    Abstract Background. Liver injury has been recognized as a primary cause of hepatic morbidity and mortality. Euscaphis konishii Hayata, also called Euscaphis fukienensis Hsu, is usually used as a detumescent and analgesic agent to improve liver function in South China, but its mechanism of action and chemical composition are unclear. Objective. The main aim of the study was to investigate the constituent and potential hepatoprotective mechanism of the total triterpenes of E. konishii pericarp (TTEP). Methods. The constituent of TTEP was analyzed by a series of silica gel column to get single compounds and then identified by NMR and MS. In vitro assays were conducted to test the free radical scavenging activity of TTEP. The BCG/LPS-induced immunological livery injury mice model was established to clarify the hepatoprotective effect of TTEP in vivo. Results. 8 pentacyclic triterpene acids were separated and identified by NMR and MS. TTEP treatment (50, 100, and 200 mg/Kg) improved the immune function of the BCG/LPS-infected mice, dose-dependently alleviated the BCG/LPS-induced inflammation and oxidative stress, and ameliorated the hepatocyte apoptosis in the liver tissue. Conclusion. The pericarp of E. konishii may be further considered as a potent natural food for liver disease treatment.

    Abstract The relative roles of geography, climate and ecology in driving population divergence and (incipient) speciation has so far been largely neglected in studies addressing the evolution of East Asia’s island flora. Here, we employed chloroplast and ribosomal DNA sequences and restriction site-associated DNA sequencing (RADseq) loci to investigate the phylogeography and drivers of population divergence of Neolitsea sericea. These data sets support the subdivision of N. sericea populations into the Southern and Northern lineages across the ‘Tokara gap’. Two distinct sublineages were further identified for the Northern lineage of N. sericea from the RADseq data. RADseq was also used along with approximate Bayesian computation to show that the current distribution and differentiation of N. sericea populations resulted from a combination of relatively ancient migration and successive vicariant events that likely occurred during the mid to late Pleistocene. Landscape genomic analyses showed that, apart from geographic barriers, barrier, potentially local adaptation to different climatic conditions appears to be one of the major drivers for lineage diversification of N. sericea.

    Abstract The objective was to study the present scenario, challenges, and future anticipation of traditional Mongolian medicine (TMM) in China. The literature was retrieved using various sources of information such as meetings with TMM experts, research and review articles, national health databases, and government websites and authoritative papers. Health care using TMM, TMM education and research, and the pharmaceutical industry of TMM has been improved by implementing TMM growth policies. TMM has been extensively used for health care in Mongolia and in various regions of China including Beijing. The national education system of China contains a stream of TMM education. There is a yearly increase in research productivity in the field of TMM due to extensive research funding by the government. The rapidly growing pharmaceutical industry of TMM has provided more availability of TMM to more patients. The literature search revealed good preservation and development of TMM in China, urging the need to take steps for the promotion of its spread and development in China and worldwide.

    Abstract Activation of the histamine‐3 receptor (H3R) is involved in memory processes and cognitive action, while blocking H3R activation can slow the progression of neurological disorders, such as Alzheimer's disease, schizophrenia and narcolepsy. To date, however, no direct way to examine the activation of H3R has been utilized. Here, we describe a novel biosensor that can visualize the activation of H3R through an intramolecular fluorescence resonance energy transfer (FRET) signal. To achieve this, we constructed an intramolecular H3R FRET sensor with cyan fluorescent protein (CFP) attached at the C terminus and yellow fluorescent protein (YFP) inserted into the third intracellular loop. The sensor was found to internalize normally on agonist treatment. We measured FRET signals between the donor CFP and the acceptor YFP in living cells in real time, the results of which indicated that H3R agonist treatment (imetit or histamine) increases the FRET signal in a time‐ and concentration‐dependent manner with Kon and Koff values consistent with published data and which maybe correlated with decreasing cAMP levels and the promotion of ERK1/2 phosphorylation. The FRET signal was inhibited by H3R antagonists, and the introduction of mutations at F419A, F423A, L426A and L427A, once again, the promotion of ERK1/2 phosphorylation, was diminished. Thus, we have built a H3R biosensor which can visualize the activation of receptor through real‐time structure changes and which can obtain pharmacological kinetic data at the same time. The FRET signals may allow the sensor to become a useful tool for screening compounds and optimizing useful ligands.

    Abstract The inhibition of Aluminum (Al)-induced root tip cell elongation is a major cause of plant root elongation suppression. The inhibition of root tip cell elongation is caused by a disruption of cell wall component metabolism, growth signaling, or cellular damage. The aim of this study was to identify the proteins involved in the metabolism of the root cell wall components under Al stress in the Al-tolerant wheat (Triticum aestivum L.) cultivar ET8.Differentially expressed proteins of Al-tolerant wheat roots were screened via isobaric tags for relative and absolute quantification (iTRAQ). Furthermore, their expression changes were detected via RT-PCR analysis. The contents of major components of the cell wall and their changes in metabolic enzyme activities were also investigated.A total of 97 differentially expressed proteins from Al-tolerant wheat roots were screened and nine of these 97 proteins were root cell wall component related. The known nucleic acid sequences of proteins were 14-3-3 protein, the plasm membrane (PM) H+-ATPase, phospholipase D, peroxidase, and glycosyltransferase. For 14-3-3 protein, phospholipase D and peroxidase, the protein expression and mRNA expression were consistent with Al-treatment; however, for PM H+-ATPase and glycosyltransferase, the protein expression and mRNA expression were inconsistent under Al-stress. Furthermore, both cellulase activity and callase activity were down-regulated by Al stress, while the phenylalanineammonialyase (PAL), cinnamyl alcohol dehydrogenase (CAD), and peroxidase (POD) activities were up-regulated. Furthermore, the PM H+-ATPase activity was decreased in response to Al stress. In addition, the contents of callose, cellulose, lignin, and H2O2 varied significantly.The cell wall components, relative metabolism enzymes activity, and gene expression also changed followed by protein expression changed in response to Al stress. The results suggest that Al stress leads to marked variations in metabolic enzyme activity, carbohydrate content, followed by changes of root cell components in wheat roots.
