2.Data quality in clinical trials: the role of blind review.
Acta Pharmaceutica Sinica 2015;50(11):1498-1501
Blind review is one of the most important milestones in clinical trials, which connects data management process to statistical analysis. During blind review, data quality should be reviewed and assessed on both data management and statistical aspects. The primary work of data managers in blind review is to ensure the accuracy of data before it is handed over to biostatistics group. Database auditing, listing data reviewing and reconciliation should become a good clinical data management practice. Statisticians, on the other hand, will focus on quality findings related to protocol deviations or protocol violations. To investigate the protocol deviations and/or violations and relevant impacts on data outcomes, it is important to provide the essential basis of data quality through the blind review, and to assess the reliability of study outcomes.

The acute and chronic respiratory tract inflammation models were made to investigate the effect and mechanism of sterol extracts from Begonia Sinensis Rhizome (BSR). The first model of acute lung injury was made with Kunming mice by inhaling cigarette smoke, then the mice were treated with different concentrations of BSR sterol extracts. Lung tissue morphology was detected by HE staining, TNF-alpha/MPO were detected by Elisa, and cPLA2 protein were, detected by Western blotting respectively. Results showed that in model group, lung sheet became real, alveolar space shrank or disappeared, alveolar septum was thickened, plenty of inflammatory cells were infiltrated, capillary blood vessels were congestive and the expression of TNF-α, MPO, cPLA2 increased; after administration, a small amount of inflammatory cells were infiltrated, alveolar septum became obvious, capillary congestion status was significantly relieved and the expression of TNF-α, MPO, cPLA2 decreased (P < 0.05). The second model of chronic respiratory tract inflammation in BALB/c mice with bronchial asthma was induced by OVA, then the mice were treated with different concentrations of BSR sterol extracts. Lung tissue morphology was detected by HE staining, indexes such as IL-4, IL-5, IL-13 were detected by Elisa, and the cPLA2 protein expression was detected by Western blotting respectively. Results showed that in model group, a lot of inflammatory cells around lung vessels and bronchi exuded, bronchial goblet cells proliferated and the expression of IL-4, IL-5, IL-13, cPLA2 increased; after administration, inflammatory and goblet cell hyperplasia reduced, the expression of IL-4, IL-5, IL-13, cPLA2 also decreased (P < 0.05). The above results showed BSR sterol extracts could resist against respiratory inflammation by inhibiting cPLA2 in a dose-dependent manner.
