Methods and systems are provided for determining an increased likelihood of the occurrence of a cardiac arrhythmia, myocardial ischemia, congestive heart failure and other diseased conditions of the heart associated with elevated sympathetic neural discharges in a patient. The methods and systems comprise monitoring the sympathetic neural discharges of a patient from the stellate ganglia, the thoracic ganglia, or both, and detecting increases in the sympathetic neural discharges. The methods and systems may further comprise delivering therapy to the patient in response to a detected increase in the sympathetic neural discharge, such as delivering one or more pharmacological agents; stimulating myocardial hyperinnervation in the sinus node and right ventricle of the heart of the patient; and applying cardiac pacing, cardioversion or defibrillation shocks. Pharmacologic agents which may be used in connection with the delivery of include those which are known to exert anti-arrhythmic effect and anti-convulsant agents, such as phenytoin, carbamazepine, valproate, and phenobarbitone. Other pharmacologic agents may be used to treat impending myocardial ischemia and other diseased conditions of the heart associated with elevated sympathetic neural discharges.

A monomeric adhesive composition includes a stabilized polymerizable monomer, such as a 1,1-disubstituted monomer, including a cyanoacrylate, and a wound healing agent, wherein the wound healing agent is 5,5-disubstitutedhydantoin, including phenyloin; and a method for making said composition.

The invention aims at providing a preparation method of high-specificity phenytoin polyclonal antibodies and a phenytoin homogeneous enzyme immunoassay kit. The preparation method comprises the steps of preparing phenytoin specific polyclonal antibodies, preparing phenytoin conjugates labeled by glucose-6-phosphate dehydrogenase, and preparing calibration solution. The specificity of the phenytoin polyclonal antibodies is high, the valence is high, the phenytoin polyclonal antibodies almost do not crossly react with tested thirty-two kinds of common drugs and compounds during drug cross reaction testing, and the phenytoin polyclonal antibodies are suitable for the clinical detection of blood concentration of phenytoin. The sensitivity of the phenytoin drug concentration homogeneous enzyme immunoassay kit is high, samples with concentration being 10ng / ml can be accurately detected and the effective detection range of phenytoin drug concentration is 20ng / ml to 40mug / ml. The kit provided by the invention has the advantages of high accuracy, high recovery rate above 90 percent, convenience, rapidness, low cost, high sensitivity and full automation.

The invention belongs to the technical field of biology, and provides a reagent for detecting human leukocyte antigen B site 1502 genotype (HLA-B*1502), application of the reagent in preparation of akit for guiding administration of antiepileptic drugs such as carbamazepine, oxcarbazepine, phenytoin and lamotrigine, a corresponding kit and a detection method of the kit. According to the HLA-B*1502 genotyping, three groups of MIX reaction solutions are detected by adopting a PCR-fluorescent probe method, and target nucleic acid molecules are circularly amplified through an amplification reaction, so that a fluorescence generation group is indirectly combined with an amplified target nucleotide sequence; the amount of fluorescence generated by the fluorescence generation group is determined, and the existence of the target nucleotide is determined. The detection reagent comprises a nucleic acid amplification system of three groups of MIX reaction solutions, wherein the nucleic acid amplification system comprises an upstream primer 1 and a downstream primer 1 which can be combined with target nucleotide, and an upstream primer 2 and a downstream primer 2 which can be combined with the target nucleotide; and three groups of probes 1 and probes 4 of a fluorescence detection system matched with the nucleic acid amplification system.
