2Colonoscopy evaluation after short-term anti-tuberculosis treatment in nonspecific ulcers on the ileocecal area显示文摘AIM: To evaluate the eff icacy of colonoscopy follow-up after short-term anti-tuberculosis treatment in patients with nonspecific ulcers on ileocecal areas being suspicious of tuberculous colitis. METHODS: We prospectively analyzed the colonoscopic fi ndings before and after short term anti- tuberculosis treatment in 18 patients with nonspecifi c ulcers on the ileocecal area and compared them with 7 patients of confi rmed tuberculous colitis by acid-fast bacilli or caseating granuloma on colonic biopsy. RESULTS: Mean duration for short-term follow- up was 107.3 d with combined chemotherapy containing isoniazid, rifampicin, ethambutol and pyrazinamide. Seven patients with tuberculous colitis showed complete healing of active ulcers after short- term medication. After short-term anti-tuberculosis treatment, follow-up colonoscopy findings devided 18 patients with nonspecific ulcers into two groups by ulcer state. One is the 'suspicious tuberculous colitis group' showing healing of ulcers and erosions and another is the 'suspicious inflammatory bowel disease group' showing active ulcers with or without aggravation of the lesion. Finally, all 9 of the 'suspicious tuberculous colitis group' were diagnosed as tuberculous colitis showing no recurrence of ulcers after termination of 9 mo of anti-tuberculosis medication. Patients of the 'suspicious inflammatorybowel disease group' were f inally diagnosed as Crohn's disease or nonspecifi c colonic ulcers during long-term follow up. CONCLUSION: Follow-up colonoscopy shows a healing stage ulcer or scarring change without an active ulcer with just 2 mo to 3 mo of medication in patients with tuberculous colitis. Colonoscopy follow-up after short term anti-tuberculosis trial in patients with nonspecif ic ulcers on the ileocecal area is valuable in making early differential diagnosis of tuberculous colitis.Young Sook Park Dae Won Jun Seong Hwan Kim Han Hyo Lee Yun Ju Jo Moon Hee Song Nam In Kim Jun Seok Lee 2008World Journal of Gastroenterology2008,14,32:14
3Safety 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
4Piglet gut microbial shifts early in life:causes and effects显示文摘The gut microbiome has long been known to play fundamentally important roles in the animal health and the well-being of its host. As such, the establishment and maintenance of a beneficial gut microbiota early in life is crucial in pigs, since early gut colonizers are pivotal in the establishment of permanent microbial community structures affecting the health and growth performance of pigs later in life. Emphasizing this importance of early gut colonizers, it is critical to understand the factors impacting the establishment of the piglet gut microbiome at weaning. Factors include, among others, diet, in-feed antibiotics, probiotics and prebiotic administration. The impact of these factors on establishment of the gut microbiome of piglets at weaning includes effects on piglet gut microbial diversity, structure, and succession. In this review, we thoroughly reviewed the most recent findings on the piglet gut microbiome shifts as influenced by weaning, and how these microbiome changes brought about by various factors that have been shown to affect the development of microbiota in piglets. This review will provide a general overview of recent studies that can help to facilitate the design of new strategies to modulate the gut microbiome in order to enhance gastrointestinal health, growth performance and well-being of piglets.Robin B.Guevarra Jun Hyung Lee Sun Hee Lee Min-Jae Seok Doo Wan Kim Bit Na Kang Timothy J.Johnson Richard E.Isaacson Hyeun Bum Kim 2019Journal of Animal Science and Biotechnology2019,10,3:13
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
6Impact of tumor location on clinical outcomes of gastric endoscopic submucosal dissection显示文摘AIM:To determine whether there is a correlation between the location of the lesion and endoscopic submucosal dissection(ESD)outcome.METHODS:From January 2008 to December 2010,ESD of 1443 gastric tumors was performed.En bloc resection rate,complete resection rate,procedure time and complication rate were analyzed according to the tumor location.RESULTS:The rates of en bloc resection and complete resection were 91%(1318/1443)and 89%(1287/1443),respectively.The post-ESD bleeding rate was 4.3%,and perforation rate was 2.7%.Tumors located in the upper third of the stomach were associated with a longer procedure time and significantly higher rates of incomplete resection,piecemeal resection,and perforation than tumors below the upper third of the stomach.Posterior wall lesions had significantly longer procedure times and higher rates of incomplete resection and piecemeal resection than lesions in other locations.In multivariate analysis,posterior wall lesions and upper third lesions were significantly associated with incomplete resection and perforation,respectively.In post-ESD bleeding analysis,location was not a significant related factor.CONCLUSION:More advanced endoscopic techniques are required during ESD for lesions located in the upper third or posterior wall of the stomach to decrease complications and improve therapeutic outcomes.Ji Young Yoon Choong Nam Shim Sook Hee Chung Wan Park Hyunsoo Chung Hyuk Lee Sung Kwan Shin Sang Kil Lee Yong Chan Lee Jun Chul Park 2014World Journal of Gastroenterology2014,20,26:10
