Methods: Ninety-six SD rats were randomly divided into four groups: sham operation (saline 20 ml/kg), shock model (lipopolysaccharide, LPS, 8 mg/kg), Reformed Shengmai Yin (加味生脉饮 Pulse-activating Decoction) (LPS 8 mg/kg + reformed Shengmai Yin Injection 10 ml/kg), and dexamethasone (LPS 8 mg/kg + dexamethasone 5 mg/kg) groups. Each group was subdivided into 1 h, 2 h, 3 h, and 6 h time points for observation. The carotid artery was separated and connected with a biological functional system to monitor mean arterial pressure (MAP). Brain water levels, malonaldehyde (MDA) content, and superoxide dismutase (SOD) activity were also determined. Results: In the shock model group, MAP was progressively decreased after injection of LPS, brain water and MDA contents were increased, brain SOD activity was decreased, and capillary vessel edema in brain tissue was also observed. All these parameters were improved significantly in both treatment groups, although the effects were more marked with Shengmai Yin than with dexamethasone. Conclusion: Modified Shengmai Yin exhibits strong anti-shock and neuroprotective effects against Endotoxininduced shock.展开更多

METHODS: Randomized 70 Sprague-Dawley rats into sham(n = 10) and operation(n = 60) groups, then established the HF rat by ligating the left anterior descending branch of the coronary artery. We randomly divided the operation group rats into the model, ONSMP [including low(L), medium(M), and high(H) dose], and enalapril groups. After the 4-week drug intervention, echocardiography examines the cardiac function and calculates the ratios of the whole/left heart to the rat's body weight. Finally, we observed the degree of myocardial fibrosis by pathological sections, determined myocardium collagen(COL) Ⅰ and COL Ⅲ content by enzyme-linked immunosorbent assay, detected the m RNA levels of COL Ⅰ, COL Ⅲ, α-smooth muscle actin(α-SMA), and c-Fos proto-oncogene(c-Fos) by universal real-time, and detected the protein expression of p-RAS, p-RAF, p-MEK1/2, p-ERK1/2, p-ETS-like-1 transcription factor(p-ELK1), p-c-Fos, α-SMA, COL Ⅰ, and COL Ⅲ by Western blot. RESULTS: ONSMP can effectively improve HF rat's cardiac function, decrease cardiac organ coefficient, COL volume fraction, and COL Ⅰ/Ⅲ content, down-regulate the m RNA of COL Ⅰ/Ⅲ, α-SMA and c-Fos, and the protein of p-RAS, p-RAF, p-MEK1/2, p-ERK1/2, p-ELK1, c-Fos, COL Ⅰ/Ⅲ, and α-SMA. CONCLUSIONS: ONSMP can effectively reduce myocardial fibrosis in HF rats, and the mechanism may be related to the inhibition of the RAS/RAF/MEK/ERK signaling pathway.展开更多

Methods: One hundred and twenty-four patients with acute viral myocarditis were randomized into the treated group (SMG, n = 64) and the control group(CG, n = 60 ). Such myo-cardial nutrient medicine as ATP, CoA , Vit-C, were given to both groups. And to the treated group, 40 ml of Shengmai Injection per day was given intravenously for 2 weeks, which was followed by oral intake of Shengmai granule, one package three times daily for another 2 weeks in total. The same anti-arrhythmia agents were applied to both groups, and no fructose-1, 6-diphosphate (FDP) for either. Semi-quantitative scoring method was adopted to observe such symptoms as chest stuffiness, palpitation and chest pain before treatment and four weeks after treatment. Meanwhile, EGG, dynamic ECG by Holter monitor, left ventricular end-diastolic dimension (LVEDD), left ventricular ejection fraction (LVEF), serum neutralizing antibody of virus Coxsackie B, cardiac troponin I (cTnl) and cardiac troponin T (cTnT) were examined. Results: (1) Compared with the control group, more significant improvement was got in SMG in respects of chest stuffiness, palpitation, chest pain and arrhythmia (P<0.05 or P<0.01). (2) Negative converting rates of cTnl ,cTnT in the two groups were 59.46% vs35.48%, 68.75% vs42.31% respectively ( P<0. 05). (3) LVEDD before and after treatment in SMG was 52. 44 ± 3. 40 mm and 48. 81 ± 2. 23mm respectively, while that in the control group was 52. 31 ± 3. 74 mm and 49. 92 ± 2. 67mm respectively; LVEF before and after treatment in SMG was 60.67 ± 4. 62 % and 65. 02 ± 4. 16 % respectively, while that in the control group was 60.91 ± 4. 26 % and 63. 67 ± 3.17 % . There was obvious improvement in the two parameters in both groups, but the improvement in SMG was superior to that in the control group ( P<0. 05). Conclusion: SMP shows a good effect in improving clinical symptoms and signs, heart function, abnormal ECG and inflammatory injury indexes in patients with acute viral myocarditis.展开更多

