PNH者患红细胞膜结构损伤及膜脂与膜蛋白关系的探索

本文分析了20例PNH患者红细胞膜总脂,Ch/PIM比及磷脂组分,并比较了10例PNH红细胞膜AChE在PBS系统和生理盐水中的酶活性。发现PNH红细胞膜脂缺失严重,比正常少22％,但Ch/PIM比值及各磷脂相对含量均无明显改变。在PBS中AChE活性接近正常红细胞,但在生理盐水中明显低于正常红细胞,仅为正常的40％。表明PNH红细胞对补体敏感而溶血可能是由于补体导致膜脂缺失,进而破坏了红细胞膜结构的完整性而引起的,这也是AChE活性在低pH环境中酶活性比正常红细胞低的原因。     

右心室不同部位起搏血液动力学改变的研究

目的：根据右心室不同部位起搏时血液动力学改变，研究选择置入右心室双部位起搏器辅助治疗心脏扩大合并充血性心力衰竭(CHF)，观察临床效果及心脏功能；方法：对13例在心内科住院的扩张型心肌病、缺血性心肌病、心动过速性心肌病所致心力衰竭的患者，男9侈4，女4侈4，年龄36岁～75岁(平均58．61岁)，心功能均在Ⅲ级～Ⅳ级(NYHA)，均有置入起搏器的适应证。术中通过Swan—ganz漂浮导管对右心室内不同部位起搏10分钟后测各部位的急性血液动力学改变，然后置入右心室双部位起搏器(右室流出道应用主动固定电极)。术后应用心电图、超声心动图观察右心室双部位起搏的血液动力学效果；结果：全组13例患者术中检查及置入右心室双部位起搏器均获成功。测得右心室流出道起搏(RV—OT)和右室心尖部(RVA) 右室流出道(RVOT)起搏时各参数均较单纯右室心尖部(RVA)为好。置入心脏起搏器后观察射血分数从0．31提高至0．39，左室充盈时间延长，二尖瓣返流量减少，心脏缩小，心脏功能平均提高Ⅱ级。其中一例心功能由Ⅳ级提高至I级～Ⅱ级；结论：初步血液动力学观察提示，右心室双部位起搏能改善充血性心力衰竭患者的心功能。

Adult-to-adult living donor liver transplantation using extended right lobe grafts.

OBJECTIVE: The authors report their experience with living donor liver transplantation (LDLT) using extended right lobe grafts for adult patients under high-urgency situations. SUMMARY BACKGROUND DATA: The efficacy of LDLT in the treatment of children has been established. The major limitation of adult-to-adult LDLT is the adequacy of the graft size. A left lobe graft from a relatively small volunteer donor will not meet the metabolic demand of a larger recipient. METHODS: From May 1996 to November 1996, seven LDLTs, using extended right lobe grafts, were performed under high-urgency situations. All recipients were in intensive care units before transplantation with five having acute renal failure, three on mechanical ventilation, and all with hepatic encephalopathy. The median body weight for the donors and recipients was 58 kg (range, 41-84 kg) and 65 kg (range, 53-90 kg), respectively. The body weights of four donors were less than those of the corresponding recipients, and the lowest donor-to-recipient body weight ratio was 0.62:1. The extended right lobe graft was chosen because the left lobe volume was <40% of the ideal liver mass of the recipient. RESULTS: Median blood loss for the donors was 900 mL (range, 700-1600 mL) and hospital stay was 19 days (range, 8-22 days). Homologous blood transfusion was not required. Two donors had complications (one incisional hernia and one bile duct stricture) requiring reoperation after discharge. All were well with normal liver function 5 to 10 months after surgery. The graft weight ranged from 490 g to 1140 g. All grafts showed immediate function with normalization of prothrombin time and recovery of conscious state of the recipients. There was no vascular complication, but six recipients required reoperation. One recipient died of systemic candidiasis 16 days after transplantation and 6 (86%) were alive with the original graft at a median follow-up of 6.5 months (range, 5-10 months). CONCLUSIONS: When performed by a team with experience in hepatectomy and transplantation, LDLT, using an extended right lobe graft, can achieve superior results. The technique extends the success of LDLT from pediatric recipients to adult recipients and opens a new donor pool for adults to receive a timely graft of adequate function.
