| 1 | Transferring pose and augmenting background for deep humanimage parsing and its applications显示文摘Parsing of human images is a fundamental task for determining semantic parts such as the face,arms, and legs, as well as a hat or a dress. Recent deep-learning-based methods have achieved significant improvements, but collecting training datasets with pixel-wise annotations is labor-intensive. In this paper,we propose two solutions to cope with limited datasets.Firstly, to handle various poses, we incorporate a pose estimation network into an end-to-end humanimage parsing network, in order to transfer common features across the domains. The pose estimation network can be trained using rich datasets and can feed valuable features to the human-image parsing network. Secondly, to handle complicated backgrounds,we increase the variation in image backgrounds automatically by replacing the original backgrounds of human images with others obtained from large-scale scenery image datasets. Individually, each solution is versatile and beneficial to human-image parsing, while their combination yields further improvement. We demonstrate the effectiveness of our approach through comparisons and various applications such as garment recoloring, garment texture transfer, and visualization for fashion analysis. | Takazumi Kikuchi Yuki Endo Yoshihiro Kanamori Taisuke Hashimoto Jun Mitani | 2018 | Computational Visual Media2018，4，1： | 4 |
| 2 | Alpha-fetoprotein before and after pegylated interferon therapy for predicting hepatocellular carcinoma development显示文摘AIM: To investigate factors that accurately predict hepatocellular carcinoma(HCC) development after antiviral therapy in chronic hepatitis C(CHC) patients. METHODS: CHC patients who received pegylated interferon and ribavirin were enrolled in this cohort study that investigated the ability of alpha-fetoprotein(AFP) to predict HCC development after interferon(IFN) therapy. RESULTS: Of 1255 patients enrolled, 665 developed sustained virological response(SVR) during mean follow-up period of 5.4 years. HCC was occurred in 89 patients, and 20 SVR patients were included. Proportional hazard models showed that HCC occurred in SVR patients showing AFP ≥ 5 ng/m L before therapy and in non-SVR patients showing AFP ≥ 5 ng/m L before and 1 year after therapy besides older age, and low platelet counts. SVR patients showing AFP ≥ 5 ng/m L before therapy and no decrease in AFP to < 5 ng/m L 1 year after therapy had significantly higher HCC incidence than non-SVR patients showing AFP ≥ 5 ng/m L before therapy and decreased AFP(P = 0.043). AFP ≥ 5 ng/m L before therapy was significantly associated with low platelet counts and high values of alanine aminotransferase(ALT) in stepwise logistic regression analysis. After age, gender, platelet count, and ALT was matched by propensity score, significantly lower HCC incidence was shown in SVR patients showing AFP < 5 ng/m L before therapy than in those showing AFP ≥ 5 ng/m L.CONCLUSION: The criteria of AFP < 5 ng/m L before and 1 year after IFN therapy is a benefical predictor for HCC development in CHC patients. | Yasuto Takeuchi Fusao Ikeda Toshiya Osawa Yasuyuki Araki Kouichi Takaguchi Youichi Morimoto Noriaki Hashimoto Kousaku Sakaguchi Tatsuro Sakata Masaharu Ando Yasuhiro Makino Shuji Matsumura Hiroki Takayama Hiroyuki Seki Shintarou Nanba Yuki Moritou Tetsuya Yasunaka Hideki Ohnishi Akinobu Takaki Kazuhiro Nouso Yoshiaki Iwasaki Kazuhide Yamamoto | 2015 | World Journal of Hepatology2015，7，19： | 3 |
