1Clinical utility of the platelet-lymphocyte ratio as a predictor of postoperative complications after radical gastrectomy for clinical T2-4 gastric cancer显示文摘AIM To identify simple and sensitive markers for postoperative complications after gastrectomy, the predictive values were compared among candidate preoperative factors. METHODS Three-hundred and twelve patients with previously untreated clinical T2-4 gastric cancer who underwent a D2 standard gastrectomy(distal gastrectomy or total gastrectomy) were included in the analysis.Correlations between 21 parameters that can be determined by preoperative routine blood tests and clinically relevant postoperative complications(grade Ⅱ or higher according to the Clavien-Dindo classification) were evaluated. The optimal cutoff values and clinical significance of the selected markers were further evaluated by subgroup analyses according to age, body mass index, operative procedure and clinical disease stage.RESULTS Sixty-six patients(21.1%) experienced grade Ⅱ or higher postoperative complications. The plateletlymphocyte ratio(PLR, total lymphocyte count/platelet count × 100) exhibited the highest area under the curve value(0.639) for predicting postoperative complications among the 21 parameters, and the optimal cutoff value was determined to be 0.71(sensitivity = 70%, specificity = 56%). In the univariate analysis, the odds ratio of a low PLR for the occurrence of postoperative complications was 2.94(95%CI: 1.66-5.35, P < 0.001), and a multivariate binomial logistic analysis involving other potential risk factors identified a low PLR as an independent risk factor for postoperative complications(OR = 3.32, 95%CI: 1.82-6.25, P < 0.001). In subgroups classified according to age, body mass index, operative procedure and clinical disease stage, the low PLR group exhibited an increased incidence of postoperative complications. CONCLUSION The preoperative PLR is a simple and useful predictor of complications after curative gastrectomy in patients with clinical T2-4 gastric cancer.Kenichi Inaoka Mitsuro Kanda Hiroaki Uda Yuri Tanaka Chie Tanaka Daisuke Kobayashi Hideki Takami Naoki Iwata Masamichi Hayashi Yukiko Niwa Suguru Yamada Tsutomu Fujii Hiroyuki Sugimoto Kenta Murotani Michitaka Fujiwara Yasuhiro Kodera 2017World Journal of Gastroenterology2017,23,14:13
2Effects of 5-HT2B, 5-HT3 and 5-HT4 receptor antagonists on gastrointestinal motor activity in dogs显示文摘AIM:To study the effects of 5-hydroxytryptamine(5-HT)receptor antagonists on normal colonic motor activity in conscious dogs.METHODS:Colonic motor activity was recorded using a strain gauge force transducer in 5 dogs before and after 5-HT2B,5-HT3 and 5-HT4 receptor antagonist administration.The force transducers were implanted on the serosal surfaces of the gastric antrum,terminal ileum,ileocecal sphincter and colon.Test materials or vehicle alone was administered as an intravenous bolus injection during a quiescent period of the whole colon in the interdigestive state.The effects of these receptor antagonists on normal gastrointestinal motor activity were analyzed.RESULTS:5-HT2B,5-HT3 and 5-HT4 receptor antagonists had no contractile effect on the fasting canine terminal ileum.The 5-HT3 and 5-HT4 receptor antagonists inhibited phaseⅢof the interdigestive motor complex of the antrum and significantly inhibited colonic motor activity.In the proximal colon,the inhibitory effect was dose dependent.Dose dependency,however,was not observed in the distal colon.The 5-HT2B receptor antagonist had no contractile effect on normal colonic motor activity.CONCLUSION:The 5-HT3 and 5-HT4 receptor antagonists inhibited normal colonic motor activity.The5-HT2B receptor antagonist had no contractile effect on normal colonic motor activity.Hiroki Morita Erito Mochiki Nobuyuki Takahashi Kiyoshi Kawamura Akira Watanabe Toshinaga Sutou Atsushi Ogawa Mitsuhiro Yanai Kyoichi Ogata Takaaki Fujii Tetsuro Ohno Souichi Tsutsumi Takayuki Asao Hiroyuki Kuwano 2013World Journal of Gastroenterology2013,19,39:9
