Zheng T, Jiang T, Huang Z, Ma H, Wang M. Role of traditional Chinese medicine monomers in cerebral ischemia/reperfusion injury:a review of the mechanism. Front Pharmacol 2023; 14:1220862. [PMID: 37654609 PMCID: PMC10467294 DOI: 10.3389/fphar.2023.1220862] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 08/04/2023] [Indexed: 09/02/2023] Open
Abstract
Ischemia/reperfusion (I/R) injury is a pathological process wherein reperfusion of an ischemic organ or tissue exacerbates the injury, posing a significant health threat and economic burden to patients and their families. I/R triggers a multitude of physiological and pathological events, such as inflammatory responses, oxidative stress, neuronal cell death, and disruption of the blood-brain barrier (BBB). Hence, the development of effective therapeutic strategies targeting the pathological processes resulting from I/R is crucial for the rehabilitation and long-term enhancement of the quality of life in patients with cerebral ischemia/reperfusion injury (CIRI). Traditional Chinese medicine (TCM) monomers refer to bioactive compounds extracted from Chinese herbal medicine, possessing anti-inflammatory and antioxidative effects, and the ability to modulate programmed cell death (PCD). TCM monomers have emerged as promising candidates for the treatment of CIRI and its subsequent complications. Preclinical studies have demonstrated that TCM monomers can enhance the recovery of neurological function following CIRI by mitigating oxidative stress, suppressing inflammatory responses, reducing neuronal cell death and functional impairment, as well as minimizing cerebral infarction volume. The neuroprotective effects of TCM monomers on CIRI have been extensively investigated, and a comprehensive understanding of their mechanisms can pave the way for novel approaches to I/R treatment. This review aims to update and summarize evidence of the protective effects of TCMs in CIRI, with a focus on their role in modulating oxidative stress, inflammation, PCD, glutamate excitotoxicity, Ca2+ overload, as well as promoting blood-brain barrier repairment and angiogenesis. The main objective is to underscore the significant contribution of TCM monomers in alleviating CIRI.

Shao X, Chen B, Zhu L, Zhu L, Zheng J, Pu X, Chen J, Xia J, Wu X, Zhang J, Wu D. The Effects of Adding Di-Tan Decoction (DTD) and/or Electroacupuncture (EA) to Standard Swallowing Rehabilitation Training (SRT) for Improving Poststroke Dysphagia (PSD): A Pilot, Single-Centred, Randomized Trial. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2022; 2022:2011597. [PMID: 36532853 PMCID: PMC9754838 DOI: 10.1155/2022/2011597] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 11/24/2022] [Accepted: 11/26/2022] [Indexed: 01/06/2024]
Abstract
OBJECTIVES To evaluate the effect of adding Di-tan decoction (DTD) and/or electroacupuncture (EA) to standard swallowing rehabilitation training (SRT) on improving PSD. METHODS In total, 80 PSD patients were enrolled and randomly assigned to the DTD, EA, DTD + EA or control group at a 1 : 1 : 1 : 1 ratio. All patients received basic treatment and standard SRT. The DTD group received DTD orally, the EA group received EA, the DTD + EA group received both DTD and EA simultaneously, and the control group received only basic treatment and standard SRT. The interventions lasted for 4 weeks. The outcome measurements included the Standardized Swallowing Assessment (SSA) and Swallowing-Quality of Life (SWAL-QOL), performed and scored from baseline to 2, 4, and 6 weeks after intervention, and the Videofluoroscopic Dysphagia Scale (VDS), scored at baseline and 4 weeks after intervention. Scores were compared over time by repeated-measures analysis of variance (ANOVA) among all groups. Interactions between interventions were explored using factorial design analysis. RESULTS (1) The effective rates (ERs) for PSD treatment were higher in the DTD, EA and DTD + EA groups than in the control group (all P < 0.05). The ER was higher in the DTD + EA group than in the DTD or EA group (both P < 0.05). (2) There were significant group effects, time effects and interactions for the SSA and SWAL-QOL scores (all P < 0.05). All groups showed decreasing trends in SSA scores and increasing trends in SWAL-QOL scores over time from baseline to 6 weeks after intervention (all P < 0.01). (3) Factorial design analysis for ΔVDS showed that there was a significant main effect for DTD intervention (F = 11.877, P < 0.01) and for EA intervention (F = 29.357, P < 0.01). However, there was no significant interaction effect between DTD and EA (F = 0.133, P = 0.717). Multiple comparisons showed that the DTD, EA and DTD + EA groups all had higher ΔVDS values than the control group (P < 0.05). The DTD + EA group had a higher ΔVDS than the DTD or EA group (both P < 0.05). (4) Most adverse reactions were mild and transient. CONCLUSIONS Adding DTD or EA to SRT can better improve PSD than applying SRT alone. Adding DTD and EA simultaneously can accelerate and amplify the recovery of swallowing function versus DTD or EA alone, and both are effective and safe treatments, alone or jointly, for PSD and are a powerful supplement to routine treatments.

