Abstract
BACKGROUND AND PURPOSE Apoptosis is involved in the occurrence and development of acute ischemic stroke (AIS). This study aimed to assess whether Chuanzhitongluo (CZTL), a multi-target and multi-pathway compound preparation, plays a neuroprotective role in AIS by modulating neuronal apoptosis via the PI3K/AKT signaling pathway. METHODS A mouse model of AIS was established by photochemical processes. Cerebral infarction volume was measured by 2% staining with 2, 3, and 5-triphenyl tetrazole chloride (TTC). Neuron apoptosis was assessed by TUNEL staining. Apoptosis RNA arrays were used to detect changes in apoptosis-related gene expression profiles. Western blotting was used to detect proteins involved in the PI3K/AKT signaling pathway. RESULTS The study demonstrated that CZTL could potentially mitigate neuronal apoptosis in AIS mice. This appears to be achieved via the up-regulation of certain genes such as BCL-2, Birc6, and others, coupled with the down-regulation of genes like BAX, Bid, and Casp3. Further validation revealed that CZTL could enhance the expression of BCL-2 and reduce the expression of Cleaved Caspase-3 and BAX at both the gene and protein levels. The study also found that CZTL can enhance the phosphorylation level of the PI3K/AKT signaling pathway. In contrast to these findings, the PI3K inhibitor LY294002 notably amplified neuronal apoptosis in AIS mice. CONCLUSIONS These findings imply that CZTL's ability to inhibit neuronal apoptosis may be linked to the activation of AIS's PI3K/AKT signaling pathway.

Abstract
BACKGROUND In recent years, Salvia miltiorrhiza and its active substances have remarkably progressed in treating central neurological disorders. Tanshinone IIA (TSA) is an active ingredient derived from the rhizome of Salvia miltiorrhiza that has been found to alleviate the symptoms of several psychiatric illnesses. Post-traumatic stress disorder (PTSD) is a mental disorder that results after experiencing a serious physical or psychological injury. The currently used drugs are not satisfactory for the treatment of PTSD. However, it has been reported that TSA can improve PTSD-like symptoms like learning and memory, cognitive disorder, and depression through multi-target regulation. PURPOSE This paper discusses the ameliorative effects of TSA on PTSD-like symptoms and the possible mechanisms of action in terms of inhibition of neuronal apoptosis, anti-neuroinflammation, and anti-oxidative stress. Based on the pathological changes and clinical observations of PTSD, we hope to provide some reference for the clinical transformation of Chinese medicine in treating PTSD. METHODS A large number of literatures on tanshinone in the treatment of neurological diseases and PTSD were retrieved from online electronic PubMed and Web of Science databases. CONCLUSION TSA is a widely studied natural active ingredient against mental illness. This review will contribute to the future development of TSA as a new clinical candidate drug for improving PTSD-like symptoms.

[PMID: 36066030 PMCID: PMC9879188 DOI: 10.1080/15384101.2022.2119687] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 06/09/2022] [Accepted: 08/11/2022] [Indexed: 01/29/2023] Open
Abstract
It was to investigate the neuroprotective mechanism of tanshinone after cerebral infarction via the Kelch-like ECH-associated protein 1 (Keap1)-nuclear factor erythroid 2-related factor 2 (Nrf2)/antioxidant reaction element (ARE) signaling pathway. Forty specific pathogen-free (SPF) Sprague Dawley (SD) rats were selected, all of which were male, approximately seven weeks old, weighing 250 ± 25 g. They were randomly divided into a model group, a non-model operation group, a positive control group, and an experimental group with ten SD rats in each group. The model of cerebral infarction in rats was established by the wire occlusion method. The model group and non-model operation group (control group) were injected with normal saline daily, the negative control group was injected with Keap1 gene inhibitor daily, and the experimental group was injected with tanshinone IIA (10 mg·kg-1·d-1) daily. Animal behavior analysis was performed on the 7th day after the operation, and pathology and the neuroprotective effects of tanshinone IIA on cells were assessed, including cell proliferation, autophagy, oxidative damage, and mitochondrial membrane permeability. The neuroprotective mechanism based on the Keap1-Nrf2/ARE pathway was explored and analyzed. Compared with the model group, the number of Keap1 proteins in the experimental group and the control group was substantially reduced (P < 0.05), and the experimental group was substantially different from the model group (P < 0.01). The protein expression of Nrf2, HO-1, and NQO1 increased substantially (P < 0.05), and the experimental group was substantially different from the model group (P < 0.01). In summary, tanshinone IIA promoted the proliferation of nerve cells, inhibited the production of cellular reactive oxygen species, inhibited the change in mitochondrial membrane potential, and activated the Keap1-Nrf2/ARE signaling pathway. It also induced and regulated the upregulation of downstream NQO1, HO-1, etc. and protected cells from cerebral infarction.

