RESUMO

Objective: To analyze the current status and problems in the process of transfer and transformation of health science and technology achievements, and propose countermeasures. Methods: A total of four universities, two research institutes, two medical institutions, two biomedical innovation enterprises and two biomedical industrial clusters were selected as the research subjects using the purposive sampling method. Field investigations and qualitative interviews were conducted. Additionally, relevant literature was reviewed to analyze the progress, achievements, main experiences, and problems in the process of health science and technology achievement transfer and transformation in China. Results: The policy for transformation of health science and technology achievements in China is gradually improving. There is a steady growth in investment in scientific and technological innovation, leading to continuous emergence of transformative achievements. The innovative entities are growing, and the service system for achievement transformation is being established with expanding capital support. However, challenges persist, including the lack of an effective evaluation system to promote achievement transformation, shortages of specialized service organizations and talents for transformation, unclear guideline for the transformation and industrialization of scientific and technological outcome, insufficient innovation research and development institutes in biomedical, and imperfection in the mechanism for transforming scientific and technological program achievements. Conclusion: Although great progress has been made in the transformation of health science and technology achievements in China, the quality and quantity of achievement still need to be improved. It is urgent to establish and implement an evaluation system for achievements transformation, accomplish the construction of specialized service institutions and the training of versatile talents for transformation, highlight the market-oriented mechanism for scientific and technological achievements transformation, explore system and mechanism reform, establish the mechanism for transforming scientific and technological program achievements in a faster pace, and optimize the policy, so as to promote the high-quality transfer and transformation of health science and technology achievements.

RESUMO

Lactoferrin in milk is a multifunctional protein. In addition, lactoferrin has antiviral, antifungal and antiparasitic activity. In this study, the N-terminus from porcine lactoferrin (PLF-N) was designed to express the antimicrobial action of recombinant porcine lactoferrin. We cloned a 1077 bp fragment of the PLF gene from mammary gland tissue of the lactating sow at the third day. Comparing nucleotide sequence with four strains of PLF gene published on GenBank, the homology was more than 99%. With the reference template of the cloned fragment of PLF-N and optimizing codon bias, we synthesized the gene of N-terminus encoding porcine lactoferrin (PLF-NS). The high expression gene of PLF-NS was cloned into the fusion expression vector pET30b and expressed in E. coli BL21 (DE3). After induced with Isopropyl beta-D-1-Thiogalactopyranoside (IPTG), the target fusion protein was successfully expressed and identified in inclusion bodies by SDS-PAGE and Western blotting. The protein had a molecular weight of 42 kDa and accounted for 32% of the total cellular protein. After purification and renaturation, the purity of the expressed protein was 98%. The expressed PLF-NS protein showed obviously antibacterial activity. This method provides an excellent way for high expression of antimicrobial proteins when optimizing codon bias.
