[0043] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments, and they should not be understood as limitations on the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of the present invention, it should be understood that the terms used are only for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0044] The following combination Figures 1-8 The present invention describes a method for constructing a Parkinson's disease efficacy prediction model and an STN-DBS surgery decision support system. It should be noted that the method for constructing a Parkinson's disease efficacy prediction model provided by the present invention can be executed by any network-side device or terminal-side device that meets the technical requirements, such as a device for constructing a Parkinson's disease efficacy prediction model.
[0045] Figure 1 Schematic diagram of the method for constructing a Parkinson's disease efficacy prediction model provided by the present invention. Figure 1 The present invention provides a method for constructing a Parkinson's disease efficacy prediction model, which may include:
[0046] Step S110: Obtain clinical information, motor function scores, emotional scores, and cognitive function scores of the target group before and after STN-DBS treatment, wherein the target group includes a Parkinson's disease patient group. In this embodiment, clinical information, motor function scores, emotional scores, and cognitive function scores of the target group are obtained before STN-DBS treatment, and one year and five years after STN-DBS treatment, which helps the Parkinson's disease efficacy prediction model understand the relationship between clinical information, motor function scores, emotional scores, cognitive function scores, and the long-term and short-term efficacy of STN-DBS treatment.
[0047] This example used 496 PD patients who underwent bilateral DBS as the target population and collected their clinical information, motor function scores, mood scores, and cognitive function scores. Inclusion criteria included: (1) meeting the 2006 diagnostic criteria for primary PD by the Movement Disorders and PD Group of the Chinese Medical Association's Neurology Branch; (2) Parkinson's disease duration >4 years; (3) significant decline in drug efficacy, or symptom fluctuations such as "on-off" phenomena, dyskinesias, and impact on the patient's quality of life; (4) patients and their families signed informed consent. Exclusion criteria included: (1) patients with contraindications to DBS; (2) patients with moderate or severe cognitive impairment or persistent severe mental disorders; (3) patients with severe brain atrophy or diffuse cerebral ischemic lesions as shown by cranial MRI; and (4) patients who were unable to complete postoperative follow-up.
[0048] Specifically, clinical information includes any one of the following or any combination thereof: disease course, age at surgery, age at onset, levodopa equivalent dose (LED), and levodopa medication improvement rate, where levodopa medication improvement rate = (baseline score before medication - lowest score after medication) / baseline score before medication × 100%.
[0049] Motor function scores include those obtained using the Unified Parkinson's Disease Rating Scale (UPDRS). The Unified Parkinson's Disease Rating Scale is an internationally recognized Parkinson's disease symptom rating scale consisting of four subscales (UPDRS-I, II, III, and IV). Higher scores indicate more severe symptoms. UPDRS-I is a mental, behavioral, and emotional score that assesses the patient's mental state. It includes 1 to 4 items with a total score of 0 to 16, with higher scores indicating more severe symptoms. UPDRS-II is a score for activities of daily living, encompassing 13 items such as writing, dressing, personal hygiene, and turning over, with a total score of 0 to 52. Higher scores indicate poorer daily living abilities and a greater inability to care for oneself. UPDRS-III is a motor examination score, encompassing 14 items such as facial expression, tremor, rigidity, bradykinesia, postural disturbances, and gait examination, with a total score of 0 to 56. Higher scores indicate more severe somatic motor symptoms. UPDRS-IV is a motor complication score, assessing complications such as dyskinesia and symptom fluctuations, with a total score of 0 to 23. A score of >1 on item 32 indicates dyskinesia in patients with Parkinson's disease; a score of 1 on item 36 indicates on-off switching. The UPDRS uses a 0-4 scale for a total score of 199. Scores for each component are weighted to create a total score, with higher scores indicating more severe disease.
[0050] The mood score includes the first mood score obtained by the Hamilton Anxiety Rating Scale (HAMA) and the second mood score obtained by the Hamilton Depression Rating Scale (HAMD).
[0051] The primary emotion score includes scores for 14 domains: anxious mood, tension, fear, insomnia, cognitive function (also known as memory and attention impairment), depressed mood, somatic anxiety, cardiovascular symptoms, respiratory symptoms, gastrointestinal symptoms, genitourinary symptoms, autonomic nervous system symptoms, and behavioral performance during the interview. All items in the HAMA are scored on a 5-point scale ranging from 0 to 4, with the following levels being: 0 (no symptoms); 1 (mild); 2 (moderate); 3 (severe); and 4 (extremely severe). The total HAMA score accurately reflects the severity of anxiety symptoms. It can be used to assess the severity of anxiety symptoms in patients with anxiety and depressive disorders and to evaluate the effectiveness of various medications and psychological interventions. According to data provided by the Chinese Scale Collaborative Group: a total score ≥29 indicates possible severe anxiety; ≥21 indicates significant anxiety; ≥14 indicates definite anxiety; ≥7 indicates possible anxiety; and ≤7 indicates no anxiety symptoms.
