A neural prosthetic device is provided that includes one or more ion-selective membranes enabled by electrically-controlled local modulation of ion concentrations around a nerve so as to achieve different excitability states of the nerve for electrical stimulation or inhibition of nerve signal propagation. The local modulation is achieved by positioning the nerve in a bipolar perpendicular arrangement so as to modulate the ion concentrations of the one or more ion-selective membranes in situ to change the nerve excitability locally at the site of electrical stimulation or along the nerve for on-demand suppression of nerve propagation.

The invention discloses a treatment patch for acupoint application and belongs to the field of medicines. The treatment patch comprises a bottom liner layer and a cover liner layer. A base material is arranged between the bottom liner layer and the cover liner layer and is prepared from, by weight, far-infrared ceramic powder, acrylic pressure sensitive adhesives, stainless steel beads and drug extracts. Infrared rays with the wavelength being 8-15 microns generated by the far-infrared ceramic powder act on a human body and can penetrate the superficial portion of a human body, and the main biological function is the heat effect. The heat effect can reduce excitability of pain nerves and can also improve blood circulation, accelerate absorbing of morbid substances and inflammatory exudation substances, relieve irritation and pressing on nerve endings, and therefore pain can be relieved. The stainless steel beads stimulate acupoints so that local blood vessels can be expanded, blood flow is increased, blood circulation and microcirculation are improved, and therefore local tissue metabolism and nutrition can be improved, and the treatment patch has the anti-inflammatory detumescence, spasm relieving, pain easing and immunity regulation functions.

The invention discloses new application of sodium houttuyfonate in pharmacy, in particular to the application of the sodium houttuyfonate in preparing medicaments for preventing and treating myocardial hypertrophy and / or ventricular hypertrophy. The application is to prepare an in-vitro myocardial cell hypertrophyby adopting three methods of preparing an in-vivo animal model of myocardial hypertrophy and ventricular hypertrophy, culturing a myocardial cell in vitro and inducing epinephrine by isoproterenol, L-thyroxine and abdominal aorta banding. Experiment results prove that the sodium houttuyfonate can reduce the increase of left cardiac index and global cardiac index of a model animal, inhibit hypertrophy of an in-vitro myocardial cell, reduce the cAMP concentration of plasma, the content of Ang II and ET-1 of a myocardial tissue and the content of TNF-alpha and ALD of serum, and can reduce blood pressure and decrease heart rate. Experiment results suggest that the sodium houttuyfonate has the functions of resisting myocardial hypertrophy and ventricular hypertrophy, and the mechanism of the sodium houttuyfonate can be related to the inhibition of sympathetic activity, blockage of system activity of feritin-hypertensin-aldosterone, and effect of endocrine factors.

A method for treating Amyotrophic Lateral Sclerosis (ALS), also known as motor neuron disease (MND) or Lou Gehrig's disease, in a patient in need thereof comprises administering botulinum toxin to the patient. The botulinum toxin may be administered by subcutaneous or intradermal injection. The injection may be administered to and / or around the vicinity of a trigeminal nerve, a cervical nerve, a thoracic nerve, a lumbar nerve, and / or a sacral nerve of the patient. The administration of the botulinum toxin prevents an overproduction of glutamate, Substance P, and CGRP in a sensory system and thereby inhibits a migration of the glutamate, Substance P, and CGRP to the motor system, which otherwise would cause neuroexcitatory toxicity that results in the death of motor neurons.

The invention discloses a method for improving the protective effect of creatine on excitatory neurotoxicity, establishes an excitotoxic model of SH‑SY5Y cells treated with exogenous nitric oxide donor GSNO, and uses the model to prove that simple muscle Acid factor has a protective effect on neuroexcitotoxicity, but the effect is limited. In the SH‑SY5Y cell model treated with GSNO, the two neural creatine kinases CKBB and CKMT were nitrosylated, and the protein content and enzyme activity of the two were significantly reduced after modification; overexpression denitrosylation The modification enzyme GSNOR can significantly reduce the nitrosylation modification of CKBB and CKMT, and can significantly restore the content and activity of CKBB and CKMT. The present invention can significantly enhance the protective effect of creatine on excitotoxicity in combination with the denitrosylation modification scheme of neural creatine kinase.
