Fentanyl and the interleukin-6 response to surgery   总被引:12,自引:0,他引:12  
It has been suggested that large doses of opioids may suppress the interleukin-6 response to surgery. We examined the effects of the supplementation of inhalational anaesthesia with either 3 or 15 μg.kg−1 fentanyl on the circulating interleukin-6, interleukin-8, C-reactive protein, cortisol and glucose concentrations in 16 patients undergoing pelvic surgery. In both groups, surgery evoked the expected glucose, cortisol and interleukin-6 response but no increase in interleukin-8 was detected. There were no significant differences between the two groups. We conclude that the supplementation of inhalational anaesthesia with conventional doses of opioids does not modify the cytokine response to surgery.  相似文献

Summary Levels of soluble IL-2 receptors, IL-6, soluble CD23, soluble CD14 and ECP (eosinophilic cationic protein) were measured as markers of T-cell, B-cell, monocyte and eosinophilic leucocyte activation in 26 patients with atopic dermatitis (AD) on admission to (A) and at discharge from (D) the Department of Dermatology in Zurich. The serum levels of sIL-2R, IL-6, sCD23, sCD14 and ECP were significantly elevated in AD patients in comparison with the normal values of healthy donors. A significant decrease in sIL-2R (p=0.0093) and in sCD14 (p=0.0134) levels was demonstrated between A and D, correlating with the improvement in the skin intensity score (SIS). In addition, a significant correlation of the sCD14 levels and the SIS at A was demonstrated (p=0.0415). These results also incriminate monocytes in the pathogenesis of AD, indicating that, besides sIL-2R and ECP, SCD14 could also be a possible marker for the disease activity.  相似文献

硬膜外腔阻滞对胸部手术应激反应的影响   总被引:33,自引:1,他引:32  
目的 观察硬膜外腔阻滞对胸部手术应激激素和细胞因子的影响。方法20例食管癌手术病人,随机分为两组,每组10例,即全麻复令硬膜外腔阻滞(GEA)组和全麻(GA)组,分别测定麻醉诱导前、手术2h、手术4h、术毕、术后1d及术后3d的血浆去甲肾上腺素、肾上腺素、血清促肾上腺皮质激素(ACTH)、皮质醇、C-反应蛋白、IL-6及IL-10的水平。结果 血浆去甲肾上腺素和血清皮质醇GEA组术中术后无显著改变,但GA组术毕和术后1d显著升高(P<0.05),术后3d恢复至术前水平,组间比较前者有显著差异(P<0.05)。两组血浆肾上腺素、IL-10术中术后均无显著变化。两组血清ACTH、IL-6及CRP术中术后均显著升高(P<0.05),组间比较无显著差异。结论 硬膜外腔阻滞可以减轻胸部手术的应激反应。IL-6是较CRP更灵敏的反映组织损伤的炎性指标。  相似文献

Interleukin–2 and hyperthermia have been used individually to treat a variety of tumors in both experimental and human trials. Combined adoptive immunotherapy and hyperthermia is an exciting new line of investigation. Previous work in our laboratory has shown that combined local hyperthermia and rIL-2 therapy can significantly decrease the rate of tumor growth. In this study, we investigated the effect of combined whole-body hyperthermia (WBHT) and rIL-2 on the growth of subcutaneous MCA-105 murine tumors in C57BL/6 mice. Treatment of both microscopic (day 3) and macroscopic (day 10) tumors was evaluated. In the treatment of microscopic tumors, animals received either no treatment; rIL-2 (3 × 105 IU ip tid) on days 3–7; plus WBHT(41°C for 30 min) on days 3, 5, and 7; or WBHT only on days 3, 5, and 7. In treating macroscopic tumors, animals received either no treatment; rIL-2 on days 10–14; plus WBHT on days 10, 12, and 14; or WBHT only on days 10, 12, and 14. While combined treatment and WBHT alone had no significant effect on the growth of microscopic tumors, combined IL-2 and WBHT significantly reduced the rate of tumor growth of macroscopic tumors. These results suggest that the tumor microenvironment plays a critical role in combined WBHT and rIL-2 therapy, and may be due to effects of WBHT on the tumor vasculature. © 1993 Wiley-Liss, Inc.  相似文献

