Abstract: Some embodiments of the disclosure provide a decellularized heart valve (DHV) composite, a preparation method of the DHV composite, and a use of the DHV composite. In some examples, the preparation method of the DHV composite includes the following steps: S1, conducting a reaction I on a DHV with a copper chloride-dopamine hydrochloride mixed solution to obtain a copper ion-modified DHV; and S2, conducting a reaction II on the copper ion-modified DHV with a GDF11 solution to obtain the DHV composite. In other examples, the present disclosure provides a use of the DHV composite in preparation of a tissue-engineered heart valve (TEHV). In further examples, the TEHV is a heart valve (HV) with remodeling and regeneration capabilities.

Abstract: A medical communication system based on an Internet of Things is provided.

Abstract: Some embodiments of the disclosure provide a digital medical image teaching and research system. In some examples, the system includes a management side, a learning side, and a central processing unit. Both the management side and the learning side are connected to the central processing unit. In other examples, the management side includes an administrator login module, a management side control module, a teaching video module, a database, and a network connection module. The management side is configured to acquire medical image data and to generate a teaching video for scientific research personnel to perform scientific research and learning personnel to learn. The learning side includes a learning login module, a teaching video application module, and a learning side control module. The learning side is used for learning the teaching video. In further examples, a scientific research side is for the scientific research personnel to perform scientific research.

Abstract: Some embodiments of the disclosure provide a method for detecting an anti-chimeric antigen receptor (CAR) antibody against humanized CAR T cells. In some examples, the method include following steps. S1. Transfecting a humanized CAR into Chinese hamster ovary (CHO) cells into using lentivirus to generate CHO cells expressing CAR as target cells. S2. Collecting samples to be tested. S3. Preparing different concentrations of standards using human proteins corresponding to a target of the CAR and establishing a standard curve. S4. Incubating the target cells with the different concentrations of standards and the samples to be tested, and capturing the anti-CAR antibody. S5. Incubating a phycoerythrin (PE)-conjugated anti-human IgG Fc antibody with CHO cells for labeling. S6. Calculating the anti-CAR antibody by detecting average fluorescence intensities of the standards, blank control, and the samples to be tested using flow cytometry.

Abstract: Some embodiments of the disclosure provide non-contact health monitoring and physiotherapy equipment. In some examples, the equipment includes a bed, a monitoring module, a physiotherapy module, a displacement device, and a machine vision monitoring device. An execution part of the displacement device is connected to the bed and/or the monitoring module to enable at least one of the bed and the monitoring module to move relative to each other. The machine vision monitoring device is mounted on the bed or the monitoring module and connected to the displacement device in a communication manner. The machine vision monitoring device is configured to identify a limb position of the patient lying on the bed to provide coordinates for moving monitoring module to the displacement device. The displacement device is configured to drive the monitoring module to align with any part of the bed from any angle.