The mechanism of ferroptosis regulating oxidative stress in ischemic stroke and the regulation mechanism of natural pharmacological active components. Biomed Pharmacother 2022; 154:113611. [PMID: 36081288 DOI: 10.1016/j.biopha.2022.113611] [Citation(s) in RCA: 24] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 08/23/2022] [Accepted: 08/24/2022] [Indexed: 02/06/2023] Open
Abstract
Cerebrovascular diseases, such as ischemic stroke, pose serious medical challenges worldwide due to their high morbidity and mortality and limitations in clinical treatment strategies. Studies have shown that reactive oxygen species (ROS)-mediated inflammation, excitotoxicity, and programmed cell death of each neurovascular unit during post-stroke hypoxia and reperfusion play an important role in the pathological cascade. Ferroptosis, a programmed cell death characterized by iron-regulated accumulation of lipid peroxidation, is caused by abnormal metabolism of lipids, glutathione (GSH), and iron, and can accelerate acute central nervous system injury. Recent studies have gradually uncovered the pathological process of ferroptosis in the neurovascular unit of acute stroke. Some drugs such as iron chelators, ferrostatin-1 (Fer-1) and liproxstatin-1 (Lip-1) can protect nerves after neurovascular unit injury in acute stroke by inhibiting ferroptosis. In addition, combined with our previous studies on ferroptosis mediated by natural compounds in ischemic stroke, this review summarized the progress in the regulation mechanism of natural chemical components and herbal chemical components on ferroptosis in recent years, in order to provide reference information for future research on ferroptosis and lead compounds for the development of ferroptosis inhibitors.

Abstract
BACKGROUND AND PURPOSE Chuanzhitongluo (CZTL), a traditional Chinese medicine mixture, is used in the recovery period of acute ischemic stroke (AIS), and effectively improves the prognosis of AIS patients. This study aims to evaluate whether CZTL regulates microglia polarization and inflammatory response to reduce brain damage in the acute phase of AIS. METHODS A mouse model of AIS was prepared by the photochemical method. Cerebral infarct volume was detected by 2,3,5-Triphenyltetrazolium chloride (TTC) staining. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay was used to assess neuronal apoptosis. Gene expression profile change was explored by Gene chip. Inflammatory factors were analyzed by Protein microarray. The Immunofluorescence double-labeling assay was executed to elucidate the effects of CD16+ / Iba-1+ and CD206+ / Iba-1+ in the peripheral area of cerebral ischemia. RESULTS Results revealed that CZTL treatment alleviated the neurological impairment, reduced cerebral infarct volume, and inhibited neuronal apoptosis. CZTL altered gene expression profiles, which indicate that CZTL may be involved in regulating neuroinflammation. CZTL restrained inflammatory responses by down-regulated pro-inflammatory cytokines expression and enhanced anti-inflammatory cytokines level. Further experiments demonstrated that CZTL inhibited the activation of NLRP3 inflammasome, which decreasing the inflammatory response. In addition, CZTL promoted the transformation of microglia from M1 to M2 phenotype. CONCLUSIONS These results indicate that CZTL alleviates neuroinflammation and brain damage after AIS in mice, which may be mediated by modulating microglia polarization.

