| 1 | 日本东北9.0级地震的同震与震后滑动显示文摘大部分强震都发生在海沟,那里是海洋板块向大陆板块俯冲的地方。大量矩震级MW9.0以上的地震发生在若干区域,包括智利,阿拉斯加,堪察加半岛和苏门答腊岛等。位于太平洋板块俯冲鄂霍茨克板块的日本海沟,历史记载上没有发生过MW9.0地震,除了至今震级还有争议的公元869年Jogan大地震[1](可能超过MW9.0)。然而,根据最新的大地测量资料估算的应变积累速率比已发生的板块间地震的平均释放速率要高[2~6]。这一发现又引发了这样的疑问:这些区域如何释放积累的应变。2011年3月11日发生的逆冲型MW9.0强震(下文中均称为日本东北大地震),撕裂了日本东北部的太平洋海岸板块边界。我们报道根据GPS网络监测到的地表位移确定的同震与震后滑动特征。同震滑移区域沿日本海沟方向长约400 km,与震前闭锁区域基本吻合[4]。震后滑动不仅覆盖了同震滑移区域,而且扩展到了其邻区,甚至其影响已经达到100 km深度区域,引起2011年3月25日的MW8.3地震。由于东北地震释放了积累数百年的应变,之前提到的应变积累与释放不平衡的问题可能得到部分解释。这次东北地震同时也提醒我们,即使在过去没有发生过强震的其它海沟地区,也有发生MW9.0强震的潜在危险。因此,利用空间对地形变观测技术监测应变积累,以确定强震潜在危险区是非常重要的。 | Shinzaburo Ozawa Takuya Nishimura Hisashi Suito Tomokazu Kobayashi Mikio Tobita Tetsuro Imakiire 张慧(译) 焦明若(校) | 2011 | 华南地震2011，31，3： | 30 |
| 2 | Prognosis of metastatic splenic hilum lymph node in patients with gastric cancer after total gastrectomy and splenectomy显示文摘AIM:To clarify the significance of combined resection of the spleen to dissect the No.10 lymph node(LN). METHODS:We studied 191 patients who had undergone total gastrectomy with splenectomy,excluding non-curative cases,resection of multiple gastric cancer, and those with remnant stomach cancer.Various clinico-pathological factors were evaluated for any independent contributions to No.10 LN metastasis,usingχ 2 test. Significant factors were extracted for further analysis, carried out using a logistic regression method.Furthermore,lymph node metastasis was evaluated for any independent contribution to No.10 LN metastasis,using the same methods.The cumulative survival rate was calculated using the Kaplan-Meier method.The significance of any difference between the survival curves was determined using the Cox-Mantel test,and any difference was considered significant at the 5%level. RESULTS:From the variables considered to be potentially associated with No.10 LN metastasis,age, depth,invasion of lymph vessel,N factor,the numberof lymph node metastasis,Stage,the number of sites, and location were found to differ significantly between those with metastasis(the Positive Group)and those without(the Negative Group).A logistic regression analysis showed that the localization and Stage were significant parameters for No.10 LN metastasis.There was no case located on the lesser curvature in the Posi-tive Group.The numbers of No.2,No.3,No.4sa,No. 4sb,No.4d,No.7,and No.11 LN metastasis were each found to differ significantly between the Positive Group and the Negative Group.A logistic regression analysis showed that No.4sa,No.4sb,and No.11 LN metastasis were each a significant parameter for No.10 LN metastasis.There was no significant difference in survival curves between the Positive Group and the Negative Group. CONCLUSION:Splenectomy should be performed to dissect No.10 LN for cases which have No.4sa,No. 4sb or No.11 LN metastasis.However,in cases where the tumor is located on the lesser curvature,splenectomy can be omitted. | Keishiro Aoyagi Kikuo Kouhuji Motoshi Miyagi Takuya Imaizumi Junya Kizaki Kazuo Shirouzu | 2010 | World Journal of Hepatology2010，2，2： | 26 |
| 3 | Evaluation of the effect of pyrrolidine dithiocarbamate in suppressing inflammation in mice with dextran sodium sulfate-induced colitis显示文摘AIM: To evaluate the effect of pyrrolidine dithio- carbamate (PDTC; an NF-κB inhibitor) administered at low (50 mg/kg) and high (100 mg/kg) doses in suppressing colitis in mice with dextran sodium sulfate (DSS)-induced colitis. METHODS: Mice were divided into a DSS-untreated group (normal group), DSS-treated control group, DSS+PDTC-treated groupⅠ(low-dose group), and DSS+PDTC-treated groupⅡ (high-dose group). In each group, the disease activity index score (DAI score), intestinal length, histological score, and the levels of activated NF-κB and inflammatory cytokines (IL-1β and TNF-α) in tissue were measured. RESULTS: The DSS+PDTC-treated groupⅡ exhibited suppression of shortening of intestinal length and reduction of DAI score. Activated NF-κB level and IL-1β and TNF-α levels were significantly lower in DSS+PDTC- treated groupⅡ. CONCLUSION: These findings suggest that PDTC is useful for the treatment of ulcerative colitis. | Ichiro Hirata Shingo Yasumoto Ken Toshina Takuya Inoue Takashi Nishikawa Naoko Murano Mitsuyuki Murano Fang-Yu Wang Ken-ichi Katsu | 2007 | World Journal of Gastroenterology2007，13，11： | 20 |
