| 1 | Prognosis of hepatocellular carcinoma accompanied by microscopic portal vein invasion显示文摘AIM:To investigate the prognostic factors in patients with hepatocellular carcinoma(HCC) accompanied by microscopic portal vein invasion(PVI).METHODS:Of the 267 patients with HCC undergoing hepatic resection at Aso Iizuka Hospital,71 had PVI.After excluding 16 patients with HCC that invaded the main trunk and the first and second branches of the portal vein,55 patients with microscopic PVI were enrolled.RESULTS:The patients with HCC accompanied by microscopic invasion were divided into two groups:solitary PVI(PVI-S:n = 44),and multiple PVIs(PVI-M:n = 11).The number of portal vein branches invaded by tumor thrombi was 5.4 ± 3.8(2-16) in patients with PVI-M.In cumulative survival,PVI-M was found to be a significantly poor prognostic factor(P = 0.0019);while PVI-M and non-anatomical resection were significantly poor prognostic factors in disease-free survival(P = 0.0213,and 0.0115,respectively).In patients with PVI-M,multiple intrahepatic recurrence was more common than in the patients with PVI-S(P = 0.0049).In patients with PVI-S,non-anatomical resection was a significantly poor prognostic factor in disease-free survival(P = 0.0370).Operative procedure was not a significant prognostic factor in patients with PVI-M.CONCLUSION:The presence of PVI-M was a poor prognostic factor in patients with HCC,accompanied by microscopic PVI.Anatomical resection is recommended in these patients with HCC.Patients with HCC and PVI-M may also be good candidates for adjuvant chemotherapy. | Ken Shirabe Kiyoshi Kajiyama Norifumi Harimoto Hideaki Masumoto Tatsuro Fukuya Masafumi Ooya Yoshihiko Maehara | 2009 | World Journal of Gastroenterology2009，15，21： | 10 |
| 2 | Therapeutic strategy for postoperative recurrence in patients with non-small cell lung cancer显示文摘Postoperative recurrence occurs in approximately half of patients with non-small cell lung cancer(NSCLC), even after complete resection. Disease recurrence after surgical resection reduces the patient's life expectancy sharply. The prognosis after postoperative recurrence is considered to largely depend on both the mode of first recurrence(distant, locoregional or combined) and the treatment modality:(1) The majority of cases of postoperative recurrence involve distant metastasis with or without locoregional recurrence. Platinum-based systemic chemotherapy is practically accepted as the treatment for these diseases on the basis of evidence for original stage Ⅳ disease. The advent of both pemetrexed and molecular-targeted drugs has improved the survival of nonsquamous NSCLC and changed the chemotherapeutic algorithm for NSCLC;(2) Among patients with distant metastatic recurrence without locoregional recurrence at the primary tumor site, the metastasis is often limited in both organ and number. Such metastases are referred to as oligometastases. Local therapy, such as surgical resection and radiotherapy, has been suggested to be the first-line treatment of choice foroligometastatic recurrence; and(3) While locoregional recurrence is likely to cause troublesome symptoms, it is a potentially limited disease. Therefore, providing local control is important, and radiation is usually beneficial for treating local recurrence. In order to obtain better control of the disease and provide treatment with curative intent in patients with limited disease, the administration of concurrent platinum-based chemoradiotherapy is recommended according to the results of originally nonresectable stage ⅢA and ⅢB disease. | Tokujiro Yano Tatsuro Okamoto Seiichi Fukuyama Yoshihiko Maehara | 2014 | World Journal of Clinical Oncology2014，5，5： | 10 |
