Congenital Heart Disease in Adolescents With Gluteal Muscle Contracture

Gluteal muscle contracture (GMC), presented with hip abduction and external rotation when crouching, is common in several ethnicities, particularly in Chinese. It remains unclear that the reasons why these children are weak and have no choice to accept repeated intramuscular injection. Here, we found some unique cases which may be useful to explain this question.We describe a series of special GMC patients, who are accompanied with congenital heart disease (CHD). These cases were first observed in preoperative examinations of a patient with atrial septal defect (ASD), which was proved by chest X-ray and cardiac ultrasound. From then on, we gradually identified additional 3 GMC patients with CHD. The original patient with ASD was sent to cardiosurgery department to repair atrial septal first and received arthroscopic surgery later. While the other 3 were cured postoperative of ventricular septal defect (VSD), tetralogy of fallot (TOF), patent ductus arteriosus (PDA), respectively, and had surgery directly.The study gives us 3 proposals: (1) as to CHD children, it is essential to decrease the use of intramuscular injection, (2) paying more attention to cardiac examination especially cardiac ultrasound in perioperative period, and (3) taking 3D-CT to reconstruct gluteal muscles for observing contracture bands clearly in preoperation. However, more larger series of patients are called for to confirm these findings.

大白鼠皮肤Ⅱ度、Ⅲ度碱烧伤模型复制

目的 根据大白鼠皮肤碱烧伤创面早期病理组织学观察复制Ⅱ、Ⅲ度碱烧伤模型,研究碱烧伤的临床治疗.方法 Wistar纯种健康大白鼠20只,以不同浓度2mol/l、2.5mol/l、5mol/lNaOH,作用时间分别为30秒、45秒、60秒、75秒,涂抹于脱毛后的表皮.结果 2mol/L(60s)、2.5mol/L(45s),5mol/L(30s)即可直接造成Ⅱ度～深Ⅱ度烧伤;2mol/L(75s)、2.5mol/L(60s)、5 mol/L(45s)即可造成Ⅲ度烧伤,其烧伤深度与NaOH溶液浓度和作用时间呈正比.结论 Ⅱ度、Ⅲ度碱烧伤均为渐进性烧伤,与文献中介绍的潜拙样损伤似乎不同.另外,不同浓度NaOH溶液在相同时间对皮肤组织的损伤及同一浓度NaOH溶液在不同时间对大白鼠皮肤的损伤病理学变化均有差异.

急诊冠状动脉内支架植入治疗急性心肌梗死——围术期死亡和近期预后的研究

为评价急性心肌梗死(AMI)患者急诊经皮冠状动脉腔内成形(PTCA)和冠状动脉内支架植入围术期死亡和近期预后的影响因素,通过对74例行急诊冠状动脉内支架植入的AMI,术后6个月内的临床随访和冠状动脉造影随访,进行多因素相关回归分析。结果表明,多支病变患者的糖尿病、高血压和高血脂的合并比例明显高于单支病变患者;总围术期内死亡率为5.4％,剔除合并心源性休克患者后,死亡率为1.4％;12例75岁以上的患者中,2例死于心源性休克,1例死于心脏破裂,5例心源性休克患者死亡3例;术中非致命性合并症的发生率在单支和多支病变组之间差异无显著性(P>0.05);多元回归分析表明血流动力学状态和患者的年龄是决定AMI患者围术期死亡的独立相关因素;多支病变患者术后6个月内心脏事件发生率明显高于单支病变组;术前和术后6个月内的患者左心室射血分数(LVEF)明显改善;而且单支和多支病变组之间术后6个月时的LVEF之间无显著性差异。

超声照射对声振微泡稳定性的影响

目的与方法造影剂微泡浓度、大小是影响心肌声学显影最重要因素。本研究采用２×２×４析因分析法分析不同超声照射条件对造影剂微泡浓度及直径的影响,即声波频率、能量以及照射时间对微泡浓度、大小的单独及交互作用。为临床行静脉心肌声学造影检查时选择适宜的超声照射条件提供参考。结果能量越大、照射时间越长,微泡破坏越多,平均直径越小：照射频率对微泡浓度影响不大,但影响微泡大小,频率越高,微泡越小。结论为减少超声照射对微泡的破坏,提高心肌声学造影效果,应尽可能选用低能量、低频率超声波,并减少不必要的照射时间。
