interleukin-8 and Constriction--Pathologic

Minimally invasive surgical techniques have been shown to reduce the inflammatory response related to a surgical procedure. The main objective of our study was to measure the inflammatory response in patients undergoing a totally laparoscopic versus open aortobifemoral bypass surgery. This is the first randomized trial on subjects in this population.. This is a substudy of a larger randomized controlled multicenter trial (Norwegian Laparoscopic Aortic Surgery Trial). Thirty consecutive patients with severe aortoiliac occlusive disease eligible for aortobifemoral bypass surgery were randomized to either a totally laparoscopic (n=14) or an open surgical procedure (n=16). The inflammatory response was measured by perioperative monitoring of serum interleukin-6 (IL-6), IL-8, and C-reactive protein (CRP) at six different time points.. The inflammatory reaction caused by the laparoscopic procedure was reduced compared with open surgery. IL-6 was significantly lower after the laparoscopic procedure, measured by comparing area under the curve (AUC), and after adjusting for the confounding effect of coronary heart disease (. In this substudy of a randomized controlled trial comparing laparoscopic and open aortobifemoral bypass surgeries, we found a decreased perioperative inflammatory response after the laparoscopic procedure measured by comparing AUC for serum IL-6.

To explore the inhibitory effect of verapamil, a calcium channel blocker, on the growth of human airway granulation fibroblasts to provide an experimental basis for the clinical use of calcium channel blockers in preventing and treating benign airway stenosis.. Primary human airway normal fibroblasts and human airway granulation fibroblasts were cultured by tissue block attachment culture method, and the experimental studies were carried out using 3-8 generation cells. Cell Counting Kit-8 (CCK-8) was used to test the proliferation of human normal airway fibroblasts and human airway granulation fibroblasts and the semi-inhibitory concentration of verapamil on normal airway fibroblasts and airway granulation fibroblasts. A scratch test detected the migration effect of verapamil on human airway granulation fibroblasts. The mRNA relative expression levels of related factors were detected by PCR to compare the differences between normal airway fibroblasts and airway granulation fibroblasts. Western blot was used to detect the relative amount of related proteins and compare the differences between normal airway fibroblasts and granulation airway fibroblasts. After 48 hours of treatment with half of the inhibitory concentration of Vera Pammy for granulation airway fibroblasts, the relative expression levels of related factors on mRNA and protein were observed.. Human normal airway fibroblasts and human airway granulation fibroblasts with a purity of more than 95% could be obtained from primary culture by tissue block adherence method. CCK8 results showed that the proliferation rate of human airway granulation fibroblasts was faster than that of the normal human airway fibroblasts. The semi-inhibitory concentration of verapamil on human normal airway fibroblasts was 92.81 ug/ml, while the semi-inhibitory concentration on human airway granulation fibroblasts was 69.57 ug/ml. The scratch test indicated that the cell migration rate of human airway granulation fibroblasts treated with verapamil decreased significantly (P < 0.05). PCR results showed that the mRNA relative expression levels of TGFβ1, COL1A1, Smad2/3, VEGFA, IL6, and IL8 in human airway granulation fibroblasts were significantly higher than those in normal human airway fibroblasts (P < 0.05). The mRNA relative expressions of TGFβ1, smad2/3, and COL1A1 in human airway granulation fibroblasts treated with semi-inhibited verapamil for 48h were down-regulated (P < 0.05), while the mRNA relative expressions of VEGFA, IL6 and IL8 had no significant changes (P > 0.05). WB test showed that the relative protein expressions of TGFβ1, Smad2, and VEGFC in human airway granulation fibroblasts were upregulated (P < 0.05) but downregulated after verapamil treatment compared with before treatment (P < 0.05).. Calcium channel blockers can inhibit the proliferation of human airway granulation fibroblasts through TGFβ1/ Smad pathway, which may be a method to prevent and treat benign airway stenosis.

