Shenmai Injection (SMI), a traditional Chinese medicine with nourishing properties, has been explored for its therapeutic effects in ischemic stroke (IS). This study aimed to evaluate the protective effects of SMI in patients with IS who received intravenous thrombolysis and to elucidate its potential molecular mechanisms through laboratory investigations. Patients with IS were randomized to receive either SMI or a placebo for 10 days within 12 h post-intravenous thrombolysis. Clinical efficacy and safety were assessed. An IS cell model was induced using H2O2, followed by treatment with SMI to explore its therapeutic effects and underlying mechanisms. The modified Rankin Scale (mRS) score at 30 days was significantly lower in the SMI group (n = 35) compared to the placebo group (n = 35), indicating improved functional outcomes. No significant difference was observed in NIHSS scores between the groups. Adverse events and biochemical indices showed no significant differences, confirming the safety of SMI. In the H2O2-induced cell model, SMI enhanced cell viability, reduced apoptosis, and decreased the levels of malondialdehyde (MDA) and reactive oxygen species (ROS). It also improved ATP content and mitochondrial membrane potential. Mechanistic studies revealed that these protective effects were partially mediated through the AMPKα1. SMI significantly improves short-term outcomes in IS patients treated with rt-PA thrombolysis. Its protective effects are likely mediated through the AMPKα1, highlighting its potential as an adjunctive therapy for IS.
Background: Atherosclerosis is a chronic inflammatory disease that leads to ischemic cerebrovascular and cardiovascular diseases. Curcumin, known for its anti-inflammatory properties, may influence the development of atherosclerosis. This study aims to elucidate the effects of curcumin and its mechanisms on atherosclerosis progression. Methods: The proliferative ability, the angiogenesis capacity, and cell migration rate were assessed using cell counting kit-8 (CCK-8), 5-ethynyl-29-deoxyuridine (EdU), tube formation assays, and wound healing, respectively. Furthermore, the protein expression levels of proliferating cell nuclear antigen (PCNA), glycogen synthase kinase 3 beta (GSK3 beta), p-GSK3 beta, beta-catenin, and c-myc were determined utilizing western blot analysis. Results: Oxidized low-density lipoprotein (ox-LDL) significantly triggered cell damage by inhibiting cell proliferation, reducing the migration rate, and angiogenesis capacity in human umbilical vein endothelial cells (HUVECs) (p < 0.05). Curcumin treatment significantly alleviated ox-LDL-induced HUVECs injury (p < 0.05), as evidenced by elevating the proliferative ability (p < 0.05), cell migration (p < 0.05), and angiogenesis (p < 0.05). Moreover, the Wnt/beta-catenin pathway was substantially boosted following ox-LDL treatment (p < 0.05), which was suppressed by curcumin (p < 0.05). Additionally, SKL2001 significantly increased the levels of beta-catenin and c-myc (p < 0.05). The inhibitory effects of curcumin treatment on the Wnt/beta-catenin signaling pathway were reduced by SKL2001 (p < 0.05). Furthermore, the promoting effects of curcumin on ox-LDL-induced cell damage were hampered following SKL2001 treatment in HUVECs (p < 0.05). Conclusion: Curcumin elevated cell proliferation, migration, and angiogenesis of HUVECs to inhibit the development of atherosclerosis through inactivating the Wnt/beta-catenin pathway.
