[0002] Currently, for rare diseases, clinicians receive a relatively small number of related patients, and the accumulation of experience is limited. For clinicians with insufficient experience, it is very difficult to accurately predict the condition of patients, and it is impossible to take treatment measures for patients in advance. Many patients miss the best treatment time, increasing the treatment time and cycle.

[0003] Therefore, how to predict the development trend of rare diseases has become an urgent problem to be solved in this field. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a method, apparatus, electronic device, and medium for predicting the development trend of rare diseases, which can accurately predict the development trend of rare diseases.

[0005] In a first aspect, an embodiment of this application provides a method for predicting the development trend of rare diseases, and the method includes: Obtain the type of rare disease corresponding to the target rare disease patient and the physical examination data within the current time period; For each time point within the current time period, determine whether there is a missing physical examination item corresponding to this time point according to the physical examination data at this time point and the set of physical examination items corresponding to the type of rare disease; a missing physical examination item refers to a physical examination item without physical examination data; If there is a missing physical examination item corresponding to this time point, then based on the physical examination item association relationship corresponding to the type of rare disease and the physical examination data at this time point, determine the supplementary weight corresponding to each missing physical examination item at this time point; the physical examination item association relationship includes other physical examination items associated with each physical examination item; Determine the missing physical examination item with the largest supplementary weight as the target missing physical examination item at the time point; Among the physical examination data at this time point, input the physical examination data corresponding to other physical examination items associated with the target missing physical examination item at this time point into the supplementary model corresponding to the type of rare disease and the target missing physical examination item, and obtain the physical examination data corresponding to the target missing physical examination item at this time point; and jump to determine whether there is a missing physical examination item corresponding to this time point according to the physical examination data at this time point and the set of physical examination items corresponding to the type of rare disease to continue execution; Divide all the physical examination data according to the data characteristics of all the physical examination data within the current time period to obtain the physical examination data within multiple target time periods; Input the physical examination data within each target time period into the disease index determination model corresponding to the rare disease type to obtain the disease index corresponding to each target time period; the disease index determination model is trained based on the physical examination data samples and the corresponding disease index labels. Generate a target trend line graph with the target time period as the abscissa and the corresponding disease index as the ordinate. Calculate the similarity between the target trend line graph and each control trend line graph; the control trend line graph is generated based on the disease indices corresponding to the patients of the rare disease type over multiple time periods. Determine the disease development trend of the rare disease patient for the rare disease type according to the similarity.

[0006] In a possible implementation manner, the physical examination item association relationship corresponding to the rare disease type is determined through the following steps: Obtain the historical physical examination data corresponding to each physical examination item in the physical examination item set for multiple patients corresponding to the rare disease type at each historical moment. Calculate the initial correlation coefficient between each pair of physical examination items corresponding to each patient based on all the historical physical examination data corresponding to the patient. For each pair of physical examination items, calculate the average value of the initial correlation coefficients between the two physical examination items corresponding to all patients to obtain the target correlation coefficient between the two physical examination items. If the target correlation coefficient between two physical examination items is greater than or equal to the preset correlation coefficient, there is an association relationship between the two physical examination items.

[0007] In a possible implementation manner, calculating the initial correlation coefficient between each pair of physical examination items corresponding to each patient based on all the historical physical examination data corresponding to the patient includes: Substitute the historical physical examination data of each pair of physical examination items corresponding to the patient into the following formula to calculate the initial correlation coefficient between each pair of physical examination items corresponding to the patient: ; where is the initial correlation coefficient between the historical physical examination data of the first physical examination item X and the historical physical examination data of the second physical examination item Y among the two physical examination items corresponding to the patient, is the distance covariance between the historical physical examination data of the first physical examination item X and the historical physical examination data of the second physical examination item Y corresponding to the patient, is the distance variance of the historical physical examination data of the first physical examination item X corresponding to the patient, is the distance variance of the historical physical examination data of the second physical examination item Y corresponding to the patient.

