| 1 | Pulmonary tumor thrombotic microangiopathy of hepatocellular carcinoma: A case report and review of literature显示文摘BACKGROUND Pulmonary tumor thrombotic microangiopathy(PTTM)is a rare condition in patients with hepatocellular carcinoma(HCC);to date,few cases have been reported.While hepatic dysfunction has been focused on the later stages of HCC,the management of symptoms in PTTM is important for supportive care of the cases.For the better understanding of PTTM in HCC,the information of our recent case and reported cases have been summarized.CASE SUMMARY A patient with HCC exhibited acute and severe respiratory failure.Radiography and computed tomography of the chest revealed the multiple metastatic tumors and a frosted glass–like shadow with no evidence of infectious pneumonia.We diagnosed his condition as acute respiratory distress syndrome caused by the lung metastases and involvement of the pulmonary vessels by tumor thrombus.Administration of prednisolone to alleviate the diffuse alveolar damages including edematous changes of alveolar wall caused by the tumor cell infiltration and ischemia showed mild improvement in his symptoms and imaging findings.An autopsy showed the typical pattern of PTTM in the lung with multiple metastases.CONCLUSION PTTM is caused by tumor thrombi in the arteries and thickening of the pulmonary arterial endothelium leading to the symptoms of dyspnea in terminal staged patients.Therefore,supportive management of symptoms is necessary in the cases with PTTM and hence we believe that the information presented here is of great significance for the diagnosis and management of symptoms of PTTM with HCC. | Shinichi Morita Kenya Kamimura Hiroyuki Abe Yukari Watanabe-Mori Chiyumi Oda Takamasa Kobayashi Yoshihisa Arao Yusuke Tani Riuko Ohashi Yoichi Ajioka Shuji Terai | 2019 | World Journal of Gastroenterology2019，25，48： | 4 |

| 3 | Aldehyde dehydrogenase activity helps identify a subpopulation of murine adipose-derived stem cells with enhanced adipogenic and osteogenic differentiation potential显示文摘AIM To identify and characterize functionally distinct subpopulation of adipose-derived stem cells(ADSCs).METHODS ADSCs cultured from mouse subcutaneous adipose tissue were sorted fluorescence-activated cell sorter based on aldehyde dehydrogenase(ALDH) activity, a widely used stem cell marker. Differentiation potentials were analyzed by utilizing immunocytofluorescece and its quantitative analysis.RESULTS Approximately 15% of bulk ADSCs showed high ALDH activity in flow cytometric analysis. Although significant difference was not seen in proliferation capacity, the adipogenic and osteogenic differentiation capacity was higher in ALDHHi subpopulations than in ALDHLo. Gene set enrichment analysis revealed that ribosome-related gene sets were enriched in the ALDHHi subpopulation. CONCLUSION High ALDH activity is a useful marker for identifying functionally different subpopulations in murine ADSCs. Additionally, we suggested the importance of ribosome for differentiation of ADSCs by gene set enrichment analysis. | Harumichi Itoh Shimpei Nishikawa Tomoya Haraguchi Yu Arikawa Shotaro Eto Masato Hiyama Toshie Iseri Yoshiki Itoh Munekazu Nakaichi Yusuke Sakai Kenji Tani Yasuho Taura Kazuhito Itamoto | 2017 | World Journal of Stem Cells2017，9，10： | 1 |
| 4 | Lymphocyte-to-monocyte ratio is a short-term predictive marker of ulcerative colitis after induction of advanced therapy显示文摘Advanced therapies for patients with mild-to-severe ulcerative colitis(UC)may result in treatment failure.We examined whether the lymphocyte-to-monocyte ratio(L/M ratio)could predict the failure of advanced therapies.This retrospective,observational,cohort study included 73 patients who were treated with advanced therapies at the Hamamatsu University School of Medicine(Shizuoka,Japan)between February 2011 and November 2020.The patients were divided into the nonfailure and failure groups,and their leukocyte counts and ratios before induction were examined.Univariate and multivariate analyses were performed to identify the prognostic factors.Advanced therapies failed within 3 months in 15(20.5%)patients.Only the L/M ratio was significantly lower in the failure group than in the non-failure group(P=0.004).Receiveroperating characteristic(ROC)curve analysis revealed that an L/M ratio of ≤3.417 was predictive of treatment failure;the area under the curve(AUC)was 0.747(95%CI,0.620–0.874).Kaplan–Meier analysis revealed that the failure-free rate was significantly lower in the group with an L/M ratio of≤3.417 than in the group with an L/M ratio of>3.417(log-rank test P=0.002).Cox proportional hazard regression analysis identified an L/M ratio of≤3.417 as an independent risk factor for failure within 3 months after the induction of advanced therapies.Furthermore,ROC analysis of patients who did not receive immunomodulators also revealed that the cut-off L/M ratio was 3.417 and the AUC was 0.796(95%CI,0.666–0.925).In patients receiving advanced therapies for active UC,the L/M ratio can predict treatment failure within 3 months.L/M ratios could facilitate the transition from advanced therapies to subsequent treatments. | Natsuki Ishida Yusuke Asai Takahiro Miyazu Satoshi Tamura Shinya Tani Mihoko Yamade Moriya Iwaizumi Yasushi Hamaya Satoshi Osawa Takahisa Furuta Ken Sugimoto | 2022 | Gastroenterology Report2022，10，1： | 0 |
