1Gastric adenocarcinoma of the fundic gland(chief cell-predominant type): A review of endoscopic and clinicopathological features显示文摘Gastric adenocarcinoma of the fundic gland(chief cellpredominant type, GA-FG-CCP) is a rare variant of welldifferentiated adenocarcinoma, and has been proposed to be a novel disease entity. GA-FG-CCP originates from the gastric mucosa of the fundic gland region without chronic gastritis or intestinal metaplasia. The majority of GA-FG-CCPs exhibit either a submucosal tumor-like superficial elevated shape or a flat shape on macroscopic examination. Narrow-band imaging with endoscopic magnification may reveal a regular or an irregular microvascular pattern, depending on the degree of tumor exposure to the mucosal surface. Pathological analysis of GA-FG-CCPs is characterized by a high frequency of submucosal invasion, rare occurrences of lymphatic and venous invasion, and low-grade malignancy. Detection of diffuse positivity for pepsinogen-I by immunohistochemistry is specific for GA-FG-CCP. Careful endoscopic examination and detailed pathological evaluation are essential for early and accurate diagnosis of GA-FG-CCP. Nearly all GA-FG-CCPs are treated by endoscopic resection due to their small tumor size and low risk of recurrence or metastasis.Masaki Miyazawa Mitsuru Matsuda Masaaki Yano Yasumasa Hara Fumitaka Arihara Yosuke Horita Koichiro Matsuda Akito Sakai Yatsugi Noda 2016World Journal of Gastroenterology2016,22,48:26
2Gastric adenocarcinoma of fundic gland type: Five cases treated with endoscopic resection显示文摘Recently,a new disease entity termed gastric adenocarcinoma of fundic gland type(GA-FG) was proposed.We treated five cases of GA-FG with endoscopic submucosal dissection.All tumors were small and located in the upper third of the stomach.Four tumors were macroscopically identified as 0-IIa and one was identified as 0-Ⅱb.Narrow-band imaging with magnifying endoscopy showed an irregular microvascular pattern in 2 cases and a regular microvascular pattern in the remainder.All tumors arose from the deep layer of the lamina propria mucosae and showed submucosal invasion.Lymphatic invasion was seen only in one case,while no venous invasion was recognized.All tumors were positive for pepsinogen-Ⅰ and MUC6 by immunohistochemistry.None showed p53 overexpression,and the labeling index of Ki-67 was low in all cases.All cases have been free from recurrence or metastasis.Herein,we discussed the clinicopathological features of GA-FG in comparison with past reports.Masaki Miyazawa Mitsuru Matsuda Masaaki Yano Yasumasa Hara Fumitaka Arihara Yosuke Horita Koichiro Matsuda Akito Sakai Yatsugi Noda 2015World Journal of Gastroenterology2015,21,26:16
3Bacteremia in hemodialysis patients显示文摘Infection is a common complication and is the second leading cause of death in hemodialysis patients. The risk of bacteremia in hemodialysis patients is 26-fold higher than in the general population, and 1/2-3/4 of the causative organisms of bacteremia in hemodialysis patients are Gram-positive bacteria. The ratio of resistant bacteria in hemodialysis patients compared to the general population is unclear. Several reports have indicated that hemodialysis patients have a higher risk of methicillin-resistant Staphylococcus aureus infection. The most common site of infection causing bacteremia is internal prostheses; the use of a hemodialysis catheter is the most important risk factor for bacteremia. Although antibiotic lock of hemodialysis catheters and topical antibiotic ointment can reduce catheter-related blood stream infection(CRBSI), their use should be limited to necessary cases because of the emergence of resistant organisms. Systemic antibiotic administration and catheter removal is recommended for treating CRBSI, although a study indicated the advantages of antibiotic lock and guidewire exchange of catheters over systemic antibiotic therapy. An infection control bundle recommended by the Center for Disease Control and Prevention succeeded in reducing bacteremia in hemodialysis patients with either a catheter or arteriovenous fistula. Appropriate infection control can reduce bacteremia in hemodialysis patients.Masashi Suzuki Nobuhiko Satoh Motonobu Nakamura Shoko Horita George Seki Kyoji Moriya 2016World Journal of Nephrology2016,5,6:14
