Primary membranous nephropathy is a kidney-specific and autoimmune glomerular disease.Professor GAO Yanbin argues that primary membranous nephropathy belongs to collateral disease in traditional Chinese medicine,which has the nature of deficiency in root and excess in manifestation.The disease undergoes a deficiency-deficient period and a deficiency-failure period.Professor GAO Yanbin advocates “determining the type by deficiency and the syndrome by excess”.The deficiency syndrome is divided into spleen-kidney qi deficiency,lung-spleen qi deficiency,spleen-kidney yang deficiency,yin-yang deficiency,and heart-kidney yang deficiency.The excess syndrome is divided into damp-heat congestion,damp turbidity,latent wind and damp,static blood and damp,and static blood and toxin damage to the kidney collaterals.In terms of treatment,syndrome differentiation by stages was combined with syndrome differentiation and treatment,so as to strengthen the body,eliminate pathogenic factors,and flexibly use Tongluo method during the whole process.
