GOS Ameliorates Nonalcoholic Fatty Liver Disease Induced by High Fat and High Sugar Diet through Lipid Metabolism and Intestinal Microbes

The treatment of nonalcoholic fatty liver disease (NAFLD) remains very challenging. This study investigated the therapeutic effect of galactose oligosaccharide (GOS), an important prebiotic, on NAFLD through in vivo and in vitro experiments and preliminarily explored the mechanism by which GOS improves liver lipid metabolism and inflammation through liver and intestinal microbiological analysis. The results of mouse liver lipidomics showed that GOS could promote body thermogenesis in mice with high-fat and high-sugar diet (HFHSD)-induced NAFLD, regulate lipolysis in liver fat cells, and accelerate glycine and cholesterol metabolism. GOS dose-dependently reduced the contents of total cholesterol (TC) and triglyceride (TG) in cells and reduced the accumulation of lipid droplets in cells. GOS also reduced the Firmicutes/Bacteroidetes ratio and altered the composition of the intestinal microbiota in mice fed a HFHSD. GOS can improve liver lipid metabolism and intestinal structure of NAFLD. These results provide a theoretical and experimental basis supporting the use of GOS as a health food with anti-NAFLD functions.     

When muscle quivers and undulates

We describe a patient who presented with fatigue and pulling sensation in his lower limbs. He had continuous muscle contractions over his trunk (myokymia) which pointed towards the diagnosis of Isaacs syndrome which was confirmed by strongly positive CASPR2 antibodies in blood.     

红花化学成分的研究

红花为菊科植物红花（ＣａｒｔｈａｍｕｓｔｉｎｃｔｏｒｉｕｓＬ．）的干燥花，是重要的活血化瘀中药之一［１］。红花有降血压、降血脂等作用，临床上用于治疗冠心病、高血压等疾病［２］。为阐明红花的活性成分，我们曾以药理活性为指标，对其化学成分进行研究，报道...     

视神经周围炎的研究进展

视神经周围炎(OPN)是指涉及视神经鞘膜的一系列病理性炎症.OPN的经典三联征包括单侧视神经病变伴随疼痛和/或视盘水肿,此病症与其它视神经病变相似,导致诊断延迟和治疗欠佳.2016年1月,我们对发表于Medline和Ovid数据库的关键词为“视神经周围炎”的各种语言的文献进行了检索,共查找到60篇文献,发表于1956-2015年.两位作者(Tai ELM和Tevaraj JMP)分别对论文摘要进行了独立筛选,并筛选出相关文章.本次综述,我们强调OPN的特点,特别是OPN和视神经炎之间的临床差异.虽然大多数OPN的病例是特发性的,但仍需进行调查以排除特异性感染和继发性OPN的炎症原因.MRI是非常重要的检查方法,由于OPN视神经周围炎症的影像学诊断.糖皮质激素治疗可使症状与体征迅速好转,长期口服糖皮质激素并慢速递减可以降低复发的风险.     

直肠癌Miles术后会阴部切口感染的原因分析

目的:研究直肠癌术后会阴部切口感染的原因。方法:120例直肠癌患者均采用标准的Miles手术方式。A组:关闭盆底,经右下腹骶前间隙双套管负压吸引,间断夹闭尿管(5 d)的患者30例;B组:关闭盆底,经右下腹骶前间隙单管引流,间断夹闭尿管(5 d)的患者30例;C组:关闭盆底,经右下腹骶前间隙双套管负压吸引,持续开放尿管(5d)的患者30例;D组:不关闭盆底,经右下腹骶前间隙双套管负压吸引和间断夹闭尿管(5 d)的患者30例。结果:A、B、C、D组会阴部切口感染率分别为13.3%,23.3%,19.7%和20.0%。A组与B组、A组与C组、A组与D组比较,差异均有统计学意义(χ2=1.105,P<0.05)。结论:会阴部切口感染与术后骶尾前间隙积液引流是否通畅、骶尾前间隙残腔是否能及时闭合、盆底腹膜是否关闭均有关。     

Evaluation of the anti-proliferative properties of selected psoriasis-treating Chinese medicines on cultured HaCaT cells

Psoriasis is a chronic inflammatory skin disorder, which affects approximately 2-3% of the population worldwide. The current conventional therapy cannot offer satisfactory clinical results for most of the patients, largely due to the fact that many anti-psoriatic drugs have serious side effects and psoriasis is prone to developing drug resistance after long term exposure. Traditionally, Chinese herbal medicine has been extensively used to treat psoriasis and produced promising clinical results; however, its underlying mechanisms of action have not been systematically investigated. The aim of this study was to investigate those Chinese medicinal materials, which are commonly prescribed in Chinese medicine practice for psoriasis, for their anti-proliferative effects on HaCaT cells in vitro. Sixty Chinese medicinal materials were selected and extracted with 80% aqueous ethanol. The dry extracts were evaluated for their anti-proliferative activities by microplate SRB and MTT assays. Three Chinese medicinal materials i.e. the root of Rubia cordifolia L. (Rubiaceae), Realgar and the rhizome of Coptis chinensis Franch. (Ranunculaceae) were found to have significant anti-proliferative effects, with IC(50) being 1.4, 6.6 and 23.4 microg/ml, respectively as measured by MTT assay. While Realgar was also able to modestly inhibit the growth of Hs-68 cells in vitro, Rubia cordifolia and Coptis chinensis did not exert cytotoxicity to this human fibroblast cell line.     

三磷酸腺苷氯化镁对肺癌细胞(A549)端粒酶活性的影响

目的:探讨三磷酸腺苷氯化镁(ATP-MgCl2)对肺腺癌细胞的影响及其作用机理.方法:采用连续细胞记数方法观测ATP-MgCl2对A549肺腺癌细胞生长的抑制情况,应用端粒重复序列扩增法(TRAP)观察ATP-MgCl2对癌细胞端粒酶活性的影响,并与ATP作对比.结果:ATP-MgCl2显著抑制癌细胞生长(P＜0.01),且使大量癌细胞死亡,而加药后前两天ATP-MgCl2的抑制、杀伤癌细胞程度较ATP明显(P＜0.05).ATP-MgCl2组和ATP组的端粒酶阳性表达率明显低于对照组(P＜0.01),而前两者间无明显差异(P＜0.05).结论:ATP-MgCl2对肺腺癌细胞有抑制、杀伤(细胞毒)作用.其抗癌作用机理与ATP相似,与抑制癌细胞端粒酶活性有关.MgCl2与ATP结合形成一种活性复合物,增强了ATP的抗癌作用,ATP-MgCl2具有较好的临床应用价值.
