| 1 | Effect of Cooling Method on Microstructure and Mechanical Properties of Hot-Rolled C-Si-Mn TRIP Steel显示文摘The controlled cooling technology following hot rolling process is a vital factor that affects the final microstructure and mechanical properties of the hot-rolled transformation induced plasticity(TRIP) steels.In the present study,low alloy C-Si-Mn TRIP steel was successfully fabricated by hot rolling process with a 450 hot rolling mill.To maximize the volume fraction and stability of retained austenite of the steel,two different cooling methods(air-cooling and ultra-fast cooling 'AC-UFC' and ultra-fast cooling,air-cooling and ultra-fast cooling 'UFC-AC-UFC') were conducted.The effects of the cooling method on the microstructure of hot-rolled TRIP steel were investigated via optical microscope,transmission electron microscope and conversion electron Mssbauer spectroscope.The mechanical properties of the steel were also evaluated by conventional tensile test.The results indicated that ferrite and bainite in the microstructure were refined with the cooling method of UFC-AC-UFC.The morphology of retained austenite was also changed from small islands distributing in bainite district(obtained with AC-UFC) to granular shape locating at the triple junction of the ferrite grain boundaries(obtained with UFC-AC-UFC).As a result,the TRIP steel with a content of retained austenite of 11.52%,total elongation of 32% and product of tensile strength and total elongation of 27 552 MPa·% was obtained. | LIU Ji-yuan ZHANG Zi-cheng ZHU Fu-xian LI Yan-mei Manabe Ken-ichi | 2012 | Journal of Iron and Steel Research(International)2012,19,1: | 11 |
| 2 | Gastric adenocarcinoma of fundic gland type spreading to heterotopic gastric glands显示文摘Herein, we present a case of gastric adenocarcinoma of fundic gland type(GA-FG) spreading to heterotopic gastric glands(HGG) in the submucosa. A 58-year-old man with epigastric pain was referred to our hospital and underwent an esophagogastroduodenoscopy. A Borrmann type II gastric cancer at the antrum and a 10 mm submucosal tumor-like lesion in the lesser curvature of the upper third of the stomach were detected. Histological examination of the biopsy specimens obtained from the submucosal tumorlike lesion suggested a GA-FG. Therefore, endoscopic submucosal dissection was performed as excisional biopsy, and histopathological examination of the resected specimen confirmed a GA-FG and HGG proximal to the GA-FG. Although the GA-FG invaded the submucosal layer slightly, the submucosal lesion of the GA-FG had a poor stromal reaction and was located just above the HGG in the submucosa. Therefore, wefinally diagnosed the lesion as a GA-FG invading the submucosal layer by spreading to HGG. | Shigeo Manabe Ken-ichi Mukaisho Takayuki Yasuoka Fumitaka Usui Tatsuzo Matsuyama Ikuhiro Hirata Yoshio Boku Shuji Takahashi | 2017 | World Journal of Gastroenterology2017,23,38: | 6 |
| 3 | Invasive group B streptococcal infection in a patient with post splenectomy for hypersplenism secondary to liver cirrhosis and portal hypertension显示文摘BACKGROUND:Splenectomy in patients with liver cirrhosis(LC)is expected to become more common owing to its efficacy on portal hemodynamics.In this report we describe an alarming case of group B streptococcus(GBS)infection after splenectomy in a patient with LC.METHODS:A 72-year-old woman with a history of LC was admitted to our emergency department because of respiratory failure.The patient had received left lateral segmentectomy of the liver and splenectomy three months before admission.Pulmonary examination revealed significant wheezing during inspiration and expiration,but no crackles and stridor.Chest radiography and CT showed no infiltrates.A presumptive diagnosis of bronchial asthma caused by upper respiratory infection