The invention discloses a vascular condition detection method and a vascular condition detection apparatus based on a heart point fluctuation conduction property. The method comprises the following steps: making a flexible detection terminal attached to the outer side of the skin of cardiac muscle or vascular wall, dispersing a cardiac muscle or vascular wall detection region into a plurality of preset detection points, and through the active transmitting of ultrasonic wave and the array receiving of ultrasonic echo, implementing multi-dimension detection on point fluctuations or point pulse waves by virtue of back-end inversion; and identifying a vascular conduction property by virtue of a digital signal processing method by taking the plurality of the point fluctuations of the cardiac muscle and the plurality of the point pulse waves in some vascular detection region as multi-input and multi-output signals, decomposing the property so as to obtain a vascular conduction property of some section, and implementing characteristic comparison after characteristic extraction so as to achieve vascular condition and disease prediction and diagnosis. The apparatus comprises a plurality of flexible detection terminals having ultrasonic wave transmitting and receiving capability, a control module and a computation module, wherein transmitting and receiving integrated ultrasonic probe arrays are arranged the flexible detection terminals and the arrays are fixedly arranged on flexible circuit boards.

The invention provides a contrast medium used for glioma targeted magnetic resonance and fluorescence dual modality imaging, and a preparation method thereof. The contrast medium is composed of an acrylamide monomer, an allyl monmer containing sulfhydryl or carboxyl or amidogen, superparamagnetic iron oxide nanoparticles, a fluorochrome and lactoferrin. The preparation method comprises following steps: the acrylamide monomer and the allyl monmer containing sulfhydryl or carboxyl or amidogen are subjected to polymerization reaction so as to obtain a copolymer nanogel; the superparamagnetic iron oxide nanoparticles are added in polymerization reaction process so as to obtain a superparamagnetic copolymer nanogel; the fluorochrome and lactoferrin and combined via covalent bonds so as to obtain fluorochrome labeled lactoferrin; and the superparamagnetic copolymer nanogel and fluorochrome labeled lactoferrin are combined via covalent bonds so as to obtain the contrast medium used for glioma targeted magnetic resonance and fluorescence dual modality imaging. The contrast medium possesses characteristics such as high specificity, selectivity and contrast effect, and low toxic and side effect; and is capable of realizing dual modality imaging.

The invention provides a lumbar intervertebral disc protrusion determination method and system. The determination method includes: acquiring surface electromyogram signals of a waist and a back; performing filtering treatment on the acquired surface electromyogram signals; performing feature value extraction on the filtered surface electromyogram signals; and performing comprehensive analysis on a waist muscle and a back muscle according to the acquired feature values so as to determine lumbar intervertebral disc protrusion. The lumbar intervertebral disc protrusion determination method and system are simple and practical, can perform preliminary determination on a lumbar intervertebral disc without the complex principle and complex devices; and the determination method can achieve therapeutic effect evaluation and recovery evaluation on the lumbar intervertebral disc protrusion, and the cost is low.
