This study aims to identify the resistance genes associated with erythromycin resistance and to determine the genetic relationships of IPD isolates in Chinese children. Methods A total of 171 S. pneumoniae strains were isolated from 11 medical centers in China from 2006 to 2008. All the isolates were characterized via serotyping and antibiotic susceptibility determination. The erythromycin-resistant isolates were further characterized via ermB and mefA gene detection, multi-locus sequence typing analysis, and pulsed-field gel electrophoresis. Results A total of 164 （95.9%） isolates showed resistance to erythremycin, of which 162 strains with high high-level resistance （MIC 〉 256 pg/ml）. A total of 104 （63.4%） isolates carry the ermB gene alone, whereas 59 （36.0%） harbor both ermB and mefA genes. Of the 59 strains, 54 were of serotypes 19A and 19F and were identified as highly clonal and related to the TaiwanlgF-14 clone. Conclusions The erythromycin resistance rate in IPD isolates is significantly high and is predominantly mediated by the ermB aene. Isolates that carrv both ermB and mefA Qenes are oredominantlv of serotvoes 19A and 19E展开更多
文摘目的评估维持性血液透析(maintenance hemodialysis,MHD)动静脉内瘘右利手患者的双侧上肢功能,了解动静脉内瘘对上肢功能的影响及内瘘侧上肢功能的影响因素。方法横断面研究,纳入北京市6家血液透析中心的MHD动静脉内瘘且右利手患者,收集人口学资料、生化资料、握力、关节活动度及简易上肢功能检查(simple test for evaluating hand function,STEF)等上肢功能指标。内瘘侧及非内瘘侧上肢功能的比较采用t检验(或非参数检验),采用多元线性回归分析MHD患者动静脉内瘘侧握力的影响因素。结果共入组MHD患者90例,其中男性51例(56.7%),年龄(59.63±10.60)岁,中位透析龄62.50(24.00,113.00)月。患者非内瘘侧握力高于内瘘侧握力(t=-5.133,P<0.001);多元线性回归结果显示MHD患者内瘘侧握力与血肌酐(β=0.353,P<0.001)、认知功能评分(β=0.223,P=0.006)呈正相关,与尿素清除指数(Kt/V)呈负相关(β=-0.235,P=0.007),男性握力大于女性(β=-0.253,P=0.004)。非内瘘侧腕关节尺偏的角度大于内瘘侧(t=-2.814,P=0.006)。在STEF各项操作中,内瘘侧在大球(t=2.327,P=0.021)、大圆片(t=2.472,P=0.015)、布(t=2.688,P=0.008)项目中操作时间长于无内瘘侧。结论MHD患者内瘘侧握力、关节活动度及灵活性均存在下降,影响内瘘侧握力的因素包括性别、血肌酐、Kt/V和认知功能评分。