Leonurine Reduces Oxidative Stress and Provides Neuroprotection against Ischemic Injury via Modulating Oxidative and NO/NOS Pathway. Int J Mol Sci 2022; 23:ijms231710188. [PMID: 36077582 PMCID: PMC9456230 DOI: 10.3390/ijms231710188] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 08/31/2022] [Accepted: 09/01/2022] [Indexed: 11/16/2022] Open
Abstract
Leonurine (Leo) has been found to have neuroprotective effects against cerebral ischemic injury. However, the exact molecular mechanism underlying its neuroprotective ability remains unclear. The aim of the present study was to investigate whether Leo could provide protection through the nitric oxide (NO)/nitric oxide synthase (NOS) pathway. We firstly explored the effects of NO/NOS signaling on oxidative stress and apoptosis in in vivo and in vitro models of cerebral ischemia. Further, we evaluated the protective effects of Leo against oxygen and glucose deprivation (OGD)-induced oxidative stress and apoptosis in PC12 cells. We found that the rats showed anxiety-like behavior, and the morphology and number of neurons were changed in a model of photochemically induced cerebral ischemia. Both in vivo and in vitro results show that the activity of superoxide dismutase (SOD) and glutathione (GSH) contents were decreased after ischemia, and reactive oxygen species (ROS) and malondialdehyde (MDA) levels were increased, indicating that cerebral ischemia induced oxidative stress and neuronal damage. Moreover, the contents of NO, total NOS, constitutive NOS (cNOS) and inducible NOS (iNOS) were increased after ischemia in rat and PC12 cells. Treatment with L-nitroarginine methyl ester (L-NAME), a nonselective NOS inhibitor, could reverse the change in NO/NOS expression and abolish these detrimental effects of ischemia. Leo treatment decreased ROS and MDA levels and increased the activity of SOD and GSH contents in PC12 cells exposed to OGD. Furthermore, Leo reduced NO/NOS production and cell apoptosis, decreased Bax expression and increased Bcl-2 levels in OGD-treated PC12 cells. All the data suggest that Leo protected against oxidative stress and neuronal apoptosis in cerebral ischemia by inhibiting the NO/NOS system. Our findings indicate that Leo could be a potential agent for the intervention of ischemic stroke and highlighted the NO/NOS-mediated oxidative stress signaling.

