Objective To design LCD system based on MSP430 using LCD controller S1D13700. Methods MSP430's control bus adopted the communication mode of MSC-51 singlechips, and was connected with S1D13700 by 8-bit data bus. The address buses were linked by the modes of indirect address and direct address respectively. Results The design was used for displaying cardiac wave and its parameters in cardiac monitor successfully. Conclusion The S1D13700's driver program, accomplished with standard ANSI-C, is gifted with brilliant versatility, and thus can be used in the design of the portable device.

Objective To analyze the relationship between the distribution of visceral adipose and cardiovascular damage in the patients with metabolic syndrome. Methods 108 in-patients were categorized according to the diseases, they were suffering from into metabolic syndrome group (MS, 70 cases), essential hypertension group (EH, 22 cases), and type 2 diabetes mellitus group (T2DM, 16 cases). The areas of both visceral adipose (VA) and subcutaneous adipose (SA) were measured for all the three groups, and then VA/SA was calculated. The relationship of the above variables with left ventricular mass (LVM), LVM-index (LVMI) intima-medial thickness (IMT) of carotid artery, and myocardial ischemia was analysed. Results Compared with T2DM and EH groups, the area with VA was significantly larger in MS group (P

Objective To certify insuline resistance in nonobese patients with essential hypertension(EH) and observe effect of imidapril.Methods An oral glucose tolerance test(OGTT) and insulin releasing test(IRT) were performed on 40 nonobese EH patients before and after imidapril treatment,the plasma levels of glucose and insulin were tested and compared with those of 16 normal subjects.Results The insuline level of fasting or 30,60,120 min after OGTT were significantly higher than those in normal group(P

Objective To design a computer aided method in HIFU treatment system to monitor the size,shape and location of HIFU lesion automatically.Methods According to ultrasound image's characters of high noise,low resolution and weak edge,a double zero level set,double speed approach was proposed to extract the contour of organ and lesion area.The serial "lice" contours were used to reconstruct three dimension(3D) HIFU lesion area in the sample.Results Experiments show that level set contour extraction method based 3D reconstruction is helpful in monitoring the size,shape and location in the organ.Conclusion This method has the feasibility to be introduced as an auxiliary technique monitoring HIFU lesion area automatically.

Objective:The abstraction of characteristics in CT perfusion image is crucial in the clinical diagnosis of brain infarction and cerebral tumor.Methods:After describing the relevant parameters of CT cerebral perfusion imaging,such as cerebral blood flow (CBF),cerebral blood volume (CBV),the mean transition time (MTT) and the permeability surface (PS).With using Visual C ++ programming and CT scan images sequence obtained,the time-density curves of the brain tumor region were visualized.The more accurate hemodynamic parameters were calculated through an improved algorithm basing on the deconvolution and measuring method of the length,angle,area and other parameters.Conclusion:The quantitative analysis of feature parameter is of great benefit to clinical doctor in making timely diagnosis and treatment of brain tumor.
