The effects of Wumeiwan （WMW） on TNF-α, IL-6, IL-8, IL-10 and NF-κBp65 in rats with ulcerative colitis （UC） were investigated, the curative effectiveness of WMW vs salicylazosulfapyridine （SASP） was compared, ...The effects of Wumeiwan （WMW） on TNF-α, IL-6, IL-8, IL-10 and NF-κBp65 in rats with ulcerative colitis （UC） were investigated, the curative effectiveness of WMW vs salicylazosulfapyridine （SASP） was compared, and the action mechanism was analyzed. Fifty-Six Sprague-Dawley （SD） rats were randomly divided into four groups （n=14 in each group, with equal ratio of male and female）： normal control group, model group, SASP group, and WMW group. Except normal control group, the rat UC models in the remaining three groups were established using the method of 2.4-dinitrochlorobenzene （DNCB） immunization and acetic acid local enema. The rats in model group, SASP group, and WMW group were treated with distilled water, SASP, and WMW respectively. The changes in the symptoms and signs were observed, and levels of IL-6, IL-8, TNF-α, IL-10 and the expression of NF-κBp65 in the colonic tissues were statistically analyzed. The results showed that the levels of IL-6, IL-8, and TNF-α were significantly increased （P〈0.01）, while those of IL-10 significantly reduced （P〈0.01） after establishment of rat UC models as compared with normal control group. The levels of IL-6, IL-8, and TNF-α were obviously lower, but the level of IL-10 was obviously higher in WMW and SASP groups than those in model group （P〈0.05）. The levels of IL-6, IL-8, and TNF-α were lower, while the level oflL-10 was higher in WMW group than in SASP group. NF-κBp65 was expressed negatively or weakly in normal colonic tissues. The positive expression rate of NF-κBp65 in WMW group and SASP group was obviously lower than in model group （P〈0.01）, and there was significant difference between WMW group and SASP group （P〈0.05）. It was concluded that rat UC model was established successfully. WMW could up-regulate the expression of IL-10, down-regulate the expression of TNF-α, IL-6, IL-8, and inhibit the NF-κBp65 activity to adjust immune function, indicating WMW had better curative effects on UC in rats.展开更多

Ninety-eight SD rats were randomly divided into seven groups, namely, the normal control group, model group, salicylazosulfapyridine (SASP) group,Wumeiwan (WMW) group, Baitouwengtang (BTWT) group,Senglingbaishusan (SLBSS) group, and Tongxieyaofang (TXYF) group. Each group had 14 rats (with equal ratio of male and female). The six animal model groups of UC-SASP, TXYF, WMW, BTWT, SLBSS, TXYF-were treated by distilled water except the normal control group. Changes of the rat's general conditions after treatment were respectively observed, the colon tissue damage scores were given out, the pathology of colonic mucosa and changes of ultrastructure were analyzed.RESULTS: Different pathological changes on histology were shown after treatment by FRIP. The colon tissue damage score in model group was higher than that of FRIP groups and SASP group (q = 4.59, 4.77, P＜0.05 or q = 5.48,6.25, 5.97, P＜0.01). The scores of WMW group, BTWT group and SLBSS group were lower than that of SASP (q = 4.13, P＜0.05 or q = 5.31, 5.12, P＜0.01). There was no remarkable difference between the damage score of TXYF group and SASP group (q = 3.75, P＞0.05). In addition, some apoptosis cells were found in the pathologic control group.CONCLUSION: The model made with DNCB and acetic acid was successful, and FRIP had better curative effect and WMW was the best curative effect, BTW, SLBSS and TXYF were similar to SASP, and we discovered that apoptosis was possibly related to UC.展开更多

We aimed to study the eradication rates of different regimens in our region and some factors affecting the rate of eradication. METHODS:One hundred and sixty-four H pylori positive patients (68 males,96 females;mean age:48±12 years) with duodenal or gastric ulcer without a smoking history were included in the study.The patients were divided into three groups according to the treatment regimens.Omeprazole 20mg,clarithromycin 500mg,amoxicillin 1g were given twice daily for 1 week (Group Ⅰ) and 2 weeks (Group Ⅱ). Patients in Group Ⅲ received bismuth subsitrate 300mg, tetracyline 500mg and metronidazole 500mg four times daily in addition to Omeprazole 20mg twice daily.Two biopsies each before and after treatment were obtained from antrum and corpus,and histopathologically evaluated. Eradication was assumed to be successful if no H pylorus was detected from four biopsy specimens taken after treatment.The effects of factors like age,sex,H pylori density on antrum and corpus before treatment,the total H pylori density,and the inflammation scores on the rate of H pylori eradication were evaluated. RESULTS:The overall eradication rate was 42%.The rates in groups Ⅱ and Ⅲ were statistically higher than that in group Ⅰ (P<0.05).The rates of eradication were 24.5%, 40.7% and 61.5% in groups Ⅰ,Ⅱ and Ⅲ,respectively.The eradication rate was negatively related to either corpus H pylori density or total H pylori density (P<0.05).The median age was older in the group in which the eradication failed in comparison to that with successful eradication (55 yr vs 39 yr,P<0.001).No correlation between sex and H pylori eradication was found. CONCLUSION:Our rates of eradication were significantly lower when compared to those reported in literature.We believe that advanced age and high H pylori density are negative predictive factors for the rate of H pylori eradication.展开更多

