INTRODUCTIONMessenger RNA differential display technique, developed by Dr. Liang in 1992[1], is a powerful new tool for identifying and cloning differentially expressed genes in a certain type of cell line, tissue or a special developing stage. Using this method, large amounts of molecular biological information can be obtained easily and quickly. In our study, this technique was used to compare genes expressed differentially between normal colon mucosa and colon carcinomas, in order to understand the molecular biological basis of colon cancer.

It is well known that treatment with exogenous surfactant works well in premature infants with lung surfactant deficiency. Effects of surfactant therapy are less dramatic when used to treat lung diseases associated with acute lung injury(ALI)and adult respiratory distress syndrome(ARDS). This less successful clinical response may be due in part to surfactant inactivation by leakage of plasma and inflammatory products into the alveoli. It is therefore important to find a way of preventing or reversing inactivation of surfac-

The properties of bone tissue engineering scaffolds such as architecture, porosity, mechanical properties and surface properties have significant effects on cellular response and play an important role in bone regeneration. In this study, threedimensional nanocomposite scaffolds consisting of calcium phosphate （Ca-P） nanoparticles and poly（hydroxybutyrate-co-hydroxyvalerate）（PHBV） copolymer with controlled external and internal architectures were successfully produced via selective laser sintering （SLS）, one of the versatile rapid prototyping techniques. The Ca-PIPHBV nanocomposite scaffolds had a porosity of （61.75±1.24）%, compressive strength of （2.16±0.21） MPa and Young＇s modulus of （26.98±2.29） MPa. The surface modification of scaffolds by gelatin was achieved through physical entrapment. The amount of entrapped gelatin could be controlled by varying the solvent composition and reaction time. The surface modification improved the hydrophilicity of scaffolds but did not significantly affect the surface morphology and mechanical properties. Osteoblast-like cells （SaOS-2） were cultured on scaffolds with and without gelatin surface modification. The majority of SaOS-2 cells were viable and proliferated in both types of scaffolds for up to 14 d in culture, as indicated by MTT assay and live and dead assay. Surface modification significantly increased cell proliferation for surface modified scaffolds, which could be due to the improvement in hydrophilicity of the scaffolds.
