Increased expression of TNF-alpha,IL-6, and IL-8 in HALS: implications for reduced adiponectin expression and plasma levels

Human immunodeficiency virus (HIV)-associated lipodystrophy syndrome (HALS) is a side effect of highly active antiretroviral therapy of HIV-infected patients; however, the mechanism of the lipodystrophy and insulin resistance seen in this syndrome remains elusive. Adiponectin, an adipocyte-specific protein, is thought to play an important role in regulating insulin sensitivity. We investigated circulating levels and gene expression of adiponectin in subcutaneous abdominal adipose tissue (AT) from 18 HIV-infected patients with HALS compared with 18 HIV-infected patients without HALS. Implications of cytokines for adiponectin levels were investigated by determining circulating levels of TNF-alpha, IL-6, and IL-8 as well as gene expression of these cytokines in AT. HALS patients exhibited 40% reduced plasma adiponectin levels (P < 0.05) compared with non-HALS subjects. Correspondingly, adiponectin mRNA levels in AT were reduced by >50% (P = 0.06). HALS patients were insulin resistant, and a positive correlation was found between plasma adiponectin and insulin sensitivity (r = 0.55, P < 0.01) and percent limb fat (r = 0.61, P < 0.01). AT mRNA of TNF-alpha, IL-6, and IL-8 was increased in AT of HALS subjects (P < 0.05), and both AT TNF-alpha mRNA and plasma TNF-alpha were negatively correlated to plasma adiponectin (P < 0.05). Finally, TNF-alpha was found in vitro to inhibit human AT adiponectin mRNA by 80% (P < 0.05). In conclusion, HALS patients have reduced levels of plasma adiponectin and adiponectin mRNA in AT. Increased cytokine mRNA in AT is hypothesized to exert an inhibitory effect on adiponectin gene expression and, consequently, to play a role in the reduced plasma adiponectin levels found in HALS patients.     

血清PCT、IL-17与CRP在AECOPD合并肺动脉高压患者中的表达及诊断价值

目的:探讨降钙素原(PCT),白介素17(IL-17)与C反应蛋白(CRP)在慢性阻塞性肺疾病急性加重期(AECOPD)合并肺动脉高压患者外周血中的表达水平,探究联合检测的诊断价值。方法:收集2015年8月至2017年2月我院收治的AECOPD患者120例,纳入研究患者根据是否合并肺动脉高压分为分为单纯AECOPD组60例及AECOPD合并肺动脉高压(AECOPD+PH)组60例,另选取20例健康志愿者作为对照组。采用化学发光法检测PCT水平,双抗夹心酶联免疫吸附试验法(ELISA)检测IL-17水平及生化分析仪检测CRP水平,采用受试者工作特征曲线(ROC)评估PCT,IL-17与CRP对AECOPD合并肺动脉高压的诊断价值。结果:AECOPD+PH组及AECOPD组的PCT,IL-17,CRP水平较健康对照组均明显升高,而AECOPD+PH组的各指标水平也均高于单纯AECOPD组,差异均有统计学意义(P0.05)。通过Pearson相关性分析发现,AECOPD合并肺动脉高压的PCT与IL-17之间存在表达正相关性(r=0.733,P0.05),PCT与CRP表达存在正相关性(r=0.817,P0.05)。此外,针对AECOPD合并肺动脉高压的诊断中PCT的ROC曲线下面积为0.83,IL-17为0.71,CRP为0.77,联合三者的ROC曲线下面积为0.94。结论:PCT、IL-17和CRP可能与AECOPD患者肺动脉高压的形成有关,各指标存在一定的相关性,联合以上三项生物学指标对诊断AECOPD合并肺动脉高压患者具有一定的临床参考价值。     

