Shuxuening Injection Inhibits Apoptosis and Reduces Myocardial Ischemia-Reperfusion Injury in Rats through PI3K/AKT Pathway

Chinese Journal of Integrative Medicine 2024年第5期30卷 421-432页

作者： YUE Tong-tong CAO Ying-jie CAO Ya-xuan LI Wei-xia WANG Xiao-yan SI Chun-ying XIA Han zhu Ming-jun TANG Jin-fa.WANG He The First Clinical Medical College of Henan University of Chinese Medicine Zhengzhou 450046China Department of Pharmacy the First Affiliated Hospital of Henan University of Chinese MedicineZhengzhou 451200China Department of Cardiovascular Diseases the First Affiliated Hospital of Henan University of Chinese MedicineZhengzhou 451200China

Objective: To investigate the main components and potential mechanism of Shuxuening Injection(SXNI) in the treatment of myocardial ischemia-reperfusion injury(MIRI) through network pharmacology and in vivo research. Methods: The Traditional Chinese Medicine Systems Pharmacology(TCMSP) and Pharm Mapper databases were used to extract and evaluate the effective components of Ginkgo biloba leaves, the main component of SXNI. The Online Mendelian Inheritance in Man(OMIM) and Gene Cards databases were searched for disease targets and obtain the drug target and disease target intersections. The active ingredient-target network was built using Cytoscape 3.9.1 software. The STRING database, Metascape online platform, and R language were used to obtain the key targets and signaling pathways of the anti-MIRI effects of SXNI. In order to verify the therapeutic effect of different concentrations of SXNI on MIRI in rats, 60 rats were first divided into 5 groups according to random number table method: the sham operation group, the model group, SXNI low-dose(3.68 mg/kg), medium-dose(7.35 mg/kg), and high-dose(14.7 mg/kg) groups, with 12 rats in each group. Then, another 60 rats were randomly divided into 5 groups: the sham operation group, the model group, SXNI group(14.7 mg/kg), SXNI+LY294002 group,and LY294002 group, with 12 rats in each group. The drug was then administered intraperitoneally at body weight for 14 days. The main biological processes were validated using in vivo testing. Evans blue/triphenyltetrazolium chloride(TTC) double staining, hematoxylin-eosin(HE) staining, terminal deoxynucleotidyl transferase d UTP nick end labeling(TUNEL) assay, enzyme-linked immunosorbent assay(ELISA), and Western blot analysis were used to investigate the efficacy and mechanism of SXNI in MIRI rats. Results: Eleven core targets and 30 Kyoto Encyclopedia of Genes and Genomes(KEGG) pathways were selected. Among these, the phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT) pathway was

Continuous gradient fusion class activation mapping: segmentation of laser-induced damage on large-aperture optics in dark-field images

引用

High Power Laser Science and Engineering 2024年第1期12卷 30-41页

作者： Yueyue Han Yingyan Huang Hangcheng Dong Fengdong Chen fa.Zeng Zhitao Peng Qihua zhu Guodong Liu School of Instrumentation Science and Engineering Harbin Institute of TechnologyHarbinChina Research Center of Laser Fusion China Academy of Engineering PhysicsMianyangChina

Segmenting dark-field images of laser-induced damage on large-aperture optics in high-power laser fa.ilities is challenged by complicated damage morphology, uneven illumination and stray light interference. Fully supervised semantic segmentation algorithms have achieved state-of-the-art performance but rely on a large number of pixel-level labels, which are time-consuming and labor-consuming to produce. LayerCAM, an advanced weakly supervised semantic segmentation algorithm, can generate pixel-accurate results using only image-level labels, but its scattered and partially underactivated class activation regions degrade segmentation performance. In this paper, we propose a weakly supervised semantic segmentation method, continuous gradient class activation mapping(CAM) and its nonlinear multiscale fusion(continuous gradient fusion CAM). The method redesigns backpropagating gradients and nonlinearly activates multiscale fused heatmaps to generate more fine-grained class activation maps with an appropriate activation degree for different damage site sizes. Experiments on our dataset show that the proposed method can achieve segmentation performance comparable to that of fully supervised algorithms.

针对评价信息为概率语言术语且属性权重未知的多属性群决策问题,提出一种新的、基于离平均解距离(EDAS)和共识模型的概率语言多属性后悔理论群决策方法.首先,考虑到现实决策中决策者面对方案选择时会呈现“有限理性”的行为,将后悔理论融入群决策方法的研究中,通过计算决策者的后悔-欣喜值来度量其感知效用;其次,将EDAS方法与概率语言信息处理相结合用于方案排序,并基于最大化偏差法思想,给出一种概率语言多属性决策问题属性权重的确定方法,以得到初始解决方案;然后,对初始解决方案进行共识测度,进一步根据个人属性集得到个人方案集,通过共识模型的动态反馈调整,得到符合大多数决策者意愿的最终解决方案;最后,以共享自行车设计方案的选择为例对所提出方法进行验证,并通过对比分析说明方法的可行性和有效性.
