Effect of “Re Du Qing” on the activation,proliferation and membrane fluidity of lymphocytes

Summary Effects of Chinese Medicinal Preparation “Re Du Qing” (RDQ) on the activation, proliferation and membrane fluidity of T lymphocytes from human peripheral blood Were studied by means of³H-TdR incorporation and DPH fluorescence polarization. The results showed that “RDQ” can:1) significantly inhibit the activation of T lymphocytes; 2) restrain the proliferation of activated T lymphoblasts in the presence of exogenous interleukin-2 (IL-2); and 3) increase the membrane fluidity of T lymphocytes and antagonize the decreased fluidity of lymphocyte membrane mediated by Con A or PHA. The functional abnormalities of T lymphocytes in some autoimmune diseases such as arthritis and the usefulness of RDQ in the treatment of these diseases were also discussed.

珊瑚型人工髋关节置换术的临床随访及松动原因的分析

自１９８３年至今应用珊瑚型人工髋关节置换术共５４例６０髋。其中人工全髋关节置换术３４例４０髋，人工股骨头置换术２０例２０髋。在５４例６０髋珊瑚型人工髋关节置换术中，有３７髋随访６个月～１３年，平均随访时间约７年，疗效满意率为８５．１％，其中假体松动４例占１４．８％，髋臼松动２例７．４％。假体松动原因是假体与股骨负重界面之间没有达到稳定接触，假体与髓腔形状不相匹配，修整髓腔松质骨时，髓腔扩大器应比假体小一号，避免假体与界面存留缝隙。对于髋臼发育不良的患者应避免髋关节旋转中心向外侧移位，应向内上方加深髋臼以减少水平移位距离，其次髋臼植骨加盖勿在负重区。     

原发全身性癫痫遗传流行病学研究

本文报道１００例原发全身性癫痫家系的遗传流行病学研究结果。先证者一级亲属患病率为６．８６％，二级亲属为１．０３％；分别是对照组一级亲属的１３．８３倍和２．０８倍。原发全身性癫痫的遗传度为：一级亲属０．７５２１±０．０６７８，二级亲属０．３５９２±０．０７４６；加权平均０．５７４３±０．０５０２。说明遗传因素起重要作用。发病年龄影响因素分析表明：原发全身性癫痫有一定年龄依从性。ＥＥＧ家系分析显示，该型癫痫一级亲属癫痫样放电明显高于对照组一级亲属，提示癫痫样放电的遗传倾向。     

The clearance of a single i.v. bolus of recombinant human erythropoietin from the serum of patients with myelodysplastic syndromes and its effects on erythropoiesis.

The serum erythropoietin (EPO) concentration in patients with myelodysplasia (MDS) varies widely at similar hemoglobin concentrations, although the reasons for this variation are unclear. We have studied the pharmacokinetics of an i.v. bolus of recombinant human EPO in ten subjects with myelodysplasia. Basal serum EPO concentration varied from 210 to 5984 mU/ml. Plasma half-time clearance (t1/2) varied from 3.9 to 20.0 h. A significant positive correlation was found between t1/2 and basal EPO concentration. An increase in immature peripheral blood reticulocytes was found on days 1 and 2 after EPO treatment; this may represent either an effect on hemopoiesis or on reticulocyte release from the bone marrow.     

距骨的血液供应及其临床意义

本文观察了２４侧尸体足标本，均无已知临床血管疾病。在死后３６～４８小时之间行动脉灌注ＡＢＳ填充剂，以化学腐蚀和手工剔除的方法清除软组织。距骨的血供来自小腿下部三根主要动脉的分支，即跗骨管动脉和三角支、近端和远端跗骨窦动脉、颈上支及后结节血管丛。跗骨管动脉常发自足底内侧动脉，而三角支多单独自胫后动脉发出；跗骨管动脉通常比三角支和跗骨窦动脉都来得细小。以上的这些动脉相互吻合，形成了一个骨膜血管网，覆盖于全部的距骨非关节面上。而且，环绕着跗骨管、跗骨窦、距骨颈的上面和距骨体部的内侧面，由三角支、跗骨管动脉、跗骨窦动脉、颈上支及其相互之间的吻合血管网形成了一个不定形的距骨动脉环。本文还讨论了距骨缺血性坏死与动脉环的可能关系，距骨骨折脱位或手术后的缺血性坏死是由于距骨动脉环的毁损或功能受影响所致。三角支在距骨骨折脱位时具有重要意义，手术或手法复位时应注意保护。     

荞麦花粉抗贫血作用的实验研究

用荞麦花粉的水提取液进行了抗大白鼠缺铁性贫血的研究，结果表明：荞麦花粉具有和硫酸亚铁相似的抗缺铁性贫血作用．饮用荞麦花粉提取液３５ｄ的大白鼠，生长发育良好，主要脏器未见损害．该研究为荞麦花粉的开发利用提供了实验依据．     

肝尾叶切除

肝尾叶深藏于肝门结构与下腔静脉之间，具有独立的管道系统，手术切除风险较大，作者结合２例肝尾叶切除的体会，复习文献，对肝尾叶的解剖、影像学特征、切除指征及手术方法进行了讨论。     

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.

     

血浆纤维连接蛋白含量对肺性脑病预后判断的临床价值

采用火箭电泳法对６４例（８０例次）肺性病患者进行血浆纤维连接蛋白（Ｆｎ）测定。合并肺性脑病１９例，并与１０６例健康人及１０４例其他呼吸疾患进行对比．结果表明：正常组、肺性病缓解组、急性发作组、肺性脑病组血浆Ｆｎ水平分别为３４．２７±６．３６ｍｇ／ｄｌ，２９．６１±４．２５ｍｓ／ｄｌ，１５．２１±５．２０ｍｇ／ｄｌ，１１．８２±５．６７ｍｇ／ｄｌ．肺性脑病患者血浆Ｆｎ显著降低，并随病情恶化而进一步下降。同时，其含量变化与ｐＨ值和ＰａＯ２呈正相关，与ＰａＣＯ２，呈负相关。因此动态观察肺性脑病患者血浆Ｆｎ含量可作为判断顶后一项较为可靠的指标。
