Background technology
The detection of inferior health and assessment are that health control finally provides the intervention means of individuation and requisite condition precedent.But at present all do not pass through the applied research and the implementation data support of scientific system because most inferior healths of being done to get up by market " stir-frys " detect with assessing " product ", thus only be short-lived just without a trace.[see for details: Wu Liuxin etc. the detection of inferior health and assessment, inferior health, Beijing: Chinese traditional Chinese medical science publishing house, 2007.79-126]
Some existing commercialization inferior healths detect the evaluation measures classification:
1. test the damage-free type assessment models that back diagnosis case is concluded based on both depositing disease
Although the mechanism of the damage-free type detection means of this type of inferior health detection evaluation measures is different, as can being channels and collaterals metrical information (as surface skin resistance), quantum and thermal imaging measured value etc., be not perspective health risk assessment on the strict disease early warning meaning but study carefully its assessment models of setting up by the information of being obtained through cave place; Because its modelling mechanism is to conclude the existing retrospective prompting (although this type of specious commercial propaganda that detects evaluating system claims it that disease is had early stage suggesting effect) that has produced disease attribute by detecting data in fact.The logic vagueness of setting up the methodology of this type of assessment models is that detection information is taken at and has the non-sub-health population of both depositing disease, the reality that adopts data processing to conclude then to draw had been for both having deposited the sign of disease attribute, and confused in the detection information criterion of the perspective health risk assessment on the disease early warning meaning under the sub-health state.
For solving above drawback, be necessary to adopt following based on inferior health--under the strictness prediction forecast meaning of-disease time series trend statistical study wound type epidemiology assessment models arranged.
2. based on inferior health---disease time series trend Statistic analysis models wound type epidemiology assessment models arranged
Any chronic disease all has its distinctive physiology and pathological change.Although these variations are complicated, very little variation all can embody on biomarker to some extent.The biomarker group does not here just consider the measured value of each single index, but comprise that numerous meaningful biological medical science indexs and other index that complete observation arrives reach to survey and interview etc., be total evaluation basically to people's physical condition; Therefore, if before disease takes place, record its biomarker pattern, and observe in the disease progression process situation of change of biomarker under the time series trend continuously, adopt the epidemiology statistics analytical approach, as Cox proportional hazard model [Cox DR.Regression models and life tables.J.R Stat Soc B, 1972,34:226-230] etc. set up assessment models and just can find to cause disease to take place and the key factor of development, health control just detects the detection information criterion of the perspective health risk assessment on the disease early warning meaning that institute is really expected in the assessment at sub-health population.The biomarker group input computer that certain is individual will be automatically compares the predictive mode of entry information and software and analyze based on the predictive software systems of assessment models, and then determines the trend and the possibility of this individuality generation disease.This process has been created condition for taking proper prophylactic methods.
The sorry part that this kind detects evaluation measures is must include wound property blood biochemistry index and increased inconvenience.
3. cross-synthesis appraisal procedure
In sum, be necessary that means by comprehensive assessment make sublate separately relative merits of the entirely different detection assessment models " hybridization " of above two class generation mechanisms.Because the new model of being constructed derives from " hybridization " of the entirely different source model of two class generation mechanisms; Therefore new model both can not can not help the converging of clinical case of original generation two class models to rebuild by nationality by obtaining synthesizing of two class model algorithms also, can only obtain according to the original sufficient new clinical case of trial design accumulation of the present invention.
Summary of the invention
Health evaluating is to provide individuation inferior health intervention means institute important key link according to health and fitness information in the health control process.Based on the system biological information science, the present invention proposes the total system variable of macroscopical human body, is the teaching standard with the nationality strictness based on EPDML perspective model, and it is shorter to develop the lead time, the cross-synthesis general establishment method and the implement device thereof of the comparatively economic and damage-free type health evaluation model that is easy to apply.And enumerate with compatriots' ICD initiation potential assessment models as the teaching standard control, having developed the assessment models of corresponding nothing wound collaterals of human detected value, the extrapolation forecast result of model has shown the application feasibility of the method.
The objective of the invention is to overcome shortcoming of the prior art, and propose a kind of general establishment method and device thereof of damage-free type health evaluation model.
