Abstract
Despite extensive scientific efforts directed toward the evolutionary trajectory of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in humans at the beginning of the COVID-19 epidemic, it remains unclear how the virus jumped into and evolved in humans so far. Herein, we recruited almost all adult coronavirus disease 2019 (COVID-19) cases appeared locally or imported from abroad during the first 8 months of the outbreak in Shanghai. From these patients, SARS-CoV-2 genomes occupying the important phylogenetic positions in the virus phylogeny were recovered. Phylogenetic and mutational landscape analyses of viral genomes recovered here and those collected in and outside of China revealed that all known SARS-CoV-2 variants exhibited the evolutionary continuity despite the co-circulation of multiple lineages during the early period of the epidemic. Various mutations have driven the rapid SARS-CoV-2 diversification, and some of them favor its better adaptation and circulation in humans, which may have determined the waxing and waning of various lineages.

Abstract
Hyperglycaemia causes impairment of osteogenic differentiation and accelerates stem cell senescence, resulting in weakened osteogenesis and disordered bone metabolism. Phytic acid (PA) is an antioxidant that is reportedly beneficial to bone homeostasis. The present study aims to clarify how PA affects the osteogenic capacity and cellular senescence of bone marrow mesenchymal stem cells (BMSCs) exposed to high-glucose environments, as well as the potential molecular mechanisms. Our results indicate that osteogenic differentiation in BMSCs cultivated in high-glucose conditions is enhanced by PA, as evidenced by increased alkaline phosphatase activity and staining, Alizarin Red S staining, osteogenic marker in in vitro studies, and increased osteogenesis in animal experiments. PA also prevented high-glucose-induced senescence of BMSCs, as evidenced by the repression of reactive oxygen species production, senescence-associated β-galactosidase staining, and P21 and P53 expression. Furthermore, it was found that PA rescued the high-glucose-inhibited expression of phosphorylated extracellular regulated protein kinases (p-ERK). The inhibition of ERK pathway by the specific inhibitor PD98059 blocked the PA-enhanced osteogenesis of BMSCs and promoted cell senescence. Our results revealed that PA enhances osteogenic differentiation and inhibits BMSC senescence in a high-glucose environment. In addition, the activation of the ERK pathway seems to mediate the beneficial effects of PA. The findings provide novel insights that could facilitate bone regeneration in patients with diabetes.

Abstract
Bats, rodents, and shrews are the most important animal sources of human infectious diseases. However, the evolution and transmission of viruses among them remain largely unexplored. Through the meta-transcriptomic sequencing of internal organ and fecal samples from 2,443 wild bats, rodents, and shrews sampled from four Chinese habitats, we identified 669 viruses, including 534 novel viruses, thereby greatly expanding the mammalian virome. Our analysis revealed high levels of phylogenetic diversity, identified cross-species virus transmission events, elucidated virus origins, and identified cases of invertebrate viruses in mammalian hosts. Host order and sample size were the most important factors impacting virome composition and patterns of virus spillover. Shrews harbored a high richness of viruses, including many invertebrate-associated viruses with multi-organ distributions, whereas rodents carried viruses with a greater capacity for host jumping. These data highlight the remarkable diversity of mammalian viruses in local habitats and their ability to emerge in new hosts.

Abstract
GRAS transcription factors belong to the plant-specific protein family. They are not only involved in plant growth and development but also in plant responses to a variety of abiotic stresses. However, to date, the SCL32(SCARECROW-like 32) gene conferring the desired resistance to salt stresses has not been reported in plants. Here, ThSCL32, a homologous gene of ArabidopsisthalianaAtSCL32, was identified. ThSCL32 was highly induced by salt stress in Tamarix hispida. ThSCL32 overexpression in T. hispida gave rise to improved salt tolerance. ThSCL32-silenced T. hispida plants were more sensitive to salt stress. RNA-seq analysis of transient transgenic T. hispida overexpressing ThSCL32 revealed significantly enhanced ThPHD3 (prolyl-4-hydroxylase domain 3 protein) gene expression. ChIP-PCR further verified that ThSCL32 probably binds to the novel cis-element SBS (ACGTTG) in the promoter of ThPHD3 to activate its expression. In brief, our results suggest that the ThSCL32 transcription factor is involved in salt tolerance in T. hispida by enhancing ThPHD3 expression.