Abstract
OBJECTIVES To explore the potential neuroprotective mechanism of crocin after cerebral infarction. METHODS The murine hippocampal neuronal cell line HT-22, was used as the study model, with a control group, OGD-group, low-dose crocin group, middle-dose crocin group, and high-dose crocin group. Except for the control-group, cells in the other groups were treated with OGD for 6 h, in which 1 μg/mL, 2 μg/mL and 5 μg/mL of crocin were added in low-dose group, medium-dose group and high-dose group, respectively. Subsequently, the OGD cells were cultured for another 6 h. CCK-8 assay was carried out to detect the cell viability of each group, flow cytometry was used to detect cell apoptosis, immunofluorescence was conducted to detect the expression of reactive oxygen species, and Western Blot was performed to detect the protein expression of p-PI3K, p-Akt, p-mTOR, LC-3 I, LC-3 II, and Beclin-1. RESULTS After hypoxia-reoxygenation treatment, the viability of HT22 cells was remarkably decreased, the apoptosis rate and expression of ROS were significantly increased, the protein expression of p-PI3K, p-Akt and p-mTOR were reduced, while the expression of LC-3 II/I and Beclin-1 were increased. After crocin treatment, the activity of hypoxic reoxygenated cells increased, the apoptosis rate decreased, the expression of reactive oxygen species dropped, the protein expression of p-PI3K, p-Akt and p-mTOR increased, and the expression of LC-3 II/I and Beclin-1 decreased. CONCLUSION At the cellular level, crocin can inhibit autophagy by activating the PI3K/Akt/mTOR pathway, and reduce the level of oxidative stress, thus playing a neuroprotective role.

Abstract
Background Cerebral infarction (CI) is a common brain disease in clinical practice, which is mainly due to the pathological environment of ischemia and hypoxia caused by difficult cerebral circulation perfusion function, resulting in ischemic necrosis of local brain tissue and neurological impairment. In traditional Chinese medicine (TCM) theory, CI is mainly due to blood stasis in the brain. Therefore, blood-activating and stasis-dissipating drugs are often used to treat CI in clinical practice. Salvia miltiorrhiza Bunge (SMB) is a kind of traditional Chinese medicine with good efficacy in promoting blood circulation and removing blood stasis, and treatment of CI with it is a feasible strategy. Based on the above analysis, we chose network pharmacology to investigate the feasibility of SMB in the treatment of CI and to study the possible molecular mechanisms by providing some reference for the treatment of CI with TCM. Methods The active ingredients and related targets of SMB were obtained through the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database, and CI-related targets were obtained from the GeneCards and DisGeNET databases. The target of SMB for the treatment of CI was obtained using Cytoscape software and visualized. GO and KEGG enrichment analysis was performed based on “clusterProfiler” within R, and the prediction results were validated by molecular docking technique. Results By constructing a compound-target (C-T) network, it was found that the active components in SMB mainly treated CI by regulating key proteins such as AKT1, IL-6, and EGFR. These key proteins mainly involve in pathways such as immune regulation, cancer and lipid metabolism, such as lipid and atherosclerosis, chemical carcinogenesis-receptor activation pathways, and IL-17 signaling pathway. In the GO term, it mainly regulates the response to steroid hormones, membrane rafts, and G protein-amine receptor coupled activity. Eventually, we verified that the luteolin and tanshinone IIA components in SMB have a good possibility of action with AKT1 and IL-6 by in silico techniques, indicating that SMB has some scientificity in the treatment of CI. Conclusion SMB mainly treats CI by regulating 94 proteins involved in lipid and atherosclerosis, chemical carcinogenesis-receptor activation, and IL-17 signaling pathway. Our research strategy provided a template for the drug development of TCM for the treatment of CI.

Abstract
Cerebral infarction (CI) has become a leading cause of death in China. Long non-coding RNAs (lncRNAs) are intensively involved in the progression of CI. Here, we aimed to investigate the effects of lncRNA LOC366613 (LOC366613) on cerebral I/R injury, as well as its possible mechanism. Transient middle cerebral artery occlusion (MCAO) was used to establish a mouse model of cerebral I/R, and the PC12 cell line was used to establish an in vitro oxygen-glucose deprivation (OGD) injury model. The MTT assay was used to determine cell viability, and qRT-PCR was used to determine RNA levels. Western blotting was conducted to detect protein expression levels. The TUNEL assay and flow cytometry were used to measure cell apoptosis, and 2,3,5-triphenyltetrazolium chloride (TTC) was used to determine cerebral infarct volume. Finally, RNA pull-down and luciferase activity assays were used to examine interactions between miR-532-5p and LOC366613, as well as between miR-532-5p and phosphatase and tensin homolog (PTEN). LOC366613 was overexpressed in patients with cerebral I/R injury. In PC12 cells, knockdown of LOC366613 reduced the apoptosis rate and lactic acid dehydrogenase (LDH) expression, while increasing cell viability. Moreover, miR-532-5p was shown to be a target of LOC366613, as predicted. Downregulation of miR-532-5p reversed the effects of LOC366613 knockdown on PC12 cell apoptosis, LDH release, and cell viability. Finally, PTEN was verified as a target of miR-532-5p. LOC366613 participates in cerebral I/R injury by regulating the miR-532-5p/PTEN axis, potentially providing a new CI treatment target.

