Abstract: A display panel, including: a base substrate including an Under Display Camera (UDC) area and a normal display area located around a periphery of the UDC area, and specifically, the normal display area includes a plurality of sub-pixel driving circuits, and the UDC area includes a plurality of groups of sub-pixels, each of the plurality of groups of sub-pixels including at least two sub-pixels of a same color which have their anodes coupled to each other; and a plurality of first transparent wires, anodes in each group of sub-pixels coupled to a corresponding sub-pixel driving circuit among the plurality of sub-pixel driving circuits through a corresponding first transparent wire among the plurality of first transparent wires.

Abstract: The present invention discloses a catalytic hydrogenation method for carbon nine resin, comprising the following steps: 1) adding a Pt—W—Y/?-Al2O3 catalyst in the first half of a fixed bed, adding a Pd—Zr—Nd/?-Al2O3 catalyst in the second half of the fixed bed, and feeding hydrogen for reduction; and 2) catalytic hydrogenating the pretreated carbon nine resin in the fixed bed. In the present invention, different catalysts capable of reacting under the same catalytic conditions are added in the first and second halves of the fixed bed, and the two different catalysts play different roles, and can be active and complementary to each other under the same conditions. The synergistic effect of the two catalysts plays a good catalytic role. Moreover, the production process is simplified, and the production cost is saved.

Abstract: Provided is an exosome, which is secreted by a hybrid cell formed by antigen-presenting cells phagocytosing the cell nuclei of tumor cells. Using the strategy of macrophages phagocytosing the cell nuclei of tumor cells achieves endogenous expression of tumor antigens on macrophages, and the exosome prepared has good capabilities of targeting to lymph nodes and tumors dually.

Abstract: An exhaust gas post-treatment apparatus comprises a first mixing chamber assembly and a second mixing chamber assembly. The first mixing chamber assembly comprises a first housing provided with a first mixing chamber, a gas inlet pipe, a first mixing pipe at least partially located in the first mixing chamber and a perforated pipe located in the first mixing pipe. The first mixing pipe includes a first pipe body located in the first mixing chamber and a second pipe body extending from the first mixing chamber, wherein a side wall of the first pipe body is provided with apertures and flow plates located in the first mixing chamber. In the axial direction of the perforated pipe, the perforated area of the perforated pipe fully covers the length of the flow plates. The second mixing chamber assembly includes a flow-guiding hood.

Abstract: The present invention provides an electric oven, including a cooking cavity, wherein a plurality of upper heating tubes are installed at a top position in the cooking cavity, and a plurality of lower heating tubes are installed at a bottom position in the cooking cavity. The solution improves the arrangement structure of the heating tubes of the electric oven in that at least one of the upper heating tubes protrudes from the horizontal plane where the other upper heating tubes are located, and/or at least one of the lower heating tubes protrudes from the horizontal plane where the other lower heating tubes are located, such that the distribution of the heating tubes is more stereoscopic, and the distribution of heat generated by the heating tubes in the cooking cavity is more uniform, and accordingly the heating uniformity is improved.

Abstract: The present invention provides for the first time the identification of salivary protein and RNA factors that can be used in the detection of primary Sjögren's Syndrome. The present invention therefore provides methods of diagnosing and providing a prognosis for Sjögren's Syndrome, by examining relevant proteins (including certain autoantigens and autoantibodies) and RNA in a patient's saliva.

Abstract: A HBV mutation strain is provided, wherein rtE218G mutation occurs at the polymerase region of the mutation strain. The use of the HBV strain in screening anti-HBV drugs and related detection reagents used to detect rtE218G mutation are also provided.
