The aim of this study is to explore a novel classification and investigate the clinical significance of hepatocellular carcinoma (HCC) cells. We analyzed integrated single-cell RNA sequencing and bulk RNA-seq data obtained from HCC samples. Cell trajectory analysis divided HCC cells into three subgroups with different differentiation states: state 1 was closely related to phosphoric ester hydrolase activity, state 2 was involved in eukaryotic initiation factor 4E binding, translation regulator activity and ribosome, and state 3 was associated with oxidoreductase activity and metabolism. Three molecular classes based on HCC differentiation-related genes (HDRGs) from HCC samples were identified, which revealed immune checkpoint gene expression and overall survival (OS) of HCC patients. Moreover, a prognostic risk scoring (RS) model was generated based on eight HDRGs, and the results showed that the OS of the high-risk group was worse than that of the low-risk group. Further, potential therapeutic drugs were screened out based on eight prognostic RS-HDRGs. This study highlights the importance of HCC cell differentiation in immunotherapy, clinical prognosis, and potential molecular-targeted drugs for HCC patients, and proposes a direction for the development of individualized treatments for HCC.

Designing a superior micro–nano structure is conducive to boosting the capacitance performance of electroactive materials. Herein, the three-dimensional NiCo2O4 hierarchical nanosheet-wire composite structure (NiCo2O4 HNSW) was fabricated by a one-step hydrothermal process followed by calcination. The hierarchical structure consisted of numerous nanowires grown at the end of nanosheets. The unique nanosheet-wire structure can enlarge the contact area between the electrode and electrolyte, accelerate electron transport, expose more active sites, and accelerate the diffusion of the electrolyte ions. The NiCo2O4 HNSW electrode displayed an impressive specific capacity of 992.8 C g−1 at 1 A g−1 and demonstrated an outstanding capacity retention of 70.1% at 20 A g−1 for 12 000 charge–discharge cycles. The hybrid supercapacitor demonstrated an energy density of 44.3 W h kg−1 at a power density of 800 W kg−1. [ABSTRACT FROM AUTHOR]

SRS (SHI-related sequence) transcription factors play a crucial role in plant growth, development, and abiotic stress response. Although Brassica napus (B. napus) is one of the most important oil crops in the world, the role of SRS genes in B. napus (BnSRS) has not been well investigated. Therefore, we employed a bioinformatics approach to identify BnSRS genes from genomic data and investigated their characteristics, functions, and expression patterns, to gain a better understanding of how this gene family is involved in plant development and growth. The results revealed that there were 34 BnSRS gene family members in the genomic sequence of B. napus, unevenly distributed throughout the sequence. Based on the phylogenetic analysis, these BnSRS genes could be divided into four subgroups, with each group sharing comparable conserved motifs and gene structure. Analysis of the upstream promoter region showed that BnSRS genes may regulate hormone responses, biotic and abiotic stress response, growth, and development in B. napus. The protein-protein interaction analysis revealed the involvement of BnSRS genes in various biological processes and metabolic pathways. Our analysis of BnSRS gene expression showed that 23 BnSRS genes in the callus tissue exhibited a dominant expression pattern, suggesting their critical involvement in cell dedifferentiation, cell division, and tissue development. In addition, association analysis between genotype and agronomic traits revealed that BnSRS genes may be linked to some important agronomic traits in B. napus, suggesting that BnSRS genes were widely involved in the regulation of important agronomic traits (including C16.0, C18.0, C18.1, C18.2 C18.3, C20.1, C22.1, GLU, protein, TSW, and FFT). In this study, we predicted the evolutionary relationships and potential functions of BnSRS gene family members, providing a basis for the development of BnSRS gene functions which could facilitate targeted functional studies and genetic improvement for elite breeding in B. napus.

At present, there is no unified construction standards for the training conditions of emergency rescue technology specialty, vocational colleges have no standards to follow during the construction of training rooms, resulting in unreasonable construction planning of training rooms, great randomness, simple training projects and weak practicability, etc. By analyzing the training experience of foreign emergency rescue knowledge and skills, based on the curriculum system of emergency rescue technology specialty, a set of construction standards for the training rooms of emergency rescue technology specialty with the main line of "integration of courses and certificates, focusing on practical combat" is constructed to fill the gap in the construction standards of training rooms of emergency rescue technology specialty.