METHODS: Sixty-seven patients with GPL confirmed by gastroscopy and pathology were studied,including 39 cases of moderate gastric mucosal dysplasia,19 cases of severe gastric mucosa dysplasia, 9 cases of incomplete colon metaplasia. In syndrome differentiation of TCM,17 cases belonged to the syndrome of qi and yin deficiency of the spleen and stomach complicated by qi stagnation, 21 cases belonged to the syndrome of qi and yin deficiency of the spleen and stomach complicated by stomach heat, 29 cases belonged to the syndrome of qi and yin deficiency of the spleen and stomach complicated by blood stasis. Protein and mRNA expression of bcl-2 oncogene were detected by labeled streptavidin biotin (LSAB) immunohist-ochemistry and in situ hybridization respectively. RESULTS: Abnormal expression of protein and mRNA on bcl-2 oncogene was found in GPL,which increased gradually with the course of lesions. In moderate and severe gastric mucosal dysplasia and incomplete colon metaplasia,there was no difference in the expression of bcl-2 oncogene (P>0.05).In different accompanying syndromes, the expression of protein and mRNA on bcl-2 oncogene increased gradually in the following order: deficiency of both qi and yin of the spleen and stomach accompanying qi stagnation→stomach heat→blood stasis. In GPL, compared with accompanying blood stasis, there was an obvious difference in the expression of bcl-2 oncogene between the syndrome of qi and yin deficiency of the spleen and stomach and accompanying stomach heat, so did accompanying qi stagnation (the level of protein: X2=8.45, P<0.05;the level of mRNA: X2=7.35, P<0.05). CONCLUSION: Apoptosis-associated bcl-2 oncogene is abnormally expressed in GPL,which correlates with different accompanying syndromes in TCM.展开更多

文摘AIM: To observe the protein and mRNA expression of bcl-2 oncogene in gastric precancerous lesions (GPL) and to analyze its correlation with syndromes in traditional Chinese medicine (TCM). METHODS: Sixty-seven patients with GPL confirmed by gastroscopy and pathology were studied,including 39 cases of moderate gastric mucosal dysplasia,19 cases of severe gastric mucosa dysplasia, 9 cases of incomplete colon metaplasia. In syndrome differentiation of TCM,17 cases belonged to the syndrome of qi and yin deficiency of the spleen and stomach complicated by qi stagnation, 21 cases belonged to the syndrome of qi and yin deficiency of the spleen and stomach complicated by stomach heat, 29 cases belonged to the syndrome of qi and yin deficiency of the spleen and stomach complicated by blood stasis. Protein and mRNA expression of bcl-2 oncogene were detected by labeled streptavidin biotin (LSAB) immunohist-ochemistry and in situ hybridization respectively. RESULTS: Abnormal expression of protein and mRNA on bcl-2 oncogene was found in GPL,which increased gradually with the course of lesions. In moderate and severe gastric mucosal dysplasia and incomplete colon metaplasia,there was no difference in the expression of bcl-2 oncogene (P>0.05).In different accompanying syndromes, the expression of protein and mRNA on bcl-2 oncogene increased gradually in the following order: deficiency of both qi and yin of the spleen and stomach accompanying qi stagnation→stomach heat→blood stasis. In GPL, compared with accompanying blood stasis, there was an obvious difference in the expression of bcl-2 oncogene between the syndrome of qi and yin deficiency of the spleen and stomach and accompanying stomach heat, so did accompanying qi stagnation (the level of protein: X2=8.45, P<0.05;the level of mRNA: X2=7.35, P<0.05). CONCLUSION: Apoptosis-associated bcl-2 oncogene is abnormally expressed in GPL,which correlates with different accompanying syndromes in TCM.
