Methods Data were obtained from the GLOBOCAN 2008 database.Estimated numbers of new cancer cases in the USA were obtained from the American Cancer Society,while the numbers of cases in China,including those in urban and rural areas,were obtained from 36 cancer registries(2003-2005).Cancer incidence for major sites between China and the USA were analyzed. Results In China,lung cancer was the predominant type of cancer detected in males;in females,breast cancer was the main type of cancer.Gastrointestinal cancers,such as those of the liver,stomach,and esophagus,were more commonly seen in China than in the USA.A significant difference in the incidence of melanoma of the skin was observed between China and the USA.During comparison of differences in the age-standardized rates by world population(ASRWs) of major cancer sites between the two countries,4 sites in males(i.e.,nasopharynx,esophagus,stomach,and liver) and 6 sites in females(i.e.,nasopharynx,esophagus,stomach,liver, gallbladder,and cervix uteri) showed higher cancer incidence rates in China than in the USA. Conclusions Significant differences in cancer incidence sites were found between the two countries.Cancer may be prevented through public education and awareness.Programs to promote cancer prevention in China,especially those of the lung,breast,and gastrointestinal region,must also be implemented.展开更多

From the development side, based on the experience of relevant experience of developed countries and some regions of the experiment, the mechanization of agriculture can contribute fully to the development of agriculture and other aspects of the scale. Thus, agricultural mechanization can be said that the latest form of agriculture in the 21st century. But from a practical point of view, although the mechanization of agriculture has unparalleled advantages, but also in the process of operation exposed a lot of problems.展开更多

The study was designed as randomized clinical intervention to explore the potentials of natal plum to combat against IDA (iron deficiency anemia)/anemia using mean HB gains as a parameter. The research was carried out in rural setting near Somalia capital where local NGOs (non governmental organizations) work in the absence of local/central authorities. Only HB levels of the subject children were measured as other confirmatory analyses were not available due to the civil wars at the time of the intervention. The baseline HB levels of both groups were similar. However, after the intervention the cumulative HB levels of the natal fruits group was higher than the control group of ferrous sulfate by at least 31% (P 〈 0.008, equal variances not assumed). Dietary interventions to mitigate IDA/anemia using locally available foods rich in iron, vitamins C and A seem to promise in the developing countries where chronic inadequate resources seem to affect the public health nutrition especially vulnerable groups like growing children.展开更多
