Abstract
Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. leaves (ESL) are widely used to treat ischemic stroke (IS); however, the specific mechanism remains unclear. The microbiota-gut-brain axis plays a critical role in IS and has become a potential therapeutic target. This study aimed to reveal and verify the therapeutic effect of ESL on IS through the microbiota-gut-brain axis. Ultra-high-performance liquid chromatography coupled with mass spectrometry-based untargeted/targeted metabolomics combined with 16S rRNA microbiota sequencing strategy were used to investigate the regulatory effect of ESL on the metabolism and intestinal microenvironment after IS. Lactobacillus reuteri and Clostridium butyricum were used to treat rats with IS to verify that elevated levels of probiotics are key factors in the therapeutic effect of ESL. The results showed that IS significantly altered the accumulation of 41 biomarkers, while ESL restored their concentrations back to normal. Moreover, ESL alleviated the dysbiosis of gut microbiota brought on by IS, by reducing the abundance of pathogens and increasing the abundance of probiotics (e.g., Lactobacillus reuteri and Clostridium butyricum); this could reduce post-stroke injury, thereby having a certain protective effect on IS. This study reveals that ESL plays an important role in treating IS through the microbiota-gut-brain axis, maintaining metabolic homeostasis in vivo.

Abstract
The gut-brain axis has been shown to play a vital role in the prognosis and recovery of ischemic stroke (IS), which is associated with gut microbiota dysfunction and changes in the gastrointestinal system and epithelial barrier integrity. In turn, gut microbiota and its derived metabolites can influence stroke outcomes. In this review, we first describe the relationship between IS (clinical and experimental IS) and the gut microbiota. Second, we summarize the role and specific mechanisms of microbiota-derived metabolites in IS. Further, we discuss the roles of natural medicines targeting the gut microbiota. Finally, the potential use of the gut microbiota and derived metabolites as a promising therapeutic opportunity for stroke prevention, diagnosis, and treatment is explored.

Abstract
There has been a significant amount of interest in the past two decades in the study of the evolution of the gut microbiota, its internal and external impacts on the gut, and risk factors for cerebrovascular disorders such as cerebral ischemic stroke. The network of bidirectional communication between gut microorganisms and their host is known as the microbiota-gut-brain axis (MGBA). There is mounting evidence that maintaining gut microbiota homeostasis can frequently enhance the effectiveness of ischemic stroke treatment by modulating immune, metabolic, and inflammatory responses through MGBA. To effectively monitor and cure ischemic stroke, restoring a healthy microbial ecology in the gut may be a critical therapeutic focus. This review highlights mechanistic insights on the MGBA in disease pathophysiology. This review summarizes the role of MGBA signaling in the development of stroke risk factors such as aging, hypertension, obesity, diabetes, and atherosclerosis, as well as changes in the microbiota in experimental or clinical populations. In addition, this review also examines dietary changes, the administration of probiotics and prebiotics, and fecal microbiota transplantation as treatment options for ischemic stroke as potential health benefits. It will become more apparent how the MGBA affects human health and disease with continuing advancements in this emerging field of biomedical sciences.

Abstract
BACKGROUND Hyodeoxycholic acid (HDCA) is a natural secondary bile acid with enormous pharmacological effects, such as modulating inflammation in neuron. However, whether HDCA could suppress microglial inflammation has not been elucidated yet. AIMS To determine the anti-microglial inflammatory effect of HDCA in lipopolysaccharide (LPS) models and its mechanisms. METHODS The effect of HDCA was evaluated in LPS-stimulated BV2 microglial cells in vitro and the cortex of LPS-treated mice in vivo. Immunohistochemistry and immunofluorescence were used to visualize the localization of nuclear factor kappa light-chain enhancer of activated B cells (NF-κB) and ionized calcium-binding adaptor protein-1 (Iba-1), respectively. The mRNA expression of inflammatory cytokines was measured by RT-qPCR. The protein expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), takeda G-coupled protein receptor 5 (TGR5), and the phosphorylation of protein kinase B (AKT), NF-κB, and inhibitor of NF-κB protein α (IκBα) was examined by Western blot. RESULTS HDCA inhibited the inflammatory responses in LPS-treated BV2 cells and in the cortex of LPS-treated mice, evidenced by decreased production of inflammatory mediators such as iNOS, COX-2, tumor necrosis factor (TNF-α), interleukin (IL)-6, and IL-1β. Further study demonstrated that HDCA repressed the phosphorylation, nuclear translocation, and transcriptional activity of NF-κB and inhibited the activation of AKT in BV-2 cells induced by LPS. Meanwhile, addition of TGR5 inhibitor, triamterene, abolished the effects of HDCA on TGR5, AKT, and NF-κB. CONCLUSION The present study demonstrated that HDCA prevents LPS-induced microglial inflammation in vitro and in vivo, the action of which is via regulating TGR5/AKT/NF-κB signaling pathway.

