OBJECTIVE@#To observe the effect of electroacupuncture (EA) on expression of interleukin (IL) -23/IL-17 axis and Toll-like receptor 4 (TLR4) in the infarcted tissue in rats with myocardial infarction (MI), and to explore the mechanism of EA on alleviating MI injury.@*METHODS@#Forty male SD rats were randomly divided into a sham-operation group, a sham-operation plus EA group, a model group and an EA group, 10 rats in each group. The MI models were established by ligation of left anterior descending coronary artery in the model group and EA group, while only threading was performed in the sham-operation group and sham-operation plus EA group. The rats in the sham-operation plus EA group and EA group were treated with EA at "Neiguan" (PC 6), disperse-dense wave, 2 Hz/100 Hz, 2 mA, once a day, 20 min each time, for 3 days. After the intervention, the ejection fraction (EF) was measured by echocardiography to evaluate the cardiac function; the infarct area was measured by TTC staining; the HE staining was used to observe the morphological changes of myocardial tissue; the levels of IL-23 and IL-17 in infarcted tissue were detected by ELISA; the protein expression of TLR4 in infarcted tissue was detected by Western blot.@*RESULTS@#Compared with the sham-operation group, the EF was decreased (@*CONCLUSION@#EA may alleviate the excessive inflammatory response after MI by inhibiting the expression of IL-23/IL-17 axis in MI rats, and TLR4 may be involved during the process.

Objective To detect the expression level of interleukin-17 (IL-17)/interleukin-23 (IL-23) axis in peripheral blood of patients with Graves disease (GD) before and after 131I or antithyroid drugs (ATD) treatment.Methods The study groups included 40 patients with incipient GD(GD group),20 of whom were treated by 131 I,others were treated by ATD.Forty sex and age matched healthy subjects were recruited as control group.ELISA was uesed to detect interleukin-17 (IL-17),interleukin-23 (IL-23) level before and after the treatment of the GD group and control group.Results ① The expression of IL-23,IL-17 in GD group was significantly higher than the control group(P <0.05);②6 months after 131I treatment,the level of serum IL-23,IL-17 were significantly lower than before (P < 0.05),but still higher than the control group (P < 0.05),which was not found in ATD treatment group.Conclusion IL-23/IL-17 axis may play a role in GD which may also be relevant to 131I treatment.

Objective:To explore the proportions of Th17 cells in the peripheral blood and levels of IL-17,IL-23 in the serum of patients with Graves′disease ( GD ) and their clinical significance.Methods: We studied 29 patients with GD ( GD group ) , and reevaluated the GD group after therapy ( euthyroid GD group ).29 gender-and age-matched volunteers were selected as the normal control ( NC group).The proportions of Th17 cells were investigated by flow cytometry.The levels of IL-23,IL-17 in the serums were measured by ELISA.The levels of FT3,FT4,TSH were determined by ECLIA and the levels of TrAb were tested by RRA.Results:There were no significant difference among 3 study groups in sex and age match ( F=0.0075 , P>0.05;χ2=0.4213 , P>0.05 ).The proportions of Th17 cells and the levels of IL-17 , IL-23 were increased in the GD and euthyroid GD patients compared with the control group (respectively,P0.05).Correlation analysis revealed that the proportions of Th17 cells ,and the levels of IL-17,IL-23 were positively correlated with the levels of FT3,FT4,TrAb(r=0.588 2,0.337 2,0.371 0;0.549 6,0.287 5,0.342 7;0.361 0,0.420 8, 0.330 8;P<0.05 ,for all parameters ) ,and were negatively correlated with the levels of TSH ( r=-0.319 7 ,-0.472 8 ,-0.428 2;P<0.05,for all parameters).Conclusion:Th17 cells and their related cytokines IL-17,IL-23 are highly expressed in the serum of patients with GD.Th17 cells and their relative cytokines have certain relevance with 4 thyroid function parameters of the patients with GD , which can be used as biological markers for GD.

The treatments for ankylosing spondylitis (AS) are still not effective, which partially due to its unclear patho?genesis. Interleukin (IL)-23/IL-17 axis is a significant immunologic pathway which has attracted much attention in the past few years. This article reviewed the role of IL-23/IL-17 axis in genetic and immunological pathogenesis of AS, and intro?duced the recent progresses in treatments of AS using anti-IL-23 or anti-IL-17 antibody. The important role of IL-23/IL-17 axis in the pathogenesis and treatment of AS indicates its potential use as a new therapeutic target.