was made.Four days after admission,GBS infection was confirmed by blood culture and penicillin G was administered.Antibiotics were given intravenously for a total of 12 days.RESULTS:The patient was discharged on the 12th day after admission.CONCLUSIONS:Although efficacy of splenectomy in patients with LC has been reported,immune status should be evaluated for a longer period.Patients who have undergone splenectomy are highly susceptible to bacteria;moreover,LC itself is an independent risk factor for mortality in patients with sepsis.Since prophylaxis against GBS has not been established,immediate action should be taken.Emergency physicians should be aware of invasive GBS infection in the context of the critical risk factors related to splenectomy and LC,particularly the expected increase of splenectomy performed in LC patients. | Tomoya Okazaki Toru Hifumi Arisa Manabe Hikari Matsumura Satoshi Egawa Hideyuki Hamaya Nastuyo Shinohara Koshiro Takano Hajime Shishido Yuko Abe Kenya Kawakita Masanobu Hagiike Yasuhiro Kuroda | 2016 | World Journal of Emergency Medicine2016,7,1: | 6 |
| 4 | Endoscopic submucosal dissection as excisional biopsy for anorectal malignant melanoma:A case report显示文摘BACKGROUND Anorectal malignant melanoma (AMM) is a rare disorder with an extremely poor prognosis. Although there is currently no consensus on the treatment methods for AMM, surgical procedures have been the most common treatment methods used until now. We recently encountered a case of AMM that we diagnosed using endoscopic submucosal dissection (ESD). To our knowledge, this is the first case of ESD for AMM, suggesting that ESD can potentially be a diagnostic and treatment method for AMM. CASE SUMMARY A 77-year-old woman visited our hospital with a chief complaint of anal bleeding and a palpable rectal mass. Colonoscopy revealed a 20-mm protruded lesion in the lower rectum. After obtaining biopsy specimens from the lesion, although a malignant rectal tumor was suspected, a definitive diagnosis was not made. Endoscopic ultrasonography revealed tumor invasion into the submucosal layer but not the muscular layer. Therefore, we performed an excisional biopsy using ESD. Immunohistochemical examination of the ESD-resected specimen revealed tumor cells positive for Human Melanin Black-45, Melan-A, and S-100. Moreover, the tumor cells lacked melanin pigment;thus, a diagnosis of amelanotic AMM was made. Although the AMM had massively invaded the submucosal layer and both lymphatic and venous invasion were present, we closely monitored the patient without any additional therapy on the basis of her request. Six months after ESD, local recurrence was detected, and the patient consented to wide local excision. CONCLUSION It is suggested that ESD is a potential diagnostic and treatment method for AMM. | Shigeo Manabe Yoshio Boku Michiyo Takeda Fumitaka Usui Ikuhiro Hirata Shuji Takahashi | 2019 | World Journal of Clinical Cases2019,7,13: | 6 |
| 5 | Factors associated with complicated erosive esophagitis: A Japanese multicenter, prospective, cross-sectional study显示文摘AIM To assess the clinical characteristics of patients with complicated erosive esophagitis(EE) and their associated factors.METHODS This prospective, cross-sectional study included patients diagnosed with EE by upper gastrointestinal endoscopy between October 2014 and March 2015 at 106 Japanese hospitals. Data on medical history, general condition, gastrointestinal symptoms, lifestyle habits, comorbidities, and endoscopic findings were collected using a standard form to create a dedicated database. Logistic regression analysis was used to calculate adjusted odds ratios(aO R) and 95%CI for the association with complicated EE.RESULTS During the study period, 1749 patients diagnosed with EE, 38.3% of whom were prescribed proton