目的:观察隔药灸对肿瘤坏死因子-α(TNF-α)-肿瘤坏死因子受体相关死亡结构域(TRADD)-Fas相关的死亡结构域(FADD)途径介导克罗恩病(Crohn's disease,CD)肠上皮细胞凋亡的影响,探讨其作用机制。方法:将48只SD雄性大鼠随机分成正常组、模型组、隔药灸组和西药组,每组12只。采用2,4,6-三硝基苯磺酸(TNBS)制备CD模型,造模成功后隔药灸组采用隔药饼灸"天枢""气海"穴,每日1次,每次每穴隔药灸2壮,共灸10d。西药组采用美沙拉嗪灌胃,每日2次,每次2mL,共灌胃10d。治疗结束后取各组大鼠结肠上皮组织,分离、纯化和培养结肠上皮细胞建立体外肠上皮细胞屏障模型,将100ng/mL TNF-α分别与各组肠上皮细胞孵育培养24h,应用荧光黄透过率检测各组肠上皮细胞屏障通透性,Western blot法检测各组肠上皮细胞凋亡途径相关蛋白肿瘤坏死因子受体1(TNFR1)、TRADD、受体作用蛋白1(RIP1)、FADD、锌指蛋白A20(A20)表达以及流式细胞术观察各组肠上皮细胞凋亡情况。结果:与正常组比较,模型组的荧光黄透过率显著升高(P0.001),结肠上皮细胞TNFR1、TRADD、RIP1表达量明显升高(P0.01),A20表达量明显降低(P0.01),细胞凋亡率显著增高(P0.001)。与模型组比较,隔药灸组和西药组的荧光黄透过率显著降低(P0.001),结肠上皮细胞TRADD、RIP1、FADD表达量明显降低(P0.01),A20表达量明显升高(P0.01),结肠上皮细胞凋亡率显著降低(P0.001)。结论:隔药灸可能是通过调控TNF-α介导CD肠上皮细胞凋亡途径的异常,达到保护或修复CD肠上皮屏障损伤之效应。 相似文献

中医专业学位研究生住院医师规范化培训(以下简称"规培")是对临床型研究生教育的重大改革,是提高专业学位研究生教育水平的重大举措,对提高我国临床医师的整体职业素质具有重要意义.现阶段我校专业学位研究生规培教学工作刚刚起步,在科室安排、培训考核、课程设置及导师带教等方面尚存在一些问题,需逐步探索和完善.本文以我校针灸推拿专业临床型研究生规培为例,针对培训实施过程中存在的突出问题进行分析并提出具体的有针对性的建议,以期规范研究生规培工作,提高我校研究生培训质量,培养出高素质、高层次医学专业人才. 相似文献

文题释义:自噬:是一个吞噬自身细胞质蛋白或细胞器并使其包被进入囊泡,并与溶酶体融合形成自噬溶酶体,降解其所包裹的内容物的过程,以此实现细胞本身的代谢需要和某些细胞器的更新。
表观遗传:是指DNA序列不发生变化,但基因表达却发生了可遗传的改变,主要包括DNA甲基化、组蛋白修饰、染色质重塑以及非编码RNA的调控,这种改变在细胞发育和增殖过程中能稳定的传递。
背景:炎症性肠病是一种与肠道自身免疫相关的慢性炎症性疾病,自噬是促进免疫调节的细胞途径,相关基因的表达异常与肠道炎症以及免疫反应关系密切,而表观遗传修饰对炎症性肠病自噬的调控机制尚未阐明。
目的:文章旨在对表观遗传修饰在炎症性肠病自噬中的调控作用作一介绍,以期探讨炎症性肠病自噬的发生机制。
方法:检索PubMed数据库,检索时限1998年1月至2019年4月,检索关键词为“inflammatory bowel disease,autophagy,autophagy related genes,epigenetic modification,DNA methylation,histone modification,chromatin remodeling,miRNA”,选择61篇符合标准的文献。
结果与结论:表观遗传(DNA甲基化、组蛋白修饰、染色质重塑、非编码RNA)可通过修饰炎症性肠病的易感基因ATG、IRGM等来调控肠道炎症、免疫以及自噬,从而介导炎症性肠病的发生和发展。

Objective
To analyze the meridian and acupoint-selection patterns in acupuncture-moxibustion treatment of polycystic ovarian syndrome (PCOS) by data mining technique, for exploring acupoints that could be effective for PCOS and providing suggestion and reference in selecting acupoints for the acupuncture-moxibustion treatment of PCOS.Methods
Literatures related to the acupuncture-moxibustion treatment of PCOS published before April 2018 were collected. By a self-made data mining program developed using Microsoft Excel 2007, a database of acupuncturemoxibustion treatment of PCOS was then established. The correlation analysis was performed for the frequency of use of acupoints and acupoint groups. Cluster analysis was also conducted.Results
A total of 92 articles were recruited finally. Sanyinjiao (SP 6), Conception Vessel and chest-abdomen region ranked the top on the list of the most frequently used acupoints, meridians and regions, respectively. Correlation analysis showed that the acupoint group with the highest confidence was Sanyinjiao (SP 6) and Zusanli (ST 36), and the group with the highest support was Sanyinjiao (SP 6) and Guanyuan (CV 4). Cluster analysis revealed five effective clusters: Guanyuan (CV 4) and Sanyinjiao (SP 6); Zhongwan (CV 12) and Tianshu (ST 25); Zhongji (CV 3), Zusanli (ST 36) and Qihai (CV 6); Xuehai (SP 10), Shenshu (BL 23), Taichong (LR 3) and Guilai (ST 29); Ganshu (BL 18), Taixi (KI 3), Yinlingquan (SP 9) and Pishu (BL 20).Conclusion
According to the confidence and support report, Sanyinjiao (SP 6) and Zusanli (ST 36) or Sanyinjiao (SP 6) and Guanyuan (CV 4) are recommended in acupuncture-moxibustion treatment of PCOS, with adjunct points selected for different patterns, e.g. Zhongwan (CV 12) and Tianshu (ST 25) for tonifying spleen and expelling dampness; Zhongji (CV 3) and Qihai (CV 6) for supplementing qi and cultivating blood; Xuehai (SP 10), Shenshu (BL 23), Taichong (LR 3) and Guilai (ST 29) for tonifying kidney and dissolving stasis; Ganshu (BL 18), Taixi (KI 3), Yinlingquan (SP 9) and Pishu (BL 20) for tonifying kidney and spleen and regulating liver.6.

<正>目前针灸科在临床上治疗脑部疾病时,多重灸头部穴位,现今施灸于头部时多采用艾条悬灸,因其作用温和且容易控制温度,在各种灸法中占主要地位。然而,对于头部这一特殊部位,施灸时需一手执艾条,另一手拨开头发进行艾灸,耗费精力体力,又易烧到头发,作用部位仅为一点,灸量不足以达到灸治目的。《医宗金鉴·刺灸心法要诀》:"凡灸诸病,必火足气到,始能求愈。"足够的灸量,才可以产生灸感,在灸感的刺激下,灸效才可产生~([1])。针对上述情况,笔者为克服现有技术之缺陷,设计出头部保健艾灸器(国家实用新型专利号20152113521.4),现报道如下。 相似文献