7Pretreated quercetin protects gerbil hippocampal CA1 pyramidal neurons from transient cerebral ischemic injury by increasing the expression of antioxidant enzymes显示文摘Quercetin(QE; 3,5,7,3′,4′-pentahydroxyflavone), a well-known flavonoid, has been shown to prevent against neurodegenerative disorders and ischemic insults. However, few studies are reported regarding the neuroprotective mechanisms of QE after ischemic insults. Therefore, in this study, we investigated the effects of QE on ischemic injury and the expression of antioxidant enzymes in the hippocampal CA1 region of gerbils subjected to 5 minutes of transient cerebral ischemia. QE was pre-treated once daily for 15 days before ischemia. Pretreatment with QE protected hippocampal CA1 pyramidal neurons from ischemic injury, which was confirmed by neuronal nuclear antigen immunohistochemistry and Fluoro-Jade B histofluorescence staining. In addition, pretreatment with QE significantly increased the expression levels of endogenous antioxidant enzymes Cu/Zn superoxide dismutase, Mn superoxide dismutase, catalase and glutathione peroxidase in the hippocampal CA1 pyramidal neurons of animals with ischemic injury. These findings demonstrate that pretreated QE displayed strong neuroprotective effects against transient cerebral ischemia by increasing the expression of antioxidant enzymes.Bai Hui Chen Joon Ha Park Ji Hyeon Ahn Jeong Hwi Cho In Hye Kim Jae Chul Lee Moo-Ho Won Choong-Hyun Lee In Koo Hwang Jong-Dai Kim Il Jun Kang Jun Hwi Cho Bich Na Shin Yang Hee Kim Yun Lyul Lee Seung Min Park 2017Neural Regeneration Research2017,12,2:9
8Peroxisome 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
9Retrospective 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 2015World Journal of Gastroenterology2015,21,6:9
10Mismatched effects of receptor interacting protein kinase-3 on hepatic steatosis and inflammation in nonalcoholic fatty liver disease显示文摘AIM To validate the effects of receptor interacting protein kinase-3(RIP3) deletion in non-alcoholic fatty liver disease(NAFLD) and to clarify the mechanism of action.METHODS Wild-type(WT) and RIP3 knockout(KO) mice werefed normal chow and high fat(HF) diets for 12 wk. The body weight was assessed once weekly. After 12 wk, the liver and serum samples were extracted. The liver tissue expression levels of RIP3, microsomal triglyceride transfer protein, protein disulfide isomerase, apolipoprotein-B, X-box binding protein-1, sterol regulatory element-binding protein-1c, fatty acid synthase, cluster of differentiation-36, diglyceride acyltransferase, peroxisome proliferator-activated receptor alpha, tumor necrosis factor-alpha(TNF-α), and interleukin-6 were assessed. Oleic acid treated primary hepatocytes from WT and RIP3 KO mice were stained with Nile red. The expression of inflammatory cytokines, including chemokine(C-X-C motif) ligand(CXCL) 1, CXCL2, and TNF-α, in monocytes was evaluated.RESULTS RIP3 KO HF diet fed mice showed a significant gain in body weight, and liver weight, liver to body weight ratio, and liver triglycerides were increased in HF diet fed RIP3 KO mice compared to HF diet fed WT mice. RIP3 KO primary hepatocytes also had increased intracellular fat droplets compared to WT primary hepatocytes after oleic acid treatment. RIP3 overexpression decreased hepatic fat content. Quantitative real-time polymerase chain reaction analysis showed that the expression of very-low-density lipoproteins secretion markers(microsomal triglyceride transfer protein, protein disulfide isomerase, and apolipoprotein-B) was significantly suppressed in RIP3 KO mice. The overall NAFLD Activity Score was the same between WT and RIP3 KO mice; however, RIP3 KO mice had increased fatty change and decreased lobular inflammation compared to WT mice. Inflammatory signals(CXCL1/2, TNF-α, and interleukin-6) increased after lipopolysaccharide and pancaspase inhibitor(necroptotic condition) treatment in monocytes. Neutrophil chemokines(CXCL1, and CXCL2) were decreased, and TNF-α was increased after RIP3 inhibitor treatment in monocytes.CONCLUSION RIP3 deletion exacerbates steatosis, and partially inhibits inflammation in the HF diet induced NAFLD model.Waqar Khalid Saeed Dae Won Jun Kiseok Jang Sang Bong Ahn Ju Hee Oh Yeon Ji Chae Jai Sun Lee Hyeon Tae Kang 2018World Journal of Gastroenterology2018,24,48:7
