The patients received conventional therapy （antiplatelet drugs and hypolipidemic drugs） alone or conventional therapy plus 450 mg Xueshuantong once a day. The main ingredient of the Xueshuantong lyophilized powder used for injection was Panax notoginseng saponins. Assessments were made at admission and at discharge using the National Institutes of Health Stroke Scale, the Activity of Daily Living and the Mini-Mental State Examination. Additionally, the relative cerebral blood flow, relative cerebral blood volume and relative mean transit time in the region of interest were calculated within 24 hours after the onset of lacunar infarction, using dynamic susceptibility contrast magnetic resonance perfusion imaging technology. Patients underwent a follow-up MRI scan after 4 weeks of treatment. There was an improvement in the Activity of Daily Living scores and a greater reduction in the scores on the National Institutes of Health Stroke Scale in the treatment group than in the control group. However, the Mini-Mental State Examination scores showed no significant differences after 4 weeks of treatment. Compared with the control group, the relative cerebral blood flow at discharge had increased and showed a greater improvement in the treatment group. Furthermore, there was a reduction in the relative mean transit time at discharge and the value was lower in the treatment group than in the control group. The experimental findings indicate that Xueshuantong treatment improves neurological deficits in elderly patients with lacunar infarction, and the mechanism may be related to increased cerebral perfusion.展开更多

Methods: Fifty ACI patients were randomly divided into 2 groups, and XST group (30 patients) was treated with XST, and the control group (20 patients) given low molecular dextrose, as well as low molecular heparin calcium. The course of treatment for both groups was 15 days. The changes of effective rate, score of neurologic impairment, tissue-type plasminogen activator (tPA), inhibitor of plasminogen activator (PAI), D-D dimmer, antithrombin-III (AT-III), and fibrinogen (Fbg) were all observed. Results: The total effective rate of XST group was 73.33%, that of the control group 65. 00%. After the therapy, plasma level of tPA, ratio of tPA/PAI, and AT-III content were increased obviously, while the plasma level of PAI and D-D dimmer were decreased significantly (all P<0.01) . But there was only insignificant difference between the 2 groups (P> 0.05).Conclusion: XST injection could be effective to ACI, the mechanism of which is probably related to improving the balance between plasminogen activator and its inhibitory factor, increasing the activity of fi-brinolysin, inactivating thrombin, inhibiting platelet aggregation induced by thrombin, and decreasing blood coagulation.展开更多

Salvianolate Lyophilized Injection （SLI） and Xueshuantong Injection （Lyophilized） （XST）, which have been widely used in the treatment of acutely cerebral infarction clinically in China, exhibit various biological activities. In this study, the neuroprotective properties of SLI combined with XST in a rat model of middle cerebral artery occlusion- reperfusion （MCAO/R） were investigated. Methods： In this study, male Wistar rats were subjected to 1.5h of middle cerebral artery occlusion followed by reperfusion for 24 h. The rats were randomly divided into the following six groups： normal group （NOR）, model group （MOD）, SLI group （21 mg/kg, SLI）, ）（ST group （100 mg/kg, ）（ST）, SLI combined with XST （XST 100 mg/kg ＋ SLI 21 mg/kg, 1X1S）, and Edaravone （as a positive control drug, 6 mL/kg, EDI）, once a day for 3 d. The neuronal injury, the expression of glial fibrillary acidic protein （GFAP） and ionized calcium binding adaptor molecule 1 （IBA-1）, and the changes of pro-inflammatory mediators interleukin- 6 （IL-6）, tumor necrosis factor alpha （TNF-α） and anti-inflammatory mediator interleukin-10 （IL-10） were observed. Results： 1X1S treatment significantly increased the number of neuron, compared with the MOD group, SH group and XST group. Gliosis （GFAP and IBA-1） and expression of pro-inflammatory mediators IL-6 and TNF-a were significantly reduced. Meanwhile, 1XIS significantly increased the expression of anti- inflammatory mediator IL-10 in the brains of MCAO/R rats, compared with the MOD group, SLI and XST groups. SLI and XST also remarkably down-regulated the expression of IL-6 and TNF-α compared with the MOD group. Conclusions： This study shows that SLI combined with XST （1X1S） can protect cerebral ischemia- reperfusion injury due to its anti-inflammatory property, and may provide a potential promising new therapeutic strategy for acute ischemic stroke.展开更多

