RGD肽表面修饰壳聚糖载基因纳米粒子的体外实验研究

目的 将Arg-Gly-Asp(RGD)肽偶联到壳聚糖(cH)材料表面,并制备成包载质粒DNA的纳米粒子,以未偶连RGD的壳聚糖载质粒DNA作为对照,进行体外内皮细胞转染,观察其是否能提高对内皮细胞的转染效率.方法 以1-乙基-3-(3-二甲基氨基丙基)碳化二亚胺盐酸盐(EDC)和N-羟基丁二酰亚胺(NHS)为偶联剂,通过酰胺键将RGD肽偶联到壳聚糖表面,对其进行表征,并以未偶连RGD的壳聚糖作为对照,制备载pEGFP-C1质粒DNA纳米粒子,比较2者对Hy926细胞的转染效率.结果 壳聚糖-RGD(CH-RGD)载基因纳米粒子转染Hy926细胞的效率明显高于未偶连RGD的壳聚糖载基因纳米粒子(35.7%vs 14.3%,P<0.001).结论 RGD肽表面修饰壳聚糖载基因纳米粒子可用于体外细胞转染,其对细胞的转染效率明显优于未偶连RGD的壳聚糖.

COMBINED INTRAOPERATIVE ILIAC ARTERY STENTS AND FEMORO-POPLITEAL BYPASS FOR MULTILEVEL ATHEROSCLEROTIC OCCLUSIVE DISEASE

Objective. To review our preliminary experience and evaluate our early results of a combined intraopemtive iliac angioplasty and stenting with infrainguinal revascularization in multilevel atherosclerotic occlusive disease. Methods. From July 1999 to April 2000, intraoperative iliac angiOplasty and stenting combined with simultaneous femoro-pepliteal bypass were pedormed on 12 lower extremities of 10 patients suffering from multilevel athemsclemtic occlusive disease. There were 8 men and 2 women, average 72 years. The indicationsf or procedures included disabling claudication in 3 and rest pain in 7 patients. Results. Eleven iliac angioplasty and stem procedures combined with simultaneous 9 femoro-popliteal by-pass and 3 femoro-femoral-popliteal bypass were performed in 12 limbs of 10 patients. Angioplasty and stem placement was technically successful in all patients. One contralateral femoral-popliteal bypass was failure after femoro-femoral-popliteal bypass. There were no additional instances of procedural or postoperative morbidity or mortality. Mean follow-up was 5 months (range 1 -10 months). During the follow-up period, one femoro-infrapoplitealgraft became occluded after 7 months and above-knee amputation was required. The cumulative primary patencyrate of stented iliac arteries, femoro-femoral bypass grafts and femoro-popliteal bypass grafts were 100% (11/11), 100% (3/3) and 90. 9% (10/11) in the follow-up period, respectivdy. The amputation rate was 8. 3%(1/12). Conclusions. Intraoperative iliac artery PTA and stent placement can be safely and effectively pedormed simultaneously with infrainguinal revascularization for multilevel atherosclerotic occlusive disease by skilled vascular surgeon, using a portable C ann fluoroscopy in the operating room. Furthermore, iliac artery PTA and stenting was valuable adjunct to distal bypass either to improve inflow and outflow, or to reduce the extent of traditionalsurgical intervention, and also, any angioplasty and stenting-related complications can be immediately corrected as well.     

小心跌入类风湿关节炎的治疗误区

类风湿关节炎是以累及周围关节为主的多系统炎症性自身免疫病,其特征为对称性、周围性多个关节慢性炎性病变,临床表现为受累关节疼痛、肿胀、功能下降,病变呈持续、反复发作过程。由于风湿病专业在我国起步较晚,大量类风湿关节炎由非本专业医务人员诊治,出现了一些诊疗误区。     

卡维地洛在老年充血性心力衰竭治疗中的应用

目的观察卡维地洛治疗老年充血性心力衰竭(心衰,CHF)的疗效和安全性。方法选择老年CHF患者45例,随机分为心衰常规治疗组(22例)和卡维地洛治疗组(23例),后者在常规抗心衰治疗基础上加用卡维地洛,从小剂量开始,渐增至最大耐受量,疗程6个月。两组治疗前和治疗3、6个月末使用超声心动图分别测定左心室舒张末期内径(LVEDD)、左心室收缩末期内径(LVESD)和左心室射血分数(LVEF),并观察6min步行距离,记录不良反应。结果老年CHF患者用卡维地洛治疗后,LVEDD、LVESD和LVEF的改善均优于常规治疗组(P<0.01),6min步行距离增加较常规治疗组更为显著(P<0.01)。治疗期间无严重不良反应出现。结论在心衰常规治疗基础上加用卡维地洛治疗老年心衰患者耐受量虽偏小,但可明显改善心功能,提高运动耐量,缩小心室,改善左室重构。

目的观察注射用重组人脑利钠肽(rh BNP)治疗需要接受机械通气的重度急性左心衰(SALHF)的临床疗效。方法将51例需要接受机械通气的重度急性左心衰患者随机分为治疗组和对照组,两组均给予机械通气及对症支持治疗,治疗组在此基础上加用rh BNP。结果治疗组72 h后BNP、机械通气时间、住ICU时间、总住院时间、气管插管率、住院病死率显著低于对照组(P均0.05)。两组不良反应对比差异无统计学意义(P0.05)。结论早期合理使用rh BNP治疗SALHF疗效确切,具有良好的安全性,可持续改善临床症状,缩短机械通气时间和住院时间,降低气管插管率和住院病死率。     

冠状动脉慢血流现象的临床意义

目的:探讨冠状动脉慢血流现象的临床及近期预后价值。方法:通过矫正的TIMI血流分级方法,评价冠状动脉血流速度和远端血流灌注。对37例正常血流者和35例无冠状动脉狭窄性病变而冠状动脉慢血流者行次级量平板运动试验及心脏超声左室射血分数(LVEF)测定,并随访1年,观察近期预后。结果:冠状动脉慢血流组平板运动试验阳性率明显高于正常血流组(71.4%∶13.5%,P<0.01),而平板运动耐量时间明显低于正常血流组[(5.32±4.38)∶(10.58±5.67)min,P<0.01)];2组LVEF差异无统计学意义;随访1年发现冠状动脉慢血流组中10例反复心绞痛发作、1例发生急性下壁心肌梗死,无心脏性猝死发生。结论:冠状动脉慢血流现象与运动耐量降低、心绞痛发作有关,应引起临床重视。