| 4 | Improving recognition of hepatic perivascular epithelioid cell tumor:Case report and literature review显示文摘A 58-year-old man presented with the chief complaint of abdominal bloating and was incidentally found to have a liver tumor.As diagnostic imaging studies could not rule out malignancy,the patient underwent partial resection of segment 3 of the liver.The lesion pathologically showed eosinophilic proliferation,in addition to immunohistochemical positivity for human melanoma black 45 and Melan-A,thereby leading to the diagnosis of a hepatic perivascular epithelioid cell tumor(PEComa).A PEComa arising from the liver is relatively rare.Moreover,the name ‘PEComa' has not yet been widely recognized,and the same disease entity has been called epithelioid angiomyolipoma(EAML),further diminishing the recognition of PEComa.In addition,PEComa imaging findings mimic those of malignant liver tumors,and clinically,this tumor tends to enlarge.Therefore,a PEComa is difficult to diagnose.We conducted a systematic review of PEComa and EAML cases and discuss the results,including findings useful for differentiating perivascular epithelioid cell tumors from malignant liver tumors. | Toshiya Maebayashi Katsumi Abe Takuya Aizawa Masakuni Sakaguchi Naoya Ishibashi Osamu Abe Tadatoshi Takayama Hisashi Nakayama Shunichi Matsuoka Kazushige Nirei Hitomi Nakamura Masahiro Ogawa Masahiko Sugitani | 2015 | World Journal of Gastroenterology2015，21，17： | 20 |
| 5 | Treatment strategy for gastric non-invasive intraepithelial neoplasia diagnosed by endoscopic biopsy显示文摘Treatment strategies,whether as follow-up or'total incisional biopsy'for gastric noninvasive intraepithelial neoplasia diagnosed by examination of an endoscopic forceps biopsy specimen,are controversial due to problems associated with the diagnostic accuracy of endoscopic forceps biopsy and questions about the safety and efficacy of endoscopic treatment.Based on the histological findings of the biopsy specimen,it is difficult to differentiate between reactive or regenerative changes,inflammation and neoplastic changes,intraepithelial and invasive tumors.Therefore,gastric neoplasia diagnosed as noninvasive intraepithelial often develop into invasive carcinoma during follow-up.Recent advances in endoscopic modalities and treatment devices,such as image-enhanced endoscopy and highfrequency generators,may make endoscopic treatment,such as endoscopic submucosal dissection(ESD),a therapeutic option for gastric intraepithelial neoplasia,including low-grade neoplasms.Future studies are required to evaluate whether ESD is a valid strategy for gastric intraepithelial neoplasm with regard to safety and cost effectiveness. | Tsutomu Nishida Shusaku Tsutsui Motohiko Kato Takuya Inoue Shunsuke Yamamoto Yoshito Hayashi Tomofumi Akasaka Takuya Yamada Shinichiro Shinzaki Hideki Iijima Masahiko Tsujii Tetsuo Takehara | 2011 | World Journal of Gastrointestinal Pathophysiology2011，2，6： | 18 |
| 6 | Clinical outcomes and risk factors for perforation in gastric endoscopic submucosal dissection: A prospective pilot study显示文摘AIM: To evaluate clinical outcomes and risk factors for endoscopic perforation during endoscopic submucosal dissection (ESD) in a prospective study. METHODS: We investigated the clinical outcomes and risk factors for the development of perforation in 98 consecutive gastric neoplasms undergoing ESD regarding. Demographic and clinical parameters including patient-, tumor-, and treatment-related factors, clinical parameters, and duration of hospital stay were analyzed for risk factors for