| 1 | 期待很久的2004年9月28日M6.0级帕克菲尔德地震的震磁效应显示文摘1976年以来,在加利福尼亚帕克菲尔德地区沿圣安德烈斯断层上长约60km的闭锁—蠕动过渡带,布设了由7个采样同步的质子磁力仪构成的差动连接的台阵,对该地区的局部磁场进行了准确的测量。2004年9月28日的M6.0级帕克菲尔德地震的震中恰好位于这个台阵之内,此次地震在其中的5个台站的观测中产生了0.2nT~0.5nT的同震磁场变化。但是从地震发生前1个月、前1周及前数天的地磁观测数据中,都检测不到明显高于背景噪声水平的震前磁场变化(由于没有可检测出的形变、地震活动或孔隙压力变化数据,理论上也应观测不到震前磁场变化)。在地震破裂末端附近的一个台站也记录了0.01Hz~20Hz频带内的电场和磁场数据,借助于沿断层的北西延长线上距该台站约115km的另一个台站的观测数据,对来自电离层和磁层的同模式噪声进行了校正。校正后的数据中既没有发现1989年ML7.1级洛马普列塔地震前可能存在ULF频带(0.01Hz~20Hz)的异常磁噪声,也没有发现相同震级的希腊地震震前产生的电场变化。基于应变、位移和地震数据反演得到的地震一致滑动和可变滑动压磁模型,能够计算出与磁力仪台阵观测到的结果相符的磁场扰动。1993年以来,该区域内长期存在着与荷载增加一致的较高磁场变化,与之相伴的是由一个两色EDM台网和另一个较小的钻孔应变仪台网观测到的剪应变率的长期增长及表现在1992、1993和1994年各发生了一次M4.5~5.0级地震的地震活动性的增强。集成了所有这些数据建立的模型揭示了该区域在深度剖面上有增大的滑动,这也许对2004年9月28日M6.0级帕克菲尔德地震的最后发生起到了重要的作用。本次地震以及其他发生于圣安德烈斯断层系内其他地方的M5~7.3级地震的震前电场和磁场前兆的缺乏,表明了仅利用现有的这些电磁数据来对破坏性地震做出有意义的预测看来并不可能。 | M.

| 2 | Gastroduodenal ulcer bleeding in elderly patients on low dose aspirin therapy显示文摘AIM To determine the clinical characteristics of elderly patients of hemorrhagic gastroduodenal ulcer on low-dose aspirin(LDA)therapy.METHODS A total of 1105 patients with hemorrhagic gastroduodenal ulcer treated in our hospital between January 2000 and March 2016 were grouped by age and drugs used,and these groups were compared in several factors.These groups were compared in terms of length of hospital stay,presence/absence of hemoglobin(Hb)decrease,presence/absence of blood transfusion,Forrest Ⅰ,percentage of Helicobacter pylori infection,presence/absence of underlying disease,and percentage of severe cases.RESULTS The percentage of blood transfusion(62.6%vs 47.7%,P<0.001),Hb decrease(53.8% vs 40.8%,P<0.001),and the length of hospital stay(23.5 d vs 16.7 d,P<0.001)were significantly greater in those on drug therapy.The percentage of blood transfusion(65.3%vs 47.8%,P<0.001),Hb decrease(54.2%vs 42.1%,P<0.001),and length of hospital stay(23.3 d vs 17.5 d,P<0.001)were significantly greater in the elderly.In comparison with the LDA monotherapy group,the percentage of severe cases was significantly higher in the LDA combination therapy group when elderly patients were concerned(16.1%vs34.0%,P=0.030).Meanwhile,among those on LDA monotherapy,there was no significant difference between elderly and non-elderly(16.1%vs 16.0%,P=0.985).CONCLUSION A combination of LDA with antithrombotic drugs or nonsteroidal anti-inflammatory drugs(NSAIDs)contributes to aggravation.And advanced age is not an aggravating factor when LDA monotherapy is used. | Koh Fukushi Keiichi Tominaga Kazunori Nagashima Akira Kanamori Naoya Izawa Mimari Kanazawa Takako Sasai Hideyuki Hiraishi | 2018 | World Journal of Gastroenterology2018，24，34： | 3 |
| 3 | Clinical importance of colonoscopy in patients with gastric neoplasm undergoing endoscopic submucosal dissection显示文摘AIM To evaluate the usefulness of total colonoscopy(TCS) for patients undergoing gastric endoscopic submucosal dissection(ESD) and to assess risk factors for colorectal neoplasms.METHODS Of the 263 patients who underwent ESD at our department between May 2010 and December 2013, 172 patients undergoing TCS during a one-year period before and after ESD were targeted. After excluding patients with a history of surgery or endoscopic therapy for colorectal neoplasms, 158 patients were analyzed. Of the 868 asymptomatic patients who underwent TCS during the same period because of positive fecal immunochemical test(FIT) results, 158 patients with no history of either surgery or endoscopic therapy for colorectal neoplasms who were matched for age and sex served as the control group for comparison.RESULTS TCS revealed adenoma less than 10 mm in 53 patients(33.6%), advanced adenoma in 17(10.8%), early colorectal cancer in 5(3.2%), and advanced colorectalcancer in 4(2.5%). When the presence or absence of adenoma less than 10 mm, advanced adenoma, and colorectal cancer and the number of adenomas were compared between patients undergoing ESD and FITpositive patients, there were no statistically significant differences in any of the parameters assessed. The patients undergoing ESD appeared to have the same risk of colorectal neoplasms as the FIT-positive patients. Colorectal neoplasms were clearly more common in men than in women(P = 0.031). Advanced adenoma and cancer were significantly more frequent in patients with at least two of the following conditions: hypertension, dyslipidemia, and diabetes mellitus(P = 0.019).CONCLUSION In patients undergoing gastric ESD, TCS appears to be important for detecting synchronous double neoplasms. Advanced adenoma and cancer were more common in patients with at least two of the following conditions: hypertension, dyslipidemia, and diabetes mellitus. Caution is therefore especially warranted in patients with these risk factors. | Chieko Tsuchida Naoto Yoshitake Hitoshi Kino Yoshihito Kaneko Masakazu Nakano Kohei Tsuchida Keiichi Tominaga Takako Sasai Hironori Masuyama Hidetsugu Yamagishi Yasuo Imai Hideyuki Hiraishi | 2017 | World Journal of Gastroenterology2017，23，23： | 3 |

