| 1 | Helicobacter pylori infection in subjects negative for high titer serum antibody显示文摘AIM To investigate the clinicopathological features of the patients testing negative for high titer serum antiHelicobacter pylori(H. pylori) antibody.METHODS The antibody titers were measured using antigens derived from Japanese individuals. ^(13)C-urea breath test-positive individuals were defined as having H. pylori infection. We investigated the demographic characteristics, laboratory data, endoscopic findings including Kyoto classification of gastritis, and histology in negative-high titer patients without H. pylori eradication therapy. Kyoto classification consisted of scores for gastric atrophy, intestinal metaplasia, enlarged folds, nodularity, and redness.RESULTS Of the 136 subjects enrolled, 23(17%) had H. pylori infection. Kyoto classification had an excellent area under the receiver operating characteristics curve(0.886, 95% confidence interval: 0.803-0.968, P = 3.7 × 10^(-20)) for predicting H. pylori infection with a cutoff value of 2. Further, Kyoto classification, H. pylori density, and neutrophil activity had high accuracies(89.7%, 96.3%, and 94.1%, respectively). Kyoto classification was independent of the demographic and laboratory parameters in multivariate analysis.CONCLUSION Endoscopic Kyoto classification of gastritis is a useful predictor of H. pylori infection in negative-high titer antibody patients. | Osamu Toyoshima Toshihiro Nishizawa Masahide Arita Yosuke Kataoka Kosuke Sakitani Shuntaro Yoshida Hiroharu Yamashita Keisuke Hata Hidenobu Watanabe Hidekazu Suzuki | 2018 | World Journal of Gastroenterology2018，24，13： | 9 |
| 2 | Serum anti-Helicobacter pylori antibody titer and its association with gastric nodularity,atrophy,and age:A cross-sectional study显示文摘AIM To clarify the role of serum anti-Helicobacter pylori(H. pylori) antibody titers in gastric cancer.METHODS In this cross-sectional study, the effect of patients' baseline characteristics and endoscopic findings on their serum antibody titers were assessed. We evaluated consecutive patients who underwent esophagogastroduodenoscopy and their first evaluation for H. pylori infection using a serum antibody test. We excluded patients with a history of eradication therapy. The participants were divided into four groups according to their E-plate serum antibody titer. Patients with serum antibody titers < 3, 3-9.9, 10-49.9, and ≥ 50 U/m L were classified into groups A, B, C, and D, respectively. RESULTS In total, 874 participants were analyzed with 70%, 16%, 8.7%, and 5.1% of them in the groups A, B, C, and D, respectively. Patients in group C were older than patients in groups A and B. Gastric open-type atrophy, intestinal metaplasia, enlarged folds, diffuse redness, and duodenal ulcers were associated with a high titer. Regular arrangements of collecting venules, fundic gland polyps, superficial gastritis, and gastroesophageal reflux disease were related to a low titer. Multivariate analysis revealed that nodularity(P = 0.0094), atrophy(P = 0.0076), and age 40-59 years(vs age ≥ 60 years, P = 0.0090) were correlated with a high serum antibody titer in H. pylori-infected patients. Intestinal metaplasia and atrophy were related to age ≥ 60 years in group C and D.CONCLUSION Serum antibody titer changes with age, reflects gastric mucosal inflammation, and is useful in predicting the risk of gastric cancer. | Osamu Toyoshima Toshihiro Nishizawa Kosuke Sakitani Tadahiro Yamakawa Yoshiyuki Takahashi Nobutake Yamamichi Keisuke Hata Yasuyuki Seto Kazuhiko Koike Hidenobu Watanabe Hidekazu Suzuki | 2018 | World Journal of Gastroenterology2018，24，35： | 9 |
| 3 | Prognostic significance of perioperative tumor marker levels in stage Ⅱ/Ⅲ gastric cancer显示文摘AIM To evaluate the prognostic significance of perioperative carcinoembryonic antigen(CEA) and carbohydrate antigen 19-9(CA19-9) levels in stage Ⅱ/Ⅲ gastric cancer.METHODS From a multi-institutional retrospective database compiled by integrating clinical data from nine institutions, data of 998 patients who underwent curative resection for stage Ⅱ/Ⅲ gastric cancer between 2010 and 2014 were retrieved and analyzed. The prognostic impact of the preoperative and postoperative levels and chronological changes in CEA, CA19-9 and their combination were evaluated. To test whether postoperative adjuvant chemotherapy alters the prognostic impact of perioperative CEA and CA19-9 levels, the hazard ratios for mortality were compared between patients who underwent surgery