Methods Liquid chromatography coupled with electrospray ionization tandem mass spectrometry （LC-ESI-MSn） was used to profile the saponins in XST and P. notoginseng. Structural elucidation was based on spectral analyses of negative and positive ESI-MS3 data, and the comparison of the retention behaviors. Results The optimized LC-MS profiling approach enabled resolution of major saponins. The negative mode ESI-MS3 fragmentation gave diagnostic information on the nature （neutral loss 162 Da for GIc, 146 Da for Rha, and 132 Da for a pentose） and sequence （priority： terminal 〉 inner） of sugars and sapogenins （m/z 475 for protopanaxatriol; re^z459 for protopanaxadiol）, while the intact glycosyl portion could be characterized by characteristic Zoα, Cnnα＋, and Cnβ＋ （n = 2 or 3） obtained in the positive mode. Ultimately, a total of 30 saponins were characterized from XST. Compared with the roots of P. notoginseng, three malonyl-ginsenosides, ginsenoside Rd, and gyponoside XVII （or its isomer） were almost undetectable, and showed potential significance for their differentiation. Conclusion The established LC-MS profiling approach is powerful for the chemical analysis of P. notoginseng and its preparations such as XST.展开更多

文摘A total of 64 patients with acute lacunar infarction were enrolled within 24 hours of onset. The patients received conventional therapy （antiplatelet drugs and hypolipidemic drugs） alone or conventional therapy plus 450 mg Xueshuantong once a day. The main ingredient of the Xueshuantong lyophilized powder used for injection was Panax notoginseng saponins. Assessments were made at admission and at discharge using the National Institutes of Health Stroke Scale, the Activity of Daily Living and the Mini-Mental State Examination. Additionally, the relative cerebral blood flow, relative cerebral blood volume and relative mean transit time in the region of interest were calculated within 24 hours after the onset of lacunar infarction, using dynamic susceptibility contrast magnetic resonance perfusion imaging technology. Patients underwent a follow-up MRI scan after 4 weeks of treatment. There was an improvement in the Activity of Daily Living scores and a greater reduction in the scores on the National Institutes of Health Stroke Scale in the treatment group than in the control group. However, the Mini-Mental State Examination scores showed no significant differences after 4 weeks of treatment. Compared with the control group, the relative cerebral blood flow at discharge had increased and showed a greater improvement in the treatment group. Furthermore, there was a reduction in the relative mean transit time at discharge and the value was lower in the treatment group than in the control group. The experimental findings indicate that Xueshuantong treatment improves neurological deficits in elderly patients with lacunar infarction, and the mechanism may be related to increased cerebral perfusion.
文摘Objective: To observe the effect of Xueshuantong injection (XST,血栓通注射液) with its ingredient as Notoginseng saponin, on acute cerebral infarction (ACI) and on blood coagulation and fibri-nolysis, so as to comprehensively analyse the mechanism of XST. Methods: Fifty ACI patients were randomly divided into 2 groups, and XST group (30 patients) was treated with XST, and the control group (20 patients) given low molecular dextrose, as well as low molecular heparin calcium. The course of treatment for both groups was 15 days. The changes of effective rate, score of neurologic impairment, tissue-type plasminogen activator (tPA), inhibitor of plasminogen activator (PAI), D-D dimmer, antithrombin-III (AT-III), and fibrinogen (Fbg) were all observed. Results: The total effective rate of XST group was 73.33%, that of the control group 65. 00%. After the therapy, plasma level of tPA, ratio of tPA/PAI, and AT-III content were increased obviously, while the plasma level of PAI and D-D dimmer were decreased significantly (all P<0.01) . But there was only insignificant difference between the 2 groups (P> 0.05).Conclusion: XST injection could be effective to ACI, the mechanism of which is probably related to improving the balance between plasminogen activator and its inhibitory factor, increasing the activity of fi-brinolysin, inactivating thrombin, inhibiting platelet aggregation induced by thrombin, and decreasing blood coagulation.

