KLF6在肿瘤中的研究进展

随着科学技术的不断发展,人们对肿瘤的认识不断加深。KLF6是一种在哺乳动物组织中普遍表达的核转录调控因子,参与生长发育、细胞分化、生长信号的转导、细胞增殖、凋亡和血管形成等过程。研究表明,KLF6作为肿瘤抑制基因,在肿瘤的发生发展中起重要作用。文章从KLF6的结构功能、在肿瘤发生发展中的作用、肿瘤中的失活机制及KLF6在恶性肿瘤等方面进行综述。

Changes in the anterior segment of the eye in workers in the coke manufacturing industry

An investigation carried out of eye disorders in workers employed in the manufacture of coke demonstrated a high percentage of changes in the anterior segment of the eye. Registered symptoms such as conjunctival hyperemia, pinguecula, pigmentation and conjunctivitis were most probably connected with specific work and exposure to coal dust and irritants. In workers exposed for less than two years there were no changes in lacrimal secretion. In those working for 2-7 years excessive hypersecretion dominated, and after a longer period of exposure the majority of workers had hyposecretion.     

Atebrin in the treatment of malaria in the Sudan

Cases of benign and malignant tertian malaria have been treated with different amounts of atebrin cum plasmoquine.No recurrence was noted up to three months in cases of benign tertian treated with 0·3 gramme atebrin and 0·03 gramme plasmoquine for five days but the probable relapse rate in malignant tertian treated in this way was practically 15 per cent.Cases of malignant tertian malaria treated with 0·2 gramme atebrin cum 0·02 gramme plasmoquine for 8 days did not relapse in a period up to three months, and toxic symptoms were very slight. It is suggested that the difference in the results of treatment is due either to the co-operation or failure of body resistance in assisting the drug.     

Mortality in the workers in the tire industry]

The article is concerned with a study of the mortality rates among the workers engaged at a tire-producing plant, for the 1950-1979 period. In comparison with the control population group, the contributors revealed increased mortality rates caused by cardiovascular diseases, malignant neoplasms, accidents, intoxications and traumas. Analysis of the labour conditions proved the influence of the unfavourable occupational factors on the mortality rates and mortality causes, excepting the indices of mortality caused by accidents, intoxications and traumas.
