| 1 | Preoperative, intraoperative and postoperative risk factors for anastomotic leakage after laparoscopic low anterior resection with double stapling technique anastomosis显示文摘Anastomotic leakage(AL) is one of the most devastating complications after rectal cancer surgery. The double stapling technique has greatly facilitated intestinal reconstruction especially for anastomosis after low anterior resection(LAR). Risk factor analyses for AL after open LAR have been widely reported. However, a few studies have analyzed the risk factors for AL after laparoscopic LAR. Laparoscopic rectal surgery provides an excellent operative field in a narrow pelvic space, and enables total mesorectal excision surgery and preservation of the autonomic nervous system with greater precision. However, rectal transection using a laparoscopic linear stapler is relatively difficult compared with open surgery because of the width and limited performance of the linear stapler. Moreover, laparoscopic LAR exhibits a different postoperative course compared with open LAR, which suggests that the risk factors for AL after laparoscopic LAR may also differ from those after open LAR. In this review, we will discuss the risk factors for AL after laparoscopic LAR. | Kenji Kawada Yoshiharu Sakai | 2016 | World Journal of Gastroenterology2016，22，25： | 53 |
| 2 | 枯草芽孢杆菌对石门土鸡生长性能、屠宰性能、血清抗氧化指标和肠道形态的影响显示文摘本试验旨在研究饲粮中添加枯草芽孢杆菌(Bacillus subtilis,BS)对石门土鸡生长性能、屠宰性能、血清抗氧化指标和肠道形态的影响。选取540只55日龄、体重[(0.75±0.02) kg]相近的健康石门土鸡母鸡,随机分成3组,每组6个重复,每个重复30只鸡。对照组饲喂基础饲粮,试验组分别饲喂在基础饲粮的基础上添加300和600 mg/kg BS的试验饲粮。预试期7 d,正试期28 d。结果表明:1) 1~14 d时,与对照组相比,300、600 mg/kg BS组石门土鸡的平均日采食量(ADFI)和平均日增重(ADG)有提高趋势(P>0.05); 15~28 d和1~28 d时,各组间的ADFI、ADG和料重比(F/G)均无显著差异(P> 0.05)。2)与对照组相比,600 mg/kg BS组石门土鸡的屠宰率显著提高(P<0.05),300、600 mg/kg BS组的腹脂率有提高趋势(P>0.05);各组间的半净膛率、全净膛率、胸肌率、腿肌率均无显著差异(P>0.05)。3)与对照组相比,14 d时,300 mg/kg BS组石门土鸡的血清总超氧化物歧化酶(T-SOD)活性显著提高(P <0. 05); 14和28 d时,300、600 mg/kg BS组的血清谷胱甘肽过氧化物酶(GSH-Px)活性极显著提高(P <0.01)。4)与对照组相比,300、600 mg/kg BS组石门土鸡的十二指肠绒毛高度、绒毛宽度、隐窝深度均有提高趋势(P>0.05),300 mg/kg BS组的空肠绒毛宽度显著提高(P<0.05);各组间的回肠绒毛宽度、隐窝深度和绒隐比均无显著差异(P>0.05)。综上,饲粮中添加BS提高了石门土鸡的屠宰性能,增强了机体抗氧化能力,改善了肠道形态。 | 彭豫东 康克浪 曲湘勇 贺长青 陈继发 彭灿阳 YASUHIRO Sakai 周学彬 | 2019 | 动物营养学报2019，31，5： | 34 |
| 3 | Gastric adenocarcinoma of the fundic gland(chief cell-predominant type): A review of endoscopic and clinicopathological features显示文摘Gastric adenocarcinoma of the fundic gland(chief cellpredominant type, GA-FG-CCP) is a rare variant of welldifferentiated adenocarcinoma, and has been proposed to be a novel disease entity. GA-FG-CCP originates from the gastric mucosa of the fundic gland region without chronic gastritis or intestinal metaplasia. The majority of GA-FG-CCPs exhibit either a submucosal tumor-like superficial elevated shape or a flat shape on macroscopic examination. Narrow-band imaging with endoscopic magnification may reveal a regular or an irregular microvascular pattern, depending on the degree of tumor exposure to the mucosal surface. Pathological analysis of GA-FG-CCPs is characterized by a high frequency of submucosal invasion, rare occurrences of lymphatic and venous invasion, and low-grade malignancy. Detection of diffuse positivity for pepsinogen-I by immunohistochemistry is specific for GA-FG-CCP. Careful endoscopic examination and detailed pathological evaluation are essential for early and accurate diagnosis of GA-FG-CCP. Nearly all GA-FG-CCPs are treated by endoscopic resection due to their small tumor size and low risk of recurrence or metastasis. | Masaki Miyazawa Mitsuru Matsuda Masaaki Yano Yasumasa Hara Fumitaka Arihara Yosuke Horita Koichiro Matsuda Akito Sakai Yatsugi Noda | 2016 | World Journal of Gastroenterology2016，22，48： | 26 |