Shengmai is an herbal medicine being used in treatments of cardiovascular diseases. However, effects of Shengmai on human blood vessels and related pharmacological mechanisms are unclear. Methods—This study investigated the effects of related mechanisms of Shengmai and its key compounds on human and sheep umbilical arteries and veins using organ bath systems. Key Findings—Shengmai significantly suppressed phenylephrine-stimulated vasoconstriction in umbilical arteries and veins. NG-Nitro-L-arginine Methyl Estercould not change the Shengmai-suppressed vasoconstriction in human and sheep umbilical vessels. Among four key compounds of Shengmai, Ginsenoside Re, Ginsenoside Rb1, Ginsenoside Rg1, and Schisandrin, only Ginsenoside Re showed the significant effect similar to Shengmai’s in the umbilical vessels. In Ca2+-free solution, Ginsenoside Re did not affect vasoconstriction. In addition, caffeine- or phenylephrine-stimulated vasoconstriction were not changed by Ginsenoside Re. Either charybdotoxin or glibenclamide could inhibit Ginsenoside Re-caused inhibition of the stimulated vasoconstriction in both human and sheep umbilical vessels, where 4-aminopyridine did not show the similar inhibitory effect. Conclusion—The results provide new information on Shengmai’s effects and underlying mechanisms in umbilical vessels. Importantly, the information gained offers interesting potential for developing new drugs acting on umbilical cords for fetal medicine.展开更多

Methods： Ninety ACS patients were randomized into two groups, the control group treated with conventional therapy and the SMI group treated with SMI. The patients＇ cardiac function was noted and the content of high sensitive C-reactive protein （hs-CRP） in venous blood was measured before treatment and 1 week and 3 weeks after treatment, so as to observe and compare their changes between the two groups. Results： The cardiac output, stroke volume and ejection fraction in the SMI group after 3 weeks of treatment were all higher than those in the control group （P〈0.05）. The serum content of hs-CRP was reduced in both groups （P〈0.05）, but the reduction in the SMI group was more significant than that in the control group （P〈0.05）. Conclusion： SMI could improve the cardiac function and further inhibit the inflammatory reaction in patients with ACS.展开更多

文摘Shengmai Yin(SMY)is a Chinese herbal decoction that effectively alleviates the side effects of radiotherapy in various cancers and helps achieve radiotherapy’s clinical efficacy.In this study,we explored the interaction mechanism among SMY,DNA methylation,and nasopharyngeal carcinoma(NPC).We identified differences in DNA methylation levels in NPC CNE-2 cells and its radioresistant cells(CNE-2R)using the methylated DNA immunoprecipitation array and found that CNE-2R cells showed genomewide changes in methylation status towards a state of hypomethylation.SMY may restore its original DNA methylation status,and thus,enhance radiosensitivity.Furthermore,we confirmed that the differential gene Tenascin-C(TNC)was overexpressed in CNE-2R cells and that SMY downregulated TNC expression.This downregulation of TNC inhibited NPC cell radiation resistance,migration,and invasion.Furthermore,we found that TNC was hypomethylated in CNE-2R cells and partially restored to a hypermethylated state after SMY intervention.DNA methyltransferases 3 a may be the key protein in DNA methylation of TNC.