Abstract
The burden of neurological and neuropsychiatric disorders continues to grow with significant impacts on human health and social economy worldwide. Increasing clinical and preclinical evidences have implicated that bile acids (BAs) are involved in the onset and progression of neurological and neuropsychiatric diseases. Here, we summarized recent studies of BAs in three types of highly prevalent brain disorders, depression, Alzheimer's disease, and stroke. The shared and specific BA profiles were explored and potential markers associated with disease development and progression were summarized. The mechanistic roles of BAs were reviewed with focuses on inflammation, gut-brain-microbiota axis, cellular apoptosis. We also discussed future perspectives for the prevention and treatment of neurological and neuropsychiatric disorders by targeting BAs and related molecules and gut microbiota. Our understanding of BAs and their roles in brain disorders is still evolving. A large number of questions still need to be addressed on the emerging crosstalk among central, peripheral, intestine and their contribution to brain and mental health.

Abstract
Thyroid hormones (THs) have been suggested to play an important role in both physiological and pathological events in the central nervous system. Hypothyroidism, which is characterized by low levels of serum THs, has been associated with aggravation of ischemic neuronal injuries in stroke patients. We hypothesized that administration of T3, the main active form of THs, may attenuate the ischemic neuronal injuries. In mice, global cerebral ischemia (GCI), which is induced by transient occlusion of the bilateral common carotid artery, causes neuronal injuries by inducing neuronal death and activating inflammatory responses after reperfusion in the hippocampus. In this study, we examined the effect of T3 administration on DNA fragmentation induced by neuronal death and the activation of inflammatory cells such as astrocytes and microglia in the hippocampus following GCI. The content of nucleosomes generated by DNA fragmentation in the hippocampus was increased by GCI and further increased by T3 administration. The protein expression levels of glial fibrillary acidic protein (GFAP), an astrocytic marker, and Ionized calcium binding adaptor protein 1 (Iba1), a microglial marker, in the hippocampus were also increased by GCI and further increased by T3 administration. The levels of T3 in both the serum and hippocampus were elevated by T3 administration. Our results indicate that T3 administration aggravates GCI-reperfusion injury in mice. There may be an increased risk of aggravation of ischemic stroke by the excessive elevation of T3 levels during the drug treatment of hypothyroidism.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Convolvulus pluricaulis Choisy commonly known as Shankhapushpi, is traditionally prescribed for nerve debility, loss of memory, epilepsy and as nervine tonic. Plant also proved to have diverse pharmacological activity but the neuroprotection in ischemic stroke were not found. AIM OF THE STUDY To investigate the effect of Convolvulus pluricaulis against bilateral common carotid artery (BCCA) occlusion induced cerebral ischemic reperfusion injury. MATERIALS AND METHODS The neuroprotective activity of Convolvulus pluricaulis against bilateral common carotid artery (BCCA) occlusion induced cerebral ischemic reperfusion (I/S) injury. Sprague-Dawley rats of either sex (200-250 g) were divided into nine groups of 8 rats each. Sham and control group, saline treated 10 ml/kg orally. Third group treated with Quercetin 25 mg/kg orally and fourth to ninth groups treated with chloroform and ethanol extract of Convolvulus pluricaulis 100, 200, and 400 mg/kg (p.o.) respectively. Control, Quercetin and extract treated groups underwent 30 min BCCA occlusion and 24 h reperfusion on 10th day but sham underwent same surgery without BCCA occlusion and 24 h reperfusion on 10th day. The antioxidant enzymatic and non-enzymatic levels were estimated by UV spectroscopic method and cerebral infarction area, Blood brain barrier disruption, microtubule-associated protein 2 immunohistochemical and histopathological studies were carried out. RESULTS The results of the study indicate that the chloroform and ethanol extract of Convolvulus pluricaulis showed neuroprotective activity by a significant decrease in lipid peroxidation (p < 0.001) and an increase in superoxide dismutase (p < 0.01, p < 0.001), catalase (p < 0.01, p < 0.001), glutathione (p < 0.001), and total thiol (p < 0.001) levels in extract-treated groups as compared to control group. Measurement of cerebral infarction area, blood brain barrier disruption, microtubule-associated protein 2 immunohistochemical and histopathological studies further supported the protective effect of the extract. CONCLUSIONS Present study revile that Convolvulus pluricaulis has potent neuroprotection against bilateral common carotid artery (BCCA) occlusion induced cerebral ischemic reperfusion injury.