| 4 | Water isotope variations in the snow pack and summer precipitation at July 1 Glacier, Qilian Mountains in northwest China显示文摘This paper presents the stable isotope data of the snow pack and summer precipitation collected at the July 1 Glacier, Qilian Mountains in northwest China and analyses their relationships with meteorologi- cal factors. On an event scale, there is no temperature effect on the δ 18O values in the summer pre- cipitation, whereas the amount effect is shown to be clear. By tracing the moisture transport history and comparing the precipitation with its isotopic composition, it is shown that this amount effect not only reflects the change in moisture trajectory, which is related to the monsoon activities, but is also associated with the cooling degree of vapor in the cloud, the evaporation of falling raindrops and the isotopic exchange between the falling drops and the atmospheric vapor. As very little precipitation occurs in winter, the snow pack profile mainly represents the precipitation in the other three seasons. There are low precipitation δ 18O ratios in summer and high ratios in spring and autumn. The Meteoric Water Line (MLW) for the summer precipitation is δ D = 7.6 δ 18O + 13.3, which is similar to that at Delingha, located in the south rim of the Qilian Mountains. The MWL for the snow pack is δ D = 10.4 δ 18O + 41.4, showing a large slope and intercept. The deuterium excess (d) of the snow pack is positively correlated with δ 18O, indicating that both d and δ 18O decrease from spring to summer and increase from early autumn to early spring. This then results in the high slope and intercept of the MWL. Sea- sonal fluctuations of d in the snow pack indicate the change of moisture source and trajectory. During spring and autumn, the moisture originates from continental recycling or rapid evaporation over rela- tively warm water bodies like Black, Caspian and Aral Seas when the dry westerly air masses pass over them, hence very high d values in precipitation are formed. During summer, the monsoon is responsi- ble for the low d values. This indicates that the monsoon can reach the western part of the Qilian Mountains. | ZHOU ShiQiao NAKAWO Masayoshi SAKAI Akiko MATSUDA Yoshihiro DUAN KeQin PU JianChen | 2007 | Chinese Science Bulletin2007，52，21： | 21 |

| 6 | Comparison between endoscopic sclerotherapy and band ligation for hemostasis of acute variceal bleeding显示文摘AIM:To compare band ligation(BL) with endoscopic sclerotherapy(SCL) in patients admitted to an emergency unit for esophageal variceal rupture. METHODS:A prospective,randomized,single-center study without crossover was conducted.After endoscopic diagnosis of esophageal variceal rupture,patients were randomized into groups for SCL or BL treatment.Sclerotherapy was performed by ethanolamine oleate intravascular injection both above and below the rupture point,with a maximum volume of 20 mL.For BL patients,banding at the rupture point was attempted,followed by ligation of all variceal tissue of the distal esophagus.Primary outcomes for both groups were initial failure of bleeding control(5 d) ,early re-bleeding(5 d to 6 wk),and complications,including mortality.From May 2005 to May 2007,100 patients with variceal bleeding were enrolled in thestudy:50 SCL and 50 BL patients.No differences between groups were observed across gender,age,ChildPugh status,presence of shock at admission,mean hemoglobin levels,and variceal size. RESULTS:No differences were found between groups for bleeding control,early re-bleeding rates,complications,or mortality.After 6 wk,36(80%) SCL and 33(77 %) EBL patients were alive and free of bleeding.A statistically significant association between Child-Pugh status and mortality was found,with 16%mortality in Child A and B patients and 84%mortality in Child C patients(P<0.001) . CONCLUSION:Despite the limited number of patients included,our results suggest that SCL and BL are equally efficient for the control of acute variceal bleeding. | Gustavo Oliveira Luz Fauze Maluf-Filho Sérgio Eiji Matuguma Fábio Yuji Hondo Edson Ide Jeane Martins Melo Spencer Cheng Paulo Sakai | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，5： | 20 |

