To investigate the “real world” effectiveness of Traditional Chinese Medicine (TCM) in patients with acute myocardial infarction suffering from diabetes mellitus (AMI+DM patients).

The travel time is an important measure for the quality of traffic. This paper discusses a few methods to measure or estimate the travel time in urban road networks. First of all, it is important to know that urban travel times display a large variation, so that the measurement of a single (average) travel time is not so meaningful. The travel time distribution is more relevant than the single value of the average. This distribution can be obtained from observations of travel times of individual vehicles, for instance by tracing probe vehicles with GPS. The distribution of travel time can also be measured by Bluetooth scanners that can recognize Bluetooth devices in a car. Travel time over a link can be estimated by comparing passing times at its beginning and end. Automated Number Plate Recognition cameras have a similar possibility to follow individual vehicles from point to point. In the study of travel time measured in urban areas, the quality of data from Bluetooth scanners appeared to be disappointing. The most important reason is that outliers cannot easily be eliminated. This is especially a problem in urban areas. Another reason is the uncertainty about the Bluetooth devices’ carriers. It is difficult to identify whether the Bluetooth device belongs to a car or bus passenger, a cyclist or a pedestrian. Probe vehicles with GPS are very well appropriate for the measurements of travel times in urban areas.

Abstract: Objective: To study the effect of ligustrazine injection (LI) on vascular endothelial cell of the patients with arteriosclerosis obliterans (ASO) and explore the new pathway of investigating effective vascular protective agents in Chinese medicinal herbs.Methods: Forty-six patients with ASO in the LI group treated by LI were observed, their circulating endothelial cells (CEC) were detected quantitatively before and after treatment. The results were compared with the CEC of 53 cases of healthy persons (control group) in the same period.Results: In the LI group, the immediate cure rate was 45. 7% (21 cases), markedly effective rate 36.9% (17 cases) and the effective rate 17.4% (8 cases). The CEC of patients before treatment was 4. 39 ± 1. 76/0. 9μl, which was significantly higher than that of the healthy persons (1. 53 ± 0. 42/0. 9μl). It could be reduced after treatment, along with the improvement of symptoms and signs, to 2.43 ± 0.87/0.9μl, P<0.01.Conclusion: LI in treating ASO not only displays extraordinary effect, but also has good effect in curing the damage of endothelial cells.
