Previous studies have demonstrated that the phenolic monomer baicalin has antidepressant-like effects and decreases serum corticosterone levels.However,the mechanism by which baicalin regulates hyperactivity of HPA axis remains unclear. This work aimed to investigate the effects of baicalin on hyperactivity of HPA axis using the olfactory bulbectomised(OBX) rat model of depression. METHODS Animals were anaesthetised with 10% chloral hydrate(3.3 mL·kg^(-1),ip). Using disinfected surgical equipment,the skull covering the olfactory bulbs was exposed by a midline incision. Two burr holes(2 mm diameter) were drilled 8 mm anterior to the bregma and 2 mm lateral to the midline. Both olfactory bulbs were aspirated and the holes filled with glass ionomer cement. The scalp was sutured closed. Sham-operated rats underwent every surgical procedure except the aspiration of the bulbs. The animals received penicillin(8×10~5U) intramuscularly(0.2 mL/300 g) once per day for 3 d post-surgery to prevent infection,and were subsequently housed alone in polypropylene cages. The experiments continued after 14 d of rehabilitation. The following groups were used for experiments: sham-operated(underwent surgical procedure without aspiratedolfactory bulbs and administration of vehicle only),OBX-model(underwent every surgical procedure and administration of vehicle only),OBX-amitriptyline treated(10 mg·kg^(-1)),and OBX-baicalin treatment(20 and 40 mg·kg^(-1)). Amitriptyline and baicalin were dissolved in physiological saline. RESULTS We examined how baicalin altered OBX-induced changes in serum glucocorticoid level as wel as inflammatory responses,sirtuin 1(SIRT1) expression,and p65 acetylation in the hypothalamus. Similar experiments were performed to analyse the effects of baicalin on lipopolysaccharide-induced inflammatory responses inhypothalamus. CONCLUSION Our results indicate that activation of the SIRT1 in the hypothalamus contributes to hyperactivity of HPA axis,which can be alleviated by baicalin.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

The Es4 sandstones are mostly arkose and lithic arkose, rarely feldspathic litharenite, with an average mass fraction of quartz 51.6%, feldspar 33.8% and rock fragments 14.6% (Q51.6F33.8R14.6). They have an average framework composition (mass fraction) of quartz 57.10%, K-feldspar 5.76%, sodium-calcium feldspar 13.00%, calcite 5.77%, dolomite 5.63%, siderite 0.95%, pyrite 0.30%, anhydrite 0.04%, and clay mineral 11.46%. The diagenentic minerals typically include kaolinite, illite-smectite (I/S), illite, chlorite, authigenetic quartz and feldspar, and carbonate and pyrite. Es4 sandstone has undergone stages A and B of eodiagenesis, and now, it is experiencing stage A of mesodiagenesis. Reservoir quality is predominantly controlled by the mechanical compaction, for example, 45.65% of the original porosity loss is related to compaction. The original porosity loss related with cementation is only 26.00%. The reservoir quality is improved as a result of dissolution of feldspar, rock fragment and so forth. The porosity evolved from dissolution varies from 3% to 4%.展开更多

Amitriptyline and baicalin were dissolved in physiological saline. RESULTS We examined how baicalin altered OBX-induced changes in serum glucocorticoid level as wel as inflammatory responses,sirtuin 1(SIRT1) expression,and p65 acetylation in the hypothalamus. Similar experiments were performed to analyse the effects of baicalin on lipopolysaccharide-induced inflammatory responses inhypothalamus. CONCLUSION Our results indicate that activation of the SIRT1 in the hypothalamus contributes to hyperactivity of HPA axis,which can be alleviated by baicalin.
文摘OBJECTIVE Depression is one of the prevalent and prominent complex psychiatric diseases and the number of depressed patients has been on the rise globally during the recent decades.Xiaoyaosan,as a famous Chinese herbal formula,has been widely used in depression patients for a long time. 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.

文摘Petrographic analysis combined with various techniques, such as scanning electron microscopy and X-ray diffraction, was used to assess the timing of growth and original mineral cements, the controls on reservoir and reservoir quality of the fourth member sandstones of Shahejie formation (Es4). The Es4 sandstones are mostly arkose and lithic arkose, rarely feldspathic litharenite, with an average mass fraction of quartz 51.6%, feldspar 33.8% and rock fragments 14.6% (Q51.6F33.8R14.6). They have an average framework composition (mass fraction) of quartz 57.10%, K-feldspar 5.76%, sodium-calcium feldspar 13.00%, calcite 5.77%, dolomite 5.63%, siderite 0.95%, pyrite 0.30%, anhydrite 0.04%, and clay mineral 11.46%. The diagenentic minerals typically include kaolinite, illite-smectite (I/S), illite, chlorite, authigenetic quartz and feldspar, and carbonate and pyrite. Es4 sandstone has undergone stages A and B of eodiagenesis, and now, it is experiencing stage A of mesodiagenesis. Reservoir quality is predominantly controlled by the mechanical compaction, for example, 45.65% of the original porosity loss is related to compaction. The original porosity loss related with cementation is only 26.00%. The reservoir quality is improved as a result of dissolution of feldspar, rock fragment and so forth. The porosity evolved from dissolution varies from 3% to 4%.

