| 1 | Osteopontin is a biomarker for early autoimmune uveoretinitis显示文摘Osteopontin(OPN)is an extracellular matrix protein with a diverse range of functions,including roles in cell adhesion,migration,and immunomodulation,which are associated with the modulation of neuroinflammation in the central nervous system.The present study was performed to evaluate the involvement of OPN in the eyes of an experimental autoimmune uveoretinitis(EAU)model.The EAU model was developed by immunization of Lewis rats with interphotoreceptor retinoid-binding protein.The results showed the OPN level was remarkably upregulated in the eye of EAU rats on day 9 post-immunization.The level of CD44,a ligand of OPN,was increased in the ciliary body of EAU rats.Furthermore,OPN was also detected in the ciliary body and activated microglia/macrophages in the EAU retina.The results suggest that OPN was significantly upregulated in the eyes of EAU rats,and that it may be useful as an early biomarker of ocular autoimmune diseases.All animal experiments were approved by the Institutional Animal Care and Use Committee of Jeju National University(approval No.2020-0012)on March 11,2020. | Jeongtae Kim Meejung Ahn Yuna Choi Jiyoon Chun Kyungsook Jung Akane Tanaka Hiroshi Matsuda Taekyun Shin | 2022 | Neural Regeneration Research2022，17，7： | 3 |
| 6 | Stage at diagnosis of colorectal cancer through diagnostic route:Who should be screened?显示文摘BACKGROUND Colorectal cancer(CRC)is a global health concern,with advanced-stage diagnoses contributing to poor prognoses.The efficacy of CRC screening has been well-established;nevertheless,a significant proportion of patients remain unscreened,with>70%of cases diagnosed outside screening.Although identifying specific subgroups for whom CRC screening should be particularly recommended is crucial owing to limited resources,the association between the diagnostic routes and identification of these subgroups has been less appreciated.In the Japanese cancer registry,the diagnostic routes for groups discovered outside of screening are primarily categorized into those with comorbidities found during hospital visits and those with CRC-related symptoms.AIM To clarify the stage at CRC diagnosis based on diagnostic routes.METHODS We conducted a retrospective observational study using a cancer registry of patients with CRC between January 2016 and December 2019 at two hospitals.The diagnostic routes were primarily classified into three groups:Cancer screening,follow-up,and symptomatic.The early-stage was defined as Stages 0 or I.Multivariate and univariate logistic regressions were exploited to determine the odds of early-stage diagnosis in the symptomatic and cancer screening groups,referencing the follow-up group.The adjusted covariates were age,sex,and tumor location.RESULTS Of the 2083 patients,715(34.4%),1064(51.1%),and 304(14.6%)belonged to the follow-up,symptomatic,and cancer screening groups,respectively.Among the 2083 patients,CRCs diagnosed at an early stage were 57.3%(410 of 715),23.9%(254 of 1064),and 59.5%(181 of 304)in the follow-up,symptomatic,and cancer screening groups,respectively.The symptomatic group exhibited a lower likelihood of early-stage diagnosis than the follow-up group[P<0.001,adjusted odds ratio(aOR),0.23;95%confidence interval(95%CI):0.19-0.29].The likelihood of diagnosis at an early stage was similar between the follow-up and cancer screening groups(P=0.493,aOR for early-stage diagnosis in the cancer screening group vs follow-up group=1.11;95%CI=0.82-1.49).CONCLUSION CRCs detected during hospital visits for comorbidities were diagnosed earlier,similar to cancer screening.CRC screening should be recommended,particularly for patients without periodical hospital visits for comorbidities. | Nobukazu Agatsuma Takahiro Utsumi Yoshitaka Nishikawa Takahiro Horimatsu Takeshi Seta Yukitaka Yamashita Yukari Tanaka Takahiro Inoue Yuki Nakanishi Takahiro Shimizu Mikako Ohno Akane Fukushima Takeo Nakayama Hiroshi Seno | 2024 | World Journal of Gastroenterology2024，30，10： | 0 |
