气相色谱用于肠通透性监测的研究

作者采用国产气相色谱及９２０２微机数据处理系统，对临床患者和实验动物肠通透性改变进行监测。该方法以甘露醇（Ｍ）和乳果糖（Ｌ）为探针，用气相色谱检测尿中糖分泌率及Ｌ／Ｍ比值。结果显示，测定标准品Ｍ和Ｌ随进样量增加而呈线性改变，与国外学者报道一致。比较不同浓度进口与国产乳果糖，证明二者在研究肠通透性方面高度相关（ｒ＝０．９９）。检测急性胰腺炎并发感染动物的尿标本，发现乳果糖大量排出，Ｌ／Ｍ值明显增加。作者认为，气相色谱为一行之有效的方法用于肠通透性监测，有助于临床上对内源性感染及脓毒症的早期诊断。     

Thigh pain and multiple vertebral osteonecroses: value of magnetic resonance imaging.

We describe a 74-year-old woman who presented with referred thigh pain associated with multiple osteonecroses of the T12, L1 and L2 vertebrae. Magnetic resonance imaging was found to be a valuable diagnostic aid, revealing signs of spinal cord and nerve root compression related to the collapsed vertebrae. Biopsy of T12 confirmed the benign nature of the vertebral compression fracture. Our patient also showed histologically documented osteoporosis.     

Treatment of hemophilia A by living mother-to-son splenic transplantation. First case report in the world.

A case of severe hemophilia A was treated by living mother-to-son splenic transplantation. The recipient was a 9-year-old boy. After splenic transplantation, the level of blood factor VIII:C was increased, and no spontaneous hemorrhage occurred. The boy was followed up for over two years. This is a case of spleen allotransplantation with the longest function in the world.
