Aim To study the effects of lentinan(LNT)on the metabolism of dendritic cells(DCs)by metabonomics, and uncover the potential mechanism of its regulation of DC function. Methods DC2.4 cells were co-incubated with LNT for 24 h, and the activity of the cells was detected by thiazolyl blue tetrazolium bromide(MTT)assay. The contents of interleukin-6(IL-6), tumor necrosis factorα(TNF-α)and interleukin-12(IL-12)in supernatant were detected by enzyme-linked immunosorbent assay(ELISA). The metabolic general changes of DC2.4 cells were detected by Ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-QTOF/MS), and the differential metabolites were analyzed by multi-distance covariates and bioinformatics, partial least squares-discriminant analysis(PLS-DA). Finally, metabolic pathway analysis was performed by MetaboAnalyst 5.0. Results LNT did not significantly inhibit the activity of DC2.4 cells at the dose of 25100 mg·L-1. LNT(100 mg·L-1)could significantly stimulate the secretion of IL-6, TNF-α and IL-12 in DC2.4 cells. 20 differential metabolites were identified in DC2.4 cells after being stimulated by LNT(100 mg·L-1), which involved 25 metabolic pathways including urea cycle, arginine and proline metabolism. Conclusion The regulation of LNT on DC function involves a variety of amino acid metabolism.

OBJECTIVE@#To compare the safety differences between Chinese medicine (CM) and Western medicine (WM) based on Chinese Spontaneous Reporting Database (CSRD).@*METHODS@#Reports of adverse events (AEs) caused by CM and WM in the CSRD between 2010 and 2011 were selected. The following assessment indicators were constructed: the proportion of serious AEs (PSE), the average number of AEs (ANA), and the coverage rate of AEs (CRA). Further comparisons were also conducted, including the drugs with the most reported serious AEs, the AEs with the biggest report number, and the 5 serious AEs of interest (including death, anaphylactic shock, coma, dyspnea and abnormal liver function).@*RESULTS@#The PSE, ANA and CRA of WM were 1.09, 8.23 and 2.35 times higher than those of CM, respectively. The top 10 drugs with the most serious AEs were mainly injections for CM and antibiotics for WM. The AEs with the most reports were rash, pruritus, nausea, dizziness and vomiting for both CM and WM. The proportions of CM and WM in anaphylactic shock and coma were similar. For abnormal liver function and death, the proportions of WM were 5.47 and 3.00 times higher than those of CM, respectively.@*CONCLUSION@#Based on CSRD, CM was safer than WM at the average level from the perspective of adverse drug reactions.

Objective:Metabolomics was used to analyze the brain tissue samples of model mice with chronic unpredictable mild stress (CUMS) depression, in order to find out the differential metabolites related to depression and to explore the possible antidepressant mechanism of iridoid part of Valerianae Jatamansi Rhizoma et Radix (IEFV). Method:Forty-two Kunming mice were randomly divided into 6 groups, including the normal group, the model group, the fluoxetine group (2.5 mg·kg-1) and the IEFV low, medium, and high dose groups (doses were 5.73, 11.47, 22.94 mg·kg-1, respectively). The behavioral and biochemical indicators of CUMS model mice were used for pharmacodynamic evaluation with IEFV and a positive drug (fluoxetine) as the intervention drugs. Then, the effect of IEFV on endogenous substances of the brain tissue in CUMS model mice were analyzed by nuclear magnetic resonance hydrogen spectrum (1H-NMR) metabolomics, and multivariate statistical analysis was used to identify the differential metabolites and to enrich the metabolic pathways involved in the differential metabolites. Result:After modeling, the immobility time of the model mice increased significantly, their sucrose preference rate and the excitatory neurotransmitters [5-hydroxytryptamine (5-HT) and norepinephrine (NE)] decreased significantly, indicating the success of modeling. The depression was relieved after IEFV administration, mainly manifested by the recovery of the immobility time, sucrose preference rate and the excitatory neurotransmitters (5-HT and NE). Principal component analysis (PCA) of endogenous metabolites in brain tissue showed that the model group could be significantly separated from the normal group, while the IEFV groups and fluoxetine group all showed a trend of deviating from the model group to the normal group, which was consistent with the behavioral results. The results of orthogonal partial least squares discriminant analysis (OPLS-DA) showed that there were 16 different metabolites between the model group and the normal group, including 12 water-soluble metabolites and 4 liposoluble metabolites. Seven potential metabolism pathways were obtained through MetPA analysis, including metabolism of phenylalanine, metabolism of phenylalanine, tyrosine and tryptophan, metabolism of taurine and hypotaurine acid, metabolism of alanine, aspartic acid and glutamic acid, biosynthesis of valine, leucine and isoleucine, metabolism of D-glutamine and D-glutamate and tricarboxylic acid cycle (TCA). IEFV-high dose group could significantly recall 11 differential metabolites. Conclusion:IEFV may play an antidepressant role mainly by affecting energy metabolism, amino acid metabolism and neurotransmitter levels, which provides a reference for further study on the antidepressant mechanism of IEFV.

