Neuroscience is a significant frontier discipline within the natural sciences and has become an important interdisciplinary frontier scientific field. Brain is one of the most complex organs in the human body, and its structural and functional analysis is considered the “ultimate frontier” of human self-awareness and exploration of nature. Driven by the strategic layout of “China Brain Project”, Chinese scientists have conducted systematic research focusing on “understanding the brain, simulating the brain, and protecting the brain”. They have made breakthrough progress in areas such as the principles of brain cognition, mechanisms and interventions for brain diseases, brain-like computation, and applications of brain-machine intelligence technology, aiming to enhance brain health through biomedical technology and improve the quality of human life. Due to limited understanding and comprehension of neuroscience, there are still many important unresolved issues in the field of neuroscience, resulting in a lack of effective measures to prevent and protect brain health. Therefore, in addition to actively developing new generation drugs, exploring non pharmacological treatment strategies with better health benefits and higher safety is particularly important. Epidemiological data shows that, exercise is not only an indispensable part of daily life but also an important non-pharmacological approach for protecting brain health and preventing neurodegenerative diseases, forming an emerging research field known as motor neuroscience. Basic research in motor neuroscience primarily focuses on analyzing the dynamic coding mechanisms of neural circuits involved in motor control, breakthroughs in motor neuroscience research depend on the construction of dynamic monitoring systems across temporal and spatial scales. Therefore, high spatiotemporal resolution detection of movement processes and movement-induced changes in brain structure and neural activity signals is an important technical foundation for conducting motor neuroscience research and has developed a set of tools based on traditional neuroscience methods combined with novel motor behavior decoding technologies, providing an innovative technical platform for motor neuroscience research. The protective effect of exercise in neurodegenerative diseases provides broad application prospects for its clinical translation. Applied research in motor neuroscience centers on deciphering the regulatory networks of neuroprotective molecules mediated by exercise. From the perspectives of exercise promoting neurogenesis and regeneration, enhancing synaptic plasticity, modulating neuronal functional activity, and remodeling the molecular homeostasis of the neuronal microenvironment, it aims to improve cognitive function and reduce the incidence of Parkinson’s disease and Alzheimer’s disease. This has also advanced research into the molecular regulatory networks mediating exercise-induced neuroprotection and facilitated the clinical application and promotion of exercise rehabilitation strategies. Multidimensional analysis of exercise-regulated neural plasticity is the theoretical basis for elucidating the brain-protective mechanisms mediated by exercise and developing intervention strategies for neurological diseases. Thus,real-time analysis of different neural signals during active exercise is needed to study the health effects of exercise throughout the entire life cycle and enhance lifelong sports awareness. Therefore, this article will systematically summarize the innovative technological developments in motor neuroscience research, review the mechanisms of neural plasticity that exercise utilizes to protect the brain, and explore the role of exercise in the prevention and treatment of major neurodegenerative diseases. This aims to provide new ideas for future theoretical innovations and clinical applications in the field of exercise-induced brain protection.

ObjectiveThe absorption of substances into blood is mainly dependent on the mesenteric lymphatic pathway and the portal venous pathway. The substances transported via the portal venous pathway can be metabolized by the biotransformation in the liver. On the contrary, the substances in the mesenteric lymph fluid enter the blood circulation without biotransformation and can affect the body directly. Alcohol consumption is strongly linked to global health risk. Previous reports have analyzed the changes of metabolites in plasma, serum, urine, liver and feces after alcohol consumption. Whether alcohol consumption affects the metabolites in lymph fluid is still unknown. Therefore, it is particularly important to explore the changes of substances transported via the mesenteric lymphatic pathway and analyze their harmfulness after alcohol drinking. MethodsIn this study, male Wistar rats were divided into high, medium, and low-dosage alcohol groups (receiving Chinese Baijiu at 56%, 28% and 5.6% ABV, respectively) and water groups. The experiment was conducted by alcohol gavage lasting 10 d, 10 ml·kg-1·d-1. Then mesenteric lymph fluid was collected for non-targeted metabolomic analysis by using liquid chromatography-mass spectrometry (LC-MS) and bioinformatic analysis. Principal component analysis and hierarchical clustering were performed by using Biodeep. Meanwhile, KEGG enrichment analysis of the differential metabolites was also performed by Biodeep. MetaboAnalyst was used to analyze the relationship between the differential metabolites and diseases. ResultsThe metabolites in the mesenteric lymph fluid of the high-dosage alcohol group change the most. Based on the KEGG enrichment analysis, the pathways of differential metabolites between the high-dosage alcohol