JOURNAL OF ETHNOPHARMACOLOGY 2024; 322:117583. [PMID: 38122912 DOI: 10.1016/j.jep.2023.117583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Revised: 11/20/2023] [Accepted: 12/11/2023] [Indexed: 12/23/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Subarachnoid hemorrhage (SAH) triggers a cascade of events that lead to early brain injury (EBI), which contributes to poor outcomes and appears within 3 days after SAH initiation. EBI involves multiple process including neuronal death, blood-brain barrier (BBB) injury and inflammation response. Microglia are cluster of immune cells originating in the brain which respond to SAH by changing their states and releasing inflammatory molecules through various signaling pathways. M0, M1, M2 are three states of microglia represent resting state, promoting inflammation state, and anti-inflammation state respectively, which can be modulated by pharmacological strategies. AIM OF THE STUDY After identified potential active ingredients and targets of Sanhua Decoction (SHD) for SAH, we selected aloe-emodin (AE) as a potential ingredient modulating microglia activation states. MATERIALS AND METHODS Molecular mechanisms, targets and pathways of SHD were reveal by network pharmacology technique. The effects of AE on SAH were evaluated in vivo by assessing neurological deficits, neuronal apoptosis and BBB integrity in a mouse SAH model. Furthermore, BV-2 cells were used to examine the effects of AE on microglial polarization. The influence of AE on microglia transformation was measured by Iba-1, TNF-α, CD68, Arg-1 and CD206 staining. The signal pathways of neuronal apoptosis and microglia polarization was measured by Western blot. RESULTS Network pharmacology identified potential active ingredients and targets of SHD for SAH. And AE is one of the active ingredients. We also confirmed that AE via NF-κB and PKA/CREB pathway inhibited the microglia activation and promoted transformation from M1 phenotype to M2 at EBI stage after SAH. CONCLUSIONS AE, as one ingredient of SHD, can alleviate the inflammatory response and protecting neurons from SAH-induced injury. AE has potential value for treating SAH-induced nerve injury and is expected to be applied in clinical practice.

Abstract
Neurological disorders are a major group of non-communicable diseases affecting quality of life. Non-Coding RNAs (ncRNAs) have an important role in the etiology of neurological disorders. In studies on the genesis of neurological diseases, aquaporin 4 (AQP4) expression and activity have both been linked to ncRNAs. The upregulation or downregulation of several ncRNAs leads to neurological disorder progression by targeting AQP4. The role of ncRNAs and AQP4 in neurological disorders is discussed in this review.

Abstract
Both thrombolytic and endovascular therapies are optimal treatment options for patients with acute ischemic stroke, but only less than half of these patients can benefit from these treatments. Traditional Chinese medicine has a long history of successfully managing ischemic stroke using both herbal and physical therapeutics. Among herbal recipes, Sanhua decoction (SHD) is one of the classical prescriptions for ischemic stroke. The present review aimed to summarize evidence from both clinical and basic research to demonstrate its efficacy in managing ischemic stroke and the potential mechanisms underlying its therapeutic effects, which will provide evidence on the therapeutic effect of this herbal recipe and guide future studies on this recipe. SHD is composed of four herbs, Rheum palmatum L. [Polygonaceae], Magnolia officinalis Rehder & E.H.Wilson [Magnoliaceae], Citrus × aurantium L. [Rutaceae], Hansenia weberbaueriana (Fedde ex H.Wolff) Pimenov & Kljuykov [Apiaceae]. We found that the majority of clinical studies on SHD are case reports and they showed positive therapeutic effect of SHD on both acute and chronic ischemic stroke. There are over 40 bioactive compounds identified in SHD, but few experimental studies have examined their individual molecular mechanisms. As an extract of SHD, it improves neurological functions through suppressing inflammation, protecting the blood brain barrier from degradation, restoring the number of neural stem cells, inhibiting apoptosis and brain edema, scavenging oxygen free radicals, and regulating the brain-gut axis. These will lay the theoretical foundation for future studies on this prescription and its clinical application. Future research may need to confirm its clinical efficacy in large-scale clinical trials and to disentangle its bioactive compounds and their potential mechanisms.

