    • 摘要: 随着胸部CT筛查的广泛开展,肺结节检出率呈不断上升的趋势。检出的病灶中大多尺寸较小、形态学特征不明显,诊断存在一定难度。在当前的医疗环境下肺结节存在过度诊断的情况频繁复查也有潜在的辐射致癌风险。其中,磨玻璃密度结节作为筛查结节的常见类型其发病率高、病因复杂、演进机制不明、与实性病变的发展和转归存在较大差异,故应区分对待。

    • 摘要: 为了探讨miR-200b在辐射诱导胸腺淋巴瘤中的作用与机制,采用全身分割照射建立BALB/c小鼠辐射诱导胸腺淋巴瘤模型,检测miR-200b表达情况;构建过表达与敲低miR-200b细胞模型,检测该miRNA对细胞增殖、凋亡情况的影响;随后通过miRNA数据库TargetScan分析miRNA潜在靶点,并用双荧光素酶报告系统进行验证,最后采用Spearman方法分析TBK1蛋白与miR-200b表达水平的相关性。结果显示,小鼠辐射诱导胸腺淋巴瘤组织中miR-200b表达下调,过表达miR-200b可明显抑制细胞增殖,增加细胞凋亡,下调miR-200b可促进细胞增殖,减少细胞凋亡;双荧光素酶报告系统提示miR-200b以3′UTR依赖的方式靶向作用于TBK1。在辐射诱导胸腺淋巴瘤样本中,miR-200b表达和TBK1蛋白水平之间存在负相关关系,且TBK1过表达可部分逆转miR-200b介导的细胞生物学效应。结果表明,辐射诱导胸腺淋巴瘤组织中miR-200b表达下调,其直接靶点TBK1表达上调;过表达miR-200b可明显抑制胸腺淋巴瘤细胞增殖,增加细胞凋亡。提示靶向调控miR-200b/TBK1,有望成为防治辐射诱导胸腺淋巴瘤的潜在新途径。

    • 摘要: 目的研究医用诊断X射线工作者接触小剂量辐射诱发恶性肿瘤的表现和发病危险。方法采用回归性队列研究,收集1997—2011年间医用X射线工作者和非X射线工作者的癌症发病资料,用Epicure软件中DATAB程序计算人年数,采用AMFIT估算照射组恶性肿瘤的发病相对危险(RR)及其95%CI。结果研究共调查898人,其中,照射组414人,累计观察5 560人年;对照组484人,累计观察6 414人年。队列成员失访率为3.54%。队列共发现新发恶性肿瘤88例,其中,照射组49例,对照组39例。与对照组相比,照射组全癌的RR值为1.47(95%CI:0.98~2.38),无统计学意叉。照射组发病率显著性上升的为肺癌(RR=2.00,95%CI:1.16~2.72)和胃癌(RR=2.34,95%CI:1.37~2.93),有统计学意义。另外,照射组肝癌、胰腺癌、直肠癌、子宫肌瘤、食管癌和结肠癌发病率虽然有上升趋势,但与对照组相比没有显著性差异(P<0.05)。结论苏州市医用诊断X射线工作者恶性肿瘤发病率与其他非X射线工作者并无太大差异,可能与苏州市医疗机构重视辐射防护,加强个人防护有关。

    • 摘要: 应用美国电离辐射生物效应委员会研发的日本原子弹爆炸幸存者辐射致结肠癌危险模型,选用相乘相加混合转移模型用于人群间危险转移,结合2012我国肿瘤登记年报发布的2009年结肠癌基线发病率,估算了我国人群辐射致结肠癌危险系数。在进行人群间转移危险过程中,根据肿瘤登记年报年龄组别发病率,进行曲线拟合,估算年龄别发病率。估算出我国人群辐射致结肠癌超额相对危险系数男性为0.74/Sv,女性为0.46/Sv(30岁受照,60岁患癌)。受照年龄越小,患癌年龄越小,此系数越大。我国人群辐射致结肠癌危险系数高于日本原子弹爆炸幸存者,二者随性别-年龄变化趋势相同。
    • 摘要: 谣言止于智者,流言止于知者。2015年年终,我们总结并揭秘一些近年来流传于坊间的有关计量的流言。其中有的流言,十多年间反复冲击人们的眼球、强化着人们的记忆,大有不上头条不收兵之势。计量流言披着“科学”的外衣,让人难辨真假,人们对其往往抱着“宁可信其有,不可信其无”的心态,以讹传讹。

