Qufeng Zhitong capsule (QZC), a Chinese patent medicine officially approved in China for the treatment of rheumatoid arthritis (RA) and other diseases, possesses the primary effects of dispelling wind, relieving pain, and promoting blood circulation, whose clinical applications have been confined owing to the incomplete elucidation of its chemical compositions and the underlying molecular mechanism for the treatment of RA. In this study, 61 compounds including 16 phenylpropanoids, 15 organic acids, 13 alkaloids, seven flavonoids, six iridoids, one saccharide, two aldehydes, and one saponin in QZC were simultaneously identified and traced to their herbal origins by ultra-high performance liquid chromatography tandem Q-Exactive Orbitrap high-resolution mass spectrometry (UHPLC/Q-Orbitrap-MS), where 31 of them were unambiguously identified by reference compounds, and the other 30 were tentatively characterized. Besides, all these compounds were proven to have potential pharmacological activity in the treatment of RA based on network pharmacology analysis. In conclusion, this study first investigated the chemical composition and potential pharmacological effects of the main chemical compounds in QZC, which will contribute to the revelation of bioactive compounds in QZC and provide evidence for clinical application.

As the representatives of closely related Chinese medicinal materials (CMMs) originated from Rutaceae family, Aurantii fructus immaturus (AFI), Aurantii fructus (AF), Citri reticulatae pericarpium viride (CRPV), and Citri reticulatae pericarpium (CRP) have better functions in regulating qi and promoting gastrointestinal motility. However, differences in the quality of closely related Citrus CMMs have not yet been revealed until now. Herein, this study focused on the systematic differentiation and in-depth understanding of closely related Citrus CMMs by a strategy integrating chemometrics and network pharmacology. Determined by ultra performance liquid chromatography, the content of nine flavonoids showed obvious fluctuations in the decoction pieces from different species (Citrus aurantium Linnaeus and Citrus reticulate Blanco) with decreasing levels in the samples of ripe fruits. Decoction pieces from the different species and ripening stages were well distinguished by orthogonal projection to latent structure-discriminate analysis (OPLS-DA) and cluster analysis. As a result, four active components including narirutin, naringenin, hesperidin, and 3,5,6,7,8,3′,4′-heptemthoxyflavone were filtered out by variable importance for the projection (VIP) value (VIP > 1.0), which were regarded as chemotaxonomic markers. Furthermore, a components-targets-diseases network was constructed via ingenuity pathway analysis (IPA), and the correlations were predicted between four chemotaxonomic markers, 223 targets, and three diseases including colitis, breast cancer, and colorectal cancer. The obtained results will be of great significance for identifying closely related Citrus CMMs and conduce to improving the resource utilization of CMMs.

This research studies applied feminism theories to evaluate animal protection law and its related implementation, practical measures, and insufficient measures with a comparative approach. Elizabeth Cady Stanton's liberal Feminism was employed to investigate the current dilemmas of animal protection law. The goal is to identify and discover the best practice internationally to guide the ongoing animal protection law legislation in China, a principal legal lacuna of the Chinese civil law system with a holistic perspective of feminism theories. Betty Friedan changed philosophical and ideological attitudes toward sex and raised the ethical argument of animal rights. This study found that the differences between social conditions, legislation reasons, social economics, cultures, conventions must be considered. At the same time, the human emotions, the animal's human relationship, the male-controlled capitalist hierarchy, the relationship between animal and female rights are universal. A historical context perspective was employed in all analyses between animal protection and Feminism in history. The roots of the current animal protection issues were found and studied. A number of solutions on the current animal protection were suggested based on feminism theories. "Equality of opportunity" is the primary instrument for designing solutions. Harming animals is also related to patriarchy. "We hold these truths to be self-evident; that all men and women are created equal." Therefore, if we want to make a breakthrough in animal protection law, we must be able to implement measures in many aspects at the same time to maximize the effect.
