Fig. 1 is a flowchart of a user safety protection method according to an embodiment of the present invention, which can be applied to a situation where a patient with anxiety disorder with a risk tendency is to be protected, and the method can be performed by a user safety protection device according to an embodiment of the present invention, which can be implemented in software and/or hardware, and can be generally integrated into an apparatus for providing safety protection for a patient with anxiety. As shown in fig. 1, the method of this embodiment specifically includes:
s110, obtaining the resting state data of the monitoring user in real time through the wearable device.
The rest state is the non-task state of the brain, and specifically, the state requires the tested person to be in a clear and quiet state, close eyes and breathe calmly, reduces the movement of the head as much as possible, and does not need any thinking activity. The brain function data acquired in the resting state is referred to as resting state data.
The wearable device may be a head-supported wearable device such as a headband, for example, and is used to acquire resting brain function data of the head of the monitored user. For a patient who is in an anxiety state for a long time and has a dangerous tendency (for example, a suicide tendency), the wearing device should be worn all the time without being attended to.
In an optional implementation manner of this embodiment, a resting state nuclear magnetic resonance image of the head of the monitoring user may be acquired by the wearable device, and data acquisition is performed on the acquired resting state nuclear magnetic resonance image to obtain resting state data of the monitoring user.
And S120, if the monitoring user is determined to be in an anxiety state according to the resting state data of the monitoring user, acquiring security inspection parameters of the monitoring user.
When the monitoring user is determined to be in the anxiety state, the safety inspection can be performed on the behavior of the monitoring user, namely the safety inspection parameters of the monitoring user are obtained. Specifically, the motion trajectory data of the monitoring user and/or the motion characteristic parameters of the monitoring user may be used as the safety inspection parameters, for example, whether the user keeps constant hand and foot motions (such as grabbing hair, touching ears, rubbing faces, holding chest with both hands, twisting and pressing both hands with force, tapping, and the like) or whether the user is walking back and forth quickly or slowly with head lowered (such as a walking route is a circle) may be monitored; the geographical location information of the monitoring user and/or the height information of the monitoring user may also be used as the security check parameter, for example, whether the monitoring user is located at an outdoor high dangerous location such as a roof, or whether the monitoring user is located at a dangerous place such as a river or a bridge. Wherein, the place which is closer to the water area and/or has higher altitude can be regarded as the dangerous area.
In an optional implementation manner of this embodiment, the functional coupling strength between the nucleus pulposus region of the monitoring user and at least one first selected brain region around the nucleus pulposus region of the monitoring user can be calculated according to the resting state data; if the functional coupling strength is determined to meet the first anxiety condition, acquiring local field potential LFP signals of at least one target brain area of the monitoring user; determining that the monitored user is in an anxiety state if the theta rhythm of the LFP signal for the target brain region is determined to satisfy a second anxiety condition.
And S130, if the safety inspection parameters are determined to meet the danger early warning conditions, setting a safety protection strategy to perform safety protection on the monitoring user.
The method includes judging whether security inspection parameters of a monitoring user meet a danger early warning condition or not, if so, performing security protection on the monitoring user by adopting a set security protection strategy, for example, sending first danger early warning information to at least one preset associated user (such as guardians of parents, couples, children and the like) terminal (such as a mobile terminal of a mobile phone and the like) corresponding to the monitoring user, namely informing the associated user that the monitoring user is in an anxiety state and has a danger tendency, and simultaneously notifying the associated terminal of geographical location information of the monitoring user so that the corresponding associated user can arrive at the location of the monitoring user as soon as possible to pacify the monitoring user.
The second danger early warning information may also be sent to other user terminals in the surrounding environment of the monitoring user, for example, in the form of voice, through a nearby mobile base station, to terminals of other surrounding users (for example, mobile terminals such as mobile phones) to seek help, and notify other surrounding users that the monitoring user is in an anxiety state and has a danger tendency, so that the other surrounding users of the monitoring user perform security monitoring on the monitoring user, and the monitoring user is prevented from making an over-excited behavior.
In an optional implementation manner of this embodiment, when the motion trajectory data of the monitoring user and/or the motion characteristic parameters of the monitoring user are used as the safety inspection parameters, it may be determined that the safety inspection satisfies the danger early warning condition when the monitoring user has abnormal behaviors such as continuous hand and foot motions (e.g., catching hair, touching ears, rubbing faces, holding breasts with both hands, twisting and pressing both hands with strength, tapping, etc.), fast walking back and forth, or slow walking with low head (e.g., the walking route is a circle).
