CircRNA-mediated pathology: a new preliminary insight into the mechanism of type II cardio-renal syndrome.

Aim: The aim of this research was to investigate the expression of peripheral blood circular RNA (circRNA) in patients with type II cardio-renal syndrome, uncover the potential function and possible mechanisms mediated by circRNAs, and ultimately provide gene target support for the treatment of type II cardio-renal syndrome.

Methods: CircRNAs in the peripheral blood from five healthy individuals and 20 type II cardio-renal syndrome patients were collected for micro-array analysis. Another cohort study consisting of 12 normal cases and 15 type II cardiorenal syndrome patients was conducted to verify the chosen circRNA by quantitative real-time polymerase chain reaction.

The Role of Myocardial Mitochondrial Quality Control in Heart Failure.

At present, the treatment of heart failure has entered the plateau phase, and it is necessary to thoroughly study the pathogenesis of heart failure and find out the corresponding treatment methods. Myocardial mitochondria is the main site of cardiac energy metabolism, whose dysfunction is an important factor leading to cardiac dysfunction and heart failure. Mitochondria are highly dynamic organelles.

Xin Fu Kang oral liquid inhibits excessive myocardial mitophagy in a rat model of advanced heart failure.

Heart failure caused by myocardial infarction is a common cardiovascular disease with high mortality rate. Myocardial mitophagy is involved in the process of occurrence and development of heart failure. In this study, we aimed to investigate the effects of Xin Fu Kang (XFK) oral liquid on myocardial mitophagy in a rat model of advanced heart failure.

Deficiency of interfibrillar mitochondria in post-acute myocardial infarction heart failure.

Mitochondrial dysfunction plays an important role in the progress of heart failure (HF). A pronounced variability of defects in mitochondrial subpopulations is reported to occur in various disease models. The aim of the study was to define the defects in the ultra structure and bioenergetic function of cardiac mitochondria in acute myocardial infarction-induced HF.

The relationship between neutrophil to lymphocyte ratio and artery stiffness in subtypes of hypertension.

Recently, neutrophil/lymphocyte ratio (NLR) has been proved to be a useful indicator of inflammation and cardiovascular risk. Brachial-ankle pulse wave velocity is an indicator for early atherosclerotic changes. It is unknown whether NLR differs in subtypes of hypertension, and little research has been performed on the relationship between NLR and arteriosclerosis in subtypes of hypertension.

[Endoplasmic reticulum stress and vascular endothelial cell apoptosis].

Endoplasmic reticulum stress (ERS) is a new pathway of apoptosis following the discovery of death receptor signaling pathway and mitochondrial pathway. By activating the unfolded protein response (UPR), ERS can suspend protein synthesis, restore the endoplasmic reticulum homeostasis, and thus play a protective role for cells; however, if the inducing factors of ERS persist, ERS will continue to trigger C/EBP homologous protein, JNK, caspase, or other pathways to induce apoptosis. In addition, the injury and apoptosis of vascular endothelial cells are key links in various diseases and pathophysiologic processes, and research has also shown that vascular endothelial cell apoptosis is closely related with the ERS.
