超声心动图监测评价红花注射液对冠心病患者左室舒张功能的影响

目的:应用超声心动图观察红花注射液对冠心病心肌缺血患者左室舒张功能的影响。方法:随机将76例冠心病心肌缺血患者分为2组,其中38例在常规药物基础上加用红花注射液治疗为红花组,其他38例应用常规药物治疗为常规治疗组,2组均连续用药14天,对心肌缺血及心功能的相关指标作对比观察。用药前后采用常规超声心电图联合组织多普勒显像(TDI)对左室舒张功能进行检测。结果:治疗后ST段压低的次数及其持续时间与心肌缺血总负荷2组均有明显减少,与治疗前比较,有非常显著性差异(P0.01),2组疗效比较,红花组优于常规治疗组(P0.01)。红花组左室舒张功能指标(E、A、E/A、DC、Ea、Aa、Ea/Aa、E/Ea)明显改善(P0.01),常规治疗组治疗前后差异无统计学意义(P0.05)。用药期间,患者无严重不良反应。结论:红花注射液对冠心病心肌缺血有显著疗效,且能改善左室舒张功能。     

Long-term effects of neovaginal reconstruction with sigmoid loop technique on sexual function and self image in patients with gynecologic malignancies: results of a prospective study

ObjectiveWe evaluated the long-term results of sigmoid vaginoplasty in women with gynecologic malignancies after radical pelvic surgery, with specific focus on safety and effects of the procedure on patients' sexuality and self image.MethodsThis prospective study included women with gynecologic malignancies who underwent partial or complete colpectomy as part of the cancer treatment. In all cases a pedicled sigmoid loop was used for the neovaginal reconstruction. Systematic clinical examination was performed and validated questionnaires about sexuality (Female Sexual Function Index), quality of life (SF-12) and susceptibility to depression (ADSk-15) were answered by all patients at the earliest 6 months after vaginoplasty.ResultsSeven patients with sigmoid vaginoplasty, recruited between 11/2003 and 02/2008, were evaluated in the present analysis. Mean patients age was 48 ± 8.49 years. Mean neovaginal length was 6.4 cm (range: 2–12 cm). The mean Female Sexual Function Index (FSFI)-score of all patients was 16.6 ± 12.6. In the subset of sexually active patients the mean FSFI-score was 22.5 ± 9.4 higher. Regarding early operative morbidity and complications, sigmoid vaginal reconstruction appears to be a safe procedure, though in a long-term assessment 85% of the patients developed a vaginal stenosis with the need for operative bougienage.ConclusionsThe vaginal reconstruction using a sigmoid loop is a safe and well accepted procedure in patients with gynecologic malignancies. However lower sexuality scores seem to be achieved than in non-cancer patients after equivalent vaginoplasty. Cancer-related physical and psychological comorbidity seem to have negative effects on the overall outcome and patient's satisfaction.     

The ‘beating-heart butterfly technique’ for repair of basal post-infarction ventricle septum defect

Ischaemic ventricular septal defect is a serious complication of acute myocardial infarction with poor outcome. We present the ‘beating-heart butterfly’ technique to close the ventricular septal defect with a double-layered pericardial patch sewn to the intact septum under beating-heart cardiopulmonary bypass in 4 highest-risk patients. This technique combined with a liberal postoperative mechanical circulatory support and open-chest treatment allowed excellent results with 12 months of survival in all patients.     

泛素蛋白酶体途径在高氧肺损伤发病机制中的研究进展

泛素蛋白酶体途径是生物中特异的蛋白质降解系统之一。它参与体内许多重要的生理过程,临床中许多疾病的发生都与该途径的激活有关。高氧将产生氧自由基,引起细胞损伤、凋亡、坏死,同时引起炎性介质产生、炎性细胞浸润,从而产生肺部炎性反应、组织损伤和异常修复发生。本文将探讨泛素蛋白酶体途径的组成、功能及其在高氧肺损伤发病机制的作用。     

甘露醇治疗急性脑出血对肾功能影响的动态观察

本文观察了22例用甘露醇治疗急性脑出血的患者。对治疗前、治疗后、停药后的肾功能（BuN．Cr）进行动态监测，结果为治疗后肾功能有不同程度的损害，老年人较中年人更易发生肾功能损害，停药后绝大部分恢复正常。提示：甘露醇对肾功能的损害是可逆的。     