In another optional implementation manner of this embodiment, when the geographical location information of the monitoring user and/or the height information of the geographical location where the monitoring user is located are/is used as the security check parameter, it may be determined that the security check satisfies the security early warning condition, for example, that the monitoring user is located in a dangerous area (for example, a dangerous location such as an outdoor dangerous location such as a roof, a dangerous place such as a river side or a bridge) that is relatively close to the water area and/or has a relatively high altitude.
According to the safety protection method for the user, the resting state data of the monitored user are obtained in real time through the wearable device; if the monitoring user is determined to be in an anxiety state according to the resting state data of the monitoring user, security inspection parameters of the monitoring user are obtained; if the safety inspection parameters meet the danger early warning conditions, a technical means of setting a safety protection strategy to carry out safety protection on the monitoring user is adopted, so that the safety protection strategy is adopted for the monitoring user when the monitoring user is in an anxiety state and has a danger tendency, and the occurrence of unfortunate events caused by the overstimulation behavior of the monitoring user can be avoided as much as possible.
Example two
Fig. 2A is a flowchart of a user security protection method according to a second embodiment of the present invention, which is embodied on the basis of the second embodiment, in this embodiment, the obtaining, in real time, resting state data of a monitoring user through a wearable device specifically includes: acquiring a resting-state nuclear magnetic resonance image of the head of the monitoring user through the wearable device; and carrying out data acquisition on the obtained resting-state nuclear magnetic resonance image to obtain resting-state data of the monitoring user.
And determining that the monitoring user is in an anxiety state according to the resting state data of the monitoring user, specifically: calculating the functional coupling strength between the nucleus accumbens brain area of the monitoring user and at least one first selected brain area around the nucleus accumbens brain area according to the resting state data; acquiring a local field potential, LFP, signal of at least one target brain region of the monitoring user if it is determined that the functional coupling strength satisfies a first anxiety condition; determining that the monitoring user is in an anxiety state if the theta rhythm of the LFP signal of the target brain region is determined to satisfy a second anxiety condition.
Correspondingly, the method of the embodiment may include:
s210, obtaining the resting nuclear magnetic resonance image of the head of the monitoring user through the wearable device.
The wearable device can realize functional magnetic resonance imaging, and the principle is that the magnetic resonance imaging is used for measuring the change of blood power caused by neuron activity.
S220, carrying out data acquisition on the obtained resting-state nuclear magnetic resonance image to obtain resting-state data of the monitoring user.
During magnetic resonance scanning, the magnetic resonance scanner and the head movement, breathing and the like of the user to be detected can affect the acquired data, and in order to detect and repair the artifacts and the noise, some necessary preprocessing is needed before the data is formally analyzed. Firstly, removing data of the first time points influenced by factors such as magnetic field nonuniformity and the like when scanning is started; and then, taking the result of the later time point data after head-motion correction, space standardization, space smoothing, filtering and physiological noise removal as the resting state data of the user to be detected for analysis.
And S230, calculating the functional coupling strength between the nucleus pulposus area of the monitoring user and at least one first selected brain area around the nucleus pulposus area of the monitoring user according to the resting state data.
The inventor finds out through repeated experiments that: the nucleus accumbens brain area is a brain area closely related to anxiety emotion regulation, and clinical nuclear magnetic resonance results show that the activity of the nucleus accumbens brain area is different from that of normal people in anxiety patients, and the functional linkage strength of the nucleus accumbens brain area and other main brain areas around the nucleus accumbens brain area is also different from that of the normal people. The strength of functional links between brain regions reflects the ability of the brain to coordinate with each other.
Therefore, in this embodiment, first, the anxiety state of the user to be tested is preliminarily determined according to the functional coupling strength between the nucleus accumbens brain region and the surrounding selected brain region of the user to be tested.
The brain areas around the nucleus accumbens brain area are mainly: the frontal cortex of the right lateral frame, ventral prefrontal cortex, bilateral temporal cortex, amygdala, caudate nucleus, anterior cingulate gyrus, hippocampus, right inferior parietal lobe, islet lobe, posterior parietal cortex, prefrontal cortex, cingulate cortex, etc.