[0052] The secondary mood score includes 24 items, including depression, guilt, suicidal thoughts, difficulty sleeping, somatic anxiety, general symptoms, and insight. Each item is scored from 0 to 2 or 0 to 4 to indicate severity. The sum of the scores is the HAMD score. A total score of 35 or more indicates severe depressive symptoms; a total score of 30 or more and less indicates moderate depressive symptoms; a total score of 20 or more and less indicates mild or moderate depressive symptoms; a total score of 8 or more and less than 20 indicates no significant depressive symptoms; and a total score of less than 8 indicates no depressive symptoms.
[0053] The cognitive function scores included the first cognitive function score obtained by the Mini-Mental State Examination (MMSE) and the second cognitive function score obtained by the Montreal Cognitive Assessment (MoCA).
[0054] The first cognitive function score includes scores for five domains: orientation, attention, memory, language ability, and executive function.
[0055] MMSE scale criteria: (1) Cognitive dysfunction: The maximum score is 30 points, a score of 27-30 points is normal, and a score of <27 points is cognitive dysfunction; (2) Dementia classification criteria: illiteracy ≤ 17 points, primary school level ≤ 20 points, secondary school level (including technical secondary school) ≤ 22 points, university level (including junior college) ≤ 23 points; (3) Dementia severity grading: mild MMSE ≥ 21 points, moderate MMSE 10-20 points, severe MMSE ≤ 9 points. The MMSE scale examines the patient's cognitive level by evaluating the following five aspects: (1) Orientation: Orientation refers to a person's ability to recognize time, place, people, and their own status. In the scale examination, this item is reflected in questions such as "date, season, province, city". (2) Memory: Memory is the ability to remember, retain, re-recognize, and reproduce the content and experience reflected by objective things. In the memory examination items, the doctor usually tells the subject that several questions will be asked to check the memory. The doctor says the names of three unrelated things and then asks the subject to repeat them. (3) Attention and calculation ability: Attention refers to the ability of a person's mental activities to be directed and focused on something. In this part of the examination, the doctor will ask the subject to subtract 7 from 100, then subtract 7 again, and so on for 5 times. (4) Recall ability: In the examination of recall ability, the doctor will ask the subject to repeat the names of three unrelated things that the doctor had previously said to test the subject's recall ability. (5) Language ability: Language ability refers to the ability to master language. This ability is manifested in the ability to speak or understand unprecedented, grammatical sentences, the ability to distinguish ambiguous sentences, the ability to distinguish sentences with the same surface form but different actual meanings or sentences with different surface forms but similar actual meanings, and the ability to use language skills such as listening, speaking, reading, writing and translation. In the MMSE scale, language ability is evaluated in the following six aspects: (1) Naming ability: the doctor will take out some cards and objects for the subject to see, and ask the subject to say the name of the object shown on the card; (2) Retelling ability: the doctor will say a sentence and ask the subject to pay attention to the sentence and repeat it; (3) Three-step command: the doctor will ask the subject to complete a series of actions according to the doctor's order; (4) Reading ability: the doctor will provide a card and ask the subject to read the text on the card and complete the action according to the text requirements; (5) Writing ability: the doctor will ask the subject to write a complete sentence spontaneously; (6) Structural ability: the doctor will provide a graphic and ask the subject to copy it.
[0056] The second cognitive function score includes scores for eight subdomains: visual-spatial and executive ability, naming ability, attention, calculation ability, language ability, abstract thinking ability, delayed memory, and orientation.
[0057] The MoCA scale has a maximum score of 30, with scores of 26 or higher considered normal, 18-26 mild cognitive impairment (MCI), 10-17 moderate, and less than 10 severe. MCI patients score approximately 22 (19-25), and Alzheimer's patients score between 11 and 21. If the subject has ≤12 years of education (high school level), 1 point can be added to the score, but the total score cannot exceed 30. If the patient is illiterate or has a low level of education, the basic test can be used.
[0058] Step S120: Based on the clinical information, motor function scores, emotional scores, and cognitive function scores of the target group before and after STN-DBS treatment, characteristic variables related to the efficacy of STN-DBS are obtained using factor regression analysis, where the factor regression analysis method includes univariate COX regression analysis and multivariate COX regression analysis.