Abstract
Acquired brain ischemia-and reperfusion-injury (IRI), including both Ischemic stroke (IS) and Traumatic Brain injury (TBI), is one of the most common causes of disability and death in adults and represents a major burden in both western and developing countries worldwide. China’s clinical neurological therapeutic experience in the use of traditional Chinese medicines (TCMs), including TCM-derived active compounds, Chinese herbs, TCM formulations and decoction, in brain IRI diseases indicated a trend of significant improvement in patients’ neurological deficits, calling for blind, placebo-controlled and randomized clinical trials with careful meta-analysis evaluation. There are many TCMs in use for brain IRI therapy in China with significant therapeutic effects in preclinical studies using different brain IRI-animal. The basic hypothesis in this field claims that in order to avoid the toxicity and side effects of the complex TCM formulas, individual isolated and identified compounds that exhibited neuroprotective properties could be used as lead compounds for the development of novel drugs. China’s efforts in promoting TCMs have contributed to an explosive growth of the preclinical research dedicated to the isolation and identification of TCM-derived neuroprotective lead compounds. Tanshinone, is a typical example of TCM-derived lead compounds conferring neuroprotection toward IRI in animals with brain middle cerebral artery occlusion (MCAO) or TBI models. Recent reports show the significance of the inflammatory response accompanying brain IRI. This response appears to contribute to both primary and secondary ischemic pathology, and therefore anti-inflammatory strategies have become popular by targeting pro-inflammatory and anti-inflammatory cytokines, other inflammatory mediators, reactive oxygen species, nitric oxide, and several transcriptional factors. Here, we review recent selected studies and discuss further considerations for critical reevaluation of the neuroprotection hypothesis of TCMs in IRI therapy. Moreover, we will emphasize several TCM’s mechanisms of action and attempt to address the most promising compounds and the obstacles to be overcome before they will enter the clinic for IRI therapy. We hope that this review will further help in investigations of neuroprotective effects of novel molecular entities isolated from Chinese herbal medicines and will stimulate performance of clinical trials of Chinese herbal medicine-derived drugs in IRI patients.

Abstract
Calculus bovis is commonly used for the treatment of stroke in traditional Chinese medicine. Hyodeoxycholic acid (HDCA) is a bioactive compound extracted from calculus bovis. When combined with cholic acid, baicalin and jas-minoidin, HDCA prevents hypoxia-reoxygenation-induced brain injury by suppressing endoplasmic reticulum stress-mediated apoptotic signaling. However, the effects of HDCA in ischemic stroke injury have not yet been studied. Neurovascular unit (NVU) dysfunction occurs in ischemic stroke. Therefore, in this study, we investigated the effects of HDCA on the NVU under ischemic conditions in vitro. We co-cultured primary brain microvascular endothelial cells, neurons and astrocytes using a transwell chamber co-culture system. The NVU was pre-treated with 10.16 or 2.54 μg/mL HDCA for 24 hours before exposure to oxygen-glucose deprivation for 1 hour. The cell counting kit-8 assay was used to detect cell activity. Flow cytometry and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling were used to assess apoptosis. Enzyme-linked immunosorbent assay was used to measure the expression levels of inflammatory cytokines, including interleukin-1β, interleukin-6 and tumor necrosis factor-α, and neurotrophic factors, including brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor. Oxidative stress-related factors, such as superoxide dismutase, nitric oxide, malondialdehyde and γ-glutamyltransferase, were measured using kits. Pretreatment with HDCA significantly decreased blood-brain barrier permeability and neuronal apoptosis, significantly increased transendothelial electrical resistance and γ-glutamyltransferase activity, attenuated oxidative stress damage and the release of inflammatory cytokines, and increased brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor expression. Our findings suggest that HDCA maintains NVU morphological integrity and function by modulating inflammation, oxidation stress, apoptosis, and the expression of neurotrophic factors. Therefore, HDCA may have therapeutic potential in the clinical management of ischemic stroke. This study was approved by the Ethics Committee of Experimental Animals of Beijing University of Chinese Medicine (approval No. BUCM-3-2016040201-2003) in April 2016.