| 3 | A prospective randomized trial of lafutidine vs rabeprazole on post-ESD gastric ulcers显示文摘AIM:To compare the effects of rabeprazole and lafutidine on post-endoscopic submucosal dissection(ESD) gastric ulcers.METHODS:Patients with gastric tumors indicated for ESD were prospectively studied.After ESD,all patients were treated with intravenous omeprazole for the first 3 d.Patients were then randomly assigned to oral lafutidine or rabeprazole.Ulcer size,ulcer size reduction rate,and ulcer stage were evaluated 4 wk later.Occurrence of complication was monitored throughout the 4-wk period.RESULTS:Sixty five patients were enrolled in the study,and 60 patients were subjected to the final analysis.In the lafutidine group(30 lesions in 29 patients),initial and 4-wk post-ESD ulcer sizes were 33.3 ± 9.2 and 10.5 ± 4.8 mm,respectively.In the rabeprazole group(34 lesions in 31 patients),the values were 34.7 ± 11.3 and 11.8 ± 6.7 mm,respectively.Ulcer size reduction rates in lafutidine and rabeprazole groups were 32.3% and 33.5%,respectively(P=0.974).Ulcer stage 4 wk post-ESD did not differ significantly between the two groups(P=0.868).Two cases in the rabeprazole group and no cases in the lafutidine group developed ulcer bleeding during the oral dose period,although the difference of bleeding rate between the two groups was not statistically significant(P=0.157).CONCLUSION:Lafutidine and rabeprazole have equivalent therapeutic effects on post-ESD gastric ulcers. | Tomohiko Richard Ohya Hiroki Endo Kei Kawagoe Tatsuro Yanagawa Katsuhiro Hanawa Ken Ohata Masako Asayama Kantaro Hisatomi Takuma Teratani Toshiaki Gunji Hajime Sato Nobuyuki Matsuhashi | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，1： | 7 |
| 4 | Two-week treatment with proton pump inhibitor is sufficient for healing post endoscopic submucosal dissection ulcers显示文摘AIM:To investigate the optimum period of treatment for post endoscopic submucosal dissection(ESD)ulcers.METHODS:Patients who underwent ESD for gastric cancer were randomized to two groups and treated with esomeprazole 20 mg per day for 4 wk(4W group)or 2 wk(2W group).At 4 wk after ESD,we measured the size of the artificial ulcers by endoscopy and determined the ulcer healing rate,compared with the size of the ESD specimens.This randomized controlled trial study was approved by our ethics committee and registered in the UMIN Clinical Trial Registry.RESULTS:A total of 60 consecutive patients were included in the study.All patients received rebamipide 300 mg per day for 4 wk.One patient in 2W group who showed bleeding within two weeks and received endoscopic treatment was excluded from further analysis.The numbers of patients with ulcers in the healing/scar stage in the 2W and 4W groups at 4 wk after ESD were 20/6 and 28/5,respectively,with no significant difference.The ulcer healing rate in the 2W and 4W groups were 96.1%[95%confidence interval(CI):94.6%-97.55]vs 94.8%(95%CI:92.6%-97.1%),respectively,with no statistical difference(UMIN000006951).CONCLUSION:Two-wk treatment with a proton pump inhibitor is as effective as four-week treatment for healing post ESD ulcers. | Makoto Arai Tomoaki Matsumura Kenichiro Okimoto Arata Oyamada Keiko Saito Shoko Minemura Daisuke Maruoka Takeshi Tanaka Tomoo Nakagawa Tatsuro Katsuno Osamu Yokosuka | 2014 | World Journal of Gastroenterology2014，20，43： | 6 |
