When great attention is paid to using TCPM in the real world, several problems can be identified: ignoring the Chinese medicine (CM) therapeutic principle based on syndrome differentiation, a lack of appropriate dosage and usage based on individual patient conditions, and a shortage of evidence from randomized, double-blind, placebo-controlled clinical trials. Furthermore, in terms of evaluation of the TCPM effectiveness, few comprehensive criteria and evaluation methods recognized by the international community exist. This article addresses some opinions regarding the above mentioned problems.展开更多

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

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

Because both cardiovascular and cerebrovascular diseases are forms of ischemic vascular disease, they are closely related. We hypothesized that rutaecarpine also has neuroprotective effects on cerebral ischemia reperfusion injury. A cerebral ischemia reperfusion model was established after 84, 252 and 504 pg/kg rutae- carpine were given to mice via intrapedtoneal injection, daily for 7 days. Results of the step through test, 2,3,5-triphenyl tetrazolium chloride dyeing and oxidative stress indicators showed that rutae- carpine could improve learning and memory ability, neurological symptoms and reduce infarction volume and cerebral water content in mice with cerebral ischemia reperfusion injury. Rutaecarpine could significantly decrease the malondialdehyde content and increase the activities of superoxide dismutase and glutathione peroxidase in mouse brain. Therefore, rutaecarpine could improve neu- rological function following injury induced by cerebral ischemia reperfusion, and the mechanism of this improvement may be associated with oxidative stress. These results verify that rutaecarpine has neuroprotective effects on cerebral ischemia reperfusion in mice.展开更多

Rat models were intragastrically administered 5, 10, 20 g/kg Poxue Huayu and Tianjing Busui Decoction, supplemented with Hirudo, raw rhubarb, raw Pollen Typhae, gadfly, Fructrs Trichosanthis, Radix Notoginseng, Rhizoma Acori Talarinowii, and glue of tortoise plastron, once a day, for 14 consecutive days. Results demonstrated that brain water content significantly reduced in rats with cerebral hemorrhage, and intracerebral hematoma volume markedly reduced after treat- ment. Immunohistochemical staining revealed that brain-derived neurotrophic factor, tyrosine kinase B and vascular endothelial growth factor expression noticeably increased around the sur- rounding hematoma. Reverse transcription-PCR revealed that brain-derived neurotrophic factor and tyrosine kinase B mRNA expression significantly increased around the surrounding hematoma. Neurologic impairment obviously reduced. These results indicated that Poxue Huayu and Tianjing Busui Decoction exert therapeutic effects on cerebral hemorrhage by upregulating the expression of brain-derived neurotrophic factor.展开更多

In this study, rat models of focal cerebral ischemia/reperfusion injury were treated with suspended moxibustion at acupoint Dazhui (DU14) for 35 minutes. Results showed that suspended moxibustion decreased infarct volume, reduced cortical myeloperoxidase activity, and suppressed serum levels of proinflammatory cytokines in rats with focal cerebral ischemia/reperfusion injury. Our experimental findings indicated that heat-sensitive moxibustion can attenuate inflammation and promote repair after focal cerebral ischemia/reperfusion injury.展开更多

Because of its inconvenient application and toxic components (Cinnabaris andRealgar), we used transdermal enhancers to deliverAngong Niuhuang pill by modern technology, which expanded the safe dose range and clinical indications. In this study, Angong Niuhuang stickers administered at different point application doses (1.35, 2.7, and 5.4 g/kg) were administered to theDazhui (DU14), Qihai(RN6) andMingmen (DU4) of rats with chronic cerebral ischemia, for 4 weeks. The Morris water maze was used to determine the learning and memory ability of rats. Hematoxylin-eosin staining and Nissl staining were used to observe neuronal damage of the cortex and hippocampal CA1 region in rats with chronic cerebral ischemia. The middle- and high-dose point application ofAngong Niuhuangstickers attenuated neuronal damage in the cortex and hippocampal CA1 region, and improved the memory of rats with chronic cerebral ischemia with an efifcacy similar to interventions by electroacupuncture at Dazhui (DU14),Qihai (RN6) andMingmen (DU4). Our experimental ifndings indicate that point application withAngong Niuhuang stickers can improve cognitive function after chronic cerebral ischemia in rats and is neuroprotective with an equivalent efifcacy to acupuncture.展开更多