Abstract
CONTEXT Stroke is an illness with high morbidity, disability and mortality that presents a major clinical challenge. Sanhua decoction (SHD) has been widely used to treat ischaemic stroke in the clinic. However, the potential mechanism of SHD remains unknown. OBJECTIVE To elucidate the multitarget mechanism of SHD in ischaemic stroke through network pharmacology and bioinformatics analyses. MATERIALS AND METHODS Network pharmacology and experimental validation approach was used to investigate the bioactive ingredients, critical targets and potential mechanisms of SHD against ischaemic stroke. Four herbal names of SHD, 'ischemic stroke' or 'stroke' was used as a keyword to search the relevant databases. SH-SY5Y cells were treated with various concentrations of SHD (12.5, 25, 50 or 100 μg/mL) for 4 h, exposed to oxygen and glucose deprivation (OGD) for 1 h, then reoxygenation for 24 h. The cell viability was detected by MTT, the lactate dehydrogenase (LDH) was evaluated by ELISA, and protein expression was detected by western blots. RESULTS SHD treatment increased the survival rate from 65.9 ± 4.3 to 85.56 ± 5.7%. The median effective dose (ED50) was 47.1 μg/mL, the LDH decreased from 288.0 ± 12.0 to 122.8 ± 9.1 U/L and the cell apoptosis rate decreased from 33.6 ± 1.8 to 16.3 ± 1.2%. Western blot analysis revealed that SHD increased the levels of p-PI3k, p-Akt and p-CREB1, and decreased the expression of TNF-α and IL-6. DISCUSSION AND CONCLUSIONS This study suggests that SHD protects against cerebral ischaemic injury via regulation of the PI3K/Akt/CREB1 and TNF pathways.

Abstract
BACKGROUND Traumatic brain injury (TBI) is a common clinical condition caused by external force. Aquaporin-4 (AQP4) in astrocytes participates in the generation of cell swelling in TBI. METHODS This research explored the effect of AQP4 gene silencing in a TBI rat model. A hydraulic craniocerebral trauma instrument was employed for establishing the TBI rat model. AQP4 expression in the brain was inhibited by the injection of AQP4 shRNA-lentiviral vector. The expression of relative genes was evaluated by Western blot and qRT-PCR. Neuronal apoptosis was analyzed by TUNEL assay. RESULTS AQP4 shRNA treatment inhibited AQP4 expression in the brain of rats with TBI. AQP4 shRNA alleviated TBI-induced brain edema and neurological deficit in rats. Neuronal apoptosis and astrocyte activation in TBI rats were reduced by AQP4 silencing. CONCLUSION This research demonstrated that AQP4 shRNA-induced silencing of AQP4 in the TBI rat model reduced the expression of AQP4 and GFAP, alleviated brain edema, neurological deficit, neuronal apoptosis and inhibited astrocyte activation.

Abstract
Objective. The medical record of Chinese medicine is a miniature of the theoretical system of traditional Chinese medicine (TCM), with a time-honored history in a real-world setting and a firm place in medicine. In modern times, people have emphasized the value and standardization of TCM cases. The aim of this study was to explore the historical origins and developments of TCM case records. Methods. A chronological narrative style was used to divide the development history of TCM case records into early (1600 BC–220 AD), middle (220–1911 AD), and modern periods (1912–till now). The historical context of the origin and development of TCM case records was analyzed through the evolution of the format and content of the case recording files with the specific documents and distinctive cases. Results. From the early to middle period, the development of TCM case record had experienced four periods: the budding, blossoming, maturity, and heyday. In modern times, they presented the following characteristics: A, the establishment and development of the discipline of TCM medical records; B, the standardization of the writing format of TCM medical records; C, a large number of books concentrating on recording and studying TCM medical records, especially those of prestigious veteran TCM doctors; D, the proliferation of TCM case reports published in journals; E, the establishment of TCM medical records databases and application platforms integrating computer programs and artificial intelligence; F, many reporting guidelines have been developed in order to improve the reporting quality of case report in TCM. Conclusions. The study analyzed and illustrated the characteristics of TCM case records of different dynasties in terms of writing content and format. TCM case record is a relatively young discipline in spite of its ancient origins. TCM case records still have far-reaching significance for the inheritance and development of TCM theory and clinical experience. From the wisdom of history, its positive impact has just been revalued to be validated and it will continue to develop.

