| 1 | Clinical benefit of radiation therapy and metallic stenting for unresectable hilar cholangiocarcinoma显示文摘AIM:To determine the efficacy of external beam radiotherapy(EBRT),with or without intraluminal brachytherapy(ILBT),in patients with non-resected locally advanced hilar cholangiocarcinoma.METHODS:We analyzed 64 patients with locally advanced hilar cholangiocarcinoma,including 25 who underwent resection(17 curative and 8 non-curative),28 treated with radiotherapy,and 11 who received best supportive care(BSC).The radiotherapy group received EBRT(50 Gy,30 fractions),with 11 receiving an additional 24 Gy(4 fractions) ILBT by iridium-192 with remote after loading.ILBT was performed using percutaneous transhepatic biliary drainage(PTBD) route.Uncovered metallic stents(UMS) were inserted into nonresected patients with obstructive jaundice,with the exception of four patients who received percutaneous transhepatic biliary drainage only.UMS were placed endoscopically or percutaneously,depending on the initial drainage procedure.The primary endpoints were patient death or stent occlusion.Survival time of patients in the radiotherapy group was compared with that of patients in the resection and BSC groups.Stent patency was compared in the radiotherapy and BSC groups.RESULTS:No statistically significant differences in patient characteristics were found among the resection,radiotherapy,and BSC groups.Three patients in the radiotherapy group and one in the BSC group did not receive UMS insertion but received PTBD alone;cholangitis occurred after endoscopic stenting,and patients were treated with PTBD.A total of 16 patients were administered additional systemic chemotherapy(5-fluorouracil-based regimen in 9,S-1 in 6,and gemcitabine in 1).Overall survival varied significantly among groups,with median survival times of 48.7 mo in the surgery group,22.1 mo in the radiotherapy group,and 5.7 mo in the BSC group.Patients who underwent curative resection survived significantly longer than those who were not candidates for surgery(P = 0.0076).Cumulative survival in the radiotherapy group was significantly longer than in the BSC group(P = 0.0031),but did not differ significantly from those in the non-resection group.Furthermore,the median survival time of patients in the radiotherapy group who were considered for possible resection(excluding the seven patients who were not candidates for surgery due to comorbid disease or age) was 25.9 mo.Stent patency was evaluated only in the 24 patients who received a metallic stent.Stent patency was significantly longer in the radiotherapy than in the BSC group(P = 0.0165).Biliary drainage was not eliminated in any patient.To determine the efficacy of ILBT,we compared survival time and stent patency in the EBRT alone and EBRT plus ILBT groups.However,we found no significant difference in survival time between groups or for stent patencies.Hemorrhagic gastroduodenal ulcers were observed in 5 patients(17.9%),three in the EBRT plus ILBT group and two in the EBRT alone group.Ulcers occurred 5 mo,7 mo,8 mo,16 mo,and 29 mo following radiotherapy.All patients required hospitalization,but blood transfusions were unnecessary.All 5 patients recovered following the administration of anti-ulcer medication.CONCLUSION:Radiotherapy improved patient prognosis and the patency of uncovered metallic stents in patients with locally advanced hilar cholangiocarcinoma,but ILBT provided no additional benefits. | Hiroyuki Isayama Takeshi Tsujino Yousuke Nakai Takashi Sasaki Keiichi Nakagawa Hideomi Yamashita Taku Aoki Kazuhiko Koike | 2012 | World Journal of Gastroenterology2012，18，19： | 24 |
