| 1 | 激光诱导击穿光谱技术对钢中缺陷的快速表征显示文摘激光诱导击穿光谱技术(LIBS)作为一种快速而简单地检查钢表面缺陷的技术,可直接观测到激光脉冲被聚焦于样品之上而感生的等离子体发射物。一个平凸透镜把斑直径大约为1 mm的光量开关Nd:YAG激光器(脉宽:12 ns;重复频率:10 Hz)辐照聚焦于样品表面,用来烧蚀样品的一部分,形成一个微等离子体。等离子体的发射由光纤传送至帕邢-龙校格装置多色仪(焦距:500 mm)。在已被流入和流出的氩气排空的空间里,样品被安装在一个二维移动台上进行两点分析——常规分析和缺陷分析。通过比较两个分析结果,可检测到缺陷部分有显著信号强度的元素。由不同类型的夹杂物可以检测出典型的元素,由氧化铝可检测出铝,由保护渣可检测出铝、钙、镁、硅和钠,由矿渣可检测出铝、钙和镁。经证实,由LIBS分析得到的结果与EPMA(电子探针)研究得到的结果一致。因此,导致缺陷的夹杂物的类型都能通过LIBS技术确定属性。当涂层被激光烧蚀去掉后,镀锌钢也可以被直接分析出来。包括制样,该项技术评定时间不到半小时,因此在炼钢过程中,可以迅速采取合适措施。 | KONDO Hiroyuki AIMOTO Michihiro YAMAMURA Hideaki TOH Takehiko | 2009 | 冶金分析2009，29，1： | 13 |
| 2 | Utility of linked color imaging for endoscopic diagnosis of early gastric cancer显示文摘BACKGROUND Linked color imaging(LCI) is a method of endoscopic imaging that emphasizes slight differences in red mucosal color.AIM To evaluate LCI in diagnostic endoscopy of early gastric cancer and to compare LCI and pathological findings.METHODS Endoscopic images were obtained for 39 patients(43 lesions) with early gastric cancer. Three endoscopists evaluated lesion recognition with white light imaging(WLI) and LCI. Color values in Commission Internationale de l'Eclairage(CIE)1976 L*a*b* color space were used to calculate the color difference(ΔE) between cancer lesions and non-cancer areas. After endoscopic submucosal dissection,blood vessel density in the surface layer of the gastric epithelium was evaluated pathologically. The identical region of interest was selected for analyses of endoscopic images(WLI and LCI) and pathological analyses.RESULTS LCI was superior for lesion recognition(P < 0.0001), and ΔE between cancer and non-cancer areas was significantly greater with LCI than WLI(29.4 vs 18.6, P <0.0001). Blood vessel density was significantly higher in cancer lesions(5.96% vs4.15%, P = 0.0004). An a* cut-off of ≥ 24 in CIE 1976 L*a*b* color space identified a cancer lesion using LCI with sensitivity of 76.7%, specificity of 93.0%, and accuracy of 84.9%.CONCLUSION LCI is more effective for recognition of early gastric cancer compared to WLI as a result of improved visualization of changes in redness. Surface blood vessel density was significantly higher in cancer lesions, and this result is consistent with LCI image analysis. | Toshihisa Fujiyoshi Ryoji Miyahara Kohei Funasaka Kazuhiro Furukawa Tsunaki Sawada Keiko Maeda Takeshi Yamamura Takuya Ishikawa Eizaburo Ohno Masanao Nakamura Hiroki Kawashima Masato Nakaguro Masahiro Nakatochi Yoshiki Hirooka | 2019 | World Journal of Gastroenterology2019，25，10： | 12 |

| 5 | Lentinan prolonged survival in patients with gastric cancer receiving S-1-based chemotherapy显示文摘AIM:To examine whether administration of lentinan,purifiedβ-1,3-glucan,can prolong survival in advanced gastric cancer patients receiving S-1-based chemotherapy.METHODS:Since 2004,78 patients with metastatic or recurrent gastric cancer have received S-1-based chemotherapy as first-line treatment.Survival,side effects,and the ratio of granulocytes/lymphocytes(G/L ratio)were compared between 2 groups of patients who received chemo-immunotherapy using lentinan and chemotherapy alone.RESULTS:Median overall survival was significantly longer in the former group than in the latter group[689 d(95%CI:431-2339 d)vs 565 d(95%CI:323-662 d),P=0.0406].In addition,the G/L ratio in patients who received lentinan was maintained around or below 2,which was significantly lower than that in patients who received chemotherapy alone(P<0.001).CONCLUSION:Chemo-immunotherapy with lentinan offers a significant advantage over S-1-based chemotherapy alone in terms of survival in patients with advanced gastric cancer. | Kenji Ina Ryuichi Furuta Takae Kataoka Satoshi Kayukawa Takashi Yoshida Takaya Miwa Yoshitaka Yamamura Yuuki Takeuchi | 2011 | World Journal of Clinical Oncology2011，2，10： | 10 |
