| 1 | Removal of diminutive colorectal polyps: A prospective randomized clinical trial between cold snare polypectomy and hot forceps biopsy显示文摘AIM To compare the efficacy and safety of cold snare polypectomy(CSP) and hot forceps biopsy(HFB) for diminutive colorectal polyps.METHODS This prospective, randomized single-center clinical trial included consecutive patients ≥ 20 years of age with diminutive colorectal polyps 3-5 mm from December 2014 to October 2015. The primary outcome measures were en-bloc resection(endoscopic evaluation) and complete resection rates(pathological evaluation). The secondary outcome measures were the immediate bleeding or immediate perforation rate after polypectomy, delayed bleeding or delayed perforation rate after polypectomy, use of clipping for bleeding or perforation, and polyp retrieval rate. Prophylactic clipping after polyp removal wasn't routinely performed.RESULTS Two hundred eight patients were randomized into the CSP(102), HFB(106) and 283 polyps were evaluated(CSP: 148, HFB: 135). The en-bloc resection rate was significantly higher with CSP than with HFB [99.3%(147/148) vs 80.0%(108/135), P < 0.0001]. The complete resection rate was significantly higher with CSP than with HFB [80.4%(119/148) vs 47.4%(64/135), P < 0.0001]. The immediate bleeding rate was similar between the groups [8.6%(13/148) vs 8.1%(11/135), P = 1.000], and endoscopic hemostasis with hemoclips was successful in all cases. No cases of perforation or delayed bleeding occurred. The rate of severe tissue injury to the pathological specimen was higher HFB than CSP [52.6%(71/135) vs 1.3%(2/148), P < 0.0001]. Polyp retrieval failure was encountered CSP(7), HFB(2).CONCLUSION CSP is more effective than HFB for resecting diminutive polyps. Further long-term follow-up study is required. | Yoriaki Komeda Hiroshi Kashida Toshiharu Sakurai George Tribonias Kazuki Okamoto Masashi Kono Mitsunari Yamada Teppei Adachi Hiromasa Mine Tomoyuki Nagai Yutaka Asakuma Satoru Hagiwara Shigenaga Matsui Tomohiro Watanabe Masayuki Kitano Takaaki Chikugo Yasutaka Chiba Masatoshi Kudo | 2017 | World Journal of Gastroenterology2017，23，2： | 20 |

| 3 | Light-absorbing Particles in Snow and Ice: Measurement and Modeling of Climatic and Hydrological impact显示文摘Light absorbing particles(LAP, e.g., black carbon, brown carbon, and dust) influence water and energy budgets of the atmosphere and snowpack in multiple ways. In addition to their effects associated with atmospheric heating by absorption of solar radiation and interactions with clouds, LAP in snow on land and ice can reduce the surface reflectance(a.k.a., surface darkening), which is likely to accelerate the snow aging process and further reduces snow albedo and increases the speed of snowpack melt. LAP in snow and ice(LAPSI) has been identified as one of major forcings affecting climate change, e.g.in the fourth and fifth assessment reports of IPCC. However, the uncertainty level in quantifying this effect remains very high. In this review paper, we document various technical methods of measuring LAPSI and review the progress made in measuring the LAPSI in Arctic, Tibetan Plateau and other mid-latitude regions. We also report the progress in modeling the mass concentrations, albedo reduction, radiative forcing, and climatic and hydrological impact of LAPSI at global and regional scales. Finally we identify some research needs for reducing the uncertainties in the impact of LAPSI on global and regional climate and the hydrological cycle. | Yun QIAN Teppei J.YASUNARI Sarah J.DOHERTY Mark G.FLANNER William K.M.LAU MING Jing Hailong WANG Mo WANG Stephen G.WARREN Rudong ZHANG | 2015 | Advances in Atmospheric Sciences2015，32，1： | 16 |