Anti-Inflammatory Effects of Traditional Chinese Medicines against Ischemic Injury in In Vivo Models of Cerebral Ischemia. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:5739434.

Abstract
Inflammation plays a crucial role in the pathophysiology of acute ischemic stroke. In the ischemic cascade, resident microglia are rapidly activated in the brain parenchyma and subsequently trigger inflammatory mediator release, which facilitates leukocyte-endothelial cell interactions in inflammation. Activated leukocytes invade the endothelial cell junctions and destroy the blood-brain barrier integrity, leading to brain edema. Toll-like receptors (TLRs) stimulation in microglia/macrophages through the activation of intercellular signaling pathways secretes various proinflammatory cytokines and enzymes and then aggravates cerebral ischemic injury. The secreted cytokines activate the proinflammatory transcription factors, which subsequently regulate cytokine expression, leading to the amplification of the inflammatory response and exacerbation of the secondary brain injury. Traditional Chinese medicines (TCMs), including TCM-derived active compounds, Chinese herbs, and TCM formulations, exert neuroprotective effects against inflammatory responses by downregulating the following: ischemia-induced microglial activation, microglia/macrophage-mediated cytokine production, proinflammatory enzyme production, intercellular adhesion molecule-1, matrix metalloproteinases, TLR expression, and deleterious transcription factor activation. TCMs also aid in upregulating anti-inflammatory cytokine expression and neuroprotective transcription factor activation in the ischemic lesion in the inflammatory cascade during the acute phase of cerebral ischemia. Thus, TCMs exert potent anti-inflammatory properties in ischemic stroke and warrant further investigation.

Abstract
Gram-negative pathogen–induced nosocomial infections and resistance are a most serious menace to global public health. Qingfei Xiaoyan Wan (QF), a traditional Chinese medicine (TCM) formula, has been used clinically in China for the treatment of upper respiratory tract infections, acute or chronic bronchitis and pulmonary infection. In this study, the effects of QF on Pseudomonas aeruginosa–induced acute pneumonia in mice were evaluated. The mechanisms by which four typical anti-inflammatory ingredients from QF, arctigenin (ATG), cholic acid (CLA), chlorogenic acid (CGA) and sinapic acid (SPA), regulate anti-inflammatory signaling pathways and related targets were investigated using molecular biology and molecular docking techniques. The results showed that pretreatment with QF significantly inhibits the release of cytokines (TNF-α and IL-6) and chemokines (IL-8 and RANTES), reduces leukocytes recruitment into inflamed tissues and ameliorates pulmonary edema and necrosis. In addition, ATG was identified as the primary anti-inflammatory agent with action on the PI3K/AKT and Ras/MAPK pathways. CLA and CGA enhanced the actions of ATG and exhibited synergistic NF-κB inactivation effects possibly via the Ras/MAPK signaling pathway. Moreover, CLA is speculated to target FGFR and MEK firstly. Overall, QF regulated the PI3K/AKT and Ras/MAPK pathways to inhibit pathogenic bacterial infections effectively.