| 6 | THE INTERACTION BETWEEN SHOCK WAVES AND SOLID SPHERES ARRAYS IN A SHOCK TUBE显示文摘When a shock wave interacts with a group of solid spheres, non-linear aerodynamic behaviors come into effect. The complicated wave reflections such as the Mach reflection occur in the wave propagation process. The wave interactions with vortices behind each sphere's wake cause fluctuation in the pressure profiles of shock waves. This paper reports an experimental study for the aerodynamic processes involved in the interaction between shock waves and solid spheres. A schlieren photography was applied to visualize the various shock waves passing through solid spheres. Pressure measurements were performed along different downstream positions. The experiments were conducted in both rectangular and circular shock tubes. The data with respect to the effect of the sphere array, size, interval distance, incident Mach number, etc., on the shock wave attenuation were obtained. | 施红辉 Kazuki YAMAMURA | 2004 | Acta Mechanica Sinica2004，20，3： | 10 |
| 7 | Cyclooxygenase-2 expression after preoperative chemoradiotherapy correlates with more frequent esophageal cancer recurrence显示文摘AIM: To investigate the relationship between cycloo- xygenase-2 (COX-2), and vascular endothelial growth factor (VEGF), and to determine the clinical significance of this relationship in esophageal cancer patients undergoing chemoradiotherapy (CRT). METHODS: Immunohistochemical staining was used to evaluate COX-2 and VEGF expression in 40 patients with histologically-confirmed esophageal squamous carcinoma (ESCC) who were undergoing preoperative CRT. RESULTS: Fourteen out of 40 ESCC patients showed a pathological complete response (CR) after CRT. COX-2 and VEGF protein expressions were observed in the cytoplasm of 17 and 13 tumors, respectively, with null expression in 9 and 13 tumors, respectively. COX-2 expression was strongly correlated with VEGF expression (P < 0.05). There were also significant associations between COX-2 expression, tumor recurrence, and lymph-node involvement (P = 0.0277 and P = 0.0095, respectively). COX-2 expression and VEGF expression had significant prognostic value for disease-free survival (log-rank test; P = 0.0073 and P = 0.0341, respectively), but not for overall survival, as assessed by univariate analysis. CONCLUSION: Our results suggest that COX-2 expression correlates with VEGF expression and might be a useful prognostic factor for more frequent tumor recurrence in ESCC patients undergoing neoadjuvant CRT. These findings support the use of anti-angiogenic COX-2 inhibitors in the treatment of ESCC. | Reigetsu Yoshikawa Yoshinori Fujiwara Kenji Koishi Syoudou Kojima Tomohiro Matsumoto Hidenori Yanagi Takehira Yamamura Tomoko Hashimoto-Tamaoki Takashi Nishigami Tohru Tsujimura | 2007 | World Journal of Gastroenterology2007，13，16： | 9 |
| 8 | Persistent CXCR4 expression after preoperative chemoradiotherapy predicts early recurrence and poor prognosis in esophageal cancer显示文摘AIM: To study the effect of CXC chemokine receptor-4 (CXCR4) expression on disease progression and prognosis in esophageal cancer. METHODS: CXCR4 expression was evaluated in 37 patients with histologically confirmed esophageal squamous carcinomas (ESCC) undergoing preoperative chemoradiotherapy (CRT) by immunohistochemical staining. RESULTS: Eleven out of 37 ESCC patients showed a pathological complete response (CR) after CRT. CXCR4 protein expression was observed in cell cytoplasms of 13 tumors, and null expression was seen in 13 tumors. Distant recurrence was significantly more common in patients with positive CXCR4 expression (P = 0.0318). After a median follow-up time of 31.6 mo, 19 patients progressed (12 of 19 expressed positive CXCR4) and 11 died (10 of 11 expressed positive CXCR4). Overall