Description

Technical Field

[0001] This invention relates to the technical field of injury models, and in particular to an artificial intelligence-based method and system for constructing a mouse model of multiple injuries for dynamic evaluation. Background Technology

[0002] With the high incidence of multiple injuries in trauma research and their complex physiological cascade responses, establishing scientific, controllable, and dynamically assessable animal models has become an urgent need for basic and translational research. In practical applications, traumatic brain injury combined with thoracic and abdominal injuries is often accompanied by multiple systemic imbalances, such as autonomic nervous system dysfunction, circulatory and respiratory dysfunction. The early mortality risk in individuals with severe traumatic brain injury is highly correlated with multiple parameters such as lactate levels, base excess, and injury scores, which places higher demands on the dynamic grading of experimental animal models and the scientific determination of critical time windows. Traditional single injury models are no longer sufficient to reflect the complex evolution and cascade mechanisms of multiple injuries in the physiological process.

[0003] Currently, existing animal model technologies suffer from three main problems. First, the controllability of injury is limited. Traditional methods such as free-fall impact and liver / spleen puncture rely solely on mechanical parameters to determine injury intensity, failing to establish a linear correlation between physiological responses and input parameters. This leads to inaccurate model grading and poor repeatability. Brain and thoracic / abdominal injuries are often induced separately, neglecting the essential characteristics of multiple injuries in terms of cross-compartmental biomechanical responses and physiological coupling. Second, dynamic monitoring and multimodal integration mechanisms are lacking. Existing models often rely on endpoint behavioral tests (such as the water maze and rotarod test) or single physiological parameters, making it difficult to achieve real-time continuous monitoring of key signals such as intracranial pressure, blood pressure, and respiratory rate. This results in missed opportunities for critical processes such as shock compensation and secondary brain injury. Furthermore, behavioral and tissue indicators are influenced by subjective interpretation, making it difficult to quantify complex injury dynamics. Third, there are significant deficiencies in cross-system interactive modeling and individualized adaptation. Traditional finite element models and stress wave propagation simulations are mostly applied to large individuals, with limited accuracy in simulating individual structural differences and cross-compartmental mechanical coupling in mice, making it difficult to achieve cascade responses and accurate modeling of multiple injuries.

[0004] While artificial intelligence (AI) technology has already assisted decision-making in some areas, dynamic, real-time intelligent grading in animal models remains a gap. Existing scoring systems or decision-making models based on static data are mostly used for single-instance risk prediction, lacking the ability to fuse dynamic physiological signals and incremental learning. Issues such as inconsistent multi-center data standards and insufficient model generalization ability limit the high versatility and consistency of intelligent grading tools in animal experiments. Current technologies urgently need breakthroughs in areas such as damage controllability, dynamic monitoring, multimodal data fusion, cross-system interaction, and intelligent grading. How to properly address these issues has become a pressing issue for the industry. Summary of the Invention

[0025] Output real-time updated severity scores for multiple injuries and / or early warning signals.

[0026] In one embodiment, it also includes:

[0027] Before injury, mice were subjected to miniature CT scans to obtain individual anatomical atlases of mice, including skull thickness, brain volume, and thoracic structure.

[0028] The impact location and angle of the traumatic brain injury are adjusted based on the anatomical atlas to reduce the injury dispersion caused by individual differences.

[0029] The propagation path of mechanical stress from the thoracic cavity to the brain is simulated using a finite element model, and the parameters of thoracic and abdominal injuries are calibrated accordingly to achieve the predetermined degree of secondary brain injury.

[0030] According to a second aspect of the present invention, an artificial intelligence dynamic assessment system for constructing a mouse multiple injury model is provided, comprising:

[0031] The injury module is used to apply controlled impacts to the brain of mice to cause brain damage and to introduce controlled trauma to the chest and abdomen to simulate thoracic and abdominal injuries.

[0033] The analysis module is used to input the physiological data into an artificial intelligence algorithm model, perform time-series analysis and cross-system data fusion, assess the severity of the injury in the injured mouse in real time, and generate corresponding assessment results.

