Kulamarva K, Shivakumar V, Chikkanna U, Ramakrishna KK, Bhargav H, Varambally S. Role of Ayurveda in the management of psychotic disorders: A systematic review of clinical evidence. J Ayurveda Integr Med 2023; 14:100720. [PMID: 37290315 PMCID: PMC10267528 DOI: 10.1016/j.jaim.2023.100720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 03/11/2023] [Accepted: 04/29/2023] [Indexed: 06/10/2023] Open
Abstract
BACKGROUND Despite advancements in the treatment of psychosis, many patients continue to experience persistent symptoms and relapses during antipsychotic treatment, particularly when they fail to adhere to prescribed medications. Ayurveda explains psychotic disorders as "Unmada" and describes various treatment protocols. Although these therapies and methods have been in practice for several years, systematic evidence has not been generated for the same. Thus, in the current review an attempt has been made to illustrate currently available clinical trials on Ayurveda management of psychosis. METHODS We identified 23 studies by literature search in PubMed Central, Cochrane Library and AYUSH Research portal. Out of these, 21 were retrieved after systematic deduplication. After excluding nine studies, 12 studies were included for review. RESULTS Total of 12 articles comprising 10 clinical trials and 2 case reports were reviewed. Most of the studies demonstrated significant improvement in psychopathology assessed through various symptom rating scales. DISCUSSION The role of Ayurveda, in the treatment of psychosis is least explored. Currently available studies on the effect of Ayurveda treatment on psychosis are very less in number to draw a valuable conclusion. Hence there is a large scope for conducting neurobiologically informed clinical research in the management of psychotic disorders using Ayurvedic approaches.

[PMID: 37049568 PMCID: PMC10097163 DOI: 10.3390/nu15071727] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 03/21/2023] [Accepted: 03/28/2023] [Indexed: 04/03/2023] Open
Abstract
Convolvulus pluricaulis (CP) is a common Indian herb, largely employed in Ayurvedic medicine and known for its neuroprotective and neuroinflammatory action. Its effectiveness against several pathologic/sub-pathologic conditions is widely accepted, but it is not yet completely chemically characterized. In recent years, several researchers have pointed out the involvement of CP and other Convolvulaceae in lipidic and glucidic metabolism, particularly in the control of hyperlipidaemia and diabetic conditions. In this scenario, the aim of the study was to chemically characterize the medium polarity part of the CP whole plant and its fractions and to shed light on their biological activity in adipocyte differentiation using the 3T3-L1 cell model. Our results demonstrated that the CP extract and fractions could upregulate the adipocyte differentiation through the modulation of the nuclear receptor PPARγ (Peroxisome Proliferator-Activated Receptor γ), broadly recognized as a key regulator of adipocyte differentiation, and the glucose transporter GLUT-4, which is fundamental for cellular glucose uptake and for metabolism control. CP also showed the ability to exert an anti-inflammatory effect, downregulating cytokines such as Rantes, MCP-1, KC, eotaxin, and GM-CSF, which are deeply involved in insulin resistance and glucose intolerance. Taken together, these data suggest that CP could exert a potential beneficial effect on glycemia and could be employed as an anti-diabetic adjuvant or, in any case, a means to better control glucose homeostasis.

Abstract
Cerebral ischemic stroke is characterized by acute ischemia in a certain part of the brain, which leads to brain cells necrosis, apoptosis, ferroptosis, pyroptosis, etc. At present, there are limited effective clinical treatments for cerebral ischemic stroke, and the recovery of cerebral blood circulation will lead to cerebral ischemia-reperfusion injury (CIRI). Cerebral ischemic stroke involves many pathological processes such as oxidative stress, inflammation, and mitochondrial dysfunction. Nuclear factor erythroid 2-related factor 2 (Nrf2), as one of the most critical antioxidant transcription factors in cells, can coordinate various cytoprotective factors to inhibit oxidative stress. Targeting Nrf2 is considered as a potential strategy to prevent and treat cerebral ischemia injury. During cerebral ischemia, Nrf2 participates in signaling pathways such as Keap1, PI3K/AKT, MAPK, NF-κB, and HO-1, and then alleviates cerebral ischemia injury or CIRI by inhibiting oxidative stress, anti-inflammation, maintaining mitochondrial homeostasis, protecting the blood-brain barrier, and inhibiting ferroptosis. In this review, we have discussed the structure of Nrf2, the mechanisms of Nrf2 in cerebral ischemic stroke, the related research on the treatment of cerebral ischemia through the Nrf2 signaling pathway in recent years, and expounded the important role and future potential of the Nrf2 pathway in cerebral ischemic stroke.

