A total of 65 compounds were detected in rat bile, plasma and urine samples, including 11 parent compounds and 54 metabolites. The results indicated that glucuronidation, hydroxylation and methylation were the major metabolic pathways of the components of RPAE. Furthermore, the results of this work demonstrated that UPLC-Q-TOF/MS combined with MetaboLynx？ software and mass defect filtering （MDF） could provide unique high throughput capabilities for drug metabolism study, with excellent MS mass accuracy and enhanced MSE data acquisition. With the MSE technique, both precursor and fragment mass spectra can be simultaneously acquired by alternating between high and low collision energy during a single chromatographic run.展开更多

Methods: ET-1 was immobilized on the surfaces of IAQCM by using the new surface modification methods. The PR801 in the solution was detected by modified substrates and the specific binding between PR801 and ET-1 was studied. Results: The curves went up or down after adding PR801.There is specific binding between PR801 and ET-1. The bound mass were 0.458 ng/mm 2 and 133.54 ng/cm 2, respectively. There exists relatively good stability with these two methods. Conclusion: The affinity biosensors: IAQCM can be used to study the interaction mechanism between PR801 and ET-1, providing a new way to study the interaction mechanism of TCM. PR801 can bind ET-1 specifically in the experiments. Therefore, ET-1 is another target that PR801 can bind specifically besides thromboxane A 2.展开更多

Methods： Thirty-two Wistar rats were randomly divided into four groups： Sham-operation group, ischemla/ reperfusion group （I/R group ）, RPR-pretreatment group and hemin group. The model of intestinal ischemia/ reperfusion was established by clamping the superior mesenteric artery for 1 hour followed by 2-hour reperfusion. The effect of RPR on the expression of heme oxygenase-1 （HO-1） in lung tissues was detected by immunohistochemistry and morphometry computer image analysis. Arterial blood gas analysis, lung permeability index, malondialdehyde （MDA） and superoxide dismutase （SOD） contents in lungs were measured. The histological changes of lung tissue were observed under light microscope. Resalts： The expression of HO-1 in RPR-pretreatment group and hemin group was obviously higher than that in sham-operation group and I/R group （ P 〈 0.01 ）. The level of MDA and lung permeability index in RPR-pretreatment and hemin group were significantly lower than those in I/R group （P〈0.01 or P〈0.05）, while the activity of SOD in RPR-pretreatment and hemin group was obviously higher than that in I/R group （P〈0.01）. Under light microscope, the pathologic changes induced by I/R were significantly attenuated by RPR. Conclusion： Intestinal ischemia/reperfusion may result in acute lung injury and pretreatment with RPR injection can attenuate the injury. The protective effect of RPR on the acute lung injury is related to its property of inducing HO-1 expression and inhibiting lipid peroxidation.展开更多

Then they were randomly divided into five groups: 8 rats receiving 1 ml normal saline through the puncture needle (Group A),8 receiving 1 ml lipopolysaccharide (LPS, 2.5 mg/kg,Group B), 8 receiving LPS and RPR (30 mg/kg, pumped through the femoral vein for 2 hours, Group C ), 8 receiving RPR 2 hours before dripping LPS ( Group D),and 8 receiving hemin (75 μmol/L through intraperitoneal injection) 18 hours before dripping LPS (Group E). After 6 hours of LPS dripping, blood samples were obtained through the carotid artery to perform blood gas analysis,then all the rats were exsanguinated to death and specimens of lung tissues were obtained. The pathomorphological changes of the lung tissues were observed. The expression of p38 MAPK/iNOS/HO-1, the neutrophil ratio, protein content in alveolar irrigating solution and malonaldehyde (MDA) content in the lung tissues were also detected.Results: Compared with Group A, the expression of p38 MAPK, iNOS and HO-1 markedly increased in Groups B, C, D, and E (P ＜0.01). But in Groups C, D, and E,the expression of p38 MAPK and iNOS were significantly lower than that of Group B, while expression of HO-1 was obviously higher than that of Group B ( P ＜ 0.05 ). The protein content, the ratio of neutrophils in bronchoalveolar lavage fluid ( BALF), the content of MDA and the activities of serum NO in Group B were significantly higher than those of Group A ( P ＜ 0.01 ). There was a significant decrease in the level of arterial bicarbonate and partial pressure of oxygen in Group B (P ＜ 0.01). Compared with Group B, these indexes of lung injury were significantly lower while the levels of arterial bicarbonate and partial pressure of oxygen increased significantly in Groups C, D,and E (P ＜ 0.05 or P ＜ 0.01 ). Under light microscope, the pathological changes induced by LPS were significantly attenuated by RPR and hemin.Conclusions: The high expression of MAPK plays an important role in lipopolysaccharide-induced acute lung injury.

