The coronavirus disease 2019(COVID-19)pandemic has become a global health crisis.[1,2]Healthcare workers play key roles during the pandemic,but a serious shortage of personnel may occur at peak *** order to control the rapid spreading of an outbreak,adequate staffing is needed to manage infected patients and to prevent infections of surrounding patients,staff members,as well as the local community.[3]Although there are multiple modes for the organization and deployment of medical staff to deal with the rapidly increasing population of COVID-19 patients,successful experiences from Wuhan,China may prove helpful as a model for effectively dealing with this urgent situation.

Histone H3 Lys36(H3K36)methylation and its associated modifiers are crucial for DNA double-strand break(DSB)repair,but the mechanism governing whether and how different H3K36 methylation forms impact repair pathways is ***,we unveil the distinct roles of H3K36 dimethylation(H3K36me2)and H3K36 trimethylation(H3K36me3)in DSB repair via non-homologous end joining(NHEJ)or homologous recombination(HR).Yeast cells lacking H3K36me2 or H3K36me3 exhibit reduced NHEJ or HR efficiency.y Ku70 and Rfa1 bind H3K36me2-or H3K36me3-modified peptides and chromatin,*** these interactions impairs y Ku70 and Rfa1 recruitment to damaged H3K36me2-or H3K36me3-rich loci,increasing DNA damage sensitivity and decreasing repair ***,H3K36me2-enriched intergenic regions and H3K36me3-enriched gene bodies independently recruit y Ku70 or Rfa1 under DSB ***,human KU70 and RPA1,the homologs of y Ku70 and Rfa1,exclusively associate with H3K36me2 and H3K36me3 in a conserved *** findings provide valuable insights into how H3K36me2 and H3K36me3 regulate distinct DSB repair pathways,highlighting H3K36 methylation as a critical element in the choice of DSB repair pathway.

Clinical outcomes are positively associated with hematoma *** monocyte-macrophage scavenger receptor,CD163,plays an important role in the metabolism of hemoglobin,and a soluble form of CD163 is present in plasma and other tissue fluids;therefore,we speculated that serum CD163 affects hematoma absorption after intracerebral *** with intracerebral hemorrhage were divided into high-and low-level groups according to the average CD163 level（1,977.79 ± 832.91 ng/m L）.Compared with the high-level group,the low-level group had a significantly slower hematoma absorption rate,and significantly increased National Institutes of Health Stroke Scale scores and modified Rankin Scale *** results suggest that CD163 promotes hematoma absorption and the recovery of neurological function in patients with intracerebral hemorrhage.
