Objective To evaluate clinical outcome of patients treated with endovascular dilation and stent placement for ilio-femoral venous postthrombotic syndrome (PTS).Methods 42 PTS cases were enrolled in our group from June 2003 to December 2011.Dilation and stent placement in stenosis/ occlusion of ilio-femoral veins were performed in all cases,temporary femoral arteriovenous fistula was established in 24 cases.Results These were not severe perioperative complications.All patients were followed up for 8-75 months.Preoperative limb ulcers in 5 cases were healed.Early thrombosis in stents found in 3 cases was cleared by catheter directed thrombolysis (CDT).Severe in-stent restenosis (＞ 50％)was found in 10 cases,treated with dialation or re-stenting.Primary patency,assisted primary patency and secondary patency rates were 75％,78％,80.1％;64.1％,67.1％,69.6％;63.8％,65.3％,66％;61.7％,65％,65.2％,respectively,at 6 months,12 months,24 months and 36 months.Postoperative Venous Clinical Severrity Score (VCSS) decreased (P =0.000).There was statistical significant improvement in every dimension evaluated by the MOS item short from health survey(SF-36) after operation (P =0.000).Conclusion Ilio-femoral venous stenting is a safe and effective treatment for PTS and with good clinical midterm results.

Objective To establish a monitoring database of historical Oncomelania hupensis environments at grass?root lev?el for schistosomiasis prevention based on Google Earth(GE),so as to improve the management efficiency of historical O. hu?pensis environments. Methods GE was labeled with the information about the historical O. hupensis environments through add?ing landmark,path and polygon. Meanwhile,POCO web album was used to storage the practice situation pictures of the environ?ments,which could be imported into GE so that the environments could be monitored dynamically. Results There were 553 historical O. hupensis snail environments in Yangjian Town,Xishan District,Wuxi City and the accumulative area was 506 000 m2. Among these environments,224(40.5%)were Class IV environments,accounting for 40.5%of accumulative area. Conclu?sions The monitoring database of historical O. hupensis environments based on GE at country level is established successfully and it can be used to manage the historical snail environments visually and monitor the changes dynamically.

Objective To investigate the therapeutic effect and safety of the clip with the flossmethod during endoscopic submucosal dissection for early gastric angle cancer. Methods A total of 27 gastric angle lesions diagnosed as early gastric cancer were treated by ESD. They were randomized to two groups, routine ESD group and clip with the flossgroup. The procedure time, complication events, en-block resection rate and complete resection rate were compared between the two groups. Also,the learning time was divided to two stages and the learning curve was studied according to the resected specimen areas per minute. Results The en block rate was 85. 7%(12/14) in the routine ESD group and 100. 0%(13/13) in the clip with the floss group. The procedure time in the clip with the flossgroup was significantly less than that in the routine ESD group (the median time 30 min VS 40 min, P =0. 011) . Perforation and the post operative bleeding did not occur in either group. The ESD learning curving during the first learning period and the mean resected specimen (area/min) in theclip with the floss group were larger than routine ESD group(30±6 mm2/min VS 20±5 mm2/min,P=0. 01). However, no difference presented during the second learning period between the two groups. Conclusion Clip with the flossmethod during endoscopic submucosal dissection for early gastric angle cancer as a novel procedure is safe, efficacious and worthy to recommend to beginning learners.

Objective:To determine the expression of the full-length (NK1R-FL) and truncated (NK1R-Tr) neurokinin-1 receptor (NK1R) and the neurokinin-2 receptor (NK2R) in breast cancer tissues and cell lines, as well as to study the effects of the NK1R and NK2R antagonists on the growth of breast cancer cells. Methods:Immunohistochemistry and Western blot assays were used to detect NK1R, NK1R-FL, and NK2R expression in clinical samples of primary breast cancer tissue, benign lesions, and normal breast tissue, as well as in different breast cancer cell lines. Cell proliferation and soft agar growth tests were performed on cells treated with the NK1R and NK2R antagonists to study the ectopic overexpression of NK1R-FL and NK1R-Tr in breast cancer cell lines. Results:Total NK1R expression was detected in the breast cancer tissues, benign lesions, and normal breast tissues. Compared with the normal breast epithe-lia and benign breast lesions, the expression levels of NK1R-FL and NK2R decreased in the carcinoma. These changes were also relat-ed to the carcinoma type, histological grade, lymph node metastasis, HER2 and Ki-67 expression, and estrogen and progesterone recep-tors in breast cancer. The expression levels of NK1R-FL and NK2R were high in the HBL-100 breast cell lines of para-neoplastic tis-sues, but NK1R-Tr expression was low. The MDA-MB-231, T-47D, and MCF-7 cells only expressed NK1R-Tr. NK1R-Tr or NK1R-FL overexpression caused the decreased inhibition rate or increased levels of the NK1R and NK2R antagonists in the breast cancer cells. Conclusion:NK1R-FL and NK2R are co-expressed in normal cells. NK1R-Tr is highly expressed in breast cancer cells and exerts nega-tive feedback to regulate NK1R-FL and NK2R expression in all cells, especially cancer cells.

Objective To study the effect of endothelial progenitor cells(EPCs) transplantation on chronic deep venous thrombosis.Methods Bone marrow-derived mouonuclear cells (BMMNCs) were isolated from rat bone marrow by ficoll and cultured with EGM-2MV medium.A rat model of chronic deep vein thrombosis was established by partial ligation of the inferior vena cava and intravenous injection of thrombosin.Model rats were randomly divided into three groups:A(n =25),EPCs group,1 ml 10~6 EPCs transplantation;B(n = 25),EGM-2MV medium group,1 ml EGM-2MV medium transplantation;C (n =25),control group,without any treatment.After transplantation,HE staining and immunohistochemical staining was conducted to detect recanalization of the inferior vena cava.Western blotting of inferior vena cava thrombosis was used to detect VEGF,bFGF protein expression changes.SPSS13.0 software was used for analysis.Results Compared with group B and C,VEGF,bFGF protein significantly increased in group A.The recanalization capillary density was significantly higher in group A than that in group B,and C (P ＜0.05).The neovascularization was identified by immunohistochemical staining using vWF antibody,as endothelial cells.Conclusions EPCs were the precursor of endothelial cells,when transplanted into the deep vein thrombos,initiating angiogenesis and accelerating organization and recanalization of vein thrombus.
