0.05 ).The detection rate of IRC by B-ultrasound accounted for 98.2%(108/110).The rate of surgical excision in IRC was 92.2%(107/116).Stage Ⅰ to Ⅱ lesions were found in 69.0% of the patients with IRC and in 49.3% with CRC.Stage Ⅲ to Ⅳ lesions were found in 31.0% of the patients with IRC and in 50.7% with CRC.Patients were followed up postoperatively for a mean of (45?40) months.The 3- and 5-year cancer specific survival rates were significantly higher in IRC than those in CRC (86.5% and 81.3% vs 70.8 % and 64.2%, P

[Objective]To study the expression of Cad-Ⅱ gene in bone marrow mesenchymal stem cells(MSCs) transfected with Cad-ⅡcDNA after autografted into the bone defects. [Method]The experimental model of ilium segment defect was established in 20 Japanese white rabbits.The rabbit MSCs were isolated,cultured and expanded in vitro,and then the MSCs,transfected with Cad-Ⅱ and compounded with collagen sponge were autografted into the ilium segment defect.At 4 weeks of operation,the MSCs/ collagen sponge were excised,and the expression of Cad-Ⅱ was evaluated with RT-PCR and immunohistochemical methods.[Result]All of the bone defects treated with implants exhibited new bone formation at 4 weeks postoperatively.In the transfection group,Cad-Ⅱ gene mRNA expression was higher than that in the control group(P

The factor of antiapoptosis in cancer is recently identified as survivin. Survivin is prominently overexpressed in embryonic and fetal tissues, and various human cancers. It is potentially involved in both inhibition of apoptosis and control of cell division. Recently, survivin is found to be correlated with the genesis, progress, and prognosis of urological cancer. Manipulation of the antiapoptotic pathway maintained by survivin may be beneficial for cancer therapy. Progressive research of survivin in urological cancer.

Objective To determine the protective effects of endotoxin preconditioning on the brain ischemic injury and explore its protective mechanism. Methods Global ischemia for 20 min by four-vessel occlusion model was used in 140 Wistar rats, in which 70 rats were pretreated with MPL at dose of 20 ?g/kg 24 h before global ischemia. Another 10 Wistar rats served as normal controls. Ischemic neurons and neuron density of the hippocampal CA1 region, MPO activity, TNF-? activity, IL-1? activity were assayed at 4, 12, 24, 48, 72, 120, 168 h after reperfusion. Results Pretreatment with endotoxin produced significant reductions in ischemic neuron number, MPO activity, TNF-? activity and IL-1? activity. Conclusion Endotoxin preconditioning protects brain from subsequent ischemic injury, in which the suppression of cellular inflammation may be the protective mechanism.

Objective To observe the relationship between the changes of plasma D dimer in pathogenic course and prognosis in patients with acute cerebral infarction(ACI). Methods Changes in plasma D dimer levels of 93 patients with ACI and 20 cases healthy persons were detected dynamically by Latex semi quantitative method. The relation between D dimer levels and focus size, severity of infarction and prognosis were analyzed. Results There was significant difference( P

That blind people cannot read newspapers and books as normal people do severely limited the ability of acquiring information and knowledge. Using the computer technology, an one key reader for blinds was designed. It's a high-tech assistive devices; which can convert printed newspapers and books into speeches. Therefore, it is convenient for the blinds to use it in their study and work.

Objective To discuss the clinical value of u ltrasound-guided stereotactic biopsy and excision using the Mammotome system in the treatment of benign breast lesions. Methods A retrospecti ve analysis was made on the efficacy of ultrasound-guided Mammotome biopsy and e xcision in the management of 61 patients clinically diagnosed as having benign b reast lesions between October 2001 and October 2002. Results T he lesions were histologically confirmed as fibroadenoma in 51 patients and mast opathia in 10 patients. The operative time was 20.6?4.1 min. All procedures w ere performed smoothly. Of the 61 patients, no infection or breast deformity occ urred on short-term follow-up examinations (1 month) except for mild subcutaneou s hemorrhage in 3 patients, and no obvious scarring was seen on long-term follow -up (2 years). Recurrence was found in only 2 patients. Conclusions Treatment of benign breast diseases by the Mammotome system can offer comp lete excision of the lesion, minimal invasion, a low recurrence rate, and good c osmetic outcomes.

Computed tomography perfusion imaging can accurately and promptly provide hemodynamic parameters of brain tissues after stroke,and it has a good correlation with the accepted hemodynamic measurement,the parameters got from xenon-computed tomography, functional magnetic resonance imaging and positron emission tomography.Therefore,CTP has been widely used in predicting the studies of ischemic penumbra after stroke.
