目的观察穴位埋线联合二甲双胍对肥胖型多囊卵巢综合征患者糖脂代谢的影响。方法将84例肥胖型多囊卵巢综合征患者随机分为对照组42例,观察组42例。对照组给予二甲双胍口服,观察组给予二甲双胍口服同时予穴位埋线治疗。分别在治疗前后观察两组患者的体质量指数(BMI)、腰围、空腹胰岛素、胰岛素抵抗指数(HOMA-ZR)及血脂变化,并比较两组临床疗效。结果两组总有效率比较,观察组优于对照组,差异有统计学意义(P0.05)。两组治疗前后BMI、腰围、空腹胰岛素及HOMA-ZR比较,差异有统计学意义(P0.05);治疗后,观察组BMI、空腹胰岛素及HOMA-ZR优于对照组(P0.05),两组腰围比较,差异无统计学意义(P0.05)。两组治疗后血脂水平与治疗前比较,差异有统计学意义(P0.05);治疗后,两组总胆固醇(TC)比较,差异无统计学意义(P0.05),两组甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)比较,差异有统计学意义(P0.05)。结论穴位埋线联合二甲双胍口服能有明显改善肥胖型多囊卵巢综合征患者糖脂代谢水平,提高临床疗效。     

刮痧配合放痧治疗轻度高血压临床观察

目的:观察刮痧配合放痧对轻度(Ⅰ级)高血压病的即刻降压作用。方法:本组轻度(Ⅰ级)高血压患者30例与正常血压者30例进行对照,两组均选取督脉、足太阳经、手阳明经、足阳明经的相关区域和穴位进行3遍刮痧之后再放痧,记录每次刮痧及放痧后的血压值以及每次刮痧后大椎穴区的皮肤温度变化。每周治疗1次,共治疗4次。结果:第1遍、第2遍刮痧和第3遍刮痧以及放痧后均有明显的降压作用(均P<0.01);且刮痧配合放痧的降压作用最为显著(P<0.01);3遍刮痧后的大椎穴区皮肤温度均有显著性升高(均P<0.01)。结论:单纯刮痧或配合放痧对轻度(Ⅰ级)高血压具有较好的降压作用,刮痧的这种降压效应可能与其对体表经络、穴位的温热刺激有关。     

炎症性肠病的自噬与表观遗传修饰

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。 ORCID: 0000-0003-0627-9236(郭娅静) 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程

Comparative study of electroacupuncture and moxibustion in influencing Tianshu (ST 25) regions mast cells in visceral hyperalgesia rats

Objective

To evaluate and compare electroacupunctures (EA) with different parameters and moxibustion at different temperatures influencing the activation of mast cells (MC) in Tianshu (ST 25) regions of visceral hyperalgesia model rats.

Methods

Rats (except for model group) respectively accepted 1 mA or 3 mA EA or moxibustion at 43 °C or 4 °C to stimulate Tianshu (ST 25) points after randomization of the fifty visceral hyperalgesia model rats, and then were compared with that in model and normal groups. Number, degranulation numbers, degranulation rates in Tianshu (ST 25) regions MC of rats in each group were observed using toluidine blue staining. Abdominal withdrawl reflex (AWR) score was used to evaluate the rat visceral hyperalgesia reactions.

Results

Compared with the normal group and the model group, MC numbers (P<0.05, P<0.01, P<0.01, P<0.01), degranulation numbers and degranulation rates (P<0.01, P<0.01, P<0.05, P<0.01) of Tianshu (ST 25) MC in regions tissues in 43 °C and 4 °C moxibustion groups, and 1 mA and 3 mA EA groups all increased significantly. Compared with the model group, AWR scores were significantly lower in 43 °C and 4 °C moxibustion groups, and 1 mA and 3 mA EA groups under the stimulation of 20 mmHg, 40 mmHg, 0 mmHg or 80 mmHg colorectal distension (CRD) (P<0.05 in 1 mA and 3 mA EA groups under the stimulation of 20 mmHg, P<0.01 in the other groups). AWR scores in 43 °C and 4 °C oxibustion groups under the stimulation of 20 mmHg, 40 mmHg, 0 mmHg or 80 mmHg CRD were not significantly different from those in the normal group (all P>0.05); AWR scores in 1 mA EA group under the stimulation of 0 mmHg or 80 mmHg were significantly higher than that in the normal group (P<0.01); AWR score in 3 mA EA group under the stimulation of 0 mmHg was significantly higher than that in the normal group (P<0.01), and AWR scores in 3 mA EA group under the stimulation of 20 mmHg or 80 mmHg were also higher than that in the normal group (P<0.05). AWR scores were higher in 1 mA EA group under the stimulation of 40 mmHg or 80 mmHg than that in 4 °C moxibustion group (P<0.05); AWR score was higher in 3 mA EA group under the stimulation of 40 mmHg than that in 4 °C moxibustion group (P<0.05).

Conclusion

There are differences among EA of different parameters and moxibustion of different temperatures in activating on Tianshu (ST 25) regions MC of visceral hyperalgesia model rats, as well as in improving the visceral hyperalgesia reaction. The effect of 4 °C moxibustion is the most significant.

温和灸肾俞穴、关元穴对肾阳虚老年人衰老症状及外周血Rb蛋白表达的影响

目的观察温和灸对肾阳虚老年人外周血成视网膜母细胞瘤(retinoblastoma,Rb)蛋白表达以及衰老症状的影响,探讨温和灸的抗衰老作用。方法将60～75岁肾阳虚老年人81例随机分为温和灸治疗组41例和衰老对照组40例。温和灸治疗组采用温和灸肾俞穴、关元穴,18次为一个疗程,连续治疗两个疗程。采用积分表法观察温和灸对老年人治疗后综合情况的影响和症状改善情况,并用流式细胞术检测外周血Rb蛋白表达情况。结果 (1)经温和灸治疗,肾阳虚老年人衰老症状积分较衰老对照组疗效显著降低(P<0.01);(2)温和灸第二疗程末疗效较第一疗程末显著提高(P<0.01);(3)温和灸治疗组老年人外周血单个核细胞Rb蛋白阳性表达率显著低于衰老对照组(P<0.01)。结论温和灸可能通过干预肾阳虚老年人外周血Rb表达,改善衰老症状,降低衰老见证积分。     

电针对腹泻型肠易激综合征患者结肠黏膜5-HT、5-HT3R表达的影响

目的:观察电针对腹泻型肠易激综合征患者结肠黏膜5-HT、5-HT3R表达的影响,探讨其作用机制。方法:分别选取给予电针治疗(选取中脘、天枢、气海等穴,针刺后加电刺激,4周为1个疗程)16例和西药治疗(口服地衣芽孢杆菌和黛力新片)15例的腹泻型IBS患者治疗前后的乙状结肠黏膜组织,采用免疫组化法观察两组患者结肠黏膜5-HT、5-HT3R表达情况。结果:电针组和西药组两组患者治疗前结肠黏膜5-HT、5-HT3R阳性面积和光密度(OD)表达均较正常人有显著性升高(P0.01,P0.01);两组患者治疗后均较治疗前有显著性降低(P0.01,P0.01),电针组治疗后结肠黏膜5-HT、5-HT3R阳性面积表达则较西药组明显降低,两组间比较差异有统计学意义(P0.05,P0.05)。结论:电针可能通过显著降低腹泻型IBS患者结肠黏膜5-HT、5-HT3R表达,进而减弱神经介导的胃肠道运动与分泌,提高内脏痛阈,消除肠道过敏,由此改善胃肠道运动功能状态和内脏高敏感性而达到其治疗之目的。