[0059] In one embodiment, step S120 may include:
[0060] Based on the clinical information, motor function scores, emotional scores, and cognitive function scores of the target group, univariate COX regression analysis was performed, and the factors corresponding to the probability value P1 < 0.05 in the univariate COX regression analysis results were regarded as the first potential risk factors related to the efficacy of STN-DBS;
[0061] According to the first potential risk factor related to the efficacy of STN-DBS, the multivariate COX regression analysis method was used. The first potential risk factor corresponding to the probability value P2<0.05 in the multivariate COX regression analysis results was used as the second potential risk factor related to the efficacy of STN-DBS, and at the same time as the characteristic variable related to the efficacy of STN-DBS.
[0062] After the univariate Cox regression analysis, the data results may be affected by multiple other factors. Therefore, the present embodiment further performs a multivariate Cox regression analysis to eliminate the influence of multiple factors on the surgical efficacy at the same time.
[0063] Table 1 shows the results of a univariate COX regression analysis of preoperative risk factors (i.e., clinical information, motor function scores, emotional scores, and cognitive function scores of the target group before and after STN-DBS treatment) in this embodiment, with disease duration, levodopa equivalent dose, motor function score, levodopa medication improvement rate, emotional score, and cognitive function score as the first potential risk factor. Table 2 shows the results of a multivariate COX regression analysis based on the results of the univariate COX regression analysis in this embodiment, with disease duration, motor function score, levodopa medication improvement rate, and emotional score as the second potential risk factor, as characteristic variables related to the efficacy of STN-DBS.

[0068]
[0069] Step S130: Based on the characteristic variables related to the STN-DBS efficacy, elastic network machine learning is used to construct a Parkinson's disease efficacy prediction model, wherein the Parkinson's disease efficacy prediction model is displayed in the form of a nomogram. The Parkinson's disease efficacy prediction model can be used to obtain the degree of influence of the characteristic variables related to the STN-DBS efficacy on the STN-DBS treatment efficacy.
[0070] In one embodiment, step S130 may include:
[0071] The ROC curve was used to evaluate the prediction accuracy of the Parkinson's disease efficacy prediction model;
[0072] The calibration curve and multiple sampling comparisons were used to evaluate the prediction results of the Parkinson's disease efficacy prediction model and the probability of the actual surgical improvement rate to verify the accuracy and consistency index of the Parkinson's disease efficacy prediction model as conditions to determine whether the predicted effect of the Parkinson's disease efficacy prediction model on the improvement rate is consistent with the actual improvement rate.
[0073] In this example, the disease duration, motor function score, levodopa medication improvement rate, and mood score of the target population are used as characteristic variables related to the efficacy of STN-DBS. A training set and a validation set are divided, and a Parkinson's disease efficacy prediction model is constructed using the elastic network in machine learning. The elastic network has high scalability and elasticity, as well as a flexible network topology, which can ensure the prediction accuracy, high performance and stability, and rapid deployment capability of the Parkinson's disease efficacy prediction model. During the model construction process, cross-validation, specificity and sensitivity testing are performed on the training set and validation set, and the effectiveness of the model is verified using calibration curves and ROC curves (see Figure 2-5 ), in order to improve the prediction accuracy of the Parkinson's efficacy prediction model, and in this embodiment, the constructed Parkinson's efficacy prediction model is finally displayed in the form of a nomogram, such as Figure 6 shown.
[0074] The present invention provides a method for constructing a Parkinson's disease efficacy prediction model and an STN-DBS surgery decision-making support system. Based on clinical information, motor function scores, emotional scores, cognitive function scores and other data from a target group before and after STN-DBS treatment, combined with factor regression analysis, a high-precision Parkinson's disease efficacy prediction model is constructed. This model can achieve accurate preoperative screening of Parkinson's disease patients for deep brain stimulation of the subthalamic nucleus, effectively improving the accuracy and efficiency of making individualized surgical decisions for Parkinson's disease patients with different clinical symptoms.
[0075] The Parkinson's efficacy prediction model obtained by the method for constructing a Parkinson's efficacy prediction model provided by the present invention can be used to assist in STN-DBS surgical decision-making. The clinical information, motor function score, emotional score, cognitive function score, etc. of the subject before STN-DBS treatment are input into the Parkinson's efficacy prediction model. According to the degree of influence of characteristic variables related to STN-DBS efficacy obtained by the Parkinson's efficacy prediction model on the STN-DBS treatment efficacy, the degree of surgical improvement that the subject may obtain after STN-DBS treatment can be calculated based on the clinical information, motor function score, emotional score, and cognitive function score of the subject before STN-DBS treatment, thereby assisting in deciding whether the subject needs to undergo STN-DBS treatment.