文摘Sediments in the Liushagang Formation of Late Eocene form a group of key hydrocarbon play fairways in the Beibuwan Basin,South China Sea.As an important reservoir-forming combination,the Liushagang Formation consists of deltaic siliciclastic and show clear sedimentary cyclicity.According to paleontology research and stratigraphic correlation,the boundary between Liushagang Formation(Els)and Weizhou Formation(Ewz)is regarded as the Eocene-Oligocene boundary.The oxygen isotope dating for well cores from the top of the first Member of Liushagang Formation(Els1)and the bottom of the third Member of Weizhou Formation(Ewz3)give an isochron age of 35.2 Ma.Here,we use GR logging data as a paleoenvironmental proxy to conduct a detailed cyclostratigraphic study of the Els1 in the Bailian Sag,Fushan Depression.Power spectra,evolutionary fast Fourier transformation and wavelet analysis all reveal significant sedimentary cycles in Els1.The ratios of cycle wavelengths in these stratigraphic units are 21?5?2.8?1.2?1,and are interpreted as Milankovitch cycles of 400 ka and 96 ka eccentricity,52 ka obliquity,22ka and 19 ka precession cycles,respectively.An astronomical time scale is established by tuning filtered 96 ka eccentricity cycles to a target curve of Well L2 in the Bailian Sag.Based on regional stratigraphic framework,combined with seismic,cores and logging data,the HST of the first member of the Liushagang Formation(Els1)delta in Well L2 was divided into six parasequence sets named Ps1-Ps6.According to the spectrum analysis by Simple Lomb periodogram from PAST program packages,the sediment accumulation rate of each parasequence sets first increased and then decreased as time went by.The sediment accumulation rate of Ps4 reached the maximum(0.127 m/ka)during the most prosperous period of delta prograding.Finally,the duration of each period of parasequence sets and more accurate geological age were calculated on the basis of sediment accumulation rate.The ages of each depth are precisely estimated and provide new constraints on the Late Eocene.
文摘OBJECTIVE Takeda G protein-coupled receptor 5(TGR5)is recognized as a promising target for type 2 diabetes and metabolic syndrome;its expression has been demonstrat⁃ed in the brain and is thought to be neuroprotec⁃tive.Here,we hypothesize that dysfunction of central TGR5 may contribute to the pathogene⁃sis of depression.METHODS In well-established chronic social defeat stress(CSDS)and chronic restraint stress(CRS)models of depression,we investigated the functional roles of TGR5 in CA3 pyramidal neurons(PyNs)and underlying mech⁃anisms of the neuronal circuit in depression(for in vivo studies,n=10;for in vitro studies,n=5-10)using fiber photometry;optogenetic,chemoge⁃netic,pharmacological,and molecular profiling techniques;and behavioral tests.RESULTS Both CSDS and CRS most significantly reduced TGR5 expression of hippocampal CA3 PyNs.Genetic overexpression of TGR5 in CA3 PyNs or intra-CA3 infusion of INT-777,a specific agonist,protected against CSDS and CRS,exerting sig⁃nificant antidepressant-like effects that were mediated via CA3 PyN activation.Conversely,genetic knockout or TGR5 knockdown in CA3 facilitated stress-induced depression-like behav⁃iors.Re-expression of TGR5 in CA3 PyNs rather than infusion of INT-777 significantly improved depression-like behaviors in Tgr5 knockout mice exposed to CSDS or CRS.Silencing and stimula⁃tion of CA3 PyNs→somatostatin-GABAergic(gamma-aminobutyric acidergic)neurons of the dorsolateral septum circuit bidirectionally regulat⁃ed depression-like behaviors,and blockade of this circuit abrogated the antidepressant-like effects from TGR5 activation of CA3 PyNs.CON⁃CLUSION TGR5 can regulate depression via CA3 PyNs→somatostatin-GABAergic neurons of dorsolateral septum transmission,suggesting that TGR5 could be a novel target for developing antidepressants.

文摘Reservoirs can be developed in the sediment gravity flows.However,high quality reservoirs are found widespread in sediment gravity flows of Gangzhong area,Huanghua depression,Bohai Bay Basin,East China.Characteristics and formation of these reservoirs are key problems to be solved.Through comprehensive analysis of thin section petrography,scanning electron microscopy and X-ray diffraction,two distinct rules were obtained.1) These high quality reservoirs have apparent characteristics:lithology consists mainly of medium-fine grained sands; moderately-well sorted and rounded; intergranular pores dominating >70% of the entire pores,surface per unit pore volume reaches 15%; average porosity is 21% and average permeability is 55×10-3 μm2.2) Types of sedimentary microfacies and dissolution strongly control on the formation of high quality reservoirs.Main channels and sandy braided bars have the best reservoir properties.Because that sediments are mainly medium-fine grained sands in high-energy environments.The favorable primary porosity and permeability may promote calcite cementation and help to produce more secondary pores.Besides,at the depth of 2500-3200 m,basically matching threshold of oil generation,organic acid expelled when organic matter became mature,and H+ released during clay mineral transformation.These both result in the dissolution of calcite cements and create large volume pores,then physical properties improve correspondingly.Moreover,deep hydrothermal fluid intrusion may also have impacts on the development of secondary pores.

