| 1 | Spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein显示文摘Preservation of the spleen at distal pancreatectomy has recently attracted considerable attention.Since our first successful trial,spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein for tumors of the pancreas and chronic pancreatitis has been performed more frequently.The technique for spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein are outlined.The splenic vein is identified behind the pancreas and within the thin connective tissue membrane.The connective tissue membrane is cut longitudinally above the splenic vein.An important issue is to remove the splenic vein from the body of the pancreas toward the spleen,since a different approach may be very difficult.The pancreas is preferably removed from the splenic artery toward the head of the pancreas itself.This procedure is much easier than removing the pancreas from the vein side.One patient had undergone distal gastrectomy for duodenal ulcer,with reconstruction by Billroth Ⅱ tehcnique.If distal pancreatectomy with splenectomy had been performed for the lesion of the distal pancreas at the time,the residual stomach would also have to be resected.The potential damage done to the patient by reconstruction of the gastrointestinal tract in combination with distal pancreatectomy and splenectomy would have been much greater than with distal pancreatectomy only with preservation of the spleen and residual stomach.Benign lesions as well as low-grade malignancy of the body and tail of the pancreas may be a possible indication for this procedure. | Wataru Kimura Toshiyuki Moriya Jinfeng Ma Yukinori Kamio Toshihiro Watanabe Mitsukiro Yano Hiroto Fujimoto Koji Tezuka Ichiro Hirai Akira Fuse | 2007 | World Journal of Gastroenterology2007，13，10： | 24 |
| 2 | Optimal treatment for Siewert type Ⅱ and Ⅲ adenocarcinoma of the esophagogastric junction: A retrospective cohort study with long-term follow-up显示文摘AIM To determine the optimal treatment strategy for Siewert type Ⅱ and?Ⅲ?adenocarcinoma of the esophagogastric junction.METHODS We retrospectively reviewed the medical records of 83 patients with Siewert type?Ⅱ?and?Ⅲ?adenocarcinoma of the esophagogastric junction and calculated both an index of estimated benefit from lymph node dissection for each lymph node(LN) station and a lymph node ratio(LNR: ratio of number of positive lymph nodes to the total number of dissected lymph nodes). We used Cox proportional hazard models to clarify independent poor prognostic factors. The median duration of observation was 73 mo.RESULTS Indices of estimated benefit from LN dissection were as follows, in descending order: lymph nodes(LN) along the lesser curvature, 26.5; right paracardial LN, 22.8; left paracardial LN, 11.6; LN along the left gastric artery, 10.6. The 5-year overall survival(OS) rate was 58%. Cox regression analysis revealed that vigorous venous invasion(v2, v3)(HR = 5.99; 95%CI: 1.71-24.90) and LNR of > 0.16(HR = 4.29, 95%CI: 1.79-10.89) were independent poor prognostic factors for OS.CONCLUSION LN along the lesser curvature, right and left paracardial LN, and LN along the left gastric artery should be dissected in patients with Siewert type?Ⅱ?or?Ⅲ?adenoca rcinoma of the esophagogastric junction. Patients with vigorous venous invasion and LNR of > 0.16 should be treated with aggressive adjuvant chemotherapy to improve survival outcomes. | Kei Hosoda Keishi Yamashita Hiromitsu Moriya Hiroaki Mieno Masahiko Watanabe | 2017 | World Journal of Gastroenterology2017，23，15： | 19 |
