The effectiveness and safety of noninvasive brain stimulation technology combined with speech training on aphasia after stroke: A systematic review and meta-analysis.

BACKGROUND: Although the effectiveness of noninvasive brain stimulation (NIBS) technology in assisting rehabilitation is widely recognized, its therapeutic efficacy in patients with poststroke aphasia (PSA) requires further validation. Here, we aimed to explore the efficacy and safety of the NIBS technique combined with speech training in PSA by traditional Meta-analysis and to compare the intervention effects of the 2 NIBS techniques by Network meta-analysis. METHODS: Randomized controlled trials of the NIBS technique combined with speech training for treating PSA in 9 databases, including Web of Science, PubMed, and CNKI, and 2 clinical trial registries were searched by computer. Literature screening was performed using EndNote X9 software, and data analysis and presentation of results were performed using RevMan 5.4.1 and Stata 17.0 software. RESULTS: Screening yielded 17 studies with 1013 patients with PSA. Meta-analysis showed that aphasia quotient scores were higher in the intervention group than in the control group [standardized mean difference (SMD) = 1.06, 95% confidence interval (CI) (0.63, 1.49), Z = 4.80, P < .00001]; Western aphasia battery scores on all 4 subscales were higher than those of the control group, the spontaneous language score is [SMD = 0.62, 95% CI (0.46, 0.78), Z = 7.52, P < .00001], the listening comprehension score is [SMD = 0.46, 95% CI (0.30, 0.62), Z = 5.62, P < .00001], the repetition score is [SMD = 1.14, 95% CI (0.59, 1.70), Z = 4.04, P < .0001], the naming score is [SMD = 1.06, 95% CI (0.79, 1.32), Z = 7.85, P < .00001]; The effective rate of the intervention group was higher than that of the control group [odd ratio = 4.19, 95% CI (2.39, 7.37), Z = 4.99, P < .00001]. The results of the Network meta-analysis showed that the best probability ranking of the 2 NIBS techniques combined with speech training in improving aphasia quotient scores was repetitive transcranial magnetic stimulation group (92.2%) > transcranial direct current stimulation group (55.7%). Regarding safety, it was not found that the NIBS technique combined with speech training to treat PSA increases the risk of adverse reactions. CONCLUSION: The NIBS technique combined with speech training can effectively improve the recovery of language function in PSA patients with minimal adverse effects, and the clinic can give priority to r TMS combined with speech training in treating PSA.

Efficacy of different rehabilitation therapies on post-stroke aphasia patients: A network meta-analysis.

BACKGROUND: Although several rehabilitation interventions are effective in post-stroke aphasia (PSA), the efficacy of different rehabilitation interventions compared to each other remains controversial. Here, we aimed to compare the effectiveness of varying rehabilitation interventions in PSA. METHODS: Randomized controlled trials on 8 kinds of rehabilitation interventions to improve speech function in patients with PSA were searched by computer from 10 databases, including PubMed, Web of Science, Cochrane, OVID, CINAHL, Embase, CNKI, WanFang, CBM, and VIP. The search scope was from the establishment of the database to August 2023. The literature screening, extraction of basic information, and quality assessment of the literature were conducted independently by 2 researchers. Network meta-analysis (NMA) was performed using Stata 17.0 software. RESULTS: Fifty-four studies involving 2688 patients with PSA were included. The results of NMA showed that: ① in terms of improving the severity of aphasia, the therapeutic effects of repetitive transcranial magnetic stimulation were the most significant; ② motor imagery therapy was the most effective in improving spontaneous speech, repetition, and naming ability; ③ in terms of improving listening comprehension ability, the therapeutic effects of mirror neuron therapy was the most significant. CONCLUSION: The 8 rehabilitation interventions have different focuses in improving the speech function of PSA patients, and the clinical therapists can select the optimal rehabilitation interventions in a targeted manner according to the results of this NMA and the patients' conditions and other relevant factors.

Banxia xiexin decoction prevents the development of gastric cancer.

