Objective:Explore the education content and method for the accompanying persons to enhance the capacity of taking care of patient .Methods:Life satisfaction index ( LSR-A) Scale and accompanying persons chaperone capability questionnaire are the tools of this research .This research trained the 45 accompanying persons care ability, and used before and after comparison .Results:Before the intervention , Most of the persons′life satis-faction levels was at a low level (41 persons′≤13), only 4 (8.9%) at a medium level.After the intervention, life satisfaction levels was improved (27 persons′≥14).Life sat!sfaction was improved (P<0.05).Chaperone capability situation was improved , for the P values in all the examination were <0 .05 .Conclusion:The manage-ment could strengthen the support for accompanying persons , could effectively improve their life satisfaction and im-prove their ability to accompany , thus improving the quality of patient care .The hospital should also consider the nursing ethical problems in accompanying persons education .

Matrix_assisted laser desorption ionization_time of flight tandem mass spectrometry ( MALDI_TOF/TOF MS) and electrospray ionization_quadrupole_time of flight mass spectrometry ( ESI_Q_TOF MS) were used to confirm the structure of cyclic lipopeptide daptomycin fastly. First, the relative molecular weight 1916. 7107 of daptomycin was measured by ESI with error 0. 0007. The sample’s doubly charged peak m/z 809. 848 was selected as precursor ion for ESI_MS/MS analysis, and the exocyclic amino acid sequence C9 H19 CO_Trp_Asn_Asp was successfully matched. Second, the experimental conditions of cleaving daptomycin by lithium hydroxide ( LiOH) were optimized and the ring_opened process was monitored by MALDI_TOF/TOF MS. After obtaining ring_opened product with purity of above 95%, the MS/MS measurements by MALDI and ESI were carried out. The b+and y+of ring_opened product were completely matched, which confirmed the amino acid sequence of daptomycin. Finally, ESI_MS/MS conditions of ring_opened product were further optimized to obtain more low mass fragment ions for analyzing the structure of fatty acid chain and the cleavage pattern of fat chain in mass spectrometry was proposed. The method was fast, convenient, accurate and reliable for identifying cyclic lipopeptide compounds.