| 3 | Pneumatosis cystoides intestinalis following alpha-glucosidase inhibitor treatment:A case report and review of the literature显示文摘A 69-year-old man was diagnosed as having myasthenia gravis (MG) in September 2004,and treated with thymectomy and prednisolone. He was then diagnosed as having steroid-induced diabetes mellitus,and received sulfonylurea (SU) therapy in May 2005. An alpha-glucosidase inhibitor (αGI) was added in March 2006,resulting in good glycemic control. He experienced symptoms of abdominal distention,increased flatus,and constipation in October 2007,and was admitted into our hospital in late November with hematochezia. Plain abdominal radiography revealed small linear radiolucent clusters in the wall of the colon. Computed tomography (CT) showed intramural air in the sigmoid colon. Colonoscopy revealed multiple smooth surfaced hemispherical protrusions in the sigmoid colon. The diagnosis of pneumatosis cystoides intestinalis (PCI) was made on the basis of these findings. As the αGI voglibose was suspected as the cause of this patient's PCI,treatment was conservative,ceasing voglibose,with fasting and fluid supplementation. The patient progressed well,and was discharged 2 wk later. Recently,several reports of PCI associated with αGI therapy have been published,predominantly in Japan where αGIs are commonly used. If the use of αGIs becomes more widespread,we can expect more reports of this condition on a global scale. The possibility of PCI should be considered in diabetic patients complaining of gastrointestinal symptoms,and the gastrointestinal tract should be thoroughly investigated in these patients. | Tatsuhiro Tsujimoto Erika Shioyama Kei Moriya Hideto Kawaratani Yasuyo Shirai Masahisa Toyohara Akira Mitoro Jun-ichi Yamao Hisao Fujii Hiroshi Fukui | 2008 | World Journal of Gastroenterology2008，14，39： | 16 |
| 4 | Helicobacter pylori infection and liver diseases: Epidemiology and insights into pathogenesis显示文摘Both Helicobacter pylori(H. pylori) infection and liver diseases, including nonalcoholic fatty liver disease(NAFLD), viral hepatitis, and hepatocellular carcinoma(HCC), have high prevalences worldwide, and the relationship between H. pylori infection and liver disease has been discussed for many years. Although positive correlations between H. pylori and NAFLD have been identified in some clinical and experimental studies, nega-tive correlations have also been obtained in high-quality clinical studies. Associations between H. pylori and the pathogenesis of chronic viral hepatitis, mainly disease progression with fibrosis, have also been suggested in some clinical studies. Concerning HCC, a possible role for H. pylori in hepatocarcinogenesis has been identified since H. pylori genes have frequently been detected in resected HCC specimens. However, no study hasrevealed the direct involvement of H. pylori in promoting the development of HCC. Although findings regarding the correlations between H. pylori and liver disease pathogenesis have been accumulating, the existing data do not completely lead to an unequivocal conclusion. Further high-quality clinical and experimental analyses are necessary to evaluate the efficacy of H. pylori eradication in ameliorating the histopathological changes observed in each liver disease. | Kazuya Okushin Takeya Tsutsumi Kazuhiko Ikeuchi Akira Kado Kenichiro Enooku Hidetaka Fujinaga Kyoji Moriya Hiroshi Yotsuyanagi Kazuhiko Koike | 2018 | World Journal of Gastroenterology2018，24，32： | 15 |
| 5 | Bacteremia in hemodialysis patients显示文摘Infection is a common complication and is the second leading cause of death in hemodialysis patients. The risk of bacteremia in hemodialysis patients is 26-fold higher than in the general population, and 1/2-3/4 of the causative organisms of bacteremia in hemodialysis patients are Gram-positive bacteria. The ratio of resistant bacteria in hemodialysis patients compared to the general population is unclear. Several reports have indicated that hemodialysis patients have a higher risk of methicillin-resistant Staphylococcus aureus infection. The most common site of infection causing bacteremia is internal prostheses; the use of a hemodialysis catheter is the most important risk factor for bacteremia. Although antibiotic