幽门螺旋杆菌感染与慢性胃炎患者IL-8、IL-10、CRP水平以及血脂指标的关系研究

目的:研究幽门螺旋杆菌(Hp)感染与慢性胃炎患者白细胞介素-8(IL-8)、白细胞介素-10(IL-10)、C反应蛋白(CRP)水平以及血脂指标的关系。方法:选择从2015年6月到2017年6月在我院接受治疗的慢性胃炎患者150例作为观察组,根据13C-尿素呼吸实验的结果将观察组患者分成HP阳性组71例和Hp阴性组79例,另选同期在我院进行健康体检的志愿者150例作为对照组,对比观察组以及对照组的炎症因子IL-8、IL-10、CRP及血脂指标[低密度脂蛋白(LDL-C)、高密度脂蛋白(HDL-C)、甘油三酯(TG)、总胆固醇(TC)]水平,并对比观察组不同HP感染情况的炎症因子及血脂指标水平,分析Hp感染与患者炎症因子及血脂指标水平的相关性。结果:观察组的IL-8、IL-10、CRP、LDL-C及TG水平均分别高于对照组,差异均有统计学意义(均P0.05)。Hp阳性组患者治疗前的IL-8、IL-10、CRP、LDL-C及TG水平均分别高于HP阴性组,但Hp阳性组患者治疗后的上述指标水平均分别低于HP阴性组,差异均有统计学意义(均P0.05)。两组治疗后的IL-10、CRP水平均分别低于治疗前,且Hp阳性组患者的IL-8、LDL-C及TG水平也低于治疗前,差异均有统计学意义(均P0.05),Spearman相关性分析结果显示,Hp感染与患者IL-8、IL-10、CRP、LDL-C及TG水平均呈正相关(均P0.05),但Hp感染与HDL-C和TC并无明显的相关性(P0.05)。结论:Hp感染与慢性胃炎患者的炎症指标及血脂指标关系紧密,临床上可考虑将此类指标作为存在Hp感染的慢性胃炎患者的监测指标,从而更好地辅助临床诊治。     

Postoperative changes in serum cytokines profile and nitric oxide levels in patients with cystic echinococcosis

The aim of the present study was to examine serum cytokines and nitric oxide (NO) levels in patients with cystic echinococcosis (CE). 28 patients with CE were studied and all underwent surgery. Serum levels of tumour necrosis factor-alpha (TNF-alpha), interleukin IL-1beta, receptor of soluble IL-2R (sIL-2R), IL-6, IL-8, nitrate/nitrite, and C-reactive protein (CRP) were determined before and after induction of treatment. Data were compared with those obtained from 28 healthy volunteers. IL-6 was elevated in all CE patients (100%). IL-8 was increased in 11/28 (39.3%). Increased levels of IL-2R and TNF-alpha were found in a limited number of them particularly those showing cysts in the central area of the liver (5/28, 6/28). IL-1beta level was not elevated in any patient except in secondary severe CE. CRP and nitrate/nitrite levels were also increased. A positive correlation between CRP and IL-6 (r = 0.74; p < 0.001) was found confirming the link between inflammation due to CE and activation of monocytes. All patients completely recovered and the levels of the studied parameters reverted to normal levels except one patient in whom severe recurrent disease occurred two years after the first operation. These results suggest that there are different immunoregulatory events and cytokines response during CE and may be in part related to slight monocytosis and in part to Th2 activation. IL-6, NO and CRP were unambiguously involved in the host parasite interaction and therefore may be useful markers in monitoring CE management and evaluating surgical stress.     

High altitude increases circulating interleukin-6, interleukin-1 receptor antagonist and C-reactive protein

