Buyang Huanwu decoction is a commonly used traditional Chinese medicine for the treatment of stroke. This paper summarizes the active components of the Chinese herb, which is composed of Huangqi (Radix Astragali seu Hedysari), Danggui (Radix Angelica sinensis), Chishao (Radix Paeoniae Rubra), Chuanxiong (Rhizoma Ligustici Chuanx- iong), Honghua (Flos Carthami), Taoren (Semen Persicae) and Dilong (Pheretima), and identifies the therapeutic targets and underlying mechanisms that contribute to the neuroprotective prop- erties of Buyang Huanwu decoction.展开更多

However, the exact mechanism underlying BYHWD's amelioration of ischaemic stroke and its effective constituents remain unclear. The present study aimed to identify the effective constituents of BYHWD and to further explore its action mechanisms in the amelioration of ischaemic stroke by testing the activities of 15 absorbable chemical constituents of BYHWD with the same methods under the same conditions. The following actions of these 15 compounds were revealed: 1) Ferulic acid, calycosin, formononetin, astrapterocarpan-3-O-β-D-glucoside, paeonol, calycosin-7-O-β-D-glucoside, astraisofla- van-7-O-β-D-glucoside, ligustrazine, and propyl gallate significantly suppressed concanavalin A (Con A)-induced T lymphocyte proliferation; 2) Propyl gallate, calycosin-7-O-β-D-glucoside, paeonol, and ferulic acid markedly inhibited LPS-induced apoptosis in RAW264.7 cells; 3) Propyl gallate and formononetin significantly inhibited LPS-induced NO release; 4) Hydroxysaffior yellow A and inosine protected PC12 cells against the injuries caused by glutamate; and 5) Formononetin, astragaloside IV, astraisofiavan-7-O-β-D- glucoside, inosine, paeoniflorin, ononin, paeonol, propyl gallate, ligustrazine, and ferulic acid significantly suppressed the constriction of the thoracic aorta induced by KCI in rats. In conclusion, the results from the present study suggest that BYHWD exerts its ischaemic stroke ameliorating activities by modulating multiple targets with multiple components.展开更多

This study aims to observe the cerebral angiogenesis effects of BYHWD on chronic brain injury after focal cerebral ischemia in rats and to explore its possible mechanisms. The ischemia was induced by occlusion of the right middle cerebral artery for 90 min. BYHWD (12.5 and 25.0 g/(kg.d), equivalent to the dry weight of the raw materials) was orally administered twice a day beginning 2 h after surgery. BYHWD significantly attenuated the neurological dysfunction, infarct volume, and brain atrophy after ischemia. There was a significant increase in the microvessel density, as assessed by immunofluorescence CD31, and a significant increase in angiopoietin-1 (Ang-1) in the pe- numbra areas of the rats was shown by immunohistochemical staining and Western blotting. The results indicate that the neurorestorative effects of BYHWD are associated with angiogenesis and the enhancement of the expressions of Ang-1 on chronic brain injury after focal cerebral ischemia.展开更多

However, the precise mechanisms underlying its effect remain poorly understood. In this study, we established a rat model of cerebral ischemia by middle cerebral artery occlusion and intragastrically administered 5 g/kg Buyang Huanwu Decoction, once per day, for 1, 7, 14 and 28 days after cerebral ischemia. Immunohistochemical staining revealed a number of cells positive for the neural stem cell marker nestin in the cerebral cortex, the subven- tricular zone and the ipsilateral hippocampal dentate gyrus in rat models of cerebral ischemia. Buyang Huanwu Decoction significantly increased the number of cells positive for 5-bromodeoxyuridine (BrdU), a cell proliferation-related marker, microtubule-associated protein-2, a marker of neuronal differentiation, and growth-associated protein 43, a marker of synaptic plasticity in the ischemic rat cerebral regions. The number of positive cells peaked at 14 and 28 days after intragastric administration of Buyang Huanwu Decoction. These findings suggest that Buyang Huanwu Decoction can promote the proliferation and differentiation of neural stem cells and en- hance synaptic plasticity in ischemic rat brain tissue.展开更多

Vascular endothelial growth factor (VEGF) has been considered a potential therapeutic target for stroke. Buyang Huanwu decoction (BYHWD) is a classic traditional formula in traditional Chinese medicine and is used to treat stroke; in addition, the promotion effects on VEGF protein expression have been confirmed. However, little is known about how BYHWD regulates angiogenesis, or about the effects of BYHWD on VEGF mRNA expression. For this reason, the present study measured microvessel density in rats with cerebral ischemia using immunohistochemistry. In addition, VEGF expression was measured by re-verse-transcription polymerase chain reaction and enzyme-linked immunosorbent assay to determine the effects of BYHWD on angiogenesis and VEGF expression in rats with cerebral ischemia. Results demonstrated that microvessel density, as well as VEGF mRNA and protein expression, increased after 7 and 14 days of BYHWD treatment, which suggests that BYHWD promoted angiogenesis following cerebral ischemia and upregulated VEGF mRNA and protein expression in ischemic cerebral regions.展开更多

