Objective To investigate the predicted value and clinical reference range of the FIV1 in the normal adults in Shanghai.Methods A survey in 521 healthy adults was carried out in Shanghai.FIV1 was measured by using Yager Master Screen difiusion(SN:694855).Explore the reference value and medical reference range.Analyse the relative on the FIV1 and age,weight,height in nomal adults.Results The lung functional parameter FIV1 have positive correlation with height and age,and the height and FIV1 realte closely.While,FIV1 is not related to the weight.The FIV1 predicted equation of normal adult males isFIV1--5.351+0.061 * height-0.027 * age (height,age,P <0.001,weight,P >0.05),medical reference range is 2.107 5 ~ 4.959 1.The FIV1 predicted equation of normal adult females is FIV1-2.457 + 0.04* height-0.025* age (height,age,P<0.001,weight,P>0.05),medical reference range is 1.278 3 ~ 3.517 1.Conclusions FIV1 is related to height and age.The Reference Values and Predicted Equation of normal adults is established and recommended in Shanghai area.
Objective To compare the selective power of anti-drug-resistant mutant of vancomycin , teicoplanin , linezolid and rifampicin to methicillin-resistant Staphylococcus aureus (MRSA) .Methods The minimum inhibitory concentration (MIC) to MRSA was determined by E-test method. Mutant prevention concentration (MPC) was measured by mix-bacterial method (the inoculated bacterial concentration1×1010CFU/mL) .Selection index (MPC/MIC) and the ratio of MPC to target maximum serum concentration (MPC/Cmax) of the four antibiotics were compared.Results MIC values of vancomycin , teicoplanin , linezolid and rifampin against MRSA were 0.5,1.0,0.5and≤0.5μg/mL; MPC values were 51.2, 25.6 , 9.6and 1024.0 μg/mL ; Selection indices were 102.4 , 25.6 , 19.2and2 048.0; MPC/Cmax were 1.28 , 0.57 , 0.64 and107.80 , respectively.Conclusion Linezolid and teicoplanin have narrower mutant selection window than vancomycin and rifampin , and they have obvious advantages in preventing bacterial antibiotic resistance.
