ABSTRACT
OBJECTIVE: To observe the effect of medicated thread moxibustion of Zhuang Minority medicine on helper T cell 17 (Th17)/ Interleukin-17F(IL-17F) signaling pathway in ulcerative colitis (UC) rats, so as to explore its mechanisms underlying improvement of UC. METHODS: Forty male SD rats were randomly divided into normal control, model, medication and medicated thread moxibustion (MTM) groups, with 10 rats in each group. The UC model was induced by free drinking of 4% dextran sulfate sodium (DSS) for 10 d. After successful modeling, rats of the medication group were treated by gavage of salazosulfapyridine (SASP). Medicated thread moxibustion was applied to unilateral "Tianshu" (ST25) and "Qihai" (CV6) alternatively for rats of the MTM group, once daily for 14 d. The body mass, stool shape, and fecal occult test were recorded and conducted daily to perform disease activity index (DAI) score. H．E. staining was used to display pathological changes of the colon tissue. The Th17 cells and IL-17F and retinoic acid related orphan receptor γ t (ROR-γt) in the colon tissue were detected by flow cytometry, and enzyme-linked immunosorbent assay (ELISA), respectively, and the expression levels of RORγt and IL-17F mRNA in colon tissue were detected by quantitive real-time PCR. RESULTS: After modeling, the DAI score, colonic Th17 percentage, RORγt and IL-17F contents, and RORγt and IL-17F mRNA expression were significantly increased in the model group in contrast to the normal control group (P0.05, except RORγt and IL-17F mRNA expression). H．E. staining showed disappearance of goblet cells, infiltration of a large number of inflammatory cells, exfoliation of the epithelial tissue and edema of colonic mucosal in rats of the model group, which was relatively milder in both medication and MTM groups. CONCLUSION: Medicated thread moxibustion of Zhuang Minority medicine can reduce the inflammatory damage of colon tissue in UC rats, which is associated with its effects in suppressing the expression of RORγt, production of Th17 cells, and secretion of pro-inflammatory factor IL-17F in colon tissue.
ABSTRACT
<p><b>OBJECTIVE</b>To discuss the effect of electroacupuncture at Chengshan (BL 57) on postoperative pain of mixed hemorrhoids.</p><p><b>METHODS</b>One hundred and twenty cases with postoperative pain of mixed hemorrhoids were divided into an electroacupuncture group (60 cases) and a medication group (60 cases) randomly. The disperse-dense wave in frequency of 2Hz/100Hz at Chengshan (BL 57) were used in the electroacupuncture group. Its first treatment was in 30 min after the operation, and then it was given once a day after hip bath in the morning. 2 tablets of Naproxen Sunstained Release Capsule were taken in 30 min after operation in the medication group, and then it was taken 2 tablets a day before dressing change. After 4 times of treatment, evaluate the changing condition of Visual Analogue Scale (VAS) at 5 h, 24 h, 48 h and 72 h after operation.</p><p><b>RESULTS</b>The VAS at 5 h, 24 h, 48 h and 72 h after operation in the electroacupuncture group (6.78 +/- 2.12, 5.56 +/- 1.87, 4.34 +/- 2.23 and 3.15 +/- 2.11) were all lower than those in the medication group (7.56 +/- 2.01, 6.23 +/- 1.15, 5.57 +/- 2.21 and 4.34 +/- 2.12), and the difference was statistically significant (all P < 0.05).</p><p><b>CONCLUSION</b>Electroacupuncture at Chengshan (BL 57) can reduce the postoperative pain of mixed hemorrhoids.</p>