A kind of general establishment method of damage-free type health evaluation model, its step is corresponding label shown in Fig. 1 process flow diagram: step is as follows:
Step 1: same health evaluating individuality is measured the wound attribute simultaneously and do not have wound attribute and accumulate abundant case, here the sufficient amount of case can not be expressed with stable constant value, and determine by the program recursive procedure of study more shown in Figure 1, what promptly the abundance of the individual case that is accumulated depended on that following step 6 tests whether the extrapolation precision that draws reach setting requires 90%, sees embodiment example (1) and (2) in the following instructions for details;
Step 2: substitution provides assessment result in the wound type epidemiology disease prediction model that has that obtains clinical practice to case by the wound attribute that has that above-mentioned steps 1 measures;
Step 3: the nothing wound attribute that has wound type epidemiology assessment result and above-mentioned steps 1 to measure that synthetic above-mentioned steps 2 is obtained;
Step 4: create attribute and have wound type epidemiology assessment result to constitute the training cases data set of machine learning jointly by above-mentioned steps 3 synthetic nothings;
Step 5: carry out data mining based on machine learning to set up noninvasively estimating model to be tested;
Step 6: substitution is by the nothing wound attribute that measures at new health evaluating individuality as above-mentioned step 1, the nothing wound that promptly never is used to set up noninvasively estimating model to be tested detects the damage-free type assessment models to be tested that value obtains in above-mentioned steps 5 and draws the noninvasively estimating result of this model, compare with the wound type assessment result of obtaining by above-mentioned steps 2 that has of same health evaluating individuality, the total new case number that is used for this extrapolation accuracy test is not less than 2: 8 with the ratio of the total training cases number that is used to set up this noninvasively estimating model to be tested, with the coincidence rate of comparison as the extrapolation precision of damage-free type assessment models to be tested, the extrapolation accuracy test of model by standard for being not less than 90%, being lower than 90% as the precision of extrapolating after tested returns above-mentioned steps 3 and closes the former training cases data set of And and extrapolation accuracy test data set is that new training cases data set is to re-execute step 4-6, until the damage-free type assessment models foundation that conforms with the precision of extrapolate.
A kind of general apparatus for establishing of damage-free type health evaluation model, its ingredient is as follows:
With the personal computer that possesses display device or microcomputer as data processing equipment, under its CPU control, the damage-free type biometric information sensor measures the damage-free type continuous quantity biological information of health evaluating individuality, imports data processing equipment so far through the analog/digital energy converter again; This data processing equipment obtains as healthy questionnaire information class discrete magnitude biological information and finally exports the health evaluating result through the operation of the described computer program of above-mentioned steps 1-6 in display device and printable or do not have paper by the internet and read simultaneously, and offer the health evaluating individuality, realized the closed loop running of this data processing equipment as the information source of this data handling system and reduction point with the health evaluating individuality.
Beneficial effect of the present invention:
Is the teaching standard with the nationality strictness based on EPDML perspective model, and it is shorter to develop the lead time, the comparatively economic and disease Early-warning Model that is easy to apply and preventing trouble before it happens, with respond that present health ministry advocated to prevention " reach " and to the policy of basic unit's " sinking ".
Embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention
Here provide a computer machine study of adopting the system biological information science to obtain the scheme step 1-6 as shown in Figure 1 of the cross-synthesis control test of damage-free type assessment models, individual from health evaluating, by being arranged, the wound type goes out damage-free type health evaluation (disease early warning) model as the teaching standard development based on seasonal effect in time series epidemiology disease prediction model.This model also can constantly be followed the accumulation of clinical case and optimize.Following feasibility illustration as this universal method, summary [sees for details: Wu Yangfeng etc. with compatriots' ischemic cardiovascular assessment models.The appraisal procedure of compatriots' ICD initiation potential and the development research of simple and easy assessment tool, China's cardiovascular disease magazine, 2003,31,12:893-901] in contrast, develop of process and the interpretation of result of corresponding damage-free type based on this macrosystem biomarker group's of collaterals of human detected value assessment models.
Choose achievement in research among the present invention as the outer cardiovascular disease hospital epidemiology Wu Yangfeng of the research department professor of China Concord Medical Science University of above-mentioned Chinese Academy of Medical Sciences angiocardiopathy institute's mound of illustration seminar---the assessment models of compatriots' ICD initiation potential can reflect preferably that the comprehensive danger of cardiovascular disease takes place compatriots, and predict satisfactorily in certain individual following 10 years and suffer from ICD (ischemic cardiovascular diseases, danger classes ICVD).This assessment models is determined jointly by age, blood pressure, body mass index, whether smoking, blood sugar and lipids contents six factors.Age and whether smoking just can obtain by filling in questionnaires in the middle of this six factors, blood pressure can be measured by sphygmomanometer and obtain, body mass index can calculate acquisition again by measuring height and body weight, has only blood sugar and lipids contents could obtain by wound blood drawing chemical examination is arranged.
