Qualitative excretion profiles, limits of detection and extraction recoveries were established for furazadrol F and major confirmed metabolites. These investigations identify the key urinary metabolites of Furazadrol following oral administration, which can be incorporated into routine screening by anti-doping laboratories to aid the regulation of greyhound racing. Lung cancer is one of the most common malignant tumors threatening human health. The aim of this study was to investigate the function of miR-21-5p in lung cancer progression. We analyzed the expression levels of miR-21-5p in lung cancer tissues and cell lines. The qRT-PCR and MTT assays were performed after transfection with miR-21-5p mimic, inhibitor and negative control into lung cancer cells. Luciferase reporter assays showed miR-21-5p directly target SMAD7. The miR-21-5p inhibitor significantly suppressed lung cancer cell proliferation, invasion and migration. We found that SMAD7 was upregulated in lung cancer tissue. In addition, we found that SMAD7 inhibited lung cancer cell proliferation and miR-21-5p mimic damaged the inhibitory effect of SMAD7. miRNA-21-5p may promote cell proliferation, migration and invasion by spoiling SMAD7 expression in lung cancer cells. miRNA-21-5p may promote cell proliferation, migration and invasion by spoiling SMAD7 expression in lung cancer cells.Gasterophilus spp. have been found to be widespread in reintroduced Przewalski's horses in the Kalamaili Nature Reserve (Northwest China). However, data on the annual variation in Gasterophilus infections are lacking. To analyze the epidemiological features and determine the cause of the annual variation in Gasterophilus infections, we treated 110 Przewalski's horses with ivermectin and collected Gasterophilus larvae from fecal samples each winter from 20
