The effects of miR-30c-1-3p regulating group ⅡA secretory phospholipase A2(sPLA2-ⅡA)expression on the pathogenic mechanism of atherosclerosis [PDF]

open access: yes, 2015
动脉粥样硬化(Atherosclerosis,AS)是急性冠脉综合症、脑卒中等众多心脑血管疾病共同的病理基础。sPLA2-ⅡA在动脉粥样硬化病变处含量明显增多、活性显著增强,同时伴随中性粒细胞的增多。sPLA2-ⅡA以酶的催化水解作用和作为致炎因子的促炎症反应双重生物学作用参与AS发生发展的各个阶段。 MicroRNA(miRNA)是近年发现广泛存在于真核细胞中的高度保守的、非编码单链小分子RNA,具有最广泛的基因调节功能,参与机体多种生理、病理过程的调控。 我们运用miRNA靶基因预测软件发现miR ...

Arsenic Trioxide Induces T cell Apoptosis and Prolongs Islet Allograft Survival in Mice [PDF]

open access: yes, 2015
目的:作为一种最有潜力的I型糖尿病的治疗方法,胰岛移植目前已经应用于临床。然而,免疫因素特别是T细胞介导的移植物活性损伤与功能丧失是胰岛移植应用的一大障碍。一直以来,科学家们都在寻找适用于胰岛移植的新型免疫抑制剂。三氧化二砷是临床上治疗早幼粒细胞白血病的特效药,最近被证明能够抑制同种异体心脏移植排斥反应。在此基础上,本文研究了三氧化二砷对同种异体胰岛移植免疫排斥的抑制作用,以及三氧化二砷与雷帕霉素联合诱导免疫耐受的可能作用机制。 方法:我们首先检测了三氧化二砷对胰岛细胞的毒性作用 ...

Cytological evaluation, culture and genomics to evaluate the microbiome in healthy rabbit external ear canals

open access: yesVeterinary Dermatology, Volume 35, Issue 5, Page 479-491, October 2024.
Background – Lop‐eared rabbits may be predisposed to otitis externa (OE) as a consequence of their ear conformation. Although otoscopy, otic cytological evaluation, and culture are valuable tools in dogs and cats, published data on rabbits remain lacking. Hypothesis/Objectives – This study aimed to assess the utility of otoscopy and cytological results

Maintenance of Long-term Tolerance by T Regulatory Cells in a Mouse Model of Heart Transplantation [PDF]

open access: yes, 2015
目的:自20世纪以来,临床上心脏移植的一年生存率已经达到90%,但是移植后的慢性排斥以及长期存活仍面临巨大挑战,目前临床上所用的免疫抑制剂多数都必须终身用药,从而会产生多种副作用,危害受者的健康,影响患者的生活质量,所以如何诱导移植物的长期耐受是器官移植面临的重大难题。调节性T细胞是具有免疫调节功能的T细胞亚群,在移植后诱导和维持免疫耐受方面发挥重要作用。其中,CD4+CD25+Foxp3+T细胞(CD4+Foxp3+Treg)主要通过细胞接触发挥调节作用,而CD4+IL-10+IL-4-T细胞(Tr1)

A pilot study of antimicrobial effects and ototoxicity of a Norway spruce (Picea abies) resin‐based canine otic rinse product

open access: yesVeterinary Dermatology, Volume 35, Issue 3, Page 325-336, June 2024.
Background – Norway spruce (Picea abies) resin‐based products are used in human medicine. A resin‐based otic rinse also could be useful in supportive care of canine otitis externa (COE), yet information on its antimicrobial effect against canine pathogens or ototoxicity is lacking.

Combination CXCL9 Antibodies with FTY720 Prolongs the Survival of Cardiac Retransplantation Allografts in a Rat Model [PDF]

open access: yes, 2015
实验目的 趋化因子的基因表达上调和随之发生的T淋巴细胞在移植物中的募集发生在 同种异体器官移植急性排斥反应和器官移植血管病变的早期。在本研究中我们尝 试使用联合趋化因子CXCL9抗体和FTY720的免疫抑制方案,抑制记忆性T细胞 的增殖,调节T细胞细胞因子的分泌,加速淋巴归巢,减少再次心脏移植物中的 淋巴细胞浸润,从而延长大鼠再次心脏移植物的存活时间。 实验方法 BN大鼠作为实验受体,LEW大鼠作为实验供体。颈部套管法异位心脏移植术 后4周进行再次腹部异位心脏移植术。根据不同的免疫抑制方案将大鼠分为四组。

Experimental Study on the Effects of Ciji Hua’Ai BaoSheng Decoction on Cytokines of Tumor Chemotherapy Model Mouse with H22 Hepatoma Carcinoma Cells [PDF]

open access: yes, 2015
背景:癌症是一类严重危害人类生命健康的致死性疾病。化疗(Chemotherapy)是癌症临床治疗的经典方法之一,但化疗药物无选择性杀伤肿瘤细胞的同时,也杀伤正常细胞,带来较严重的副作用,严重影响患者生存质量及预后。慈济化癌保生汤(CHBF)是导师王彦晖教授临床多年诊治癌症所创立的经验方,该方用于癌症患者化疗后的长期调理,具有提高生存质量,改善体质、降低复发率及延长生存期的作用。前期研究证实[1]:慈济化癌保生颗粒能延长移植瘤和腹水瘤化疗模型小鼠的生存期,有一定的抑制化疗后移植瘤生长的作用 ...

慢性房颤患者心房组织中SOCS-1和IL-23水平的动态变化与房颤的关系

open access: yesZhongguo shiyan zhenduanxue, 2017
近年来,有关炎症与炎症因子在房颤(AF)发病过程中的作用越来越引起人们重视。白细胞介素-23(IL-23)主要是由活化的单核巨噬细胞及树突状细胞分泌的炎症细胞因子,与许多炎症疾病有关,有学者发现它参与了AF的病理过程[1]。细胞因子信号转导负调控因子-1(SOCS-1)是由炎症因子激活JAK/STAT通路产生的一种炎症因子,它反过来通过抑制该通路对炎症反应有负调控作用,本文对慢性AF患者心房组织中SOCS-1和IL ...
