Cell Stem Cell:低剂量辐射(如CT或X光照射)甚至会促进致癌细胞!

对健康组织来说,相当于三次CT扫描的低剂量辐射,曾被认为是安全的,但最近,科学家们发现,低剂量的辐射居然能使致癌细胞比正常细胞更具有竞争优势。Wellcome Sanger 研究所和剑桥大学的研究人员研究了低剂量辐射对小鼠食道的影响。结果发表在7月18日的Cell Stem Cell杂志,表明低剂量的辐射能促进致癌细胞在健康组织中的扩散。

研究小组发现,低剂量辐射会增加通常与癌症相关的p53突变细胞数量。积极的是,在辐射照射前给予小鼠一种抗氧化剂,可促进健康细胞生长,从而在竞争中超过对手,取代p53突变细胞。

研究人员建议,在评估辐照安全时应考虑这种风险。这项研究提示了开发无毒预防措施的可能性——通过加强我们的健康细胞来超越和根除致癌细胞,从而降低患癌症风险。

每天我们都会接触各种电离辐射源,包括土壤和岩石中的自然辐射,以及重要的医疗检查,如CT扫描和X射线。

低剂量的辐射,例如医学成像时暴露在不同射线下,因为几乎不会造成DNA损伤,并且对长期健康影响很小,被认为是安全的。到目前为止,我们对暴露于低水平辐射的其他影响仍然未知,这意味着了解低剂量辐射的真正风险十分困难。

研究人员先前证明过,在我们的正常组织(如皮肤)中,突变细胞与健康细胞无时无刻不在竞争生存空间。健康组织中有能够致癌的突变细胞,也包括那些p53突变的细胞,随着年龄的增长,这些突变细胞的数量不断增加,最终形成癌症的细胞却很少。

在新研究中,研究人员发现低剂量的辐射有利于食道中的突变细胞。Sanger研究所的研究人员和他们的合作者给小鼠50毫克的辐射剂量(相当于三到四次CT扫描)。结果,p53突变细胞开始扩散并在竞争中超过健康细胞。

该文章的第一作者,Wellcome Sanger研究所的David Fernandez-Antoran博士说:“我们的身体是‘克隆游戏’的集合体,是正常细胞和突变细胞空间争夺的持续战场。我们证明,即使是低剂量的辐射,类似于三次CT扫描的量,也会增加突变细胞的胜率。我们发现了一个由辐射导致的额外潜在的癌症风险,值得大家注意。”

研究人员随后给予小鼠一种非处方抗氧化剂(ROS抑制剂)——N-乙酰半胱氨酸(NAC)——然后再暴露于相同水平的辐射。研究小组发现,这种抗氧化剂可以增加正常细胞的竞争力,根除p53突变细胞。

但是注意,如果不暴露在辐射下,抗氧化剂并不能帮助正常细胞对抗突变细胞。

来自Wellcome Sanger研究所的作者Kasumi Murai博士说:“在将小鼠暴露在低剂量的辐射下之前,给予它们一种抗氧化剂,对健康细胞来说是种提升,以抵抗食道中突变的细胞并使它们消失。然而,我们不知道这种疗法在其他组织中会有什么效果——在其他地方,会不会帮助突变细胞变得更强?据我们所知,参考其他研究,长期单独使用抗氧化剂似乎并不能有效地预防癌症。”

该文章的通讯作者,来自英国剑桥大学的Wellcome Sanger研究所和MRC癌症研究所的Phil Jones教授说:“使用辐射医学成像,如CT扫描和X射线,风险很低,很难测量。这项动物研究帮助我们更多地了解了低剂量辐射的影响及其可能带来的风险。需要更多的研究来了解它们对人体的影响”

研究小组认为,这项研究也强调了开发癌症预防疗法的可能性。求人不如求自己,通过使健康的细胞更健康,它们就能自然地将致癌细胞排出体外,也不会对患者产生任何有毒副作用。

JAHA:电生理手术对患者的辐射暴露问题不容忽视!

本研究的目的旨在大样本病人数据中评估电生理或器械植入术中X线暴露的情况和比较不同技术的房颤消融术对患者的X线暴露情况。本研究纳入了6095例接受电生理检查的患者和2055例器械植入的患者,经过7年时间的分析评估,发现电生理检查的X线暴露量、剂量面积乘积与有效剂量呈逐年下降趋势(p<0.001),通过分析2416例房颤消融术,发现7名不同的有经验的操作者在X线暴露量、剂量面积乘积与有效剂量方面存在明

Brit J Cancer:睾丸癌主动脉辐射后,糖尿病风险研究

在儿童癌症幸存者中,虽然糖尿病风险在胰腺辐射接触后风险增加,其余睾丸癌(TC)生存者之间的相关性还没有调查。最近,有研究人员在2998名1年TC生存者中研究了糖尿病风险,他们均在50岁之前进行睾丸切除和/或放射治疗,时间均在1976年和2007年之间。研究人员将该群体的糖尿病发生率与普通人群比例进行了比较,并利用一个案例群体设计评估了治疗特异性糖尿病风险。研究发现,平均的跟踪调查时间为13.4年,

鼻咽癌放疗后视力下降?当心辐射性眼损伤!

鼻咽癌是我国高发恶性肿瘤之一。特别高发于广东地区,很多朋友戏称它为“广东癌”。鼻咽癌大多对放射治疗具有中度敏感性,放射治疗是目前鼻咽癌的首选治疗方法。

骨科手术的辐射风险我们知道吗?

骨科手术的辐射风险我们知道吗?电离辐射的有害影响已从核工业工作人员中得到充分证实,即使在低剂量下暴露,癌症死亡率也很高。随着荧光透视成像技术的广泛应用,骨科医生和手术室人员的辐射风险增加。研究证实,恶性肿瘤、眼部和甲状腺疾病患病风险的增加与辐射暴露的增加有关。国外有研究评估了医务人员在创伤外科及骨科手术中不同身体部位的暴露情况,结果显示骨科医务人员中恶性疾病的发病率增加。在PubMed,CINAH
