ObjectiveEndothelial cell dysfunction being the core link. This study explores the molecular mechanism of Danshen Tongluo formula in treating coronary artery disease-dominated panvascular disease with endothelial cell changes as the core through animal experiments and single-cell transcriptome sequencing. MethodsA rat model of coronary artery disease-dominated panvascular disease was established by ligating the left anterior coronary artery. Rats were randomized into a blank group, a model group, and a Danshen Tongluo formula (28 mg·kg-1·d-1) group. The efficacy was evaluated by examining the cardiac ultrasound, determination of the plasma level of N-terminal pro-brain natriuretic peptide, and pathological staining. After single-cell sequencing, SingleR package, public datasets, and related literature were used for annotation of the cells. Cell chat was used for intercellular communication and ligand-receptor analysis, and scmetabolism was used for metabolic analysis of endothelial cells. ResultsAnimal experiments showed that Danshen Tongluo formula reduced the N-terminal pro-brain natriuretic peptide ( NT-proBNP ) level (P<0.05), ameliorated myocardial cell damage and fibrosis, and increase left ventricular ejection fractions (LVEF) in the rat model of heart failure after myocardial infarction(P<0.05). Single-cell sequencing results showed that Danshen Tongluo formula increased the proportion of arterial endothelial cells, venous endothelial cells, and capillary-arterial endothelial cells, while reducing the proportion of capillary-venous endothelial cells. In addition, this formula increased the interaction intensity of endothelial cells with cardiomyocytes and M1 macrophages and reduced the interaction intensity of endothelial cells with fibroblasts and T cells. Danshen Tongluo formula upregulated CXCL12-CXCR4 signaling in endothelium-B cells and Ptprm-Ptprm signaling in endothelial endothelial cells, while downregulating Mif-(CD74+CXCR44) signaling in endothelium-M1 macrophages and Mif-(CD74+CD44) signaling in endothelium-M2 macrophages. It reduced the citric acid cycle, oxidative phosphorylation, and glycolysis and increased the glycolysis/oxidative phosphorylation ratio in endothelial cells. GO and KEGG enrichment analysis showed that arterial endothelial cells, venous endothelial cells, and venous capillary endothelial cells can all regulate oxidative phosphorylation, cell adhesion molecules, and tyrosine metabolism. Lymphatic endothelial cells regulate immunity and vascular constriction to participate in the metabolism of various amino acids and fatty acids. ConclusionDanshen Tongluo Formula can ameliorate coronary artery disease-dominated panvascular disease by changing the composition of endothelial cells and regulating the communication between myocardial endothelial cells and non-endothelial cells.

Coronary microvascular dysfunction (CMD) is one of the important causes of myocardial ischemia and non-obstructive coronary artery ischemic symptoms. However, effective diagnostic methods and targeted treatment strategies for CMD are currently lacking. According to traditional Chinese medicine (TCM), the comorbidity theory of "blood-vessel-cardiac collaterals" plays a central role throughout the entire development process of CMD. It suggests that in the clinical diagnosis and treatment of CMD, the treatment of blood, vessels, and cardiac collaterals should not be neglected. In light of this, insect medicines, known for their efficacy in promoting blood circulation, resolving stasis, and alleviating spasms, hold promise as a potential treatment for CMD. However, there is currently no research or summary on the use of insect medicines for the treatment of CMD. Therefore, this article took the comorbidity theory of "blood-vessel-cardiac collaterals" as the starting point and divided the pathogenesis of CMD into five evolution stages: Beginning in the blood (changes in blood components and hemorheology), progressing in the vessels (atheromatous plaque formation and unstable plaques), occurring in the cardiac collaterals (microvascular endothelial damage and microvascular constriction and spasms), ending in the cardiac collaterals (microvascular remodeling), and resulting in energy metabolism disorders throughout the process, so as to explore the pathogenesis and evolution of CMD. In addition, based on the modern pharmacological research on insect medicines, this article discussed the clinical application of insect medicines in the treatment of CMD from four aspects: Promoting blood circulation and removing blood stasis to relieve vessels' obstruction, relieving spasms to alleviate pain, combating poison with poison to disperse stagnation, and tonifying cardiac collaterals to nourish the heart, which aims to provide a theoretical basis for the use of TCM in treating CMD, broaden the scope of medication, and improve clinical efficacy.

BackgroundThe schizophrenia is majorly treated with drug and through physical therapy. However, both treatments would lead to adverse reactions, which could affect therapy adherence and treatment efficacy. Previous studies have shown that aerobic exercise can help alleviate cognitive function in patients with Alzheimer's disease and depressive disorder. At present, little research has been done on such alleviation in schizophrenia patients. ObjectiveTo explore the effect of aerobic exercise on cognitive function in male patients with chronic schizophrenia, so as to provide references for relevant treatments. MethodsA total of 76 male patients with chronic schizophrenia hospitalized in the Fourth People's Hospital of Wuhu between December 2022 and April 2023 were selected as the study subjects and, in accordance with random number table, divided into study group (n=36) and control group (n=40). Both groups received conventional drug treatment. On this basis, the study group received a 60-minute aerobic exercise 5 times a week for 8 weeks as intervention. Before and after intervention, assessment of cognitive function was performed by using MATRICS Consensus Cognitive Battery (MCCB) and Stroop Color Word Test (SCWT). ResultAfter intervention, compared with the control group, the study group spent less time on finishing the Trail Making Test and scored higher in both the spatial span test and maze test (Z=-2.070, -2.306, -2.375, P<0.05). Repeated measure ANOVA results showed that the time main effect of Hopkins Verbal Learning Test score was statistically significant in the two groups after intervention (F=39.067, P<0.05). So was the interaction effect between the time and group of the Brief Visuospatial Memory Test and Verbal Fluency Test scores (F=10.092, 9.252, P<0.05). After intervention, the scores of the Brief Visuospatial Memory Test and Verbal Fluency Test in the study group were higher than those in the control group (t=6.689, 4.249, P<0.05). As for the study group itself, the scores were higher than those before intervention (t=23.746, 23.842, P<0.05). After intervention, the numbers of correct reading in color test and word test in the study group were more than those in the control group (Z=-2.358, -2.771, P<0.05). The interaction effect between the time and group of the reaction time in color test, word test and color word interference test were statistically significant in both groups (F=23.383, 19.888, 19.662, P<0.05). After intervention, the reaction time in color test and color word interference test of the study group was shorter than those of the control group (t=4.895, 6.163, P<0.05). As for the study group itself, the reaction time were shorter than before intervention (t=54.318, 42.425, 42.141, P<0.01). ConclusionAerobic exercise may help alleviate the cognitive problems in male patients with chronic schizophrenia in terms of information processing speed, working memory, reasoning/problem solving ability, word learning and memorizing, visual learning and memorizing, and executive function.

In recent years, studies have shown that transplanted neural stem cells (NSCs) help neural tissues regenerate and return to normal through paracrine action rather than just replacing cells. Exosomes are essential paracrine mediators that can participate in cell communication through substance transmission. This review focuses on NSCs regulated by exosomes and their application in treatment of nervous system diseases, in order to provide important references for further research and clinical application of NSCs exosomes..