Hypoxic pulmonary vasoconstriction is associated with but may not be sufficient for the development of high-altitude pulmonary oedema (HAPO). Hypoxia is known to induce an inflammatory response in immune cells and endothelial cells. It has been speculated that hypoxia-induced inflammatory cytokines at high altitude may contribute to the development of HAPO by causing capillary leakage in the lung. We were interested if such an inflammatory response, possibly involved in a later development of HAPO, is detectable at high altitude in individuals without HAPO. We examined the plasma levels of interleukin 6 (IL-6), interleukin 1 receptor antagonist (IL-1ra) and C-reactive protein (CRP) in two independent studies: study A, Jungfraujoch, Switzerland, three overnight stays at 3458 m, n=12; study B: Capanna Regina Margherita, Italy, 3 overnight stays at 3647 m and one overnight stay at 4559 m, n=10. In both studies, probands showed symptoms of acute mountain sickness but no signs of HAPO. At the Jungfraujoch, IL-6 increased from 0.1+/-0.03 pg/ml to 2. 0+/-0.5 pg/ml (day 2, P=0.03), IL-1ra from 101+/-21 to 284+/-73 pg/ml (day 2, P=0.01), and CRP from 1.0+/-0.4 to 5.8+/-1.5 micrograms/ml (day 4, P=0.01). At the Capanna Margherita, IL-6 increased from 0. 5+/-0.2 pg/ml to 2.0+/-0.8 pg/ml (P=0.02), IL-1ra from 118+/-25 to 213+/-28 pg/ml (P=0.02), and CRP from 0.4+/-0.03 to 3.5+/-1.1 micrograms/ml (P=0.03). IL-8 was below the detection limit of the ELISA (<25 pg/ml) in both studies. The increase of IL-6 and IL-1ra in response to high altitude was delayed and preceded the increase of CRP. We conclude that: (1) circulating IL-6, IL-1ra and CRP are upregulated in response to hypobaric hypoxic conditions at high altitude, and (2) the moderate systemic increase of these inflammatory markers may reflect considerable local inflammation. The existence and the kinetics of high altitude-induced cytokines found in this study support the hypothesis that inflammation is involved in the development of HAPO.     

Effect of chromium niacinate and chromium picolinate supplementation on lipid peroxidation, TNF-alpha, IL-6, CRP, glycated hemoglobin, triglycerides, and cholesterol levels in blood of streptozotocin-treated diabetic rats

Chromium (Cr(3+)) supplementation facilitates normal protein, fat, and carbohydrate metabolism, and is widely used by the public in many countries. This study examined the effect of chromium niacinate (Cr-N) or chromium picolinate (Cr-P) supplementation on lipid peroxidation (LP), TNF-alpha, IL-6, C-reactive protein (CRP), glycosylated hemoglobin (HbA(1)), cholesterol, and triglycerides (TG) in diabetic rats. Diabetes (D) was induced in Sprague-Dawley rats by streptozotocin (STZ) (ip, 65 mg/kg BW). Control buffer, Cr-N, or Cr-P (400 microg Cr/kg BW) was administered by gavages daily for 7 weeks. Blood was collected by heart puncture using light anesthesia. Diabetes caused a significant increase in blood levels of TNF-alpha, IL-6, glucose, HbA(1), cholesterol, TG, and LP. Compared with D, Cr-N supplementation lowered the blood levels of TNF-alpha (P=0.04), IL-6 (P=0.02), CRP (P=0.02), LP (P=0.01), HbA(1) (P=0.02), TG (P=0.04), and cholesterol (P=0.04). Compared with D, Cr-P supplementation showed a decrease in TNF-alpha (P=0.02), IL-6 (P=0.02), and LP (P=0.01). Chromium niacinate lowers blood levels of proinflammatory cytokines (TNF-alpha, IL-6, CRP), oxidative stress, and lipids levels in diabetic rats, and appears to be a more effective form of Cr(3+) supplementation. This study suggests that Cr(3+) supplementation can lower the risk of vascular inflammation in diabetes.     

缺血性脑血管病患者血清MMP-8和IL-6水平与颈动脉粥样硬化的关系

Production of interleukin (IL)-1beta, IL-1 receptor antagonist and IL-10 by blood mononuclear cells in chronic arthritis

Joint erosion is a prevalent feature of rheumatoid arthritis (RA) but not of many other chronic inflammatory arthritides (non-RA). Joint destruction is mediated by cytokines, primarily interleukin (IL)-1 and tumour necrosis factor. Less erosive activity in patients with non-RA compared to RA might be related to factors that inhibit production and/or function of IL-1. Release of IL-1beta, and the two antagonists, IL-1 receptor antagonist (IL-1ra) and IL-10 from blood mononuclear cells were therefore quantitated by ELISA in 22 patients with RA, 11 with non-RA and 15 healthy age-matched controls. Release of IL-1beta was comparable between the three groups but only detectable in cultures stimulated with lipopolysaccharide; it decreased in patients treated with prednisolone: 3.8 ng/10(6)monocytes (median) vs 11.7 (P=0.045). Release of IL-1ra was in all but IgG-stimulated cultures comparable between groups. The ratio of IL-1ra/IL-1beta was elevated in LPS-stimulated cells from RA patients only: 2.0 versus 1.3 (P=0.02). In contrast, IgG-induced IL-1ra release was significantly elevated only in non-RA patients: 95 ng/10(6)monocytes vs 40 (P=0.014), and the levels correlated positively to those of blood CRP (P=0.02). Though stimulated release of IL-10 was similar between the three groups, the levels were lower in non-erosive than erosive arthritis patients, and controls (P=0. 05). In conclusion, increased IgG-stimulated IL-1ra release and elevated IL-1ra/IL-1beta ratio may protect against actions of IL-1 in vivo, and decreased release of IL-10 might be related to features of non-erosive arthritis.     