| 5 | Lactogenic hormones alter cellular and extracellular microRNA expression in bovine mammary epithelial cell culture显示文摘Background: Bovine milk contains not only a variety of nutritional ingredients but also micro RNAs(mi RNAs) that are thought to be secreted by the bovine mammary epithelial cells(BMECs). The objective of this study was to elucidate the production of milk-related mi RNAs in BMECs under the influence of lactogenic hormones.Results: According to a microarray result of milk exosomal mi RNAs prior to cellular analyses, a total of 257 mi RNAs were detected in a Holstein cow milk. Of these, 18 major mi RNAs of interest in the milk were selected for an expression analysis in BMEC culture that was treated with or without dexamethasone, insulin, and prolactin(DIP) to induce a lactogenic differentiation. Quantitative polymerase chain reaction(q PCR) results showed that the expressions of mi R-21–5p(P = 0.005), mi R-26a(P = 0.016), and mi R-320a(P = 0.011) were lower in the DIP-treated cells than in the untreated cells. In contrast, the expression of mi R-339a(P = 0.017) in the cell culture medium were lower in the DIP-treated culture than in the untreated culture. Intriguingly, the mi R-148 a expression in cell culture medium was elevated by DIP treatment of BMEC culture(P = 0.018). The medium-to-cell expression ratios of mi R-103(P = 0.025), mi R-148a(P < 0.001), and mi R-223(P = 0.013) were elevated in the DIP-treated BMECs, suggesting that the lactogenic differentiation-induced secretion of these three mi RNAs in BMECs. A bioinformatic analysis showed that the mi RNAs down-regulated in the BMECs were associated with the suppression of genes related to transcriptional regulation, protein phosphorylation, and tube development.Conclusion: The results suggest that the mi RNAs changed by lactogenic hormones are associated with milk protein synthesis, and mammary gland development and maturation. The elevated mi R-148 a level in DIP-treated BMECs may be associated with its increase in milk during the lactation period of cows. | Susumu Muroya Tatsuro Hagi Ataru Kimura Hisashi Aso Masatoshi Matsuzaki Masaru Nomura | 2016 | Journal of Animal Science and Biotechnology2016，7，4： | 5 |

| 7 | An unusual enteropathy-associated T-cell lymphoma with MYC translocation arising in a Japanese patient:A case report显示文摘Enteropathy-associated T-cell lymphoma(EATL) is a rare peripheral T-cell lymphoma classified into 2 types,with or without celiac disease,based on histology.Type 2 EATL is less commonly associated with celiac disease,in which cells are characterized by being monomorphic and small-to medium-sized.Cells are characterized by CD8 and CD56 expression and c-MYC oncogene locus gain.We present an atypical case of type 2 EATL in the jejunum,with human T-lymphotropic virus-1 that was CD4-CD8+ CD56-CD30-CD25-TIA-1+ and granzyme B+ on immunohistological staining.It also displayed translocation of chromosome 8p24(c-MYC),as determined by fluorescent in situ hybridization.Mucosal spreading and intraepithelial invasion by lymphoma with villous atrophy were detected adjacent to the mucosal layer.The lymphoma may be derived from intraepithelial CD8+ T cells,similar to celiac disease. | Kenji Okumura Masahiko Ikebe Tatsuro Shimokama Morishige Takeshita Nao Kinjo Keishi Sugimachi Hidefumi Higashi | 2012 | World Journal of Gastroenterology2012，18，19： | 3 |
| 8 | Alpha-fetoprotein before and after pegylated interferon therapy for predicting hepatocellular carcinoma development显示文摘AIM: To investigate factors that accurately predict hepatocellular carcinoma(HCC) development after antiviral therapy in chronic hepatitis C(CHC) patients. METHODS: CHC patients who received pegylated interferon and ribavirin were enrolled in this cohort study that investigated the ability of alpha-fetoprotein(AFP) to predict HCC development after interferon(IFN) therapy. RESULTS: Of 1255 patients enrolled, 665 developed sustained virological response(SVR) during mean follow-up period of 5.4 years. HCC was occurred