Salvianolate exerts a protective effect in various mi- crocirculatory disturbance-related diseases, but studies of the mechanisms underlying its protective action have mainly focused on the myocardium, whereas little research has been carried out in brain tissue following ischemia-reperfusion. We assessed the neuroprotective effects of salvianolate in a rat model of cerebral ischemia-reperfusion injury induced using the suture method. At onset and 24 and 48 hours after reperfusion, rats were intraperitoneally injected with salvianolate (18 mg/kg) or saline. Neurological deficit scores at 72 hours showed that the neurological functions of rats that had received salvianolate were significantly better than those of the rats that had received saline. 2,3,5-Triphenyltetrazolium chloride was used to stain cerebral tissue to determine the extent of the infarct area. A significantly smaller infarct area and a significantly lower number of apoptotic cells were observed after treatment with salvianolate compared with the saline treatment. Expression of heat shock protein 22 and phosphorylated protein kinase B in ischemic brain tissue was significantly greater in rats treated with salvianolate compared with rats treated with saline. Our findings suggest that salvianolate provides neuroprotective effects against cerebral ischemia-reperfusion injury by upregulating heat shock protein 22 and phosphorylated protein kinase B expression.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

Immunohistochemical staining showed that transforming growth factor-J31 expression increased, while Golgi matrix protein GM130 expression decreased after cerebral ischemia-reperfusion. Danhong injection was shown to significantly up-regulate the expression of transforming growth factor-131 and GM130, and expres- sion levels peaked at 7 days after reperfusion. At 7 days after cerebral ischemia-reperfusion, Golgi morphology was damaged in untreated rats, while Golgi morphology breakage was not observed after intervention with Danhong injection. These experimental findings indicate that Danhong injec- tion can up-regulate the expression of transforming growth factor-131 and GM130, and maintain Golgi stability, thus playing a neuroprotective role in rats after cerebral ischemia-reperfusion.展开更多

Acupuncture treatment for acute cerebral ischemia produces abnormal protein expression. OBJECTIVE: To investigate the effects of acupuncture on NF-KB, ICAM-1, and VCAM-1 mRNA and protein expression in the brain tissue of rats with cerebral ischemiaJreperfUsion injury. DESIGN, TIME AND SETTING: Randomized, controlled, animal experiments were performed at the Laboratory of Department of Neurosurgery, Xiangya Hospital, Central South University, China between December 2008 and October 2009. MATERIALS: Rabbit anti-NF-KB polyclonal antibody, rabbit anti-ICAM-1 polyclonal antibody, and rabbit anti-VCAM-1 polyclonal antibody were purchased from Santa Cruz Biotechnology, USA. METHODS: A total of 46 healthy, Sprague Dawley rats were randomly assigned to sham surgery (n= 10), model (n = 12), acupuncture pretreatment (n = 12), and acupuncture intervention (n = 12) groups. Models of middle cerebral artery occlusion were established by right common carotid artery ligation. In the acupuncture pretreatment group, rats received acupuncture for 3 consecutive days, and then models were established. In the acupuncture intervention group, rats received acupuncture for 3 consecutive days at Waiguan (SJ 5), Sanyinjiao (SP 6), and Dazhui (DU 14) acupoints following model establishment. MAIN OUTCOME MEASURES: Somatosensory asymmetry and forelimb use asymmetry were tested, as well as NF-KB, ICAM-1, and VCAM-1 mRNA and protein expression in the frontal and parietal cortex at 4, 12, 24, 48 and 72 hours following cerebral ischemia/reperfusion injury. RESULTS: Acupuncture improved neurological function and significantly decreased NF-KB, ICAM-1, and VCAM-1 mRNA and protein expression in the frontal and parietal cortex of rats with cerebral ischemia/reperfusion injury (P 〈 0.05). CONCLUSION: Acupuncture can improve neurological function, potentially via inhibition of NF-κB, ICAM,I, and VCAM-1 mRNA and protein expression in the frontal and parietal cortex of rats with cerebral ischemia/reperfusion injury.展开更多