Gerbils were pretreated with BYHWD, and then subjected to cerebral ischemia and reperfusion. Microvascular changes were determined with laser Doppler monitoring, tannic acid-ferric chloride mordant, and electron microscopy. Results showed that BYHWD pretreatment could enhance the function of hippocampal microvessels, prevent injury, and increase microvasular density and microvasular area density. Thus, these results suggest that BYHWD pretreatment could prevent microvascular occlusion, enhance the capacity of microvascular reperfusion, increase cerebral blood flow, and inhibit neuronal damage, and may be an effective therapy against brain ischemic injury.展开更多

The aim of this study was to demonstrate the neuroprotective effect and mechanism of Buyang Huanwu Decoction fraction on ischemic injury both in vivo and in vitro. In vivo experiments showed that 50-200 mg/kg Buyang Huanwu Decoction fraction reduced infarct volume and pathological injury in ischemia/reperfusion rats, markedly inhibited expression of nuclear factor-KB and tumor necrosis factor-a and promoted nestin protein expression in brain tissue. Buyang Huanwu Decoction fraction (200 mg/kg) exhibited significant effects, which were similar to those of 100 mg/kg Ginkgo biloba extract. In vitro experimental results demonstrated that 10-100 mg/L Buyang Huanwu Decoction fraction significantly improved cell viability, decreased the release of lactate dehydrogenase and malondialdehyde levels, and inhibited the rate of apoptosis in HT22 cells following oxygen-glucose deprivation. Buyang Huanwu Decoction fraction (100 mg/L) exhibited significant effects, which were similar to those of 100 mg/L Ginkgo biloba extract. These findings suggest that Buyang Huanwu Decoction fraction may represent a novel, protective strategy against cerebral ischemia/reperfusion injury in rats and oxygen-glucose deprivation-induced damage in HT22 cells in vitro by attenuating the inflammatory response and cellular apoptosis.展开更多

After 28 days, nestin and neuron-specific enolase were expressed in the cytoplasm. Reverse transcription-PCR and western blot analyses showed that nestin and neuron-specific enolase mRNA and protein expression was greater in the active principle region group compared with the original formula group. Results demonstrated that the active principle region of Buyang Huanwu decoction induced greater differentiation of rat bone marrow-derived mesenchymal stem cells into neural-like cells in vitro than the original Buyang Huanwu decoction formula.展开更多

Methods: Local cerebral ischemia-reperfusion rat model was established with modified Zea-Longa thread-occlusion method, and MSCs were injected into the caudal vein, and Buyang Huanwu Tang(补阳还五汤)was administrated. Vascular endothelial growth factor (VEGF) and Ki-67 expression in the ischemic side of the brain in the cerebral ischemic-reperfusion rat were detected with immuno-histochemical staining method. Results: VEGF and Ki-67 expressions were significantly up-regulated in the MSCs group and the combination group, with significant differences as compared with the model group and the sham operation group (P<0.05), and with the most strongest effect in the combination group. Conclusion: Buyang Huanwu Tang(补阳还五汤)combined with MSCs transplantation repairs the injured blood vessels and lesion tissues possibly by up-regulation of VEGF and Ki-67 expression.展开更多

Buyang Huanwu decoction (BHD) can effectively improve cerebral blood flow and protect against cerebral ischemia/reperfusion damage. OBJECTIVE: To study the effects of BHD on cell proliferation and differentiation in the hippocampal dentate gyrus of rats following cerebral infarction, to investigate the protective effects of BHD against cerebral infarction, and to analyze the dose-effect relationship. DESIGN, TIME AND SETTING: This randomized, controlled, animal study was performed at the Laboratory of Department of Physiology, Henan College of Traditional Chinese Medicine, China from June 2007 to February 2008. MATERIALS: A total of 36 male, Sprague Dawley rats, aged 20-21 months, were equally and randomly assigned to the following groups: sham operation, model control, and nimodipine, as well as high-dose, moderate-dose, and low-dose BHD. BHD was composed of milkvetch root, Chinese angelica, red peony root, earthworm, peach seed, safflower, and Szechwan Iovage rhizome, which were provided by the Outpatient Department, Henan College of Traditional Chinese Medicine, China. METHODS: The Chinese medicinal ingredients described above were decocted. The external carotid artery was ligated in rats from the sham operation group. Rat models of focal cerebral infarction were established by middle cerebral artery occlusion in the model control and nimodipine groups, as well as the high-dose, moderate-dose, and low-dose BHD groups. The drugs were administered by gavage 5 days, as well as 2 hours, prior to model induction. Rats in the nimodipine group were daily administered a 6 mg/kg nimodipine suspension by gavage. Rats in the high-dose, moderate-dose, and low-dose BHD groups were administered daily 26, 13, and 6.5 g/kg BHD, respectively. Rats in the sham operation and model control groups were treated with an equal volume of saline. MAIN OUTCOME MEASURES: The effects of BHD on neurological dysfunction score, brain water content, cell proliferation and differentiation in the hippocampal dentate gyrus, and pathological changes in the ischemic brain hemisphere were measured in cerebral infarction rats. RESULTS: Compared with the sham operation group, the neurological dysfunction score, brain water content, number of BrdU-positive cells, BrdU/NeuN-positive cells, and BrdU/GFAP-positive cells in the hippocampal dentate gyrus significantly increased in the model control group (P 〈 0.01 ). Compared with the model control group, neurological dysfunction score and brain water content were significantly decreased (P 〈 0.01 or 0.05), as were the number of BrdU-positive and BrdU/NeuN-positive cells (P 〈 0.01 or 0.05). The number of BrdU/GFAP-positive cells was significantly reduced (P 〈 0.05) in the nimodipine group, high-dose, moderate-dose, and low-dose BHD groups. Compared with the nimodipine group, the neurological dysfunction score was significantly reduced in the moderate-dose BHD group (P 〈 0.05). However, the number of BrdU-positive cells was significantly increased in the rat hippocampal dentate gyrus in the high-dose and moderate-dose BHD groups (P 〈 0.01 or 0.05). The following was determined by microscopy: slightly disarranged neural cells, mild vascular dilatation, inflammatory cell infiltration, and light tissue edema were observed in the nimodipine group; inflammatory celt infiltration was reduced in the low-dose BHD group; cerebral edema and inflammatory cell infiltration were significantly reduced in the high-dose and in the moderate-dose BHD group. Electron microscopy revealed lipofuscin, slightly swollen mitochondria, and normal rough endoplasmic reticulum in the high-dose and moderate-dose BHD groups. Improvement was best in the moderate-dose BHD group. CONCLUSION: Cerebral ischemia activated proliferation of neural stem cells in the rat hippocampal dentate gyrus. The actions of BHD against cerebral ischemia/reperfusion damage correlated with proliferation and differentiation of neural stem cells in the hippocampal dentate gyrus. A moderate-dose of BHD resulted in the most effective outcome.展开更多

