前列腺素E1对尸体肾移植术后肾功能延迟恢复的影响

目的探讨前列腺素E1(PGE1)应用于尸体肾移植术后肾功能延迟恢复(DGF)患者对移植肾功能恢复的影响.方法回顾性分析因急性排斥(AR)和急性肾小管坏死(ANT)导致DGF的127例临床资料,其中应用PGE1治疗56例(PGE1组),未用PGE1者71例(对照组).比较两组在出现DGF后的透析治疗时间、肾功能恢复情况、彩超的移植肾血流阻力指数(RI)及6个月内AR发生率.结果与对照组比较,PGE1组透析治疗时间明显缩短(P＜0.05),移植肾的血肌酐下降速度快(P＜0.05),RI及6个月内AR发生率低(P＜0.05).结论PGE1有利于尸体肾移植术后DGF患者移植肾功能的早期恢复,并能降低AR的发生率.

Paired kidney analysis of tacrolimus and cyclosporine microemulsion-based therapy in Chinese cadaveric renal transplant recipients

Few studies used paired kidneys for comparison between tacrolimus and cyclosporine in renal transplantation. Most of the published data used whole blood trough levels for drug monitoring. However, the use of limited sampling strategy and abbreviated formula to estimate the 12-h area under concentration-time curve (AUC(0-12)) allowed better prediction of drug exposure. Sixty-six first cadaveric renal transplant recipients receiving paired kidneys were randomized to receive either tacrolimus-based (n = 33) or cyclosporine microemulsion (Neoral)-based therapies (n = 33). Abbreviated AUC(0-12) was used for drug monitoring and dose titration. Mean follow-up duration was 2.8 +/- 2 years. The patient and graft survival were comparable. Fewer incidence of acute rejection was observed in tacrolimus group (15% vs. 27.3%) though the difference was not significant (P = 0.23). The absolute value and the rate of decline of creatinine clearance were both significantly better in tacrolimus-treated patients. Prevalence of hypertension, post-transplant diabetes mellitus, infection, and malignancy were similar in both groups. Prevalence of hypercholesterolemia (11/33 vs. 4/33) and gum hypertrophy (6/33 vs. 1/33) was more common in cyclosporine-treated patients (P = 0.04 in both parameters). This was the first prospective, randomized study with paired kidney analysis showing the renal function was significantly better in tacrolimus-treated patients than in cyclosporine-treated patients.     

介入法制作犬颅内动脉瘤模型

目的运用介入方法建立犬颅内动脉分叉部囊状动脉瘤模型。方法6条犬全麻后，采用血管内介入方法，用冠状动脉球囊导管扩张右颈总动脉近段，再用可脱球囊于扩张段远端将其栓塞，制作成6个分叉部动脉瘤。分别于术后1、2、3d行DSA检查并切除动脉瘤做病理组织学检查。结果6条犬成功获得6个动脉瘤模型。动脉瘤的平均宽度和平均长度在3d内逐渐减少。结论犬动脉瘤模型较好地模拟了人颅内动脉瘤大小、形态及DSA表现，可用于介入治疗新材料、新技术的实验研究。本动脉瘤模型的建立快速、可靠、可重复性强。