Abstract
OBJECTIVE Cerebral infarction (CI) is the mayor reason of death in China. Reperfusion is the only immediate treatment for acute cerebral infarction. However, blood reperfusion recovery may cause ischemia-reperfusion (I/R) injuries. The purpose of this study was to investigate the effects of Tetrandrine (TTD) and 3-n-Butylphthalide (NBP) on cerebral I/R injury. MATERIALS AND METHODS I/R was used to establish CI model in vivo. TTD was performed to analyze cerebral infarction volume. OGD was applied to establish CI model in vitro. Flow cytometry and TUNEL assays were utilized to determine the cell death. ELISA was conducted to determine the release of cytokines. mRNA and protein expressions were detected using qRT-PCR and western blot. RESULTS We found that NBP + TTD treatment significantly reduced cerebral infarction volume and inhibited the death of neurons in vivo. Moreover, NBP + TTD treatment suppressed the apoptosis and inflammatory response of neurons in vitro. Additionally, NBP + TTD suppressed the expression of activator transcription factor 2 (ATF2). However, overexpression of ATF2 contributed to the degeneration of neurons. Moreover, ATF2 transcriptionally activated Toll-like receptor 4 (TLR4). NBP + TTD inactivated ATF2/TLR4 signaling. CONCLUSIONS Taken together, TTD combined with NBP protected against cerebral infarction by inhibiting the inflammatory response and neuronal cell apoptosis via inactivating ATF2/TLR4 signaling pathways. This may provide an alternative for I/R injury.

Abstract
Nutrition and rehabilitation are crucial in post-stroke recovery, especially in the elderly. Since stroke is the leading cause of long-term disability, there is a need to promote special, individually tailored nutrition strategies targeting older patients with low motor ability. Chronic stroke survivors have higher risk of developing nutrition-related chronic diseases, such as sarcopenia, anemia, type 2 diabetes mellitus and osteoporosis. Moreover, reduced motor activity, cognitive impairment and depression might be aggravated by poor malnutrition status. Accumulated data suggest that nutritional supplements and neuroprotective diets can be associated with better effectiveness of post-stroke rehabilitation as well as brain recovery. Therefore, this review focuses on preventive strategies that can improve dietary intake and change dietary patterns. We highlight the importance of neuroprotective diets, the problem of dysphagia and the role of nutrition in rehabilitation. This article focuses on potential nutritional supplements and neuroprotective diets that may have an impact on functional recovery during and after rehabilitation. Moreover, a new approach to post-stroke neuroplasticity including the use of agents from marine sources such as fucoxanthin and tramiprosate as compounds that might be used as potential neuroprotectants with antioxidative and anti-inflammatory properties is introduced.

Abstract
Malnutrition is a serious problem in post-stroke patients. Importantly, it intensifies with hospitalization, and is related to both somatic and psychological reasons, as well as is associated with the insufficient knowledge of people who accompany the patient. Malnutrition is a negative prognostic factor, leading to a reduction in the quality of life. Moreover, this condition significantly extends hospitalization time, increases the frequency of treatment in intensive care units, and negatively affects the effectiveness of rehabilitation. Obtaining growing data on the therapeutic effectiveness of new compounds of natural origin is possible through the use of pharmacodynamic and analytical methods to assess their therapeutic properties. The proper supply of nutrients, as well as compounds of natural origin, is an important element of post-stroke therapy, due to their strong antioxidant, anti-inflammatory, neuroprotective and neuroplasticity enhancing properties. Taking the above into account, in this review we present the current state of knowledge on the benefits of using selected substances of natural origin in patients after cerebral stroke.

