Detailed Implementation
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application; the terms "comprising" and "having," and any variations thereof, in the specification and the foregoing drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification and the foregoing drawings are used to distinguish different objects, not to describe a particular order.
[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0021] It should be noted that dyslipidemia is a common modern disease and a major risk factor in the development of atherosclerotic cardiovascular disease (ASCVD), as well as a risk factor for many metabolic diseases and chronic diseases. Therefore, the prevention and treatment of dyslipidemia is often used as a key measure in chronic disease control and health management, and as an entry point for preventative healthcare. With social development and improved living standards, people's lifestyles, pace of life, and psychological stress have undergone significant changes, leading to a year-on-year increase in the number of dyslipidemia patients in my country. In the past 30 years, the prevalence of dyslipidemia in the Chinese population has reached 40.40%, a significant increase from previous years. The affected population is gradually becoming younger, and the number of cases is expanding annually. It is expected that the differences in the affected regions and the composition of dyslipidemia will gradually narrow. Therefore, early detection and prevention help reduce the risk of morbidity and mortality from dyslipidemia-related diseases. Applying modern scientific methods to assist in the diagnosis and treatment of dyslipidemia is of great significance. Infrared thermal imaging (IRT) is a non-invasive, safe, and inexpensive imaging technique for assessing surface temperature. Figure 1 Infrared thermography, to a certain extent, reflects the body's energy metabolism. By observing changes in human body radiation energy, the patterns of disease progression can be studied. Infrared thermography directly reflects the changes in the yin-yang and cold-heat states of the body's internal organs and meridians, making TCM syndrome differentiation dynamic, visual, and objective, and providing a basis for standardized and objective diagnosis in TCM syndrome differentiation and disease differentiation. However, there is currently no TCM infrared detection standard for dyslipidemia, a lack of unified operating procedures, and a lack of qualitative and quantitative analysis of thermograms from patients with dyslipidemia.

[0057] Infrared thermographic characteristics of individuals with dyslipidemia: Segmental increases in metabolic heat are often visible in the fingers, resembling a "skewer of candied hawthorns," with the metabolic heat increasing in a stepwise manner from the little finger to the thumb. Figure 2-1 , 2-2 2-3), occasional punctate or patchy increases in metabolic heat were observed in the liver area ( Figure 2-3 ), lumpy areas of low metabolic heat were observed in the epigastric region and around the navel. Figure 2-1 Some patients were overweight. Through collecting and observing data from 360 cases of dyslipidemia with different syndromes over the past three years, it was found that in addition to the visible changes in temperature on the fingers, the abdominal temperature of people with dyslipidemia was often lower than that of people with normal blood lipids. Observation of specific abdominal areas revealed that changes in the temperature of the Zhongwan (CV12) area and the temperature in the area from Zhongwan to Shenque (CV8) were most strongly correlated with dyslipidemia. The optimal temperature cutoff point for diagnosing dyslipidemia at Zhongwan was 33.825℃, with an area under the curve (AUC) of 0.772 (P < 0.01), a sensitivity of 77.8%, and a specificity of 70%. The optimal temperature cutoff point for the average temperature in the Zhongwan to Shenque area was 33.165℃, with an AUC of 0.740 (P < 0.01), a sensitivity of 65.6%, and a specificity of 75%. The optimal temperature cutoff point for Shenque (CV8) was 34.25℃, the area under the curve (AUC) was 0.702 (P < 0.01), the sensitivity was 62.5%, and the specificity was 70%. Infrared thermographic characteristics of six types of dyslipidemia patients (1) Damp-heat accumulation Infrared thermal imaging findings: In addition to exhibiting infrared characteristics of dyslipidemia ( Figure 3-1 The entire body shows clumps of high-temperature metabolic thermogram changes. Although the body shape is overweight, clumps of high-temperature thermograms are still visible in the abdominal fat accumulation area. Figure 3-2 , 3-3 The level of the middle jiao was slightly higher than that of the spleen deficiency and dampness group and the spleen and kidney yang deficiency group; clinical features: dizziness, dry mouth, bitter taste, obesity, irritability, dry stool and dark urine; other clinical manifestations: fatigue, red tongue, yellow and greasy coating, and wiry and slippery pulse. (2) Infrared thermographic manifestations of phlegm-dampness obstruction: In addition to the infrared characteristics of dyslipidemia ( Figure 4-1 Low-temperature clumps were visible on the front of the torso (lower temperature areas: abdomen, lower abdomen, and lower abdomen) and back, and even on the limbs. Higher temperature changes were observed on the lips, nose, and extremities. Figure 4-2 ,4-3); Clinical features: fullness and discomfort in the chest and epigastrium, poor appetite, dizziness and heaviness in the body; Other clinical manifestations: constipation, white and greasy tongue coating, and a soft and slippery pulse. (3) Phlegm and blood stasis in infrared thermogram: In addition to the infrared characteristics of dyslipidemia ( Figure 5-1 This shows infrared thermographic manifestations similar to those of phlegm-dampness obstruction, while the body also exhibits asymmetrical thermographic distribution. Figure 5-2 , 5-3 Clinical features: dizziness, heaviness in the body, chest and rib distension, numbness in the limbs, dry mouth and poor appetite; other clinical manifestations: incomplete bowel movements, dark red or purplish tongue with ecchymosis, and wiry and slippery or thin and hesitant pulse.