METHOD: Following treatment of rats with BYHWD at 6.42, 12.83, or 25.66 g·kg–1 per day for 15 days, microsomes and cytosols isolated from the liver tissues were prepared by differential centrifugation according to standard procedures. The activities of the antioxidant enzymes and cytochrome b5, NADPH-cytochrome P450 reductase, CYP3 A, CYP2E1, UGT, and GST of the rat livers were determined by UV-Vis spectrophotometer. RESULTS: The activities of ALT, AST, antioxidant enzymes, and the Hepatosomatic Index in serum were not significantly affected. In cytosols, the activity of CAT was significantly increased at the dosage of 12.83 g·kg–1, and all the other antioxidant activities and MDA levels were not affected by this treatment. BYHWD had no effect on cytochrome b5, NADPH-cytochrome P450 reductase, CYP3 A, and UGT. At the highest dose(25.66 g·kg–1), the activity of CYP2E1 was significantly inhibited, and the activities of GST and the level of GSH were increased. CONCLUSION: BYHWD is safe for the liver, and has the functions of detoxification and antioxidant. Patients should be cautioned about the herb-drug interaction of BYHWD and CYP2E1 substrates.展开更多

METHODS: In this ...OBJECTIVE: To study the molecular mechanism of Buyang Huanwu Tang( 补阳还五汤)(BHT) protecting retinal ganglion cells(RGCs) from oxygen induced oxidative stress and apoptosis after anterior ischemia. METHODS: In this study, the Chinese herbs of BHT were extracted by first boiling in water, then were filtered, concentrated, and freeze-dried. The chemical profile of BHT extract was determined by liquid chromatography mass spectrometry(LC-MS). H2O2-induced RGC-5 cells were used as a cell model to investigate the protective effect and mechanism of BHT on RGCs. RESULTS: The survival rate of damaged RGC-5 by BHT was significantly increased by the 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazolium-romid method. Fluorescence activating cell sorter(FACS analysis) showed that BHT could significantly reduce apoptosis induced by oxidative stress via the reactive oxygen species(ROS)-mitogen-activated protein kinase(MAPK)-Caspase-3 signal pathway. CONCLUSION: BHT possesses a high antioxidant capacity and could significantly reduce ROS levels of RGC-5 cells damaged by H2O2.Therefore, the present study has provided possible alternative strategies for the prevention and treatment of ischemic optic disease by using traditional Chinese herbal formulas.展开更多

Compared with normal rats, nerve cell membrane fluidity significantly decreased in ischemia/reperfusion rats as detected by spin-labeling electron spin resonance, consistent with order parameter S and rotational correlation time TC measurements. Brain nerve cells from rats with ischemia/reperfusion injury were cultured with 1-100 mg/mL Buyang Huanwu decoction. Results showed that Buyang Huanwu decoction gradually increased membrane fluidity dose-dependently to normal levels, and eliminated hydroxide (OH') and superoxide (O2') free radicals dose-dependenUy. These findings suggest that Buyang Huanwu decoction can protect against cell membrane fluidity changes in rats with ischemia/ reperfusion injury by scavenging free radicals.展开更多

Mitogen-activated protein kinase signaling was identified as one of the key pathways underlying this differentiation process. The present study shows phosphorylated extracellular signal-regulated protein kinase and phosphorylated p38 protein expression was increased after differentiation. Cellular signaling pathway blocking agents, PD98059 and SB203580, inhibited extracellular signal-regulated protein kinase and p38 in mitogen-activated protein kinase signaling pathways respectively, mRNA and protein expression of the neuronal marker, neuron specific enolase, and neural stem cell marker, nestin, were decreased in bone marrow mesenchymal stem cells after treatment with the active principle region of Buyang Huanwu decoction. Experimental findings indicate that, extracellular signal-regulated protein kinase and p38 in mitogen-activated protein kinase signaling pathways participate in bone marrow mesenchymal stem cell differentiation into neuron-like cells, induced by the active principle region of Buyang Huanwu decoction.展开更多

