| 1 | Nonalcoholic fatty liver disease and hepatic cirrhosis: comparison with viral hepatitis-associated steatosis显示文摘Nonalcoholic fatty liver disease(NAFLD) including nonalcoholic steatohepatitis(NASH) is globally increasing and has become a world-wide health problem. Chronic infection with hepatitis B virus or hepatitis C virus(HCV) is associated with hepatic steatosis. Viral hepatitis-associated hepatic steatosis is often caused by metabolic syndrome including obesity,type 2 diabetes mellitus and/or dyslipidemia. It has been reported that HCV genotype 3 exerts direct metabolic effects that lead to hepatic steatosis. In this review,the differences between NAFLD/NASH and viral hepatitis-associated steatosis are discussed. | Yuki Haga Tatsuo Kanda Reina Sasaki Masato Nakamura Shingo Nakamoto Osamu Yokosuka | 2015 | World Journal of Gastroenterology2015，21，46： | 20 |
| 2 | Enhancement patterns of pancreatic adenocarcinoma on conventional dynamic multi-detector row CT:Correlation with angiogenesis and fibrosis显示文摘AIM:To evaluate retrospectively the correlation between enhancement patterns on dynamic computed tomography (CT) and angiogenesis and fibrosis in pancreatic adenocarcinoma.METHODS: Twenty-three patients with pancreatic adenocarcinoma underwent dynamic CT and tumor resection. In addition to the absolute and relative enhanced value that was calculated by subtracting the attenuation value on pre-contrast from those on contrast-enhanced CT in each phase, we defined one parameter, 'tumor-aorta enhancement ratio', which was calculated by dividing enhancement of pancreatic cancer by enhancement of abdominal aorta in each phase. These enhancement patterns were correlated with the level of vascular endothelial growth factor (VEGF), microvessel density (MVD), and extent of fibrosis.RESULTS: The absolute enhanced value in the arterial phase correlated with the level of VEGF and MVD (P=0.047, P=0.001). The relative enhanced value in arterial phase and tumor-aorta enhancement ratio (arterial) correlated with MVD (P=0.003, P=0.022). Tumor-aorta enhancement ratio (arterial) correlated negatively with the extent of fibrosis (P=0.004). The tumors with greater MVD and higher expression of VEGF tended to show high enhancement in the arterial dominant phase. On the other hand, the tumors with a larger amount of fibrosis showed a negative correlation with the grade of enhancement during the arterial phase.CONCLUSION: Enhancement patterns on dynamic CT correlated with angiogenesis and may be modified by the extent of fibrosis. | Yuki Hattori Toshifumi Gabata Osamu Matsui Kentaro Mochizuki Hirohisa Kitagawa Masato Kayahara Tetsuo Ohta Yasuni Nakanuma | 2009 | World Journal of Gastroenterology2009，15，25： | 15 |
| 3 | Sofosbuvir treatment and hepatitis C virus infection显示文摘Hepatitis C virus(HCV) infection is a serious problem worldwide.The use of interferon-based therapy has made HCV eradication challenging.The recent appearance of direct-acting antiviral agents(DAAs) has changed HCV therapy.Combining the use of DAAs with peginterferon and ribavirin has improved treatment efficacy.Furthermore,the combination of different orally administered DAAs has enabled interferon-free therapy with much higher efficacy and safety.In particular,sofosbuvir,a nucleotide-based NS5 B inhibitor,prevents HCV RNA synthesis by acting as a 'chain terminator'.Treatment with sofosbuvir has attained an extremely high rate of sustained virologic response.The current review summarizes the efficacy and safety of sofosbuvir therapy. | Masato Nakamura Tatsuo Kanda Yuki Haga Reina Sasaki Shuang Wu Shingo Nakamoto Shin Yasui Makoto Arai Fumio Imazeki Osamu Yokosuka | 2016 | World Journal of Hepatology2016，8，3： | 4 |

| 5 | Protocol for laparoscopic cholecystectomy: Is it rocket science?显示文摘Laparoscopic cholecystectomy(LC) does not require advanced techniques, and its performance has therefore rapidly spread worldwide. However, the rate of biliary injuries has not decreased. The concept of the critical view of safety(CVS) was first documented two decades ago. Unexpected injuries are principally due to misidentification of human factors. The surgeon's assumption is a major cause of misidentification, and a high level of experience alone is not sufficient for successful LC. We herein describe tips and pitfalls of LC in detail and discuss various technical considerations.Finally, based on a review of important papers and our own experience, we summarize the following mandatory protocol for safe LC:(1) consideration that a high level of experience alone is not enough;(2) recognition of the plateau involving the common hepatic duct and hepatic hilum;(3) blunt dissection until CVS exposure;(4) Calot's triangle clearance in the overhead view;(5) Calot's triangle clearance in the view from underneath;(6) dissection of the posterior right side of Calot's triangle;(7) removal of the gallbladder body; and(8) positive CVS exposure. We believe that adherence to this protocol will ensure successful and beneficial LC worldwide, even in patients with inflammatory changes and rare anatomies. | Tomohide Hori Fumitaka Oike Hiroaki Furuyama Takafumi Machimoto Yoshio Kadokawa Toshiyuki Hata Shigeru Kato Daiki Yasukawa Yuki Aisu Maho Sasaki Yusuke Kimura Yuichiro Takamatsu Masato Naito Masaya Nakauchi Takahiro Tanaka Daigo Gunji Kiyokuni Nakamura Kiyoko Sato Masahiro Mizuno Taku Iida Shintaro Yagi Shinji Uemoto Tsunehiro Yoshimura | 2016 | World Journal of Gastroenterology2016，22，47： | 3 |

| 14 | Color representation method using RGB color binary-weighted computer-generated holograms显示文摘We propose a method for color electroholography using a simple red–green–blue(RGB) gradation representation method without controlling the respective brightness of the reference RGB-colored lights. The proposed method uses RGB multiple bit planes comprising RGB binary-weighted computer-generated holograms with various light transmittances. The object points of a given three-dimensional(3D) object are assigned to RGB multiple bit planes according to their RGB gradation levels. The RGB multiple bit planes are sequentially displayed in a time-division-multiplexed manner. Consequently, the proposed method yields a color gradation representation of a reconstructed 3D object. | Masato Fujiwara Naoki Takada Hiromitsu Araki Shohei Ikawa Yuki Maeda Hiroaki Niwase Minoru Oikawa Takashi Kakue Tomoyoshi Shimobaba Tomoyoshi Ito | 2018 | Chinese Optics Letters2018，16，8： | 1 |