Protective Mechanisms of Nootropic Herb Shankhpushpi ( Convolvulus pluricaulis) against Dementia: Network Pharmacology and Computational Approach. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:1015310. [PMID: 36225186 PMCID: PMC9550454 DOI: 10.1155/2022/1015310] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Accepted: 07/28/2022] [Indexed: 11/28/2022]
Abstract
Convolvulus pluricaulis (CP), a Medhya Rasayana (nootropic) herb, is a major ingredient in Ayurvedic and Traditional Chinese formulae indicated for neurological conditions, namely, dementia, anxiety, depression, insanity, and epilepsy. Experimental evidence suggests various neuroactive potentials of CP such as memory-enhancing, neuroprotective, and antiepileptic. However, precise mechanisms underlying the neuropharmacological effects of CP remain unclear. The study, therefore, aimed at deciphering the molecular basis of neuroprotective effects of CP phytochemicals against the pathology of dementia disorders such as Alzheimer's (AD) and Parkinson's (PD) disease. The study exploited bioinformatics tools and resources, such as Cytoscape, DAVID (Database for annotation, visualization, and integrated discovery), NetworkAnalyst, and KEGG (Kyoto Encyclopedia of Genes and Genomes) database to investigate the interaction between CP compounds and molecular targets. An in silico analysis was also employed to screen druglike compounds and validate some selective interactions. ADME (absorption, distribution, metabolism, and excretion) analysis predicted a total of five druglike phytochemicals from CP constituents, namely, scopoletin, 4-hydroxycinnamic acid, kaempferol, quercetin, and ayapanin. In network analysis, these compounds were found to interact with some molecular targets such as prostaglandin G/H synthase 1 and 2 (PTGS1 and PTGS2), endothelial nitric oxide synthase (NOS3), insulin receptor (INSR), heme oxygenase 1 (HMOX1), acetylcholinesterase (ACHE), peroxisome proliferator-activated receptor-gamma (PPARG), and monoamine oxidase A and B (MAOA and MAOB) that are associated with neuronal growth, survival, and activity. Docking simulation further confirmed interaction patterns and binding affinity of selected CP compounds with those molecular targets. Notably, scopoletin showed the highest binding affinity with PTGS1, NOS3, PPARG, ACHE, MAOA, MAOB, and TRKB, quercetin with PTGS2, 4-hydroxycinnamic acid with INSR, and ayapanin with HMOX1. The findings indicate that scopoletin, kaempferol, quercetin, 4-hydroxycinnamic acid, and ayapanin are the main active constituents of CP which might account for its memory enhancement and neuroprotective effects and that target proteins such as PTGS1, PTGS2, NOS3, PPARG, ACHE, MAOA, MAOB, INSR, HMOX1, and TRKB could be druggable targets against dementia.