[0010] In a possible implementation, the disease development trend of the rare disease patient for this rare disease type is determined according to the similarity, including: If the maximum value of the similarity is greater than or equal to the preset similarity, then the actual disease development trend corresponding to the control trend line with the largest similarity is determined as the disease development trend corresponding to this standard rare disease patient; If the maximum value of the similarity is less than the preset similarity and there is a target point with a tangent slope of 0 in the target trend line, then calculate the difference between the disease index corresponding to the target point with the latest calculation time and the disease index of the point with the latest time in the target trend line; If the difference is greater than 0, the disease development trend corresponding to the rare disease patient is a trend of improvement; If the difference is less than 0, the disease development trend corresponding to the rare disease patient is a trend of deterioration.

[0021] It should be noted that the term "including" will be used in the embodiments of the present application to indicate the existence of the features stated thereafter, but does not exclude adding other features.

[0022] The following provides a detailed description of a method for predicting the disease development trend of a rare disease provided by the embodiments of the present application.

[0023] Refer toFigure 1 As shown in Figure 1 , it is a schematic flowchart of a method for target rare disease patients provided by an embodiment of the present application. The following describes each step of the embodiment of the present application by way of example: S101. Obtain the rare disease type corresponding to the target rare disease patient and the physical examination data within the current time period.

[0024] In the embodiment of the present application, the target rare disease patient refers to a patient whose disease development trend of the rare disease needs to be predicted. The rare disease type corresponding to the target rare disease patient refers to the rare disease type suffered by the target rare disease patient (such as hemophilia, myasthenia gravis, neuromyelitis optica, etc.). The duration corresponding to the current time period can be one week, half a month, etc., which can be determined according to the actual situation. The physical examination data can be uploaded to the physical examination database of the medical decision-making assistance system by the target rare disease patient when the doctor conducts a follow-up visit, or can be uploaded to the physical examination database of the medical decision-making assistance system by the doctor when conducting a follow-up visit on the target rare disease patient. Different rare disease types correspond to different sets of physical examination items. The physical examination data within the current time period should be the physical examination values of the physical examination items (such as blood pressure, blood sugar, etc.) in the set of physical examination items corresponding to the rare disease type.

[0025] Among them, the medical decision-making assistance system is a software development system that can be used to execute the method for predicting the disease development trend of rare diseases provided by the embodiment of the present application. In the medical decision-making assistance system, multiple data sets from different sources are stored (the data can include medical information, papers, rare disease treatment data of patients, etc.), with multiple data types (text data, tabular data, images, videos, etc.), multiple data sources (medical devices, user input, etc.), multiple data owners (patients, rare disease medical experts, etc.), multiple time points, multiple regions, etc. Therefore, this system is a medical decision-making assistance system based on multi-source data.

[0026] S102. For each time point within the current time period, determine whether there is a missing physical examination item according to the physical examination data at this time point and the set of physical examination items corresponding to the rare disease type; a missing physical examination item refers to a physical examination item without physical examination data.

[0027] In the embodiment of the present application, a physical examination item without corresponding physical examination data in the set of physical examination items corresponding to the rare disease type is a missing physical examination item. For example, the set of physical examination items corresponding to the rare disease type includes physical examination item 1, physical examination item 2, and physical examination item 3. The physical examination data corresponding to this time point includes the physical examination data of physical examination item 1 and the physical examination data of physical examination item 2. Therefore, the missing physical examination item corresponding to the physical examination data at this time point is physical examination item 3.

[0028] S103. If there are missing physical examination items corresponding to this time point, based on the physical examination item association relationship corresponding to this rare disease type and the physical examination data at this time point, determine the supplementary weights corresponding to each missing physical examination item at this time point.

[0029] In the embodiment of the present application, different rare disease types correspond to different physical examination item association relationships. The physical examination item association relationship includes other physical examination items associated with each physical examination item, and the number of other physical examination items associated with each physical examination item can be one or more. Specifically, for each missing physical examination item, according to the physical examination data at this time point, count the number of other physical examination items associated with this missing physical examination item and corresponding to the physical examination data, and obtain the supplementary weight corresponding to this missing physical examination item; among them, the physical examination data of other physical examination items can be obtained from the physical examination database in step S101, or can be supplemented through the supplementary model; the larger the value corresponding to the supplementary weight, the more accurate the physical examination data supplemented through the supplementary model.