alone and patients who underwent surgery followed by adjuvant chemotherapy.RESULTS The prognostic impact of postoperative CEA and CA19-9 was superior to that of the preoperative levels. Multivariable analysis identified high postoperative CEA and CA19-9 levels as independent prognostic factors for overall survival.Disease-free survival rates clearly decreased in a stepwise manner in association with postoperative CEA and CA19-9 levels, and patients with high levels of both markers showed significantly poorer prognosis than other patient groups. When we analyzed perioperative changes in serum CEA and CA19-9 levels, patients with high levels before and after surgery had the worst disease-free survival rates among all patient groups. Patients with normalized CEA levels after surgery had a significantly lower disease-free survival rate than those with normal perioperative levels, whereas patients with normalized CA19-9 levels after surgery had equivalent survival to those with normal perioperative levels. The prognostic impact of high CEA levels was observably smaller in patients who underwent adjuvant chemotherapy than in patients who underwent surgery alone, whereas that of high CA19-9 was greater in patients who underwent adjuvant chemotherapy. High postoperative CEA levels were significantly associated with an increased prevalence of liver, lung and bone recurrences, and high postoperative CA19-9 levels were significantly associated with increased frequencies of lymph node and liver recurrences.CONCLUSION The evaluation of serum CEA and CA 19-9 levels both before and after surgery provides useful information for precise risk stratification after curative gastrectomy. | Yasuhito Suenaga Mitsuro Kanda Seiji Ito Yoshinari Mochizuki Hitoshi Teramoto Kiyoshi Ishigure Toshifumi Murai Takahiro Asada Akiharu Ishiyama Hidenobu Matsushita Chie Tanaka Daisuke Kobayashi Michitaka Fujiwara Kenta Murotani Yasuhiro Kodera | 2019 | World Journal of Gastrointestinal Oncology2019，11，1： | 7 |
| 4 | Clinical outcomes of Clutch Cutter endoscopic submucosal dissection for older patients with early gastric cancer显示文摘AIM To evaluate the clinical outcome of endoscopic submucosal dissection using the Clutch Cutter(ESDCC) in older patients. METHODS We reviewed 232 consecutive patients with early gastric cancer who underwent ESDCC between June 2010 and February 2014 at Aso Iizuka Hospital. We divided patients into two groups according to age: Older patients(> 80 years, n = 64) and non-older patients(≤ 80 years, n = 168). We retrospectively compared the prevalence rates of pre-existing comorbidities, anticoagulant therapy, en bloc resection, mean duration of hospitalization, incidence of ESDCC-related complications, change in performance status(PS) before and after ESDCC, and financial cost of admission. RESULTS The older group comprised 64 patients with a mean age of 84.1 years, and the non-older group comprised 168 patients with a mean age of 69.5 years. Older patients had significantly more pre-existing comorbidities than did non-older patients, specifically heart disease(P < 0.05). The en bloc resection rate in non-older patients was significantly higher than that in older patients(100% vs 95.3%, P = 0.02). There were no significant differences between the older and non-older groups in the incidence of ESDCC-related complications(i.e., postoperative bleeding and perforation) and the post-ESDCC change in PS. There were also no significant differences between the older and non-older groups in the mean duration of hospitalization(11.4 and 10.7 d, respectively) and financial cost of admission(657040 JPY and 574890 JPY, respectively).CONCLUSION ESDCC has a good clinical outcome in older patients. | Yoshihiro Otsuka Kazuya Akahoshi Kayoko Yasunaga Masaru Kubokawa Junya Gibo Shigeki Osada Kayo Tokumaru Kazuaki Miyamoto Takao Sato Yuki Shiratsuchi Masafumi Oya Hidenobu Koga Eikichi Ihara Kazuhiko Nakamura | 2017 | World Journal of Gastrointestinal Oncology2017，9，10： | 4 |