perforation. In subgroup analysis, we also compared the clinical outcomes between perforation and 'silent' free air without endoscopically visible perforation detected only by computed tomography.RESULTS: Perforation was identified in 8.2% of patients. All patients were managed conservatively by the administration of antibiotics. The mean procedure time was significantly longer in patients with endoscopic perforation than in those without. According to the receiver-operating characteristic analysis, the resulting cutoff value of the procedure time for perforation was 115 min (87.5% sensitivity, 56.7% specificity). Prolonged procedure time (≥ 115 min) was associated with an increased risk of perforation (odds ratio 9.15; 95%CI: 1.08-77.54; P = 0.04). Following ESD, body temperature and C-reactive protein level were significantly higher in patients with perforation than in those without (P = 0.02), whereas there was no difference between these patient groups on the starting day of oral intake or of hospitalization. In subgroup analysis, the post-ESD clinical course was not different between endoscopic perforation and silent free air. CONCLUSION: Only prolonged procedure time (≥ 115 min) was significantly associated with perforation. The clinical outcomes of perforation are favorable and are comparable to those of patients with or without silent free air. | Jiro Watari Toshihiko Tomita Fumihiko Toyoshima Jun Sakurai Takashi Kondo Haruki Asano Takahisa Yamasaki Takuya Okugawa Hisatomo Ikehara Tadayuki Oshima Hirokazu Fukui Hiroto Miwa | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，6： | 17 |
| 7 | Combined assessment of myocardial damage and electrical disturbance in chronic heart failure显示文摘AIM To investigate feasibility of combined assessment of biochemical and electrophysiological myocardial impairment markers risk-stratifying patients with chronic heart failure(CHF). METHODS Serum levels of heart-type fatty acid binding protein(H-FABP) as a marker of ongoing myocardial damage and QRS duration on electrocardiogram were measured at admission in 322 consecutive patients with CHF. A prolonged QRS duration was defined as 120 ms or longer. The cut-off value for H-FABP level(4.5 ng/mL) was determined from a previous study. Patients were prospectively followed during a median follow up period of 534 d. The primary endpoint was cardiac deaths and rehospitalization for worsening CHF.RESULTS There were 117 primary events, including 27 cardiac deaths and 90 rehospitalizations. Patients were stratified into four groups according to H-FABP level and QRS duration(≥ 120 ms). Multivariate analysis demonstrated that high H-FABP levels [hazard ratio(HR) = 1.745, P = 0.021] and QRS prolongation(HR1.612, P = 0.0258) were independent predictors of cardiac events. Kaplan-Meier analysis demonstrated that the combination of high H-FABP levels and QRS prolongation could be used to reliably stratify patients at high risk for cardiac events(log rank test P < 0.0001).CONCLUSION Combined assessment of myocardial damage and electrical disturbance can be used to risk-stratify patients with CHF. | Shinpei Kadowaki Tetsu Watanabe Yoichiro Otaki Taro Narumi Yuki Honda Hiroki Takahashi Takanori Arimoto Tetsuro Shishido Takuya Miyamoto Isao Kubota | 2017 | World Journal of Cardiology2017，9，5： | 14 |
| 8 | 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 |
