Professor SHI Zhenggang believes that pediatric tic disorders primarily affect the heart and liver,with pathological factors including phlegm,fire,and wind.The basic pathogenesis involves phlegm-fire stirring up liver wind,which disturbs the mind.Among these,phlegm-fire is the macro factor,and wind movement is the micro factor.The treatment focuses on clearing heat,resolving phlegm,calming the liver and stopping wind,soothing convulsions,and calming the nerves,using a modified Changpu Yujin Tang(菖蒲郁金汤),which has achieved satisfactory clin-ical efficacy.Professor SHI integrates the"macro-dialectical"thinking of traditional Chinese medicine(TCM)with the"micro-targeting"treatment of Western medicine,emphasizing the regulation of the body's state from a macro perspective,where the external environment is equivalent to constitution,allowing the body to"resolve phlegm and extinguish fire"to achieve the purpose of calming liver wind.Furthermore,he targets a series of wind-related symp-toms,which involves a more precise approach to changes in disease symptoms and physicochemical indicators,for targeted treatment to drive out external wind and calm internal wind.A clinical case is attached for verification.
