The invention discloses a portable folding bicycle, and belongs to the field of bicycle structural design. With the improvement of people's environmental awareness, more townspeople select a 'bus plus bicycle' trip mode. However, bicycles are not allowed to be brought on buses in main domestic cities currently, so that the conflict can be solved by folding the bicycles into luggage sizes and bagging the folded bicycles. Through application of two dead center positions of double rocker mechanisms, a folding bicycle frame with good mechanical properties and being flat in shape and convenient to bag and carry after being folded is designed. Coupling of six groups of pairwise symmetrical four-rod mechanisms enables the degree of freedom of the folded bicycle frame to be 1, so that the bicycle frame is convenient to fold. The bolt-type fixation is convenient and reliable. Through matching between an upper handlebar folding mechanism and a saddle folding mechanism, the size of a folded bicycle body is not greater than 830mm*630mm*280mm, and the bicycle can be packed into a luggage case or a portable knapsack with the above size. 16-inch wheels are adopted, accessories are all standard options, and the portable folding bicycle can be widely popularized.

The invention provides a construction and an application of recombinant human interleukin 12 eukaryotic expression vector and relates to the development of recombinant human interleukin 12 (rhIL-12) eukaryotic expression vector, the screening of stable expression cell lines and the adjuvant function of nucleic acid vaccine gene and the therapeutical effect of tumor gene. Ten hydrophobic flexible amino acid joints are used to connect P40 and P35 to obtain fusion gene to construct rhIL-12 eukaryotic expression plasmid (pCDNA6-IL-12), then the expression plasmid is transferred to CHO cell and finally stable expression cell lines are screened. The expression product has good biological activity. Nucleic acid vaccine and pCDNA6-IL-12 are used for coimmune so as to significantly increase the immune effect. Strong antitumor effect can be exerted when the expression vector of the invention is directly injected inside the tumor of laboratory mouse tumor model or is first used to perform gene modification to tumor cells and then implanted in tumor. The expression vector of the invention can be used in the search of clinical trial stage after further perfecting.

The invention belongs to the field of biological engineering, and in particular to recombinant expression and purification of a fifth functional domain of an oxLDL binding protein human serum beta 2-glycoprotein I and the application thereof to diagnosis prevention and treatment of atherosclerosis. A designed primers pair is subjected to PCR amplification on a T vector of a beta 2-GPI gene fragment to obtain a gene fragment of a beta 2-GPI fifth functional domain; and pPICZ alpha A-DV is constructed by cloning, and is then subjected to power transformation to obtain a positive strain, which is subjected to recombination and purification to obtain a P.r beta 2-GPI-DV protein. The possibility of using the recombinant protein as a drug in the prevention and treatment of atherosclerosis and the feasibility of detecting the oxLDL content in serum are proved. The P.r beta 2-GPI-DV recombinant protein has purity above 90%, can reduce the content of oxLDL / beta 2-GPI binary compound in the serum, and then inhibit the uptake of oxLDL by scavenger receptors on the surface of macrophage, so as to achieve the effect of preventing and treating atherosclerosis; and because of the combination specificity with oxLDL, the P.r beta2-GPI-DV can realize the specific detection of oxLDL in serum.
