fMRI functional connectivity analysis of anxiety disease patients based on spatiotemporal Lyapunov exponent method / 中国医疗器械杂志

Attempting to use nonlinear spatiotemporal Lyapunov exponent to characterize fMRI brain functional connectivity of anxiety disease patients, we adopted the methods of nonlinear spatiotemporal Lyapunov exponent and linear correlation coefficients to analyses fMRI datum of 11 anxiety disease patients and 11 healthy volunteers, respectively. The results show that there are significant normalized variance exponent (NVE) differences in Inferior Frontal Gyrus (rIFG) and Medial Frontal Gyrus (MFG) between the two groups (P<0.01). And correlation coefficients shows significant differences (P<0.05). The spatial-temporal Lyapunov exponent method had higher sensitivity than the correlation coefficient method in the characterization of functional connectivity; Anxiety disease patients have abnormal functional connectivity in rIFG and MFG during our experiment.

HRV signal analysis based on wavelet transform / 生物医学工程学杂志

In accordance with the character of heart rate variability(HRV) signal, we have divided HRV signal into 1/f fractal component and 1/f non-fractal component by use of wavelet transform. This division will be beneficial to the acqusition of the character of HRV signal as well as to the quantitative analysis of 1/f fractal component.

Measurements of Cardiac Output of a New Bileaflet Mechanical Heart Valve Prosthesis Made in China / 航天医学与医学工程

Objective To observe the cardiac output (CO) of animals and patients underwent valve replacement with Jiuling bileaflet mechanical valve prosthesis.Methods 1) animal experiments:COs of six sheep that underwent mitral valve replacement with 21 mm prosthesis were measured with open cardiac catheterization during operation.Echocardiography and open cardiac catheterization under dobutamine stress were performed in two sheep 30 months post operation.2) patient measurements:COs of 14 cases of aortic valve and 10 cases of mitral valve replacements were measured with open cardiac catheterization,and after 12 months,they were measured with echocardiography.Results 1)animal experiments:the mean CO of 6 sheep was 2.5 L/min during operation with catheterization,and it of two sheep 30 months post-implant was 3.0 L/min with echocardiography and 2.9 L/min with catheterization.2)patient measurements:the mean cardiac index of four patients with 21 mm valve replacement was (2.55?0.27) L/(min?m2) with means of catheterization,and was (2.84?0.13) L/(min?m2) with echocardiography after 12 months.Conclusion It is demonstrated that cardiac function of animals and patients return to normal after they underwent the valve replacement with new China-made heart valve prosthesis (Juling).The new heart valve prosthesis has excellent hemodynamic performance.
