To determine whether PlncRNA-1 induces apoptosis in prostate cancer cells through the Her-2 pathway. The expression of PlncRNA-1, Her-2, and related cyclin proteins in 23 cases of prostate cancer and adjacent normal tissues was analyzed and compared. LNCaP cells were divided into a control group and an LNCaP-PlncRNA-I-siRNA experimental group. Normal prostate RWPE-1 cells were divided into an RWPE-1 control group and an RWPE-1-PlncRNA-1 experimental group. After PlncRNA-1 silencing and overexpression, changes in Her-2 and cyclinD1 expression levels were detected both in vivo and in vitro. In prostate cancer tissues, Her-2 and PIncRNA-1 were highly expressed and significantly correlated. In LNCaP cells, the expression of Her-2 and cyclinD1 decreased following the downregulation of PlncRNA-1 as assessed by real-time PCR and Western blotting. In RWPE-1 cells, the expression of Her-2 and cyclinD1 increased following PlncRNA-1 overexpression. Flow cytometry revealed that the proportion of LNCaP cells in G2/M phase was significantly increased after PlncRNA-1 silencing and that the proportion of RWPE-1 cells in G2/M phase was significantly decreased after PlncRNA-1 overexpression. Furthermore, animal experiments validated these results. In conclusion, in prostate cancer, PlncRNA-1 regulates the cell cycle and cyclinD1 levels and can also regulate proliferation and apoptosis in prostate cancer cells through the Her-2 pathway.

Flap side-edge noise is a significant noise source for airplane at takeoff and landing stages. The generation mechanism of flap side-edge noise is analyzed by numerical simulation on unsteady flow field using Very Large Eddy Simulation （VLES）. Two kinds of flap side-edge shape modifications are proposed, and their frequency spectrum and directivity of far-field noise are compared with the baseline configuration using permeable integral surface Ffowcs Williams and Hawkings （FW-H） acoustic analogy method to investigate their effects on noise reduction. Via the numerical simulation of flow field and acoustic field, it proves that the flap side-edge noise is broadband noise in nature. The different shapes of flap side-edge change the pattern of flow field, vortex structures and the development of vortex, thus having influences on noise source distributions and characteristics of far-field noise. The result shows that at the given 5° angle of attack, the proposed flap side-edge shape modifications can reduce the overall sound pressure level （OASPL） by 1 to 2 dB without decreasing the lift and drag aerodynamic performances.