Abstract
The management of post-stroke complications plays an important role in the quality of life. Di-Tan Decoction (DTD; ) is a widely used traditional Chinese medicine. This study incorporated systematic review and meta-analysis to evaluate the efficacy of DTD in post-stroke neurological disorders. Randomized clinical trials (RCTs) were searched from English, Chinese and Korean electronic medical databases, by including the keywords "Di-Tan Tang", "Di-Tan Decoction", "Scour Phlegm Decoction", "stroke", and "RCT. Each RCT included control (placebo, conventional therapy, or Western medicine) and experimental (DTD treatment) groups. For patients inflicted with stroke for 1-6 weeks, the outcomes of post-stroke neurological disorders were measured by scales for post-stroke symptoms and were classified as "completely healed", "markedly effective", "effective" and "ineffective". Totally, 11 RCTs (n = 490 controls and n = 502 DTD subjects) were selected from 210 articles identified in the initial search. A meta-analysis of evaluation criteria in post-stroke symptoms revealed that the overall odds ratio (ORs) for alleviating post-stroke neurological disorders were 0.30-fold lower (95% CI = 0.21-0.43) in the DTD group than the control (Western medicine) group (P < 0.000 01). Moreover, regardless of the type of stroke diagnostic scale applied (including NFA, HDS, and NIHSS), the overall post-stroke symptoms determined were less severe in the DTD group (n = 219) than the control group (n = 217). No adverse effects of DTD were observed in the 11 RCTs reviewed. All 11 studies used an appropriate method for randomization of subjects to evaluate the risk of bias (ROB), and 7 studies included allocation concealment as well as blinding of patients and practitioners. High-risk ROB was included in 6 RCTs. No significant publication bias was derived from the funnel plot. Our results indicate that the administration of DTD alone, and DTD in combination with Western medicine, exert greater efficacy for post-stroke complication therapy, than Western medicine administered alone. More rigorous and regulated studies are required to confirm the therapeutic efficacy of DTD for post-stroke neurological disorders. disorders.

Abstract
Ischemic stroke is the most prevalent stroke condition in the world resulted in either a transient ischemic attack or long-lasting neurological problems due to the interrupted or reduced blood flow to the brain. Antrodia camphorata is a well-known medicinal mushroom native to Taiwan and is familiar due to its medicinal effects. The current study investigated the protective effect of A. camphorata-alcohol extracts (AC-AE) against cobalt (II) chloride (CoCl2 )-induced oxidative stress in vitro and ischemia/reperfusion-induced brain injury in vivo. The rats were pre-treated with AC-AE for 4 weeks. Our results showed that AC-AE reduced cell damage and decreased reactive oxygen species (ROS) production in C6 and PC12 cells under CoCl2 -induced hypoxic condition. AC-AE doses (385, 770, 1,540 mg/kg/day, 4 weeks) increased nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) mRNA expressions and decreased inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) mRNA expressions in Sprague Dawley rat. Besides, it decreased stroke infarct size and increased the level of antioxidants in both brain and serum. Furthermore, it reduced the formation of malondialdehyde (MDA) after ischemia/reperfusion (I/R). Our results suggested that AC-AE exerted an effective reduction of ischemia stroke by regulating ROS production.

Abstract
Neurological sicknesses are serious, multifactorial, debilitating disorders that may cause neurodegeneration. Neuroprotection is the protection of the structure and capacity of neurons from affronts emerging from cell injuries instigated by an assortment of specialists or neurodegenerative diseases. Various neurodegenerative diseases, including Alzheimer's, Parkinson's, and epilepsy, afflict many people worldwide, with increasing age representing the leading risk factor. Crocin is a natural carotenoid compound which was found to have therapeutic potentials in the management of the neurological disease. In this review, we focused on the restorative capabilities of Crocin as a neuroprotective agent. The general neuroprotective impact and the various conceivable basic components identified with Crocin have been examined. In light of the substantial proof indicating the neuro-pharmacological viability of Crocin to different exploratory standards, it is concluded that Crocin exerts direct antioxidant, antiapoptotic and anti-inflammatory activities by multiple signaling pathways. Besides, Crocin was found to elevate dopamine level in the brain during the experimental model of Parkinson's disease. Thus, this compound has been demonstrated to be a promising option for the treatment of neurodegenerative diseases, with few adverse effects. It ought to be further considered as a potential contender for neuro-therapeutics, concentrating on the mechanistic and clinical evidence for its effects.

