The plasma levels of inflammatory cytokine interleukin-6 (IL-6) and anti-inflammatory cytokine interleukin-10 (IL-10) in the patients with unstable angina or stable angina were determined and compared. In 30 patients with unstable angina and 22 patients with stable angina, plasma levels of IL-10 and IL-6 were detected by ELISA and plasma lipid parameters by lipid research clinical methods respectively. The results showed plasma levels of IL-10 were significantly lower in unstable angina group than in stable angina group (P = 0.005), while those of IL-6 were significantly increased in unstable angina group as compared with those in stable angina group (P = 0.039). There was a significantly negative correlation between IL-10 and IL-6 in patients with unstable angina (r = -0.41, P = 0.003). In the unstable angina group, IL-6 levels were obviously positively correlated with TC (r = 0.314, P = 0.023), but not with TG and HDL. There were no significant correlations between IL-10 and plasma lipid parameters. It was suggested that the decreased IL-10 and increased IL-6 might be associated with the atheromatous plaque stability and progression of coronary heart diseases. IL-10 may play an important role in preventing coronary vascular lesions.

OBJECTIVETo explore the clinical effects of combined slower plasma exchange (PE) and continuous veno-venous hemofiltration (CVVH) with a parallel circuit in the treatment of chronic severe viral hepatitis B patients.

METHODS104 patients with chronic severe viral hepatitis B were divided into three groups: 44 patients were treated with a parallel circuit of combined slower plasma exchange and continuous veno-venous hemofiltration (group A), 30 patients were treated with plasma exchange (group B), and 30 patients received routine treatment (group C). Efficacy of treatment and survival rate in three groups were investigated. The levels of cytokine, plasma sodium concentration and pH value were examined before and after artificial liver support system treatment.

RESULTSIn group A, 7 of 9 patients in coma regained normal consciousness, 6 of 9 patients with hepatorenal syndrome restored renal function, hyponatremia was improved, the balance of pH value was corrected, tumor necrosis factor (TNF)-alpha level was decreased, and the total survival rate was 56.82%. In group B, 2 of 7 patients in coma regained normal consciousness, 1 of 5 patients with hepatorenal syndrome restored renal function. Hyponatremia, pH value and TNF-alpha level were not changed; the total survival rate was 33.33%. Both IL-1 and IL-6 levels were significantly decreased after treatment in group A. IL-10 level was increased in both group A and group B. In group C, 1 of 6 patients regained normal consciousness from coma, none of them restored renal function, and the total survival rate was 16.67%.

CONCLUSIONSCombined slower PE and CVVH with a parallel circuit is a new, safe and effective non-biological artificial liver in the treatment for chronic severe viral hepatitis B patients.

OBJECTIVETo evaluate the changes in the expressions of the inflammatory cytokines (IL-1, IL-2, IL-6 and IL-10) in blood serum of the patients after total hip replacement (THR).

METHODSFrom February 2010 to June 2010, thirty patients undergone primary total hip arthroplasty in one side including 18 male and 12 female with the mean age of (58.4 +/- 6.6) years (ranged from 52 to 70 years). Twenty patients were Ficat II type,and 10 patients were Ficat III type. The contents of IL-1, IL-2, IL-6 and IL-10 in blood serum were detected on the day before operation and 1 to 3 days after operation respectively by ELISA. At the same time, the content of C reactive protein was also detected, and the results were statistically analyzed.

RESULTSThe contents of IL-1, IL-6 and IL-10 in the serum of patients at the first day after THR were significantly higher than those before operation (t = 2.62, 3.51, 2.21, P < 0.05), and reached the peak at 1 to 3 days after operations, then subsequently decreased. However, the content of IL-2 in the serum of patients after operation was obvious lower (t = 2.16, P < 0.05),and recovered to normal level gradually.

CONCLUSIONIt is the key time of treatment at 1 to 3 days after THR. Monitoring IL-1, IL-2, IL-6 and IL-10 after operation in time, and monitoring life sign at the same time could sensitively observe the effect of treatment and forecast the trend of diseases in patients.

OBJECTIVETo investigate the influence of continuous renal replacement therapy (CRRT) on the plasma levels of endotoxin and cytokines in severely burned patients with sepsis.

METHODSTen burn patients who received CRRT and another 10 without CRRT were investigated in terms of the changes in their plasma concentrations of endotoxin and some cytokines (TNFalpha, IL-1beta, IL-6, IL-8).