[0034] The grading module is used to grade the severity of the injury based on the assessment results, and to establish a corresponding mouse model of multiple injuries to the brain and chest and abdomen.

[0039] In summary, this invention provides a method and system for constructing a mouse model of multiple injuries using artificial intelligence for dynamic assessment.

The technical solution of this application, through controlled injury and real-time multimodal physiological monitoring, achieves controllable and highly repeatable classification of the mouse model of multiple injuries to the cranium and chest / abdomen.

It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it.

[0053] like Figure 1 As shown, this invention provides a method for constructing an artificial intelligence-based dynamic assessment model of multiple injuries in mice. This method includes:

[0054] In step S11, a controlled impact is applied to the mouse cranium to cause brain injury, and a controlled trauma is introduced in the chest and abdomen to simulate thoracic and abdominal cavity injuries.

[0055] In step S12, the physiological parameters of the injured mouse are monitored in real time by a sensing device, and physiological data reflecting the effects of brain and chest and abdomen injuries are collected. The physiological parameters include one or more of intracranial pressure, blood pressure and respiratory rate.

[0056] In step S13, the physiological data is input into an artificial intelligence algorithm model for time-series analysis and cross-system data fusion to assess the severity of injury in the injured mouse in real time and generate corresponding assessment results.

[0057] In step S14, the evaluation results are used to classify the severity of the injury, and a corresponding mouse model of multiple injuries to the brain and chest and abdomen is established accordingly.

[0058] In one embodiment, a closed-loop feedback control modeling platform for multiple injuries is established. The damage level is precisely controlled through mechanical feedback. Combined with multiple types of implantable physiological sensors and artificial intelligence algorithms, the multiple injury process is collected, analyzed, and graded in real time, providing a high-fidelity and highly universal experimental basis for mechanism research and intervention strategy verification.

[0059] This study aims to construct a mouse model of multiple injuries involving the cranium and chest / abdomen, achieving a closed-loop integration of injury-inducing manipulation and damage assessment. Starting with controlled impacts to the mouse cranium to induce brain injury, and introducing controlled trauma to the chest and abdomen to simulate thoracic and abdominal injuries, this approach differs from traditional single-site injury methods by simultaneously introducing controlled injuries at multiple sites on the same animal, thus more closely resembling clinical scenarios of multiple injuries. The use of controlled mechanical injury methods allows for precise damage energy management targeting the cranium and chest / abdomen, avoiding the randomness of injury outcomes caused by experimental conditions and individual animal differences, and improving the grading consistency and reproducibility of the experimental model.

[0060] The physiological parameters of the injured mice were monitored in real time using a sensing device, and physiological data reflecting the effects of intracranial and thoracic-abdominal injuries were collected. These physiological parameters included one or more of intracranial pressure, blood pressure, and respiratory rate, enabling multimodal and real-time acquisition of physiological signals. By implanting or attaching highly sensitive sensors into the mice, physiological data could be dynamically acquired throughout the entire process following injury induction. These physiological parameters not only reflected the initial effects of the injury but also allowed for real-time tracking of the body's adaptive response to combined injuries and the physiological cascade process.

[0061] The physiological data is input into an artificial intelligence algorithm model for time-series analysis and cross-system data fusion, enabling real-time assessment of the severity of injury in the injured mice and generating corresponding evaluation results. Through deep learning, feature extraction, and fusion of multimodal time-series physiological data, the model surpasses manual threshold interpretation, achieving automatic identification of injury severity, trend prediction, and early warning. Time-series analysis ensures the model's sensitivity to dynamic evolution processes, while cross-system data fusion enhances the understanding of pathological correlations and interactions among multiple organs.

[0062] The assessment results were used to grade the severity of injuries, and a corresponding mouse model of multiple injuries to the brain and chest / abdomen was established accordingly. The grading results generated by artificial intelligence can accurately distinguish the differences in the degree of injury, development trend, and prognostic risk among individuals with multiple injuries, forming a quantifiable and comparable multi-level injury model. This not only allows for model customization to meet different experimental needs but also realizes the objective grading of animal models, moving beyond subjective experience-based interpretation.

