Background and Objectives: With the growing incidence of acute myocardial infarction (MI), angiogenesis is vital for cardiac function post-MI. The role of bone marrow mesenchymal stem cells (BMSCs) in angiogenesis has been previously confirmed. Irisin is considered a potential vector for angiogenesis. The objective of the present study was to investigate the potential role of irisin in the angiogenesis of BMSCs. Methods: and Results: In vivo, irisin-treated BMSCs (BMSCs＋irisin) were transplanted into an MI mouse model. On day 28 post-MI, blood vessel markers were detected, and cardiac function and infarct areas of mice were evaluated. In vitro, paracrine effects were assessed by examining tube formation in human umbilical vein endothelial cells (HUVECs) co-cultured with the BMSCs＋irisin supernatant. The scratch wound-healing assay was performed to evaluate HUVEC migration. Western blotting was performed to determine PI3k/Akt pathway activation in the BMSCs＋irisin group. Transplantation of BMSCs＋irisin promoted greater angiogenesis, resulting in better cardiac function in the MI mouse model than in controls. In the BMSC＋irisin group, HUVECs demonstrated enhanced tube formation and migration. Activation of the PI3k/Akt pathway was found to be involved in mediating the role of irisin in the angiogenesis of BMSCs. Conclusions In cardiovascular diseases such as MI, irisin administration can enhance angiogenesis of BMSCs and pro-mote cardiac function via the PI3k/Akt pathway, optimizing the therapeutic effect based on BMSCs transplantation.

Objective To explore the risk factors and countermeasures of depression in stroke patients in Wuhan. Methods A stratified cluster sampling method was used to randomly select 628 hospitalized patients at acute stage of stroke in Wuhan from June 2019 to June 2020. According to HAMD score, the patients were divided into normal group (n=381) and post-stroke depression group (n=247). The risk factors of depression in stroke patients were analyzed by Logistic regression using self-made questionnaire, including gender, age, education level, stroke type, residence, patient compliance to treatment, NIHSS score, ADL score and independent walking, and early intervention measures were proposed. Results Univariate analysis showed that education level, family burden, NIHSS score, ADL score and independent walking were related to the occurrence of depression in stroke patients (P<0.05). Logistic multivariate regression analysis showed that, NIHSS score, ADL score and independent walking were correlated with depression in patients at acute stage after stroke (P<0.05). Conclusion the risk of depression in patients with acute cerebral apoplexy is higher, the patients' adherence to treatment, NIHSS score, ADL scores, situation of independent walking is a cause of depression in patients with cerebral apoplexy risk factors, should improve patients' adherence to treatment as soon as possible and daily life ability, improve nerve function, should pay attention to its early intervention.