BACKGROUND: In China banxia xiexin decoction (BXD) has been used in treating gastric cancer (GC) for thousands of years and BXD has a good role in reversing GC histopathology, but its chemical composition and action mechanism are still unknown. AIM: To investigate the mechanism of action of BXD against GC based on transcriptomics, network pharmacology, in vivo and in vitro experiments. METHODS: The transplanted tumor model was prepared, and the nude mouse were pathologically examined after administration, and hematoxylin-eosin staining was performed. The active ingredients of BXD were quality controlled and identified using ultra-performance liquid chromatography tandem quadrupole electrostatic field orbitrap mass spectrometry (UPLC-Q-Orbitrap MS/MS), and traditional Chinese medicines systems pharmacology platform, drug bank and the Swiss target prediction platform to predict the relevant targets, the differentially expressed genes (DEGs) of GC were screened by RNA-seq sequencing, and the overlapping targets were analyzed to obtain the key targets and pathways. Cell Counting Kit-8, apoptosis assay, cell migration and Realtime fluorescence quantitative polymerase chain reaction were used for in vitro experiments. RESULTS: All dosing groups inhibited the growth of transplanted tumors in laboratory-bred strain nude, with the capecitabine group and the BXD medium-dose group being the best. A total of 29 compounds and 859 potential targets in BXD were identified by UPLC-Q-Orbitrap MS/MS and network pharmacology, RNA-seq sequencing found 4767 GC DEGs, which were combined with network pharmacology and analyzed 246 potential therapeutic targets were obtained and pathway results showed that BXD may against GC through the Phosphoinositide 3-kinase (PI3K)/protein kinase B (AKt) signaling pathway. In vitro cellular experiments confirmed that BXD-containing serum and LY294002 could inhibit the proliferation of GC cells, promote apoptosis, and inhibit the migration of GC cells by decreasing the expression of EGFR, PIK3CA, IL6, BCL2 and AKT1 in the PI3K-Akt pathway in MGC-803 expression. CONCLUSION: BXD has the effect of inhibiting tumor growth rate and delaying the development of GC. Its mechanism of action may be related to the regulation of PI3K-Akt signaling pathway.

Curcumin's mechanism of action against ischemic stroke: A network pharmacology and molecular dynamics study.

Ischemic stroke (IS) is one of the major global causes of death and disability. Because blood clots block the neural arteries provoking ischemia and hypoxia in the brain tissue, IS results in irreversible neurological damage. Available IS treatments are currently limited. Curcumin has gained attention for many beneficial effects after IS, including neuroprotective and anti-inflammatory; however, its precise mechanism of action should be further explored. With network pharmacology, molecular docking, and molecular dynamics (MD), this study aimed to comprehensively and systematically investigate the potential targets and molecular mechanisms of curcumin on IS. We screened 1096 IS-related genes, 234 potential targets of curcumin, and 97 intersection targets. KEGG and GO enrichment analyses were performed on these intersecting targets. The findings showed that the treatment of IS using curcumin is via influencing 177 potential signaling pathways (AGE-RAGE signaling pathway, p53 signaling pathway, necroptosis, etc.) and numerous biological processes (the regulation of neuronal death, inflammatory response, etc.), and the AGE-RAGE signaling pathway had the largest degree of enrichment, indicating that it may be the core pathway. We also constructed a protein-protein interaction network and a component-target-pathway network using network pharmacology. From these, five key targets were screened: NFKB1, TP53, AKT1, STAT3, and TNF. To predict the binding conformation and intermolecular affinities of the key targets and compounds, molecular docking was used, whose results indicated that curcumin exhibited strong binding activity to the key targets. Moreover, 100 ns MD simulations further confirmed the docking findings and showed that the curcumin-protein complex could be in a stable state. In conclusion, curcumin affects multiple targets and pathways to inhibit various important pathogenic mechanisms of IS, including oxidative stress, neuronal death, and inflammatory responses. This study offers fresh perspectives on the transformation of curcumin to clinical settings and the development of IS therapeutic agents.

Deep muscle stimulator in the treatment of post-stroke spasticity: A protocol for systematic review and meta-analysis.

BACKGROUND: Spasticity is one of the most common complications and sequelae of stroke, with the main clinical manifestations being increased muscle tension, pain, stiffness, and other disorders. It not only increases the length of hospitalization and medical costs but also affects the quality of daily life and the stress of returning to society, increasing the burden on patients and their families. At present, 2 driver types of deep muscle stimulator (DMS) have been used in the clinical treatment of post-stroke spasticity (PSS) with good clinical results, but there is no evidence of clinical efficacy and safety. Therefore, this study aims to integrate direct and indirect comparative clinical evidence through a systematic review and network meta-analysis (NMA). According to the data, different driver types for DMS with the same body of evidence will be collected, analyzed, and sequenced in a quantitative and comprehensive manner and then screened for the optimal driver type of DMS device for PSS treatment. The study also aims to provide reference value and an evidence-based theoretical basis for the clinical optimization of DMS equipment selection. METHODS: A comprehensive retrieval of China National Knowledge Infrastructure, Chinese scientific journal database, China biological feature database, Wanfang Chinese databases and the Cochrane Library, PubMed, Web of Science, and Embase foreign databases will be conducted. Randomized controlled trials of these 2 driver types of DMS devices combined with conventional rehabilitation training of PSS will be searched and published. The retrieval time is from the establishment of the database to December 20, 2022. The 2 first authors will screen references that meet the inclusion criteria, independently extract data according to predesigned rules, and assess the quality of the included studies and the risk of bias according to the Cochrane 5.1 Handbook criteria. R programming and Aggregate Data Drug Information System software will be used to perform a combined NMA of the data and to evaluate the probability of ranking for all interventions. RESULTS: The NMA and probability ranking will determine the best driver type of DMS device for PSS. CONCLUSION: This study will offer a comprehensive evidence-based approach to DMS therapy and assist doctors, PSS patients, and decision-makers in selecting a more efficient, secure, and cost-effective treatment option.