溃疡性结肠炎患者外周血C 反应性蛋白、血清降钙素原及白细胞介素-6 水平及临床意义

目的:分析溃疡性结肠炎(Ulcerative colitis,UC)患者血清降钙素原(Procalcitonin,PCT)、C反应蛋白(C-reactive protein,CRP)及白细胞介素-6(Interleukin-6,IL-6)水平与病情严重程度的关系。方法:选择2013年5月-2015年5月在我院就诊的溃疡性结肠炎患者91例作为研究对象,另选择同期在我院接受健康体检的志愿者69例作为对照组。检测并比较两组研究对象血清降钙素原(PCT)、C反应性蛋白(CRP)及白细胞介素-6(IL-6)的水平,并分析PCT,CRP及IL-6水平与溃疡性结肠炎的相关性。结果:溃疡性结肠炎患者PCT水平为(1.24±0.23)ng/m L,对照组PCT水平为(0.12±0.10)ng/m L,溃疡性结肠炎患者PCT水平显著高于对照组,差异具有统计学意义(P0.05);溃疡性结肠炎患者CRP水平为(105.27±19.93)mg/m L,对照组CRP水平为(7.62±2.97)mg/m L,溃疡性结肠炎患者血清CRP水平显著高于对照组,差异具有统计学意义(P0.05);溃疡性结肠炎患者IL-6水平为(248.15±35.60)ng/m L,对照组IL-6水平为(144.05±20.26)ng/m L,溃疡性结肠炎患者血清IL-6水平显著高于对照组,差异具有统计学意义(P0.05)。溃疡性结肠炎患者血清PCT,IL-6及CRP水平之间均呈正相关关系(r=0.301,0.468,0.413,P0.01)。结论:溃疡性结肠炎患者血清PCT,CRP及IL-6水平均显著高于健康人群,其水平变化与患者病情严重程度有关。因此,我们在临床实践中应予以重视。     

NF-κ B激活在兔急性心肌梗死再灌注后无复流中的意义

目的：观察心肌核因子-κB（NF-κB）在急性心肌梗死（AMI）再灌注后无复流的活化情况,探讨NF-κB促进无复流发生发展的作用机制。方法：24只新西兰大白兔随机分为假手术组（冠状动脉只穿线不结扎）和缺血再灌注组（结扎冠状动脉2小时,再灌注1小时）,每组12只。采用凝胶阻滞迁移分析方法（EMSA）检测正常区、缺血区和无复流区心肌组织中NF-κB活性;ELISA法测定不同时点血浆中白细胞介素-6（IL-6）、超敏C反应蛋白（CRP）以及肿瘤坏死因子-α（TNF-α）的含量;光镜、电镜观察心肌组织病理变化。结果：（1）与正常区相比,缺血区和无复流区心肌组织中NF-κB活性异常升高（P〈0.01）。（2）与结扎前相比结扎后2h、再灌注后1h血浆IL-6、CRP、TNF-α水平呈进行性升高（P均〈0.05）。（3）NF-κB的活性与无复流面积、血浆IL-6、CRP以及TNF-α水平呈正相关（分别为r=0.844,P〈0.01;r=0.682,P〈0.05;r=0.687,P〈0.05;r=0.893,P〈0.01）。（4）无复流面积与血浆IL-6、CRP以及TNF-α水平呈正相关（分别为r=0.861,P〈0.01;r=0.806,P〈0.01;r=0.877,P〈0.01）。（5）光镜及电镜结果显示无复流区的心肌组织损伤较缺血区更为严重。结论：急性心肌梗死再灌注后无复流现象的发生可能与局部心肌组织中NF-κB的过度活化有关,活化的NF-κB通过促进IL-6、TNF-α等炎症因子的表达,参与无复流的发生发展过程。     

