SUMMARY Trauma is a global social problem, with the number of deaths up to 5.8 million all over the world annually.Currently, severe trauma has become the first cause of death in young adults in China. Nowadays, there are many problems in the trauma rescue system, including long pre-hospital transfer pe-riod , several secondary transfers, no information exchange between pre-hospital and in-hospital care, and the poor integrated treatment, which results in the situation that the overall treatment level of severe trau -ma in China is relatively low.In order to solve these problems, we carried out the research and promotion of severe trauma rescue standard, involving completing severe trauma information database , providing lo-cal rescue medical workers with standard training , and building up the information system for the linkage and warning of severe trauma.In addition, we developed and promoted the new standard system for se -vere trauma in 15cities with 124 medical centers.Due to our research, the treatment ability of severe trauma in the pilot areas was enhanced, and the mortality and morbidity of severe trauma were reduced significantly.To sum up, we had got the expected results after implementing the project .

Objective To subclone express and identify the immune mapped protein 1 IMP1 which encodes a surface an?tigen of Toxoplasma gondii. Methods The cDNA of T. gondii RH strain was synthesized by reverse transcription PCR the IMP1 open reading frame ORF was amplified by PCR using the T. gondii RH strain cDNA as template the PCR products were identified by TA?cloning and sequencing then the IMP1 ORF was subcloned into the NdeⅠand Xho I sites of the vector pET28b and the positive recombinant pET28b?IMP1 was identified by double?digesting and sequencing. The protein of 6 × His tagged IMP1 was inducibly expressed in E. coli strain BL21 DE3 with isopropylβ?D?1?thiogalactopyranoside IPTG and the induction time concentration of IPTG and temperature gradients to optimize protein expression conditions were determined. After the cells carried IMP1 were induced by the optimized conditions and harvested the resulting bacteria were suspended in resuspension buffer and lysed by sonication and the supernatants were loaded onto the Ni2+Chelating Sepharose Fast Flow col?umn for affinity chromatography of the N?terminal 6 × His tagged IMP1 protein. Finally the fusion IMP1 proteins were identified by Western blotting. Results The ORF sequence of IMP1 was successfully subcloned from the cDNA of Toxoplasma Gondii RH strain and the amplified product was sequenced and identified based on which the IMP1 ORF gene was inserted into the prokaryotic expression vector pET28b and the recombinant pET28b?IMP1 was constructed successfully. The double?digesting and sequencing results indicated the validity of the recombinant vector. And the optimized conditions for the expression of IMP 1 was determined namely 0.3 mmol/L IPTG induction for 9 h at 20℃. Furthermore IMP1 protein was expressed solubly and che?lated on Ni2+sepharose beads with high affinity thus this protein could be purified efficiently by affinity chromatography. The pure fusion protein was confirmed with fine immunocompetence by SDS?PAGE and Western blotting. Conclusions IMP1 pro? tein can be high efficiently expressed by the E. coli prokaryotic expression systems the protein of IMP1 is soluble and has stable characters. The study may lay a useful foundation for the following works including in vivo expression of IMP1 crystal structure study of IMP1 and anti?toxoplasmosis subunit vaccine development.

Metal-organic frameworks (MOFs) are mixed porous materials which are composed of metal clusters or ions and organic pillars. Given their channel tunability, high porosity, large specific surface area, and good biocompatibility, MOFs can be combined with various biological macromolecules. In recent years, they have been widely studied in the field of biomedicine, especially in the loading of anti-tumor drugs, showing great application prospects. Multifunctional anti-tumor MOF combined with different therapeutic methods provides a new idea and method for tumor treatment. On the basis of the structure of MOF, this paper introduces the advantages of using MOF to load anti-tumor drugs and reviews the application of MOF in tumor therapy.