Abstract
At present, the prevention and control of cardiovascular diseases (CAVDs) has made initial advancements, although the prevention and control of cerebrovascular diseases (CEVDs) has not yet achieved the desired progress. In this paper, we review the prevention and control of CEVDs and CAVDs, and analyze the differences in prevention effects, and the pathological and physiological structures pertaining to CEVDs and CAVDs. Combined with the different effects of low-dose aspirin in the primary prevention of CEVDs and CAVDs by meta-analysis, aspirin plays a more important role in the primary prevention of CAVDs than CEVDs. We recognize the misunderstandings and blind spots concerning prevention and control of CEVDs, which can be summarized as follows: (1) CEVDs and CAVDs can be controlled by the same methods and drugs; (2) considering the same pathological factors for cardiovascular diseases; (3) a lack of understanding of the particularity of CEVDs; (4) a focus on platelets and neglect of cerebrovascular protection. In summary, our research clarifies the differences in the prevention measures and drugs used for CEVDs and CAVDs. Of particular concern is the serious lack of preventive drugs for CEVDs in clinical use. An ideal drug for the prevention of CEVDs should have protective effects on the blood, the vascular endothelium, the blood-brain barrier (BBB), and other related factors. Our review aims to highlight several issues in the current prevention of CEVDs and CAVDs, and to provide an optimized plan for preventive drug discovery.

[PMID: 33971269 DOI: 10.1016/j.phrs.2021.105661] [Citation(s) in RCA: 52] [Impact Index Per Article: 17.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Revised: 04/02/2021] [Accepted: 04/30/2021] [Indexed: 02/07/2023]
Abstract
Tanshinones, lipophilic diterpenes isolated from the rhizome of Salvia miltiorrhiza, have diverse pharmacological activities against human ailments including neurological diseases. In fact, tanshinones have been used to treat heart diseases, stroke, and vascular diseases in traditional Chinese medicine. During the last decade, tanshinones have been the most widely studied phytochemicals for their neuroprotective effects against experimental models of cerebral ischemia and Alzheimer's diseases. Importantly, tanshinone IIA, mostly studied tanshinone for biological activities, is recently reported to attenuate blood-brain barrier permeability among stroke patients, suggesting tanshinone IIA as an appealing therapeutic candidate for neurological diseases. Tanshinone I and IIA are also effective in experimental models of Parkinson's disease, Multiple sclerosis, and other neuroinflammatory diseases. In addition, several experimental studies suggested the pleiotropic neuroprotective effects of tanshinones such as anti-inflammatory, antioxidant, anti-apoptotic, and BBB protectant further value aiding to tanshinone as an appealing therapeutic strategy in neurological diseases. Therefore, in this review, we aimed to compile the recent updates and cellular and molecular mechanisms of neuroprotection of tanshinone IIA in diverse neurological diseases.

Neuroprotective Phytochemicals in Experimental Ischemic Stroke: Mechanisms and Potential Clinical Applications. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:6687386. [PMID: 34007405 PMCID: PMC8102108 DOI: 10.1155/2021/6687386] [Citation(s) in RCA: 45] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 03/10/2021] [Accepted: 03/29/2021] [Indexed: 02/06/2023]
Abstract
Ischemic stroke is a challenging disease with high mortality and disability rates, causing a great economic and social burden worldwide. During ischemic stroke, ionic imbalance and excitotoxicity, oxidative stress, and inflammation are developed in a relatively certain order, which then activate the cell death pathways directly or indirectly via the promotion of organelle dysfunction. Neuroprotection, a therapy that is aimed at inhibiting this damaging cascade, is therefore an important therapeutic strategy for ischemic stroke. Notably, phytochemicals showed great neuroprotective potential in preclinical research via various strategies including modulation of calcium levels and antiexcitotoxicity, antioxidation, anti-inflammation and BBB protection, mitochondrial protection and antiapoptosis, autophagy/mitophagy regulation, and regulation of neurotrophin release. In this review, we summarize the research works that report the neuroprotective activity of phytochemicals in the past 10 years and discuss the neuroprotective mechanisms and potential clinical applications of 148 phytochemicals that belong to the categories of flavonoids, stilbenoids, other phenols, terpenoids, and alkaloids. Among them, scutellarin, pinocembrin, puerarin, hydroxysafflor yellow A, salvianolic acids, rosmarinic acid, borneol, bilobalide, ginkgolides, ginsenoside Rd, and vinpocetine show great potential in clinical ischemic stroke treatment. This review will serve as a powerful reference for the screening of phytochemicals with potential clinical applications in ischemic stroke or the synthesis of new neuroprotective agents that take phytochemicals as leading compounds.

