Mechanism of Baihu Renshen decoction on T2DM rats based on mitochondrial autophagy mediated by PINK1/Parkin

Background:This study will be aimed at investigating the effects of Baihu Renshen decoction(BHRS)on type 2 diabetes rats and on macromolecular enzyme 1(PINK1)/E3 ubiquitin protein ligase(Parkin)pathway.Methods:The experiment was divided into four groups:control group,model group,metformin group and BHRS low-dose group and high-dose group.Forty male rats were selected as samples and randomly assigned to at least one test group.Finally,there are 18 rats in each group.Except for the control group,the rats within the different teams got a high-fat diet associate in nursing an intraperitoneal injection of streptozotocin to make a type 2 diabetes mellitus(T2DM)rat model.The organic chemistry and inflammatory indexes of rats in every cluster were analyzed and compared once four weeks of intragastric administration of comparable reagents to review the therapeutic impact of BHRS on T2DM.In addition,we determined the pathological changes of ductal gland tissue of T2DM rats after treatment,and compared the expression of mitochondrial phagocytosis related proteins in ductal gland tissue of rats in each group.Results:FBG,LDL-C,TC,TG,MDA,IL-1,IL-6,TNF-,and mitophagy-related proteins COXIV,P62,VDAC1,and TOM20 were elevated in the model group compared to the control group,while HDL-C,SOD,GSH-Px,and mitophagy-related proteins PINK1,Parkin,and LC3II/I were decreased(P<0.05 or P<0.01).The expressions of FBG,TC,TG,LDL-C,MDA,IL-1,IL-6,TNF-,and mitophagy-related proteins COXIV,P62,VDAC1,and TOM20 were lowered in the BHRS group,while the expressions of HOMA-,HDL-C,SOD,GSH-Px,and mitophagy-related proteins PINK1,Parkin,and LC3II/I were(P<0.05 or P<0.01).After therapy with BHRS,hematoxylin-eosin staining showed that the intensity of pancreatic acinar staining increased,and islet cells became clear boundaries that were,regularly arranged,and with reduced vacuoles reduced.Conclusion:BHRS has a clear therapeutic effect on T2DM,which may be achieved by regulating mitochondrial autophagy through the PINK1/Parkin pathway.

Objective：To explore the effect of Renshen Yangrong Decoction（人参养荣汤,RYD） in protecting bone marrow from radiation injury.Methods：One hundred and eighty Kuming mice were subjected to the three tests for anti-radiation injury effect evaluation,i.e.the test of peripheral white blood cell（WBC） count, the test of bone marrow nucleated cell count,and the bone marrow micronucleus test,using 60 mice for each test.The mice in each test were divided into 6 groups：the blank control group,the model control group,the positive control group treated by Shiyiwei Shenqi Tablet（十一味参芪片,1.0 g/kg）,and three RYD groups treated with high（42.0 g/kg）,moderate（21.0 g/kg）,and low（10.5 g/kg） doses of crude drugs of RYD,with 10 mice in each group.The treatment was given by gastrogavage perfusion continuously for 7-14 days before mice received ^（60）Co-γray radiation and continued until the end of the experiment.The body weights of the mice were monitored,the changes in peripheral WBC and bone marrow nucleated cells were counted,and the variation in bone marrow micronucleated cells was observed on the respective appointed days.Results：A significant decrease in body weight,peripheral WBC count,and bone marrow nucleated cell count,as well as marked changes in bone marrow micronucleated cells were observed in the mice after radiation,indicating that the radiation injury model was successfully established.As compared with the model control group,the decrease in body weight,peripheral WBC count,and bone marrow nucleated cell count,as well as the increase in bone marrow micronucleus cell count in the high dosage RYD treated group were obviously inhibited or lessened （P0.05 or P0.01）.Conclusion：RYD showed obvious protective effect in mice with bone marrow injury induced by radiation.