| 9 | DOG1 is useful for diagnosis of KIT-negative gastrointestinal stromal tumor of stomach显示文摘Approximately 80%-95%of gastrointestinal stromal tumors(GISTs)show positive staining for KIT,while the other 5%-20%show negative staining.If the tumor is negative for KIT,but is positive for CD34,a histological diagnosis is possible.However,if the tumor is negative for KIT,CD34,S-100,and SMA,a definitive diagnosis is often challenging.Recently,Discovered on GIST-1(DOG1)has received considerable attention as a useful molecule for the diagnosis of GIST.DOG1,a membrane channel protein,is known to be overexpressed in GIST.Because the sensitivity and specificity of DOG1 are higher than those of KIT,positive staining for DOG1has been reported,even in KIT-negative GISTs.KITnegative GISTs most commonly arise in the stomach and are mainly characterized by epithelioid features histologically.We describe our experience with a rare case of a KIT-negative GIST of the stomach that was diagnosed by positive immunohistochemical staining for DOG1 in a patient who presented with severe anemia.Our findings suggest that immunohistochemical staining for DOG1,in addition to gene analysis,is useful for the diagnosis of KIT-negative tumors that are suspected to be GISTs. | Takuya Wada Satoshi Tanabe Kenji Ishido Katsuhiko Higuchi Tohru Sasaki Chikatoshi Katada Mizutomo Azuma Akira Naruke Myunguchul Kim Wasaburo Koizumi Tetsuo Mikami | 2013 | World Journal of Gastroenterology2013，19，47： | 11 |
| 10 | Treatment strategies for advanced hepatocellular carcinoma:Sorafenib vs hepatic arterial infusion chemotherapy显示文摘Sorafenib is used worldwide as a first-line standardsystemic agent for advanced hepatocellular carcinoma(HCC) on the basis of the results of two large-scale Phase Ⅲ trials. Conversely,hepatic arterial infusion chemotherapy(HAIC) is one of the most recommended treatments in Japan. Although there have been no randomized controlled trials comparing sorafenib with HAIC,several retrospective analyses have shown no significant differences in survival between the two therapies. Outcomes are favorable for HCC patients exhibiting macroscopic vascular invasion when treated with HAIC rather than sorafenib,whereas in HCC patients exhibiting extrahepatic spread or resistance to transcatheter arterial chemoembolization,good outcomes are achieved by treatment with sorafenib rather than HAIC. Additionally,sorafenib is generally used to treat patients with Child-Pugh A,while HAIC is indicated for those with either Child-Pugh A or B. Based on these findings,we reviewed treatment strategies for advanced HCC. We propose that sorafenib might be used as a first-line treatment for advanced HCC patients without macroscopic vascular invasion or Child-Pugh A,while HAIC is recommended for those with macroscopic vascular invasion or Child-Pugh A or B. Additional research is required to determine the best second-line treatment for HAIC non-responders with Child-Pugh B through future clinical trials. | Issei Saeki Takahiro Yamasaki Masaki Maeda Takuro Hisanaga Takuya Iwamoto Koichi Fujisawa Toshihiko Matsumoto Isao Hidaka Yoshio Marumoto Tsuyoshi Ishikawa Naoki Yamamoto Yutaka Suehiro Taro Takami Isao Sakaida | 2018 | World Journal of Hepatology2018，10，9： | 10 |
| 11 | Paraneoplastic syndromes associated with lung cancer显示文摘Paraneoplastic syndromes are signs or symptoms that occur as a result of organ or tissue damage at locations remote from the site of the primary tumor or metastases. Paraneoplastic syndromes associated with lung cancer can impair various organ functions and include neurologic, endocrine, dermatologic, rheumatologic, hematologic, and ophthalmological syndromes, as well as glomerulopathy and coagulopathy(Trousseau's syndrome). The histological type of lung cancer is generally dependent on the associated syndrome, the two most common of which are humoral hypercalcemia of malignancy in squamous cell carcinoma and the syndrome of inappropriate antidiuretic hormone secretion in small cell lung cancer. The symptoms often precede the diagnosis of the associated lung cancer, especially when the symptoms are neurologic or dermatologic. The proposed mechanisms of paraneoplastic processes include the aberrant release of humoral mediators, such as hormones and hormone-like peptides, cyto-kines, and antibodies. Treating the underlying cancer is generally the most effective therapy for paraneoplastic syndromes, and treatment soon after symptom onset appears to offer the best potential for symptom improvement. In this article, we review the diagnosis, potential mechanisms, and treatments of a wide variety of paraneoplastic syndromes associated with lung cancer. | Nobuhiro Kanaji Naoki Watanabe Nobuyuki Kita Shuji Bandoh Akira Tadokoro Tomoya Ishii Hiroaki Dobashi Takuya Matsunaga | 2014 | World Journal of Clinical Oncology2014，5，3： | 10 |
