2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
3Progression of remnant gastric cancer is associated with duration of follow-up following distal gastrectomy显示文摘AIM: To re-evaluate the recent clinicopathological features of remnant gastric cancer (RGC) and to develop desirable surveillance programs. METHODS: Between 1997 and 2008, 1149 patients underwent gastrectomy for gastric cancer at the Department of Digestive Surgery, Kyoto Prefectural University of Medicine, Japan. Of these, 33 patients underwent gastrectomy with lymphadenectomy for RGC. Regarding the initial gastric disease, there were 19 patients with benign disease and 14 patients with gastric cancer. The hospital records of these patients were reviewed retrospectively. RESULTS: Concerning the initial gastric disease, the RGC group following gastric cancer had a shorter interval [P < 0.05; gastric cancer vs benign disease: 12 (2-22) vs 30 (4-51) years] and were more frequently reconstructed by Billroth-Ⅰ procedure than those following benign lesions (P < 0.001). Regarding reconstruction, RGC following Billroth-Ⅱ reconstruction showed a longer interval between surgical procedures [P < 0.001; Billroth-Ⅱ vs Billroth-Ⅰ: 32 (5-51) vs 12 (2-36) years] and tumors were more frequently associated with benign disease (P < 0.001) than those following Billroth-Ⅰ reconstruction. In tumor location of RGC, after Billroth-Ⅰ reconstruction, RGC occurred more frequently near the suture line and remnant gastric wall. After Billroth-Ⅱ reconstruction, RGC occurred more frequently at the anastomotic site. The duration of follow-up was significantly associated with the stage of RGC (P < 0.05). Patients diagnosed with early stage RGC such as stage Ⅰ-Ⅱ tended to have been followed up almost every second year. CONCLUSION: Meticulous follow-up examination and early detection of RGC might lead to a better prognosis. Based on the initial gastric disease and the procedure of reconstruction, an appropriate follow-up interval and programs might enable early detection of RGC.Shuhei Komatsu Daisuke Ichikawa Kazuma Okamoto Daito Ikoma Masahiro Tsujiura Yukihisa Nishimura Yasutoshi Murayama Atsushi Shiozaki Hisashi Ikoma Yoshiaki Kuriu Masayoshi Nakanishi Hitoshi Fujiwara Toshiya Ochiai Yukihito Kokuba Eigo Otsuji 2012World Journal of Gastroenterology2012,18,22:25
4Maintenance for healed erosive esophagitis:PhaseⅢcomparison of vonoprazan with lansoprazole显示文摘AIM To compare vonoprazan 10 and 20 mg vs lansoprazole 15 mg as maintenance therapy in healed erosive esophagitis(EE).METHODS A total of 607 patients aged ≥ 20 years, with endoscopically-confirmed healed EE following 8 wk of treatment with vonoprazan 20 mg once daily, were randomized 1:1:1 to receive lansoprazole 15 mg(n = 201), vonoprazan 10 mg(n = 202), or vonoprazan 20 mg(n = 204), once daily. The primary endpoint of the study was the rate of endoscopically-confirmed EE recurrence during a 24-wk maintenance period. The secondary endpoint was the EE recurrence rate at Week 12 during maintenance treatment. Additional efficacy endpoints included the incidence of heartburn and acid reflux, and the EE healing rate 4 wk after the initiation of maintenance treatment. Safety endpoints comprised adverse events(AEs), vital signs, electrocardiogram findings, clinical laboratory results, serum gastrin and pepsinogen Ⅰ/Ⅱ levels, and gastric mucosa histopathology results.RESULTS Rates of EE recurrence during the 24-wk maintenance period were 16.8%, 5.1%, and 2.0% with lansoprazole 15 mg, vonoprazan 10 mg, and vonoprazan 20 mg, respectively. Vonoprazan