Buyang Huanwu decoction, a traditional Chinese herbal preparation, can promote the growth of nerve cells and nerve fibers; however, it is unclear whether Buyang Huanwu decoction affects the Notch signaling pathway in injured spinal cord. In this study, a rat model was established by injuring the T10 spinal cord. At 2 days after injury, rats were intragastrically administered 2 m L of 0.8 g/m L Buyang Huanwu decoction daily until sacrifice. Real-time reverse transcription polymerase chain reaction analysis demonstrated that at 7, 14 and 28 days after injury, the expression of Notch1 was increased in the Buyang Huanwu decoction group compared with controls. These findings confirm that Buyang Huanwu decoction can promote the expression of Notch1 in rats with incomplete spinal cord injury, and may indicate a mechanism to promote the repair of spinal cord injury.展开更多

In order to reveal the compatibility mechanism of buyang huanwu decoction (BHD)'s prescription in treating and preventing ischemic cerebrovascular disease, we need to explore the effect and relation of ingredients in prescription except for considering the effect of each ingredient on the whole prescription. OBJECTIVE: To study the effect of BHD and its ingredients in the prescription on the specific binding of 3H-platelet activating factor (PAF) to its receptor (PAFR)in rabbits in vitro, and to analyze the action of each ingredient in the prescription. DESIGN: A decomposed recipe study based on orthogonal test. SETTING: Guangzhou University of Traditional Chinese Medicine. MATERIALS: Five healthy adult New Zealand rabbits of either gender were provided by the Experimental Animal Center of Guangzhou University of Traditional Chinese medicine. The prescription herbal pieces were purchased from Foshan Kangpu Pharmaceuticals Company and Jianmin Pharmaceuticals Company, and were appraised by Professor Yanchen Xu from College of Traditional Chinese Medicine, Guangzhou University of Traditional Chinese Medicine. 3H-PAF was supplied by Amersham Co,Ltd.(Specific activity: 6.475 TBq/mmol;batch number:200402); PAF standard by Biomol Co., Ltd.(batch number: P1318V). METHODS: This experiment was carried out in the Laboratory of Nuclear Medicine, Guangzhou University of Traditional Chinese Medicine between September and December 2004. ①The seven influencing factors were selected: such as Shenghuangqi , Dangguiwei, Chishao, Dilong, Taoren, Honghua, Chuanxiong. Each factor was divided into two levels, selected or not selected. The tests were arranged according to L8 (27) orthogonal test table. ②The specific binding of 3H-PAF to its receptors in rabbits was measured by radioligand binding assay. The inhibitory rate of the specific binding was used as an assessing index. The inhibitory action of and on 3H-PAF to PAFR binding was analyzed and compared in vitro. The inhibitory action of each ingredient in the prescription BHD on 3H-PAF to PAFR binding was investigated and compared in vitro by direct analysis and analysis of variance of orthogonal test. MAIN OUTCOME MEASURES: Effect of 8 prescriptions for L8 (27) orthogonal test table on the specific binding inhibition rate of 3H-PAF and PAFR. RESULTS: According to results of variance analysis of orthogonal test, the inhibitory action of each ingredient in the prescription BHD on 3H-PAF to PAFR binding from the highest to the lowest was in turn Honghua, ShenghuangqL Taoren, Dilong, DangguiweL Chuanxiong, Chishao. Honghua, Shenghuangqi, Taoren, Dilong, Danguiwei were major influence factors to 3H-PAF to PAFR in rabbits (F = 187.829,144.446,59.521,5.018,4.265, P 〈 0.05- 0.01), but Chuanxiong and Chishao had not obviously inhibitory effect. The specific binding inhibition rate of prescriptions (except Shenghuangqi ) was obviously higher than that of one of prescriptions (Shenghuangqi included). CONCLUSION: The results of orthogonal test show that Honghua, ShenghuangqL Taoren, Dilong, Dangguiwei are major influencing factors to inhibit binding of sH-PAF to PAFR in rabbits, among which, Honghua is the strongest in ingredients of prescription BHD. The results also reveal that Shenghuangqi is able to weaken the inhibitory effect and to prevent the strong inhibitory effect of blood-activating drugs in BHD.展开更多

文摘Buyang Huanwu Decoction (BYHWD) is a well-known traditional Chinese medicine prescription which is used to treat ischaemic stroke and stroke-induced disabilities. However, the exact mechanism underlying BYHWD's amelioration of ischaemic stroke and its effective constituents remain unclear. The present study aimed to identify the effective constituents of BYHWD and to further explore its action mechanisms in the amelioration of ischaemic stroke by testing the activities of 15 absorbable chemical constituents of BYHWD with the same methods under the same conditions. The following actions of these 15 compounds were revealed: 1) Ferulic acid, calycosin, formononetin, astrapterocarpan-3-O-β-D-glucoside, paeonol, calycosin-7-O-β-D-glucoside, astraisofla- van-7-O-β-D-glucoside, ligustrazine, and propyl gallate significantly suppressed concanavalin A (Con A)-induced T lymphocyte proliferation; 2) Propyl gallate, calycosin-7-O-β-D-glucoside, paeonol, and ferulic acid markedly inhibited LPS-induced apoptosis in RAW264.7 cells; 3) Propyl gallate and formononetin significantly inhibited LPS-induced NO release; 4) Hydroxysaffior yellow A and inosine protected PC12 cells against the injuries caused by glutamate; and 5) Formononetin, astragaloside IV, astraisofiavan-7-O-β-D- glucoside, inosine, paeoniflorin, ononin, paeonol, propyl gallate, ligustrazine, and ferulic acid significantly suppressed the constriction of the thoracic aorta induced by KCI in rats. In conclusion, the results from the present study suggest that BYHWD exerts its ischaemic stroke ameliorating activities by modulating multiple targets with multiple components.

