Construction of molecular typing in LIHC microenvironment based on lipid metabolism-related genes.

Consensus on the stage of liver hepatocellular carcinoma (LIHC) in patients is difficult, which restricts the diagnosis and treatment of liver cancer. Molecular typing based on genes related to the lipid metabolism pathways can reflect deeper characteristics of liver cancer and complement the deficiency of the clinical staging system. In this study, we constructed and verified two cell subtypes: C1 and C2 in LIHC, based on six lipid metabolic pathway-associated genes identified in two independent external validation cohorts comprising single-cell RNA-sequencing technology (scRNA-Seq) data and bulk RNA-seq data downloaded from Gene Expression Omnibus (GEO) database and The Cancer Genome Atlas (TCGA) database.

Dynamic characteristics of COVID-19 infection in Chinese children.

From the start of the coronavirus disease 2019 (COVID-19) pandemic in 2020, COVID-19 infection in the pediatric population has aroused great attention. This article presents dynamic epidemiological characteristics of COVID-19 infection in pediatric patients from January 2020 to March 2022 in China. These data contributed essential insights and shared experience on the management of COVID-19 in children.

The connectome from the cerebral cortex to skeletal muscle using viral transneuronal tracers: a review.

Connectomics has developed from an initial observation under an electron microscope to the present well-known medical imaging research approach. The emergence of the most popular transneuronal tracers has further advanced connectomics research. Researchers use the virus trans-nerve tracing method to trace the whole brain, mark the brain nerve circuit and nerve connection structure, and construct a complete nerve conduction pathway.