Exploring the molecular mechanism of Nux Vomica in treating ischemic stroke using network pharmacology and molecular docking methods.

BACKGROUND: Nux Vomica (NV) has the effects of dredging collaterals, relieving pain, dispersing knots, and detumescence, and has a verified effect in treating ischemic stroke (IS), but its molecular mechanism for treating IS remains unclear. In this study, network pharmacology and molecular docking methods were adopted to explore the pharmacological mechanism of NV in treating IS. METHODS: The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and the HERB database were searched to screen the active components and targets of NV. IS disease targets were retrieved from the DisGeNET, DrugBank, GeneCards, and Therapeutic Target Database. Venn diagram and intersection targets were obtained from the Venny website. Subsequently, the STRING database was employed to analyze the interrelationship of the intersection targets. Metascape database was used for Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of intersection targets. Furthermore, Cytoscape was employed to plot a drug-component-target network, and other networks, and molecular docking method was adopted to predict the effective components and targets of NV for treating IS. RESULTS: A total of 14 active compounds and 59 targets of NV were screened, of which 35 targets were related to IS. Stigmasterol, brucine, isobrucine, isostrychnine N-oxide (I), (S)-stylopine, icaride A, and (2R)-5,7-dihydroxy-2-(4-hydroxyphenyl)chroman-4-one were the main active ingredients, and SLC6A4, NR3C1, SLC6A3, HTR3A, CHRNA7, MAOA, PTGS2, ESR1, catalase (CAT), ADRB2, and AR were the core targets. Molecular docking shows that these compounds bind well to the core targets. In addition, the treatment of IS by NV may mainly involve salivary secretion, serotonergic synapse, calcium signaling pathway, cGMP-PKG signaling pathway, and neuroactive ligand-receptor interaction. CONCLUSIONS: This study revealed that NV exerts its therapeutic effect on IS through multi-component, multi-target, and multi-pathway, which provides a basis for clinical treatment of IS.

Understanding the molecular mechanism of Ginkgo Folium-Forsythiae Fructus for cerebral atherosclerosis treatment using network pharmacology and molecular docking.

BACKGROUND: Cerebral atherosclerosis (CA) is a chronic disease caused by multiple infarcts and atrophy causing nerve degenerative syndrome. Ginkgo Folium (GF) and Forsythiae Fructus (FF) have shown positive effects on vascular protection, but their relationship with CA is unclear. This study aimed to identify the potential CA targets and mechanisms of action of GF-FF, using network pharmacology. OBJECTIVE: This study used network pharmacology and molecular docking to examine the potential targets and pharmacological mechanism of GF-FF on CA. METHODS: Using the traditional Chinese medicine systems pharmacology database and analysis platform, components were screened and corresponding targets were predicted using boundary values and Swiss Target Prediction. Using Cytoscape 3.8.0, a network was established between GF-FF components and CA targets. We extracted disease genes and constructed a network of targets based on the protein-protein interaction networks functional enrichment analysis database. Using Metascape, the Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes of the enriched targets were determined. AutoDock Vina was used to perform molecular docking. RESULTS: Twenty-three active ingredients of GF-FF were confirmed to treat CA, covering 109 targets, of which 48 were CA-related. Luteolin, bicuculline, sesamin, kaempferol, quercetin, and ginkgolide B were the vital active compounds, and EGFR, CYP2E1, CREB1, CYP19A1, PTGS2, PPARG, PPARA, ESR1, MMP9, MAPK14, MAPK8, and PLG were the major targets. The molecular docking showed that these compounds and targets exhibited good intercalation. These 48 protein targets produced effects on CA by modulating pathways such as "apoptosis-multiple species," "IL-17 signaling pathway," and "relaxin signaling pathway." CONCLUSIONS: As predicted by network pharmacology, GF-FF exerts anti-tumor effects through multiple components and targets for treatment of CA, providing new clinical ideas for CA treatment.