Influence of the IL-6 -572C>G polymorphism on inflammatory markers according to cigarette smoking in Korean healthy men

We investigated whether smoking would interact with the interleukin-6 (IL-6) polymorphisms (-174G>C and -572C>G, -597G>A and -1363G>T) in determining circulating levels of inflammatory markers and its consequence to oxidative stress. The G/G genotype (n=26) of the -572C>G in nonsmokers (n=376) was associated with higher IL-6 (P=0.028), fibrinogen (P=0.007) and ox-LDL (P=0.006) than those with C/C (n=209) or C/G (n=141). Results were similar for nonsmokers and smokers (n=268), but in smokers, the -572G/G genotype was associated with a greater difference in levels of IL-6 (P=0.031), fibrinogen (P=0.001), ox-LDL (P=0.037) and PGF(2alpha) (P=0.050). IL-6 had positive relations with CRP, fibrinogen, ox-LDL and PGF(2alpha). There was no evidence of an effect of -572C>G genotype on CRP levels in nonsmokers, however, this polymorphism was associated with a highly significant effect on CRP in smokers (P<0.001) (genotype-smoking interaction P=0.04, adjusted for age, BMI and IL-6). The C allele frequency at the -174 promoter region of IL-6 was very rare (<0.01) and -597G>A and -1363G>T were monomorphic in this study. Our results suggest that IL-6 -572C>G has a greater response over time to the inflammatory effects of smoking and this may result in smokers having higher oxidative stress in subjects with G/G compared to C/C or C/G.     

Relationship between circulating interleukin-10 (IL-10) with interleukin-6 (IL-6) type cytokines (IL-6, interleukin-11 (IL-11), oncostatin M (OSM)) and soluble interleukin-6 (IL-6) receptor (sIL-6R) in patients with multiple myeloma

We investigated the serum concentration of the interleukin-10 (IL-10), along with cytokines of interleukin-6 (IL-6) family (IL-6, IL-11 and oncostatin M - OSM), as well as soluble receptor for IL-6 (sIL-6R), in 121 patients with multiple myeloma (MM) and 28 healthy subjects. We studied the interactions between IL-10 and other cytokines, and the receptor. The correlation between IL-10 and some clinical and laboratory parameters associated with the disease activity were also analysed. The IL-10 was detectable in all patients with multiple myeloma and in all controls. The IL-10 concentration was significantly increased in myeloma patients compared with healthy persons (mean - 7.09 and 2.1 pg/ml, respectively) (p = 0.008). The level of IL-10 correlated positively with the advanced stage of disease estimated according to the Salmon and Durie classification (I versus III stage - p = 0.03). Higher values of IL-10 were found in patients with the light chain disease, hypercalcaemia, and correlated with the elevated concentrations of C-reactive protein (CRP). IL-6 was detected in 117 of the 121 patients and in all controls. The concentration of IL-6 was statistically increased in MM patients compared with control group (mean - 16.06 and 4.49 pg/ml, respectively) (p = 0.01). We found a positive correlation between IL-10 and IL-6 serum levels in MM patients. The relationship, expressed as Spearman's rank sum coefficient (rho = 0.249, p = 0.006) was significant. IL-11 was detected in 26 of the 121 MM patients and in 3 of the 28 healthy subjects at the mean concentration of 1.2 and 0.6 pg/ml respectively (p > 0.05). OSM was at detectable levels in 51 of the 121 patients and in only 4 of the 28 controls (mean - 3.84 and 0.1 pg/ml, p = 0. 002). The correlation between IL-10 and IL-11 levels in MM patients was not significant, but there was a strong statistical correlation between IL-10 and OSM concentrations (rho= 0.327, p = 0.0002). The serum concentration of sIL-6R was measurable in all patients and all controls (mean - 66.00 and 39.57 ng/ml respectively), but the difference between these groups was not significant. We found significant, positive correlation between the levels of IL-10 and sIL-6R (rho= 0.233, p = 0.01). In conclusion, we state that the serum concentrations of IL-10, IL-6, OSM and sIL-6R in MM patients may be a useful markers for the evaluation of the disease activity.     

