| 1 | Measurement of prostaglandin metabolites is useful in diagnosis of small bowel ulcerations显示文摘BACKGROUND We recently reported on a hereditary enteropathy associated with a gene encoding a prostaglandin transporter and referred to as chronic enteropathy associated with SLCO2 A1 gene(CEAS). Crohn's disease(CD) is a major differential diagnosis of CEAS, because these diseases share some clinical features. Therefore, there is a need to develop a convenient screening test to distinguish CEAS from CD.AIM To examine whether prostaglandin E major urinary metabolites(PGE-MUM) can serve as a biomarker to distinguish CEAS from CD.METHODS This was a transactional study of 20 patients with CEAS and 98 patients with CD.CEAS was diagnosed by the confirmation of homozygous or compound heterozygous mutation of SLCO2 A1. We measured the concentration of PGEMUM in spot urine by radioimmunoassay, and the concentration was compared between the two groups of patients. We also determined the optimal cut-off value of PGE-MUM to distinguish CEAS from CD by receiver operating characteristic(ROC) curve analysis.RESULTS Twenty Japanese patients with CEAS and 98 patients with CD were enrolled.PGE-MUM concentration in patients with CEAS was significantly higher than that in patients with CD(median 102.7 vs 27.9 μg/g × Cre, P < 0.0001). One log unit increase in PGE-MUM contributed to 7.3 increase in the likelihood for the diagnosis of CEAS [95% confidence interval(CI) 3.2-16.7]. A logistic regression analysis revealed that the association was significant even after adjusting confounding factors(adjusted odds ratio 29.6, 95%CI 4.7-185.7). ROC curve analysis revealed the optimal PGE-MUM cut-off value for the distinction of CEAS from CD to be 48.9 μg/g × Cre with 95.0% sensitivity and 79.6% specificity.CONCLUSION PGE-MUM measurement is a convenient, non-invasive and useful test for the distinction of CEAS from CD. | Yuichi Matsuno Junji Umeno Motohiro Esaki Yoichiro Hirakawa Yuta Fuyuno Yasuharu Okamoto Atsushi Hirano Shigeyoshi Yasukawa Fumihito Hirai Toshiyuki Matsui Shuhei Hosomi Kenji Watanabe Naoki Hosoe Haruhiko Ogata Tadakazu Hisamatsu Shunichi Yanai Shuji Kochi Koichi Kurahara Tsuneyoshi Yao Takehiro Torisu Takanari Kitazono Takayuki Matsumoto | 2019 | World Journal of Gastroenterology2019，25，14： | 5 |

| 4 | Mechanism of gastrointestinal abnormal motor activity induced by cisplatin in conscious dogs显示文摘AIM: To investigate whether 5-hydroxytryptamine(serotonin; 5-HT) is involved in mediating abnormal motor activity in dogs after cisplatin administration.METHODS: After the dogs had been given a 2-wk recovery period, all of them were administered cisplatin, and the motor activity was recorded using strain gauge force transducers. Blood and intestinal fluid samples were collected to measure 5-HT for 24 h. To determine whether 5-HT in plasma or that in intestinal fluids is more closely related to abnormal motor activity we injected 5-HT into the bloodstream and the intestinal tract of the dogs.RESULTS: Cisplatin given intravenously produced abnormal motor activity that lasted up to 5 h. From 3 to 4 h after cisplatin administration, normal intact dogs exhibited retropropagation of motor activity accompanied by emesis. The concentration of 5-HT in plasma reached the peak at 4 h, and that in intestinal fluids reached the peak at 3 h. In normal intact dogs with resection of the vagus nerve that were administered kytril, cisplatin given intravenously did not produce abnormal motor activity. Intestinal serotonin administration did not produce abnormal motor activity, but intravenous serotonin administration did.CONCLUSION: After the intravenous administration of cisplatin, abnormal motor activity was produced in the involved vagus nerve and in the involved serotonergic neurons via another pathway. This study was the first to determine the relationship between 5-HT and emesis-induced motor activity. | Hiroyuki Ando Erito Mochiki Tetsuro Ohno Mitsuhiro Yanai Yoshitaka Toyomasu Kyoichi Ogata Yuichi Tabe Ryuusuke Aihara Toshihiro Nakabayashi Takayuki Asao Hiroyuki Kuwano | 2014 | World Journal of Gastroenterology2014，20，42： | 0 |