文摘Objective:To examine the effects of modified Shenmai Yin on invigorating vital energy, promoting blood flow, and protection against neural impairment in an endotoxin-induced shock rat model. Methods: Ninety-six SD rats were randomly divided into four groups: sham operation (saline 20 ml/kg), shock model (lipopolysaccharide, LPS, 8 mg/kg), Reformed Shengmai Yin (加味生脉饮 Pulse-activating Decoction) (LPS 8 mg/kg + reformed Shengmai Yin Injection 10 ml/kg), and dexamethasone (LPS 8 mg/kg + dexamethasone 5 mg/kg) groups. Each group was subdivided into 1 h, 2 h, 3 h, and 6 h time points for observation. The carotid artery was separated and connected with a biological functional system to monitor mean arterial pressure (MAP). Brain water levels, malonaldehyde (MDA) content, and superoxide dismutase (SOD) activity were also determined. Results: In the shock model group, MAP was progressively decreased after injection of LPS, brain water and MDA contents were increased, brain SOD activity was decreased, and capillary vessel edema in brain tissue was also observed. All these parameters were improved significantly in both treatment groups, although the effects were more marked with Shengmai Yin than with dexamethasone. Conclusion: Modified Shengmai Yin exhibits strong anti-shock and neuroprotective effects against Endotoxininduced shock.

文摘Emerging research suggests a potential association of progression of Alzheimer's disease(AD)with alterations in synaptic currents and mitochondrial dynamics.However,the specific associations between these pathological changes remain unclear.In this study,we utilized Aβ42-induced AD rats and primary neural cells as in vivo and in vitro models.The investigations included behavioural tests,brain magnetic resonance imaging(MRI),liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)analysis,Nissl staining,thioflavin-S staining,enzyme-linked immunosorbent assay,Golgi-Cox staining,transmission electron microscopy(TEM),immunofluorescence staining,proteomics,adenosine triphosphate(ATP)detection,mitochondrial membrane potential(MMP)and reactive oxygen species(ROS)assessment,mitochondrial morphology analysis,electrophysiological studies,Western blotting,and molecular docking.The results revealed changes in synaptic currents,mitophagy,and mitochondrial dynamics in the AD models.Remarkably,intervention with Dengzhan Shengmai(DZSM)capsules emerged as a pivotal element in this investigation.Aβ42-induced synaptic dysfunction was significantly mitigated by DZSM intervention,which notably amplified the frequency and amplitude of synaptic transmission.The cognitive impairment observed in AD rats was ameliorated and accompanied by robust protection against structural damage in key brain regions,including the hippocampal CA3,primary cingular cortex,prelimbic system,and dysgranular insular cortex.DZSM intervention led to increased IDE levels,augmented long-term potential(LTP)amplitude,and enhanced dendritic spine density and length.Moreover,DZSM intervention led to favourable changes in mitochondrial parameters,including ROS expression,MMP and ATP contents,and mitochondrial morphology.In conclusion,our findings delved into the realm of altered synaptic currents,mitophagy,and mitochondrial dynamics in AD,concurrently highlighting the therapeutic potential of DZSM intervention.