    • 摘要: 目的 通过日本原爆人群的辐射致白血病危险估算中国人群白血病的超额相对危险(ERR)值,探讨合适的人群危险转移方法.方法 危险计算使用BEIRⅦ辐射致癌计算模型及人群危险转移模型,中国人群率采用《2012中国肿瘤登记年报》中2009年中国肿瘤基线发病率.通过不同国家人群率的比较,来调整权重系数.结果 得到经人群转移后的中国人群白血病ERR值;对中国人群男性拟定相加模型权重系数为0.2、相乘模型为0.8,对女性相加模型权重系数为0.15、相乘模型为0.85.结论 在辐射致白血病危险人群转移中从总体考虑调整权重系数,得到适于估算中国人群辐射致白血病危险的人群ERR值.应用新的中国人群发病率将辐射致白血病危险直接从日本人群转移到中国人群,得出适于中国人群的辐射致白血病危险的转移方法.%Objective To estimate the averaged excess relative risk(ERR) in Chinese population based on the radiogenic cancer risk of leukemia in Japanese atomic bomb survivor cohort,and to discuss proper method suitable for risk transfer between populations.Methods Based on BEIR Ⅶ radiogenic cancer model and population transfer model,and the 2009 Chinese leukemia baseline rates given in 2012 Chinese Cancer Registry Annual Report,comparison was made of population incidences in seveal countries to adjust the weighting factors.Results The ERR of three subtypes of leukemia as a whole was obtained,and the weighting factors for risk transfer model was assumed.The additive factor for male was 0.2,and the multiplicative factor was 0.8,while the additive factor for female was 0.15,and the multiplicative factor was 0.85.Conclusions For the risk transfer between populations,weighting factor was adjusted as a whole to obtain the ERR value for estimating the risk to Chinese population.The risk transfer method suitable for Chinese population was obtained by using the incidence rate available for Chinese population to directly transfer radiation-induced leukemia risk to Chinese from Japanese.

    • 摘要: Objective To study the relationship between the risk of malignant tumor and occupational radiation factor among medical diagnostic X-ray workers in Jiangsu province.Methods The retrospective and prospective cohort studies were adopted to investigate the incidence of cancer.Eligible medical diagnostic X-ray workers from the department of radiology in hospitals were selected and assigned into exposure group,while other medical workers from the departments of Internal Medicine,Ear-NoseThroat (ENT) or Pediatrics who attended work at the same period in the same hospital but not engaged in radiation work were regarded as control group during 1950-2011 in Jiangsu province.We calculated the total person-year and analyzed the relative risk (RR) of malignant tumor using Poisson regression model.Results 7 703 participants (3 961 in exposed group and 3 742 in unexposed group) were recruited and followed up,with a total of 315 309 person years and the lost follow-up rate was 6.92% (533/7 703).During the follow up period,a total of 819 tumor cases were identified (771 were malignant tumors).We found the significant relationship between the risk of malignant tumor and occupational radiation factor,and the RR of solid cancer and total malignant tumor were 1.31 (95% CI:1.11-1.55) and 1.33 (95% CI:1.13-1.57),respectively.In addition,the risk of lung cancer in medical diagnostic X-ray workers was significantly higher than that in control group (RR =1.45,95% CI:1.00-2.09).Conclusions The incidence risk of lung cancer,solid caner and total malignant tumors in medical diagnostic X-ray workers was significantly higher than that in the control group,which might be associated with occupational exposure to ionizing radiation.%目的 研究江苏省医用X射线工作者的职业性照射因素与恶性肿瘤发病风险之间的关系.方法 采用回顾性和前瞻性队列相结合的研究方法,选取省内1950-1980年间在医院放射科工作的医用X射线工作者为放射组;同一医院同时期未从事过放射工作的内科、五官科、儿科等医务人员为对照组形成调查队列.计算该随访队列1950-2011年累计观察人年数,并采用Poisson回归模型,计算调整性别、年龄等因素后医用X射线工作者的各种恶性肿瘤的相对危险.结果 本次队列共完成随访7 703人,其中放射组3 961人,对照组3 742人,总体观察人年数为315 309人年,失访率为6.92% (533/7 703).1950-2011年期间肿瘤患者共计819人(恶性肿瘤771人),放射组恶性肿瘤发病风险明显高于对照组,实体癌和全部恶性肿瘤的相对危险度RR分别为1.31 (95% CI:1.11 ~1.55)和1.33(95% CI:1.13~ 1.57).其中放射组罹患肺癌的相对危险度明显提高(RR=1.45,95% CI:1.00 ~2.09).结论 江苏省医用X射线工作者罹患肺癌、实体癌以及全癌的相对危险度明显提高,可能与其长期接受慢性小剂量职业照射有关.

    • 摘要: MicroRNAs ( miRNAs ) are endogenous non-coding RNAs , which can degrade their target mRNAs or inhibit their translation by binding to their target mRNAs specifically. MiRNAs act as post-transcriptional regulators of gene expression, and then are involved in diverse physiological activities. Many studies has shown that miRNAs are closely related with radiation carcinogenesis, radiosensitivity, radioresistance and radiation-induced bystander effects, and have being a hotspot in radiation-medicine research. This review focuses on the introduction of miRNAs and their applications in radiation medicine.%microRNAs(miRNAs)是一类内源性的非编码RNA,通过与靶mRNA特异性的结合而导致靶mRNA降解或抑制其翻译,对基因进行转录后调控,进而影响各种生命活动。大量研究表明,miRNAs与辐射致癌效应、辐射增敏效应、肿瘤辐射抗拒和辐射旁效应密切相关,已成为放射医学研究的热点。笔者就miRNAs及其在放射医学研究中的应用作一综述。
