[Effect of chronic enhanced external counterpulastion on gene expression profiles of arterial endothelial cells of pigs fed with high-cholesterol diet].

Objective: To investigate the effect of chronic enhanced external counterpulastion (EECP) on gene expression profiles of arterial endothelial cells (ECs) of pigs fed with high-cholesterol diet.

Methods: Eight male pigs were fed with high-cholesterol diet for 12 weeks to induce arteriosclerosis and subjected to EECP for accumulative 36 h (2 h every other day for 18 sessions). Another 8 pigs on cholesterol-enriched diet and 6 normally fed pigs served as the arteriosclerosis model group and normal control group, respectively, and the high-cholesterol diet was maintained until the end of EECP treatment.

[Establishment of a pig model of chronic ally enhanced external counterpulsation].

Objective: To establish a pig model of chronic external counterpulsation.

Methods: Twelve pigs were anaesthetized with sodium pentobarbital (< or =30 mg/kg.b.

[Effect of chronic enhanced external counterpulsation on arterial endothelial cells of porcine with hypercholesteremia].

Objective: To verify whether chronic enhanced external counterpulsation (EECP) may repair artery endothelial cells (ECs) damage resulted from hypercholesteremia in pigs.

Methods: EECP was performed for 36 hours in pigs with hypercholesteremia and the left descending artery (LDA) was isolated for scanning electron microscopy (SEM). The ECs were collected from the thoracic aorta and analyzed by proteomic technique.

[Study on the method of skin's spectral analysis and diagnosis].

A kind of systematic structure to test skin color with optic-fiber probe is introduced. The system can be used to measure skin's reflecting spectrum by using a grating instrument system and a linear CCD sensor. According to the color theory and skin's reflecting spectrum, the formulae for calculating skin's color tri-stimulus value and chromatic error and the identified area of diseased skin's color are given.
