ABSTRACT
The paper is focused on the clinical applications of Tanreqing injection after listing, detecting and analyzing the related blood indicators of patients with allergic reactions based on prospective, multi-center, large sample, registration-type clinical safety monitoring nested case-control study (NCCS) to explore the possible mechanisms of allergic reaction of Tanreqing injection, 3 006 patients cases used with Tanreqing injection were monitored, including 3 cases of adverse reactions and 2 cases of allergic reactions. Each patient of allergic reactions, according to the ratio of 1:4 matches four cases of not adverse reactions as a control group of patients, while 5 healthy and 5 cases of volunteers into the healthy group. We examined the correlation detection of cases of allergic reactions among groups such as T-IgE, IgA, IgG, C3, C4, IFN-g, IL-2, IL-4, IL-6, IL-10. Allergic reactions of Tanreqing injection may be mediated by IgE as type I based on existing research data. This results and conclusions will promote the justifiability and safety of clinical applications.

Tanreqing injection is suitable for early pneumonia, acute bronchitis, acute exacerbations of chronic, and upper respiratory tract infection which are classified with phlegm-heat obstructing lung syndrome of traditional Chinese medicine. To understand the clinical adaptation syndromes and medication characteristics of the post-market Tanreqing injection, the research team of the paper monitored the patients who are used with Tanreqing injection from September 2012 to October 2013 in four leader hospitals based on the method--prospective, multi-center, large sample, registration-type hospital centralized monitoring,and analyzes the general information, diagnostic information and medication characteristics of patients, in order to produce evidence for clinical practice and medication decisions and to establish the foundation of rational drug use.

The structures and catalytic properties of AuPd clusters supported on carbon nanotubes (CNTs) for H(2)O(2) synthesis have been investigated by means of density functional theory calculations. Firstly, the structures of AuPd clusters are strongly influenced by CNTs, in which the bottom layers are mainly composed of Pd and the top layers are a mix of Au and Pd due to the stronger binding of Pd than Au on CNTs. Especially, it is found that O(2) adsorption on the Pd/CNTs interfacial sites is much weaker than that on the only Pd sites, which is in contrast to transition metal oxide (for example TiO(2), Al(2)O(3), CeO(2)) supported metal clusters. Furthermore, Pd ensembles on the interfacial sites have far superior catalytic properties for H(2)O(2) formation than those away from CNT supports due to the changes in electronic structures caused by the CNTs. Therefore, our study provides a physical insight into the enhanced role of carbon supports in H(2)O(2) synthesis over supported AuPd catalysts.
