Objective By using digital three-dimensional (3D) model of abdominal and pelvic vessels to investigate the relationship between the angle/position of the bifurcation of bilateral common iliac arteries and the length of the common iliac artery, thus to guide the endovascular interventional catheterization manipulation. Methods A total of 439 patients, who received abdominal and pelvic CTA at authors’ department during the period from Sep. 2011 to May 2013, were included in this study. By using digital 3D reformation technique, the 3D model of the abdominal and pelvic vessels as well as the lumbosacral vertebrae was established in all patients. With the help of mimics and geomagic software the angles between the left and right common iliac arteries and the lengths of common iliac arteries were determined, and the lumbar vertebra corresponding to the bifurcation of common iliac arteries was recorded. Using statistical software, the relationship between the bifurcation angle of bilateral common iliac arteries and the corresponding lumbar vertebra as well as the length of common iliac arteries was analyzed. Results The digital 3D model of the abdominal and pelvic vessels as well as the lumbosacral vertebrae was successfully reconstructed in all 439 patients. Both the angle between the left and right common iliac arteries and the corresponding lumbosacral level of bifurcation angle were clearly demonstrated on the model. The average angle was 49.1° ± 12.4°. The bifurcation was located at L3 -L4 level in 38 cases, at upper one-third level of L4 in 63 cases, at middle one third level of L4 in 89 cases, at lower one-third level of L4 in 135 cases and at L4 -L5 level in 114 cases. The average length of the left and right common iliac artery was (45.6 ± 15.6) mm and (43.3 ± 15.4) mm respectively. Pearson correlation analysis indicated that a negative correlation existed between the angle and the position level of the left and the right common iliac artery (r = -0.172, P< 0.05), and a negative correlation also existed between the angle and the length of the common iliac artery (left: r = -0.171, P<0.05; right: r = -0.164, P < 0.05). Conclusion The lower the opening position of the left and right common iliac artery is, and the bigger the intersection angle is, the shorter the length of corresponding common iliac artery will be. In this case, catheterization via femoral artery to contralateral iliac artery is a short path, and the catheterization procedure is easy to manipulate with higher success rate. On the contrary, the catheterization will be difficult, and the use of loop-technique will be needed. The digital 3D model of the abdominal and pelvic vessels as well as the lumbosacral vertebrae can help select the optimal catheterization path.

Objective To explore the role and mechanism of microRNA-15b in the regulation of epithelial-mesenchymal transition (EMT) of human peritoneal mesothelial cells (HPMCs).Methods PCR assay was used to determine the expression of microRNA-15b in the HMrSV5 induced by 138mmol/L high glucose for 24 h.MicmRNA-15b mimic or inhibitor was transfected into human peritoneal mesothelial cells (HMrSV5) to over-express or down-regulate microRNA-15b.The cells were then incubated with 138 mmol/L high glucose for 24 h,and the expressions of E-cadherin(E-Cad),Vimentin (VIM),Fibronectin(FN) and Smad7 were detected by real-time PCR and Western blotting respectively.Results microRNA-15b in the HMrSV5 ceils was over-expressed and down-regulated.Increased level of microRNA-15b was obtained in HMrSV5 cells treated with high glucose.In vitro,high glucose led to the up-regulation of vimentin as well as fibronectin and the down-regulation of E-cadherin in HMrSV5 cells (all P ＜ 0.05),which indicated EMT and fibrosis.Suppression of microRNA-15b by transfection with microRNA-15b inhibitor partially reversed the EMT and fibrosis changes (P ＜ 0.05),while over-expression of microRNA-15b by transfection with microRNA-15b mimic obviously enhanced the EMT and fibrosis changes (P ＜ 0.05).Conclusions MicroRNA-15b mediates high glucose induced EMT in human peritoneal mesothelial cells by the inhibition of Smad7 possibly.MicroRNA-15b maybe a new target for the prevention and treatment of peritoneal fibrosis during peritoneal dialysis (PD).

Objective:To investigate the effect of gemcitabine on myeloid derived suppressor cells (MDSC) in the spleen of B lymphoma cell-bearing mice, and the therapeutic effect of gemcitabine combined with intratumoral injection of dendritic cells (DCs) in treatment of large B lymphoma. Methods: BALB/c mice were inoculated subcutaneously with B lymphoma A20 cells; large tumors were formed 30 d after inoculation. Gr-1~+ CD11b~+ MDSC proportion in the spleen was analyzed by flow cytometry before and after gemcitabine treatment. Splenic MDSC sorted by immunomagnetic beads was further treated with gemcitabine, and then the apoptosis of MDSC was examined by Annexin-V/PI staining. Tumor growth and survival time of A20 tumor-bearing mice were observed after treatment with gemcitabine and intratumoral injection of DCs. Results: Splenic Gr-1~+ CD11b~+ MDSC ratio in A20 cell-bearing mice was 10 times higher than that in the normal mice. Gemcitabine induced apoptosis and necrosis of purified MDSC in vitro in a time-dependent manner. The percentage of MDSC in the spleen of A20 tumor-bearing mice was decreased after injection of a single dose of gemcitabine. Gemcit-abine or intratumoral injection of DCs alone inhibited growth of tumor to a certain degree, with the mean survival periods of mice in the gemcitabine, DCs, and untreated groups being (48.8±3.6) d, (47.2±7.4) d, and (38.8±2.2) d, respectively. Gemcitabine chemotherapy combined with intratumoral DC injection resulted in continuous shrink of the tumors, and 60% of the mice survived for more than 90 d. Conclusion: Gemcitabine can effectively eliminate splenic MDSC in tumor-bearing mice. Gemcitabine chemotherapy and DCs immunotherapy can work synergistically in the treat-ment of huge lymphoma. These results provide an experimental basis for the comprehensive chemotherapy and immunotber-apy of relapsed or refractory lymphoma.
