胰岛素强化治疗对严重创伤患者炎性反应及预后的影响

Objective To investigate the effects of intensive insulin therapy on inflammatory re-sponse and prognosis of patients with severe trauma. Methods Eighty severely injured patients were di-vided into intensive insulin therapy group (n = 40, IT) and routine therapy group (n = 40, RT) in random pair. At the time of admission, a continuous infusion of insulin (2 -4 U/h) was pumped into the patients of IT group to maintain blood glucose level at 6 -8 mmol/L. Patients in RT group were given routine treatment without administration of insulin. Fever, organ injury, and mortality of patients in 2 groups were recorded. Venous blood was drawn from patients of 2 groups on the morning of post treatment day (PTD) 1, 3, 5, and 7. Values of TNF-α, C-reactive protein (CRP), IL-2, and IL-10 in plasma were assayed. Results High fever appeared in 9 patients in IT group, and WBC exceeded 10.0×109 for more than 3 days in 17 patients in this group, versus 20 and 29 patients respectively in RT group. Dysfunction of 1 organ appeared in 31 pa-tients in IT group and 30 patients in RT group. Dysfunction of 3 organs appeared in 10 patients in IT group and 19 patients in RT group. Dysfunction of 4 organs appeared in 7 patients in IT group and 12 patients in RT group. In IT group, 4 patients died within 3 post-injury day (PID), and 1 patient died after PID 3 (total case fatality: 12.5% ). In RT group, 5 patients died within 3 PID, and 4 patient died after PID 3 (total case fatality: 22.5%). Plasma levels of TNF-α and CRP of patients in IT group were significantly lower than those of patients in RT group on PID 3 - 7 ( P<0.05 or P<0.01 ), while levels of IL-2 and IL-10 of patients in IT group were significantly higher than those of patients in RT group ( P<0.05 or P<0.01 ). Plasma levels of TNF-α ( 1.3±0.6 μg/L) and CRP (55±16 mg/L) of patients in IT group on PTD 7 were lowered to the trough level, and they were significantly lower than those of patients in RT group (3.0±0.8μg/L, 89±20 mg/L, respectively, P <0.01 ). Conclusions Intensive insulin therapy can mitigate systemic inflammatory response and improve prognosis of patients with severe trauma.     

强化胰岛素治疗的2型糖尿病患者胰岛素脱离与否相关因素分析

目的比较强化胰岛素治疗的2型糖尿病患者在脱离胰岛素治疗和继续胰岛素治疗时的临床特点,分析脱离胰岛素的相关因素。方法统计66例入院的2型糖尿病患者的患病时间,检测开始胰岛素强化治疗、治疗过程、治疗结束时的糖化血红蛋白(HbA1 c)、体重指数(BM I)、胰岛素用量,观察脱离胰岛素所需时间。结果34例患者脱离胰岛素治疗,32例继续治疗,两组患者在年龄、治疗开始时间、BM I、HbA1 c差异均无统计学意义,而患病时间比较差异有统计学意义(P<0.05),脱离时的胰岛素用量和HbA1 c比继续治疗患者显著减低(P<0.01)。结论患病时间长短是胰岛素脱离与否的重要因素,胰岛素投入量及HbA1 c数值对脱离胰岛素与否有积极作用。     

糖尿病肾病的防治策略和临床药物治疗

糖尿病 (DM)是遗传和环境因素共同作用下 ,胰岛素的绝对或相对缺乏或胰岛素抵抗引致的以高血糖为特征的一组代谢异常综合征。糖尿病肾病 (DN)作为DM的主要并发症 ,所占比例已达 15 %。DN不仅是西方国家导致终末期肾病(ESRD)的主要原因 ,预测也将成为发展中国家ES RD的最主要病因。因此 ,有效防治DN的发生和发展已成为一项重要任务。1　防治策略———三级预防近来人们最为熟知的DN防治策略就是三级预防。一级预防 (primaryprevention) ,患者一经诊断为DM或发现糖耐量减低 (impairedglucosetolerance ,IGT)就应积极治疗 ,已诊断为…     

高血压病的几种相关因素

高血压病是我国最常见的心血管疾病，其发病机制非常复杂。近年来，大量的试验研究发现，某些血管活性物质、高胰岛素血症、脂酯代谢异常以及不良习惯、心理因素等，在高血压病的发生发展过程中起着促进与协同作用。

代谢综合征患者胰岛素敏感性和β细胞功能研究

目的研究单纯性肥胖、单纯性高血压、肥胖伴糖耐量减退(IGT)、高血压伴IGT和肥胖2型糖尿病(T2DM)患者的胰岛素敏感性及早期胰岛β细胞功能. 方法用减少样本数的Bergman最小模型技术结合多样本静脉葡萄糖耐量(FSIGT)试验分别测定各类受试组患者的胰岛素敏感性指数(SI)、葡萄糖自身代谢效能(SG),并计算FSIGT试验中推注葡萄糖后胰岛素分泌第一时相时的胰岛素峰值与基础值之差(Ip-b),进而评估各组人群早期胰岛β细胞的胰岛素分泌功能. 结果1.正常组、单纯性肥胖组及单纯性高血压组间的SG无显著性差异,但均明显高于肥胖伴IGT、高血压伴IGT和T2DM组,后三组间的SG无显著差异.2.正常组的SI显著高于其他病理性5组.3.与正常组相比,单纯性肥胖组、高血压伴IGT组Ip-b值明显升高,肥胖伴IGT和T2DM组Ip-b值明显降低. 结论胰岛早期β细胞分泌功能在单纯性高血压组正常,在单纯性肥胖、高血压伴IGT组处于代偿性亢进状态,而在肥胖的T2DM及肥胖伴IGT患者,机体早期即刻葡萄糖负荷后胰岛β细胞分泌胰岛素功能已经不足,以前者更为严重,甚至缺如.     

高果糖诱导IR大鼠模型血清脂质代谢的改变及意义

目的: 评估高果糖膳食对机体胰岛素敏感性及血清脂质代谢的影响及意义.方法:以高果糖膳食(果糖占总热量34.5%)诱导并经钳夹技术证实建立胰岛素抵抗(IR)大鼠模型,生化比色法测定血清游离脂肪酸(FFA),生化酶法测定血清甘油三酯(TG)及总胆固醇(TC).结果:高果糖膳食喂养4周后,实验组大鼠葡萄糖输注率由(11.5±0.6)mg/kg·min-1下降至(6.6±0.4)mg/kg·min-1(P<0.01);血清FFA由(0.45±0.09)mmol/L增至(0.78±0.19)mmol/L(P<0.01);TG由(0.54±0.10)mmol/L增至(0.96±0.22)mmol/L(P<0.01);TC由(1.96±0.32)mmol/L增至(2.42±0.21)mmol/L(P<0.01).结论:高果糖膳食可导致机体严重IR,是建立IR大鼠模型的有效手段;该模型同时伴有血清脂代谢各相关指标的明显异常,血脂的变化既是IR的结果,也是IR向纵深发展的原因和必要条件.
