Soybean is widely used in diets,and numerous reports have highlighted its antioxidant properties.However,constructing a methodology for rapid identifying and predicting a series of antioxidant active ingredients in Soybean presents certain challenges.Therefore,we introduced the spectrum-effect relationship-ingredient knockout identification technique to identify a series of antioxidant active ingredients in soybean.By combining untargeted metabolomics with network pharmacology,we predicted the antioxidant active ingredients and their target sites.We successfully identified 4 antioxidant active compounds(daidzein,genistein,daidzein,and glycitin)and 10 corresponding antioxidant targets(epidermal growth factor receptor(EGFR),estrogen receptor 1(ESR1),steroid receptor coactivator(SRC),tumor necrosis factor(TNF),kinase insert domain receptor(KDR),AKT serine/threonine kinase 1(AKT1),growth factor receptor bound protein 2(GRB2),signal transducer and activator of transcription1(STAT1),mitogen-activated protein kinase 8(MAPK8),B-cell lymphoma-2(BCL2))by our analysis.The validation results from cell experiments revealed that glycitin exhibited the best antioxidant activity and significantly influenced the expression of EGFR and the proteins associated with nuclear factor erythroid 2-related factor 2/NAD(P)H quinone dehydrogenase 1(NRF2/NQO1)signaling pathways.These findings were consistent with the predicted outcomes and were further confirmed in a zebrafish model.It suggests that glycitin may exert antioxidant effects by regulating the expression of EGFR,NRF2,and NQO1 proteins.The results demonstrate that a rapid analytical method for determining antioxidant activity was established. 展开更多

Since the chromatographic fingerprint was introduced, it has been accepted by many countries to assess the quality and authenticity of Chinese herbal medicine (CHM). However, solely using the chromatographic fingerprint to assay numerous chemicals is not suitable for the assessment of the whole internal quality and pharmacodynamics of CHM. Consequently, it is necessary to develop a rational approach to connecting the chromatographic fingerprint with effective components to assess the internal quality of CHM. For this purpose, a spec^tun-effect relationship theory was proposed and accepted as a new method for the assessment of CHM because of its potential use to screen effective components from CHM. In this paper, we systematically reviewed the application of the spectrum-effect relationship theory in the research of CHM, including research mentality, different chromatographic analysis techniques, data processing technologies, and structure determination. 展开更多

The traditional Chinese medicine of Radix Hedysari plays an important role in invigorating gas for ascending, benefiting blood for promoting production of fluid, and promoting circulation for removing obstruction in collaterals, which is consistent with the principle of treatment for osteoporosis. This study is designed to investigate the bioactive components on increasing peak bone mass (PBM) by exploring the spectrum-effect relationship between chromatography fingerprints and effect. Multiple indicators are selected to evaluate the pharmacological activity. In fingerprints, 21 common peaks are obtained, five of which are identified. Furthermore, gray relational analysis (GRA) is a quantitative method of gray system theory and is used to describe the correlation degree of common peaks and pharmacological activities with relational value. 21 components are then divided into three different regions, of which ononin and calycosin play an extremely significant role in increasing PBM. In addition, factor analysis and hierarchical cluster analysis (HCA) are used to screen the optimal producing area for Radix Hedysari. This provides a comprehensive and efficient method to improve the quality evaluation of Radix Hedysari, confirming the bioactive components for PBM-enhancement and further develop its medicinal value. 展开更多

Quality control and screening of active substances in traditional Chinese medicines have been performed using fingerprint analysis.The spectrum-effect relationship between chromatography fingerprints and efficacy of herbal drugs is considered as a potentially useful method for determining active ingredients in complex mixtures.The study was designed to develop a method for determining the bioactive components of a compound Chinese medicine called Tiefeng based on spectrum-effect relationships between high-performance liquid chromatography(HPLC)fingerprints and anticoccidial activities.Four peaks of the established HPLC fingerprint indicate the main bioactive components of this medicine.In addition,pharrnacodynamic atlas was defined and used to assess the anticoccidial activity of Tiefeng from different sources for the first time.We found that the level of anticoccidial activity of Tiefeng was consistent with the degree of similarity between the pharmacodynamic atlas and chromatogram of any sample.Furthermore,effect of this medicine was related with the main active constituents,along with the origin and the harvesting time. 展开更多

