  • Relationship between Platelet and Prognosis of the Total Correction of Tetralogy of Fallot

    ObjectiveTo explore the relationship between platelet and prognosis of the total correction of tetralogy of Fallot (TOF). MethodsWe included 11 dead patients with TOF at age of 0-6 years as a death group between 2011 and 2014 year. There were 7 male and 4 female patients at age of 18.6±16.4 months in the death group. We selected 11 matched survival patients according to age, gender of the patients as a survival group. There were also 7 male and 4 female patients at age of 19.4±16.7 months in the death group. The patients were divided into a high-platelet group and a low-platelet group. There were 6 male and 5 female patients in the high-platelet group. While there were 8 male and 3 female patients in the low-platelet group. Inflammatory cytokine and mortality were compared between the two groups. ResultsPost-operative count of platelet in the death group was significantly lower than that in the live group, while post-operative interleukin-6 (IL-6) and C reactive protein (CRP) were much higher than those in the death group (P<0.05). Mortality was higher in the low-platelet group than that in the high-platelet group (P<0.05). ConclusionPlatelets may alleviate inflammatory response and reduce mortality, which played a great role of protection.

  • 体外循环相关急性肾损伤与干细胞治疗研究进展

    体外循环(extracorporeal circulation,ECC)是心脏直视手术不可或缺的辅助及治疗手段。但同时,ECC 带来的全身炎症反应及多器官损伤也给临床提出了挑战。急性肾损伤(acute kidney injury,AKI)是 ECC 术后主要的并发症及死亡原因之一,不仅增加住院时间和住院费用,还明显增加术后患者的病死率,极大地威胁着临床患者的预后。然而,目前国内外针对 ECC 相关 AKI 的治疗手段十分有限,主要集中于围手术期药物使用及肾替代治疗等对症支持治疗两个方面。尽管目前的治疗大多集中于 AKI 的损伤期,内源性细胞修复及以细胞为基础的治疗方案受到越来越多的重视。最新的研究发现干细胞在ECC相关肾损伤的修复过程中发挥着重要的作用。该文对 ECC 相关 AKI 与干细胞治疗研究进展进行了综述。

  • Dupilumab injection in the treatment of moderate to severe atopic dermatitis in adults: a cost-effectiveness analysis

    ObjectiveTo evaluate the economics of duplizumab in combination with optimal supportive care versus optimal supportive care for moderate-to-severe atopic dermatitis in adults from the perspective of our health system. MethodsA Markov model embedded in a decision tree was constructed to compare the long-term cost-utility of dupilumab combined with optimal supportive care versus optimal supportive care, and a sensitivity analysis was performed on the results. ResultsThe results of the basic analysis showed that compared with the optimal supportive care, dupliyuzumab in combination with optimal supportive care resulted in 3.82 more QALYs, while its cost was 125 549.42 yuan more. The ICER was 32 854.83 yuan/QALY, which was less than one times China's per capita GDP in 2022, and was economical. Univariate sensitivity analysis showed that factors such as Dupilumab-16-week post - no response utility value, Dupilumab-52-week post response rate and Dupilumab-52-week adherence had a greater impact on the cost changes. The results of the probabilistic sensitivity analysis showed a stable model structure and good robustness. ConclusionIn adult patients with moderate-to-severe atopic dermatitis, dupliyuzumab in combination with an optimal supportive care regimen is more cost-effective compared to an optimal supportive care regimen.

  • Surgical Treatment of Tetralogy of Fallot with Anomalous Coronary Artery

    Abstract: Objective To summarize the experience of surgical treatment of tetralogy of Fallot (TOF) with anomalous coronary artery. Methods From March 1993 to April 2006, 22 patients with TOF and anomalous coronary artery underwent repair. The resection of hypertrophied parietal, septal band and the ventricular septal defect (VSD) repairs were performed by trans-right ventricular outflow tract (RVOT) approach in 5 cases, and by transatrial approach in 17 cases, which consisted of 7 cases required a transannular patch to enlarge a pulmonary annulus, construction of a double barrel outlet in 6 cases, by autologous pericardium conduit (3 cases), homograft (1 case) and reflected anterior wall of the main pulmonary artery in combination with bovine pericardium (2 cases). Results There was one operative death because of the anomalous coronary artery impairment. The accessory left anterior descending artery was severed because it was mistaken for the conal arteryin 1 case, which caused failure to wean from bypass, after the left internal mammary artery was anastomosed to the accessory left anterior descending artery, the cardiopulmonary bypass (CPB) was stopped successfully. Mean early gradient(ΔP) was 23.4mmHg and ΔP>20mmHg in 9 cases. Eighteen cases were followed up, mean time was 13.2 months. Late ΔP>20mmHg in 7 cases, and ΔP were less than 20mmHg in 11 cases. Conclusion The repair of TOF with anomalous coronary artery is more safe by using the transatrial approach. The surgical reconstruction of RVOT depends on the anatomic characteristic of anomalous coronary artery.

