| 3 | Analysis of ABC (D) stratification for screening patients with gastric cancer显示文摘AIM:To evaluate the value of ABC(D) stratification [combination of serum pepsinogen and Helicobacter pylori(H.pylori) antibody]of patients with gastric cancer.METHODS:Ninety-five consecutive patients with gastric cancer were enrolled into the study.The serum pepsinogenⅠ(PGⅠ) /pepsinogenⅡ(PGⅡ) and H.pylori antibody levels were measured.Patients were classified into five groups of ABC(D) stratification according to their serological status.Endoscopic findings of atrophic gastritis and histological differentiation were also analyzed in relation to the ABC(D) stratification.RESULTS:The mean patient age was(67.9±8.9) years.Three patients(3.2%) were classified into group A,7 patients(7.4%) into group A',27 patients(28.4%) into group B,54 patients(56.8%) into group C,and 4patients(4.2%) into group D,respectively.There were only three cases in group A when the patients taking acid proton pump inhibitors and those who had undergone eradication therapy for H.pylori(group A') were excluded.These three cases had mucosal atrophy in the grey zone according to the diagnostic manual of ABC(D) stratification.Histologically,the mean age of the patients with well differentiated adenocarcinoma was significantly higher than that of the patients with poorly differentiated adenocarcinoma(P<0.05) .There were no differences in the pattern of atrophy in the endoscopies between the well differentiated and poorly differentiated groups.CONCLUSION:ABC(D) stratification is a good method for screening patients with gastric cancers.Endoscopy is needed for grey zone cases to check the extent of mucosal atrophy. | Tomohiro Kudo Satoru Kakizaki Naondo Sohara Yasuhiro Onozato Shinichi Okamura Yoshikatsu Inui Masatomo Mori | 2011 | World Journal of Gastroenterology2011,17,43: | 17 |
| 4 | Dietary polyphenols and colorectal cancer risk:The Fukuoka colorectal cancer study显示文摘AIM:To investigate the associations between dietary intake of polyphenols and colorectal cancer. METHODS:The study subjects were derived from the Fukuoka colorectal cancer study, a community-based case-control study. The study subjects were 816 cases of colorectal cancer and 815 community-based controls. The consumption of 148 food items was assessed by a computer-assisted interview. We used the consumption of 97 food items to estimate dietary intakes of total, tea and coffee polyphenols. The Phenol-Explorer database was used for 92 food items. Of the 5 foods which were not listed in the Phenol-Explorer Database, polyphenol contents of 3 foods (sweet potatoes, satoimo and daikon) were based on a Japanese study and 2 foods (soybeans and fried potatoes) were estimated by ORAC-based polyphenol contents in the United States Department of Agriculture Database. Odds ratios (OR) and 95%CI of colorectal cancer risk according to quintile categories of intake were obtained by using logistic regression models with adjustment for age, sex, residential area, parental history of colorectal cancer, smoking, alcohol consumption, body mass index 10 years before, type of job, leisure-time physical activity and dietary intakes of calcium and n-3 polyunsaturated fatty acids.RESULTS:There was no measurable difference in total or tea polyphenol intake between cases and controls, but intake of coffee polyphenols was lower in cases than in controls. The multivariate-adjusted OR of colorectal cancer according to quintile categories of coffee polyphenols (from the first to top quintile) were 1.00 (referent), 0.81 (95%CI:0.60-1.10), 0.65 (95%CI:0.47-0.89), 0.65 (95%CI:0.46-0.89) and 0.82 (95%CI:0.60-1.10), respectively (P trend = 0.07). Similar, but less pronounced, decreases in the OR were also noted for the third and fourth quintiles of total polyphenol intake. Tea polyphenols and non-coffee polyphenols showed no association with colorectal cancer risk. The sitespecific analysis, based on 463 colon cancer cases and 340 rectal cancer cases, showed an inverse association between coffee polyphenols and colon cancer. The multivariate-adjusted