[0002] Mental illness refers to clinical manifestations characterized by varying degrees of impairment in cognitive, emotional, volitional, and behavioral mental activities, resulting from brain dysfunction under the influence of various biological, psychological, and social factors. Most patients with mental illness experience a prolonged course of illness, fluctuating symptoms, and are prone to relapse, requiring consistent and regular medication to control symptoms and prevent relapse.

[0003] Quetiapine, as a commonly used drug for mental illness, is commonly used for various types of schizophrenia. It is not only effective for the positive symptoms of schizophrenia, but also has a certain effect on the negative symptoms. It can also alleviate the emotional symptoms related to schizophrenia such as depression, anxiety and cognitive deficits.

[0004] Due to differences in dietary habits, living environments, etc. among people in different geographical regions, their drug metabolism abilities may be different. The same drug dose may have different efficacy (drug concentration) for patients in different regions. The same is true for quetiapine. The same drug dose of quetiapine often has certain differences in efficacy for patients with mental illness in different geographical regions. Therefore, in order to ensure that the drug effect meets the standard, to reduce the harm of excessive drug concentration to the patient's body (including drug poisoning), and to reduce the recurrence of the disease or unsatisfactory disease control effect caused by insufficient drug concentration, it is urgent to develop a method for determining the reference range of quetiapine drug concentration based on regional differences, so as to determine a quetiapine drug concentration reference range that is more suitable for the geographical region.

[0032] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0034] In order to ensure that the drug effect of quetiapine in different regions meets the standard, this application provides a method for determining the reference range of quetiapine drug concentration based on regional differences, see Figure 1 , the method comprising:

[0035] S1. Divide geographical areas;

[0036] S2. For each divided area, perform steps S21 to S25 respectively.

[0037] S21. Obtain the patient's psychiatric rating scale results and electroencephalogram information before taking quetiapine;

[0038] S22. Obtain the patient's psychiatric rating scale assessment results, electroencephalogram (EEG) information, blood drug concentration information, and adverse reaction information after taking different drug doses;

[0039] S23. Determine the appropriate blood drug concentration range for each patient;

[0040] S24. Obtaining a regional total blood drug concentration range based on the blood drug concentration range applicable to each patient in the region;

[0041] S25. The confidence interval in the total range of regional blood drug concentration that is greater than the preset threshold is taken as the reference range of quetiapine drug concentration in the region.

[0042] In this embodiment, geographical division is performed based on natural and cultural characteristics, such as geographical location, natural environment, cultural characteristics, and eating habits.

[0043] For each geographical area, the psychiatric rating scale evaluation results and electroencephalogram (EEG) information of several patients who did not use quetiapine were obtained. For patients who did not use quetiapine, the psychiatric rating scale test was performed to obtain the evaluation results, and the EEG test was performed to obtain the EEG information, which was called the EEG information before drug use.

[0044] Given existing drug instructions, the dosage can be adjusted appropriately based on patient response, for example, exceeding or falling below the instructions. Here, quetiapine is administered at a daily dose of 300-450 mg. This dosage can be adjusted to 150-750 mg daily based on the patient's clinical response and tolerance. The 300-450 mg dosage can be divided into four different doses: 300 mg, 350 mg, 400 mg, and 450 mg. Patients are not required to take each dose according to the different dosages; this can be determined based on specific circumstances. For example, if a patient responds to 150 mg, they may be tested with 450 mg.

[0045] For the above patients, the psychiatric rating scale evaluation results, electroencephalogram information, blood drug concentration information, and adverse reaction information were obtained after the patients took the drugs at different doses.

[0046] The blood collection time corresponding to blood drug concentration information can refer to existing relevant guidelines. For example, quetiapine is a drug with an elimination half-life of less than 12 hours. For psychotropic drugs with an elimination half-life of 4-12 hours, the TDM blood collection time and the last medication dose time should be relatively fixed to obtain more stable TDM results. In other words, the medication and blood collection times should be relatively fixed to reduce diurnal fluctuations in TDM results.