Efficacy of Renshen(Radix Ginseng) plus Fuzi(Radix Aconiti Lateralis Preparata) on myocardial infarction by enhancing autophagy in rats

OBJECTIVE:To elucidate the protective effects of Renshen(Radix Ginseng)and Fuzi(Radix Aconiti Lateralis Preparata)on myocardial infarction(MI)through regulating myocardial autophagy.METHODS:Thirty-one male Sprague-Dawley rats were randomized into five groups(n=6 or 7 for each).After treatment for 3 weeks,electrocardiogram(ECG)and cardiac function were recorded.Hematoxylin and eosin(HE)staining was used to detect pathological changes in the heart.Enzyme-linked immunosorbent assay(ELISA)was used to detect serum B-type brain natriuretic peptide(BNP),cardiac troponin T(c Tn T),tumor necrosis factor-α(TNF-α),and serum inflammatory cytokines.Metabolomic analysis was used to identify differential biomarkers of MI in rats.Immunohistochemistry and western blotting were used to detect BNP,cTnT,TNF-α,LC3B,Beclin-1,p62,and adenosine monophosphate activated protein kinase(AMPK)expression in cardiac tissue.RESULTS:Fuzi(Radix Aconiti Lateralis Preparata)alone or Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)markedly ameliorated cardiac dysfunction and abnormal ECGs,demonstrated by decreases in the heart weight/body weight ratio,BNP,and c Tn T.Pro-inflammation cytokine interleukin(IL)-1αsignificantly decreased and anti-inflammatory cytokine IL-10 significantly increased in Renshen(Radix Ginseng)single or Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)groups compared with the control group.HE results suggested that co-treatment produced a greater reduction in cardiomyocyte cross-sectional area than Renshen(Radix Ginseng)or Fuzi(Radix Aconiti Lateralis Preparata)alone.Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)reversed these changes to different degrees in MI rats.Furthermore,Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)down-regulated LC3 B,Beclin-1,and AMPK expression in cardiac tissue and upregulated p62 expression.CONCLUSIONS:Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)may have a greater effect on heart injury induced by MI in rats than Fuzi(Radix Aconiti Lateralis Preparata)treatment alone,and the underlying mechanism may be associated with the regulation of myocardial autophagy and anti-inflammation effects.These results provide fresh insight into the mechanism of co-treatment with Renshen(Radix Ginseng)and Fuzi(Radix Aconiti Lateralis Preparata)for MI.

基于一气周流理论探讨苓蔻人参汤在溃疡性结肠炎治疗中的应用

溃疡性结肠炎(Ulcerative Colitis,UC)是消化系统的常见病和多发病,病情容易反复发作、迁延难愈,严重影响患者的生活和健康,成为临床上难治性疾病之一。清代著名医家黄元御在《四圣心源》中提出“一气周流”理论,以“人体心、肝、肺、肾皆由脾胃所化生,人体气机以中土为轴,肝肾之气左升,心肺之气右降,循环周流”为主要内容。根据黄元御“一气周流”的学术思想探讨UC的病机和治法,认为UC的病机关键为水寒土湿,肝郁脾陷。基于以上的病机认识,本病的治疗应从整体把握脾、肝、肾等多脏气机的全局变化,在以温阳健脾,斡旋中气为临床治疗和遣方用药原则的同时,结合具体情况灵活施治,治理源头的同时兼及四维,以求达到土干、木达、水暖,帮助恢复人体一气的流通,使人体阴阳气血随着“周流之气”按部就班地各司其职,以求阴阳相济、气血归和,从而达到人即安和的状态。苓蔻人参汤出自《四圣心源》,为治疗泄利的经典方剂,其依理立方基于“木郁、土湿、水寒”的基本病机,通过条达肝气,益气补中,燥化水湿,以恢复人体的“一气周流”,在一定程度上能缓解甚至治愈疾病,为临床治疗UC提供了新的思路,值得后世医者的进一步研悟借鉴。

