Research On The Correlation Between TCM Syndrome Types Of Pneumonia Of Children And Pulmonary Function

Objective:To explore the correlation between TCM syndrome types and pulmonary function index of pneumonia of children,and to study the objective law of TCM syndrome differentiation and treatment.Methods:From January 2020 to January 2021,241 hospitalized children who were admitted to the pediatric department of Xiamen Hospital of Traditional Chinese Medicine and met the diagnostic criteria of children’s pneumonia and the criteria of common syndrome differentiation of children’s pneumonia of TCM were collected.Classification of TCM syndrome differentiation and detection of pulmonary function at admission（age 3-5 years old,impulse oscillometry pulmonary function examination;age 6-14 years old,pulmonary ventilation function examination）was analyzed by statistical analysis.Results:1.General data analysis:（1）Of the 241 cases collected in this study,119 cases were male,accounting for 49.4%;122 cases were female,accounting for 50.6%.The gender ratio is0.98:1.Statistical analysis showed that there was no significant difference between different genders（P>0.05）.（2）Of the 241 cases collected in this study,150 cases were aged 3 to 5years old,accounting for 62.2%of the total;91 cases were aged 6 to 14 years,accounting for37.8%of the total,with a higher incidence rate in the younger age group.（3）The course of the five types of syndromes was prolonged in order,the wind-cold blocking lung syndrome was the shortest,the lung and spleen deficiency syndrome was the longest,and the course distribution of each type was statistically different（P<0.05）.2.Analysis of pulmonary function examination results:the abnormal rate of impulse oscillometry pulmonary function examination is 43.3%,the abnormal rate of pulmonary ventilation function examination is 79.1%,the total abnormal rate of pulmonary function examination is 56.8%,and more than half of the children with pneumonia have abnormal pulmonary function examination results.3.Distribution of syndrome types:The TCM syndrome types of 241 cases collected in this study were counted and arranged in order of their constituent ratios,which were as follows:150 cases of wind-heat blocking lung syndrome,accounting for 62.2%of the total number;50 cases of phlegm-heat blocking lung syndrome,accounting for 20.7%of the total number;34 cases of wind-cold blocking lung syndrome,accounting for 14.1%of the total number;4 cases of lung and spleen deficiency syndrome,accounting for 1.7%of the total number;and 3 cases of Yin deficiency lung heat syndrome,accounting for 1.2%of the total number.Among them,234 cases were positive syndrome,accounting for 97.1%of the total number,7 cases were negative syndrome,accounting for 2.9%.Wind-heat blocking lung syndrome was more common in different age groups.4.Analysis of the correlation between TCM syndrome type and pulmonary ventilation function:（1）The FVC,FEV1,FEV1%,PEF,FEF₂₅,FEF₅₀,FEF₇₅,MMEF of wind-cold blocking lung syndrome are lower than those of wind-heat blocking lung syndrome,and there are statistical differences in all indicators（P<0.05）.（2）There was no statistical difference between wind-cold blocking lung syndrome and phlegm-heat blocking lung syndrome（P>0.05）.（3）The FEV1%,PEF,FEF₂₅,FEF₅₀,FEF₇₅,MMEF of phlegm-heat blocking lung syndrome were lower than those of wind-heat blocking lung syndrome,and there were statistical differences in all indexes（P<0.05）,but no statistical differences in FVC and FEV1（P>0.05）.5.Analysis of correlation between TCM syndrome type and impulse oscillometry pulmonary function:（1）The R5,R20 and Fres of wind-cold blocking lung syndrome were higher than those of wind-heat blocking lung syndrome,with statistical significance（P<0.05）.（2）There was no statistical difference between R5,R20 and Fres（P>0.05）in wind-cold blocking lung syndrome and phlegm-heat blocking lung syndrome.（3）The R5 and Fres of phlegm-heat blocking lung syndrome were higher than those of wind-heat blocking lung syndrome,and the difference was statistically significant（P<0.05）,but there was no statistical difference in R20（P>0.05）.The main difference between the two was small airway resistance（R5-R20）.6.There is a good consistency in airway resistance between pulmonary ventilation function and impulse oscillometry pulmonary function examination.（1）The degree of decrease of large and small airway function in wind-cold blocking lung syndrome is more obvious than that in wind-heat blocking lung syndrome,that is,the resistance of large and small airways in wind-cold blocking lung syndrome is higher than that in wind-heat blocking lung syndrome.（2）The degree of decrease of large and small airways function in wind-cold blocking lung syndrome is similar to that in phlegm-heat blocking lung syndrome,that is,there is no obvious difference between them in airways resistance.（3）The function of small airways in the syndrome of phlegm-heat blocking lung is more obvious than that in wind-heat blocking lung,that is,the resistance of small airways in phlegm-heat blocking lung syndrome is higher than that in wind-heat blocking lung.Conclusion:1.wind-heat blocking lung syndrome was the most common syndrome in children’s pneumonia.Secondly,the syndrome of phlegm-heat blocking lung and wind-cold blocking lung.Yin deficiency lung heat syndrome and lung and spleen deficiency syndrome less.2.There are differences in pulmonary function indexes among different syndromes of children’s pneumonia,and the difference is significant by statistics.Pulmonary function examination can provide some reference for syndrome differentiation and treatment of children’s pneumonia.