BACKGROUND: Ginkgo biloba L. leaves (GBLs) play a substantial role in the treatment of vascular dementia (VD); however, the underlying mechanisms of action are unclear. OBJECTIVE: This study was conducted to investigate the mechanisms of action of GBLs in the treatment of VD through network pharmacology, molecular docking, and molecular dynamics simulations. METHODS: The active ingredients and related targets of GBLs were screened using the traditional Chinese medicine systems pharmacology, Swiss Target Prediction and GeneCards databases, and the VD-related targets were screened using the OMIM, DrugBank, GeneCards, and DisGeNET databases, and the potential targets were identified using a Venn diagram. We used Cytoscape 3.8.0 software and the STRING platform to construct traditional Chinese medicine-active ingredient-potential target and protein-protein interaction networks, respectively. After gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis of potential targets using the DAVID platform, the binding affinity between key active ingredients and targets was analyzed by molecular docking, and finally, the top 3 proteins-ligand pairs with the best binding were simulated by molecular dynamics to verify the molecular docking results. RESULTS: A total of 27 active ingredients of GBLs were screened and 274 potential targets involved in the treatment of VD were identified. Quercetin, luteolin, kaempferol, and ginkgolide B were the core ingredients for treatment, and AKT1, TNF, IL6, VEGFA, IL1B, TP53, CASP3, SRC, EGFR, JUN, and EGFR were the main targets of action. The main biological processes involved apoptosis, inflammatory response, cell migration, lipopolysaccharide response, hypoxia response, and aging. PI3K/Akt appeared to be a key signaling pathway for GBLs in the treatment of VD. Molecular docking displayed strong binding affinity between the active ingredients and the targets. Molecular dynamics simulation results further verified the stability of their interactions. CONCLUSION SUBSECTIONS: This study revealed the potential molecular mechanisms involved in the treatment of VD by GBLs using multi-ingredient, multi-target, and multi-pathway interactions, providing a theoretical basis for the clinical treatment and lead drug development of VD.

Pain intensity and quality of daily life are outcome indicators. Stata 17.0 and ADDIS 1.16.8 software will be used for pairwise meta-analysis and network analysis to evaluate the effectiveness of rTMS and the ranking probability of all protocols. The recommended grading assessment, development, and evaluation will be used to assess the overall quality of the evidence. RESULTS: The meta-analysis and probability ranking of the network determined the best TMS protocol for fibromyalgia. CONCLUSION: This study will provide systematic support of evidence-based medicine for TMS in fibromyalgia, integrate the results of direct and indirect comparisons of the efficacy of different rTMS protocol, and provide the best one.

Exploration of potential targets and mechanisms of Naringenin in treating autism spectrum disorder via network pharmacology and molecular docking.

Naringenin (NR) is a kind of flavonoid which plays a great role in the treatment of autism spectrum disorder (ASD). However, the underlying mechanism of NR in treating ASD still remains unclear. This study used network pharmacology and molecular docking to examine the potential targets and pharmacological mechanism of NR on ASD. Targets related to NR were screened from Traditional Chinese Medicine System Pharmacology Database and Analysis Platform (TCMSP), Encyclopedia of Traditional Chinese Medicine Database (ETCM), Traditional Chinese Medicine Integrated Database (TCMID), PharmaMapper database, and targets related to ASD were screened from Online Mendelian Inheritance In Man (OMIM), Disgenet, GeneCards, Therapeutic Target Database (TTD), Drugbank, and ETCM. Screened of the intersected gene targets. Then, we used the protein-protein interaction (PPI) networks to construct a PPI network and used Network Analyzer plug-in to perform topological analysis to screen out the core target. We used Metascape platform to perform gene ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and used Chem draw, Pymol, AutoDock 1.5.6 software for molecular docking verification with core targets. A total of 149 targets of NR and 1594 potential targets of ASD were screened, and 43 intersected targets and 8 key targets were obtained and screened. A total of 176 GO items were obtained by GO enrichment analysis (P < .05), 153 entries on biological process (BP), 12 entries on BP and 11entries on cell composition (CC) were included. A total of 100 signaling pathways were obtained by KEGG pathway enrichment screening (P < .05).The pathways that are closely related to the pathogenesis of ASD are estrogen signaling, thyroid hormone signaling pathway, prolactin signaling pathway, and endocrine resistance pathway. Molecular docking results showed that NR had the best docking activity with the core target CASP3, and had good binding ability with AKT1, ESR1, ACTB and MAPK3. Taken together, our findings support that NR exerts therapeutic effects on ASD with multi-target, and multi-pathway characteristics, which provides a preliminary theoretical basis for clinical trials. The mechanism of anti-oxidative stress response, anti-apoptosis, regulation of cell growth and metabolism, anti-inflammatory, balance hormone levels may be important for the therapeutic effect.