| 2 | Long-term prognostic impact of circulating tumour cells in gastric cancer patients显示文摘AIM To analyse the long-term prognostic impact of circulating tumour cells(CTCs) in gastric cancer patients who underwent surgery. METHODS A 7.5-m L peripheral vein blood sample was obtained from each patient with treatment-negative gastric adenocarcinoma before surgery. OBP-401, a telomerasespecific, replication-selective, oncolytic adenoviral agent carrying the green fluorescent protein gene, was used to label CTCs. Correlations between the number of CTCs and clinical end points were evaluated. RESULTS The median follow-up period of the surviving patients with gastric cancer was 60 mo. The CTC number tended to increase concomitantly with disease progression. The overall survival of patients with more than five CTCs in 7.5-m L of peripheral blood was lower than that of patients with five or less CTCs, although the difference was not significant(P = 0.183). A significant difference in relapse-free survival was found between patients with more than five and those with five or less CTCs(P = 0.034).CONCLUSION A lower number of CTCs was correlated with higher relapse-free survival rates in patients. Detection of CTCs using OBP-401 may be useful for predicting prognosis in gastric cancer. | Hiroaki Ito Jun Sato Yukio Tsujino Noriko Yamaguchi Satoshi Kimura Keigo Gohda Katsuhiro Murakami Manabu Onimaru Tohru Ohmori Fumihiro Ishikawa Haruhiro Inoue | 2016 | World Journal of Gastroenterology2016，22，46： | 8 |

| 4 | Clinical analysis of high serum IgE in autoimmune pancreatitis显示文摘AIM: To clarify the clinical significance of high serum IgE in autoimmune pancreatitis (AIP). METHODS: Forty-two AIP patients, whose IgE was measured before steroid treatment, were analyzed. To evaluate the relationship between IgE levels and the disease activity of AIP, we examined (1) Frequency of high IgE (> 170 IU/mL) and concomitant allergic dis-eases requiring treatment; (2) Correlations between IgG, IgG4, and IgE; (3) Relationship between the presence of extrapancreatic lesions and IgE; (4) Re-lationship between clinical relapse and IgE in patients treated with steroids, and (5) Transition of IgE before and after steroid treatment. RESULTS: IgE was elevated in 36/42 (86%) patients.Concomitant allergic disease was observed in seven patients (allergic rhinitis in three, bronchial asthma in three, and urticaria in one). There were no signifi-cant correlations between IgG, IgG4, and IgE (r = -0.168 for IgG, and r = -0.188 for IgG4). There was no significant difference in IgE in the patients with and without extrapancreatic lesions (526 ± 531 IU/mL vs 819 ± 768 IU/mL, P = 0.163), with and without clini-cal relapse (457 ± 346 IU/mL vs 784 ± 786 IU/mL, P = 0.374). There was no significant difference in IgE between before and after steroid treatment (723 ± 744 IU/mL vs 673 ± 660 IU/mL, P = 0.633). CONCLUSION: Although IgE does not necessarily reflect the disease activity, IgE might be useful for the diagnosis of AIP in an inactive stage. | Kenji Hirano Minoru Tada Hiroyuki Isayama Kazumichi Kawakubo Hiroshi Yagioka Takashi Sasaki Hirofumi Kogure Yousuke Nakai Naoki Sasahira Takeshi Tsujino Nobuo Toda Kazuhiko Koike | 2010 | World Journal of Gastroenterology2010，16，41： | 4 |

| 9 | Influence of Separated Vortex on Aerodynamic Noise of an Airfoil Blade显示文摘In order to clarify the mechanism by which aerodynamic noise is generated from separated flow around an airfoil blade,the relation between the attack angle and the aerodynamic noise of the blade was analyzed using a wind tunnel experiment and a CFD code.In the case of rear surface separation,the separated vortex which has a large-scale structure in the direction of the blade chord is transformed into a structure that concentrates at the trailing edge with an increase in the attack angle.The aerodynamic noise level then becomes small according to the vortex scale in the blade chord.When the flow is separated at the leading edge,a separated vortex of low pressure is formed at the vicinity of the trailing edge.The pressure fluctuations on the blade surface at the vicinity of the trailing edge become large due to the vortex in the wake.It is considered that the aerodynamic noise level increases when the flow is separated at the leading edge because the separated vortex is causing the fluctuations due to wake vortex shedding. | Soichi Sasaki Hajime Takamatsu Masao Tsujino Haruhiro Tsubota Hidechito Hayashi | 2010 | Journal of Thermal Science2010，19，1： | 2 |
