The specific efficacy is manifested in:

Improve symptomsFor example, for patients with coronary heart disease and angina pectoris, traditional Chinese medicine can effectively alleviate discomfort symptoms such as chest tightness, chest pain, palpitations, shortness of breath, and fatigue;

Protecting the myocardiumSome traditional Chinese medicine ingredients, such as Astragaloside IV and Ginsenoside, have been proven to have antioxidant, anti-inflammatory, and cardiomyocyte apoptosis reducing effects, especially showing protective potential in myocardial ischemia-reperfusion injury (such as after interventional surgery);

Improve heart functionFor patients with chronic heart failure, traditional Chinese medicine can enhance cardiac contractility, reduce edema, and improve cardiac function grading through the methods of "warming yang and promoting water circulation" (such as Fuzi and Tingzi) and "tonifying qi and activating blood circulation";

Reduce the side effects of Western medicineFor example, some traditional Chinese medicines that nourish the body and strengthen the foundation can reduce the toxicity of certain chemotherapy drugs to the heart.

A novel therapeutic strategy using scopolamine to treat LPS induced myocardial injury

Septicemia induced myocardial dysfunction presents significant challenges in clinical management and is associated with increased mortality. Extracellular vesicles are small vesicles secreted by cells, carrying various bioactive molecules such as nucleic acids, proteins, and lipids. These vesicles can move to target cells to affect their function and regulate biological processes. Anisodamine (654-1/? 2) has the potential to alleviate heart and endothelial damage associated with sepsis. However, the mechanism by which scopolamine affects the communication between myocardium and endothelial cells, especially through extracellular vesicles, is still unclear. In this study, researchers demonstrated that scopolamine can alleviate myocardial cell dysfunction by repairing endothelial cell oxidative damage mediated by extracellular vesicles. This provides a new therapeutic approach for treating myocardial injury and highlights the potential of targeted extracellular vesicle therapy in clinical settings.

This study used the ImageXpress Micro confocal high content imaging analysis system from Molecular Devices to investigate the mitochondrial membrane potential and ROS production in A16 mouse myocardial cell models treated with LPS or scopolamineUsing JC-1 and ROS dyes for labeling, high mitochondrial membrane potential is displayed in red, while low mitochondrial membrane potential is displayed in green.

Activation and interaction of Nrf2/NRF1 signaling pathway enhance mitochondrial biosynthesis in the treatment of cardiac toxicity induced by Triptolide with genistein

Triptolide (TP) is a potential anti-tumor candidate drug, but it has multi organ toxicity, especially cardiac toxicity, which limits its clinical application. Mitochondrial dysfunction is a typical hallmark of triptolide induced cardiac toxicity. Previous studies have shown that flavonoids can enhance mitochondrial biogenesis to alleviate triptolide induced cardiac damage. The author's previous research has reported that flavones promote mitochondrial biosynthesis by activating nuclear respiratory factor 1 (NRF1), which has a protective effect on the cardiotoxicity of Triptolide. However, Nrf2 can also regulate mitochondrial biosynthesis, and its co regulatory role has not been fully elucidated. In this study, researchers demonstrated the role of Nrf2 in mitochondrial protection and demonstrated that NRF1 and Nrf2 enhance mitochondrial biogenesis and resist cardiotoxicity caused by Triptolide during the treatment process with genistein.

This study used the ImageXpress Micro 4 high-resolution imaging analysis system from Molecular Devices to investigate the actin dynamics of H9C2 myocardial cell models and the effects of flavonoid treatment on mitochondrial quality.Researchers labeled F: actin and G: actin with ghost pen cyclic peptide and deoxyribonuclease, captured images using the ImageXpress Micro 4 high content system, analyzed fluorescence intensity using MetaXpress software, and conducted imaging studies on mitochondrial mass (TOM20 expression) using ImageXpress Micro 4.

Large scale production of small extracellular vesicles loaded with Rg1 using a 3D bioreactor system to enhance the cardioprotective effect of doxorubicin induced cardiotoxicity

This study focuses on the low yield challenge faced by small extracellular vesicles (SEVs) in the treatment of doxorubicin induced cardiotoxicity (DIC), as well as the limited bioavailability of ginsenoside Rg1 despite its cardioprotective properties. Researchers utilized a three-dimensional (3D) bioreactor system to conduct large-scale expansion of human umbilical cord mesenchymal stem cells (MSCs). Compared to traditional two-dimensional culture methods, MSCs expanded to approximately 600 million within 5 days, and SEVs production reached 2.2 × 1012 particles, significantly increasing production and reducing operational costs. At the same time, using the electroporation method to load Rg1 into SEVs, the loading efficiency is about 21%, which is higher than methods such as ultrasound treatment or co incubation. Through experiments such as cell counting kit analysis and membrane associated protein V/PI staining, it has been confirmed that SEVs loaded with Rg1 can more effectively alleviate doxorubicin induced cardiomyocyte apoptosis compared to free Rg1 or ordinary SEVs, greatly enhancing the cardioprotective effect of DIC and opening up a promising new path for the clinical treatment of DIC.

This study used the ImageXpress Pico automated cell imaging system from Molecular Devices for live cell imaging and analysis.Inoculate H9c2 cells at a density of 8000 cells per well into a 96 well plate and perform continuous 24-hour fluorescence or bright field imaging using the ImageXpress Pico automated cell imaging system. Subsequently, the CellReporterXpress system was used to segment and count the cells. Researchers evaluated the cardioprotective effect of ginsenoside Rg1 in doxorubicin induced cardiac injury. Use gradient concentration of ginsenoside Rg1 to reduce doxorubicin induced apoptosis in H9c2 cells. Compared with the doxorubicin model group, treatment with 5 to 20 micrograms/milliliter of ginsenoside Rg1 increased the viability of H9c2 cells by about 10%.

The value of traditional Chinese medicine in the field of heart protection lies in its holistic and individualized approach, in preventing disease occurrence and improving clinical symptoms. It plays a unique advantage in improving the quality of life, promoting rehabilitation, and reducing the side effects of Western medicine. The high connotation imaging analysis system can provide assistance for the study of cardiac protection mechanisms and the screening of cardiac protective drugs, accelerating the progress of this field.