Brain-derived neurotrophic factor (BDNF) regulates the lipid metabolism, atherosclerosis plaque formation, and inflammatory process, while the study about its clinical role in coronary heart disease (CHD) is few. The present study intended to explore the expression of BDNF and its relationship with stenosis, inflammation, and adhesion molecules in CHD patients.. After serum samples were obtained from 207 CHD patients, BDNF, tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β, IL-6, IL-8, IL-17A, vascular cell adhesion molecule-1 (VCAM-1), and intercellular adhesion molecule-1 (ICAM-1) levels were determined using ELISA. Then, the BDNF level was also examined in 40 disease controls (DCs) and 40 healthy controls (HCs), separately.. BDNF was lower in CHD patients than in DCs and HCs (median (95% confidential interval) value: 5.6 (3.5-9.6) ng/mL vs. 10.7 (6.1-17.0) ng/mL and 12.6 (9.4-18.2) ng/mL, both p < 0.001). BDNF could well distinguish CHD patients from DCs (area under the curve [AUC]: 0.739) and HCs (AUC: 0.857). BDNF was negatively associated with triglyceride (p = 0.014), total cholesterol (p = 0.037), and low-density lipoprotein cholesterol (p = 0.008). BDNF was negatively associated with CRP (p < 0.001), TNF-α (p < 0.001), IL-1β (p = 0.008), and IL-8 (p < 0.001). BDNF was negatively related to VCAM-1 (p < 0.001) and ICAM-1 (p = 0.003). BDNF was negatively linked with the Gensini score (p < 0.001).. BDNF reflects the lipid dysregulation, inflammatory status, and stenosis degree in CHD patients.

What is this article about? This study aimed to find the clinical value of measuring the protein ITIH4 in patients with coronary heart disease (CHD). What was done? A total of 300 CHD patients and 30 non-CHD people (with chest pain or suspected CHD symptoms) were enrolled in this study. Blood ITIH4 levels of all people were detected. What were the results? Blood ITIH4 levels were lower in CHD patients compared with non-CHD people. In CHD patients, a high level of ITIH4 was associated with low inflammation, reduced vessel narrowness and a good prognosis. What do the results mean? Blood ITIH4 serves as an anti-inflammatory biomarker, whose high level represents better conditions in CHD patients.

We hypothesized that repetitive umbilical cord occlusions (UCOs) with worsening acidosis will lead to a fetal inflammatory response.. Chronically instrumented fetal sheep underwent a series of UCOs until fetal arterial pH decreased to <7.00. Maternal and fetal blood samples were taken for blood gases/pH and plasma interleukin (IL)-1B and IL-6 levels. Animals were euthanized at 24 hours of recovery with brain tissue processed for subsequent measurement of microglia and mast cell counts.. Repetitive UCOs resulted in a severe degree of fetal acidemia. Fetal plasma IL-1B values were increased approximately 2-fold when measured at maximal fetal acidosis and again at 1-2 hours of recovery. Fetal microglia cells were increased approximately 2-fold in the white matter and hippocampus, while mast cells were increased approximately 2-fold in the choroid plexus and now evident in the thalamus when analyzed at 24 hours recovery.. Repetitive UCOs leading to severe acidemia in the ovine fetus near term will result in an inflammatory response both systemically and locally within the brain.

The vaso-occlusive process (VOC) in sickle cell disease is of a complex nature. It involves intricate interactions between sickle red blood cells, endothelium and probably also leukocytes. As these interactions are regulated by cytokines, we analyzed the role of the potent neutrophil chemokine IL-8 by measuring serum levels in sickle cell patients during sickle cell crisis. These results were compared to nonsymptomatics and healthy controls. In patients having a vaso-occlusive crisis both HbSS and HbSC patients showed significantly enhanced serum IL-8 levels compared to healthy controls. Several of these patients showed extremely elevated serum IL-8 levels which were independent of the crisis inducing factor. Furthermore, a sickle cell patient with VOC as a complication of rhGM-CSF treatment similarly showed high IL-8 serum levels at crisis onset. Nonsymptomatic sickle cell patients serum IL-8 levels were comparable to healthy controls. These results implicate a role for IL-8 at or during (the initiation of) sickle cell crisis.
