Network pharmacology-based strategy for predicting therapy targets of Sanqi and Huangjing in diabetes mellitus

BACKGROUND A comprehensive literature search shows that Sanqi and Huangjing(SQHJ)can improve diabetes treatment in vivo and in vitro,respectively.However,the combined effects of SQHJ on diabetes mellitus(DM)are still unclear.AIM To explore the potential mechanism of Panax notoginseng(Sanqi in Chinese)and Polygonati Rhizoma(Huangjing in Chinese)for the treatment of DM using network pharmacology.METHODS The active components of SQHJ and targets were predicted and screened by network pharmacology through oral bioavailability and drug-likeness filtration using the Traditional Chinese Medicine Systems Pharmacology Analysis Platform database.The potential targets for the treatment of DM were identified according to the DisGeNET database.A comparative analysis was performed to investigate the overlapping genes between active component targets and DM treatmentrelated targets.We constructed networks of the active component-target and target pathways of SQHJ using Cytoscape software and then analyzed the gene functions.Using the STRING database to perform an interaction analysis among overlapping genes and a topological analysis,the interactions between potential targets were identified.Gene Ontology(GO)function analyses and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were conducted in DAVID.RESULTS We screened 18 active components from 157 SQHJ components,187 potential targets for active components and 115 overlapping genes for active components and DM.The network pharmacology analysis revealed that quercetin,beta-sitosterol,baicalein,etc.were the major active components.The mechanism underlying the SQHJ intervention effects in DM may involve nine core targets(TP53,AKT1,CASP3,TNF,interleukin-6,PTGS2,MMP9,JUN,and MAPK1).The screening and enrichment analysis revealed that the treatment of DM using SQHJ primarily involved 16 GO enriched terms and 13 related pathways.CONCLUSION SQHJ treatment for DM targets TP53,AKT1,CASP3,and TNF and participates in pathways in leishmaniasis and cancer.

Effect of Sanqi Oral Liquid on the Expressions of CD4＋, CD8＋ and CD68＋Cells in 5/6 Nephrectomized Rats with Chronic Renal Failure~

Objective： To explore the mechanisms of Chinese herbal medicine Sanqi Oral Liquid , composed of Astragalus membranaceus and Panpax notoginseng, in alleviating renal injury by observing its effect on the expressions of CD4＋, CD8＋ and CD68＋ cells in 5/6 nephrectomized rats with chronic renal failure. Methods： A total of 102 SD rats were randomly divided into six groups： three treatment groups were administrated with high, medium and low dosage of Sanqi Oral Liquid respectively by gavage; a normal group, a 5/6 nephrectomized model group, and a group treated with coated aldehyde oxygenstarch were used as controls. Following oral administration of Sanqi Oral Liquid for 12 weeks, the general condition and renal pathological changes were observed, and the renal function, platelet count （PLT） and the expressions of CD4~, CD8＊ and CD68~ cells were determined for each group. Results： There were proliferation of mesangial matrix, renaltubularnecrosis and obvious tubulointerstitial fibrosis in the model group, and they were much milder in the treatment groups. Compared with the model group, the amounts of blood urea nitrogen （BUN）, serum creatinine （Scr） and PLT in the treatment groups decreased （P〈0.05 for all）; and in the group administrated of medium dosage of Sanqi Oral Liquid, the expression of CD4＋ cells was up-regulated and those of CD8＋ and CD68＋ cells were down-regulated （P〈0.05 for all）, leading to an increased ratio of CD4＋/CD8＋ （P〈0.01）. Conclusion： Sanqi Oral Liquid has a significant effect on regulating lymphocyte subsets, reducing the infiltration of macrophages in renal tissues and alleviating tubulointerstitial fibrosis, and this may be one of mechanisms of Sanqi Oral Liquid in delaying the progression of chronic kidney diseases.

Blood circulation activating effect of Sanqi(Radix Notoginseng) on venous thromboembolism rats

OBJECTIVE:To explore the blood circulation activating effect and mechanism of Sanqi(Radix Notoginseng)in vivo,using a venous thromboembolism(VTE)rat model.METHODS:We established the VTE rat model,and then intervened with low molecular weight hepa-rin(LMWH),as well as low,medium and high doses of Sanqi(Radix Notoginseng),to observe the blood circulation activating effect of Sanqi(Radix Notoginseng)on VTE rats.RESULTS:After the treatment with high concentrations of Sanqi(Radix Notoginseng),the pulmonary thromboembolism was alleviated,and the lower limb thrombosis was markedly improved.Moreover,the expression quantities of plasma activated partial thromboplastin time,prothrombin time and D-dimer,as well as endothelin,von Willebrand factor,and plasminogen activator inhibitor-1 in thrombosis segment tissues were markedly down-regulated;while those of nitric oxide and tissue-type plasminogen activator were up-regulated.After low and medium concentration Sanqi(Radix Notoginseng)treatment,no obvious improvement was observed in each index.Moreover,the high concentration Sanqi(Radix Notoginseng)showed comparable efficacy to the positive drug LMWH.CONCLUSION:This data suggests that high concentration of Sanqi(Radix Notoginseng)is effective in preventing and treating VTE.

