The invention belongs to the technical field of biological
medicine, a series of differential miRNAs and intestinal strains are innovatively screened out in a patient
queue by applying intestinal
flora metagenomics and
intestinal bacteria source
plasma exosome miRNA sequencing,
variable screening is carried out by adopting
LASSO regression and gradual backward regression, and finally, two miRNAs including miR1403p and miR10a5p and two intestinal strains including AnaliterunusspG32012 are obtained through screening. According to the
heart failure early-stage recognition method based on the Bifidobacteriumlonium, Bifidobacteriumlonium is used as a marker combination, meanwhile, a diagnosis model is constructed, high sensitivity and specificity are achieved for recognition of ventricular remodeling, the efficiency of early-stage recognition of
heart failure can be improved, ventricular remodeling can be better found, recognized and intervened as soon as possible,
heart failure can be better prevented and delayed, the heart failure early-stage recognition method can be applied to children, full-life-cycle screening and monitoring can be achieved, and the heart failure early-stage recognition method based on the Bifidobacteriumlonium can be used for early-stage recognition of heart failure. The method is expected to be applied to clinical examination and has clinical transformation value.