Markers of inflammation are inversely associated with VO2 max in asymptomatic men.

We investigated whether markers of inflammation, including a cytokine (IL-6), acute-phase reactants [C-reactive protein (CRP) and fibrinogen], and white blood cell (WBC) count are associated with maximal O(2) consumption (Vo(2 max)) in men without coronary heart disease (CHD). In asymptomatic men (n = 172, 51 +/- 9.3 yr old), Vo(2 max) was measured during a symptom-limited graded treadmill exercise test. Physical activity level was assessed by a standardized questionnaire. IL-6 and CRP were measured by immunoassays, fibrinogen by the Clauss method, and WBC count with a Coulter counter. IL-6 and CRP were logarithmically transformed to reduce skewness. Multivariable regression was used to assess whether markers of inflammation were associated with Vo(2 max) after adjustment for age, body mass index, CHD risk factors, and lifestyle variables (physical activity level, percent body fat, and alcohol intake). Vo(2 max) was 34.5 ml.kg(-1).min(-1) (SD 6.1). Log IL-6 (r = -0.38, P < 0.001), log CRP (r = -0.40, P < 0.001), fibrinogen (r = -0.42, P < 0.001), and WBC count (r = -0.22, P = 0.004) were each correlated with Vo(2 max). In separate multivariable linear regression models that adjusted for age, body mass index, CHD risk factors, and lifestyle variables, log IL-6 [beta-coeff = -1.66 +/- 0.63 (SE), P = 0.010], log CRP [beta-coeff = -0.99 +/- 0.33 (SE), P = 0.003], fibrinogen [beta-coeff = -1.51 +/- 0.44 (SE), P = 0.001], and WBC count [beta-coeff = -0.52 +/- 0.30 (SE), P = 0.088] were each inversely associated with Vo(2 max). In conclusion, higher circulating levels of IL-6, CRP, and fibrinogen are independently associated with lower Vo(2 max) in asymptomatic men.     

The involvement of IL-6 and IL-8 in acute invasive gastroenteritis of children

The involvement of the proinflammatory cytokines, interleukin 8 (IL-8) and 6 (IL-6), was studied during the first 72 h of acute invasive gastroenteritis. Study population included 33 infants and young children aged six months to six years and seven age-matched controls. As a group, patients with acute invasive gastroenteritis had an increased serum level of IL-8 and IL-6 as compared with healthy controls (p < 0.002 and p < 0.001, respectively). Subjects were then divided into two groups based on stool cultures (proven and non-proven bacterial cultures). Patients with bacterial-proven acute invasive gastroenteritis tended to have increased IL-8 serum concentrations (p < 0.07) as compared with those with non-proven bacterial etiologies and IL-6 levels were only detected in subjects with positive bacterial cultures (p < 0.05). When dividing each sub-group into early and late blood drawing with respect to disease onset, no statistical differences were found in each group but subjects with bacterial-proven etiologies had significant higher IL-6 levels as compared with non-proven etiologies at the two time points (p < 0.019 and p < 0.015, respectively).In conclusion, the proinflammatory cytokines, IL-6 and IL-8, are involved in acute invasive gastroenteritis. The difference in IL-6, and to a lesser degree IL-8, between proven and non-proven bacterial etiologies, needs further investigation.     