| 12 | An easier method for performing a pancreaticojejunostomy for the soft pancreas using a fast-absorbable suture显示文摘AIM: To clarify the usefulness of a new method for performing a pancreaticojejunostomy by using a fast-absorbable suture material irradiated polyglactin 910, and a temporary stent tube for a narrow pancreatic duct with a soft pancreatic texture.METHODS: Among 63 consecutive patients with soft pancreas undergoing a pancreaticoduodenectomy from 2003 to 2006, 35 patients were treated with a new reconstructive method. Briefly, after the pancreatic transaction, a stent tube was inserted into the lumen of the pancreatic duct and ligated with it by a fast-absorbable suture. Another tip of the stent tube was introduced into the intestinal lumen at the jejunal limb, where a purse-string suture was made by another fast-absorbable suture to roughly fix the tube. The pancreaticojejunostomy was completed by ligating two fast-absorbable sutures to approximate the ductal end and the jejunal mucosa, and by adding a rough anastomosis between the pancreatic parenchyma and the seromuscular layer of the jejunum. The initial surgical results with this method were retrospectively compared with those of the 28 patients treated with conventional duct-to-mucosa anastomosis.RESULTS: The incidences of postoperative morbidity including pancreatic fistula were comparable between the two groups (new; 3%-17% vs conventional; 7%-14% according to the definitions). There was no mortality and re-admission. Late complications were also rarely seen.CONCLUSION: A pancreaticojejunostomy using an irradiated polyglactin 910 suture material and a temporary stent is easy to perform and is feasible even in cases with a narrow pancreatic duct and a normal soft pancreas. | Kenichi Hakamada Shunji Narumi Yoshikazu Toyoki Masaki Nara Kenosuke Ishido Takuya Miura Norihito Kubo Mutsuo Sasaki | 2008 | World Journal of Gastroenterology2008，14，7： | 9 |
| 13 | Clinical outcomes of ampullary neoplasms in resected margin positive or uncertain cases after endoscopic papillectomy显示文摘BACKGROUND Endoscopic papillectomy(EP) for benign ampullary neoplasms could be a lessinvasive alternative to pancreatoduodenectomy(PD). There are some problems and limitations with EP. The post-EP resection margins of ampullary tumors are often positive or uncertain because of the burning effect of EP. The clinical outcomes of resected margin positive or uncertain cases after EP remain unknown.AIM To investigate the clinical outcomes of resected margin positive or uncertain cases after EP.METHODS Between January 2007 and October 2018, all patients with ampullary tumors who underwent EP at Kobe University Hospital were included in this study. The indications for EP were as follows: adenoma, as determined by preoperative endoscopic biopsy, without bile/pancreatic duct extension, according to endoscopic ultrasound or intraductal ultrasound. The clinical outcomes of resected margin positive or uncertain cases after EP were retrospectively investigated.RESULTS Of the 45 patients, 29 were male, and 16 were female. The mean age of the patients was 65 years old. Forty-one patients(89.5%) underwent en bloc resection,and 4 patients(10.5%) underwent piecemeal resection. After EP, 33 tumors were histopathologically diagnosed as adenoma, and 12 were diagnosed as adenocarcinoma. The resected margins were positive or uncertain in 24 patients(53.3%). Of these cases, 15 and 9 were diagnosed as adenoma and adenocarcinoma, respectively. Follow-up observation was selected for all adenomas and 5 adenocarcinomas. In the remaining 