超声心动图监测经导管心脏间隔缺损关闭术

应用超声心动图监测，经导管关闭先天性心脏间隔缺损９例。术中监测的主要内容有：（１）确定关闭器在心内的位置；（２）显示残余分流和瓣膜返流；（３）观察房间隔缺损球囊探测的过程。结果表明：超声心动图在显示心内结构、关闭器位置，残余分流和瓣膜流等方面有其独特性，同时可结合声学造影或术中需要进行多方面的监测。     

Retardation of pain development: a case of recovery from congenital insensitivity to pain

Congenital analgesia is a rare genetic disorder. We report here that a 12-year-old boy was able to recover from congenital insensitivity to pain. Neurological examinations revealed that there was a 'stocking' distribution of pain decrement on the lower extremities under the patient's knee joints. Magnetic Resonance Imaging (MRI) of his brain showed gyrus thinning with sulcus widening at both sides of the parietal lobe. Southern blot hybridization probed with cDNAs of various opioid receptors did not detect any significant abnormality. Our results suggest that this rare case may not be genetically determined.     

长跑运动对老年人尺桡骨密度影响的观察

本文对63名老年长跑运动员及非运动老年人的尺桡骨骨密度进行了测定。结果表明,男性运动组尺、桡骨骨密度及风桡骨骨密度均值比非运动组显著升高,男性运动年限>10年组桡骨骨密度、尺桡骨骨密度均值明显高于运动年限≤10年组,而女性运动组尺桡骨骨密度及尺桡骨骨密度均值与非运动组相比无明显差异。提示,坚持长跑锻炼在预防老年性骨质疏松症中,对男性作用明显,而对女性作用不显著。     

肝豆状核变性患者血清Ⅲ型前胶原肽测定的临床价值

本文用放射免疫分析法测定了38例HLD患者血清Ⅲ型前胶原肽(PⅢP)的含量,其均值为18.34±12.42ng/ml,较正常对照组7.49±0.81ng/ml明显增高,经青霉胺治疗后的部分轻症患者血清PⅢP水平可恢复正常。认为HLD患者血清PⅢP的检测为反映肝纤维化活动性、程度及肝细胞炎症、坏死的灵敏指标,定期监测对肝硬化的趋势及药物疗效的评估均具有临床价值。     

生长激素在肝硬变门脉高压低蛋白血症手术前的应用研究

目的：研究生长激素（rhGH)对肝硬变门脉高压低蛋白血症患者手术前的治疗价值。方法：肝硬变门脉高压抑行脾切除、门奇静脉断流手术患者60例，Child分级B级，随机分为rhGH治疗组30例，对照组30例。rhGH组术前5d每天皮下注射rhGH 4IU，对照组给予安慰剂生理盐水。两组术前均行相同肠外营养支持。测定治疗前、治疗后3d、4d、5d血浆白蛋白、球蛋白、前白蛋白及空腹血糖。结果：rhGH组治疗后3d前白蛋白较治疗前及对照组明显升高（P＜0．05），治疗后4d、5d仍维持较高水平；治疗后5d白蛋白较治疗前及对照组明显升高（P＜0．05）。rhGH组患者一般情况改善，生活质量提高。对照组白蛋白、前白蛋白无明显变化。两组空腹血糖、球蛋白无明显改变。结论：rhGH联合肠外营养支持对纪正肝硬变门脉高压低蛋白血症患者术前低蛋白状态，改善生活质量有良好疗效，由于rhGH起效慢，应早期、足量、足疗程应用。     

Educating the Public About Stroke

Acute stroke affects large numbers of people worldwide. It causes significant morbidity and mortality. Data support the hypothesis that the public is not familiar with either the risk factors or the signs of stroke. Educating the public about stroke may result in a lower incidence of the disease as individuals modify their risk factors, and in improved outcomes as a result of reductions in delays to treatment. There is clear and convincing evidence that reducing delays to treatment of patients with acute stroke results in improved outcomes. Public education programs should be broad-based, tailored to individual audiences, and carry a common theme.     

氧化作用与子宫内膜异位症

子宫内膜异位症是育龄妇女的常见疾病 ,近年来其发病率有上升趋势 ,研究认为EM发生发展与腹腔氧化作用有关。氧化作用是一种炎症反应 ,EM中巨噬细胞释放的氧化活性物 ,腹腔液中氧化低密度脂蛋白及其产物的增加 ,子宫内膜细胞氧化酶与抗氧化酶的异常表达 ,腹腔液中VitE的消耗 ,均说明EM与腹腔氧化作用有关。本文综述有关研究结果为用抗氧化剂和抗炎症制剂预防EM发生提供新的研究途径     

Recombinant human stem cell factor stimulates growth of a human glioblastoma cell line expressing c-kit protooncogene.

The growth of a panel of eight different human glioblastoma cell lines was examined in a human tumor cloning assay in agar, a tritiated thymidine uptake assay, and by counting cell numbers, in cultures performed in the absence or presence of increasing concentrations (1 to 100 ng/ml) of recombinant human stem cell factor (SCF). Growth of 7 of 8 cell lines was not significantly and reproducibly affected by recombinant human SCF. However, growth of the CRL 1620 cell line could be stimulated up to 5-fold by the cytokine. In contrast to the other cell lines investigated, CRL 1620 expressed the c-kit protooncogene assessed on the mRNA and protein level. Furthermore, SCF-induced proliferation of CRL 1620 cells was sensitive to the tyrosine kinase inhibitor erbstatin. Our data suggest that SCF can be operative in growth modulation of malignant cells outside the hematopoietic system, and this finding should be further studied for its possible clinical implications.
