ABSTRACT
Objective To assess the efficacy and safety of urinary kallidinogenase combined with sodium ozagrel for cerebral infarction (CI), and provide references for clinical rational drug use. Methods Retrieved from Cochrane library, PubMed, CBM, FMJS, VIP, Wangfang database and CNKI ( published until January 2015), randomized controlled trails (RCT)about urinary kallidinogenase combined with sodium ozagrel for treatment of CI were included,then methodological quality were evaluated and statistical analysis of those studies were carried out by Rev Man 5.3.4 software. Results 19 RCTs were included,involving 1 747 patients. Results of Meta-analysis showed that urinary kallidinogenase combined with sodium ozagrel could significantly improve total effective rate[RR= 1.18, 95%CI(1.13, 1.23), Z= 7.97, P<0.000 01], cure rate[RR = 1.42, 95%CI(1.23, 1.64), Z= 4.86, P<0.000 1], neurological deficit scores[MD= -4.40, 95%CI(-5.36, -3.43), Z= 8.90,P<0. 000 01] and activity of daily living scores[MD = 19.14, 95%CI(17.39, 20.90), Z = 21.36, P<0.000 01]. Conclusion Urinary kallidinogenase combined with sodium ozagrel was effective in the treatment of CI, and no significant adverse reactions were observed. The combination therapy was worthy of clinical application.
ABSTRACT
Objective To establish a specific,stable and reliable real-time fluorescence quantitative PCR for detecting plasma mi-croRNAs(miRNAs).Methods The plasma samples from 10 healthy individuals were collected,and miRNAs was extracted using mirVanaTM PARIS kit.Exogenous cel-miR-39 and cel-miR-238 and endogenous plasma miRNAs were reversely translated by spe-cific stem-loop primers and quantified by real time fluorescence quantitative PCR.Results cel-miR-39,cel-miR-238 and miR-342-3p were amplified and quantified specifically in RNA preparations isolated from plasma samples of healthy individuals.The amplifica-tion products of cel-miR-39,cel-miR-238 and miR-342-3p showed a single melting peak at 81.44,81.62 and 82.71 ℃,respectively, without primer dimer peak or non-specific peak in all 10 cases of healthy individual plasma samples.The standard deviation(SD)of intra-assay and extra-assay of miR-342-3p was 0.13-0.20,and the coefficient of variation(CV)was 0.42%-0.66%,which sug-gesting that this detection method has a good repeatability.The levels of miR-342-3p were detected in a same plasma sample,each experiment was repeated for 5 times,and normalized by cel-miR-39 and cel-miR-238.The SD and CV of ΔCt was 0.22,1.68%,re-spectively,which indicating that cel-miR-39 and cel-miR-238 could be taken as the stable exogenous reference for the plasma miR-NAs detection by real-time fluorescence quantitative PCR.Conclusion Real-time fluorescence quantitative PCR could serve as a good platform for plasma microRNA research.