4 adenocarcinoma cases,additional PD was performed. Additional PD was performed in 4 cases, and residual carcinoma was found after the additional PD in 1 of these cases. In the follow-up period, local tumor recurrence was detected in 3 cases. Two of these cases involved primary EP-diagnosed adenoma. The recurrent tumors were also adenomas detected by biopsy. The remaining case involved primary EPdiagnosed adenocarcinoma. The recurrent tumor was also an adenocarcinoma.All of the recurrent tumors were successfully treated with argon plasma coagulation(APC). There was no local or lymph node recurrence after the APC.The post-APC follow-up periods lasted for 57.1 to 133.8 mo. No ampullary tumor-related deaths occurred in all patients.CONCLUSION Resected margin positive or uncertain cases after EP could be managed by endoscopic treatment including APC, even in cases of adenocarcinoma. EP could become an effective less-invasive first-line treatment for early stage ampullary tumors. | Arata Sakai Masahiro Tsujimae Atsuhiro Masuda Takao Iemoto Shigeto Ashina Kohei Yamakawa Takeshi Tanaka Shunta Tanaka Yasutaka Yamada Ryota Nakano Yu Sato Manabu Kurosawa Takuya Ikegawa Seiji Fujigaki Takashi Kobayashi Hideyuki Shiomi Yoshifumi Arisaka Tomoo Itoh Yuzo Kodama | 2019 | World Journal of Gastroenterology2019，25，11： | 9 |
| 14 | Molecular, Functional, and Structural Imaging of Major Depressive Disorder显示文摘Major depressive disorder(MDD) is a significant cause of morbidity and mortality worldwide,correlating with genetic susceptibility and environmental risk factors.Molecular,functional,and structural imaging approaches have been increasingly used to detect neurobiological changes,analyze neurochemical correlates,and parse pathophysiological mechanisms underlying MDD.We reviewed recent neuroimaging publications on MDD in terms of molecular,functional,and structural alterations as detected mainly by magnetic resonance imaging(MRI) and positron emission tomography.Altered structure and function of brain regions involved in the cognitive control of affective state have been demonstrated.An abnormal default mode network,as revealed by resting-state functional MRI,is likely associated with aberrant metabolicand serotonergic function revealed by radionuclide imaging.Further multi-modal investigations are essential to clarify the characteristics of the cortical network and serotonergic system associated with behavioral and genetic variations in MDD. | Kai Zhang Yunqi Zhu Yuankai Zhu Shuang Wu Hao Liu Wei Zhang Caiyun Xu Hong Zhang Takuya Hayashi Mei Tian | 2016 | Neuroscience Bulletin2016，32，3： | 9 |
| 15 | Endoscopic ultrasound-guided fine needle aspiration in the differentiation of type 1 and type 2 autoimmune pancreatitis显示文摘AIM:To investigate the usefulness of endoscopic ultrasound-guided fine needle aspiration(EUS-FNA) in the differentiation of autoimmune pancreatitis(AIP).METHODS:We retrospectively reviewed 47 of 56 AIP patients who underwent EUS-FNA and met the Asian diagnostic criteria.On 47 EUS-FNA specimens,we evaluated the presence of adequate material and characteristic features of lymphoplasmacytic sclerosing pancreatitis(LPSP) and idiopathic duct-centric pancreatitis(IDCP) mentioned in the International Consensus Diagnostic Criteria and examined if these findings make a contribution to the differential diagnosis of type 1 and type 2 AIP.A disposable 22-gauge needle was used for EUS-FNA.RESULTS:Adequate specimens including pancreatic tissue for differentiating AIP from cancer were obtained from 43 of 47 patients who underwent EUSFNA.EUS-FNA was performed from the pancreatic head in 21 cases,which is known to be technically difficult when performed by core biopsy;there was no significant difference in the results compared with pancreatic body-tail.Nine of 47 patients met level 1 findings of LPSP and 5 patients met level 2 findings of LPSP.No one met level 1 findings of IDCP,but 3 patients met level 