| 1 | Efficient hemostatic method for endoscopic submucosal dissection of colorectal tumors显示文摘AIM:To evaluate a new hemostatic method using hemostatic forceps to prevent perforation and perioperative hemorrhage during colonic endoscopic submucosal dissection(ESD).METHODS:We studied 250 cases,in which ESD for colorectal tumors was performed at the Kyoto Prefectural University of Medicine or Nara City Hospital between 2005 and 2010.We developed a new hemostatic method using hemostatic forceps in December 2008 for the efficient treatment of submucosal thick vessels.ESD was performed on 126 cases after adoption of the new method(the adopted group)and the new method was performed on 102 of these cases.ESD was performed on 124 cases before the adoption of the new method (the unadopted group).The details of the new method are as follows:firstly,a vessel was coagulated using the hemostatic forceps in the soft coagulation mode according to the standard procedure,and the coagulated vessel was removed using the forceps in the'endocut' mode without perioperative hemorrhage.Secondly,the partial surrounding submucosa was dissected using the forceps in the endocut mode.In the current study,we evaluated the efficacy of this method.RESULTS:Coagulated vessels were successfully removed using the hemostatic forceps in all 102 cases without severe perioperative hemorrhage.Moderate perioperative hemorrhage occurred in five cases(4.9%);however,it was stopped by immediately reuse of the hemostatic forceps.The partial surrounding submucosa was dissected using the forceps in all 102 cases.In the adopted group,the median operation time was 105 min.The proportion of endoscopic en bloc resection was 92.8%(P<0.01)compared to 80.6%in the unadopted group.The postoperative hemorrhage and perforation rates were 2.3%and 2.3%.The rate of perforation was significantly lower than that in the unadopted group (9.6%,P<0.01).We evaluated the ease of use of this method by allowing our three trainees to performed ESD on 46 cases,which were accomplished without any severe hemorrhage.CONCLUSION:The new method effectively treated submucosal thick vessels and shows promise for the prevention of perforation and perioperative hemorrhage in colonic ESD. | Naohisa Yoshida Yuji Naito Munehiro Kugai Ken Inoue Naoki Wakabayashi Nobuaki Yagi Akio Yanagisawa Toshikazu Yoshikawa | 2010 | World Journal of Gastroenterology2010，16，33： | 4 |

| 3 | First successful perinatal management of pregnancy after ABO-incompatible liver transplantation显示文摘Many papers have reported on pregnancy and delivery after liver transplantation, but there have been no reports on pregnancy after ABO-incompatible liver transplantation. This paper reports the first successful pregnancy and delivery of a newborn after ABOincompatible liver transplantation for fulminant hepatic failure. The patient was a 39-year-old female. She had an ABO-incompatible liver transplantation, donated from her husband, due to subacute fulminant hepatitis of unknown etiology. She was taking tacrolimus, methylprednisolone, and mizoribine orally for the maintenance of immunosuppression at the time of discharge. She was discharged uneventfully on postoperative day 38 without any rejection episodes. At 1 year and 6 mo after transplantation, she indicated a wish to become pregnant. Therefore, treatment with mycophenolate mofetil was interrupted at that time. After two miscarriages, she finally became pregnant and delivered transvaginally 3 years after the transplantation. All of the pregnancies were conceived naturally. The newborn was female with a birth weight of 3146 g; the Apgar scores were 9 and 10. Delivery was performed smoothly, and the newborn exhibited no malformations. The mother and the newborn were discharged uneventfully. We suggest that pregnancy is possible for recipients after ABO-incompatible liver transplantation. | Hisanobu Higashi Hideaki Obara Kei Miyakoshi Masahiro Shinoda Minoru Kitago Naoki Shimojima Yuta Abe Taizo Hibi Hiroshi Yagi Kentaro Matsubara Yohei Yamada Osamu Itano Ken Hoshino Tatsuo Kuroda Yuko Kitagawa | 2017 | World Journal of Gastroenterology2017，23，3： | 1 |

| 7 | Barium hexaferrite/muscovite heteroepitaxy with mechanically robust perpendicular magnetic anisotropy显示文摘Recent advances in the design and development of magnetic storage devices have led to an enormous interest in materials with perpendicular magnetic anisotropy(PMA)property.The past decade has witnessed a huge growth in the development of flexible devices such as displays,circuit boards,batteries,memories,etc.since they have gradually made an impact on people’s lives.Thus,the integration of PMA materials with flexible substrates can benefit the development of flexible magnetic devices.In this study,we developed a heteroepitaxy of BaFe_(12)O_(19)(BaM)/muscovite which displays both mechanical flexibility and PMA property.The particular PMA property was characterized by vibrating sample magnetometer,magnetic force microscopy,and x-ray absorption spectroscopy.To quantify the PMA property of the system,the intrinsic magnetic anisotropy energy density of~2.83 Merg cm−3 was obtained.Furthermore,the heterostructure exhibits robust PMA property against severe mechanical bending.The findings of this study on the BaM/muscovite heteroepitaxy have several important implications for research in next-generation flexible magnetic recording devices and actuators. | Wei-En Ke Pao-Wen Shao Chang-Yang Kuo Haili Song Rong Huang Naoki Yagi Tsuyoshi Kimura Yugandhar Bitla Chun-Fu Chang Ying-Hao Chu | 2021 | npj Flexible Electronics2021，5，1： | 0 |
| 8 | Helicobacter cinaedi bacteremia with cellulitis after ABO-incompatible living-donor liver transplantation: Case report显示文摘Helicobacter cinaedi(H. cinaedi), a Gram-negative spiral-shaped bacterium, is an enterohepatic nonHelicobacter pylori Helicobacter species. We report the first case of H. cinaedi bacteremia with cellulitis after liver transplantation. A 48-year-old male, who had been a dog breeder for 15 years, underwent ABO-incompatible living-donor liver transplantation for hepatitis C virus-induced decompensated cirrhosis using an anti-hepatitis B core antibody-positive graft. The patient was preoperatively administered rituximab and underwent plasma exchange twice to overcome blood type incompatibility. After discharge, he had been doing well with immunosuppression therapy comprising cyclosporine, mycophenolate mofetil, and steroid according to the ABO-incompatible protocol of our institution. However, 7 mo after transplantation, he was admitted to our hospital with a diagnosis of recurrent cellulitis on the left lower extremity, and H. cinaedi was detected by both blood culture and polymerase chain reaction analysis. Antibiotics improved his symptoms, and he was discharged at day 30 after admission. Clinicians should be more aware of H. cinaedi in immunocompromised patients, such as ABO-incompatible transplant recipients. | Kohei Mishima Hideaki Obara Kayoko Sugita Masahiro Shinoda Minoru Kitago Yuta Abe Taizo Hibi Hiroshi Yagi Kentaro Matsubara Takehiko Mori Yaoko Takano Hiroshi Fujiwara Osamu Itano Naoki Hasegawa Satoshi Iwata Yuko Kitagawa | 2015 | World Journal of Gastroenterology2015，21，25： | 0 |