Accordingly, a person skilled in the art can select a suitable first set brain region according to the actual experimental effect and the implementation difficulty, which is not limited in this embodiment.
In an alternative embodiment of this embodiment, the first selected brain region may be the hippocampus. Namely, the functional coupling strength between the nucleus accumbens brain area and the hippocampus brain area of the user to be tested can be calculated according to the acquired resting state data.
Optionally, the voxel signals in the nucleus accumbens brain area and the hippocampus brain area may be determined according to the resting state data of the user to be tested. And respectively carrying out averaging processing on each voxel signal corresponding to the nucleus accumbens brain area and the hippocampal brain area to obtain a result which is used as a resting state signal of the nucleus accumbens brain area and the hippocampal brain area, and finally calculating a correlation coefficient between the two resting state signals to be used as the functional coupling strength between the nucleus accumbens brain area and the hippocampal brain area of the user to be detected.
And S240, judging whether the function connection strength meets a first anxiety condition, if so, executing S250, and if not, executing S2120.
First, it is determined whether the calculated functional linkage strength between brain regions satisfies a first anxiety condition.
Wherein, the inventor obtains through experimental analysis: in transgenic mice with a deleted anxious mood gene, the functional linkage strength between the nucleus accumbens brain region and other major brain regions of the brain (such as hippocampal brain region, etc.) is significantly lower than that of wild-type mice (i.e., mice in an anxious state).
Thus, if the functional bond strengths of the nucleus accumbens brain region and each of the first selected brain regions are each greater than the corresponding standard functional bond strength, it may be determined that the functional bond strength satisfies the first anxiety condition; if the functional linkage strength of the nucleus accumbens brain region and a plurality of first selected brain regions with a set number are respectively greater than the corresponding standard functional linkage strength, the functional linkage strength can also be determined to meet the first anxiety condition.
For example: the number of the first selected brain areas is 4, namely a brain area A, a brain area B, a brain area C and a brain area D; the standard functional link strength corresponding to brain region a is a1, the standard functional link strength corresponding to brain region B is B1, the standard functional link strength corresponding to brain region C is C1, and the standard functional link strength corresponding to brain region D is D1.
Accordingly, it may be predefined that, if the calculated functional bond strengths of the nucleus accumbens brain region and the 4 first selected brain regions are respectively greater than the standard functional bond strength corresponding to each first selected brain region, it is determined that the functional bond strength satisfies the first anxiety condition; and if the functional joint strength of a set number (for example, 2 or 3) of the calculated functional joint strengths of the nucleus accumbens brain region and the 4 first selected brain regions is respectively greater than the standard functional joint strength corresponding to each first selected brain region, determining that the functional joint strength meets the first anxiety condition.
Wherein the functional bond strength between the nucleus accumbens region and at least a first selected brain region surrounding the nucleus accumbens region, which is derived by analyzing resting state data of a plurality of users in a calm state, which are not in an anxiety state, is referred to as a standard functional bond strength.
Typically, the average value of the functional coupling strengths between the nucleus accumbens brain region and at least one first selected brain region around the nucleus accumbens brain region may be calculated according to the resting state data of the user in a plurality of resting states and not in an anxiety state, and the average value is used as a uniform standard functional coupling strength; the calculated functional bond strength between the nucleus accumbens brain region and a certain first selected brain region may also be used as the standard functional bond strength corresponding to the first selected brain region.
Optionally, the standard functional link strengths of the nucleus accumbens brain region and the different first selected brain regions are different, i.e., different standard functional link strengths are determined separately for the different first selected brain regions.
And S250, taking a local field potential LFP signal of at least one target brain area of the monitoring user.
In this embodiment, the target brain region is the nucleus accumbens brain region. Brain waves are electrical potential differences formed between cerebral cortex cell populations when a computer is active, thereby generating an electrical current outside the cerebral cortex cells. They are the general reaction of the electrophysiological activity of the brain nerve cells on the surface of the cerebral cortex or scalp, and the changes of the electric waves during brain activity are recorded to obtain an electroencephalogram. Acquiring a signal corresponding to a target brain area in electroencephalogram data as an LFP signal of the target brain area, wherein a local potential LPF signal reflects an activity state of a local nerve nucleus from a neural network and is a cooperative behavior of a neural set. The LFP signal of a target brain region is a complex response of the sum of the numerous neuronal dendritic potentials within the target brain region.