[0063] The system integrates a multi-chamber coupled injury module. In the reconstruction of craniocerebral injuries, an electromagnetically driven impactor is used, enabling real-time monitoring of intracranial pressure (ICP) via pressure sensors and dynamic adjustment of the impact force (range 0.5–2.5 J). This ensures a linear relationship between the degree of injury (mild, moderate, severe) and the input energy, solving the technical challenge of nonlinear correspondence between mechanical parameters and the actual degree of brain tissue damage in traditional gravity-based free-fall models. For chest and abdominal injuries, the system integrates a miniature hydraulic puncture needle. Based on real-time monitoring of blood pressure (BP) and blood lactate levels, it dynamically adjusts the liver and spleen puncture depth (0.1–1.0 mm) and blood loss rate (5–20 μL / min), accurately simulating the physiological process of uncontrollable hemorrhagic shock. This surpasses the limitations of previous fixed-parameter models in terms of dynamic controllability of injury and model realism.

[0064] In terms of modeling stress transmission and pathological mechanisms across chambers, the scheme introduces a miniature pressure wave generator implanted in the thoracic cavity, which can release controllable shock waves with frequencies of 10–50 Hz. Based on a finite element simulation model, the propagation path of stress between the cranium and the thoracic and abdominal cavities is pre-calculated. Through the principle of mechanical coupling, the cascade effect of secondary craniocerebral injury caused by thoracic injury can be quantified.

[0065] By performing a miniature CT scan on the mouse before surgery, three-dimensional anatomical atlases such as skull thickness, brain volume, and thoracic cavity structure can be obtained. Based on this, the impact position and angle can be dynamically adjusted with an adjustment accuracy of ±2°, significantly reducing the damage dispersion caused by anatomical differences.

[0066] Before model construction, a mini-CT scanner was used to perform a comprehensive scan of each mouse to obtain a three-dimensional anatomical atlas, including skull thickness, brain volume, and thoracic cavity structure. Based on the above individualized three-dimensional atlas, the researchers were able to dynamically adjust the impact position and angle at the time of injury, with an adjustment accuracy of ±2°, which significantly reduced the dispersion of injury distribution caused by individual anatomical variations in mice.

[0067] A dynamic monitoring system was constructed, and an implantable multimodal sensor array was used to collect key physiological parameters in mice in real time and at high frequency, covering 12 dimensions such as intracranial pressure, blood lactate, and respiratory rate. The sampling frequency reached 100Hz. The implantable multimodal sensor array is shown in Table 1 below.

[0068] Table 1

[0069]

[0070] The collected multimodal time-series data are processed by a dynamic adaptive artificial intelligence evaluation engine. Short-term memory networks (LSTM) are used to identify key time-window events such as short-term intracranial pressure spikes and blood lactate inflection points after injury. Graph neural networks (GNNs) further analyze the causal relationships between various systems, outputting a dynamic score for multiple injuries in real time. The stages of the dynamic model construction process are shown in Table 2 below.

[0071]

[0072] In cross-system interactive modeling, a multi-scale finite element simulation engine based on individual CT data was introduced to construct a three-dimensional finite element mesh of the cranium-thoracic abdomen, simulating the propagation of shock waves among cerebrospinal fluid, lung parenchyma, and abdominal organs, and calculating the distribution of local strain energy density (SED). Microdialysis technology was used to monitor brain tissue GFAP and serum Tau protein levels, establishing a quantitative relationship between SED and biochemical damage markers, achieving dual coupling modeling of biomechanics and biochemistry. Furthermore, optogenetic stimulation of the dorsal nucleus of the vagus nerve enabled controllable induction of autonomic dysfunction, simulating the multi-system pathological progression and cascade reactions after multiple injuries.

[0073] A federated learning and adaptive control platform was built, with a multi-center data lake architecture supporting local training of AI sub-models in different laboratories and improving model generalization ability through cloud parameter aggregation. A neurofunctional-behavioral quantitative description system was established through multimodal data standardization, and multiple methods such as gait analysis and cognitive assessment were used to comprehensively characterize animal models with multiple injuries. The system incorporates a dynamic adaptation algorithm that can automatically adjust injury parameters or implement simulated resuscitation operations based on MDSS scores and blood lactate levels, achieving closed-loop dynamic optimization throughout the entire process.