Abstract
Objective Stroke is a common and frequently occurring disease of the central nervous system, which is characterized by high mortality and a high disability rate. Moxibustion is a common method for treating stroke in traditional Chinese medicine, but its neuroprotective mechanism is unknown. N-Methyl-D-Aspartate Receptor Subunit 2B (NR2B) plays an important role in neuronal apoptosis. The objective of this study was to explore the mechanisms underlying the neuroprotective effect of moxibustion on cerebral ischemia/reperfusion (I/R) injury based on NR2B. Methods Sprague-Dawley rats were randomly divided into 5 groups: the control group, I/R group, I/R + moxibustion group, I/R + Ro25-6981 (NR2B antagonist) group, and I/R + Ro25-6981 + moxibustion group. The cerebral ischemia/reperfusion model was induced by middle cerebral artery occlusion. Before the establishment of the model, the Ro25-6981 group received intraperitoneal injections of Ro25-6981, the moxibustion group received moxibustion, and the Ro25-6981 + moxibustion group received both interventions. The neurological dysfunction was evaluated by a neurological deficiency score (NDS). The infarct volume was examined by TTC (2,3,5-triphenyltetrazolium chloride) staining. The apoptosis rate of cerebral cells in the ischemic area was examined by TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling) staining, and the expression of Bcl-2, Bax, and caspase-3 was observed by western blot. NR2B and JNK were also observed by western blot. Results Compared with the I/R group, moxibustion significantly decreased the neurological deficiency score (P < 0.05) and the infarct rate (P < 0.01) in I/R rats which were similar to those in the Ro25-6981 group. After moxibustion treatment, there was a significant decrease in the apoptosis rate (P < 0.001) and the protein expression levels of Bax, caspase-3, and JNK (P < 0.001) and an increase in the expression of Bcl-2 (P < 0.01). Compared with the I/R group, moxibustion downregulated the expression of NR2B and decreased the activity of NR2B in the cerebral ischemia area (P < 0.001). Conclusions Moxibustion can improve neurological dysfunction and decrease infarction area and neuronal apoptosis caused by cerebral ischemia/reperfusion in rats. Its neuroprotective mechanism may be related to downregulating the expression of NR2B.

Abstract
Due to its complex pathogenesis and lack of effective therapeutic methods, Alzheimer's disease (AD) has become a severe public health problem worldwide. Recent studies have discovered the function of central nervous system lymphatic drainage, which provides a new strategy for the treatment of AD. Chinese herbal medicine (CHM) has been considered as a cure for AD for hundreds of years in China, and its effect on scavenging β-amyloid protein in the brain of AD patients has been confirmed. In this review, the mechanism of central nervous system lymphatic drainage and the regulatory functions of CHM on correlation factors were briefly summarized. The advances in our understanding regarding the treatment of AD via regulating the central lymphatic system with CHM will promote the clinical application of CHM in AD patients and the discovery of new therapeutic drugs.

Abstract
Nuciferine is an aporphine alkaloid monomer that is extracted from the leaves of the lotus species Nymphaea caerulea and Nelumbo nucifera Gaertn. Nuciferine was reported to treat cerebrovascular diseases. However, the potential mechanism of the neuroprotective effects of nuciferine at the metabolomics level is still not unclear. The present research used neurological score, infarct volume, cerebral water content, and ultraperformance liquid chromatography to quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS)-based serum metabolomics to elucidate the anti-ischemic stroke effect and mechanisms of nuciferine. The results showed that nuciferine significantly improved neurological deficit scores and ameliorated cerebral edema and infarction. Multivariate data analysis methods were used to examine the differences in serum endogenous metabolism between groups, and the biomarkers of nuciferine on ischemic stroke were identified. Approximately 19 metabolites and 7 metabolic pathways associated with nuciferine on treatment of stroke were found, which indicated that nuciferine exerted a positive therapeutic action on cerebral ischemic by regulating metabolism. These results provided some data support for the study of anti-stroke effect of nuciferine from the perspective of metabolomics.