Efficacy of Renshen Sanqi Chuanxiong formula for preventing vascular aging

OBJECTIVE:To evaluate the efficacy of Renshen Sanqi Chuanxiong formula(RSCF)for preventing vascular aging,and to investigate the possible molecular mechanism underlying the actions of RSCF.METHODS:Potentially active components and their relatively direct targets were identified by combining drug-likeness(DL)screening using a target identification process.Vascular aging-associated targets for RSCF were obtained by selecting common genes not only from potential targets but also from human vascular aging-associated genes.Cytoscape 3.2.1 software was employed to visualize the complex compound-target and target-function networks.Biological process and molecular function were assessed,and the Kyoto Encyclopedia of Genes and Genomes and pathway enrichment analyses were performed using Clue GO.Pathways directly associated with vascular aging were integrated into a"vascular aging-related"pathway.RESULTS:Altogether,122 potentially active components of RSCF were identified through DL screening,and their corresponding 692 direct targets were retrieved via target prediction and identification.We identified 49 vascular aging-associated targets for RSCF by overlapping the 692 potential targets with 146 human vascular aging-associated genes.The results from the compound-target network indicated that most components acted on common targets and displayed synergistic action,which showed that the magnifying effects of RSCF were based on these common targets.The target-function network revealed that each target was involved in multiple function modules,suggesting that RSCF was multi-functional during treatment of vascular aging.The results of the Clue GO analysis indicated that most of the targets were associated with the hypoxia-inducible factor 1(HIF-1)signaling pathway.The results from the pathway analysis also indicated that an integrative vascular aging-related pathway mainly included an angiogenesis regulation module,cell-survival module,and oxidative stress-resistance module.CONCLUSION:Our results suggested that many components act synergistically on common targets to delay vascular aging,and each target is involved in multiple functional modules.The Clue GO analysis indicated that most of the targets were connected to the HIF-1 signaling pathway,FOXO signaling pathway,and thyroid hormone signaling pathway.

Effects of extracts from Renshen(Radix Ginseng), Sanqi(Radix Notoginseng), and Chuanxiong(Rhizoma Chuanxiong) on F-actin in senescent microvascular endothelial cells

OBJECTIVE: To investigate the effects of extracts from Renshen(Radix Ginseng), Sanqi(Radix Notoginseng), and Chuanxiong(Rhizoma Chuanxiong) on the endothelial actin cytoskeleton in senescent human cardiac microvascular endothelial cells(HCMECs), and to propose the possible mechanism underlying the actions.METHODS: Lentiviral mediated RNA interference was applied to a replicative senescent HCMEC model by knocking down heat shock protein 27(HSP27)gene. Cells were treated with extracts from Renshen(Radix Ginseng), Sanqi(Radix Notoginseng), and Chuanxiong(Rhizoma Chuanxiong) at final concentrations of 50, 100, and 200 mg/L, respectively and with 10 μM resveratrol for 48 h. Untreated cells were used as controls. Senescence was detected by senescence β-galactosidase staining and cell proliferation was analyzed by cell counting kit-8 assays.Secreted nitric oxide levels were detected by nitrate reductase. Morphological changes of F-actin and G-actin were observed by laser scanning confocal microscopy. Protein and gene expression of Factin and HSP27 was detected by western blotting.RESULTS: Compared with the control group, the proportion of senescent HSP27 shRNA cells treated with the extracts was decreased and their proliferation was increased. In the extract intervention group, F-actin around the cell periphery became irregular and jagged fractures formed gradually and then dissipated. Moreover, some dynamic actin stress fiber filaments appeared. The G-actin stretched to the cell periphery and punctate staining was scattered in the cytoplasm. In addition, the mean optical density value of F/G-actin was decreased significantly and the protein expression of F-actin was downregulated.CONCLUSION: The extracts delayed microvascular endothelial cell senescence by downregulating the expression of F-actin through HSP27.
