Objective:To systematically assess the value of 2 dimension color Doppler ultrasound(2D-CDUS) in diagnosis,surgical treatment and interventional therapy of carotid artery stenosis. Methods: Twenty seven carotid stenosis patients were examined before and after operation with 2D-CDUS. The morphology and hemodynamic of carotid artery were detected. Results: Pre-operative examination showed that there were 17 cases with stenosis degree being 50%-70%, 2 cases 71%-79%, 5 cases 80%-90%, 3 cases 90%-99%. Twelve cases were operated on with carotid endarterectomy(CEA), 15 cases with percutaneous transluminal angioplasty and stent(PTAS). After operation all the vessels with CEA were patent, colored well and blood velocity was close to normal. Residual intima was observed floating in the blood vessel in only one patient. In the patients treated by PTAS, the location and courser of the stents were normal,and the vessels were patent. Conclusion: 2D-CDUS is convenient to use and non-invasive, which can assess extracranial carotid stenosis accurately before operation, assess the curative effect and detect the complications after operation.

Objective:To assess the value of Transcranial Two Dimensional Color Doppler Ultrasound(TC-2D-CDUS) in diagnosis of carotid artery stenosis and in follow-up study after surgical treatment.Methods: Thirteen patients with carotid artery stenosis, who were excluded from vertebral or intracranial diseases, were detected before and after operation with TC-2D-CDUS. Results: TC-2D-CDUS indicated that 2 patients' image were not satisfactory, and the blood velocity of middle cerebral artery (MCA) in the same side of lesion was lowered to different extents in the other 11 patients. The waveform was blunted in 3 patients with their systolic peak disappeared, acceleration time prolonged, and the direction of the anterior cerebral artery(ACA) in the same side inverted.After operation,TC-2D-CDUS indicated that MCA blood velocity and the direction of ACA were normal. The blood distribution was symmetric in bilateral brains. Conclusion: TC-2D-CDUS can provide intracranial hemodynamic information. It can be used in the follow-up study after operation,helping to make accurate judgement and discover complications.

Objective:To research on the radio frequency ablation (RFA) combined with the clinical effect of chemotherapy in patients with advanced non small cell lung cancer and lung metastasis. Methods:From 2011 May to 2012 in our hospital 06 months 60 cases of metastatic non-small cell lung cancer and lung cancer patients, divided into radio frequency ablation(RFA) combined with chemotherapy group of 30 cases and a simple chemotherapy group 30 cases, referred to as the treatment group and the control group. To observe the change of tumor volume in patients with poor survival rate, years, tumor recurrence rate, and postoperative complications.

Serine/ aginine rich(SR)protein,SR protein kinase and other enzymes participate in the composition of alternatively spliced tissue factor(asTF). Recently researchers have found that this protein takes a part in tumor angiogenesis,tumor progression,metastasis and so on,so the detection of its clinical content will be very significant.

Objective To investigate the effects of traditional transmyocardial laser revascularization (T-TMLR) and non-transmural myocardial laser revascularization (N-TMLR) on myocardial ischemic and necrotic areas and angiogenesis. Methods In rabbit models, using Evans′ blue -TTC stain and HE stain technique for measuring ischemic and necrotic areas and observing angiogenesis. Results After T-TMLR and N-TMLR,compared with the control group, the ischemic areas significantly decreased and significant elevation of angiogenesis was observed. But no difference in necrotic areas was observed among the three groups. Conclusion N-TMLR can achieve the same effects with T-TMLR. Inducing angiogenesis via laser channels and decreasing ischemic area may be one of the predominant mechanisms of TMLR whereas laser channels themselves open or not has no relation to the effects of TMLR.