lock of hemodialysis catheters and topical antibiotic ointment can reduce catheter-related blood stream infection(CRBSI), their use should be limited to necessary cases because of the emergence of resistant organisms. Systemic antibiotic administration and catheter removal is recommended for treating CRBSI, although a study indicated the advantages of antibiotic lock and guidewire exchange of catheters over systemic antibiotic therapy. An infection control bundle recommended by the Center for Disease Control and Prevention succeeded in reducing bacteremia in hemodialysis patients with either a catheter or arteriovenous fistula. Appropriate infection control can reduce bacteremia in hemodialysis patients. | Masashi Suzuki Nobuhiko Satoh Motonobu Nakamura Shoko Horita George Seki Kyoji Moriya | 2016 | World Journal of Nephrology2016，5，6： | 14 |
| 6 | Rifaximin ameliorates hepatic encephalopathy and endotoxemia without affecting the gut microbiome diversity显示文摘AIM To determine the efficacy of rifaximin for hepatic encephalopathy(HE) with the linkage of gut microbiome in decompensated cirrhotic patients.METHODS Twenty patients(12 men and 8 women; median age, 66.8 years; range, 46-81 years) with decompensated cirrhosis(Child-pugh score > 7) underwent cognitive neuropsychological testing, endotoxin analysis, and fecal microbiome assessment at baseline and after 4 wk of treatment with rifaximin 400 mg thrice a day. HE was determined by serum ammonia level and number connection test(NCT)-A. Changes in whole blood endotoxin activity(EA) was analyzed by endotoxinactivity assay. Fecal microbiome was assessed by 16 S ribosome RNA(rR NA) gene sequencing.RESULTS Treatment with rifaximin for 4 wk improved hyperammonemia(from 90.6 ± 23.9 μg/d L to 73.1 ± 33.1 μg/dL; P < 0.05) and time required for NCT(from 68.2 ± 17.4 s to 54.9 ± 20.3 s; P < 0.05) in patients who had higher levels at baseline. Endotoxin activity was reduced(from 0.43 ± 0.03 to 0.32 ± 0.09; P < 0.05) in direct correlation with decrease in serum ammonia levels(r = 0.5886, P < 0.05). No statistically significant differences were observed in the diversity estimator(Shannon diversity index) and major components of the gut microbiome between the baseline and after treatment groups(3.948 ± 0.548 at baseline vs 3.980 ± 0.968 after treatment; P = 0.544), but the relative abundances of genus Veillonella and Streptococcus were lowered.CONCLUSION Rifaximin significantly improved cognition and reduced endotoxin activity without significantly affecting the composition of the gut microbiome in patients with decompensated cirrhosis. | Kosuke Kaji Hiroaki Takaya Soichiro Saikawa Masanori Furukawa Shinya Sato Hideto Kawaratani Mitsuteru Kitade Kei Moriya Tadashi Namisaki Takemi Akahane Akira Mitoro Hitoshi Yoshiji | 2017 | World Journal of Gastroenterology2017，23，47： | 14 |
| 7 | Promoted differentiation of cynomolgus monkey ES cells into hepatocyte-like cells by co-culture with mouse fetal liver-derived cells显示文摘AIM: To explore whether a co-culture of cynomolgus monkey embryonic stem (cES) cells with embryonic liver cells could promote their differentiation into hepatocytes. METHODS: Mouse fetal liver-derived cells (MFLCs) were prepared as adherent cells from mouse embryos on embryonic d (ED) 14, after which undifferentiated cES cells were co-cultured with MFLCs. The induction of cES cells along a hepatic lineage was examined in MFLC- assisted differentiation, spontaneous differentiation, and growth factors (GF) and chemicals-induced differentiations (GF-induced differentiation) using retinoic acid, leukemia inhibitory factor (LIF), FGF2, FGF4, hepatocyte growth factor (HGF), oncostatin M (OSM), and dexamethasone. RESULTS: The mRNA expression of α-fetoprotein, albumin (ALB), α-1-antitrypsin, and hepatocyte nuclear factor 4α was observed earlier in the differentiating cES cells co-cultured with MFLCs, as compared