survival was significantly correlated with lymph node metastasis (952.1 ± 53.8 d in negative group vs 475.1 ± 56.2 d in positive group, P = 0.023), distant metastasis (874.0 ± 60.4 d in negative group vs 434.9 ± 75.2 d in positive group, P = 0.014) and CRT (811.5 ± 51.2 d in responder group vs 459.6 ± 94.0 d in non-responder group, P = 0.00038) and further with an absence ofCXCR4 expression or no residual tumor (959.8 ± 51.0 d in null expression or no tumor group vs 412.0 ± 57.1 d in positive expression group, P = 0.0001). CONCLUSION: Persistent positive CXCR4 expression is implicated in tumor aggressiveness and poor prognosis in ESCC after CRT, and preoperative CRT may improve the prognosis of ESCC via CXCL12-CXCR4 signaling pathway. | Kenji Koishi Reigetsu Yoshikawa Tohru Tsujimura Tomoko Hashimoto-Tamaoki Syoudou Kojima Hidenori Yanagi Takehira Yamamura Yoshinori Fujiwara | 2006 | World Journal of Gastroenterology2006，12，47： | 9 |
| 9 | Effects of acupuncture and moxa treatment in patients with semen abnormalities显示文摘Aim: To evaluate the effect of Chinese Traditional Medicine, acupuncture and moxa treatment, on the semen quality in patients with semen abnormalities. Methods: In a prospective, controlled and blind study, nineteen patients, aged 24 years~42 years and married for 3 years~11 years without children with semen abnormalities in concentration, morphology and/or progressive motility without apparent cause, were randomized into two groups and submitted to acupuncture and moxa treatment at the therapeutic (Study Group) and the indifferent points (Control Group), respectively, for l0 weeks. Semen analyses were performed before and after the treatment course. Results:The patients of the Study Group presented a significant increase in the percentage of normal-form sperm compared to the Control Group (calculated U=16.0, critical U=17.0). Conclusion: The Chinese Traditional Medicine acupuncture and moxa techniques significantly increase the percentage of normalform sperm in infertile patients with oligoastenoteratozoospermia without apparent cause. | Edson Gurfinkel Agnaldo P.Cedenho Ysao Yamamura Miguel Srougi | 2003 | Asian Journal of Andrology2003，5，4： | 9 |
| 10 | Characteristic endoscopic findings and risk factors for cytomegalovirus-associated colitis in patients with active ulcerative colitis显示文摘AIM: To identify characteristic endoscopic findings and risk factors for cytomegalovirus(CMV)-associated colitis in patients with active ulcerative colitis(UC).METHODS: A total of 149 UC patients admitted to the Department of Gastroenterology, Nagoya University Hospital, from January 2004 to December 2013 with exacerbation of UC symptoms were enrolled in this retrospective study. All medical records, including colonoscopy results, were reviewed. CMV infection was determined by the presence of CMV antigen, CMV inclusion bodies in biopsy specimens, or positive specific immunohistochemical staining for CMV. Multivariate analysis was used to identify independent risk factors for CMV colitis.RESULTS: Multivariate analysis indicated independent associations with the extent of disease(pancolitis) anduse of > 400 mg corticosteroids for the previous 4 wk. In contrast, no association was seen with sex, age at UC diagnosis, immunomodulator use, or infliximab use. Punched-out ulceration was also significantly associated with CMV infection in patients with active UC(odds ratio = 12.672, 95%CI: 4.210-38.143).CONCLUSION: Identification of a total corticosteroid dose > 400 mg for 4 wk, extensive colitis and a specific endoscopic finding of punched-out ulcer might facilitate the more rapid diagnosis and timely initiation of antiviral therapy for CMV-associated colitis in patients with active UC. | Yutaka Hirayama Takafumi Ando Yoshiki Hirooka Osamu Watanabe Ryoji Miyahara Masanao Nakamura Takeshi Yamamura Hidemi Goto | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，6： | 8 |
