Realtime xCELLigence analysis (RTCA) is a new cell detection technology to continuously monitor, record and analyze a variety of information generated by cell activity. In drug research, it plays an important role in assessing myocardial toxicity and cell biological activity. Here, we first introduce the underlying mechanisms and characteristics of RTCA. Then we review the applications of RTCA in the research of myocardial toxicity and cell biological activity, to provides the fundamental baseline for understanding and exploiting RTCA. With the real-time, unlabeled, non-invasive, high throughput, and high accuracy features, RTCA not only promotes drug research and development, but also has a broad and good application prospect in other fields.

Using the full quadratic model in drug dissolution optimization, the authors built up the sustained release of diclofenac tablet formulation with hydrophilic matrix excipient. The sustained excipient releases xanthan gum which has good features such as controlling medical substance regularly, rubbing seed easily, covering tablet easily and compressed force with a little affect to the rate of medical substance release. This formulation can be applied in making up medicines with a wider scale. It is being tested its stability and evaluated its availability to apply in manufacture