文摘Background:In a previous study,we found that Atractylodes macrocephala and Paeoniae radix(AM-PR)was useful for the alleviation of functional constipation(FC).However,the precise mechanism underlying the compatibility between AM and PR in the treatment of FC remains uncertain.This study aims to analyze the pharmacokinetic differences in the active ingredients in the blood of rat models with FC when applied individually and in combination with AM-PR.It also seeks to compare the changes in the content of the active ingredient when applied individually and in combination with in vitro AM-PR,further in-depth investigation into its material foundation in terms of pharmacokinetics,as well as the composition of the substance.Methods:Blood microdialysis samples were collected using microdialysis technology.These samples from rats with FC were compared after administration of AM,PR,and AM-PR.The concentration of the main active ingredients was determined using the Ultra Performance Liquid Chromatography-Tunable Ultraviolet(UPLC-TUV)method.The concentration of the main active ingredients of the decoction compatibility before and after combining AM-PR was also determined using the UPLC-TUV method.Results:Our findings reveal that upon combination,the time to maximum concentration(T_(max))of isochlorogenic acid A(ICA-A)and ataridolide Ⅱ(ATR-Ⅱ)T_(max)was prolonged,terminal elimination half-life(T_(1/2))was reduced,and maximum plasma concentrations(C_(max))increased.The T_(max)of ataridolide Ⅲ(ATR-Ⅲ)remained consistent,whereas its T_(1/2)and C_(max)were significantly reduced.Conversely,for peoniflorin(PAE),T_(max)occurred sooner,T_(1/2)was shortened,and C_(max)increased.The T_(max)for albiflorin(ALB)remained consistent,whereas T_(1/2)and C_(max)witnessed significant increases.The area under the moment curve(AUMC)(0-t)and AUMC(0-∞)of PAE,ALB,ICA-A,ATR-Ⅱ experienced an increase after AM-PR administration in rats,attributable to the heightened C_(max).In comparison to individual herb administration,the T_(max)of ALB was advanced in combination,the T_(max)of PAE remained unchanged,and the T_(max)of ICA-A and ART-Ⅱ was delayed,with an increased area under the concentration-time curve(AUC)(0-t),indicating enhanced C_(max)and bioavailability.Furthermore,the dissolution rates of PAE,ICA-A,and ATR-Ⅱ significantly improved after compatibility.Conclusions:This study partially clarifies the rationale and compatibility of AM-PR in treating FC and offers a new perspective on the pharmacokinetic interactions of AM-PR in FC treatment.

文摘The present study was designed to investigate the therapeutic effcts of Moutan Cortex(CM,root bark of Paeonia suffruticosa Andr) and Paeoniae Radix Rubra(PR,root of Paeonia veitchii Lynch) on metabolic disorders,focusing on the infuence of CM and PR on the obesity-related gut microbiota homeostasis.The diet-induced obese(DIO) mouse model was used to test the therapeutic effects of CM and PR.The mice were orally administered with CM and PR for 6 weeks,and oral glucose tolerance test(OGTT) and insulin tolerance test(ITT) were performed to evaluate the insulin sensitivity of the mice.Sterol-regulatory element binding proteins(SREBPs) and their target genes were measured by quantitative RT-PCR.High-throughput 16 S ribosomal RNA(16S rR NA) gene sequencing technology was used to determine the composition of gut microbiota,and the metabolites in serum were analyzed by GC-MS.Our results indicated that CM and PR combination alleviated obese and insulin resistance in the DIO mice,leading to increased glucose uptake and gene expression in muscle and liver,and down-regulated SREBPs and their target genes in liver.Interesting,neither the CM-PR extracts,nor the major components of CM and PR did not affect SREBPs activity in cultured cells.Meanwhile,CM and PR significantly modulated the gut microbiota of the high-fat diet(HFD) treated mice,similar to metformin,and CM-PR reversed the overall microbiota composition similar to the normal chow diet(NCD) treated mice.In conclusion,our results provide novel mechanisms of action for the effects of CM and PR in treating DIO-induced dysregulation of sugar and lipid metabolism.