[0030] In addition, the physical examination item association relationship corresponding to this rare disease type is determined through the following steps: Step 1. Obtain the historical physical examination data corresponding to each physical examination item in the physical examination item set for multiple patients corresponding to this rare disease type at each historical moment.

[0031] Example: The physical examination item set corresponding to this rare disease type includes physical examination item 1, physical examination item 2, and physical examination item 3; obtain the physical examination data of multiple patients suffering from this rare disease type at multiple historical moments in the physical examination database; the physical examination data of each patient at each historical moment includes the physical examination value corresponding to physical examination item 1 for this patient at this historical moment, the physical examination value corresponding to physical examination item 2 for this patient at this historical moment, and the physical examination value corresponding to physical examination item 3 for this patient at this historical moment.

[0032] Step 2. Calculate the initial correlation coefficient between every two physical examination items corresponding to each patient according to all the historical physical examination data corresponding to each patient.

[0033] In the embodiment of the present application, for each patient, it is necessary to calculate the initial correlation coefficient between every two physical examination items corresponding to this patient according to the historical physical examination data of this patient; the larger the initial correlation coefficient, the stronger the correlation between the two physical examination items corresponding to this patient.

[0034] Example, there are patient A and patient B; the physical examination item set includes physical examination item 1, physical examination item 2, and physical examination item 3; then for patient A, according to the historical physical examination data of patient A, calculate the initial correlation coefficient between physical examination item 1 and physical examination item 2 corresponding to patient A; according to the historical physical examination data of patient A, calculate the initial correlation coefficient between physical examination item 2 and physical examination item 3 corresponding to patient A; according to the historical physical examination data of patient A, calculate the initial correlation coefficient between physical examination item 1 and physical examination item 3 corresponding to patient A. For patient B, according to the historical physical examination data of patient B, calculate the initial correlation coefficient between physical examination item 1 and physical examination item 2 corresponding to patient B; according to the historical physical examination data of patient B, calculate the initial correlation coefficient between physical examination item 2 and physical examination item 3 corresponding to patient B; according to the historical physical examination data of patient B, calculate the initial correlation coefficient between physical examination item 1 and physical examination item 3 corresponding to patient B.

[0035] Specifically, substitute the historical physical examination data of every two physical examination items corresponding to the patient into the following formula to calculate the initial correlation coefficient between every two physical examination items corresponding to the patient: ; ; ; ; ; ; ; ; ; ; Among them, is the initial correlation term coefficient between the historical physical examination data of the first physical examination item X and the historical physical examination data of the second physical examination item Y among these two physical examination items corresponding to the patient, is the distance covariance between the historical physical examination data of the first physical examination item X and the historical physical examination data of the second physical examination item Y corresponding to the patient, is the distance variance of the historical physical examination data of the first physical examination item X corresponding to the patient, is the distance variance of the historical physical examination data of the second physical examination item Y corresponding to the patient; is the value corresponding to the i-th row and j-th column in the double-centered distance matrix of the historical physical examination data of the first physical examination item X corresponding to the patient; is the value corresponding to the i-th row and j-th column in the double-centered distance matrix of the historical physical examination data of the second physical examination item Y corresponding to the patient; is the value corresponding to the i-th row and j-th column in the distance matrix of the historical physical examination data of the first physical examination item X corresponding to the patient, The value corresponding to the i-th row and j-th column in the distance matrix of the historical physical examination data of the second physical examination item Y corresponding to this patient; The average value of the values corresponding to the i-th row in the distance matrix of the historical physical examination data of the first physical examination item X corresponding to this patient, The average value of the values corresponding to the i-th row in the distance matrix of the historical physical examination data of the second physical examination item Y corresponding to this patient, The average value of the values corresponding to the j-th column in the distance matrix of the historical physical examination data of the first physical examination item X corresponding to this patient, The average value of the values corresponding to the j-th column in the distance matrix of the historical physical examination data of the second physical examination item Y corresponding to this patient, The i-th historical physical examination data of the first physical examination item X corresponding to this patient, The j-th historical physical examination data of the first physical examination item X corresponding to this patient, The i-th historical physical examination data of the second physical examination item Y corresponding to this patient, The j-th historical physical examination data of the second physical examination item Y corresponding to this patient, where n is the number of elements in the distance matrix of the historical physical examination data of the first physical examination item X or the number of elements in the distance matrix of the historical physical examination data of the second physical examination item Y.