11Durability 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
12Outcome 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
13Asymptomatic 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
14Hepatic arterial infusion chemotherapy in hepatocellular carcinoma with portal vein tumor thrombosis显示文摘AIM: To evaluate the prognostic factors and efficacy of hepatic arterial infusion chemotherapy in hepatocellular carcinoma with portal vein tumor thrombosis. METHODS: Fifty hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) were treated using hepatic arterial infusion chemotherapy (HAIC) via a subcutaneously implanted port. The epirubicin-cisplatin-5-fluorouracil (ECF) chemotherapeutic regimen consisted of 35 mg/m 2 epirubicin on day 1, 60 mg/m 2 cisplatin for 2 h on day 2, and 500 mg/m 2 5-fluorouracil for 5 h on days 1-3. The treatments were repeated every 3 or 4 wk. RESULTS: Three (6%) of the 50 patients achieved a complete response (CR), 13 (26%) showed partial responses (PR), and 22 (44%) had stable disease (SD).The median survival and time to progression were 7 and 2 mo, respectively. After 2 cycles of HAIC, CR was achieved in 1 patient (2%), PR in 10 patients (20%) and SD in 26 patients (52%). Significant pre-treatment prognostic factors were a tumor volume of < 400 cm 3 (P = 0.01) and normal levels of protein induced by vitamin K absence or antagonist (PIVKA)-Ⅱ (P = 0.022). After 2 cycles of treatment, disease control (CR + PR + SD) (P = 0.001), PVTT response (P = 0.003) and α-fetoprotein reduction of over 50% (P = 0.02) were independent factors for survival. Objective response (CR + PR), disease control, PVTT response, and combination therapy during the HAIC were also significant prognostic factors. Adverse events were tolerable and successfully managed. CONCLUSION: HAIC may be an effective treatment modality for advanced HCC with PVTT in patients with tumors < 400 cm 3 and good prognostic factors.Do Seon Song Si Hyun Bae Myeong Jun Song Sung Won Lee Hee Yeon Kim Young Joon Lee Jung Suk Oh Ho Jong Chun Hae Giu Lee Jong Young Choi Seung Kew Yoon 2013World Journal of Gastroenterology2013,19,29:5
15Gastric inverted hyperplastic polyp: A rare cause of iron deficiency anemia显示文摘Gastric inverted hyperplastic polyp(IHP) is a rare gastric polyp characterized by the downward growth of hyperplastic mucosal components into the submucosal layer. Macroscopically, a gastric IHP resembles a subepithelial tumor(SET); as a result, accurately diagnosing gastric IHP is difficult. This issue has clinical significance because gastric IHP can be misdiagnosed as SET or as malignant neoplasm In addition, adenocarcinoma can accompany benign gastric IHP. Although in most cases, gastric IHPs are asymptomatic and are found incidentally, these polyps may cause anemia secondary to chronic bleeding. Here, we report one case involving gastric IHP accompanied by chronic iron deficiency anemia that was successfully managed using endoscopic submucosal dissection.Jin Tak Yun Seung Woo Lee Dong Pil Kim Seung Hwa Choi Seok-Hwan Kim Jun Kyu Park Sun Hee Jang Yun Jung Park Ye Gyu Sung Hae Jung Sul 2016World Journal of Gastroenterology2016,22,15:5

17New insights into the phylogeny and biogeography of subfamily Orontioideae (Araceae)显示文摘Proto-Araceae,the earliest diverged lineage within the family Araceae,includes two subfamilies,Gymnostachydoideae(one species)and Orontioideae(eight species).Based on an extensive sampling(a total of 198 accessions)of six chloroplast non-coding regions(5799 aligned sites),we assessed phylogenetic relationships among the genera and species within subfamily Orontioideae and estimated the timing of intercontinental disjunct events in the Northern Hemisphere.Overall phylogenetic relationships among the genera were consistent with results from previous studies,but several new important findings were discovered,primarily within Symplocarpus Salisb.ex W.P.C.Barton.First,two major lineages within Symplocarpus were identified:one lineage included S.foetidus(L.)Salisb.ex W.Barton,S.nabekuraensis Otsuka&K.Inoue,and S.renifolius Schott ex Tzvelev(Japan),whereas the other included S.nipponicus Makino,S.egorovi N.S.Pavlova&V.A.Nechaev,and S.renifolius(Korea).Symplocarpus renifolius in Japan was tetraploid and closely related to the tetraploid S.foetidus in eastern North America.Populations of S.renifolius in Korea were confirmed to be diploid(2n=30)and shared the most recent common ancestor with the other diploid species,S.nipponicus.Second,two recently described species,S.nabekuraensis and S.egorovi,were deeply embedded within S.renifolius in Japan and Korea,respectively,and their distinct taxonomic status requires further assessment.Finally,two intercontinental disjunction events in the subfamily,one in Lysichiton Schott between eastern Asia and western North America and the other in Symplocarpus between eastern Asia and eastern North America,were estimated to be between 4.5 and 1.4 million years ago(Pliocene and Pleistocene)and between 1.9 and 0.5 million years ago(Pleistocene),respectively.Joon Seon Lee Seon Hee Kim Sangryong Lee Masayuki Maki Koichi Otsuka Andrey E.Kozhevnikov Zoya V.Kozhevnikova Jun Wen Seung-Chul Kim 2019Journal of Systematics and Evolution2019,57,6:4
