The diagnosis value of TNF-α ,IL-6 and NSE in cerebrospinal fluid of children with central nervous system infection / 国际检验医学杂志

Objective To explore the diagnostic value of tumor necrosis factor-alpha (TNF-α) , interleukin-6 (IL-6) and neuron enolase (NSE) in the cerebrospinal fluid of children with central nervous sys-tem infection (CNSI).Methods 54 cases of CNSI hospitalized children ,admitted in the hospital from October 2015 to January 2017 ,were enrolled in the study and divided into viral meningitis group (30 cases) and suppu-rative meningitis group (24 cases).Another 20 cases who underwent cerebrospinal fluid examination and other related examinations were enrolled in the study as the control group.The levels of three biomarkers TNF-α , IL-6 and NSE in cerebrospinal fluid of three groups were detected by enzyme linked immunosorbent assay (ELISA).Results The levels of TNF-α ,IL-6 and NSE in purulent meningitis group were the hightest ,and the levels of these three factors in viral meningitis group were highter than the control group ,and the differ-ence was statistically significant in three groups (P＜0.05).But there were a lot of data overlaps.There was no significant difference in the levels of TNF-α ,IL-6 and NSE between the brain group and the control group (P＞0.05).Conclusion The detection of TNF-α ,IL-6 and NSE in cerebrospinal fluid has a certain clinical val-ue for the diagnosis of CNSI ,but it needs to be further verified by a large sample clinical trial.

Characteristic and Analysis of Dynamic State Changes of Drug Resistance of Psedomonas Aeruginosa to Imipenem / 中国药房

OBJECTIVE:To investigate the change in drug resistance of pseudomonas aeruginosa to imipenem bewteen Jan.2000and Jun.2005in the hospital where the authors work in order to provide the reference for rational choice of antibac-terials in clinic.METHODS:158strains of imipenem resistant pseudomonas aeruginousa had been isolated in clinic and their drug sensitivity to antibacterials was tested by KB slip diffusion method and analyzed statistically.RESULTS:Meropenem,amikacin,and ceftazidime were among the antibacterials that kept high antibacterial activity and had resistance rates less than35%included.CONCLUSIONS:Imipenem resistant pseudomonas aeruginosa strain has stronger resistance to commonly used antibacterials and its multidrug resistance is more severe.Rational use of antibacterials can help to control and lessen the drug resistance of bacteria.
