Expression and Clinical Implications of pro-BNP and Soluble ST2 in Chronic Heart Failure.

Chronic heart failure (CHF) is a complex clinical syndrome resulting from various cardiac diseases, characterized by weakened cardiac pumping capacity and inadequate blood supply to body tissues. This study aims to investigate the expression and clinical implications of pro-B-type natriuretic peptide (pro-BNP) and soluble suppression of tumorigenicity 2 (sST2) in CHF to explore their potential in early diagnosis and severity assessment of the pathological condition. This study included 146 CHF patients treated at our hospital from January 2022 to December 2023, who were classified in the observation group, and 150 concurrent healthy people categorized in the control group.

Single-Cell Transcriptome Analysis Identified Core Genes and Transcription Factors in Mesenchymal Cell Differentiation during Liver Cirrhosis.

Background: Mesenchymal cells, including hepatic stellate cells (HSCs), fibroblasts (FBs), myofibroblasts (MFBs), and vascular smooth muscle cells (VSMCs), are the main cells that affect liver fibrosis and play crucial roles in maintaining tissue homeostasis. The dynamic evolution of mesenchymal cells is very important but remains to be explored for researching the reversible mechanism of hepatic fibrosis and its evolution mechanism of hepatic fibrosis to cirrhosis.

Methods: Here, we analysed the transcriptomes of more than 50,000 human single cells from three cirrhotic and three healthy liver tissue samples and the mouse hepatic mesenchymal cells of two healthy and two fibrotic livers to reconstruct the evolutionary trajectory of hepatic mesenchymal cells from a healthy to a cirrhotic state, and a subsequent integrative analysis of bulk RNA sequencing (RNA-seq) data of HSCs from quiescent to active (using transforming growth factor β1 (TGF-β1) to stimulate LX-2) to inactive states.

Sustained-release microspheres of amifostine for improved radio-protection, patient compliance, and reduced side effects.

A biweekly administration of sustained-release microsphere dosage form of amifostine, a radioprotective drug used in radiotherapy, was performed to examine the feasibility to minimize injection frequency and blood concentration-associated side effects. Model animal trials indicated that this subcutaneously injecting microspheres, 50-100 μm in diameter, achieved bi-weekly prolonged radio-protective efficacy and, at the same time, significantly reduced skin irritation than the solution form of amifostine given by the same administration route. In addition, the hypertension associated with blood concentration of amifostine was not observed in the drug-treated rats.