was shown to be non-inferior to lansoprazole 15 mg(P < 0.0001 for both doses). In a post-hoc analysis, EE recurrence at Week 24 was significantly reduced with vonoprazan at both the 10 mg and the 20 mg dose vs lansoprazole 15 mg(5.1% vs 16.8%, P = 0.0002, and 2.0% vs 16.8%, P < 0.0001, respectively); by contrast, the EE recurrence rate did not differ significantly between the two doses of vonoprazan(P = 0.1090). The safety profiles of vonoprazan 10 and 20 mg were similar to that of lansoprazole 15 mg in patients with healed EE. Treatment-related AEs were reported in 11.4%, 10.4%, and 10.3% of patients in the lansoprazole 15 mg, vonoprazan 10 mg, and vonoprazan 20 mg arms, respectively.CONCLUSION Our findings confirm the non-inferiority of vonoprazan 10 and 20 mg to lansoprazole 15 mg as maintenance therapy for patients with healed EE.Kiyoshi Ashida Katsuhiko Iwakiri Naoki Hiramatsu Yuuichi Sakurai Tetsuharu Hori Kentarou Kudou Akira Nishimura Eiji Umegaki 2018World Journal of Gastroenterology2018,24,14:18
5Prognostic value of KRAS and BRAF mutations in curatively resected colorectal cancer显示文摘AIM: To investigate the prognostic role of KRAS and BRAF mutations after adjustment for microsatellite instability(MSI) status in Japanese colorectal cancer(CRC) population.METHODS: We assessed KRAS and BRAF mutations and MSI status in 813 Japanese patients with curatively resected, stage Ⅰ-Ⅲ CRC and examined associations of these mutations with disease-free survival(DFS) and overall survival(OS) using uni- and multivariate Cox proportional hazards models.RESULTS: KRAS and BRAF mutations were detected in 312(38%) of 812 and 40(5%) of 811 tumors, respectively. KRAS mutations occurred more frequently in females than in males(P = 0.02), while the presence of BRAF mutations was significantly associated with the female gender(P = 0.006), proximal tumor location(P < 0.001), mucinous or poorly differentiated histology(P < 0.001), and MSI-high tumors(P < 0.001). After adjusting for relevant variables, including MSI status, KRAS mutations were associated with poorer DFS(HR = 1.35; 95%CI: 1.03-1.75) and OS(HR = 1.46; 95%CI: 1.09-1.97). BRAF mutations were poor prognostic factors for DFS(HR = 2.20; 95%CI: 1.19-4.06) and OS(HR = 2.30; 95%CI: 1.15-4.71). Neither the BRAF by MSI interaction test nor the KRAS by MSI interaction test yielded statistically significant results for DFS and OS.CONCLUSION: KRAS and BRAF mutations are associated with inferior survival, independent of MSI status, inJapanese patients with curatively resected CRC.Shigenori Kadowaki Miho Kakuta Shuhei Takahashi Akemi Takahashi Yoshiko Arai Yoji Nishimura Toshimasa Yatsuoka Akira Ooki Kensei Yamaguchi Keitaro Matsuo Kei Muro Kiwamu Akagi 2015World Journal of Gastroenterology2015,21,4:14
6Hyperglycemia is a significant prognostic factor of hepatocellular carcinoma after curative therapy显示文摘AIM:To evaluate whether metabolic factors are related to distant recurrence of hepatocellular carcinoma(HCC) and survival after curative treatment.METHODS:This retrospective study included 344 patients whose HCC was treated curatively by radiofrequency ablation(RFA) therapy.The mean age was 67.6 years and the mean observation period was 4.04 years.The etiological background of liver disease was hepatitis B virus infection in 30,hepatitis C virus infection in 278,excessive alcohol drinking in 9,and other in 27 patients.The Child-Pugh classification grade was A(n = 307) or B(n = 37).The number of HCC nodules was one in 260,two in 61,and three in 23 patients.For surveillance of HCC