Abrégé
A modified hemofiltration method for clearing peripheral α-synuclein aggregates in patients with neurodegenerative diseases is provided, which falls into the field of medicine. Specifically, a ratio S of synuclein dimers in blood is obtained; a blood flow velocity and an exchange membrane area for hemofiltration are determined through clinical trial data or historical literature data; hemofiltration is performed by the determined blood flow velocity and exchange membrane area, a calculation model of the ratio S of different synuclein dimers and an exchange membrane aperture D required for hemofiltration is constructed by linear regression; a clearance rate of synuclein dimers can be estimated by setting hemofiltration parameters with the calculation model. It is found that hemofiltration is beneficial to reducing the level of peripheral α-synuclein aggregates in patients with neurodegenerative diseases. Therefore, the calculation model is constructed, which provides scientific data and a new solution for clinically relieving α-synuclein-related toxicity symptoms.

Provided are a segmentation method and device based on an image of radionuclide imaging, including: determining a potential target region from an image of radionuclide imaging using a standardized value of pixels in the image of radionuclide imaging and an average standardized value and a standard deviation of pixels in a non-target region, and according to the boundary pixels and pixels within a boundary of the potential target region, and the average standardized value of the pixels of the non-target region, finally determining the boundary of a target of interest. The method or device needs to receive a non-target region selected by a user only when calculating an average standardized value and a standard deviation of pixels in the non-target region, thus significantly reducing manual intervention of a link, so as to avoid the subjectivity of segmentation results and improve the certainty of the segmentation results.
