To explore the feasibility of Qingfei Paidu decoction in the prevention and treatment of sudden epidemic pulmonary infection from the perspective of"Jue heat overcomes the complex,Yin and Yang are complicated"
Traditional Chinese medicine has a long history of treating epidemic diseases.Numerous references are available.As early as the Yellow Emperor's Classic of Internal Medicine-Su Wen Chapter mentioned:"the five epidemics are all similar,regardless of their size,and the symptoms are similar".In the prevention and treatment of the coronavirus disease 2019(COVID-19),Chinese medicine has shown its unique advantages.Pulmonary infection is one of the most common diseases associated with sudden epidemic diseases,which is mostly induced by various infectious factors such as epidemic bacteria or viruses.If the patient has a history of chronic lung disease,it will further aggravate the clinical symptoms,and is easy to develop into severe pneumonia,with high mortality,rapid progress,long course of treatment,poor prognosis,and many complications,and the general antibiotic application is not as effective as desired."Jue heat overcomes the complex,Yin and Yang are complicated"comes from the chapter of Jueyin disease in Shanghan Lun(Treatise on Febrile Diseases),which is one of the typical features of fever occurring from illness to Jueyin.To explore the correlation between Jueyin disease and the pathogenesis of severe pneumonia from multiple angles,analyze the mechanism of Qingfei Paidu decoction in the treatment of Jueyin fever,better understand the essence of Zhang Zhongjing's prescription,and provide new ideas for the syndrome differentiation process of patients with pulmonary infection caused by epidemic diseases.At present,the prevention and control mechanism of COVID-19 in China has been gradually improved,the number of patients with COVID-19 has been gradually reduced,and the epidemic situation is easing.However,even so,it is still impossible to predict whether sudden and major epidemic diseases similar to COVID-19 will break out again in the future.