| 6 | Hyperammonemia crisis following parturition in a female patient with ornithine transcarbamylase deficiency显示文摘Ornithine transcarbamylase deficiency(OTCD) is an X-linked disorder,with an estimated prevalence of 1 per 80000 live births.Female patients with OTCD develop metabolic crises that are easily provoked by non-predictable common disorders,such as genetic(private mutations and lyonization) and external factors;however,the outcomes of these conditions may differ.We resuscitated a female patient with OTCD from hyperammonemic crisis after she gave birth.Hyperammonemia after parturition in a female patient with OTCD can be fatal,and this type of hyperammonemia persists for an extended period of time.Here,we describe the cause and treatment of hyperammonemia in a female patient with OTCD after parturition.Once hyperammonemia crisis occurs after giving birth,it is difficult to improve the metabolic state.Therefore,it is important to perform an early intervention before hyperammonemia occurs in patients with OTCD or in carriers after parturition. | Jun Kido Tatsuya Kawasaki Hiroshi Mitsubuchi Hidenobu Kamohara Takashi Ohba Shirou Matsumoto Fumio Endo Kimitoshi Nakamura | 2017 | World Journal of Hepatology2017，9，6： | 3 |

| 10 | Endoscopy-based Kyoto classification score of gastritis related to pathological topography of neutrophil activity显示文摘BACKGROUND Endoscopy-based Kyoto classification for gastritis and pathological topographic distribution of neutrophil infiltration are correlated with gastric cancer risk.AIM To investigate the association between Kyoto classification and the topographic distribution of neutrophil activity.METHODS Kyoto classification score,ranging from 0 to 8,consisted of atrophy,intestinal metaplasia,enlarged folds,nodularity,and diffuse redness.Neutrophil activity was scored according to the updated Sydney System using biopsy samples obtained from the greater curvature of the corpus and the antrum.The participants were divided into four categories,inactive stomach,antrumpredominant gastritis,pangastritis,and corpus-predominant gastritis,based on the topographic distribution of neutrophil activity.Effects of sex,age,body mass index,drinking habit,smoking habit,family history of gastric cancer,serum Helicobacter pylori(H.pylori)antibody,and Kyoto score on topography of neutrophil infiltration were analyzed.RESULTS A total of 327 patients(comprising 50.7%women,with an average age of 50.2 years)were enrolled in this study.H.pylori infection rate was 82.9%with a mean Kyoto score of 4.63.The Kyoto score was associated with the topographic distribution of neutrophil activity.Kyoto scores were significantly higher in the order of inactive stomach,antrum-predominant gastritis,pangastritis,and corpuspredominant gastritis(3.05,4.57,5.21,and 5.96,respectively).Each individual score of endoscopic findings(i.e.,atrophy,intestinal metaplasia,enlarged folds,nodularity,and diffuse redness)was correlated with the topographic distribution of neutrophil activity.On multivariate analysis,the Kyoto score,age,and serum H.pylori antibody were independently associated with the topographic distribution of neutrophil activity.CONCLUSION The Kyoto classification score was associated with the topographic distribution of neutrophil activity. | Osamu Toyoshima Toshihiro Nishizawa Shuntaro Yoshida Yoshiki Sakaguchi Yousuke Nakai Hidenobu Watanabe Hidekazu Suzuki Chizu Tanikawa Koichi Matsuda Kazuhiko Koike | 2020 | World Journal of Gastroenterology2020，26，34： | 2 |

| 18 | Importance of considering nutrient loadings from small watersheds to a lake-A case study of the Lake Shinji watershed,Shimane Prefecture,Japan显示文摘Nutrient loadings from upstream watersheds can have significant impacts on the water quality of receiving water bodies.Usually,a major river is selected as the target for water quality studies,and the impact of minor rivers tends to be ignored.It is very important to evaluate whether the impact of small rivers on the downstream water quality is negligible.River water sampling and discharge modeling using SWAT were used to analyze the contribution of small rivers to water quality in a receiving lake.From this analysis,it was determined that the inflowing total nitrogen(TN)and total phosphorus(TP)concentrations from all target rivers exceeded the lake water environmental standards set by the Ministry of the Environment.The contribution of suspended sediment(SS)and TN loads from small rivers did not vary markedly compared with their relative discharge contributions to the lake,at approximately 20%.However,the impact on TP loads to the lake from small rivers was 9.1%higher than their relative flow contributions,accounting for 28.2% of the TP loading.Thus,there is a potential to underestimate the impact of ungauged small rivers if only the major river is selected to evaluate the downstream lake water quality. | Hiroaki Somura Hidenobu Kunii Yasumichi Yone Ikuo Takeda Hirokazu Sato | 2018 | International Journal of Agricultural and Biological Engineering2018，11，5： | 1 |