全髋关节置换术用于股骨颈骨折患者的临床疗效评价及对血清OPG、BGP、ALP、CRP、IL-6的影响

目的:分析全髋关节置换术用于股骨颈骨折患者的临床效果及对血清骨保护素(OPG)、骨钙素(BGP)、碱性磷酸酶(ALP)、C反应蛋白(CRP)、白细胞介素-6(IL-6)的影响。方法:选择我院2014年3月~2016年3月收治的102例股骨颈骨折患者,按抽签法分为对照组与研究组,每组各51例。对照组采用半髋关节置换术治疗,研究组采用全髋关节置换术治疗。比较两组的临床疗效,治疗前后Harris评分、血清OPG、BGP、ALP、CRP、IL-6水平的变化及术后并发症的发生情况。结果:治疗后,研究组的优良率显著高于对照组(P0.05);两组Harris评分、血清OPG、BGP、ALP、CRP、IL-6水平均较治疗前显著上升,且研究组Harris评分显著高于对照组(P0.05),而两组OPG、BGP、ALP、CRP、IL-6水平比较差异无统计学意义(P0.05)。结论:全髋关节置换术用于股骨颈骨折的临床效果肯定,虽可引起血清OPG、BGP、ALP、CRP、IL-6水平上升,但未增加手术风险。     

Hormonal modulation of interleukin-6, tumor necrosis factor and associated receptor secretion in postmenopausal women

Hormone replacement therapy (HRT) reduces the risk for osteoporosis but transiently increases cardiovascular risk for some postmenopausal women. This study investigated the hypothesis that these risks are associated with HRT-induced changes in mononuclear cell secretion of interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-alpha), and associated soluble receptors. Compared to the untreated condition (n=8), estrogen therapy (n=7) and estrogen+progestin therapy (n=7) both caused 2-fold elevations in TNF-alpha secretion. IL-6 secretion was increased (48%, P=0.04) only by estrogen+progestin therapy. Although soluble receptor secretion was not different among groups, soluble TNF receptor type I and IL-6 receptor secretion were inversely related to plasma follicle stimulating hormone (P<0.05). Both therapies reduced plasma osteocalcin (a marker for osteoporosis) by approximately 50% (P<0.002). Plasma C-reactive protein (CRP, a marker for cardiovascular risk) was 3-fold higher in women receiving only estrogen, compared to untreated women (P=0.01), and twice as high as those receiving estrogen+ progestin (P=0.045). Simple linear relationships were not observed between cytokine secretion and these markers, but a significant HRT/TNF-alpha interaction with osteocalcin (P=0.022) and an HRT/IL-6 interaction with CRP (P =0.016) indicated more complex relationships between hormone replacement, cytokine activity, and health risks associated with menopause.     

鼻炎患者血清中IL-27、IL-17、IL-10在变应性的表达及临床意义

目的:探讨鼻炎患者血清中白细胞介素-27(IL-27)、白细胞介素-17(IL-17)、白细胞介素-10(IL-10)在变应性中的表达以及临床意义。方法:选取2013年5月到2014年5月我院收治的变应性鼻炎患者60例为研究组,另外选取健康志愿者60例为对照组,应用酶联免疫吸附试验(ELISA)检测入选者血清中的IL-27、IL-17以及IL-10的表达情况,并分析其相关关系。结果:研究组血清中IL-27、IL-10水平显著低于对照组,差异具有统计学意义(P0.05);研究组IL-17水平显著高于对照组,差异具有统计学意义(P0.05);研究组患者血清中的IL-27和IL-17呈负相关关系(r=-0.372,P=0.035),IL-27和IL-10呈正相关关系(r=0.524,P=0.026),而IL-17和IL-10无相关关系(r=0.519,P=0.318)。结论:变应性鼻炎患者中IL-27和IL-10呈低表达,而IL-17呈高表达,IL-27可能对IL-17和IL-10具有免疫调节的作用。     

Serum and urine levels of interleukin-6 and interleukin-8 in children with acute pyelonephritis

Urinary tract infection (UTI) is a common clinical disorder in younger infants and children and may result in permanent renal damage. The inflammatory cytokines interleukin (IL)-6 and IL-8 play an important role in response to bacterial infection. This prospective study investigated the association between serum and urine IL-6 and IL-8 levels and acute pyelonephritis confirmed by (99m)Tc-dimercaptosuccinic acid (DMSA) scan. A total of 78 children aged 1-121 months with a diagnosis of first-time febrile UTI were included. The following inflammatory markers were assessed: fever; white blood cells count (WBC); C-reactive protein (CRP); and serum and urine IL-6 and IL-8. The patients were divided into the acute pyelonephritis group (n=42) and the lower UTI group (n=36) according to the results of DMSA scan. Fever, WBC and CRP levels were significantly higher in children with acute pyelonephritis than in those with lower UTI (all p <0.001). Significantly, higher initial serum and urine IL-6 and IL-8 levels were found in children with acute pyelonephritis than in those with lower UTI (all p <0.001). Serum and urine IL-6 in children with acute pyelonephritis were positively correlated with fever, CRP and leucocyturia. These results indicate that both serum and urine IL-6 and IL-8 levels, particularly IL-6, are useful diagnostic tools for early recognition of acute pyelonephritis in febrile children.     