18Enhanced efficiency in lead-free bismuth iodide with post treatment based on a hole-conductor-free perovskite solar cell显示文摘Despite the excellent merits of lead perovskite solar cells,their instability and toxicity still present a bottleneck for practical applications.Bismuth perovskite has emerged as a candidate for photovoltaic (PV) applications,because it not only has a low toxicity but is also stable in air.However,the power conversion efficiency (PCE) remains an unsolved problem.We performed band gap tuning experiments to improve the efficiency.The absorption of ABi3I10 structure films was extended within the visible region,and the optical band gap was decreased considerably compared to that for Cs3Bi2I9.Furthermore,we explained the correlation between the structure and the optical properties via a first-principles study.A device employing CsBi3I10 as a photoactive layer exhibits a PCE of 1.51% and an excellent ambient stability over 30 days.Jongmoon Shin Maengsuk Kim Sujeong Jung Chang Su Kim Jucheol Park Aeran Song Kwun-Bum Chung Sung-Ho Jin Jun Hee Lee Myungkwan Song 2018Nano Research2018,11,12:4
19A pilot study of single-use endoscopy in screening acute gastrointestinal bleeding显示文摘AIM:To investigate the feasibility of a single-use endoscopy as an alternative procedure to nasogastric lavage in patients with acute gastrointestinal(GI) bleeding.METHODS:Patients who presented with hematemesis,melena or hematochezia were enrolled in this study.EG scan and conventional esophagogastroduodenoscopy(EGD) were subsequently performed.Active bleeding was defined as blood in the stomach,and inactive bleeding was defined as coffee ground clots and clear fluid in the stomach.The findings were recorded and compared.RESULTS:Between January and March,2011,13 patients that presented with hematemesis(n = 4),melena(n = 6),or bleeding from a previous nasogastric feeding tube(n = 3),were enrolled in this study.In 12 patients with upper GI bleeding,the EG scan device revealed that 7 patients had active bleeding and 5 patients had inactive bleeding,whereas conventional EGD revealed that 8 patients had active bleeding and 4 patients had inactive bleeding.The sensitivity and specificity of the EG scan device was 87.5% and 100% for active bleeding,with conventional EGD serving as a reference.No complication were reported during the EG scan procedures.CONCLUSION:The EG scan is a feasible device for screening acute upper GI bleeding.It may replace nasogastric lavage for the evaluation of acute upper GI bleeding.Jae Hee Cho Hee Man Kim Sangheun Lee Yu Jin Kim Ki Jun Han Hyeon Geun Cho Si Young Song 2013World Journal of Gastroenterology2013,19,1:3
20Effect of external beam radiotherapy on patency of uncovered metallic stents in patients with inoperable bile duct cancer显示文摘BACKGROUND: Although biliary decompression with metallic stenting is the preferred treatment for inoperable bile duct cancer(BDC), maintenance of patency is still unsatisfactory.We tried to assess the effectiveness and safety of external beam radiotherapy(EBRT) for prolonging stent patency in patients having uncovered metallic stents.METHOD: We retrospectively reviewed 50 patients who received endoscopic stenting, of whom 18 received EBRT(RT group) and 32 did not(non-RT group).RESULTS: No difference was found in baseline characteristics between the two groups. Although stent patency was longer in the RT group than that in the non-RT group(140.7±51.3 vs136.4±34.9 days, P=0.94), the difference was not statistically significant. There were a lower rate of stent occlusion(27.8% vs50.0% of patients, P=0.12) and a longer overall survival(420.1 ±73.2 vs 269.1±41.7 days, P=0.11) in the RT group than in the non-RT group, and the difference again was not statistically significant. The development of adverse reactions did not differ(55.6% vs 53.1% of patients, P=0.91). There was no serious adverse reaction in both groups(P=0.99).CONCLUSIONS: EBRT did not significantly improve stent patency in patients with inoperable BDC having uncovered metallic stents. However, EBRT was safe. Future trials withrefined protocols for better efficacy are expected.Jun Kyu Lee Won Kwon Kwack Sang Hyub Lee Jin Hee Jung Jae Hyun Kwon In Woong Han Jin Ho Lee 2014Hepatobiliary & Pancreatic Diseases International2014,13,4:3