文摘Radix Bupleuri(RB)is commonly used to treat depression,but it can also lead to hepatotoxicity after longterm use.In many anti-depression prescriptions,RB is often used in combination with Radix Paeoniae Alba(RPA)as an herb pair.However,whether RPA can alleviate RB-induced hepatotoxicity remain unclear.In this work,the results confirmed that RB had a dose-dependent antidepressant effect,but the optimal antidepressant dose caused hepatotoxicity.Notably,RPA effectively reversed RB-induced hepatotoxicity.Afterward,the mechanism of RB-induced hepatotoxicity was confirmed.The results showed that saikosaponin A and saikosaponin D could inhibit GSH synthase(GSS)activity in the liver,and further cause liver injury through oxidative stress and nuclear factor kappa B(NF-kB)/NOD-like receptor thermal protein domain associated protein 3(NLRP3)pathway.Furthermore,the mechanisms by which RPA attenuates RBinduced hepatotoxicity were investigated.The results demonstrated that RPA increased the abundance of intestinal bacteria with glycosidase activity,thereby promoting the conversion of saikosaponins to saikogenins in vivo.Different from saikosaponin A and saikosaponin D,which are directly combined with GSS as an inhibitor,their deglycosylation conversion products saikogenin F and saikogenin G exhibited no GSS binding activity.Based on this,RPA can alleviate the inhibitory effect of saikosaponins on GSS activity to reshape the liver redox balance and further reverse the RB-induced liver inflammatory response by the NFkB/NLRP3 pathway.In conclusion,the present study suggests that promoting the conversion of saikosaponins by modulating gut microbiota to attenuate the inhibition of GSS is the potential mechanism by which RPA prevents RB-induced hepatotoxicity.
文摘Ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry （UPLC-Q-TOF/MS） was developed to identify the absorbed parent components and metabolites in rat bile, plasma and urine after oral administration of Radix Paeoniae Alba extract （RPAE）. A total of 65 compounds were detected in rat bile, plasma and urine samples, including 11 parent compounds and 54 metabolites. The results indicated that glucuronidation, hydroxylation and methylation were the major metabolic pathways of the components of RPAE. Furthermore, the results of this work demonstrated that UPLC-Q-TOF/MS combined with MetaboLynx？ software and mass defect filtering （MDF） could provide unique high throughput capabilities for drug metabolism study, with excellent MS mass accuracy and enhanced MSE data acquisition. With the MSE technique, both precursor and fragment mass spectra can be simultaneously acquired by alternating between high and low collision energy during a single chromatographic run.

文摘OBJECTIVE:To elucidate the potential molecular mechanisms of Baishao(Radix Paeoniae Alba)(APR)and Gancao(Radix Glycyrrhizae)(GR)in the treatment of major depressive disorder(MDD).METHODS:Based on the network pharmacology strategy,the therapeutic targets of APR-GR for MDD are predicted,differentially expressed genes from the Integrated Gene Expression database for MDD patients.Topological networks are constructed,Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathways are enriched,their pharmacological potential molecular mechanisms are discussed,and molecular docking analysis is performed to further motivate compositional and target interactions.Finally,the CUMS mouse model is used for validation.RESULTS:Based on the pharmacological network analysis,17 candidate genes were identified,including muscarinic acetylcholine receptor M1(CHRM1),muscarinic acetylcholine receptor M2(CHRM2),β2-adrenergic receptor(ADRB2),adrenergicα1A receptor(ADRA1A)and 5-hydroxytryptamine transfer protein(SLC6A4),etc.which are primarily involved in reactive oxygen species metabolism,neural response,oxidative stress response and other biological processes.Further analysis revealed that these targets are closely related to Ca^(2+),cyclic adenosine monophosphate,etc.,and exhibit optimal binding sites after molecular docking.Finally,in vivo experiments were performed and it was found that APR-GR significantly improved depression-like behavior and hippocampal impairment in mouse models,increasing brain levels of 5-hydroxytryptamine,dopamine and norepinephrine and decreasing serum levels of corticotropin releasing hormone,corticosterone and adreno cortico tropic hormone,while upregulating the expression of CHRM1,CHRM2 and ADRA1A in the hippocampus and downregulating the expression of SLC6A4 and ADRB2.CNCLUSION:This research sheds light on the potential molecular mechanism of APR-GR to improve MDD.
文摘Objective： To investigate the effect of pretreatment with Radix Paeoniae Rubra （RPR） on acute lung injury induced by intestinal ischemia/reperfusion in rats and its protective mechanism. Methods： Thirty-two Wistar rats were randomly divided into four groups： Sham-operation group, ischemla/ reperfusion group （I/R group ）, RPR-pretreatment group and hemin group. The model of intestinal ischemia/ reperfusion was established by clamping the superior mesenteric artery for 1 hour followed by 2-hour reperfusion. The effect of RPR on the expression of heme oxygenase-1 （HO-1） in lung tissues was detected by immunohistochemistry and morphometry computer image analysis. Arterial blood gas analysis, lung permeability index, malondialdehyde （MDA） and superoxide dismutase （SOD） contents in lungs were measured. The histological changes of lung tissue were observed under light microscope. Resalts： The expression of HO-1 in RPR-pretreatment group and hemin group was obviously higher than that in sham-operation group and I/R group （ P 〈 0.01 ）. The level of MDA and lung permeability index in RPR-pretreatment and hemin group were significantly lower than those in I/R group （P〈0.01 or P〈0.05）, while the activity of SOD in RPR-pretreatment and hemin group was obviously higher than that in I/R group （P〈0.01）. Under light microscope, the pathologic changes induced by I/R were significantly attenuated by RPR. Conclusion： Intestinal ischemia/reperfusion may result in acute lung injury and pretreatment with RPR injection can attenuate the injury. The protective effect of RPR on the acute lung injury is related to its property of inducing HO-1 expression and inhibiting lipid peroxidation.

