Problems solved by technology

The commonly used clinical dialysis (including hemodialysis and peritoneal dialysis) and hemofiltration and other extracorporeal renal replacement therapy strategies can effectively remove small-molecule uremic toxins, as well as medium-molecule uremic toxins, but cannot remove protein-bound small-molecule uremic toxins.
Because whether it is the artificially synthesized semipermeable membrane used in hemodialysis and hemofiltration or the patient's own peritoneum used in peritoneal dialysis, it can only allow the free form of uremic toxin in the blood circulation to pass through, while the protein-bound uremic toxin is due to the free form. There is a small proportion, and the dialysis efficiency and filtration efficiency are very low

Abstract

The invention discloses application of danshinolic acid components in preparing pharmaceutical preparations for improving the dialysis rate and filtration rate of protein-bound uremic toxins. The danshinolic acid components include danshinolic acid B, protocatechuic aldehyde, rosmarinic acid, other danshinolic acid monomer components, pharmaceutical preparations containing salviae miltiorrhizae, pharmaceutical preparations containing salviae miltiorrhizae and safflower, and medicine suits with different salviae miltiorrhizae and safflower compatibility proportions. Through screening of a lot of experiments, results show that salviae miltiorrhizae and safflower injections and the danshinolic acid components can remarkably improve the dialysis efficiency of the protein-bound uremic toxins, can remarkably improve the filtering efficiency of the protein-bound uremic toxins, can be developed into auxiliary medicine preparations of in-vitro kidney replacement therapy strategies such as kidney disease dialysis and blood filtering, and have good development and application prospects.

Description

technical field [0001] The invention belongs to the technical field of medicines, and specifically relates to the application of salvianolic acid components in the preparation of preparations for improving the dialysis rate and filtration rate of protein-bound uremic toxins. Background technique [0002] The renal function of patients with end-stage renal disease is severely impaired, and the metabolic waste in the body cannot be effectively removed, resulting in the accumulation of more than 90 kinds of uremic toxins in the patient's body. Accumulated uremic toxins can induce complications such as bone disease, encephalopathy, cardiovascular disease, anemia, soft tissue calcification, and abnormal immune response. Reducing the level of uremic toxins in the patient's body can significantly improve the treatment outcome of patients with kidney disease. Uretoxins mainly include small molecule uretoxins (molecular weight <500Da), protein-bound small molecule uretoxins (mole...
