Abstract: The cyanotic congenital heart defect remains a focal point to study in congenital heart diseases. A successfully developed model of cyanotic congenital heart defect can contribute to a profound advancement of clinical diagnosis and treatment. Various kinds of animal models simulating cyanotic heart diseases have been created and improved step by step , such as experimental pulmonary arteriovenous fistulas, inferior vena cava-left atrium shunt, pulmonary artery-left atrium shunt and breeding animals in mionect ic environment. As an important means, they are used to investigate the animal’s pathophysilolgocal characteristics in cyanotic and hypoxic state. However, it need a further exploration since these models are not fully perfect yet.
Abstract: Quality of life (QOL) refers to an individual’s perception and subjective evaluation of their health and well-being, and has become an important index to evaluate the outcomes of clinical treatment in the last past decades. There are a large number of different instruments to evaluate QOL, and the 36-Item Short Form Health Survey (SF-36) is currently one of the most widely used instruments. In recent years, SF-36 has been used to evaluate QOL of valvular heart disease patients to investigate the risk factors those influence their postoperative QOL, provide more preoperative evaluation tools for clinical physicians, and improve postoperative outcomes of patients with valvular heart disease. However, it is now just the beginning to use SF-36 to examine QOL of valvular heart disease patients. Because of significant differences in sample size, follow-up period, country and culture, current research has some controversial results. This review focuses on the progress in evaluating QOL in postoperative patients with valvular heart disease using SF-36.
目的 总结单心室瓣膜反流的外科治疗经验,观察治疗效果。 方法 回顾性分析2006年7月至2012年1月上海交通大学医学院附属新华医院61例单心室患者的临床资料,其中男36例,女25例;手术年龄2个月至 20岁;体重2~58 kg。右心室型41例,左心室型13例,未定型型7例。根据瓣膜反流程度不同分为3组,无/微量反流组:28例,瓣膜未行处理;轻/中度反流组:21例,瓣膜未行处理;重度反流组:12例,手术同期行瓣膜成形。收集所有患者住院及随访资料,分析轻/中度反流组、重度反流组瓣膜反流变化趋势,以及影响瓣膜反流的因素。结果 住院死亡5例,住院死亡率8.2% (5/61)。重度反流组患者行瓣膜成形术后反流程度较术前明显减轻(由术前4.00级下降至术后2.08级)。随访56例,随访时间6~38个月,重度反流组随访10例,随访期间死亡2例,其余8例中重度反流2例,中度反流3例,轻度反流2例,微量反流1例;瓣膜反流程度增加趋势明显(由术后平均2.08级增加至平均2.75级)。轻/中度反流组随访19例,随访中无死亡,其中反流程度增加至重度3例(原1例轻度反流,2例中度反流),反流程度由轻度增加至中度3例,瓣膜反流程度由术后平均2.33级增加为平均2.58级。轻/中度反流组瓣膜反流增加率与无/轻微反流组比较差异无统计学意义(瓣膜反流增加率为31.5% vs. 19.2%,χ2=0.36,P=0.55)。单因素分析结果显示,瓣膜反流增加者在随访过程中心功能较瓣膜反流无变化或减轻者明显降低(术后左心室射血分数53.11%±5.61% vs. 59.65%±3.32%,t =-5.49,P=0.00),而左心室舒张期末容积较瓣膜反流无变化或减轻者明显增加(t =2.58,P=0.01)。 结论 单心室合并重度瓣膜反流行瓣膜成形术近期效果较好,但随着心功能下降、心室扩张,瓣膜反流程度加重趋势明显;轻/中度瓣膜反流可暂不进行处理,但部分患者瓣膜反流有增加趋势,提示应注重术后随访。
The application of stem cell therapy for ischemic heart disease has aroused widespread interest. There have been many experimental studies concerning a variety of tissue stem cells such as bone marrow,blood,skin and skeletalmuscle stem cells,and their origins, differentiation and protein expressions are compared. In recent years,it is found that adipose-derived stromal cells (ADSCs) have potential advantages over other types of stem cells in that they are widely available and easily harvested through a simple liposuction procedure,and have a high regenerative capacity and therapeuticpotential for myocardial infarction. This review describes molecular and biological properties of ADSCs,their differentiationpotential,and regenerative and therapeutic potential for myocardial repair.
Bloodless surgery is a comprehensive and systematic perioperative treatment approach in order to avoid allogeneic transfusion for surgery,improve patient prognosis,and relieve blood shortage. Bloodless heart surgery indicates some perioperative strategies to avoid allogeneic transfusion and improve clinical outcomes,which involves participation of cardiac surgeons and other professionals during cardiac surgery. For years,many cardiac surgeons have utilized several blood management and conservation techniques during open heart surgery to avoid allogeneic transfusion. Research results from major medical centers indicate that bloodless heart surgery can shorten postoperative recovery period and improve patientprognosis. In this review,we describe basic theory and systematic methods of bloodless surgery,and summarize applicationprogress of bloodless heart surgery and current status in China.
