Neuro Oncol.:糖尿病、抗糖尿病药物的使用与神经胶质瘤风险的关联

2015-06-22 范伟译 MedSci原创

背景:先前流行病学研究表明糖尿病和神经胶质瘤的风险之间存在逆关联,但潜在的机制,包括抗糖尿病药物的使用是未知的。方法:因此,我们采用临床实践研究数据链(CPRD)进行病例匹配对照分析。我们确定了1995年到2012年间诊断的神经胶质瘤病例,在临床实践研究数据链CPRD中,每个案例在年龄,性别,总有效时间,普通全科,年活跃历史上有10例对照病例。我们采用条件逻辑回归方程来估计优势比(ORs)与95%

背景:先前流行病学研究表明糖尿病和神经胶质瘤的风险之间存在逆关联,但潜在的机制,包括抗糖尿病药物的使用是未知的。

方法:因此,我们采用临床实践研究数据链(CPRD)进行病例匹配对照分析。我们确定了1995年到2012年间诊断的神经胶质瘤病例,在临床实践研究数据链CPRD中,每个案例在年龄,性别,总有效时间,普通全科,年活跃历史上有10例对照病例。我们采用条件逻辑回归方程来估计优势比(ORs)与95%的置信区间CIs,调整的身体质量指数和吸烟情况。

结果:我们确认了2005例病例和20050个对照病例。糖尿病与神经胶质瘤的风险降低有关(OR = 0.74;95%置信区间CI = 0.60-0.93),特别是胶质母细胞瘤(OR = 0.69;95%置信区间CI = 0.51-0.94)。胶质母细胞瘤风险降低与糖尿病男性(OR = 0.60;95%置信区间CI = 0.40 -0.90)有明显关联,其中最明显的有糖尿病患者长期持续时间(OR > 5 vs 0年= 0.46,95% CI = 0.26 -0.82)或血糖控制差(糖化血红蛋白的OR≥8 vs < 6.5% = 0.20,95% CI = 0.06 -0.70)。相比之下,在女性中,糖尿病对胶质母细胞瘤风险的影响不存在(OR = 0.85;95%置信区间CI = 0.53 -1.36)。神经胶质瘤与使用二甲双胍(OR≥30 vs 0处方= 0.72;95%置信区间0.38 -1.39),磺酰脲类药物(OR = 0.71;95%置信区间CI = 0.39 -1.30),或胰岛素(OR = 0.79;95%置信区间CI = 0.37 -1.69)没有明显的关联。

结论:抗糖尿病治疗似乎与神经胶质瘤无关,但长期糖尿病持续时间和增加的糖化血红蛋白都显示神经胶质瘤的风险降低了。男性相比于女性更强有力的发现表明雄激素水平较低并发糖尿病可作为一个生物机制。

Nat Immunol:糖尿病治疗药物可增强免疫抗击癌症

近日,来自Pasteru和Inserm研究所的科学家通过实验研究成功地促进了免疫细胞向肿瘤组织的浸润过程,在肿瘤组织内部诱导了免疫系统应答,阻断了肿瘤生长。在这项发表在国际学术期刊Nature Immunology的文章中,科学家们证明利用上述过程再结合一些免疫治疗方法可以有效杀伤癌细胞。趋化因子是一类能够吸引免疫细胞向炎症组织迁移的小分子物质,在肿瘤发展,感染等疾病过程中发挥重要作用,但这些小分

你得前驱糖尿病了吗?

研究人员认为发展成2型糖尿病之前,存在一个前驱糖尿病,这时候的血糖水平处于“灰色地带”,高于正常值但低于糖尿病的血糖值。根据美国疾病预防与控制中心的介绍,大约三个美国成年人中就有一个处于前驱糖尿病,但只有11%左右的人意识到他们的病情。前驱糖尿病是一个很严重的问题,因为许多糖尿病的发病过程——包括神经损伤,眼部问题和心脏病等,在糖尿病还没有被诊断出来的时候就已经开始在我们的体内酝酿了。如果不对其进

Nat Med:细胞“对话”帮助开发糖尿病新疗法

有时候倾听对话或许可以让我们获取更多的信息,近日一篇刊登于国际杂志Nature Medicine上的研究论文中,来自加州大学戴维斯分校的研究人员通过研究表示,细胞间的交谈或可控制机体对糖类的反应,理解这种细胞间的交流或可帮助我们理解糖尿病的发病机理,并且帮助开发治疗糖尿病的新型疗法。 研究者表示,他们在胰腺细胞间鉴别出了一种关键的“对话”,即一种名为尿皮素3的激素,尿皮素3可以同胰岛素一同释

Diabetologia:冻存胰岛潜在优势,为期20年的研究

目的: 低温(-196℃)冻存胰岛有着潜在的优势,包括在未来对这些活性胰岛进行更深入的探索。我们对冻存胰岛在试管内和活体内的功能进行了为期20年的研究。 方法: 1991年至2001年人类胰岛进行冻存,2012年至2014年进行解冻。通过免疫染色,膜片钳电生理学,胰岛素分泌,转录组分析,以及移植到糖尿病小鼠模型(通过链脲菌素(STZ)诱导建模)中对胰岛功能经行研究。 结果: 冻存时间为17.6

Mol Cell Endocrinol :弱骨强代谢——指向糖尿病的新治疗

骨骼脆弱显然不是一件好事,不过科学家们怀疑,基因工程小鼠的骨骼和身体的其余部分之间的某处联系中,可能隐藏了一个答案,能够帮助肥胖者避免一些由肥胖带来的健康困扰。佐治亚大学医学院的研究人员最近报告说,拥有脆弱骨骼的小鼠有很强的代谢能力,即使是在高脂肪饮食条件下。这篇研究发表在最近的Molecular and Cellular Endocrinology杂志。 McGee-Lawrence博士是该研
