ABSTRACT
Objective@#To study the correlation between the blood routine indicators and CD4+ T, CD8+ T lymphocytes in AIDS patients without antiviral treatment, and to find a simple, cheap and effective monitoring indicator.@*Methods@#A study of 333 AIDS patients without antiviral treatment was performed.The methods of regression analysis and other statistical methods were applied to research the correlation between WBC, W-SCC and CD4+ T, CD8+ T cell count among HIV/AIDS.@*Results@#The rate of routine blood abnormalities among 333 HIV/AIDS patients was very high, the main test indicators within the reference range only accounted for 30.63%.The proportion of late diagnosis infected with HIV among women was higher than that of males.Significant correlations were observed between CD4+ Tcell count and WBC, W-SCC, W-LCC, RBC, HGB, PLT(r=0.408, 0.541, 0.157, 0.337, 0.338, 0.166). The equation between W-SCC (x) and CD4+ cell count (y) was y=120.913x+ 90.339.@*Conclusion@#There is a strong correlation between CD4+ T lymphocyte count and lymphocyte count in AIDS patients without antiviral treatment.It can be used as an important indicator of immune status in patients with AIDS.At the same time, we should strengthen the propaganda of AIDS prevention, promote AIDS early detection, early treatment, and improve the quality of life of AIDS patients.
ABSTRACT
Objective To research a method for detecting metallo-β-lactamase(MBL)to provide the basis for rationally selecting antibacterial drugs in clinic.Methods A total of 104 strains of imipenem-resistant Acinetobacter baumanmii(IRAB)were collected. The MBL phenotype was detected by using the EDTA disk potentiation test and the detection results were compared with the PCR detection results of MBL.Results Among 104 strains of tested IRAB,21 strains were the MBL gene positive by using PCR;24 strains were the MBL gene positive by using the EDTA disk potentiation test.Compared with the PCR detection results,the sensi-tivity of the EDTA disk potentiation test was 95.2% and the specificity was 95.1%.Conclusion The EDTA disk potentiation test for detecting MBL of Acinetobacter baumanmii is simple,credible in the detection results and cheap in cost,which is suitable for the preliminary identification of the MBL-producing Acinetobacter baumanmii in the clinical microbiology laboratory of the primary hos-pitals.
