[Studies on the changes of chemical constituent in Inula nervosa during the processing].

Objective: To research the changes of chemical constituent in Inula nervosa during the processing.

Method: Inula nervosa processed with different conditions was determined by HPLC,with acetonitrile--water as a mobile phase using gradient elution, and the detective wavelength was 280 nm. The emerging compounds 1 was extracted by 50% ethanol, isolated and purified using chromatography, and identified according to the physicochemical properties and spectral analysis.

[Effects of hepatocyte growth factor gene transfer in combination with echocardiographic destruction of microbubbles in a rat model of experimental myocardial infarction.].

Objective: To evaluate whether ultrasonic microbubble destruction (US/MB) could enhance the therapeutic effects of hepatocyte growth factor (HGF) gene transfer for acute myocardial infarction (MI).

Methods: MI was induced by left anterior descending artery ligation in male SD rats. Two to 4 hours thereafter, MI rats were randomly treated with tail vein infusing pc-DNA3.

[Evaluation on cardio-ankle vascular index derived from ultrasound].

Objective: The cardio-ankle vascular index (CAVI) could be obtained by measuring pulse wave velocity (PWV) and blood pressure (BP). This method is associated with various technical drawbacks. We evaluated the accuracy and usefulness of CAVI measured by ultrasound via detecting the aortic and ankle flow directly by ultrasonic probe.
