The Clinical Research And Exploration On Treatment Method Of Qufengjiejingqi Ngfeihuatan Against Children’s Cough Variant Asthma

Cough Variant Asthma (CVA), which is a common pediatric clinical disease, is a special type of asthma. The Traditional Chinese Medicine (TCM) theory and clinical studies of the disease is still at its initial stage, and there are different opinions about the cause of disease and study of treatment. We reviewed and summarized the recognizing of etiological factors and pathogenesis of children’s CVA and many recent reports in both fields of TCM and western medicine. Then according to a more comprehensive understanding of recent research and development of TCM treatment against children’s CVA, we systemly study and analyze its etiological factors and pathogenesis characters. Combining the clinical experience of my tutor, we think that the basic mechanism of the children’s CVA is invasion of the lung by wind-phlegm and adverse lung Qi of heat. Base on that character, so we use the basic treatment of expelling wind and resolving tetany、clearing away heat from the lung and resolving phlegm、normalizing qi and downbearing counterflow, we applied Qingfeiqufengzhike prescription to treat 30 children with CVA of invasion of the lung by wind-phlegm and adverse lung Qi of heat, in order to observe the change of clinical syndromes before and after treatment and made an objective evaluation of its effectiveness. At the same time, retrospecting the age, sex, season and the inducement factors of the 30 patients, we discusses the characteristics of 30 CVA children and the advantages of TCM treatment, then we raised that avoiding the morbidity, detailed defense and prolonged treatment are the best treatment for TCM. The results are as follows: the clinical control rate, recovery rate and the total eficiency were respectively 53.3%, 80% and 93.3%. The results of outbreak characteristics: the high outbreak age of this group is 2.5～6.5 years old, especially preschool children. The mainly outbreaking seasons are spring and winter. The children getting allergic disease or their household getting the allergic disease had higher rate of getting the CVA. The first inducement factor was upper respiratory tract infection (66.7%), second was stimulating air(26.67%), and then was exercising factor(13.3 %)and food factors(10%).These results preliminarily indicate that the treatment against the children with CVA of invasion of the lung by wind-phlegm and adverse lung Qi of heat with Qufengzhike prescription, which can improve clinical symptoms and alleviate relapse condition, is an effective and safe method. It also further evidences the understanding of basic pathogenesis and treatment concerning children’s CVA in this article quite agrees with the CVA children’s clinical characteristic and features, therefore it also has the certain value to the clinical practice.