recurrence after curative therapy with RFA,patients were radiologically evaluated every 3 mo.Factors associated with distant recurrence of HCC or survival were studied.RESULTS:Inadequate maintenance of blood glucose in diabetic patients was associated with higher incidence of distant recurrence.The 1-,2-,and 3-year recurrence rates were significantly higher in diabetic patients with inadequate maintenance of blood glucose compared with the others:50.6% vs 26.8%,83.5% vs 54.4%,and 93.8% vs 73.0%,respectively(P = 0.0001).Inadequate maintenance of blood glucose was an independent predictor of distant recurrence [adjusted relative risk 1.97(95%CI,1.33-2.91),(P = 0.0007)] after adjustment for other risk factors,such as number of HCC nodules [2.03(95%CI,1.51-2.73),P < 0.0001] and initial level of serum alpha fetoprotein(AFP) [1.43(95%CI,1.04-1.97),P = 0.028].Obesity was not an independent predictor of recurrence.The incidence of distant recurrence did not differ between diabetic patients with adequate maintenance of blood glucose and non-diabetic patients.Among 232 patients who had HCC recurrence,138 had a second recurrence.The 1-,2-,and 3-year rates of second recurrence were significantly higher in diabetic patients with inadequate maintenance of blood glucose than in the others:9.0% vs 5.9%,53.1% vs 24.3%,and 69.6% vs 42.3%,respectively(P = 0.0021).Inadequate maintenance of blood glucose in diabetic patients [1.99(95%CI,1.23-3.22),P = 0.0049] and presence of multiple HCC nodules [1.53(95%CI,1.06-2.22),P = 0.024] were again significantly associated with second HCC recurrence.Inadequate maintenance of blood glucose in diabetic patients was also a significant predictor of poor survival [2.77(95%CI,1.38-5.57),P = 0.0046] independent of excessive alcohol drinking [6.34(95%CI,1.35-29.7),P = 0.019],initial level of serum AFP [3.40(95%CI,1.88-6.18),P < 0.0001] and Child-Pugh classification grade B [2.24(95%CI,1.12-4.46),P = 0.022].Comparing diabetic patients with inadequate maintenance of blood glucose vs the others,the 1-,2-,and 3-year survival rates were significantly lower in diabetic patients with inadequate maintenance of blood glucose:92% vs 99%,85% vs 96%,and 70% vs 92%,respectively(P = 0.0003).CONCLUSION:Inadequate maintenance of blood glucose in diabetic patients is a significant risk factor for recurrence of HCC and for poor survival after curative RFA therapy.Takanori Hosokawa Masayuki Kurosaki Kaoru Tsuchiya Shuya Matsuda Masaru Muraoka Yuichiro Suzuki Nobuharu Tamaki Yutaka Yasui Toru Nakata Takashi Nishimura Shoko Suzuki Ken Ueda Hiroyuki Nakanishi Jun Itakura Yuka Takahashi Namiki Izumi 2013World Journal of Gastroenterology2013,19,2:12
7西藏南部普莫雍错19 cal ka BP以来高分辨率环境记录显示文摘利用西藏南部普莫雍错深水湖区获取的3.8m长湖芯,对湖芯中25个样品的植物碎屑进行筛选和有机碳同位素测定,在确定植物来源的前提下进行了14C测定,结合表层样品的过剩210Pb衰变计算的沉积速率对整个湖芯的14C测年及其碳库效应进行了系统校正,结果显示该湖芯完整地覆盖了19calkaBP以来的时间尺度.通过对湖芯TOC,IC,粒度和孢粉的分析,发现该湖在16.2calkaBP之前为一个水深较浅的湖泊,尽管温度升高导致冰川开始融化,湖区环境仍然具有冷干的特征;16.2~11.8calkaBP,沉积环境剧烈而频繁的波动,14.2和11.8calkaBP左右的2次冷事件可能是老仙女木和新仙女木事件的反映.11.8calkaBP之后,已经形成了现今状态的深水湖泊,冰川融水的补给使得湖泊水温较低,受到湖泊水体影响的沉积物环境代用指标对温暖条件的响应并不明显.通过普莫雍错湖与西藏南部相同时代的不同湖泊沉积物记录的比较,发现末次冰消期开始的气候转暖对青藏高原东南部影响更加显著,反映了西南季风自冰消期以后逐渐加强、向高原内部推移的过程,以冰川融水补给为主的湖泊对冷事件的响应更加明显.全新世以来,西南季风对整个西藏南部区域发挥着控制性影响.吕新苗 朱立平 NISHIMURA Mitsugu MORITA Yoshimune WATANABE Takahiro NAKAMURA Toshio 汪勇 2011科学通报2011,56,24:11
