  • RESEARCH ADVANCE OF GENE THERAPY FOR PERIPHERAL ARTERIAL DISEASE USING HEPATOCYTEGROWTH FACTOR

    Objective To introduce the studies on gene therapy for peripheral arterial disease(PAD) using plasmid DNA encoding human hepatocyte growth factor(HGF) gene. Methods Recent articles including preclinical and clinical studies were reviewed. Results Intramuscular injection of human HGF plasmid DNA into rat, rabbit, dog and diabetic hindlimb ischemic models, resulted in a significant increase in capillary density, blood flow and blood pressure. but no influence on tumor growth in mice. A clinical trial wasperformed in ischemic limbs of 6 critical limb ischemic patients, the result showed that no side effect caused by gene transfer was detected in all 6 patients.The pain scale and long diameter of ischemic ulcers were reduced. Conclusion Intramuscular injection of naked HGF plasmid DNA could be a safe and potential treatment for PAD.

  • 心脏搏动下经右心室微创封堵婴幼儿肌部室间隔缺损

    目的探讨心脏搏动下经右心室微创封堵婴幼儿肌部室间隔缺损的临床效果。 方法回顾性分析2010年1月至2013年1月兰州大学第一医院心血管外科39例肌部室间隔缺损患儿行心脏搏动下经右心室微创封堵肌部室间隔缺损的临床资料,其中男26例、女13例,年龄10个月至3岁,体重6~15kg。应用经胸超声心动图进行术后随访,观察封堵器的位置,有无移位、有无残余分流、塑型情况及毗邻瓣膜是否开闭等。观察各瓣膜反流情况、各瓣膜口血流及房室腔的变化,心脏功能、肺动脉高压恢复情况等。 结果39例患儿中36例(92.3%)植入封堵器成功封堵,有3例患儿(7.7%)经食管彩色超声心动图(TEE)诊断不适宜行封堵治疗,其中1例由于右心室流出道有异常肌束,2例由于边缘过短不适宜行封堵手术,而改为体外循环下心内直视手术。36例患儿随访6个月以上,经胸超声心动图显示无封堵器脱落、移位,无溶血和房室传导阻滞,人工瓣膜表面光滑,无异物。心脏明显缩小,心功能正常,无神经系统并发症发生。其中3例术后存在轻微的残余分流,随访6个月均消失。 结论心脏搏动下经右心室微创封堵肌部室间隔缺损是肌部室间隔缺损一种较优的治疗选择,在经食管彩色超声心动图引导下手术是镶嵌治疗成功的关键,超声科医生与外科医生的合作是手术成功的基础。

  • Efficacy of Early Surgery for Infective Endocarditis: A Meta-analysis

    ObjectiveTo systematically review the short term and long term efficacy of early surgery for infective endocarditis (IE) patients. MethodsWe searched PubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI databases for cohort studies concerning the efficacy of early surgery for IE patients from inception to October 2014. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. ResultsSixteen cohort studies including 8 141 patients were included. The results of meta-analysis showed that early surgery could reduce the short term mortality (OR=0.57, 95%CI 0.42 to 0.77, P=0.000 4) and long term mortality (OR=0.57, 95%CI 0.43 to 0.77, P=0.000 7) in IE patients. Subgroup analysis showed that early surgery could significantly reduce the short term mortality and long term mortality in patients with native valve endocarditis (NVE). ConclusionEarly surgery can reduce IE patients' short term mortality and long term mortality. Due to the limited quality and quantity of the included studies, more large-scale high-quality studies are needed to verify the above conclusion.

  • Research progress on risk factors for acute aortic dissection complicated with acute lung injury

    Acute lung injury is one of the common and serious complications of acute aortic dissection, and it greatly affects the recovery of patients. Old age, overweight, hypoxemia, smoking history, hypotension, extensive involvement of dissection and pleural effusion are possible risk factors for the acute lung injury before operation. In addition, deep hypothermia circulatory arrest and blood product infusion can further aggravate the acute lung injury during operation. In this paper, researches on risk factors, prediction model, prevention and treatment of acute aortic dissection with acute lung injury were reviewed, in order to provide assistance for clinical diagnosis and treatment.

  • Prognosis of acute gastrointestinal injury in patients early after acute type A aortic dissection repair and the Nomogram prediction model development

    Objective To analyze the risk factors and prognosis of acute gastrointestinal injury (AGI) early after acute type A aortic dissection (ATAAD) repair, and develop the Nomogram prediction model of AGI. Methods The patients who underwent ATAAD cardiopulmonary bypass surgery in our hospital from 2016 to 2021 were collected and divided into an AGI group and a non-AGI group. The clinical data of the two groups were compared. A Nomogram prediction model was established by using R language. Results A total of 188 patients were enrolled, including 166 males and 22 females, aged 22-70 (49.70±9.96) years. Through multivariate logistic regression analysis, the aortic dissection (AD) risk score, poor perfusion of superior mesenteric artery (SMA), duration of aortic occlusion and intraoperative infusion of red blood cells were the predictors for AGI (P<0.05). There were statistical differences in the ventilator-assisted duration, ICU stay time, liver dysfunction, renal insufficiency, parenteral nutrition, nosocomial infection and death within 30 days after the operation between the two groups (P<0.05). The Nomogram prediction model was established by using the prediction factors, and the C index was 0.888. Through internal verification, the C index was 0.848. The receiver operating characteristic curve was used to evaluate the discrimination of the model, and the area under the curve was 0.888. Conclusion The AD risk score after ATAAD, poor perfusion of SMA, duration of aortic occlusion and intraoperative infusion of red blood cells are independent predictors for AGI. The Nomogram model has good prediction ability.
