| Objective:The purpose of this study is to collect the symptom information of the etiology of chronic urticaria for syndrome differentiation,collect the tongue diagnosis information of patients with chronic urticaria with traditional Chinese medicine tongue diagnostic instrument,make data statistics and analysis,and study and analyze the correlation between the tongue characteristics of patients with chronic urticaria and TCM syndrome differentiation.To understand the feasibility and clinical value of objectification of tongue diagnosis information in the clinical diagnosis and treatment of chronic urticaria,in order to help improve the syndrome differentiation of chronic urticaria and provide relevant data for the objectification of tongue diagnosis.Methods:Patients with chronic urticaria were randomly collected from the dermatology clinic of the Affiliated Hospital of Chengdu University of traditional Chinese medicine.After signing the informed consent,the scale information and tongue diagnosis information were collected.The general information such as gender,age,skin temperature,wheal color and UAS score were collected through the scale for syndrome differentiation.The tongue image information of patients was collected by tongue diagnostic instrument,and the above information was compared and statistically analyzed.(1)Methods of syndrome differentiation and typing of traditional Chinese medicine: syndrome differentiation and typing is carried out according to the general situation,clinical consultation,specialty situation,scale and other information of patients in combination with teaching materials,literature,research reports and other materials.(2)Tongue image acquisition includes: tongue color,tongue shape,fur color,fur quality,and RGB,lab and HSV count values oftongue color and fur color.Results:1.General information: among 199 subjects,gender: 63 male patients(31.7%)and 136 female patients(68.3%),with a male to female ratio of about 0.46:1.Age: young patients account for about 43.2%,middle-aged patients account for about 38.1%,and most of them are young and middle-aged women..2.Specialty situation: among 199 subjects,59% of patients had no obvious abnormality in skin temperature during the onset of chronic urticaria,and 40% of patients consciously increased skin temperature.In 56% of patients,the color of wind mass at the onset of Cu was light red,bright red or tide red accounted for 36%,and the skin lesions of a few patients were pale white(7%)or dark red(1%).According to the score of Cu pruritus count,51% ofpatients felt moderate pruritus,31%ofpatients felt moderate pruritus and 18% ofpatients felt mild pruritus.3.Syndrome differentiation of traditional Chinese medicine: It was found that the patients with spleen deficiency and dampness stagnation syndrome(49%)were the most,followed by dampness heat accumulation syndrome(21%),qi stagnation and blood stasis syndrome accounted for 10%,lung spleen qi deficiency syndrome accounted for 7%,blood deficiency and wind dryness syndrome,Qi and blood deficiency respectively accounted for 5%,and exterior deficiency and unconsolidated syndrome accounted for 3%.4.Tongue image:(1)Tongue color: among the subjects,there were more light red tongue(32%)and light purple tongue(21%).The average change of R value in different syndrome types suggests that R value is gradually increasing with the decrease of thermal image.G.The change of B value suggests that when the disease has blood stasis,G and b values increase,and the tongue color is purple and dark.With the increase of L value,the disease changes from excess syndrome to deficiency syndrome.The change of a value in different syndrome types suggests that with the decrease of a value,the thermal image subsides.B value has little difference in different syndrome types,which is not statistically significant.H value can indicate the change process of thermal image.The higher the H value,the lighter the tongue color.On the contrary,the redder the tongue color,the heavier the thermal image.S.The change of V value from small to large suggests the change process of disease from demonstration to deficiency syndrome.(2)Tongue shape: among the subjects,normal tongue shape was the most(26.6%),followed by fat tongue(18.6%)and tooth mark tongue(15.1%).Fat tongue and tooth mark tongue dominate spleen deficiency and dampness excess,both of which are found in spleen deficiency dampness stagnation syndrome,which is consistent with the spleen deficiency dampness stagnation syndrome most seen in the results of syndrome differentiation.(3)Moss color: Yellow moss,white moss and gray black moss can be seen in the moss color of the subjects.The change of RGB value in different syndrome types suggests that yellow fur is seen in excess heat syndrome,white fur is more seen in deficiency syndrome,and gray black fur is seen in scattered syndrome.The higher the L value,the brighter the color,which means that the thicker and greasy the tongue coating,the L value can be used to guide the evaluation of the healing degree of the tongue coating from thick and greasy to thin.A value has little difference in different syndrome types and has no statistical significance.The greater the b value,the yellow fur color and excess heat syndrome The value of B is the largest.S.The higher the V value,the thicker and greasy the tongue coating,and the smaller the s and V values,the thinner the tongue coating.(4)Fur quality: among the subjects,thick and greasy fur was the most(80%),followed by thin fur(15%),greasy fur(2%),flower peeling fur(2%)and thick fur(1%).It is consistent with the most patients with spleen deficiency and dampness accumulation syndrome in clinical syndrome differentiation.In the distribution of fur quality of different syndrome types,thin fur is found in deficiency syndrome or light evil Qi,and thick greasy fur is found in phlegm dampness,internal heat and other syndromes.Moss rot is found in phlegm.Moss peeling can be seen in the deficiency of both qi and blood.It can be seen that the fur quality is consistent with the syndrome differentiation elements of syndrome types.Conclusions:The incidence rate of chronic urticaria is higher among young and middle-aged women.The syndrome differentiation of chronic urticaria can be divided into spleen deficiency and dampness stagnation syndrome,damp heat accumulation syndrome,qi stagnation and blood stasis syndrome,lung spleen qi deficiency syndrome,blood deficiency and wind dryness syndrome,Qi and blood deficiency syndrome and exterior deficiency and instability syndrome,among which the patients with spleen deficiency and dampness stagnation syndrome are the most.The information of tongue color,tongue shape,coating color and coating quality collected by tongue diagnostic instrument has a certain correlation with the syndrome type elements of clinical syndrome differentiation from counting data to results.Objectification of tongue diagnosis and chronic urticaria deserve further study. |
