Abstract:

This paper summarizes Professor Chang Ke's experience in treating damp-heat syndrome of mycoplasma pneumoniae pneumonia in children with the method of Xuanbi Huazhuo. The core pathogenesis of this disease is that damp-heat stagnates and suppresses clear yang, condenses to form phlegm, and obstructs the lung collaterals. At the beginning, it is due to the stagnation of lung qi and failure in diffusion and descent, leading to the internal retention of dampness and fluid; then, the stagnated dampness turns into heat, which goes upward to the lungs; damp and heat binds together, generating phlegm and turbidity and blocking the lung collaterals, which is the key to the pathological changes. Eventually, damp, heat, phlegm and turbidity interacts with each other. Clinically, there are symptoms such as persistent fever, severe cough with much phlegm, nasal congestion, shortness of breath, chest tightness and phlegm congestion. Some children also have symptoms of damp-heat in the middle jiao, such as nausea and vomiting, poor appetite, yellowish-white or yellow-greasy tongue coating. In view of this, Xuanbi Huazhuo is the main treatment method. The self-made "Xuanjing decoction" is taken orally. It is composed of Shangjiao Xuanbi decoction (decoction for relieving obstruction in the upper Jiao) which can promote the flow of qi, resolve dampness and clear heat, combined with Qianjin Weijing decoction which can clear the lung, resolve phlegm, remove blood stasis and expel turbidity. Almond is added to enhance the functions of dispersing, descending and relieving cough, and talc is added to strengthen the clearing and draining of damp-heat. The whole prescription aims to dredge the obstruction of lung qi and clear away damp-heat, phlegm and turbidity. The empirical formula "Fuxiong powder" for external application helps to dredge the lung collaterals, warm and resolve phlegm and turbidity, disperse stagnation and promote qi flow. This treatment method focuses on the core of damp-heat, phlegm and turbidity obstructing the lung collaterals. It addresses the root cause of the stubborn turbidity by internally dredging the stagnation of qi in the lung collaterals; externally, it diffuses and penetrates through the skin, membranes and interstitial spaces, loosening the phlegm and blood stasis, thus launching a three-dimensional attack on "bi(obstruction)" and "zhuo(turbidity)". Clinical practice has confirmed that it can effectively relieve symptoms, which embodies the characteristics of traditional Chinese medicine in the treatment of this disease and the academic thoughts of Professor Chang Ke.
