OBJECTIVE To reduce the nosocomial infection rate among bone marrow transplanted patients.METHODS The related factors of infection among bone marrow transplanted patients were analyzed.RESULTS The environmental microbiology pollution,carrying opportunistic pathogens,oral mucosa damage,deep venous catheterization and others were the main related factors of infection.CONCLUSIONS The proposed control of endogenous and exogenous infection and strengthening the counter measures in the oral care and deep venous catherization care could effectively prevent nosocomial infection among bone marrow transplanted patients.

OBJECTIVE To advocate the establishment of a hospital center for intravenous drug preparation,in order to control infection caused by intravenous infusion.METHODS The unsafe factors brought by traditional distributed intravenous drug preparation were analyzed and propose the necessity and importance of the establishment of pharmacy intravenous admixture center.RESULTS Without any case of transfusion reaction occurred for 3 years,the Pharmacy intravenous admixture center could ensure the safety of patients.CONCLUSIONS Pharmacy intravenous admixture center plays an important role in providing the aseptic environment,shortening the preparatory time after the liquid stored and ensuring that the liquid is not contaminated.

This article reviewed key genes that involved in fatty acid synthesis and triacylglycerol assembly pathway. The transcription factors which play important roles in seed development and oil content were also reviewed. We summarized the achievement in modifying fatty acid composition and increase oil content in plant by gene engineering using these genes.