OR of colon cancer for the first to top quintiles of coffee polyphenols were 1.00 (referent), 0.92 (95%CI:0.64-1.31), 0.75 (95%CI:0.52-1.08), 0.69 (95%CI:0.47-1.01), and 0.68 (95%CI:0.46-1.00), respectively (P trend = 0.02). Distal colon cancer showed a more evident inverse association with coffee polyphenols than proximal colon cancer. The association between coffee polyphenols and rectal cancer risk was U -shaped, with significant decreases in the OR at the second to fourth quintile categories. There was also a tendency that the OR of colon and rectal cancer decreased in the intermediate categories of total polyphenols. The decrease in the OR in the intermediate categories of total polyphenols was most pronounced for distal colon cancer. Intake of tea polyphenols was not associated with either colon or rectal cancer. The associations of coffee consumption with colorectal, colon and rectal cancers were almost the same as observed for coffee polyphenols. The trend of the association between coffee consumption and colorectal cancer was statistically significant. CONCLUSION:The present findings suggest a decreased risk of colorectal cancer associated with coffee consumption. | Zhen-Jie Wang Keizo Ohnaka Makiko Morita Kengo Toyomura Suminori Kono Takashi Ueki Masao Tanaka Yoshihiro Kakeji Yoshihiko Maehara Takeshi Okamura Koji Ikejiri Kitaroh Futami Takafumi Maekawa Yohichi Yasunami Kenji Takenaka Hitoshi Ichimiya Reiji Terasaka | 2013 | World Journal of Gastroenterology2013,19,17: | 12 |
| 5 | Analysis of the risk factors for severity in post endoscopic retrograde cholangiopancreatography pancreatitis: The indication of prophylactic treatments显示文摘AIM To determine the risk factors of severe post endoscopic retrograde cholangiopancreatography pancreatitis(s PEP) and clarify the indication of prophylactic treatments.METHODS At our hospital, endoscopic retrograde cholangiopancreatography(ERCP) was performed on 1507 patients from May 2012 to December 2015. Of these patients, we enrolled all 121 patients that were diagnosed with post endoscopic retrograde PEP. Fourteen of 121 patients diagnosed as s PEP were analyzed.RESULTS Forty-one patients had contrast media remaining in the pancreatic duct after completion of ERCP. Seventy-one patients had abdominal pain within three hours after ERCP. These were significant differences for s PEP(P < 0.05). The median of Body mass index, the median time for ERCP, the median serum amylase level of the next day, past histories including drinking and smoking, past history of pancreatitis, sphincter of Oddi dysfunction, whether emergency or not, expertise of ERCP procedure, diverticulum nearby Vater papilla, whether there was sphincterotomy or papillary balloon dilation, pancreatic duct cannulation, use of intraductal ultrasonography enforcement, and transpapillary biopsies had no significant differences with s PEP.CONCLUSION Contrast media remaining in the pancreatic duct and the appearance of abdominal pain within three hours after ERCP were risk factors of s PEP. | Hiroshi Matsubara Fumihiro Urano Yuki Kinoshita Shozo Okamura Hiroki Kawashima Hidemi Goto Yoshiki Hirooka | 2017 | World Journal of Gastrointestinal Endoscopy2017,9,4: | 12 |

| 8 | Analysis of colonoscopic perforations at a local clinic and a tertiary hospital显示文摘AIM:To define the clinical characteristics,and to assess the management of colonoscopic complications at a local clinic.METHODS:A retrospective review of the medical records was performed for the patients with iatrogenic colon perforations after endoscopy at a local clinic between April 2006 and December 2010.Data obtained from a tertiary hospital in the same region were also analyzed.The underlying conditions,clinical presentations,perforation locations,treatment types(operative or conservative) and outcome data for patients at the local clinic and the tertiary hospital were compared.RESULTS:A total of 10 826 colonoscopies,and 2625 therapeutic procedures were performed at a local clinic and 32 148 colonoscopies,and 7787 therapeutic procedures were performed at