to cES cells undergoing spontaneous differentiation and those subjected to GF-induced differentiation. The expression of cytochrome P450 7a1, a possible marker for embryonic endoderm-derived mature hepatocytes, was only observed in cES cells that had differentiated in a co-culture with MFLCs. Further, the disappearance of Oct3/4, a representative marker of an undifferentiated state, was noted in cells co-cultured with MFLCs, but not in those undergoing spontaneous or GF-induced differentiation. Immunocytochemical analysis revealed an increased ratio of ALB-immunopositive cells among cES cells co-cultured with MFLCs, while glycogen storageand urea synthesis were also demonstrated. CONCLUSION: MFLCs showed an ability to induce cES cells to differentiate toward hepatocytes. The co-culture system with MFLCs is a useful method for induction of hepatocyte-like cells from undifferentiated cES cells. | Ko Saito Masahide Yoshikawa Yukiteru Ouji Kei Moriya Mariko Nishiofuku Shigehiko Ueda Noriko Hayashi Shigeaki Ishizaka Hiroshi Fukui | 2006 | World Journal of Gastroenterology2006，12，42： | 11 |
| 8 | Differentiation of embryonic stem cells into insulin-producing cells promoted by Nkx2.2 gene transfer显示文摘AIM: To investigate the ability of a genetically altered embryonic stem (ES) cell line to generate insulin-producing cells in vitro following transfer of the Nkx2.2 gene.METHODS: Hamster Nkx2.2 genes were transferred into mouse ES cells. Parental and Nkx2.2-transfected ES cells were initiated toward differentiation in embryoid body (EB)culture for 5 d and the resulting EBs were transferred to an attached culture system. Dithizone (DTZ), a zincchelating agent known to selectively stain pancreatic beta cells, was used to detect insulin-producing cells.The outgrowths were incubated in DTZ solution (final concentration, 100 μg/mL) for 15 min before being examined microscopically. Gene expression of the endocrine pancreatic markers was also analyzed by RT-PCR. In addition, insulin production was determined immunohistochemically and its secretion was examined using an ELISA.RESULTS: DTZ-stained cellular clusters appeared after approximately 14 d in the culture of Nkx2.2-transfected ES cells (Nkx-ES cells), which was as much as 2 wk earlier, than those in the culture of parental ES cells (wt-ES). The frequency of DTZ-positive cells among total cultured cells on day 28 accounted for approximately 1.0% and 0.1% of the Nkx-ES- and wt-ES-derived EB outgrowths, respectively. The DTZ-positive cellular clusters were found to be immunoreactive to insulin, while the gene expressions of pancreatic-duodenal homeobox 1(PDX1), proinsulin 1 and proinsulin 2 were observed in the cultures that contained DTZ-positive cellular clusters.Insulin secretion was also confirmed by ELISA, whereas glucose-dependent secretion was not demonstrated.CONCLUSION: Nkx2.2-transfected ES cells showed an ability to differentiate into insulin-producing cells. | Akira Shiroi Shigehiko Ueda Yukiteru Ouji Ko Saito Kei Moriya Yuko Sugie Hiroshi Fukui Shigeaki Ishizaka Masahide Yoshikawa | 2005 | World Journal of Gastroenterology2005，11，27： | 9 |
| 9 | Pancreatic schwannoma:Case report and an updated 30-year review of the literature yielding 47 cases显示文摘Pancreatic schwannomas are rare neoplasms.Authors briefly describe a 64-year-old female patient with cystic pancreatic schwannoma mimicking other cystic tumors and review the literature.Databases for PubMed were searched for English-language articles from 1980 to 2010 using a list of keywords,as well as references from review articles.Only 41 articles,including 47 cases,have been reported in the English literature.The mean age was 55.7 years(range 20-87 years),with 45%of patients being male.Mean tumor size was 6.2 cm(range 1-20 cm).Tumor location was the head(40%),head and body(6%),body(21%),body and tail(15%),tail(4%),and uncinate process(13%).Thirty-four