8A high-resolution environmental change record since 19 cal ka BP in Pumoyum Co, southern Tibet显示文摘A 380-cm-long sediment core was acquired from the deep water area of Pumoyum Co, southern Tibet. Twenty-five plant residue samples were selected, and organic carbon stable isotopes were obtained using the AMS 14 C chronological method. The 14 C age and carbon reservoir effect were calibrated with surface sedimentation rate measurements using 210 Pb dating. Results showed that the core sediment deposited over 19 cal ka BP. Based on a multi-proxy analysis of TOC and IC contents, grain size and pollen assemblage data, the palaeoclimatic evolution of Pumoyum Co was reconstructed since the last glacial. Pumoyum Co was a shallow lake prior to 16.2 cal ka BP; although the glacier around the lake began to melt due to increasing temperatures, climate was still cold and dry. In the interval of 16.2-11.8 cal ka BP, the sedimentary environment fluctuated drastically and frequently. Two cold-events occurred at 14.2 and 11.8 cal ka BP, and these may correspond to the Older Dryas and the Younger Dryas events, respectively. After 11.8 cal ka BP, Pumoyun Co developed into the deep lake as it is now. The lake water temperature was relatively lower at that time because of influx of cold water from glacial meltwater entering the lake. As a result, the multi-proxy indicators showed no sign of warm conditions. Comparisons between the sedimentary record of Pumoyum Co with that of other lakes of the same age in southern Tibet indicate a warmer climate following the last deglaciation influenced the southeastern Tibetan Plateau. These results imply that the southwest Asian monsoon gradually became stronger since the deglaciation during its expansion to the inner plateau. The glacial-supplied water of the lake responded sensitively to cold-events. The entire southern Tibet region was dominantly influenced climatically by the southwest Asian monsoon during the Holocene.LU XinMiao ZHU LiPing NISHIMURA Mitsugu MORITA Yoshimune WATANABE Takahiro NAKAMURA Toshio WANG Yong 2011Chinese Science Bulletin2011,56,27:10
9Immunological Effects of Silica and Asbestos显示文摘Silicosis patients(SILs) and patients who have been exposed to asbestos develop not only respiratory diseases but also certain immunological disorders. In particular,SIL sometimes complicates autoimmune diseases such as systemic scleroderma,rheumatoid arthritis(known as Caplan syndrome) ,and systemic lupus erythematoses. In addition,malignant complications such as lung cancer and malignant mesothelioma often occurr in patients exposed to asbestos,and may be involved in the reduction of tumor immunity. Although silica-induced disorders of autoimmunity have been explained as adjuvant-type effects of silica,more precise analyses are needed and should reflect the recent progress in immunomolecular findings. A brief summary of our investigations related to the immunological effects of silica/asbestos is presented. Recent advances in immunomolecular studies led to detailed analyses of the immunological effects of asbestos and silica. Both affect immuno-competent cells and these effects may be associated with the pathophysiological development of complications in silicosis and asbestos-exposed patients such as the occurrence of autoimmune disorders and malignant tumors,respectively. In addition,immunological analyses may lead to the development of new clinical tools for the modification of the pathophysiological aspects of diseases such as the regulation of autoimmunity or tumor immunity using cell-mediated therapies,various cytokines,and molecule-targeting therapies. In particular,as the incidence of asbestos-related malignancies is increasing and such malignancies have been a medical and social problem since the summer of 2005 in Japan,efforts should be focused on developing a cure for these diseases to eliminate nationwide anxiety.Takemi Otsuki Megumi Maeda Shuko Murakami Hiroaki Hayashi Yoshie Miura Masayasu Kusaka Takashi Nakano Kazuya Fukuoka Takumi Kishimoto Fuminori Hyodoh Ayako Ueki Yasumitsu Nishimura 2007Cellular & Molecular Immunology2007,4,4:9