文摘Objective:To study the correlation between cerebral small vascular disease and constitution types of Traditional Chinese Medicine(TCM).Methods:The severity of lacunar infarction and leukoaraiosis were graded in 230 patients with cerebral small vascular disease,and they were divided into TCM constitution types.The survey of TCM constitution types was carried out by using standardized TCM constitution scale,and order multivariate Logistic regression was used to analyze the correlation between TCM constitution types with severity of lacunar infarction and leukoaraiosis.Results:Yang-deficiency(阳虚)constitution,blood-stasis constitution and phlegm-dampness constitution were the most common TCM constitution types in patients with lacunar infarction,accounting for 33.7%,12.5%,11.5%respectively.Yang-deficiency constitution,blood-stasis constitution and Yin-deficiency(阴虚)constitution were the most common TCM constitution types in patients with leukoaraiosis,accounting for 28.8%,18.5%,13.7%respectively.There were significant differences in lacunar infarction of Yang-deficiency constitution and blood stasis constitution(P<0.05),and there were significant differences in leukoaraiosis of phlegmdampness constitution and blood-stasis constitution(P<0.05).Single factor analysis showed that the main risk factors of lacunar infarction were age,smoking,alcohol consumption,Yang-deficiency constitution and blood-stasis constitution,and the main risk factors of leukoaraiosis were age,smoking,hypertensive disease,phlegm-dampness constitution and blood-stasis constitution.The ordered multivariate Logistic regression analysis found that the severity of lacunar infarction was closely related to age,and the severity of leukoplosis was closely related to age,smoking and hypertension disease.Conclusion:TCM constitution types of lacunar infarction in patients with small cerebral vascular disease is mainly Yang-deficiency constitution and blood-stasis constitution,and the risk factors include age,smoking,alcohol consumption,Yang-deficiency constitution and blood-stasis constitution.Age is closely related with lacunar infarction.TCM constitution types with leukoaraiosis are mainly phlegm-dampness constitution and blood-stasis constitution,and the risk factors are age,smoking,hypertension disease,phlegm-dampness constitution and blood-stasis constitution.Age,smoking and hypertension disease are closely related with leukoaraiosis.
文摘OBJECTIVE Our previous studies demonstrated that various ingredients from the traditional Chinese medicine(TCM)for promoting blood circulation and removing blood stasis,as exemplified by cryptotanshinone and salvianolic acid B,exerted striking effects on modulating angiogenesis and vascular permeability,which suggests that they may be effective in treating vascular leak-driven diseases(e.g.tumor,cerebral cavernous malformation and diabetic retinopathy).However,the lack of reliable and advanced technologies and models sets up difficult hurdles for better understanding the role of TCM for promoting blood circulation and removing blood stasis.To this end,this study is to outline numerous cutting-edge platforms that can be utilized for exploring the function of TCM for promoting blood circulation and removing blood stasis in vascular leak-driven diseases.METHODS Two-photon laser scanning fluorescence microscopy was used to observe the interactions between neutrophils and blood vessels in a real-time manner.Dynamic flow system was employed to mimic the in vivo behaviors of neutrophils.RIP1-Tag5 spontaneous pancreatic cancer model was used to study the function of tumor blood vessels.CCM2ECKO(deletion of CCM2 in endothelial cells)mice were employed to establish the cerebral cavernous malformation(CCM)animal model.Micro-computed tomography(micro-CT)was utilized to assess the CCM lesion.Müller cell-knockout mouse model was used to study the progression of diabetic retinopathy.Vascular permeability in this model was assessed by fluorescein angiography.RESULTS The interactions between neutrophils and endothelial cells involve a series of complicated processes,including rolling,adhesion,intraluminal crawling and transmigration,which were all monitored in vivo by two-photon laser scanning fluorescence microscopy in a real-time manner.Dynamic flow system was capable of recapitulating the biological behaviors of neutrophils in vitro.Tumor vascular function in particular vascular perfusion could be assessed in the RIP1-Tag5 spontaneous pancreatic cancer model.In terms of CCM studies,specific deletion of CCM2 in endothelial cells resulted in the initiation of CCM lesion.The size and number of CCM lesions could be visualized and quantified by micro-CT.Furthermore,the Müller cell-knockout mouse model was able to precisely reflect the clinical symptoms of diabetic retinopathy.Vascular leak could be monitored at different time points using fluorescein angiography.CONCLUSION An array of high technologies and animal models can be used in investigating the occurrence and progression of multiple vascular leak-driven diseases.The pre-clinical and clinical studies of TCM for promoting blood circulation and removing blood stasis provide fundamental support for the application of the above-mentioned platforms,with the purpose of uncovering the scientific basis of TCM for promoting blood circulation and removing blood stasis.