文摘OBJECTIVE Respiratory depression hinders the use of anaesthetics and sedative hypnotics.For emergency use,specific antagonists are currently administered to counteract respiratory depression.However,antagonists are often short-lasting and can have multiple unexpected side effects.A novel AMPA receptor modulator LCX001,synthesized by our Institute of Medicinal Chemistry,is expected to relieve suppressed respiration.To explore the mechanism and impact of LCX001 on protection against respiratory depression.METHODS LCX001 was tested to alleviate respiratory depression triggered by opioid,propofol and pentobarbital in the plethysmography recording.The acetic acid writhing and hot-plate tests were conducted to evaluate potential analgesic effect of LCX001.Binding assay and whole-cell recording were used to analyze the property of LCX001 on positive modulation.The function of AMPA receptors were determined by location of receptors inthe membrane and state of channel opening,and both processes were impressed by AMPA receptor regulatory proteins.According to the theory,the effect of LCX001 on the expression of stargazin was measured firstly by Western blotting.The variation of receptor surface location were observed by live cell imaging.The regulation on neuronal Ca2+and cell function was investigated intensively by Ca2+imaging to clarify mechanism of LCX001.RESULTS LCX001 effectively rescued and prevented opioid(fentanyl and TH-030418),propofol,and pentobarbitalinduced respiratory depression by strengthening respiratory frequency and minute ventilation by 30%-50% in rats.The acetic acid writhing test and hot-plate test revealed potent anti-nociceptive efficacy of LCX001 on increasing the inhibition rate and %MPE to 80% and 65% respectively,in contrast to some ampakines that did not affect analgesia.Furthermore,LCX001 potentiated[3 H]AMPA and L-glutamate binding affinity to AMPA receptors,and facilitated glutamateevoked inward currents in HEK293 cells stably expressing GluA2(R).At 10 mmol·L^(-1) glutamate evoked amplitudes,LCX001 at 100 μmol·L^(-1) increased the potency of glutamate induced currents by(1120 ± 60) pA,compared with that of(752 ± 35) pA in the control group.LCX001 also prominently promoted steady state/peak amplitude ratio.LCX001 significantly slowed down the desensitization rates of the AMPA ion channel,and inhibited current decay.Importantly,application of LCX001 generated a significant increase in GluA2(R) surface expression in a mechanism of stargazin up-regulation,and restrained opioidinduced abnormal intracel ular Ca2+load,which might participate in breathing modulation.CONCLUSION The typical positive modulatory impact and potential new mechanism of LCX001 might promote ampakines to be a therapeutic option for protection against respiratory depression.

文摘OBJECTIVE To examine whether long-form phosphodiesterase-4(PDE4)knockdown by lentiviral RNA construct containing a speci fi c micro RNA/mi RNAmir hairpin structure reversed depression-like symptoms caused by chronic unpredictable mild stress(CUMS)in mice.METHODS In this research,the study was performed on adult male C57 mice,weighing(25±5)g,kept in a controlled environment.CUMS animal model was used recapitulate a multiple of behavioral characteristics and biochemical states of depression in human.The forced swimming test(FST)and the tail suspension test(TST)were used to detectthe state of depression.Western blotting analysis was used to assess protein levels of c AMP response element binding protein(CREB,unphosphorylated and phosphorylated[p CREB])to explore the neurochemical mechanisms.RESULTS CUMS decreased c AMP levels(P<0.01)and produced depression-like symptoms in FST(P<0.01)and TST(P<0.01).Microinfusions of lentiviruses reversed CUMS-induced c AMP decline(P<0.05)and depression-like symptoms.Moreover,CUMS caused a significant reduction in protein kinase A and CREB phosphorylation,and brain-derived neurotrophic factor transcription,both of which were partially attenuated by lentivirus-mediated knockdown of PDE4D.Also,the phosphorylation of extracellular signal-regulated kinase 1/2 was reduced in CUMS-exposed mice,which was reversed by 4Dmi RNA treatment.Taken together,this study demonstrated that PDE4Dmi RNA improved the CUMS-induced depressionlike symptoms that might be related to the increase in hippocampal c AMP and p CREB expression.CONCLUSION Hence,PDE4D inhibitors can serve as potential antidepressants,and their antidepressant activity is partially mediated by the activation of c AMP signaling pathway in the hippocampus.In other words,long-form PDE4D knockdown may offer a promising treatment for major depression disorder.
