Objective　To find out the appropriate bedbound period after Coronary Arteriography (CAG) in order to reduce the complications and uncomfort caused by prolonged Bedbound period and affected limb immobilization.Methods　121 cases of CAG patients were randomly divided into the reduced period group (experiment group) and the conventional group (the control group),two ways of nursing and observation respectively.Result　the rate of complication occurred in the experiment group much less than that of in the control group and the bedbound period were different as well.The above items showed statistics significance (P<0.005～0.05).Conclusion　The reduced bedbound period decreases the suffering of CAG patients and provides the reliable clinical evidence for proper nursing approach in this field.

With the rapid development of modern science and technology,the post-genomics period has come with the complement of the sequence of body genome including several tens of human genome,the emphasis of life science transfer from instruction genome to the post-genomics period,functional genome.Proteomics is the most important part of it.The technology of proteomics is advanced day by day.Except the classical two dimensional gel electrophoresis,the technology of multi-dimensional liquid chromatography and the technology of isotope coded-affinity tags have been successively developed,as well as protein chip and phage display have been applied extensively.This article simply summarizes the key technologies of proteomics.

In order to obtain high yield of the HrpNEcc protein with a lower total cost,fermentation and lactose induction conditions for recombinant E.coli BL21(DE3)/pET30a(+)hrpN Ecc were optimized in flasks and the recombinant E.coli was fermentated in 7L fermenter.The optimized incoulum concentration was 5% and the optimized nutrient medium was TB medium.The HrpNEcc protein yield reached 417.60mg/L by adding 3g/L exogenous inducer lactose in the growth prophase of log-phase for the recombinant E.coli.The HrpNEcc protein yield was higher 36.73% than that of the case of no any inducer,and was higher 16.85% than that of the case of adding IPTG.The wet weight of cell pellet of the recombinant E.coli reached 57.24g/L after fermentation in 7L fermenter,the HrpNEcc protein reached 3.29g/L,about 50.2% of total cellular protein.