Abstract
Background: Ischemia stroke is the leading cause of death and long-term disability. Sanhua Decoction (SHD), a classic Chinese herbal prescription, has been used for ischemic stroke for about thousands of years. Here, we aim to investigate the neuroprotective effects of SHD on cerebral ischemia/reperfusion (CIR) injury rat models. Methods: The male Sprague-Dawley rats (body weight, 250-280 g; age, 7-8 weeks) were randomly divided into sham group, CIR group, and SHD group and were further divided into subgroups according to different time points at 6 h, 1, 3, 7, 14, 21, and 28 d, respectively. The SHD group received intragastric administration of SHD at 10 g kg-1 d-1. The focal CIR models were induced by middle cerebral artery occlusion according to Longa's method, while sham group had the same operation without suture insertion. Neurological deficit score (NDS) was evaluated using the Longa's scale. BrdU, doublecortin (DCX), and glial fibrillary acidic protein (GFAP) were used to label proliferation, migration, and differentiation of nerve cells before being observed by immunofluorescence. The expression of reelin, total tau (t-tau), and phosphorylated tau (p-tau) were evaluated by western blot and RT-qPCR. Results: SHD can significantly improve NDS at 1, 3, 7, and 14 d (p < 0.05), increase the number of BrdU positive and BrdU/DCX positive cells in subventricular zone at 3, 7, and 14 d (p < 0.05), upregulate BrdU/GFAP positive cells in the ischemic penumbra at 28 d after CIR (p < 0.05), and reduce p-tau level at 1, 3, 7, and 14 d (p < 0.05). There was no significant difference on reelin and t-tau level between three groups at each time points after CIR. Conclusions: SHD exerts neuroprotection probably by regulating p-tau level and promoting the proliferation, migration, and differentiation of endogenous neural stem cells, accompanying with neurobehavioral recovery.

Abstract
It is well-known that in ischemia-induced hypoxia, hypoxia-inducible factor -1α (HIF-1α) is critical in triggering expression of its downstream target genes to produce several products, such as erythropoietin (EPO), vascular endothelial growth factor (VEGF), nitric oxide synthesis (NOS), glucose transportor-1 (GLUT-1), insulin-like growth factor (IGF), which further promote erythropoiesis, angiogenesis, vasodilation and capitalization of glucose to overcome hypoxia. Meanwhile, as the factors with opposite effects on blood vessels, endothelin-1 (ET-1) and brain natriuretic peptide (BNP) also stand out strikingly in ischemic pathophysiology. To this day, several preconditioning manners have been used to induce tolerance to ischemia. During our research, exercise preconditioning was applied and it was demonstrated that HIF-1α triggered expression of ET-1 and BNP, which confirmed their downstream target genes for HIF-1α. And ET-1 may influcence expression of BNP to some degree but not the only factor which regulates BNP expression. Therefore, our findings suggest exercise preconditioning may provide protection to the ischemic brain tissue via HIF-1α which in turn increases expression of BNP to cause vasodilation in cooperation with some other factors, such as VEGF and EPO, to increase the blood flow in the ischemic area and then relieve the injuries induced by ischemia.

Abstract
Objective Ischemic stroke is a complex multifactorial disease caused by interactions among polygenetic, environmental, and lifestyle factors with limited effective treatments. Multi-herbal formulae have long been used for stroke through herbal compatibility in traditional Chinese medicine (TCM); however, there is still a lack of evidence due to their unimaginable complexity. Herbal pairs represent the simplest and basic features of multi-herbal formulae, which are of great significance in clarifying herbal compatibility. Here, we aim to investigate the neuroprotective effects of the herbal compatibility of Ginseng and Rhubarb on a cerebral ischemia/reperfusion (I/R) injury model of rats. Methods Male adult SD rats were randomly divided into a sham group, a normal saline (NS) group, a Ginseng group, a Rhubarb group, and a Ginseng + Rhubarb (GR) group, a Carbenoxolone [CBX, gap junction (GJ) specific inhibitor] group, and a GR + CBX group. Each group was further assigned into four subgroups according to ischemic time (6 h, 1 day, 3 days, and 7 days). The cerebral I/R injury model was established according to the modified Zea Longa method. The Neurological Deficiency Score (NDS) was assessed by the Zea-Longa scale; the cerebral infarction area was detected by TTC (2,3,5-triphenyltetrazolium chloride) staining; and the expression of connexin-43 (Cx43) and aquaporin-4 (AQP4) were detected based on an immunofluorescence technique and quantitative real-time-PCR. Results Compared to the I/R group, both the independent and combined use of Ginseng and Rhubarb can significantly improve NDS (P < 0.05), decrease the percentage of the cerebral infarction area around the infarction penumbra (P < 0.05) and down-regulate the expression of Cx43 and AQP4 after I/R injury (P < 0.05). The GR had more significant effects than that of Ginseng and Rhubarb (P < 0.05). Compared with the GR group, the GR + CBX group significantly improved in NDS (P < 0.05), and decreased the percentage of the cerebral infarction area (P < 0.05) and expression of Cx43 and AQP4 protein (P < 0.05). Conclusion The herbal compatibility of Ginseng and Rhubarb synergistically exerts neuroprotective function during acute cerebral I/R injury, mainly through reducing the expression of Cx43 and AQP4.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) and nocturnal enuresis (NE) are common clinical problems in children. OSA and NE are thought to be interrelated, but the exact pathophysiological mechanisms are not yet clear. This review aims to explain the possible pathogenesis of NE in children with OSA. DATE SOURCES We have retrieved all relevant original articles from Database that have been published so far, including the prevalence studies of NE and OSA in children, sleep characteristic studies that use polysomnography (PSG) to focus on children with NE, and studies on the relationship between OSA and NE. RESULTS Clinical studies have revealed that the risk of NE in children with OSA was increased compared with that of their healthy peers. This increased risk may be associated with sleep disorders, bladder instability, detrusor overactivity, nocturnal polyuria, endocrine and metabolic disorders, and inflammation. CONCLUSIONS Cardiopulmonary and renal reflex-induced neuroendocrine disorder may play an important role in the mechanism of NE in children with OSA, but this remains to be confirmed by animal studies. Other causes such as oxidative stress and inflammatory responses need to be further researched.