探讨食道超声在防治房颤患者脑卒中的应用价值

目的：分析111例行食道超声和头颅CT检查的房颤患者,了解左房血栓与脑卒中的关系以及食道超声在防治房颤患者脑卒中的应用价值。方法：通过对2006年3月～2008年8月在新疆自治区人民医院心内科住院的房颤患者,行食道超声和头颅CT检查并对住院病例进行回顾性分析,了解左房血栓的发生率,以及左房血栓与脑卒中发生的关系。结果：111例房颤患者均经食道超声检查,发现左房血栓15例,占13.5%。左房血栓组与左房无血栓组在脑卒中发生率方面有统计学意义（X2=10.695P〈0.001）。结论：左房血栓与脑卒中的发生密切相关,食道超声在防治房颤患者脑卒中的方面有重要的应用价值,建议为预防房颤患者脑卒中的发生,对房颤患者行食道超声检查。

目的 探讨经导管射频消融治疗特发性室性心动过速及频发室性期前收缩的疗效及安全性.方法 141例特发室性心动过速及频发室性期前收缩患者(男80例,女61例)采用激动顺序标测和(或)起搏标测方法行导管射频消融治疗.结果 消融成功128例,成功率为90.8%,起源于右室流出道的室性心动过速或室性期前收缩消融成功率为92.0%.20例患者行消融前后的Hoher检查,术前平均(21 824±12 769)次/24 h,术后平均(1 548±2 926)次/24 h,二者间差异有统计学意义(P<0.001).随访3～36个月,10例复发并全部再次消融成功.无并发症发生.结论 导管射频消融治疗症状严重且药物治疗无效的特发性室性心动过速或频发室性期前收缩是安全、有效、可行的方法.     

多平面经食道超声心动图估测左心耳功能及血栓的评价

目的 评价应用经食道超声心动图(TEE)估测左心耳功能及诊断左房血栓的价值。方法 采用TEE对33例伴有或不伴有房颤患者检测左心耳容量及收缩功能，探测左房和左心耳内有无明确血栓征象。并与经胸多普勒二维超声心动图(TTE)比较。结果 33例患者中左房血栓6例，左心耳血栓6例，排除左房血栓3例。根据左心耳面积测定计算出左心耳射血分数(Efv)与左心耳峰值血流排空速度(Per)相关性良好(r=0．84)。结论 TEE不仅可定性诊断左房血栓，还可测量左心耳射血分数，房颤患者左心耳面积扩大，左心耳射血分数减低，评价左心耳功能较二维超声心动图更为准确。

Evolution of thrombolytic therapy in patients with HeartWare ventricular assist device thrombosis: a single-institutional experience

Open in a separate window OBJECTIVESPump thrombosis remains a major challenge in heart failure patients with left ventricular HeartWare assist device. Current International Society for Heart and Lung Transplantation recommendations favour surgical pump exchange over lysis because safety and efficacy of lysis has been controversially reported. This study summarizes our experience on our HeartWare thrombosis prevention strategy as well as thrombolysis through implementation of our institutional standardized HeartWare assist device protocol.METHODSOutcomes of all HeartWare thrombosis patients admitted between 2010 and 2020 were analysed. Thrombolysis therapy using tissue plasminogen activator was used as the first-line therapy in this study and thrombolysis therapy efficacy was defined as freedom from stroke, bleeding, recurrent HeartWare assist device thrombosis or surgical device exchange within 30 days after lysis application.RESULTSA total of 507 patients have been included in this study and 66 patients (13%) collectively developed a first HeartWare-thrombosis after a median of 12 months (8–22 months) after HeartWare implantation. Forty patients were treated with unstandardized lysis, of whom 7 patients had thrombolysis associated complications, such as incomplete thrombus resolution requiring surgical pump exchange in 4 patients, but also intracranial haemorrhage occurring in 3 patients. Three patients died in the non-protocol group. Eight device thrombosis patients were treated according to our protocol, showing no lysis-associated complication.CONCLUSIONSDespite current recommendations, preferring surgical HeartWare pump exchange in thrombosis, thrombolysis therapy for first HeartWare thrombosis can be safe and effective in a standardized protocol setting, including anticoagulation adjustment and intensified blood pressure control management.
