ABSTRACT
According to the characteristics of short time and large amount of samples for out of hospital emergency nucleic acid detection, this study introduces an out of hospital emergency nucleic acid detection cloud platform system, which realizes the functions of rapid identification of the detected person and one-to-one correspondence with the samples, and real-time upload of the detection results to Zhejiang Government service network for quick viewing and statistics, so as to complete the task of national nucleic acid screening efficiently and accurately that we must provide information support.

The authors introduced the construction of the central monitoring system of bedside monitor in a hospital, and introduced its software and hardware design scheme and function in detail. The implementation of the system guaranteed the medical safety, reduced the workload of medical staff, improved the work efficiency, and had the characteristics of low cost and practicability.
ABSTRACT
Combined with the development requirements of hospital medical disposable materials management and hospital information management,introduced a novel medical disposable materials management pattern which base on the enterprise resource planning chain supply systems.By optimizing purchasing procedure,inventory management,precision financial management,to realize the integrated management of the medical consumable materials affairs and financial affairs.
ABSTRACT
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.

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.
ABSTRACT
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.