[0036] Step 3. For every two physical examination items, calculate the average value of the initial correlation coefficients between the two physical examination items corresponding to all patients to obtain the target correlation coefficient between the two physical examination items.

[0037] Example: There are patient A and patient B. For physical examination item 1 and physical examination item 2, add the initial correlation coefficient between physical examination item 1 and physical examination item 2 corresponding to patient A and the initial correlation coefficient between physical examination item 1 and physical examination item 2 corresponding to patient B to obtain a sum value, and divide this sum value by 2 to obtain the target correlation coefficient between physical examination item 1 and physical examination item 2.

[0038] Step 4. If the target correlation coefficient between the two physical examination items is greater than or equal to the preset correlation coefficient, there is an association relationship between the two physical examination items.

[0039] Step 5. If the target correlation coefficient between the two physical examination items is less than the preset correlation coefficient, there is no association relationship between the two physical examination items.

[0040] S104. Determine the missing physical examination item with the largest supplementary weight as the target missing physical examination item at this time point.

[0041] S105. Among the physical examination data at this time point, input the physical examination data corresponding to other physical examination items associated with the target missing physical examination item at this time point into the supplementary model corresponding to this rare disease type and this target missing physical examination item to obtain the physical examination data corresponding to the target missing physical examination item at this time point; and jump to determine whether there is a missing physical examination item corresponding to this time point based on the physical examination data at this time point and the set of physical examination items corresponding to this rare disease type to continue execution.

[0042] In the embodiment of the present application, different rare disease types and target missing physical examination items correspond to different supplementary models, and the supplementary model is used to supplement the physical examination data corresponding to the target missing physical examination item. The supplementary model is a deep learning model pre-trained with the physical examination data samples corresponding to other physical examination items associated with the missing physical examination item and the corresponding physical examination data labels at the same time of the same patient. The input is the physical examination data corresponding to other physical examination items associated with the missing physical examination item, and the output is the physical examination data corresponding to the missing physical examination item.

[0043] Here, to avoid inaccurate prediction of the subsequent disease development trend due to the possible incompleteness of the physical examination data stored in the physical examination database, the present application continues to supplement the physical examination data to be complete. In addition, after the present application supplements the physical examination data corresponding to each missing physical examination item, it re-determines the supplementary weight of other missing physical examination items to continue supplementing the missing physical examination item with the largest supplementary weight, improving the accuracy of the supplemented physical examination data.

[0044] S106. Divide all the physical examination data according to the data characteristics of all the physical examination data within the current time period to obtain the physical examination data within multiple target time periods.

[0045] In the embodiment of the present application, all the physical examination data within the current time period includes those obtained from the physical examination database in step S101 and supplemented by the supplementary model. The numerical dispersion degree of the physical examination data within the target time period should meet the preset dispersion degree condition, and the specific preset dispersion degree condition can be determined according to the actual situation, such as being set based on methods such as average, variance or average difference, so that the disease index corresponding to the subsequent determined target time period can represent the overall condition of this target time period.

[0046] Specifically, referring to Figure 2 As shown, it is a schematic flow chart of dividing physical examination data provided by the embodiment of the present application. The following will explain each step of the embodiment of the present application exemplarily: S201. Divide all the physical examination data according to the preset division duration to obtain the physical examination data within multiple initial time periods.

[0047] In the embodiments of the present application, the preset duration can be determined according to the actual situation, such as one day, two days, etc. By dividing according to the preset duration, the numerical dispersion degree of the physical examination data in each time period can be effectively reduced.