文摘Objective： Inflammatory reactions induced by microglia in the brain play an important part in the pathogenesis of focal cerebral ischemia/reperfusion （I/R） injury, resulting in neuronal death. Salvianolate Lyophilized Injection （SLI） and Xueshuantong Injection （Lyophilized） （XST）, which have been widely used in the treatment of acutely cerebral infarction clinically in China, exhibit various biological activities. In this study, the neuroprotective properties of SLI combined with XST in a rat model of middle cerebral artery occlusion- reperfusion （MCAO/R） were investigated. Methods： In this study, male Wistar rats were subjected to 1.5h of middle cerebral artery occlusion followed by reperfusion for 24 h. The rats were randomly divided into the following six groups： normal group （NOR）, model group （MOD）, SLI group （21 mg/kg, SLI）, ）（ST group （100 mg/kg, ）（ST）, SLI combined with XST （XST 100 mg/kg ＋ SLI 21 mg/kg, 1X1S）, and Edaravone （as a positive control drug, 6 mL/kg, EDI）, once a day for 3 d. The neuronal injury, the expression of glial fibrillary acidic protein （GFAP） and ionized calcium binding adaptor molecule 1 （IBA-1）, and the changes of pro-inflammatory mediators interleukin- 6 （IL-6）, tumor necrosis factor alpha （TNF-α） and anti-inflammatory mediator interleukin-10 （IL-10） were observed. Results： 1X1S treatment significantly increased the number of neuron, compared with the MOD group, SH group and XST group. Gliosis （GFAP and IBA-1） and expression of pro-inflammatory mediators IL-6 and TNF-a were significantly reduced. Meanwhile, 1XIS significantly increased the expression of anti- inflammatory mediator IL-10 in the brains of MCAO/R rats, compared with the MOD group, SLI and XST groups. SLI and XST also remarkably down-regulated the expression of IL-6 and TNF-α compared with the MOD group. Conclusions： This study shows that SLI combined with XST （1X1S） can protect cerebral ischemia- reperfusion injury due to its anti-inflammatory property, and may provide a potential promising new therapeutic strategy for acute ischemic stroke.

文摘Objective：To establish a retinal vein occlusion（RVO） animal model and observe the therapeutic effect of a Chinese herbal composition（Fufang Xueshuantong Capsule,复方血栓通胶囊,FXC） in ischemic retinal disease.Methods：Fifteen adult male Sprague-Dawley rats underwent laser photothrombosis to induce RVO on their right eyes and were subsequently randomized to receive FXC（the intervention group,n=7） or placebo treatment（the control group,n=8）.Fundus fluorescein angiography was performed after 2,4 and 8 weeks of treatment.Real-time reverse transcription-PCR was used to quantify the mRNA expression of vascular endothelial growth factor（VEGF） and stromal cell-derived factor-1（SDF-1）.The main outcomes were the mRNA copies of VEGF and SDF-1 and the counts of RVO signs.Results：Laser photothrombosis procedure induced typical lesions of RVO,including hemorrhage,leakage,retinal detachment,capillary non-perfusion,filling defect of retinal vessels,and lateral circulation/dilation of small vessels.The retinal lesions were associated with an increased expression of VEGF（P0.05）.No significant change of SDF-1 expression was noticed.Compared with the control group,the intervention group had numerically fewer RVO lesions at week 2（1.71±0.76 vs.3.50±1.51,t=-2.82,P0.05）.The benefit of intervention remained at weeks 4 and 8.Conclusions：A rat model of laser photothrombosis-induced RVO was established and an increase in the VEGF expression was observed in the retinal lesion.The FXC had therapeutic benefit in improving retinal lesions in the rat model of RVO.

