Sum of the deviations=α ∑ | BG (0)-BGt (0) |+β ∑ | PI (0)-PIt (0) |
+α∑|BG(1)-BGt(1)|+β∑|PI(1)-PIt(1)|
+α∑|BG(2)-BGt(2)|+β∑|PI(2)-PIt(2)|
+···
＝α{∑|BG(t)-BGt(t)|}+β{∑|PI(t)-PIt(t)|}

Users such as doctor can judge whether that by the numerical value (approximate response message) of actual inspection result (biological response information) in the contrast display graphics 131 and simulation reconstruction two values are approximate, whether the simulation living model has imitated the biologic-organ of actual patient really.According to the display graphics 131 of Figure 18, the actual inspection result is with present worth is very approximate again, so it is suitable to confirm to simulate the living model of generation.
[pathological characters obtains part]
System SS obtains the pathological characters information (the pathological characters information of system SS is obtained function) that shows patient's pathological characters according to the living model that generates (parameter group).
As shown in figure 18, in the present embodiment, adopt blood sugar 132a, basal secretion 132b on an empty stomach, append secretion 132c, secretion sensitivity 132d, glycogen newbornly suppress 132e, sugared processing power 132f, handle the index of sensitivity 132g as pathological characters.
These indexs are considered to fully to show pathological characters, particularly the biological function that can improve by treatment.
At this, blood sugar 132a is obtained by variable blood glucose value BG (t=0) calculating of living model on an empty stomach; Basal secretion 132b is by the variable of living model insulin I on an empty stomach
1(t=0) obtain; Append secretion by I
1(t=) integrated value is tried to achieve; Secretion sensitivity 132d is tried to achieve the susceptibility β that glucose stimulates by the parameter of living model; The newborn inhibition of glycogen 132e is obtained by the variable glycogen release HGTP (t) of living model; Sugar processing power 132f is calculated by the clean glucose SGO (t) and the blood glucose value BG (t) of the variable liver of living model; Processing sensitivity 132g is obtained by the parameter-per unit insulin and the insulin-dependent glucose consumption speed Kp of per unit glucose in the tip tissue of living model.
As mentioned above, because living model is by the mathematical model formation of the parameter (containing variable) with performance biologic-organ feature, so the demonstration of the parameter value of living model is the value relevant with pathology.Therefore, can calculate the pathological characters information of reflection pathological characters according to these parameters.
At the radar chart 132 of Figure 18, each pathological characters information refers to that target value draws circle and show, directly the quality of different each desired value of comparative unit and numerical value amplitude.
From the radar chart 132 of Figure 18 as can be seen, about the sugared processing power 132f of sugared processing power in the tip tissue with to handle sensitivity 132g lower.Therefore, the doctor who has seen radar chart (output of pathological characters information) can judge at an easy rate that the treatment policy of the sugared processing power of improving in the tip tissue is effective.
In addition, actual OGTT check result 131a, 131b and pathological characters information 132 are presented on the same picture, and the doctor can be by comparing the two, the graphics shape of study OGTT check result and the correlativity of pathology.Therefore use the SS of this system to accumulate experience by reality, can expectation obtain effective results of learning of holding pathology from the OGTT check result.
And the input picture of OGTT check result (biological response) can be imported any number of non-actual inspection result (biological response information), and obtains about the output of present worth (approximate response message) and pathological characters information again of the check result of this arbitrary value.Therefore, the doctor can try to import any check result value (biological response information) and understands in this case which kind of pathology can take place.So, also can import suitable check result even without the data of actual patient, which type of output result observation can obtain.
That is to say that native system SS also can be used as the usefulness of gp and doctor's learning training of lacking experience.
In addition, the pathological analysis by Figure 18 is set is display part 130 as a result, is convenient to user such as doctor and holds patient's pathology, learns the correlativity of check result and pathology simultaneously effectively.Because of showing actual inspection result and present worth again, can judge the correctness of shown pathological characters information and prevent to miss study again.
In pathological analysis display part 130 as a result, after the pathological analysis processing finishes, can show pathology explanation square cards for learning characters in pathology explanation display part 133.The pathology comment is logged in database S4 in advance, is selected and the corresponding pathology comment of the living model that generates (parameter) by system, and the literal of selection is presented at pathology explanation display part 133.In addition, clicking " showing detailed pathology " key 134 will show in more detail expressly at another window.
By demonstration pathology explanatory note like this, the pathological characters information that is presented on the radar chart 132 is easier to understand, and the doctor can hold pathology more accurately.
As mentioned above, after the doctor held pathology, decision treatment policy, decision prescription content, native system SS can login this prescription content.That is, click " login of prescription content " key 101b, Figure 19 " login of prescription content " picture W2 then occurs.The doctor can import medicine name etc. on this picture W2.After the input prescription content, click the login button W2R of picture W2, the content of then writing out a prescription signs in to database S4.
The picture of the Web browser C1 of Figure 20 after showing login prescription content after the pathological analysis result.
[pathological characters importation and approximate replying are obtained part]
Figure 21 shows the information processing of input pathological characters in display part 130 as a result at pathological analysis.The value of each index 132a～132g of radar chart display part 132 can be by the change of operation mouse.That is, can on radar chart display part 132, import pathological characters information.At Figure 21, sugared processing power 132f and the desired value of handling sensitivity 132g are changed by mouse action, and its result has obtained among the pathological characters information radar chart C1 that system SS generates sugared processing power 132f and handled the improved new radar chart C2 of sensitivity 132g.
In case each desired value of radar chart change, above-mentioned approximate replying obtained part (living model calculation part) and will be calculated the present worth again of blood glucose value and insulin, thereby demonstrates reproduction value 131e, the 131f of pathology after changing.
That is, after the input pathological characters information, system SS can change the living model parameter at the corresponding pathological characters information of importing, and generates new living model.And approximate replying obtained part (living model calculation part) meeting according to the living model of being imported with living model parameter reflection pathological characters, obtain the reproduction value 131e that replys as approximate, 131f.
So, system SS has pathological characters information input function, according to the OGTT reproduction value output function of pathological characters information acquisition of input, therefore, when intending improving the present state of an illness by treatment, can confirm to expect which kind of OGTT check result in advance.Therefore, the doctor can predict curative effect easily.Can also confirm to improve the curative effect which pathological index can obtain by the multiple pathological characters information of conversion, play a role determining correct treatment policy.
In the present embodiment, pathological characters information is to import by the operation on radar chart, but is not limited to this input method, also can be undertaken by the numerical value input.
[the different example of pathological characters information output]