[0048] For example, if the physical examination data in the current time period is the physical examination data within one week, then dividing according to the preset duration of one day, the physical examination data from the 0th day to the 1st day, the physical examination data from the 1st day to the 2nd day, the physical examination data from the 2nd day to the 3rd day, the physical examination data from the 3rd day to the 4th day, the physical examination data from the 4th day to the 5th day, the physical examination data from the 5th day to the 6th day, and the physical examination data from the 6th day to the 7th day can be obtained.

[0049] S202. For each initial time period, if the variance of the physical examination data corresponding to any physical examination item in the initial time period is greater than the preset variance, then divide the physical examination data in the initial time period according to the physical examination data corresponding to the physical examination item with the largest variance in the initial time period to obtain the physical examination data in the target time period.

[0050] Specifically, divide the physical examination data in the initial time period according to the physical examination data corresponding to the physical examination item with the largest variance in the initial time period through the following steps: a. If the time point where the maximum value in the physical examination data corresponding to the physical examination item with the largest variance is located is not the latest time point in the initial time period and is not the earliest time point in the initial time period, then determine the time point where the maximum value is located as the splitting time point.

[0051] For example, the physical examination item with the largest variance in the initial time period is physical examination item 2. The physical examination data in the initial time period includes the physical examination data at 3:00, 4:00, 7:00, 8:00, 9:00, and 12:00. The maximum value in the physical examination data corresponding to physical examination item 2 is the physical examination data at 4:00, and 4:00 is not the latest time 12:00 corresponding to the physical examination data in the initial time period nor the earliest time 3:00 corresponding to the physical examination data in the initial time period. Then determine the time point where the maximum value is located as the splitting time point.

[0052] b. If the time point where the minimum value in the physical examination data corresponding to the physical examination item with the largest variance is located is not the latest time point in the initial time period and is not the earliest time point in the initial time period, then determine the time point where the minimum value is located as the splitting time point.

[0053] Example: The medical examination item with the largest variance in the initial time period is medical examination item 2. The medical examination data in the initial time period includes the medical examination data at 3:00, 4:00, 7:00, 8:00, 9:00, and 12:00. The minimum value in the medical examination data corresponding to medical examination item 2 is the medical examination data at 8:00. Since 8:00 is neither the latest time 12:00 nor the earliest time 3:00 corresponding to the medical examination data in the initial time period, the time point where the minimum value is located is determined as the splitting time point.

[0054] c. Divide the medical examination data in the initial time period at the splitting time point to obtain the medical examination data in the target time period.

[0055] Example: The medical examination data in the initial time period includes the medical examination data at 3:00, 4:00, 7:00, 8:00, 9:00, and 12:00. The splitting time points are 4:00 and 8:00. Then the obtained target time periods include 3:00 to 4:00, 4:00 to 8:00, and 8:00 to 12:00.

[0056] d. If the time point where the maximum value in the medical examination data corresponding to the medical examination item with the largest variance is located is the latest time point or the earliest time point in the initial time period, and the time point where the minimum value in the medical examination data corresponding to the medical examination item with the largest variance is located is the latest time point or the earliest time point in the initial time period, then the medical examination data in the initial time period is evenly split to obtain the medical examination data in two target time periods.

[0057] Example: The medical examination item with the largest variance in the initial time period is medical examination item 2. The medical examination data in the initial time period includes the medical examination data at 3:00, 4:00, 7:00, 8:00, 9:00, and 12:00. The maximum value in the medical examination data corresponding to medical examination item 2 is the medical examination data at 3:00, and the minimum value in the medical examination data corresponding to medical examination item 2 is the medical examination data at 12:00. Then the target time periods are 3:00 to 7:00 and 8:00 to 12:00.

[0058] S203. If the variance of the medical examination data corresponding to all medical examination items in the initial time period is less than or equal to the preset variance, then the medical examination data in the initial time period is determined as the medical examination data in the target time period.

Input the physical examination data within each target time period into the disease index determination model corresponding to the rare disease type to obtain the disease index corresponding to each target time period.