| 11 | In vivo histological diagnosis for gastric cancer using endocytoscopy显示文摘AIM To examine usefulness of virtual biopsy using endocytoscopy by comparing the in vivo endocytoscopic and histopathological images of gastric cancers.METHODS Endocytoscopy was performed in 30 patients with early gastric cancer. Of these, 26 patients showed well differentiated adenocarcinomas, while 4 patients showed poorly differentiated adenocarcinomas(including one signet ring cell carcinoma). Cancerous and non-cancerous areas were observed after double staining with 0.05% crystal violet and 0.1% methylene blue. The endocytoscopic images obtained were evaluated by an expert endoscopist and an expert pathologist without knowledge of patient clinical data, and endocytoscopic and histopathological diagnoses were compared.RESULTS The endocytoscopic images of the cancerous area were assessed as evaluable in 25(83.3%) and 27(90%) patients by endoscopist A and pathologist B, respectively, and those of the non-cancerous area as evaluable in 28(93.3%) and 23(76.7%) patients by the endoscopist and pathologist, respectively. The sensitivity, specificity, and diagnostic accuracy of gastric cancer diagnosis using evaluable endocytoscopic images were 88.0% and 92.9%, and 90.6% by endoscopist A, and 88.9% and 91.3%, and 90.0% by pathologist B, respectively. Evaluation of the diagnostic concordance rate between the endoscopist and the pathologist by inter-observer agreement calculation revealed no significant difference between the two observers. The inter-observer agreement(κ-value) for endocytoscopic diagnosis was 0.745. CONCLUSION Endocytoscopy is useful for the differentiation of cancerous from non-cancerous gastric mucosa, making it a promising tool for virtual biopsy. | Issei Tsurudome Ryoji Miyahara Kohei Funasaka Kazuhiro Furukawa Masanobu Matsushita Takeshi Yamamura Takuya Ishikawa Eizaburo Ohno Masanao Nakamura Hiroki Kawashima Osamu Watanabe Masato Nakaguro Akira Satou Yoshiki Hirooka Hidemi Goto | 2017 | World Journal of Gastroenterology2017，23，37： | 5 |

| 15 | Ectopic hepatocellular carcinoma mimicking a retroperitoneal tumor:A case report显示文摘BACKGROUND An ectopic hepatocellular carcinoma(EHCC)arises from the ectopic liver which is defined as a hepatic organ or tissue not connected to surrounding tissues.EHCC is a rare disease and it is difficult to diagnose preoperatively.Furthermore,the clinical features are not fully elucidated.CASE SUMMARY A retroperitoneal tumor(6 cm)was located at the dorsal side of the pancreas head on abdominal ultrasonography in an 81-year old woman positive for hepatitis C virus antibody.Contrast enhanced-computed tomography and gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging showed viable HCC patterns with early enhancement and delayed washout.The tumor markers-serum alphafetoprotein and alpha-fetoprotein-L3%-were increased to 30.1 ng/m L and83.1%,respectively.Protein induced by vitamin K absence or antagonist-Ⅱwas within normal levels(17 m AU/m L).Positron emission tomography-computed tomography showed strong accumulation into the tumor(Standardized Uptake Value max:13.8),and the tumor cytology following endoscopic ultrasoundguided fine needle aspiration showed poorly differentiated carcinoma.Tumor extirpation was performed,and operative findings showed that the retroperitoneal tumor was disconnected from the pancreas and the liver.Swollen lymph nodes near the tumor were histologically normal.On histological examination,the tumor was finally diagnosed as EHCC with Arginase-1 positive expression.CONCLUSION We report our experience of a rare EHCC which was difficult to diagnose,and we present a review of the literature. | Yuki Adachi Hiromitsu Hayashi Toshihiko Yusa Toru Takematsu Kazuki Matsumura Takaaki Higashi Kensuke Yamamura Takanobu Yamao Katsunori Imai Yo-ichi Yamashita Hideo Baba | 2020 | World Journal of Gastroenterology2020，26，18： | 3 |