| 8 | Portal hypertensive colopathy in patients with liver cirrhosis显示文摘AIM: In patients with liver cirrhosis and porlal hypertension, portal hypertensive colopathy is thought to be an important cause of lower gastrointestinal hemorrhage. In this study, we evaluated the prevalence of colonic mucosal changes in patients with liver cirrhosis and its clinical significance. METHODS: We evaluated the colonoscopic findings and liver function of 47 patients with liver cirrhosis over a 6-year period. The main cause of liver cirrhosis was post-viral hepatitis (68%) related to hepatitis B (6%) or C (62%)infection. All patients underwent upper gastrointestinal endoscopy to examine the presence of esophageal varices, cardiac varices, and congestive gastropathy, as well as a full colonoscopy to observe changes in colonic mucosa. Portal hypertensive colopathy was defined endoscopically in patients with vascular ectasia, redness, and blue vein. Vascular ectasia was classified into two types: type 1, solitary vascular ectasia; and type 2, diffuse vascular ectasia.RESULTS: Overall portal hypertensive colopathy was present in 31 patients (66%), including solitary vascular ectasia in 17 patients (36%), diffuse vascular ectasia in 20 patients (42%), redness in 10 patients (21%) and blue vein in 6 patients (12%). As the Child-Pugh class increased in severity, the prevalence of portal hypertensive colopathy rose. Child-Pugh class B and C were significantly associated with portal hypertensive colopathy. Portal hypertensive gastropathy, esophageal varices, ascites and hepatocellular carcinoma were not related to occurrence of portal hypertensive colopathy. Platelet count was significantly associated with portal hypertensive colopathy, but prothrombin time, serum albumin level, total bilirubin level and serum ALT level were not related to occurrence of portal hypertensive colopathy. CONCLUSION: As the Child-Pugh class worsens and platelet count decreases, the prevalence of portal hypertensive colopathy increases in patients with liver cirrhosis. A colonoscopic examination in patients with liver cirrhosis is indicated, especially those with worsening Child-Pugh class and/or decreasing platelet count, to prevent complications such as lower gastrointestinal bleeding. | Keiichi Ito Katsuya Shiraki Takahisa Sakai Hitoshi Yoshimura Takeshi Nakano | 2005 | World Journal of Gastroenterology2005，11，20： | 19 |
| 9 | Multicenter study of endoscopic preoperative biliary drainage for malignant distal biliary obstruction显示文摘AIM: To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal biliary obstruction.METHODS: Multicenter retrospective study was conducted in patients who underwent plastic stent(PS) or nasobiliary catheter(NBC) placement for resectable malignant distal biliary obstruction followed by surgery between January 2010 and March 2012. Procedurerelated adverse events, stent/catheter dysfunction(occlusion or migration of PS/NBC, developmentof cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution(bilirubin level < 3.0 mg/d L) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis.RESULTS: In total, 419 patients were included in the study(PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients(46%), bile duct cancer in 172(41%), gallbladder cancer in three(1%), and ampullary cancer in 50(12%). The median serum total bilirubin was 7.8 mg/d L and 324 patients(77%) had ≥ 3.0 mg/d L. During the median time to surgery of 29 d [interquartile range(IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio(SHR) = 4.76; 95%CI: 2.44-10.0, P < 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method(PS or NBC).CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored. | Naoki Sasahira Tsuyoshi Hamada Osamu Togawa Ryuichi Yamamoto Tomohisa Iwai Kiichi Tamada Yoshiaki Kawaguchi Kenji Shimura Takero Koike Yu Yoshida Kazuya Sugimori Shomei Ryozawa Toshiharu Kakimoto Ko Nishikawa Katsuya Kitamura Tsunao Imamura Masafumi Mizuide Nobuo Toda Iruru Maetani Yuji Sakai Takao Itoi Masatsugu Nagahama Yousuke Nakai Hiroyuki Isayama | 2016 | World Journal of Gastroenterology2016，22，14： | 18 |

