摘要 目的深入了解中国结核杆菌利福平耐药株rpoB基因531、526、516三个高突变率发生位点的碱基突变特点,为全面理解结核杆菌利福平耐药机制提供科学依据。方法计算机检索PubMed数据库,对截止2015年3月31日发表的中国结核杆菌利福平耐药株rpoB基因突变研究的文献数据进行整合分析。结果纳入分析文献49篇,获得3 319株利福平耐药结核杆菌rpoB基因各位点碱基突变的详细信息,其中257株(7.74%)未检测到突变、3 062株(92.26%)检测到rpoB基因突变。在3 062株rpoB基因突变株中:531、526、516位点突变的发生率分别为54.44%(1 667/3 062)、27.07%(829/3 062)和8.92%(273/3 062);531位点碱基突变以TCG/TTG突变为主,占93.58%(1 560/1 667);526位点碱基突变主要有CAC/GAC、CAC/TAC、CAC/CGC、CAC/CTC、CAC/AAC等类型,分别占33.53%(278/829)、26.30%(218/829)、13.27%(110/829)、10.13%(84/829)、8.08%(67/829);516位点碱基突变主要有GAC/GGC、GAC/GTC、GAC/TAC等类型,分别占35.53%(97/273)、35.53%(97/273)、16.85%(46/273)。结论中国结核杆菌利福平耐药株rpoB基因531、526、516位点碱基突变以单碱基突变为主,突变率最高的531位点碱基突变主类型较为单一,而526、516位碱基突变主类型则相对分散。
