Enzyme-linked immunosorbent assay (ELISA) double antibody sandwich method was used to detect the changes of serum TNF-α, IL-2 and IL-13 in the observation group before and after treatment, and was correlated with rheumatoid arthritis disease activity index, plasma ESR, CRP level and DAS28 score.Results:before treatment, serum TNF-α, IL-2 alpha and IL-13 were significantly higher than those in the control group, the observation group of serum TNF-α, IL-2 and IL-13 levels were significantly lower than those before treatment, and compared with the control group, the difference was not statistically significant. Before treatment, the changes of serum TNF-α alpha, IL-2 and IL-13 during the onset of rheumatoid arthritis were positively correlated with the level of plasma ESR, CRP and DAS28.Conclusions:the serum levels of TNF-α, IL-2 and IL-13 in rheumatoid arthritis patients are significantly increased, and are closely related to the activity of rheumatoid arthritis. Patients can be effectively improved after treatment, which is worthy of clinical reference.展开更多
目的观察IL-13对9HTE气道上皮细胞内Egr-1、Bax、Bcl-2 m RNA和蛋白表达的影响,探讨IL-13在气道上皮细胞凋亡中的作用及机制。方法将9HTE气道上皮细胞分为正常对照组、rh IL-13组及rh IL-13+m AIL-13组,用逆转录-多聚酶链反应(RT-PCR)...目的观察IL-13对9HTE气道上皮细胞内Egr-1、Bax、Bcl-2 m RNA和蛋白表达的影响,探讨IL-13在气道上皮细胞凋亡中的作用及机制。方法将9HTE气道上皮细胞分为正常对照组、rh IL-13组及rh IL-13+m AIL-13组,用逆转录-多聚酶链反应(RT-PCR)法检测Egr-1、Bax、Bcl-2 m RNA表达水平,用免疫细胞化学(ICC)法检测Egr-1、Bax、Bcl-2蛋白表达水平。结果rh IL-13组Egr-1、Bax m RNA及蛋白表达显著高于正常对照组(P<0.01),Bcl-2 m RNA及蛋白表达显著低于正常对照组(P<0.01);rh IL-13+m AIL-13组Egr-1、Bax m RNA及蛋白表达显著低于rh IL-13组(P<0.01),与正常对照组比较无显著性差异(P>0.05),Bcl-2 m RNA及蛋白表达显著高于rh IL-13组(P<0.01),与正常对照组比较无显著性差异(P>0.05)。结论 IL-13可能通过Egr-1促进9HTE气道上皮细胞凋亡;m AIL-13可以中和IL-13所致的9HTE气道上皮细胞凋亡的作用。展开更多