| 11 | Effect of phosphorus fluctuation caused by river water dilution in eutrophic lake on competition between blue-green alga Microcystis aeruginosa and diatom Cyclotella sp.显示文摘Tega-numa (Lake Tega) is one of the eutrophic lakes in Japan. For the improvement of water quality in Lake Tega, the North-chiba Water Conveyance Channel was constructed in 2000, which transfer water from Tone River into the lake. After 2000, the dominant species of diatoms, mainly Cyclotella sp., have been replacing blue-green algae, mainly Microcystis aeruginosa in Lake Tega. This transition of dominant species would be due to the dilution, but the detail mechanism has not been understood yet. This study examined the relationship between phosphorus fluctuation caused by river water dilution to Lake Tega and dominance of algal species, M. aeruginosa or Cyclotella sp. based on the single-species and the mixed-species culture experiments. The single-species culture experiment showed that the half-saturation constant and uptake rate of phosphorus were one order lower and seven times higher for M. aeruginosa than those for Cyclotella sp. These findings implied that M. aeruginosa would possess a potential for the growth and survival over Cyclotella sp. in the phosphorus limited condition. The superiority of M. aeruginosa was reflected in the outcome of the mixed-species culture experiment, i.e., dominance of M. aeruginosa, even phosphorus concentration was lowered to 0.01 mg-P/L. Therefore, it could be concluded that the decrease in phosphorus concentration due to the river water dilution to Lake Tega would be interpreted as a minor factor for the transition of dominant species from M. aeruginosa to Cyclotella sp. | Yoshimasa Amano Yusuke Sakai Takumi Sekiya Kimitaka Takeya Kazuo Taki Motoi Machida | 2010 | Journal of Environmental Sciences2010，22，11： | 16 |
| 12 | Deep sedation during gastrointestinal endoscopy: Propofol-fentanyl and midazolam-fentanyl regimens显示文摘AIM: To compare deep sedation with propofol-fentanyl and midazolam-fentanyl regimens during upper gastrointestinal endoscopy. METHODS: After obtaining approval of the research ethics committee and informed consent, 200 patients were evaluated and referred for upper gastrointestinal endoscopy. Patients were randomized to receive propofol-fentanyl or midazolam-fentanyl (n = 100/group).We assessed the level of sedation using the observer's assessment of alertness/sedation (OAA/S) score and bispectral index (BIS). We evaluated patient and physician satisfaction, as well as the recovery time and complication rates. The statistical analysis was performed using SPSS statistical software and included the MannWhitney test, χ 2 test, measurement of analysis of variance, and the κ statistic. RESULTS: The times to induction of sedation, recovery, and discharge were shorter in the propofolfentanyl group than the midazolam-fentanyl group. According to the OAA/S score, deep sedation events occurred in 25% of the propofol-fentanyl group and 11% of the midazolam-fentanyl group (P = 0.014). Additionally, deep sedation events occurred in 19% of the propofol-fentanyl group and 7% of the midazolamfentanyl group according to the BIS scale (P = 0.039). There was good concordance between the OAA/S score and BIS for both