OBJECTIVETo investigate the effect of intravenous lornoxicam (LOR) at different doses given preoperatively on the immune function of patients undergoing total abdominal hysterectomy (TAH).

METHODSForty-five patients undergoing TAH were randomly divided into 3 groups, namely NS group, L8 group and L16 group with intravenous injection of 4 ml saline, 8 mg LOR, and 16 mg LOR before the induction of anesthesia respectively. Venous blood samples were taken before anesthesia (T0), at 30 min during the operation (T1), at the end of the operation (T2), and at 24 h and 48 h after the operation (T3 and T4, respectively) to determine the serum levels of regulated upon activation normal T cell expressed and secreted (RANTES), monocyte chemotactic protein-1 (MCP-1), and stromal cell-derived factor 1 alpha (SDF-1alpha) by enzyme-linked immunosorbent assay (ELISA).

RESULTSThe serum RANTES levels in NS group and L8 group at T1-T3 were significantly lower than those at T0 (P<0.05), but the levels in L8 group at each time point were all higher than those in NS group NS (P<0.05). The serum RANTES levels in L16 group L16 only decreased at T1-T2 as compared to those at T0, and were significantly higher than those in NS group and L8 group (P<0.05). The expressions of MCP-1 and SDF-1alpha in the 3 groups all increased at T1 and reached the peak levels after the operation. In L8 group and L16 group, MCP-1 expression at T2-T3 and SDF-1alpha at T1-T2 were both significantly lower than those in NS group (P<0.05). SDF-1alpha expression at T1-T2 was significantly lower in L16 group than in L8 group (P<0.05). The decrements of MCP-1 and SDF-1alpha were more obvious in L16 group than L8 group.

CONCLUSIONSPreoperative intravenous LOR injection may increase serum RANTES level and decrease MCP-1 and SDF-1alpha expressions to effectively relieve the perioperative immune disorders caused by TAH, and the effect is more potent at the dose of 16 mg.

OBJECTIVETo detect the cytokines levels in serums of patients with trichloroethylene-induced hypersensitivity dermatitis and explore the effect biomarkers associated with this disease.

METHODSTwenty-two patients with TCE-induced hypersensitivity dermatitis, twenty-two healthy TCE-exposed workers from the same workshops with patients and twenty-two comparable unexposed controls were recruited in this study. Eight cytokines in serums from all subjects were detected using Liquid Suspended Biochip; the correlation among the eight cytokines including interleukin (IL)-1β (IL-1β), IL-5, IL-8, IL-10, interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), macrophage chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1β (MIP-1β) and the correlation between IL-5 and eosinophil count were analyzed.

RESULTSThe medians of levels of IL-1β, IFN-γ, IL-5, IL-10, MCP-1, MIP-1β, IL-8 among patients were 0.15, 80.13, 2.95, 6.45, 83.83, 1057.90, 440.22 pg/ml, respectively, which were higher than those among the TCE-exposed workers (0.09, 16.93, 0.11, 0.07, 28.75, 241.07, 28.26 pg/ml, respectively, all P values < 0.01) and unexposed controls (0.09, 3.14, 0.11, 0.07, 25.27, 209.64, 207.34 pg/ml, respectively, all P values < 0.01). The median of level of TNF-α among the patients was 13.26 pg/ml, which was significantly higher than that among TCE-exposed workers (4.87 pg/ml, P < 0.01) but not among unexposed controls; the median of level of IL-5 among the TCE-exposed workers was 0.11 pg/ml, which was significantly higher than that among the unexposed controls (0.11 pg/ml, P < 0.01). The median of levels of IL-8 among the unexposed controls was 207.34 pg/ml, which was significantly higher than that among the TCE-exposed workers (28.26 pg/ml, P < 0.01). In case group, except for correlation of TNF-α and IFN-γ, TNF-α and IL-5, the significant positive correlations were found among any two cytokines (r(IL-1β,IFN-γ) = 0.500, r(IL-1β,TNF-α) = 0.348, r(IL-1β,MCP-1) = 0.537, r(IL-1β,MIP-1β) = 0.477, r(IL-1β,IL-8) = 0.466, r(IL-1β,IL-5) = 0.610, r(IL-1β,IL-10) = 0.626, r(IFN-γ,MCP-1) = 0.460, r(IFN-γ,MIP-1β) = 0.491, r(IFN-γ,IL-8) = 0.322, r(IFN-γ,IL-5) = 0.532, r(IFN-γ,IL-10) = 0.511, r(TNF-α,MCP-1) = 0.325, r(TNF-α,MIP-1β) = 0.283, r(TNF-α,IL-8) = 0.430, r(TNF-α,IL-10) = 0.271, r(MCP-1,MIP-1β) = 0.659, r(MCP-1,IL-8) = 0.526, r(MCP-1,IL-5) = 0.504, r(MCP-1,IL-10) = 0.614, r(MIP-1β,IL-8) = 0.601, r(MIP-1β,IL-5) = 0.451, r(MIP-1β,IL-10) = 0.579, r(IL-8,IL-5) = 0.255, r(IL-8,IL-10) = 0.403, r(IL-5,IL-10) = 0.798, all P values < 0.05). The median of level of IL-5 among the patients with high eosinophils counts was 8.92 pg/ml, which was significantly higher than that among the patients with low eosinophils counts (1.04 pg/ml, P < 0.05).

