BACKGROUND: In recent years, nanoparticles has been rapidly developing in tumor hyperthermia, genophore research, and targeted drug therapy, particularly nanoparticle containing drug delivery systems will become another breach in tumor therapy.OBJECTIVE: To summarize the application and mechanism of superparamagnetic nanoparticles for cancer treatment in the medical field.METHODS: A computer-based online search was conducted in Medline for English language publications containing the key words of "superparamagnetic, nanoparticles, targeting" from January 2000 to October 2009. Relevant articles were also searched from CNKI with the same key words in Chinese from January 2005 to October 2009.RESULTS AND CONCLUSION: A total of 123 articles about targeting role of magnetic nanoparticles were included, and there were 24 in Chinese and 108 in English. Articles published earlier, duplicated, and similarly were excluded, and 30 references were finally included. Superparamagnetic nanoparticles characterized by targeting role under external magnetic field, and crystal of ferroso-ferric oxide did not has toxicity to cells. As a gene carrier and drug carrier, superparamagnetic nanoparticles were widely used in medical research and they also provided novel evidences for cancer treatment. By an external magnetic field, how to avoid a comprehensive system of phagocytic endothelial phagocytosis and prevent the course of treatment such as drug-induced thrombus is still inadequate.

The effects of synthetic oil used as dietary fat source on the body weight, organ weight, liver and serum lipids of rats during the hypercho-lesterolemic inducing period were investigated, and comparison was made with lard and soybean oil diets.Weanling albino rats were fed first with stock diet for 3 weeks. Bloods were collected from tails, and serum cholesterol contents were determined. Based upon the body weight and serum cholesterol level, animals were then divided into 5 groups. Four groups were fed respectively with synthetic oil, synthetic oil plus linoleic acid, lard and soybean oil diets, all were supplemented with 1% cholesterol. The, fifth group served as control, was fed with soybean oil diet without cholesterol. Body weights and serum lipids (cholesterol and triglyceride) were measured at intervals during the experiment. Organ weights and liver lipids (total fat, cholesterol and triglyceride) were determined at the end of the experiment.The results showed that there was marked sex difference between male and female rats, that is, synthetic oil diet caused significant lower body weights and lower serum cholesterol levels to female but not to male rats.Cholesterol inducing diets apparently increased the liver weights of all animals, yet fat accumulation only occured in those livers of rats fed with lard and soybean oil diets. The liver fat contents of animals of both synthetic oil and synthetic oil plus linoleic acid groups were at normal level.This experiment reveals that when dietary cholesterol intake is high, the use of synthetic oil as a dietary fat source for maintaining a normal lipid metabolic condition in the body seems beneficial.