文摘Buyang Huanwu decoction (BYHWD), a traditional Chinese herbal prescription, has been widely used clinically to treat stroke in China for hundreds of years; however, the mechanisms of this drug for stroke treatment are still unclear. This study aims to observe the cerebral angiogenesis effects of BYHWD on chronic brain injury after focal cerebral ischemia in rats and to explore its possible mechanisms. The ischemia was induced by occlusion of the right middle cerebral artery for 90 min. BYHWD (12.5 and 25.0 g/(kg.d), equivalent to the dry weight of the raw materials) was orally administered twice a day beginning 2 h after surgery. BYHWD significantly attenuated the neurological dysfunction, infarct volume, and brain atrophy after ischemia. There was a significant increase in the microvessel density, as assessed by immunofluorescence CD31, and a significant increase in angiopoietin-1 (Ang-1) in the pe- numbra areas of the rats was shown by immunohistochemical staining and Western blotting. The results indicate that the neurorestorative effects of BYHWD are associated with angiogenesis and the enhancement of the expressions of Ang-1 on chronic brain injury after focal cerebral ischemia.

文摘The traditional Chinese medicine Buyang Huanwu Decoction has been shown to improve the neu- rological function of patients with stroke. However, the precise mechanisms underlying its effect remain poorly understood. In this study, we established a rat model of cerebral ischemia by middle cerebral artery occlusion and intragastrically administered 5 g/kg Buyang Huanwu Decoction, once per day, for 1, 7, 14 and 28 days after cerebral ischemia. Immunohistochemical staining revealed a number of cells positive for the neural stem cell marker nestin in the cerebral cortex, the subven- tricular zone and the ipsilateral hippocampal dentate gyrus in rat models of cerebral ischemia. Buyang Huanwu Decoction significantly increased the number of cells positive for 5-bromodeoxyuridine (BrdU), a cell proliferation-related marker, microtubule-associated protein-2, a marker of neuronal differentiation, and growth-associated protein 43, a marker of synaptic plasticity in the ischemic rat cerebral regions. The number of positive cells peaked at 14 and 28 days after intragastric administration of Buyang Huanwu Decoction. These findings suggest that Buyang Huanwu Decoction can promote the proliferation and differentiation of neural stem cells and en- hance synaptic plasticity in ischemic rat brain tissue.

文摘Angiogenesis in the infarct periphery can improve blood flow. Vascular endothelial growth factor (VEGF) has been considered a potential therapeutic target for stroke. Buyang Huanwu decoction (BYHWD) is a classic traditional formula in traditional Chinese medicine and is used to treat stroke; in addition, the promotion effects on VEGF protein expression have been confirmed. However, little is known about how BYHWD regulates angiogenesis, or about the effects of BYHWD on VEGF mRNA expression. For this reason, the present study measured microvessel density in rats with cerebral ischemia using immunohistochemistry. In addition, VEGF expression was measured by re-verse-transcription polymerase chain reaction and enzyme-linked immunosorbent assay to determine the effects of BYHWD on angiogenesis and VEGF expression in rats with cerebral ischemia. Results demonstrated that microvessel density, as well as VEGF mRNA and protein expression, increased after 7 and 14 days of BYHWD treatment, which suggests that BYHWD promoted angiogenesis following cerebral ischemia and upregulated VEGF mRNA and protein expression in ischemic cerebral regions.

文摘Buyang Huanwu decoction (BYHWD) is a classic recipe for the prevention and treatment of ischemic cerebrovascular disease. Gerbils were pretreated with BYHWD, and then subjected to cerebral ischemia and reperfusion. Microvascular changes were determined with laser Doppler monitoring, tannic acid-ferric chloride mordant, and electron microscopy. Results showed that BYHWD pretreatment could enhance the function of hippocampal microvessels, prevent injury, and increase microvasular density and microvasular area density. Thus, these results suggest that BYHWD pretreatment could prevent microvascular occlusion, enhance the capacity of microvascular reperfusion, increase cerebral blood flow, and inhibit neuronal damage, and may be an effective therapy against brain ischemic injury.