文摘OBJECTIVE: Exploring the effect of Optimized New Shengmai powder(优化新生脉散方, ONSMP) on myocardial fibrosis in heart failure(HF) based on rat sarcoma(RAS)/rapidly accelerated fibrosarcoma(RAF)/mitogen-activated protein kinase kinase(MEK)/extracellular regulated protein kinases(ERK) signaling pathway. METHODS: Randomized 70 Sprague-Dawley rats into sham(n = 10) and operation(n = 60) groups, then established the HF rat by ligating the left anterior descending branch of the coronary artery. We randomly divided the operation group rats into the model, ONSMP [including low(L), medium(M), and high(H) dose], and enalapril groups. After the 4-week drug intervention, echocardiography examines the cardiac function and calculates the ratios of the whole/left heart to the rat's body weight. Finally, we observed the degree of myocardial fibrosis by pathological sections, determined myocardium collagen(COL) Ⅰ and COL Ⅲ content by enzyme-linked immunosorbent assay, detected the m RNA levels of COL Ⅰ, COL Ⅲ, α-smooth muscle actin(α-SMA), and c-Fos proto-oncogene(c-Fos) by universal real-time, and detected the protein expression of p-RAS, p-RAF, p-MEK1/2, p-ERK1/2, p-ETS-like-1 transcription factor(p-ELK1), p-c-Fos, α-SMA, COL Ⅰ, and COL Ⅲ by Western blot. RESULTS: ONSMP can effectively improve HF rat's cardiac function, decrease cardiac organ coefficient, COL volume fraction, and COL Ⅰ/Ⅲ content, down-regulate the m RNA of COL Ⅰ/Ⅲ, α-SMA and c-Fos, and the protein of p-RAS, p-RAF, p-MEK1/2, p-ERK1/2, p-ELK1, c-Fos, COL Ⅰ/Ⅲ, and α-SMA. CONCLUSIONS: ONSMP can effectively reduce myocardial fibrosis in HF rats, and the mechanism may be related to the inhibition of the RAS/RAF/MEK/ERK signaling pathway.

文摘Objective: To evaluate the clinical efficacy of Shengmai Powder (SMP, 生脉散) in treating a-cute viral myocarditis objectively. Methods: One hundred and twenty-four patients with acute viral myocarditis were randomized into the treated group (SMG, n = 64) and the control group(CG, n = 60 ). Such myo-cardial nutrient medicine as ATP, CoA , Vit-C, were given to both groups. And to the treated group, 40 ml of Shengmai Injection per day was given intravenously for 2 weeks, which was followed by oral intake of Shengmai granule, one package three times daily for another 2 weeks in total. The same anti-arrhythmia agents were applied to both groups, and no fructose-1, 6-diphosphate (FDP) for either. Semi-quantitative scoring method was adopted to observe such symptoms as chest stuffiness, palpitation and chest pain before treatment and four weeks after treatment. Meanwhile, EGG, dynamic ECG by Holter monitor, left ventricular end-diastolic dimension (LVEDD), left ventricular ejection fraction (LVEF), serum neutralizing antibody of virus Coxsackie B, cardiac troponin I (cTnl) and cardiac troponin T (cTnT) were examined. Results: (1) Compared with the control group, more significant improvement was got in SMG in respects of chest stuffiness, palpitation, chest pain and arrhythmia (P<0.05 or P<0.01). (2) Negative converting rates of cTnl ,cTnT in the two groups were 59.46% vs35.48%, 68.75% vs42.31% respectively ( P<0. 05). (3) LVEDD before and after treatment in SMG was 52. 44 ± 3. 40 mm and 48. 81 ± 2. 23mm respectively, while that in the control group was 52. 31 ± 3. 74 mm and 49. 92 ± 2. 67mm respectively; LVEF before and after treatment in SMG was 60.67 ± 4. 62 % and 65. 02 ± 4. 16 % respectively, while that in the control group was 60.91 ± 4. 26 % and 63. 67 ± 3.17 % . There was obvious improvement in the two parameters in both groups, but the improvement in SMG was superior to that in the control group ( P<0. 05). Conclusion: SMP shows a good effect in improving clinical symptoms and signs, heart function, abnormal ECG and inflammatory injury indexes in patients with acute viral myocarditis.
文摘Objective—The umbilical cord is a critical pathway between mothers and fetuses, and regulations of umbilical vessel tension are important for fetal growth. Shengmai is an herbal medicine being used in treatments of cardiovascular diseases. However, effects of Shengmai on human blood vessels and related pharmacological mechanisms are unclear. Methods—This study investigated the effects of related mechanisms of Shengmai and its key compounds on human and sheep umbilical arteries and veins using organ bath systems. Key Findings—Shengmai significantly suppressed phenylephrine-stimulated vasoconstriction in umbilical arteries and veins. NG-Nitro-L-arginine Methyl Estercould not change the Shengmai-suppressed vasoconstriction in human and sheep umbilical vessels. Among four key compounds of Shengmai, Ginsenoside Re, Ginsenoside Rb1, Ginsenoside Rg1, and Schisandrin, only Ginsenoside Re showed the significant effect similar to Shengmai’s in the umbilical vessels. In Ca2+-free solution, Ginsenoside Re did not affect vasoconstriction. In addition, caffeine- or phenylephrine-stimulated vasoconstriction were not changed by Ginsenoside Re. Either charybdotoxin or glibenclamide could inhibit Ginsenoside Re-caused inhibition of the stimulated vasoconstriction in both human and sheep umbilical vessels, where 4-aminopyridine did not show the similar inhibitory effect. Conclusion—The results provide new information on Shengmai’s effects and underlying mechanisms in umbilical vessels. Importantly, the information gained offers interesting potential for developing new drugs acting on umbilical cords for fetal medicine.