3Usefulness of vonoprazan,a potassium ion-competitive acid blocker,for primary eradication of Helicobacter pylori显示文摘AIM To investigate usefulness of triple therapy with vonoprazan,a potassium ion-competitive acid blocker and antibiotics,for Helicobacter pylori(H.pylori) eradication.METHODS The H.pylori eradication rate was examined in 2507 patients(2055 undergoing primary eradication and 452 undergoing secondary eradication,excluding patients with subtotal gastrectomy) at the Japanese Red Cross Kyoto Daiichi Hospital from March 2013 to September 2015.For patients treated from March 2013 to February 2015,a proton pump inhibitor(PPI) was used to reduce acid secretion,while vonoprazan was used after March 2015.The success rates of the 2 regimens(PPI + amoxicillin + clarithromycin/metronidazole,or vonoprazan + amoxicillin + clarithromycin/metronidazole) were compared.RESULTS The success rate of primary H.pylori eradication was significantly higher in the vonoprazan group.When stratified by the underlying disease,a significant increase of the H.pylori eradication rate was observed in patients with chronic gastritis.A significantly lower H.pylori eradication rate was observed in younger patients compared to older patients in the PPI group,but there was no difference according to age in the vonoprazan group.On the otherhand,the success rate of secondary eradication was similar at approximately 90% in both groups.CONCLUSION Vonoprazan is very useful for primary eradication of H.pylori,and may become a first-line acid secretion inhibitor instead of PPIs.Shinya Yamada Takumi Kawakami Yoshikazu Nakatsugawa Takahiro Suzuki Hideki Fujii Naoya Tomatsuri Hideki Nakamura Hideki Sato Yusuke Okuyama Hiroyuki Kimura Norimasa Yoshida 2016World Journal of Gastrointestinal Pharmacology and Therapeutics2016,7,4:8
4The increase in surface CXCR4 expression on lung extravascular neutrophils and its effects on neutrophils during endotoxin-induced lung injury显示文摘Inflammatory stimuli,such as a microbes or lipopolysaccharides,induce a rapid release of neutrophils from the bone marrow and promote neutrophil migration into inflamed sites to promote host defense.However,an excess accumulation and retention of neutrophils in inflamed tissue can cause severe tissue injuries in the later stages of inflammation.Recent studies have reported that both CXCL12 levels in injured lungs and its receptor,CXCR4,on accumulated neutrophils in injured lungs,increased;furthermore,these studies showed that the CXCL12/CXCR4 signaling pathway participated in neutrophil accumulation in the later stages of lipopolysaccharide(LPS)-induced lung injury.However,the mechanisms underlying this increase in surface CXCR4 expression in neutrophils remain unclear.In this study,we found that surface CXCR4 expression increased in extravascular,but not intravascular,neutrophils in the lungs of LPS-induced lung injury model mice.Furthermore,ex vivo studies revealed that CXCL12 acted not only as a chemoattractant,but also as a suppressor of cell death for the lung neutrophils expressing CXCR4.Sulfatide,one of the native ligands for L-selectin,induced the increase of surface CXCR4 expression on isolated circulating neutrophils,suggesting that the activation of L-selectin may be involved in the increase in surface CXCR4.Our findings show that surface CXCR4 levels on neutrophils increase after extravasation into injured lungs,possibly through the activation of L-selectin.The CXCL12/CXCR4 signaling pathway plays an important role in the modulation of neutrophil activity during acute lung injury,not only by promoting chemotaxis but also by suppressing cell death.Mitsuhiro Yamada Hiroshi Kubo Seiichi Kobayashi Kota Ishizawa Mei He Takaya Suzuki Naoya Fujino Hiroyuki Kunishima Masamitsu Hatta Katsushi Nishimaki Tetsuji Aoyagi Kouichi Tokuda Miho Kitagawa Hisakazu Yano Hirokazu Tamamura Nobutaka Fujii Mitsuo Kaku 2011Cellular & Molecular Immunology2011,8,4:6

8Real-world efficacy of daclatasvir and asunaprevir with respect to resistance-associated substitutions显示文摘AIM To investigate daclatasvir(DCV) and asunaprevir(ASV) efficacy in hepatitis C(HCV) patients, with respect to resistance-associated substitutions(RASs).METHODS A total of 392 HCV-infected patients from multiple centers were included in this study. We evaluated their clinical courses and sustained virologic responses(SVR) according to pretreatment factors(gender, age, history of interferon-based regimens, platelet counts, level of viremia, pretreatment NA5A:L31, and Y93 substitutions). We also analyzed the pretreatment and post-treatment major RASs of NS3:D168, NS5A:L31 and Y93 substitutions using a direct-sequencing method in 17 patients who were unable to achieve SVR at 12 wk after treatment completion(SVR12).RESULTS The overall SVR12 rate was 88.3%. Thirty-one patients discontinued treatment before 24 wk because of adverse events, 23 of whom achieved SVR12. There were no significant differences in