RESUMO
Objective:To study the effect of modified Erchentang on levels of interleukin-12 (IL-12), interferon-γ (IFN-γ), interleukin-9 (IL-9), interleukin-4 (IL-4) and interleukin-13 (IL-13) in plasma and bronchoalveolar lavage fluid (BALF) of all rats, as well as expressions of interleukin-4 (IL-4) receptor (IL-4R1) and interleukin-13 (IL-13) receptor (IL-13RA1) in bronchioles tissue of rats with chronic obstructive pulmonary disease (COPD). Method:Fifty SD rats were randomly divided into 5 groups, namely normal group, model group, and low, middle and high-dose modified Erchentang groups (5, 10, 20 g·kg-1), with 10 rats in each group. COPD in rat was prepared by using cigarette smoke combined with dripping lipopolysaccharide (LPS) in trachea. After the modeling, normal and model groups were given normal saline solution through intragastric (ig) administration, while other groups were given corresponding herbal drugs (5, 10, 20 g·kg-1) intragastrically (ig) for 14 days. The levels of IL-12, IFN-γ, IL-9, IL-4 and IL-13 in plasma and BALF were detected by Enzyme-linked immunosorbent assay (ELISA) method， and immunohistochemistry (IHC) method was used to detect the expressions of IL-4R1 and IL-13RA1 in bronchioles tissue of all of the groups. Result:Compared with the normal group, the levels of IL-12 and IFN-γ were decreased significantly (P<0.01), but the levels of IL-9, IL-4 and IL-13 in plasma and BALF were significantly increased (P<0.01), and the expressions of IL-4R1 and IL-13RA1 in bronchioles tissue were increased significantly (P<0.01) in model group. Compared with the model group, the levels of IL-12 and IFN-γ were increased significantly, while the levels of IL-9, IL-4 and IL-13 in plasma and BALF were decreased significantly (P<0.01), and the expressions of IL-4R1 and IL-13RA1 in bronchioles tissue were decreased significantly (P<0.01) in modified Erchentang groups (10, 20 g·kg-1). Conclusion:Modified Erchentang has effects in resisting inflammatory and protecting tissue structure of bronchioles. Its mechanism may be correlated with increasing the levels of IL-12, IFN-γ and reducing the levels of IL-9, IL-4 and IL-13 in plasma and BALF, and inhibiting the expressions of IL-4R1 and IL-13RA1 in bronchioles tissue.
RESUMO
Objective: To observe the clinical efficacy of modified Xiaofengsan and its effect on cytokines in persistent asthma patients with wind-asthma pattern. Method: The 120 eligible patients with chronic and persistent asthma were randomly divided into control group (60 cases) and treatment group (60 cases). Patients in control group received the budesonide/formoterol (160 μg/4.5 μg, 2 inhales/time, bid). Patients in treatment group additionally received the modified Xiaofengsan combined with budesonide/formoterol (160 μg/4.5 μg). The treatment course was 1 month in both groups. The clinical efficacy of the two groups was observed. Before and 3 months after treatment, asthma control test (ACT) and the average times of acute exacerbation in 6 months before and after treatment between two groups were observed; percentage of forced expiratory volume in first second and its predicted value (FEV1%), variety ratio of Peak expiratory flow (PEF), eosinophilic granulocyte (EOS) count in peripheral blood and the levels of interleukin-4(IL-4), interleukin-6(IL-6) and interleukin-13(IL-13) in serum were measured before and after treatment respectively. In addition, the safety of the two groups was evaluated. Result: The total effective rate of the treatment group was higher than that of the control group (P1% in treatment group were higher(PPConclusion: Modified Xiaofengsan combined with budesonide/formoterol could relieve symptoms of asthma, improve pulmonary function and lower the levels of IL-4, IL-6 and IL-13 in serum.
RESUMO
Objective The expression of IL-13 in plasma and renal tissue was studied to eluciate the molecular pathogenesis of Mesangial proliferative glomerulonephritis (MsPGN). Methods Plasma level of IL-13 in patients with MsPGN and in normal control groups were examined by ELISA. The expression of IL-13 in patients with MsPGN and in control group were examined by immune histochemistry ABC technique in renal tissue.Results Plasma levels of IL-13 in patients with MsPGN were significantly higher than that in control group,and the highest was found in IgAN;IL-13 expressions in glomerulus and tubulointerstitial zone in patients with MsPGN were higher than that in control group, and IL-13 expression in tubulointerstitial zone was more strong,but it was not distinctive difference between non-IgA MsPGN and IgAN. Conclusion IL-13 may play an important role in the molecular pathogenesis of MsPGN.
RESUMO
Objective To explore the expression of interleukin 13(IL-13) mRNA in peripheral blood mononuclear cells (PBMCs) and its association with serum C-reaction protein(CRP) in patients with ulcerative colitis(UC). Methods IL-13 mRNA expression in PBMCs was detected by RT-PCR in patients with UC(21 cases of active UC and 10 cases of quiescent UC)and 20 healthy subjects. At the same time, the serum level of CRP was detected by ELISA. Results The expression level of IL-13 mRNA in PBMCs of patients with active UC was significantly lower than that in PBMCs of patients with quiescent UC and healthy subjects (6.45?1.23 vs 14.72?2.12 or 15.17?2.38,P0.05). The expression level of IL-13 mRNA in PBMCs of active UC patients was negative correlation with serum level of CRP (r=-0.589,P