percent of patients exhibited solid tumors and 60%of patients exhibited cystic tumors.Treatment included pancreati-coduodenectomy(32%),distal pancreatectomy(21%),enucleation(15%),unresectable(4%),refused opera-tion(2%)and the detail of resection was not specified in 26%of patients.No patients died of disease with a mean follow-up of 15.7 mo(range 3-65 mo),although 5(11%)patients had a malignancy.The tumor size was significantly related to malignant tumor(13.8±6.2 cm for malignancy vs 5.5±4.4 cm for benign,P=0.001) and cystic formation(7.9±5.9 cm for cystic tumorvs 3.9 ±2.4 cm for solid tumor,P=0.005).The preoperative diagnosis of pancreatic schwannoma remains difficult.Cystic pancreatic schwannomas should be considered in the differential diagnosis of cystic neoplasms and pseudocysts.In our case,intraoperative frozen section confirmed the diagnosis of a schwannoma.Simple enucleation may be adequate,if this is possible. | Toshiyuki Moriya Wataru Kimura Ichiro Hirai Akiko Takeshita Koji Tezuka Toshihiro Watanabe Masaomi Mizutani Akira Fuse | 2012 | World Journal of Gastroenterology2012，18，13： | 8 |

| 11 | Serum angiotensin-converting enzyme level for evaluating significant fibrosis in chronic hepatitis B显示文摘AIM To evaluate the diagnostic performance of angiotensinconverting enzyme(ACE)on significant liver fibrosis in patients with chronic hepatitis B(CHB). METHODS In total,100 patients with CHB who underwent liver biopsy in our hospital were enrolled,and 70 patients except for 30 patients with hypertension,fatty liver or habitual alcoholic consumption were analyzed.We compared histological liver fibrosis and serum ACE levels and evaluated the predictive potential to diagnose significant liver fibrosis by comparison with several biochemical marker-based indexes such as the aspartate aminotransferase(AST)-to-platelet ratio index(APRI),the fibrosis index based on four factors(FIB-4),the Mac-2 binding protein glycosylation isomer(M2BPGi)level and the number of platelets(Plt). RESULTS Serum ACE levels showed moderately positive correlation with liver fibrotic stages(R2=0.181).Patients with significant,advanced fibrosis and cirrhosis(F2-4)had significantly higher serum ACE levels than those with early-stage fibrosis and cirrhosis(F0-1).For significant fibrosis(≥F2),the 12.8 U/L cut-off value of ACE showed 91.7%sensitivity and 75.0%specificity.The receiver-operating characteristic(ROC)curves analysis revealed that the area under the curve(AUC)value of ACE was 0.871,which was higher than that of APRI,FIB-4,M2BPGi and Plt. CONCLUSION The serum ACE level could be a novel noninvasive,easy,accurate,and inexpensive marker of significant fibrosis stage in patients with CHB. | Ryuichi Noguchi Kosuke Kaji Tadashi Namisaki Kei Moriya Mitsuteru Kitade Kosuke Takeda Hideto Kawaratani Yasushi Okura Yosuke Aihara Masanori Furukawa Akira Mitoro Hitoshi Yoshiji | 2017 | World Journal of Gastroenterology2017，23，36： | 6 |
| 12 | A novel ascosporogenous yeast species,Zygosaccharomyces siamensis,and the sugar tolerant yeasts associated with raw honey collected in Thailand显示文摘Diversity of yeasts in association with bees and their food sources has been explored during the last decade.In Thailand,there has been no study of yeast identification in honey and bees.Hence,a total of 186 yeast strains were isolated from 37 honey samples of 12 different bee species.On the basis of morphological and physiological characteristics,55 representative strains were chosen and identified by sequence analysis of the 26S rDNA D1/D2 domain and the ITS region.The data were compared with the published sequences and the results showed the occurrence of 19 ascomycetous and 1 basidiomycetous yeast species.Six strains of the new species were isolated.Phylogenetic analysis of the 26S rDNA D1/D2 sequence revealed that they were conspecific and most closely related to Zygosaccharomyces mellis.Based on the