[0074] To verify the controllability of the injury, this technical solution designed a comparative experiment on the linear relationship of traumatic brain injury. Specifically, C57BL / 6 mice were used as experimental subjects (n=20 per group). Traumatic brain injury was induced using both a traditional gravity-induced fall model (grouped by the product of weight and fall height, gcf) and the electromagnetically driven impactor proposed in this solution (with real-time calibration combined with pressure feedback). The impact energy was set to increase in a gradient within the range of 1.0–2.0 J. A systematic evaluation of the relationship between tissue damage and input energy under the two injury methods was conducted, and the results are shown in Table 3 below.

[0075] Table 3

[0076]

[0077] To verify the dynamic simulation capability of thoracic and abdominal blood loss, a comparative experimental design was adopted. One group used traditional liver and spleen puncture with a fixed blood loss of 0.5 mL; the other group used the hydraulic puncture needle of this technology, dynamically adjusting the blood loss rate (5–20 μL / min) based on real-time monitoring of the blood pressure drop slope. The results showed that when predicting the irreversible shock point, the survival rate of the traditional model with blood lactate > 5 mmol / L as the cutoff was only 40% (with a false positive rate as high as 60%), while the survival rate of the dynamic blood loss group in this patented model increased to 85%, demonstrating that the real-time regulation mechanism can effectively avoid excessive blood loss.

[0078] To construct an efficient dynamic monitoring system, this technical solution employs a multimodal implantable sensor network to achieve high-precision, real-time monitoring of key physiological parameters in mice. The implantable sensors possess high sensitivity and accuracy, continuously capturing multidimensional physiological signals such as intracranial pressure, blood pressure, and respiratory rate. The accuracy of the implantable sensors is shown in Table 4 below.

[0079] Table 4

[0080]

[0081] For the grading and evaluation of multiple injuries, the proposed solution established a dynamic MDSS scoring model. The training dataset consisted of 120 mice from three laboratories (including five strains such as C57BL / 6 and BALB / c), while the test set consisted of 30 mice from an independent center. Through systematic training and independent validation using large-sample data from multiple centers, the model's performance across strains and experimental scenarios was comprehensively evaluated. The performance comparison is shown in Table 5 below.

[0082] Table 5

[0083]

[0084] The technical solution in this embodiment achieves controlled and highly reproducible grading of a mouse model of multiple injuries to the brain and chest / abdomen through controlled injury and real-time multimodal physiological monitoring. Combining artificial intelligence algorithms with dynamic evaluation of continuous physiological data accurately reflects changes in injury severity, enabling intelligent and standardized grading assessment. This solution overcomes the limitations of traditional models in terms of injury controllability, dynamic monitoring, and single evaluation methods, improving the model's physiological relevance and scientific rigor.

[0085] In one embodiment, such as Figure 2 As shown, step S11 includes the following steps S21-S22:

[0086] In step S21, a pressure sensor is implanted in the mouse's cranial cavity to monitor intracranial pressure in real time;

[0087] In step S22, the force of the impact device is adjusted according to the feedback of the intracranial pressure to achieve the predetermined degree of traumatic brain injury.

[0088] In one embodiment, a real-time feedback mechanism for injury controllability and physiological parameters was constructed during the establishment of a mouse model of traumatic brain injury. By implanting pressure sensors into the mouse cranial cavity, intracranial pressure can be dynamically and accurately monitored. Compared with traditional animal models that rely on mechanical parameters (such as weight, drop height, etc.) or endpoint behavioral evaluations, this mechanism can reflect the actual stress and degree of damage to brain tissue during injury in real time. The force of the impact device is adjusted based on the real-time monitoring results of intracranial pressure to achieve predetermined control over the degree of traumatic brain injury. The physiological-mechanical closed-loop regulation mechanism achieves dynamic matching between injury input parameters and physiological responses, overcoming the problem of nonlinear correlation between mechanical injury parameters and actual tissue damage. Through feedback adjustment, the degree of injury can be fine-tuned in real time during the experiment, improving the consistency of injury grading among multiple groups of animals.

