AI Article Synopsis
- Optimized New Shengmai Powder (ONSMP) is a traditional Chinese medicine used to treat heart failure, targeting the MAPK signaling pathway, which plays a crucial role in myocardial fibrosis.
- The study aimed to assess the effectiveness of ONSMP in reducing myocardial fibrosis and its mechanisms by using a rat model of heart failure and various clinical tests.
- Results showed that ONSMP consists of key active components (isorhamnetin, kaempferol, quercetin, and tanshinone ⅡA) and significantly improved heart function and reduced fibrosis by inhibiting MAPK signaling pathway activation in the rat model.
Article Abstract
Ethnopharmacological Relevance: Optimized New Shengmai Powder (ONSMP) is a traditional Chinese medicine (TCM) formula for heart failure treatment. MAPK signaling pathway is the key driver of myocardial fibrosis in heart failure. However, the mechanism of ONSMP on myocardial fibrosis and MAPK signaling pathway remains unclear.
Aim Of The Study: To evaluate the effect of ONSMP against myocardial fibrosis in heart failure and the underlying mechanisms.
Materials And Methods: Firstly, UHPLC-Q-Exactive-MS/MS was used to identify the active components in ONSMP. Secondly, a rat model of heart failure was established by ligating the left anterior descending branch of the coronary artery. After four weeks of intragastric administration of ONSMP, we used various classic tests, including echocardiography, exhaustive swimming, cardiopulmonary coefficient, heart failure markers, and cardiac pathological section, to assess the prescription's anti-myocardial fibrosis in heart failure properties. AGEs, Ang Ⅱ, VEGF, CTGF, and TGFβ levels in rat serum were quantified using ELISA. The positive expression of p-ERK1/2 and p-JNK1/2 of rat myocardium was determined immunohistochemical. The protein and mRNA levels of genes involved in the MAPK signaling pathway and myocardial fibrosis were measured using western blotting or real-time PCR.
Results: The main components of ONSMP that regulate the MAPK signaling pathway are isorhamnetin, kaempferol, quercetin, and tanshinone ⅡA. ONSMP ameliorated cardiac function and exercise tolerance and reduced cardiopulmonary coefficient, heart failure marker levels, and myocardial fibrosis in the heart failure rats. In addition, ONSMP diminished the serum MAPK pathway activator levels, positive expression level of p-ERK1/2 and p-JNK1/2, protein and mRNA levels of components of the MAPK signaling pathway in the myocardial tissue of heart failure rat, indicating that it inhibits MAPK signaling pathway.
Conclusions: ONSMP delayed heart failure by inhibiting myocardial fibrosis via the MAPK signaling pathway.

Enhanced glycolysis and elevated lactic acid (LA) production are observed during sudden death syndrome (SDS) in broilers. However, the mechanism underlying LA-induced cardiomyocyte damage and heart failure in fast-growing broilers remains unclear. In this study, chicken embryo cardiomyocytes (CECs) were cultured and treated with LA to investigate LA-induced CEC injury and its mechanism, aiming to develop strategies to prevent LA-induced SDS in broilers.

Background: With the growing number of high-risk pregnant women, echocardiography frequently reveals pericardial effusion (PE). However, the clinical implications of PE are unknown.
Method: We analyzed a cohort of 406 high-risk pregnant women who underwent echocardiography in the third trimester between November 2019 and December 2022.

Assessing myocardial viability is crucial for managing ischemic heart disease. While late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) is the gold standard for viability evaluation, it has limitations, including contraindications in patients with renal dysfunction and lengthy scan times. This study investigates the potential of non-contrast CMR techniques-feature tracking strain analysis and T1/T2 mapping-combined with machine learning (ML) models, as an alternative to LGE-CMR for myocardial viability assessment.

Background: Glucagon-like peptide-1 receptor agonist (GLP-1RA) treatment reduces cardiovascular events in type 2 diabetes. Yet, the impact of GLP-1RA treatment before ST-segment elevation myocardial infarction (STEMI) on long-term prognosis in patients with type 2 diabetes remains unclear. In patients with STEMI and type 2 diabetes, we aimed to investigate the association between long-term prognosis and GLP-1RA treatment before STEMI.