The cross-synthesis control test scheme of damage-free type assessment models is obtained in computer machine study as shown in Figure 1, has wound type ICVD epidemiology disease prediction model to choose the neuroid algorithm as the teaching standard to realize developing non-invasive health evaluating (disease early warning) model based on the data mining of computer machine study by above; Because the neuroid algorithm is fit to handle the such sensing data that contains complicated noise of similar channels and collaterals skin surface resistance detection value very much.
In this implementation procedure we at first with the channels and collaterals person under inspection's that obtains in 297 routine physical examinations data training set as the neuroid machine learning, and with other 227 data as test set to be used to test the forecast precision of institute's established model.Because training set and test set come from diverse colony on sample time and the place, on statistics, be fully independently therefore.
These testers' data comprise that all whether and the detailed information such as channels and collaterals resistance at 24 main acupuncture points, human body skin surface age, sex, blood pressure, height, body weight, blood pressure and blood lipoid content, smoking.According to the computing method in the angiocardiopathy assessment models (referring to table 3 and table 4), we can calculate each tester's ICVD initiation potential in 10 years futures (%), by with compare with sex section in age in the same year crowd's ICVD morbidity in 10 years futures average dangerous (%), we are defined as the high-risk tendency person of angiocardiopathy to the following 10 years people that surpass with sex section in age in the same year crowd's morbidity average dangerous (%) of ICVD initiation potential (%).For this reason, we have introduced a target variable " whether high-risk " in model, for following 10 years the ICVD initiation potential (%) surpass people, target variable value 1 (high-risk) then, otherwise be 0 (non-high-risk) with sex section in age in the same year crowd's ICVD morbidity in 10 years futures average dangerous (%).As at teaching standard source model---the age, sex, blood pressure, height, body weight, blood pressure and blood lipoid content, the smoking whether corresponding information that obtain in the routine physical examination that 297 data training sets of substitution in the wound assessment models are arranged of compatriots' ICD initiation potential, can draw 0,100 data value of 197 data values 1 and be the teaching standard.Utilization neural network algorithm [14] training obtains model, then again model result is applied to the precision of prediction that forecasts on the test set with testing model.
Neural network model can roughly be expressed as minor function:
Certain body-centered vascular diseases forecast risk " whether high-risk "=f (age, sex, systolic pressure, body mass index, smoking whether, and the channels and collaterals resistance value at 24 main acupuncture points, human body skin surface)
Hence one can see that, and this model is not for comprising the damage-free type model of blood sugar and blood fat.
Predicting the outcome of 227 data test collection is as follows:
(1) uses 297 original data to do the training set training and obtain model, then with being somebody's turn to do
Model is made prediction to 227 data;
Actual prediction

--------+---------+---------+
Amount to 165 62 227
We know from above confusion matrix, at test set altogether in the middle of 227 data, actual value be 167 data of 0 by model prediction after 153 still be that 0,14 wrong report is 1; Actual value be 60 data of 1 by model prediction after 48 still be that 1,12 wrong report is 0.Wherein model prediction value and actual value are coincide 201 data, and what misfit has 26 data, and the predictablity rate of model is 88.55%.
(2) precision of extrapolating after tested is lower than 90% and returns the step 3 of above-mentioned Fig. 1 and close the former training cases data set of And and extrapolation accuracy test data set is that new training cases data set is to re-execute step 4-6, it is the learning process again that the sequential clinical data that progressively increases the accumulation routine physical examination enters a new round, promptly do training set altogether and obtain learning model, then up-to-date other 878 data of obtaining are made prediction with this model with original individual training of 524 (297+227) and test data;
Actual prediction
| 0 | 1 | amount to
--------+---------+---------+
0 | 636 | 31 | 667
--------+---------+---------+
1 | 27 | 184 | 211
--------+---------+---------+
Amount to 663 215 878
We know from above confusion matrix, at test set altogether in the middle of 878 data, actual value be 667 data of 0 by model prediction after 636 still be that 0,31 wrong report is 1; Actual value be 211 data of 1 by model prediction after 184 still be that 1,27 wrong report is 0.Wherein model prediction value and actual value are coincide 820 data, and what misfit has 58 data, and the predictablity rate of model is 93.39%.
Contrast predicting the outcome as can be known of above-mentioned (1), the learning process again that training data continues to increase can make model accuracy be improved constantly and reach set extrapolation accuracy standard, has promptly set up this damage-free type health evaluation model greater than 90%.