[0089] In one embodiment, such as Figure 3 As shown, step S11 further includes the following steps S31-S32:

[0090] In step S31, a miniature hydraulic puncture needle is inserted into the thoracic or abdominal cavity of the mouse to puncture internal organs and induce bleeding;

[0091] In step S32, the bleeding rate is dynamically adjusted by a micro-flow pump linked to the puncture needle according to the mouse's blood pressure changes, thereby simulating an uncontrolled hemorrhagic shock process.

[0092] In one embodiment, a dynamic simulation of pathological changes in the thoracic and abdominal cavities in a multiple injury model was designed based on the construction process of thoracic and abdominal injuries in mice. By inserting a miniature hydraulic puncture needle into the thoracic or abdominal cavity of the mouse, precise mechanical damage and hemorrhage induction in specific organs (such as the liver and spleen) can be achieved. This is more controllable than traditional mechanical puncture or tissue cutting, and helps to standardize the extent and location of injury. The precise implementation of mechanical injury provides a stable foundation for the real-time acquisition and dynamic control of subsequent physiological parameters. Based on the design of a feedback closed loop that dynamically adjusts the bleeding rate according to blood pressure changes, the bleeding rate can be finely adjusted in real time according to the blood pressure level monitored by the mouse, thereby accurately simulating the complex pathological process of uncontrollable hemorrhagic shock in clinical practice. This mechanism effectively overcomes the problems of fixed blood loss, simple shock process, and lack of dynamic regulation in previous animal models, and achieves a high degree of coupling between injury and physiological response.

[0093] In one embodiment, such as Figure 4 As shown, step S12 includes the following steps S41-S44:

[0094] In step S41, an optical fiber intracranial pressure sensor is implanted into the cranial cavity of the mouse to monitor changes in intracranial pressure.

[0095] In step S42, a flexible strain sensor is implanted in the thoracic cavity or chest wall of the mouse to monitor respiratory rate and determine the status of hemopneumothorax.

[0096] In step S43, a miniature ultrasound probe is implanted into the peritoneal cavity of the mouse to monitor the amount of bleeding in the peritoneal cavity;

[0097] In step S44, a microneedle-type blood lactate sensor is implanted in the mouse to monitor systemic metabolic disorders.

[0098] In one embodiment, multiple types of implantable physiological sensors were introduced during the construction of a mouse model of multiple brain injuries, enabling real-time, multi-dimensional monitoring of key physiological parameters. By implanting fiber optic intracranial pressure sensors into the mouse cranial cavity, intracranial pressure changes can be continuously and dynamically acquired, providing objective data for assessing the degree of brain injury and subsequent regulation. Compared with traditional methods relying on endpoint behavioral or single-point pathological analysis, this approach enhances the sensitivity to the development of traumatic brain injury and helps capture real-time signals of key pathological stages such as cerebral edema and secondary brain injury.

[0099] Flexible strain sensors in the thoracic cavity or chest wall are used to monitor respiratory rate in real time and can assist in the assessment of important thoracic pathological conditions such as hemopneumothorax. Miniature ultrasound probes deployed in the abdominal cavity can non-invasively and dynamically monitor changes in intra-abdominal hemorrhage, providing high-resolution quantitative data for assessing abdominal organ damage and blood loss. Microneedle-type blood lactate sensors can reflect the body's systemic metabolic level and oxygenation status in real time, serving as an important indicator for monitoring the progression of multiple traumatic shock. The introduction of these highly integrated, multimodal sensing methods enriches the dimensions and depth of model data. It overcomes the limitations of previous single or intermittent monitoring techniques, achieving full-process, closed-loop acquisition of physiological information from multiple systems. Through these sensor networks, the complex responses and cascading changes of various tissues and organs after mouse injury can be captured in a timely manner.

[0100] In one embodiment, such as Figure 5 As shown, it also includes the following steps S51-S53:

[0101] In step S51, the intracranial pressure, respiratory rate, bleeding volume, and blood lactate collected by the sensor are input into the artificial intelligence model as multimodal time-series data;

[0102] In step S52, the time-series data is analyzed using a recurrent neural network to identify the correlation between key events and different physiological parameters during the injury process;

[0103] In step S53, the severity score of multiple injuries and / or early warning signals are output in real time.