RESULTSThe plasma concentrations of endotoxin and all the cytokines (TNFalpha, IL-1beta, IL-6, IL-8) after CRRT treatment were significantly lower than those before the treatment (P < 0.01), and the plasma levels of the above factors at all the time points after CRRT treatment than those in patients were evidently lower by routine treatment (P < 0.05 - 0.01).

CONCLUSIONCRRT treatment could effectively lower the plasma levels of endotoxin and some cytokines (TNFalpha, IL-1beta, IL-6, IL-8).

To explore influence of platelet donation on donor's megakaryocytopoiesis, platelet counts and plasma concentrations of thrombopoietin (TPO), interleukin-3 (IL-3), IL-6 and nitric oxide (NO) were determined in 42 frequent platelet donors (undergoing plateletpheresis more than once a month for 24 months and their mean platelet yield of collection was 2.5 x 10(11)), in 62 limited platelet donors (undergoing plateletpheresis less than once a month for 24 months) after a donation-free period of > 5 weeks and in 40 whole blood donors who never undergoing plateletpheresis after a donation-free period of > 6 months. The results showed that the TPO levels was significantly lower in frequent platelet donors than in limited platelet donors (P < 0.01) and whole blood donors (P < 0.01). There were no significant differences between three groups in platelet counts, IL-3, IL-6 and NO. These findings suggest that the number of megakarocytes significantly increased in frequent platelet donors.

OBJECTIVETo explore the significance of interleukin-6 (IL-6) and IL-8 in the diagnosis of neonatal sepsis.

METHODSThis was a prospective study conducted between August 2014 and February 2015. A total of 140 neonates who were suspected infectious were enrolled and classified into a sepsis group (n=49) and a local infection group (n=91). Sixty-one neonates who were non-infectious served as the control group. Serum levels of IL-6 and IL-8 were measured before treatment and 3 days after treatment. The value of serum IL-6 and IL-8 for the diagnosis of neonatal sepsis was assessed by receiver operating characteristic (ROC) curve analysis.

RESULTSBefore treatment, serum levels of IL-6 and IL-8 in the sepsis group were higher than those in the local infection and control groups (P<0.05), and the local infection group had higher serum levels of IL-6 and IL-8 than the control group (P<0.05). After three days of treatment, the serum IL-6 level in the sepsis group remained higher than that in the local infection and control groups (P<0.05), and the local infection group had higher serum level of IL-6 than the control group (P<0.05). There was no significant difference in the serum IL-8 level among the three groups. According to the ROC curve, when the cut-off value of serum IL-6 was 32 pg/mL, the sensitivity, specificity and accuracy of serum IL-6 for the diagnosis of neonatal sepsis were 87.8%, 79.6% and 81.6% respectively; when the cut-off value of serum IL-8 was 54 pg/mL, the sensitivity, specificity and accuracy of serum IL-6 for the diagnosis of neonatal sepsis were 77.6%, 63.8% and 67.2% respectively. With the combination of serum IL-6 and IL-8 levels, the sensitivity, specificity and accuracy for the diagnosis of neonatal sepsis were 71.4%, 86.2% and 82.6% respectively.

CONCLUSIONSIL-6 and IL-8 participate in the inflammatory response and the serum levels of both vary with the severity of infection. The diagnostic value of IL-6 for neonatal sepsis is higher than IL-8. The combined detection of serum levels IL-6 and IL-8 may increase the accuracy of diagnosis of neonatal sepsis.

OBJECTIVETo identify the differential expressions of serum cytokines between prostate cancer (PCa) and benign prostatic hyperplasia (BPH), and provide proteomic evidence for the early diagnosis of PCa.

METHODSWe used human cytokine array to determine the profiles of the serum cytokines obtained from 6 PCa and 6 BPH patients with the PSA level within the grey scale of 4 - 10 ng/ml.

RESULTSWe identified 19 differentially expressed cytokines in the PCa patients, 16 obviously up-regulated, including IL-3, IL-6 and IL-16, and 3 markedly down-regulated, which were Fas/TNFRSF6, TRALR-3 and IGFBP-6. Most of them were involved in such cellular bioprocesses as transcription, proliferation, signal transduction, and apoptosis.

CONCLUSIONThe cytokine antibody assay permits simultaneous measurement of multiple markers in a small volume of serum, and can identify a panel of key cytokines related to the malignant biological behavior of cancer cells. And it helps to find the biomarkers for the early diagnosis, efficacy assessment and prognosis of prostate cancer.

OBJECTIVETo investigate the effects of prostaglandin E1 (PGE1) on the cytokines (IL-6, IL-8, IL-10) levels and ischemic -reperfusion injury of myocardium during cardiac surgery.

