Stool samples were collected from patients with urolithiasis and healthy patients between March and December 2017. The samples were analyzed by 16S sequencing to determine differences in the microbiome profiles between the two groups. The mouse model was established and was divided into two groups. Fecal samples were collected from the mice before gavage and three weeks postgavage for microbiome analysis. The microbial population of each group was analyzed to screen for microbial species that may affect the formation of urinary stones. Differences in the number of crystals in the renal tubules of the mice were examined by necropsy. The microbial composition was different between urolithiasis patients and healthy controls. #link# The urolithiasis patients had significantly reduced microbial abundance; however, increased proportions of Bacteroidetes and Actinob in the mouse model of urolithiasis.As an acidic, ocean colloid polysaccharide, alginate is both a biopolymer and a polyelectrolyte that is considered to be biocompatible, nontoxic, nonimmunogenic, and biodegradable. A significant number of studies have confirmed the potential use of alginate-based platforms as effective vehicles for drug delivery for cancer-targeted treatment. In this review, the focus is on the formation of alginate-based cancer-targeted delivery systems. Specifically, some general chemical and physical properties of alginate and different types of alginate-based delivery systems are discussed, and various kinds of alginate-based carriers are introduced. Finally, recent innovative strategies to functionalize alginate-based vehicles for cancer targeting are described to highlight research towards the optimization of alginate. Acute myocardial infarction (AMI) is regarded as an urgent clinical