| 5 | Sporadic gastric carcinoid tumor successfully treated by two-stage laparoscopic surgery:A case report显示文摘We report a case of sporadic gastric carcinoid tumor successfully treated by two-stage laparoscopic surgery.A 38-year old asymptomatic woman was referred to our hospital for evaluation of a submucosal tumor of the stomach.Endoscopic examination showed a solitary submucosal tumor without ulceration or central depression on the posterior wall of the antrum and biopsy specimens were not sufficient to determine the diagnosis.Endoscopic ultrasound revealed a tumor nearly 2 cm in diameter arising from the muscle layer and a computed tomography scan showed the tumor enhanced in the arterial phase.Laparoscopic wedge resection was performed for definitive diagnosis.Pathologically,the tumor was shown to be gastric carcinoid infiltrating the muscle layer which indicated the probability of lymph node metastasis.Serum gastrin levels were normal.As a radical treatment,laparoscopy-assisted distal gastrectomy with regional lymphadenectomy was performed 3 wk after the initial surgery.Finally,pathological examination revealed no lymph node metastasis. | Takahiro Kinoshita Takashi Oshiro Tasuku Urita Yutaka Yoshida Mitsuru Ooshiro Shinichi Okazumi Ryoji Katoh Daisuke Sasai Nobuyuki Hiruta | 2010 | World Journal of Gastrointestinal Surgery2010，2，11： | 2 |

| 20 | 钢液中氧化铝夹杂物的形核生长及去除动力学显示文摘在钢液Al脱氧实验的基础上,从动力学的角度,分析了Al脱氧机理。本研究的Al脱氧动力学考虑了界面性质的影响。Al脱氧机理包括,Al加入之后,Al_(2)O_(3)的形核和生长,以及脱氧平衡后,Al_(2)O_(3)夹杂的团聚和去除。Al_(2)O_(3)的形核数量密度为(0.72-1.62)×10^(14) m^(-3),随着过饱和程度的增加以及Al_(2)O_(3)核心与钢液界面张力的减小,形核数量密度增大。这些趋势可以用均相形核理论来解释。我们估算出,Al_(2)O_(3)形核的平均界面张力为1.43 N·m^(-1),频率因子为4.27X10^(35) m^(-3)·s^(-1),形核时间为0.01 s,平均形核速率为1.96x10^(16)m^(-3)·s^(-1)。加入Al后,在2.2-3.7 s内,通过钢液中过饱和[O]的扩散,Al_(2)O_(3)核心迅速生长为直径为2.0-2.6μm的Al_(2)O_(3)夹杂物。在随后的脱氧平衡中,随着钢液中[O]浓度的增加,Al_(2)O_(3)夹杂物的生长速率增加,其生长机理可以用Ostwald成熟理论来解释。同时,Al_(2)O_(3)团簇夹杂物随着凝聚力的增大而增大,夹杂物的凝聚既包括单夹杂物的合并,也包括上浮过程中的簇状夹杂物的合并。 | Katsuhiro SASAI 顾尚军(译) 高长益(译) 叶雅妮(译) 谢祥(译) 吴学林(译) 张东升(译) 陈倩(译) | 2022 | 水钢科技2022，，2： | 1 |