Abstract
The aim of the present study was to investigate the influence of butylphthalide on nerve cell apoptosis in rats with cerebral infarction through the c-Jun N-terminal kinase (JNK)/p38 mitogen-activated protein kinase (MAPK) signaling pathway. A total of 36 Sprague-Dawley rats were randomly divided into sham-operation group (n=12), model group (n=12) and butylphthalide group (n=12). Additionally, qPCR was performed to measure the mRNA expression of Bax and Bcl-2, and a TUNEL assay was conducted to investigate the cell apoptosis. Compared with the sham-operation group, the model group and the butylphthalide group had notably increased Zea-Longa scores (P<0.05), while the butylphthalide group exhibited a markedly decreased Zea-Longa score, compared with the model group (P<0.05). The positive expression of Bax was markedly higher (P<0.05), while that of Bcl-2 was notably lower in the model group and the butylphthalide group (P<0.05), compared with those in the sham-operation group. Furthermore, the positive expression of Bax was notably decreased (P<0.05), while that of Bcl-2 was markedly increased in the butylphthalide group in comparison with those in model group (P<0.05). The model group and the butylphthalide group had markedly higher relative protein expression levels of p-JNK and p-p38 MAPK than the sham-operation group (P<0.05), and the butylphthalide group displayed notably lower relative protein expression levels of p-JNK and p-p38 MAPK than the model group (P<0.05). The relative mRNA expression level of Bax was markedly increased (P<0.05), while that of Bcl-2 was notably decreased in the model group and the butylphthalide group (P<0.05), compared with those in the sham-operation group. Compared with those in the model group, the relative mRNA expression level of Bax decreased markedly (P<0.05), and that of Bcl-2 increased notably in the butylphthalide group (P<0.05). The apoptotic rate was markedly higher in the model group and the butylphthalide group than that in the sham-operation group (P<0.05), but it was notably lower in the butylphthalide group than that in the model group (P<0.05). In conclusion, butylphthalide may inhibit nerve cell apoptosis in rats with cerebral infarction to exert a protective effect, which may be associated with the JNK/p38 MAPK signaling pathway.

Classical Active Ingredients and Extracts of Chinese Herbal Medicines: Pharmacokinetics, Pharmacodynamics, and Molecular Mechanisms for Ischemic Stroke. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:8868941.

Abstract
Stroke is a leading cause of death and disability worldwide, and approximately 87% of cases are attributed to ischemia. The main factors that cause ischemic stroke include excitotoxicity, energy metabolism disorder, Ca+ overload, oxidative damage, apoptosis, autophagy, and inflammation. However, no effective drug is currently available for the comprehensive treatment of ischemic stroke in clinical applications; thus, there is an urgent need to find and develop comprehensive and effective drugs to treat postischemic stroke. Traditional Chinese medicine (TCM) has unique advantages in treating ischemic stroke, with overall regulatory effects at multiple levels and on multiple targets. Many researchers have studied the effective components of TCMs and have achieved undeniable results. This paper reviews studies on the anticerebral ischemia effects of TCM monomers such as tetramethylpyrazine (TMP), dl-3-n-butylphthalide (NBP), ginsenoside Rg1 (Rg1), tanshinone IIA (TSA), gastrodin (Gas), and baicalin (BA) as well as effective extracts such as Ginkgo biloba extract (EGB). Research on the anticerebral ischemia effects of TCMs has focused mostly on their antioxidative stress, antiapoptotic, anti-inflammatory, proangiogenic, and proneurogenic effects. However, the research on the use of TCM to treat ischemic stroke remains incompletely characterized. Thus, we summarized and considered this topic from the perspective of pharmacokinetics, pharmacological effects, and mechanistic research, and we have provided a reference basis for future research and development on anticerebral ischemia TCM drugs.

