Background and Aims:The clinical introduction of hepcidin25(Hep25)has led to a more detailed understanding of its relationship with ferroportin(FP)and divalent metal transporter1 in primary iron overload syndromes(PIOSs).In 2012,we proposed a classification of PIOSs based on the Hep25/FP system,which consists of prehepatic aceruloplasminemia,hepatic hemochromatosis(HC),and posthepatic FP disease(FP-D).However,in consideration of accumulated evidence on PIOSs,we aimed to renew the ***:We reviewed the 2012 classification and retrospectively renewed it according to new information on ***:Iron-loading anemia was included in PIOSs as a prehepatic form because of the newly discovered erythroferrone-induced suppression of Hep25,and the state of traditional FP-D was remodeled as the BIOIRON *** key molecules responsible for prehepatic PIOSs are low transferrin saturation in aceruloplasminemia and increased erythroferrone production by erythroblasts in iron-loading *** PIOSs comprise four genotypes of HC,in each of which the synthesis of Hep25 is inappropriately reduced in the *** Hep25 synthesis is adequate in posthepatic PIOSs;however,two mutant FP molecules may resist Hep25 differently,resulting in SLC40A1-HC and FP-D,*** phenotypes are diagnosed using laboratory tests,including circulating Hep25,followed by suitable *** sequencing of the candidate genes may be outsourced to gene centers when *** kits for the prevalent mutations,such as C282Y,may be the first choice for a genetic analysis of HC in ***:The revised classification may be useful worldwide.

This editorial comments on the article“Efficacy of multi-slice spiral computed tomography in evaluating gastric cancer recurrence after endoscopic submucosal dissection”.We focus on the importance of paying more attention to postendoscopic submucosal dissection(ESD)gastric cancer recurrence in patients with early gastric cancer(EGC)and how to manage it *** has been a wellknown treatment and the mainstay for EGC,with the advantages of less invasion and fewer complications when compared with traditional surgical *** a lower local recurrence rate after ESD,the problem of postoperative recurrence in patients with EGC has become increasingly non-ignorable with the global popularization of ESD technology and the increasing number of post-ESD patients.