groups (κ = 0.71 and κ = 0.63, respectively). Oxygen supplementation was required in 42% of the propofol-fentanyl group and 26% of the midazolam-fentanyl group (P = 0.025). The mean time to recovery was 28.82 and 44.13 min in the propofolfentanyl and midazolam-fentanyl groups, respectively (P < 0.001). There were no severe complications in either group. Although patients were equally satisfied with both drug combinations, physicians were more satisfied with the propofol-fentanyl combination. CONCLUSION: Deep sedation occurred with propofolfentanyl and midazolam-fentanyl, but was more frequent in the former. Recovery was faster in the propofol-fentanyl group. | Marcos Eduardo Lera dos Santos Fauze Maluf-Filho Dalton Marques Chaves Sergio Eiji Matuguma Edson Ide Gustavo de Oliveira Luz Thiago Ferreira de Souza Fernanda C Simoes Pessorrusso Eduardo Guimares Hourneaux de Moura Paulo Sakai | 2013 | World Journal of Gastroenterology2013，19，22： | 16 |
| 13 | Dynamic recrystallization and texture development during hot deformation of magnesium alloy AZ31显示文摘The dynamic recrystallization(DRX) and texture development, taking place during hot deformation of magnesium alloy AZ31 with a strong wire texture, were studied in compression at 673 K (0.73 Tm). Two kinds of samples were machined parallelly to the extruded and transverse directions of Mg alloy rods. New fine grains are evolved at original grain boundaries corrugated at low strains and develop rapidly in the medium range of strain, finally leading to a roughly full evolution of equiaxial fine grains. Kink bands are evolved at grain boundaries corrugated and also frequently in grain interiors at low strains. The boundary misorientations of kink band increase rapidly with increasing strain and approach a saturation value in high strain. The average size of the regions fragmented by kink band is almost the same as that of new grains evolved in high strain. These characteristics of new grain evolution process are not changed by the orientation of the samples, while the flow behaviors clearly depend on it. It is concluded that new grain evolution can be controlled by a deformation-induced continuous reaction, i.e. continuous dynamic recrystallization(DRX). The latter is discussed by comparing with conventional, i.e. discontinuous DRX. | 杨续跃 吉泽升 H. MIURA T. SAKAI | 2009 | 中国有色金属学会会刊:英文版2009，19，1： | 16 |
| 14 | Gastric adenocarcinoma of fundic gland type: Five cases treated with endoscopic resection显示文摘Recently,a new disease entity termed gastric adenocarcinoma of fundic gland type(GA-FG) was proposed.We treated five cases of GA-FG with endoscopic submucosal dissection.All tumors were small and located in the upper third of the stomach.Four tumors were macroscopically identified as 0-IIa and one was identified as 0-Ⅱb.Narrow-band imaging with magnifying endoscopy showed an irregular microvascular pattern in 2 cases and a regular microvascular pattern in the remainder.All tumors arose from the deep layer of the lamina propria mucosae and showed submucosal invasion.Lymphatic invasion was seen only in one case,while no venous invasion was recognized.All tumors were positive for pepsinogen-Ⅰ and MUC6 by immunohistochemistry.None showed p53 overexpression,and the labeling index of Ki-67 was low in all cases.All cases have been free from recurrence or metastasis.Herein,we discussed the clinicopathological features of GA-FG in comparison with past reports. | Masaki Miyazawa Mitsuru Matsuda Masaaki Yano Yasumasa Hara Fumitaka Arihara Yosuke Horita Koichiro Matsuda Akito Sakai Yatsugi Noda | 2015 | World Journal of Gastroenterology2015，21，26： | 16 |