2 findings of IDCP.Of 10 seronegative cases,2 cases were diagnosed with 'definitive type 1 AIP',and 3 cases were diagnosed with 'probable type 2 AIP' when considering both the level 2 histological findings and response to steroids.CONCLUSION:EUS-FNA is useful in the differentiation of type 1 and type 2 AIP,particularly in seronegative cases. | Takuya Ishikawa Akihiro Itoh Hiroki Kawashima Eizaburo Ohno Hirosh Matsubara Yuya Itoh Yosuke Nakamura Takeshi Hiramatsu Masanao Nakamura Ryoji Miyahara Naoki Ohmiya Hidemi Goto Yoshiki Hirooka | 2012 | World Journal of Gastroenterology2012，18，29： | 8 |
| 16 | What types of early gastric cancer are indicated for endoscopic ultrasonography staging of invasion depth?显示文摘AIM To clarify the diagnostic efficacy and limitations of endoscopic ultrasonography(EUS) and the characteristics of early gastric cancers(EGCs) that are indications for EUS-based assessment of cancer invasion depth.METHODS We retrospectively investigated the cases of 153 EGC patients who underwent conventional endoscopy(CE) and EUS(20 MHz) before treatment.RESULTS We found that 13.7% were 'inconclusive' cases with low-quality EUS images, including all nine of the cases with protruded(0-I)-type EGCs. There was no significant difference in the diagnostic accuracybetween CE and EUS. Two significant independent risk factors for misdiagnosis by EUS were identified-ulcer scarring [UL(+); odds ratio(OR) = 4.49, P = 0.003] and non-indication criteria for endoscopic resection(ER)(OR = 3.02, P = 0.03). In the subgroup analysis, 23.1% of the differentiated-type cancers exhibiting SM massive invasion(SM2) invasion(submucosal invasion ≥ 500 μm) by CE were correctly diagnosed by EUS, and 23.1% of the undifferentiated-type EGCs meeting the expanded-indication criteria for ER were correctly diagnosed by EUS.CONCLUSION There is no need to perform EUS for UL(+) EGCs or 0-I-type EGCs, but EUS may enhance the pretreatment staging of differentiated-type EGCs with SM2 invasion without UL or undifferentiated-type EGCs revealed by CE as meeting the expanded-indication criteria for ER. | Jiro Watari Shigemitsu Ueyama Toshihiko Tomita Hisatomo Ikehara Kazutoshi Hori Ken Hara Takahisa Yamasaki Takuya Okugawa Takashi Kondo Tomoaki Kono Katsuyuki Tozawa Tadayuki Oshima Hirokazu Fukui Hiroto Miwa | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，16： | 8 |
| 17 | Hybrid Rubisco with Complete Replacement of Rice Rubisco Small Subunits by Sorghum Counterparts Confers C4 Plant-like High Catalytic Activity显示文摘Photosynthetic rate at the present atmospheric condition is limited by the CO2-fixing enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase(Rubisco)because of its extremely low catalytic rate(kcat)and poor affinity for C02(Kc)and specificity for CO2(Sc/O).Rubisco in C4 plants generally shows higher k cat than that in C3 plants.Rubisco consists of eight large subunits and eight small subunits(RbcS).Previously,the chimeric incorporation of sorghum C4-type RbcS significantly increased the k cat of Rubisco in a C3 plant,rice.In this study,we knocked out rice RbcS multigene family using the CRISPR-Cas9 technology and completely replaced rice RbcS with sorghum RbcS in rice Rubisco.Obtained hybrid Rubisco showed almost C4 plant-like catalytic properties,i.e.,higher kcai,higher Kc,and lower Sc/O.Transgenic lines expressing the hybrid Rubisco accumulated reduced levels of Rubisco,whereas they showed slightly but significantly higher photosynthetic capacity and similar biomass production under high C 02 condition compared with wild-type rice.High-resolution crystal structural analysis of the wild-type Rubisco and hybrid Rubisco revealed the structural differences around the central pore of Rubisco and the pC-pD hairpin in RbcS.We propose that such differences,particularly in the pC-pD hairpin,may impact the flexibility of Rubisco catalytic site and change its catalytic properties. | Hiroyoshi Matsumura Keita Shiomi Akito Yamamoto Yuri Taketani Noriyuki Kobayashi Takuya Yoshizawa Shun-ichi Tanaka Hiroki Yoshikawa Masaki Endo Hiroshi Fukayama | 2020 | Molecular Plant2020，13，11： | 8 |
