Objective To explore the adeB gene expression level impact of tigecycline for multidrug resistance Acinetobacter baumannii.Methods 57 strains multidrug resistance Acinetobacter baumannii were separated from September.2012 to September.2014.Epsilome test method was used to detect minimum inhibitory concentration of tigecycline against multi drug resistant Acinetobacter baumannii.PCR amplification detected adeB, adeR, adeS efflux pump gene distribution.Real-time fluorescent RT-PCR detection technology were used to detect relative expression level of each gene. Results 57 strains of multidrug-resistant Acinetobacter Bauman MIC value were 0.1-8μg/mL.The calculation of MIC50 =2μg/mL, MIC90 =4μg/mL. 49 strains sensitivity accounted for 86.0%, 5 intermediate strains accounted for 8.8%, 3 resistant strains accounted for 5.2%.57 strains of bacteria were divided into 38 strains lower sensitivity group and 19 strains sensitive group, with reduced susceptibility in lower sensitivity group 30 strains, accounting for 78.9%, sensitive group were all sensitive to tigecycline, accounting for 100%, for tigecycline susceptibility sensitive group was significantly higher than that of lower sensitivity group ( P <0.65 ) .41 strains were detected adeB, adeR, adeS gene in all strains, accounted for 86.0%, 29 strains were detected adeB, adeR, adeS genes in lower sensitivity group, accounted for 70.7%,12 strains were detected in sensitive group accounted for 63.2%, the difference between the two groups had no statistical significance.Fluorescent RT-PCR detection results showed that the relative expression of adeB gene with lower susceptibility group was significantly lower than that of sensitive group (P<0.05), relative expression levels of adeR and adeS gene in two groups had no significant difference.Conclusion AdeB gene plays an important role in tigecycline for multidrug resistance Acinetobacter baumannii, but may also exist outside of the adeB gene is involved in the regulation of resistance to tigecycline.
3.Gene polymorphisms predict efficacy and toxicity of chemotherapy for colorectal cancer
Tumor 2010;(2):164-169
Objective:The efficacy and toxicity of anticancer drugs differ in different tumor patients. It could not meet the requirements of optimization of tumor treatment if only under the guidance of clinical and pathologic characteristics. More and more attention is focused on individualized therapy based on individual gene profiles. It has been identified that gene polymorphisms are responsible for different outcomes of individuals. Gene polymorphisms, including sequence polymorphism and single nucleotide polymorphism, will decrease the clinical efficacy of chemotherapeutic drugs or increase adverse reactions by influencing the expression or activity of the corresponding proteins. In recent years several gene polymorphisms related to drug metabolism, transportation, or inactivation may affect the outcomes of chemotherapy and the frequency of adverse reactions. Identification of the polymorphism genes is important for individual therapy for tumor patients.
