Correlation Between Infection Site Of Infectious Cough And TCM Syndrome And Cough Characteristics

On the basis of literature review,this paper focused on the locations and TCM syndromes of infectious cough and their correlations with cough characteristics.Objective:Using the theory and method of acoustics and phonetics to study sound characteristics of patients with upper respiratory tract infection,acute tracheal bronchitis and pulmonary infection,and then explore the the relationship between the digital index of cough and the position and syndrome of cough.Methods:Referring to the latest Chinese and Western Medicine coughing guidelines to design cough case questionnaire.Patients with the upper respiratory tract infection,acute tracheal bronchitis and pulmonary infection of 18 to 85 years old in the respiration outpatient department and ward of Dongzhimen hospital were selected as the research objects.Recorded their symptoms,signs,and auxiliary examination results,at the same time collected their original cough data.And then used the Praat phonetics software to digitize the time and frequency domain indicators of cough.Used the SPSS 20.0 software to conduct statistical analysis of multiple samples,and got the statistical relationship between the cough sound index and the disease position and TCM Syndrome.In order to provide a more effective method in clinical disease differentiation,syndrome differentiation and treatment for modern digital voice assisted Chinese and Western medicine.Result:1.The prevalence of acute tracheal bronchitis was the highest.The probability of upper respiratory infection in men were higher than women.There was no significant statistical difference in sex distribution in different parts of the disease(P>0.05).The prevalence of upper respiratory tract infection gradually decreased with age.The prevalence of community-acquired pneumonia increased with age.The prevalence of tracheal bronchitis was major in young people and elderly people.There was no significant statistical difference in age distribution between different parts of the disease(P>0.05).2.There were more wind Sheng spasm syndrome and less phlegm heat stagnation of the lung syndrome.The male phlegm heat stagnation of the lung syndrome were more than women.There was no significant statistical difference in sex distribution between different TCM syndrome types(P>0.05).With the increase of age,the wind Sheng spasm syndrome ratio showed a decreasing trend.Middle aged people were in the middle transition zone,the ratio of each type of syndrome was between the young and the elderly.There was no significant statistical difference in age distribution of different TCM syndrome types(P>0.05).3.Upper respiratory tract infection were most with wind Sheng spasm syndrome.Community acquired pneumonia were most with phlegm heat stagnation of the lung syndrome.The two syndromes of acute tracheal bronchitis were relatively close.There were significant statistical differences in the distribution of TCM Syndrome Types(P<0.01).4.Pitch,format 1,centre of gravity,skewness,kurtosis,mean,offset,band energy difference,standard deviation(Hz),standard deviation(dB)9 indicators were all P<0.05 with statistical significance.And pitch,centre of gravity,kurtosis,mean were P<0.01.All the indexes of TCM syndrome type were P>0.05,with no statistical significance.Conclusions:1.During the current study period,there were more wind Sheng spasm syndrome,and fewer phlegm heat stagnation of the lung syndrome.The more close to the lower respiratory tract,the more phlegm heat stagnation of the lung syndrome.The more close to the higher respiratory tract,the more wind Sheng spasm syndrome.People with weak physical quality suffered more from community acquired pneumonia and phlegm heat stagnation of the lung syndrome.People with strong physical quality were more infected with respiratory tract infection and wind Sheng spasm syndrome.2.Mean,offset,band energy difference,format 1,pitch,centre of gravity,skewness,kurtosis,standard deviation(Hz)9 indicators could distinguish different parts of the respiratory tract infection.The closer to the lower respiratory tract,the more concentrated the energy and frequency were in the lower range,reflecting the low voice characteristics of the lower respiratory tract cough.The closer to the upper respiratory tract,the more energy and frequency dispersed to the higher range,reflecting the high voice characteristics of the upper respiratory tract cough.
