致癌的

Medical colleges were instructed that if they wished to benefit from the Rockefeller largesse they had better convince 500 million Chinese to throw into the ashcan the safe and useful but inexpensive herbal remedies of their barefoot doctors, which had withstood the test of centuries, in favor of the expensive carcinogenic and teratogenic "miracle" drugs Made in USA, which had to be replaced constantly with new ones, when the fatal side-effects could no longer be concealed; and if they couldn't "demonstrate" through large-scale animal experiments the effectiveness of their ancient acupuncture, this could not be recognized as having any "scientific value".

医学院校被告知，如果它们想从洛克菲勒慷慨的赠与中得到好处，它们必须使五万万中国人民信服地把他们经过多少个世纪检验的赤脚医生安全、有效却又廉价的草药扔到垃圾箱里，让中国人民赞成使用美国制造的昂贵的有致癌、致畸作用的"神"药，当这些药致命的副作用再也掩盖不住的时候，则需要不断地用新药来替代；如果他们不能通过大规模的动物实验来"验证"他们古老的针灸的有效性，这就不能认为有任何"科学价值"。

The bone dosimetric values are influenced by the parameters of skeleton mass.

鉴于骨骼组织不同部位的辐射敏感性存在差异［2］，特别是已确认骨髓的造血干细胞和衬在骨表面上的成骨细胞是骨骼中致癌危险的靶细胞，因而ICRP30号出版物［3］详细介绍了估算骨骼靶器官的吸收剂量的骨剂量学模型，使骨剂量的计算趋向精确。1995年，ICRP又专门编著了用于辐射防护的骨骼解剖和生理参数的70号出版

It is very important to expore the genotoxity of formaldehyde, toxicity mechanism and repair for understanding formaldehyde genotoxicity as well as nosogenesis completely and systematically. In addition, this research will benefit a lot to estimate and improve the indoor air quality by providing scientific foundation and make a safe environmental and occupational concentration standard.

The studies exploring the relationship between HPV infection and laryngealcarcinoma began in 1980s,since then,almost all the research was aimed at theinvestigation of the HPV prevalence in the biopsies,due to differences in thechoice of DNA detection method,cell sampling and the geogen,the prevalenceestimates of HPV have varied accordingly,and led to two different points about therelationship between HPV infection and laryngeal carcinoma:some researchersdemonstrated that a higher HPV prevalence could be found in laryngeal carcinomas(from 50% to 90%)than in benign laryngeal lesions,suggesting a relationshipbetween HPV infection and laryngeal carcinoma;but the other researchers foundthat the isolation of HPV is no greater in the laryngeal cancers(from 5% to 43.3%)than in the normal larynx or benign laryngeal lesions,thereby questioning itsctiological significance,so,the role of HPV in the development of laryngealcarcinomas still remains unclear.

有关HPV与喉癌的研究始于80年代，但20多年来研究模式始终停留在对临床标本进行检测的水平上，由于各家采用的检测手段敏感性不同、标本数量以及来源地域也存在差异，使各家学者对喉癌中HPV阳性率的报道极不一致，并由此导致了两种截然不同的观点：一部分学者报告的喉癌标本中HPV阳性率高达50%~90%，并显著高于喉良性肿瘤，认为HPV与喉癌有关；而另有不少学者检测的样本中，阳性率（5%~43.3%）并不比正常喉粘膜及良性肿瘤高，认为HPV与喉癌无关，因此，HPV到底是不是喉癌的致癌因素目前仍无定论。

The effects of phenolic acid compounds in vegetables and fruits on metabolicactivation of BaP in rats,as well as 〓 and TCA induced lipid peroxidation inmouse and Salmonella typhimurium TA104 cells were investigated using DNAadducts as a biomarker to assess DNA damage induced by xenobiotic carcinogens.BaP was used to study the genotoxic carcinogenesis,while 〓 and TCA were usedto study the non-genotoxic carcinogenesis.The possible protection mechanisms ofphenolic acid compounds on DNA damage were studied.

本研究根据化学致癌过程的遗传毒性和非遗传毒性机理，以DNA加合物作为机体接触外来化学物而导致DNA损伤的生物学标志物，通过观察酚酸类化合物对大鼠体内BaP活化代谢以及〓和TCA诱导小鼠肝微粒体脂质过氧化的影响，及酚酸类化合物对BaP和TCA诱导的沙门氏菌TA100和TA104形成DNA加合物的影响，探讨蔬菜、水果中酚酸类化合物对外来化学物诱导的DNA损伤的保护机制。

In conclusion, tobacco specific carcinogen, NNK, enhanced colon cancer metastasis through α7-nAChR and E-cadherin — one of the hallmarks of epithelial mesenchymal transition — and its transcription repressors, Snail and ZEB1. Besides, the nicotine also enhanced the colon cancer cell migration through non-E-cadherin pathway.

从我们的实验得知菸草中的致癌物质NNK能透过结肠癌细胞上的α7尼古丁受器而改变E-cadherin转录及其转录抑制因子(Snail和ZEB1)的表现量来增加结肠癌细胞的转移能力，而尼古丁则是透过E-cadherin以外的途径来促进结肠癌细胞转移。

Many people may not be aware of this compound is Shawan Yi, in fact, all of your home are used to sewer known as PVC plastic pipe, while the manufacture of vinyl chloride materials, the plastic pipe that we know the most powerful cancer-causing chemicals.

很多人可能不知道这个化合物是啥玩意，其实您家里所有的下水道都是用的叫PVC的塑料管，而制造这个塑料管的材料氯乙烯就是我们所知道的最厉害的致癌化学物质。

The study on themechanisums has been a hotspot of biology and radiobiology.

值得关注的是，自从国外学者提出电离辐射旁效应概念以来，许多研究者证实旁效应的存在，对&照射细胞核才会引起细胞致命的损伤&&只有受照射细胞才受到损伤&等某些传统观念提出了有力的挑战，辐射诱导的基因不稳定性、细胞质受到照射所致的突变及旁效应等在辐射致癌中同样具有重要作用，并得到放射生物学界的确认。

Complete haematological remission at baseline was reported in 114 patients, the remaining, 76.2% achieved complete haematological remission in 1 month.

Bcr-Abl蛋白是由含有异常的费城染色体的细胞产生的，在患有CML的患者中，这种蛋白质被认为是致癌白细胞过度增殖的一个重要因素。

So far there are over 90% of the nitroso compounds that have different levels of carcinogenicity and marked organophihsm in over 300 nitroso compounds that people have studied, So they attrack many scholars to pay more attention to it and attach great importance to the in-depth study, The winters ummarize the physical and chemical nature, the food source, carcinogenic effect and preventive measures.