the tertiary hospital.The clinic had no perforations during diagnostic colonoscopy and 8(0.3%) perforations were determined to be related to therapeutic procedures.The perforation rates in each therapeutic procedure were 0.06%(1/1609) in polypectomy,0.2%(2/885) in endoscopic mucosal resection(EMR),and 3.8%(5/131) in endoscopic submucosal dissection(ESD).Perforation rates for ESD were significantly higher than those for polypectomy or EMR(P < 0.01).All of these patients were treated conservatively.On the other hand,three(0.01%) perforation cases were observed among the 24 361 diagnostic procedures performed,and these cases were treated with surgery in a tertiary hospital.Six perforations occurred with therapeutic endoscopy(perforation rate,0.08%;1 per 1298 procedures).Perforation rates for specific procedure types were 0.02%(1 per 5500) for polypectomy,0.17%(1 per 561) for EMR,2.3%(1 per 43) for ESD in the tertiary hospital.There were no differences in the perforation rates for each therapeutic procedure between the clinic and the tertiary hospital.The incidence of iatrogenic perforation requiring surgical treatment was quite low in both the clinic and the tertiary hospital.No procedure-related mortalities occurred.Performing closure with endoscopic clipping reduced the C-reactive protein(CRP) titers.The mean maximum CRP titer was 2.9 ± 1.6 mg/dL with clipping and 9.7 ± 6.2 mg/dL without clipping,respectively(P < 0.05).An operation is indicated in the presence of a large perforation,and in the setting of generalized peritonitis or ongoing sepsis.Although we did not experience such case in the clinic,patients with large perforations should be immediately transferred to a tertiary hospital.Good relationships between local clinics and nearby tertiary hospitals should therefore be maintained.CONCLUSION:It was therefore found to be possible to perform endoscopic treatment at a local clinic when sufficient back up was available at a nearby tertiary hospital. | Toshihiko Sagawa Satoru Kakizaki Haruhisa Iizuka Yasuhiro Onozato Naondo Sohara Shinichi Okamura Masatomo Mori | 2012 | World Journal of Gastroenterology2012,18,35: | 5 |
| 9 | Prophylactic lateral pelvic lymph node dissection in stage Ⅳ low rectal cancer显示文摘AIM To assess the clinical significance of prophylactic lateral pelvic lymph node dissection (LPLND) in stage Ⅳ low rectal cancer.METHODS We selected 71 consecutive stage Ⅳ low rectal cancer patients who underwent primary tumor resection,and enrolled 50 of these 71 patients without clinical LPLN metastasis.The patients had distant metastasis such as liver,lung,peritoneum,and paraaortic LN.Clinical LPLN metastasis was defined as LN with a maximum diameter of 10 mm or more on preoperative pelvic computed tomography scan.All patients underwent primary tumor resection,27 patients underwent total mesorectal excision(TME) with LPLND(LPLND group),and 23 patients underwent only TME(TME group).Bilateral LPLND was performed simultaneously with primary tumor resection in LPLND group.R0 resection of both primary and metastatic sites was achieved in 20 of 50 patients.We evaluated possible prognostic factors for 5-year overall survival (OS),and compared 5-year cumulative local recurrence between the LPLND and TME groups.RESULTS For OS,univariate analyses revealed no significant benefit in the LPLND compared with the TME group (28.7% vs 17.0%,P = 0.523); multivariate analysis revealed that R0 resection was an independent prognostic factor.Regarding cumulative local recurrence,the LPLND group showed no significant benefit compared with TME group (21.4% vs 14.8%,P = 0.833).CONCLUSION Prophylactic LPLND shows no oncological benefits in patients with Stage Ⅳ low rectal cancer without clinical LPLN metastasis. | Hiroshi Tamura Yoshifumi Shimada Hitoshi Kameyama Ryoma Yagi Yosuke Tajima Takuma Okamura Mae Nakano Masato Nakano Masayuki Nagahashi Jun Sakata Takashi Kobayashi Shin-ichi Kosugi Hitoshi Nogami Satoshi Maruyama Yasumasa Takii Toshifumi Wakai | 2017 | World Journal of Clinical Oncology2017,8,5: | 4 |

