慢性肝炎辨治五法

慢性肝炎（简称慢肝）属中医学“胁痛”、“黄疽”、“瘾积”等范畴。其病程长，疗效慢，且易反复发作。目前尚无特殊疗法。笔者通过研习有关文献，回顾长期临床验案，对慢性肝炎之证治略有心得，兹介绍如下。     

输精管结扎干扰前列腺增生过程的机制探讨——精浆睾酮双氢睾酮的放射免疫测定

本文应用放射免疫测定的方法检测了13例输精管结扎后(平均15.3年,平均年龄50岁)的男性精浆双氢睾酮和睾酮的浓度,另取同年龄组男性13例作为对照。结果表明,精浆睾酮在结扎组(374.54p/ml)和正常对照组(315.64Pg/ml)中没有明显差异,而结扎组精浆中双氢睾酮(46.21pg/ml)却明显低子对照组(184.27pg/ml(p<0.01)。作者认为,输精管结扎对精浆DHT有长期影响,这可能是其对前列腺增生过程产生抑制作用的原因之一。     

超声热疗临床应用的研究

目的：通过超声热疗配合常规放疗治疗晚期恶性肿瘤的临床研究，评价超声热疗的疗效及与疗效有关的加热参数。材料和方法： 对１７ 例晚期恶性肿瘤的１７ 个病灶用常规放疗加超声热疗。放疗用直线加速器外照射，每次２ Ｇｙ、周５ 次， 总剂量４０～７０ Ｇｙ。热疗在放疗后３０ ｍ ｉｎ 内进行，每周加热１～２ 次，每次加温时间 ６０ ｍ ｉｎ，６～８ 次一疗程。全例病人每次加温时实测肿瘤内温度。结果：在可评价的１３例中，ＣＲ ２３．１％ （３／１３）、ＰＲ ４６．２％ （６／１３）、ＮＣ ２３．１％ （３／１３）、ＰＤ ７．７％ （ １／１３） ， 有效率（ＣＲ＋ ＰＲ）为６９．３％ 。肿瘤中心部温度达到４２．５℃以上的累积时间和总加热次数是决定疗效的重要参数。在１７ 例患者的 ８９ 次加温中，副作用的发生率相对较低。结论：使用超声热疗配合放疗，只要实现满负荷加温，进一步提高肿瘤的局部控制率是完全可能的     

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.

     

Antifibrinolytics in orthotopic liver transplantation: current status and controversies.

This article reviews the current status and controversies of the 3 commonly used antifibrinolytics-epsilon-aminocaproic acid, tranexamic acid and aprotinin-during liver transplantation. There is no general consensus on how, when or which antifibrinolytics should be used in liver transplantation. Although these drugs appear to reduce blood loss and decrease transfusion requirements during liver transplantation, their use is not supported uniformly in clinical trials. Aprotinin has been studied more extensively in clinical trials and appear to offer more advantages compared to two other antifibrinolytics. Because of the diverse population of liver transplant recipients and the potential adverse effects of antifibrinolytics, especially life-threatening thromboembolism, careful patient selection and close monitoring is prudent. Further studies addressing the risks and benefits of antifibrinolytics in the setting of liver transplantation are warranted.     

参附注射液对肠缺血-再灌注大鼠肿瘤坏死因子α的影响

目的观察肿瘤坏死因子α(TNF-α)在大鼠肠缺血-再灌注损伤过程中的作用及参附注射液对TNF-α的影响,探讨参附注射液防治肠缺血-再灌注损伤机制。方法 SD大鼠随机分为肠缺血-再灌注组(IR组)、参附注射液预处理组(SF组)和假手术组(C组)。采用阻断肠系膜上动脉(SMA)的方法制造肠缺血-再灌注模型。分别测定各组动物血浆、肠组织TNF-α含量及血液动力学变化;光镜观察肠粘膜损伤情况。结果IR组再灌注后MAP下降,与C组和SF组比有显著性差异(P<0.01);SF组肠粘膜损伤程度减轻,与IR组比有显著性差异(P<0.01);SF组血浆及肠组织TNF-α水平降低,与IR组比有显著性差异(P<0.01)。结论参附注射液可明显防治大鼠肠缺血-再灌注导致的肠粘膜损伤,这种作用可能是通过抑制TNF-α的释放实现的。