| 3 | Screening for hilar biliary invasion in ampullary cancer patients显示文摘BACKGROUND The treatment for ampullary cancer is pancreatoduodenectomy or local ampullectomy.However,effective methods for the preoperative investigation of hilar biliary invasion in ampullary cancer patients have not yet been identified.AIM To determine the necessity of and an appropriate method for investigating hilar biliary invasion of ampullary cancer.METHODS Among 43 ampullary cancer patients,34 underwent endoscopic treatment(n=9)or surgery(n=25).The use of imaging findings(thickening and enhancement of the bile duct wall on contrast-enhanced computed tomography,irregularity on endoscopic retrograde cholangiography,thickening of the entire bile duct wall on intraductal ultrasonography(IDUS),and partial thickening of the bile duct wall on IDUS)and biliary biopsy results for diagnosing hilar biliary invasion of ampullary cancer was compared.RESULTS Hilar invasion was not observed in every patient.Among the patients who did not undergo biliary stent insertion,the combination of partial thickening of the bile duct wall on IDUS and biliary biopsy results showed the highest accuracy(100%)for diagnosing hilar biliary invasion.However,each imaging method and biliary biopsy yielded some false-positive results.CONCLUSION Although some false-positive results were obtained with each method,the combination of partial thickening of the bile duct wall on IDUS and biliary biopsy results was useful for diagnosing hilar biliary invasion of ampullary cancer.However,hilar invasion of ampullary cancer is rare;therefore,the investigation of hilar biliary invasion of ampullary cancer might be unnecessary. | Tadayuki Takagi Mitsuru Sugimoto Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Jun Nakamura Mika Takasumi Minami Hashimoto Tsunetaka Kato Ryoichiro Kobashi Takumi Yanagita Yuko Hashimoto Shigeru Marubashi Takuto Hikichi Hiromasa Ohira | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，9： | 2 |

| 10 | Risk factors for de novo hepatitis B during solid cancer treatment显示文摘BACKGROUND Reactivation of hepatitis B virus(HBV)during anticancer treatment is a critical issue.When treating patients with solid tumors,it is unclear whether specific cancer types or treatments affect HBV reactivation in hepatitis B surface antigen(HBsAg)-negative and hepatitis B core antibody(HBcAb)-positive patients,socalled de novo hepatitis B patients.The risk of de novo hepatitis B may vary based on different background factors.AIM To determine the frequency and risk factors for de novo hepatitis B during solid tumor treatment.METHODS This retrospective cohort study comprised 1040 patients without HBsAgs and with HBcAbs and/or hepatitis B surface antibodies(HBsAbs).The patients were treated for solid cancer from 2008 to 2018 at the National Kyushu Cancer Center and underwent HBV DNA measurements.Patient characteristics and disease and treatment information were investigated.HBV DNA measurements were performed using TaqMan polymerase chain reaction(PCR).To identify the risk factors associated with HBV DNA expression,the age,sex,original disease,pathology,treatment method,presence or absence of hepatitis C virus(HCV),and HBsAb and/or HBcAb titers of all subjects were investigated.In patients with HBV DNA,the time of appearance,presence of HBsAgs and HBsAbs at the time of appearance,and course of the subsequent fluctuations in virus levels were also investigated.RESULTS Among the 1040 patients,938 were HBcAb positive,and 102 were HBcAb negative and HBsAb positive.HBV DNA expression was observed before the onset of treatment in nine patients(0.9%)and after treatment in 35 patients(3.7%),all of whom were HBcAb positive.The HBV reactivation group showed significantly higher median HBcAb values[9.00(8.12-9.89)vs 7.22(7.02-7.43),P=0.0001]and significantly lower HBsAb values(14 vs 46,P=0.0342)than the group without reactivation.Notably,the reactivated group showed a significantly higher proportion of cancers in organs related to digestion and absorption(79.0%vs 58.7%,P=0.0051).A high HBcAb titer and cancers in organs involved in digestion and absorption were identified as independent factors for HBV reactivation(multivariate analysis,P=0.0002 and P=0.0095).The group without HBsAbs tended to have a shorter time to reactivation(day 43 vs day 193),and the frequency of reactivation within 6 mo was significantly higher in this group(P=0.0459)than in the other group.CONCLUSION A high HBcAb titer and cancers in organs involved in digestion and absorption are independent factors that contribute to HBV reactivation during solid tumor treatment. | Rie Sugimoto Masayuki Furukawa Takeshi Senju Yoshihusa Aratake Yuki Tanaka Hiroki Inada Tatsuya Noguchi Lingaku Lee Masami Miki Yuji Maruyama Risa Hashimoto Terumasa Hisano Mototsugu Shimokawa | 2020 | World Journal of Clinical Cases2020，8，24： | 1 |

