METHODS The FD with liver depression-spleen deficiency syndrome rat model was established through classic chronic mild unpredictable stimulation every day. XYS group rats received XYS 1 h before the stimulation. The models were assessed by parameters including state ofthe rat, weight, sucrose test result and open-field test result. After 3 wk, the stools of rats were collected and genomic DNA was extracted. PCR products of the V4 region of 16 S rD NA were sequenced using a barcoded Illumina paired-end sequencing technique. The primary composition of the microbiome in the stool samples was determined and analyzed by cluster analysis.RESULTS Rat models were successfully established, per data from rat state, weight and open-field test. The microbiomes contained 20 phyla from all samples. Firmicutes, Bacteroidetes, Proteobacteria, Cyanobacteria and Tenericutes were the most abundant taxonomic groups. The relative abundance of Firmicutes, Proteobacteria and Cyanobacteria in the model group was higher than that in the normal group. On the contrary, the relative abundance of Bacteroidetes in the model group was lower than that in the normal group. Upon XYS treatment, the relative abundance of all dysregulated phyla was restored to levels similar to those observed in the normal group. Abundance clustering heat map of phyla corroborated the taxonomic distribution. CONCLUSION The microbiome relative abundance of FD rats with liver depression-spleen deficiency syndrome was significantly different from the normal cohort. XYS intervention may effectively adjust the gut dysbacteriosis in FD.展开更多

However,the therapeutic mechanisms remain uncertain because of difficulty of depression pathophysiology and the lack of bioinformatic approach to understand the molecular connection. METHODS In this thesis,we applied a network pharmacology approach to explain the potential mechanisms between Xiaoyaosan and depression involved in oral bioavailability screening,drug-likeness assessment,caco-2 permeability,blood-brain barrier target recognition and network analysis. RESULTS 66 active compounds in Xiaoyaosan formula with favorable pharmacokinetic profiles are predicted as active compounds for anti-depression treatment. Network analyses show that these 66 compounds target 40depression-associated proteins including especially HTR2A,NR 3C1,MAOB,XDH and CNR2. These proteins are mainly involved in the neuroactive ligand-receptor interaction,serotonergic synapse,cAMP signaling pathways and calcium signaling pathways. CONCLUSION The integrated network pharmacology method is an effective approach to illustrate the anti-depression mechanisms of herbs,and this in silico approach can be applied in drug discovery.展开更多

[Ca^2＋]i of hippocampal neurons may raise rapidly with increased corticosterone concentrations, leading to apoptosis. The anti-depressant effects of Xiaoyaosan （Free and Easy Wanderer＇s Powder） may inhibit apoptosis by down regulating the [Ca^2＋]i overload. PC12 cells were containing with corticosterone to simulate neuronal injury, dosed with Xiaoyaosan-containing serum, and the following parameters were measured： apoptosis,[Ca^2＋]i overload, and changes in mitochondrial membrane potential （△ψm） and bioenergetics. High-dose Xiaoyaosan-containing serum （the dose of intragastric administration was 2.633 g herb/mL） not only inhibited morphological injury and cell apoptosis, but also suppressed [Ca^2＋]i overload induced by corticosterone. Xiaoyaosan also blocked the decrease in mitochondrial membrane potential and adenosine triphosphate levels induced by corticosterone. Xiaoyaosan dose-dependently suppresses corticosterone-induced apoptosis, potentially via inhibiting [Ca^2＋]ioverload, and prevents impaired mitochondrial bioenergetics by maintaining mitochondrial membrane potential and adenosine triphosphate production, providing a putative mechanism for its antidepressant effects.展开更多

In order to explain the antidepressive effect of Xiaoyaosan, all of the recent reports were sought out on the current situation of the antidepressive monomer compositions of Xi- aoyaosan and their mechanism. By exploring the relationship between the effects and the active ingredients, the mechanism and the active ingredients, the antidepressive active ingredients such as quercetin, isorhamnetin, isoliquiritigenin, saikosaponinA, saikosaponinD, glycyrrhiz- kaempferol, liquiritin, isoliquiritin, liquiritigenin, inate, paeoniflorin, albiflorin, ferulic acid, curcumin and their mechanism of antidepressive such as regulating the monoamine neurotransmitter systems, regulating the neuroendocrine system, affecting the neural plasticity and neu- affecting the cytokines level, anti-oxidative stress were rotrophic, affecting the cellular and molecular mechanisms , summarized. By the overview in the level of monomer rather than formulae, we uncovered the antidepressive mech- anism of Xiaoyaosan and further confirmed that Xiaoyaosan, as a classic antidepressive Chinese prescription, had many characteristics, such as multi-level , multi-channel, multi-target and so on .展开更多

Methods The UPLC-PDA chromatogram of Xiaoyaosan was compared with that of Angelica Sinensis Radix. The relative retention time of each peak and the Uhraviolet spectra providing by PDA were used in the analyses. Constituents were isola- ted from Angelica Sinensis Radix under the guidance of UPLC-PDA investigation. Structures of the isolates were elu- cidated by NMR techniques. Anti-depression effect was evaluated on glutamate-induced neurons. Results Five marker peaks of Xiaoyaosan fingerprint were belong to Angelica Sinensis Radix, and they were determined as conife- ryl ferulate（ I）, E-butylidenephthalide （ II）, ligustilide （III）, Z-butylidenephthalide （ IV ）, 14-Acetoxy-12-sene- cioyloxytetradeca-2E,8E,10E-trien-4,6-diyn-l-ol（V）. Compound V was isolated from the plants of Umbelliferae for the first time. Treatment with compound I, III, IV can protect PC12 and SH-SY5Y cell from glutamate-induced cytotoxicity. Antidepression bioactivity of compound I was first investigated. Conclusion UPLC-PDA guided iso-lation technique was confirmed to be a rapid and accurate method to identify the main active constituents from An- gelica Sinensis Radix contrubuting to Xiaoyaosan.展开更多