Abstract
Accumulating epidemiological and clinical evidence shows that inflammation is an important risk factor for various human diseases. Thus, suppressing chronic inflammation has the potential to delay, prevent, and control various chronic diseases, including cerebrovascular, cardiovascular, joint, skin, pulmonary, blood, lymph, liver, pancreatic, and intestinal diseases. Various natural products from traditional Chinese medicine (TCM) have been shown to safely suppress proinflammatory pathways and control inflammation-associated disease. In vivo and/or in vitro studies have demonstrated that anti-inflammatory effects of TCM occur by inhibition of the expression of master transcription factors (for example, nuclear factor-κB (NF-κB)), pro-inflammatory cytokines (for example, tumor necrosis factor-α (TNF-α), chemokines (for example, chemokine (C-C motif) ligand (CCL)-24), intercellular adhesion molecule expression and pro-inflammatory mediators (for example, inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX2)). However, a handful of review articles have focused on the anti-inflammatory activities of TCM and explore their possible mechanisms of action. In this review, we summarize recent research attempting to identify the anti-inflammatory constituents of TCM and their molecular targets that may create new opportunities for innovation in modern pharmacology.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Danhong injection (DH), a Chinese medical product, is used extensively for the treatment of cerebrovascular diseases such as acutely cerebral infarction in clinic. AIM OF THE STUDY To explore the protective effect and the relevant mechanisms of DH on cerebral ischemia-reperfusion (I/R) injury. MATERIALS AND METHODS Cerebral I/R injury was induced through four-vessel occlusion (4-VO) or middle cerebral artery occlusion (MCAO). Adult male SD rats were randomly divided into six kinds of groups: normal control group, sham-operated group, I/R injury group, DH-treated groups at doses of 0.5ml/kg, 1.0ml/kg and 2.0ml/kg. The effects of DH on murine neurological deficits and cerebral infarct volume, 6-keto-prostagladin F(1α) (6-keto-PGF(1α)) level, malondialdehyde (MDA) level and superoxide dismutase (SOD) activity in brain tissue, as well as the activities of plasma tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI) after I/R were evaluated. Moreover, the expressions of Bcl-2 and Bax protein were detected by immunohistochemistry. RESULTS There was no significant difference between the control group and the sham-operated group based on the measurement indicators. Compared with the vehicle-treated group, rats treated with DH showed dose dependent reductions in brain infarction size, and improvement of neurological outcome. The level of 6-keto-PGF(1α) and the activities of SOD and plasma t-PA were enhanced significantly, whereas the level of MDA and the activity of plasma PAI were declined significantly. The immunohistochemical staining results also revealed that the expression of Bcl-2 protein was up-regulated and that of Bax protein was down-regulated when exposed to DH. CONCLUSION DH demonstrates a strong ameliorative effect on cerebral I/R damage in rats by its anticoagulant, antithrombotic, antifibrinolytic and antioxidant activities. Furthermore, suppressing apoptosis through regulating Bcl-2 and Bax protein expressions should be another potential mechanism by which DH exerts its neuroprotective function.

Abstract
AIM OF THE STUDY Traditional Chinese herb Angong Niuhuang Pill (AGNHP) is a famous preparation for neurological diseases; Qingkailing injection (QKL), an extract of AGNHP has similar clinical applications. This investigation was designed to further elucidate the neuroprotective effect of QKL on intracerebral hemorrhage (ICH). MATERIALS AND METHODS ICH was produced in adult Sprague-Dawley rats by injection of collagenase IV. Three incremental doses of QKL injection including low-(0.5 ml/kg), moderate-(1 ml/kg) and high-dosage (2 ml/kg) were administered twice, 3 and 12h following ICH. TUNEL and caspase-3 activity were measured at 1d after ICH, and apomorphine-induced rotation was evaluated at 1d, 7d, 14 d and 28 d. RESULTS Administration of high-dose QKL inhibited TUNEL positive cells (p<0.05) and caspase-3 activity (p<0.05) at 1d following ICH, and reduced apomorphine-induced rotation at 1d (p<0.01), 7d, 14 d and 28 d (p<0.05), compared with the controls. However, QKL in a low or moderate dose had no such effect. CONCLUSION QKL reduced brain damage of intracerebral hemorrhage through inhibiting apoptosis, which suggested a potential intervention for ICH patients.