10肿瘤的细胞免疫治疗显示文摘近年来,肿瘤的常规治疗方法均取得了很大改进,患者的长期存活率有所提高。手术、放射治疗和化学治疗能治愈部分肿瘤患者,但由于不能杀死全部肿瘤细胞,多数患者仍不能免于复发或转移的发生。作为现代肿瘤治疗的第4种模式,张毅 Michael Nishimura 2011郑州大学学报(医学版)2011,46,2:9
11在哪个与狭窄的乐队成像放大了内视镜检查法的胃的联系 mucosa 的淋巴的组织淋巴瘤的一个盒子在诊断是有用的显示文摘 Recently, we reported a case of gastric mucosaassociated lymphoid tissue (MALT) lymphoma presenting with unique vascular features. In the report, we defined the tree-like appearance (TLA) on the images of abnormal blood vessels which resembled branches from the trunk of a tree in the shiny mucosa, in which the glandular structure was lost. The 67-year-old female was diagnosed with gastric MALT lymphoma. The patient received eradication therapy for H. pylori. Conventional endoscopy revealed multiple ill-delineated brownish depressions in the stomach and cobblestonelike mucosa was observed at the greater curvature to the posterior wall of the upper gastric body 7 mo after successful eradication. Unsuccessful treatment of gastric MALT lymphoma was suspected on conventional endoscopy. Conventional endoscopic observations found focal depressions and cobblestone-like appearance, and these lesions were subsequently observed using magnified endoscopy combined with narrow band imaging to identify abnormal vessels presenting with a TLA within the lesions. Ten biopsies were taken from the area where abnormal vessels were present within these lesions. Ten biopsies were also taken from the lesions without abnormal vessels as a control. A total of 20 biopsy samples were evaluated to determine whether the diagnosis of MALT lymphoma could be obtained histologically from each sample. A positive diagnosis was obtained in 8/10 TLA (+) sites and in 2/10 TLA(-) sites. Target biopsies of the site with abnormal blood vessels can potentially improve diagnostic accuracy of gastric MALT lymphoma.Kouichi Nonaka Keiko Ishikawa Shin Arai Masamitsu Nakao Michio Shimizu Takaki Sakurai Koji Nagata Makoto Nishimura Osamu Togawa Yasutoshi Ochiai Yutaka Sasaki Hiroto Kita 2012World Journal of Gastrointestinal Endoscopy2012,4,4:8
12Endoscopic submucosal dissection for early esophageal neoplasms using the stag beetle knife显示文摘AIM To determine short-and long-term outcomes of endoscopic submucosal dissection(ESD) using the stag beetle(SB) knife, a scissor-shaped device.METHODS Seventy consecutive patients with 96 early esophageal neoplasms, who underwent ESD using a SB knife at Kure Medical Center and Chugoku Cancer Center, Japan, between April 2010 and August 2016, were retrospectively evaluated. Clinicopathological characteristics of lesions and procedural adverse events were assessed. Therapeutic success was evaluated on the basis of en bloc, histologically complete, and curative or non-curative resection rates. Overall and tumor-specific survival, local or distant recurrence, and 3-and 5-year cumulative overall metachronous cancer rates were also assessed.RESULTS Eligible patients had dysplasia/intraepithelial neoplasia(22%) or early cancers(squamous cell carcinoma, 78%). The median procedural time was 60 min and on average, the lesions measured 24 mm in diameter, yielding 33-mm tissue defects. The en bloc resection rate was 100%, with 95% and 81% of dissections deemed histologically complete and curative, respectively. All