[0047] In this embodiment, the patient's blood is processed as follows:

[0048] Collect 3-5 ml of whole blood using a red-capped glass tube without any additives and centrifuge at 3500 rpm for 10 minutes. Liquid chromatograph mobile phase A: Add 1 ml each of Zhejiang Disai Mobile Phase Additives A1 and A2 to 1000 ml of deionized water and mix ultrasonically. Mobile phase B: Add 1 ml of Zhejiang Disai Mobile Phase Additive B1 to 1000 ml of methanol and mix ultrasonically. Instrument-related procedures: ① Tune and calibrate the mass spectrometer Q1 and Q3 for positive ions; ② Optimize compound parameters; ③ Establish an LC-MS method; ④ Create a sampling list. Place 50 μl of sample serum (standard, quality control) into a centrifuge tube, add 150 μl of precipitant and internal standard solution, vortex mix for 5 minutes, centrifuge at 15,000 rpm for 10 minutes, and add 10 μl of the supernatant to 100 μl of diluent. Mix thoroughly, then place in a sample plate for analysis. A KLP-SPZ-004 (4.0 μm, 50 mm*2.0 mm) chromatographic column was used, and gradient elution was adopted: 0-0.3 min 20% B, 0.3-1.0 min 70% B, 1.0-2.6 min 90% B,

[0049] 20% B for 2.6-3.0 min, flow rate 0.6 ml / min. Mass spectrometry detection was performed using an electrospray ionization source in positive ion monitoring mode. The mass spectrometry parameters for quetiapine were: Q1Mass: 384.20 Da, Q3Mass: 221.20 Da, Dwell Time: 10.00 msec, Declustering Potential DP: 90.00 V, Collision Voltage CE: 50.00 eV, and Exit Voltage CXP: 18.00 V. The processing included generating a quetiapine concentration standard curve.

[0050] For EEG information, the time corresponding to the collection of the patient's EEG information can be almost equal to the time corresponding to the blood drug concentration information, or the EEG information can be sleep EEG information. Changes in brain waves are one of the biological bases of depression.

[0051] The blood drug concentration range applicable to each patient requires a lower limit and an upper limit. The upper limit can be the lowest concentration at which adverse reactions occur, or the upper threshold concentration, which is mainly obtained by calculating the expected dose-related blood drug concentration at the maximum dose in the instructions. The minimum dose at which the condition improves is the lower limit. As an example, based on the severity determined by the BPRS scale, the minimum dose is used according to the drug instructions, and the patient is evaluated using the PANSS scale every two weeks. If the condition improves, the drug concentration is tested and recorded as a statistical low value data.

[0052] Here, the S23 is specifically:

[0053] The blood drug concentration of each patient is detected. Specifically, when the first comparison result exceeds the first requirement or the second comparison result exceeds the second requirement, the blood drug concentration of each patient is detected. For each patient, if the patient has an adverse reaction (adverse reaction information is none), the corresponding blood drug concentration is determined to be a blood drug concentration that is not suitable for the patient; when the patient does not have an adverse reaction, the first comparison result is obtained by comparing the patient's psychiatric rating scale evaluation result before quetiapine and the patient's psychiatric rating scale evaluation result after medication, and the second comparison result is obtained by comparing the patient's electroencephalogram information before quetiapine and the patient's electroencephalogram information after medication. If the first comparison result exceeds the first requirement and / or the second comparison result exceeds the second requirement, the blood drug concentration is determined to be a blood drug concentration suitable for the patient, otherwise, the blood drug concentration is determined to be a blood drug concentration that is not suitable for the patient. The setting of the first requirement and the second requirement is not limited. For example, it can be better than the psychiatric rating scale evaluation result / electroencephalogram information without quetiapine, or the degree of improvement can be required, for example, the difference in the evaluation results needs to exceed a certain value.

[0054] It is understandable that in patients with depression, alpha waves, beta waves, theta waves, asymmetry of the left and right hemispheres, abnormalities in certain neural network connections, etc. are often reflected in the EEG information, but not all people will have changes in EEG before and after the action of quetiapine, and not all people will see rapid improvement in assessment before and after the action of quetiapine. For example, in the early stages, there may be improvement in sleep. Therefore, as long as only one of the assessment results and EEG information is effective, accuracy can be guaranteed.

[0055] In this embodiment, S21 further includes obtaining basic patient information, including liver and kidney function information, thyroid function information, basal metabolic information, and body temperature information. Accordingly, S24 specifically includes eliminating data from patients with abnormal basic information and obtaining a regional total blood drug concentration range based on the blood drug concentration range applicable to each patient in the region with normal basic information. This design improves the accuracy of determining the reference range.

[0056] If any of the liver and kidney function information, thyroid function information, basal metabolic information, and body temperature information is abnormal, the basal information is considered abnormal. If any liver and kidney function indicator is not within the normal range, the liver and kidney function is considered abnormal. If any thyroid function indicator is not within the normal range, the thyroid function is considered abnormal. If the basal metabolic information is not within the metabolic range for the patient's age, the basal metabolic rate is considered abnormal. If the body temperature is not within the normal range, it is usually a fever, which is likely to affect drug metabolism and is considered abnormal.

