Description

Technical Field

[0001] The present invention relates to the technical field of lipoprotein subtype component classification, and in particular to a lipoprotein subtype component classification method, device, equipment and storage medium. Background Art

[0002] Low-density lipoprotein (LDL) is the primary carrier of cholesterol in the body and can be divided into seven types. However, excessive LDL levels can trigger an inflammatory response. Oxidized LDL, after being engulfed by macrophages, can form fatty plaques in blood vessels, leading to dyslipidemia or arteriosclerosis. Smaller LDLs are more susceptible to oxidation, forming plaques on blood vessel walls. LDL types 1 and 2 (large LDL) are considered "normal LDL" and are responsible for normal cholesterol transport. LDL types 3 to 7 (small LDL) are considered "bad or abnormal LDL" and are easily oxidized, contributing to cardiovascular disease. The relationship between "small" LDL levels and coronary artery disease has been established. Measuring total LDL alone does not indicate cardiovascular disease risk because it cannot distinguish between "large" and "small" LDL. Even if total LDL levels are normal, an elevated level of small, dense (3-7) LDL can more than triple the risk of cardiovascular disease. Discovering the risk of disease at an early stage can significantly prevent and treat the occurrence of cardiovascular disease.

[0046] Example 1

[0047] Figure 1 This is a flow chart of a lipoprotein subtype component classification method provided by the first embodiment of the present invention. This embodiment is applicable to the classification of low-density lipoprotein subtype components. The method can be executed by a lipoprotein subtype component classification device. The lipoprotein subtype component classification device can be implemented in the form of hardware and / or software.

[0049] S120 , dividing the reagent scan image into low-density lipoprotein subtype components based on predetermined target segmentation points, wherein the target segmentation points are obtained by processing sample scan images of multiple sample lipoprotein reagents.

[0050] In the embodiments of the present invention, image processing is performed in advance based on a lipoprotein reagent having distinct characteristics to determine target segmentation points, i.e., division points, for LDL subclassification. When performing lipoprotein subclassification, the predetermined target segmentation points are ultimately applied to the reagent scan image to achieve automated segmentation.

[0053] Example 2

[0054] Figure 2 is a flow chart of a method for dividing lipoprotein subtype components provided by Example 2 of the present invention. Based on the above embodiment, this embodiment optimizes the determination of the target segmentation point, such as Figure 2a As shown, the method includes:

[0055] S210 , obtaining sample scan images of a plurality of sample lipoprotein reagents, and processing the sample scan images to obtain a single sample image.

[0056] In this embodiment, a small batch of lipoprotein reagents with obvious characteristics are used as sample lipoprotein reagents, and reagent scanning images of the sample lipoprotein reagents after electrophoresis are obtained as sample scanning images.

[0057] In one implementation, processing the original scanned image to obtain a single sample image includes: segmenting the original scanned image by extracting a valid region to obtain a plurality of the single sample images. Optionally, separating the reagents in the sample scanned image and extracting the valid regions thereof, and then obtaining an image of the single reagent image as the single sample image.

Figure 2b The left part of the middle arrow is a schematic diagram of the sample scan image. Figure 2b The part to the right of the middle arrow is a schematic diagram of a single scan image.

[0059] S220 : Determine a target segmentation point corresponding to the single sample image according to the grayscale value waveform image of the single sample image.

[0060] In this embodiment, by performing gray value analysis on a captured single sample image, a gray value waveform image can be drawn, and target segmentation points can be determined from the gray value waveform image according to certain mathematical rules.

[0061] In general, mathematical rules are used to find the segmentation points of each component of low-density lipoprotein (LDL) on the grayscale waveform image, and the peaks of very low-density lipoprotein (VLDL) and high-density lipoprotein (HDL) are used as the starting and ending points to calculate the percentage. Then, the data of each segmentation point of the batch are statistically analyzed, and its confidence interval is calculated. The target segmentation point is determined based on the confidence interval.

[0062] In one embodiment of the present invention, determining the target segmentation point corresponding to the single sample image based on the grayscale value waveform image of the single sample image includes: determining a single demarcation point corresponding to the single sample image based on the grayscale value waveform image of the single sample image; and determining the target segmentation point based on each of the single demarcation points. After generating the grayscale value waveform image, finding a single image segmentation line according to a certain mathematical rule, determining a single demarcation point based on the single image segmentation line, and then determining the target segmentation point based on the single demarcation point.