ITS sequence,the new species was clustered with the type'and clearly distinguished from the type!.Sequence analysis of combined ITS-26S rDNA D1/D2 showed similar results.The occurrence of these two types,with a divergence of more than 1%in their sequences,and low DNA relatedness among them suggested that members of the typeβcan be regarded as separate species.An analysis of the morphological and physiological characteristics was performed.Ascospore formation was observed on acetate agar and Gorodkowa agar.The new Zygosaccharomyces species differed physiologically from Z.mellis in 4 assimilation tests.This data supports the hypothesis that the new species,Zygosaccharomyces siamensis,is a novel ascosporogenous yeast.The type strain is JCM 16825T(=CBS 12273T)and a description is given here. | Sujinan Saksinchai Motofumi Suzuki Panuwan Chantawannakul Moriya O.hkuma Saisamorn Lumyong | 2012 | Fungal Diversity2012，，1： | 6 |
| 13 | Embryonic stem cells develop into hepatocytes after intrasplenic transplantation in CCl_4-treated mice显示文摘AIM: To transplant undifferentiated embryonic stem (ES) cells into the spleens of carbon tetrachloride (CCl4)-treated mice to determine their ability to differentiate into hepatocytes in the liver. METHODS: CCl4, 0.5 mL/kg body weight, was injected into the peritoneum of C57BL/6 mice twice a week for 5 wk. In group 1 (n = 12), 1 x 105 undifferentiated ES cells (0.1 mL of 1 x 106/mL solution), genetically labeled with GFP, were transplanted into the spleens 1 d after the second injection. Group 2 mice (n = 12) were injected with 0.2 mL of saline twice a week, instead of CCl4, and the same amount of ES cells was transplanted into the spleens. Group 3 mice (n = 6) were treated with CCl4 and injected with 0.1 mL of saline into the spleen, instead of ES cells. Histochemical analyses of the livers were performed on post-transplantation d (PD) 10, 20, and 30. RESULTS: Considerable numbers of GFP-immunopositive cells were found in the periportal regions in group 1 mice (CCl4-treated) on PD 10, however, not in those untreated with CCl4 (group 2). The GFP-positive cells were also immunopositive for albumin (ALB), alpha-1 antitrypsin, cytokeratin 18, and hepatocyte nuclear factor 4 alpha on PD 20. Interestingly, most of the GFP-positive cells were immunopositive for DLK, a hepatoblast marker, on PD 10. Although very few ES-derived cells were demonstrated immunohistologically in the livers of group 1 mice on PD 30, improvements in liver fibrosis were observed. Unexpectedly, liver tumor formation was not observed in any of the mice that received ES cell transplantationduring the experimental period. CONCLUSION: Undifferentiated ES cells developed into hepatocyte-like cells with appropriate integration into tissue, without uncontrolled cell growth. | Kei Moriya Masahide Yoshikawa Ko Saito Yukiteru Ouji Mariko Nishiofuku Noriko Hayashi Shigeaki Ishizaka Hiroshi Fukui | 2007 | World Journal of Gastroenterology2007，13，6： | 5 |
| 14 | Fatal liver failure caused by reactivation of lamivudine-resistant hepatitis B virus:A case report显示文摘We present a case of fetal liver failure caused by the activation of lamivudine-resistant hepatitis B virus (HBV) nine months after lamivudine treatment. A 57-year old man visited our hospital for the treatment of decompensated chronic hepatitis B. Lamivudine was started in December 2001. Subsequently, serum HBV was negative for HBV DNA with seroconversion from HBeAg to anti-HBe and improvement of liver function. However, HBV DNA and HBeAg were again detected in September 2002. He was complicated by breakthrough hepatitis and admitted to our hospital in November for severely impaired liver function. Vidarabine treatment was started and serum HBV DNA and alanine aminotransferase (ALT) decreased transiently. However, after the start of α-interferon treatment, HBV DNA level increased and liver function deteriorated. He