Complications of vascular access are main component of vascular complication in percutaneous cardiovascular intervention.The common complications of femoral access may include hemorrhage and hematoma at access site,vasovagal reflex,pseudoaneurysm,arteriovenous fistula,retroperitoneal hematoma and deep venous thrombosis.The common complications of radial access may include radial artery spasm,radial artery occlusion,vascular injuries or hematoma at forearm and other sites,and osteofascial compartment syndrome.The common complications of ulnar and brachial accesses may include hemorrhage and hematoma at access site,upper limb and hand ischemia,and nerve injuries.Effective prevention and treatment of vascular access complications are key steps to minimize the incidence and hazards of vascular complications in percutaneous cardiovascular intervention.

Objective To study the effect of mitochondrial membrane potential and cellular membrane permeability in the neurotoxicity of artemether. Methods Mitochondrial membrane potential and cellular membrane permeability in pheochromocytoma cell and primary cultured rat neuronal cell were measured by flow cytometry, using rhodamine 123(Rh123) and PI as fluorescent dye, respectively. Mitochondrial swelling was measured by spectrometer. Results Artemether could decrease the mitochondrial membrane potential and increase the cellular membrane permeability in both cell types in a dose-dependent manner. In addition, artemether led to mitochondrial swelling with dose-effect and time-effect relationships. Conclusion The decrease of mitochondrial membrane potential plays an important role in the neurotoxicity of artemether. The drug can change the mitochondrial membrane potential and mitochondrial swelling by affecting the permeability transition pore complex located in the mitochondrial membrane, increasing cellular membrane permeability, causing an obstruction and finally leading to neurotoxicity.

Objective:To determine the diagnostic performance of dynamic contrast-enhanced MRI (DCE-MRI) in patients with recurrent or residual prostate cancer after radical prostatectomy. Methods:Studies were systematically searched in the PubMed, EMBASE, Cochrane library, SCI, CBM, CNKI, VIP, WanFang, and other databases. Additional studies were manually searched using the references of the retrieved articles. The retrieved deadline time was June 6th, 2013. Studies were eligible for inclusion based on the inclusion and exclusion criteria, and the qualities of the studies were reviewed based on the QUADAS criteria. The Meta Disc 1.4 software was used for meta-analysis, and a summary receiver operating characteristic (SROC) curve was constructed. The patient-based pooled weighted estimates of the sensitivity, specificity, diagnostic odds radio, and 95%confidence interval were calculated. Results:Among the 118 eligible studies, 7 articles (12 studies) were included in the meta-analysis. The pooled weighted estimates of the sensitivity, specificity, and the area under the curve were 0.88 (95%confidence interval:0.84 and 0.91), 0.87 (95%confidence interval:0.81 and 0.92), and 0.939 1, respectively. The pooled diagnostic radio (dOR) was 50.4 (95%confidence interval:26.0 and 97.6) and Q*was 0.876 4. Conclusion:DCE-MRI has high sensitivity and specificity in the evaluation of locally recurrent or residual prostate cancer after radical prostatectomy, in which the diagnostic efficiency of DCE-MRI combined with magnetic resonance spectroscopy is much better.
