Abstract: A molecular marker for diagnosing primary biliary cholangitis and a method for detecting same are provided. The anti-human multimer immunoglobulin receptor antibody is adopted as the primary biliary cholangitis diagnosis molecular marker so as to prepare the diagnosis reagent; the human multimer immunoglobulin receptor antibody is remarkably increased in serum of PBC AMA-M2 subtype positive and negative patients, which indicates that in the attack of PBC, the serum anti-human multimer immunoglobulin receptor antibody specifically targets human multimer immunoglobulin receptors on small and medium bile ducts in the liver, thereby causing damage to the small and medium bile ducts.

Abstract: The present invention relates to the field of fluid heat transfer, and discloses a heat transfer enhancement pipe as well as a cracking furnace and an atmospheric and vacuum heating furnace including the same. The heat transfer enhancement pipe (1) includes a pipe body (10) of tubular shape having an inlet (100) for entering of a fluid and an outlet (101) for said fluid to flow out; internal wall of the pipe body (10) is provided with a fin (11) protruding towards interior of the pipe body (10), the fin (11) spirally extends in an axial direction of the pipe body (10), wherein a height of the fin (11) gradually increases from one end in at least a part extension of the fin. The heat transfer enhancement pipe can reduce thermal stress of itself, thereby increasing service life of the heat transfer enhancement pipe.

Abstract: The present invention relates to the field of lamp technologies, and in particular to a lamp with improved lamp socket structure. The lamp includes an inner lamp socket which is connected to the first conducting wire and is made of rubber. A conductive terminal group is set inside the inner lamp socket. An integrally formed outer lamp socket is nested outside the inner lamp socket. A conducting wire hole is set in the outer lamp socket. An opening is set in the outer lamp socket. The lamp features the following advantages: 1, a metal socket is not necessary to be set, so that production cost is effectively reduced; 2, a vertical conducting wire is set, so that the lamp can be freely adjusted, with high flexibility and better decorative effect; and 3, with an indirect structure, the lamp enjoys a pleasant appearance.