文摘BACKGROUND On June 30,2021,China received certification from the World Health Organization for malaria elimination.However,this certification does not signify the absence of malaria within China.Due to the increasing frequency of international exchanges and collaborations,the threat of imported malaria persists in China.Consequently,the prevention and control of imported malaria have become a primary focus for our country to maintain its malaria elimination status.CASE SUMMARY Herein,we present a case report of a 53-year-old Chinese man who worked in Africa for nearly two years.He was diagnosed with malaria in the Democratic Republic of the Congo between November 19 and November 23,2022.After receiving effective treatment with oral antimalarial drugs,his condition improved,allowing him to return to China.He was later admitted to our hospital on January 12,2023,during the coronavirus disease 2019 pandemic in Huangshi,China.Through a thorough evaluation of the patient's symptoms,clinical signs,imaging and laboratory test results,and epidemiological data,he was rapidly diagnosed with severe cerebral malaria.The patient underwent successful treatment through a series of intensive care unit interventions.CONCLUSION The successful treatment of this imported case of severe cerebral malaria provides a valuable reference for managing patients with similar malaria infections and has significant clinical implications.
文摘Nowadays, a great number of traditional Chinese patent medicine (TCPM) are used more and more widely to treat cerebral infarction in China. When great attention is paid to using TCPM in the real world, several problems can be identified: ignoring the Chinese medicine (CM) therapeutic principle based on syndrome differentiation, a lack of appropriate dosage and usage based on individual patient conditions, and a shortage of evidence from randomized, double-blind, placebo-controlled clinical trials. Furthermore, in terms of evaluation of the TCPM effectiveness, few comprehensive criteria and evaluation methods recognized by the international community exist. This article addresses some opinions regarding the above mentioned problems.

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Salidroside,the main active ingredient extracted from Rhodiola crenulata,has been shown to be neuroprotective in ischemic cerebral injury,but the underlying mechanism for this neuroprotection is poorly understood.In the current study,the neuroprotective effect of salidroside on cerebral ischemia-induced oxidative stress and the role of the nuclear factor erythroid 2-related factor 2(Nrf2)pathway was investigated in a rat model of middle cerebral artery occlusion.Salidroside(30 mg/kg)reduced infarct size,improved neurological function and histological changes,increased activity of superoxide dismutase and glutathione-S-transferase,and reduced malon-dialdehyde levels after cerebral ischemia and reperfusion.Furthermore,salidroside apparently increased Nrf2 and heme oxygenase-1 expression.These results suggest that salidroside exerts its neuroprotective effect against cerebral ischemia through anti-oxidant mechanisms and that activation of the Nrf2 pathway is involved.The Nrf2/antioxidant response element pathway may become a new therapeutic target for the treatment of ischemic stroke.

文摘Rutaecarpine, an active component of the traditional Chinese medicine Tetradium ruticarpum, has been shown to improve myocardial ischemia repeffusion injury. Because both cardiovascular and cerebrovascular diseases are forms of ischemic vascular disease, they are closely related. We hypothesized that rutaecarpine also has neuroprotective effects on cerebral ischemia reperfusion injury. A cerebral ischemia reperfusion model was established after 84, 252 and 504 pg/kg rutae- carpine were given to mice via intrapedtoneal injection, daily for 7 days. Results of the step through test, 2,3,5-triphenyl tetrazolium chloride dyeing and oxidative stress indicators showed that rutae- carpine could improve learning and memory ability, neurological symptoms and reduce infarction volume and cerebral water content in mice with cerebral ischemia reperfusion injury. Rutaecarpine could significantly decrease the malondialdehyde content and increase the activities of superoxide dismutase and glutathione peroxidase in mouse brain. Therefore, rutaecarpine could improve neu- rological function following injury induced by cerebral ischemia reperfusion, and the mechanism of this improvement may be associated with oxidative stress. These results verify that rutaecarpine has neuroprotective effects on cerebral ischemia reperfusion in mice.