Objective: This study aimed to identify the main medicinal active components of Panax ginseng(P. ginseng) in the compatibility environment of clinical application. For this purpose, the anti-inflammatory ingredients of P. ginseng were investigated based on its therapeutic effect in Sijunzi Decoction(SJD) which is a widely used traditional Chinese formula.Methods: The fingerprints of 10 batches of SJD consisting of different sources of P. ginseng were established by UPLC technique to investigate the chemical components. At the same time, the antiinflammatory effects of these components were evaluated by dextran sulfate sodium-induced ulcerative colitis mouse model. Grey relational analysis was applied to explore the correlation degree between fingerprints and anti-inflammatory effects in SJD. Lipopolysaccharide-stimulated RAW264.7 murine macrophages were established to evaluate the anti-inflammatory action of the screened effective substances of P. ginseng.Results: According to grey relational analysis, notoginsenoside R1, ginsenoside Rg2 and ginsenoside Rb3of P. ginseng were the major anti-inflammatory contributions in SJD. They had been proven to be closely associated with the anti-inflammatory process of SJD and displayed a close effect compared with SJD by LPS-stimulated RAW264.7 murine macrophages.Conclusion: Our work provides a general strategy for exploring the pharmacological ingredients of P. ginseng in traditional Chinese formulas which is beneficial for establishing the quality standards of traditional herbs in traditional Chinese medicine prescription based on their clinical therapeutic effect. 展开更多

Lonicerae Japonicae Flos is a significant food and traditional Chinese medicine,known as plant antibiotics.It has rich chemical constituents and significant pharmacological effects.The antitumor activity of Lonicerae Japonicae Flos has been clarified,but the study on its spectrum-effect relationship has not been reported.The compounds responsible for its antitumor activity are still unknown.In this study,processed products of Lonicerae Japonicae Flos at different temperatures were taken as experimental materials,and SMMC-7721,A549,andMGC80-3 cells were tested.The orthogonal partial least squares regressionmethod was used to analyze the common compounds in different processed products and the antitumor activity.The results show that processed products have a stronger inhibitory effect on A549 cells and MGC80-3 cells than SMMC-7721 cells.Compounds such as secologanic acid,isochlorogenic acid A,serotonin,and chlorogenic acid play an important role in their antitumor effects. 展开更多

现代化战争中,群智通信对抗已成为认知电子战的重要发展趋势。现有认知干扰手段主要聚焦于单目标对抗场景,随着敌方目标设备抗干扰能力的提升和规模的扩大,难以达到理想的干扰效果。然而多干扰机在协同过程中内部关系耦合复杂且往往存... 现代化战争中,群智通信对抗已成为认知电子战的重要发展趋势。现有认知干扰手段主要聚焦于单目标对抗场景,随着敌方目标设备抗干扰能力的提升和规模的扩大,难以达到理想的干扰效果。然而多干扰机在协同过程中内部关系耦合复杂且往往存在决策冲突,导致干扰频谱资源浪费、协作效率低下,无法满足干扰的时效性需求。针对此问题,提出群智通信对抗环境下的认知干扰频谱资源博弈决策架构及方法,在博弈论和机器学习理论方法的指导下,围绕协同干扰博弈决策模型与效果评估机理、面向瞬时均衡收益的干扰高效决策压制以及面向长期累积收益的干扰稳健决策占优等多个方面,对关键技术展开论述,通过构建“内部协同、外部对抗”博弈模型与间接效果评估机制,缓解反馈缺失问题,并结合合作式多智能体学习提升联合决策能力。新方法在压制能力、协同效率和策略稳定性上均优于现有方法。 展开更多

在高维数据聚类中,数据噪声对算法性能影响显著,因此降维处理十分必要.谱聚类在复杂数据结构上表现良好,其正则化形式虽能提升平滑性与拟合效果,但仍存在局限.传统方法常对图拉普拉斯矩阵的特征向量采用K均值等算法聚类,其特征向量的聚... 在高维数据聚类中,数据噪声对算法性能影响显著,因此降维处理十分必要.谱聚类在复杂数据结构上表现良好,其正则化形式虽能提升平滑性与拟合效果,但仍存在局限.传统方法常对图拉普拉斯矩阵的特征向量采用K均值等算法聚类,其特征向量的聚类质量直接影响最终结果,故需选择更为可靠的特征向量聚类方法.针对以上问题,文章提出了基于贝叶斯标签传播的正则化谱聚类算法(BLP-RSC),使用UMAP方法对原始高维数据进行降维,以减少噪声与冗余信息的影响,采用正则化谱聚类对降维后数据进行谱分解,得到对应的特征向量,基于贝叶斯相关理论构建可靠样本选择机制,筛选出高置信度的样本点作为初始标签集,最后通过标签传播算法对特征向量进行聚类,并在5个UCI真实数据集上验证了该方法的有效性. 展开更多
