The invention discloses application of a PLAU signal channel inhibitor in treating ischemic cerebral apoplexy and a pharmaceutical composition, and belongs to the field of biological medicine. The PLAU signal channel inhibitor inhibits the activation of an NF-kappa B channel and reduces the generation of inflammatory factors (IL-1beta, IL-6 and TNF-alpha) by inhibiting the expression of PLAU protein in cells. Experiments prove that the PLAU signal channel inhibitor can remarkably improve related pathological indexes of ischemic cerebral apoplexy, the cerebral infarction area is reduced by more than or equal to 30%, the vascular endothelial cell activity is improved by more than or equal to 25%, the inflammatory factor level is reduced by more than or equal to 40%, and the protective effect on cerebral ischemia reperfusion injury is superior to the overall effect of a traditional Chinese medicine compound. The invention provides a clear mechanism basis for targeted therapy of ischemic cerebral apoplexy.

The application provides a cerebral apoplexy postoperative sign monitoring system, which is fused with a nerve motor function evaluation wristband and a head-mounted brain electrical impedance dynamic imaging device, and breaks through the blind area of postoperative monitoring. The wristband device collects upper limb electromyographic signals and joint motion mechanics parameters through a microneedle electrode array and a distributed piezoresistive sensor, drives a neural network to output a standardized motor score based on time-frequency domain features containing electromyography, joint angle, trajectory smoothness and grip force change rate, and is related to a clinical Fugl-Meyer scale; the imaging device adopts a multi-ring electrode array and an improved D-bar algorithm to reconstruct a brain electrical conductivity distribution map, constructs a multi-level decision tree early warning model by extracting impedance change rate Delta Z, spatial gradient entropy SGE and hemisphere asymmetry Asym, and realizes brain edema detection. Through multi-modal data fusion and minute-level response, the system solves the fragmentation problem of postoperative monitoring and provides precise decision support for cerebral apoplexy rehabilitation.

The invention belongs to the technical field of medical nursing instruments. The invention discloses a cerebral apoplexy paralyzed patient transfer instrument. The cerebral apoplexy paralyzed patient transfer instrument comprises a base with walking wheels, wherein a pushing frame is arranged at the top of one side of the base; longitudinal sleeves are movably arranged on the two sides of the pushing frame in a sleeving mode, and each longitudinal sleeve is connected with a synchronous regulator arranged on the base. The longitudinal sleeve is further provided with a sitting and leaning structure which is used for supporting a patient to sit and lean so that off-bed transfer operation can be conveniently carried out. The monitoring structure is used for monitoring the sitting and leaning state of the patient and the connecting stability of the guardrail components of the sitting and leaning structure. The device has the advantages that accidental injuries to the cerebral apoplexy paralyzed patient in the position transferring process can be reduced, and the body burden and labor intensity of medical staff are relieved.
