The research of skin imaging technology with high frequency ultrasound / 中国医疗器械杂志

<p><b>OBJECTIVE</b>Developing a high-frequency ultrasonic skin imaging system to obtain the high resolution ultrasonic image of the skin. And further analyzing the ultrasonic images of skin to explore the imaging characteristics of skin structure and then explore the value of high-frequency imaging in the application of skin diagnosis.</p><p><b>METHODS</b>50 MHz single element ultrasonic transducer, mechanic linear scanning method is used in the imaging system. The resolution and the ability of recognize the skin issue is verified by linear target scanning and clinical trials.</p><p><b>RESULTS</b>Both the axial and lateral resolution of the system reaches 50 microm. The subtle structure of normal skin tissue is clearly visible. Some diseases have obvious appearance in the image.</p><p><b>CONCLUSIONS</b>50 MHz ultrasonic skin imaging system is of high resolution and is valuable to skin structure detect and disease diagnosis.</p>

The operation timing and operative procedure for sevese acute pancreatitis / 中国普通外科杂志

Objective To investigate the operation timing and operative procedure for serious acute pancreatitis(SAP).Method To analyze retrospectively the clinic data of 56 cases treated by operation.Result 54 cases were cured,who treated by operation within 48h after SAP onset. All the 2 cases dead of multiple organs failure who underwent operation 5-6d after SAP onset.Conclusions When SAP advanced to have indications of operative treatment,an-operation should be done as early as possible, no metter the time from the onset of SAP is long or short.
