Interleukin-1 (IL-1), interleukin-2(IL-2) and interleukin-6(IL-6) activities and tumor necrosis factor (TNF) contents in plasma from patients with different sites of cancers as well as controls using bioassay technique were studied. The results showed that the levels of IL-1,IL-2,IL-6 s from patients with different sites of cancer were decreased remarkably in comparision with controls and the contents of TNF from patients with different sites of cancers increased significantly. But the difference between different sites of cancer was not statistically significant. The data suggest that the variations in the contents of TNF and the levels of interleukins may be related to the development of these caner patients.
目的 探讨脂多糖（LPS）、白细胞介素-6（IL-6）和血小板活化因子（PAF）与重症胸腹创伤后凝血功能紊乱发生的相关性及可能的致病机理。方法 收集2009年1月至2011年12月期间在中国人民解放军第二五三医院急诊科就诊、创伤指数≥17分且除外合并颅脑损伤及在急诊科内死亡的胸腹创伤患者62例，在予以抢救、治疗的同时抽血检查血小板计数（PLT）、血浆D-二聚体（D-D）、部分活化凝血酶原时间（APTT）、凝血酶原时间（PT）、LPS、IL-6和PAF，并对其结果进行相关性分析。结果 本组患者就诊时检测的PLT为（157.73±78.11）×109/L， D-D为（1 023.88±208.72） U/L，APTT为（46.95±17.85） s，PT为（19.44±6.95） s，TT为（58.27±12.44）s，除PLT降低外，其余4项指标均升高或延长； LPS为（322.85±104.54） U/L，IL-6为（285.51±81.46） ng/mL，PAF为 （14 714.70±4 427.95） ng/L， 三者均升高； PLT与LPS、IL-6和PAF之间呈负相关关系（P＜0.001），而D-D、APTT、PT和TT与LPS、IL-6和PAF之间均呈正相关关系（P＜0.001）。结论 LPS、IL-6及PAF可能参与了重症胸腹创伤后凝血功能障碍的发生；重症胸腹损伤后出现的微循环障碍及内毒素血症是凝血功能障碍发生的重要机理。针对LPS、IL-6和PAF进行早期干预，有可能改善重症胸腹创伤患者的凝血功能障碍。
【Abstract】ObjectiveTo investigate the effect of Salvia Miltiorrhiza (SM) and Shengmai injection （SI） in treating systemic inflammatory response syndrome (SIRS) and their mechanism. Methods The animal model of SIRS was established by injectinglipopolysaccharide(LPS, 1 mg/kg)intraperitoneally. Forty Wistar rats were randomly divided into four groups: control group, SM group, SI group and combined treatment group (SM+SI group), which were treated with normal saline（5 ml/kg） plus LPS（1 mg/kg）, SM（5 ml/kg）plus LPSKG4（1 mg/kg）, SI（5 ml/kg）plus LPS（1 mg/kg）, SM（2.5 ml/kg） plus SI（2.5 ml/kg） and LPS（1 mg/kg） respectively. Six rats of each group were sacrificed for sample collection of blood, liver, lung and kidney 8 hours after LPS injection. Blood routine, serum TNF-α and IL-6 were measured. Specimen of organs were fixed in formalin and sent for routine pathological examination. The survival of other 4 rats of each group were observed untill 48 hours after LPS injection. SPSS 10.0 was used in statistical analysis. Results Two rats in control group died 13 hours and 22 hours after LPS injection respectively, the remaining 2 rats in this group and the rats in other 3 groups survived 48 hours after LPS injection. The white blood cell count of control group was significantly higher than that of other groups. The serum TNF-α and IL-6 of control group were significantly more than those of other groups. Pathological damages were found in all groups, and the most severe ones were in control group. SM and SI could decrease the level of serum TNF-α and IL-6 in the process of LPS-stimulated SIRS, down-regulate the severe inflammatory response, attenuate organ damages of the liver, lung and kidney, and increase forty-eihgt-hour survival rate obviously. Conclusion The experiment provides a theoretical base for clinical use of SM and SI in treatment of SIRS.
ObjectiveTo investigate the correlation between tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), phospholipase A2 (PLA2) and myocardial cell function disorders in severe chest-abdominal injury patients. MethodsEighty-two subjects with severe chest-abdominal injury were collected from January 2009 to June 2012, of whom the trauma index were all above or equal to 17 points. As the rescue and treatment were in progress, the patients were examined for their creatine kinase-MB (CK-MB), cardiac troponin T (cTnT), TNF-α, IL-6, and PLA2 for correlation analysis. Another 82 subjects undergoing physical examination during the same time were chosen as the controls, who were again divided into myocardial cell function control group with 46 subjects and injury factors control group with 36 subjects. ResultsFor the myocardial cell function control group, CK-MB was (8.13±3.64) U/L, and cTnT was (26.71±11.58) pg/mL; for the injury group, those two indexes were respectively (158.74±31.59) U/L and (496.25±58.46) pg/mL. For the injury factors control group, TNF-α was (1.28±0.59) ng/mL, IL-6 was (63.93±41.49) ng/mL, and PLA2 was (7.47±5.27) ng/mL; for the injury group, those three indexes were respectively (36.41±18.09) ng/mL, (393.83±143.86) ng/mL, and (41.35±14.26) ng/mL. For severer chest-abdominal injury patients, all correlation factors between CK-MB and TNF-α, IL-6, PLA2 were above 0.911, and the factors between cTnT and TNF-α, IL-6, PLA2 were all above 0.912, and all correlations were positive. ConclusionTNF-α, IL-6 and PLA2 all participate in the process of acute myocardial cell function disorders in severe chest-abdominal injury patients. Early intervention of TNF-α, IL-6, and PLA2 may reduce myocardial cell damage, and improve patients' survival rate.
