Objective To evaluate puncture technique in thoracic endovascular aortic repair with abdominal aortic aneurysm and assess the feasibility and safety of using a pre-close technique for puncture and closure of femoral access sites. Methods From May 2010 to August 2013, the pre-close technique which involved two 6 F per-close ProGlide devices deployed in the femoral artery before upsizing to a 18-25 F sheath and one or two deployed before upsizing to a 14-16 F sheath were applied to 42 patients with abdominal aortic aneurysm (group A). Forty-seven patients using surgical femoral cutdown from December 2006 to April 2010 were enrolled into group B. The rate of technical success, time from procedure to the aortic delivery, operation time, low limb braking time, local complication, time from procedure to discharge, local vascular diameter after 3 months was evaluated and compared between two groups. Results There was no significant difference in endograft external diameter between two groups ( P>0.05). The rate of technical success was 97.62%(41/42) in group A and 95.74%(45/47) in group B, and there had no significant difference (P>0.05). Time from procedure to the aortic delivery, operation time and time from procedure to discharge in group A were significantly shorter than those in group B: (21.79 ± 5.79) min vs. (41.37 ± 11.79) min, (127.66±37.83) min vs. (157.84±42.71) min, (6.59±1.89) d vs. (9.14±2.57) d, P<0.05. The incidence rate of local complications, low limb braking time, and local vascular diameter after 3 months had no significant difference between two groups:7.14%(3/42) vs. 8.51%(4/47), (8.51± 1.83) h vs. (8.38±1.79) h, (1.05 ±0.36) mm vs. (0.98 ±0.31) mm, P>0.05. Conclusion The puncture technique with per-close ProGlide is safe and effective in percutaneous endovascular aortic repair which can be adopted as an alternative technique of surgical femoral cutdown approach in patients with abdominal aortic aneurysm.

Objective To investigate the effect of rosiglitazone on the CD4+regulatory T cells in the patients with latent autoimmune diabetes in adults(LADA).Methods The CIM+T cells from IADA patients were isolated with anti-CD4-dynal magnetic beads.The expression of Foxp3 mRNA,along with peroxisome proliferators activator receptors gamma(PPARγ)mRNA and TGF-131 mRNA was determined.The effect of rosiglitazone on CD4+T cells was measured,after treated with rosiglitazone for 48 h.Cell viability was assessed by Mtit assay.The proliferation was assayed with 3 H-TdR.Two-color staining(anti-CD4,anti-CD25)flow cytometric analysis was employed to measure the percentage of CD4+CD25+T cells of Deriph eral blood.Resuits PPARγmRNA was expressed in peripheral CD4+T lymphocytes.RosiglitazoBe inhibited phytohemagglutinin(PHA)-induced human CD4+T cell proliferation in dose dependence.The percentage of CD4+CD25+T cells showed no significant change after the peripheral blood culture with 1 μmol/Land 10μmot/L rosiglitazone.10 μmol/L of rosiglitazone induced Foxp3 mRNA expression in vitro (3.27fold,P<0.05),whereas TGF-β1 mRNA expression did not change.Furthermore,only 1 μmol/L of rosiglitazone could promote Foxp3 mRNA expression if adding IL-2(10 U/m1)in cultures(3.48 fold.P

Objective To investigate effect of Rho kinase combined with Sheng Mai injection on tumor necrosis factor alpha ( TNF-α) , interleukin-10 (IL-10), intercellular adhesion molecule-1 (ICAM-1) and adhesion molecule CD11/CD18 in patients withⅡ°superficial burn.Methods 48 cases patients withⅡ°superficial burn were collected and divided into experimental group and control group, according to different therapy, 24 cases in each group.The two groups were given symptomatic treatment such as anti-infectious, keep warm, anti-shock, pain-relieve and wound-healing treatment, the control group were given Rho kinase on the basis of symptomatic treatment, and experimental group were given Sheng Mai injection on the basis of control group, for a course of two weeks.The serum TNF-α, IL-10, ICAM-1 and CD11/CD18 levels were compared after treatment. ResuIts After treatment, the serum TNF-α, IL-10, ICAM-1 and CD11/CD18 levels after treatment were lower than those before treatment in two groups (P<0.05).Compared with control group, the levels of TNF-α, IL-10, ICAM-1 and CD11/CD18 were lower than those of experimental group (P<0.05).ConcIusion Rho kinase combined with Sheng Mai injection could significantly reduce the levels of TNF-α, IL-10, ICAM-1 and CD11/CD18 in patients with Ⅱ°superficial burn.

