OBJECTIVETo explore the effect of nuclear factor-kappa B (NF-κB) decoy oligodeoxynucleotides (ODN) on serum NF-κB, IL-10, IL-13 and pulmonary NF-κB protein expression in rabbits with severe lung contusion.
METHODSForty New Zealand rabbits were randomly divided into severe lung contusion group (group A, n=12), lung contusion with NF-κB scrambled decoy ODN group (group B, n=12), lung contusion with sense NF-κB decoy ODN group (group C, n=12), and normal control group (n=4). After establishment of the contusion injury model, the sense and scrambled NF-κB decoy ODN were infused into the rabbits via the jugular vein accordingly. Serum NF-κB, IL-10, and IL-13 and NF-κB protein expressions in the lung tissue were detected before and at 1, 2, 3, and 4 h after the contusion.
RESULTSTwo hours after sense NF-κB decoy ODN intervention, the expression of NF-κB began to decrease and reached the lowest level at 3 h; pulmonary IL-10 and IL-13 expressions decreased at 1 h after contusion, to the lowest level at 2 and 4 h, respectively. After sense NF-κB decoy ODN intervention, the expression of IL-10 and IL-13 increased and NF-κB protein expression decreased significantly in comparison with those in groups A and B (P<0.01).
CONCLUSIONSense NF-κB decoy ODN can significantly reduce the serum NF-κB expression, increase serum IL-10 and IL-13 levels and decrease pulmonary NF-κB protein expression in the early stages after severe lung contusion in rabbits.

4.Determination of serum interleukin-13 and nerve growth factor in patients with systemic lupus erythematosus and clinical significance.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2005;25(3):360-1
The changes in the levels of serum interleukin-13 (IL-13) and nerve growth factor (NGF) in patients with systemic lupus erythematosus (SLE) and their clinical significance were investigated. Sandwich ELISA was used to determine the levels of serum IL-13 and NGF in 35 SLE patients and 15 normal controls. The results showed that the levels of serum IL-13 (92.69+/-9.87 pg/ml) and NGF (339.69+/-25.60 pg/ml) in active SLE patients were significantly higher than those in inactive SLE patients (IL-13, 54.22+/-9.31 pg/ml; NGF, 300.89+/-33.51 pg/ml) (P<0.01). The inactive patients also had significantly increased serum levels of IL-13 and NGF as compared with normal controls (IL-13, 35.20+/-12.70 pg/ml; NGF, 111.40+/-32.54 pg/ml; P<0.05 and P<0.01, respectively). Spearman correlation analysis revealed that the serum IL-13 levels were correlated with disease activity index of SLE (SLEDAI), ESR and serum levels of C3 (r= 0. 813, 0.504, -0.605, respectively). The serum NGF levels were also correlated with above markers (r=0.442, 0.338, -0.463, respectively). The serum levels of IL-13 and NGF had a positive correlation (r=0.506, P<0.01). It was suggested that IL-13 and NGF might be involved in the pathogenesis of SLE and closely correlated with disease activity.

OBJECTIVE:
To study the role of serum IL-10, 12, 13, 16 in patients with allergic rhinitis and vasomotor rhinitis.
METHOD:
The serum levels of IL-10, 12, 13, 16 were measured by ELISA in 30 cases of allergic rhinitis, 25 cases of vasomotor rhinitis and 20 healthy people.
RESULT:
The level of IL-12 in allergic rhinitis was (170.33 +/- 90.58) ng/L, which was significantly lower than that of normal controls [(376.69 +/- 140.70) ng/L, P < 0.01]. The levels of IL-13 and IL-16 in allergic rhinitis were (408.51 +/- 189.68) ng/L and (151.53 +/- 63.56) ng/L, which were significantly higher than those of normal controls [(151.92 +/- 85.08) ng/L, (60.65 +/- 32.45) ng/L, P < 0.01]. There were no significant difference of levels of IL-10, 13, 16 between vasomotor rhinitis and normal controls, while the level of IL-12 in vasomotor rhinitis was lower than that of normal controls [(196.03 +/- 96.31) ng/L vs. (376.69 +/- 140.70) ng/L, P < 0.01]. It was suggested that IL-10 had positive correlation with IL-12 (r = 0.73, P < 0.01), and IL-13 had positive correlation with IL-16 (r = 0.94, P < 0.01).
CONCLUSION
The imbalance of IL-12, IL-13 and IL-16 play crucial roles of regulation in the onset and developing of allergic rhinitis. Further research is needed on the role of IL-12 in vasomotor rhinitis.

