Abstract: A helper epitope peptide is obtained by means of replacing one or two amino acid residues in the helper T cell epitope PADRE with 4-nitrophenylalanine. The helper epitope peptide is effective for enhancing the immunogenicity of an antigen or antigenic epitope or for preparing or constructing a vaccine, and a fusion antigen formed by connecting the helper epitope peptide to an antigen or an antigenic epitope.

Abstract: A pure bamboo fiber mattress and a manufacturing method thereof are disclosed. The manufacturing method includes the following steps: trimming and cleaning bamboo; sawing; splitting; slicing the bamboo strips; knitting; softening; directional fiber opening; dry cleaning, drying and removing dust; stacking; sewing and packing. The pure bamboo fiber mattress includes a surface layer, a transition layer, a core layer, another transition layer and another surface layer that are arranged in sequence from top to bottom. The surface layer includes 3-5 layers of first bamboo mesh fabric laid one on top of another. The transition layer includes 3-8 layers of second bamboo mesh fabric laid one on top of another. The core layer includes 3-8 layers of third bamboo mesh fabric laid one on top of another. The first bamboo mesh fabric, the second bamboo mesh fabric and the third bamboo mesh fabric are made of bamboo fibers.

Abstract: An apparatus for delaminating a bamboo into fibers includes a machine frame, a machine seat arranged in a middle of the machine, a machine cover matching with the machine seat, a push plate, a power source, and an elastic member. The machine seat includes multiple grooves formed in a top to respectively receive therein bamboo pieces. The machine cover includes multiple ribs formed on a bottom thereof. The machine cover is slidable relative to the machine seat to have the ribs of the machine cover respectively receivable in and engageable with the grooves of the machine seat so as to sandwich bamboo pieces therebetween. A push plate is driven by the power source to selectively move relative to the machine seat and has a bent end portion that bends and pushes portions of the bamboo pieces to slide on the top of the machine cover.

Abstract: Provided is a kind of modified recombinant human endostatin that has the structure of CH3O—(CH2CH2O)m—CH2CH2CH2—N?H-Endostar, wherein the average molecular weight of CH3O—(CH2CH2O)m—CH2CH2CH2— is 20-40 kD. The modified recombinant human endostatin enhances the stability in vivo, improves blood drug concentration, prolongs half-life, markedly increases the activity of inhibiting the endothelial cells proliferation, thus reduces drug dosage and decreases administration frequency. Its application for preparing anti-tumor pharmaceutical compositions is also provided.