Abstract
The effect of a multicomponent nutraceutical on cerebral ischemia/reperfusion injury in male Wistar rats was investigated. Animals were administered with the nutraceutical, Trévo™, for 7 days before 30 min of bilateral common carotid artery occlusion-induced cerebral ischemia and 24 hr of reperfusion. Behavioral assessment, biochemical estimations in the brain cortex, striatum, and hippocampus, and hippocampal histopathological evaluation were carried out after treatments. Results showed that ischemia/reperfusion-induced motor and cognitive deficits were abated in rats pretreated with Trévo™. Additionally, prophylaxis with Trévo™ blunted ischemia/reperfusion-induced redox stress, proinflammatory events, disturbances in neurotransmitter metabolism, mitochondrial dysfunction, and histoarchitectural aberrations in the discreet brain regions. In summary, supplementation with Trévo™ provided neuroprotection to rats against transient cerebral ischemia/reperfusion injury and could be explored as a promising approach in stroke prevention. PRACTICAL APPLICATIONS: There is a worldwide increase in the incidence of cerebral ischemia or stroke. Although an advanced health care system and effective control of risk factors have led to the declining incidence in developed nations, a definitive cure for stroke remains elusive and the situation is growing worse in developing nations. The results of the present study revealed that supplementation with Trévo™ ameliorated neurobehavioral, neurochemical, and histopathological consequences of brain ischemia/reperfusion injury and could, therefore, be beneficial in stroke prevention and management.

Abstract
Brain damage caused by cerebral ischaemia/reperfusion (I/R) can lead to handicapping. So, the present study aims to evaluate the prophylactic and therapeutic effects of geraniol in the form of intranasal polymeric mixed micelle (PMM) on the central nervous system in cerebral ischaemia/reperfusion (I/R) injury. A 32 factorial design was used to prepare and optimize geraniol PMM to investigate polymer and stabilizer different concentrations on particle size (PS) and percent entrapment efficiency (%EE). F3 possessing the highest desirability value (0.96), with a PS value of 32.46 ± 0.64 nm, EE of 97.85 ± 1.90%, and release efficiency of 59.66 ± 0.64%, was selected for further pharmacological and histopathological studies. In the prophylactic study, animals were classified into a sham-operated group, a positive control group for which I/R was done without treatment, and treated groups that received vehicle (plain micelles), geraniol oil, and geraniol micelles intranasally before and after I/R. In the therapeutic study, treated rats received geraniol oil and micelles after I/R. Evaluation of the effect of geraniol on behavior was done by activity cage and rotarod and the analgesic effect tested by hot plate. Anti-inflammatory activity was assessed by measuring interleukin β6, cyclooxygenase-2, hydrogen peroxide, and inducible nitric oxide synthase. Histopathogical examination of cerebral cortices was also done to confirm the results of a biochemical assay. Geraniol nanostructured polymeric mixed micelles showed an enhanced neuro-protective effect compared to geraniol oil, confirming that PMM via intranasal route could be an efficient approach for delivering geraniol directly to the brain through crossing the blood-brain barrier.

