Expression pattern clustering analyses of the differential genes and miRNAs identified in the PDHS and PQDS populations. a Veen diagrams detailing the differential genes and miRNAs found in the leukocytes and serums. b hierarchical clustering (HCL) analyses of expression profiles of the differential miRNAs in leukocytes. c HCL analyses of expression profiles of the differential genes in leukocytes. d HCL analyses of expression profiles of the differential miRNAs in the serums. Control healthy individuals, PQDS chronic atrophic gastritis patients with Pi-qi-deficiency syndrome, PDHS chronic atrophic gastritis patients with Pi-wei damp-heat syndrome