BACKGROUND: In chronic ambulatory peritoneal dialysis, bicarbonate-buffered fluids, with their neutral pH and less advanced glycosylation end-products (AGE) and glucose degradation products (GDP), have better biocompatibility than conventional peritoneal dialysis (PD) solutions. That difference may be more beneficial in automated peritoneal dialysis (APD), due to its more frequent exchanges and longer contact times with fresh dialysate. We performed a prospective, randomized study in APD patients to compare the biocompatibility of conventional and bicarbonate/lactate-buffered PD fluids. METHODS: We randomized 14 APD patients to have APD with either conventional or bicarbonate/lactate-based fluids. After 6 months, both groups changed to the other solution. The overall observation period was 12 months. After 1 and 5 months and again after 7 and 11 months, phagocytotic and respiratory burst capacities of effluent peritoneal macrophages were determined. Plasma interleukin (IL)-6 and C-reactive protein (CRP) as well as effluent IL-6, CRP, transforming growth factor (TGF)-beta 1, AGE and CA125 concentrations were measured. Inflow pain was quantified using a patient questionnaire. RESULTS: Respiratory burst capacity remained unchanged and phagocytotic activity increased significantly during APD (P<0.001) with the bicarbonate/lactate fluid. Effluent IL-6 release was significantly lower than with the lactate fluid (P<0.05). While in the effluent TGF-beta 1 was unaffected, AGE concentration was lower after bicarbonate/lactate treatment (P<0.05). Effluent CA125 concentration, an indicator of mesothelial cell integrity, was higher (P<0.05) in neutral effluents. Finally, patients' inflow pain diminished (P = 0.05) when using the neutral fluid. CONCLUSIONS: The use of a neutral PD fluid in APD improved patients' inflow pain as well as biocompatibility parameters reflecting enhanced phagocytotic activity of peritoneal macrophages, reduced constitutive inflammatory stimulation (IL-6), reduced AGE accumulation in the peritoneal cavity and better preservation of the mesothelial cell integrity. From the biocompatibility point of view, a neutral fluid with low GDP content can be recommended as the primary choice for APD.  相似文献

目的观察正常人的低密度脂蛋白(native low density lipoprotein,nLDL),人工氧化的低密度脂蛋白(oxidized lowdensity lipoprotein,ox-LDL)及非胰岛素依赖型糖尿病(Non-insulin dependent diabetes mellitus,MDDM)患者的低密度脂蛋白(diabetic low density lipoprotein,dLDL)对兔胸主动脉环内皮的损伤作用及左旋精氨酸(L-arginine,L-Arg),维生素B6(pyridoxine,VB6)的拮抗效应.方法采用离体动脉环灌流的方法,观察兔胸主动脉环对乙酰胆碱(acetycholine,Ach),钙离子载体A23187的舒张反应.结果3种LDL均抑制动脉环对Ach及A23187的舒张,损伤强度为ox-LDL>dLDL>nLDL,并具有浓度依赖性;L-Arg、VB6能明显拮抗LDL的抑制作用,但并不能完全逆转.以SOD作为保护药对照,250 U/ml的浓度能够显著抑制dLDL对内皮的损伤.结论3种低密度脂蛋白主要可能通过降低NO生物活性损伤内皮,L-Arg、VB6具有内皮保护作用.  相似文献

The Van der Woude syndrome: a case report and review of the literature   总被引:1,自引:0,他引:1  
The Van der Woude syndrome is a rare autosomal dominant developmental malformation usually associated with bilateral lower lip pits. These congenital lip pits appear clinically as a malformation in the vermilion border of the lip, with or without excretion. As a genetic defect has been identified as a microdeletion of chromosome bands 1q32-q41, genetic counselling of patients may be considered. A nonsense mutation in the interferon regulatory factor-6 (IRF-6) is discussed as a pathogenic relevant factor. Therapeutic intervention is generally not necessary, although surgical excision is especially indicated in patients with recurrent inflammation. Physicians should be aware of the Van der Woude syndrome because it has been reported to be associated with a variety of malformations or other congenital disorders.  相似文献

Inflammatory biomarkers in blood of patients with acute brain ischemia   总被引:11,自引:0,他引:11  
Although many failed surrogate markers are provided in the literature, inflammation may contribute to the outcome of ischemic stroke. In 50 consecutive patients with acute ischemic stroke, in the absence of symptoms and signs of concomitant infection, we evaluated a panel of biomarkers reported to be variably associated with brain ischemia, and correlate their serum level with the brain lesion volume and clinical outcome. Infarct size was calculated on computed tomography (CT) scans by means of the Cavalieri's method. Neurological impairment was scored by using the Glasgow Coma Scale, Glasgow Outcome Scale and National Institutes of Health (NIH) scales at stroke onset and 3-month follow-up. Some markers showed a direct significant correlation with both initial and final NIH scale and with infarct size, particularly tumor necrosis factor alpha (TNF-alpha) (P=0.002), intercellular adhesion molecule-1 (P<0.01) and matrix metalloproteinase-2/9 (P=0.001). In contrast to previous reports, interleukin-6 (IL-6) serum level showed a significant inverse correlation with both final neurological impairment and infarct size (P<0.001). This novel finding allows us suggesting that IL-6, in the context of a complex pro-inflammatory network occurring during stroke, is associated with neuroprotection rather than neurotoxicity in patients with ischemic brain injury.  相似文献