Chinese Journal of Integrated Traditional and Western Medicine 2010;30(2):208-210
OBJECTIVETo study the influence of modified Shegan Mahuang Decoction (SGMH) on cytokines such as tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-10 and IL-13 in children suffered from cough and variant asthma (C&VA).
METHODSOne hundred and fifty-four children with C&VA were randomly assigned to two groups: 79 in the treatment group were medicated orally with SGMH one dose per day taking in twice; 75 in the control group were medicated with Montelukast once a day in dose of 4 mg for children aged from 2 to 5 years and 5 mg for those from 6 to 14 years, the medication for all was given 4 weeks. Serum contents of cytokines, including TNF-alpha, IL-10 and IL-13, in patients were measured before and after treatment. Besides, serum contents of these cytokines in 45 healthy children were measured for control.
RESULTSSerum levels of TNF-alpha and IL-3 in the treatment group were 2510 +/- 1500 ng/L and 60.76 +/- 23.67 ng/L, and in the control group, 2890 +/- 1410 ng/L and 61.56 +/- 20.37 ng/L, respectively, all were significantly higher than those of healthy (709 +/- 280 ng/L and 39.49 +/- 3.09 ng/L, P < 0.01); but level of IL-10 was significant lower in the two patient groups than that in control (1546 +/- 1434 ng/L and 1823 +/- 1314 ng/L vs 7123 +/- q2641 ng/L, P < 0.01). After treatment, the levels of TNF-alpha and IL-13 decreased and IL-10 increased significantly in the treatment group, and showed significant different to those in the control group respectively (960 +/- 420 ng/L, 43.67 +/- 12.37 ng/L and 6834 +/- 2216 ng/L vs 2610 +/- 1220 ng/L, 50.56 +/-19.56 ng/L and 2529 +/- 1223 ng/L, P < 0.01). Clinical efficacy between groups also showed that the total effective rate in the treatment group was significantly better (86.07% vs. 42.67%, P < 0.01).
CONCLUSIONSGMH can regulate the serum levels of TNF-alpha, IL-10 and IL-13, and shows evident clinical effect in treating children's C&VA.

OBJECTIVETo investigate the effects of polyinosinic-polycytidylic acid (polyI:C) on the production of thymic stromal lymphopoietin (TSLP) and airway inflammation in mice with exacerbated asthma induced by respiratory syncytial virus (RSV).
METHODSThirty-two female BALB/c mice were randomly divided into 4 groups, namely the PBS control group, OVA group, OVA/RSV group, and OVA/RSV/polyI:C group. In the latter 3 groups, the mice were sensitized by OVA and stimulated with nebulized OVA. RSV was inoculated into the nasal cavity of the sensitized mice and polyI:C (1 mg/kg) was intramuscularly administered. The airway response to metacholine was examined, and the serum levels of IL-4, IL-5, IL-13, and IFN-γ and TSLP in the supernatants of bronchoalveolar lavage fluid (BALF) were detected using ELISA. The total BALF cells, eosinophils, lymphocytes and neutrophils were counted. The lung specimens were collected to observe the inflammation with HE staining, and immunohistochemistry was employed to determine TSLP production in the airway epithelial cells.
RESULTSThe mice in RSV/OVA/polyI:C group showed a significantly lower airway responsiveness to metacholine than those in OVA/RSV group (P<0.01). Compared with OVA/RSV group, RSV/OVA/polyI:C group showed significantly lower serum levels of IL-4, IL-5, IL-13 and TSLP in BALF (P<0.05), with also lower total BALF cells, eosinophils and lymphocytes (P<0.05) and lessened infiltration of the airway inflammatory cells. Immunohistochemistry of TSLP also demonstrated a lower production of TSLP in the airway epithelial cells in RSV/OVA/polyI:C group than in OVA/RSV group.
CONCLUSIONSpolyI:C can inhibit the increase in TSLP production in the airway epithelial cells after RSV infection and relieve airway inflammation in mice with RSV-induced asthma exacerbation.

OBJECTIVETo explore the relationship between IL-3 gene polymorphism and the levels of serum IL-3 and eosinophil cation protein (ECP) for understanding the role of IL-3 gene polymorphism in the mechanism of childhood asthma.
METHODSThe method of restriction fragment length polymorphism (RFLP) was adopted in detecting +1923 site polymorphism of IL-13 gene in intron 3 region, ELISA was employed in detecting the level of serum IL-13, and fluorescent enzyme-linked immunoassay was used to detect the level of serum ECP.
RESULTSThe frequency distribution of TT, TC genotypes of IL-13 Intron 3+1923 site in asthmatic children was higher than that of CC genotype in normal control (P<0.05), and the levels of serum IL-13 and ECP of TT, TC genotypes were significantly higher than those of CC genotype respectively (P<0.01).
CONCLUSIONThe close relationship of IL-3 gene polymorphism with the levels of serum IL-13 and ECP suggests that IL-3 gene polymorphism may play an important role in the mechanism of childhood asthma.