died 1 mo after admission. An analysis of amino acid sequences in the polymerase region revealed that rtM204I/V with rtL80I/V occurred at the time of viral breakthrough. After the start of antiviral treatment, rtL180M was detected in addition to rtM204I/V and rtL80I/V, and became predominant in the terminal stage of the disease. HBV clone with a high replication capacity may be produced by antiviral treatment leading to the worsening of liver function. Antiviral therapy for patients with breakthrough hepatitis in advanced liver disease should be carefully performed. | Yuka Suzuki Hiroshi Yotsuyanagi Chiaki Okuse Yoshihiko Nagase Hideaki Takahashi Kyoji Moriya Michihiro Suzuki Kazuhiko Koike Shiro Iino Fumio Itoh | 2007 | World Journal of Gastroenterology2007，13，6： | 4 |
| 15 | Narrow pelvic inlet plane area and obesity as risk factors for anastomotic leakage after intersphincteric resection显示文摘BACKGROUND Intersphincteric resection(ISR)has been increasingly used as the ultimate sphincter-preserving procedure in extremely low rectal cancer.The most critical complication of this technique is anastomotic leakage.The incidence rate of anastomotic leakage after ISR has been reported to range from 5.1%to 20%.AIM To investigate risk factors for anastomotic leakage after ISR based on clinicopathological variables and pelvimetry.METHODS This study was conducted at Department of Colorectal Surgery,Japanese Red Cross Medical Center,Tokyo,Japan,with a total of 117 patients.We enrolled 117 patients with extremely low rectal cancer who underwent laparotomic and laparoscopic ISRs at our hospital.We conducted retrospective univariate and multivariate regression analyses on 33 items to elucidate the risk factors for anastomotic leakage after ISR.Pelvic dimensions were measured using threedimensional reconstruction of computed tomography images.The optimal cutoff value of the pelvic inlet plane area that predicts anastomotic leakage was determined using a receiver operating characteristic(ROC)curve.RESULTS We observed anastomotic leakage in 10(8.5%)of the 117 patients.In the multivariate analysis,we identified high body mass index(odds ratio 1.674;95%confidence interval:1.087-2.58;P=0.019)and smaller pelvic inlet plane area(odds ratio 0.998;95%confidence interval:0.997-0.999;P=0.012)as statistically significant risk factors for anastomotic leakage.According to the receiver operating characteristic curves,the optimal cutoff value of the pelvic inlet plane area was 10074 mm2.Narrow pelvic inlet plane area(≤10074 mm2)predicted anastomotic leakage with a sensitivity of 90%,a specificity of 85.9%,and an accuracy of 86.3%.CONCLUSION Narrow pelvic inlet and obesity were independent risk factors for anastomotic leakage after ISR.Anastomotic leakage after ISR may be predicted from a narrow pelvic inlet plane area(≤10074 mm2). | Akira Toyoshima Toshihiro Nishizawa Eiji Sunami Ryuji Akai Takahiro Amano Akiyoshi Yamashita Shin Sasaki Takeshi Endo Yoshihiro Moriya Osamu Toyoshima | 2020 | World Journal of Gastrointestinal Surgery2020，12，10： | 4 |
| 16 | Dual therapy with zinc acetate and rifaximin prevents from ethanolinduced liver fibrosis by maintaining intestinal barrier integrity显示文摘BACKGROUND Hepatic overload of gut-derived lipopolysaccharide dictates the progression of alcoholic liver disease(ALD)by inducing oxidative stress and activating Kupffer cells and hepatic stellate cells through toll-like receptor 4 signaling.Therefore,targeting the maintenance of intestinal barrier integrity has attracted attention for the treatment of ALD.Zinc acetate and rifaximin,which is a nonabsorbable antibiotic,had been clinically used for patients with cirrhosis,particularly those with hepatic encephalopathy,and had been known to improve intestinal barrier dysfunction.However,only few studies focused on their efficacies in preventing the ALD-related fibrosis development.AIM To