  • Research progress on surgical evaluation system for congenital heart disease

    The surgical difficulty of congenital heart disease varies greatly. To ensure the safety of surgery and maximize the benefits of patients, various congenital heart surgery scoring systems have been used to evaluate the risk of different complex congenital cardiac operations. However, the complete correction of cardiac anatomical malformations is a common surgical challenge. Recent studies have shown that the correction is closely related to perioperative mortality and postoperative complications, and a new scoring system for the degree of cardiac anatomical malformations has been proposed. Therefore, this review summarizes the literature and discusses different evaluative methods of congenital heart surgery, aiming to optimize the surgical evaluation system for congenital heart surgery, enhance the quality of surgery and improve the prognosis of patients.

  • The Effect of Up-regulating CXCR4 Expression on Bone Marrow Neutrophils in Modulating its ECC-related Rapid Release

    ObjectiveBased on the rat in situ perfusion system, to explore the effect of up-regulating Chemokine (C-X-C motif) receptor 4 (CXCR4) expression on bone marrow neutrophils in modulating its ECC-related rapid release. MethodsTwelve SD rats were randomly divided into fucoidan perfusion group (F, n=6) and control group (C, n=6) after in situ perfusion system establishment. Rats in F group received perfusion of fucoidan solution (total volume 6 ml, 1 h) and C group received buffer only. Femurs from two groups were dissected after one-hour perfusion and bone marrow tissues were collected. The neutrophil CXCR4 expression in two groups were compared using flowcytometry. Eighteen SD rats were randomly divided into fucoidan perfusion group (F', n=6), fucoidan and AMD-3100 perfusion group (F+AMD3100, n=6) and control group (C', n=6) after in situ perfusion system establishment. Rats received desired interventions before stimulation from ECC plasma. After that, 40-min perfusions of buffer were added and total counts of neutrophil in perfusates were compared. ResultsThe percentages of CXCR4 (+) cell and CXCR4 expression fluorescence in F group were 4.71%±0.21% and 161.3±7.8 respectively while the values were 1.11%±0.11% and 58.4±6.5 respectively in C group. Values in F group were both significantly higher than those in C group (P<0.05). The total counts of neutrophil in perfusates from F' group, F+AMD3100 and C' group were 261 393.7±12 470.6, 872 635.2±10 430.6 and 818 675.2±10 708.8, respectively. Statistically differences were observed between each other (P<0.05). ConclusionBone marrow neutrophil CXCR4 expression of SD rat could be effectively up-regulated by perfusion of fucoidan within the in situ perfusion system. ECC-plasma-stimulated bone marrow neutrophil release in rat could be inhibited by fucoidan induced up-regulation of neutrophil CXCR4 expression, and this inhibition effect could be canceled by AMD-3100 intervention.

  • Per-ventricular Device Closure of Doubly Committed Sub-arterial Ventricular Septal Defect ——Technical Consideration and Perioperative Management

    Doubly committed sub-arterial ventricular septal defect (VSD) is a unique type of VSD which is located beneath both the aortic and pulmonary valve. Open-heart repair is traumatic especially for pediatric patient while trans-catheter device closure is also not suitable for this type of VSD. Minimally invasive per-ventricular device closure has been introduced as an alternative method in the treatment of doubly committed VSD with encouraging results. In the review, we will illustrate the surgical technique as well as perioperative management strategy as for this technique in treating doubly committed VSD.

  • Surgical Treatment of Tetralogy of Fallot: A Report of 164 Cases

    Objective To sum up the therapeutic results of corrective surgery of 164 cases of tetralogy of Fallot (TOF), and explore the optimal time and risk factors of operation,as well as perioperative management. Methods One hundred and sixty-four consecutive cases of TOF underwent corrective surgery. There were simple stenosis of infundibular portion in right ventricular outflow tract in 37 cases, stenosis of infundibulum and pulmonary valve in 14 cases, main pulmonary trunk and left/right pulmonary arteries stenosis in 113 cases, and pulmonary atresia in 5 cases. Autologous pericardial conduit, valved homograft were used for right ventriculo-pulmonary artery connection, respectively. Other anomalies were corrected. Results The surgical mortality was 3.66% (6/164). The cause of death were serious low cardiac output syndrome(2 case), fail to wean from cardiopulmonary bypass after coronary artery bypass grafting (1 case), ventricular arrhythmia(1 case) and postoperative acute respiratory distress syndrome (2 cases). Conclusion It’s necessary to perform corrective operation on younger TOF patients. Low cardiac output syndrome is not the key reason of leading to postoperative complications or death. Preventing remnant obstruction of pulmonary artery and pulmonary complication should be focused during and after operation.
