The Location Algorithm of QRS Waves Based on Fractal Box Dimensions Detection Methods

We research fractal characteristics of ECG signal, and find that it is logarithmic linear relationship between the boxes number covering signal and box scale. It is shown that ECG signal have some characteristics. Further more, we discover that fractal dimensions at QRS site are higher than others when using a time windows to detect signal. Based on this foundation, we raise a location algorithm of QRS waves which is based on fractal boxes dimension detection methods. The application results of this algorithm show that it can get rid of noise in ECG effectively with high speed, so this algorithm can be used in real time detection of ECG signal.

Insulin induced LPL mRNA expression in THP-1 macrophage and acceleration of transferring the macrophage to foam cell

AIM:To investigate the effect of insulin on ox-LDL transferring the THP-1 cells to foam cells and influencing the LPL mRNA expression in THP-1 cells.METHODS:THP-1 cells were incubated with 50 mg/Lox-LDL and insulin at concentrations of 10 mU/L, 100 mU/L, 1 000 mU/L and 10 000 mU/L, respectively. The expression of LPL mRNA in cells was detected by RT-PCR. Lipoprotein lipase of THP-1 cells was presented by no-specific lipase staining. THP-1 cells were stained with oil red O. Accumulation of total cholesterol (TC) in THP-1 cells was determined with oxidase assay.RESULTS:In 100 mU/L、1 000 mU/L、10 000 mU/L insulin groups, LPL mRNA expression increased 2 times, the average cell perilength was longer, the percentage of positive oil red O staining cells was significant higher, the content of cholesterol in THP-1 cells was higher than in ox-LDL control (P＜0.05).CONCLUSION:Insulin accelerates transferring of THP-1 cells to foam cell with exposed to ox-LDL because LPL mRNA expression increased in the cells.