Abstract
Ischemic stroke is a common neurological disease that can lead to mortality and disability. The current curative effect remains unsatisfactory because drug accumulation in the diseased areas is insufficient as a result of the unique blood–brain barrier. Therefore, much attention has been paid to develop a novel therapeutic compound, paeonol-ozagrel conjugate (POC), for ischemic stroke. Then, POC was successfully synthesized by conjugating of paeonol and ozagrel as mutual prodrug. A series of in vitro characterizations and evaluations, including high - resolution mass spectroscopy, nuclear magnetic resonance spectroscopy, partition coefficient, and assessment of cytotoxicity against PC12 cells, were performed. Pharmacokinetic study demonstrated POC is eliminated quickly (t1/2 = 53.46 ± 19.64 min), which supported a short dosing interval. The neurological score, infarct volume, histopathological changes, oxidative stress, inflammatory cytokines levels, and TXA2 levels also were evaluated in vivo in middle cerebral artery occlusion (MCAO) rats. All results showed that POC had a significant curative and therapeutic effect on ischemic stroke, as evaluated by the middle cerebral artery occlusion. Overall, POC can be expected to become a new drug candidate for the treatment of ischemic stroke.

Abstract
Drug development has long included the systematic exploration of various resources. Among these, natural products are one of the most important resources from which novel agents are developed due to the multiple pharmacologic effects of these natural products on diseases. Tanshinone, a representative natural product, is the main compound extracted from the dried root and rhizome of Salvia miltiorrhiza Bge. Research on tanshinone began in the early 1930s. With the in-depth investigation of an increasing number of identified analogs, tanshinone has demonstrated a wide variety of bioactivities and contradicted the saying, 'You can't teach an old dog new tricks'. This review is focused on the pharmacological action of tanshinone and status of research on tanshinone in recent years. The mechanism of tanshinone has also drawn much attention, with the findings of representative targets and pathways of tanshinone. The most recent studies have comprehensively shown that tanshinone can be used to treat leukemia and solid carcinoma, protect against cardiovascular and cerebrovascular diseases, and alleviate liver- and kidney-related diseases, among its other effects. Multiple signaling pathways, including antiproliferative, antiapoptotic, anti-inflammatory, and antioxidative stress pathways, are involved in its actions.

Abstract
Background Cerebral infarction is a cardiovascular disease with high morbidity and mortality. At present, many studies have reported the treatment of cerebral infarction by traditional Chinese medicine. Naringin, a flavonoid, is a major traditional Chinese medicine. However, the effect and mechanism of naringin on cerebral infarction is unclear. Material/Methods In our study, we established a rat model of cerebral infarction through middle cerebral artery occlusion (MCAO) to study the influence of naringin on cerebral infarction in vivo. After treatment with naringin, brain water content was detected to assess brain edema. Cerebral infarction volume and neurological deficits were also measured. Production of the inflammatory factors tumor necrosis factor (TNF)-α and interleukin (IL)-6) was measured using enzyme-linked immunosorbent assay (ELISA). Besides, the effect of naringin on cerebral infarction was investigated in vitro by establishing an oxygen-glucose deprivation (OGD) model in neuronal cells. Cell apoptosis and cell viability was determined using flow cytometry and MTT assay. Results We found that naringin pretreatment significantly decreased the brain water content, cerebral infarction volume, and neurological deficit scores of MCAO subjected rats. And naringin treatment reduced apoptosis of nerve cells in rat hippocampus and the secretion of inflammatory factor such as TNF-α and IL-6. Besides, we found that naringin increased cell viability and inhibited apoptosis in OGD induced neuronal cells. Finally, we found that naringin promoted the expression of p-AKT protein in a concentration-dependent manner and activated the PI3K/AKT pathway in OGD induced neurons. Conclusions Naringin played a protective role in cerebral infarction via suppressing neuronal apoptosis and inflammation.

