| Objective: Through the study of lung cancer victims'tongue, the author intend to generalize the characteristic and the regularity of the variation of it, thus can offer certain criterion for further clinical studies.Method: The author suggest the following steps to do the study: first, professional TCM get firsthand information by giving a close watch at the 74 cases of healthy people and 106 cases of lung cancer patient's tongue color, tongue coating and sublingual venae, at set time, quiet, warm environment and in natural light. And then, professional TCM make tongue color classification in accordance with pale tongue, light red tongue, crimson tongue, and green purple ones. TCM classify tongue coating in accordance with thin white coating, thin yellow coating, white and greasy coating, yellow and greasy coating, pestilence. Sublingual venae was categorized by the standard of normal(0 degrees), abnormal degreeâ… , abnormal degreeâ…¡, abnormal degreeâ…¢. Sublingual venae color is sorted into the following groups: lilacinus, purple, green purple, purple black. Second, professional TCM use digital camera (RICHO6, compulsory flash, macro foucallength, IS100) to take the tongue photos of the patients. Third, TCM extract color feature of tongue color and sublingual venae color employing the PLS_TD tongue colorimeter(original version V 3.0)produced by Beijing Precil Mechanic Lit. Using image analysis module tongue RGB (red, green and blue, RGB) system in general information analysis of tongue diagnosis to calculate the tongue and sublingual venae's RGB and then get the H value with the formula.At last, compare the results with normal pairs. Dividing patients according to different clinical syage,pathological type in order to observe their tongue color, tongue coating and sublingual venae and by comparison between the tongue color, tongue coating and sublingual venae, researcher can find regularity or feature of it by analyzing the clinical phenomena, so we can understand the mechanism of its formation and provide scientific material for the diagnose and medical treatment of lung cancer.Result: (1) Compared with healthy group, the normal tongue rate in Lung cancer patients is relatively low. Green purple tongue, greasy coating, pestilence is most; sublingual venae abnormal percentage are much higher than the normal people. The color of it mostly is green purple and purple black. Sublingual venae of the varices are of more serious degree, shown as the trunk clear, vascular rough with blood or ecchymosis. (2)As the change of the illness, different clinical stage patients performs obvious feature. Most of The lung cancer patients inâ… ,â…¡term are light red tongue , thin white in tongue coating, 0 degrees in sublingual venae obviously higher than the others . Most of The lung cancer patients inâ…¢,â…£term are crimson tongue , green purple tongue and green purple in sublingual venae. The abnormal degree of sublingual venae inâ…¢,â…£term more higher than inâ… ,â…¡term. (3)Of all the different pathology type patients, squamous cell carcinoma patients with green purple tongue and greasy coating are at the highest positive rate; the crimson tongue, greasy coating and pestilence is most in Adenocarcinoma patients. Small cell lung cancer patients with sublingual venaeâ… degrees are at the highest positive rate,the sublingual venaeâ…¡degrees is most in Adenocarcinoma patients. The abnormal sublingual venae is most in squamous cell carcinoma patients; squamous cell carcinoma patients and Adenocarcinoma patients with green purple sublingual venae are at the highest positive rate. The light red tongue color of the Alveolar cell carcinoma patient is more likely to be seen. No distinct difference has been noticed among the rest. (4)The G value and the B value are lower of tongue color in the Lung Cancer, R, H values with no significant difference between the normal group. The R value and the G value are lower in sublingual venae color in the Lung Cancer victims. B values with no significant difference between the normal group, H value higher.Conclusion: Tongue diagnose is an important diagnose method in Chinese clinical practice for its precious value in such aspects as economical, easy to be applied etc. The experimental research shows that: (1)Lung cancer patients from clinical stageâ… stage toâ…£stage , with the progress of the disease , tongue color from light red, crimson tongue gradually developed into green purple; Squamous cell carcinoma and small cell lung cancer are mainly green purple tongue. adenocarcinoma are mostly crimson tongue. alveolar cell carcinoma is often light red tongue. (2) Lung cancer patients'tongue is often of greasy coating and pestilence; with the worsen of the disease, from clinical stageâ… stage to stageâ…£, tongue coating from thin white coating gradually developed into greasy coating; squamous cell carcinoma are often of greasy coating, adenocarcinoma are of pestilence. (3)The abnormal degree of sublingual venae in lung cancer patients are higher than the normal person,and sublingual venae are often green purple, purple black. With the deterioration of the disease, the degree of abnormality and darker color gradually increase. (4) The G value and the B value are lower of tongue color in the Lung Cancer victims, R, H values with no significant difference with the normal group. The R value and the G value are lower of sublingual venae color in the Lung Cancer and gradually downward as the disease develops. B values with no significant difference with the normal group, H value higher.In summary, the experimental observation of patients with lung cancer sums up the characteristics of the tongue and make a preliminary study in its formation and clinical significance, such as lung cancer diagnosis, clinical treatment provide a reference target. |
