This study represents the first description of structural variations in the globin beta chains of 19 strains of inbred mice. The trypic pep tide mapping of beta chains of globin from BALB/c, BALB/cA, BALB/cJ, BALBcJ-nu, BALB/nu/ + ,BALB/cyJax,B10,B10A/sui,C57BL/6,C57BL/10snJ,SMMC/B,SMMC/C, C3H/He, CFW, DBA/2,SWI,Swars/nu/+,SSB and 129/sv strains of mice was established. The results showed that the position of peptide spots upon fingerprint mapping of beta chains was obviously different in comparison with each other. The different patterns of variability and polymorphism found in the various mouse species may then have come into being as a consequence of the action of selective forces on the various new beta chains which were created by some exchange processes.

OBJECTIVE:To provide reference for the selection of new edition of Essential Medicine List by quantitative com-prehensive evaluation for additional essential medicine. METHODS:The evaluation factors were established according to Delphi method,and Analytic Hierarchy Process(AHP)was conducted to compare the factors in pairs,construct the judgment matrix,cal-culate the weight coefficients of every factor and do the consistency test. RESULTS:The evaluation model was composed of 6 first-class indexes(including effectiveness,safety,stability,availability,affordability and adaptability)and 24 second-class index-es,and the weight of each index to the target layer was calculated. Among them,the weight of validity and security is the top two. CONCLUSIONS:The weight coefficient can be determined scientifically and reasonably by AHP,and the reliability and operability of the evaluation index system can be improved. It is a useful attempt to explore the selection system of additional essential medi-cine.

Objective To evaluate the value and significance of bedside ultrasound in diagnosis of lung atelectasis/consolidation in multiple trauma patients with mechanical ventilation.Methods Bedside thoracic ultrasound and chest computed tomography(CT)were performed in 81 multiple trauma patients with mechanical ventilation admitted to the emergency intensive care unit(EICU).CT result was regarded as the "golden standard" to evaluate the value of ultrasound in diagnose lung atelectasis/consolidation.At the same time,the ultrasound was used to dynamically monitor the lung recruitment effect of the therapeutic measures.Results CT detected 154 regions of lung atelectasis/consolidation of 324 lung regions in 81 patients,while ultrasound detected 126 regions that were divided into 87 complete regions and 39 incomplete regions according to different sonogram in the breathing cycle.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of ultrasound were 81.8%,100%,100%,85.9% and 91.4% respectively.A concordance test showed a very high concordance between ultrasound and CT,with a Kappa coefficient of 0.825(P=0.031).Ultrasound found that 39 regions with incomplete lung atelectasis/consolidation were completely recruited and 62 out of 87 regions with complete lung atelectnsis/eonsolidatian gained visible recruitment within three days after different therapeutic measures,with total effective rate of 80.2%.Conclusion Bedside ultrasound can continuously monitor and guide the therapeutic measure to recruit the lung and is a convenient,safe,direct-viewing and accurate method for diagnosis of lung atelectasis/cansolidation in multiple trauma patients with mechanical ventilation.