Abstract
Traumatic brain injury (TBI), an acute degenerative pathology of the central nervous system, is a leading cause of death and disability. As the glial scar is a mechanical barrier to nerve regeneration, inhibitory molecules in the forming scar and methods to overcome them have suggested molecular modification strategies to allow neuronal growth and functional regeneration. Herein, we aim to investigate the effects of aquaporin-4 (AQP4) gene silencing on the glial scar formation after TBI by establishing rat models. After modeling, TBI rats were transfected with AQP4 small hairpin RNA [shRNA] (AQP4 gene silencing by lentiviral vector-delivered shRNA) and empty vectors, respectively. Neurological functions of the rats were evaluated after TBI. The hematoxylin and eosin staining was conducted to observe histomorphological changes in rat brain tissues. The messenger RNA (mRNA) and protein expressions of glial fibrillary acidic protein (GFAP), vimentin, fibronectin, laminin, and AQP4 were measured by reverse transcription-quantitative polymerase chain reaction and Western blot analysis. The ratio of positive expression area was calculated, and the glial scar was observed by immunohistochemistry. At the 7th, 14th, and 28th days after TBI, TBI rats treated with AQP4 shRNA showed improved neurological function and lessened histomorphological changes. AQP4 gene silencing mediated by lentivirus decreased the mRNA and protein expressions of GFAP, vimentin, fibronectin, and laminin, the number of positive cells, the ratio of positive expression area, and the glial scar. Our study demonstrates that lentivirus-mediated AQP4 gene silencing could inhibit the formation of glial scar after TBI, which is beneficial to the recovery of neurological function.

Abstract
Acute ischemic stroke (AIS) generally causes neurological dysfunction and poses a serious threat to public health. Here, we aimed to assess the independent and combined effects of ginsenoside Rb1 (GRb1) and Emodin on neuroprotection through regulating Connexin 43 (Cx43) and Aquaporin 4 (AQP4) expression in cerebral ischemia/reperfusion (I/R) model rats. Adult male Sprague-Dawley (SD) rats were randomly divided into five groups: sham group, I/R group, Emodin group, GRb1 group and Emodin+GRb1 group. They were further allocated to four subgroups according to the 6h, 1d, 3d, and 7d time points except the sham group. Based on the modified Longa suture method, the focal cerebral I/R model was established by middle cerebral artery occlusion (MCAO). The neurological deficit scores (NDS), blood brain barrier (BBB) permeability and cerebral infarction area were assessed at each corresponding time point. Cx43 and AQP4 levels were assessed by Real-time PCR and Immunofluorescence. Compared with I/R group, both the independent and combined use of GRb1 and Emodin could alleviate NDS, reduce the BBB permeability, reduce the infarction area and down-regulate Cx43 and AQP4 expression at 6h, 1d, 3d, and 7d after I/R (P < 0.05). The Emodin+GRb1 group had more significant effects than Emodin group and GRb1 group (P < 0.05). In conclusion, the combination of Emodin and GRb1 exerts synergistically neuroprotective functions through regulating AQP4 and Cx43 after I/R.
