The invention relates to a cutting knife which comprises a cutting assembly, a collecting assembly and an outer pipe assembly, the cutting assembly and the collecting assembly are contained in the outer pipe assembly in a compressible mode, and the cutting assembly and the collecting assembly can move relative to the outer pipe assembly and are released outside the outer pipe assembly. The collecting assembly is released on one side of the vein valve, the cutting assembly is released on one side of the vein valve, and the cutting assembly can move towards the collecting assembly so as to cut the vein valve and store cut valve fragments in the cutting assembly and the collecting assembly. After the cutting knife cuts a vein valve, cut valve fragments are stored in the cutting assembly and the collecting assembly and withdrawn from the human body along with the outer tube assembly, and then the cut valve fragments are prevented from flowing along with blood to escape into the artery. Serious consequences such as sudden cardiac arrest and cerebral anoxia caused by the fact that valve fragments enter the artery are avoided.

The invention relates to the technical field of medicine, in particular to a pharmaceutical composition for preventing and / or treating hypoxic injury and application, the pharmaceutical composition is prepared by compounding ginseng stem and leaf total saponins, ginkgo leaf extract and ligustrazine according to the mass ratio of (45-55): (45-55): (0.8-1.5); the hypoxia injury comprises cerebral hypoxia injury and myocardial hypoxia injury. The pharmaceutical composition provided by the invention has the functions of preventing and / or treating myocardial injury, brain tissue and motor hypofunction caused by hypoxia.

A method and composition for enhancing synthesis of adenosine triphosphate (ATP) in mitochondria of brain cells of a human includes providing the composition including a synergistic compound of choline cation and succinate anion (2-) in a molar ratio of choline:succinate of 2:1 in the form of dicholine succinate (DiSu) in a daily dosage that synergistically increases ATP levels in brain cells. The method and composition are formulated to affect frequency and / or severity of various conditions by regulating ATP levels in brain cells. The method and composition are formulated to reduce rate of decline in the brain under conditions of cerebral hypoxia, e.g., due to aging, injury, illness, and the similar conditions.

The application discloses a kind of functionalization exosome-traditional Chinese medicine small molecule composite preparation T-pEXOs@GB and its preparation method and application.The composite preparation encapsulates ginkgolide B (GB) in the exosome of healthy plasma, and is functionally modified neuron target peptide RVG (DSPE-PEG-RVG) on its surface, so that it has brain targeting and oxygen supply functions.The preparation method provided by the application can efficiently and controllably prepare the composite preparation with uniform particle size and good stability.The T-pEXOs@GB composite preparation of the application can be targeted to deliver to brain ischemia and hypoxia injury area, significantly reduce oxidative stress and inflammatory response, reduce cerebral infarction volume, improve neurological deficit score, and improve the survival rate of animal model, and can be used to prepare drugs for preventing and treating acute high altitude cerebral hypoxia, ischemic stroke, neonatal hypoxic-ischemic encephalopathy and other cerebral ischemia and hypoxia injury, and has good market prospect.

The invention relates to the technical field of biological medicines and functional foods, and particularly discloses a giant salamander peptide composition for resisting cerebral hypoxia injury as well as a preparation method and application of the giant salamander peptide composition. The active ingredients of the giant salamander peptide composition are prepared by compounding giant salamander peptide, marine fish oligopeptide and chitosan according to a specific weight part ratio. The composition is prepared through a simple physical mixing method, all the components have a synergistic effect, and brain hypoxia injury is comprehensively resisted through a multi-channel and multi-target mechanism. Experimental results show that the ternary composition can remarkably improve dyskinesia caused by hypoxia, relieve apoptosis, inhibit inflammatory response, relieve oxidative stress and repair the integrity of a blood-brain barrier, and the effect of the ternary composition is far better than that of independent use of giant salamander peptide. The composition is high in safety and simple and convenient in process, and can be used for developing medicines or functional foods for prevention and adjuvant treatment of cerebral hypoxia injury.

The invention discloses a multi-modal monitoring-based SAH patient cerebral hypoxia and ischemia real-time evaluation method, and belongs to the technical field of medical and industrial integration. The method comprises the following steps: collecting end-expiratory carbon dioxide data and electroencephalogram data; preprocessing the electroencephalogram data; calculating the power of each frequency band; calculating a delta wave power proportion according to each frequency power; dPR differences of different brain regions of the brain before and after treatment and in the treatment period and the interval period are evaluated through statistical analysis. According to the method, the electroencephalogram is combined with the end-tidal carbon dioxide data, the change of low-frequency activity of the brain is quantified by calculating the ratio of the electroencephalogram delta wave power, and the cerebral cortex hypoxia and ischemia degree of the SAH patient during respiratory therapy is evaluated according to the change value.
