Objective To screen and identify the phage-display random 7 amino acid peptide specific to the systemic lupus erythematosus(SLE) and analyze its practical significance. Methods Using the phage random 7 peptide library screening, the SLE specific phage clones are obtained after binding with the mixture of sera from 30 SLE patients and 30 normal controls as ligand respectively. Then the Dot-ELISA is used to identify the SLE specific phage clones reactive to sera of the SLE patients and normal controls individually. Finally the identified phage-display random 7 amino acid peptides are sequenced and it's homology with the antigenic epitope of human being and other are also analyzed. Results Total 12 of the phage-display random 7 amino acid peptide are obtained by phage peptide library screening and the Dot-ELISA identification. Sequence analysis shows that the identified phage-display random 7 amino acid peptide epitope have homology with E. coli, Salmonella and human immunodeficiency virus, but not with that of human being. Conclusion SLE-specific peptides screened by phage random peptide library maybe used to diagnosis the SLE. Meanwhile, the antibodies in SLE patients which are combined with the Pathogen epitope, suggest that SLE maybe relate to pathogen infection.

At present , laboratory medicine has become one of the fastest growing subjects in the field of medicine.The development of laboratory medicine directly led to the improvement of diagnosis and the increase of test methods in clinic .The data of project applications and grants of the National Natural Science Foundation of China in the field of laboratory medicine from 2014 to 2017 were reviewed and summarized.The future prospect was also analyzed to provide references for related researchers in this field .

To summarize the projects granted by National Natural Science Foundation of China related to tumor biomarkers in laboratory medicine from 2010 to 2018. The projects are categorized and analyzed according to tumor classification, biochemical properties of biomarkers. What′s more, characters of granted projects of tumor biomarkers in recent 9 years are summarized and development trends are pointed out.

Regarding to the sharply increased applications and relatively lower rate of successful funding for major projects in the fields of Critical Care/Wounds and Injuries/Burns/Plastic Surgery from the National Natural Science Foundation of China in recent years, the author summarized the funded projects in this specific field from 2014 to 2018, discussed the characteristics and trends of these applications and grants, and summarized the hotspot issues and frontier researches so as to help the applicants in the future.