| 5 | Intrahepatic cholangiocarcinoma in patients with primary sclerosing cholangitis and ulcerative colitis: Two case reports显示文摘BACKGROUND Primary sclerosing cholangitis(PSC)is an extraintestinal manifestation of ulcerative colitis(UC).PSC is a well-known risk factor for intrahepatic cholangiocarcinoma(ICC),and ICC is known to have a poor prognosis.CASE SUMMARY We present two cases of ICC in patients with PSC associated with UC.In the first case,a tumor was found by magnetic resonance imaging(MRI)in the liver of a patient with PSC and UC who presented to our hospital with right-sided rib pain.The second patient was asymptomatic,but we unexpectedly detected two liver tumors in an MRI performed to evaluate bile duct stenosis associated with PSC.ICC was strongly suspected by computed tomography and MRI in both cases,and surgery was performed,but unfortunately,the first patient died of ICC recurrence 16 mo postoperatively,and the second patient died of liver failure 14 mo postoperatively.CONCLUSION Careful follow-up of patients with UC and PSC with imaging and blood tests is necessary for early detection of ICC. | Takahiro Miyazu Natsuki Ishida Yusuke Asai Satoshi Tamura Shinya Tani Mihoko Yamade Moriya Iwaizumi Yasushi Hamaya Satoshi Osawa Satoshi Baba Ken Sugimoto | 2023 | World Journal of Gastrointestinal Surgery2023，15，6： | 0 |
| 6 | Comparison of fecal calprotectin levels and endoscopic scores for predicting relapse in patients with ulcerative colitis in remission显示文摘BACKGROUND Although the usefulness of endoscopic scores,such as the Mayo Endoscopic Subscore(MES),Ulcerative Colitis Endoscopic Index of Severity(UCEIS),and Ulcerative Colitis Colonoscopic Index of Severity(UCCIS),and biomarkers such as fecal calprotectin(FC)for predicting relapse in ulcerative colitis(UC)has been reported,few studies have included endoscopic scores for evaluating the entire colon.AIM To compare the usefulness of FC value and MES,UCEIS,and UCCIS for predicting relapse in patients with UC in clinical remission.METHODS In total,75 patients with UC in clinical and endoscopic remission who visited our institution between February 2019 and March 2022 were enrolled.The diagnosis of UC was confirmed based on the clinical presentation,endoscopic findings,and histology,according to the current established criteria for UC.Fecal samples were collected the day before or after the colonoscopy for measurement of FC.Endoscopic evaluations were performed using MES,UCEIS,and UCCIS.The primary outcome measure of this study was the assessment of the association between relapse within 12 mo and MES,UCEIS,UCCIS,and FC.The secondary outcome was the comparison between endoscopic scores and biomarkers in en-rolled patients with UC with mucosal healing.RESULTSFC and UCCIS showed a significant correlation with UCEIS (r = 0.537, P < 0.001 and r = 0.957, P < 0.001, respectively).Receiver-operating characteristic analysis for predicting MES 0 showed that the area under the curve ofUCCIS was significantly higher than that of FC (P < 0.01). During the 1-year observation period, 18 (24%) patientsexperienced a relapse, and both the FC and UCCIS of the relapse group were significantly higher than that of theremission group. The cut-off values for predicting relapse were set at FC = 323 mg/kg and UCCIS = 10.2. The areaunder the curve of the receiver-operating characteristic analysis for predicting relapse did not show a significantdifference between FC and UCCIS. The accuracy of the endoscopic scores and biomarkers in predicting relapse was86.7% for UCCIS, 85.3% for UCEIS, 76.0% for FC, and 73.3% for MES.CONCLUSIONThe three endoscopic scores and FC may predict UC relapse during clinical remission. Among these scores, UCEISmay be the most useful in terms of ease of evaluation and accuracy. | Natsuki Ishida Tatsuhiro Ito Kenichi Takahashi Yusuke Asai Takahiro Miyazu Tomohiro Higuchi Satoshi Tamura Shinya Tani Mihoko Yamade Moriya Iwaizumi Yasushi Hamaya Satoshi Osawa Ken Sugimoto | 2023 | World Journal of Gastroenterology2023，29，47： | 0 |
