Background: Polyamine biosynthesis is controlled primarily by ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase (AdoMetDC). Polyamine concentrations are elevated in colorectal cancer. Depletion of polyamine content in colorectal cancer by chemotherapy is related to tumor regression and impaired tumorigenicity.

Methods: A 205-bp cDNA of AdoMetDC was reverse-inserted into recombinant pAdTrack-ODCas vectors and recombined with pAdEasy-1 vectors in AdEasy-1 cells. Positive clones were selected and transfected into the packaging cell HEK293 after they were linearized by PacI.

Objective: To investigate the effect of arterial elongation on the arteries and to set up a new method for vessel repair.
Methods: This study was performed in 24 arteries that underwent different traumatic deficit and acute intra-operative elongation repair. The vessels were harvested and studied by histology, electron microscopy, and immunohistochemistry on day 1, 7 and 28 after operation.
Objective: To investigate fluid resuscitation affecting the result of treatment of patients with traumatic shock.
Methods: Two hundred and fifty-six cases of patients with traumatic shock treated in our hospital between January 1989 and December 2002 were analysed retrospectively, and the volume-effect relationship between fluid resuscitation during the first hour and future of traumatic shock was summarised.
Results: The successful rate of resuscitation was 73.
