ABSTRACT
Objective To evaluate the therapeutic effect of acupuncture combined with rehabilitation training on children with cerebral palsy. Methods A total of 68 children with cerebral palsy who met the inclusion criteria were randomly divided into two groups, 34 in each group. The control group was treated with Bobath therapy combined with Vojta therapy for rehabilitation training, while the observation group was treated with acupuncture on the basis of the control group. Both groups were treated for 12 weeks. Modified Ashworth method was used to assess the muscular tension of lower limbs, the gross motor function scale was used to assess the gross motor function, and the Fugl-Meyer motor function evaluation method was used to evaluate the limb motor function of children. And the serum levels of vascular endothelial growth factor and creatine kinase brain isoenzyme (CK-BB) were detected by ELISA. Results After treatment, the muscle tension score (1.3 ± 0.3 vs. 1.7 ± 0.4, t=4.108) in the observation group was significantly lower than that in the control group, while the GMFM score (55.7 ± 13.7 vs. 37.8±11.4, t=5.881) significantly higher than that in the control group (P<0.01). The serum VEGF (145.67 ± 19.78 ng/L vs. 171.35 ± 22.54 ng/L, t=4.993) in the observation group were significantly lower than those of the control group (P<0.01). The levels of CK-BB (71.46 ± 17.62 U/L vs. 95.76 ± 19.65 U/L, t=5.368) in the observation group were significantly lower than those of the control group (P<0.01). The total effective rate was 94.1% (32/34) in the observation group and 73.5% (25/34) in the control group. There were significant differences between the two groups (χ2=5.314, P=0.021). Conclusions Acupuncture combined with rehabilitation training can improve the muscle tension and gross motor function of children with cerebral palsy, reduce the levels of VEGF and CK-BB in serum of children with cerebral palsy, and improve the clinical effect.
ABSTRACT
In order to meet the requirements of ultrasound bone density measurement, we designed a sofware based on Visual Studio C+ + 2008. The software includes interface design, acquisition and control, data processing and parameter extraction, data storage and printing. Excellent human-computer interface (HCI) will give users a convenient experience. Auto gain control (AGC) and digital filter can improve the precision effectively. In addition, we can observe waveform clearly in real time. By using USB communication, we can send control commands to the acquisition and get data effectively, which can shorten the measuring time. Then we calculated the speed of sound (SOS) and broadband ultrasound attenuation (BUA). Patients' information can be accessed by using XML document. Finally, the software offers printing function.

In order to meet the requirements of ultrasound bone density measurement, we proposed a software solution to improve the accuracy and speed of measurement of bone mineral density of the ultrasound bone densitometer. We used a high-speed USB interface chip FT232H, along with a high-speed AD converter chip to calculate speed of sound (SOS), broadband ultrasound attenuation (BUA ) and other bone density parameters in the PC software. This solution improved the accuracy of the measurement data, reduced the measurement time and increased the quality of the displayed image. It is well concluded that the new software can greatly improve the accuracy and transmission speed of bone density measurement data through a high-speed USB interface and a software data processing technology.

The development of a multi-parameter and low-power monitor is discussed in this paper. The monitor equips an AT91SAM9261 microprocessor as its main controller and contains multi-parameter signal collecting module, data storage module, human-computer interaction module, online communications module and printing module. The whole software system is based on the uC/OS-II equipped by uC/GUI, which is used to facilitate interface design. At the same time, for the convenience of data management, a YAFFS2 file system is transplanted. The monitor has the advantages of low consuming, low cost, real-time control and multi-functions.

Image mosaicing can solve the problem that only very limited field of view is available when highly magnifying lens is used in microscope imaging. This paper puts forward an equation of the system's influence to the grayscale distribution of the medical microscopic images, based on the analysis of the influence. Then, by the system equation and the accurate registration equation, the least-squares optimization error function can be formulated. By these equations, a set of transcendental equations is formed. We can estimate the system's influence on the gray-level of the images by singular-value decomposition (SVD), based on the equations set, and compensating for it. This permits image mosaicing seamlessly, without lowering the speed.

Traditional 3D ultrasound reconstruction system can just depict 3D anatomical structure, so it is very difficult to give an accurate assessment of the functionality of the heart. In this study, a dynamic 3D reconstruction method of tissue Doppler ultrasound heart images is set up based on the combination of 3D reconstruction and tissue Doppler imaging technique. Dynamic 3D acceleration field of heart movement is reconstructed to supply a new approach of accurate assessment of functionality of the heart. The key problem of vector interpolation and fusion imaging in the process of acceleration vector field reconstruction is solved. The 3D acceleration field of heart movement and anatomical structure is reconstructed separately from the original tissue Doppler acceleration images and showed in the same field. The experimental results testified that the 3D space relationship of acceleration and anatomical structure is correct and this method can supply more information for the assessment of heart functionality.

Image interpolation techniques were widely applied in medical imaging for image generation and post processing. Firstly, traditional interpolation methods were listed out in the details of shape-based interpolation and dynamic elastic registration interpolation. Secondly, the characteristics, development and problems in interpolation of rotary scanning ultrasonic cardiac images were analyzed. The relation between interpolation and registration was stated. The analysis indicated that excellent methods in rotary scanning interpolation should be registration-based methods. At last, several evaluation methods about images interpolation were discussed.
