    • This invention relates to interfering RNA (iRNA) molecules and their applications, especially multi-targets iRNA molecules and their applications. The said multi-targets iRNA molecules comprised of a sense strand annealed onto at least one antisense strand, each strand is at least 30 nucleotides in length, the sense or antisense strand has at least two segments, which can target at least two RNAs of different genes, or can target at least two portions of an RNA, and wherein the iRNA does not induce an interferon-response when transfected into a cell. The iRNA molecule can interfere with the translation procedure post-transcription, and the target gene is inhibited or blocked, the iRNA does not induce an interferon-response in vivo. The RNA molecules are the active ingredient in preparation of the drug which can regulate one or many genes function.

    • The present invention discloses a large-field unit-magnification projection optical system. The optical system includes an optical axis, a spherical concave reflection mirror; a lens group with positive refracting power arranged adjacent the mirror with an air space therebetween. The lens group includes a first plano-convex lens, a negative meniscus lens adjacent the plano-convex lens, a positive lens adjacent the negative meniscus lens, a negative double-convex lens spaced apart far from the positive lens, and a second plano-convex lens. The optical system further includes a pair of prisms each having respective first and second surface. The second surfaces are arranged adjacent the flat surface of the plano-convex lens element on opposite sides of the optical axis and the first surfaces are arranged adjacent object planes and image planes, respectively. Each lens in the lens group and the pair of prisms provide chromatic aberration correction in a spectral region that contains at least g, h and i-line wavelengths. In this projection optical system, the object plane is parallel to the image plane.
