Ischemic stroke(IS)is a severe cerebrovascular disease that seriously endangers human health.Gut microbiota plays a key role as an intermediate mediator in bidirectional regulation between the brain and the intestine.In recent years,trimethylamine N-oxide(TMAO)as a gut microbiota metabolite has received widespread attention in cardiovascular diseases.Elevated levels of TMAO may increase the risk of IS by affecting IS risk factors such as atherosclerosis,atrial fibrillation,hypertension,and type 2 diabetes.TMAO exacerbates neurological damage in IS patients,increases the risk of IS recurrence,and is an independent predictor of post-stroke cognitive impairment(PSCI)in patients.Current research suggests that the mechanisms of TMAO action include endothelial dysfunction,promoting of foam cell formation,influence on cholesterol metabolism,and enhancement of platelet reactivity.Lowering plasma TMAO levels through the rational use of traditional Chinese medicine,dietary management,vitamins,and probiotics can prevent and treat IS.

ObjectiveTo observe the recovery of proprioception of the affected ankle over time after lateral ankle sprain accepting routine rehabilitation. MethodsFrom June, 2020 to June, 2022, 18 patients with lateral ankle sprain in Kunshan Rehabilitation Hospital underwent routine rehabilitation for twelve weeks. They were measured active and passive position sense of bilateral ankles using an isokinetic dynamometer before treatment, and four, eight and twelve weeks after treatment, respectively. ResultsThe active presentation difference of affected ankle reduced after treatment (F = 22.533, P < 0.001), but it was more than that of the healthy ankle at the same time (t > 4.419, P < 0.001). No significant improvement was found in passive presentation difference of affected ankle after treatment (F = 1.175, P > 0.05), and it was not significantly different from those of the healthy ankle at the same time (|t| < 0.646, P > 0.05). ConclusionProprioception of affected ankle has been impaired after lateral ankle sprain, and it can be recovered after rehabilitation, but cannot achieve the healthy level even after three months of training. Passive position sense as an index of proprioception needs more researches.