OBJECTIVE:To explore the neuroprotective effects and mechanism of Tanreqing Injection (TRQ) on treating ischemic stroke based on network pharmacology and in vivo experimental validation. METHODS:The chemical compounds of TRQ were retrieved based on published data, with targets retrieved from PubChem, Therapeutic Target Database and DrugBank. Network visualization and analysis were performed using Cytoscape, with protein-protein interaction networks derived from the STRING database. Enrichment analysis was performed using Kyoto Encyclopedia of Genes Genomes pathway and Gene Ontology analysis. In in vivo experiments, the middle cerebral artery occlusion (MCAO) model was used. Infarct volume was determined by 2,3,5-triphenyltetrazolium hydrochloride staining and protein expressions were analyzed by Western blot. Molecular docking was performed to predict ligand-receptor interactions. RESULTS:We screened 81 chemical compounds in TRQ and retrieved their therapeutic targets. Of the targets, 116 were therapeutic targets for stroke. The enrichment analysis showed that the apelin signaling pathway was a key pathway for ischemic stroke. Furthermore, in in vivo experiment we found that administering with intraperitoneal injection of 2.5 mL/kg TRQ every 6 h could significantly reduce the infarct volume of MCAO rats (P<0.05). In addition, protein levels of the apelin receptor (APJ)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway were increased by TRQ (P<0.05). In addition, 41 chemical compounds in TRQ could bind to APJ. CONCLUSIONS:The neuroprotective effect of TRQ may be related to the APJ/PI3K/AKT signaling pathway. However, further studies are needed to confirm the findings.

Background Shenmai injection (SMI) has been used in the treatment of cerebrovascular diseases and cardiovascular diseases. However, the underlying mechanism of SMI for neuroprotection after acute ischemic stroke (AIS) remains unclear. This study aimed to explore the potential molecular mechanism of SMI in treating reperfusion injury after AIS and its protective effect on PC12 cells against oxidative stress through in vitro experiments based on network pharmacological predictions. Methods The network pharmacology method was used to collect the compounds in SMI and AIS damage targets, construct the “drug-disease” target interaction network diagram, screen the core targets, and predict the potential mechanism of SMI treatment of AIS. In addition, the oxidative stress model of PC12 cells was induced by H2O2 to evaluate the neuroprotective effect and predictive mechanism of SMI on PC12 cells. Results A component-targeted disease and functional pathway network showed that 24 components from SMI regulated 77 common targets shared by SMI and AIS. In PC12 cells damaged by H2O2, SMI increased cell survival, alleviated oxidative stress injury, prevented cell apoptosis, and increased the expression of APJ, AMPK, and p-GSK-3β. After Si-APJ silenced APJ expression, the above protective effect of SMI was significantly weakened. Conclusion SMI is characterized by multiple components, multiple targets, and multiple pathways and inhibits oxidative stress and alleviates nerve injury induced by H2O2 through regulating the APJ/AMPK/GSK-3β pathway.
Background: Acute ischemic stroke (AIS) and following reperfusion therapy-induced cerebral ischemia reperfusion (I/R) injury have been recognized as an important subject of cerebrovascular disease with high mortality. Oxidative stress is an important pathological process of cerebral I/R injury. microRNA-19a (miR-19a) is involved in I/R. As the organ protectant agent, Shenmai Injection (SMI) is widely used in the clinical treatment of cerebral infarction. Purpose: This study aims to explore whether SMI can reduce oxidative stress by regulating miR-19a, thereby treating I/R injury. Methods: The oxidative stress state of PC12 cells was induced by H 2 O 2 , and then the cells were cultured with SMI. The therapeutic effect of SMI was evaluated by detecting cellular superoxide dismutase (SOD), malondialdehyde (MDA) and other oxidative markers with the kit. Western blot, PCR, immunofluorescence and other techniques were used to elucidate the potential mechanism of SMI. Results: Cell viability assay results showed that SMI could improve the viability of PC12 cells stimulated by H 2 O 2 . Compared with the H 2 O 2 group, after SMI treatment, the contents of MDA and reactive oxygen species (ROS) were significantly reduced, while the activity of SOD was significantly increased, and SMI could reduce apoptosis by increasing the content of adenosine 5'-triphosphate (ATP) in cells and enhancing the mitochondrial membrane potential (∆Ψm). Western blot and qRT-PCR results showed that these effects were partially achieved through the AMPK/Sirt1/PGC-1α pathway. The level of miR-19a was significantly increased in H 2 O 2 group, and SMI could protect the cells by reducing miR-19a. Further investigated the target of miR-19a, and transfected cells with miR-19a mimic and inhibitor respectively. We found that AdipoR2 was a direct target of miR-19a, and miR-19a could inhibit AdipoR2/PI3K/Akt/mTOR pathway. Conclusion: SMI can activate AMPK/Sirt1/PGC-1α and AdipoR2/PI3K/Akt/mTOR pathways by reducing miR-19a levels, and protect PC12 cells stimulated by H 2 O 2 .
