| 1 | Adiponectin deficiency enhances colorectal carcinogenesis and liver tumor formation induced by azoxymethane in mice显示文摘AIM:To investigate the causal relationship between hypoadiponectinemia and colorectal carcinogenesis in in vivo experimental model,and to determine the con-tribution of adiponectin defi ciency to colorectal cancer development and proliferation.METHODS:We examined the influence of adiponectin defi ciency on colorectal carcinogenesis induced by the administration of azoxymethane(AOM)(7.5 mg/kg,in-traperitoneal injection once a week for 8 wk),by using adiponectin-knockout(KO) mice.RESULTS:At 53 wk after the fi rst AOM treatment,KOmice developed larger and histologically more progres-sive colorectal tumors with greater frequency com-pared with wild-type(WT) mice,although the tumor incidence was not different between WT and KO mice.KO mice showed increased cell proliferation of colorec-tal tumor cells,which correlated with the expression levels of cyclooxygenase-2(COX-2) in the colorectal tumors.In addition,KO mice showed higher incidence and frequency of liver tumors after AOM treatment.Thirteen percent of WT mice developed liver tumors,and these WT mice had only a single tumor.In contrast,50% of KO mice developed liver tumors,and 58% of these KO mice had multiple tumors.CONCLUSION:Adiponectin deficiency enhances colorectal carcinogenesis and liver tumor formation induced by AOM in mice.This study strongly suggests that hypoadiponectinemia could be involved in the pathogenesis for colorectal cancer and liver tumor in human subjects. | Tamao Nishihara Miyako Baba Morihiro Matsuda Masahiro Inoue Yasuko Nishizawa Atsunori Fukuhara Hiroshi Araki Shinji Kihara Tohru Funahashi Shinji Tamura Norio Hayashi Hiroyasu Iishi Iichiro Shimomura | 2008 | World Journal of Gastroenterology2008，14，42： | 12 |
| 2 | High circulating tumor cell concentrations in a specific subtype of gastric cancer with diffuse bone metastasis at diagnosis显示文摘AIM: To clarify the biological feature contributing to gastric cancer with diffuse bone metastases at diagnosis.METHODS: The participants visited the Department of Clinical Oncology, Akita University Hospital, from January 2014 to August 2015. The selection criterion for gastric cancer with diffuse bone metastases at diagnosis includes over 29 hot spots of bone scintigraphy. Circulating tumor cell were collected from 20 m L of peripheral venous blood drawn using a Cell Search kit and a Cell Tracks Auto Prep system by SRL, a clinical laboratory. The endpoints of this study were correlations between circulating tumor cells(CTC) count and therapeutic outcomes. RESULTS: Among 39 patients with gastric cancer, 5 patients met the criterion. The incidence of this subtype was 12.8%. CTC counts ranged from 235 to 6440 cells/7.5 m L of peripheral blood(median of 1724). These values were much higher than common gastric cancers(2 cells). In chemo-sensitive cases, CTC counts decreased within 14 d(median) from 275, 235 and 1724 to 2, 7 and 66, respectively. On the other hand, CTC counts increased after treatment failure or insensitive case from 2, 7 and 6440 to 787, 513 and 7885, respectively. The correlation between CTC count and survival time showed a trend, but did not reach significance(Y = 234.6- 0.03 X, P = 0.085).CONCLUSION: High CTC count is a biological hallmark of this subtype, and can be used as a direct and definitive indicator of therapeutic outcome. | Kazuhiro Shimazu Koji Fukuda Taichi Yoshida Masahiro Inoue Hiroyuki Shibata | 2016 | World Journal of Gastroenterology2016，22，26： | 9 |
| 3 | Aspirin-induced small bowel injuries and the preventive effect of rebamipide显示文摘AIM:To evaluate the influence of taking low-dose aspirin for 4 wk on small intestinal complications and to examine the preventive effect of rebamipide.METHODS:This study was conducted as a single-center,randomized,double-blind,cross-over,placebo-controlled study.Eleven healthy male subjects were enrolled.Each subject underwent video capsule endos-copy after 1 and 4 wk of taking aspirin and omepra-zole,along with either rebamipide or placebo therapy.The primary endpoint was to evaluate small bowel damage in healthy subjects before and after taking low-dose aspirin for 4 wk.RESULTS:The number of subjects with mucosal breaks(defined as multiple erosions and/or ulcers)were 1 at 1 wk and 1 at 4 wk on the jejunum,and 6 at 1 wk(P = 0.0061)and 7 at 4 wk on the ileum(P =0.0019).Rebamipide significantly prevented mucosal breaks on the ileum compared with the placebo group(P = 0.0173 at 1 wk and P = 0.0266 at 4 wk).CONCLUSION:Longer-term,low-dose aspirin adminis-tration induced damage in the small bowel.Rebamipide prevented this damage,and may be a candidate drug for treating aspirin-induced small bowel complications. | Kazuhiro Mizukami Kazunari Murakami Takashi Abe Kunimitsu Inoue Masahiro Uchida Tadayoshi Okimoto Masaaki Kodama Toshio Fujioka | 2011 | World Journal of Gastroenterology2011，17，46： | 8 |

