RESUMEN
Objective To developed A laboratory diagnosis of Moraxella catarrhalis by an laboratories diagnostic method real-time fluorescence quantitative PCR assay. Methods The specific primers and probes were designed based on the sequence of outer membrane protein CopB(copB)gene in Moraxella catarrhalis,and the Taqman probe RT-PCR method was developed to detect the Moraxella catarrhalis.The standard plasmids ex-tracted from the Moraxella catarrhalis standard strains were used to constitute the standard samples,and compared with these standard samples,the sensitivity of the fluorescence quantitative PCR assay was tested by the estab-lished standard curves.The specificity of the fluorescence quantitative PCR assay was tested by the DNA samples of other bacterias in the laboratory.Meanwhile,321 throat swab samples from inpatient and outpatient child pa-tients,with asthma infection were collected as clinical samples to validate the fluorescence quantitative PCR as-say.Results The standard curve was drawn in the real-time PCR by the Taqman fluorescence reporter.During the sensitivity tests,the newly-developed real-time fluorescence PCR could detect at least 10 copies of Moraxella catarrhalis,and could successfully distinguish several DNAs of the pathogens.On the basis of the validation result of the 321 throat swab samples,there are 25 Moraxella catarrhalis with 7.79 % positive rate.Conclusion The fluorescence quantitative PCR assay is of great sensitivity and specificity,and it can be widely used for the detec-tion of Moraxella catarrhalis.
RESUMEN
Objective To evaluate and screen the concentration and coordination degree of the opinions of the experts in TCM pediatrics on the preventive method of Practice Guidelines to Prevent Disease for Recurrent Respiratory Tract Infections in Children Prevented by Sachet-Therapy;To formulate scientific and practical methods for perfume pouch wearing in this book. Methods Delphi method was applied to this research. All questionnaires were designed based on the literature research and distributed to more than 30 experts for 3 rounds. And the results in the first two rounds of survey were analyzed. Results Totally 31 and 33 valid questionnaires were received in the first and second time respectively. The experts’ activity index was 88.6% and 93.4% respectively. The perfume pouch wearing methods of Practice Guidelines to Prevent Disease for Recurrent Respiratory Tract Infections in Children Prevented by Sachet-Therapy was set down. And most of the experts shared a positive view on the concentration and coordination degree of this book. Conclusion The experts’ opinions upon this draft are quite positive. The experts are from all over China, and they are quite professional, with representativeness. The perfume pouch wearing methods of Practice Guidelines to Prevent Disease for Recurrent Respiratory Tract Infections in Children Prevented by Sachet-Therapy are generally recognized by the experts. However, there are still some different ideas in terms of some indexes, which need to be further discussed.
RESUMEN
Although it has been widely used clinically,Chaihu Guizhi decoction was seldom reported being used to treat infantile diseases.In the recent years.more and more children have been caught by Recurrent Respiratory Tract Infections(RRTI),Chaihu Guizhi decoction should be paid attention for its good effects in treating RRTI.This article summarized related reports on this subject.hoping to provide evidence for reasonable application of Chaihu Guizhi decoction in treating pediatrics diseases.
