BACKGROUNDPercutaneous transluminal angioplasty and stenting represent an effectivetreatment for hepatic artery stenosis after liver transplantation. In the first yearafter stenting, approximately 22% of patients experience in-stent restenosis,increasing the risk of artery thrombosis and related complications, and 50%experience liver failure. Although angiography is an important tool for diagnosisand the planning of therapeutic interventions, it may raise doubts, especially insmall-diameter arteries, and it provides low resolution rates compared withnewer intravascular imaging methods, such as optical coherence tomography(OCT).CASE SUMMARYA 64-year-old male developed hepatic artery stenosis one year after orthotropicliver transplantation and was successfully treated with percutaneous transluminalangioplasty with stenting. Five months later, the Doppler ultrasound resultsindicated restenosis. Visceral arteriography confirmed hepatic artery tortuositybut was doubtful for significant in-stent restenosis (ISR) and intrahepatic flowreduction. To confirm ISR, identify the etiology and guide treatment, OCT wasperformed. OCT showed severe stenosis due to four mechanisms: Focal andpartial stent fracture, late stent malapposition, in-stent neointimal hyperplasia,and *** diagnostic methods can be useful in evaluating cases in which initialangiography results are not sufficient to provide a proper diagnosis of significantstenosis, especially with regard to ISR. A wide range of diagnoses are provided byOCT, resulting in different treatment options. Interventional radiologists shouldconsider intravascular diagnostic methods as additional tools for evaluatingpatients when visceral angiography results are unclear.

DNA Vaccines Approach:From Concepts to Applications

World Journal of Vaccines 2014年第2期4卷 50-71页

DNA vaccines are the third generation vaccines based on purified plasmid preparations containing transgenes that encode antigenic/therapeutic proteins or peptides capable of triggering an immune response against a wide range of diseases. This vaccine platform presents several attributes that confer distinct advantages over other vaccine technologies in terms of safety, ease of fabrication and stability. Many aspects, such as antigen expression and especially vector design, are under study because of their great influence on immunogenicity and efficacy of DNA vaccines. In this regard, with the attempt of improving the efficiency of DNA vaccines, co-expression of stimulatory sequences and diverse vector delivery systems are being optimized. With this in mind, this review aims to giving a conceptual approach of DNA vaccines, explaining their mechanisms of action and listing the already licensed veterinary DNA vaccines presented in the market.
