目的:应用元分析的方法探讨中国学生学校归属感与学业成绩之间的关系,并探究影响二者关系的调节因素。方法:通过文献检索,共有32篇文献、38个独立样本纳入标准(n=31121)。异质性检验表明,选择随机效应模型比较合适。结果:漏斗图和Egger's检验结果显示,本元分析不存在发表偏差;主效应检验发现,学校归属感与学业成绩呈中等程度的显著正相关(r=0.21,P<0.001,95%CI为[0.15,0.27]);调节效应检验发现,二者关系受生源地类型的调节,但不受性别、学校归属感测量工具和学生群体类别的影响。结论:中国学生的学校归属感与学业成绩之间的关系密切;同时还要考虑生源地类型在二者关系中的调节效应,未来研究可进一步聚焦于农村学生这一群体。

Atorvastatin Alleviates Myocardial Ischemia-Reperfusion Injury via miR-26a-5p/FOXO1

引用

Journal of Biosciences and Medicines 2023年第2期11卷 215-231页

作者： Jinlan Duan Tong Zhang Ying zhu bingtuan Lu Qi Zheng Ninghui Mu Department of Geriatric Practice The First People’s Hospital of Yunnan Province The Affiliated Hospital of Kunming University of Science and Technology Kunming China Department of General Practice The First People’s Hospital of Yunnan Province The Affiliated Hospital of Kunming University of Science and Technology Kunming China

Purpose: Ischemia-reperfusion (I/R) injury exacerbates myocardial cell death (including apoptosis and necrosis), leading to complications such as arrhythmias, myocardial stenosis, microvascular obstruction and heart failure, and it is particularly important to seek new strategies to mitigate reperfusion injury. In this paper, we will investigate whether atorvastatin can alleviate myocardial ischemia-reperfusion injury and verify its molecular mechanism. Methods: We successfully constructed a hypoxia-reperfusion (H/R) H9c2 cell model and transfected miR-26a-5p mimic, miR-26a-5p inhibitor and its negative control NC-mimic or NC-inhibitor into H9c2 cells using a transfection kit. The expression of miR-26a-5p and FOXO1 were detected by RT-qPCR assay, the expression of related proteins by Western blot assay, the cell viability of H9c2 cells by CCK-8 assay, the apoptosis rate of H9c2 cells by flow cytometry, the CK and LDH activity in cells by CK and LDH assay kits. The targeting relationship between miR-26a-5p and FOXO1 was verified by dual luciferase reporter gene assay. Results: MiR-26a-5p expression was decreased in H/R-induced cells and FOXO1 expression was increased in H/R-induced cells. Atorvastatin alleviated H/R injury in cardiomyocytes and was most effective at a concentration of 1 μM. Atorvastatin alleviated H/R injury in cardiomyocytes by upregulating miR-26a-5p expression, miR-26a-5p and FOXO1 were negatively regulated by targeting. Conclusion: Atorvastatin can alleviate H/R injury in cardiomyocytes by regulating miR-26a-5p/FOXO1.