The prescription of clinical curative effect has promoted the formation and development of the dominant diseases in traditional Chinese medicine, but it has been controversial for a long time because its mechanism has not been effectively explained. Breaking the gap between animal/cell research and clinical research, and understanding the mechanism of dominant diseases in traditional Chinese medicine based on evidence-based medicine has become an important breakthrough in this scientific issue. Therefore, based on evidence-based medicine, we established the research concept that "originating from clinic, testing in experiment, returning to clinic". Taking the classic formula (Jinqi Jiangtang formula) treating diabetes as an example to find characteristic markers of diabetes supported by evidence-based medicine from clinic. We used the reverse analysis strategy of the response of characteristic markers to explore the intervention mechanism of Jinqi Jiangtang formula on characteristic markers. Then, we verified the key signaling molecules of the metabolic regulation of the Jinqi Jiangtang formula in clinic. The research ideas and key technologies for the mechanism of treatment of diabetes by Jinqi Jiangtang formula based on evidence-based medicine are formed, and it is expected to provide research reference for explaining the mechanism of dominant diseases in traditional Chinese medicine based on evidence-based medicine.

Abstract Engyodontium album is a widespread pathogen that causes different kinds of dermatoses and respiratory tract diseases in humans and animals. In spite of its perniciousness, the basic genetic and molecular background of this species remains poorly understood. In this study, the mitochondrial genome sequence of E. album was determined using a high-throughput sequencing platform. The circular mitogenome was found to be 28,081 nucleotides in length and comprised of 17 protein-coding genes, 24 tRNA genes, and 2 rRNA genes. The nucleotide composition of the genome was A+T-biased (74.13%). Group-II introns were found in the nad1, nad5, and cob genes. The most frequently used codon of protein-coding genes was UAU. Isoleucine was identified as the most common amino acid, while proline was the least common amino acid in protein-coding genes. The gene-arrangement order is nearly the same when compared with other Ascomycota mitogenomes. Phylogenetic relationships based on the shared protein-coding genes revealed that E. album is closely related to the Cordycipitaceae family, with a high-confidence support value (100%). The availability of the mitogenome of E. album will shed light on the molecular systematic and genetic differentiation of this species.

Endocannabinoid receptor system is extensively expressed in the vertebrate retina. There are two types of cannabinoid receptors, CB1 and CB2. Activation of these two receptors by endocannabinoids N-arachidonoylethanolamide (anandamine, AEA) and 2-arachidonyl glycerol (2-AG) regulates multiple neuronal and glial ion channels, thus getting involved in retinal visual information processing. In this review, incorporating our results, we discuss the modulation of cannabinoid CB1 and CB2 receptors on retinal neuronal and glial ion channels and retinal synaptic transmission.

Angelicae Sinensis Radix, with nourishing Yin, promoting blood circulation, and moisturizing dryness functions, is commonly used in clinical medicine. In order to investigate the effects and mechanism of Angelica sinensis(AS) on Th1/Th2 and Th17/Treg in mice with asthma and Yin deficiency syndrome, asthmatic and Yin deficiency syndrome Balb/c mice models were established by injecting and inhaling ovalbumin(OVA) and thyroxin. The models were treated with dexamethasone(DXM), AS extract and AS extract+DXM, respectively. Pathological examination of lung tissues was conducted by HE staining, and ELISA was used to detect the levels of IL-4, IL-17, IFN-γ, TGF-β as well as retinoic acid receptor-related orphan receptor (RORγt). Results showed that AS could significantly improve the situation of inflammation infiltration, increase ratios of IFN-γ/IL-4 and TGF-β/IL-17, decrease the levels of RORγt in lung tissues. The AS+DXM group showed a best treatment effect. The results indicated that AS played a therapeutic role for asthma with Yin deficiency syndrome and improved airway inflammation by inhibiting the expression of RORγt in lung tissues and regulating the balance of Th1/Th2 and Th17/Treg.

Glaucoma, the second leading cause of blindness, is a neurodegenerative disease characterized by optic nerve degeneration related to apoptotic death of retinal ganglion cells (RGCs). In the pathogenesis of RGC death following the onset of glaucoma, functional changes of glutamate receptors are commonly regarded as important risk factors. During the past several years, we have explored the mechanisms underlying RGC apoptosis and retinal Müller cell reactivation (gliosis) in a rat chronic ocular hypertension (COH) model. We demonstrated that elevated intraocular pressure in COH rats may induce changes of various signaling pathways, which are involved in RGC apoptosis by modulating glutamate NMDA and AMPA receptors. Moreover, we also demonstrated that over-activation of group I metabotropic glutamate receptors (mGluR I) by excessive extracellular glutamate in COH rats could contribute to Müller cell gliosis by suppressing Kir4.1 channels. In this review, incorporating our results, we discuss glutamate receptor- mediated RGC apoptosis and Müller cell gliosis in experimental glaucoma.
