Giant right atrium and subvalvular pulmonary stenosis: A case report of an interesting combination

A 20‐year‐old Congolese woman presented with presyncope, dyspnea, and anasarca. Past medical history was unremarkable. Echocardiography revealed a rare combination of giant right atrium (RA), a dilated and hypertrophied right ventricle, subvalvular pulmonary stenosis (subPS), severe tricuspid regurgitation (TR), pericardial effusion and what appeared to be a spontaneously closed ventricular septal defect (VSD). Cardiac Magnetic Resonance and Cardiac Computed Tomography confirmed the findings excluding the presence of intra‐cardiac and extra‐cardiac shunt and other associated congenital anomalies. The patient underwent subPS resection, right atrioplasty, and tricuspid annuloplasty. Multimodality approach facilitated the detection of the abnormalities and provided clarity when determining the optimal surgical strategy.     

严重胸腹部闭合性联合伤致呼吸心跳停止成功救治1例

报告1例严重胸腹部闭合性联合伤所致的急性呼吸心跳骤停得到成功救治的病例。闭合性胸腹联合伤后,因病情可能发展,应随时注意复查胸片、血气等;若基层医院条件不够,应及时转往上级医院,以免延误患者的治疗。     

闭合性脑外伤患者恢复后期的记忆研究

目的探讨闭合性脑外伤患者恢复后期的记忆障碍特点。方法用临床记忆量表对 2 0例闭合性脑外伤患者恢复后期及 2 0例正常人进行记忆测验。结果闭合性脑外伤患者恢复后期 5项分测验及记忆商均明显低于正常人对照组 ,MQ≤ 79的比例较正常人明显增高。结论闭合性脑外伤患者恢复后期有非常严重的记忆障碍 ,其回忆比再认受损更严重     

胰腺闭合性损伤的外科诊治探讨

目的探讨胰腺闭合性损伤诊断和外科处理的方法。方法分析20例胰腺闭合性损伤的诊断，手术处理和预后。结果17例治愈，死亡3例，死亡率15，并发胰瘘2例，假性囊肿2例，腹腔脓肿1例。结论CT、B超及血淀粉酶检查对胰腺损伤仍具有一定的诊断价值。术中关键是保持警觉，按胰腺损伤情况选择适当的术式。     

干细胞动员对骨创伤大鼠免疫功能的保护作用

目的：观察自体干细胞动员对骨创伤大鼠的免疫功能的保护作用，为战创伤后的免疫抑制及继发性感染、系统性炎症反应等治疗提供依据。方法：挤压折断法复制大鼠双后肢股骨骨折模型，于致伤后0、24、48h连续给模型动物肌肉注射GM—CSF20μg／kg，致伤后72h细胞增殖法检测T、B淋巴细胞活性，ELISA法检测血清IL-1、IL-2、IFN-7、TNF—α浓度，自动系列化分析法检测C3、CA、IgM、IgG浓度，称重法观察脾重与体重的比例变化。结果：股骨骨折模型大鼠致伤后72h，GM—CSF动员骨髓干细胞组大鼠的T、B淋巴细胞活性和血清IFN-γ、IL-2浓度高于对照组（P〈0．01），IL-1、TNF—α浓度低于对照组（P〈0．01），血清C3、CA、IgM、IgG浓度及脾／体重比值高于对照组（P〈0．01）。结论：GM—CSF动员自体干细胞动员对大鼠骨创伤诱导的免疫功能抑制具有保护作用。     

24例骨折术后深部感染的原因及对策

目的 探讨骨折术后深部感染的原因、预防和治疗方法。方法 对骨折术后深部感染病灶行扩创后置管闭合灌洗。结果 24例经清创闭合灌洗平均27．5d后，感染均得以控制，效果满意。结论 骨折手术后深部感染原因是多方面的，宜积极预防，早期发现，及时扩创闭合灌洗，遗留肢体功能障碍者留待后期治疗。     

An alternative method of nitrous oxide delivery into a minimal-flow circle breathing system

We have sought to define a way in which nitrous oxide can be safely and universally used at minimal to low flows by utilising a circle system with a controlled leak provided by a standard gas analyser sampling line and a fresh gas supply of 50% nitrous oxide in oxygen, entering from a trunk interposed between the ventilator and the circle system. Although preliminary calculations suggested that this arrangement was likely to work, it was found that 13 of 23 patients studied prospectively developed an inspired oxygen fraction below 0.3. We conclude that, although this arrangement provides a new means of introducing nitrous oxide into the circle breathing system, it does not appear inherently safer or more convenient than the conventional route.     

闭合性轻度脑外伤事件相关电位地形图的初步研究

为了解脑外伤后病人精神心理和智力改变的客观依据,我们使用DantecConcerto~(TM)仪,对24例闭合性轻度脑外伤患者和14例正常人P_(300)分布地形图的变化进行了对比观察。结果发现正常组P_(300)高波幅区相对集中于Cz附近的椭园形区域内,而脑外伤组则从Cz向两侧颞后播散,潜伏期延长,波形分化不良,波幅反而较正常组高;重复试验时,正常组潜伏期略为缩短,波幅稍增高,分布更集中于Cz为中心的小范围内,而脑外伤组向整个后头部移动,潜伏期进一步延长,波幅普遍明显下降,唯有T_3点反而奇异地升高38％。作者认为以上改变可能是参与P_(300)发生的皮层和皮层下结构中的微细结构受损害而使其整合功能被削弱的结果。这一结果与认为P_(300)发生于大脑皮层及皮层下各结构的综合反应的观点是一致的。     

A recycling framework for the construction of Bonferroni‐based multiple tests

In this paper we describe Bonferroni‐based multiple testing procedures (MTPs) as strategies to split and recycle test mass. Here, ‘test mass’ refers to (parts of) the nominal level α at which the family‐wise error rate is controlled. Briefly, test mass is split between different null hypotheses, and whenever a null hypothesis is rejected, the part of α allocated to it may be recycled to the testing of other hypotheses. These recycling MTPs are closed testing procedures based on raw p‐values associated with testing the individual null hypotheses, and the class of such MTPs includes, for example, serial and parallel gatekeeping, fallback and Holm procedures. Graphical displays and a concise algebraic notation are provided for such MTPs. This recycling approach has pedagogical advantages and may facilitate the tailoring of MTPs for different purposes.
