Abstract:
ObjectiveTo study the differences in expression profiles of peripheral blood specific serum micro RNA(miRNA) in the comparison between those before and after Baihu Renshen decoction combined with Fufang Xiebai capsules for treatment of patients with severe pneumonia.Methods 136 patients with severe pulmonary infection accompanied by heat-phlegmand sthenic-fu syndrome admitted in the Department of Respiratory Medicine of Kunshan First People's Hospital Affiliated to Jiangsu University from January 2012 to December 2013 were enrolled in the study. They were treated with basic treatment and Baihu Renshen decoction〔gypsum 30 g(broken, wrapped in cotton cloth, firstly put in water to be boiled), American ginseng 4 g, fritillaria 10 g, bupleurum chinense 10 g, skullcap 10 g, fried gardenia(pittosporm root) 10 g, forsythia 12 g, honeysuckle 10 g, spiderwort grass(dayflower) 15 g, prepared licorice root 4 g〕 combined with Fufang Xiebai capsules〔mainly composed of longstamen onion bulb(macrostem onion)12 g, melon wilt(fructus trichosanthis) 12 g, pinellia 10 g, coptis chinensis 3 g〕. The changes of serum miRNA expression profiles before and after treatment were analyzed by Solexa sequencing. The peripheral blood serum specific miRNAs were confirmed by real-time fluorescent quantitation-polymerase chain reaction(qRT-PCR). Before and after treatment, the receiver operating characteristic curve(ROC curve) of patients with severe pulmonary infection was drawn, and the ROC curve was used to analyze the sensitivity and specificity of serum miRNA to the efficacy of the combination therapy and evaluate its clinical value.Results Solexa sequencing suggested that 42 kinds of miRNA appear to have over 2-fold in difference in the comparison between profiles before and after Baihu Renshen decoction combined with Fufang Xiebai capsules treatment. Real-time qRT-PCR confirmed miR-146a, miR-125b and miR-155 expressions were significantly decreased over 10 fold, suggesting that they should be specific miRNAs. The area under the ROC curve(AUC) of miR-146a was 0.81,95% confidence interval(95%CI)=0.73 - 0.89,miR-125b AUC=0.77,95%CI=0.71 - 0.83 and miR-155 AUC=0.89, 95%CI=0.83 - 0.95. Then, through selected clinical truncated(cut off)value,the sensitivity and specificity of three kinds of serum miRNA were calculated: 63% and 87% of miR-146a, 53% and 73% of miR-125b and 56% and 83% of miR-155.ConclusionAddition of Baihu Renshen decoction combined with Fufang Xiebai capsules on the basic treatment can induce significant changes of peripheral blood serum miRNA expression profiles in patients with severe pneumonia, and miR-146a, miR-125b and miR-155 among miRNAs could be their specific changes.
