A total of 226 NDMM patients in our center were included in the study. The characteristics, survival, and adverse reactions were compared among patients who received maintenance therapy or not, and patients who received proteasome inhibitors (PIs) or immunomodulators (IMiDs) maintenance. The survival of different maintenance durations of bortezomib-based regimens was also analyzed. The maintenance therapy not only upgraded more patient responses (34.3 13.3%, = 0.006), but also significantly prolonged their progression-free survival (PFS) (median PFS 41.1 10.5 months, < 0.001) and overall survival (OS) (median OS not reached 38.6 months, < 0.001). Compared with IMiDs, the PFS (median PFS 43.7 38.5 months, = 0.034) and OS (median OS not reached 78.5 months, = 0.041) were both enhanced by PIs maintenance. Patients younger than 65 years whomaintenance with an increased OS. A bortezomib-based maintenance therapy duration of 12 to 24 months after induction and consolidation therapy produced satisfactory OS. PIs maintenance was superior to IMiDs in overall PFS and OS. The beneficial effect was most evident in patients achieving PR after induction and consolidation therapy, and in high-risk patients. Moreover, younger patients also benefited from PIs maintenance with an increased OS. A bortezomib-based maintenance therapy duration of 12 to 24 months after induction and consolidation therapy produced satisfactory OS.Species-specific lncRNAs significantly determine species-specific functions through various ways, such as epigenetic regulation. However, there has been no study focusing on the role of species-specific lncRNAs in other species yet. Here, we found that siRNAs targeting mouse-specific lncRNA AA388235 could significantly induce death of human tumor cells, although it has no effect on mouse tumor c