pump inhibitors(PPIs) were included. Of them, 143(8.2%) had EE complications. Esophageal bleeding occurred in 84(4.8%) patients, esophageal strictures in 45(2.6%) patients, and 14(0.8%) patients experienced both. Multivariate analysis showed that increased age(a OR: 1.05; 95%CI: 1.03-1.08), concomitant use of psychotropic agents(a OR: 6.51; 95%CI: 3.01-13.61), and Los Angeles grades B(a OR: 2.69; 95%CI: 1.48-4.96), C(aO R: 15.38; 95%CI: 8.62-28.37), and D(aO R: 71.49; 95%CI: 37.47-142.01) were significantly associated with complications, whereas alcohol consumption 2-4 d/wk was negatively associated(a OR: 0.23; 95%CI: 0.06-0.61). Analyzing associated factors with each EE complication separately showed esophageal ulcer bleeding were associated with increased age(a OR: 1.05; 95%CI: 1.02-1.07) and Los Angeles grades B(aO R: 3.60; 95%CI: 1.52-8.50), C(a OR: 27.61; 95%CI: 12.34-61.80), and D(a OR: 119.09; 95%CI: 51.15-277.29), while esophageal strictures were associated with increased age(a OR: 1.07; 95%CI: 1.04-1.10), gastroesophageal reflux symptom(aO R: 2.51; 95%CI: 1.39-4.51), concomitantuse of psychotropic agents(a OR: 11.79; 95%CI: 5.06-27.48), Los Angeles grades C(aO R: 7.35; 95%CI: 3.32-16.25), and D(a OR: 20.34; 95%CI: 8.36-49.53) and long-segment Barrett's esophagus(a OR: 4.63; 95%CI: 1.64-13.05).CONCLUSION Aging and severe EE were common associated factors, although there were more associated factors in esophageal strictures than esophageal ulcer bleeding. Despite the availability and widespread use of PPIs, EE complications are likely to remain a problem in Japan owing to the aging population and high-stress society. | Masahiro Sakaguchi Noriaki Manabe Nobuo Ueki Jun Miwa Tomoki Inaba Norimasa Yoshida Kouichi Sakurai Masahiro Nakagawa Hajime Yamada Michiya Saito Koji Nakada Katsuhiko Iwakiri Takashi Joh Ken Haruma | 2017 | World Journal of Gastroenterology2017,23,2: | 3 |

| 7 | Randomized study of lafutidine vs lansoprazole in patients with mild gastroesophageal reflux disease显示文摘AIM: To compare the clinical efficacy of the secondgeneration H2 RA lafutidine with that of lansoprazole in Japanese patients with mild gastroesophageal reflux disease(GERD). METHODS: Patients with symptoms of GERD and a diagnosis of grade A reflux esophagitis(according to the Los Angeles classification) were randomized to receive lafutidine(10 mg, twice daily) or lansoprazole(30 mg, once daily) for an initial 8 wk, followed by maintenance treatment comprising half-doses of the assigned drug for 24 wk. The primary endpoint was the frequency and severity of heartburn during initial and maintenance treatment. The secondary endpoints were the sum score of questions 2 and 3 in the Gastrointestinal Symptom Rating Scale(GSRS), and the satisfaction score.RESULTS: Between April 2012 and March 2013, a total of 53 patients were enrolled, of whom 24 and 29 received lafutidine and lansoprazole, respectively. After 8 wk, the frequency and severity of heartburn was significantly reduced in both groups. However, lafutidine was significantly inferior to lansoprazole with regard to the severity of heartburn during initial and maintenance treatment(P = 0.016). The sum score of questions 2 and 3 in the GSRS, and satisfaction scores were also significantly worse in the lafutidine group than the lansoprazole group(P = 0.0068 and P = 0.0048, respectively).CONCLUSION: The clinical efficacy of lafutidine was inferior to that of lansoprazole, even in Japanese patients with mild GERD. | Ryuta Takenaka Hiroyuki Okada Seiji Kawano Yoshinori Komazawa Fumiya Yoshinaga Shinji Nagata Masafumi Inoue Hirohisa Komatsu Seiji Onogawa Yoshinori Kushiyama Shinichi Mukai Hiroko Todo Hideharu Okanobu Noriaki Manabe Shinji Tanaka Ken Haruma Yoshikazu Kinoshita | 2016 | World Journal of Gastroenterology2016,22,23: | 2 |