文摘Buyang Huanwu Decoction fraction extracted from Buyang Huanwu Decoction contains saponins of Astragalus, total paeony glycoside and safflower flavones. The aim of this study was to demonstrate the neuroprotective effect and mechanism of Buyang Huanwu Decoction fraction on ischemic injury both in vivo and in vitro. In vivo experiments showed that 50-200 mg/kg Buyang Huanwu Decoction fraction reduced infarct volume and pathological injury in ischemia/reperfusion rats, markedly inhibited expression of nuclear factor-KB and tumor necrosis factor-a and promoted nestin protein expression in brain tissue. Buyang Huanwu Decoction fraction (200 mg/kg) exhibited significant effects, which were similar to those of 100 mg/kg Ginkgo biloba extract. In vitro experimental results demonstrated that 10-100 mg/L Buyang Huanwu Decoction fraction significantly improved cell viability, decreased the release of lactate dehydrogenase and malondialdehyde levels, and inhibited the rate of apoptosis in HT22 cells following oxygen-glucose deprivation. Buyang Huanwu Decoction fraction (100 mg/L) exhibited significant effects, which were similar to those of 100 mg/L Ginkgo biloba extract. These findings suggest that Buyang Huanwu Decoction fraction may represent a novel, protective strategy against cerebral ischemia/reperfusion injury in rats and oxygen-glucose deprivation-induced damage in HT22 cells in vitro by attenuating the inflammatory response and cellular apoptosis.

文摘The present study induced in vitro-cultured passage 4 bone marrow-derived mesenchymal stem cells to differentiate into neural-like cells with a mixture of alkaloid, polysaccharide, aglycone, glycoside, essential oils, and effective components of Buyang Huanwu decoction (active principle region of decoction for invigorating yang for recuperation). After 28 days, nestin and neuron-specific enolase were expressed in the cytoplasm. Reverse transcription-PCR and western blot analyses showed that nestin and neuron-specific enolase mRNA and protein expression was greater in the active principle region group compared with the original formula group. Results demonstrated that the active principle region of Buyang Huanwu decoction induced greater differentiation of rat bone marrow-derived mesenchymal stem cells into neural-like cells in vitro than the original Buyang Huanwu decoction formula.

文摘Objective:To explore the mechanism of Buyang Huanwu Tang (补阳还五汤 Decoction Invigorating Yang for Recuperation) combined with bone marrow mesenchymal stem cells (MSCs) transplantation in protecting nerves of cerebral ischemic injury. Methods: Local cerebral ischemia-reperfusion rat model was established with modified Zea-Longa thread-occlusion method, and MSCs were injected into the caudal vein, and Buyang Huanwu Tang(补阳还五汤)was administrated. Vascular endothelial growth factor (VEGF) and Ki-67 expression in the ischemic side of the brain in the cerebral ischemic-reperfusion rat were detected with immuno-histochemical staining method. Results: VEGF and Ki-67 expressions were significantly up-regulated in the MSCs group and the combination group, with significant differences as compared with the model group and the sham operation group (P<0.05), and with the most strongest effect in the combination group. Conclusion: Buyang Huanwu Tang(补阳还五汤)combined with MSCs transplantation repairs the injured blood vessels and lesion tissues possibly by up-regulation of VEGF and Ki-67 expression.
文摘BACKGROUND: The mobilization of endogenous stem cells is an effective way to promote repair following ischemic brain damage. Buyang Huanwu decoction (BHD) can effectively improve cerebral blood flow and protect against cerebral ischemia/reperfusion damage. OBJECTIVE: To study the effects of BHD on cell proliferation and differentiation in the hippocampal dentate gyrus of rats following cerebral infarction, to investigate the protective effects of BHD against cerebral infarction, and to analyze the dose-effect relationship. DESIGN, TIME AND SETTING: This randomized, controlled, animal study was performed at the Laboratory of Department of Physiology, Henan College of Traditional Chinese Medicine, China from June 2007 to February 2008. MATERIALS: A total of 36 male, Sprague Dawley rats, aged 20-21 months, were equally and randomly assigned to the following groups: sham operation, model control, and nimodipine, as well as high-dose, moderate-dose, and low-dose BHD. BHD was composed of milkvetch root, Chinese angelica, red peony root, earthworm, peach seed, safflower, and Szechwan Iovage rhizome, which were provided by the Outpatient Department, Henan College of Traditional Chinese Medicine, China. METHODS: The Chinese medicinal ingredients described above were decocted. The external carotid artery was ligated in rats from the sham operation group. Rat models of focal cerebral infarction were established by middle cerebral artery occlusion in the model control and nimodipine groups, as well as the high-dose, moderate-dose, and low-dose BHD groups. The drugs were administered by gavage 5 days, as well as 2 hours, prior to model induction. Rats in the nimodipine group were daily administered a 6 mg/kg nimodipine suspension by gavage. Rats in the high-dose, moderate-dose, and low-dose BHD groups were administered daily 26, 13, and 6.5 g/kg BHD, respectively. Rats in the sham operation and model control groups were treated with an equal volume of saline. MAIN OUTCOME MEASURES: The effects of BHD on neurological dysfunction score, brain water content, cell proliferation and differentiation in the hippocampal dentate gyrus, and pathological changes in the ischemic brain hemisphere were measured in cerebral infarction rats. RESULTS: Compared with the sham operation group, the neurological dysfunction score, brain water content, number of BrdU-positive cells, BrdU/NeuN-positive cells, and BrdU/GFAP-positive cells in the hippocampal dentate gyrus significantly increased in the model control group (P 〈 0.01 ). Compared with the model control group, neurological dysfunction score and brain water content were significantly decreased (P 〈 0.01 or 0.05), as were the number of BrdU-positive and BrdU/NeuN-positive cells (P 〈 0.01 or 0.05). The number of BrdU/GFAP-positive cells was significantly reduced (P 〈 0.05) in the nimodipine group, high-dose, moderate-dose, and low-dose BHD groups. Compared with the nimodipine group, the neurological dysfunction score was significantly reduced in the moderate-dose BHD group (P 〈 0.05). However, the number of BrdU-positive cells was significantly increased in the rat hippocampal dentate gyrus in the high-dose and moderate-dose BHD groups (P 〈 0.01 or 0.05). The following was determined by microscopy: slightly disarranged neural cells, mild vascular dilatation, inflammatory cell infiltration, and light tissue edema were observed in the nimodipine group; inflammatory celt infiltration was reduced in the low-dose BHD group; cerebral edema and inflammatory cell infiltration were significantly reduced in the high-dose and in the moderate-dose BHD group. Electron microscopy revealed lipofuscin, slightly swollen mitochondria, and normal rough endoplasmic reticulum in the high-dose and moderate-dose BHD groups. Improvement was best in the moderate-dose BHD group. CONCLUSION: Cerebral ischemia activated proliferation of neural stem cells in the rat hippocampal dentate gyrus. The actions of BHD against cerebral ischemia/reperfusion damage correlated with proliferation and differentiation of neural stem cells in the hippocampal dentate gyrus. A moderate-dose of BHD resulted in the most effective outcome.

