10 mm) treated by CBA or BA were retrospectively analyzed. CBA was used in 74 patients and BA in 43 patients. Results Initial success (residual restenosis ≤30% with no major complications) was achieved in 99% of cases in CBA group and 100% in cases of BA group. Follow-up angiography was performed in all patients at (5.8?1.6) months. The diameter stenosis percent after CBA was lower and the instant gain after CBA was larger than that after BA (11.81%?9.17% versus 26.33%?10.04% and 1.96?0.51 mm versus 1.51? 0.54 mm, respectively; P

Objective To explore the effects of oxidative stress in porcine iliac endothelial cells(PIECs) induced by high glucose. Methods After being intervened by high glucose for some time, dihydroethidium (DHE) or dihydrorhodamine 123 (DHR123) was used as a reactive oxygen species(ROS) capture. The mean fluorescent intensity(MFI) of above probes which were the products of intracellular oxidation was detected by fluorescent microscopy and flow cytometry, and the level of ROS was thus measured. With lucigenin as chemiluminescence agent, luminescence changes were detected by chemiluminescence analyzer after addition of NADPH to observe the effect of high glucose on activity of NADPH oxidase(NOX). Results Intracellular MFI was markedly elevated with the concentration of high glucose and time of exposure to high glucose. It was revealed by flow cytometry that the NOX activity was significantly activated compared with normal medium treated PIECs(P

Transforming growth factor-β is an important cytokine with various bioactivities, including embryonic development, wound healing, chemotaxis and cell cycle regulation. Epithelial-mesenchymal transition (EMT) is the main pathway of tumor cell to obtain the ability of invasion and metastasis. The TGF-β is the key factor known to induce EMT in cancer cells and plays an important role in the process. In recent years, some progress has been obtained. Some TGF-β inhibitors have approved in the market or in clinical trials. TGF-β inhibitors can play an important role on the treatment of tumors, glaucoma, liver and kidney fibrosis disease and scar repair. Novel TGF-β inhibitors reported in recent years were reviewed in this article.

Objective To evaluate the feasibility, safety and effectiveness of interventional occlusion with thin waist occluder for perimembranous ventricular septal defect with pseudoaneurysm. Methods During the period from March 2008 to March 2013 at Shanghai Yodak Cardiothoracic Hospital , interventional occlusion with thin waist occluder was carried out in a total of 96 patients with perimembranous ventricular septal defect (VSD) complicated by pseudoaneurysm. The patient’s age varied from 2 years to 36 years. Before the procedure, routine left ventricular angiography and ascending aortic angiography were carried out. Left ventricular angiography and ascending aortic angiography as well as the transthoracic ultrasonography were performed immediately after the procedure to observe the therapeutic results. Follow-up checkups with transthoracic ultrasonography, EKG and chest X-ray film were conducted at one week as well as at one, 3, 6 and 9 months after the surgery were conducted. Results Successful occlusion of VSD was obtained in 93 patients, with a success rate of 96.8% (93/96). After the surgery, small amount of shunt flow was detected in 8 patients, which disappeared within 48 hours in 7 patients, and in the other one the shunt flow disappeared one month later which was confirmed by follow-up examination. After the treatment, complete right bundle branch block occurred in 4 patients, complete left bundle branch block in 5 patients, and transientⅢdegree atrioventricular block in one patient. The conduction block disappeared at the time of discharge in all patients. The left ventricular end-diastolic diameter (LVEDD) decreased from preoperative (47.5 ± 5.2) mm to postoperative (45.2 ± 5.1) mm, the difference was statistically significant (t = 18.33, P < 0.01). During the follow-up period lasting for 9 months, no delayed cardiac arrhythmia, valve damage or sudden death occurred. Conclusion For the treatment of perimembranous ventricular septal defect with pseudoaneurysm, interventional occlusion with thin waist occluder is safe and effective with excellent mid-term effect. Based on the imaging findings, including the location, shape, ruptured orifice, number of the perimembranous pseudoaneurysm as well as the distance between the pseudoaneurysm and the aortic valve, to select suitable occluder and proper occlusion site is the key to ensure a successful surgery.

To optimize the extraction technology of the total saponins in Dipsaci Radix, the extraction efficiency of total saponins was investigated with respecting to three variables including time, ethanol concentration and liquid-to-solid ratio. On the basis of a series of one-factor-at-a-time experiments, a polynomial regression model equation was fitted by the combined use of central composite experimental design and regression analysis. By analyzing the regression model using response surface analysis, the optimum extraction conditions of total saponins from Dipsaci Radix were identified as follows: 7 times of 55% alcohol, refluxing 3 times, 2.8 hours every time, and the extraction efficiency of total saponins was up to 0.201 1 g·g-1 and the asperosaponin Ⅵ was up to 0.015 4 g·g-1 under the optimized conditions. Confirmatory experiment indicated the good prediction ability of the established model and provided the basis for further development and utilization of Dipsaci Radix.

Objective To investigate the correlation of XRCC1 Arg194Trp Arg399Gln Single nucleotide polymor-phism (SNP) with radiotherapy response of squamous cell carcinoma of cervix. Methods Patients with exogenous type cer-vical squamous cell carcinoma confirmed by histopathology were selected for our study. These include:patients in stageⅠ(4 cases), patients in stageⅡ(36 cases), patients in stageⅢ(30 cases), patients in stageⅣ (3 cases). There are 30 patients with tumor diameter less than 4 cm and 43 patients with tumor diameter over 4 cm in our test. There are 36 cases with dose point A less than 80 Gy and 37 cases with dose point A over 80 Gy . Radiotherapy outcomes showed 47 cases of complete re-mission and 26 cases of part remission. Polymorphisms Arg194Trp, Arg399Gln of XRCC1 gene in 73 cervical cancer pa-tients were analyzed by mismatch amplification polymerase chain reaction (MAMA-PCR). Results Arg/Arg, Arg/Trp, TrP/Trp of Arg194Trp genotype distribution were 31 (42.5%), 37 (50.7%), 5 (6.8%) respectively. Arg/Arg, Arg/Gln, Gln/Gln of Arg399Gln distribution were 6 (35.6%), 39 (53.4%), 8 (11.0%) respectively. The response to radiotherapy was not statistical-ly significant in three genotypes, Arg/Arg, Arg/Trp, TrP/Trp of XRCC1 at codon 194(P>0.05). Neither was XRCC1 at codon 399. Multivariate analysis showed that late clinical stage was a risk factor of part remission. Conclusion SNP of XRCC1 gene at codon 194 and codon 399 could not predict clinical response of patients with squamous cell carcinoma of cervix to ra-diotherapy. The patients with advanced cervical cancer had poor response to radiotherapy.