Abstract
Alzheimer's disease (AD) is a multi-faceted neurodegenerative disorder that leads to drastic cognitive impairments culminating in death. Pathologically, it is characterized by amyloid-β (Aβ) plaques, neurofibrillary tangles and neurodegeneration in brain. Complete cure of AD remains elusive to date. Available synthetic drugs only provide symptomatic reliefs targeting single molecule, hence, are unable to address the multi-factorial aspects in AD pathogenesis. It is imperative to develop combinatorial drugs that address the multiple molecular targets in AD. We show a unique polyherbal formulation of Brahmi, Mandukaparni, Shankhpushpi, Yastimadhu, Kokilaksha and Shunthi called 'Medha Plus' (MP), conventionally used for improving memory and reducing anxiety, was able to ameliorate cognitive deficits and associated pathological hallmarks of AD. Viability assays revealed that MP prevented Aβ-induced loss of neurites as well as neuronal apoptosis in cellular models. An array of behavioral studies showed that MP was able to recover AD-associated memory deficits in both Aβ-injected rats and 5XFAD mice. Immunohistochemical studies further revealed that MP treatment reduced Aβ depositshpi and decreased apoptotic cell death in the hippocampus. Enzymatic assays demonstrated anti-oxidative and anti-acetyl cholinesterase properties of MP especially in hippocampus of Aβ-injected rats. An underlying improvement in synaptic plasticity was observed with MP treatment in 5XFAD mice along with an increased expression of phospho-Akt at serine 473 indicating a role of PI3K/Akt signaling in correcting these synaptic deficits. Thus, our strong experiment-driven approach shows that MP is an incredible combinatorial drug that targets multiple molecular targets with exemplary neuroprotective properties and is proposed for clinical trial.

Abstract
Ischemic stroke (IS) is characterized by high recurrence and disability; however, its therapies are very limited. As one of the effective methods of treating acute attacks of IS, intravenous thrombolysis has a clear time window. Quercetin, a flavonoid widely found in vegetables and fruits, inhibits immune cells from secreting inflammatory cytokines, thereby reducing platelet aggregation and limiting inflammatory thrombosis. In pre-clinical studies, it has been shown to exhibit neuroprotective effects in patients with ischemic brain injury. However, its specific mechanism of action remains unknown. Therefore, this review aims to use published data to elucidate the potential value of quercetin in patients with ischemic brain injury. This article also reviews the plant sources, pharmacological effects, and metabolic processes of quercetin in vivo, thus focusing on its mechanism in inhibiting immune cell activation and inflammatory thrombosis as well as promoting neuroprotection against ischemic brain injury.

Abstract
Cerebral ischemic stroke is a major cause of adult morbidity and mortality worldwide. Several long non-coding RNAs (lncRNAs) have been reported to participate in cerebral ischemia/reperfusion injury (IRI). However, to the best of our knowledge, the role of lncRNA AK139328 in cerebral ischemic stroke remains poorly understood. The present study aimed to determine the expression and function of lncRNA AK139328 in the progression of IRI. PC12 cells were injured by oxygen glucose deprivation/reoxygenation (OGD/R) to establish an in vitro ischemic stroke model. An MTT assay was performed to determine cell viability. Reverse transcription-quantitative PCR was used to analyze the expression levels of AK139328 and Netrin-1 in blood samples from patients who had suffered a cerebral ischemic stroke and healthy individuals or OGD/R PC12 cells. ELISAs were used to determine the levels of inflammatory cytokines. In addition, oxidative stress levels and the levels of cell apoptosis were evaluated by reactive oxygen species (ROS) kits, flow cytometry and western blotting. Immunofluorescence staining was used for the detection of cell neurite outgrowth. The results of the present study revealed that AK139328 expression levels were upregulated in patients who had suffered a cerebral ischemic stroke and in PC12 cells following stimulation with OGD/R. The knockdown of AK139328 alleviated OGD/R-induced decreases in cell viability, downregulation in Netrin-1 expression and increases in inflammatory cytokines levels, including TNF-α, IL-1β and IL-6. Moreover, AK139328 silencing suppressed oxidative stress and cell apoptosis in OGD/R-treated PC12 cells. Furthermore, the expression levels of microtubule associated protein 2 and growth associated protein 43 in OGD/R-injured PC12 cells were upregulated following the knockdown of AK139328 expression. In conclusion, these findings suggested that the knockdown of AK139328 expression may protect PC12 cells against OGD/R injury by regulating inflammatory responses, oxidative stress and cell apoptosis. The data suggested a potential therapeutic target for the diagnosis and treatment of cerebral ischemic stroke.

