Effects of moxibustion on serum IL-6, IL-8 and TNF-α in rats with experimental rheumatoid arthritis / 针灸推拿医学（英文版）

Objective:To observe the effects of moxibustion on serum levels of interleukin (IL)-6, IL-8 and tumor necrosis factor-α (TNF-α), and to explore the effects of moxibustion on inflammatory damaging factors in experimental rheumatoid arthritis (RA) model rats; the relationship between the therapeutic effect of moxibustion on RA and the change in the Toll-like receptor (TLR) signaling pathway was analyzed using Toll-like receptor 4 (TLR4) antagonists and agonists. Methods:Fifty Sprague-Dawley (SD) rats were divided into a normal group, a model group, a moxibustion group, a moxibustion plus TLR4 agonist group (agonist group) and a moxibustion plus TLR4 antagonist group (antagonist group) according to the random number table, with 10 rats in each group. Except the normal group, rats in the other four groups were subjected to model preparation with the wind, cold and wet environmental factors plus Freund's complete adjuvant (FCA). Rats in the normal and model groups were not treated; rats in the moxibustion, agonist and antagonist groups started to be treated with the moxibustion (cigarette-type moxa) at bilateral Shenshu (BL 23) and Zusanli (ST 36) from the 4th day after the successful modeling, for 20 min each time with a total of 10 d. Rats in the agonist and the antagonist groups were injected with TLR4 agonist or antagonist [0.1 mg/(kg·bw)] via the tail vein 30 min before moxibustion. The concentrations of serum IL-6, IL-8 and TNF-α in each group were determined by enzyme-linked immunosorbent assay (ELISA). Results:Compared with the normal group, in the model group, the rat's right hind paw swelling was significantly obvious (P<0.01), there was a lot of inflammatory infiltration in the synovial tissues, the surface of the synovial membrane was unsmooth, the synovial membrane was hyperplasia and thicker, and the serum IL-6, IL-8 and TNF-α concentrations increased significantly (P<0.05). Compared with the model group, the paw swelling degrees of the rats in the moxibustion, the agonist and the antagonist groups reduced significantly (allP<0.01); the swelling degree in the antagonist group was milder than that in the agonist group, but the between-group difference was not statistically significant (P>0.05); inflammatory infiltration and synovial membrane hyperplasia in the synovial tissues of the moxibustion group and the antagonist group were all relieved differently; the decrease of synovial layer number in the moxibustion group was more obvious, and there were no obvious improvements in inflammatory infiltration and synovial thickness in the agonist group; the concentrations of IL-6, IL-8 and TNF-α in the moxibustion group were decreased, and the differences in the IL-6 and TNF-α concentrations were statistically significant (allP<0.01); there was no significant between-group difference in the IL-8 concentration (P>0.05); the concentrations of serum IL-8 and TNF-α in the agonist group increased significantly (both P<0.01), while the IL-6 concentration decreased without significant difference (P>0.05); the concentrations of IL-6 and IL-8 in the antagonist group decreased but the between-group differences were statistically insignificant (bothP>0.05), and the TNF-α concentration significantly increased (P<0.05). Compared with the moxibustion group, IL-6, IL-8 and TNF-α concentrations increased in the agonist group, and the differences in the IL-8 and TNF-α concentrations were statistically significant (both P<0.01); the concentrations of IL-6, IL-8 and TNF-α increased in the antagonist group, and the differences in the IL-6 and TNF-α concentrations were statistically significant (bothP<0.01); there was no significant difference in the IL-8 concentration between the groups (P>0.05). The serum levels of IL-6, IL-8 and TNF-α in the antagonist group were lower than those in the agonist group (allP<0.05). Conclusion:Moxibustion at Shenshu (BL 23) and Zusanli (ST 36) can reduce the joint swelling degree and inflammation in synovial tissue of RA model rats, decrease the serum levels of IL-6, IL-8 and TNF-α in RA model rats; the decreases of IL-6 and TNF-α are more significant than the decrease of IL-8; TLR4 agonist and antagonist can significantly attenuate the effect of moxibustion in inhibiting releases of IL-6, IL-8 and TNF-α, so that the change in TLR signaling pathway affects the effect of moxibustion in inhibiting the releases of IL-6, IL-8 and TNF-α.

Effects of electroacupuncture on the expression of oxidized low-density lipoprotein and its receptors in rats with coronary atherosclerotic heart disease / 中国针灸

<p><b>OBJECTIVE</b>To explore action mechanism of electroacupuncture for coronary atherosclerotic heart disease (CHD) in order to provide experimental support for clinical acupoint selection.</p><p><b>METHODS</b>Among sixty clean-grade healthy male Wistar rats, twenty-four cases were randomly selected as a normal control group and an electroacupuncture (EA) preconditioning group, 12 cases in each one. Then rats in the EA preconditioning group and the rest 36 rats were fed with high fat diet for 12 weeks to duplicate the CHD model. When the models were successfully established, the rats were randomly divided into a model control group, an EA group and a medication group, 12 cases in each one. EA was applied with Hwa-to SDZ-IV apparatus in the EA preconditioning group at "Neiguan" (PC 6) and "Xinshu" (BL 15), 1 mA in current intensity, 2 Hz in frequency, 30 min per times, once every other day for 14 weeks. When model was established, the same acupoint and method was used in the EA group for 2 weeks while intragastric administration of atorvastatin mixed suspension, 0.25 mg/kg, once a day, was applied in the medication group for 2 weeks. The content of oxidized low-density lipoprotein (oxLDL) in the serum was tested by double antibody enzyme-linked immunosorbent assay (ELISA) while content of lectin-like oxidized low density lipoprotein receptor-1 (LOX-1) in coronary arterial tissue was test by western blot method. Expression of LOX-1 mRNA was tested by fluorogenic quantitative polymerase chain reaction (PCR).</p><p><b>RESULTS</b>After model was duplicated successfully, the content of oxLDL in the serum and the expression of LOX-1 and its mRNA in coronary arterial tissue in the model control group were increased significantly compared with those in the normal control group (all P < 0.01). Compared with the model control group, the content of oxLDL in the serum and the expression of LOX-1 and its mRNA in coronary arterial tissue in the EA preconditioning group, EA group and medication group were significantly reduced (all P < 0.01).</p><p><b>CONCLUSION</b>The electroacupuncture at "Neiguan" (PC 6) and "Xinshu" (BL 15) could effectively reduce the content of oxLDL in the serum and expression of LOX-1 and its mRAN in coronary arterial tissue in CHD rats. The oxidative modificatory low-density lipoprotein and its specific receptor system could be one of the ways to prevention and treatment of acupuncture for CHD.</p>