| 6 | A novel negative regulatory mechanism of Smurf2 in BMP/Smad signaling in bone显示文摘Transforming growth factor-β(TGF-β)and bone morphogenetic protein(BMP)play important roles in bone metabolism.Smad ubiquitination regulatory factors(Smurfs)regulate TGF-β/BMP signaling via ubiquitination,resulting in degradation of signaling molecules to prevent excessive activation of TGF-β/BMP signaling.Though Smurf2 has been shown to negatively regulate TGF-β/Smad signaling,its involvement in BMP/Smad signaling in bone metabolism has not been thoroughly investigated.In the present study,we sought to evaluate the role of Smurf2 in BMP/Smad signaling in bone metabolism.Absorbable collagen sponges containing 3μg of recombinant human BMP2(rhBMP2)were implanted in the dorsal muscle pouches of wild type(WT)and Smurf2−/−mice.The rhBMP2-induced ectopic bone in Smurf2−/−mice showed greater bone mass,higher mineral apposition and bone formation rates,and greater osteoblast numbers than the ectopic bone in WT mice.In WT mice,the ectopic bone consisted of a thin discontinuous outer cortical shell and scant inner trabecular bone.In contrast,in Smurf2−/−mice,the induced bone consisted of a thick,continuous outer cortical shell and abundant inner trabecular bone.Additionally,rhBMP2-stimulated bone marrow stromal cells(BMSCs)from Smurf2−/−mice showed increased osteogenic differentiation.Smurf2 induced the ubiquitination of Smad1/5.BMP/Smad signaling was enhanced in Smurf2−/−BMSCs stimulated with rhBMP2,and the inhibition of BMP/Smad signaling suppressed osteogenic differentiation of these BMSCs.These findings demonstrate that Smurf2 negatively regulates BMP/Smad signaling,thereby identifying a new regulatory mechanism in bone metabolism. | Junichi Kushioka Takashi Kaito Rintaro Okada Hiroyuki Ishiguro Zeynep Bal Joe Kodama Ryota Chijimatsu Melanie Pye Masahiro Narimatsu Jeffrey LWrana Yasumichi Inoue Hiroko Ninomiya Shin Yamamoto Takashi Saitou Hideki Yoshikawa Takeshi Imamura | 2020 | Bone Research2020，8，4： | 6 |
| 7 | Pluripotent stem cell-derived neural stem cells: From basic research to applications显示文摘Basic research on pluripotent stem cells is designed to enhance understanding of embryogenesis, whereas applied research is designed to develop novel therapies and prevent diseases. Attainment of these goals has been enhanced by the establishment of embryonic stem cell lines, the technological development of genomic reprogramming to generate induced-pluripotent stem cells, and improvements in in vitro techniques to manipulate stem cells. This review summarizes the techniques required to generate neural cells from pluripotent stem cells. In particular, this review describes current research applications of a simple neural differentiation method, the neural stem sphere method, which we developed. | Masahiro Otsu Takashi Nakayama Nobuo Inoue | 2014 | World Journal of Stem Cells2014，6，5： | 5 |

| 13 | Ureteral calculi secondary to a gradually migrated acupuncture needle显示文摘We herein presented a case of calculi secondary to a migrated acupuncture needle.A 74-year-old woman with a history of acupuncture therapy for lumbago was referred to our hospital for treatment of ureteral and renal pelvic calculi.Abdominal multi-detector computed tomography scans showed ipsilateral hydronephrosis and two calculi secondary to a migrated acupuncture needle.First,a percutaneous nephrolithotomy was performed to extract two calculi and fine needle fragments from the pelvis.Subsequently,residual needle fragments and calculi in the ureter were then removed by flexible transurethral lithotripsy using a holmium laser.In the present case,the formation of the calculi was caused by a migrated acupuncture needle.Calculi and needle fragments were removed safely endoscopically because the whole calculi and needle fragments were located in the ureteral lumen.ª2021 Editorial Office of Asian Journal of Urology.Production and hosting by Elsevier B.V.This is an open access article under the CC BY-NC-ND license(http://gffzzeb6f7f563f66445dhx9pw9cc6nvux6uxk.ffgz.tsg.suse.edu.cn/licenses/by-nc-nd/4.0/). | Masahiro Matsuki Atsushi Wanifuchi Ryuta Inoue Fumiyasu Takei Yasuharu Kunishima | 2021 | Asian Journal of Urology2021，8，1： | 2 |
