Embodiment 1

[0036] Embodiment 1 Tongue Image Image Acquisition Specification (Attachment: Acquisition of Tongue Image Parameter Numerical Values)

[0037] 1. TDA-1 small tongue imager is selected as the tongue image acquisition device, such as patent number: CN201020543888.0 Acquisition time: 1:00-4:30pm. The tongue imager can adopt the "miniature hand-held tongue image acquisition device" described in the following utility model patent, patent number: 201020543888.0. Such as figure 2 and image 3 As shown, the tongue imager includes a detachable collection ring 1, a UV mirror 2, an LED light source 3, a camera module 4, a camera button 5, a handle 6, an LED light source switch 7, a circuit board 8, a retractable cylinder 9, and an operation panel 10 , Power switch 11. The detachable collection ring 1 is fixedly connected to the outside of the front end of the telescopic tube 9, the UV mirror 2 is fixed to the front end of the inner surface of the telescopic tube 9, the LED light sour...

[0046] Example 2 Selection of Tongue Image Parameters Related to Glucose Metabolism

[0047] 1. Case collection

[0048] A total of 290 patients with diabetes mellitus who visited the endocrinology department of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine were collected. Among them, there were 149 males and 141 females, with an average age of (57.1±9.8) years, an average disease duration of (10.4±7.9) years, and an average Body Mass Index (25.1±4.4) kg / m 2 .

[0049] Inclusion criteria: ① meet the diagnostic criteria for diabetes and belong to type 1 or type 2; 2) aged between 18 and 70; 3) sign the informed consent. Exclusion criteria: 1) Long-term use of hormonal drugs (glucocorticoids, thyroxine, etc.); 2) Women during menstruation; 3) Abnormal hematopoietic system; 4) Folic acid and vitamin B12 deficiency; 5) Taking antibiotics in the past 1 month; 6) Glossitis and other diseases affecting the tongue in the past; 7) Diabetic patie...

Embodiment 3

[0062] Embodiment 3 Establishment of Tongue Image Parameters Multiple Regression Mathematical Model

[0063] The case collection method is the same as in Example 2.

[0064] Selection of candidate tongue image parameters: According to the results of correlation analysis in Example 2, select zhiS, zhiLa, taiS, taiLa, taiLb, taiCr, taiASM, zhiG, zhiB, zhiI, zhiL, zhiY, taiR, taiG, taiB, taiI, taiL, taiY, taiCb, zhiCON, zhiENT, zhiMEAN; taiCON, taiENT, taiMEAN were used as candidate variables for establishing multiple regression mathematical models.

[0065] Mathematical model establishment method:

[0066] Using SPSS19.0 software, using the Regression command, with HbA1c as the dependent variable and the candidate variable as the independent variable, select the enter mode to try to establish a mathematical model. Based on the P value of each independent variable, the independent variable with the largest P value was removed each time, and the mathematical model was re-establi...

Abstract

The invention discloses a tongue diagnosis system for screening diabetes. The tongue diagnosis system comprises a tongue picture instrument, a tongue picture parameter obtaining module, a blood glucose parameter and tongue picture parameter correlation analysis module, a multiple regression mathematic model establishing module and a diabetes suffering value tangency point determining module, wherein the tongue picture parameter obtaining module is used for receiving a tongue picture image collected by the tongue picture instrument and obtaining tongue picture parameters; the blood glucose parameter and tongue picture parameter correlation analysis module is used for receiving the tongue picture parameters, carrying out correlation analysis on the tongue picture parameters and blood glucose parameters and obtaining tongue picture parameters related to glycometabolism; the multiple regression mathematic model establishing module is used for receiving the tongue picture parameters related to the glycometabolism and establishing a multiple regression mathematic model; the diabetes suffering value tangency point determining module is used for collecting the tongue picture parameters, comparing the tongue picture parameters with a golden standard of a diabetes diagnosis method and determining a diabetes suffering value tangency point. The tongue diagnosis system disclosed by the invention has better accuracy and flexibility in diabetes screening, and compared with a traditional method, the tongue diagnosis system is simpler, more convenient and economic and is good in practicability.

Description

technical field [0001] The invention belongs to the field of disease screening, relates to the technical field of diabetes screening, in particular to a tongue diagnosis system for screening diabetes. Background technique [0002] In the past 30 years, the prevalence of diabetes in my country has increased significantly. In 1980, the epidemiological data of 300,000 people in 14 provinces and cities nationwide showed that the prevalence of diabetes was 0.67%. From 1994 to 1995, an epidemiological survey of diabetes was conducted among 210,000 people in 19 provinces and cities nationwide. The prevalence of diabetes in the 25-64 age group was 2.5%, and the prevalence of impaired glucose tolerance (IGT) was 3.2%. The prevalence of diabetes has become more serious in the last 10 years. The 2002 National Nutrition Survey found that among people over the age of 18, the prevalence of diabetes in the urban population was 4.5%, and that in rural areas was 1.8%. The prevalence rates...