| 13 | Disruption of the TWEAK/Fn14 pathway prevents 5-fluorouracil-induced diarrhea in mice显示文摘AIM To clarify the roles of TWEAK and its receptor Fn14 in 5-fluorouracil(5-FU)-induced diarrhea.METHODS Diarrhea was induced in wild-type(WT), Fn14 knockout(KO), and IL-13 receptor(IL-13R)α1 KO BALB/c mice using a single injection of 5-FU. Histological analysis, cytokine analysis, and flow cytometry was performed on ileal tissues and cells. Murine colon carcinomabearing mice were co-treated with an anti-TWEAK antibody and 5-FU. Embryonic fibroblast response to cytokines was also analyzed.RESULTS5-FU induced high Fn14 expression in epithelial cells. The severity of 5-FU-induced diarrhea was lower in Fn14 KO mice compared with WT mice. Administration of anti-TWEAK antibody reduced 5-FU-induced diarrhea without affecting the antitumor effects of 5-FU in vivo. 5-FU-induced expression of IL-13, IL-17 A, TNF-α, and IFN-γ in the ileum was Fn14 dependent. The severity of 5-FU-induced diarrhea was lower in IL-13Rα1 KO mice, indicating major role for IL-13 signaling via IL-13Rα1 in pathogenesis. We found that IL-13Rα2, an IL-13 neutralizing/cell protective receptor, was strongly induced by IL-33 in vitro and in vivo. IL-13Rα2 was upregulated in the ileum of 5-FU-treated Fn14 KO mice. Thus, the deletion of Fn14 upregulated IL-13Rα2 expression, which reduced IL-13 expression and activity. CONCLUSION Disruption of the TWEAK/Fn14 pathway affects several interconnected pathways, including those associated with IL-13, IL-33, and IL-13Rα2, to attenuate 5-FUinduced intestinal side effects. | Takuhito Sezaki Yuki Hirata Teruki Hagiwara Yuki I Kawamura Tadashi Okamura Rieko Takanashi Kenta Nakano Miwa Tamura-Nakano Linda C Burkly Taeko Dohi | 2017 | World Journal of Gastroenterology2017,23,13: | 3 |
| 14 | Femtosecond pulses cleaning by transient-grating process in Kerr-optical media显示文摘We use a transient-grating (TG) process in a Kerr bulk medium to clean a femtosecond laser pulse. Using the technique, the temporal contrast of the generated TG signal is improved by more than two orders of magnitude in comparison with the incident pulse in a 0.5-mm-thick fused silica plate. The laser spectrum is smoothed and broadened, and the pulse duration is shortened simultaneously. We expect to extend this technique to a clean pulse with broadband spectral bandwidth at a wide spectral range because it is a phase-matched process. | Kotaro Okamura Yuichiro Kida Takayoshi Kobayashi | 2011 | Chinese Optics Letters2011,9,5: | 3 |

| 16 | Hilar cholangiocarcinoma with intratumoral calcification: A case report显示文摘This report describes a rare case of hilar cholangiocarcinoma with intratumoral calcification that mimicked hepatolithiasis. A 73-year-old man presented to a local hospital with a calcified lesion in the hepatic hilum. At first,hepatolithiasis was diagnosed,and he underwent endoscopic stone extraction via the transpapillary route. This treatment strategy failed due to biliary stricture. He was referred to our hospital,and further examination suggested the existence of cholangiocarcinoma. He underwent left hepatectomy with caudate lobectomy and extrahepatic bile duct resection. Pathological examination revealed hilar cholangiocarcinoma with intratumoral calcification,while no stones were found. To the best of our knowledge,only one case of calcified hilar cholangiocarcinoma has been previously reported in the literature. Here,we report a rare case of calcified hilar cholangiocarcinoma and reveal its clinicopathologic features. | Kazuho Inoko Takahiro Tsuchikawa Takehiro Noji Yo Kurashima Yuma Ebihara Eiji Tamoto Toru Nakamura Soichi Murakami Keisuke Okamura Toshiaki Shichinohe Satoshi Hirano | 2015 | World Journal of Gastroenterology2015,21,38: | 2 |
| 17 | 抗生素链霉菌与弗氏链霉菌原生质体的种间电融合显示文摘许多链霉菌能够合成抗生素、酶及抗肿瘤剂等各种重要产物。最近,原生质体融合已经成为菌株改良的有效技术。对于链霉菌原生质体融合,几乎专门使用聚乙二醇(PEG)作促融剂。然而,同新发展的电融合法比较,该法存在许多缺点。因此,电融合法正成为酵母、植物及动物细胞融合的常规方法。虽然电融合法正在不同范围内推广使用,但对于像链霉菌这么小的原生质体,至今尚未加以应用。本文论述由抗生素链霉菌a20和弗氏链霉菌f2所制备的原生质体的电融合。利用由显微镜载玻片和铝箔构成的微型融合室来监测链霉菌原生质体的融合过程。 | Tokumitsu Okamura 廖福荣 | 1990 | 国外医药(抗生素分册)1990,11,4: | 2 |
