发布时间:2018-11-18 07:34
【摘要】:目的探索白假丝酵母菌总RNA简单、快捷、高效的提取方法。方法选取昆明医科大学第一附属医院妇产科门诊2011年7月—2013年3月有临床症状且阴道分泌物镜检阳性的外阴阴道假丝酵母菌病(VVC)患者的白假丝酵母菌40株,选用不同时间与温度组合下的4种溶壁酶(Lyticase)破壁方案(A方案:37℃、12 h,B方案:25℃、12 h,C方案:37℃、24 h,D方案:25℃、24 h)进行RNA提取,将所得RNA进行荧光定量PCR(q PCR)反应验证RNA的浓度及纯度,并进行管家基因18S rRNA的检测。结果 D方案提取获得的RNA浓度高于A、B、C方案(P0.05);B方案提取获得的RNA浓度高于A、C方案(P0.05);而A、C两方案提取获得的RNA浓度比较,差异无统计学意义(P0.05)。B、D方案获得的RNA纯度高于A、C方案(P0.05);但A、C方案获得的RNA纯度比较,差异无统计学意义(P0.05);B方案提取获得的RNA纯度高于D方案(P0.05)。A、B、C、D方案提取的RNA扩增产物Ct转化值比较,差异有统计学意义(P0.05);其中B、D方案q PCR扩增产物Ct转化值高于A、C方案(P0.05);但B、D方案及A、C方案之间的q PCR扩增产物Ct转化值比较,差异无统计学意义(P0.05)。管家基因18S rRNA的引物扩增出的产物片段大小为150 bp。结论以Lyticase破壁提取白假丝酵母菌具有简单易行及RNA产量高、纯度好的优点,值得临床推广应用。
