Abstract: An arc-shaped display screen with double-curved surface includes an arc-shaped frame and a plurality of LED display unit boards. The plurality of LED display unit boards are mounted on an inner surface or an outer surface of the arc-shaped frame in a detachable manner, and surfaces of the plurality of LED display unit boards constitute the arc-shaped display screen with double-curved surface. The frame is formed by splicing a plurality of structural units, and adjacent structural units are fixedly connected to each other. Each of the LED display unit boards is electrically connected to an external circuit. The arc-shaped display screen with double-curved surface has a simple structure and low cost. Moreover, compared with the movie screens of the existing screens with single curved surface, the arc-shaped display screen with double-curved surface has wider viewing angle, ultra-high picture definition, and high-fidelity sound quality etc.

Abstract: The present invention is about a mycobacterium smegmatis vaccine, a split product of mycobacterium smegmatis. This vaccine has made good use of the adjuvant function of bacterial cellwall and antigenic specificity of tropina which can stimulate the production of cytokine and consists of many immunologically competent CpG fragments of bacteria DNA. Such vaccine is prepared by treating newly-cultured thalli with a physical quassation technique. This vaccine is capable of enhancing normal immune function against TB, promoting the recovery of normal immune function in TB patients with hypofunction, and depressing the immunological responses in TB patients with hyperfunction. It is especially effective in the prevention and treatment of MTB carriers.