CONCLUSIONThe abnormal production of IL-1β, IFN-γ, TNF-α, IL-8, MCP-1, MIP-1β, IL-5 and IL-10 was related with the pathogenesis of hypersensitivity dermatitis induced by TCE. These cytokines could be used as referential indexes in the early health surveillance and clinic disease treatment.

This study was purposed to investigate the accumulative regularity of tumor-associated noncellular components in supernatant of stored packed red blood cells (PRBC) during storage. The supernatant of PRBC was obtained by centrifugation with 1 006×g for 10 min at day 0, 7, 14, 21, 28 and 35 d. The enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of T cells and the accumulative levels of secreted RANTES/CCL5, tumor necrosis factor-alpha (TNF-α), platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and monocyte chemotactic protein-1 (MCP-1). The results showed that the high concentration of RANTES/CCL5 and TNF-α was found in fresh PRBC, and their accumulative concentration did not increase along with the prolonging of storage time. The VEGF level in PRBC at day 0 of storage was 229.9 pg/ml, and increased to 749.08 pg/ml at end of day 7, then it was stable, and increased to 760.67 pg/ml at end of day 35. The PDGF level in supernatant of PRBC was 13.54 ng/L at dag 0 of storage, and increased stably during storage, then decreased at day 28, however PDGF rapidly rose to 22.13 ng/L at the end of day 35 (P < 0.05). The MCP-1 level in supernatant of PRBC was 39.98 ng/L at day 0 of storage, then slowly increased during storage time, at end of day 35 MCP-1 level increased to 49.83 ng/L. It is concluded that along with the prolongation of storage time, the growth factors in the supernatant of PRBC display the tendency of accumulative increment and RANTES/CCL5 and TNF-α show relative high level at day 0 of storage, moreover, no obvious increase of accumulation is observed along with prolonging of the storage time, suggesting no relation of concentration with storage time.

OBJECTIVE: To investigate the change of serum MCP-1 level and CCR2 expression in isolated monocytes in patients with acute coronary syndrome (ACS) and its possible relationship with ACS pathogenesis. METHODS: Thirty ACS patients and 30 healthy controls were enrolled. Serum MCP-1 levels were determined by ELISA in all subjects. The protein expression of CCR2 in isolated monocytes was assessed by flow cytometry. RESULTS: Serum MCP-1 concentrations in ACS patients were higher than those in healthy controls (P<0.05) and the ratio of CCR2 protein expression in monocytes in ACS patients was higher than that in healthy controls (P<0.01). CONCLUSION The serum MCP-1 concentrations and protein expression of CCR2 in ACS patients are significantly higher than those in healthy controls, which might be associated with the pathogenesis of ACS.

