简介:观察氩氦刀冻融的肺癌细胞联合IL-2对正常人外周血单个核细胞免疫功能的作用.分离正常人外周血单个核细胞,分别与氩氦冻融的肺癌细胞、IL-2和氩氦冻融的肺癌细胞联合IL-2混合培养,并设空白对照组.分别在第3、7、14天检测培养上清液中IL-12含量及NK细胞、CTL细胞的杀伤活性.结果表明,单用氩氦冻融的肺癌细胞可以轻度增加IL-12含量,但不能增加NK细胞、CTL细胞的杀伤活性;氩氦冻融的肺癌细胞联合IL-2后,可明显提高NK细胞和CTL的杀瘤活性.氩氦冻融的肺癌细胞联合IL-2对增强NK细胞和CTL活性具有协同作用,此种作用可能是通过刺激IL-12分泌增加实现的.

简介:目的应用血管超声回声跟踪技术(ET)观察2型糖尿病(T2DM)患者血管内皮功能的相关因素。方法T2DM患者,符合1999年世界卫生组织(WHO)制定的糖尿病诊断标准,共37例,其中男性19例,女性18例;年龄41-68岁,平均年龄64.50岁。应用ET检测患者颈动脉参数,包括血管的压力-应变弹性系数(Ep)、硬化参数(β)及顺应性(AC)、脉搏波传导速度(PWVβ)、增大指数(AI),分析其与病程、年龄、体质量指数(BMI)、糖化血红蛋白(HbA1c)、胰岛素抵抗指数(IR)及合并症的相关性。结果病程与Ep、β、PWVβ呈显著正相关(P〈0.01),与AC呈显著负相关(P〈0.01),与AI无相关性;年龄与β呈正相关(P〈0.05),与Ep、AC、PWVβ、AI均无相关性;是否合并有高血压与Ep、β、AC、PWVβ、AI均无相关性;HbA1c、IR及BMI与Ep、β、AC、PWVβ、AI均无相关性。结论T2DM患者的血管内皮功能主要与病程相关,年龄因素在内皮功能变化中也起到一定作用,血管内皮功能损伤之后,即使良好控制血糖也难以将其逆转。

简介:脊柱融合是治疗脊柱结核、感染、畸形、椎间盘退行性病变脊柱疾患的有效手段,促进脊柱融合成骨率的方法之一就是使用自体骨移植,但其存在来源有限、取骨处疼痛等弊端,目前人重组骨形态发生蛋白-2(Theroleofrecombinanthumanbonemorphogenetic2,rhBMP-2)负载于载体是一种理想的自体骨移植材料的替代物,广泛应用于脊柱融合术中,但近来发现了与其相关的一些副反应。本文就其在脊柱融合中的应用的安全性、有效性及相关的副反应进行综述。
简介:目的通过观察人工股骨头置换术治疗A2型高龄股骨粗隆间粉碎性骨折的疗效,探讨A2型高龄股骨粗隆间粉碎性骨折的治疗策略。方法自1999年1月~2010年4月对23例A2型高龄粗隆间骨折采用人工股骨头置换术,男8例,女15例,年龄75~99岁,平均年龄78.5岁。按AO分型:A2.1型8例,A2.2型12例,A2.3型3例。致伤原因:跌伤19例,车祸伤4例。观察手术时间、术中出血、术后卧床时间及治疗效果并采用Harris评分进行评定。结果23例高龄病人均安全度过围手术期,其中1人术后3个月死于癫痫。22例随访8~18月,平均12月,术后8个月Harris评分,优17例,良3例,可2例,差0例,优良率91%。结论人工股骨头置换术治疗A2型骨折能达到即刻稳定的目的,可满足肢体早期负重活动,具有操作简单、手术时间短、出血量少等优点,对于高龄患者的治疗是一种好的选择。

简介:目的确定在兔子的椎间盘内注射重组人骨形态发生蛋白-2(recombinanthumanbonemorphogeneticprotein-2,rhBMP-2)诱导椎体间融合的可行性。方法将24只成年新西兰大白兔,随机分为2组,每组12只。用微量注样器将含有rhBMP-2200μg的生理盐水溶液20μl和等量的生理盐水分别注射到成年新西兰大白兔的L4~5椎间盘的髓核内。术后10、30、60及90天进行X线照相和组织学检查。结果注射椎间盘未见免疫排斥反应。实验组可见纤维环和软骨终板成骨并在相邻椎体间形成骨桥。对照组的椎间盘内未见骨形成。结论利用注射的方法,rhBMP-2可诱导椎间盘成骨,达到椎体间融合的目的。