| 16 | Double-balloon endoscopic retrograde cholangiopancreatography for patients who underwent liver operation: A retrospective study显示文摘BACKGROUND Double-balloon endoscopic retrograde cholangiography (DB-ERC) is widely performed for biliary diseases after reconstruction in gastrointestinal surgery,but there are few reports on DB-ERC after hepatectomy or living donor liver transplantation (LDLT).AIM To examine the success rates and safety of DB-ERC after hepatectomy or LDLT METHODS The study was performed retrospectively in 26 patients (45 procedures) who underwent hepatectomy or LDLT (liver operation:LO group) and 40 control patients (59 procedures) who underwent pancreatoduodenectomy (control group).The technical success (endoscope reaching the choledochojejunostomy site),diagnostic success (performance of cholangiography),therapeutic success(completed interventions) and overall success rates,insertion and procedure(completion of DB-ERC) time,and adverse events were compared between these groups.RESULTS There were no significant differences between LO and control groups in the technical [93.3%(42/45) vs 96.6%(57/59),P=0.439],diagnostic [83.3%(35/42) vs83.6%(46/55),P=0.968],therapeutic [97.0%(32/33) vs 97.7%(43/44),P=0.836],and overall [75.6%(34/45) vs 79.7%(47/59),P=0.617] success rates.The median insertion time (22 vs 14 min,P <0.001) and procedure time (43.5 vs 30 min,P=0.033) were significantly longer in the LO group.The incidence of adverse events showed no significant difference [11.1%(5/45) vs 6.8%(4/59),P=0.670].CONCLUSION DB-ERC after liver operation is safe and useful but longer time is required,so should be performed with particular care. | Ryo Nishio Hiroki Kawashima Masanao Nakamura Eizaburo Ohno Takuya Ishikawa Takeshi Yamamura Keiko Maeda Tsunaki Sawada Hiroyuki Tanaka Daisuke Sakai Ryoji Miyahara Masatoshi Ishigami Yoshiki Hirooka Mitsuhiro Fujishiro | 2020 | World Journal of Gastroenterology2020，26，10： | 3 |
| 17 | Colorectal endoscopic submucosal dissection in special locations显示文摘Colorectal endoscopic submucosal dissection(ESD) is considered one of the most challenging endoscopic procedures for novice endoscopists. When compared with the stomach, the colon and rectum have a narrower tubular lumen, greater angulation at the flexures, and a thinner muscle layer. These factors make endoscopic control and maneuverability difficult. ESD of the colorectum was considered more difficult than gastric and esophageal ESD. However, with learning from the experts, practicing, and selecting an appropriate technique,most of colorectal ESD could be performed successfully. Nevertheless, some colorectal locations are extremely specialized either from unique anatomy or given unstable scope position. Accordingly, the objective of this review was to provide endoscopists with an overview of the techniques and outcomes associated with ESD at these special colorectal locations. ESD at the discussed special locations of the ileo-colo-rectum was found to be feasible, and outcomes were comparable to those of ESD performed in non-special locations of the ileocolo-rectum. Practice for skill improvement and awareness of the unique characteristics of each special location is the key to performing successful ESD. | Uayporn Kaosombatwattana Takeshi Yamamura Masanao Nakamura Yoshiki Hirooka Hidemi Goto | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，4： | 3 |