BACKGROUND: Monocyte chemoattractant protein-1 (MCP-1) belongs to C-C subfamily of chemokines, which stimulates the migration of monocytes. MCP-1 exerts various effects on the monocytes, including the induction of integrin and tissue factor, and synthesis of proinflammatory cytokines and arachidonic acid. In this study, we measured the MCP-1 levels in patients with Behcet's disease and evaluated the associations between the levels of MCP-1 and the level of other chemokines and various clinical features of Behcet's disease. METHODS: Serum samples were obtained from 67 patients with Behcet's disease and 30 healthy controls. Simultaneously, whole blood was isolated from patients (n=25) with Behcet's disease and healthy controls (n=11) and cultured in 24 well plates for 48 hours in the absence or presence of lipopolysaccharide (LPS) 5 microgram/mL, phytohaemagglutinin (PHA) 5 microgram/mL, phorbol 12-myristate 13-acetate (PMA) 50 ng/mL + ionomycin 5 microgram/mL. The MCP-1 concentrations were measured in the sera and culture supernatants by enzyme-linked immunosorbent assay (ELISA). RESULTS: The levels of serum MCP-1 were 2.5 times higher in patients with Behcet's disease than healthy controls. The patients with Behcet's disease had also higher levels of MCP-1 in the culture supernatants of whole blood cells, stimulated with LPS, but not with either PHA or PMA plus ionomycin, compared to healthy controls. Serum MCP-1 levels (n=67) were strongly correlated with serum RANTES, MIP-1alpha, IL-8 levels in Behcet's disease. In addition, the production of MCP-1 by whole blood culture from Behcet's disease patients (n=25) were also correlated well with those of RANTES, MIP-1alpha, and IL-8, when stimulated with LPS. However, MCP-1 levels in the sera and culture supernatants did not show any association with various clinical features of Behcet's disease including oral ulcer, genital ulcer, erythema nodosum, arthritis, uveitis, intestinal involvement, central nervous system involvement, and vascular thrombosis. CONCLUSION: In the sera and culture supernatants of whole blood stimulated with LPS, MCP-1 levels were higher in patients with Behcet's disease than controls and correlated well with RANTES, MIP-1alpha, IL-8 levels. These results suggest that the activation and migration of monocytes triggered by the increased production of MCP-1 may play a role in the pathogenesis of Behcet's disease.

OBJECTIVE: To explore the microvessel counts and the expressions of interleukin-8 (IL-8), monocyte chemoattractant protein-1 (MCP-1), and macrophage inflammatory protein-1 ( MIP-1) alpha mRNA in the pathological scar tissues. METHODS: Immunohistochemical method of avidin-biotin complex was used for microvessel counts on the routinely formalin-fixed and paraffin-embedded sections of specimens of hypertrophic scars, keloids, normal skin, and surgical scar, and in situ hybridization for the expressions of IL-8, MCP-1, MIP-1alpha mRNA. RESULTS: The microvessel counts as well as the positive rates and the scorings of IL-8, MCP-1, and MIP-1alpha mRNA were significantly higher in pathological scars than those in the normal skin and surgical scar (all P < 0.05). The microvessel counts were significantly higher in the positive cases of IL-8, MCP-1 and MIP-1alpha mRNA than those in the negative ones (P < 0.05). The close positive correlations were found among the microvessel counts and the expressive scorings of 3 factors (P < 0.05). The close positive correlations were also found among the expressive scorings of IL-8, MCP-1, and MIP-1alpha mRNA in pathological scars. Microvessel counts were significantly higher in hypertrophic scars with the course less than 1 year than those with the course more than 1 year. CONCLUSION IL-8, MCP-1 and MIP-1alpha play important roles in promoting the neovascularization of pathological scars.

OBJECTIVETo investigate the changes in serum levels of chemokine MCP-1 and MIP-2 after renal transplantation in rats and the influence of Cyclosporin A (CsA) on their levels.

METHODSThree groups of rats, namely untreated group, CsA group and isograft group underwent the renal transplantation, and the serum MCP-1 and MIP-2 levels of the recipients were tested using enzyme-linked immunosorbent assay (ELISA).

RESULTSThe serum MCP-1 level peaked 6 hours after the operation and also in critical stages of acute rejection. The first peak of MCP-1 was postponed by the application of CsA, which did not affect the peak level (P>0.05). The second peak of MCP-1 did not occur in CsA-treated group. MIP-2 concentration also peaked at 6 h after the operation in all the groups. The second peak of MIP-2, which was lower than the first one (P<0.05), occurred 9 days after the transplantation.

CONCLUSIONMCP-1 and MIP-2 in involved not only in the ischemia-reperfusion injury but also in severe acute rejection. CsA has no significant effect on serum levels of MCP-1 and MIP-2 following renal transplantation in rats.

OBJECTIVETo evaluate the effects of Artesunate on tumor necrosis factor alpha (TNF-alpha), monocyte chemoattractant protein (MCP-1), and on reduced activation normal T cell expressed and secreted (RANTES) in the serum and the synoviocyte culture supernate of collagen-induced arthritis (CIA) rats.