癫痫是神经系统常见疑难病,严重影响患者的生命、生活.五神脏理论是对五神与五脏关系的高度概括,是中医形神统一整体观念的重要体现:通过对五神亢盛调节可协调五脏功能,通过对五脏虚实调理亦可调节五神.癫痫发病特点与五神病变特点有高度相似之处,与五脏相关,且癫痫病因病机复杂,非独一脏一神可言尽,因此,在此基础上提出"五神-五脏-五痫"辨证体系,将神、脏病变特点与癫痫发作特点对应,五脏精准定位,以整体观为核心,调节五神盛衰、五脏虚实,以求保障机体阴阳平衡,有利于患者个体化治疗方案建立,指导癫痫辨证,为癫痫中医临床论治提供新的思路.
对于癫痫的临床诊疗,中、西医各有其优势和不足,因此,有必要从中西医结合的角度梳理癫痫的发作机制,进而探讨癫痫的治疗思路.中医学认为癫痫是由风、火、痰等病理因素影响五脏生理功能,通过经络传递系统作用脑部,使患者神机失常而发病;西医学则认为癫痫是由各种病理因素导致脑部病灶区的神经元电传导机制异常而引起.中、西医学均认为癫痫病位在脑,且两者均为传递信息通路的异常而导致癫痫发作,基于相通的发作机制理论,可借鉴西医学中对于癫痫病灶的定位来为中医治疗提供思路,具体可结合经络辨证,或与头针相结合的思路来进行中医的临床诊疗.
BACKGROUND:Acute ischemic stroke (AIS) is an important factor leading to adult death and disability globally. For AIS patients who meet certain conditions, recombinant tissue plasminogen activator (rt-PA) intravenous thrombolysis is an important method recommended by national guidelines to achieve vascular recanalization. However, complications such as hemorrhagic transformation and vascular reocclusion after thrombolysis are still unsolved problems in clinical. Several systematic reviews of clinical randomized controlled trials (RCTs) in the past have shown that Chinese herbal injections (CHIs) can improve the neurological function of patients, increase the tolerance of ischemic tissues to hypoxia, and inhibit platelet aggregation. Therefore, this study conducted a meta-analysis of AIS treatment with intravenous thrombolysis alone and compared it with the combined application of CHIs. To evaluate whether CHIs have a synergistic effect on thrombolytic therapy and provide a basis for clinical application.METHODS:The following databases will be searched until September 2020: ①English databases: PubMed, Cochrane Library, Embase; ②Chinese databases: CNKI, Wanfang database, Weipu database, SinoMed. RCTs will be included to compare the efficacy of thrombolysis combined with CHIs and thrombolysis alone in the treatment of AIS. Data extraction and risk of bias assessments will be carried out by 2 verifiers independently. The risk of bias will be evaluated through the Cochrane risk of bias tool. Review Manager software 5.3 will be used for statistical analysis.RESULTS:This study will provide comprehensive evidence for the treatment of AIS by CHIs combined with intravenous thrombolysis from multiple aspects.CONCLUSION:The conclusion of the meta-analysis will provide a basis for judging whether CHIs combined with intravenous thrombolysis is an effective measure for the treatment of AIS.ETHICS AND DISSEMINATION:Ethical approval is not needed because this study will be based on data that already published. We will publish the findings of this study in a peer-reviewed journal and related conferences.PROSPERO REGISTRATION NUMBER:CRD42020215546.
