枫蓼肠胃康联合5⁃FU抑制IL⁃6/STAT3通路治疗结肠炎相关性结肠癌的实验研究

目的:探讨枫蓼肠胃康联合5⁃氟尿嘧啶给药对结肠炎相关性结肠癌小鼠的治疗作用及机制。方法:建立结肠炎相关性结肠癌小鼠模型,经枫蓼肠胃康和5⁃氟尿嘧啶给药后,观察小鼠的行为及活动情况;HE染色观察小鼠结肠组织的病理学变化;采用Western blot检测小鼠结肠组织在IL⁃6/STAT3通路相关蛋白的表达。结果:联合给药组小鼠的存活率明显提高,且小鼠肠壁增厚及间质炎症情况明显减轻。Western blot结果显示经造模后小鼠结肠组织中P⁃STAT3及IL⁃6的表达水平明显升高,联合给药后,抑制了IL⁃6/STAT3通路中Cyclin D1、CDK4和Bcl⁃2蛋白表达,上调了Bax的表达(P<0.05)。结论:枫蓼肠胃康联合5⁃氟尿嘧啶可抑制IL⁃6/STAT3通路来发挥对结肠炎相关性结肠癌的抑制作用。

Study on the mechanism of action of Feng-Liao-Chang-Wei-Kang combined with 5-fluorouracil in the treatment of colitis-associated colon cancer

Objective:To investigate the therapeutic effects and mechanisms of Feng-Liao-Chang-Wei-Kang combined with 5-fluorouracil administration in mice with colitis-associated colon cancer.Methods:To establish a colitis-associated colon cancer mouse model and observe the behavior and activity of mice after Feng-Liao-Chang-Wei-Kang and 5-fluorouracil administration;HE staining to observe the pathological changes of mouse colonic tissue;Western blot was used to detect the expression of mouse colon tissue in IL-6/STAT3 pathway-related proteins.Results:The survival rate of mice in the co-administered group was significantly increased,and the intestinal wall thickening and interstitial inflammation of mice were significantly reduced.Western blot results showed that the expression levels of P-STAT3 and IL-6 were significantly increased in the colonic tissue of mice after modeling,and the combined administration inhibited the expression of Cyclin D1,CDK4 and Bcl-2 protein in the IL-6/STAT3 pathway and upregulated the expression of Bax(P<0.05).Conclusion:Feng-Liao-Chang-Wei-Kang combined with 5-fluorouracil inhibits IL-6/STAT3 pathway to exert inhibition of colitis-associated colon cancer inhibition of colitis-associated colon cancer.

湖南本土牡丹种质资源的调查与收集

为了进一步开发与利用湖南牡丹,在前人的基础上再次开展了湖南牡丹资源的调查收集工作。结果显示:此次调查共收集到湖南本地牡丹资源19份,其中粉色系5份,紫色系3份,红色系2份,白色系5份,绿色系1份,杂色系2份,花叶系1份;花型主要有单瓣型、荷花型、菊花型和球花台阁型。最后对湖南本地牡丹资源的保护和利用提出了建议。