文摘AIM: To study the effect of Buyang Huanwu Decoction(BYHWD) on the antioxidant enzymes and drug-metabolizing enzymes in rat liver. METHOD: Following treatment of rats with BYHWD at 6.42, 12.83, or 25.66 g·kg–1 per day for 15 days, microsomes and cytosols isolated from the liver tissues were prepared by differential centrifugation according to standard procedures. The activities of the antioxidant enzymes and cytochrome b5, NADPH-cytochrome P450 reductase, CYP3 A, CYP2E1, UGT, and GST of the rat livers were determined by UV-Vis spectrophotometer. RESULTS: The activities of ALT, AST, antioxidant enzymes, and the Hepatosomatic Index in serum were not significantly affected. In cytosols, the activity of CAT was significantly increased at the dosage of 12.83 g·kg–1, and all the other antioxidant activities and MDA levels were not affected by this treatment. BYHWD had no effect on cytochrome b5, NADPH-cytochrome P450 reductase, CYP3 A, and UGT. At the highest dose(25.66 g·kg–1), the activity of CYP2E1 was significantly inhibited, and the activities of GST and the level of GSH were increased. CONCLUSION: BYHWD is safe for the liver, and has the functions of detoxification and antioxidant. Patients should be cautioned about the herb-drug interaction of BYHWD and CYP2E1 substrates.

文摘OBJECTIVE: To study the molecular mechanism of Buyang Huanwu Tang( 补阳还五汤)(BHT) protecting retinal ganglion cells(RGCs) from oxygen induced oxidative stress and apoptosis after anterior ischemia. METHODS: In this study, the Chinese herbs of BHT were extracted by first boiling in water, then were filtered, concentrated, and freeze-dried. The chemical profile of BHT extract was determined by liquid chromatography mass spectrometry(LC-MS). H2O2-induced RGC-5 cells were used as a cell model to investigate the protective effect and mechanism of BHT on RGCs. RESULTS: The survival rate of damaged RGC-5 by BHT was significantly increased by the 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazolium-romid method. Fluorescence activating cell sorter(FACS analysis) showed that BHT could significantly reduce apoptosis induced by oxidative stress via the reactive oxygen species(ROS)-mitogen-activated protein kinase(MAPK)-Caspase-3 signal pathway. CONCLUSION: BHT possesses a high antioxidant capacity and could significantly reduce ROS levels of RGC-5 cells damaged by H2O2.Therefore, the present study has provided possible alternative strategies for the prevention and treatment of ischemic optic disease by using traditional Chinese herbal formulas.

文摘After bilateral carotid artery occlusion for 30 minutes and reperfusion for 2 hours, distinct pathological changes presented in the cerebral cortex and cerebellum of rats. Compared with normal rats, nerve cell membrane fluidity significantly decreased in ischemia/reperfusion rats as detected by spin-labeling electron spin resonance, consistent with order parameter S and rotational correlation time TC measurements. Brain nerve cells from rats with ischemia/reperfusion injury were cultured with 1-100 mg/mL Buyang Huanwu decoction. Results showed that Buyang Huanwu decoction gradually increased membrane fluidity dose-dependently to normal levels, and eliminated hydroxide (OH') and superoxide (O2') free radicals dose-dependenUy. These findings suggest that Buyang Huanwu decoction can protect against cell membrane fluidity changes in rats with ischemia/ reperfusion injury by scavenging free radicals.

