[0002] Depression is an affective mental disorder, mainly manifested by significant and persistent low mood. Its core characteristics are reduced behavior and loss of pleasure. The main clinical manifestations include: significant and persistent low mood, slow thinking, reduced spontaneous speech, inattention, decreased learning and work ability, difficulty in interpersonal communication, etc.; often accompanied by obvious tension, anxiety and irritability, as well as self-blame, self-guilt, and negative suicidal ideas or behaviors.
[0003] For example, Chinese patent CN113693584A discloses a method for selecting depression symptom predictor variables, a computer device and a storage medium. The method of the present invention comprises the following steps: investigating depression patients and normal controls, collecting general information, Hamilton Depression Rating Scale scores and resting functional magnetic resonance imaging scan data; collecting the above information again after the depression patients receive treatment and the individual clinical symptoms are relieved; processing the resting functional magnetic resonance imaging scan data to obtain a DC brain map; based on the obtained DC brain map, analyzing the changes in brain functional activities of depression patients before and after treatment, and finding variables that can characterize the relief of depression symptoms. A computer device for implementing the above method is further provided. It can provide objective support for the prediction of early clinical efficacy of depression, reduce the social burden of the disease, and has a good application prospect.
[0004] For example, Chinese patents CN111513735A and CN115714002A disclose a method for diagnosing / early warning of depression. However, for patients with depression, there is no good auxiliary diagnosis method for problems that arise during their subsequent treatment and rehabilitation processes. Therefore, the present invention provides a depression diagnosis system based on clinical phenotype data. Summary of the invention
[0005] The purpose of the present invention is to provide a depression diagnosis system based on clinical phenotype data, which solves the existing problems by collecting information such as users' emotional curves and questionnaire answer monitoring, and combining it with analysis and processing of historical data.
[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0007] The present invention is a depression diagnosis system based on clinical phenotype data, comprising:
[0008] A data collection unit, the data collection unit is used to obtain the user's health index based on the emotion curve and questionnaire answer monitoring;
[0009] A data processing unit, which is used to obtain the real-time warning ratio according to the sentiment curve and perform warning analysis;
[0010] When the real-time warning ratio exceeds the reasonable fluctuation range for T1 consecutive days, or the number of days that exceed the reasonable fluctuation range within T0 consecutive days exceeds T11, an early warning signal is generated, and T1, T0, and T11 are preset values;
[0011] When the real-time warning ratio is greater than the preset value R1, and the health index is greater than the preset value R2, a warning signal is generated;
[0012] The data processing unit transmits the early warning prompt signal to the early warning prompt terminal.
[0013] Furthermore, the data collection unit performs the following steps when acquiring the user health index:
[0014] Step S1: Obtain the user's emotional curve during hospitalization, extract the number of times the user is depressed every day and the duration of depression every day according to the emotional curve, mark the number of times the user is depressed every day as Di, and mark the duration of depression every day as Si, i=1, 2, 3, ..., n, where n is a positive integer;
[0015] Step S2: Calculate the slope of the sentiment curve for every two consecutive days, and intercept the slope at The dates corresponding to the sentiment curve within the interval are marked as normal fluctuation intervals, and the remaining dates are marked as abnormal fluctuation intervals. k1 and k2 are preset values;
[0016] Step S3: sorting the normal fluctuation intervals and abnormal fluctuation intervals in chronological order, marking the health index 1 of the user on the corresponding date as JK1 or JK2 or JK3 or JK4 or JK5 according to the distribution and slope of the normal fluctuation intervals and abnormal fluctuation intervals after sorting, and the health index 1 is obtained according to the slope of the emotion curve;
[0017] Step S4: When the health index 1 is less than X1, the number of times the user is depressed every day Di and the duration of depression every day Si are obtained. If Di or Si shows a downward trend within the continuous time X2, the health index 2 is marked as ZK1, and X1 and X2 are preset values; otherwise, the health index 2 is marked as ZK2, and the health index 2 is obtained according to the slope of the emotion curve;

[0023] Furthermore, the health index 1 is obtained in the following manner:
[0024] If there is no abnormal fluctuation interval before or after the normal fluctuation interval, the user's health index 1 is marked as JK1, and the health index 1 JK1 is the average of the maximum slope and the minimum slope of the normal fluctuation interval of the emotion curve;
[0025] If there is an abnormal fluctuation interval before the normal fluctuation interval, and the slope of the abnormal fluctuation interval is greater than k2, the user's health index 1 is marked as JK2, and the health index 1 JK2 is the average of the maximum slope of the abnormal fluctuation interval and the maximum slope of the normal fluctuation interval;
[0026] If there is an abnormal fluctuation interval after the normal fluctuation interval, and the slope of the abnormal fluctuation interval is less than k1, the user's health index 1 is marked as JK3, and the health index 1 JK3 is the average of the maximum slope and the minimum slope of the emotion curve of the abnormal fluctuation interval;
[0027] If there is only an abnormal fluctuation interval, and the slope of the abnormal fluctuation interval is less than k1, the user's health index 1 is marked as JK4, and the health index 1 JK4 is the median of the slope of the emotion curve;
[0028] Otherwise, the user's health index 1 is marked as JK5, and the health index 1 JK5 is X3 times the maximum value of the slope of the emotion curve, where X3 is a preset value.
[0029] Furthermore, the health index 2 is obtained in the following manner:

[0031] Health index 2 ZK1=(SJ1-SJ2) / (DJ1-DJ2);
[0032] Health Index 2 ZK2: Take a maximum value and a minimum value from the number of times the user is depressed, and mark them as Dmax and Dmin respectively; take a maximum value and a minimum value from the duration of the user's depression, and mark them as Smax and Smin respectively;
[0033] Health index 2 ZK2= (Smax-Smin) / (Dmax-Dmin).
[0034] Further, the data processing unit performs the following steps when obtaining the warning ratio according to the sentiment curve:
[0035] Intercept the curve between the line segment y=Y1 and the line segment y=Y2 in the emotion curve and mark it as the warning line. Y1 and Y2 are preset values, and Y1<Y2;
[0036] Get the total length of the warning line and mark it as Ly;