ObjectiveTo discuss the effects of coix seed extract injection on rate of tumor of C57 mice liver cancer model, tumor size, and serum IL-6. MethodsUsing chemical carcinogens diethyl nitrosamine (DEN) to establish the mice model of liver cancer, liver cancer mouse model to coix seed extract was given observation of C57 mice liver cancer model come tumor formation rate, tumor growth, and the change of serum IL-6. ResultsC57 mice after intraperitoneal injection of coix seed extract injection model of liver cancer tumor rate (55.6%) significantly lower than the DEN group (87.5%), P < 0.01; tumor diameter[(0.3±0.05) cm] was lower than that in group DEN[(0.8±0.06) cm], P < 0.01. The serum level of IL-6 in C57 mice after treated with coix seed extract significantly lower than that in group DEN (P < 0.01). ConclusionCoix seed extract can effectively inhibit the tumor rate and the growth of tumor in hepatocellular carcinoma model of C57 mice, and decrease the level of serum IL-6.
Objective To explore the correlation between interleukin-6 (IL-6) 174G/C polymorphism and ischemic stroke risks. Methods Systematic searches of electronic databases as CBM, CNKI, PubMed, MEDLINE and EMbase were performed. Meta-analysis was conducted by using RevMan 5.1.2 and Stata 11.0 software. The pooled odds ratios (ORs) with 95% confidence intervals (95%CIs) were performed. Publication bias was tested by funnel plot, Egger’s regression test and Begg’s test. Sensitivity analysis was made by repeating the fixed effects model or random effects model Meta-analysis with each of the studies individually removed. Results A total of 11 publications with 12 studies were identified. The results of meta-analyses showed no significant difference was found in the correlation between IL-6 174G/C polymorphism and ischemic stroke risks (for G/C vs. G/G: OR=0.98, 95%CI 0.78 to 1.24; for C/C vs. G/G: OR=0.75, 95%CI 0.38 to 1.50; for dominant inheritance model: OR=0.93, 95%CI 0.68 to 1.28; for recessive inheritance model: OR=0.80, 95%CI 0.45 to 1.42). In the subgroup analyses on ethnicity, no significant correlation was found. But in the subgroup analyses on source of control population, the hospital-based subgroup showed IL-6 174G/C polymorphism was the protective factor of ischemic stroke (for G/C vs. G/G: OR=0.56, 95%CI 0.40 to 0.79; for C/C vs. G/G: OR=0.17, 95%CI 0.11 to 0.27; for dominant inheritance model: OR=0.40, 95%CI 0.29 to 0.55; for recessive inheritance model: OR=0.24, 95%CI 0.16 to 0.37). Conclusion Meta-analysis bly suggests that the correlation between IL-6 174 G/C polymorphism and ischemic stroke is not significantly different.
ObjectiveTo investigate the correlation of synovial fluid uric acid, the serum and synovial fluid interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α with knee osteoarthritis (KOA). MethodsThe clinical data of 130 patients with KOA treated between January and December 2013 and 30 patients with gouty arthritis (GA) treated at the same period were collected. The clinical symptoms, Western Ontario and McMaster Universities Osteoarthritis Index score, the serum and synovial fluid IL-1β, IL-6, and TNF-α, uric acid levels, radiographic joint stenosis score, and bone hyperplasia score of the patients were compared using t-test analysis and Spearman correlation analysis. ResultsIn the KOA group, the synovial fluid uric acid and joint stenosis score (r=0.31, P=0.037), bone hyperplasia score (r=0.38, P=0.027) were positively correlated; serum and synovial fluid uric acid gradient and hypnalgia were positively correlated (r=0.34, P=0.031); the synovial fluid IL-6 and joint stenosis score (r=0.33, P=0.029), bone hyperplasia score (r=0.37, P=0.032) were positively correlated; the synovial fluid IL-1β and joint stenosis score (r=0.39, P=0.023), bone hyperplasia score (r=0.34, P=0.034) were positively correlated; and the synovial fluid uric acid and IL-1β (r=0.26, P=0.003), IL-6 (r=0.21, P=0.016) were positively correlated. ConclusionSynovial uric acid, IL-1β and IL-6 play a role in the inflammatory progress of knee osteoarthritis.
