One case was misdiagnosed. Surgical management was carried out in 42 cases and postoperational radiation therapy or chemotherapy was performed. The 1–5 year postoperative survival rate was totally 100%.Conclusion: B-ultrasound, especially color Doppler flow imaging, with the advantages of noninvasiveness and inexpensiveness was most useful and should be firstly employed in diagnosing the testicular tumor. The favorable prognosis can be obtained if an early diagnosis is made and the early treatment is performed. Key words testicular tumor - B-ultrasound - color Doppler flow imaging展开更多

Comparison of the trascranial Doppler (TCD) characteristics of cerebral circulation in persistent vegetative status (PVS), locked in syndrome and brain death patients. Methods. Using TCD ultrasound to detect the flow velocity and waveform patterns of middle cerebral artery (MCA) and basilar artery (BA) in patients with PVS, locked in syndrome and brain death. Results. The mean velocities of middle cerebral artery (Vmca) and basilar artery (Vba) were 30.0cm/s and 24.3cm/s in PVS patients respectively, which decreased 45.0% and 14.4% in comparing with normal value. For patients with locked in syndrome, Vmca and Vba were 49.7cm/s and 9.8cm/s, which decreased 5.0% and 61.7% than the normal value respectively. These results showed that the decrease of anterior circulation was predominant in PVS, and the decrease of posterior circulation was predominant in locked in syndrome. A unique diastolic reverse flow, short peak systolic wave or undetectable flow signal in middle cerebral artery were predominant in brain death patients, which was completely different from that of either PVS or locked in syndrome. Conclusion. TCD was a valuable tool in distinguishing PVS, locked in syndrome and brain death patients according to the differences in velocities and patterns of anterior and posterior cerebral arteries.展开更多

The results have important clinical consequences concerning type of resection or multimodal approach. Further re?nements of endoscopy will increase its signi?cance especially for early cancer. EUS has an accuracy of 80% for the primary compared to 60% for the N-staging. Therefore EUS represents the gold standard for T-staging but it is of little value for detection of lymph node metastasis.展开更多

Researches in this area home and abroad also made great progress. On the one hand due to improved high-resolution portable ultrasound instrument and probe technology, ultrasound changed from a purely clinical diagnostic into the operating room; on the other hand, with the traditional method of anesthesia increasingly unable to meet the clinical requirements, it is an objective need of technological innovation for clinical anesthesia. And ultrasound has non-invasive, real-time, visible and repeatable characteristics which are able to provide accurate data and rich means for preoperative assessment, intraoperative monitoring and treatment of pain in pre-clinical anesthesia展开更多