And after determining that the functional coupling strength meets a first anxiety condition, acquiring an LFP signal of at least one target brain area of the user to be detected. The LFP signals comprise theta-band (4-7 Hz) signals and gamma-band (31-50Hz) signals.
The target brain region may be the nucleus accumbens brain region, and at least one second selected brain region around the nucleus accumbens brain region. The second selected brain region may be one of right lateral rim frontal cortex, ventral lateral prefrontal cortex, bilateral temporal cortex, amygdala, caudate nucleus, anterior cingulate gyrus, hippocampus, right inferior parietal lobe, insular lobe, posterior parietal cortex, prefrontal cortex, cingulate cortex, and the like.
Among them, the inventor finds out through multiple tests that: the theta band signal in the LFP signal will change according to whether the user is anxious, and the gamma band signal will not change according to whether the user is anxious.
Accordingly, in this embodiment, the anxiety state of the user to be tested is further determined according to the characteristics of the theta rhythm of the LFP signal in the target brain region of the user to be tested. By the combination of the preliminary judgment based on the functional link strength between the nucleus accumbens brain area of the user to be tested and the selected brain area around the nucleus accumbens brain area and the further judgment based on the theta rhythm characteristic of the LFP signal of the target brain area, an anxiety state judgment result with high accuracy can be obtained.
And S260, judging whether the theta rhythm of the LFP signal of the target brain area meets a second anxiety condition, if so, executing 270, and if not, executing S2120.
And judging whether the theta rhythm of the LFP signal of the target brain region meets a second anxiety condition. First, the theta rhythm intensity parameter of the target brain region may be obtained according to the theta rhythm of the LFP signal of the target brain region, for example, the theta rhythm intensity parameter may be an average signal power corresponding to the theta rhythm, a maximum signal power corresponding to the theta rhythm, or a signal energy corresponding to the theta rhythm.
The inventor finds out through multiple researches that: rodents exhibit natural avoidance of the open arm in the elevated plus maze test and may represent an anxiety state in the animal. As shown in FIG. 2B, the intensity (power) of the theta rhythm at the frequency of 4-7 Hz in the open arm (open arms) environment is significantly less than that of the theta rhythm in the closed arm (closed arms) environment. That is, the mice enter an open arm exhibiting an anxious emotional state, at which time LFP recordings of the nucleus accumbens region show a decrease in the intensity of the band theta, whereas in a relatively safe closed arm environment, the mice exhibit relatively low anxiety, at which the intensity of theta is also higher than the level of the open arm.
As shown in fig. 2C, by monitoring the brain wave of gamma band, it was found that the intensity of gamma rhythm did not significantly change regardless of whether the mouse was in an open arm environment or a closed arm environment. That is, gamma rhythm in the nucleus accumbens brain region is independent of anxiety states.
In a transgenic animal model with a loss of normal anxiety mood expression, the theta rhythm in the nucleus accumbens region does not show the change expected from the wild type (in an anxious state) in the presence of anxiety in the animal. It follows that the theta rhythm in the nucleus accumbens brain region is associated with an anxiety state.
Thus, if the theta rhythm intensity parameter of each target brain region is less than the corresponding standard theta rhythm intensity parameter, it may be determined that the second anxiety condition is satisfied; it may also be determined that the second anxiety condition is satisfied if a set number of the plurality of target brain regions have a theta rhythm intensity parameter less than a corresponding standard theta rhythm intensity parameter. When the theta rhythm of the LFP signal of the target brain region meets a second anxiety condition, the user to be tested can be determined to be in an anxiety state.
Wherein the standard theta rhythm intensity parameter is determined by analyzing the theta rhythm of the LFP signal for a target brain region of the user in a plurality of calm states.
Typically, the theta rhythm of the LFP signal of the local field potential of the target brain region in the sample data is obtained by using the resting state data of the user in a plurality of resting states and not in an anxiety state as sample data, and the processed result may be used as the standard theta rhythm intensity parameter by performing mean analysis on the theta rhythm of the LFP signal of the target brain region in the sample data.
Specifically, the standard theta rhythm intensity parameters corresponding to different target brain regions are different.