[0058] (4) Infrared thermogram manifestations of spleen deficiency and dampness: In addition to the infrared characteristics of dyslipidemia ( Figure 6-1 The temperature in the abdominal area is relatively low. Figure 6-2 ), second only to the spleen and kidney yang deficiency group, and also showing mass-like low metabolic temperature patterns on the trunk ( Figure 6-3 Clinical features: fatigue, heaviness of the body, abdominal distension, poor appetite, loose stools; other clinical manifestations: dizziness, pale and swollen tongue with teeth marks on the sides, and a soft and slow pulse.
[0059] (5) Infrared thermographic manifestations of liver and kidney yin deficiency: In addition to the infrared characteristics of dyslipidemia ( Figure 7-1 The temperature of the Ren meridian is slightly higher, and the temperature of the Zhongwan acupoint is the highest compared to the other five syndrome types, or it is manifested as punctate, linear, or patchy increases in metabolic heat in the neck, palms, and upper chest. Figure 7-2 Elevated metabolic temperature can also be seen in the head and face; clinical features: soreness and weakness of the lower back and knees, dry mouth and throat, dizziness and tinnitus, hot palms and soles; other clinical manifestations: dull pain in the right hypochondrium, red tongue with little coating, and wiry and thready pulse.
[0060] (6) Infrared thermogram manifestations of spleen and kidney yang deficiency: In addition to the infrared characteristics of dyslipidemia ( Figure 8-1 The metabolic temperature at Shenque and Zhongwan acupoints was the lowest among the six syndrome types. Low temperature could also be observed in the nose, extremities, abdomen, and kidney area. Figure 8-2 , 8-3 (8-4), some areas of slightly high temperature are visible in the neck and shoulders, indicating that deficiency fire is rising upwards ( Figure 8-3 Clinical features: soreness and weakness of the lower back and knees, aversion to cold and cold limbs, abdominal distension and bloating, frequent urination at night, loose stools; other clinical manifestations: pale tongue, thin white coating, deep and slow pulse; In summary, the main internal cause of dyslipidemia is the dysfunction of the liver, spleen, and kidneys. Phlegm and blood stasis are both pathological products and key pathogenic mechanisms. The normal functioning of the internal organs depends on the smooth flow of the three jiaos (upper, middle, and lower burners). The middle jiao connects the upper and lower parts of the body and is the hub for the ascending and descending of qi in the internal organs and the vital energy circulation of the meridians. It is responsible for receiving, transmitting, and transforming qi. If the middle jiao is blocked, qi will be obstructed, which will easily lead to the generation of phlegm and dampness and blood stasis in the meridians. "The middle jiao is located in the stomach and the middle jiao." The middle jiao is located in the middle jiao and is the meeting point of the fu organs and the junction of the spleen. It has the function of building up the middle earth and is in charge of the spleen and stomach. The spleen is located between the heart, lungs, liver, and kidneys, which corresponds to the upper, middle, and lower jiaos. "Where evil gathers, qi must be deficient." People with dyslipidemia have abnormal middle jiao transformation and transportation, and the temperature of the middle jiao acupoint area is lower than that of people with normal blood lipids. Infrared thermography can intuitively reflect the changes in the yin-yang and cold-heat states of the human body's internal organs and meridians, making TCM syndrome differentiation dynamic, visual, and objective, and providing a basis for the standardization and objectification of TCM syndrome differentiation and disease differentiation.