SVR12 rates with respect to gender, age, history of interferon-based regimens, and platelet counts. The SVR12 rate in patients with viral loads of ≥ 6.0 log IU/m L was significantly lower than those with viral loads of < 6.0 log IU/m L(P < 0.001). The SVR12 rate in patients with Y93 substitution-positive was significantly lower than those with Y93 substitution-negative(P < 0.001). The L31 substitution-positive group showed a lower SVR12 rate than the L31 substitution-negative group, but the difference was not statistically significant. Seventeen patients who did not achieve SVR12 and had available pretreatment and post-treatment sera had additional RASs in NS3:D168, NS5:L31, and Y93 substitution at treatment failure.CONCLUSION Combination of DCV and ASV is associated with a high SVR rate. Baseline RASs should be thoroughly assessed to avoid additional RASs after treatment failure.Hideki Fujii Atsushi Umemura Taichiro Nishikawa Kanji Yamaguchi Michihisa Moriguchi Hideki Nakamura Kohichiroh Yasui Masahito Minami Saiyu Tanaka Hiroki Ishikawa Hiroyuki Kimura Shiro Takami Yasuyuki Nagao Toshihide Shima Yoshito Itoh 2017World Journal of Hepatology2017,9,25:3

13Endoscopic mucosal resection vs endoscopic submucosal dissection for superficial non-ampullary duodenal tumors显示文摘BACKGROUND The selection of endoscopic treatments for superficial non-ampullary duodenal epithelial tumors(SNADETs)is controversial.AIM To compare the efficacy and safety of endoscopic mucosal resection(EMR)and endoscopic submucosal dissection(ESD)for SNADETs.METHODS We retrospectively analyzed the data of patients with SNADETs from a database of endoscopic treatment for SNADETs,which included eight hospitals in Fukuoka,Japan,between April 2001 and October 2017.A total of 142 patients with SNADETs treated with EMR or ESD were analyzed.Propensity score matching was performed to adjust for the differences in the patient characteristics between the two groups.We analyzed the treatment outcomes,including the rates of en bloc/complete resection,procedure time,adverse event rate,hospital stay,and local or metastatic recurrence.RESULTS Twenty-eight pairs of patients were created.The characteristics of patients between the two groups were similar after matching.The EMR group had a significantly shorter procedure time and hospital stay than those of the ESD group[median procedure time(interquartile range):6(3-10.75)min vs 87.5(68.5-136.5)min,P<0.001,hospital stay:8(6-10.75)d vs 11(8.25-14.75)d,P=0.006].Other outcomes were not significantly different between the two groups(en bloc resection rate:82.1%vs 92.9%,P=0.42;complete resection rate:71.4%vs 89.3%,P=0.18;and adverse event rate:3.6%vs 17.9%,P=0.19,local recurrence rate:3.6%vs 0%,P=1;metastatic recurrence rate:0%in both).Only one patient in the ESD group underwent emergency surgery owing to intraoperative perforation.CONCLUSION EMR has significantly shorter procedure time and hospital stay than ESD,and provides acceptable curability and safety compared to ESD.Accordingly,EMR for SNADETs is associated with lower medical costs.Mitsuru Esaki Kazuhiro Haraguchi Kazuya Akahoshi Naru Tomoeda Akira Aso Soichi Itaba Haruei Ogino Yusuke Kitagawa Hiroyuki Fujii Kazuhiko Nakamura Masaru Kubokawa Naohiko Harada Yosuke Minoda Sho Suzuki Eikichi Ihara Yoshihiro Ogawa 2020World Journal of Gastrointestinal Oncology2020,12,8:2

15Late-onset severe biliary bleeding after endoscopic pigtail plastic stent insertion显示文摘Here, we report our experience with a case of severe biliary bleeding due to a hepatic arterial pseudoaneurysm that had developed 1 year after endoscopic biliary plastic stent insertion. The patient, a 78-year-old woman, presented with hematemesis and obstructive jaundice. Ruptured hepatic arterial pseudoaneurysm was diagnosed, which was suspected to have been caused by long-term placement of an endoscopic retrograde biliary drainage(ERBD) stent. This episode of biliary bleeding was successfully treated by transarterial embolization(TAE). Pseudoaneurysm leading to hemobilia is a rare but potentially fatal complication in patients with long-term placement of ERBD. TAE is a minimally invasive procedure that offers effective treatment for biliary bleeding.Muneji Yasuda Hideki Sato Yuki Koyama Tomoki Sakakida Takumi Kawakami Takeshi Nishimura Hideki Fujii Yoshikazu Nakatsugawa Shinya Yamada Naoya Tomatsuri Yusuke Okuyama Hiroyuki Kimura Takaaki Ito Hiroyuki Morishita Norimasa Yoshida 2017World Journal of Gastroenterology2017,23,4:2