Abstract: Objective To construct an Anticoagulation Therapy Database of Chinese Patients after Heart Valve Replacement in accordance with blood coagulation characteristics of Chinese patients, fill the gap of Chinese clinical research in valvular heart diseases, and provide a scientific and objective basic data and information exchange platform. Methods A national multicentre,prospective and cohort clinical research method was applied to establish an anticoagulation therapy database of Chinese patients after heart valve replacement, using the Internet as a platform. A case report form (CRF), which was in line with the actual situation of Chinese anticoagulation patients after heart valve surgery, was formulated through the discussion of experts from 36 cardiovascular surgery centers in China in the starting meeting of National Science amp; Technology Support Program during the Twelfth Five-year Plan Period.We planned to prospectively include patients receiving warfarin anticoagulation therapy and formal anticoagulation monitoring after heart valve replacement from January 1, 2011 to December 31, 2014. Database was constructed using warehousing technology, which allowed not only data monitoring, query and statistics, but also regular data backup and system updates. Results A network database entitled Anticoagulant Therapy Database of Chinese Patients after Heart Valve Replacement was constructed and linked with the homepage of Chinese Journal of Clinical Thoracic and Cardiovascular Surgery (http://www. zgxxwkzz. com), which constituted a national Internet information platform. From 1 January 2011 to 1 December 2012, 8 452 anticoagulation patients after heart valve replacement from 34 level-3A hospitals in China had been registered in the database. Further follow-up of these patients was being carried out in respective hospitals. Conclusion A large multi-center and open database and network information platform has been constructed. The database variables are in line with clinical characteristics of Chinese anticoagulation patients after heart valve replacement, which provide scientific and objective basic data and support for future clinical research and systemic analysis.
Objective To evaluate outcomes of vacuum sealing drainage(VSD)for the treatment of wound infection after cardiac surgery.?Methods?We retrospectively analyzed clinical data of 70 patients(with valvular heart disease,congenital heart disease or coronary heart disease)who underwent cardiac surgery via mid-sternotomy and had postoperative wound infection from Jan. 2008 to Jan. 2012 in General Military Hospital of Guangzhou Command. According to different treatment strategy for wound infection, all the patients with wound infection (incision longer than 5 cm) were randomly divided into VSD group (n=35) and control group(n=35) by random number table,while VSD treatment was used for patients in VSD group and routine treatment was used for patients in control group. Treatment outcome,duration of wound infection, duration of antibiotic treatment and treatment cost were compared between the two groups.?Results?There was no in-hospital death in both groups. Wound exudate significantly decreased and fresh granulation tissue grew well in the wound in most VSD group patients after VSD treatment. The cure rate of VSD group was significantly higher than that of control group (94.3% vs. 60.0%,P<0.05). Duration of wound infection (12.9±3.4 d vs. 14.8±4.1 d;t=-2.094,P=0.040)and duration of antibiotic treatment (7.0±1.5 d vs. 8.3±1.9 d;t=-2.920,P=0.005) of VSD group were significantly shorter than those of control group. There was no statistical difference in treatment cost between the two groups. Fifteen patients in VSD group were followed up (42.9%) for 3 months with good wound healing, and 20 patients in VSD group were lost in follow-up.?Conclusion?VSD is effective for the treatment of wound infection after cardiac surgery with shortened treatment duration and similar treatment cost compared with routine treatment.
Abstract: Objective To evaluate the protective effects of Ulinastatin on the peri-operative liver and renal function in patients undergoing cardiac surgery for tetralogy of Fallot (TO F). Methods Thirty-eight patients with TOF were divided into Ulinastatin group and control group according to admission sequence, 19 cases in each group.For Ulinastatin group, intravenous Ulinastatin was given with a dosage of 10 000U /kg at 1h before operation, 1h and 24 h after operation. For control group, no Ulinastatin was given. 10 ml fresh urine and 2 ml blood samples were collected before operation, and postoperative 1h, 10h, 24h, 48h and 72h, respect ively. The liver and renal functions were measured. Fluid intake, urine output, chest drainage, dosage of furosemide, durations of mechanical ventilation and intensive care unit ( ICU ) stay were recorded. Results Neither arrhythmia nor low cardiac output syndrome occurred for both groups. No peri-operative death. Compared with control group, dose of furosemide, period of mechanical ventilation were lower, while urine output was higher in Ulinastat in group; the aberrant climax value of urine pro tein and N-acetylglucosam inidase (NAG) were lower in Ulinastatin group (10h post-operat ively, urinem icroalbum in: 65. 2 ± 58. 3mg/L vs. 71. 8 ±58. 9mg/L ; urine transferrin: 5. 8 ± 3. 6mg/L vs. 7. 4 ± 5. 4mg/L ; urine immunoglobulin G: 26. 9±20. 3mg/L vs. 31. 3±23. 3mg/L ; 1h post-operat ively; urine NAG: 61. 4±81. 6U /L vs. 76.1±48. 5 U /L ; P lt; 0. 05) and maintained in shorter period (P lt; 0. 05) , it returned to baseline value at 48h and 72 h post-operatively. The value of alanine aminotransferase (ALT) significantly increased post-operatively at every time points in control group (P lt; 0. 01) , w hile no obvious change in Ulinastat in group (P gt; 0. 05). The increased value of aspartate aminotransferase (AST ) in Ulinastatin group was significantly lower than that in control group (10h post-operat ively: 144. 4±20. 8U /L vs. 202. 7±74. 1U /L ; P lt; 0. 01). The value of AST returned to baseline value at 48h and 72h post-operat ively. Conclusion U linastatin is an effect ive strategy for protecting peri-operat ive liver and renal function of the patients with tetralogy of Fallot and the clinical application of Ulinastatin is safe and effective.