Combination chemotherapy and nanoparticle drug delivery are two promising strategies in cancer treatment. The use of multiple therapeutic agents in combination provides synergistic effects among different drugs against cancer cells and suppresses drug resistance through distinct mechanisms of action.Nanocarriers can improve anti-tumor effects of drugs and reduce systemic toxicity through delivering drugs into the tumor tissue specially. Recently, many studies are aiming to encapsulate multiple agents into nanocarriers to optimize the anti-tumor effects. In the present review, the recent advances of nanoparticle platforms applied with co-delivering two or more drugs were summarized and the various combination strategies based on nanoparticles in oncology were discussed.

Objective To investigate the correlations between the time of thoracic endovascular aortic repair (TEVAR) and prognosis in patients with type B acute aortic dissection (AADB). Methods The clinical data of 156 AADB patients with TEVAR was retrospectively analyzed and divided into 3 groups according to the time from onset of symptom to TEVAR:less than seven days was deifned as group 1 (G1, n=87), seven days to fourteen days group 2 (G2, n=48);more than fourteen days was group 3 (G3, n=21). The status of aortic reconstruction at three months TEVAR, in-hospital mortalities, mean hospital expense and length of stay were compared among three groups. Results Before TEVAR, there was no signiifcant differences in the ratio of smallest true lumen diameter and largest false lumen diameter amony the three groups (0.47±0.33, 0.42±0.18, 0.47±0.27, respectively, P>0.05). At three months after TEVAR, the ratio of largest true lumen diameter and largest false lumen diameter among the three groups was signiifcantly greater in group 1 (1.76±0.51) than group 2(1.42±0.30) and group 3(1.34±0.34, P < 0.05), when there was no signiifcant difference between the later two groups. Complete aortic reconstruction (8 from group 1 and 4 from group 2) was achieved in 12 patients at 3 months after TAVAR. Eight patients died during hospitalization, 5 from visceral ischemic, 2 from proximal aortic dissection, one patient from sudden death. Compared with G3, the hospital expense of group 1 and group 2 was cut down about ￥20000. Length of stay was signiifcant greater in group 3 than in group 1 and group 2 (P<0.05). Conclusions Early TEVAR for AADB was safe and beneifcial for aortic reconstruct and reducing the hospital expense and length of stay.

Objective:To investigate the characteristics of magnetic resonance imaging and clinical application of multi-modality magnetic resonance imaging (MRI) for evaluating the response of neoadjuvant chemotherapy (NACT) in inflammatory breast cancer (IBC).Methods:A total of 36 IBC patients were enrolled in the study.The morphological, hemodynamic and diffusion-weighted imaging features of MRI were analyzed. Eleven patients underwent MRI examination before and after NAT. The imaging changes were analyzed and the efficacy of NACT was evaluated.Results:There were 38 identified breast carcinoma in these 36 cases, among which abnormal skin thickening and enhancement, extensive edema was found in 37 breast lesions. Enhancement of breast lesions in 25 cases was non-mass-like enhancement. Diffusion limitation was found in all lesions. The number of vessels in affected side was more than that in healthy side in MIP images. Thirty three cases had axillary lymph node enlargement.The sensitivity and specificity of MRI in evaluating residual breast tumors and vascular thrombus were high, but the evaluation of axillary lymph nodes was relatively low.Conclusions:Multi-modal MRI can be used for early and accurate diagnosis of IBC. It can also be used to predict and evaluate the effect of neoadjuvant chemotherapy.