| 18 | Diffuse gastroduodenitis and pouchitis associated with ulcerative colitis显示文摘We experienced a very rare case of ulcerative colitis (UC) accompanied with analogous lesions in the stomach, duodenum, and ileal J -pouch. Ileal J-pouch anal anastomosis was performed on a 29-year old woman in 1996. Six years later, she was admitted again to our hospital because of epigastralgia, nausea, watery diarrhea and low fever. Based on the results of endoscopic examination, we diagnosed it as pouchitis. Moreover, on hypotonic duodenography, expansion of the duodenal bulb and the descending portion were poor. Kerckring folds disappeared with typical lead-pipe appearance. The pathogenesis of the gastric and duodenal lesion in this patient was similar to that of the colonic lesions of UC. For the gastroduodenal lesions in this patient, symptomatic remission was obtained following administration of crushed mesalazine tablets (1500 mg/d) for 14 d with continuous administration of omeprazole. Firstly we used ciprofloxacin to treat pouchitis. On the fifth day, she got a fever because of catheter infection. In the catheter culture, methicillin-resistant Staphylococcus aureus (MRSA) was detected. Therefore we changed ciprofloxacin to vancomycin hydrochloride (Vancomycin?). Vancomycin was very effective, and the stool frequency dramatically improved in three days. Now she continues to take mesalazine, but her condition is stable and there has been no recurrence of pouchitis. | Hiroki Ikeuchi Kazutoshi Hori Takashi Nishigami Hiroki Nakano Motoi Uchino Mitsuhiro Nakamura Nobuaki Kaibe Masafumi Noda Hidenori Yanagi Takehira Yamamura | 2006 | World Journal of Gastroenterology2006，12，36： | 3 |
| 19 | Early gastric cancer frequently has high expression of KKLC-1, a cancer-testis antigen显示文摘AIM To assess cancer-testis antigens(CTAs) expression in gastric cancer patients and examined their associations with clinicopathological factors.METHODS Eighty-three gastric cancer patients were evaluated in this study. Gastric cancer specimens were evaluated for the gene expression of CTAs, Kitakyushu lung cancer antigen-1(KK-LC-1), melanoma antigen(MAGE)-A1, MAGE-A3 and New York esophageal cancer-1(NYESO-1), by reverse transcription PCR. Clinicopathological background information, such as gender, age, tumor size, macroscopic type, tumor histology, depth of invasion, lymph node metastasis, lymphatic invasion, venous invasion, and pathological stage, was obtained. Statistical comparisons between the expression of each CTA and each clinicopathological background were performed using the χ2 test. RESULTS The expression rates of KK-LC-1, MAGE-A1, MAGE-A3, and NY-ESO-1 were 79.5%, 32.5%, 39.8%, and 15.7%, respectively. In early stage gastric cancer specimens, the expression of KK-LC-1 was 79.4%, which is comparable to the 79.6% observed in advanced stage specimens. The expression of KK-LC-1 was not significantly associated with clinicopathological factors, while there were considerable differences in the expression rates of MAGE-A1 and MAGE-A3 with vs without lymphatic invasion(MAGE-A1, 39.3% vs 13.6%, P = 0.034; MAGE-A3, 47.5% vs 18.2%, P = 0.022) and/or vascular invasion(MAGE-A1, 41.5% vs 16.7%, P = 0.028; MAGE-A3, 49.1% vs 23.3%, P = 0.035) and, particularly, MAGE-A3, in patients with early vs advanced stage(36.5% vs 49.0%, P = 0.044), respectively. Patients expressing MAGE-A3 and NYESO-1 were older than those not expressing MAGE-A3 and NY-ESO-1(MAGE-A3, 73.7 ± 7.1 vs 67.4 ± 12.3, P = 0.009; NY-ESO-1, 75.5 ± 7.2 vs 68.8 ± 11.2, P = 0.042). CONCLUSION The KK-LC-1 expression rate was high even in patients with stage I cancer, suggesting that KK-LC-1 is a useful biomarker for early diagnosis of gastric cancer. | Nobue Futawatari Takashi Fukuyama Rui Yamamura Akiko Shida Yoshihito Takahashi Yatsushi Nishi Yoshinobu Ichiki Noritada Kobayashi Hitoshi Yamazaki Masahiko Watanabe | 2017 | World Journal of Gastroenterology2017，23，46： | 3 |