Efficacy of Sanqi(Radix Notoginseng)in treating cerebral hemorrhage in rats with traumatic brain injury

OBJECTIVE:To evaluate the protective efficacy of Sanqi(Radix Notoginseng)on cerebral hemorrhage in a rat model of traumatic brain injury(TBI)by investigating plasminogen activator inhibitor-1(PAI-1),tissue-type plasminogen activator(t-PA),nuclear factor-κB(NF-κB,p-p65),nitric oxide(NO),endothelin(ET),cluster differentiation(CD61CD62),and coagulation.METHODS:The free-fall method was used to create a rat model of TBI.Forty-eight rats were randomly divided into six groups:the blank group,sham group,model group,low-dose Sanqi(Radix Notoginseng)group,middle-dose Sanqi(Radix Notoginseng)group,and high-dose Sanqi(Radix Notoginseng)group.At 24 h after the model was created,we investigated brain MRI,brain tissue morphology using HE staining,flow cytometry,and immunohistochemical changes.RESULTS:Cerebral hemorrhage was aggravated in TBI rats(observed in brain specimens,brain MRI,and brain tissue HE).Cerebral immunohistochemistry results demonstrated that the expression of t-PA,PAI-1 and p-p65 increased significantly in TBI rats,while t-PA/PAI-1 had a significant decrease.In addition,CD61CD62,D2D,and ET were significantly increased in TBI rats,and PT and APTT were significantly prolonged;in contrast,NO was significantly decreased.Sanqi(Radix Notoginseng)decreased cerebral hemorrhage in TBI rats(observed in brain MRI and brain tissue HE),and increased t-PA/PAI-1,CD61CD62 significantly.It also significantly decreased the expression of t-PA,PAI-1,and p-p65 in brain immunohistochemistry and significantly decreased PT,APTT,D2D,and ET.However,there were no differences in NO between the model group and the Sanqi(Radix Notoginseng)group.CONCLUSION:Sanqi(Radix Notoginseng)can decrease the expression of p-p65,increase t-PA/PAI-1,and stem traumatic intracranial hemorrhage in a TBI rat model.

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.

Neuroprotective effect of Sanqi Tongshuan Tablets on sequelae post-stroke in rats

Objective: To identify the therapeutic effect and possible mechanisms of Chinese medicine Sanqi Tongshuan Tablets(SQTS) on sequelae post-stroke in rats.Methods: The rat cerebral ischemia sequelae post-stroke models were successfully induced by blocking the middle cerebral artery with electric coagulator after the seventh week and balance beam test ≤ 4. The rats were then received with SQTS(0.5, 1, and 2 g/kg) and Naodesheng(NDS, 1.24 g/kg), Vinpocetine(VP,1.55 mg/kg) for 30 d. The beam-walking test and shuttle test were performed before and after 10, 20, and 30 d of administration. In addition, histopathology changes and GAP-43, GFAP were measured by H&E staining and immunohistochemisty.Results: The model displayed signs of brain damage on motor function, learning and memory function and histopathology. After 30 d of treatment, SQTS at different doses(0.5, 1.0, and 2.0 g/kg) restored the beam-walking scores by 21.7%(P > 0.05), 30.4%(P > 0.05), and 39.1%(P < 0.05); Decreased electric shock by 35.0%(P > 0.05), 50.0%(P > 0.05), and 75.0%(P < 0.05), respectively. On the other hand, the histological changes were less severe and the GAP-43 expression increased in hippocampal CA1 and cortical region.Conclusion: SQTS showed therapeutic benefits on sequelae post-stroke in rats, which might be through the pathway of regeneration or neuroplasticity.

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.

目的考察参苓薏苡三七方联合止血生肌汤灌肠对脾虚湿热证溃疡性结肠炎患者的临床疗效。方法114例患者随机分为对照组和观察组,每组57例,对照组给予止血生肌汤灌肠,观察组在对照组基础上加用参苓薏苡三七方,疗程4周。检测临床疗效、中医证候评分、Baron内镜评分、改良Mayo评分、VAS评分、肠道菌群(肠球菌、乳酸杆菌、肠杆菌、双歧杆菌)、相关因子(FCP、ESR、IL-10、TNF-α、TLR4、PGE2)、肠道屏障功能因子(L/M、DAO、D-乳酸)、安全性指标变化。结果观察组完全缓解率、总有效率高于对照组(P<0.05)。治疗后,2组中医证候评分、Baron内镜评分、改良Mayo评分、VAS评分、FCP、ESR、TNF-α、TLR4、PGE2、肠道屏障功能因子降低(P<0.05),IL-10升高(P<0.05),肠球菌、肠杆菌减少(P<0.05),乳酸杆菌、双歧杆菌增加(P<0.05),以观察组更明显(肠球菌除外)(P<0.05)。2组均未见明显不良反应。结论参苓薏苡三七方联合止血生肌汤灌肠可安全有效地调节脾虚湿热证溃疡性结肠炎患者肠道菌群,改善肠道屏障功能,提高镇痛、消炎效果。

基于激光诱导击穿光谱技术的三七产地及道地研究

目的从元素角度出发,采用激光诱导击穿光谱(laser-induced breakdown spectroscopy,LIBS)结合化学计量学方法研究三七的道地性及产地鉴别。方法采集云南文山三七和曲靖三七的LIBS光谱数据,进行数据归一化处理,利用偏最小二乘判别分析(PLS-DA)方法判别三七产地,并采用VIP值筛选出对产地判别模型的贡献大的元素。结果基于LIBS技术和PLS-DA方法可以有效地进行云南文山三七和曲靖三七的产地判别。以450~840 nm全光谱为输入变量,PLS-DA判别模型训练集的敏感性、特异性和总判正率均为100%,预测集敏感性、特异性和总判正率分别为90.9%、90%和95%;以VIP值筛选的特征变量作为输入变量,PLS-DA判别分析模型的性能良好,训练集和预测集的敏感性、特异性和总判正率均为100%。表明VIP值筛选的特征变量可代表三七的产地信息。贡献度较大的元素分别为:Si、Mg、Ca、Na、K等。结论LIBS技术结合多变量分析方法能够快速实现云南文山三七和曲靖三七的道地性研究。所建立的方法具有分析快速、近似无损、样品前处理简单等特点,为中药产地和道地性研究提供新思路。