| 5 | Silver Nanowire Electrodes: Conductivity Improvement Without Post-treatment and Application in Capacitive Pressure Sensors显示文摘Transparent electrode based on silver nanowires(Ag NWs) emerges as an outstanding alternative of indium tin oxide film especially for flexible electronics. However, the conductivity of Ag NWs transparent electrode is still dramatically limited by the contact resistance between nanowires at high transmittance. Polyvinylpyrrolidone(PVP) layer adsorbed on the nanowire surface acts as an electrically insulating barrier at wire–wire junctions, and some devastating post-treatment methods are proposed to reduce or eliminate PVP layer, which usually limit the application of the substrates susceptible to heat or pressure and burden the fabrication with high-cost, time-consuming, or inefficient processes. In this work, a simple and rapid pre-treatment washing method was proposed to reduce the thickness of PVP layer from 13.19 to0.96 nm and improve the contact between wires. Ag NW electrodes with sheet resistances of 15.6 and 204 X sq-1have been achieved at transmittances of 90 and 97.5 %, respectively. This method avoided any post-treatments and popularized the application of high-performance Ag NW transparent electrode on more substrates. The improved Ag NWs were successfully employed in a capacitive pressure sensor with high transparency, sensitivity, and reproducibility. | Jun Wang Jinting Jiu Teppei Araki Masaya Nogi Tohru Sugahara Shijo Nagao Hirotaka Koga Peng He Katsuaki Suganuma | 2015 | Nano-Micro Letters2015，7，1： | 9 |

| 7 | Diabetes mellitus and metformin in hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the leading cause of cancer-related death worldwide. Diabetes mellitus, a risk factor for cancer, is also globally endemic. The clinical link between these two diseases has been the subject of investigation for a century, and diabetes mellitus has been established as a risk factor for HCC. Accordingly, metformin, a first-line oral anti-diabetic, was first proposed as a candidate anti-cancer agent in 2005 in a cohort study in Scotland. Several subsequent large cohort studies and randomized controlled trials have not demonstrated significant efficacy for metformin in suppressing HCC incidence and mortality in diabetic patients; however, two recent randomized controlled trials have reported positive data for the tumor-preventive potential of metformin in non-diabetic subjects. The search for biological links between cancer and diabetes has revealed intracellular pathways that are shared by cancer and diabetes. The signal transduction mechanisms by which metformin suppresses carcinogenesis in cell lines or xenograft tissues and improves chemoresistance in cancer stem cells have also been elucidated. This review addresses the clinical and biological links between HCC and diabetes mellitus and the anti-cancer activity of metformin in clinical studies and basic experiments. | Koji Fujita Hisakazu Iwama Hisaaki Miyoshi Joji Tani Kyoko Oura Tomoko Tadokoro Teppei Sakamoto Takako Nomura Asahiro Morishita Hirohito Yoneyama Tsutomu Masaki | 2016 | World Journal of Gastroenterology2016，22，27： | 7 |
| 8 | Duplication cyst of the small intestine found by double-balloon endoscopy:A case report显示文摘A 35-year-old man was admitted due to bloody stool and anemia. The bleeding source could not be detected by esophagogastroduodenoscopy or colonoscopy. Double balloon endoscopy (DBE) revealed a diverticulum-like hole in which coagula stuck in the ileum at 1 meter on the oral side from the ileocecal valve. The adjacent mucosa just to the oral side of the hole was elevated like a submucosal tumor. The lesion was considered the source of bleeding and removed surgically. It was determined to be a cyst with an ileal structure on the mesenteric aspect accompanying gastric mucosa. The diagnosis was a duplication cyst of the ileum,which is a rare entity that can cause gastrointestinal bleeding. In the present case,DBE was used to fi nd the hemorrhagic duplication cyst in the ileum. | Haruei Ogino Toshiaki Ochiai Norimoto Nakamura Daisuke Yoshimura Teppei Kabemura Tetsuya Kusumoto Hiroshi Matsuura Akihiko Nakashima Kuniomi Honda Kazuhiko Nakamura | 2008 | World Journal of Gastroenterology2008，14，24： | 5 |
| 9 | Endoscopic submucosal dissection in early gastric cancer in elderly patients and comorbid conditions显示文摘The prognosis of early gastric cancer(EGC) is good if there is no concomitant lymph node metastasis. Therefore, the early detection of EGC is important to improve the prognosis of patients with gastric cancer. In Japan, 40% to 50% of all gastric cancers are EGC, and endoscopic submucosal dissection(ESD) is widely accepted as a local treatment for these lesions, particularly for large lesions that at one time were an indication for gastrectomy because of the difficulty of en-bloc resection. Consequently, this procedure can preserve the entire stomach and the patient's postoperative quality of life. ESD has become a general technique with improved procedures and devices, and has become the preferred treatment for EGC rather than gastrectomy. Therefore, ESD may demonstrate many advantages in patients who have several comorbidities, particularly elderly population, patients taking antithrombotic agents, or patients with chronic kidney disease, or liver cirrhosis. However, it is not yet clear whether patients with both EGC and comorbidities are feasible candidates for ESD and whether they would consequently be able to achieve a survival benefit after ESD. In this review, we discuss the clinical problems of ESD in patients with EGC and those comorbid conditions. | Tsutomu Nishida Motohiko Kato Toshiyuki Yoshio Tomofumi Akasaka Teppei Yoshioka Tomoki Michida Masashi Yamamoto Shiro Hayashi Yoshito Hayashi Masahiko Tsujii Tetsuo Takehara | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，5： | 4 |