In another optional implementation manner of this embodiment, determining whether the theta rhythm of the LFP signal in the target brain region of the user to be tested satisfies the second anxiety condition may further include: performing data sampling on the theta rhythm of the LFP signal of the target brain area (for example, nucleus accumbens brain area) of the user to be tested, acquiring a set number (for example, 100 or 200 or the like) of sampling points as a first sampling set, and performing one-to-one comparison between the sampling points and a standard sampling set (wherein, the standard sampling set is determined by analyzing the theta rhythm of the LFP signal of the target brain area of the user in a plurality of calm states), and if the numerical values of the sampling points exceeding a set percentage (for example, 80% or 90% or the like) in the first sampling set are all smaller than the sampling points in the standard sampling set, determining that the theta rhythm of the LFP signal of the target brain area of the user to be tested meets a second anxiety condition.
And S270, determining that the monitoring user is in an anxiety state.
S280, acquiring the motion trail data of the monitoring user and/or the motion characteristic parameters of the monitoring user.
For example, the intelligent wearable device may be used to obtain the hand and foot motion frequency and motion trajectory of the monitoring user to determine whether the monitoring user has continuous hand and foot motion (such as catching hair, touching ears, rubbing face, holding chest with both hands, twisting and beating with both hands, etc.), or the intelligent wearable device may be used to obtain the motion trajectory data of the monitoring user to determine whether the monitoring user is walking back and forth quickly or walking slowly with a motion trajectory similar to a circle.
And S290, judging whether the monitoring user is in an abnormal behavior state or not according to the motion track data and/or the motion characteristic parameters, if so, executing S2100 and/or S2110, and if not, executing S290.
If the action frequency of the hands and the feet of the monitoring user is high and the actions of the hands and the feet are continuous (such as hair grabbing, ear touching, face rubbing, chest holding by two hands, twisting and pressing by two hands, beating and the like), the behavior state of the monitoring user can be determined to be abnormal; if the monitoring user walks back and forth quickly or slowly with a circle-like motion track for a long time, the behavior state of the monitoring user can be considered to be abnormal.
S2100, sending first danger early warning information to at least one associated user terminal corresponding to the monitoring user, and notifying the associated terminal of geographical position information of the monitoring user.
And S2110, sending second danger early warning information to other user terminals in the surrounding environment of the monitoring user, so that the other users around the monitoring user can perform safety monitoring on the monitoring user.
When the monitoring user is judged to be in the abnormal behavior state, first danger early warning information can be sent to at least one preset associated user (such as parents, couples, guardians such as children) terminal (for example, a mobile terminal such as a mobile phone) corresponding to the monitoring user, namely the associated user is informed that the monitoring user is in an anxiety state and has danger tendency to require family members to take care of, and geographical location information of the monitoring user is reported to the associated terminal, so that the corresponding associated user can arrive at the location of the monitoring user as soon as possible to take care of the monitoring user.
Second danger early warning information can be sent to other user terminals in the surrounding environment of the monitoring user, for example, the second danger early warning information can be sent to terminals of other users (for example, mobile terminals such as mobile phones and the like) around the monitoring user in a voice form to seek help, and the monitoring user is informed to other users around the monitoring user that the monitoring user is in an anxiety state and has a danger tendency, so that the other users around the monitoring user can perform safety monitoring on the monitoring user, and the monitoring user is prevented from making an over-excited behavior; or the warning ring can be sent to the terminals of other surrounding users through the nearby mobile base station to remind the user to pay attention to the surrounding abnormal conditions.
Preferably, the two kinds of danger early warning messages can be transmitted simultaneously, so as to avoid the occurrence of unfortunate events caused by monitoring the overstimulation of the user to the maximum extent.
And S2120, determining that the monitoring user is not in an anxiety state.
According to the technical scheme of the embodiment, the monitored resting state data is obtained; calculating the functional coupling strength between the nucleus accumbens brain area of the monitoring user and at least one first selected brain area around the nucleus accumbens brain area according to the resting state data; if the functional coupling strength is determined to meet a first anxiety condition, acquiring Local Field Potential (LFP) signals of at least one target brain region of the monitoring user; technical means for determining that the monitored user is in an anxiety state if the theta rhythm of the LFP signal of the target brain region is determined to satisfy a second anxiety condition provides a method for objectively evaluating the anxiety state of the monitored user. And when judging that the monitoring user is in an anxiety state and has a danger tendency, sending danger early warning information to terminals which are pre-associated with the user and/or other surrounding users so as to realize mood appeasing and/or safety monitoring on the monitoring user and avoid unfortunate events caused by the overstimulation behavior of the monitoring user to the maximum extent.