investigate the effects of a combined zinc acetate with rifaximin on liver fibrosis in a mouse ALD model.METHODS To induce ALD-related liver fibrosis,female C57BL/6J mice were fed a 2.5%(v/v)ethanol-containing Lieber-DeCarli liquid diet and received intraperitoneal carbon tetrachloride(CCl4)injection twice weekly(1 mL/kg)for 8 wk.Zinc acetate(100 mg/L)and/or rifaximin(100 mg/L)were orally administered during experimental period.Hepatic steatosis,inflammation and fibrosis as well as intestinal barrier function were evaluated by histological and molecular analyses.Moreover,the direct effects of both agents on Caco-2 barrier function were assessed by in vitro assays.RESULTSIn the ethanol plus CCl4-treated mice,combination of zinc acetate and rifaximin attenuated oxidative lipid peroxidation with downregulation of Nox2 and Nox4.This combination significantly inhibited the Kupffer cells expansion and the proinflammatory response with blunted hepatic exposure of lipopolysaccharide and the toll-like receptor 4/nuclear factor kB pathway.Consequently,liver fibrosis and hepatic stellate cells activation were efficiently suppressed with downregulation of Mmp-2,-9,-13,and Timp1.Both agents improved the atrophic changes and permeability in the ileum,with restoration of tight junction proteins(TJPs)by decreasing the expressions of tumor necrosis factorαand myosin light chain kinase.In the in vitro assay,both agents directly reinforced ethanol or lipopolysaccharide-stimulated paracellular permeability and upregulated TJPs in Caco-2 cells.CONCLUSION Dual therapy with zinc acetate and rifaximin may serve as a strategy to prevent ALD-related fibrosis by maintaining intestinal barrier integrity. | Yuki Fujimoto Kosuke Kaji Norihisa Nishimura Masahide Enomoto Koji Murata Soichi Takeda Hiroaki Takaya Hideto Kawaratani Kei Moriya Tadashi Namisaki Takemi Akahane Hitoshi Yoshiji | 2021 | World Journal of Gastroenterology2021，27，48： | 4 |

| 20 | Macroscopic appearance of TypeⅣand giant Type Ⅲ is a high risk for a poor prognosis in pathological stage Ⅱ/Ⅲ advanced gastric cancer with postoperative adjuvant chemotherapy显示文摘AIM To evaluate whether a high risk macroscopic appearance(Type Ⅳ and giant Type Ⅲ) is associated with a dismal prognosis after curative surgery, because its prognostic relevance remains elusive in pathological stage Ⅱ/Ⅲ(p Stage Ⅱ/Ⅲ) gastric cancer.METHODS One hundred and seventy-two advanced gastric cancer(defined as pT2 or beyond) patients with p Stage Ⅱ/Ⅲ who underwent curative surgery plus adjuvant S1 chemotherapy were evaluated, and the prognostic relevance of a high-risk macroscopic appearance was examined. RESULTS Advanced gastric cancers with a high-risk macroscopic appearance were retrospectively identified by preoperative recorded images. A high-risk macroscopic appearance showed a significantly worse relapse free survival(RFS)(35.7%) and overall survival(OS)(34%) than an average risk appearance(P = 0.0003 and P < 0.0001, respectively). A high-risk macroscopic appearance was significantly associated with the 13^(th) Japanese Gastric Cancer Association(JGCA) pT(P = 0.01), but not with the 13^(th) JGCA pN. On univariate analysis for RFS and OS, prognostic factors included 13^(th) JGCA p Stage(P < 0.0001)and other clinicopathological factors including macroscopic appearance. A multivariate Cox proportional hazards model for univariate prognostic factors identified highrisk macroscopic appearance(P = 0.036, HR = 2.29 for RFS and P = 0.021, HR = 2.74 for OS) as an independent prognostic indicator. CONCLUSION A high-risk macroscopic appearance was associated with a poor prognosis, and it could be a prognostic factor independent of 13^(th) JGCA stage in p Stage Ⅱ/Ⅲ advanced gastric cancer. | Keishi Yamashita Akira Ema Kei Hosoda Hiroaki Mieno Hiromitsu Moriya Natsuya Katada Masahiko Watanabe | 2017 | World Journal of Gastrointestinal Oncology2017，9，4： | 2 |