procedures were completed without accidental incisions/perforations or delayed bleeding. During follow-up(mean, 35 ± 23 mo), no local recurrences or metastases were observed. The 3-and 5-year survival rates were 83% and 70%, respectively, with corresponding rates of 85% and 75% for curative resections and 74% and 49% for noncurative resections. The 3-and 5-year cumulative rates of metachronous cancer in the patients with curative resections were 14% and 26%, respectively.CONCLUSION ESD procedures using the SB knife are feasible, safe, and effective for treating early esophageal neoplasms, yielding favorable short-and long-term outcomes.Toshio Kuwai Toshiki Yamaguchi Hiroki Imagawa Ryoichi Miura Yuki Sumida Takeshi Takasago Yuki Miyasako Tomoyuki Nishimura Sumio Iio Atsushi Yamaguchi Hirotaka Kouno Hiroshi Kohno Sauid Ishaq 2018World Journal of Gastroenterology2018,24,15:7

14Complete response to preoperative chemoradiotherapy in highly advanced gastric adenocarcinoma显示文摘This report presents a case of highly advanced gastric cancer that achieved a histologically complete response (CR) to preoperative chemoradiotherapy with S-1 plus low-dose Cisplatin. A 60-year-old male patient underwent FDG positron emission tomography (PET) during a routine health examination. The patient was found to have swollen paraaortic lymph nodes. Shortly thereafter, he was diagnosed with gastric carcinoma with a type 2 tumor in the antrum with paraaortic lymph node metastases based on FDG-PET, endoscopic examination and abdominal computed tomography. After the completion of chemoradiation therapy (CRT), the tumor and the paraaortic lymph node metastases disappeared. The patient underwent surgery 5 wk after the completion of CRT, including a subtotal gastrectomy with Rouxen-Y reconstruction, D3 lymph node dissection and a left adrenalectomy. No cancer cells were detected in the resected specimen either in the primary lesion or lymph nodes, thus confirming a pathologically CR to CRT (CR grade 3). The patient has been stable and well without any evidence of recurrence for 48 mo after surgery. Such a preoperative CRT regimen might therefore be very effective for treatment of some advanced gastric cancers.Hironori Shigeoka Haruhiko Imamoto Yasumasa Nishimura Taro Shimono Hiroshi Furukawa Hiroshi Imamura Takushi Yasuda Hitoshi Shiozaki 2010World Journal of Gastrointestinal Oncology2010,2,6:6
15有为决定早阶段的区分的胃的癌的扩展区域的 NBI 的在我的 DL 的实用性显示文摘 AIM: To investigate whether magnifying endoscopy with narrow band imaging (ME-NBI) is useful for evaluating the area of superficial, depressed- or flat-type differentiated adenocarcinoma of the stomach. METHODS: This procedure was performed in Saitama Medical University International Medical Center, Japanese Red Cross Kumamoto Hospital and Kitakyushu Municipal Medical Center. The subjects were 31 patients in whom biopsy findings, from superficial, depressed- or flat-type gastric lesion, suggested differentiated adenocarcinoma in the above 3 hospitals between January and December 2009. Biopsy was performed on the lesion and non-lesion sides of a boundary (imaginary boundary) visualized on ME-NBI. The results were pathologically investigated. We evaluated the accuracy of estimating a demarcation line (DL) on ME-NBI in comparison with biopsy findings as a gold standard. RESULTS: The DL that could be recognized at 2 points on the orifice and anal sides of each lesion during ME-NBI was consistent with the pathological findings in 22 patients with 0-Ⅱc lesions, 7 with 0-Ⅱb lesions, and 2 with 0-Ⅱb + Ⅱc lesions, showing an accuracy of 100%. CONCLUSION: The results suggest the usefulness of ME-NBI for evaluating the area of superficial, depressed- and flat-type differentiated adenocarcinoma of the stomach.Kouichi Nonaka Masaaki Namoto Hideki Kitada Michio Shimizu Yasutoshi Ochiai Osamu Togawa Masamitsu Nakao Makoto Nishimura Keiko Ishikawa Shin Arai Hiroto Kita 2012World Journal of Gastrointestinal Endoscopy2012,4,8:6

