As well known there exist complex interaction between the trace elements, and the trace elements and other substances, so the trace element research must be involved to the com-prehensive effect of multifactors, other than single element. We determined the contents of fifteen trace elements in serum from thirty patients with liver cancer and thirty healthy adults by ICP-AES analysis. The obtained data were analysed statistically by not only routine statistical test bat also multi-variate discrimination analysis, multi-variate stepwise regression and non-linear mapping algorithm. It is hoped that it can provide some valuable informations for investigation on relationship betwecn trace elements and cancer.展开更多

The three main reasons for the low cancer curative rates in China include differences in the spectrum of cancer types, in early detection rates, and in the percentage of cancer patients receiving standardized treatment between China and developed countries.The most important mechanism for improving the curative rate is to improve early detection rates of major cancers in China using novel and affordable technologies that can be operated at home by the patients themselves.This attempt could be helpful in setting up a practical example for other developing countries with limited medical resources and a limited number of healthcare practitioners.展开更多