in 89 patients, and 20 SVR patients were included. Proportional hazard models showed that HCC occurred in SVR patients showing AFP ≥ 5 ng/m L before therapy and in non-SVR patients showing AFP ≥ 5 ng/m L before and 1 year after therapy besides older age, and low platelet counts. SVR patients showing AFP ≥ 5 ng/m L before therapy and no decrease in AFP to < 5 ng/m L 1 year after therapy had significantly higher HCC incidence than non-SVR patients showing AFP ≥ 5 ng/m L before therapy and decreased AFP(P = 0.043). AFP ≥ 5 ng/m L before therapy was significantly associated with low platelet counts and high values of alanine aminotransferase(ALT) in stepwise logistic regression analysis. After age, gender, platelet count, and ALT was matched by propensity score, significantly lower HCC incidence was shown in SVR patients showing AFP < 5 ng/m L before therapy than in those showing AFP ≥ 5 ng/m L.CONCLUSION: The criteria of AFP < 5 ng/m L before and 1 year after IFN therapy is a benefical predictor for HCC development in CHC patients. | Yasuto Takeuchi Fusao Ikeda Toshiya Osawa Yasuyuki Araki Kouichi Takaguchi Youichi Morimoto Noriaki Hashimoto Kousaku Sakaguchi Tatsuro Sakata Masaharu Ando Yasuhiro Makino Shuji Matsumura Hiroki Takayama Hiroyuki Seki Shintarou Nanba Yuki Moritou Tetsuya Yasunaka Hideki Ohnishi Akinobu Takaki Kazuhiro Nouso Yoshiaki Iwasaki Kazuhide Yamamoto | 2015 | World Journal of Hepatology2015，7，19： | 3 |
| 9 | Case of autoimmune hepatitis with markedly enlarged hepatoduodenal ligament lymph nodes显示文摘Autoimmune hepatitis(AIH) is a necroinflammatory liver disease of unknown etiology.The disease is characterized histologically by interface hepatitis,biochemically by increased aspartate aminotransferase and alanine aminotransferase levels,and serologically by increased autoantibodies and immunoglobulin G levels.Here we discuss AIH in a previously healthy 37-year-old male with highly elevated serum levels of soluble interleukin-2 receptor and markedly enlarged hepatoduodenal ligament lymph nodes(HLLNs,diameter,50 mm).Based on these observations,the differential diagnoses were AIH,lymphoma,or Castleman's disease.Liver biopsy revealed the features of interface hepatitis without bridging fibrosis along with plasma cell infiltration which is the typical characteristics of acute AIH.Lymph node biopsy revealed lymphoid follicles with inflammatory lymphocytic infiltration;immunohistochemical examination excluded the presence of lymphoma cells.Thereafter,he was administered corticosteroid therapy:after 2 mo,the enlarged liver reached an almost normal size and the enlarged HLLNs reduced in size.We could not find AIH cases with such enlarged lymph nodes(diameter,50 mm) in our literature review.Hence,we speculate that markedly enlarged lymph nodes observed in our patient may be caused by a highly activated,humoral immune response in AIH. | Hideki Fujii Naoki Ohnishi Kazuho Shimura Masafumi Sakamoto Tohru Ohkawara Yoshihiko Sawa Koichi Nishida Yasuo Ohkawara Tatsuro Kobata Kanji Yamaguchi Yoshito Itoh | 2013 | World Journal of Gastroenterology2013，19，11： | 3 |
| 10 | 钢铁中多元夹杂物颗粒的三维评估显示文摘为了从钢铁中提取各种夹杂物颗粒,考察了采用无水电解质的恒电位和恒电流的提取方法。结果认为,4%的MS[4%(V/V)甲基水杨酸-1%(m/V)水杨酸-1%(m/V)四甲基氯化铵-甲醇)和10%AA(10%(V/V)乙酰丙酮-1%(m/V)四甲基氯化铵-甲醇]电解质溶液适用于提取钢铁中夹杂物TiOx和TiAl2O5。尽管这些电解提取法可以提取化学性能不稳定的夹杂物颗粒,然而,因为对夹杂物的观察是在萃取完成后于一个滤膜中进行,因此无法确定金属中每种夹杂物的具体位置。为了确定金属中夹杂物的具体位置,将卤-醇的光蚀刻方法用于以Ti和Al除氧的钢样品表面附近出现的夹杂颗粒,使用扫描电子显微技术和俄歇电子能谱(AES)对精细夹杂物颗粒形貌、尺寸和元素的偏析进行评估,不过卤醇却和钢铁中的金属钛和金属铝发生还原反应。对微小夹杂物颗粒的成分的形态、分离进行估测,然后,使用一种低加速能-扫描电子显微技术和俄歇电子能谱(AES)对用聚焦离子束制备微小夹杂物颗粒截面上元素的微观偏析进行评定。在这些研究结果基础上讨论了多元夹杂物颗粒的形成机理。 | RY0 noue KEI iyokawa KOICHIRO Tomoda SHIGERU Ueda TATSURO Ariyama | 2012 | 冶金分析2012，32，8： | 2 |
