Dear Editor,Myelodysplastic syndromes(MDSs)are a group of clonal myeloid stem cell disorders characterized by varying degrees of cytopenias,cytogenetic and molecular genetic abnormalities,and a predisposition to acute myeloid leukemia(AML).The treatments for MDS mainly consist of cytoreductive treatment,such as traditional AML-like chemotherapy,hypomethylating agents(HMAs),allogeneic hematopoietic stem cell transplantation(alio-HSCT)and immunoregulation according to risk stratification.

Inflammation underlies many chronic diseases， and inflammatory bowel disease (IBD) is a condition characterized by long-term inflammation of the gut. Egg whites have been shown to contain many beneficial active substances. Therefore， we obtained two peptides from salted egg white: Val-Val-His-Phe (VF-4) and Asp-Thr-Gln-Ala-Met-Pro-Phe-Arg (DR-8). The sodium dextran sulfate (DSS)-induced mice colitis model was used to evaluate its regulatory effect on colitis in vivo. The results showed that VF-4 and DR-8 improved the clinical symptoms of DSS-induced colitis， attenuated colon tissue damage， inhibited the activation of NF-κB/MAPK/PI3K-AKT signaling pathways， and inhibited the expression of inflammatory cytokines. 16S rRNA gene sequencing showed that VF-4 and DR-8 administration increased the relative abundance of intestinal beneficial bacteria including Lactobacillus， Blautia， and down-regulated the relative abundance of inflammation-related bacteria including Acinetobacter， Lachnospiraceae＿NK4A136＿group， Klebsiella. Moreover， the degree of correlation between pro-inflammatory cytokines and microbiota was as follows: IL-6 > TNF-α > IL-1β > IFN-γ. In conclusion， this study suggests that salted egg white peptides VF-4 and DR-8 have a significant anti-inflammatory effect in vivo. It also provides a strategy for the treatment of inflammatory bowel disease and a new way for the high-value utilization of salted egg white.

To the Editor： Valve stenosis and regurgitation can lead to a series of symptoms, including chest distress and dyspnea. Valve replacement is an effective surgical procedure that improves patients＇ quality of life and life span and has played an increasingly important role in treating mitral valve diseases. Previous studies have reported different risk factors and independent predictors of increased mortality in patients with mitral valve replacement （MVR） and/or aortic valve replacement （AVR）. This study retrospectively reviewed data on patients undergoing valve surgery to determine the risk factors and predictors of short-term mortality in this patient population.