[0104] In one embodiment, the construction and evaluation process of animal models of multiple injuries integrates an intelligent processing and analysis mechanism for multimodal time-series data, demonstrating data-driven scientific grading and early warning capabilities. By inputting multiple key physiological parameters such as intracranial pressure, respiratory rate, hemorrhage volume, and blood lactate collected by sensors into the artificial intelligence model in the form of time-series data, a solid foundation is laid for continuous monitoring and dynamic analysis of the entire process of multiple injuries. Unlike traditional evaluation models that rely solely on single or endpoint data, this approach achieves full-dimensional information capture of the entire process of injury occurrence, development, and recovery, ensuring the real-time nature of model evaluation.

[0105] At the data processing level, deep learning methods such as recurrent neural networks (RNNs) were introduced to analyze multimodal time-series data. RNNs excel at processing time-series information, automatically uncovering potential connections and patterns of change among various physiological parameters at different time points, enabling dynamic identification of key events in the injury process (such as brain herniation, circulatory imbalance, and metabolic deterioration). RNNs possess memory and recursive capabilities, allowing them to integrate historical information from multiple parameters and analyze the interactions between different systems (such as the nervous, circulatory, and metabolic systems), thereby revealing the systemic pathological coupling mechanisms under complex multiple injury models. The system outputs real-time scores and / or early warning signals based on the severity of multiple injuries, achieving intelligent and standardized dynamic hierarchical management. The scoring system automatically adjusts the model's grading standards based on changes in physiological parameters, promptly reflecting individual differences in injury and progression trends. The early warning mechanism issues signals before critical changes in injury, organically combining multimodal physiological data, deep learning algorithms, and an intelligent scoring system to establish a closed-loop platform spanning the entire process of injury, monitoring, assessment, and early warning.

[0106] In one embodiment, such as Figure 6 As shown, it also includes the following steps S61-S63:

[0107] In step S61, a miniature CT scan is performed on the mouse before injury to obtain an individual anatomical atlas of the mouse, including skull thickness, brain volume and thoracic cavity structure.

[0108] In step S62, the impact position and angle of the traumatic brain injury are adjusted based on the anatomical atlas to reduce the injury dispersion caused by individual differences.

[0109] In step S63, the propagation path of mechanical stress in the thoracic cavity to the brain is simulated by a finite element model, and the parameters of the chest and abdominal injury are calibrated accordingly to achieve the predetermined degree of secondary brain injury.

[0110] In one embodiment, an integrated mechanism of individualized anatomical information and biomechanical simulation was introduced into the construction process of a mouse multiple injury model to further improve the accuracy of model grading and the reproducibility of experimental results. By performing miniature CT scans on mice before injury, detailed anatomical data such as individual skull thickness, brain volume, and thoracic cavity structure were obtained, effectively solving the problem of high dispersion in injury manifestations caused by large individual anatomical differences in traditional models.

[0111] With the support of anatomical atlases, the impact location and angle of craniocerebral injury are adjusted based on individual anatomical characteristics. Precise matching not only significantly reduces injury deviations caused by differences in anatomical structures between different experimental animals, but also provides strong support for graded modeling and reproducible experiments. The propagation path of intrathoracic mechanical stress to the cranium is simulated using a finite element model, and relevant parameters of thoracic and abdominal injuries are calibrated accordingly to achieve precise control over the predetermined degree of secondary craniocerebral injury. Finite element simulation can reveal the propagation and energy distribution patterns of stress waves under different anatomical structures and stress conditions, thus providing theoretical support for the mechanical control and parameter setting of multiple injury models. The closed-loop process of physical simulation-physiological feedback-parameter calibration enables multiple injury models to possess a high degree of refinement and controllability in damage control, cross-compartmental coupling, and mechanism research.

[0115] The analysis module 73 is used to input the physiological data into an artificial intelligence algorithm model, perform time-series analysis and cross-system data fusion, assess the severity of the injury in the injured mouse in real time, and generate corresponding assessment results.