[0060] In the embodiment of the present application, each rare disease type corresponds to a disease index determination model. The disease index determination model is a deep learning model pre-trained through the physical examination data samples of the patients corresponding to the rare disease type within the target time period samples and the corresponding disease index labels. The input is the physical examination data sample, and the output is the disease index. The higher the disease index, the deeper the degree of the patient's illness.

[0061] S108. Generate a target trend line graph with the target time period as the abscissa and the corresponding disease index as the ordinate.

[0062] S109. Calculate the similarity between the target trend line graph and each control trend line graph. The control trend line graph is generated based on the disease indexes corresponding to the patients of the rare disease type in multiple time periods.

[0063] In the embodiment of the present application, each control trend line graph corresponds to an actual disease development trend. The disease development trend includes a trend of improvement, a trend of deterioration, and a trend of stability.

The actual disease development trend corresponding to the control trend line graph is determined manually based on the actual disease index development of the patients within the preset time period after each time period.

[0064] The similarity between the target trend line graph and each control trend line graph is calculated through the following steps: Step 1. If the length of the target trend line graph is greater than that of the control trend line graph, cut off the front part of the curve of the target trend line graph so that the remaining target trend line graph has the same length as the control trend line graph.

[0065] Step 2. If the length of the target trend line graph is less than that of the control trend line graph, cut off the front part of the curve of the control trend line graph so that the remaining target trend line graph has the same length as the control trend line graph.

[0066] Step 3. According to the following formula, calculate the similarity between the target trend line graph and each control trend line graph based on the cut-off target trend line graph and the control trend line graph.

[0067] ; Among them, is the similarity between the target trend line and the control trend line, is the length of the target trend line, is the disease index of the point with abscissa i in the target trend line after cutting is completed, is the disease index of the point with abscissa i in the control trend line.

[0068] Step 4: If the length of the target trend line is equal to the control trend line, calculate the similarity between the target trend line and the control trend line through the following formula.

[0069] ; Among them, is the similarity between the target trend line and the control trend line, is the length of the target trend line, is the disease index of the point with abscissa i in the target trend line, is the disease index of the point with abscissa i in the control trend line.

[0070] S110. Determine the disease development trend corresponding to the rare disease patient according to the similarity.

[0071] In the embodiment of the present application, the disease development trend corresponding to the rare disease patient refers to the disease development trend within a preset time period in the future.

[0072] Specifically, the disease development trend corresponding to the rare disease patient is determined through the following steps: Step 1: If the maximum value of the similarity is greater than or equal to the preset similarity, determine the actual disease development trend corresponding to the control trend line with the maximum similarity as the disease development trend corresponding to the standard rare disease patient.

[0073] Step 2: If the maximum value of the similarity is less than the preset similarity and there is a target point with a tangent slope of 0 in the target trend line, calculate the difference between the disease index corresponding to the target point with the latest time and the disease index of the point with the latest time in the target trend line.

[0074] Here, if the maximum value of the similarity is less than the preset similarity, the target trend line is determined as the control trend line, which can increase the number of control trend lines and improve the prediction accuracy.

[0075] Step 3: If the difference is greater than 0, the disease development trend corresponding to the rare disease patient is a trend of improvement in the condition.

[0076] In the embodiments of the present application, if the difference is greater than the first preset difference, the disease development trend corresponding to the rare disease patient is a rapid improvement trend; if the difference is greater than 0 and less than the first preset difference, the disease development trend corresponding to the rare disease patient is a slow improvement trend.

[0077] Step Four: If the difference is less than 0, the disease development trend corresponding to the rare disease patient is a deterioration trend.

[0078] In the embodiments of the present application, if the difference is less than the second preset difference, the disease development trend corresponding to the rare disease patient is a rapid deterioration trend; if the difference is less than 0 and greater than the second preset difference, the disease development trend corresponding to the rare disease patient is a slow deterioration trend.

[0079] Step Five: If the difference is equal to 0, the disease development trend corresponding to the rare disease patient is a stable trend.
