A method, system, and an apparatus for stimulating a cranial nerve of a patient to treat a disorder, such as a metabolic or an endocrine disorder associated with the thyroid gland with an implantable medical device are provided. The method comprises coupling an electrode to the cranial nerve selected from the group consisting of a vagus nerve, a trigeminal nerve, and a glossopharyngeal nerve. The method further includes generating an electrical signal to treat a disorder associated with the thyroid gland. The electrical signal may be applied to the cranial nerve using the electrode to provide electrical nerve stimulation therapy to the patient. For treating a patient with a metabolic or an endocrine disorder associated with the thyroid gland, a neurostimulator may be adapted to apply an electrical stimulus to the vagus nerve and/or a branch of the vagus nerve associated with the thyroid gland. By balancing hormonal imbalance, the neurostimulator may provide electrical nerve stimulation therapy to the patient, thereby treating a target metabolic or an endocrine disorder associated with the thyroid gland.

The invention relates to auxiliary medical diagnoses, and aims to provide a method for automatically identifying whether a thyroid nodule is benign or malignant based on a deep convolutional neural network. The method for automatically identifying whether the thyroid nodule is benign or malignant based on the deep convolutional neural network comprises the following steps: reading B ultrasonic data of thyroid nodules; performing preprocessing for thyroid nodule images; selecting images, and obtaining nodule portions and non-nodule portions through segmentations; averagely dividing the extracted ROIs (regions of interest) into p groups, extracting characteristics of the ROIs by utilizing a CNN (convolutional neural network), and performing uniformization; taking p-1 groups of data as a training set, taking the remaining one group to make a test, and obtaining an identification model through training to make the test; and repeating cross validation for p times, and then obtaining an optimum parameter of the identification model. The method can obtain the thyroid nodules through the automatic segmentations by means of the deep convolutional neural network, and makes up for the deficiency that a weak boundary problem cannot be solved based on a movable contour and the like; and the method can automatically lean and extract valuable feature combinations, and prevent the complexity of an artificial feature selection.

In accordance with the present invention, it has been discovered that various members of the steroid/thyroid superfamily of receptors can interact with the insect-derived ultraspiracle receptor, to form multimeric species. Accordingly, the interaction of at least one member of the steroid/thyroid superfamily of receptors with at least the dimerization domain of the ultraspiracle receptor modulates the ability of said member of the steroid/thyroid superfamily of receptors to transactivate transcription of genes maintained under hormone expression control in the presence of the cognate ligand for said member of the superfamily.

In accordance with the present invention, it has been discovered that various members of the steroid/thyroid superfamily of receptors can interact to form multimeric species comprising a complex of more than one receptor. Accordingly, the interaction of a first receptor species with a second receptor species modulates the ability of the first receptor species to trans-activate transcription of genes maintained under hormone expression control in the presence of the cognate ligand for said first receptor.

The invention discloses a transfer learning and feature fusion-based ultrasonic thyroid nodule benign and malignant classification method. The method comprises the following steps of firstly preprocessing an ultrasonic image and zooming the ultrasonic image to a uniform size; extracting traditional low-level features of the ultrasonic image; extracting high-level semantic features of the ultrasonic image by using a model obtained in a natural image through deep neural network training through a transfer learning method; fusing the low-level features with the high-level features; carrying out feature screening by utilizing distinction degree of benign and malignant thyroid nodules so as to obtain a final feature vector which is used for training a support vector machine classifier; and carrying out final thyroid nodule benign and malignant classification. According to the method disclosed by the invention, the low-level features and the high-level features are fused, and salient feature screening is carried out, so that the problem that the ability of single features for describing thyroid nodule features on the level of semantic meaning is insufficient is solved, and the classification precision is effectively improved; and through importing the transfer learning, the problems that the medical sample images are few and the deep features can not be obtained by direct training are solved.