文摘Objective: To investigate the effect of radix paeoniae rubra (RPR) on expression of p38 mitogen activated protein kinase ( MAPK )/iNOS/HO-1 in rats with lipopolysaccharide-induced acute lung injury and explore the molecular mechanism.Methods: Forty healthy male Wistar rats, weighing 200-250 g, aged 6-8 weeks (mean =7 weeks), provided by the Experimental Center, Medical College, Wuhan University, Wuhan, China, were employed in this study.Under anesthesia with 7% chloraldurat (5 ml/kg body weight) through intraperitoneal injection, the trachea of the rat was exposed and an arterial puncture needle pricked into the trachea via cricothyroid membrane. Then they were randomly divided into five groups: 8 rats receiving 1 ml normal saline through the puncture needle (Group A),8 receiving 1 ml lipopolysaccharide (LPS, 2.5 mg/kg,Group B), 8 receiving LPS and RPR (30 mg/kg, pumped through the femoral vein for 2 hours, Group C ), 8 receiving RPR 2 hours before dripping LPS ( Group D),and 8 receiving hemin (75 μmol/L through intraperitoneal injection) 18 hours before dripping LPS (Group E). After 6 hours of LPS dripping, blood samples were obtained through the carotid artery to perform blood gas analysis,then all the rats were exsanguinated to death and specimens of lung tissues were obtained. The pathomorphological changes of the lung tissues were observed. The expression of p38 MAPK/iNOS/HO-1, the neutrophil ratio, protein content in alveolar irrigating solution and malonaldehyde (MDA) content in the lung tissues were also detected.Results: Compared with Group A, the expression of p38 MAPK, iNOS and HO-1 markedly increased in Groups B, C, D, and E (P ＜0.01). But in Groups C, D, and E,the expression of p38 MAPK and iNOS were significantly lower than that of Group B, while expression of HO-1 was obviously higher than that of Group B ( P ＜ 0.05 ). The protein content, the ratio of neutrophils in bronchoalveolar lavage fluid ( BALF), the content of MDA and the activities of serum NO in Group B were significantly higher than those of Group A ( P ＜ 0.01 ). There was a significant decrease in the level of arterial bicarbonate and partial pressure of oxygen in Group B (P ＜ 0.01). Compared with Group B, these indexes of lung injury were significantly lower while the levels of arterial bicarbonate and partial pressure of oxygen increased significantly in Groups C, D,and E (P ＜ 0.05 or P ＜ 0.01 ). Under light microscope, the pathological changes induced by LPS were significantly attenuated by RPR and hemin.Conclusions: The high expression of MAPK plays an important role in lipopolysaccharide-induced acute lung injury. Protective effect of RPR on lipopolysaccharideinduced acute lung injury may be related to the inhibition of the abnormal high expression of p38 MAPK/iNOS/HO-1.