| 14 | Metachronous penile metastasis from rectal cancer after total pelvic exenteration显示文摘Despite its abundant vascularization and extensive circulatory communication with neighboring organs, metastases to the penis are a rare event. A 57-yearold male, who had undergone total pelvic exenteration for rectal cancer sixteen months earlier, demonstrated an abnormal uptake within his penis by positron emission tomography/computed tomography. A single elastic nodule of the middle penis shaft was noted deep within Bucks fascia. No other obvious recurrent site was noted except the penile lesion. Total penectomy was performed as a curative resection based on a diagnosis of isolated penile metastasis from rectal cancer. A histopathological examination revealed an increase of well differentiated adenocarcinoma in the corpus spongiosum consistent with his primary rectal tumor. The immunohistochemistry of the tumor cells demonstrated positive staining for cytokeratin 20 and negative staining for cytokeratin 7, which strongly supported a diagnosis of penile metastasis from the rectum. The patient is alive more than two years without any recurrence. | Yuta Kimura Keiichi Nasu Hiroki Matsunaga Masahiro Warabi Satoru Inoue | 2012 | World Journal of Gastroenterology2012，18，38： | 2 |
| 15 | Induction of ischemic tolerance in rat liver via reduced nicotinamide adenine dinucleotide phosphate oxidase in Kupffer cells显示文摘AIM: To elucidate the mechanisms of hepatocyte preconditioning by H2O2 to better understand the pathophysiology of ischemic preconditioning. METHODS: The in vitro effect of H2O2 pretreatment was investigated in rat isolated hepatocytes subjected to anoxia/reoxygenation. Cell viability was assessed with propidium iodide fluorometry. In other experiments, rat livers were excised and subjected to warm ischemia/ reperfusion in an isolated perfused liver system to determine leakage of liver enzymes. Preconditioning was performed by H2O2 perfusion, or by stopping the perfusion for 10 min followed by 10 min of reperfusion. To inhibit Kupffer cell function or reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, gadolinium chloride was injected prior to liver excision, or diphenyleneiodonium, an inhibitor of NADPH oxidase, was added to the perfusate, respectively. Histological detection of oxygen radical formation in Kupffer cells was performed by perfusion with nitro blue tetrazolium. RESULTS: Anoxia/reoxygenation decreased hepatocyte viability compared to the controls. Pretreatment with H2O2 did not improve such hepatocyte injury. In liver perfusion experiments, however, H2O2 preconditioning reduced warm ischemia/reperfusion injury, which wasreversed by inhibition of Kupffer cell function or NADPH oxidase. Histological examination revealed that H2O2 preconditioning induced oxygen radical formation in Kupffer cells. NADPH oxidase inhibition also reversed hepatoprotection by ischemic preconditioning. CONCLUSION: H2O2 preconditioning protects hepato- cytes against warm ischemia/reperfusion injury via NADPH oxidase in Kupffer cells, and not directly. NADPH oxidase also mediates hepatoprotection by ischemic preconditioning. | Kazuaki Tejima Masahiro Arai Hitoshi Ikeda Tomoaki Tomiya Mikio Yanase Yukiko Inoue Takako Nishikawa Naoko Watanabe Natsuko Ohtomo Masao Omata Kenji Fujiwara | 2007 | World Journal of Gastroenterology2007，13，38： | 2 |

| 17 | A case of chronic pancreatitis in which endoscopic ultrasonography was effective in the diagnosis of a pseudoaneurysm显示文摘Endoscopic ultrasonography (EUS) was performed on a patient being treated for chronic pancreatitis because a submucosal tumor was observed in the stomach during gastrointestinal endoscopy. As internal pulsa- tile blood flow on Doppler was present, the diagnosis of an aneurysm was made. The pseudoaneurysm of the left gastric artery was embolized with histoacryl and lipiodol and the splenic artery was embolized with coils at the location of the pseudoaneurysm to prevent hemorrhage. Follow up EUS confirmed the cessation of blood flow from the pseudoaneurysm. Clinicians encountering a gastric submucosal tumor-like protrusion in a patient with chronic pancreatitis should use EUS to investigate the possibility of a pseudoaneurysm, which must be treated as quickly as possible once identified. | Kazuhiro Fukatsu Kazuki Ueda Hiroki Maeda Yasunobu Yamashita Masahiro Itonaga Yoshiyuki Mori Kosaku Moribata Naoki Shingaki Hisanobu Deguchi Shotaro Enomoto Izumi Inoue Takao Maekita Mikitaka Iguchi Hideyuki Tamai Jun Kato Masao Ichinose | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，7： | 2 |