group and the control group are mainly enriched in the central carbon metabolism in cancer, bile secretion, linoleic acid metabolism, biosynthesis of unsaturated fatty acids, etc. Interestingly, in the biosynthesis of unsaturated fatty acids category, the content of arachidonic acid is increased by 7.25 times, whereas the contents of palmitic acid, oleic acid, stearic acid, arachidic acid and erucic acid all decrease, indicating lipid substances in lymph fluid are absorbed selectively after alcohol intake. It’s worth noting that arachidonic acid is closely related to inflammatory response. Furthermore, the differential metabolites are mainly related with schizophrenia, Alzheimer’s disease and lung cancer. The differential metabolites between the medium-dosage alcohol and the control group were mainly enriched in phenylalanine metabolism, valine, leucine and isoleucine biosynthesis, linoleic acid metabolism and cholesterol metabolism. The differential metabolites are mainly related to schizophrenia, Alzheimer’s disease, lung cancer and Parkinson’s disease. As the dose of alcohol increases, the contents of some metabolites in lymph fluid increase, including cholesterol, L-leucine, fumaric acid and mannitol, and the number of metabolites related to schizophrenia also tends to increase, indicatingthat some metabolites absorbed by the intestine-lymphatic pathway are dose-dependent on alcohol intake. ConclusionAfter alcohol intake, the metabolites transported via the intestinal-lymphatic pathway are significantly changed, especially in the high-dosage group. Some metabolites absorbed via the intestinal-lymphatic pathway are dose-dependent on alcohol intake. Most importantly, alcohol intake may cause inflammatory response and the occurrence of neurological diseases, psychiatric diseases and cancer diseases. High-dosage drinking may aggravate or accelerate the occurrence of related diseases. These results provide new insights into the pathogenesis of alcohol-related diseases based on the intestinal-lymphatic pathway.

Acute respiratory distress syndrome (ARDS) is severe respiratory failure in clinical practice, with a mortality rate as high as 40%. Injury of pulmonary endothelial cells and alveolar epithelial cells occurs during ARDS, and pulmonary endothelial injury results in endothelial barrier disruption, which usually occurs before epithelial injury. Especially, when harmful factors enter the blood, such as sepsis and hemorrhagic shock, the pulmonary endothelial cells are affected firstly. The injured endothelial cells may loss cell-to-cell connections and even die. After the endothelial barrier is disrupted, fluid and proteins cross the endothelial barrier, causing interstitial edema. The alveolar epithelium is more resistant to injury, and when the tight barrier of the epithelium is broken, fluids, proteins, neutrophils, and red blood cells in the interstitium enter the alveolar space. From this process, it is easy to find that the endothelium is the first barrier to prevent edema, therefore, the protection of endothelium is the key to the prevention and treatment of ARDS. In addition, the injured endothelial cells express selectin and cell adhesion molecules, promoting the recruitment of immune cells, which exacerbate the inflammatory response and pulmonary endothelial cell injury. Mesenchymal stem cells (MSCs) can be derived from umbilical cord, bone marrow, adipose and so on. Because of low immunogenicity, MSCs can be used for allogeneic transplantation and have great application potential in tissue repairing. Through paracrine effect, MSCs can promote cell survival and balance inflammatory response. MSCs infused intravenously can locate in lungs rapidly and interact with endothelial cells directly, thus MSCs have advantages in protecting pulmonary microvascular endothelial cells. Animal experiments and clinical trials have found that MSC transplantation can significantly improve the symptoms of ARDS and reduce inflammatory reactions and endothelial permeability. Mechanically, MSCs acts mainly through paracrine and immunomodulatory effects. Paracrine cytokines from MSCs can not only promote pulmonary endothelial proliferation, but also reduce inflammatory response and promote cell survival to maintain endothelial integrity. In addition to paracrine cytokines, extracellular vesicles of MSCs are rich in RNAs, proteins and bioactive substances, which can protect pulmonary endothelial cells by intercellular communication and substance transport. Furthermore, MSCs may protect pulmonary endothelial cells indirectly by regulating immune cells, such as reducing the formation of extracellular trapping network of neutrophils, regulating macrophage polarization and regulating Th17/Treg cell balance. Although the beneficial effects of MSCs are verified, much work still needs to be done. MSCs from different tissues have their own characteristics and the scope of application. Different lung diseases possess different endothelial injury mechanisms. Thus, determining the indications of MSCs derived from different tissues is the direction of pulmonary disease clinical trials. From the perspective of transplantation route, intravenous injection of MSCs may have better clinical application in pulmonary endothelial injury caused by endogenous harmful factors in blood. Previous reviews mostly focused on the protective effects of MSCs on alveolar epithelium. In this article, we focused on endothelial cells and reviewed the direct protective effects and mechanisms of MSCs on endothelium through paracrine cytokines and extracellular vesicles, and summarize the mechanisms by which MSCs may indirectly protect pulmonary endothelial cells by regulating immune cells.
