Background: The antineoplastic activity of Chelidonium majus has been reported, but its mechanism of action (MoA) is unsuspected. The emerging theory of systems pharmacology may be a useful approach to analyze the complicated MoA of this multi-ingredient traditional Chinese medicine (TCM). Methods: We collected the ingredients and related compound-target interactions of C. majus from several databases. The bSDTNBI (balanced substructure-drug-target network-based inference) method was applied to predict each ingredienfs targets. Pathway enrichment analysis was subsequently conducted to illustrate the potential MoA, and prognostic genes were identified to predict the certain types of cancers that C. majus might be beneficial in treatment. Bioassays and literature survey were used to validate the in silico results? Results: Systems pharmacology analysis demonstrated that C. majus exerted experimental or putative interactions with 18 cancer-associated pathways, and might specifically act on 13 types of cancers. Chelidonine, sanguinarine, chelerythrine, berberine, and coptisine, which are the predominant components of C. majus, may suppress the cancer genes by regulating cell cycle, inducing cell apoptosis and inhibiting proliferation. Conclusions: The antineoplastic MoA of C. majus was investigated by systems pharmacology approach. C. majus exhibited promising pharmacological effect against cancer, and may consequently be useful material in further drug development. The alkaloids are the key components in C. majus that exhibit anticancer activity. 展开更多

The typical loess on high slopes along the BaoLan High-speed Rail, China, was selected as the research object. The influence of the freeze-thaw cycle and dry-wet alternation on the shear-strength parameters of the unsaturated loess was investigated by laboratory experimental methods. Moreover, the temperature field, seepage field, and stability of slopes with different gradients were simulated under the effect of the freeze-thaw cycle and dry-wet alternation by using the geotechnical analysis software Geo-Studio. The research results showed (1) when the freeze -thaw cycle was repeated on the slope, with the frozen depth increasing, the melted depth did the same;besides, the closed loop of isotherms formed on the slope;(2) under the action of dry-wet circulation, the negative pore-water pressure and volumetric water content showed an upward tendency. However, owing to the different slope gradients, rainfall infiltration was not the same. As time went by, the differences of the negative pore-water pressure and volumetric water content between the slopes of different gradients continued to increase;(3) with the freeze-thaw cycle and dry-wet alternation increasing, the slope-safety factor decreased. Especially in the early period, the slope-safety factor changed remarkably. For slopes undergoing freeze-thaw action, the slope-safety factor was negatively correlated with the gradient. However, with regard to slopes undergoing dry- wet alternation, the result became more complex because the slope-safety factor was related to both seepage strength and slope grade. Accordingly, further research is needed to study the effect of seepage strength and slope grade on the stability of loess slopes. 展开更多

Recognition of the human actions by computer vision has become an active research area in recent years. Due to the speed and the high similarity of the actions, the current algorithms cannot get high recognition rate. A new recognition method of the human action is proposed with the multi-scale directed depth motion maps(MsdDMMs) and Log-Gabor filters. According to the difference between the speed and time order of an action, MsdDMMs is proposed under the energy framework. Meanwhile, Log-Gabor is utilized to describe the texture details of MsdDMMs for the motion characteristics. It can easily satisfy both the texture characterization and the visual features of human eye. Furthermore, the collaborative representation is employed as action recognition by the classification. Experimental results show that the proposed algorithm, which is applied in the MSRAction3 D dataset and MSRGesture3 D dataset, can achieve the accuracy of 95.79% and 96.43% respectively. It also has higher accuracy than the existing algorithms, such as super normal vector(SNV), hierarchical recurrent neural network(Hierarchical RNN). 展开更多

'犯罪是行为'中的'行为'、构成要件要素中的'行为'(具体包括阶层犯罪论体系构成要件符合性中的'行为'要素、平面四要件体系犯罪客观方面中的'行为'要素)、行为无价值中的'行为'等,属于既有联系又有区别的概念群。考察我国的刑法规范,'行为'应当分为广义(人造成的外界状态的改变)、中义、狭义、最狭义。尤其是在采取控制行为论时,将狭义的'行为'界定为'主体控制或应该控制的客观条件作用于一定的人或物的存在状态的过程'之后,这一考镜源流的工作具有多重意义,首先,有利于明晰'行为'概念与相关概念——尤其是'结果'概念的关系,避免学术上的无谓争论;其次,有利于树立建构犯罪论体系的方法论,准确认定犯罪行为的性质;最后,有利于撩开犯罪论诸疑难问题的神秘面纱,推进犯罪论知识的更新。 展开更多

Natural active molecules are key sources of modern innovative drugs. Particularly, a great amount of natural active molecules have been reported to possess promising therapeutic effects on inflammatory diseases, including asthma, rheumatoid arthritis, hepatitis, enteritis, metabolic disorders and neurodegenerative diseases. However, these natural active molecules with various molecular structures usually exert anti-inflammatory effects through diversiform pharmacological mechanisms, which is necessary to be summarized systematically. In this review, we introduced the current major anti-inflammatory natural active molecules based on their chemical structures, and discussed their pharmacological mechanisms including anti-inflammatory molecular signaling pathways and potential target proteins, which providing a referential significance on the development of novel anti-inflammatory drugs, and also revealing new therapeutic strategies for inflammatory diseases. 展开更多