文摘The fermented Chinese formula Shuan-Tong-Ling is composed of radix puerariae(Gegen),salvia miltiorrhiza(Danshen),radix curcuma(Jianghuang),hawthorn(Shanzha),salvia chinensis(Shijianchuan),sinapis alba(Baijiezi),astragalus(Huangqi),panax japonicas(Zhujieshen),atractylodes macrocephala koidz(Baizhu),radix paeoniae alba(Baishao),bupleurum(Chaihu),chrysanthemum(Juhua),rhizoma cyperi(Xiangfu) and gastrodin(Tianma),whose aqueous extract was fermented with lactobacillus,bacillus aceticus and saccharomycetes.ShuanTong-Ling is a formula used to treat brain diseases including ischemic stroke,migraine,and vascular dementia.Shuan-Tong-Ling attenuated H_2O_2-induced oxidative stress in rat microvascular endothelial cells.However,the potential mechanism involved in these effects is poorly understood.Rats were intragastrically treated with 5.7 or 17.2 m L/kg Shuan-Tong-Ling for 7 days before middle cerebral artery occlusion was induced.The results indicated Shuan-Tong-Ling had a cerebral protective effect by reducing infarct volume and increasing neurological scores.Shuan-Tong-Ling also decreased tumor necrosis factor-α and interleukin-1β levels in the hippocampus on the ischemic side.In addition,Shuan-Tong-Ling upregulated the expression of SIRT1 and Bcl-2 and downregulated the expression of acetylated-protein 53 and Bax.Injection of 5 mg/kg silent information regulator 1(SIRT1) inhibitor EX527 into the subarachnoid space once every 2 days,four times,reversed the above changes.These results demonstrate that Shuan-Tong-Ling might benefit cerebral ischemia/reperfusion injury by reducing inflammation and apoptosis through activation of the SIRT1 signaling pathway.

文摘This study established a rat model of cerebral hemorrhage by injecting autologous anticoagulated blood. Rat models were intragastrically administered 5, 10, 20 g/kg Poxue Huayu and Tianjing Busui Decoction, supplemented with Hirudo, raw rhubarb, raw Pollen Typhae, gadfly, Fructrs Trichosanthis, Radix Notoginseng, Rhizoma Acori Talarinowii, and glue of tortoise plastron, once a day, for 14 consecutive days. Results demonstrated that brain water content significantly reduced in rats with cerebral hemorrhage, and intracerebral hematoma volume markedly reduced after treat- ment. Immunohistochemical staining revealed that brain-derived neurotrophic factor, tyrosine kinase B and vascular endothelial growth factor expression noticeably increased around the sur- rounding hematoma. Reverse transcription-PCR revealed that brain-derived neurotrophic factor and tyrosine kinase B mRNA expression significantly increased around the surrounding hematoma. Neurologic impairment obviously reduced. These results indicated that Poxue Huayu and Tianjing Busui Decoction exert therapeutic effects on cerebral hemorrhage by upregulating the expression of brain-derived neurotrophic factor.

文摘Heat-sensitive moxibustion has neuroprotective effects against focal cerebral ischemia/reperfusion injury, however its mechanism of action remains unclear. In this study, rat models of focal cerebral ischemia/reperfusion injury were treated with suspended moxibustion at acupoint Dazhui (DU14) for 35 minutes. Results showed that suspended moxibustion decreased infarct volume, reduced cortical myeloperoxidase activity, and suppressed serum levels of proinflammatory cytokines in rats with focal cerebral ischemia/reperfusion injury. Our experimental findings indicated that heat-sensitive moxibustion can attenuate inflammation and promote repair after focal cerebral ischemia/reperfusion injury.

文摘Angong Niuhuang pill, a Chinese materia medica preparation, can improve neurological func-tions after acute ischemic stroke. Because of its inconvenient application and toxic components (Cinnabaris andRealgar), we used transdermal enhancers to deliverAngong Niuhuang pill by modern technology, which expanded the safe dose range and clinical indications. In this study, Angong Niuhuang stickers administered at different point application doses (1.35, 2.7, and 5.4 g/kg) were administered to theDazhui (DU14), Qihai(RN6) andMingmen (DU4) of rats with chronic cerebral ischemia, for 4 weeks. The Morris water maze was used to determine the learning and memory ability of rats. Hematoxylin-eosin staining and Nissl staining were used to observe neuronal damage of the cortex and hippocampal CA1 region in rats with chronic cerebral ischemia. The middle- and high-dose point application ofAngong Niuhuangstickers attenuated neuronal damage in the cortex and hippocampal CA1 region, and improved the memory of rats with chronic cerebral ischemia with an efifcacy similar to interventions by electroacupuncture at Dazhui (DU14),Qihai (RN6) andMingmen (DU4). Our experimental ifndings indicate that point application withAngong Niuhuang stickers can improve cognitive function after chronic cerebral ischemia in rats and is neuroprotective with an equivalent efifcacy to acupuncture.
文摘Stroke remains a worldwide health problem. Salvianolate exerts a protective effect in various mi- crocirculatory disturbance-related diseases, but studies of the mechanisms underlying its protective action have mainly focused on the myocardium, whereas little research has been carried out in brain tissue following ischemia-reperfusion. We assessed the neuroprotective effects of salvianolate in a rat model of cerebral ischemia-reperfusion injury induced using the suture method. At onset and 24 and 48 hours after reperfusion, rats were intraperitoneally injected with salvianolate (18 mg/kg) or saline. Neurological deficit scores at 72 hours showed that the neurological functions of rats that had received salvianolate were significantly better than those of the rats that had received saline. 2,3,5-Triphenyltetrazolium chloride was used to stain cerebral tissue to determine the extent of the infarct area. A significantly smaller infarct area and a significantly lower number of apoptotic cells were observed after treatment with salvianolate compared with the saline treatment. Expression of heat shock protein 22 and phosphorylated protein kinase B in ischemic brain tissue was significantly greater in rats treated with salvianolate compared with rats treated with saline. Our findings suggest that salvianolate provides neuroprotective effects against cerebral ischemia-reperfusion injury by upregulating heat shock protein 22 and phosphorylated protein kinase B expression.