4Reactive lymphoid hyperplasia of the liver:A case report and review of literature显示文摘有反应淋巴的增生(RLH ) 的一个 53 岁的女病人的一个盒子,肝的临床上指明的同样假的淋巴瘤在这篇文章被描述。病人为顺便说一下在另一所医院发现的肝的肿瘤的进一步的评估进入我们的医院。各种各样的诊断方法,包括的 ultrasonography (美国) ,计算机化的断层摄影术(CT ) ,磁性的回声成像(MRI ) 和肝的血管造影术与与肝细胞癌(HCC ) 一致的突出的调查结果在肝显示了三小损害。外科的切除术被执行,三损害是作为肝的 RLH 诊断的用显微镜。损害与滤泡和 hyalinized 包括了淋巴样细胞的巨大的渗入内部小囊的空格。Immunohistochemical 检查表明渗透的淋巴细胞没有突出的原子非典型和 polyclonality。肝的 RLH 是一个很稀罕的条件,仅仅 12 个案例在英语文学被报导了。报导案例的多数是中年的女人并且关于他们的一半有象自体免疫的甲状腺炎那样的一些免疫逻辑畸形, Sjogren 的症候群,主要免疫不全,主要胆汁性肝硬变。因为他们临床上经常作为 HCC 被误诊,外科是为这些病人的治疗的选择。尽管他们的病理类似于恶性淋巴瘤,临床的功课是完全良性的。作者建议肝的 RLH 能被它的临床的特征从 HCC 区别。Takuro Machida Toshiyuki Takahashi Tomoo Itoh Michiaki Hirayama Takayuki Morita Shoichi Horita 2007World Journal of Gastroenterology2007,13,40:13
5A pedunculated polyp-shaped small-bowel lymphangioma causing gastrointestinal bleeding and treated by double-balloon enteroscopy显示文摘We report a rare case of a small-bowel lymphangioma causing massive gastrointestinal (GI) bleeding that we successfully diagnosed and treated using double-balloon enteroscopy (DBE). An 81-year-old woman suffering from repeated GI bleeding of unknown origin underwent a capsule endoscopy at a previous hospital. She was suspected of having bleeding from the jejunum, and was referred to our department for diagnosis and treatment. An oral DBE revealed a 20 mm × 10 mm, regularly surfaced, white to yellowish, elongated, pedunculated jejunal polyp with small erosions at 10 cm distal to the ligament of Treiz. Since no other source of bleeding was identified by endoscopy in the deep jejunum, anendoscopic polypectomy (EP) was performed for this lesion. A subsequent histopathological examination of the resected polyp showed clusters of lymphatic vessels with marked cystic dilatation in the submucosa and the deep layer of the lamina propria mucosae. These characteristics are consistent with the typical features of small-bowel lymphangioma with erosions. Although clip-ping hemostasis was performed during EP, re-bleeding occurred. Finally, a complete hemostasis was achieved by performing an additional argon plasma coagulation.Akihiko Kida Koichiro Matsuda Satoshi Hirai Akiyoshi Shimatani Yousuke Horita Katsushi Hiramatsu Mitsuru Matsuda Hidero Ogino Shin Ishizawa Yatsugi Noda 2012World Journal of Gastroenterology2012,18,34:5
6Effect of equal-channel angular pressing on pitting corrosion resistance of anodized aluminum-copper alloy显示文摘The effect of equal-channel angular pressing(ECAP) on the pitting corrosion resistance of anodized Al-Cu alloy was investigated by electrochemical techniques in a solution containing 0.2 mol/L AlCl3 and also by surface analysis.Anodizing was conducted for 20 min at 200 and 400 A/m2 in a solution containing 1.53 mol/L H2SO4 and 0.018 5 mol/L Al2(SO4)3·16H2O at 20 ℃.Anodized Al-Cu alloy was immediately dipped in boiling water for 20 min to seal the micro pores present in anodic oxide films.The time required before initiating pitting corrosion of anodized Al-Cu alloy is longer with ECAP than without,indicating that ECAP process improves the pitting corrosion resistance of anodized Al-Cu alloy.Second phase precipitates such as Si,Al-Cu-Mg and Al-Cu-Si-Fe-Mn intermetallic compounds are present in Al-Cu alloy and the size of these precipitates is greatly decreased by application of ECAP.Al-Cu-Mg intermetallic compounds are dissolved during anodization,whereas the precipitates composed of Si and Al-Cu-Si-Fe-Mn remain in anodic oxide films due to their more noble corrosion potential than Al.FE-SEM and EPMA observation reveal that the pitting corrosion of anodized Al-Cu alloy occurs preferentially around Al-Cu-Si-Fe-Mn intermetallic compounds,since the anodic oxide films are absent at the boundary between the normal oxide films and these impurity precipitates.The improvement of pitting corrosion resistance of anodized Al-Cu alloy processed by ECAP appears to be attributed to a decrease in the size of precipitates,which act as origins of pitting corrosion.In-Joon SON Hiroaki NAKANO Satoshi OUE Shigeo KOBAYASHI Hisaaki FUKUSHIMA Zenji HORITA 2009中国有色金属学会会刊:英文版2009,19,4:5