Abstract
Oxidative stress is strongly implicated in the pathogenesis of stroke. Strategies using antioxidants to improve neurological functions after stroke have, thus, gained significant attention. Ocimum basilicum L. is used traditionally to treat CNS disorders. Its antioxidant capacity is well established. Our laboratory has reported protective effects of pre-treatment with O. basilicum in experimental stroke, but its curative (post-treatment) effects in ischemic stroke have not been documented. Hence, the present study was aimed to evaluate the effect of O. basilicum leaf extract (OBLE) on functional outcomes following cerebral injury in mice. Cerebral injury was induced in the experimental animals by bilateral common carotid artery occlusion (BCCAO) followed by reperfusion. OBLE treatment (200 and 400 mg/kg; orally, once daily) was given for 7 days after BCCAO. Cognitive outcomes and sensorimotor disturbances were evaluated with Morris Water Maze, Elevated Plus Maze and neurological severity score, respectively. TTC (2,3,5-triphenyltetrazolium chloride) staining was used to measure cerebral infarct size. Thiobarbituric acid reactive substances, reduced glutathione levels and superoxide dismutase activity in mice brain homogenate were estimated to elucidate the neuroprotective mechanism of OBLE. Treatment with OBLE resulted in marked improvement in memory and motor coordination. OBLE also decreased cerebral infarct size and oxidative stress in mice. The extract was standardised with respect to total phenol content; an HPLC-PDA analysis showed the presence of eight phenolic acids in OBLE. It is concluded that treatment with OBLE improves functional outcomes after ischemic stroke and this may be developed as a neuroprotective drug.

Abstract
Leonurine has been reported to play an important role in ameliorating cognitive dysfunction, inhibiting ischemic stroke, and attenuating perihematomal edema and neuroinflammation in intracerebral hemorrhage. However, the exact mechanism and potential molecular targets of this effect remain unclear. Thus, in this study we investigated the neuroprotective effects of leonurine on hypoxia ischemia injury and explored the underlying mechanisms. An in vitro model of oxygen-glucose deprivation (OGD)-induced PC12 cells was established to mimic ischemic-like conditions. Cell viability, apoptosis, Cx36 and pCaMKII/CaMKII expression levels were evaluated after treatment with leonurine. The Cx36-selective antagonist mefloquine and CaMKII Inhibitor KN-93 were used to investigate the neuroprotective effect of leonurine on and the involvement of Cx36/CaMKII in this process. The results revealed that cell viability decreased and cell apoptosis and the protein expression of Cx36 and pCaMKII/CaMKII increased in the OGD-induced PC12 cells. Leonurine significantly increased cell viability and decreased cell apoptosis and the protein expression of Cx36 and pCaMKII/CaMKII in the OGD-induced PC12 cells. The specific inhibitor of Cx36 and CaMKII displayed similar protective effects. Moreover, the inhibition of Cx36 reduced pCaMKII levels and the ratio of pCaMKII/CaMKII in the OGD-induced PC12 cells, and vice versa. Taken together, these results suggest that leonurine might have a protective effect on OGD-induced PC12 cells through targeting the Cx36/CaMKII pathway. Thus, leonurine appears to have potential as a preventive or therapeutic drug against ischemic-induced neuronal injury.

Abstract
Abstract
Cerebral ischemia/reperfusion is known to induce the generation of reactive oxygen species and inflammatory responses. Numerous studies have demonstrated that naringin (NGIN) has anti-oxidant and anti-inflammatory properties. We previously reported that Citrus kawachiensis contains a large quantity of NGIN in its peel. In the present study, we orally (p.o.) administered dried peel powder of C. kawachiensis to mice of a transient global ischemia model and found in the hippocampus region that it 1) suppressed neuronal cell death, 2) reversed the reduction in the level of phosphorylated calcium-calmodulin-dependent protein kinase II, 3) had the tendency to reverse the reduction in the level of glutathione, and 4) blocked excessive activation of microglia and astrocytes. These results suggested that the dried peel powder of C. kawachiensis had a neuroprotective effect against ischemic brain via anti-oxidative and anti-inflammatory effects. We also showed that these effects of the dried peel powder were more powerful than those obtained with a comparable amount of NGIN alone.