18高可靠性IGBT模块封装的设计显示文摘本文给出了当前的IGBT模块封装设计的原则,重点是封装结构和可靠性之间的关系,特别是温度循环性能。复杂的IGBT模块内部含有不同的材料。因为不同的热膨胀系数,层间介面处的物理损坏会伴随着一系列温度循环而不断累积。IGBT模块的寿命周期主要依赖于其材料的组合和结构设计上。作为一种尝试,本文针对未来IGBT在较高的运行温度下的可能性,谈到了当前的热优化设计和键合技术研究。Yoshitaka Nishimura Kazunaga Oonishi Fumihiko Momose Tomoaki Goto 袁海斌(译) 2010电力电子2010,,4:5
19Aggregation-induced emission and thermally activated delayed fluorescence of 2,6-diaminobenzophenones显示文摘Exploration of novel organic luminophores that exhibit thermally activated delayed fluorescence(TADF) in the aggregated state is very crucial for advance of delayed luminescence-based applications such as time-gated bio-sensing and temperature sensing.We report herein that synthesis, photophysical properties, molecular and crystal structures, and theoretical calculations of 2,6-bis(diarylamino)benzophenones. Absorption spectra in solution and calculations using density functional theory(DFT) method revealed that the optical excitation took place through intramolecular charge-transfer from one diarylamino moiety to an aroyl group. While the benzophenones did not luminesce in solution, the solids of the benzophenones emitted green light with moderate-to-good quantum yields. Thus, the benzophenones exhibit aggregation-induced emission. Based on the lifetime measurement, the green emission of the solids was found to include TADF. The emergence of the TADF is supported by the small energy gap between the excited singlet and triplet states, which was estimated by time-dependent DFT calculations. Thin films of poly(methyl methacrylate) doped by the benzophenones also showed green prompt and delayed fluorescence whose lifetimes were in the order of microseconds. Linear correlation between logarithm value of TADF lifetime and temperature was observed with the benzophenone in powder, suggesting that the benzophenones can serve as molecular thermometers workable under aqueous conditions.Masaki Shimizu Masaki Nakatani Kenta Nishimura 2018Science China Chemistry2018,61,8:5
20Decrease in Serum Amyloid a Protein Levels Following Three-month Stays in Negatively Charged Particle-dominant Indoor Air Conditions显示文摘Objective The changes in serum adipokines and cytokines related to oxidative stress were examined during 3 months ‘Off to On' and ‘On to Off' periods using negatively charged particle-dominant indoor air conditions(NCPDIAC).Methods Seven volunteers participated in the study,which included ‘OFF to 3 months ON' periods(ON trials) for a total of 16 times,and ‘ON to 3 months OFF'(OFF trials) periods for a total of 13 times.Results With the exception of one case,serum amyloid A(SAA) levels decreased significantly during the ON trials.Conclusion Considering that SAA is an acute phase reactive protein such as C reactive protein(CRP),this observed decrease might indicate the prevention of cardiovascular and atherosclerotic changes,since an increase in high-sensitive CRP is associated with the subsequent detection of these events.Suni Lee Shoko Yamamoto Yasumitsu Nishimura Hidenori Matsuzaki Kei Yoshitome Tamayo Hatayama Miho Ikeda YU Min Nagisa Sada Naoko Kumagai-Takei Takemi Otsuki 2018Biomedical and Environmental Sciences2018,31,5:5