Abstract
Over the last several decades, no emerging virus has had a profound impact on the world as the SARS-CoV-2 that emerged at the end of 2019 has done. To know where severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) originated from and how it jumped into human population, we immediately started a surveillance investigation in wild mammals in and around Wuhan when we determined the agent. Herein, coronaviruses were screened in the lung, liver, and intestinal tissue samples from fifteen raccoon dogs, seven Siberian weasels, three hog badgers, and three Reeves’s muntjacs collected in Wuhan and 334 bats collected around Wuhan. Consequently, eight alphacoronaviruses were identified in raccoon dogs, while nine betacoronaviruses were found in bats. Notably, the newly discovered alphacoronaviruses shared a high whole-genome sequence similarity (97.9 per cent) with the canine coronavirus (CCoV) strain 2020/7 sampled from domestic dog in the UK. Some betacoronaviruses identified here were closely related to previously known bat SARS-CoV-related viruses sampled from Hubei province and its neighbors, while the remaining betacoronaviruses exhibited a close evolutionary relationship with SARS-CoV-related bat viruses in the RdRp gene tree and clustered together with SARS-CoV-2-related bat coronaviruses in the M, N and S gene trees, but with relatively low similarity. Additionally, these newly discovered betacoronaviruses seem unlikely to bind angiotensin-converting enzyme 2 because of the deletions in the two key regions of their receptor-binding motifs. Finally, we did not find SARS-CoV-2 or its progenitor virus in these animal samples. Due to the high circulation of CCoVs in raccoon dogs in Wuhan, more scientific efforts are warranted to better understand their diversity and evolution in China and the possibility of a potential human agent.

Abstract
Hydrogen production through artificial photosynthesis has been regarded as a promising strategy for dealing with energy shortage and environmental problems. In this work, graphdiyne (GD) was first introduced to the visible-light catalytic system for hydrogen production, in which a CdS/GD heterojunction was prepared through a simple in situ growth process by adding Cd(AcO)2 into a dimethyl sulfoxide (DMSO) solution containing GD substrate. The as-prepared CdS/GD heterojunction exhibits much higher performance for photocatalytic hydrogen evolution compared to that of pristine GD and CdS nanoparticles. The photocatalytic performance of CdS/GD heterostructure containing 2.5 wt % of GD (GD2.5) is 2.6 times higher than that of the pristine CdS nanoparticles. The enhanced catalytic performance can be ascribed to the formation of CdS/GD heterojunction, in which the presence of GD can not only stabilize CdS nanoparticles by preventing the agglomeration of CdS nanoparticles but also act as a photogenerated hole transfer material for efficiently separating photogenerated electron-hole pairs in CdS. Accordingly, this work provides the potential of GD-derived materials for solar energy conversion and storage.

Abstract
Objective:To investigate the mutation characteristics of GJB6 (gap juction bata 6) gene in 318 Han Chinese pedigrees with non-syndromic hearing loss.Method:Polymerase chain reaction was used to detect the coding region of GJB6 gene in 318 Han Chinese pedigrees with non-syndromic hearing loss.Gene arrays and second generation sequencing were used to detect 118 genes which had reported to be accosiated with deafness in members of pedigree which possibly carried pathogenic GJB6 gene mutation.Result:Here,we have screened the mutations of GJB6 gene in 318 Han Chinese pedigrees with non-syndromic hearing loss and found one pedigree carrying both GJB6 and GJB2 gene deletion.Clinical and molecular genetic evaluation revealed the variable phenotype of hearing impairments including age-at-onset,audiometric configuration and severity in these subjects.Mutational analysis of the GJB2 and GJB6 gene coding region showed a heterozygous 235 del C of GJB2 gene and a novel 228 del G of GJB6 gene.Conclusion:GJB6 gene 228 del G variant,which occurs at a highly evolutionarily conserved nucleotide,forward the stop codon to 81 position and result in the corresponding polypeptide 181 amino acids shorter than wildtype polypeptide.In addition,GJB6 gene 228 del G absent varies among 94 unrelated Chinese controls.Our finding suggest that GJB6 gene 228 del G maybe a novel pathogenic mutation associated with non-syndromic hearing loss.
