Objective To investigate the effects of high dose ambroxol on patients with acute lung injury（ALI） after liver transplantation.Methods Thirty patients with ALI after liver transplantation were divided randomly into an ambroxol group and a control group.On the base of routine treatment，the patients were treated by intravenous infusion with high dose ambroxol of 15 mg/kg once a day for 7 days in the ambroxol group and with normal saline of same volume in the control group.The arterial blood gas analysis was performed and IL-1，IL-10 and TNF-α were measured before and 1 day，3 day and 7 day after the treatment.Length of stay in ICU were recorded and death rate in one year were followed-up.Results After the 1 days，3 days and 7 days of treatment，PaO2 and PaO2/FiO2 were improved in both groups with more significant improvement in the ambroxol group（Plt;0.05）.Before treatment，no differences of IL-1，IL-10 and TNF-α level were found between the two groups.But the level of IL-1 and TNF-α decreased significantly in the ambroxol group compared with the control group after 1 day treatment，and no differences were found after 3 day and 7 day.The level of IL-10 increased in both groups，but significantly in the ambroxol group after 1 day.The lenght of ICU stay in the ambroxol group was shorter than that in the control group[（8.2±5.6）d vs（11.4±6.5）d，Plt;0.05].Two died in the ambroxol group and 3 in the control group with no significant difference.Conclusion High dose ambroxol can improve blood gas exchange and decrease the lenght of ICU stay in ALI patients after liver transplantation，through its inhibitory effects on inflammatory response by down-regulation of IL-1，TNF-α and up-regulation of IL-10.
目的 通过比较三种血液净化方式对炎症介质、甲状旁腺激素等中大分子毒素的清除效果，并观察促红细胞生成素（EPO）的治疗效果，探寻有利于肾性贫血改善的最佳透析模式。 方法 2011年5月－8月采用前瞻性、随机对照、开放式设计，选择维持性血透患者60例，随机分成3组，每组20例。血液灌流（HDP）组[每2周5次血液透析（HD）+1次HDP]、血液透析滤过治疗（HDF）组（每2周5次HD+1次HDF）、HD组（每2周6次HD），随访3个月。检测试验前后反应蛋白（CRP）、β2微球蛋白、甲状旁腺素（PTH）、白介素-6的水平以及各组患者肾性贫血指标的变化。 结果 3个月试验结束时，HDP组和HDF组4项尿毒症毒素水平均显著下降，其中HDP组CRP水平明显低于HDF组（P＜0.05）；HDP组和HDF组试验后的血红蛋白水平较试验前升高，ERI值下降。HD组试验前后的毒素水平无明显变化，ERI值升高。3组患者均未出现严重不良事件。 结论 HDP和HDF清除中大分子毒素的能力优于HD，有利于缓解微炎症状态，改善EPO治疗效果。HDP和HDF的远期效果哪种更好，尚有待于进一步的研究。
目的:研究罗格列酮(ROS)治疗2型糖尿病,对患者组织胰岛素敏感性与血清炎症介质改变的关系。方法:选取符合1999年WHO标准确诊的2型糖尿病患者30例。试验采用前后自身配对方法。口服ROS 4mg每天一次,总疗程8周。测定指标包括常规临床检查项目、血糖,同时检测血浆胰岛素水平,糖化血红蛋白(HbA1c)水平、C反应蛋白(CRP)、白细胞介素6(IL-6)、肿瘤坏死因子-α(TNF-α)水平,以 HOMA模型和胰岛素钳夹试验评价组织胰岛素敏感性。结果:应用ROS治疗的2型糖尿病患者组织胰岛素敏感性显著改善(Plt;0.05),并降低血浆CRP、IL-6、TNF-α水平,这些炎症介质的改变与组织胰岛素敏感性的改变相关。结论:应用ROS治疗2型糖尿病能降低患者血浆炎症介质水平,减轻胰岛素抵抗,延缓或减轻糖尿病大血管并发症的发生发展。
