Efficacy and Feasibility of Allogeneic Hematopoietic Stem-Cell Transplantation in the Treatment of Refractory Acute Myeloid Leukemia

Background

Refractory acute myeloid leukemia (AML) includes AML includes failure of disease to respond to standard induction chemotherapy, relapse within 6 months after first CR, and 2 or more relapses. The outcome of these patients is usually very poor; only a small proportion can be rescued by allogenic hematopoietic stem-cell transplantation (allo-HSCT). The aim of this study was to evaluate the efficacy and feasibility of allo-HSCT in patients with refractory AML.

完全型雄激素不敏感综合征2例临床特点及处理

雄激素不敏感综合征(androgen insensitivity syndrome,AIS)又称为睾丸女性化综合征(testicular feminization syndrome,TFS),是一种X连锁遗传病,是男性假两性畸形中较常见的类型,可分为完全型AIS和不完全型AIS,其原因主要是雄激素受体(androgen receptor,AR)基因的突变导致其对雄激素产生抵抗和不应答。本文回顾南京医科大学附属妇产医院2例CAIS患者的临床资料及诊疗过程,以期能进一步提高对该病的认知及诊治水平。     

Voluntary ambulation using voluntary upper limb muscle activity and Hybrid Assistive Limb® (HAL®) in a patient with complete paraplegia due to chronic spinal cord injury: A case report

Context: We sought to describe our experience with the Hybrid Assistive Limb® (HAL®) for active knee extension and voluntary ambulation with remaining muscle activity in a patient with complete paraplegia after spinal cord injury.

Findings: A 30-year-old man with complete paraplegia used the HAL® for 1 month (10 sessions) using his remaining muscle activity, including hip flexor and upper limb activity. Electromyography was used to evaluate muscle activity of the gluteus maximus, tensor fascia lata, quadriceps femoris, and hamstring muscles in synchronization with the Vicon motion capture system. A HAL® session included a knee extension session with the hip flexor and voluntary gait with upper limb activity. After using the HAL® for one month, the patient’s manual muscle hip flexor scores improved from 1/5 to 2/5 for the right and from 2/5 to 3/5 for the left knee, and from 0/5 to 1/5 for the extension of both knees.

Conclusion/clinical relevance: Knee extension sessions with HAL®, and hip flexor and upper-limb-triggered HAL® ambulation seem a safe and feasible option in a patient with complete paraplegia due to spinal cord injury.     

完全性左束支传导阻滞伴快速心房纤颤并急性左心衰竭的抢救

目的总结完全性左束支传导阻滞伴快速心房纤颤并急性左心衰竭的治疗经验,以提高抢救成功率.方法对经抢救治疗的完全性左束支传导阻滞伴快速心房纤颤并急性左心衰竭9例(16次)患者进行治疗方面的回顾分析.结果9例(16次)患者14次抢救成功,成功率87.0%,但复发率较高,预后较差,有5例患者在抢救时或出院后1～2年内猝死.结论该组患者经传统"强心、利尿、扩血管",控制心房纤颤、心室率等治疗是远远不够的.应在未发生肺泡性肺水肿及心源性休克之前,尽早尽快地应用血管扩张剂及联合应用小剂量非洋地黄类正性肌力药物,并维持治疗24～72 h.其中以酚妥拉明加多巴胺和(或)多巴酚丁胺效果可能较佳,血管扩张剂硝酸酯类不及α-受体阻滞剂酚妥拉明疗效明显.     

固定桥桥体龈底形态对接触区黏膜微生态影响的研究

目的探讨烤瓷桥桥体龈端不同形态设计对牙槽嵴顶黏膜微生态的影响。方法对60例磨牙烤瓷修复的患者采用常规细菌培养和计算机鉴定的方法进行检测。结果桥体龈端接触区细菌附着量和种类与牙体预备前相比,均有增多。其中,改良鞍式和改良盖嵴式桥体龈端接触区细菌附着量和细菌种类变化的差异有统计学意义(P<0.05);而舟底式桥体龈端接触区细菌附着数量和种类的变化,均无统计学意义(P>0.05)。戴用3个月后,各组链球菌和奈瑟菌的组成比例变化与牙体预备前相比,差异有统计学意义(P<0.05);其余各类细菌组成比例的变化无统计学意义(P>0.05)。结论从对桥体底黏膜微生态的影响考虑,烤瓷桥舟底式桥体优于改良鞍式和改良盖嵴式桥体,是值得临床推广应用的磨牙桥体设计。     

Changes in the basal ganglia and thalamus following reperfusion after complete cerebral ischaemia

We report specific changes bilaterally in the basal ganglia and thalamus following reperfusion after complete cerebral ischaemia. A 69-year-old man, resuscitated after cardiac arrest, showed symmetrical lowdensity lesions in the head of the caudate nucleus and lentiform nucleus on CT. MRI revealed methaemoglobin derived from minor haemorrhage in the basal ganglia and thalamus, not evident on CT. We suggest that this haemorrhage results from diapedesis of red blood cells through the damaged capillary endothelium following reperfusion.     

Paralysis of the axillary nerve with Complete compensation – a case report

Summary Two patients with complete paralysis of the axillary nerve are reported on. One case is well documented. In both cases there was very good functional adaptation, resulting from hypertrophy of the rotator cuff so that there was only a slight or no loss of movement. The rotator cuff should therefore be exercised at an early stage when there is isolated axillary nerve damage. The function of the supraspinous muscle is also discussed.      

带塑料插入件栓式附着体义齿修复后满意度的调查

目的 通过问卷调查表对患者戴用附着体义齿后的主观感受进行研究.方法 选择上下牙列缺损患者42例,共制作带塑料插入件栓式附着体义齿47例,于戴牙后1个月,患者基本适应戴用义齿,通过问卷调查,了解患者戴用义齿后的适应情况、对义齿的满意程度及咀嚼功能的变化等.结果 患者对带塑料插入件栓式附着体义齿和传统可摘局部义齿两种修复方式比较,在总的满意度、美观、舒适、咀嚼、语言、适应期、食物结构改变等方面,前者明显优于后者,差异有统计学意义.结论 带塑料插入件栓式附着体义齿在美观及功能上不仅能满足患者的要求,而且远优于传统可摘局部义齿.     

静脉动脉化再植拇指完全离断

目的 报道静脉动脉化再植拇指完全离断的新方法。方法 1999—2002年在5例拇指完全离断再植手术中，因指动脉严重损伤或多次吻合指动脉失败后，将近侧动脉与断指的一条静脉吻合作为供血通路，近侧的静脉与断指的另几条静脉吻合作为回血通路。结果 5例再植拇指全部成活，早期病例完全恢复了良好的功能。结论 静脉动脉化是一种拇指离断再植的新方法，操作简便，效果可靠，值得推广应用。
