Objective To evaluate the clinical value of the condition of radial artery for autogenous arteriovenous fistula ostomy by color Doppler ultrasound. Methods The condition of radial artery of 133 end-stage renal disease( ESRD) patients who received autogenous arteri-ovenous fistula ostomy were detected by color Doppler ultrasound,and compared with the postoperative parameters of fistula vascular. Results Among all 133patients,the preoperative radial artery of 95 cases were normal,abnormal in 38 cases. Ostomy surgery performed on 131 cases. Two cases gave up surgery for the poor condition of radial artery,13 cases with fistula failure. The success rate with normal radial artery (95. 8%) was higher than that with the abnormal radial artery(75%). The blood flow parameters of normal radial artery were significantly better than those of the abnormal radial artery,and 4 weeks after operation,the anastomotic blood flow and blood vessel diameter were better than those 1 week before and after surgery. Conclusion Color Doppler ultrasound that can provide preoperative data of radial artery, predict postoperative the state of fistula vascular,and monitor the conditions of postoperative fistula vascular,with better clinical value.

BACKGROUND:Erythropoietin and progenitor cel transplantation both have therapeutic effects on lower extremity arterial occlusive disease.
OBJECTIVE:To investigate the erythropoietin modification effect and magnetic resonance imaging feasibility of superparamagnetic iron oxide (SPIO)-labeled endothelial progenitor cel s in vitro.
METHODS:Rat bone marrow-derived endothelial progenitor cel s at logarithmic growth phase were randomized into four groups:endothelial progenitor cel group, SPIO labeled transfection group (pcDNA3-EPO transfection fol owed by SPIO labeling), SPIO labeled empty vector group (empty plasmid transfection fol owed by SPIO labeling), and SPIO labeling group (only SPIO labeling). 4.7T MRI was used to observe SPIO-labeled endothelial progenitor cel s. Cel proliferation, cel cycle distribution, and expression of erythropoietin protein in the four groups were measured.
RESULTS AND CONCLUSION:MRI findings showed with the increasing cel number, gradual y lowered signal intensity on T1-weighted imaging (T1WI), T2WI and T2*WI was seen, and the reduction in the signal intensity was the maximum on T2*WI sequence and the minimum on T1WI sequence. For T1WI, T2WI and T2*WI sequences, the minimum number of cel s was 2×104, 1×104 and 0.5×104, respectively. Cel proliferation and cel cycle distribution showed no significant difference among three SPIO labeling groups. In addition, the expression of erythropoietin protein was only found in the SPIO-labeled transfection group. These findings showed that under SPIO labeling, erythropoietin gene-modified endothelial progenitor cel s show no changes in cel proliferation and cel cycle, and the 4.7T MR is capable of imaging SPIO-labeled erythropoietin gene-modified endothelial progenitor cel s in vitro.

Fibroblast activation protein (FAP) is highly expressed in most epithelial tumors, and FAP inhibitors (FAPIs) have been used in tumor diagnosis and treatment. Taking FAP as the target, new kinds of tumor imaging and therapeutic radiopharmaceuticals can be developed. FAPIs have been used in the preclinical and clinical researches as the carrier of tumor imaging and treatment. This article reviews the research progress of FAPIs in nuclear medicine imaging and treatment.

The medical students, Shanghai Jiaotong University School of medical from 5- year,7-year, 8-year to general of academic, received evidence-based medicine (EBM) education. The students' background and attitudes about EBM were different. Teaching EBM should pay attention to the relationship of EBM and basic courses, especially for deferent students. Teaching EBM should transform from imparting basic knowledge to learning skills on their own initiative.

Objective To explore the significance and important measure of integrative treatment of multiple trauma patients with severe craniocerebral injury in emergency center. Methods One hundred and forty-eight multiple trauma patients with severe craniocerebral injury in emergency center from November 2002 to February 2006 were analysed retrospectively. Result In total 148 cases, 72 were cured and 26 dead, 7 were in status of plant man, 17 experienced severe deformity, and 26 did mild deformity. Conclusion Multiple trauma patients with severe craniocerebral injury usually experience a serious situation and rapid development. Therefore emergency doctors are required for organizing salvage of such patients, at the same time treatment and diagnosis are implemented. Firstly the most important key to successful salvage is appropriate disposal of fatal injury and early elimination of shock. Proper surgical choice, especially at the first time, inspection and protection of visceral functions, and attention to nutritional support are other vital methods to gain more successful salvage. ICU is also emphasized for its essentiality.