Abstract
Ischemia-reperfusion injury (I/R injury) is a common feature of ischemic stroke which occurs when blood supply is restored after a period of ischemia. Although stroke is an important cause of death in the world, effective therapeutic strategies aiming at improving neurological outcomes in this disease are lacking. Various studies have suggested the involvement of different mechanisms in the pathogenesis of I/R injury in the nervous system. These mechanisms include oxidative stress, platelet adhesion and aggregation, leukocyte infiltration, complement activation, blood-brain barrier (BBB) disruption, and mitochondria-mediated mechanisms. Curcumin, an active ingredient of turmeric, can affect all these pathways and exert neuroprotective activity culminating in the amelioration of I/R injury in the nervous system. In this review, we discuss the protective effects of curcumin against I/R injury in the nervous system and highlight the studies that have linked biological functions of curcumin and I/R injury improvement.

Abstract
Cerebral ischemia reperfusion (IR) is associated with neuronal death, which leads to disability and cognitive decline. The pathomechanism occurs because ischemia is exacerbated during the reperfusion period. Neuronal damage susceptibility depends on the affected brain areas and the duration of ischemia. Prevention and supplementation to neurons may help them endure during IR and further benefit them in rehabilitation. We investigated the protective effect of p-coumaric acid (PC) on cerebral IR injuries in mice. We randomly divided 30 male ICR mice into 3 groups of Sham (received vehicle and not induced IR), Control-IR (received vehicle and induced IR) and PC-IR (received 100 mg/kg PC and induced IR). We orally administered vehicle or 100 mg/kg of p-coumaric acid for 2 weeks before inducing the cerebral IR injuries by using 30 min of a bilateral common carotid artery occlusion followed by a 45-min reperfusion. We induced the IR condition in the Control-IR and PC-IR groups but not the Sham group, and only the PC-IR group received p-coumaric acid. After IR induction, we sacrificed all the mice and collected their brain tissues to evaluate their oxidative statuses, whole brain infarctions and vulnerable neuronal deaths. We studied the whole-brain infarction volume by 2, 3, 5-triethyltetrazoliumchloride staining of sections. We performed a histological investigation of the vulnerable neuronal population in the dorsal hippocampus by staining brain sections with 0.1% cresyl violet. The results indicated that IR caused significant increases in calcium and malondialdehyde (MDA) levels, whole brain infarction volume and hippocampal neuronal death. Pretreatment with p-coumaric acid significantly reduced MDA levels, whole-brain infarction volume and hippocampal neuronal death together and increased catalase and superoxide dismutase activities. We conclude here that pretreating animals with p-coumaric acid can prevent IR-induced brain oxidative stress, infarction size and neuronal vulnerability to death in cerebral IR injuries.

Inhibition of miR-143 during ischemia cerebral injury protects neurones through recovery of the hexokinase 2-mediated glucose uptake. Biosci Rep 2017; 37:BSR20170216.

Abstract
Ischemic stroke, a major cause of death, is caused by occlusion of a blood vessel, resulting in significant reduction in regional cerebral blood flow. MiRNAs are a family of short noncoding RNAs (18–22 nts) and bind the 3′-UTR of their target genes to suppress the gene expression post-transcriptionally. In the present study, we report that miR-143 is down-regulated in rat neurones but highly expressed in astrocytes. In vivo middle cerebral artery occlusion (MCAO) and ex vivo oxygen-glucose deprivation (OGD) results showed that miR-143 was significantly induced by ischemia injury. Meanwhile, we observed suppression of glucose uptake and lactate product of rat brain and primary neurones after MCAO or OGD. The glycolysis enzymes hexokinase 2 (HK2), PKM2, and LDHA were inhibited by MCAO or OGD at protein and mRNA levels. In addition, overexpression of miR-143 significantly inhibited HK2 expression, glucose uptake, and lactate product. We report that HK2 is a direct target of miR-143. Importantly, restoration of HK2 in miR-143 overexpressing rat neurones recovered glucose uptake and lactate product. Our results demonstrated inhibition of miR-143 during OGD could protect rat neuronal cells from ischemic brain injury (IBI). In summary, the present study reveals a miRNA-mediated neuron protection during IBI, providing a new strategy for the development of therapeutic agents against IBI.