OBJECTIVETo study the infiltration of macrophages and their phenotype in the healing process of full-thickness wound in rat.
METHODSThirty healthy SD rats were divided into control group (n = 6) and injury group (n = 24) according to the random number table. Two round full-thickness skin defects (11 mm diameter) were created on both sides of dorsal spine of rats in injury group with surgical scissors and homemade trephine. After injury, wound area was measured immediately. The wounds were disinfected with iodophor every day. Rats in control group received anesthesia and hair removal only. On post injury day (PID) 1, 3, 7, and 13, respectively, 6 rats of injury group were sacrificed after the measurement of wound area (wound healing rate was calculated). Wound samples were obtained by excision down to healthy fascia along wound edge. Histological study was done with HE staining. The expression of CD68 (the surface marker of macrophage) in the wound tissue was observed with immunohistochemical staining. The double positive expressions of induced nitric oxide synthase (iNOS) plus CD68 (type I macrophage) and arginase 1 (Arg-1) plus CD68 (type II macrophage) were observed with immunofluorescence staining. The levels of interferon-γ (IFN-γ), TNF-α, IL-4, IL-13, IL-10, and IL-12 in wound tissue were assayed by double-antibody sandwich ELISA, and the ratio of IL-10/IL-12 was calculated. Full-thickness skin tissues (11 mm diameter) in rats of control group were excised at the same site as rats in injury group, and the histological observation and cytokines assay were performed as well. Data were processed with one-way analysis of variance or LSD- t test.
RESULTSWound area of rats in injury group was gradually reduced after injury, and the overall difference of the wound healing rate on each PID was statistically significant (F = 358.55, P < 0.01). No abnormal appearance of skin tissue was observed in rats of control group. In injury group, inflammatory cell infiltration was obvious in wound tissue on PID 1 and 3; vascular structure and fresh collagen were observed in wound tissue on PID 7 and 13. Numbers of CD68 positive cells in skin tissue of rats in control group and wound tissue of rats in injury group on PID 1, 3, 7, and 13 were respectively (2.7 ± 1.5), (31.8 ± 3.5), (40.8 ± 4.7), (20.8 ± 2.8), (3.2 ± 2.4) per 200 times visual field (F = 180.55, P < 0.01). Compared with that in control group, the number of CD68 positive cells of rats in injury group was increased on PID 1, 3, and 7 (with t values respectively 18.81, 18.79, 14.05, P values below 0.01). No double positive expression of iNOS plus CD68 or Arg-1 plus CD68 was observed in normal tissue of rats in control group. In injury group, proportions of iNOS plus CD68 double positive cells on PID 1, 3, 7, and 13 were respectively (12.2 ± 2.8)%, (16.5 ± 2.9)%, (4.2 ± 2.3)%, (0.7 ± 0.8)% (F = 72.50, P < 0.01); proportions of Arg-1 plus CD68 double positive cells on PID 1, 3, 7, and 13 were respectively 0, (8.2 ± 1.9)%, (21.5 ± 3.4)%, (4.7 ± 2.0)% (F = 120.93, P < 0.01). In injury group, proportion of iNOS plus CD68 double positive cells on PID 3 was significantly higher than that on other PID (with t values respectively 2.65, 8.17, 12.95, P values below 0.05); proportion of Arg-1 plus CD68 double positive cells on PID 7 was higher than that on other PID (with t values respectively 15.27, 8.25, 10.38, P values below 0.01). Compared with that of Arg-1 plus CD68 double positive cells, proportion of iNOS plus CD68 double positive cells was higher on PID 1 and 3 (with t values respectively 10.71 and 5.88, P values below 0.01) and lower on PID 7 and 13 (with t values respectively 10.24 and 4.60, P values below 0.01). The overall differences of IFN-γ, TNF-α, IL-4, IL-13, and IL-10/IL-12 ratio in skin tissue of rats in control group and wound tissue of rats in injury group on every PID were statistically significant (with F values from 14.08 to 631.03, P values below 0.01). Compared with those in control group, levels of IFN-γ, TNF-α, IL-4, and IL-13 in wound tissue of rats in injury group were significantly higher on every PID (with t values from 4.58 to 9.17, P values below 0.05), while IL-10/IL-12 ratio was significantly higher on PID 1, 3, and 7 (with t values respectively 27.70, 30.51, 9.49, P values below 0.05) . In injury group, IFN-γ level on PID 1 [(61 ± 5) pg/mL] and IL-10/IL-12 ratio on PID 3 (1.647 ± 0.098) were significantly higher than those of control group and those on other PID in injury group [with IFN-γ level respectively (32 ± 4), (54 ± 6), (46 ± 7), (47 ± 4) pg/mL and IL-10/IL-12 ratio respectively 0.328 ± 0.045, 0.960 ± 0.034, 0.530 ± 0.028, 0.289 ± 0.040, with t values respectively from 3.19 to 8.20 and from 16.59 to 31.84, P values below 0.05].
CONCLUSIONSMacrophage infiltration increases in the healing process of full-thickness wound in rat with different phenotypes, among which type I macrophage appears in the inflammatory stage, and type II macrophage predominates in the proliferative stage.
