Ziziphi Spinosae Semen (ZS, the seeds of Ziziphus jujuba Mill. var. spinosa (Bunge) Hu ex H. F. Chou) is used as a traditional Chinese medicine referred to as Suan zao ren (酸枣仁). This paper aims to provide a systematic review of its traditional uses and its botanical, phytochemical, pharmacological, pharmacokinetic, and toxicological characteristics. The future development and research prospects for ZS have also been discussed in detail. To date, over 150 compounds have been identified in this plant, including terpenoids, alkaloids, flavonoids, fatty acids, volatile oils, polysaccharides, and others. Both extracts and purified compounds have excellent biological activities, especially sedative and hypnotic effects. Other effects include ameliorating effect of learning and memory, anti-inflammation, antioxidation, blood pressure and lipid lowering, antiaging, and antitumor effects. Thus, this traditional Chinese medicine can be used to treat many diseases such as insomnia, forgetfulness, headaches, and dizziness. Although many of the traditional uses of ZS are well established, the relationship between structure and function still needs to be further studied. In order to better pave the way for research and the establishment of quality control standards for ZS, it will be very important to elucidate its pharmacological mechanisms of action and explore new clinical effects.

Corydalis yanhusuo W. T. Wang (Papaveraceae) is a traditional Chinese herbal medicine that has long been used to treat several conditions and is widely distributed in Asian countries. This review focuses on the traditional uses, botany, phytochemistry, pharmacology, pharmacokinetics, and toxicology of C. yanhusuo. The literature on C. yanhusuo was reviewed using several resources, including classic books on Chinese herbal medicine and scientific databases, namely, PubMed, Springer, Web of Science, Science Direct, and China National Knowledge Infrastructure. Based on information from these databases regarding the chemical components of C. yanhusuo, we evaluated the underlying interaction network between chemical components, biological targets, and associated diseases using Cytoscape software. To date, more than 160 compounds have been isolated and identified from C. yanhusuo, including alkaloids, organic acids, volatile oils, amino acids, nucleosides, alcohols, and sugars. The crude extracts and purified compounds of this plant have analgesic, antiarrhythmic, and antipeptic ulcer properties, along with hypnotic effects. However, studies on the pharmacokinetics of C. yanhusuo extracts remain limited. C. yanhusuo has therapeutic potential in diseases such as cancer and depression, probably due to glaucine and corydaline. Our network pharmacology analysis revealed interactions between 20 compounds, 54 corresponding targets, and 4 health conditions. We found that leonticine, tetrahydroberberine, and corydalmine may regulate the expression of PTGS2, PTGS1, KCNH2, SCN5A, RXRA, CAMKK2, NCOA2, and ESR1, representing a potential treatment strategy against pain, gastric ulcers, inflammation, and cardiac arrhythmias. Additionally, this article discusses the future directions of research on C. yanhusuo.

Aim of the Study. This paper summarizes the traditional uses, botany, chemical composition, pharmacology, pharmacodynamics, and toxicology of Arisaematis rhizoma (hereafter referred to as AR). In addition, the future development and research prospect of AR were discussed in detail. Although many traditional uses of AR have been confirmed, it is essential to study the relationship between its structure and function, clarify the mechanism of pharmacological action, and explore new clinical applications. Materials and Methods. This review is a collection of all possible studies on AR, published in scientific journals, papers, and books. Using the papers related to Arisaematis, such as ScienceDirect, Wiley Online Library, Springer Link, Web of Science, CNKI, and WanFang Database. In this paper, the traditional uses, botany, phytochemistry, pharmacology, and toxicology of AR were reviewed. Finally, the existing problems and research directions of the research on AR are discussed. Results. Ninety-eight chemical constituents were isolated from AR. AR has a wide range of pharmacological effects, such as the effects on the central nervous system and cardiovascular system. It also has anti-tumor, sedative, analgesic, anticonvulsant, anti-inflammatory, expectorant, antiarrhythmic, anticoagulant, and other effects. It is also considered an effective drug for in vitro and in vivo validation. Conclusions. AR is an excellent traditional medicinal plant in China. Pharmacological studies support the traditional use of AR and may verify the folk use of AR in the treatment of different diseases. The anti-tumor effect of AR has been widely concerned by scholars at home and abroad. It has become a hot spot in recent years and has made great contributions to the survival and development of human beings. Although it has a high value of comprehensive utilization, its development and utilization are far from enough. Therefore, the comprehensive development of AR is worthy of further analysis.

Low-carbon agriculture is essential for protecting the global climate and sustainable agricultural economics. Since China is a predominantly agricultural country, the adoption of low-carbon agricultural technologies by local farmers is crucial. The past literature on low-carbon technologies has highlighted the influence of demographic, economic, and environmental factors, while the psychological factors have been underexplored. A questionnaire-based approach was used to assess the psychological process underlying the adoption of low-carbon agricultural technologies by 1,114 Chinese rice farmers in this paper, and structural equation modeling (SEM) was empirically employed to test our theoretical model. The results indicated that farmers’ low-carbon production attitude and behavioral efficiency perception directly and positively affected the adoption of low-carbon agricultural technologies and indirectly affected it via low-carbon production intention. Besides, production implementation cost and socio-environmental factor could moderate the direct effects of low-carbon production attitude, behavioral efficiency perception, and low-carbon production intention on farmers’ adoption of low-carbon agricultural technologies. In this respect, socio-environmental factor yielded more significant moderating effects. Additionally, this research provides policy implications for promoting low-carbon agricultural technologies in developing countries and regions.

Taxifolin (TXL), also known as dihydroquercetin, is one of the most important flavonoids prevalent across the plant kingdom. Increasing evidence has demonstrated its critical role in respiratory diseases. The present study aims to reveal the detailed mechanism in TNF-α-stimulated BEAS-2B cells by which TXL might exert effects on the development of asthma. Cell viability detection of BEAS-2B treated with TXL before and after TNF-α induction employed MMT. The expressions of inflammatory cytokines, MUC5AC and ICAM-1 were determined by quantitative reverse transcription PCR (RT-qPCR), enzyme-linked immunosorbent assay (ELISA) and Western blot after TXL was exposed to an in vitro asthma model. Then, light transmittance and apoptosis were then measured employing fluorescein transmittance, TUNEL and Western blot. After overexpressing MMP10, the abovementioned assays were performed again. Finally, the association between Wnt/β-catenin pathway and MMP10 was confirmed by detecting the proteins in this pathway. TXL increases the cell viability of TNF-induced BEAS-2B cells. TXL suppressed the inflammation, mucus formation, and apoptosis in TNF-α-induced BEAS-2B cells. Furthermore, after the prediction of binding sites between TXL and MMP10, it was found that overexpression of MMP10 reversed the effects of TXL on suppressing the progression of TNF-α-induced BEAS-2B cells. Finally, TXL blocked Wnt/β-catenin pathway by inhibiting MMP10 expression. TXL can be a promising drug for the treatment of asthma due to its inhibition of MMP10 expression by blocking Wnt/β-catenin pathway. Future experimental in vivo studies of asthma on this commonly used bioactive flavonoid could open new avenues for the therapies of asthma.