| 18 | Progress in researches about focal adhesion kinase in gastrointestinal tract显示文摘Focal adhesion kinase(FAK)is a 125-kDa non-receptor protein tyrosine.Growth factors or the clustering of integrins facilitate the rapid phosphorylation of FAK at Tyr-397 and this in turn recruits Src-family protein tyrosine kinases,resulting in the phosphorylation of Tyr-576 and Tyr-577 in the FAK activation loop and full catalytic FAK activation.FAK plays a critical role in the biological processes of normal and cancer cells including the gastrointestinal tract.FAK also plays an important role in the restitution,cell survival and apoptosis and carcinogenesis of the gastrointestinal tract.FAK is over-expressed in cancer cells and its over-expression and elevated activities are associated with motility and invasion of cancer cells.FAK has been proposed as a potential target in cancer therapy.Small molecule inhibitors effectively inhibit the kinase activity of FAK and show a potent inhibitory effect for the proliferation and migration of tumor cells,indicating a high potential for application in cancer therapy. | Hui Fang Hao Yoshio Naomoto Xiao-Hong Bao Nobuyuki Watanabe Kazufumi Sakurama Kazuhiro Noma Yasuko Tomono Takuya Fukazawa Yasuhiro Shirakawa Tomoki Yamatsuji Junji Matsuoka Munenori Takaoka | 2009 | World Journal of Gastroenterology2009，15，47： | 8 |
| 19 | Change in arterial tumor perfusion is an early biomarker of lenvatinib efficacy in patients with unresectable hepatocellular carcinoma显示文摘BACKGROUND Lenvatinib is one of the first-line tyrosine kinase inhibitors used for unresectable hepatocellular carcinoma(HCC). In the present study, we evaluated the potential of early changes in the time-intensity curve(TIC) of arterial phase on contrastenhanced ultrasound(CEUS) as early imaging biomarkers of lenvatinib efficacy.AIM To evaluate the potential of the early changes in the TIC of CEUS as early imaging biomarkers of lenvatinib efficacy in patients with unresectable HCC.METHODS We analyzed 20 consecutive patients with unresectable HCC treated with lenvatinib from March to November 2018. Tumor response at 8 wk was assessed by computed tomography using the modified Response Evaluation Criteria in Solid Tumors(m RECIST). CEUS was performed at baseline before treatment(Day 0) and on day 7(Day 7), and the images were analyzed in the arterial phase for 20 seconds after the contrast agent arrived at the target tumor. Three perfusion parameters were extracted from the TICs: the slope of wash-in(Slope),time to peak(TTP) intensity, and the total area under the curve(AUC) during wash-in. The rate of change in the TIC parameters between Day 0 and Day 7 was compared between treatment responders and non-responders based on m RECIST.RESULTS The rate of change for all TIC parameters showed significant differences between the responders(n = 9) and non-responders(n = 11)(Slope, P = 0.025; TTP, P =0.004; and AUC, P = 0.0003). The area under the receiver operating curve values for slope, TTP, and AUC for the prediction of responders were 0.805, 0.869, and0.939, respectively.CONCLUSION CEUS may be useful for the early prediction of tumor response to lenvatinib therapy in patients with unresectable HCC. | Hidekatsu Kuorda Tamami Abe Yudai Fujiwara Takuya Okamoto Miki Yonezawa Hiroki Sato Kei Endo Takayoshi Oikawa Kei Sawara Yasuhiro Takikawa | 2019 | World Journal of Gastroenterology2019，25，19： | 8 |
| 20 | 高强度管线钢及其焊管的性能研究显示文摘目前X80级管线钢管已在大口径输送管线中得到应用,使得对进一步提高管线钢强度(X100~X120级)的需求也更迫切了.使用高强度管线钢目的是拟通过提高管道的输送压力来提高其输送效率和降低铺设管线费用.为将这两点期望变为现实,高强度管线钢管及其焊接热影响区(HAZ)应具备良好的低温韧性和现场焊接(环焊)性能,所以,必须综合应用合理的合金成分设计,超纯净冶炼,控轧、控冷(TMCP)等工艺,改善焊接热影响区工艺等多方面的技术和措施,以得到同时具备高强度、良好的低温韧性和现场焊接性能的管线钢. | Naoshi Ayukawa Yoshio Terada Takuya Hara Hitoshi Asahi | 2005 | 焊管2005，28，2： | 8 |