文摘Objective To investigate the ameliorate effect and underlying mechanism of Xueshuantong for Injection(Lyophilized,注射用血栓通,XST)in streptozocin(STZ)-induced diabetic retinopathy(DR)rats.Methods Diabetes mellitus(DM)model was induced by intraperitoneal(i.p.)injection of STZ(60 mg/kg)in Sprague-Dawley rats.Diabetic rats were randomized into 3 groups(n=10)according to a random number table,including DM,XST50 and XST100 groups.XST treatment groups were daily i.p.injected with 50 or 100 mg/kg XST for 60 days,respectively.The control and DM groups were given i.p.injection with saline.Blood glucose level and body weight were recorded every week.Histological changes in the retina tissues were observed with hematoxylin-eosin staining.Apoptosis and inflammation related factors,including cleaved caspase-3,glial fifibrillary acidic protein(GFAP),tumor necrosis factor-α(TNF-α)and intercellular cell adhesion molecule-1(ICAM-1)were detected by Western blot or real-time polymerase chain reaction.Then,the levels of advanced glycation end product(AGE)and its receptor(RAGE)were investigated.Tight junctions proteins(Zonula occludens-1(ZO-1),Occludin and Claudin-5)of blood-retinal barrier were detected by Western blot.The levels of retinal fifibrosis,transforming growth factor-β1(TGF-β1)-Smad2/3 signaling pathway were evaluated at last.Results There was no signifificant difference in the body weight and blood glucose level between XST and DM groups(P>0.05).Compared with the DM group,XST treatment signifificantly increased the retinal thickness of rats(P<0.05 or P<0.01),and suppressed cleaved caspase-3 expression(P<0.01).XST increased the protein expressions of ZO-1,Occludin and Claudin-5 and decreased the mRNA expressions of matrix metalloproteinase 2(MMP-2)and MMP-9(P<0.05 or P<0.01).Moreover,XST signifificantly reduced the productions of AGE and RAGE proteins in the retina of rats(P<0.05 or P<0.01),suppressed the over-expression of TNF-α,and decreased the elevated level of ICAM-1 in retina of rats(P<0.05 or P<0.01).XST signifificantly reduced the levels ofα-smooth muscle actin(α-SMA),connective tissue growth factor(CTGF),TGF-β1 and phosphorylation of Smad2/3 protein in rats(P<0.05 or P<0.01).Conclusions XST had protective effects on DR with possible mechanisms of inhibiting the inflammation and apoptosis,up-regulating the expression of tight junction proteins,suppressing the productions of AGE and RAGE proteins,and blocking the TGF-β/Smad2/3 signaling pathway.XST treatment might play a role for the future therapeutic strategy against DR.

文摘Objective To elucidate the chemical components of Xueshuantong （XST） Lyophilized Powder and primarily disclose the chemical difference between XST and Panax notoginseng roots. Methods Liquid chromatography coupled with electrospray ionization tandem mass spectrometry （LC-ESI-MSn） was used to profile the saponins in XST and P. notoginseng. Structural elucidation was based on spectral analyses of negative and positive ESI-MS3 data, and the comparison of the retention behaviors. Results The optimized LC-MS profiling approach enabled resolution of major saponins. The negative mode ESI-MS3 fragmentation gave diagnostic information on the nature （neutral loss 162 Da for GIc, 146 Da for Rha, and 132 Da for a pentose） and sequence （priority： terminal 〉 inner） of sugars and sapogenins （m/z 475 for protopanaxatriol; re^z459 for protopanaxadiol）, while the intact glycosyl portion could be characterized by characteristic Zoα, Cnnα＋, and Cnβ＋ （n = 2 or 3） obtained in the positive mode. Ultimately, a total of 30 saponins were characterized from XST. Compared with the roots of P. notoginseng, three malonyl-ginsenosides, ginsenoside Rd, and gyponoside XVII （or its isomer） were almost undetectable, and showed potential significance for their differentiation. Conclusion The established LC-MS profiling approach is powerful for the chemical analysis of P. notoginseng and its preparations such as XST.