| 12 | Acute pancreatitis secondary to intramural duodenal hematoma:Case report and literature review显示文摘Nontraumatic intramural duodenal hematoma(IDH) is rare disease and it is generally related to coagulation abnormalities.Reports of nontraumatic IDH associated with pancreatic disease are relatively rare,and various conditions including acute or chronic pancreatitis are thought to be associated with nontraumatic IDH.However,the association between IDH and acute pancreatitis remains unknown.We report the case of a 45-year-old man who presented with vomiting and right hypochondrial pain.He had no medical history,but was a heavy drinker.The diagnosis of IDH was established by computed tomography,ultrasonography and endoscopy,and it was complicated by acute pancreatitis.The lesions resolved with conservative management.We discuss this case in the context of previously reported cases of IDH concomitant with acute pancreatitis.In our patient,acute pancreatitis occurred concurrently with hematoma,probably due to obstruction of the duodenal papilla,or compression of the pancreas caused by the hematoma.The present analysis of the published cases of IDH with acute pancreatitis provides some information on the pathogenesis of IDH and its relationship with acute pancreatitis. | Kazue Shiozawa Manabu Watanabe Yoshinori Igarashi Yasushi Matsukiyo Teppei Matsui Yasukiyo Sumino | 2010 | World Journal of Radiology2010，2，7： | 3 |

| 14 | Intragastric surgery using laparoscopy and oral endoscopy for gastric submucosal tumors显示文摘We review the techniques and outcomes of the intragastric resection for gastric submucosal tumors(GSTs) using laparoscope and oral endoscope. In the literature, the mean operation time, intraoperative blood loss, pathological size of the tumor and postoperative hospital stay were 134 min, minimal, 31 mm and 6.4 d, respectively. There were no particular perioperative complications during the follow-up period(mean: 121.3 mo). Intragastric surgery using laparoscopy and oral endoscopy can be considerably beneficial for patients with GSTs locating in the upper third of the stomach between 2-5 cm in diameter and < 8 cm2 in crosssectional area and located in the upper third of the stomach. | Nobumi Tagaya Teppei Tatsuoka Yawara Kubota Masayuki Takegami Nana Sugamata Kazuyuki Saito Takashi Okuyama Yoshitake Sugamata Masatoshi Oya | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，1： | 2 |