Abstract
The present study was designed to investigate the role of microRNA-451 (miRNA-451) on cerebral ischemia-reperfusion and to explore its possible mechanism. The expression of miRNA-451 was downregulated in rats with cerebral ischemia-reperfusion. In an in vitro model of cerebral ischemia-reperfusion, the downregulation of miRNA-451 increased inflammation, demonstrated by increased levels of tumor necrosis factor α, interleukin (IL)-1b, IL-6 and IL-18. However, the upregulation of miRNA-451 expression decreased inflammation in the same in vitro model of cerebral ischemia-reperfusion. In addition, it was found that the downregulation of miRNA-451 induced the expression of Toll-like receptor 4 (TLR4), myeloid differentiation primary response protein MyD88 (MyD88) and nuclear factor-κB (NF-κB)/p65. Moreover, the administration of a MyD88 inhibitor, ST 2825, reduced the expression of MyD88 and NF-κB/p65 in the in vitro model of cerebral ischemia-reperfusion, inhibiting the effects of miRNA-451 upregulation on inflammation. A TLR4 inhibitor, TAK-242, was used to reduce the expression of TLR4 in the in vitro model of cerebral ischemia-reperfusion. TAK-242 suppressed the effects of miRNA-451 downregulation on inflammation. The present study suggested that miRNA-451 regulated cerebral ischemia-reperfusion-induced inflammation, which is mediated through the TLR4/MyD88/NF-κB signaling pathway.

Abstract
OBJECTIVE To investigate the effect of miR-128b on apoptosis and BCL-2 and CAPASE3 expression in a rat middle cerebral artery occlusion (MCAO) model. METHODS The MCAO model was established by the thread embolism method. miR-128b agomir and antagomir were injected into the ventricle of MCAO rats by stereotaxic intracerebral injection. Then the rats were divided into a sham group, model group, miR-128b agomir group, and miR-128b antagomir group. Zea Longa was used to score the modeling rats. The area of cerebral infarction was assessed by 2,3,5-triphenyltetrazolium chloride staining. Apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling assay. The miR-128b relative expression was detected by real-time polymerase chain reaction. The expressions of BCL-2 and CAPASE3 were detected by immunohistochemistry and Western blotting. RESULTS The MCAO model was constructed successfully. The expressions of miR-128b in the MCAO groups were higher than that of the sham group (P < 0.05). Compared with the model group, the cerebral infarction area in the miR-128b agomir group was significantly bigger and that of the miR-128b antagomir group was smaller (P < 0.05). The number of apoptotic cells in the miR-128b agomir group was more and that of miR-128b antagomir group was less (P < 0.05 vs. model group). The BCL-2 expression reduced and CAPASE3 expression increased in the MCAO groups (P < 0.05 vs. sham group). Compared with the model group, the Bcl-2 expression decreased and Caspase 3 expression increased in the miR-128b agomir group, and those in the miR-128b antagomir group were opposite. CONCLUSIONS miR-128b promoted cerebral infarction in MCAO rats by regulating Bcl-2 and Caspase 3 expression.

Tanshinone IIA Attenuates Diabetic Peripheral Neuropathic Pain in Experimental Rats via Inhibiting Inflammation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:2789847. [PMID: 29713362 PMCID: PMC5866893 DOI: 10.1155/2018/2789847] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/09/2017] [Accepted: 01/01/2018] [Indexed: 12/17/2022]
Abstract
Diabetic peripheral neuropathic pain (DPNP) is a common and intractable complication of diabetes. Conventional therapies are always not ideal; development of novel drugs is still needed to achieve better pain relief. Recent evidences have demonstrated that inflammation is involved in the onset and maintenance of DPNP. The anti-inflammatory property of Tanshinone IIA (TIIA) makes it a promising candidate to block or alter the pain perception. This study was conducted to investigate whether TIIA could attenuate DPNP in streptozotocin- (STZ-) induced rats model and its potential mechanisms. TIIA was administered to STZ-induced diabetic rats at the dose of 40 mg/kg once a day for 3 weeks. The effects of TIIA on thermal hyperalgesia and mechanical allodynia were investigated using behavioral tests. The mRNA level and expression of interleukin- (IL-) 1β, interleukin- (IL-) 6, tumor necrosis factor- (TNF-) α, and interleukin- (IL-) 10 in the fourth to sixth segments of the dorsal root ganglion (L4–6 DRG) were detected by quantitative real-time PCR (qPCR) and Western blot. TIIA treatment significantly attenuated mechanical allodynia and thermal hyperalgesia in diabetic rats. In addition, the expression of the proinflammatory cytokines IL-1β, IL-6, and TNF-α was inhibited, and the level of the anti-inflammatory cytokine IL-10 was increased by TIIA. This study demonstrated that TIIA has significant antiallodynic and antihyperalgesic effects in a rat model of STZ-induced DPNP, and the effect may be associated with its anti-inflammation property.