[0057] In the present embodiment, the determination method further comprises step S3, obtaining the regional characteristics of each region, obtaining the quetiapine reference range recommended by the guideline, and analyzing the influence of the regional characteristics on the quetiapine drug concentration reference range in the region based on the regional characteristics of the region, the quetiapine reference range recommended by the guideline, and the quetiapine drug concentration reference range in the region of each region. Regional characteristics, for example, include dietary characteristics, climatic characteristics, and environmental characteristics, for example, including that people in the region are susceptible to diseases, etc. It is not limited to which guideline, nor is it limited to only one guideline. The analysis result can usually be that a certain factor has a positive impact, no impact, or a negative impact. Specifically, the output can also include the degree of impact. Based on the analysis result, its result can be used as a reference to adjust the diet and be used as a reference when the regional reference range for other related drugs is determined.

[0058] The S3 can be implemented by an analytical model, for example, by defining that each factor has a linear relationship (or other relationship) with the blood drug concentration, integrating all information, comprehensively fitting all factors according to the reference range of quetiapine drug concentration in the region, and calculating the linear coefficient of each factor.

[0059] Said S2 also includes calculating the median, mean and standard deviation of the blood drug concentration of the total range of regional blood drug concentration or the reference range of quetiapine drug concentration in the region; said analysis of the impact of regional characteristics on the reference range of quetiapine drug concentration in the region is also based on the median, mean and standard deviation of the blood drug concentration of the total range of regional blood drug concentration or the reference range of quetiapine drug concentration in the region.

[0060] In a preferred embodiment, in S3, the blood concentration information and medication dosage of each non-excluded patient are also obtained, and the impact is analyzed accordingly.

[0061] See also Figure 2 This embodiment also provides a system for determining a reference range of quetiapine drug concentration based on regional differences, including a division module, an acquisition module, and a range determination module.

[0062] The division module is used to divide geographical areas.

[0063] The acquisition module is used to obtain the patient's psychiatric rating scale evaluation results and electroencephalogram information before taking quetiapine, and is used to obtain the patient's psychiatric rating scale evaluation results, electroencephalogram information, blood drug concentration information, and adverse reaction information after taking different doses of the drug.

[0064] The range determination module is used to determine the blood drug concentration range applicable to each patient, to obtain the total regional blood drug concentration range based on the blood drug concentration range applicable to each patient in the region, and to take the interval in the total regional blood drug concentration range with a confidence level greater than a preset threshold as the reference range of quetiapine drug concentration in the region.

[0065] In this embodiment, the acquisition module is also used to obtain basic information of the patient, which includes liver and kidney function information, thyroid function information, basal metabolic information, and body temperature information.

[0066] The range determination module is used to determine the applicable blood drug concentration range for each patient, and to obtain the regional total blood drug concentration range based on the applicable blood drug concentration range for each patient in the region. Specifically, it is used to eliminate the data of patients with abnormal basic information, and to obtain the regional total blood drug concentration range based on the applicable blood drug concentration range for each patient with normal basic information in the region.

[0067] The determination system further includes an analysis module for analyzing the impact of regional characteristics on the reference range of quetiapine drug concentration in the region based on the regional characteristics of the region, the reference range of quetiapine recommended by the guidelines, and the reference range of quetiapine drug concentration in the region of each region.

[0068] Here, the determination system further includes a calculation module for calculating the median, mean, and standard deviation of the blood drug concentration of the regional total blood drug concentration range or the regional reference range of quetiapine drug concentration. The analysis module analyzes the impact of regional characteristics on the regional reference range of quetiapine drug concentration based on the median, mean, and standard deviation of the blood drug concentration of the regional total blood drug concentration range or the regional reference range of quetiapine drug concentration, and also based on regional characteristics of the region, the quetiapine reference range recommended by the guidelines, and the regional reference range of quetiapine drug concentration in each region.

[0069] Here, the division module is specifically used to divide geographical regions into several regions according to natural and human characteristics.

[0070] Here, the range determination module is used to determine the blood drug concentration range applicable to each patient, specifically for: detecting the blood drug concentration of each patient; determining the blood drug concentration that is not applicable to the patient when the patient has adverse reactions; comparing the psychiatric rating scale evaluation results of the patient before using quetiapine and the psychiatric rating scale evaluation results of the patient after taking the drug to obtain a first comparison result, and comparing the electroencephalogram information of the patient before using quetiapine and the electroencephalogram information of the patient after taking the drug to obtain a second comparison result, when the patient does not have adverse reactions, and determining the blood drug concentration that is applicable to the patient when the first comparison result exceeds the first requirement and / or the second comparison result exceeds the second requirement; and determining the blood drug concentration that is not applicable to the patient when the first comparison result does not exceed the first requirement and the second comparison result does not exceed the second requirement.