文摘Background:High altitude shock is attributed to myocardial ischemia and hypoxia.Jiuwei Shengmai powder has positive impacts on human physiology.However,it is unknown if it can mitigate myocardial ischemia and hypoxia.This study aimed to postulate the molecular mechanism that relieves myocardial hypoxia injury in officers and soldiers at high altitude after ingesting Jiuwei Shengmai powder by using network pharmacology and molecular docking.Methods:The effective components and potential targets of Jiuwei Shengmai powder were detected by databases such as the traditional Chinese medicine systems pharmacology(TCMSP),PubChem,and UniProt.Target genes related to myocardial hypoxia injury were identified using Gene Cards,Online Mendelian Inheritance in Man,DrugBank,DisGeNET,the Comparative Toxicogenomics Database,and other databases.CytoScape was used to construct a“drug-active ingredient-target gene”network.Protein-protein interactions(PPIs)were predicted using the STRING database.Core gene target data were analyzed using Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment utilizing R packages,while Autodock Vina was used to verify the molecular docking simulation.Results:One hundred and sixteen active ingredients were identified in Jiuwei Shengmai powder and were shown to target 197 genes.Of these,3073 core target genes were related to myocardial hypoxia injury,and 130 core genes were obtained after Veen intersection.There were 129 PPI nodes and 1769 edges.The docking binding energy was≤-5.0 kcal·mol-1,indicating strong binding between the active compounds and targets.Quercetin and kaempferol are the main components in Jiuwei Shengmai powder that relieve myocardial hypoxia injury.Their core targets are interleukin-6 and activated cysteine proteinase-3 antibody,which are mainly related to PI3K-Akt-,mitogen-activated protein kinase(MAPK),tumor necrosis factor(TNF),and interleukin 17(IL-17)signaling pathways.
文摘Objective： To confirm the effect of Shengmai Injection （生脉注射液, SMI） in improving cardiac function in patients with acute coronary syndrome （ACS） and to explore its influence on inflammatory reaction in patients. Methods： Ninety ACS patients were randomized into two groups, the control group treated with conventional therapy and the SMI group treated with SMI. The patients＇ cardiac function was noted and the content of high sensitive C-reactive protein （hs-CRP） in venous blood was measured before treatment and 1 week and 3 weeks after treatment, so as to observe and compare their changes between the two groups. Results： The cardiac output, stroke volume and ejection fraction in the SMI group after 3 weeks of treatment were all higher than those in the control group （P〈0.05）. The serum content of hs-CRP was reduced in both groups （P〈0.05）, but the reduction in the SMI group was more significant than that in the control group （P〈0.05）. Conclusion： SMI could improve the cardiac function and further inhibit the inflammatory reaction in patients with ACS.
