Lonicera japonica (L. japonica), a traditional Chinese herbal medicine, inhibits inflammation, but its role in neuroprotection is unclear. Polysaccharide is the main active ingredient in L. japonica. Here, we aimed to validate the effects of L. japonica polysaccharide (LJP) on lipopolysaccharide (LPS)-induced cognitive impairment and the underlying mechanism. The Chinese medicine system pharmacology database and analysis platform was used to predict the target of L. japonica; the GeneCards system was used to predict the AD target. We also performed Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Experiments were performed after bioinformatic analysis for verification. A chronic learning and memory impairment model was established by a single administration of LPS. Learning and memory abilities of Kunming mice were examined after 7 days of induction. The protective effeoved behavioral changes and neuronal loss associated with LPS-induced learning and memory impairments. The underlying mechanism may be related to the regulation of the autophagy pathways.Plasmapheresis, a procedure used to remove large molecular weight, protein-bound molecules from a patient's blood, has been shown to be useful in some cases of drug overdose. Levothyroxine sodium intoxication may result from the intentional or accidental ingestion of excessive amounts of the hormone, which can trigger a thyroid storm. However, case reports about the extremely large dose of 15,000 μg of thyroxine intoxication are extremely rare, and even combined with calcium channel blockers (CCBs) poisonings. We present a case of an intentional poisoning with high doses of thyroxine, diltiazem and amlodipine successfully treated with plasma exchange. A 40-year-old woman was admitted showing unconsciousness and sustained hypotension