| 14 | Which scope is appropriate for endoscopic retrograde cholangiopancreatography after Billroth II reconstruction:An esophagogastroduodenoscope or a colonoscope?显示文摘BACKGROUND Recently,with the advent of more advanced devices and endoscopic techniques,endoscopic retrograde cholangiopancreatography(ERCP)in Billroth II(B-II)patients has been increasingly performed.However,the procedures are difficult,and the techniques and strategies have not been defined.AIM To reveal the appropriate scope for ERCP in B-II patients.METHODS Sixty ERCP procedures were performed on B-II patients between June 2005 and May 2018 at Fukushima Medical University Hospital,and in 44 cases,this was the first ERCP procedure performed by esophagogastroduodenoscopy(EGDS)or colonoscopy(CS)after B-II gastrectomy.These cases were divided into two groups:17 cases of ERCP performed by EGDS(EGDS group)and 27 cases of ERCP performed by CS(CS group).The patient characteristics and ERCP procedures were compared between the EGDS and CS groups.RESULTS The procedural time was significantly shorter in the EGDS group than in the CS group[median(range):60(20-100)vs 90(40-128)min,P value<0.01].CS was an independent factor of a longer ERCP procedural time according to the univariate and multivariate analyses(odds ratio:3.97,95%CI:1.05-15.0,P value=0.04).CONCLUSION Compared to CS,EGDS shortened the procedural time of ERCP in B-II patients. | Mitsuru Sugimoto Tadayuki Takagi Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Ko Watanabe Jun Nakamura Hitomi Kikuchi Mika Takasumi Minami Hashimoto Tsunetaka Kato TakutoHikichi Hiromasa Ohira | 2020 | World Journal of Gastrointestinal Endoscopy2020，12，8： | 1 |

| 19 | Can the wet suction technique change the efficacy of endoscopic ultrasound-guided fine-needle aspiration for diagnosing autoimmune pancreatitis type 1? A prospective single-arm study显示文摘BACKGROUND Other than surgery,endoscopic ultrasound-guided fine-needle aspiration(EUSFNA)is the only procedure for histologically diagnosing autoimmune pancreatitis(AIP).However,adequate specimens are difficult to obtain.Recently,more adequate specimens were reported to be obtained with EUS-FNA with a wet suction technique(WEST)than with conventional EUS-FNA.AIM To histologically diagnose AIP by EUS-FNA with a WEST.METHODS Eleven patients with possible type 1 AIP between February 2016 and August 2018 underwent EUS-FNA with a WEST(WEST group),with four punctures by 19 or 22 G needles.As a historical control,23 type 1 AIP patients who underwent no fewer than four punctures with 19 or 22 G needles were enrolled(DRY group).Patient characteristics and histological findings were compared between the two groups.RESULTS Three histopathological factors according to the International Consensus Diagnostic Criteria were significantly greater in the WEST group than the DRY group[lymphoplasmacytic infiltrate without granulocytic infiltration:9(81.8%)vs 6(26.1%),P=0.003,storiform fibrosis:5(45.5%)vs 1(4.3%),P=0.008,abundant(>10 cells/HPF)IgG4-positive cells:7(63.6%)vs 5(21.7%),P=0.026].Level 1 or level 2 histopathological findings were observed more often in the WEST group than in the DRY group[8(72.7%)vs 3(13.0%),P=0.001].CONCLUSION EUS-FNA with a WEST was more successful than standard EUS-FNA in histologically diagnosing AIP. | Mitsuru Sugimoto Tadayuki Takagi Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Ko Watanabe Jun Nakamura Hitomi Kikuchi Mika Takasumi Minami Hashimoto Tsunetaka Kato Takuto Hikichi Kenji Notohara Hiromasa Ohira | 2020 | World Journal of Clinical Cases2020，8，1： | 1 |