| 19 | Endoscopy vs surgery in the treatment of early gastric cancer:Systematic review显示文摘AIM: To report a systematic review,establishing the available data to an unpublished 2a strength of evidence,better handling clinical practice.METHODS: A systematic review was performed using MEDLINE,EMBASE,Cochrane,LILACS,Scopus and CINAHL databases. Information of the selected studies was extracted on characteristics of trial participants,inclusion and exclusion criteria,interventions(mainly,mucosal resection and submucosal dissection vs surgical approach) and outcomes(adverse events,different survival rates,mortality,recurrence and complete resection rates). To ascertain the validity of eligible studies,the risk of bias was measured using the Newcastle-Ottawa Quality Assessment Scale. The analysis of the absolute risk of the outcomes was performed using the software Rev Man,by computingrisk differences(RD) of dichotomous variables. Data on RD and 95%CIs for each outcome were calculated using the Mantel-Haenszel test and inconsistency was qualified and reported in χ2 and the Higgins method(I2). Sensitivity analysis was performed when heterogeneity was higher than 50%,a subsequent assay was done and other findings were compiled.RESULTS: Eleven retrospective cohort studies were selected. The included records involved 2654 patients with early gastric cancer that filled the absolute or expanded indications for endoscopic resection. Threeyear survival data were available for six studies(n = 1197). There were no risk differences(RD) after endoscopic and surgical treatment(RD = 0.01,95%CI:-0.02-0.05,P = 0.51). Five-year survival data(n = 2310) showed no difference between the two groups(RD = 0.01,95%CI:-0.01-0.03,P = 0.46). Recurrence data were analized in five studies(1331 patients) and there was no difference between the approaches(RD = 0.01,95%CI:-0.00-0.02,P = 0.09). Adverse event data were identified in eight studies(n = 2439). A significant difference was detected(RD =-0.08,95%CI:-0.10--0.05,P < 0.05),demonstrating better results with endoscopy. Mortality data were obtained in four studies(n = 1107). There was no difference between the groups(RD =-0.01,95%CI:-0.02-0.00,P = 0.22).CONCLUSION: Three-,5-year survival,recurrence and mortality are similar for both groups. Considering complication,endoscopy is better and,analyzing complete resection data,it is worse than surgery. | André Kondo Eduardo Guimaraes Hourneaux de Moura Wanderley Marques Bernardo Osmar Kenji Yagi Diogo Turiani Hourneaux de Moura Eduardo Turiani Hourneaux de Moura José Gon?alves Pereira Bravo Kendi Yamazaki Paulo Sakai | 2015 | World Journal of Gastroenterology2015，21，46： | 12 |
| 20 | Clinical usefulness and current problems of pancreatic duct stenting for preventing post-ERCP pancreatitis显示文摘Endoscopic retrograde cholangiopancreatography(ERCP) is an endoscopic procedure with high frequency of accidental symptoms, and particularly some patients who develop and aggravate pancreatitis due to the procedure may need treatment of surgery or die. Various attempts were performed so far to prevent post-ERCP pancreatitis, however, it is impossible to completely prevent pancreatitis at this time because there are various factors for occurrence of post-ERCP pancreatitis.One of the most frequent causes of post-ERCP pancreatitis is considered to be congestion of pancreatic juice associated with duodenal papilledema after examination or treatment. Recently it is often reported that use of a pancreatic duct stent may prevent occurrence of pancreatitis which occurs because of an increased inner pressure of the pancreatic duct caused by congestion of pancreatic juice associated with duodenal papilledema. However, there are some patients who develop pancreatitis even if treated with the pancreatic duct stent, thus further clarification of the pathology and advancement of the prophylactic method will be needed. | Yuji Sakai Toshio Tsuyuguchi Osamu Yokosuka | 2014 | World Journal of Clinical Cases2014，2，9： | 11 |