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The cerebral ischemia-reperfusion model was established using the suture occlusion method, and rats were intraperitoneally given 8 mL/kg Danhong injection once a day prior to model establishment Rat brain tissues were harvested at 6, 24, 48, 72 hours after reperfusion. Immunohistochemical staining showed that transforming growth factor-J31 expression increased, while Golgi matrix protein GM130 expression decreased after cerebral ischemia-reperfusion. Danhong injection was shown to significantly up-regulate the expression of transforming growth factor-131 and GM130, and expres- sion levels peaked at 7 days after reperfusion. At 7 days after cerebral ischemia-reperfusion, Golgi morphology was damaged in untreated rats, while Golgi morphology breakage was not observed after intervention with Danhong injection. These experimental findings indicate that Danhong injec- tion can up-regulate the expression of transforming growth factor-131 and GM130, and maintain Golgi stability, thus playing a neuroprotective role in rats after cerebral ischemia-reperfusion.

文摘BACKGROUND: Nuclear factor-κB (NF-κB), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) in brain tissue can participate in inflammatory reactions after cerebral ischemia. Acupuncture treatment for acute cerebral ischemia produces abnormal protein expression. OBJECTIVE: To investigate the effects of acupuncture on NF-KB, ICAM-1, and VCAM-1 mRNA and protein expression in the brain tissue of rats with cerebral ischemiaJreperfUsion injury. DESIGN, TIME AND SETTING: Randomized, controlled, animal experiments were performed at the Laboratory of Department of Neurosurgery, Xiangya Hospital, Central South University, China between December 2008 and October 2009. MATERIALS: Rabbit anti-NF-KB polyclonal antibody, rabbit anti-ICAM-1 polyclonal antibody, and rabbit anti-VCAM-1 polyclonal antibody were purchased from Santa Cruz Biotechnology, USA. METHODS: A total of 46 healthy, Sprague Dawley rats were randomly assigned to sham surgery (n= 10), model (n = 12), acupuncture pretreatment (n = 12), and acupuncture intervention (n = 12) groups. Models of middle cerebral artery occlusion were established by right common carotid artery ligation. In the acupuncture pretreatment group, rats received acupuncture for 3 consecutive days, and then models were established. In the acupuncture intervention group, rats received acupuncture for 3 consecutive days at Waiguan (SJ 5), Sanyinjiao (SP 6), and Dazhui (DU 14) acupoints following model establishment. MAIN OUTCOME MEASURES: Somatosensory asymmetry and forelimb use asymmetry were tested, as well as NF-KB, ICAM-1, and VCAM-1 mRNA and protein expression in the frontal and parietal cortex at 4, 12, 24, 48 and 72 hours following cerebral ischemia/reperfusion injury. RESULTS: Acupuncture improved neurological function and significantly decreased NF-KB, ICAM-1, and VCAM-1 mRNA and protein expression in the frontal and parietal cortex of rats with cerebral ischemia/reperfusion injury (P 〈 0.05). CONCLUSION: Acupuncture can improve neurological function, potentially via inhibition of NF-κB, ICAM,I, and VCAM-1 mRNA and protein expression in the frontal and parietal cortex of rats with cerebral ischemia/reperfusion injury.
