Adipose tissue synthesizes and secretes a wide range of biologically active molecules considered as inflammatory markers whose dysregulation in obesity plays a role in the development of insulin resistance and vascular disorders. Thus, finding genes that influence circulating levels of inflammatory biomarkers may provide insights into the genetic determinants of obesity-related metabolic diseases. We performed linkage analyses for fasting plasma levels of adiponectin, C-reactive protein (CRP), interleukin-6 (IL-6) and tumor-necrosis factor-alpha (TNF-alpha) in 764 subjects enrolled in the Quebec family study (QFS). A maximum of 393 pairs of siblings from 211 nuclear families were available for analyses. A total of 443 markers spanning the 22 autosomal chromosomes with an average inter-marker distance of 6.24 Mb were genotyped. Linkage was tested using both allele-sharing (SIBPAL) and variance component linkage methods (MERLIN). We showed suggestive evidence of linkage for plasma adiponectin levels on chromosome 15q21.1 [D15S659; logarithm of the odds (LOD) score = 2.23], 3q13.33 (D3S3023; LOD = 2.09), 20q13.2 (D20S197; LOD = 1.96) and 14q32.2 (D14S1426; LOD = 1.79). Evidence of linkage (SIBPAL) was also found for CRP on 12p11.23 (P = 0.001) and 12q15 (P = 0.0005) and for IL-6 on 14q12 (P = 0.002). None of these linkages remained significant after adjustment for body mass index. No evidence of linkage was found for TNF-alpha plasma levels. These results suggest that several QTLs can influence plasma levels of adiponectin and CRP, partly via their effects on adiposity. 相似文献

Hypoxemia increases serum interleukin-6 in humans 总被引:4,自引:0,他引:4

Serum concentrations of interleukin (IL) 1 beta, IL-1 receptor antagonist (IL-1ra), IL-6, tumor necrosis factor (TNF) alpha,
and C-reactive protein (CRP) were determined in ten healthy men at sea level and during four days of altitude hypoxia (4350m
above sea level). The mean (SD) arterial blood oxygen saturations were 78.6 (7.3)%, 82.4 (4.9)%, and 83.4 (5.3)% in the first,
second, and third days at altitude, respectively. A symptom score of acute mountain sickness (AMS) revealed that the subjects
had mostly light symptoms of AMS. Mean serum IL-6 increased from 1.36 (1.04) pg × ml–1 at sea level to 3.10 (1.65), 4.71 (2.81), and 3,54 (2.17) pg × ml–1 during the first three days at altitude, and to 9.96 (8.90) pg × ml–1 on the fourth day at altitude (ANOVA p =0.002). No changes occurred in serum concentrations of IL-1 beta, IL-1ra, TNF alpha, or CRP. The serum IL-6 were related
to SaO2, ( r =–0.45, p =0.003), but not to heart rates or AMS scores. In conclusion, human serum concentrations of IL-6 increased during altitude
hypoxia whereas the other proinflammatory cytokines remained unchanged. The major role of IL-6 during altitude hypoxia seem
not to be mediation of inflammation, instead, the role of IL-6 could be to stimulate the erythropoiesis at altitude.

Objective: The purpose of this study was to investigate whether routine blood tests on admission and clinical characteristics can predict prognosis in patients with traumatic brain injury (TBI) combined with extracranial trauma.Methods: Clinical data of 182 patients with TBI combined with extracranial trauma from April 2018 to December 2019 were retrospectively collected and analyzed. Based on GOSE score one month after discharge, the patients were divided into a favorable group (GOSE 1-4) and unfavorable group (GOSE 5-8). Routine blood tests on admission and clinical characteristics were recorded.Results: Overall, there were 48 (26.4%) patients with unfavorable outcome and 134 (73.6%) patients with favorable outcome. Based on multivariate analysis, independent risk factors associated with unfavorable outcome were age (odds ratio [OR], 1.070; 95% confidence interval [CI], 1.018-1.124; p<0.01), admission Glasgow Coma Scale (GCS) score (OR, 0.807; 95% CI, 0.675-0.965; p<0.05), heart rate (OR, 1.035; 95% CI, 1.004-1.067; p<0.05), platelets count (OR, 0.982; 95% CI, 0.967-0.997; p<0.05), and tracheotomy (OR, 15.201; 95% CI, 4.121-56.078; p<0.001). Areas under the curve (AUC) of age, admission GCS, heart rate, tracheotomy, and platelets count were 0.678 (95% CI, 0.584-0.771), 0.799 (95% CI, 0.723-0.875), 0.652 (95% CI, 0.553-0.751), 0.776 (95% CI, 0.692-0.859), and 0.688 (95% CI, 0.606-0.770), respectively.Conclusions: Age, admission GCS score, heart rate, tracheotomy, and platelets count can be recognized as independent predictors of clinical prognosis in patients with severe TBI combined with extracranial trauma. 相似文献

C-reactive protein (CRP) response is abnormal to a non-infectious inflammation in systemic lupus erythematosus (SLE). We evaluated the role of cytokines in this CRP unresponsiveness. The sera of 138 SLE patients and 71 rheumatoid arthritis patients were collected prospectively. SLE with infection had higher WBC count, ESR, CRP and C4 levels than those without infection. IL-6, IL-10 and IFN-gamma levels were higher in SLE with infection than SLE without infection. In SLE with infection, the CRP was correlated with the IL-6 (r = 0.77, P < 0.001) but not correlated with IL-10 and IFN-gamma. These data suggest that IL-6 may have a role in the unresponsiveness of CRP to a non-infectious inflammation of SLE. 相似文献

目的探讨妊娠妇女血清c反应蛋白(CRP)预测妊娠糖尿病(GDM)的价值。方法对484名早孕妇女进行前瞻性研究,用免疫散射比浊法检测早孕妇女血清CRP并追踪至孕中晚期,根据孕中晚期75g糖耐量结果分为GDM组、IGT组,选取年龄、孕周相同的作为正常对照组,对3组间孕早期、孕中晚期的CRP进行分析。结果GDM的发生率为4.5%、IGT的发生率为5.12%。孕早期3组间血清CRP水平差异无统计学意义;孕中晚期GDM组、IGT组血清CRP浓度明显高于正常对照组,差异有显著性;孕前BMI与CRP存在正相关性。当校正孕前BMI进行协方差分析后,GDM组、IGT组血清CRP与正常组血清CRP差异有统计学意义,GDM组、IGT组差异无显著意义。结论妊娠早期血清CRP水平不能预测GDM的发生,孕中晚期血清CRP水平高低对GDM有诊断价值。 相似文献
