Relationship between motor performance and cortical activity of older neurological disorder patients with dyskinesia using fNIRS: A systematic review.

Neurological disorders with dyskinesia would seriously affect older people's daily activities, which is not only associated with the degeneration or injury of the musculoskeletal or the nervous system but also associated with complex linkage between them. This study aims to review the relationship between motor performance and cortical activity of typical older neurological disorder patients with dyskinesia during walking and balance tasks.

Regulating autonomic nervous system homeostasis improves pulmonary function in rabbits with acute lung injury.

Background: This study aimed to investigate the effects of regulating autonomic nervous system (ANS) homeostasis by inhibiting sympathetic hyperactivity and/or enhancing parasympathetic activity on pulmonary inflammation and functional disturbance.

Methods: An animal model of acute lung injury (ALI) was established in rabbits by an intratracheal injection of hydrochloric acid (HCl) in rabbits. Animals in control groups were received saline or HCl only, and the others received both HCl and followed treatments: vagus nerve stimulation (VNS), intravenous injection of tetrahydroaminoacridine (THA), or stellate ganglion block (SGB).

Electroacupuncture brain protection during ischemic stroke: A role for the parasympathetic nervous system.

The demand for using parasympathetic activation for stroke therapy is unmet. In the current study, we investigated whether the neuroprotection provided by electroacupuncture (EA) in an experimental stroke model was associated with activation of the parasympathetic nervous system (PNS). The results showed that parasympathetic dysfunction (PD), performed as unilateral vagotomy combined with peripheral atropine, attenuated both the functional benefits of EA and its effects in improving cerebral perfusion, reducing infarct volume, and hindering apoptosis, neuronal and peripheral inflammation, and oxidative stress.

The effects of electroacupuncture treatment on the postoperative cognitive function in aged rats with acute myocardial ischemia-reperfusion.

Many literatures have proven that postoperative cognitive dysfunction (POCD) was very common in old patients after the injury of acute myocardial ischemia-reperfusion (AMIR) clinically such as the off-pump coronary artery bypass surgery (OPCAB) without definite mechanism; however, reports on the animal experiments were rarely seen. We hypothesized that AMIR could contribute to cognitive dysfunction, and this severe injury might be impeded by EA via hindering neuroinflammation and oxidative stress response as well as modulating the balance of the autonomic nervous system. The aged male Sprague Dawley rats were randomly assigned into three experimental groups: sham (sham operation), AMIR, and EA (electroacupunture treatment, acupoints GV20 and ST36+AMIR) groups.

Effects of Dexmedetomidine combined with Dezocine on cognition function and hippocampal microglia activation of rats.

Objective: This study aimed to investigate the effects of Dexmedetomidine combined with Dezocine on the cognition and hippocampal microglia activation of rats.

Methods: Laparotomy was successfully performed in 48 rats which were then divided into Dexmedetomidine+Dezocine group and Dezocine group. Rats in Dexmedetomidine+dezocine group were infused with Dexmedetomidine and dezocine via the tail vein after anesthesia; rats in Dezocine group were infused with dezocine via the tail vein.

Neuroprotective effects of therapeutic hypercapnia on spatial memory and sensorimotor impairment via anti-apoptotic mechanisms after focal cerebral ischemia/reperfusion.

A number of studies have demonstrated that therapeutic hypercapnia ameliorates neurological deficits and attenuates the histological damage of cerebral ischemia-reperfusion injury. However, the effects of therapeutic hypercapnia on impaired spatial memory have not been reported. Here we aimed to investigate the effects and mechanisms of therapeutic hypercapnia on spatial memory in a rat model of focal cerebral ischemia induced by middle cerebral artery occlusion/reperfusion (MCAO/R).

Effects of electro-acupuncture on endothelium-derived endothelin-1 and endothelial nitric oxide synthase of rats with hypoxia-induced pulmonary hypertension.

Pulmonary hypertension (PH) is characterized by elevated pulmonary artery pressure (PAP), pulmonary vascular remodeling and right ventricular hypertrophy, which are mainly due to endothelial dysfunction. Electro-acupuncture has shown beneficial effects on cardiovascular homeostasis, but little evidence has been obtained on pulmonary effects. The goal of the present study was to investigate whether electro-acupuncture on bladder-13 and -15 points can protect against chronic hypoxia-induced PH by regulating endothelium-derived endothelin (ET)-1 and endothelial nitric oxide synthase (eNOS).

Effects of mixture of lidocaine and ropivacaine at different concentrations on the central nervous system and cardiovascular toxicity in rats.

Background: Lidocaine and ropivacaine are often combined in clinical practice to obtain a rapid onset and a prolonged duration of action. However, the systemic toxicity of their mixture at different concentrations is unclear. This study aimed to compare the systemic toxicity of the mixture of ropivacaine and lidocaine at different concentrations when administered intravenously in rats.

{μ-6,6'-Dimeth-oxy-2,2'-[propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolato}trinitratocopper(II)erbium(III) acetone solvate.

In the title complex, [CuEr(C(19)H(20)N(2)O(4))(NO(3))(3)]·CH(3)COCH(3), the Cu(II) ion is coordinated in a square-planar environment by two O atoms and two N atoms of a Schiff base ligand. The Er(III) ion is bis-chelated by three nitrate ligands and coordinated by four O atoms of the Schiff base ligand in a slightly distorted bicapped square-anti-prismatic environment.
