Effect of Inflammation on the Process of Stroke Rehabilitation and Poststroke Depression
Conclusions Stroke comprises ischemic stroke and ICH. The immuno-inflammatory process is involved in neural plasticity following events such as a hemorrhage or ischemic stroke. After ischemia, astrocytes, microglia, and MDMs play important roles during rehabilitation with the modulation of cytokines or chemokines, such as TNF-α and IL-1. Moreover, MiRNAs are also important posttranscriptional regulators in these glial mitochondrial responses to cerebral ischemia. ICH involves processes similar and different to those seen in ischemia, including neuronal injury, astrocytic and microglial/macrophage activation, and n...

Stroke Dysbiosis Index (SDI) in Gut Microbiome Are Associated With Brain Injury and Prognosis of Stroke
Conclusions: We developed an index to measure gut microbiota dysbiosis in stroke patients; this index was significantly correlated with patients' outcome and was causally related to outcome in a mouse model of stroke. Our model facilitates the potential clinical application of gut microbiota data in stroke and adds quantitative evidence linking the gut microbiota to stroke. Introduction Ischemic stroke imposes a heavy burden on society, with 24.9 million cases worldwide (1). Although intravenous thrombolysis and endovascular treatment greatly improve some patients' prognosis, the prognosis for most pa...

Effects of Xiaoshuan Enteric-Coated Capsule on White and Gray Matter Injury Evaluated by Diffusion Tensor Imaging in Ischemic Stroke.
This study was to investigate the effects of XSECC on white and gray matter injury in a rat model of ischemic stroke by diffusion tensor imaging (DTI) and histopathological analyses. The ischemia was induced by middle cerebral artery occlusion (MCAO). The cerebral blood flow measured by arterial spin labeling was improved by treatment with XSECC on the 3rd, 7th, 14th and 30th days after MCAO. Spatiotemporal white and gray matter changes in MCAO rats were examined with DTI-derived parameters (fractional anisotropy, FA; apparent diffusion coefficient, ADC; axial diffusivity, λ//; radial diffusivity, λ⊥). The increased FA...

Efficacy and safety of human-derived neural stem cell in patients with ischaemic stroke: study protocol for a randomised controlled trial
Introduction Stroke is the most common cause of neurological disability in adults worldwide. Neural stem cell (NSC) transplantation has shown promising results as a treatment for stroke in animal experiments. The pilot investigation of stem cells in stroke phase 1 and phase 2 trials showed that transplantation of the highest dose (20 million cells) was well tolerated. Preliminary clinical benefits have also been observed. However, the trials were open-label and had a small sample size. Furthermore, human NSCs (hNSCs) were intracerebrally implanted, and some serious adverse events were considered to be related to the surgic...

A study of the correlation between stroke and gut microbiota over the last 20years: a bibliometric analysis
ConclusionFindings suggest that in the next 10 years, the number of publications produced annually may increase significantly. Future research trends tend to concentrate on the mechanisms of stroke and gut microbiota, with the inflammation and immunological mechanisms, TMAO, and fecal transplantation as hotspots. And the relationship between these mechanisms and a particular cardiovascular illness may also be a future research trend.

Gut Flora Mediates the Rapid Tolerance of Electroacupuncture on Ischemic Stroke by Activating Melatonin Receptor through Regulating Indole-3-Propionic Acid
This study aimed to clarify the mechanisms of action of treatments of cerebral ischemic stroke from the perspective of gut microecology. We used a mouse model and cell cultures to investigate the effects of EA on the intestinal microflora in mice models of middle cerebral artery occlusion (MCAO) and the mechanisms underlying the antioxidant activities of metabolites. Fecal microbiota transplantation (FMT) was used to validate the roles of gut microbiota. Metabolomic analysis was performed to characterize the metabolic profile differences between the mice in the EA + MCAO and MCAO groups. Gavaging with feces relieved brain ...