[0063] Figure 2c This is a schematic diagram of segmenting a grayscale waveform image provided by the second embodiment of the present invention. Figure 2c As shown in the figure, the vertical axis is the statistical gray value, and the horizontal axis represents the position, corresponding to a single sample image. Figure 2c The two highest peaks are the peak of high-density lipoprotein HDL and the peak of very low-density lipoprotein VLDL, respectively. The remaining dotted dividing lines are the dividing lines found by mathematical rules. The dividing points corresponding to the remaining dotted dividing lines are the single dividing points corresponding to a single sample image.

[0064] In one implementation, determining the single demarcation point corresponding to the single sample image based on the grayscale value waveform image of the single sample image includes: performing waveform segmentation on the grayscale value waveform image and using the connection point of adjacent waveforms as the single demarcation point. Multiple waveforms contained in the grayscale value waveform image can be identified, and the connection point of adjacent waveforms can be used as the single demarcation point.

[0065] In one embodiment of the present invention, the target segmentation point is determined based on each of the single demarcation points, including: statistical verification of each of the single demarcation points to determine the confidence interval of each of the single demarcation points; determining the component segmentation ratio of the single demarcation point based on the confidence interval of each of the single demarcation points; and determining the target segmentation point corresponding to the single demarcation point according to the component segmentation ratio. The coordinates of multiple single demarcation points of a single sample image can be searched in batches, and the percentage of the total length of each image in the batch is obtained based on the coordinates of each single demarcation point, where the total length refers to the distance between the two highest peaks in the grayscale value waveform image. The statistical percentage points are then statistically verified, and all points conform to the normal distribution after boxcox transformation, and the confidence interval of each single demarcation point is calculated on this basis. The component segmentation ratio corresponding to the single demarcation point is then determined based on the confidence interval, and finally the target segmentation point corresponding to the single demarcation point is determined based on the component segmentation ratio. The target segmentation point corresponding to each single demarcation point is determined in sequence by the above method until the target segmentation points corresponding to all single demarcation points in all single sample images are obtained.

[0066] Determining the component split ratio corresponding to a single demarcation point based on a confidence interval may include determining an eigenvalue of the confidence interval based on the upper and lower limits of the confidence interval, and using the eigenvalue of the confidence interval as the component split ratio corresponding to the single demarcation point. The eigenvalue of the confidence interval may be a weighted sum of the upper and lower limits.

Figure 2e This is a schematic diagram of a confidence interval of a single dividing point provided in Example 2 of the present invention. Figure 2d and Figure 2e The confidence intervals of two individual cut-off points are schematically shown in FIG.

[0068] In one implementation, the component splitting ratio of each single demarcation point is determined based on the confidence interval of each single demarcation point, including: taking the middle value of the confidence interval as the component splitting ratio of the single demarcation point. Optionally, the middle value of the confidence interval, that is, the average value of the upper limit and the lower limit of the confidence interval, is taken as the component splitting ratio of the single demarcation point. Figure 2d As shown, 36.5% can be taken as Figure 2d The component division ratio corresponding to a single dividing point in Figure 2e As shown, 47.3% can be taken as Figure 2e The component division ratio corresponding to a single dividing point in .

[0069] In one embodiment of the present invention, the target segmentation point corresponding to the single demarcation point is determined according to the component segmentation ratio, including: determining the total length of the distance from the peak of very low density lipoprotein as the starting point to the peak of high density lipoprotein as the end point in the single sample image; obtaining the target segmentation point based on the component segmentation ratio and the total length of the distance. Optionally, the peak of VLDL in each waveform is used as the starting point, the peak of HDL is used as the end point, and the distance between the two points is set as the total length. The distance of the corresponding segmentation point relative to the remaining starting point can be obtained by multiplying the two percentage points in the above example by the total length, and the coordinates of the starting point are added to obtain the coordinates of the segmentation point, that is, the coordinates of the target segmentation point. The target segmentation points corresponding to the remaining single demarcation points can be calculated using the same method as above.

[0070] S230: Obtain a reagent scanning image of the reagent to be used for lipoprotein separation.

[0071] S240 , dividing the reagent scan image into low-density lipoprotein subtype components based on predetermined target segmentation points.

[0072] The technical solution of this embodiment is to obtain sample scan images of multiple sample lipoprotein reagents, process the sample scan images to obtain a single sample image; determine the target segmentation points corresponding to the single sample image based on the grayscale value waveform image of the single sample image; and use a portion of lipoprotein reagents with more obvious features as sample lipoprotein reagents to perform statistical analysis on the reagent images to ultimately determine the target segmentation points, so that accurate and automated batch segmentation of lipoprotein subtype components can be achieved based on the determined target segmentation points applied to the reagent scan images of the lipoprotein reagents to be divided.
