Ischemic heart diseases are responsible for more than one-third of all deaths worldwide. Radix notoginseng is widely used to treat ischemic heart disease in China and other Asian countries, and notoginsenoside R1 (NGR1) is its characteristic and large-amount ingredient. However, the potential molecular mechanisms of NGR1 in improving ischemic heart diseases are unclear. In this study, we combined pharmacological evaluation with network pharmacology, myocardial proteomics, and conventional molecular dynamics (MD) simulation to explore the cardio-protection mechanisms of NGR1. Our results revealed that NGR1 improved the echocardiographic, tissue pathological, and serum biochemical perturbations in myocardial ischemic rats. The network pharmacology studies indicated that NGR1 mainly regulated smooth muscle cell proliferation, vasculature development, and lipid metabolism signaling, especially in the PI3K/AKT pathway. Myocardial proteomics revealed that the function of NGR1 was focused on regulating metabolic and energy supply processes. The research combined reverse-docked targets with differential proteins and demonstrated that NGR1 modulated lipid metabolism in ischemic myocardia by interacting with mTOR and AKT. Conventional MD simulation was applied to investigate the influence of NGR1 on the structural stabilization of the mTOR and AKT complex. The results suggested that NGR1 can strengthen the affinity stabilization of mTOR and AKT. Our study first revealed that NGR1 enhanced the affinity stabilization of mTOR and AKT, thus promoting the activation of the AKT/mTOR pathway and improving lipid metabolic abnormity in myocardial ischemic rats.

In recent years, the spread of the coronavirus disease 2019 (COVID-19) in China has been effectively controlled by implementing national prevention and control measures. However, a large number of recovered patients are plagued by fatigue, whether acute or chronic, and other fatigue-related syndromes that severely affect their quality of life. Post-viral fatigue syndrome (PVFS) is a widespread chronic neurological disease with no definite etiological factor(s), definitive diagnostic test, or approved pharmacological treatment, therapy, or cure. In this study, we performed a bibliometric analysis and the results suggested that neuroinflammation played a role in the development of PVFS. Therefore, we briefly analyzed the mechanisms underlying the development of neuroinflammation in patients with COVID-19. To identify effective drugs to alleviate PVSF, we summarized four traditional herbal phytoadaptations and discussed their molecular mechanisms in improving neurological fatigue. Our study showed that ginseng, Acanthopanax, Rhodiola, and Schisandra played beneficial roles in alleviating PVSF. Graphical abstract: http://links.lww.com/AHM/A45.

Strokes are a leading cause of morbidity and mortality in adults worldwide. Extensive preclinical studies have shown that neural-stem-cell-based treatments have great therapeutic potential for stroke. Several studies have confirmed that the effective components of traditional Chinese medicine can protect and maintain the survival, proliferation, and differentiation of endogenous neural stem cells through different targets and mechanisms. Therefore, the use of Chinese medicines to activate and promote endogenous nerve regeneration and repair is a potential treatment option for stroke patients. Here, we summarize the current knowledge regarding neural stem cell strategies for ischemic strokes and the potential effects of these Chinese medicines on neuronal regeneration.