Measurement of gp130 cytokines oncostatin M and IL-6 in gingival crevicular fluid of patients with chronic periodontitis

Several proinflammatory cytokines can induce periodontal tissue destruction and are thought to be useful indicators or diagnostic markers for periodontitis. Here, we aimed to investigate whether oncostatin M (OSM) was present in gingival crevicular fluid (GCF) and to clarify the correlation of GCF OSM and interleukin-6 (IL-6) levels with the severity of periodontitis. Sixty-two sites in 14 patients were divided into 4 groups based on probing depth (PD) and bleeding on probing (BOP). GCF was collected using paper strips from clinically health sites (PD < or = 3 mm, CAL: 1-3 mm, without BOP, n = 31), mildly diseased sites (PD < or = 3 mm, CAL: 3-5 mm, with BOP, n = 11), moderately diseased sites (PD = 4-6 mm, CAL: 5-8 mm, with BOP, n = 11), and severely diseased sites (PD > 6 mm, CAL: 8-12 mm, with BOP, n = 9). IL-6 and OSM in GCF were quantified by enzyme-linked immunosorbent assay and are expressed as concentrations (pg/ml) and total amounts (pg/site). Correlations of OSM and IL-6 levels with the severity of periodontitis in all groups were determined using Spearman rank correlation (r(s)). Our results showed that OSM and IL-6 were detected in most GCF samples. The total amounts of OSM and IL-6 were significantly positive correlated with severity of diseased sites (OSM: r(s) = 0.526, p < 0.01; IL-6: r(s) = 0.729, p < 0.01). No correlations of OSM or IL-6 concentration in GCF were found with disease severity. OSM and IL-6 levels in GCF were positively correlated to each other when expressed as either concentrations or total amounts (concentrations: r = 0.485, p < 0.01; total amounts r = 0.490, p < 0.01). In conclusion, our findings suggest that IL-6 and OSM may play a role in modulating the inflammatory cascade of chronic periodontitis.     

经腹次全子宫切除术治疗子宫肌瘤的临床效果及对血清VEGF，IL-6，IL-8水平的影响

目的:探讨经腹次全子宫切除术治疗子宫肌瘤的临床效果及对血清血管内皮生长因子(VEGF)、白细胞介素-6(IL-6)、白细胞介素-8(IL-8)水平的影响。方法:选择我院2014年2月~2016年2月收治的106例子宫肌瘤患者,参照抽签法分作对照组与研究组。对照组采用经腹全子宫切除术治疗,研究组采用经腹次全子宫切除术治疗。比较两组的手术时间,出血量,肛门排气时间,住院时间,手术前后VEGF、IL-6、IL-8、促卵泡生成素(FSH)、雌二醇(E2)、抗苗勒管激素(AMH)水平的变化及并发症的发生情况。结果:研究组的手术时间、出血量、肛门排气时间、住院时间均明显短于对照组(P0.05)。手术前,两组血清VEGF、IL-6、IL-8、FSH、E2、AMH水平比较差异无统计学意义(P0.05);手术后,研究组血清IL-6、IL-8、E2、AMH水平明显低于对照组(P0.05),血清FSH水平明显高于对照组,差异具有统计学意义(P0.05),两组血清VEGF水平比较差异无统计学意义(P0.05)。研究组并发症的发生率显著低于对照组(P0.05)。结论:采用经腹次全子宫切除术治疗子宫肌瘤患者可起到与经腹全子宫切除术相似的应用效果,但经腹次全子宫切除术对机体形成的创伤较小,利于术后卵巢功能的恢复,可能与其降低患者术后血清IL-6、IL-8、VEGF水平有关。
