| 1 | Long-term outcomes and prognostic factors of patients with obstructive colorectal cancer: A multicenter retrospective cohort study显示文摘AIM: To investigate the long-term oncologic outcomes and prognostic factors in patients with obstructive colorectal cancer(CRC) at multiple Japanese institutions.METHODS: We identified 362 patients diagnosed with obstructive colorectal cancer from January 1, 2002 to December 31, 2012 in Yokohama Clinical Oncology Group's department of gastroenterological surgery. Among them, 234 patients with stage Ⅱ/Ⅲ disease who had undergone surgical resection of their primary lesions were analyzed, retrospectively. We report the long-term outcomes, the risk factors for recurrence, and the prognostic factors.RESULTS: The five-year disease free survival and cancer-specific survival were 50.6% and 80.3%, respectively. A multivariate analysis showed the ASAPS(HR = 2.23, P = 0.026), serum Albumin ≤ 4.0 g/d L(HR = 2.96, P = 0.007), T4 tumor(HR = 2.73, P = 0.002) and R1 resection(HR = 6.56, P = 0.02) to be independent risk factors for recurrence. Furthermore, poorly differentiated cancers(HR = 6.28, P = 0.009), a T4 tumor(HR = 3.46, P = 0.011) and R1 resection(HR = 6.16, P = 0.006) were independent prognostic factors in patients with obstructive CRC.CONCLUSION: The outcomes of patients with obstructive CRC was poor. T4 tumor and R1 resection were found to be independent prognostic factors for both recurrence and survival in patients with obstructive CRC. | Ishibe Atsushi Ota Mitsuyoshi Yamaguchi Kazuya Kaida Syuhei Kamiya Noriyuki Momiyama Masashi Watanabe Akira Sekizawa Kentaro Kamimukai Nobuyuki Sugimasa Natsuko Watanabe Jun Ichikawa Yasushi Kunisaki Chikara Endo Itaru | 2016 | World Journal of Gastroenterology2016，22，22： | 9 |

| 15 | Event-Oriented Dynamic Security Service for Demand Response in Smart Grid Employing Mobile Networks显示文摘Equipped with millions of sensors and smart meters in smart gird,a reliable and resilient wireless communication technology is badly needed.Mobile networks are among the major energy communication networks which contribute to global energy consumption increase rapidly.As one of core technologies of smart grid employing mobile networks,Demand Response(DR) helps improving efficiency,reliability and security for electric power grid infrastructure.Security of DR events is one of the most important issues in DR.However,the security requirements of different DR events are dynamic for variousactual demands.To address this,an event-oriented dynamic security service mechanism is proposed for DR.Three kinds of security services including security access service,security communication service and security analysis service for DR event are composited dynamically by the fine-grained sub services.An experiment prototype of the network of State Grid Corporation of China(SGCC) is established.Experiment and evaluations shows the feasibility and effectiveness of the proposed scheme in smart grid employing mobile network. | GUO Longhua DONG Mianxiong Kaoru Ota WU Jun LI Jianhua | 2015 | China Communications2015，12，12： | 0 |
| 16 | Current state of practice for colonic diverticular bleeding in 37 hospitals in Japan: A multicenter questionnaire study显示文摘AIM To clarify the current state of practice for colonic diverticular bleeding(CDB) in Japan.METHODS We conducted multicenter questionnaire surveys of the practice for CDB including clinical settings(8 questions),diagnoses(8 questions),treatments(7 questions),and outcomes(4 questions) in 37 hospitals across Japan.The answers were compared between hospitals with high and low number of inpatient beds to investigate which factor influenced the answers.RESULTS Endoscopists at all 37 hospitals answered the questions,and the mean number of endoscopists at these hospitals was 12.7.Of all the hospitals,computed tomography was performed before colonoscopy in 67% of the hospitals.The rate of bowel preparation was 46.0%.Early colonoscopy was performed within 24 h in 43.2% of the hospitals.Of the hospitals,83.8% performed clipping as first-line endoscopic therapy.More than half of the hospitals experienced less than 20% rebleeding events after endoscopic hemostasis.No significant difference was observed in the annual number of patients hospitalized for CDB between high-(≥700 beds) and low-volume hospitals.More emergency visits(P=0.012) and endoscopists(P=0.015),and less frequent participation of nursing staff in early colonoscopy(P=0.045) were observed in the high-volume hospitals.CONCLUSION Some practices unique to Japan were found,such as performing computed tomography before colonoscopy,no bowel preparation,and clipping as first-line therapy.Although,the number of staff differed,the practices for CDB were common irrespective of hospital size. | Ryota Niikura Naoyoshi Nagata Hisashi Doyama Ryosuke Ota Naoki Ishii Katsuhiro Mabe Tsutomu Nishida Takuto Hikichi Kazuki Sumiyama Jun Nishikawa Toshio Uraoka Shu Kiyotoki Mitsuhiro Fujishiro Kazuhiko Koike | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，20： | 0 |