文摘Our preliminary studies confirmed that an active principle region of Buyang Huanwu decoction, comprising alkaloid, polysaccharide, aglycon, glucoside and volatile oil, can induce bone marrow mesenchymal stem cell differentiation into neurons. Mitogen-activated protein kinase signaling was identified as one of the key pathways underlying this differentiation process. The present study shows phosphorylated extracellular signal-regulated protein kinase and phosphorylated p38 protein expression was increased after differentiation. Cellular signaling pathway blocking agents, PD98059 and SB203580, inhibited extracellular signal-regulated protein kinase and p38 in mitogen-activated protein kinase signaling pathways respectively, mRNA and protein expression of the neuronal marker, neuron specific enolase, and neural stem cell marker, nestin, were decreased in bone marrow mesenchymal stem cells after treatment with the active principle region of Buyang Huanwu decoction. Experimental findings indicate that, extracellular signal-regulated protein kinase and p38 in mitogen-activated protein kinase signaling pathways participate in bone marrow mesenchymal stem cell differentiation into neuron-like cells, induced by the active principle region of Buyang Huanwu decoction.

文摘Expression of genes in the Notch signaling pathway is altered in the injured spinal cord, which indicates that Notch participates in repair after spinal cord injury. Buyang Huanwu decoction, a traditional Chinese herbal preparation, can promote the growth of nerve cells and nerve fibers; however, it is unclear whether Buyang Huanwu decoction affects the Notch signaling pathway in injured spinal cord. In this study, a rat model was established by injuring the T10 spinal cord. At 2 days after injury, rats were intragastrically administered 2 m L of 0.8 g/m L Buyang Huanwu decoction daily until sacrifice. Real-time reverse transcription polymerase chain reaction analysis demonstrated that at 7, 14 and 28 days after injury, the expression of Notch1 was increased in the Buyang Huanwu decoction group compared with controls. These findings confirm that Buyang Huanwu decoction can promote the expression of Notch1 in rats with incomplete spinal cord injury, and may indicate a mechanism to promote the repair of spinal cord injury.

METHODS: This experiment was carried out in the Laboratory of Nuclear Medicine, Guangzhou University of Traditional Chinese Medicine between September and December 2004. ①The seven influencing factors were selected: such as Shenghuangqi , Dangguiwei, Chishao, Dilong, Taoren, Honghua, Chuanxiong. Each factor was divided into two levels, selected or not selected. The tests were arranged according to L8 (27) orthogonal test table. ②The specific binding of 3H-PAF to its receptors in rabbits was measured by radioligand binding assay. The inhibitory rate of the specific binding was used as an assessing index. The inhibitory action of and on 3H-PAF to PAFR binding was analyzed and compared in vitro. The inhibitory action of each ingredient in the prescription BHD on 3H-PAF to PAFR binding was investigated and compared in vitro by direct analysis and analysis of variance of orthogonal test. MAIN OUTCOME MEASURES: Effect of 8 prescriptions for L8 (27) orthogonal test table on the specific binding inhibition rate of 3H-PAF and PAFR. RESULTS: According to results of variance analysis of orthogonal test, the inhibitory action of each ingredient in the prescription BHD on 3H-PAF to PAFR binding from the highest to the lowest was in turn Honghua, ShenghuangqL Taoren, Dilong, DangguiweL Chuanxiong, Chishao. Honghua, Shenghuangqi, Taoren, Dilong, Danguiwei were major influence factors to 3H-PAF to PAFR in rabbits (F = 187.829,144.446,59.521,5.018,4.265, P 〈 0.05- 0.01), but Chuanxiong and Chishao had not obviously inhibitory effect. The specific binding inhibition rate of prescriptions (except Shenghuangqi ) was obviously higher than that of one of prescriptions (Shenghuangqi included). CONCLUSION: The results of orthogonal test show that Honghua, ShenghuangqL Taoren, Dilong, Dangguiwei are major influencing factors to inhibit binding of sH-PAF to PAFR in rabbits, among which, Honghua is the strongest in ingredients of prescription BHD. The results also reveal that Shenghuangqi is able to weaken the inhibitory effect and to prevent the strong inhibitory effect of blood-activating drugs in BHD.

文摘[Objectives] To evaluate the efficacy and safety of two different treatment regimens( Buyang Huanwu Decoction combined with acupuncture and Buyang Huanwu Decoction alone) in the treatment of apoplectic hemiplegia. [Methods]Electronic databases: China Knowledge Infrastructure( CNKI),Wanfang database( Wan Fang Data),VIP database( VIP),China Biomedical Literature Database( CBM),MEDLINE,The Cochrane Library,Pubmed,Chinese Journal of Integrative Medicine,and Journal of Traditional Chinese Medicine were searched. The published randomized controlled trials( RCT) of Buyang Huanwu Decoction combined with acupuncture and Buyang Huanwu Decoction alone in the treatment of apoplectic hemiplegia were screened. The Jadad scale was used to evaluate the methodological quality of the included literature. The data was extracted and the meta-analysis was carried out with reference to the Systematic Evaluation,Meta-analysis Design and Implementation Method. [Results]A total of 8 articles were included,a total of 765 patients,and there were 8 articles with Jadad scores lower than 4 points. Meta-analysis results indicate that The experimental group of Buyang Huanwu Decoction combined with acupuncture treatment improved the comprehensive clinical efficacy OR = 3. 89,95% CI[2. 58,5. 86]( P < 0. 000 01),BI score SMD = 2. 35,95% CI[2. 04,2. 66]( P <0. 000 01) was better than the control group. [Conclusions]The treatment regimen of Buyang Huanwu Decoction combined with acupuncture can improve the daily activities of patients with apoplectic hemiplegia and improve the clinical efficacy. It is better than the treatment regimen of Buyang Huanwu Decoction alone.
