ABSTRACT
This study was aimed to investigate the effect of visceral pain and water metabolism on irritable bowel syndrome with diarrhea (IBS-D) model rats by moxibustion and its products. A total of 40 SD rats were randomly di-vided into the normal group, model group, moxibustion group, non-smoke moxibustion group, and moxa smoke group. IBS-D model was induced by colorectal distension with an inflatable balloon. The general condition of rats was ob-served. Visceral pain was assessed by abdominal withdrawal reflex (AWR) scores. The immunohistochemical method was used in the detection of claudin-1, AQP3, AQP8 and Na+/K+-ATPase protein expression. The results showed that compared with the normal group, the AWR scores, claudin-1, AQP3, AQP8 and Na+/K+-ATPase protein expres-sion in the colon were decreased in the model group (P < 0.01). The stool was loose, which was on hair around the anus. After moxibustion, non-smoke moxibustion and moxa smoke stimulation, the stool conditions of IBS-D model rats were improved. The AWR scores were decreased in different degrees (P < 0.05 or P < 0.01). Except Na+/K+-ATPase, expressions of claudin-1, AQP3 and AQP8 in colon were increased in different degrees (P < 0.05 or P <0.01). The comprehensive therapeutic effect showed that moxibustion was better than non-smoke moxibustion; and non-smoke moxibustion was better than moxa smoke stimulation. It was concluded that the combination of warm stimulation, optical radiation and moxa smoke induced best effect in improving visceral pain and water metabolism on IBS-D model rats. Among them, warm stimulation and optical radiation may play the main role.
ABSTRACT
ObjectiveTo estimate the clinical efficacy and immunomodulatory effect of polysaccharidenucleic acid fraction of bacillus calmette guerin(BCG-PSN) combined with a traditional Chinese medicine in patients with vitiligo.MethodsThis study recruited 99 patients with vitiligo aged from 13 to 65(35,6 ± 5.8) years.The patients were classified into 3 groups to be treated with BCG-PSN and a traditional Chinese medicine (Baidianfeng granules) alone or in combination.BCG-PSN was intramuscularly injected at a dose of 2 ml every other day and baidianfeng granules were given orally thrice a day,for 3 months.Peripheral blood samples were obtained from the patients at the baseline and after the end of treatment and from 30 healthy controls.Flow cytometry and enzyme linked immunosorbent assay(ELISA) were performed to detect T cell subsets and expression level of Fas and Fas ligand(FasL),respectively.Data were analyzed by t test and chi-square test.Results The response rate was significantly higher in patients treated with BCG-PSN combined with Baidianfeng granules than in those with BCG-PSN alone(82.86％ vs.40.63％,P ＜ 0.01 ).Before the treatment,patients showed a lower percentage of CD3+ cells,CD3+CD4+ cells and CD3+CD8+ cells in peripheral blood(all P ＜0.01 ),weaker expression of Fas (P ＜ 0.01 ),but a higher CD4/CD8 ratio (P ＜ 0.01 ) compared with the controls.The treatment with BCG-PSN and Baidianfeng granules alone or in combinatiou all induced an increase in the percentage of CD3+ cells,CD3+CD4+ cells and CD3+CD8+ cells in peripheral blood(P ＜ 0.05) and in the expression of Fas(P ＜ 0.01),but a decrease in CD4/CD8 ratio(P ＜ 0.05).ConclusionsBCG-PSN may induce the normal apoptosis in lymphocytes via reversing the abnormality in the expression of Fas/FasL by peripheral blood lymphocytes,and the effect of BCG-PSN may be enhanced by a traditional Chinese medicine,Baidianfeng granules.
ABSTRACT
Objective:To observe the hemorheological change of vitiligo patients both before and after treatment by Vitiligo Granules or Vitiligo Liniment combined with UVA phototherapy, researching the relationship and clinical significance between vitiligo and hemorheology. Methods: Hemorheological detection was made before and after treatment for 30 normal cases and 58 cases of vitiligo. Results: The total effective rate was 74.15%. The indexes levels of hemorheology of treatment group was higher than those of normal group before treatment (P
ABSTRACT
Objective To investigate the role of Fas antigen,Fas ligand(FasL)and soluble Fas(sFas)in the pathogenesis of vitiligo.Methods The expression of Fas and FasL on peripheral blood lym-phocyte(PBLC)was detected by flow cytometry.Serum sFas was quantitated using a dual antibody sandwich enzyme-linked immunosorbant assay(ELISA).Results The expression of Fas and FasL was significantly de-creased in patients with vitiligo vulgaris(43.45%and58.40%)than those in normal controls(58.30%and64.65%)(P