METHODSA total of 30 patients undergoing cardiac surgery (mitral valve replacement) under extracorporeal circulation were randomized into two groups: PGE1 group (receiving 0.04 microg.kg(-1). min(-1) of Lipo-PGE1 from the beginning of surgery to the end of study, n=15) and control group (no PGE1 given, n=15). Levels of serum IL-6, IL-8 and IL-10 were measured by enzyme-linked immunosorbent assays (ELISA). Isoenzyme of creatine kinase with muscle and brain subunits(CKMB) and troponin-T (cTn-T) were measured by ultraviolet absorption spectrophotometry method and enzyme immunoassay on 5 time-points during the study.

RESULTIn both groups serum IL-6, IL-8, CK-MB and cTn-T levels increased significantly after aorta declamping (especially from 2 h after aorta declamping) compared with preoperative levels (P<0.05).However,the elevations of these cytokines and enzymes were more prominent in the control group than in the PGE1 group (P<0.05). Serum IL-10 concentration increased significantly from 2 h after aorta declamping compared with preoperative value (P<0.05); but there were no differences between the two groups. IL-6 and IL-8 levels were correlated with CK-MB and cTn-T concentrations (r2=0.40, r2=0.38 P>0.05 and r2=0.56, r2=0.14; P>0.05, respectively).

CONCLUSIONDuring cardiac surgery (mitral valve replacement) PGE1 may suppressed the production of IL-6, IL-8 but not IL-10, which may be related to its myocardial protection effect.

AIMTo observe effect of acute normovolemic hemodilution(ANH) with HAES-balanced solution as diluting agent on levels of cytokines including IL-1, IL-2, IL-6 and TNF-alpha in rabbit serum so as to provide theoretical basis for clinical application.

METHODSA total of 20 healthy adult rabbits were enrolled in the study and randomly divided into two groups (10 rabbits per group), i.e., control group (Group C) and HAES group (Group H). Under anesthesia of the rabbits, we performed incision of trachea, high-frequency jet ventilation and liberation of femoral artery and femoral veins. Group C was free from hemodilution. Group H was injected with dilution (2-fold of blood letting volume) via femoral veins during blood letting of the femoral artery. 6% HAES-steril plus compound solution of sodium lactate, with crystal/gel ratio of 2:1, blood letting volume = TBV x (Ho-Hf)/Hav. All blood was transfused back 60-120 min after blood letting. Venous blood was collected before blood letting (T0) and 30 min (T1), 60 min (T2), 120 min (T3) and 24 h(T4) after blood letting to detect Hb and Hct and measure level of IL-1, IL-2, IL-6 and TNF-alpha in serum.

RESULTSIn Group H, levels of IL-1, IL-2, IL-6 and TNF-alpha in serum were increased from T1 after ANH, reached peak at T3 but showed decrease at T4, with significant difference compared with Group C at T1, T2, T3 and T4 (P < 0.01) and significant difference compared with those before ANH (P <0.01). In Group C, there was no significant difference upon IL-1, IL-2, IL-6 and TNF-alpha in serum at different time points.

CONCLUSIONANH with HAES-balanced solution as diluting agent can up-regulate the levels of cytokines IL-1, IL-2, IL-6 and TNF-alpha in rabbit serum. In the meantime, ANH may arouse eustress with low intensity and short action time, which exerts effect of enhancing immune function of the organisms.

OBJECTIVETo observe the effect of electroacupuncture (EA) on cytokines in the cardiac surgical patient and to evaluate the application of combined acupuncture anesthesia to cardiac surgery.

METHODSThirty patients with atrial septal defect were divided into 3 groups, general anesthesia group (A), acupuncture anesthesia group (B) and combined general anesthesia and EA group (C). Peripheral blood samples were collected before anesthesia, before cardiopulmonary bypass (CPB), 30 min after CPB and 24 h after operation to determine the levels of interferon-gamma (IFN-gamma), interleukin-2 (IL-2), IL-6 and IL-10.

RESULTSThe levels of IFN-gamma and IL-2 decreased in the 3 groups after CPB and further decreased 24 h after operation, and in the group C were higher than those in the group B. The levels of IL-6 and IL-10 significantly increased 24 h after operation in the 3 groups with no significant difference among the 3 groups.

CONCLUSIONThe general anesthesia combined with EA can not completely improve the decrease of IFN-gamma and IL-2 induced by CPB, indicating that the good response of the general anesthesia combined with EA to stress can partially improve the immunosupression induced by CPB. Acupuncture does not have significant effect on inflammatory cytokine reaction induced by cardiac surgery.