Abstract
Quercetin, a bioactive secondary metabolite, holds incredible importance in terms of bioactivities, which has been proved by in vivo and in vitro studies. The treatment of cardiovascular and neurological diseases by quercetin has been extensively investigated over the past decade. Quercetin is present naturally in appreciable amounts in fresh produce (fruits and vegetables). However, today, corresponding to the growing population and global demand for fresh fruits and vegetables, a paradigm shift and focus is laid towards exploring industrial food wastes and/or byproducts as a new resource to obtain bioactive compounds such as quercetin. Based on the available research reports over the last decade, quercetin has been suggested as a reliable therapeutic candidate for either treating or alleviating health issues, mainly those of cardiovascular and neurological diseases. In the present review, we have summarized some of the critical findings and hypotheses of quercetin from the available databases foreseeing its future use as a potential therapeutic agent to treat cardiovascular and neurological diseases. It is anticipated that this review will be a potential reference material for future research activities to be undertaken on quercetin obtained from fresh produce as well as their respective processing wastes/byproducts that rely on the circular concept.

Abstract
Oxygen supply for ischemic brain tissue during stroke is critical to neuroprotection. Remote ischemic conditioning (RIC) treatment is effective for stroke. However, it is not known whether RIC can improve brain tissue oxygen supply. In current study, we employed a mouse model of stroke created by middle cerebral artery occlusion (MCAO) to investigate the effect of RIC on oxygen supply to the ischemic brain tissue using a hypoxyprobe system. Erythrocyte oxygen-carrying capacity and tissue oxygen exchange were assessed by measuring oxygenated hemoglobin and oxygen dissociation curve. We found that RIC significantly mitigated hypoxic signals and decreased neural cell death, thereby preserving neurological functions. The tissue oxygen exchange was markedly enhanced, along with the elevated hemoglobin P50 and right-shifted oxygen dissociation curve. Intriguingly, RIC markedly elevated 2,3-biphosphoglycerate (2,3-BPG) levels in erythrocyte, and the erythrocyte 2,3-BPG levels were highly negatively correlated with the hypoxia in the ischemic brain tissue. Further, adoptive transfusion of 2,3-BPG-rich erythrocytes prepared from RIC-treated mice significantly enhanced the oxygen supply to the ischemic tissue in MCAO mouse model. Collectively, RIC protects against ischemic stroke through improving oxygen supply to the ischemic brain tissue where the enhanced tissue oxygen delivery and exchange by RIC-induced 2,3-BPG-rich erythrocytes may play a role.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Peach kernel (taoren: TR) is the dried mature seed of peach, Prunus persica (L.) Batsch, which belongs to the Rosaceae family. Rhubarb (dahuang: DH) is the dried root and rhizome of rhubarb (Rheum palmatum L., Rheum officinale Baill., or Rheum tanguticum Maxim. ex Balf.). TR-DH (TD) is a traditional Chinese medicine herb pair that promotes blood circulation and removes blood stasis. In recent years, TD has shown definite benefits in the cardio-cerebrovascular system, but its specific mechanism is not very clear. AIM OF STUDY The purpose of this study was to explore the mechanism by which TD affects cerebral ischaemia/reperfusion (I/R) injury and to optimize the mixture ratio. METHODS The affected metabolic pathways in rat brain tissues after I/R were analysed by network pharmacology and verified with animal pharmacological experiments. RESULTS TD had a certain therapeutic effect on cerebral I/R injury. TD with a TR:DH ratio of 1:1 had the best therapeutic effect. Metabolic pathway analysis showed that the protective mechanism of TD against I/R injury involves mainly regulation of brain tissue ADORA2A protein levels and action on the arachidonic acid (AA) pathway. CONCLUSION TD can ameliorate cerebral I/R injury by regulating ADORA2A degradation in the AA metabolic pathway to attenuate AA metabolic dysfunction and the inflammatory response.
