We collected the largest cohort of LUAD patients (n=3533) to date and analyzed the profiles of chromosome arm aneuploidy (CAA), and its association with different metastatic sites and mutated gene groups. Our results showed distant metastasis (bone, brain, liver) were characterized by high CAA burden and biased towards arm losses compared to regional metastasis (pleura, chest) and primary tumors. Moreover, EGFR, MET, PIK3CA, PKHD1 and RB1 mutant groups were found to have high CAA burden, while those with BRAF, ERBB2 and KRAS mutations belonged to the low CAA burden group. Comparing EGFR L858R and EGFR 19del mutants, distinct CAA co-occurrences were observed. Network-based stratification with population based genomic evolution analysis revealed two distinct subtypes of LUAD with different CAA signatures and unique CAA order of acquisition. In summary, our study presented a comprehensive characterization of arm aneuploidy landscape and evolutionary trajectories in lung adenocarcinoma, which could provide basis for both biological and clinical investigations in the future.Ischemic stroke is one of the leading causes of death and disability among adults. Despite the economic burden of the disease, available treatment options are still very limited. With the exception of anti-thrombolytics and hypothermia, current therapies fail to reduce neuronal injury, neurological deficits and mortality rates, suggesting that the development of novel and more effective therapies against ischemic stroke is urgent. In the present study, we found that artemether, which has been used in the clinic as an anti-malarial drug, was able to improve the neurological deficits, attenuate the infarction volume and the brain water content in a middle cerebra