METHODSEighty male Wistar rats were selected to establish the CIA rat model. On the 6th day after modeling, 60 rats with the sum of arthritis index of right metapedes and two propodium > or = 6 were selected, and randomly divided into 6 groups (n = 10), i.e., the blank control group, the CIA model control group (treated with normal saline, abbreviated as the CIA group), the MTX positive control group (abbreviated as the MTX group), the large dose Artesunate group (at the daily dose of 20 mg/kg), the moderate dose Artesunate group (at the daily dose of 10 mg/ kg), and the small dose of Artesunate group (at the daily dose of 2.5 mg/kg). Mice were sacrificed 7 days of immune injection and their venous blood was collected to obtain the serum. Meanwhile, the synovial tissues of the knee joint were taken by aseptic techniques and primary cultured for 48 h. The supernate was collected by centrifuge. The changes of MCP-1, RANTES, and TNF-alpha in the serum and the synoviocyte culture supernate were observed in each group before and after treatment using ELISA.

RESULTSArtesunate significantly decreased the expressions of TNF-alpha in the serum and the synoviocyte culture supernate, showing significant difference when compared with the model control groups (P < 0.05). There was no statistical difference in the large dose Artesunate group and the moderate dose Artesunate group when compared with the MTX group (P > 0.05). But statistical difference existed in the large dose Artesunate group, the moderate dose Artesunate group, and the MTX group when compared with the small dose Artesunate group (P < 0.05). Artesunate could significantly decrease the expressions of MCP-1 and RANTES in the serum and the synoviocyte culture supernate, showing statistical difference when compared with the model control group (P < 0.05). But no statistical difference existed when compared with the MTX group (P > 0.05).

CONCLUSIONThe mechanism of anti-inflammatory action and immune regulation of Artesunate might be correlated with the inhibition of inflammatory factor TNF-alpha and chemotactic factors MCP-1 and RANTES.

OBJECTIVETo detect the concentration of monocyte chemoattractant protein-1 (MCP-1) in the serum of patients with incomplete spinal cord injury and evaluate its relation with the pathologic classification of the spinal cord injury.

METHODSMCP-1 concentration in the serum of patients with incomplete spinal cord injury (iSCI), single spine compression and healthy subjects were detected by ELISA, respectively in the present study and the magnetic resonance imaging data of these patients were studied at the same time on a blind base.

RESULTSSerum level of MCP-1 in iSCI patients was 428 pg/ml +/- 11 pg/ml by ELISA, which was higher than both that of the patients with single spine compression and of controls, with the concentration of 184 pg/ml +/- 21 pg/ml and 124 pg/ml +/- 15 pg/ml, respectively. There was significant difference between any two groups (P < 0.01). iSCI patients with normal MRI showed a lower serum level of MCP-1 as 312 pg/ml+/- 30 pg/ml. Pathological classification of spinal cord edema and hematoma corresponded to 390 pg/ml +/- 16 pg/ml and 508 pg/ml+/- 24 pg/ml in the concentration of MCP-1.

CONCLUSIONSMCP-1 may induce secondary inflammatory response by recruiting inflammatory cells to the injury site and thus affect the prognosis of spinal cord injury.

OBJECTIVETo assess the association between peripheral blood dendritic cells subtype distribution and plasma monocyte chemoattractant protein 1 (MCP-1) concentration in patients with coronary heart disease (CHD).

METHODSSixty consecutive CHD patients admitted in our department during the period from November, 2010 to December, 2011 were enrolled, including 10 with stable angina pectoris (SAP), 25 with unstable angina pectoris (UAP), and 25 with acute myocardial infarction (AMI), with 28 healthy volunteers as normal controls. All the subjects underwent routine tests and coronary angiography. The percentages of peripheral blood myeloid dendritic cells (mDCs) and plasma cell-like dendritic cells (pDCs) in peripheral blood mononuclear cells were detected by flow cytometry, and plasma MCP-1 levels were detected using enzyme-linked immunosorbent assay.

RESULTSThe percentage and absolute quantity of mDCs and pDCs were significantly lower in AMI and UAP groups than in the normal control and SAP groups (P<0.001). In the CHD patients, the plasma MCP-1 level was significantly higher than that in the normal control group (P<0.001) with an inverse correlation with the percentage of peripheral mDCs.

CONCLUSIONMCP-1 may promote the migration of mDCs into atherosclerotic plaques and mediate the local immune and inflammatory responses to aggravate plaque instability in CHD patients.
