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.

BACKGROUNDSeveral studies investigating the prognostic utility of interleukin-10 (IL-10) in patients with acute coronary syndrome (ACS) have provided conflicting findings. The aim of the study was to assess the existing evidence regarding association between serum IL-10 levels and adverse events.

METHODSLiterature search was performed in PubMed, EMBASE, and Cochrane Trials Register databases from their inception to September 30, 2012. In addition, reference lists of the included articles and their related citations in PubMed were also reviewed for additional pertinent studies.

RESULTSA total of 12 eligible studies comprising a total of 5882 patients were identified. The pooled relative risks for both studies reporting the risk estimates by IL-10 categories and studies reporting the risk estimates by unit IL-10 indicated an association between high IL-10 levels and adverse events. Sensitivity and subgroup analysis indicated that the results obtained in IL-10 categories were not stable.

CONCLUSIONSData from our meta-analysis supported the existence of a relationship between high serum IL-10 levels and adverse events in patients with ACS. Large study with longer follow-up is needed to confirm the findings.

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.

To investigate the level of serum IL-10 in allergic rhinitis patients and the correlation between IL-10 and serum total IgE (TIgE). 50 allergic rhinitis patients and 30 normal subjects were involved in the study. The levels of serum IL-10 and TIgE were measured by enzyme-linked immunosorbent assay (ELISA), and the correlation between serum IL-10 and TIgE was analyzed. In the allergic rhinitis group, the levels of serum IL-10 and TIgE were 8.34 +/- 2.48 pg/mL and 142.6 +/- 28.2 KU(A)/L. In the normal control group, they were 12.86 +/- 2.88 pg/mL and 47.2 +/- 12.2 KU(A). There were significant differences between the two groups (P < 0.01); and the level of serum TIgE in the patients was negatively correlated with that of IL-10 (r = -0.46, P = 0.02). The level of serum IL-10 was significantly decreased in allergic rhinitis patients, which was beneficial to the synthesization of IgE. IL-10 plays an important role in the episode of allergic rhinitis.

PURPOSE: Atopic dermatitis is characterized by reduced IFN-gamma production and increased IL-4 production. As a result, IgE production increases in atopic dermatitis. In the previous studies, it was reported that recombinant IFN-gamma therapy is effective in treatment of severe atopic dermatitis. In this study, changes of plasma IFN-gamma, IL-4, IL-5 and IL-10 concentration by IFN-gamma therapy were studied in atopic dermatitis. Changes of plasma IgE levels and eosinophil counts were also investigated in the present report. METHODS: Sixty-five atopic dermatitis patients were studied. Diagnostic criteria for atopic dermatitis were those used by Hanifin and Rajka. Patients received 2x106 units/m2 IFN-gamma by subcutaneous injection eighteen times for six weeks. The following investigations were performed : complete blood cell count, total IgE, eosinophil percentage and total eosinophil count in addition to plasma IFN-gamma, IL-4, IL-5 and IL-10 concentration. RESULTS: Plasma concentrations of IL-4, IL-5 and IL-10 decreased by IFN-gamma therapy in atopic dermatitis. However, plasma IFN-gamma concentration was not changed. No significant correlations among the changes of IgE, eosinophil counts and plasma cytokine concentrations were detected. CONCLUSION: Plasma concentrations of Th2 cytokine such as IL-4, IL-5 and IL-10 decreased by IFN-gamma therapy. This study suggests that Th2 cytokines might not be produced simulaneously. and that changes of Th2 cytokines might not affect the quantitiative changes of IgE and of eosinophil count.

OBJECTIVE: To study the incidence rate of non-thyroidal illness syndrome (NTIS) in critically ill children with or without sepsis and the association of NTIS with interleukin-6 (IL-6) and interleukin-10 (IL-10). METHODS: A retrospective analysis was performed on the medical data of 97 children with sepsis (sepsis group) and 80 non-sepsis children with bacterial infection (non-sepsis group). The correlations of IL-6 and IL-10 with the thyroid function parameters triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH) were analyzed. RESULTS: There were no significant differences in age and sex between the sepsis and non-sepsis groups (P>0.05). Compared with the non-sepsis group, the sepsis group had a significantly higher Sequential Organ Failure Assessment score, a significantly longer length of hospital stay, and a significantly higher rate of use of ventilator (P<0.05). As for inflammation markers, the sepsis group had significantly higher levels of C-reactive protein, procalcitonin, and IL-6 than the non-sepsis group (P<0.05). As for thyroid function parameters, the sepsis group had significantly lower levels of T3, T4, free T3, free T4, and TSH than the non-sepsis group (P<0.05). Compared with the non-sepsis group, the sepsis group had significantly higher incidence rates of NTIS, low T3 and T4, and low TSH (P<0.001). The correlation analysis revealed that IL-6 level was not correlated with T3, T4, and TSH levels in children with or without sepsis (P>0.05), but the pooled analysis of the two groups showed that IL-6 level was negatively correlated with T3 and T4 levels (P<0.001). CONCLUSIONS Children with sepsis have a higher incidence rate of NTIS than those without sepsis. The high level of IL-6 may be associated with the development of NTIS.

OBJECTIVETo study the effects of different models of mechanical ventilation on inflammatory cytokines, IL-6, IL-10 and TNF-alpha, in children after cardiopulmonary bypass (CPB).

METHODSSixty patients who underwent CPB were randomly divided into group A and group B. After CPB, group A was ventilated with high tidal volume (VT, 10-12 mL/kg) /low positive end-expiratory pressure (PEEP, 3-5 cm H2O), while group B was ventilated with low VT (6-8 mL/kg) /high PEEP (6-9 cm H2O). Plasma levels of IL-6, IL-10 and TNF-alpha were measured before operation, at the end of the operation, and 1 and 6 hrs after operation.

RESULTSSerum levels of IL-6, IL-10 and TNF-alpha in both groups increased significantly at the end of the operation and reached a peak by 1 hr after operation. Group B showed lower serum levels of IL-6, IL-10 and TNF-alpha than group A 1 and 6 hrs after operation.

CONCLUSIONSMechanical ventilation with low VT /high PEEP may more effectively inhibit the release of inflammatory cytokines than that with high VT /low PEEP in children after CPB.
