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.

Labour induced effect of misoprostol in comparing with oxytoxin on the ending 3rd trimestre of pregnancy was studied in 180 subjects at the Central Hospital of Gynecology and Obstetrics from January 1997 to January 2003. In 89.89% of misoprostol applicants and 67.78% of oxytoxine applicant success were reached. Labour induced meantime of misoprostol applicants 6.25  2.07 hours, oxitoxine 4.31  2.29 hours. Vaginal tract delivery in 88.3% of misoprostol applicant group and 70% of oxytoxine. Caesarian section 27.78% in misoprostol group, lower than oxytoxine group 44.44%.

Study on 70 patients with chronic inflamagingival at the age of 17-34 and 35-55. These patients have treatment with tooth-ointmently by ultra in the Institute No103, from October 2002 to October 2003. The results showed that: the cause of chronic inflamgingival was tooth-ointmently. In 2 studied groups, each patient have averagely 4 areas having tooth-ointmently, mainly inside of large molar tooth of lower jaw and outside of large molar tooth of upper jaw. The good results have achieved after one week and maintained after 3 months of treatment with tooth-ointmently by ultra combined with guiding dental hygiene. After 6 months, the good results have decreased highly. The patients need to take tooth-ointments again, to be guidlined and practised well dental hygiene

A theoretical study on eight extra channels includes: the Du channel, the Ren channel, the Chong channel, the Dai channel, the Yinwei channel, the Yangwei channel, the Yinqiao channel and Yangqiao channel. They doesn’t look like 12 main channels depend on viscera and there is no relation of internal-external. They tied closely with the extra-fu organs (the brain and uterus). A clinical application often use single point therapy, the application of stimulation at one point of the superficial of the body, the correlative leg-hand therapy to feel the point, the internal-external combining therapy, lower point for upper disease, upper point for lower disease, feeling right-left point, yin-yang co-point. Their application can be used in treatment for several conditions such as lose consciousness due to high fever, stroke, angina pectoris, cardiac arrhythmia, non-palpable pulse, hypertension and nervous depression

Some algorithms used in UV-Vis MCA spectrophotometry technique and some recent statistical approaches to the Advanced MCA technique were described. A number of pharmaceutical formulas containing 2-4 ingredients has been analyzed successfully using MCA technique. Basing on the basic algorithm of MCA and its statistical approaches, an applicable software for data processing had been established (running in Windows (environment - IBM compatible computer). This enables to use MCA technique for conventional spectrophotometers.
