression in ≥ 5% of tumor cells with moderate or strong intensity. Patients with other primary liver cancers, such as com- bined HCC and cholangiocarcinoma (cHCC-CC), intrahe- patic cholangiocarcinoma (ICC) who received curative liver resection, were also included in the study. Clinical characteristics of CK19-HCC and CK19 + HCC patients, including survival outcome after curative liver resection, were compared with that of cHCC-CC and ICC patients. RESULTS: The overall survival (OS) rate of CK19 - HCC(n = 49) after the curative surgical treatment was 90.7%, and 80.4% at 1 and 5 years after the resection. OS rate of CK19 + HCC (n = 21) was 74.3%, 28.9% and OS rate of cHCC-CC (n = 22) was 66.7%, 32.2% at 1 and 5 years after the surgery. For ICC (n = 19), 1 and 5-year-OS rate was 50.2% and 14.3% after the cura-tive resection. The OS rates of CK19 + HCC and cHCC-CC were significantly lower than that of CK19-HCC, but higher than the OS rate of ICC (P = 0.000). There was no statistically significant difference in OS rate between CK19 + HCC and cHCC-CC. The disease free survival (DFS) rate of CK19-HCC was 72.0% and 54.5% at 1 and 3 years after the surgical treatment. DFS rate of CK19 + HCC was 53.3%, 34.3% and DFS rate of cHCC- CC was 51.5%, 39.2% at 1 and 3 years after the resection. For ICC, 1 and 3-year-DFS rate was 28.0% and 14.0% after the curative resection. DFS rate of CK19-HCC was significantly higher than that of ICC (P = 0.017), but marginally higher than DFS rate of either CK19 + HCC or cHCC-CC (P = 0.097, P = 0.089, respec-tively). Predictors of outcome after the surgery of primary liver cancer were pathology of the resected mass, existence of microvascular invasion and accompanying satellite nodule. CONCLUSION: Primary liver cancers with biliary components tended to show poorer surgical outcome. This suggested that immuno-phenotype of liver cancers was as important as their morphological classification.Jung Il Lee Jin-Woo Lee Joon Mee Kim Ja Kyung Kim Hyun Jung Chung Young Soo Kim 2012World Journal of Gastroenterology2012,18,34:10
