The utility model relates to the field of audio and video display terminals, and discloses an audio and video display terminal which comprises a supporting frame, universal wheels are arranged on the lower surface of the supporting frame, a supporting plate is rotatably connected to the inner surface of the supporting frame, a display screen is arranged on the front surface of the supporting plate, a plug is connected to the bottom end of the display screen in an inserted mode, and the universal wheels are arranged on the lower surface of the supporting frame. A protection assembly is arranged on the lower surface of the supporting plate, and an adjusting assembly is arranged at the right end of the supporting frame. The protection assembly comprises a mounting plate, the mounting plate is fixedly connected to the lower surface of the supporting plate through bolts, and a fixing block is fixedly connected to the rear surface of the mounting plate. According to the utility model, the protection assembly can effectively protect the plug. The motor drives the screw rod to drive the positioning plate to move, and the sliding rod is extruded by using the special concave shape of the positioning plate, so that the protection plate sleeves the outer wall of the plug, thereby preventing the plug from falling off due to the fact that a pedestrian stumbles a data line by mistake, enhancing the stability of equipment in use, and guaranteeing the reliability of data transmission.

The invention provides a video display terminal related dry eye diagnostic biomarker and a therapeutic drug based on epithelial-mesenchymal transition and fibrosis. By studying functional transformation of epithelial cells in the VDT-related dry eye, epithelial-mesenchymal transition of ocular surface epithelial cells in the VDT-related dry eye is revealed, and fibroblast characteristics and proinflammatory characteristics are presented in an acute stage of a disease course, so that the acute stage and the chronic stage of the VDT-related dry eye are distinguished. Disclosed are biomarkers for diagnosing or monitoring the efficacy of a treatment for VDT-related dry eye, and preparation of reagents or kits for diagnosing, monitoring the efficacy of a treatment for a VDT-related dry eye, or differentiating acute and chronic progresses in VDT-related dry eye patients based on the markers. Besides, intervention aiming at the epithelial-mesenchymal transition and fibrosis process is an effective strategy for relieving VDT-related dry eye inflammation and improving ocular surface injury, and a potential intervention direction and prospect are provided for clinical treatment of VDT-related dry eye.

A computer server of an aircraft inflight entertainment system includes at least one network interface, at least one processor connected to communicate through the at least one network interface with VDUs, and at least one memory storing modules executable by the at least one processor. An entertainment module operates to distribute entertainment content through the at least one network interface for playout through the VDUs. A user announcement distribution module operates to distribute user announcements through the at least one network interface to the VDUs for playout as video on display devices and / or audio through audio interfaces. A scheduling module operates to selectively defer distribution of at least part of the user announcements through the at least one network interface to the VDUs based on at least one deferred announcement rule.
